Who knows the whole process of hotel decoration?

1. Decoration measurement and setting out

1. Before construction, construction technicians and stakeout personnel conduct on-site measurement and stakeout, and use ink lines to draw out the decorations according to the design drawings. The construction can only begin after checking whether there are any errors between the site and the drawings.

2. Measure an elevation line of 50cm on each level and pop up an ink line on the wall as the standard benchmark for interior decoration. The measurement error is ±3mm.

3. Steel nails are used as stakeout confirmation points on the ground, and the top surface of the wall is marked with paint.

2. Electrical construction

1. Indoor power distribution

(5) The internal wiring cross-section of the distribution box should comply with the specification requirements.

3. Light steel keel gypsum board suspended ceiling

1. The base layer of the suspended ceiling must have sufficient strength. Clear ceiling and surrounding obstructions. Ventilation, water and electricity pipes and other hidden projects in the suspended ceiling should be installed, and the fire protection system should be installed and pressure tested. When installing and transporting suspended ceiling keels, they must not be thrown, dropped or collided. The keel should be laid flat to prevent deformation. The surface should be smooth, the edges should be neat, and the color should be uniform.

2. According to the design elevation of the ceiling, stretch the line along the perimeter of the wall as the standard line for ceiling installation. The allowable horizontal deviation is within ±5mm. Determine the installation position of the edge keel and fix the edge keel at all around the walls.

3. Draw the top position line of the suspender on the ceiling, find the symmetrical cross lines on the ceiling, and draw a number of horizontal and vertical intersecting lines according to the grid size of the ceiling keel as a fixation for the fixed suspender. point, use internal expansion bolts to firmly fix the boom to the ceiling. The boom should be No. 8 full-bolt pattern boom, and the spacing between the booms should not exceed 1200mm. When the boom meets top equipment and pipelines, the position of the hanging point should be adjusted and a boom added.

4. Fix the hanging piece under the boom, pull the wire according to the height of the side keel, and review and adjust the height of the boom to the appropriate position.

5. Place one end of the load-bearing keel on the edge keel, hang the load-bearing keel with a hanger, and fix it with screws. The load-bearing keel is connected, and the main keel connector is used to connect and extend. The spacing between the main keels is generally 900-1200mm. The middle part should be arched, and the arching height should not be less than 1/200 of the short side span of the room. After the main keels are installed, their position and elevation should be corrected in time. Light lamps should be hung on the main keel or additional keel. Heavy lamps or other decorative parts must not be connected to the ceiling keel, and separate hooks should be provided.

6. Comprehensively correct the position and level of the primary and secondary keels. After correction, tighten all hanging parts and connecting parts. Connectors should be installed misaligned.

7. The installation of various pipelines must not damage the keel system or be directly installed on the keel. After the pipeline is accepted, the cladding panel can be installed.

8. The panel should not have bubbles, peeling, cracks, contamination and incomplete patterns.

9. The gypsum board should be installed along one end of the suspended ceiling. The long side of the gypsum board must be installed vertically to cover the keel. The short side seams of the gypsum board should be staggered and no through seams should be formed.

10. Use gypsum board self-tapping screws to fix the board surface and the keel; use an electric screw gun to drive the self-tapping screws into the gypsum board at one time. It is appropriate for the nail head to be embedded in the gypsum board by 0.5mm-1mm, and the paper surface should not be damaged. , exposing the plaster. Install self-tapping screws along the overlocking edge. The distance between the self-tapping screws and the edge of the board is 10mm-15mm. Install the self-tapping screws along the cut edge. The distance between the self-tapping screws and the edge of the board is 15mm-20mm. The distance between the screws is 150mm-170mm. The connection between the gypsum board and the keel should be fixed from the middle of the board to the surroundings. Simultaneous work at multiple points is not allowed to avoid stress and uneven laying. Apply anti-rust paint to the nail heads and smooth them with caulking paste.

11. Seam treatment: Clean the seams and remove debris. Fill the caulking paste into the seams of the board and apply it tightly. The thickness should be level with the board and should not be higher than the board. After it solidifies, apply caulking paste on both sides of the board seam. Each side should be no less than 50mm. Paste the seam tape on the board seam. Use a spatula to flatten and compact it. There should be no air bubbles between the paper tape and the caulking paste. . Make the center line of the paper tape coincide with the center line of the board seam, and the width of the paper tape on the board surfaces on both sides of the seam is equal. Scrape the caulking paste pressed out from the edge of the paper tape onto the paper tape, smooth and compact it so that the paper tape is buried in the caulking putty.

4. Light steel keel gypsum board partition wall

1. According to the requirements of the drawing, pop up the vertical line connecting the partition wall and the wall; mark the installation position of the upper and lower keels, and mark the door , windows and other locations.

2. Install the keels along the ground, top and sides: the horizontal keels are connected to the roof and ground of the building and the vertical keels are connected to the walls and columns, and are fixed with metal expansion rivet bolts. The distance between fixed points is arranged at 600mm.

Where the surface of the light steel keel contacts the building base, it is generally required to bond a long rubber strip or sealant on both sides of the keel contact surface to provide waterproofing and sound insulation.

3. Install vertical keels: The length of the vertical keels is 5mm shorter than the net height of the partition wall, and the spacing is 400mm. When installing the vertical keels, they should be arranged starting from one end of the partition wall. If there are doors and windows, they should start from the door and window openings and expand to both sides. When the distance between the last vertical keel along the wall and the columns is greater than the keel spacing specified in the design, another vertical keel must be added. Push the pre-cut vertical keel between the top and ground keels, position the flange toward the cover panel, and fix it with the horizontal keel with self-tapping screws. When installing, please note that the height of the through holes of each keel must be at the same level. The vertical keels at the door and window openings are double-rooted and reinforced with keels.

4. Install the through keels: The distance between the through keels is 1500mm. The through keels pass through the through punching holes on each vertical keel. When connecting the length, use connectors to connect the lengths. Install the bracket on the opening surface of the keel and lock it with the through-cross brace keel. If necessary, add an angle bracket on the back of the vertical keel and fix it with the through-keel.

5. Install transverse keels: When the partition wall frame exceeds 3m in height, transverse keels should be added, and the brackets and angle brackets should be used to connect and fix the vertical keels.

6. Installation of gypsum board: Before installation, strengthen measures should be taken for the pipe fittings in the pre-embedded partitions and related wall-attached equipment. Install the paper-faced gypsum board on one side of the frame, and install the gypsum board used as a partition vertically, with its long side joints falling on the vertical keel. The gypsum boards on both sides of the keel should be staggered. The plates should be made of whole plates. If they need to be connected, they should be close together, but they should not be forced into place. After the upper and lower ends and vertical sides are in place, a 3mm gap should be left between the upper and lower floor slabs and wall column surfaces respectively. The gaps with the roof and floor should be filled with caulking paste first and then laid. Squeeze the caulking paste to It is closely connected with the light steel keel. The screws sink 0.5mm-1mm into the board surface without damaging the paper surface and exposing the plaster. Install self-tapping screws along the seam edge. The self-tapping screws should be 10mm-15mm away from the board edge. The screw spacing should not be greater than 200mm on the four sides and 300mm in the middle. . After installing the gypsum board on one side of the partition wall, fix the wiring pipes to be installed in the wall on the keel according to the design. The junction box can pass through the through hole on the keel. The junction box can be installed by opening a hole in the wall. Up to 2 junction box holes can be opened between every two vertical keels on the same wall. The distance between the hole and the vertical keel is 150mm. ; The two junction box openings must be staggered up and down, and their vertical and horizontal distance shall not be less than 300mm. If the distribution box is installed in the wall, an auxiliary keel can be installed horizontally between the two vertical keels. The keels should be connected and fixed with blind rivets. Electric welding is not allowed.

7. After the electrical installation is completed, if the design requires it, the sound insulation rock wool boards can be installed. The rock wool sound insulation boards should be evenly distributed in the inner cavity of the light steel keel, and the rock wool boards should be fixed with hanging nails. , to avoid falling off. Then install the gypsum board on the other side of the frame. The seams of the boards installed must not fall on the same keel as the seams of the boards on the opposite side, but must be staggered.

8. Nail head, seam and corner treatment: the same as the gypsum board ceiling treatment process.

5. Stone veneer

1. Base layer treatment: The corners of the bonding base layer should be cleaned and smoothed to ensure that the board can be placed in place, and the protruding parts should be chiseled away. And remove debris and dust from the wall.

2. Hang it vertically, set it squarely, and find the rules: Lead the outer contour line of the facing from the wall according to the design requirements, and label the height test blocks on the height and left and right ends of the large surface, and pull through the line. Determine the bond control line.

3. Trial arrangement and material selection: Determine the brick arrangement plan based on the overall size, stone specifications, and seam width.

4. Apply bottom mortar. Moisten the base layer with water in advance, and wait for it to dry slightly. First apply the glue interface agent plain cement once and then apply the base layer; use 1:3 cement mortar as the base mortar, with a thickness of about 12mm. Work on both sides, with the first layer about 5mm. The second pass is about 7mm. After the base ash is compacted and smoothed, roughen the surface of the base ash.

5. Veneer panels.

After the base ash has solidified, the lines can be divided into blocks. Then the wet blocks are smeared with cement slurry mixed with dry powder adhesive with a thickness of 2mm-3mm for inlaying. Use a mallet to tap lightly and use a ruler to find out. Straight against the flat.

6. Surface hooks and seams. After bonding, wipe off the surface mortar with clean water in time, wait 24-48 hours, and then perform jointing and wiping treatment.

6. Wall tile finishes

1. Base layer treatment: Clean the mortar and debris on the wall, and remove the obvious protruding parts. The bottom mortar must be absolutely flat, and the yin and yang angles must be absolutely square. Before laying the tiles, the surface of the base layer should be moistened with water, and then cement mortar should be applied to level it.

2. Elastic lines: According to the design requirements of the drawings, the horizontal and vertical decorative lines are arranged according to the door opening.

3. Apply primer: Before laying the tiles, the surface of the base layer should be moistened with water, and then a leveling layer of cement mortar should be applied. The bottom mortar must be absolutely flat, and the yin and yang angles must be absolutely square.

4. Facing brick pasting: pop up horizontal and vertical lines according to the design elevation, and then determine the width of the grid joints according to the design requirements and the specifications of the facing bricks. The tiles are laid with plain cement slurry from bottom to top and can be completed in one go. Before applying the adhesive layer, apply cement mortar to the wet bottom layer. At the same time, lay the facing bricks on the wooden pad, apply a thin layer of plain cement slurry, and then paste it. After the facing bricks of a unit are laid firmly, add cement mortar Before solidification, use a metal dial to adjust the bending and twisting gaps to make the spacing even. After all the adhesive layers have been laid and the adhesive layer has finally set, use thick white cement slurry to smooth the seams, and push and rub hard to make the seams full and dense.

7. Paint project

1. Base layer treatment: After cleaning the surface, use putty to smooth the wall surface. After the putty is completely dry, use a spatula to smooth out the excess putty and then smooth it with No. 1 sandpaper. Use paper tape to tape seams on the panel surface. Paint the nail head surface with anti-rust paint and smooth it with gypsum putty. Use inlay seam paste for the inner corners.

2. The coating process of the board surface

(1) Fully putty and polishing: After the large gaps on the indoor painting surface are filled and smooth, use a batch embedding tool to fully scrape the latex Paint putty, all tiny blisters and shrinkage cracks need to be completely scraped off, and must be dense, flat, with neat lines, corners, and edges. Scrape it horizontally along the wall in one smooth motion, trying to scrape it as thinly as possible without scraping, do not rub the joints, and do not stain doors, windows and other surfaces. Apply the putty twice in sequence. After the putty is completely dry, wrap it with No. 1 sandpaper and place it on a flat sanding rack. Smooth the putty paint and uneven areas until smooth. Pay attention to applying force evenly and protecting the edges and corners. Clean it with a broom after grinding.

(2) Apply paint: Before applying paint, the base surface must be cleaned and dust removed. The order of painting should be from top to bottom, from left to right, horizontal first then vertical, edges and corners first, small surfaces first then large surfaces. There should be no residual paint on the inner corners and no edges on the outer corners.

(3) Repair putty: After each coat of paint is completely dry, it should be inspected generally. If there are any defects, the paint putty should be patched locally.

(4) Polishing: After the repair putty dries, fine sandpaper should be used to smooth the paint surface. Pay attention to using light and even force, and do not wear through the paint film.

(5) Apply the second coat of paint.

8. Pasting project

1. Base layer treatment: The base wall surface should be smooth, and obvious uneven areas should be repaired and smoothed. Smaller pits and stains should be filled with putty. Smooth. The wall surface should be kept dry to prevent mold from forming after mounting. The walls should be cleaned and free of dust and floating dust. And apply a layer of primer on the wall.

2. The elastic line: it is required to be horizontal and vertical, and the wallpaper should be symmetrical and even in format. The first piece of paper on each wall should be stretched to find a straight line as a guideline. Starting from the second piece of paper, the seams should be pasted one by one, first up and then down.

3. Cutting: The wallpaper should be planned according to the material specifications and wall dimensions, and the numbers should be pasted in order. The cutting length of the wallpaper should be slightly longer than the size of the pasting part by 100mm-150mm.

4. Paste and paste: Choose a good location and hang the vertical line to ensure that the first piece of wallpaper is pasted vertically and flat.

The adhesive should be prepared as needed. The amount used on the day is limited. Hydroxymethylcellulose is first dissolved in water. After about 10 hours, it is filtered with fine mesh sand to remove impurities, and then mixed with other materials and stirred evenly. The thickness of the glue is suitable for mounting. Use a brush to brush the glue evenly onto the wall, then put the cut wallpaper into rolls and gradually lower it from top to bottom according to the pattern requirements. Use a wet towel to smooth the wallpaper and stick it firmly, and use a blade to cut off the excess paper at the top and bottom. . The overlapping method can be used for pasting. Place two adjacent pieces at the seam. The one pasted behind should press the previous one about 3cm. Then use a ruler and a cutter to cut through the double-layer wallpaper in the middle of the overlapping range. , tear off the two small strips of wallpaper that were cut through. For wallpapers with patterns, in order to ensure the integrity and continuity of the patterns, the splicing method can be used when mounting them, first stitching the patterns and then stitching them together. After the patterns are matched from top to bottom, use a scraper to scrape the glue diagonally to make the seams dense, then scrape out the excess glue from the seams and wipe them clean. For wallpapers with important overlapping counter flowers, the counter flowers should be mounted first. After the glue has dried to a certain extent, the remaining edges should be cut off and then scraped and pressed tightly. Use even force when using the knife. Make one straight cut to avoid knife marks. When mounting the collage, the inner corners should be overlapped, and there should be no seams at the outer corners, and the corners should be wrapped and compacted. Use the entire wallpaper in obvious areas on the wall, and use less than one wallpaper in darker or less obvious areas. The connection with the mirror line, skirting line, face and other parts should be tight without any gaps. Then apply glue evenly from top to bottom to remove air bubbles and wipe off excess glue as time goes by.

5. Trimming: If local substandard conditions are found, take remedial measures in a timely manner. If wrinkles appear on the paper surface, wipe the paper surface with a wet towel while it is still wet, smooth it with your hands, and then use a rubber roller to smooth it out. If the wallpaper is dry and knotted, it will need to be reworked and re-pasted.

To put it simply, the basic processes of hotel decoration include the above eight.
