Concrete introduction of carpet laying construction technology

In today's increasingly fast-paced society, the happiest thing about working from nine to five every day is that after a busy day, a warm home can have a rest place. Therefore, in today's society, the decoration of houses is particularly important. There are many aspects of house decoration, such as the choice of furniture, the leveling of walls and even the laying of the ground. As a place for us to rest, home helps us to be happy even if we sleep until the end. So, today we will talk about floor decoration-a concrete introduction of carpet construction technology.

Carpet laying construction technology

A, the floor carpet construction preparation

1, carpet: flame retardant carpet.

2, carpet glue, carpet seam tape, linen strip.

3. Construction tools: edge trimmer, cutting knife, scissors, paint brush, iron, elastic thread powder bag, flat shovel, trowel, etc.

Second, the floor carpet construction process

1. Sticking method: grass-roots ground treatment → actual setting → carpet cutting → glue scraping and air drying → silver pressing and laying → cleaning and protection.

2. Construction key points: Before paving, measure whether the corners are square and accurately record the angles. According to the calculated blanking size, thread is tied and cut on the back of the carpet. At the joint, the two carpets on the back of the carpet should be glued together with tape. First of all, we should trim the uneven fluff at the joint and rub the fluff at the joint repeatedly until there are no seam marks on the surface.

Scraping glue and air drying for 5~ 10 when bonding and laying? Minutes, when the glue becomes dry and sticky, lay it. After the carpet is leveled, use a felt roller to press out bubbles. Cut off the excess carpet edges and clean the pulled fibers. When you cut the carpet, you should cut it along the warp of the carpet, only the weft, not the warp. For a carpet with a backing, you should separate the fluff on the front, find out the warp and weft, and then cut it.

Third, the quality standard of floor carpet

1. Main control items: the materials, specifications and technical indicators of various carpets must meet the requirements and construction specifications. Carpet and grass-roots fixed must be firm, without curling and turning up.

2. General project: the carpet surface is smooth, without wrinkles and bulges. Flat-fell seam is smooth and dense, and flat-fell seam is not obvious in sight. The joint or junction between carpet and other floors should be straight. The fluff of the carpet should be straightened, and the surface should be clean and free of oil.

Four, the floor carpet matters needing attention

1, pay attention to finished product protection, carpet with glue, 24? Don't trample at will for hours.

2. Carpet paving requires higher ground at the grass-roots level, which must be smooth and clean, with moisture content not greater than 8% and skirting boards ready. The gap between the lower edge of the skirting board and the ground should be 2~3 larger than the carpet thickness. Millimeter.

3. Accurately measure the room size and calculate the blanking size to avoid waste.

Five, the ground plastic preparation work

1, material comes into play

2. Preparation of construction tools and instruments

3, water and electricity in place

Six, the ground plastic foundation treatment

1, polish and repair unqualified ground.

Step 2 clean up the scene

Seven, pay-off: first determine the four straight line dividing lines, pay-off in the straight line section of the sports ground, the lines should be brightly colored, based on the straight line dividing lines, pay out the inner construction lines, and then pay out the construction lines from the inside out in turn.

Eight, material polishing: the plastic material (bottom-up) is naturally laid on the ground, and the bottom surface is polished with a grinder. Function: Enhance the adhesion between the material and the base surface, and make it more firmly attached. Note: During the grinding process, the grinder should move at a uniform speed to avoid damaging the site surface.

9. Priming: Priming with professional sealant (1: 4, 2% catalyst with a/b ratio and a small amount of rubber powder). Function: (1) Prevent the bottom layer from seeping (2) Level the foundation (3) The professional bottom sealing adhesive has good adhesion with the bottom layer foundation and the upper rubber sheet, which ensures the bonding effect of the site.

X. field bonding

1. Laying rubber sheets: After the construction marking is drawn, the site will be spread from the inner edge based on a straight dividing line, aligned along the drawn construction marking, and laid in turn, with a horizontal indenter of 200? Mm is suitable, the vertical parts should be aligned and placed at 30? 60? Minutes. The functions are as follows: ① the rubber surface layer restores the material to its original state and adapts to the weather; (2) spreading a rubber surface layer at the corresponding position; ③ Quality inspection (removing damaged and uneven parts); (4) Cut all interfaces and tidy them up.

2. Glue laying: After the site is set and before bonding, roll up the site from both ends respectively, and scrape off the glue on the ground from the center of the rolled-up site in one direction. When scraping glue on the ground, the dosage of glue should be moderate and should be controlled at 0.7- 1 per square meter. Kg/m2？ Scraping should be uniform, the viscosity of adhesive should be controlled and laid at the best time.

3. Bonding: When the plastic material is bonded to the ground, the operation site should be laid very carefully, and the side of the material should be aligned with the ground construction mark. First, one side of the rolled-up part is bonded. After bonding, the other side is bonded, and the inner part is bonded first. Other laying processes are basically the same as once laying. In the process of bonding the two sides of plastic materials, the residual air at the bottom of the site should be squeezed clean. In order to ensure the firm bonding of the side surface, pry the side surface of the part with a special tool to stabilize the pressure and press the bonding interface of the side surface downwards until the glue is solidified. The square is half filled with glue and half filled with air. When athletes compete on it, air and rubber are compressed to store energy to avoid impact resistance. When the soles of the feet leave the ground, natural rubber and air expand and send energy back to the athletes.

4. Pressing surface: After the material is bonded to the ground, in order to ensure that the ground is firmly bonded to the ground and prevent the ground from warping, the edge of the bonded ground will be pressed with heavy objects, and the two sides of the ground can be pressed one by one with building red bricks. The interface between the ground and the end face of the ground should be re-treated, and the blank holder method should be adopted, but four layers of red bricks should be used, and three rows of flat bricks should be laid on both sides along the center until the glue solidifies, so as to ensure it.

5. Port cutting: When bonding the end interface, one end should be stabilized with a steel ruler and cut neatly. Shrinkage at low temperature should be considered when bonding the upper pressure level and the lower pressure level at the port, so that there is a margin between the upper pressure plate and the lower pressure plate, and the two ports should be coated with adhesive, so that the bonding effect is better.

XI。 site clearing

After the site bonding is completed and the adhesive is completely cured, clean up the site, check the interface of the site port at the same time, and repair the area with weak or uneven interface in time to prepare for the next process.

Twelve, draw a line

After on-site repair and cleaning, draw lines. Drawing lines is a complicated process. In addition to ensuring the accuracy of measuring instruments, equipment and tools, construction personnel should also have a strong sense of responsibility and serious working attitude. The measurement accuracy is 1/10000, and the length verification and modification of steel ruler should be fully considered. After the dotted line is put out, three people should proofread it, and then spray the line after the proofreading meets the requirements. There should be one spinneret for each lane to ensure the uniformity and consistency of the field arc. In the process of line spraying, pay attention to clean the line spraying box in time to prevent the line spraying paint from dripping on the surface of the site, and ensure that the surface of the site is beautiful and clean.

Thirteen, clean up the scene

After all the above processes are completed, clean up the site and keep it clean.

The above is a concrete introduction to the construction technology of carpet laying. I believe everyone has a deeper understanding of how to lay carpets. Although the carpet you usually lie down or step on is beautiful and simple, there are actually many stresses and precautions in the construction technology behind it. For carpet laying, the necessary tools should be prepared first, and then the correct construction process should be followed. Although professional construction engineers are now in charge of carpet laying, it is also beneficial for us to know some steps ourselves. I hope I can help you.
