Comprehensive knowledge of hotel water and electricity installation (including water and electricity construction technology)

During the hotel decoration process, water and electricity installation is only one part of the hotel's interior decoration, but it is very important. The water and electricity installation in the hotel is different from the water and electricity installation or water and electricity renovation in the home decoration. There are many factors to consider during hotel installation, and the project volume is much larger. In this article, the editor of Tubatu mainly explains the knowledge of hotel water and electricity installation.

1. Preparations before hotel water and electricity installation

1. Have detailed hotel water and electricity installation construction design drawings

Hotel water and electricity installation requires an overall understanding of the entire space Water and electricity installation layout and wiring, including cooling water, exhaust, drainage, water supply, lighting, etc. These need to be fully considered during design, and construction must be carried out in strict accordance with the water and electricity installation design drawings during the construction process.

2. Mobilization and arrangement of construction personnel

Before the hotel water and electricity installation and construction process, it is necessary to arrange the water and electricity installation personnel, determine the construction period, and professional construction personnel and management personnel.

3. Determination of construction materials and processes

The hotel water and electricity installation materials and construction processes must be standardized and implemented in accordance with the construction materials and contracts.

2. Hotel electrical installation construction technology

1. Hotel electrical wiring

The laying of wires should meet the design requirements, and piping (metal piping or plastic pipes can be used ), sheathed wires and other laying lines. Ordinary insulated wires shall not be laid exposed.

(1) Hotel electrical installation piping and wiring

Select piping, connect pipes, have smooth pipe mouths, and complete mouth guards. The piping should be fixed, neatly arranged, and the boxes (boxes) should be set correctly. The fixing is reliable; the distance between electrical pipelines and steam pipes and hot water pipes, and the pipelines laid on the ceiling should be fixed and reliable, and the distance from the ceiling should be greater than 50 mm;

(2) Sheathed wire wiring

It is strictly forbidden to have defects such as kinks, dead bends, damaged insulation, broken sheaths, etc. It is strictly forbidden to lay directly buried in alkaline materials such as plaster layers. The wiring should be straight, neat, and reliably fixed. It should pass through beams, walls, There should be protective tubes on floors and other places.

(3) Installation of lighting fixtures and switches and sockets

The selection of lighting fixtures should meet the design requirements, and the contact points between appliances that generate large amounts of heat and combustible materials should be heat-insulated. ; Sockets and switches are installed securely with no gaps around them; sockets installed below 1.5m2 should use sockets with anti-shock protection measures; switches installed in kitchens and bathrooms should use switches with waterproof measures; the model and wire diameter of the wires should comply with Design requirements: The wires are connected tightly and the connector head is pulled tightly; the wires are tightly wrapped so as not to damage the wire core, and the wires are free of defects such as kinking, kink, dead bends, and damage to the insulation layer.

2. Installation of wall lamps

(1)? Determine the installation position

Generally, the height of wall lamps is 1440~1850mm from the working surface, that is, 2240mm from the ground ~2650mm, the wall lamp in the bedroom can be closer to the ground, about 1400~1700mm; the distance between the wall lamp and the wall is about 95~400mm.

(2)? Installation method

The installation method of wall lamp is relatively simple. After the position is determined, the main thing is to fix the wall lamp holder, which is often embedded or punched. Method, fix the wall lamp on the wall.

(3) Chandelier installation

Large chandeliers are installed on structural layers, such as floor slabs, roof trusses and beams. Small chandeliers are often installed on shelves or reinforced shelves. On the fence.

Construction materials: wood, aluminum alloy, mainly used as supporting components, plastic, plexiglass plates, glass as spacers, exterior decorative veneers and heat sinks, copper plates, anodized aluminum plates as decorative components, other accessories such as Screws, nails, rivets, finished lamps, adhesives, etc.

Construction tools: pliers, screwdrivers, hammers, electric jig saws, electric hammers, hand tools, rulers, paint brushes, etc.

How to connect hanging cups, slings and structural layers: mainly consider the connection of embedded parts and transition parts.

Installation precautions: The location and length of the suspended ceiling. The suspender can be directly removed from the ceiling surface or added with a casing. The suspender should have a thread of a certain length for height adjustment. When hanging a light box under a sling boom, attention should be paid to the reliability of the connection.

3. Installation of ceiling lamps

(1)? Classification of ceiling lamps

Ceiling lamps are classified according to structure: there are two types: raised type and embedded type ;

Ceiling lamps are classified according to the shape of the lampshade: spherical, hemispherical, oblate, flat, square, rectangular, rhombus, triangle, cone, olive and pendant. ;

(2)? Ceiling lamp installation method

Material preparation: Refer to the chandelier installation for material and tool selection.

Operation method:

Ceiling opening: First use small joists to connect the size of the ceiling lamp opening to form a hole frame. This frame provides connection points for the lamps.

Connect the hanging bars to the lamps: Small ceiling lamps can only be connected to the joists. Large ceiling lamps must have separate hanging bars from the structural layer. The hanging bars should be arranged during floor construction. The method of burying them is Same as the ceiling reinforcement method.

Architectural ceiling lamps: often use non-finished lamps, but ordinary fluorescent lamps, incandescent lamps plus grid glass, organic glass, polystyrene plastic crystal sheets, etc., to assemble large-area ceiling lamps .

(3) Installation precautions

Before construction, the form (shaped product, assembled type), size, and connection structure of the lamp should be understood in order to determine the location of the embedded parts and the size of the opening position. . Large ceiling lamps must be hung separately, and the hanging ribs cannot be repaired after nailing.

Be familiar with the floor plan and node details of ceiling lamps, and study the lighting fixture layout and node details, as well as lamp samples.

At the junction between the ceiling lamp and the ceiling panel, the edge component of the ceiling lamp should press the panel or cover the panel seam.

For the glass surface of the assembled ceiling lamp, you can choose diamond-shaped glass sheets, polystyrene crystal sheets, or perform surface treatment such as turning and grinding on ordinary glass and plexiglass to increase refraction and reduce transmittance to avoid Dark light.

3. Installation and construction technology of sanitary ware and pipes

1. Installation of sanitary ware

(1) The model, specification and quality requirements of sanitary ware should comply with Design or engineering contract (engineering agreement) requirements.

(2) The installation position of sanitary appliances should meet the following requirements:
