Description

A fully decorated strong and weak current sheath system

【Technical field】

The invention relates to the technical field of building materials for building indoor strong and weak current sheath systems, in particular to a fully decorated strong and weak current sheath system.

【Background technique】

In home decoration, both strong and weak wires need to have protective sleeves to prevent the wires from being damaged and damaged. Generally, PVC plastic pipes are used as the sheath tubes. The sheath pipe system mainly includes sheath pipe and fittings. The sheath pipe is a plastic pipe with a circular cross-section; since the wire needs to be drawn into the casing by a steel wire after the pipe is laid, products with "sharp turns" such as tees and elbows cannot be used. , When it is necessary to turn, a special spring is generally used to penetrate the inside of the pipe to assist in bending the pipe. The fittings used in the pipe system are mainly direct products, which are used for the extension and connection of the pipe in the straight direction.

During the construction of the wire sheathing pipe, there are two ways for the direction of the main part (from the distribution box to the wire sheathing pipe of the branch line branch). One is to walk in the floor, and the other is to walk in the ceiling or sideways. The upper part of the wall; the part of the branch pipe (from the ceiling or the ground to the end part of the wire sheath of the switch or socket) needs to be slotted and concealed on the wall, and the main part and the branch part are generally realized by a pipe with the same outer diameter of. Since the decoration of the fully-decorated house is carried out simultaneously by the developer during the construction of the house, there is no cement leveling layer on the floor. It can walk in the ceiling or the space above the side wall. The specific construction and installation steps are summarized as follows:

1. Spring line: Use the ink fountain to pop out the line direction, and mark the position where the slot needs to be slotted.

2. Grooving: Cutting the lines that need to be buried on the wall.

3. Pipe layout: Lay and install the pipeline according to the design direction.

4. Threading: thread the wire into the electrical casing.

5. Groove filling: fill the electrical casing with cement.

In the traditional practice, the prominent problems are the cumbersome construction process and high labor costs, which are mainly manifested in the following aspects:

1. There is a lot of dust and noise in slotting

Slotting needs to use a special hand-held slotting machine to cut 2 parallel grooves, and then use a hammer or chisel to remove the middle part. During the construction process, dust and noise pollution are serious. Generally, plumbers do not do the slotting themselves. Tank crew construction.

2. The turning of the pipe needs to be bent with the help of a special spring

In order to meet the needs of threading in the later stage, when laying pipes, the pipes should avoid sharp turns, and turning accessories cannot be used. The pipes can only be bent manually with the help of special springs, which is labor-intensive and time-consuming.

3. High pipeline fixing requirements

Due to the high threading resistance, it is easy to pull the wire pipe off when pulling the wire, so the pipe must be fixed firmly. The traditional U-shaped pipe clip cannot meet the needs. Generally, a semi-circular pipe clip is used, and two holes need to be drilled on the wall or the top plate. Secured with two expansion tubes.

4. A lot of routing boxes are needed at the turn on the top plate

In order to meet the needs of threading in the later stage, a crossing box is needed at the turn as a "transfer station" for threading, especially the lintel part of the wire pipe needs a large number of crossing boxes.

5. Time-consuming threading

In order to meet the needs of threading in the later stage, when laying pipes, the pipes should avoid sharp turns, and turning accessories cannot be used. The pipes can only be bent manually with the help of special springs, which is labor-intensive and time-consuming.

To sum up, taking a 120-square-meter three-bedroom apartment as an example, the installation of electrical bushings generally requires 10 labors. According to the current labor cost, it is about 3,000 yuan in labor costs. Full decoration has the advantages of high efficiency and energy saving. The country is vigorously promoting full decoration, which is a trend; today, with higher and higher labor costs, the problems of circular sheath pipes are becoming more and more prominent. Therefore, it is necessary to propose a fully decorated strong and weak current sheath system.
