Description

Special wire box for prefabricated laminated board

technical field

The utility model belongs to the technical field of prefabricated laminated panels, in particular to a special line box for prefabricated laminated panels.

Background technique

In building construction, the roof light box is an indispensable and important part, which ensures the normal use of roof lighting equipment, while the wire box used in the construction process of prefabricated laminated panels in the prior art is a finished PVC octagonal box, and its height Can not meet the construction requirements.

86 series PVC octagonal box is generally used for the junction box of lamps and lanterns. This kind of junction box is divided into 86h70 and 86h50 series, that is, the height of the junction box is 70mm and 50mm. This makes part or all of the pipe outlet at the junction box immersed in the concrete. In the process of making the laminated board, it is necessary to use a curved wire pipe in the shape of "B" so that the pipe is exposed to more than 60mm. This method may cause damage to the wire pipe and the connection between the wire pipe and the wire box during the process of manufacture and construction. Once damaged, the pipeline needs to be manually shaved, which creates unnecessary labor costs.

Utility model content

In order to avoid damage to the line pipe during production and construction, and achieve the purpose of saving labor costs. The utility model provides a special wire box for prefabricated laminated boards, and its specific technical scheme is:

A special line box for prefabricated laminated boards, which includes a bottom box and a top box. There are reinforcement holes; the upper part of the bottom box is provided with internal threads, and the lower part is provided with screw fixing grooves; the top box is composed of a top plate and a box body, both of which are provided with pipe holes, and the lower part of the box body is provided with external threads.

This structure is used to separate the pre-embedded part and the wire pipe installation part to achieve separate construction, effectively avoiding the problem of wire pipe bending when the wire box is pre-embedded in the prefabricated production process of the laminated board, and avoiding the alignment of the wire box during construction and hoisting damage, thereby improving work efficiency and saving engineering costs.

Detailed ways

The utility model is further described below:

As shown in Fig. 1-5, a special line box for prefabricated laminated boards includes a bottom box 1 and a top box 2. The bottom box 1 consists of a box wall 11 in the shape of a through tube and two A steel bar piercing block 13 is formed, and a steel bar hole is provided on the steel bar piercing block 13; the bottom box is provided with an internal thread 12, and the bottom is provided with a screw fixing groove 14; the top box 2 is composed of a top plate 22 and a box body 21, and the top plate 22 All be provided with pipe hole 23 on the box body 21, and box body bottom is provided with external screw thread 24.

Using the construction method of the above-mentioned special line box for prefabricated laminated panels, proceed as follows:

1) Put steel bars 4 in the steel bar holes on both sides of the bottom box 1.

2) The screw fixing groove side of the bottom box (that is, the lower side of the bottom box) is sealed with tape, the box is filled with foam, and then the opening of the threaded side (that is, the upper side of the bottom box) is sealed with tape.

3) When installing the reinforcement 5 of the laminated plate, bind the bottom box to the reinforcement 5 of the laminated plate, so that the side of the screw fixing groove of the bottom box is closely attached to the template. Refer to Figure 1 for the complete picture of this step.

4) Concrete pouring, the whole box wall of the bottom box 1 is poured in the concrete, the screw fixing groove side of the bottom box is flush with the lower surface of the laminated plate, and the threaded side is exposed on the upper surface of the laminated plate. Specifically, the threaded side can be flush with the upper surface of the laminated board, or slightly higher than the laminated board.

5) After the laminated board is transported to the site, take the top box 2, and install the wire box lock nut 3 on one or more pipe holes 23 on the top box according to the design of the wire pipe.

6) Finally screw the top box 2 into the bottom box 1. The complete picture of this step is shown in Figure 6.

In the special wire box for prefabricated laminated boards provided by the utility model, the bottom box 1 should be pre-buried in the laminated boards, and its size should be adapted to the thickness of the laminated boards. Specifically, the height of the bottom box 1 provided by the utility model is 60mm-70mm, and the height of the top box 2 is 50mm.

The position of the steel bar piercing block 13 may be at the lower part, the middle part or the upper part of the bottom box 1 . It is preferably set in a position flush with the bottom of the box.

Preferably, the height of the inner thread 12 of the bottom box accounts for one-third of the total height of the box wall 11 . The height of the external thread 24 of the top box 2 accounts for 1/5th of the height of the top box body 21 . But the screw thread is not limited to this range, and the screw thread has a wide range to meet the requirement that the top box can be fixed in the bottom box without shaking and not easy to come out. Theoretically, the larger the thread, the more secure the bottom box and top box are fixed.

Three pipe holes are arranged on the top plate of the top box, and four pipe holes are uniformly arranged on the body of the top box. The through-pipe hole is provided with a baffle, and the baffle has small connection points connected with the top box itself when the top box is not in use, and these small connection points are easily broken when the baffle is knocked. According to the design of the conduit, it is only necessary to knock off the baffles on the conduit holes that need to be used.

This plan will design the pre-embedded box body part and the wire pipe installation part. The wire box pre-embedded and the wire pipe installation are carried out separately, which can effectively avoid the bending of the wire pipe when the wire box is pre-embedded in the prefabricated production process and the damage to the wire box during the construction and hoisting process. Destruction, thereby improving work efficiency and saving engineering costs.
