Description

Technical Field

[0001] The utility model relates to the technical field of modular house structures, in particular to a fire-proof structure in which PVC pipes pass through light steel keel walls in a modular house. Background Art

[0002] Modular houses have gradually begun to enter people's horizons, but most people are still not very clear about the concept of modular houses. The so-called modular houses are to divide the components of a house into different functional modules, and use standardized, modular and universal production to achieve factory manufacturing. The house can be assembled on site anytime and anywhere, and the whole process only takes a few hours to complete; among them, light steel keel walls are widely used in the construction field as a light enclosing wall.

[0003] At present, the fire protection treatment of PVC water pipes passing through the wall at the light steel keel fire wall is only to apply fire retardant glue at both ends of the water pipes passing through the wall. If the fire spreads, the fire can melt the pipes and spread from the inside of the water pipes to the other end of the wall, and the fire protection is not strict. Utility Model Content

[0004] The purpose of the utility model is to solve the problem of potential safety hazards in the fire protection treatment of PVC water pipes passing through the wall at the light steel keel fire wall proposed in the above background technology, and to propose a fire protection structure for PVC pipes passing through light steel keel walls in modular houses.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] The fire-proof structure of the PVC pipe passing through the light steel keel wall in the modular house includes a keel wall and a pipe body. The pipe body passes through the keel wall horizontally. The keel wall is provided with a through opening corresponding to the pipe body. The inside of the through opening and the space between the pipe body are filled with fire-proof glue. A galvanized steel plate is pre-buried at one end of the keel wall close to the through opening. Two symmetrically arranged fire-blocking strips are fixedly sleeved on the pipe body, and the opposite sides of the two fire-blocking strips are both against the keel wall.

[0007] Preferably, the galvanized steel plate and the keel wall are fixedly connected by a plurality of rivets.

[0008] Preferably, a fireproof gypsum board is fixedly connected to the outer wall of the keel wall, and the keel wall is filled with rock wool.

[0009] Preferably, the fire barrier strip, the fireproof gypsum board and the galvanized steel plate are fixedly connected by self-tapping screws.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] 1. The new PVC pipe wall fireproofing scheme, the chain type fire barrier can expand after the fire reaches a certain degree, block the pipeline hole, and the special metal buckle of the fire barrier can ensure that the fire barrier does not fall off when it works.

[0012] 2. The buckle of the fire barrier is used to punch the self-tapping drill to connect the fireproof plate and the galvanized steel plate, the overall fixing performance and fireproof performance are greatly improved, and the problem of difficult fixation of the pipeline and the fire barrier caused by the hollow of the light steel keel wall is also effectively overcome.

[0014] In the drawing: 1, the keel wall, 2, the pipeline body, 3, the fireproof glue, 4, the galvanized steel plate, 5, the fire barrier, 6, the fireproof gypsum board, 7, the self-tapping drill, 8, the rock wool. DETAILED DESCRIPTION

[0015] The technical scheme in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, not all the embodiments.

[0016] Referring to Figure 1 , the modular house PVC pipeline through the light steel keel wall fireproof structure, including the keel wall 1 and the pipeline body 2, the pipeline body 2 horizontally through the keel wall 1, the outer wall of the keel wall 1 is fixedly connected with the fireproof gypsum board 6, the keel wall 1 is filled with rock wool 8;

[0017] In this embodiment, the keel wall 1 is provided with a through hole corresponding to the pipeline body 2, the through hole is filled with fireproof glue 3 between the pipeline body 2, and the end of the keel wall 1 close to the through hole is embedded with a galvanized steel plate 4;

[0018] In this embodiment, the fire barrier 5, the fireproof gypsum board 6 and the galvanized steel plate 4 are fixedly connected through the self-tapping drill 7, and the galvanized steel plate 4 and the keel wall 1 are fixedly connected through a plurality of rivets;

[0019] In this embodiment, the pipeline body 2 is fixedly sleeved with two symmetrical fire barriers 5, and the opposite sides of the two fire barriers 5 are respectively abutted against the keel wall 1.

[0020] In this embodiment, the construction steps are:

[0021] Step 1: embed a galvanized steel plate 4 of appropriate size at the corresponding position of the pipeline body 2 through the light steel keel fireproof wall, and connect the galvanized steel plate 4 with four light steel keel rivets stably.

[0022] Step 2: After the wall fireproof plate is installed, the hole is opened on the fireproof wall plate according to the pipe body 2 positioning, the hole size needs to be larger than the pipe body 2 itself diameter by 20mm, to ensure that there is a 10mm gap to prevent fire glue 3, and the glue depth is the same as the fireproof plate thickness.

[0023] Step 3: The pipe body 2 is cut to the appropriate length, passes through the wall hole and is temporarily fixed, then the chain type fire barrier belt 3 is cut to the appropriate length according to the pipe circumference, and the buckle is connected. After the hole is glued, the buckle, fireproof gypsum board 6 and galvanized steel plate 4 are punched by self-tapping nails 7.

[0024] Step 4: The other side of the wall is the same, and the two ends of the wall are completed.

[0025] In this embodiment, the new PVC pipe wall fireproof treatment scheme, the chain type fire barrier belt 5 can expand when the fire reaches a certain degree, block the pipe hole, and the special metal buckle of the fire barrier belt 5 can ensure that the fire barrier belt 5 does not fall off when it works.

[0026] In this embodiment, the buckle of the fire barrier belt 5 is used to punch the self-tapping nail 7 to connect the fireproof plate and the embedded galvanized steel plate 4, which greatly improves the overall fixing performance and fireproof performance, and effectively overcomes the problem of difficult fixation of the pipe and the fire barrier ring caused by the hollow of the light steel keel wall.
