Description

Technical Field

[0001] This utility model relates to the field of wall structure technology, specifically a fireproof and waterproof composite wall structure for underground spaces. Background Technology

[0002] Underground space refers to spaces or building structures located below ground level.

[0003] However, existing underground space walls have the following drawbacks:

[0004] (1) The existing underground space walls lack good fireproof and waterproof structures. When a fire or flood occurs in the underground space, they cannot effectively block the fire and water penetration, which will lead to damage to the facilities and equipment in the underground space.

[0005] (2) The existing underground space walls lack a good buffer structure. Since the underground space is often narrow, vehicles, carts and other transportation tools are prone to collide with the walls when moving, causing damage and cracking of the walls. Utility Model Content

[0006] The purpose of this utility model is to provide a fireproof and waterproof composite wall structure for underground spaces, in order to solve the problem mentioned in the background art that existing underground space walls lack a good fireproof and waterproof structure. When a fire or flood occurs in the underground space, they cannot effectively block the fire and water penetration, which will lead to damage to the facilities and equipment in the underground space. The underground space walls also lack a good buffer structure. Since underground spaces are often narrow, vehicles, trolleys and other transportation tools are prone to collisions with the walls when moving, causing damage and cracking to the walls.

[0007] To achieve the above objectives, this utility model provides the following technical solution: a fireproof and waterproof composite wall structure for underground spaces, comprising a base layer, a waterproof layer fixedly connected to the outer wall of the base layer, a heat insulation layer fixedly connected to the outer wall of the waterproof layer, a fire-resistant layer fixedly connected to the outer wall of the heat insulation layer, a corrosion-resistant layer fixedly connected to the outer wall of the fire-resistant layer, a buffer layer fixedly connected to the inner wall of the base layer, a plurality of buffer cavities evenly distributed inside the buffer layer, a mounting base fixedly connected to one side of the inner wall of the buffer cavity, a connector fixedly connected to the middle of one side of the inner wall of the mounting base, a damper fixedly installed on the inner wall of the connector, a connecting plate fixedly connected to one end of the damper, and the connecting plate fixedly connected to the other side of the inner wall of the buffer cavity, and sliding rods fixedly connected to all four sides of the connector.

[0008] When using a fireproof and waterproof composite wall structure for underground spaces according to this technical solution, the fireproof and waterproof structure can provide better protection for facilities and equipment in the underground space, and the buffer structure can reduce the impact and damage to the wall from collisions with transportation vehicles.

[0009] In a preferred embodiment of this invention, a sliding sleeve is slidably fitted onto the middle of the sliding rod surface, and a connecting rod is rotatably connected to the surface of the sliding sleeve. One end of the connecting rod is rotatably connected to a connecting plate, and a buffer spring is fitted onto one side of the sliding rod surface. The connecting rod serves a transmission function.

[0010] In a preferred embodiment of this invention, one end of each of the four sliding rods is fixedly connected to one of the four sides of the inner wall of the mounting base. The sliding sleeve can slide and move on the surface of the sliding rods.

[0011] In a preferred embodiment of this invention, one end of the buffer spring is fixedly connected to the sliding sleeve, and the other end of the buffer spring is fixedly connected to the inner wall of the mounting base. Fixing both ends of the buffer spring prevents it from shifting or falling off the sliding rod.

[0012] In a preferred embodiment of this invention, the waterproof layer has a plurality of recesses evenly distributed on the side near the insulation layer, and the insulation layer has a plurality of protrusions evenly distributed on the side near the waterproof layer. The protrusions and recesses increase the contact area between the layers, resulting in a more secure connection.

[0013] In a preferred embodiment of this invention, the base layer is uniformly and fixedly connected with several transverse reinforcing bars. These transverse reinforcing bars ensure the structural strength of the wall.

[0014] In a preferred embodiment of this invention, several vertical reinforcing bars are fixedly connected to the surfaces of the horizontal reinforcing bars. These vertical reinforcing bars further enhance the strength of the wall.

[0015] As a preferred embodiment of this invention, the surface of the buffer layer is coated with an anti-fouling coating. This anti-fouling coating makes it difficult for dirt to adhere to the wall surface.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] 1. The walls of the underground space are equipped with a waterproof layer to prevent the infiltration of groundwater. The fire-resistant layer and the heat insulation layer can prevent the spread of fire and reduce heat conduction, thus providing better protection for the facilities and equipment in the underground space and enhancing safety. The corrosion-resistant layer can prevent the walls from being corroded by corrosive substances in water and improve their service life.

[0018] 2. By installing a buffer layer on the walls of the underground space, when it is accidentally hit by a vehicle, the buffer layer and the internal dampers and buffer springs can play a better role in buffering and protecting against the impact, reducing the impact and damage to the walls.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4 This utility model provides a fireproof and waterproof composite wall structure for underground spaces, including a base layer 1. A waterproof layer 2 is fixedly connected to the outer wall of the base layer 1. A heat insulation layer 3 is fixedly connected to the outer wall of the waterproof layer 2. A fire-resistant layer 4 is fixedly connected to the outer wall of the heat insulation layer 3. A corrosion-resistant layer 5 is fixedly connected to the outer wall of the fire-resistant layer 4 to improve the protection effect. A buffer layer 6 is fixedly connected to the inner wall of the base layer 1. Several buffer cavities 8 are evenly opened inside the buffer layer 6. A mounting base 9 is fixedly connected to one side of the inner wall of the buffer cavity 8. A connector 10 is fixedly connected to the middle of one side of the inner wall of the mounting base 9. A damper 11 is fixedly installed on the inner wall of the connector 10. A connecting plate 12 is fixedly connected to one end of the damper 11 and the connecting plate 12 is fixedly connected to the other side of the inner wall of the buffer cavity 8 to provide buffering performance. Sliding rods 13 are fixedly connected to all four sides of the connector 10.

[0026] During use, the underground space is equipped with a waterproof layer 2 in the walls to prevent the infiltration of groundwater. The fire-resistant layer 4 and the heat insulation layer 3 can prevent the spread of fire and reduce heat conduction, thus providing better protection for the facilities and equipment in the underground space and enhancing safety. The corrosion-resistant layer 5 can prevent the walls from being corroded by corrosive substances in water and improve their service life.

[0027] A sliding sleeve 14 is slidably sleeved on the middle of the surface of the sliding rod 13. A connecting rod 16 is rotatably connected to the surface of the sliding sleeve 14, and one end of the connecting rod 16 is rotatably connected to the connecting plate 12 for transmission. A buffer spring 15 is sleeved on one side of the surface of the sliding rod 13. One end of the four sliding rods 13 is fixedly connected to the four sides of the inner wall of the mounting base 9, respectively. One end of the buffer spring 15 is fixedly connected to the sliding sleeve 14, and the other end of the buffer spring 15 is fixedly connected to the inner wall of the mounting base 9 to prevent it from falling off.

[0028] In use, a buffer layer 6 is installed on the wall of the underground space. When it is accidentally hit by a transportation vehicle, the buffer layer 6 and the internal damper 11 can buffer and protect against the impact. When the connecting plate 12 is moved by the impact, it will drive the sliding sleeve 14 to move through the connecting rod 16, which will compress the buffer spring 15. Under the elastic force of the buffer spring 15, the buffer performance can be further improved, reducing the impact and damage to the wall.

[0029] The waterproof layer 2 has several recesses 20 evenly distributed on the side near the heat insulation layer 3, and the heat insulation layer 3 has several protrusions 7 evenly distributed on the side near the waterproof layer 2, increasing the contact area. The base layer 1 has several horizontal steel bars 17 evenly fixedly connected inside, and several vertical steel bars 18 are fixedly connected to the surface of the horizontal steel bars 17, improving the structural strength. The surface of the buffer layer 6 is coated with an anti-fouling coating 19 to improve the anti-fouling performance.

[0030] In use, by setting up interlaced horizontal steel bars 17 and vertical steel bars 18, the structural strength of the underground space wall can be improved, and it is not easy to crack or be damaged. The fluorocarbon anti-fouling coating 19 set on the inner surface of the wall can prevent dirt from sticking to the wall surface and is easy to clean. The set protrusions 7 and concave parts 20 make the connection between the waterproof layer 2 and the heat insulation layer 3 more firm and not easy to fall off.

[0031] In practical use, this utility model provides a fireproof and waterproof composite wall structure for underground spaces. The underground space walls are equipped with a polyethylene waterproof layer 2 to prevent groundwater penetration. A fire-resistant brick fire-retardant layer 4 and a rock wool insulation layer 3 prevent the spread of fire and reduce heat conduction, thus providing better protection for facilities and equipment within the underground space and enhancing safety. An epoxy resin corrosion-resistant layer 5 prevents the walls from being corroded by water, increasing their service life. A rubber buffer layer 6 is installed on the underground space walls. When the walls are accidentally struck by a transport vehicle, the buffer layer 6 and its internal damper 11 provide cushioning protection against the impact. Furthermore, when the connecting plate 12 is moved by the impact, it moves the sliding sleeve 14 via the connecting rod 16, which in turn compresses the buffer spring 15. Under the elastic force of the buffer spring 15, the cushioning performance is further improved, reducing the impact and damage to the walls.

[0032] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
