Description

Technical Field

[0001] The present application relates to the technical field of basement structures, and in particular to a basement roof deformation joint structure. Background Art

[0002] Deformation joints are a general term for expansion joints, settlement joints, and seismic joints. Buildings often deform under the influence of external factors, leading to cracks or even damage. Deformation joints are structural joints reserved for this situation. If deformation joints are not set in an extra-long basement, temperature stress can easily cause cracks in the basement roof, so deformation joints need to be set at a certain interval. In the prior art, some basements will fill in the deformation joints with filling layers to transfer force and absorb water. However, these filling layers sandwiched in the deformation joints are easy to fall off, resulting in unstable structures, and blocking the bottom of the deformation joints can easily affect the normal use of the deformation joints. Utility Model Content

[0003] Based on this, it is necessary to provide a basement roof deformation joint structure to solve the technical problem of unstable basement roof deformation joint structure in the prior art.

[0004] To achieve the above-mentioned purpose, the present application provides a basement roof deformation joint structure, the basement roof deformation joint structure comprising:

[0005] First top plate;

[0006] A second top plate is arranged with a horizontal spacing from the first top plate to form a deformation joint;

[0007] A cantilever plate, one end of which is connected to the bottom surface of the first top plate, and the other end of which extends below the second top plate so that the second top plate can be overlapped on the cantilever plate;

[0008] A filling layer is arranged in the deformation joint; and

[0009] The waterproof layer covers the top of the first top plate, the second top plate and the expansion joint.

[0010] Optionally, the first top plate and the cantilever plate are of an integrated structure.

[0017] Optionally, the filling layer consists of graded sand and gravel.

[0018] Optionally, multiple layers of waterproof layer are provided at the deformation joint.

[0019] The beneficial effect of the basement roof deformation joint structure provided by the present application is that: compared with the prior art, the basement roof deformation joint structure of the present application includes a first roof, a second roof, a cantilevered plate, a filling layer and a waterproof layer. The first roof and the second roof form a deformation joint, and the filling layer is arranged in the deformation joint. The filling layer can ensure that each roof can also transmit horizontal force under the action of earthquake force and strong wind. One end of the cantilevered plate is connected to the bottom surface of the first roof, and the other end of the cantilevered plate extends to the bottom of the second roof.

[0030] The embodiment of the present application provides a basement roof deformation joint structure, please refer to Figure 1 The basement roof deformation joint structure includes a first roof 1, a second roof 2, a cantilevered plate 4, a filling layer 5 and a waterproof layer 6. The second roof 2 and the first roof 1 are arranged at a distance in the horizontal direction to form a deformation joint 3; one end of the cantilevered plate 4 is connected to the bottom surface of the first roof 1, and the other end of the cantilevered plate 4 extends to the bottom of the second roof 2 so that the second roof 2 can be overlapped on the cantilevered plate 4; the filling layer 5 is arranged in the deformation joint 3; the waterproof layer 6 covers the first roof 1, the second roof 2 and the top of the deformation joint 3.

[0031] In the embodiment of the present application, the deformation joint structure of the basement roof includes a first roof 1, a second roof 2, a cantilever plate 4, a filling layer 5 and a waterproof layer 6. The first roof 1 and the second roof 2 form a deformation joint 3. The filling layer 5 is arranged in the deformation joint 3. The filling layer can ensure that each roof can transmit horizontal force under the action of earthquake force and strong wind. One end of the cantilever plate 4 is connected to the bottom surface of the first roof 1, and the other end of the cantilever plate 4 extends to the bottom of the second roof 2. The cantilever plate 4 can be overlapped by the second roof 2, and the second roof 2 can move freely to ensure the normal use of the deformation joint 3. The cantilever plate 4 can also carry the filling layer 5 to prevent the filling layer 5 from falling from the deformation joint 3, thereby improving the stability of the deformation joint structure of the basement roof.

[0032] On the other hand, the top plates of the basement top plate deformation joint structure of the present application are completely disconnected from each other, which can avoid cracking caused by temperature stress.

[0033] On the other hand, the waterproof layer 6 of the basement roof deformation joint structure of the present application is arranged at the top, and the waterproof layer 6 and the filling layer 5 in the deformation joint 3 are easy to replace.

[0034] In one embodiment, see Figure 1 The first top plate 1 and the cantilever plate 4 are in an integrated structure, which is easy to produce and has a stable structure.

[0035] In another embodiment, see Figure 1A first boss portion 110 is provided at the top of the first top plate 1 close to one end of the deformation joint 3 , and a second boss portion 210 is provided at the top of the second top plate 2 close to one end of the deformation joint 3 .

[0036] In this way, the first boss portion 110 protrudes relative to other areas of the first top plate 1 , and the second boss portion 210 protrudes relative to other areas of the second top plate 2 , so that water is not easily accumulated at the deformation joint 3 , thereby reducing the possibility of water seepage at the deformation joint 3 .

[0037] In a specific embodiment, see Figure 1 The first boss portion 110 and the second boss portion 210 are both provided with a slope on one side away from the deformation joint 3 to facilitate the liquid to flow down and reduce the possibility of water accumulation in the first boss portion 110 and the second boss portion 210 .

[0038] In other embodiments, a drainage groove is provided at the cantilever plate 4 directly below the deformation joint 3. Once water accumulates in the deformation joint 3, the drainage groove can promptly discharge the liquid from the outlet of the drainage groove to prevent the liquid from dripping into the basement along various parts of the cantilever plate 4.

[0039] In another embodiment, see Figure 1 A first column 8 is provided at the bottom of the first top plate 1 near one end of the deformation joint 3, and a second column 9 is provided at the top of the second top plate 2 near one end of the deformation joint 3, so as to better support the ends of each top plate and improve the structural stability.

[0040] In a specific embodiment, the distance between the first column 8 and the second column 9 is 2m-3m. It is understandable that the distance between the first column 8 and the second column 9 is selected according to actual needs and is not limited here.

[0041] Exemplarily, the length of the basement of the present application exceeds 200 m, and the distance between the first column 8 and the second column 9 is 2.5 m.

[0042] In another embodiment, see Figure 1 A wear-resistant plate 7 is sandwiched between the second top plate 2 and the cantilever plate 4 to reduce the difficulty of the second top plate 2 sliding on the cantilever plate 4.

[0043] In a specific embodiment, the wear-resistant plate 7 is a polytetrafluoroethylene plate, which has excellent properties such as high and low temperature resistance, corrosion resistance, weather resistance, high insulation, high lubricity, non-adhesion, and non-toxicity.

[0044] In another embodiment, the filling layer 5 is composed of graded sand and gravel, which can ensure that each top plate can better transmit horizontal force under the action of earthquake force and strong wind.

[0045] In another embodiment, see Figure 1The waterproof layer 6 at the deformation joint 3 is provided with multiple layers, which further improves the waterproof ability of the deformation joint 3.

[0046] The technical features of the above-described embodiments may be arbitrarily combined. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0047] The above-described embodiments only express several implementation methods of the present application, and the descriptions thereof are relatively specific and detailed, but they cannot be construed as limiting the scope of the patent application. It should be pointed out that, for a person of ordinary skill in the art, several variations and improvements can be made without departing from the concept of the present application, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent application shall be subject to the attached claims.
