Description

Technical Field

[0001] This application relates to the field of waterproofing technology for expansion joints, and more particularly to a waterproofing structure for expansion joints in side panels. Background Technology

[0002] Expansion joints are a general term for expansion joints, settlement joints, and seismic joints. Buildings often crack or even break under the influence of external factors, and expansion joints are structural joints reserved to address this situation.

[0003] Expansion joints are often set in the side panels. The waterproof structure of the expansion joint is higher than that of the side panel. In related technologies, the construction of the waterproof structure first requires filling the expansion joint with sealant, then laying a synthetic polymer roll on the expansion joint, with the synthetic polymer roll recessed 2 cm at the expansion joint, then laying a foam strip at the recessed area, then laying another layer of polymer roll, and finally covering it with fine stone concrete or stainless steel cover plate.

[0004] Regarding the aforementioned technologies, when the expansion joint deforms, if fine aggregate concrete is used to cover it, the fine aggregate concrete is prone to breakage. If stainless steel cover plates are used to cover the expansion joint, the stainless steel is prone to collapse. Therefore, whether fine aggregate concrete or stainless steel cover plates are used, when the expansion joint deforms, it is easy to cause a decrease in the stability of the waterproof structure and damage to the waterproof structure.

[0005] Therefore, this application proposes a waterproof structure for the expansion joint of the side plate. Utility Model Content

[0006] This application proposes a waterproof structure for side plate expansion joints to solve the problems mentioned in the background art. A sealing material is placed in the top layer of concrete and on the upper layer of polystyrene foam, and polyurea grout is poured in. It can be firmly bonded to the concrete joint. No matter how the crack expands and deforms, it will not crack or fall off, thereby improving the waterproof performance of the expansion joint, ensuring the stability of the waterproof structure, and greatly improving the practicality of the device.

[0007] To achieve the above objectives, this application adopts the following technical solution:

[0008] A waterproof structure for a side panel expansion joint includes a side panel, an expansion joint, and a waterproof structure. The waterproof structure consists of a waterproof membrane and an isolation layer, a reinforcing layer, a bottom layer of concrete, an elastic block, a top layer of concrete, a lower layer of polystyrene foam, an embedded waterstop, an upper layer of polystyrene foam, and a sealing material. The waterproof membrane is laid on the expansion joint, the isolation layer is located on the waterproof membrane, and the reinforcing layer is located on the isolation layer.

[0009] In a preferred embodiment, a bottom layer of concrete is provided on the isolation layer, and the bottom layer of concrete is located on both sides of the reinforcing layer;

[0010] By adding an isolation layer and a reinforcing layer, the isolation and waterproofing effect is improved. A base layer of concrete is set on the isolation layer and the reinforcing layer, and the thickness of the concrete structure should not be less than 300mm, thereby improving the practicality of the device.

[0011] In a preferred embodiment, an elastic block is provided on the bottom concrete, and the elastic block is located above the reinforcing layer;

[0012] The practicality of the device is improved by setting elastic blocks on the bottom layer of concrete to prevent moisture from seeping into the expansion joints and by adding more concrete.

[0013] In a preferred embodiment, a top layer of concrete is provided on the bottom layer of concrete, and the top layer of concrete is located on both sides of the elastic block;

[0014] The practicality of the device is improved by setting a top layer of concrete on top of the bottom layer of concrete and on both sides of the elastic block.

[0015] In a preferred embodiment, an embedded waterstop is provided in the middle of the top concrete layer, and an upper layer of polystyrene foam and a lower layer of polystyrene foam are provided outside the embedded waterstop and in the middle of the top concrete layer.

[0016] By setting an embedded waterstop in the top layer of concrete, the embedded waterstop should be accurately positioned, and the central hollow ring should coincide with the center line of the expansion joint. Then, the top layer of concrete and the upper and lower sections of the embedded waterstop are filled with lower and upper layers of polystyrene foam, respectively, thereby improving the practicality of the device.

[0017] In a preferred embodiment, a sealing material is provided on top of the top concrete layer, and the sealing material is provided with polyurea grout for filling the joint between the top concrete layer and the sealing material;

[0018] By placing a sealing material in the top layer of concrete and on the upper layer of polystyrene foam, and simultaneously pouring polyurea grout between the sealing material and the top layer of concrete, it can firmly bond to the concrete joint, reducing the risk of the sealing material cracking and falling off when the crack expands and deforms. This improves the waterproof performance of the expansion joint, ensures the stability of the waterproof structure, and enhances the practicality of the device.

[0019] In a preferred embodiment, the bottom of the polyurea grout is provided with a heat insulation strip, and the top of the upper polystyrene foam is provided with a fire-resistant strip, and the fire-resistant strip and the heat insulation strip are connected to each other.

[0020] By adding fire-resistant strips, the fire can prevent the fire from spreading further during a fire. These strips can block the spread of smoke and flames, thus preventing the fire from spreading further and protecting people and property. By adding insulation strips, which have good waterproof properties, the fire can prevent water penetration and avoid corrosion of the side panels, thereby improving the practicality of the device.

[0021] The beneficial effects of this application are:

[0022] 1. This side plate expansion joint waterproof structure involves placing a sealing material in the top layer of concrete and on the upper layer of polystyrene foam, and then pouring polyurea grout. It can firmly bond to the concrete joint and will not crack or fall off no matter how the crack expands or deforms, thereby improving the waterproof performance of the expansion joint, ensuring the stability of the waterproof structure, and greatly enhancing the practicality of the device.

Then, the lower layer of polystyrene foam 9 and the upper layer of polystyrene foam 11 are filled in the top concrete 8 and the upper and lower sections of the embedded waterstop 10, respectively, thereby improving the practicality of the device.

[0034] A sealing material 12 is installed on the top concrete 8, and polyurea grout is poured between the sealing material 12 and the top concrete 8.
