Description

Technical Field

[0001] The utility model relates to the technical field of expansion joint construction, in particular to a expansion joint construction structure at a corner. 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.

[0003] For example, a Chinese patent (publication number: CN217027546U) discloses a deformation joint waterproof construction structure, which relates to the field of building structure technology, and improves the problems of existing deformation joints with simple structure, poor waterproof effect, and easy water leakage. It includes a deformation joint and a buffer sealing assembly, and the buffer sealing assembly includes a support plate, a spring, a sealing block, a sealing sleeve and a first waterstop. The inner wall of the deformation joint is provided with a sealing groove adapted to the sealing block, and the top of the deformation joint is provided with a groove. The interior of the groove is provided with a second waterstop, a waterproof board and a waterproof filling layer, and the top of the groove is provided with a cover plate. The utility model can improve the waterproof effect of the deformation joint by setting the waterproof board and the waterproof filling layer, and can reduce the water entering the deformation joint. Through the setting of the buffer sealing assembly, when water seepage occurs on the inner wall of the deformation joint, the sealing sleeve will expand after encountering water, so that the sealing block is tightly combined with the sealing groove, thereby reducing water infiltration.

[0004] The above-mentioned expansion joint waterproof construction structure still has certain shortcomings. When the expansion joint is deformed, the spring can play a shock-absorbing and buffering role. When water seepage occurs on the inner wall of the expansion joint, the water will flow into the sealing groove along the inner wall of the expansion joint. The sealing sleeve will expand after encountering water, but the spring has limited limiting effect on the sealing block. During the vibration of the spring, there will be a certain gap between the sealing block and the wall, resulting in poor sealing effect and easy water seepage. Therefore, a corner expansion joint construction structure is proposed to solve the above problems. Utility Model Content

DETAILED DESCRIPTION

[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0024] See also Figure 1-2 In this embodiment, a corner deformation joint construction structure includes a wall 1 and a crack 5 opened on the upper surface of the wall 1. The crack 5 is L-shaped.

[0025] See also Figure 1 、 Figure 3 and Figure 4In order to improve the sealing performance, the sealing mechanism 2 in this embodiment includes a fixing component and a protection component. The fixing component includes a fixing block 201 placed on the upper surface of the wall 1, and the shell 3 is fixed to the lower surface of the fixing block 201. The fixing component also includes a threaded rod 202 rotatably connected to the lower surface of the inner cavity of the shell 3 through a bearing seat. The outer surface of the threaded rod 202 is threadedly connected to two moving blocks 203. The fixing component also includes push blocks 204 fixed to the left and right sides of the inner cavity of the shell 3. The moving block 203 and the push block 204 are both trapezoidal, and the moving block 203 abuts against the push block 204.

[0026] The protective component includes a protective plate 206 attached to the upper surface of the fixed block 201. The upper surface of the protective plate 206 and the lower surface of the inner cavity of the fixed block 201 are both provided with multiple through holes 207. The upper surface of the fixed block 201 and the upper surface of the wall 1 are both provided with multiple threaded holes 205. The internal threads of the threaded holes 205 are connected with bolts 208.

[0027] Among them, the thread of the threaded rod 202 is divided into two sections, and the two sections of thread are in opposite directions. The threaded rod 202 drives the two moving blocks 203 to move relative to each other at the same time, so that the moving block 203 squeezes the push block 204, so that the shell 3 and the crack 5 are in closer contact. A rotating handle is fixed on the upper surface of the threaded rod 202 to facilitate the rotation of the threaded rod 202. Two vertical rods are fixed on the lower surface of the inner cavity of the shell 3. The moving block 203 is slidably connected to the outer surface of the vertical rod to increase the stability of the moving block 203 when moving.

[0028] In addition, a circular hole is opened on the upper surface of the inner cavity of the fixed block 201, and the threaded rod 202 is rotatably connected to the inside of the circular hole through a bearing, thereby increasing the stability of the threaded rod 202 during rotation. The bolt 208 is T-shaped, and the bolt 208 is slidably connected to the inside of the through hole 207. The wall 1 and the fixed block 201 are fixed by the lower end bolt 208, and the fixed block 201 and the protective plate 206 are fixed by the upper end bolt 208.

[0029] The sealing mechanism 2 in this embodiment places the fixed block 201 on the wall 1, inserts the shell 3 into the crack 5, fixes the fixed block 201 through the lower end bolt 208 and the lower end threaded hole 205, rotates the rotary handle to drive the threaded rod 202 to rotate, and causes the two movable blocks 203 to move relative to each other at the same time. The movable block 203 squeezes the push block 204, so that the shell 3 and the crack 5 are tightly connected to improve the sealing effect, and the protective plate 206 is placed on the fixed block 201, and is threadedly connected to the upper end threaded hole 205 through the upper end bolt 208 to fix the protective plate 206, thereby improving the sealing effect on the crack 5.

[0030] See also Figure 4In order to improve the sealing performance, the protective mechanism 4 in this embodiment includes a moisture-proof layer 401 fixed to the outer surface of the shell 3, a fire-proof layer 402 is fixed to the outer surface of the moisture-proof layer 401, a waterproof layer 403 is fixed to the outer surface of the fire-proof layer 402, and an expansion layer 404 is fixed to the outer surface of the waterproof layer 403.

[0031] Among them, the moisture-proof layer 401 is a polyethylene film, which has excellent anti-corrosion performance, electrical performance, moisture-proof performance, anti-leakage performance, and high tensile strength. The fire-proof layer 402 is acrylic fiber, a material made of acrylic fiber with the characteristics of fire resistance, wear resistance, waterproofness, high temperature resistance, etc., which is convenient, flexible, easy to process, and has excellent protective performance. The waterproof layer 403 is an acrylic emulsion, which has good aging resistance, extensibility, elasticity, adhesion and film-forming properties, and good waterproof performance. The expansion layer 404 is a water-swelling rubber, which is a water-swelling waterproof rubber made of water-absorbing materials such as water-soluble polyurethane prepolymers and sodium acrylate polymer water-absorbing resins and synthetic rubbers such as natural rubber and chloroprene rubber, which reduces the gap between the crack 5 and improves the sealing performance.

[0032] The protective mechanism 4 in this embodiment is composed of a moisture-proof layer 401, a fire-proof layer 402, a waterproof layer 403 and an expansion layer 404, which reduces the gap between the protective mechanism 4 and the crack 5 and improves the sealing performance.

[0033] The working principle of the above embodiment is:

[0034] (1) After placing the fixed block 201 on the upper surface of the wall 1, the shell 3 is inserted into the crack 5 and connected to the lower threaded hole 205 through the lower end bolt 208 to fix the fixed block 201. Turn the rotating handle to drive the threaded rod 202 to rotate. Since the two sections of the threaded rod 202 have opposite thread directions, the threaded rod 202 will drive the two moving blocks 203 to move relative to each other at the same time. The moving block 203 will abut against the push block 204. The push block 204 is squeezed by the moving block 203, so that the shell 3 is tightly connected to the crack 5, thereby improving the sealing effect. Finally, the protective plate 206 is placed on the fixed block 201 and is threadedly connected to the upper end threaded hole 205 through the upper end bolt 208 to fix the protective plate 206, thereby improving the sealing effect on the crack 5.

[0035] (2) The protective mechanism 4 is composed of a moisture-proof layer 401, a fire-proof layer 402, a waterproof layer 403 and an expansion layer 404. The moisture-proof layer 401 is a polyethylene film, which has excellent corrosion resistance, electrical properties, moisture-proof properties, anti-leakage properties and high tensile strength. The fire-proof layer 402 is acrylic fiber, which has the characteristics of fire resistance, wear resistance, waterproofness and high temperature resistance. The waterproof layer 403 is an acrylic emulsion, which has good aging resistance, elongation, elasticity, adhesion and film-forming properties, and good waterproof performance. The expansion layer 404 is a water-swelling rubber, which is made of water-absorbing materials such as water-soluble polyurethane prepolymer and sodium acrylate high molecular water-absorbing resin and synthetic rubber such as natural rubber and chloroprene rubber. It reduces the gap between the crack 5 and improves the sealing performance.
