Description

Technical Field

[0001] The utility model relates to the technical field of deformation joint waterproof structures, in particular to a waterproof structure at the joint of a deformation joint between a concrete roof and a grid metal roof. Background Art

[0002] Between the concrete roof and the grid metal roof, cracks and water seepage problems are prone to occur due to the difference in deformation of the two materials under environmental factors such as temperature and humidity. Therefore, the waterproof structure at the junction of the deformation joints between the concrete roof and the grid metal roof is an important part of ensuring the overall waterproof performance of the building.

[0003] A deformation joint waterproof structure disclosed in the patent application with reference publication number CN219863418U is used to waterproof the deformation joint between two building foundation structures. Its cover plate includes a first covering part and two second covering parts. The two second covering parts are connected to the opposite sides of the first covering part. The first covering part can be extended and retracted as the two second covering parts approach or move away from each other. The first covering part corresponds to the deformation joint, and the two second covering parts are respectively fixed to the two building foundation structures, and are both bent into an "L" shape so as to be able to cling to the top surface of the building foundation structure and the side surface connected to the top surface. The support member is arranged corresponding to the deformation joint and elastically supported between the two building foundation structures and the first covering part. In the above deformation joint waterproof structure, the first covering part and the two second covering parts can cooperate to change their shape as the width of the deformation joint changes, so as to achieve a better waterproof effect. The support member can support the first covering part and at the same time prevent rainwater from entering the deformation joint to improve the waterproof effect.

[0004] As shown in the above-mentioned prior art, the existing expansion joint waterproof structure prevents rainwater from entering the expansion joint by setting a cover plate on the expansion joint, and the prior art adopts a locking member that penetrates from the outer wall of the waterproof layer into the expansion joint, so as to fix the cover body, the waterproof layer and the building foundation structure. However, such a setting easily causes the locking member to be corroded by rainwater, causing rainwater to enter the expansion joint along the through hole, and the waterproof effect is difficult to guarantee.

[0005] Therefore, it is necessary to provide a waterproof structure at the joint of the concrete roof and the grid metal roof deformation joint to solve the above technical problems. Utility Model Content

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] The utility model provides two technical solutions:

[0032] Figure 1 to Figure 2 The first embodiment is shown: the waterproof structure at the joint between the concrete roof and the grid metal roof deformation joint includes:

[0033] A grid metal layer 1, a concrete layer 2 is laid on the grid metal layer 1, and the grid metal layer 1 and the concrete layer 2 together form a building base;

[0034] Deformation joint 3, opened in the middle of the building base;

[0035] A waterproof layer 4 is laid on top of the concrete layer 2;

[0036] The waterproof cover 5 is installed above the deformation joint 3 and is located on the outer layer of the waterproof layer 4. A guide protrusion 16 is formed in the middle of the waterproof cover 5;

[0037] The telescopic connection assembly is installed on the top of the deformation joint 3 and is used to connect the building bases on both sides;

[0038] The elastic support member 6 is located above the telescopic connection assembly and has its outer wall pressed against two sides of the inner wall of the telescopic connection assembly, so as to support the guide protrusion 16 .

[0039] The telescopic connection assembly includes two brackets 7 mounted on the top of the deformation joint 3, wherein a casing 8 is fixed to the bottom of one bracket 7, and a slide plate 9 is fixed to the bottom of the other bracket 7, and one end of the slide plate 9 close to the casing 8 is slidably connected to the inner wall of the casing 8.

[0040] A groove 10 is formed above the bracket 7 , a threaded hole is formed on the inner wall of the groove 10 , and a bolt 11 for fixing the bracket 7 to the concrete layer 2 is threadedly connected in the threaded hole.

[0041] This application sets up a telescopic connection component, so that when the elastic support member 6 becomes fatigued while supporting the guide protrusion 16, the telescopic connection component can support the elastic support member 6, and because the telescopic connection component can be automatically fine-tuned as the size of the deformation joint 3 changes, it prevents the elastic support member 6 from falling into the deformation joint 3 and affecting the waterproof effect of the deformation joint 3.

[0042] Figures 1 to 3 A second embodiment is shown, which mainly differs from the first embodiment in that the waterproof cover 5 is made of elastic material, and a symmetrically arched structure is formed on the waterproof cover 5, an arc clamping strip 12 is symmetrically formed on the inner wall below, and a clamping groove 13 is symmetrically opened on the outer wall of the grid metal layer 1, and the arc clamping strip 12 is clamped with the inner wall of the clamping groove 13.

[0043] Drainage plates 14 are formed at the lower ends of both sides of the waterproof cover 5 , and a waterproof rubber strip 15 is used to form a seal between the drainage plate 14 and the waterproof layer 4 on one side close to the waterproof layer 4 .

[0044] This application sets a card slot 13 and an arc card strip 12, so that by applying a slight force downward on the waterproof cover 5, the waterproof cover 5 will be deformed to a certain extent, so that the arc card strip 12 slides on the outer wall of the waterproof layer 4 until it is stuck in the card slot 13, and the waterproof cover 5 can be quickly fixed on the deformation joint 3. The operation is simple and the deformation joint 3 can be effectively waterproofed. The setting of the arc card strip 12 reduces the friction force generated by pressing down the waterproof cover 5.

[0045] Working principle:

[0046] Two brackets 7 are erected above the deformation joint 3, and the brackets 7 are fixed above the concrete layer 2 using bolts 11 penetrating the threaded holes. The tops of the bolts 11 enter the grooves 10, so as not to hinder the laying of the waterproof layer 4; the slide plate 9 can slide on the inner wall of the casing 8 to change the spacing between the two brackets 7, which can adapt to the deformation of the deformation joint 3; the diversion protrusion 16 is used to reduce the accumulation of rainwater above the waterproof joint, and the elastic support member 6 plays a role in supporting the diversion protrusion 16, and the two sides of the elastic support frame are tightly against the bracket 7 to further prevent rainwater from entering. The waterproof strip 15 is used to prevent rainwater from rising to the drainage plate 14 when the drainage system collapses, causing rainwater to penetrate into the waterproof cover 5; the curved setting on the waterproof cover 5 is used to offset the deformation of the waterproof cover 5 caused by external influences, ensuring that the waterproof cover 5 is stably placed above the deformation joint 3; the setting of the arc clamping strip 12 and the clamping groove 13 can facilitate the rapid installation of the waterproof cover 5, press the waterproof cover 5 above the deformation joint 3, move the arc clamping strip 12 down to the clamping groove 13 and clamp it into the clamping groove 13, and the arc setting reduces the friction of the downward movement.
