Description
Technical Field
[0001] The utility model relates to the technical field of construction engineering construction, and more specifically, the utility model relates to a curtain wall cross-deformation joint node structure. Background Art
[0002] At present, the general structure of a conventional commercial and office complex is generally a podium plus a main building, and a structural deformation joint is required in the middle to reduce the deformation influence caused by earthquakes between high and low buildings. If the curtain wall side line of the tower is far from the tower and crosses the deformation joint, the lower section of the curtain wall structural keel needs to be retracted and fixed to the tower structure. In the form of high and low spans, the traditional installation method is to directly place the curtain wall at the deformation joint, which may lead to uneven settlement of the high and low spans, posing a risk of cracking and long-term failure of waterproofing, with potential water leakage hazards. Therefore, we propose a curtain wall cross-deformation joint node structure to solve the above-mentioned problems. Content of the Utility Model

The first cantilever is arranged on the outdoor roof of the low-span building and on one side of the deformation joint, and the second cantilever is arranged on the outdoor roof of the high-span building and on the other side of the deformation joint;

[0009] As a preferred technical solution of the utility model, the heat preservation strip is made of foamed polyethylene material, and the connections between the heat preservation strip and the first cantilever and the second cantilever are both adhesively connected.
[0010] As a preferred technical solution of the utility model, a deformation joint cover plate for covering the opening of the lateral joint is fixedly installed outside the first cantilever and the second cantilever.
[0011] As a preferred technical solution of the present utility model, the curtain wall keel and the embedded part are fixedly connected by welding.

[0014] In the present utility model, a lateral joint is formed by the cooperation of the first cantilever and the second cantilever with an inverted "L" structure in the deformation joint node area.

[0018] In order to solve the problems of uneven settlement, cracking and water leakage during the installation of the curtain wall at the deformation joint between high and low spans, the present utility model provides a curtain wall cross-deformation joint node structure, which not only solves the problem of fixing the curtain wall across the deformation joint, but also reduces the risks of settlement and cracking, and also reduces the hidden danger of water leakage in the deformation joint. The following further describes the curtain wall cross-deformation joint node structure with specific embodiments in combination with the drawings.
[0019] As Figure 1 shown, the present utility model provides a curtain wall cross-deformation joint node structure, including the outdoor roof 1 of the low-span building, the outdoor roof 2 of the high-span building, the first cantilever 11 and the second cantilever 21. The first cantilever 11 is arranged on the outdoor roof 1 of the low-span building and is located on one side of the deformation joint, and the second cantilever 21 is arranged on the outdoor roof 2 of the high-span building and is located on the other side of the deformation joint;
[0020] The first cantilever 11 as a whole adopts an inverted "L" structure, and it combines with the second cantilever 21 to form a lateral joint 6 for connecting the deformation joint;
[0021] Inside the side seam 6, there is a heat preservation strip 4 connected to both the first cantilever 11 and the second cantilever 21.
[0022] At the upper end of the first cantilever 11, there is a pre-embedded groove 111, and inside the pre-embedded groove 111, there is a pre-embedded part 112 for installing the curtain wall keel 3.
[0023] Among them, both the first cantilever 11 and the second cantilever 21 are made of concrete materials as a whole;
[0024] By making the first cantilever 11 and the second cantilever 21 of concrete materials, it is beneficial for workers to build them together when constructing the building tower, without subsequent installation, ensuring the stability of the overall connection.
[0025] Among them, the heat preservation strip 4 is made of foamed polyethylene material, and the connections between the heat preservation strip 4 and the first cantilever 11 and the second cantilever 21 are all connected by glue;
[0026] By using the heat preservation strip 4 made of the new environmentally friendly material foamed polyethylene with heat preservation and moisture-proof capabilities, the opening area of the side seam 6 can be effectively blocked, thereby avoiding water leakage at the deformation joint and achieving a better waterproof effect.
[0027] Among them, on the outside of the first cantilever 11 and the second cantilever 21, there is a deformation joint cover plate 5 fixedly installed to cover the opening of the side seam 6;
[0028] By fixedly connecting the upper end of the deformation joint cover plate 5 to the first cantilever 11 and the lower end of the deformation joint cover plate 5 to the second cantilever 21, the opening of the side seam 6 formed by the combination of the first cantilever 11 and the second cantilever 21 can be covered, thereby achieving a sealing and protective effect and further improving the waterproof effect of the deformation joint.
[0029] Among them, the curtain wall keel 3 and the pre-embedded part 112 are fixedly connected by welding;
[0030] By welding and fixing between the curtain wall keel 3 and the pre-embedded part 112, the installation and fixation of the curtain wall are ensured, and through the upward supporting force of the pre-embedded part 112, the risks of curtain wall settlement and cracking can be reduced.
[0031] Among them, both the first cantilever 11 and the second cantilever 21 are respectively fixed on the outdoor roof 1 of the low-span house and the outdoor roof 2 of the high-span house in the form of pouring;
[0032] By respectively forming the first cantilever member 11 and the second cantilever member 21 on the outdoor roof 1 of the low-span building and the outdoor roof 2 of the high-span building by means of casting, it is beneficial to the preliminary construction of workers, and it is beneficial for the outdoor roof 1 of the low-span building and the first cantilever member 11, and the outdoor roof 2 of the high-span building and the second cantilever member 21 to form a whole respectively, ensuring the stability of the connection.
[0033] The working principle and usage process of the present utility model:
[0034] By arranging the first cantilever member 11 with an inverted "L" structure in the deformation joint node area to cooperate with the second cantilever member 21 to form a lateral joint 6, the existence of the lateral joint 6 can change the orientation of the traditional deformation joint, changing the upward type to the lateral type, so that rainwater will not directly enter the deformation joint when falling. Then, through the blocking and covering of the thermal insulation strip 4 and the deformation joint cover plate 5, the possibility of rainwater entering the deformation joint from the lateral joint 6 is also eliminated, effectively reducing the potential leakage hazard of the deformation joint.
[0035] By arranging embedded parts 112 on the first cantilever member 11 for welding with the bottom structure of the installed curtain wall keel 3, it is beneficial to the fixation of the curtain wall keel 3. At the same time, through the support of the embedded parts 112, a certain upward support force can be provided for the curtain wall, solving the problem of fixing the curtain wall across the deformation joint, and reducing the risks of settlement and cracking at the same time.
