Description

Technical Field

[0001] The utility model relates to the technical field of building structures, and in particular to an assembled shear wall vertical seam node connection structure. Background Art

[0002] With the continuous development of materials and structural design technology, shear walls are widely used in high-rise buildings and houses with high requirements for lateral resistance. However, there are usually vertical through-slits between adjacent prefabricated shear walls, which can easily lead to failure of the shear wall connection, thereby greatly reducing the stability of the structure. The existing technology mostly adopts the method of fixing horizontal stirrups to each other, by tying the vertical longitudinal reinforcements on both sides of the shear wall in situ and supporting the concrete formwork for pouring, but this method requires the use of a large number of casting formworks, and the tying of steel bars is cumbersome, which will increase the construction cost while consuming a lot of manpower and time, seriously affecting the construction progress.

[0003] After searching, the publication number CN113898092A, a prefabricated shear wall vertical joint structure and its construction method, discloses a prefabricated shear wall vertical joint structure and its construction method, which relates to the technical field of prefabricated concrete shear wall vertical joint connection structure in civil engineering. Its main structure includes: shear wall, embedded steel and connector; the embedded steel is partially embedded in the shear wall, and the embedded steel on the two shear walls are butt-jointed by tongue and groove, and the joint is covered with connectors.

[0004] The existing shear walls have the following problems:

[0005] The current shear wall requires complex prefabricated template construction and high-precision manufacturing requirements. It is inevitable that certain errors will occur during the production and assembly process, which makes it difficult to assemble the plug-in fixing parts. Trimming is required to complete the assembly of the shear wall. At the same time, this solution also has the problem of high steel consumption. Considering the huge amount of shear walls used in general high-rise buildings, this will increase the construction cost. Therefore, the widespread promotion and use of this solution in the construction industry still faces certain difficulties.

[0006] In view of the above problems, we propose a prefabricated shear wall vertical seam node connection structure. Utility Model Content

[0007] The utility model provides an assembled shear wall vertical seam node connection structure, which solves the problems raised by an assembled shear wall vertical seam node connection structure in the related art.

[0008] The technical solution of the utility model is as follows:

[0010] Preferably, the first embedded parts are fixedly connected to the shear wall reinforcement skeleton via hooks, and the first embedded parts are engaged with each other.

[0011] Preferably, a plurality of second embedded parts are provided on both sides of the second prefabricated shear wall, the side of the second embedded part away from the shear wall steel frame is a straight plate, mounting screw holes are provided on the upper and lower sides inside the second embedded part, mounting bolts are passed through the inside of the two second embedded parts, and a bent hook is provided on the side of the second embedded part close to the shear wall steel frame.

[0027] The following will be combined with 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 of 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.

[0028] Example 1

[0029] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 6 and Figure 7As shown, this embodiment proposes an assembled shear wall vertical seam node connection structure, including a first prefabricated shear wall 1, a second prefabricated shear wall 2, a first embedded part 4 and a second embedded part 5. A shear wall steel frame 3 is arranged inside the first prefabricated shear wall 1, and a shear wall steel frame 3 is arranged inside the second prefabricated shear wall 2. Several first embedded parts 4 are arranged on both sides of the first prefabricated shear wall 1. The side of the first embedded part 4 away from the shear wall steel frame 3 is an asymmetric "C-shaped" steel plate. The side of the first embedded part 4 close to the shear wall steel frame 3 is provided with a hook. The first embedded part 4 is fixedly connected to the shear wall steel frame 3 through the hook, and the first embedded parts 4 are engaged with each other.

[0030] In this embodiment, during the prefabrication stage of the shear wall, according to the wall layout of the structural engineering, when the steel mesh is tied, a certain number of the first embedded parts 4 or the second embedded parts 5 calculated are fixed to the shear wall steel skeleton 3 under the action of the hook, and then the concrete is poured and cured. After curing, the formwork is removed, and the shear wall with the first embedded parts 4 and the second embedded parts 5 embedded is transported to the site, and the positions of the first prefabricated shear wall 1 and the second prefabricated shear wall 2 are located. For the position where the local wall structure is T-shaped or cross-shaped, the first prefabricated shear wall 1 with the first embedded parts 4 embedded is hoisted into place and the exposed parts of the first embedded parts 4 are interlocked.

[0031] Example 2

[0032] like Figure 1 , Figure 3 , Figure 4 and Figure 5 As shown, based on the same concept as the above-mentioned embodiment 1, this embodiment further proposes that a plurality of second embedded parts 5 are provided on both sides of the second prefabricated shear wall 2, the side of the second embedded part 5 away from the shear wall steel frame 3 is a straight plate, and mounting screw holes 6 are provided on the upper and lower sides inside the second embedded part 5, and mounting bolts 7 are penetrated inside the two second embedded parts 5. A bent hook is provided on the side of the second embedded part 5 close to the shear wall steel frame 3, and the mounting screw hole 6 is threadedly matched with the mounting bolt 7, and the two second embedded parts 5 are fixedly connected by the mounting bolts 7.

[0033] In this embodiment, the second prefabricated shear wall 2 with the second embedded part 5 is hoisted into place, the mounting screw holes 6 of the exposed part of the second embedded part 5 are aligned, and the mounting bolts 7 are used to tighten. For the positions where the wall is partially structured in a straight line and a T shape, the formwork is erected on the side where the wall is not set. For the cross-shaped position, since the wall can serve as the formwork, there is no need to support the formwork. Subsequently, the operations of pouring concrete, curing, and removing the formwork can be completed according to the construction requirements.

[0034] In summary, the working steps are:

[0035] First, in the shear wall prefabrication stage, according to the wall layout of the structural engineering, when the steel mesh is tied, a certain number of the first embedded parts 4 or the second embedded parts 5 calculated are fixed to the shear wall steel skeleton 3 under the action of the hook, and then the concrete is poured and cured. After the curing is in place, the formwork is removed, the shear wall with the first embedded parts 4 and the second embedded parts 5 embedded is transported to the site, and the positions of the first prefabricated shear wall 1 and the second prefabricated shear wall 2 are located.

[0036] Secondly, for the position where the local wall structure is T-shaped or cross-shaped, the first prefabricated shear wall 1 with the first embedded part 4 is hoisted into place and the exposed parts of the first embedded part 4 are interlocked with each other, and the second prefabricated shear wall 2 with the second embedded part 5 is hoisted into place and the exposed part of the second embedded part 5 is installed with the screw hole 6 centered and fastened with the installation bolts 7.

[0037] Finally, for the positions where the partial wall structure is in the shape of a straight line or a T, the formwork is set up on the side where the wall is not set up. For the cross-shaped position, there is no need to set up the formwork because the wall can serve as the formwork. Then, the operations of pouring concrete, curing, and removing the formwork can be completed according to the construction requirements.

[0038] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
