DETAILED DESCRIPTION

[0056] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0057] Example 1

[0058] This embodiment provides a shear wall vertical joint splicing structure, such as Figures 1 to 3 As shown, it includes: a plurality of first embedded components 1, a plurality of second embedded components 2, a plurality of third embedded components 3, a plurality of anchoring clamps 4 and a plurality of steel strands 5; the first embedded components 1 and the third embedded components 3 are respectively embedded in the upper part and the lower part of the first shear wall 100 to be spliced, and the first embedded components 1, the second embedded components 2, and the third embedded components 3 are respectively embedded in the upper part, the middle part and the lower part of the second shear wall 200 to be spliced; the two ends of the steel strand 5 are respectively connected to the first embedded component 1 of the first shear wall 100 and the third embedded component 3 of the second shear wall 200; and the two ends of the steel strand 5 are respectively connected to the first embedded component 1 of the second shear wall 200 and the third embedded component 3 of the first shear wall 100; the second embedded component 2 is provided with a receiving groove 21 for arranging the steel strand 5; the anchoring clamp 4 is clamped with the steel strand 5.

[0059] Specifically, when prefabricating the shear wall, the first embedded component 1, the second embedded component 2, and the third embedded component 3 are embedded in advance, wherein two first embedded components 1 are embedded in the upper part of the first shear wall 100 and the second shear wall 200, respectively, the heights of the two first embedded components 1 are consistent and they are located on different sides of the shear wall, the first embedded component 1 on the first shear wall 100 is arranged correspondingly to the first embedded component 1 on the second shear wall 200, and two third embedded components 3 are embedded in the upper part of the first shear wall 100 and the second shear wall 200, respectively, the heights of the two third embedded components 3 are consistent and they are located on different sides of the shear wall, the third embedded component 3 on the first shear wall 100 is arranged correspondingly to the third embedded component 3 on the second shear wall 200. At least one second embedded component 2 is embedded in the second shear wall 200, and the specific number of embedded components can be flexibly adjusted based on the size of the shear wall.

[0060] The first embedded component 1 on the first shear wall 100 is connected to the third embedded component 3 on the same side of the second shear wall 200 through the steel strand 5 to form a cross anchoring on the same side.

[0061] like Figure 4 and Figure 5 As shown, the first embedded component 1 includes: a main body 11, a reinforcing fixing part 3212, and an adjusting part 13; the first end of the main body 11 is fixedly connected to the reinforcing fixing part 3212; the steel strand 5 passes through the reinforcing fixing part 3212 and the main body 11 in sequence, and then passes through the second end of the main body 11 to connect with the third embedded component 3; the adjusting part 13 passes through a side wall of the main body 11 and abuts against the steel strand 5. The reinforcing fixing part 3212 can make the entire first embedded component 1 more firmly embedded in the shear wall and will not be easily unanchored. Each first embedded component 1 is used with a steel strand 5, and when the shear wall is prefabricated, the first embedded component 1 is first fixed to the steel strand.

[0062] Preferably, the main body 11 is a hollow steel pipe; the first end of the hollow steel pipe is provided with a thread, and the hollow steel pipe is connected to the reinforcing fixing part 3212 by a thread; the steel strand 5 passes through the inner cavity of the hollow steel pipe; and an adjusting part 13 is provided on one side wall of the hollow steel pipe. The adjusting part 13 can be implemented by bolts, and correspondingly, a threaded hole is provided on one side wall of the hollow steel pipe for the bolts to pass through. At the same time, the steel strand 5 can be clamped in the hollow steel pipe by the bolts to prevent the steel strand 5 from being unanchored. The main body 11, the reinforcing fixing part 3212, and the adjusting part 13 are all embedded in the shear wall, so before the shear wall is prefabricated, the steel strand 5 needs to be clamped. After the prefabrication is completed, one end of the steel strand 5 is embedded in the shear wall, and the other end is reserved to be connected with the third embedded component 3 when the shear wall is spliced.

[0063] The reinforcing fixing portion 3212 is a solid steel pipe; the solid steel pipe is provided with a through hole with a thread for connecting the hollow steel pipe and allowing the steel strand 5 to pass through.

[0064] like Figure 6As shown, the second embedded component 2 includes: an embedded component body; the embedded component body is bent to form a receiving groove 21, and the receiving groove 21 is used to limit the displacement of the steel strand 5; the side wall of the receiving groove 21 is bent inward to form an auxiliary positioning portion 22, and half of the receiving groove 21 of the embedded component body is embedded in the shear wall, and the remaining half is exposed to the outside. The receiving groove 21 is as wide as the shear wall and has a height of 20-30cm. That is, the embedded component body is generally shaped like a channel steel, and is bent inward at the flange for a length of 5cm. Its function is to serve as auxiliary positioning. First, the wall with the second embedded component 2 is hoisted, and then when the wall on the other side is hoisted, it can be hoisted in close contact with the second embedded component 2 to achieve the functions of auxiliary positioning and controlling the distance between walls; second, it improves the lateral force stiffness; third, it can be used as a template fixing device. In addition, the second embedded component body can also be implemented with square steel.

[0065] like Figure 7 and Figure 8 As shown, the third embedded component 3 includes: an embedded part 31 and a fixed part 32; the embedded part 31 is embedded in the first shear wall 100 and the second shear wall 200, and the fixed part 32 is fixedly connected to the embedded part 31 and to the steel strand 5.

[0066] The embedded part 31 is provided with an external thread, so as to increase the bonding force between the third embedded part and the shear wall. The fixing part 32 is provided in a circular ring shape for the steel strand 5 to pass through and fix. The fixing part 32 is exposed outside the shear wall.

[0067] like Fig. 9 As shown, the anchoring fixture 4 is set in a U shape, and threads are set at both ends; the steel strand 5 is set in the U-shaped anchoring fixture 4. In the specific use process, the steel strand 5 is first passed through the fixing part 32, and then anchored by the anchoring fixture 4.

[0068] This embodiment directly connects two shear wall panels through the first embedded component, the third embedded component, and the steel strand, which is convenient and simple to operate; the second embedded component in the middle can be used to assist in positioning and installation, and can also improve the lateral stiffness; the third embedded component is arranged at the lower part, which is convenient for fixing the steel strand construction and increasing the connection speed. The steel strand can greatly improve the installation fault tolerance rate and the force transmission is clear. Compared with the traditional steel plate bolt connection, it can greatly reduce costs and improve economic benefits.

[0069] Example 2

[0070] This embodiment provides another type of shear wall vertical seam splicing structure. According to the actual stress conditions, the number of third embedded components is increased and the connection form is changed. That is, the difference between this embodiment and Embodiment 1 is that at least one group of third embedded components 3 is embedded in the middle of the first shear wall 100 and the second shear wall 200.

[0071] Next, an explanation is given by taking the case where two sets of third embedded components 3 are embedded in the middle of the first shear wall 100 and the second shear wall 200 as an example:

[0072] like Fig.10 and Fig.11 As shown, the third embedded component 3 is evenly distributed from top to bottom in the middle of the shear wall; the first end of the steel strand 5 is connected to the first embedded component 1 of the first shear wall 100, and the second end of the steel strand 5 passes through the third embedded component 3 of the second shear wall 200 and the first embedded component 1 of the first shear wall 100 in sequence, and finally connects to the third embedded component 3 of the second shear wall 200; and the first end of the steel strand 5 is connected to the first embedded component 1 of the second shear wall 200, and the second end of the steel strand 5 passes through the third embedded component 3 of the first shear wall 100 and the third embedded group of the second shear wall 200 in sequence, and finally connects to the third embedded component 3 of the first shear wall 100; the anchor clamp 4 is clamped with the second end of the steel strand 5, so that the two steel strands 5 form a same-side cross anchoring.
