[0021] The technical solution of the present utility model is further described below in conjunction with the accompanying drawings and embodiments.

[0022] The embodiment of the utility model provides a prefabricated shear wall connection structure for splicing prefabricated walls 1, comprising:

[0023] The mounting member 2 has a plurality of mounting surfaces for mounting the prefabricated wall 1;

[0024] A plurality of fixing members corresponding to the plurality of mounting surfaces, the fixing members include fixing blocks 3 arranged on the mounting surfaces and located on both sides of the prefabricated wall 1, and an adjusting portion arranged on the mounting member 2 and connected to the two fixing blocks 3, for adjusting the distance between the two fixing blocks 3 so that the two fixing blocks 3 abut against or separate from the side surfaces of the prefabricated wall 1.

[0025] In the embodiment of the utility model, the mounting member 2 is a rectangular structure, and its rectangular structure has mounting surfaces with different orientations, and can connect prefabricated walls 1 in different installation positions. When installing two prefabricated walls 1 on the same plane, it is only necessary to place the two prefabricated walls 1 on two opposite mounting surfaces. When installing two prefabricated walls 1 that need to be vertical, it is only necessary to place the two prefabricated walls 1 on two adjacent mounting surfaces. Compared with the traditional splicing method, the present scheme has more splicing methods and is suitable for different construction sites. Moreover, under the action of the fixing member, when the prefabricated wall 1 is placed on the mounting surface, the distance between the two fixing blocks 3 can be adjusted through the adjustment part, so that the two fixing blocks 3 are quickly pressed on the prefabricated wall 1 to fix it quickly. The dry connection method is simpler and more convenient than the traditional casting method. While ensuring stability, it is also convenient for later disassembly and replacement.

[0026] Specifically, Figure 1 As shown, when it is necessary to connect each prefabricated wall 1 in a "T" shape or a cross shape, by assembling fixings on each installation surface, and abutting each prefabricated wall 1 on each installation surface respectively to connect through fixings, it is also possible to assemble fixings on three adjacent installation surfaces to connect three prefabricated walls 1 accordingly, such as Figure 2 As shown, when two prefabricated walls 1 are required to be connected to form a corner structure, the corresponding prefabricated walls 1 can be installed by assembling fixings on two adjacent sets of installation surfaces, so that multiple prefabricated walls 1 can be connected to present various forms.

[0027] like Figure 4 As shown, the adjustment part includes a driving block 4 slidably arranged on the mounting member 2 and respectively connected to the two fixing blocks 3, and a bidirectional screw 6 rotatably arranged on the mounting member 2, and both ends of the bidirectional screw 6 are respectively threadedly connected to the two driving blocks 4.

[0028] Based on the above scheme, specifically when the two fixed blocks 3 are adjusted through the adjustment part, the bidirectional screw 6 is rotated so that the bidirectional screw 6 rotates on the mounting part 2, and the driving block 4 is limited and cannot move. Therefore, the two driving blocks 4 can be driven to move closer to or away from each other under the drive of the bidirectional screw 6, so that the two driving blocks 4 drive the two fixed blocks 3 to move closer to or away from each other, so that the prefabricated wall 1 is pressed and fixed, or the restriction on it is released.

[0029] Specifically, in order to facilitate the adjustment of the bidirectional screw 6, a nut 7 is provided in the middle of the bidirectional screw 6, which can be clamped on the nut 7 by tools such as a wrench, making the adjustment of the bidirectional screw 6 more labor-saving.

[0030] Specifically, in order to increase the installation strength of the prefabricated wall 1, as Figure 4 As shown, a protrusion 5 is provided at one end of the fixing block 3 away from the installation surface, and the protrusion 5 is snapped into the prefabricated wall 1. The prefabricated wall 1 is grooved on its side during production, and the groove structure is L-shaped, so that it adapts to the structure of the fixing block 3. When the prefabricated wall 1 is installed through the fixing block 3, the protrusion 5 of the fixing block 3 is snapped into the groove on the side of the prefabricated wall 1, ensuring the firmness of the installation of the prefabricated wall 1, and after the installation is completed, the fixing block 3 is completely snapped into the groove, ensuring the original flatness of the prefabricated wall 1.

[0031] like Figure 5 As shown, the mounting member 2 includes two first connecting plates 9 and two second connecting plates 10 that are arranged in a mirror image. The two second connecting plates 10 are clamped between the two first connecting plates 9. A tie rod bolt 11 is passed between the two first connecting plates 9 and passes through the second connecting plates 10.

[0032] In the embodiment of the utility model, the mounting member 2 is assembled by two first connecting plates 9 and two second connecting plates 10, and the fixing members on the second connecting plates 10 can be installed and produced according to the actual assembly situation. The assembled structure is convenient for separate processing and production, and also convenient for subsequent transportation. Figure 3 As shown, when assembling two prefabricated walls 1 on the same plane, in order to reduce the occupied area, the two second connecting plates 10 can be removed so that the two first connecting plates 10 are close to each other, and the width of the driving block 4 is the same as the thickness of the first connecting plate 9 and the second connecting plate 10, so that the driving block 4 and the bidirectional screw 6 will not occupy the area of ​​the outer surface, and the two first connecting plates 10 can be completely structured, thereby effectively reducing the actual occupied space of the mounting parts 2 when assembling the two prefabricated walls 1.

[0033] Specifically, Figure 1As shown, the first connecting plate 9 is provided with a plurality of positioning rings 8 coaxial with the pull rod bolts 11, and the positioning rings 8 are passed through the adjacent second connecting plate 10. When the mounting member 2 is assembled, that is, when the first connecting plate 10 and the second connecting plate 10 are connected, the positioning rings 8 of the first connecting plate 9 can be passed through the second connecting plate 10 to play a role in positioning and installation.

[0034] In summary, through the setting of the mounting member 2, the prefabricated walls 1 at different installation positions can be connected. Specifically, when multiple prefabricated walls 1 are spliced ​​into a "T" shape or a cross shape, the prefabricated walls 1 are respectively installed on the first connecting plate 9 and the second connecting plate 10, and by rotating the bidirectional screw 6, the two driving blocks 4 can be driven to approach or move away from each other under the drive of the bidirectional screw 6, so that the two driving blocks 4 drive the two fixing blocks 3 to approach or move away from each other, so that the prefabricated wall 1 is pressed and fixed. The dry connection method is adopted, which ensures stability while facilitating later disassembly and replacement.

[0035] When installing multiple planar prefabricated walls 1, the two second connecting plates 10 are removed, and the two first connecting plates 9 are brought close together and connected by tie bolts 11. This solution includes a variety of different arrangements, which is suitable for quick connection of prefabricated walls 1 in different construction sites, and the connection is quick, stable and easy to operate.

[0036] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the purpose and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
