Description

Technical Field

[0001] This utility model relates to the field of wall jointing, specifically a jointing plate for a fully cast-in-place concrete exterior wall structure. Background Technology

[0002] Cast-in-place concrete infill wall structures are a commonly used structural form in building engineering. They possess excellent load-bearing capacity and seismic performance, and are widely used in various building types. With the continuous development and improvement of building structures, the application of cast-in-place concrete infill wall structures in building engineering is becoming increasingly widespread, making them an important component of modern architecture.

[0003] A search revealed Chinese patent application number CN221741617U, which discloses an anti-displacement tie plate for cast-in-place exterior walls. The plate includes a horizontal tie plate, a vertical tie plate on the upper surface of the horizontal tie plate, and an installation block on the lower surface of the vertical tie plate. The horizontal tie plate has an internal installation groove. A positioning rod is mounted on the inner wall of the horizontal tie plate, and a sliding block is fixedly connected to the lower surface of the vertical tie plate. This invention works by having the back of the sliding block contact the inner wall of the horizontal tie plate, at which point the positioning rod enters the limiting hole, stabilizing the entire vertical tie plate and ensuring stability during installation. Simultaneously, the sliding block and the fixing plate are both installed inside the installation groove and the limiting groove, enhancing the anti-tipping effect of the horizontal tie plate and preventing it from wobbling. Furthermore, the positioning plate on the back of the installation block also enters the positioning groove, ensuring the stability of the installation block.

[0004] However, both horizontal and vertical tie joint panels are thin-walled hollow structures. It is difficult to create installation grooves inside the horizontal and vertical tie joint panels, which increases processing costs. In addition, during actual installation, the connection position between the horizontal and vertical tie joint panels needs to be adjusted according to the working conditions. However, the connection position between the horizontal and vertical tie joint panels in this cast-in-place anti-displacement tie joint panel for exterior walls is fixed and cannot be adjusted, which leads to a narrow range of applications.

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] Please see Figures 1-4 In this embodiment of the utility model, a tie plate for a fully cast-in-place concrete exterior wall structure includes a transverse tie plate 1 and a longitudinal tie plate 2. The upper surface of the transverse tie plate 1 is provided with multiple first grooves 11 that are equidistantly distributed. The two side walls of the longitudinal tie plate 2 are provided with multiple second connecting grooves 21, and the multiple second connecting grooves 21 are arranged at equal intervals.

[0023] The transverse seam plate 1 and the longitudinal seam plate 2 are vertically connected and fixed by a connecting unit 3. The connecting unit 3 includes two symmetrically distributed clamping plates 301. The two symmetrically arranged clamping plates 301 are located on both sides of the lower end of the longitudinal seam plate 2. Multiple bolt assemblies 304 are provided in the length direction of the clamping plate 301. The multiple bolt assemblies 304 cooperate with the first strip groove 11 and the second connecting groove 21 to lock the clamping plate 301 between the transverse seam plate 1 and the longitudinal seam plate 2.

[0024] The first groove 11 is integrally formed with the transverse joint plate 1, and the second connecting groove 21 is integrally formed with the longitudinal joint plate 2. The cross-sections of the first groove 11 and the second connecting groove 21 are both "T" shaped groove structures. The cross-section of the clamping plate 301 is an "L" shaped structure, and the two ends of the clamping plate 301 abut against the transverse joint plate 1 and the longitudinal joint plate 2, respectively.

[0025] The connecting unit 3 also includes a plurality of first through holes 302 that are equidistantly distributed at one end of the clamping plate 301, and a plurality of second through holes 303 that are equidistantly distributed at the other end of the clamping plate 301; the spacing between the plurality of first through holes 302 is the same as the spacing between the plurality of first strip grooves 11, and the spacing between the plurality of second through holes 303 is the same as the spacing between the plurality of second connecting grooves 21.

[0026] The bolt assembly 304 includes a nut 3041 located in the first slot 11 or the second connecting slot 21, and a screw 3042 passing through the first through hole 302 or the second through hole 303 and threadedly connected to the nut 3041; the nut 3041 is a T-nut.

[0027] In this embodiment, by cooperating with the first strip groove 11 and the second connecting groove 21, the longitudinal joint plate 2 can be quickly and vertically connected to the transverse joint plate 1. Compared with the existing glue connection, this connection method is simple and convenient, and the connection strength and stability are both high. In addition, this connection structure is easy to adjust. The clamping plate 301 can move along the length direction of the first strip groove 11. After moving to the designated position, the clamping plate 301 can be limited to that position by the bolt assembly 304, thereby improving the applicability of the device.

[0028] Specifically, this solution mainly includes a transverse joint plate 1, a longitudinal joint plate 2, and a connecting unit 3. The upper surface of the transverse joint plate 1 is provided with multiple equidistant first grooves 11, and the two sides of the longitudinal joint plate 2 are provided with multiple equidistant second connecting grooves 21. The first grooves 11 and 12 have the same cross-sectional size and structure, and are both T-shaped grooves. This T-shaped groove is integrally formed with the transverse joint plate 1 or the longitudinal joint plate 2, which has a stable structure and does not require additional grooving, thus reducing the workload.

[0029] The transverse joint plate 1 and the longitudinal joint plate 2 are fixedly connected by a connecting unit 3. The connecting unit 3 mainly includes two clamping plates 301 and multiple bolt assemblies 304. The clamping plates 301 have an "L" shaped cross-section. The two side walls of the clamping plates 301 are respectively provided with a first through hole 302 and a second through hole 303. The multiple bolt assemblies 304 are located between the clamping plates 301 and the T-slot. When the bolt assemblies 304 are not tightened, the two clamping plates 301 can move along the length direction of the first strip groove 11. When the bolt assemblies 304 are tightened, the clamping plates 301 will be fixed at any position along the length direction of the first strip groove 11. Therefore, the connection position of the longitudinal joint plate 2 on the transverse joint plate 1 can be adjusted according to the working conditions, which has high flexibility.

[0030] The bolt assembly 304 mainly includes a nut 3041 and a screw 3042. The nut 3041 is a T-nut. When the screw 3042 is not tightened, the nut 3041 can slide in the first slot 11. When the screw 3042 is tightened, the nut 3041 will rotate a certain angle under the action of the screw 3042. That is, the nut 3041 is horizontal in the first slot 11. At this time, the length of the nut 3041 is greater than the bottom slot width of the first slot 11. The screw 3042 will drive the nut 3041 to move upward, so that the nut 3041 is pressed and fixed against the upper wall of the first slot 11, which restricts the movement of the clamping plate 301.

[0031] In addition, the T-shaped groove in this solution includes the first groove 11 and the second connecting groove 21, which can also be used to increase the contact surface between the transverse tie plate 1 and the longitudinal tie plate 2 and the concrete, thereby further improving the connection strength between the tie plate and the cast-in-place concrete infill wall and ensuring a stable connection between the tie plate and the cast-in-place concrete infill wall.

[0032] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
