Description

Technical Field

[0001] This utility model relates to the field of prefabricated wall panel connection technology, and in particular to a prefabricated wall panel connector. Background Technology

[0002] Precast wall panels are building components that are prefabricated in a factory and assembled on-site, and are widely used in prefabricated construction. Compared to traditional cast-in-place concrete walls, precast wall panels offer advantages such as high construction efficiency, stable quality, reduced on-site wet work, and lower labor costs. To ensure a secure connection between precast wall panels during installation, precast wall panel connectors are typically used. These connectors reliably fix adjacent wall panels, forming a unified structure and improving the building's seismic performance and durability. Properly designed connectors not only improve installation accuracy but also enhance the strength of the wall panel joints, preventing loosening or cracking caused by external forces.

[0003] Existing precast wall panel connectors typically employ bolting, welding, plugging, or a combination of these methods. For example, some connectors use pre-embedded bolts, secured with nuts to connect the wall panels; others use pre-drilled slots at the wall panel ends, fixing them by connecting reinforcing bars or grouting sleeves. However, when using bolted connections, it is necessary to ensure that the bolt positions on the connectors are aligned with the pre-drilled holes. If there is a deviation, temporary drilling is required, which is cumbersome. Therefore, a new precast wall panel connector is proposed to solve these problems. Utility Model Content

[0004] To overcome the above shortcomings, this utility model provides a prefabricated wall panel connector, which aims to improve the problem in the prior art where the bolt installation position on the connector is fixed and re-drilling is required if the installation position deviates from the reserved hole position.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A precast wall panel connector, comprising:

[0007] The connecting frame, which serves as the main structure of the connector, has the wall panel slidably connected inside it. The whole frame is C-shaped and has a limiting groove running through it. The limiting groove extends to the upper and lower sides inside the connecting frame.

[0008] The slider slides inside the limiting groove, and its upper and lower sides slide in the extension grooves on the upper and lower sides of the limiting groove to adapt to the position of the reserved hole of different wall panels, and has bolt holes inside.

[0009] The first fixing bolt has a threaded connection inside the bolt hole and is used to connect the wall panel and the slider.

[0010] The second fixing bolt is located inside the connecting frame and is threaded into the slider, allowing it to move synchronously with the slider.

[0011] The gasket, located between the fixing bolt and the connecting frame, is a ring-shaped sheet formed by integral stamping and is used to increase the friction between the two.

[0012] As a further description of the above technical solution:

[0013] The top of the connecting frame has a through groove, which is connected to the extension groove at the top of the limiting groove.

[0014] As a further description of the above technical solution:

[0015] The second fixing bolt is located inside the through groove and can move inside the through groove.

[0016] As a further description of the above technical solution:

[0017] The lower surface of the gasket is in contact with the upper surface of the connecting frame.

[0018] As a further description of the above technical solution:

[0019] The diameter of the gasket is greater than the spacing of the through groove, and the inner diameter of the gasket is smaller than the end of the fixing bolt.

[0020] As a further description of the above technical solution:

[0021] The gasket is made of stainless steel.

[0022] This utility model has the following beneficial effects:

[0023] In this invention, the connecting frame is placed at the joint of two wall panels. The fixing bolt is aligned with the bolt hole by adjusting the slider, and then the connection is completed by twisting. After installation, pressure is applied by the fixing bolt to make the gasket fit tightly against the connecting frame. The friction enhances the stability of the connecting frame. Through the cooperation between the above structures, the operation of temporary drilling is avoided, and the efficiency of prefabricated wall panel assembly is improved. Attached Figure Description

[0029] 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.

[0030] Reference Figures 1-3 This utility model provides an embodiment of a prefabricated wall panel connector, comprising: a connecting frame 1, which serves as the main structure of the connector, with wall panels slidably connected inside it, forming a C-shape, and having a limiting groove 2 extending through it. The limiting groove 2 extends to the upper and lower sides of the connecting frame 1. During installation, the connecting frame 1 can be placed at the joint of two wall panels, positioned in the middle; a slider 3, which slides inside the limiting groove 2, with its upper and lower sides sliding in the extension grooves on the upper and lower sides of the limiting groove 2 to accommodate the positions of pre-drilled holes in different wall panels, and has bolt holes 8 inside, which can be adjusted according to the position of the pre-drilled bolt holes, avoiding the need for temporary drilling during installation and improving work efficiency; a first fixing bolt 4, which is threaded into the bolt hole 8 and used to connect the wall panel to the slider 3; a second fixing bolt 6, which is located inside the connecting frame 1 and threaded into the slider 3, and can move synchronously with the slider 3; and a gasket 7, located between the second fixing bolt 6 and the connecting frame 1. The ring-shaped sheet is integrally stamped to increase the friction between the two. The second fixing bolt 6 is used to lock the slider 3 in a preset position. After the wall panel and the connecting frame 1 are initially connected, the second fixing bolt 6 can be twisted downwards, and the upper end of it will squeeze the gasket 7. During the twisting process, the slider 3 itself will be subjected to an upward force, making it close to the upper edge of the limiting groove 2, and the gasket 7 will move under force and fit against the top of the connecting frame 1, further fixing the position of the slider 3. The top of the connecting frame 1 has a through groove 5, which is connected to the extension groove at the top of the limiting groove 2. The second fixing bolt 6 is located inside the through groove 5 and can move inside the through groove 5. The movement of the slider 3 will drive the second fixing bolt 6 to move inside the through groove 5. The lower surface of the gasket 7 fits against the upper surface of the connecting frame 1. The diameter of the gasket 7 is larger than the opening distance of the through groove 5, and the inner diameter of the gasket 7 is smaller than the end of the second fixing bolt 6 to ensure the stability of the gasket 7. The gasket 7 is made of stainless steel, which makes it corrosion resistant.

[0031] Working principle: When using this connector to laterally join two door panels, firstly, the connecting frame 1 is placed at the joint of the two door panels. Then, by pushing the slider 3, the fixing bolt 4 inside the slider 3 aligns with the pre-drilled bolt holes in the wall panel. Then, by twisting, both wall panels are connected to the connecting frame 1. This method can accommodate wall panels with pre-drilled bolt holes in different positions, eliminating the need for temporary drilling during installation. As the slider 3 slides, it will synchronously drive the fixing bolt 6 to move. After the wall panel is installed, the fixing bolt 6 is tightened downwards, pressing the washer 7 tightly against the top of the connecting frame 1. Through the friction between the washer 7 and the connecting frame 1, the positions of the connecting frame 1 and the slider 3 are further fixed, ensuring the installation is secure.

[0032] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
