Description

Technical Field

[0001] The utility model relates to the technical field of building construction engineering, in particular to a connecting piece for assembled prefabricated composite panels. Background Art

[0002] Prefabricated prefabricated panels are usually made of concrete and steel bars. They are usually pre-produced in the factory and then transported to the construction site for assembly. The design of prefabricated prefabricated panels allows them to be quickly connected to wall panels and other prefabricated components to construct walls, floors and roofs. During construction, the composite panels are usually hoisted to the corresponding location, and then concrete is poured between the panels and on top of the panels to fix them. However, prefabricated prefabricated composite panels are generally not connected and fixed to each other. In the corresponding places with heavy loads, the stability is insufficient, which may cause the overall load-bearing capacity of the building structure to decrease and increase the safety risk of the building. Insufficient stability may affect the functionality of the composite panels. For example, vibration may occur when used on the roof or ground, affecting the comfort of the user. Utility Model Content

[0003] The purpose of the utility model is to address the above-mentioned deficiencies and provide a connector for assembled prefabricated composite panels to achieve higher structural stability to ensure load-bearing capacity.

[0005] Two symmetrical hook plates arranged up and down, one end of each hook plate being in an arc shape, and each hook plate being provided with an insertion rod inserted into and passing through the other hook plate;

[0006] A threaded rod, which is rotatably arranged on one of the insertion rods, a threaded ring is hingedly arranged at a position of the hook plate corresponding to the threaded rod, and an internal thread corresponding to the threaded rod is provided on the inner wall of the threaded ring;

[0007] The threaded rod is located in the threaded ring. The threaded rod is rotated to make it move linearly in the threaded ring, thereby driving one of the hook plates to approach or move away from the other hook plate.

[0008] Furthermore, a plug post is provided at the other end of the threaded rod away from the connection point with the insertion rod, and the plug post is used to adapt to and install a handle tool to rotate and adjust the threaded rod.

[0009] Furthermore, a hook locking device is provided on the hook plate located above, and the hook locking device is used to hook the steel bar structure located above the hook plate.

[0010] Furthermore, the hook locking device includes a support rod connected to the hook plate, a telescopic rod hingedly arranged on the support rod, and a hook rotatably installed on the moving end of the telescopic rod. The telescopic rod consists of a sleeve and a rod body threadedly arranged in the sleeve, and the hook is arranged on the rod body.

[0011] Furthermore, anti-slip grooves are provided on opposite sides of the two hook plates, and the anti-slip grooves are used to prevent the steel bar device from sliding.

[0012] Furthermore, the threaded ring is composed of two semi-annular arc-shaped frames that are hinged together, and a fixing piece is provided at the other end of the two arc-shaped frames away from the hinged connection.

[0013] The beneficial effects of the utility model are embodied in:

[0014] The utility model places two hook plates symmetrically on the upper and lower sides of the above-mentioned steel bars, and inserts two insertion rods into the corresponding hook plates respectively, so that the two hook plates are initially fixed, and the two hook plates are close to each other and gradually close to the steel bars on the sides of the composite plate body, and the threaded ring in the above-mentioned is in an open state at this time, and the threaded rod will pass through the opened threaded ring as the hook plates move, and then, the threaded ring is closed, so that the threads on the inner wall of the threaded ring and the threads on the outer wall of the threaded rod are threadedly connected to each other, so that the threaded rod can be manually rotated to finely adjust the relative distance between the two hook plates until the arc-shaped end of the hook plate is stuck on the outside of the steel bar. The design of the threaded rod and the threaded ring can be adjusted accordingly according to the above-mentioned method, and after the adjustment is completed, the two hook plates can be limited and prevented from falling off without moving the structure, thereby fixing the corresponding two composite plate bodies, so that the structure at this location has a high structural stability to ensure the load-bearing capacity.
