Description

Technical Field

[0001] The utility model relates to the technical field of embedded parts, in particular to a building construction embedded structure. Background Art

[0002] Embedded parts are components pre-installed in concealed projects of building construction. They are used for overlapping of superstructures and installation and fixation of foundations of external engineering equipment.

[0003] An embedded steel claw is fixed on the bottom side of the embedded part. The provision of the steel claw makes the transportation of the embedded part difficult, that is, it occupies a large amount of space during transportation and is prone to scattering. Therefore, this solution provides an embedded structure in which the steel claw and the base plate can be separated for loading and transportation, thereby reducing the difficulty of transportation and facilitating quick assembly when in use. Utility Model Content

[0004] The utility model aims at least to solve the problem in the prior art that the base plate and the steel claws are mostly fixed by welding.

[0006] Preferred technical solution 1: The vertical limiting mechanism includes a vertical seat that is in docking contact with the inner end of each group of the protrusions, and a vertical groove opened on the outer side of the vertical seat is used for the vertical section of the steel claw to be inserted. The vertical limiting mechanism also includes a limiting component for limiting the contact state between the vertical seat and the protrusion.

[0007] Preferred technical solution two: The limiting assembly includes a connecting ring that can be detachably installed at the center of the base plate, and four groups of connecting rods are hingedly connected to the circumferential side of the connecting ring. The end of each group of connecting rods is hingedly connected to a corresponding group of vertical seats. During assembly, the connecting ring is assembled to the base plate to push the multiple groups of vertical seats away from each other and contact the inner end of the convex seat.

[0008] Preferred technical solution three: The vertical section of the steel claw is rotatably sleeved with multiple groups of movable cams, and different orientations can be switched by rotating the movable cams.

[0009] Preferred technical solution four: the vertical section of the steel claw is a threaded rod, and the movable pawl is sleeved on the threaded rod through a threaded hole, so that the height position of the movable pawl can be changed during the rotation of the movable pawl.

[0010] The above structure enables this solution to have the following beneficial effects:

[0011] 1. The base plate, steel claws and vertical limit mechanism are separated and can be stacked separately during transportation to reduce the space occupied during transportation;

[0012] 2. The setting of the movable claws can enhance the connection stability between the embedded structure and the foundation, and since the direction and height position of the movable claws can be adjusted, the posture of the embedded structure can be further enriched.
