[0023] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] See also Figure 1-5 The utility model provides a technical solution: a support assembly cast on an assembled concrete prefabricated component, comprising a concrete prefabricated component body 3, one end of which is provided with a support assembly 1; the support assembly 1 is provided with a plurality of support columns 12 on one end of the concrete prefabricated component body 3, and a steel bar 2 is pre-embedded at one end of the concrete prefabricated component body 3; this structure can be higher than the height of the steel bar 2 by providing a plurality of support columns 12, so that the steel bar 2 is prevented from being scratched during the process of stacking the concrete prefabricated component body 3, and the steel bar 2 is protected;

[0025] The support assembly 1 includes an embedded connector 13 arranged inside the main body 3 of the precast concrete component. The embedded connector 13 is a "T"-shaped structure when viewed from the front, and the inner wall of the embedded connector 13 is threadedly connected to the support column 12; this structure facilitates the connection of the support column 12 by providing the embedded connector 13, and at the same time facilitates the stable lifting and lowering of the support column 12; a nut groove 11 is provided on the top of the support column 12, and a groove is provided on one side of the support column 12, and a support spring 16 is fixedly connected inside the groove; this structure facilitates the use of a wrench tool to rotate the support column 12 by providing the nut groove 11, so that the support column 12 rises; one end of the support spring 16 is fixedly connected to the limit block 15, and one side of the limit block 15 is fixedly connected to the second limit rod 17; this structure can support the limit block 15 to pop out through the support spring 16, so that it can be stacked horizontally according to the position of the limit block 15. The second limiting rod 17 is inserted into the inside of the support spring 16, and the limiting block 15 and the second limiting rod 17 are both slidably connected to the support column 12; this structure can play a certain limiting role on the support spring 16 by setting the second limiting rod 17, so as to prevent the support spring 16 from shaking and tilting excessively; the embedded connecting piece 13 is fixedly connected with the first limiting rod 14, and the embedded connecting piece 13 is movably connected with the support column 12, and a groove is provided at the bottom of the support column 12, and the first limiting rod 14 is inserted into the groove; this structure can not only limit the shaking of the support column 12 when the support column 12 is raised or lowered by setting the first limiting rod 14, but also support the support column 12; the first limiting rod 14 is located at the lower end of the support column 12.

[0026] Working principle: When in use, a wrench tool can be inserted into the nut groove 11 during the longitudinal stacking of the precast concrete component body 3, and then the wrench is turned to drive the support column 12 to rotate. The support column 12 moves upward from the embedded connecting piece 13 during the rotation, and the lower end of the support column 12 slides on the outer wall of the first limit rod 14 during the rotation. When the support column 12 is fully unfolded, the limit block 15 automatically pops out with the support of the support spring 16. When the limit block 15 moves, the support spring 16 slowly expands, so that the limit block 15 is located on the side of the precast concrete component body 3 to control the placement spacing between the precast concrete component bodies 3, thereby avoiding scratches on the side of the precast concrete component body 3, thereby ensuring the quality of the precast concrete component body 3.
