Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a support-free precast column connection structure. Background Technology

[0002] The connection between precast columns is usually done by "wet connection": the upper and lower precast columns are first fixed by lateral support, and then mortar is poured at the connection. It takes 2-28 days for the mortar to reach a certain strength before the lateral support can be removed for subsequent construction.

[0003] Currently, one type of prefabricated column connection structure that does not require support is generally time-consuming and inefficient, which delays the construction progress and makes it difficult to further leverage the speed advantage of prefabricated buildings. Utility Model Content

[0004] The purpose of this invention is to solve the problems of high time consumption and low efficiency of general support in the existing technology, which delays the construction progress and makes it difficult to further give full play to the speed advantage of prefabricated buildings. Therefore, this invention proposes a support-free prefabricated column connection structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a support-free precast column connection structure, comprising a first precast column, a second precast column above the first precast column, the first precast column and the second precast column being connected by a connecting component, the connecting component comprising a first cross-shaped steel plate disposed at the bottom end of the second precast column, a second cross-shaped steel plate disposed at the top end of the first precast column, and the first cross-shaped steel plate and the second cross-shaped steel plate being fixed together by bolts.

[0006] Preferably, both ends of the first cross-shaped steel plate and the second cross-shaped steel plate are provided with butt steel clamps, and the butt steel clamps are fixed to the first cross-shaped steel plate and the second cross-shaped steel plate by bolts.

[0007] Preferably, the first cross-shaped steel plate has multiple first bolt holes at each of its four ends, and the second cross-shaped steel plate has multiple second bolt holes at each of its four ends.

[0008] Preferably, the mating steel clamp is provided with a plurality of third bolt holes and fourth bolt holes that match the first bolt holes and the second bolt holes.

[0009] Preferably, the first cross-shaped steel plate and the second cross-shaped steel plate are respectively embedded in the inner side of the opposite end of the second precast column and the first precast column.

[0010] Preferably, the dimensions and positions of the first and second cross-shaped steel plates are consistent, and the dimensions and positions of the third and fourth bolt holes are consistent with those of the first and second bolt holes, respectively.

[0011] Compared with the prior art, the advantages and positive effects of this utility model are as follows: In this utility model, when the first precast column and the second precast column are connected and installed, the first precast column and the second precast column can be accurately connected by the guide of the first cross-shaped steel plate and the second cross-shaped steel plate. After the accurate connection is completed, the connecting steel clamps are placed on both sides of the first end of the first cross-shaped steel plate and the second cross-shaped steel plate. The first bolt hole and the third bolt hole are aligned, the second bolt hole and the fourth bolt hole are connected, and then the bolt body is used to fix it, thereby achieving the effect of quickly locking the first cross-shaped steel plate and the second cross-shaped steel plate without the need for other lateral support [1]. This device is a convenient support device for construction when two or more precast concrete columns are connected, [2] and quickly realizes the support and fixation of precast concrete columns.
