Large prefabricated columns are one of the key components in prefabricated frame buildings, involving the safety of the entire building. The hoisting of prefabricated columns and the connection process with cast-in-place structures affect the quality, safety and construction period of the entire project, and are crucial processes in the construction process.

[0003] In order to achieve accurate positioning and installation of prefabricated columns, it is generally adopted to install diagonal braces on one side of the prefabricated columns to support the prefabricated columns. The specific method is to reserve fixed embedded parts on the prefabricated columns and floor slabs, and use steel pipes for diagonal connection and support. However, the embedded parts of prefabricated columns have a great impact on the decoration of the columns in the later stage, which is not convenient for later construction. In addition, the method of installing diagonal braces on one side of the prefabricated columns also has the problem of large shaking of the prefabricated columns during the installation stage.

[0004] Therefore, how to facilitate the subsequent column construction while ensuring the stability of the diagonal bracing of the prefabricated column has become an urgent problem to be solved. Utility Model Content

[0035] In order to make the purpose, technical solution and advantages of the embodiments of the utility model clearer, the technical solution in the embodiments of the utility model will be clearly and completely described below in conjunction with the accompanying drawings. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0036] Example 1

[0037] like Figure 1As shown, this embodiment proposes a supporting device for the precise connection construction of super-heavy prefabricated columns, including a prefabricated column circumferential clamping component, which is clamped on the outside of the prefabricated column 1 and is not directly connected to the prefabricated column 1. In this embodiment, the middle and lower parts of the prefabricated column 1 are respectively clamped with a prefabricated column circumferential clamping component, and the upper and lower prefabricated column circumferential clamping components are connected by a fixing rod 7, and the fixing rod 7 is in contact with the side of the prefabricated column 1.

[0038] In this embodiment, the prefabricated column 1 is a rectangular parallelepiped structure.

[0039] The prefabricated column circumferential clamping component includes two first clamping members 3 arranged opposite to each other, and the two first clamping members 3 are respectively located on a group of opposite side surfaces of the prefabricated column 1. Clamping grooves are symmetrically provided on the left and right sides of the first clamping member 3, so that the first clamping member 3 is shaped like an I-beam, or like an "H" shape rotated 90°.

[0040] The prefabricated column circumferential clamping component also includes two second clamps 2 arranged opposite to each other, and the two second clamps 2 are respectively located on another set of opposite side surfaces of the prefabricated column 1. The width of the middle part of the second clamp 2 is greater than the width of its left and right ends, and the two ends of the second clamp 2 serve as plug-in parts. The two ends of the second clamp 2 are respectively inserted into and passed through the card slots on the adjacent first clamp 3, and the first clamp 3 and the second clamp 2 are tightly attached to the side surface of the prefabricated column 1. Connecting holes are provided at corresponding positions on the first clamp 3 and the second clamp 2, and the first clamp 3 and the second clamp 2 are connected by installing the clamp fixing pin 4 in the connecting hole, and the first clamp 3 and the second clamp 2 are clamped on the prefabricated column 1.

[0041] Specifically, the sizes of the first clamp 3 and the second clamp 2 are designed according to the size of the prefabricated column 1, the lengths of the first clamp 3 and the second clamp 2 are respectively greater than the widths of the sides of the prefabricated column 1 on which they are installed, and the opening positions of the connection holes on the first clamp 3 and the second clamp 2 are determined according to the size of the prefabricated column 1, so as to facilitate the subsequent installation of the clamp fixing pin 4. In this embodiment, the clamp fixing pin 4 passes through the upper half of the slot of the first clamp 3, the second clamp 2, and the lower half of the slot of the first clamp 3 in sequence, thereby connecting the first clamp 3 and the second clamp 2 together. After the connection is completed, the first clamp 3 and the second clamp 2 are just clamped on the outside of the prefabricated column 1 and will not fall off.

[0042] In this embodiment, the first clamping member 3 and the second clamping member 2 are steel clamping members.

When one end of the first supporting leg 5 is not connected to the prefabricated column circumferential clamping component, the first supporting leg 5 can rotate around the rotating seat 9 to adapt to the prefabricated column circumferential clamping components of different installation heights, and at the same time, replace the fixing rod 7 between the prefabricated column circumferential clamping components in the middle and lower parts of the prefabricated column 1, or use a telescopic rod for the fixing rod 7 to adapt to the prefabricated column circumferential clamping components of different installation heights.

[0044] A second supporting leg 10 is connected between the four sides of the prefabricated column circumferential clamping component located at the lower part of the prefabricated column 1 and the corresponding first supporting legs 5, respectively. The second supporting leg 10 is used to support the lower part of the prefabricated column 1, and one end of the second supporting leg 10 is fixed to the first clamping member 3 or the second clamping member 2 of the prefabricated column circumferential clamping component located at the lower part of the prefabricated column 1, and the other end of the second supporting leg 10 is connected to the rod portion of the first supporting leg 5 on the corresponding side.

[0045] The utility model forms a Y-shaped support structure composed of the first support leg 5 and the second support leg 10 on the four sides of the prefabricated column 1, which firmly supports the middle and lower parts of the prefabricated column 1 and ensures the stability of the prefabricated column 1.
