Description

Technical Field

[0001] The present application relates to the field of steel structure installation, and more specifically, to a vertically welded positioning and fixing device for steel columns that can be reused. Background Art

[0002] The vertical welding positioning of steel columns mainly relies on welding temporary fixing ear plates on the steel columns during factory production for butt joint fixing. After the steel column welding is completed, the ear plates are discarded, resulting in significant waste. After the ear plates fix the steel column, it is difficult to adjust the position and perpendicularity of the steel column.

[0003] The prior art document with the publication (announcement) number of CN202222843652.4 provides a cross-shaped steel column butt joint installation positioning device. In the related technology of this device, installation slots are opened on two opposite side surfaces at the four ends of the positioning base plate, and the positioning clamping plates are fixed in the installation slots through screws and nuts. Relying on the cooperation between the positioning clamping plates and the installation slots, the butt joint installation of cross-shaped steel columns within a certain size range can be adapted.

[0004] Although the above prior art solution can achieve relevant beneficial effects through the structure of the prior art, there are still the following defects: it is only applicable to the installation of cross-shaped columns and cannot be reused.

[0005] In view of this, we propose a vertically welded positioning and fixing device for steel columns that can be reused. Summary of the Invention

[0006] In order to improve the problems proposed in the above background art, the present application provides a vertically welded positioning and fixing device for steel columns that can be reused.

[0007] The technical solution of the present invention is: a vertically welded positioning and fixing device for steel columns that can be reused, including:

[0008] Fixed clamping pieces. A total of four fixed clamping pieces are used in this device. Each clamping piece has a bolt hole at the upper part, two temporary fixing points welded by angle steel at the lower part, and two grooves are opened on the outer side of the fixed clamping piece.

[0009] Adjusting bolts. There are a total of twelve adjusting bolts in this device, with three as a group, installed on the bolt holes of the fixed clamping pieces.

[0010] Steel cables. After the temporary installation of the fixed clamping pieces is completed, reinforcement treatment is carried out with steel cables.

[0011] As a preferred solution of the vertically welded positioning and fixing device for steel columns that can be reused according to the present invention, among them: the fixed clamping piece is an L-shaped steel plate with a certain thickness, the upper part is narrower and has three bolt holes, the lower part is wider, and two temporary fixing points made of angle steel are provided on both sides.

[0012] As a preferred embodiment of the butt joint installation positioning device for the cruciform steel column of the present invention, the adjusting bolt is installed through the bolt hole of the fixing clip, with a rotating handle at one end for facilitating the adjustment of the bolt position and an enlarged fixing head at the other end for fixing the upper steel column.

[0013] As a preferred embodiment of the butt joint installation positioning device for the cruciform steel column of the present invention, the steel cable is installed and fixed through the groove on the fixing clip and is provided with a steel cable tightening device for tightening adjustment.

[0014] Advantages of the present invention:

[0015] 1. This device is a reusable mechanical device. Using this device for installing steel columns can reduce the use of ear plates, avoid material waste, and reduce costs.

[0016] 2. The unfixed steel column is fixed by the fixing clip, and the steel column is always in a constrained state during the adjustment process, ensuring construction safety.

[0017] 3. The adjustment of the steel column is carried out by using the adjusting bolt, which is simple and fast in operation and improves the construction efficiency. Description of the drawings
