Description

Technical Field

[0001] This invention belongs to the field of steel structure installation technology, specifically, it relates to a quick-installation joint for steel structure beams and columns and its installation method. Background Technology

[0002] The existing production process for prefabricated steel structure buildings involves standardized design of building components, factory processing, and on-site assembly. This production method can reduce environmental pollution caused by construction, shorten the construction cycle, and save manpower and resources.

[0003] Chinese patent CN111021539B discloses an assembly method for a beam-column connection node of a steel structure cantilever beam. By welding an upper lap plate and a lower lap plate onto the steel structure column, the steel structure beam can be placed on the upper and lower lap plates, thereby providing a certain support for the steel structure beam and further transferring the pressure on the steel structure beam to the steel structure column. This improves the compressive and shear resistance of the steel structure beam and enhances the structural strength and stability of the beam-column connection node.

[0004] The existing technical solutions have the following drawbacks: after the quick-installation node is installed, it needs to be disassembled again if it needs to be adjusted horizontally. Sometimes it cannot reach the height desired by the workers and the corresponding steel beam needs to be disassembled and replaced, which wastes manpower and resources and increases the installation time of the workers.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a quick-installation joint for steel structure beams and columns and its installation method.

The fixing bracket is equipped with a mounting nut, and the mounting nut, the second connecting hole and the first connecting hole are on the same central axis. The second connecting hole is equipped with a mounting bolt, and the mounting bolt passes through the second connecting hole and the first connecting hole in sequence and is threaded onto the mounting nut.

[0013] Optionally, reinforcing plates are installed on both opposite sides of the bottom of the steel structure beam, and a fixing plate is installed on one side of the reinforcing plate. The fixing plate is threaded with reinforcing bolts, and the fixing plate and reinforcing bolts abut against the lower steel structure column. A first connecting column groove and a second connecting column groove are integrally formed on both sides of the steel structure beam. The second connecting plate is placed in the first connecting column groove, while the first connecting plate is located in the second connecting column groove. The mounting bolts pass through the second connecting hole and the first connecting hole in sequence, and the installation is fixed with mounting nuts.

[0014] Optionally, a second mounting plate is installed at the bottom of the upper steel structure column. The second mounting plate has a second mounting groove.

[0018] Step 3: Column connecting frame and beam connecting frame: Adjusting bolts are rotatably fitted on the column connecting frame, and threaded holes are opened on the beam connecting frame. The column connecting frame and beam connecting frame are assembled together by adjusting bolts and threaded holes.

[0019] Step 4: Beam connecting frame and steel structure beam: A first connecting plate and a second connecting plate are integrally formed on the beam connecting frame. A first connecting column groove and a second connecting column groove are integrally formed at both ends of the steel structure beam. The second connecting plate is placed in the first connecting column groove, while the first connecting plate is located in the second connecting column groove. The second connecting hole and the first connecting hole are sequentially passed through by the mounting bolts, and the installation is fixed by the mounting nuts.

[0020] Step 5: Column connecting frame and upper steel structure column: The bottom of the upper steel structure column is integrally formed with a second mounting plate and a second mounting groove. The limiting groove opened at the bottom of the upper steel structure column is fitted onto the threaded column. The fastening bolt passes through the second mounting groove and the mounting hole, and the fastening nut is used to fix the installation.

[0021] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art. Of course, any product implementing the present invention does not necessarily need to achieve all of the following advantages at the same time:

[0022] This quick-assembly steel beam-column joint allows for several adjustments. First, the beam connecting frame is installed on the lower steel column.
