Description

Technical Field

[0001] The invention relates to a steel frame structure that can be quickly assembled and disassembled and reused, and belongs to the technical field of building industrialization and assembled frame structure construction. Background Art

[0002] Modern buildings can be mainly divided into the following four categories: 1. Brick-wood structure; 2. Brick-concrete structure; 3. Steel-concrete structure; 4. Steel structure. Steel structure is a structure mainly composed of steel materials, one of the main types of building structures. Steel structure is mainly composed of steel beams, steel columns, steel bridge frames and other components made of steel and steel plates. The components or parts are usually connected by welding welds, bolts or rivets. In the process of steel structure connection, the main role is played by steel beams and columns, which are the main body of the entire steel structure frame building. Compared with traditional concrete buildings, steel structure buildings use steel plates or steel to replace reinforced concrete, which has higher strength and better earthquake resistance. And because the components can be factory-made and installed on-site, the construction period is greatly reduced. Due to the reusability of steel, it can greatly reduce construction waste and be more green and environmentally friendly, so it is widely used in industrial and civil buildings. In the prior art, large-span steel beams are prone to flexural deformation and collapse and bending in the middle section after long-term use due to their long length and heavy weight. After the middle section of the steel beam collapses and bends, due to the deformation of the steel beam, the tensile force along the direction of the steel beam applied by the end of the steel beam to the steel structure column increases. A gap is easily generated at the connection between the steel structure column and the end of the steel beam, causing the bolt connection to loosen, affecting the stability of the steel structure. Summary of the invention

[0003] In order to solve the problems of collapse and bending of the middle section of steel beams and poor stability of connection nodes of frame structures, the present invention provides a steel frame structure that can be quickly assembled and disassembled and reused.

[0012] Furthermore, the vertical support is composed of a fixed sleeve, a support rod, and a fixed foot. The fixed sleeve is a hollow cylinder, and its inner diameter matches the outer diameter of the circular arch support frame. Two support rods are prefabricated on the upper side of the fixed sleeve. The length of the two support rods can be adjusted according to the distance between the circular arch support frame and the main beam. A fixed foot is arranged on the upper end of the support rod, and the fixed foot is connected to the lower flange of the main beam by connecting bolts.

[0013] Furthermore, the left and right ends of the round arch support frame are inserted into the round arch support mounting grooves, and the round arch support frame is fixed on the fixing sleeve.

[0014] Furthermore, the L-shaped support frame consists of a long limb and a short limb, the short limb is arranged on the lower side of the long limb, the long limb is tightly attached to the positioning plates under the main beam mounting groove and the side beam mounting groove, and the short limb is fixed to the H-shaped steel column by connecting bolts.
