Description

Technical Field

[0001] The present invention relates to the technical field of building construction, and particularly relates to a joint connection structure for prefabricated steel structure buildings. Background Art

[0002] For prefabricated steel structure buildings, some or all of the building components can be produced in a component prefabrication factory and then transported to the construction site by corresponding transportation means, and the components are assembled using reliable installation methods and installation machinery. Safety and reliability, and improved work efficiency are the greatest advantages of prefabricated steel structures. However, there are still many problems in the existing prefabricated steel structure industry. The joint connections between columns and columns, and between beams and columns require welding connections, which seriously affect the construction efficiency of prefabricated steel structure buildings. Moreover, due to the relatively high position of the connection nodes, the risk during the welding process is relatively high. Summary of the Invention

[0003] In order to solve the problem that the joint connections between columns and columns, and between beams and columns in prefabricated steel structure buildings in the prior art require welding connections, the present invention provides a joint connection structure for prefabricated steel structure buildings. This structure does not require node welding, improving work efficiency and safety.

[0004] To achieve the above object, the technical solution of the present invention is as follows:

[0005] A joint connection structure for prefabricated steel structure buildings includes an upper column section and a lower column section. The lower column section is located below the upper column section. A connecting plate is provided at the bottom of the upper column section. A clamping block is provided on the bottom surface of the connecting plate. A connecting column sleeve is connected below the connecting plate. The connecting column sleeve is sleeved on the top end of the lower column section. A connecting top plate is provided at the top of the connecting column sleeve and is connected to the connecting plate. A lower column card slot and a column sleeve card slot are respectively opened at the top of the lower column section and the connecting column sleeve. The positions of the lower column card slot and the column sleeve card slot overlap and their shapes are matched with the clamping block.

[0006] A cross beam is provided on one side of the lower column section. First connecting clamping plates are provided at both ends of the cross beam. Upper cross beam clamping plates and lower cross beam clamping plates are respectively connected to both sides of the first connecting clamping plate. The lower cross beam clamping plate is fixed on one side of the lower column section. Components of the connecting column section do not adopt on-site welding forms and there are no on-site cast-in-place nodes. Each component can be produced in the factory and only needs to be assembled on-site during use, without considering the influence caused by welding, and the construction quality is easier to guarantee.

[0007] Further, connecting holes are correspondingly opened in the connecting plate and the connecting top plate. A column connection clamping member is provided at the connecting holes. The column connection clamping member is located at the end corners and sides of the connecting plate and clamps the connecting plate and the connecting top plate together. Through holes are opened at the positions corresponding to the connecting holes of the column connection clamping member for bolt connection. After clamping the connecting plate and the connecting top plate with the column connection clamping member and then using bolt connection, the connection structure is made more firm.

[0008] Furthermore, the column connection fasteners located at the end corners are wrapped around the end corners in a surrounding shape, and the column connection fasteners located on the sides are in a "U" shape, and the connecting plate and the connecting top plate are clamped between the two vertical plates of the "U" shape.

[0009] Furthermore, the cross-section of the clamping block is triangular, and the apex angle of the clamping block is connected to the connecting plate. The connection is made more secure by the cooperation of the clamping block and the clamping groove.

[0010] Furthermore, a bolt is provided on one side of the connecting column sleeve to penetrate through the connecting column sleeve and the lower column section for connection. The connection is more secure by the bolt penetrating through the connecting column sleeve and the lower column section.

[0011] Furthermore, the cross beam is in an I shape, the upper cross beam clamping plate (6) is in a "T" shape, and the lower cross beam clamping plate (7) is in an inverted "T" shape.

[0012] Furthermore, a clamping plate clamping groove is formed on the side of the connecting column sleeve, and the vertical plate of the lower cross beam clamping plate is located in the clamping plate clamping groove.

[0013] Furthermore, the first connecting clamping plate is connected to the vertical plate of the cross beam and is located between the vertical plates of the upper cross beam clamping plate and the lower cross beam clamping plate. The first connecting clamping plate, the vertical plates of the cross beam clamping plates and the vertical plate of the lower cross beam clamping plate are connected by bolts penetrating through.

[0014] Furthermore, the horizontal plates of the upper cross beam clamping plate and the lower cross beam clamping plate are respectively located on one side of the two horizontal plates of the cross beam and are attached to each other. Beam connection fasteners are provided on both sides of the attachment part. Second connecting clamping plates are respectively provided at both ends of the beam connection fastener. The second connecting clamping plate located above clamps the upper horizontal plate of the cross beam and the horizontal plate of the upper cross beam clamping plate, and the second connecting clamping plate located below clamps the lower horizontal plate of the cross beam and the horizontal plate of the lower cross beam clamping plate. Bolts are provided on the beam connection fastener to penetrate through and connect the second connecting clamping plate, the upper cross beam clamping plate, the lower cross beam clamping plate and the cross beam.

[0015] Furthermore, stiffening ribs are provided above the connecting plate, below the connecting top plate and below the lower cross beam clamping plate. The structural strength of the connection part is improved by the stiffening ribs.

[0016] By the above technical solutions, the beneficial effects of the present invention are as follows:

[0017] 1. None of the components of the connecting column section of the present invention adopt the form of on-site welding, and there are no on-site cast-in-place joints. Each component can be produced in a factory and only needs to be assembled on-site during use, without considering the influence caused by welding, and the construction quality is easier to be guaranteed.

[0018] 2. All the connection parts of the present invention adopt splicing and are fixed by bolts, which is more environmentally friendly and more convenient for recycling. The components do not adopt the form of welding, avoiding the influence caused by weather conditions and improving work efficiency.

[0019] 3. The present invention increases the effective area of the column section connection by using a connecting column sleeve, effectively solving the problem of small connection cross-sections between column sections. The additional column connection fasteners further enable it to better form an integral whole, bear the horizontal force at the connection node, enhance the reliability of the connection, and make the performance safer and more reliable.

[0020] 4. The connection of the column sections in the present invention is achieved by the blocks below the connecting plate being horizontally slid into connection with the lower column section and the connecting column sleeve. This allows for the free replacement of beams or columns with problems in the system without being affected by the upper components. BRIEF DESCRIPTION OF THE DRAWINGS
