Description

Technical Field

[0001] This utility model relates to the field of steel structure frame technology, specifically a steel structure frame splicing node structure. Background Technology

[0002] Steel frame splicing joint structure refers to the connection parts and related structures in a steel frame used to connect various components (such as beams and columns) so that they can work together to jointly bear the structural load.

[0003] These node structures connect the various components of the steel structure through welding, bolting, or a combination of bolting and welding. They not only transmit forces and moments but also ensure the integrity, stability, and reliability of the structure to meet the requirements of the steel frame under various loads.

[0004] The existing patent application publication number CN115478610A discloses an assembly structure for a steel frame node, including columns and beams. The column has a connecting part that can be inserted into the beam, and one end of the beam has a mating part that can be inserted into the connecting part. The connecting part includes an insertion part and a fixing part connected to the insertion part on the side away from the column. This technical solution, through the assembly structure between the connecting part and the mating part, not only enables the steel frame node to have good connection strength but also extremely high stability after assembly. However, it lacks components for lateral connection and extension of the channel steel beam, affecting the flexibility of the steel frame splicing node structure. Utility Model Content

[0005] To address the above problems, the purpose of this utility model is to provide a steel structure frame splicing node structure that solves the problem of lacking components for lateral connection and extension of channel steel beams, which affects the flexibility of the steel structure frame splicing node structure. After completing the connection between the main body of the steel beam and the box column, the main body of the steel beam is laterally extended according to the usage requirements. The second main body of the steel beam is attached to the end of the first main body of the steel beam away from the box column. Then, two mating folding plates are placed stably on the inner side of the connection between the two main bodies of the steel beams and initially connected with bolts. Next, two mating horizontal plates are symmetrically placed at the upper and lower ends of the connection between the two main bodies of the steel beams and connected in the second step with bolts.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a steel structure frame splicing node structure, comprising a steel structure component, a steel beam component, and a node component. The steel structure component includes a box-shaped column and a connecting side plate. The steel beam component includes a steel beam body, a mating folding plate, and a mating cross plate. The node component includes a fitting back plate. Side wing plates are symmetrically connected to both ends of the steel beam body. A connecting plate is connected to one end of the steel beam body. An insert inner plate is connected to the end of the connecting plate away from the steel beam body. Maturing folding plates are symmetrically connected to the upper and lower ends of the connecting plate. Side upright plates are symmetrically connected to both ends of the fitting back plate. A folded edge plate is connected to the end of the side upright plate away from the fitting back plate. A protective edge side plate is provided at the end of the folded edge plate away from the side upright plate. An installation groove is provided on the inner side of the fitting back plate.

[0007] The beneficial effects of this utility model are as follows: After completing the connection between the main body of the steel beam and the box column, the main body of the steel beam is extended laterally according to the needs of use. The second main body of the steel beam is attached to the end of the first main body of the steel beam away from the box column. Then, the two mating folding plates are placed stably on the inner side of the connection between the two main bodies of the steel beam and the bolts are used for initial connection. Then, the two mating horizontal plates are placed symmetrically at the upper and lower ends of the connection between the two main bodies of the steel beam and the bolts are used for the second step of connection.

[0008] To ensure a proper fit between the two adjacent right-angled sides of the box-shaped column and one right-angled side of the connecting side plate, and to secure the connecting side plate to the right-angled side of the box-shaped column, a full penetration weld is then performed between the box-shaped column and the connecting side plate:

[0009] As a further improvement to the above technical solution: the box-shaped column is a hollow steel pipe with a rectangular structure, the connecting side plate is a T-shaped steel plate, and the connecting side plates are arranged in pairs.

[0010] The beneficial effects of this improvement are as follows: In use, the two adjacent right-angled sides of the box column are fitted with one right-angled side of the connecting side plate, and the connecting side plate is snapped onto the right-angled side of the box column. Then, the box column and the connecting side plate are fully penetrated welded, and the connecting side plates of the same group are symmetrically welded on both sides of the outer wall of the box column. After welding, the weld should be inspected to ensure the welding quality.

[0011] For connection with the folded edge plate, and thus for connection between the folded edge plate and the box column:

[0012] As a further improvement to the above technical solution: a first bolt hole is provided on the inner side of the connecting side plate, and the first bolt hole is provided at equal intervals along the height direction of the connecting side plate.

[0013] The beneficial effects of this improvement are: the opening of the first bolt hole is used to connect with the folded edge plate, thereby realizing the connection between the folded edge plate and the box column.

[0014] To ensure that the side panels at both ends of the back panel are fitted to the two connecting side panels, an inner groove is provided for inserting the inner panel:

[0015] As a further improvement to the above technical solution: the back plate and the side upright plate are integrally formed, and the mounting groove is a through-hole groove with a rectangular structure.

[0016] The beneficial effects of this improvement are as follows: After completing the connection of the two connecting side plates of the same group to the two side walls of the box column, the backing plate is attached to the outer wall of the box column, and the side uprights at both ends of the backing plate are attached to the two connecting side plates respectively. The inner groove is installed to accommodate the groove into which the inner plate is inserted.

[0017] The purpose of installing side guards is to protect the side wing panels and thus prevent them from being damaged in impacts.

[0018] As a further improvement to the above technical solution: the height of the side upright is the same as the height of the back panel, the two side guards are symmetrically arranged, and the side guards and the folded edge plate are integrally formed.

[0019] The beneficial effects of this improvement are as follows: the side uprights are used to fit against the side of the connecting side plate, and the side guards are used to protect the side wing plates, thereby preventing the side wing plates from being hit. At the same time, a 2mm gap is reserved between the side guards and the side wing plates to prevent thermal expansion and contraction from affecting the structure.

[0020] To ensure a stable connection between the two connecting side panels via node components, thereby guaranteeing the stability of the connecting side panels during use:

[0021] As a further improvement to the above technical solution: the top view cross-section of the folded edge plate is set with an L-shaped structure, and a third bolt hole is opened on the inner side of the folded edge plate.

[0022] The beneficial effects of this improvement are as follows: after the backing plate is bonded to the outer wall of the box column, the folded edge plate is simultaneously bonded to the adjacent connecting side plate. Then, through full penetration welding, the backing plate is connected to the box column. Then, bolts are used to connect the folded edge plate to the adjacent connecting side plate. Thus, the node component is connected to the box column at the same time as the connecting side plate. At the same time, the two connecting side plates form a stable connection through the node component, thereby ensuring the stability of the connecting side plate during use.

[0023] To achieve the connection between the steel beam assembly and the node assembly, and thus the connection between the steel structure assembly, the steel beam assembly, and the node assembly:

[0024] As a further improvement to the above technical solution: the main body of the steel beam is an I-beam, one end of the side wing plate is set with an arc structure, and each main body of the steel beam is connected to four side wing plates at the same time.

[0025] The beneficial effects of this improvement are as follows: by setting the side wing plate, the end face of the main body of the steel beam is extended. At the same time, the side wing plate and the edge guard plate are fully penetrated by welding. After welding, the weld should be inspected for flaws to ensure the welding quality. This realizes the connection between the steel beam assembly and the node assembly, and then realizes the connection between the steel structure assembly, the steel beam assembly and the node assembly.

[0026] To ensure the stability of the connection between the two steel beams, the two mating cross plates are symmetrically placed at the top and bottom ends of the connection point. Bolts are also used for the second step of the connection, thus ensuring the stability of the connection between the two steel beams.

[0027] As a further improvement to the above technical solution: a second bolt hole is provided on the inner side of the mating folding plate, the length of the mating horizontal plate is the same as the transverse width of the main body of the steel beam, and a second bolt hole is symmetrically provided on the inner side of the mating horizontal plate.

[0028] The beneficial effects of this improvement are as follows: After completing the connection between the main body of the steel beam and the box column, the main body of the steel beam is extended laterally according to the usage requirements. The second main body of the steel beam is attached to the end of the first main body of the steel beam away from the box column. Then, the two mating folding plates are placed stably on the inner side of the connection between the two main bodies of the steel beam and the initial connection is made with bolts. Next, the two mating horizontal plates are placed symmetrically at the upper and lower ends of the connection between the two main bodies of the steel beam and the second step of connection is made with bolts, thereby ensuring the stability of the connection between the two main bodies of the steel beam.

A protective edge plate 35 is provided at the end of the folded edge plate 33 away from the side upright plate 32. An inner mounting groove 36 is provided on the inner side of the back panel 31. The box-shaped column 11 is a rectangular hollow steel pipe, and the connecting side plate 12 is a T-shaped steel plate. Two connecting side plates 12 form a group. In use, two adjacent right-angled sides of the box-shaped column 11 are fitted with one right-angled side of the connecting side plate 12, and the connecting side plate 12 is snapped onto the right-angled side of the box-shaped column 11. Then, the box-shaped column 11 and the connecting side plate 12 are fully penetrated welded, and the connecting side plates 12 in the same group are symmetrically welded to both sides of the outer wall of the box-shaped column 11. After welding, the weld should be inspected for defects. To ensure welding quality, the inner side of the connecting side plate 12 is provided with first bolt holes 13, which are evenly spaced longitudinally along the height direction of the connecting side plate 12.

At the same time, the two connecting side plates 12 form a stable connection through the node assembly 3, ensuring the stability of the connecting side plates 12 during use. The main body of the steel beam 21 is an I-beam, and one end of the side flange 22 has an arc-shaped structure. Each main body of the steel beam 21 is simultaneously connected to four side flanges 22. The side flanges 22 are used to extend the end face of the main body of the steel beam 21. Simultaneously, through full penetration welding of the side flanges 22 and the edge guard plate 35, the weld should be inspected for flaws after welding to ensure the weld quality.
