Description

Technical Field

[0001] The present invention relates to the technical field of steel structure connection, in particular to a connection node structure between a steel beam and a steel pipe column. Background Art

[0002] With the continuous advancement of building industrialization, the application of steel structure prefabricated houses is becoming more and more extensive. The traditional commonly used connection node structures of steel beams and steel pipe columns are: 1. A stiffening plate is set at the position corresponding to the steel beam flange in the steel pipe column; 2. A through cross partition is set at the corresponding position of the steel pipe column and welded to the steel beam flange; 3. An outer ring stiffening plate is set on the steel pipe column to connect with the steel beam flange.

[0003] In residential buildings, to increase indoor usable area, the size of wall columns is minimized. However, joint structure type 1 is not suitable for smaller steel pipe columns. When the length and width of the steel pipe column are between 200 and 250 mm, it is difficult to install stiffening plates inside the steel pipe column. Joint structure type 2 requires multiple cuts of the steel pipe column, increasing the welding process and time. Both joint structures 2 and 3 have structures protruding from the outer surface of the steel pipe column, affecting the interior design. Therefore, a new joint structure is urgently needed. Summary of the Invention

[0004] The purpose of the present invention is to overcome the defects of the prior art and provide a connection node structure between steel beams and steel pipe columns to solve the problems of the existing connection nodes, such as difficulty in constructing stiffening plates when the steel pipe columns are small in size, structures protruding from the outer surface of the steel pipe columns affecting the indoor effect, and increasing the process and time.

[0005] The technical solution to achieve the above purpose is:

[0006] The present invention provides a connection node structure between a steel beam and a steel pipe column, comprising:

[0007] A variable-section column provided on the side of the steel pipe column corresponding to the steel beam, wherein the size of the side of the variable-section column connected to the steel pipe column is consistent with the size of the corresponding side of the steel pipe column, and the size of the side of the variable-section column connected to the steel pipe column is larger than the size of the other side of the variable-section column; and

[0008] The clamping sleeve is fixed on the variable-section column and is a connecting piece corresponding to the steel beam. The outer contour of the connecting piece is consistent with the outer contour of the steel beam, and the connecting piece is fixedly connected to the steel beam.

[0009] The connection node structure of the steel beam and the steel pipe column of the present invention utilizes a variable-section column and a connector provided on the side of the steel pipe column to connect to the steel beam. The provision of the variable-section column improves the structural rigidity of the side of the steel pipe column, and the connector is fixed to the variable-section column by a sleeve. The connection strength between the connector and the variable-section column is large, so there is no need to provide a stiffening plate in the steel pipe column, solving the problem of difficulty in constructing the stiffening plate due to the small size of the steel pipe column. Furthermore, the outer contour of the connector is consistent with the outer contour of the steel beam, and the side where the variable-section column is connected to the steel pipe column is consistent with the size of the steel pipe column, so that the node structure of the present invention has no structure protruding from the width of the column and will not affect the indoor effect. The steel beam and the connector are relatively connected, so that the force at the end of the steel beam can be evenly and effectively transmitted to the variable-section column and the steel pipe column, and the overall stability is good.

[0010] A further improvement of the connection node structure between the steel beam and the steel pipe column of the present invention is that the size of the variable-section column gradually increases from the side connected to the steel pipe column to the side connected to the connecting piece.

[0011] A further improvement of the connection node structure between the steel beam and the steel pipe column of the present invention is that a recess adapted to the shape of the variable-section column is provided on the side of the connecting piece connected to the variable-section column.

[0012] The further improvement of the connection node structure between the steel beam and the steel pipe column of the present invention is that:

[0013] A transverse bracing plate is provided inside the variable-section column. The transverse bracing plate is provided in the middle of the variable-section column and is fixedly connected to the corresponding side wall of the variable-section column.

[0014] The further improvement of the connection node structure between the steel beam and the steel pipe column of the present invention is that:

[0015] A concrete structure is poured into the variable-section column.

[0016] The further improvement of the connection node structure between the steel beam and the steel pipe column of the present invention is that:

[0017] A concrete structure is poured into the steel pipe column.

[0018] The further improvement of the connection node structure between the steel beam and the steel pipe column of the present invention is that:

[0019] The steel beam is an I-beam, and the connecting piece is an I-steel.

[0020] The further improvement of the connection node structure between the steel beam and the steel pipe column of the present invention is that:

[0021] The steel pipe column is a square column.

[0022] The further improvement of the connection node structure between the steel beam and the steel pipe column of the present invention is that:

[0031] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0032] See Figure 1 The present invention provides a connection node structure between steel beams and steel pipe columns, which is used to solve the problems existing in the traditional connection node structure between steel beams and steel pipe columns, such as difficulty in constructing stiffening plates when the steel pipe columns are small in size, structures protruding from the outer surface of the steel pipe columns affecting the interior effect, and increased processes and time. The connection node structure of the present invention provides a variable-section column on the side of the steel pipe column, so that the interior of the steel pipe column does not need to be provided with a stiffening plate, and the variable-section column is used to improve the rigidity of the steel pipe column. Moreover, the variable-section column and the connecting piece do not protrude from the column width range, which can ensure that the interior effect of the residence is not affected, thereby improving the applicability of the prefabricated residence. The structure of the connection node structure between the steel beams and steel pipe columns of the present invention is described below with reference to the accompanying drawings.

[0033] See Figure 1 , shows a structural diagram of the first embodiment of the connection node structure of the steel beam and the steel pipe column of the present invention. Figure 1 , the structure of the connection node structure between the steel beam and the steel pipe column of the present invention is explained.

[0034] like Figure 1 As shown, the connection node structure of the steel beam and the steel pipe column of the present invention includes a variable-section column 21 and a connector 22, which are used to connect the steel pipe column 11 and the steel beam 12; the variable-section column 21 is provided on the side of the steel pipe column 11 corresponding to the steel beam 12, and the size of the side of the variable-section column 21 connected to the steel pipe column 11 is consistent with the size of the corresponding side of the steel pipe column 11, and the size of the side of the variable-section column 21 connected to the steel pipe column is larger than the size of the other side of the variable-section column 21, so that after the variable-section column 21 is connected to the corresponding side of the steel pipe column 11, the variable-section column 21 has no structure protruding from the column width range of the steel pipe column, and will not affect the indoor effect. The connector 22 is fixed to the variable-section column 21 by a sleeve, and the connector 22 corresponds to the steel beam 12. The outer contour of the connector 22 is consistent with the outer contour of the steel beam 12, and the connector 22 is fixedly connected to the steel beam 12.

[0035] The connection node structure of the present invention uses a variable-section column and a connector to connect the steel pipe column and the steel beam, so that the node structure has no structure that protrudes from the column width range, and will not affect the indoor effect. In addition, the provision of the variable-section column increases the lateral stiffness of the steel pipe column, so that there is no need to set a stiffening plate inside the steel pipe column. The connector is fixedly connected to the variable-section column sleeve, which can evenly transfer stress to the variable-section column and then to the steel pipe column. The structure has strong force stability, and the contact area between the connector and the variable-section column is large, achieving a strong connection effect. The connection node structure of the present invention solves the problem of difficult construction of stiffening plates in steel pipe columns, and also ensures that the indoor effect of the residence is not affected, improves the applicability of steel structure prefabricated houses, and can further promote the development of the steel structure prefabricated house industry.

[0036] In a specific embodiment of the present invention, the size of the variable-section column 21 gradually increases from the side connected to the steel pipe column 11 to the side connected to the connector 22. The cross-section of the variable-section column 21 is tapered.

[0037] Furthermore, a recess that matches the shape of the variable-section column 21 is provided on one side of the connecting member 22 that is connected to the variable-section column 21. Preferably, the recess is in an inverted cone shape.

[0038] In a specific embodiment of the present invention, a cross brace 211 is provided inside the variable-section column 21 . The cross brace 211 is provided in the middle of the variable-section column 21 and fixedly connected to the corresponding side wall of the variable-section column 21 .

[0039] Before the variable-section column 21 is connected to the steel pipe column 11 , one side of the variable-section column 21 is open, and a cross brace can be conveniently provided in the variable-section column 21 through the open side.

[0040] In a specific embodiment of the present invention, a concrete structure 212 is poured into the variable-section column 21 .

[0041] In a specific embodiment of the present invention, a concrete structure 111 is poured into the steel pipe column 11 .

[0042] In a specific embodiment of the present invention, the steel beam 12 is an I-beam, and the connecting member 22 is an I-steel.

[0043] like Figure 2 and Figure 3 As shown, connecting plates and bolts are provided at the ends of the steel beam and the connecting piece. Part of the connecting plate is attached to the web of the connecting piece, and the other part is attached to the web of the steel beam. The connecting plates are provided on both sides of the web, and then the two connecting plates are fastened to the corresponding webs by bolts.

[0044] In a specific embodiment of the present invention, the steel pipe column 11 is a square column.

[0045] In one embodiment of the present invention, the variable-section column 21 is a steel column; the connector 22 is a steel component. The variable-section column 21 is welded to the steel pipe column 11, and the connector 22 is welded to the variable-section column 21 and the steel beam 12. Furthermore, the height of the variable-section column 21 is consistent with the height of the steel pipe column 11. Preferably, the steel pipe column is a hot-rolled or cold-expanded steel pipe. The variable-section column is formed by bending steel plate. The connector is a welded or hot-rolled steel component, and the connector and the steel beam are connected by bolt welding or full welding.

[0046] The weld between the variable cross-section column and the connector is increased, which can improve the connection strength between the two. The portion of the variable cross-section column not corresponding to the steel beam 12 is connected to the building wall, and the setting of the variable cross-section column improves the connection strength between the steel pipe column and the building wall.

[0047] like Figure 1 As shown in FIG, the first embodiment of the present invention is shown. In this first embodiment, the connection node structure of the present invention is applicable to L-shaped beam-column nodes, that is, the steel beam is located on both sides of the adjacent steel pipe column, and variable-section columns and connectors are provided on both sides of the adjacent steel pipe column. Figure 2 The second embodiment of the present invention is shown in the above. In this second embodiment, the connection node structure of the present invention is still applicable to L-shaped beam-column nodes. The difference from the first embodiment is that the number of steel pipe columns 11 is three, and the three steel pipe columns 11 are connected into an L shape, and then connected to the variable section column and the connector. Figure 4 As shown in FIG, a third embodiment of the present invention is shown. In this third embodiment, the connection node structure of the present invention is applicable to a T-shaped beam-column node, that is, the steel beam is located on three sides of the steel pipe column, and variable-section columns and connectors are provided on the three sides of the steel pipe column. Figure 5 As shown, the fourth embodiment of the present invention is shown. The difference between the fourth embodiment and the third embodiment is that the number of steel pipe columns 11 is four, and the four steel pipe columns are connected into a T-shape, and then connected to the variable cross-section column and the connecting piece. Figure 6 FIG. 5 shows a fifth embodiment of the present invention. In this fifth embodiment, the connection node of the present invention is a cross-shaped beam-column node, that is, the steel beam is located at the four sides of the steel pipe column, and variable-section columns and connectors are provided at the four sides of the steel pipe column. Figure 7 FIG. 6 shows a sixth embodiment of the present invention. This sixth embodiment differs from the fifth embodiment in that five steel pipe columns 11 are connected in a cross shape, and then connected to a variable-section column and a connector. The connection node structure of the present invention is also applicable to a straight-line beam-column joint, where the steel beams are located on opposite sides of the steel pipe column and connected to the steel beams via variable-section columns and connectors on the corresponding sides of the steel pipe column.
