Description

Technical Field

[0001] The utility model belongs to the technical field of steel structures, and in particular relates to a beam-column connection structure of a steel structure building. Background Art

[0002] Steel structure buildings are buildings that use construction steel to form a load-bearing structure. Usually, beams, columns, trusses and other components made of steel and steel plates form a load-bearing structure, and together with enclosure structures such as roofs, floors and walls, they form a complete building. Construction steel mainly includes hot-rolled angle steel, channel steel, I-beam, H-beam and steel pipes.

[0003] In existing steel structure buildings, the connection methods of steel structure columns and steel structure beams include welding, riveting, bolt connection, etc. When connecting the column and the H-shaped beam, the common method is to fix the T-shaped plate on the column, and then connect the T-shaped plate and the steel beam to complete the connection. However, the above structure does not have a buffering effect; when the beam is subjected to a large impact, such as a heavy object falling from the steel platform on the beam, the beam will deform, and the end of the beam will apply a force to the column, causing the column to deform or even break due to the lateral force, which poses a great safety hazard. Utility Model Content

[0004] In view of the above problems, the purpose of the utility model is to provide a beam-column connection structure for a steel structure building, so as to solve the problem that the existing connection structure between the column and the beam lacks a buffer mechanism, which will cause deformation and damage of the column when the beam is subjected to a large impact.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is: a beam-column connection structure of a steel structure building, including a buffer connection piece, the buffer connection piece includes a column connection section, a beam connection section is welded on the column connection section, the beam connection section is connected to the H-shaped beam by bolts, the column connection section is connected to a spring plate by clamping bolts, the two ends of the spring plate slide against the anti-wear plate, the anti-wear plate is installed on the column, the two ends of the column connection section are provided with slots adapted to install positioning pieces, and the bolts inserted in the positioning pieces are fixed to the column.

[0006] The beneficial effects of the utility model are as follows: the spring plate in the buffer connector can play a role of elastic buffering when the H-shaped beam is deformed by impact force, thereby preventing the H-shaped beam from being deformed and damaged when it is subjected to a large impact; the anti-wear plate can effectively protect the surface of the column.

[0007] In order to make the spring plate play the role of stable elastic support;

[0008] As a further improvement of the above technical solution: the number of the clamping bolts is multiple and they are relatively arranged on both sides of the beam connecting section.

[0011] As a further improvement of the above technical solution: the anti-wear plate includes a plate body, and the width of the plate body is not less than the width of the spring plate.

[0012] The beneficial effect of this improvement is that the plate body plays the role of supporting the spring plate, withstands the force exerted by the repeated movement and squeezing of the end portion of the spring plate when it is deformed, and effectively protects the surface of the column.

[0013] In order to prevent the deformation of the spring plate from exceeding the elastic travel range;

[0014] As a further improvement of the above technical solution: two limit blocks are arranged on the plate body in an upper and lower direction opposite to each other, and the limit blocks are arranged on the outer side of the spring plate.

[0015] The beneficial effect of this improvement is that the limit block plays a limiting role, preventing the end of the spring plate from moving beyond the stroke, thereby causing the deformation of the spring plate to exceed the elastic stroke range and cause damage.

[0016] In order to ensure the stability of the connection between the buffer connector and the column;

[0017] As a further improvement of the above technical solution: the column connecting section is a channel steel structure, and the flanges of the column connecting section fit the two sides of the connecting column.

[0019] In order to ensure the stability of the installation of the buffer connector;

[0020] As a further improvement of the above technical solution: the positioning member is a circular ring structure, and arc plate structures are arranged on the positioning member at intervals.

[0021] The beneficial effect of this improvement is that the positioning piece plays a positioning role to ensure the stability of the installation of the column connecting section on the column.

[0032] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention is described in detail below in conjunction with the accompanying drawings. The description in this part is only exemplary and explanatory and should not have any limiting effect on the protection scope of the present invention.

[0033] Embodiment 1:

[0034] like Figure 1—5 shows: a beam-column connection structure of a steel structure building, including a buffer connection member 3, the buffer connection member 3 includes a column connection section 31, a beam connection section 35 is welded on the column connection section 31, the beam connection section 35 is connected to the H-shaped beam 2 by bolts, the column connection section 31 is connected to a spring plate 34 by clamping bolts 33, the two ends of the spring plate 34 slide against the anti-wear plate 4, the anti-wear plate 4 is installed on the column 1, the two ends of the column connection section 31 are provided with slots adapted to install the positioning member 32, the positioning member 32 is inserted The bolts installed are fixed on the column 1. The spring plate 34 in the buffer connector 3 can play an elastic buffering role when the H-shaped beam 2 is deformed by the impact force, so as to avoid deformation and damage of the column 1 when the H-shaped beam 2 is subjected to a large impact; the anti-wear plate 4 can effectively protect the surface of the column 1. The number of the clamping bolts 33 is multiple, and they are relatively arranged on both sides of the beam connecting section 35. The multiple symmetrically arranged clamping bolts 33 can stably fix the spring plate 34 on the column connecting section 31 to ensure the stability of the spring plate 34 support. The anti-wear plate 4 includes a plate body 41 The width of the plate body 41 is not less than the width of the spring plate 34. The plate body 41 supports the spring plate 34 and bears the force exerted by the repeated movement and extrusion of the end of the spring plate 34 when it is deformed, effectively protecting the surface of the column 1. Two limit blocks 42 are arranged on the plate body 41 in an upper and lower direction. The limit blocks 42 are arranged on the outer side of the spring plate 34. The limit blocks 42 play a limiting role to prevent the end of the spring plate 34 from moving beyond the stroke, thereby causing the deformation of the spring plate 34 to exceed the elastic stroke range and be damaged. The column connecting section 31 is a channel steel structure. The column connecting section 31 The flange fits the two sides of the connecting column 1, and the column connecting section 31 can be stably connected to the column 1 under the cooperation of the flange and the bolts. The positioning member 32 is a circular ring structure, and the positioning member 32 is provided with an arc plate structure at intervals. The positioning member 32 plays a positioning role to ensure the stability of the column connecting section 31 installed on the column 1. The beam connecting section 35 is relatively arranged on both sides of the web of the H-shaped beam 2. The beam connecting section 35 can be stably connected to the web of the H-shaped beam 2 by welding or bolts, thereby ensuring the stability of the connection between the buffer connector 3 and the H-shaped beam 2.

[0035] The working principle of this technical solution is as follows: first, the wear plate 4 is installed, and the wear plate 4 is fixed to the side of the column 1 where the H-shaped beam 2 needs to be installed by welding or bolting. Then the column connecting section 31 is mounted on the outside of the column 1 and the wear plate 4, and the bolts are inserted into the inner side of the positioning piece 32. After tightening the nuts, the column 1 and the buffer connecting piece 3 are connected, and finally the H-shaped beam 2 and the beam connecting section 35 are connected by bolts. When the H-shaped beam 2 is subjected to impact force and elastic deformation occurs, the distance between the two ends of the H-shaped beam 2 relative to the column 1 changes, and the H-shaped beam 2 drives the beam connecting section 35 to move, and the beam connecting section 35 drives the column connecting section 31 to move. The bottom end of the spring plate 34 fixed by the clamping bolts 33 on the column connecting section 31 is supported and squeezed by the wear plate 4 to produce elastic deformation, which plays a role in buffering and energy absorption, thereby avoiding structural damage caused by the rigid connection between the H-shaped beam 2 and the column 1.
