Description

Technical Field

[0001] This utility model relates to the field of steel component connection technology, specifically a steel column and steel beam connector. Background Technology

[0002] Steel structures are structures made of steel materials and are mainly used in construction. Steel is lightweight, easy to construct, and generally has good corrosion resistance after rust removal and prevention treatments. Steel structures mainly include steel beams, steel columns, and steel trusses.

[0003] In existing technologies, steel structures typically use steel columns and steel beams. The steel columns are vertically placed on the ground, and the steel beams are connected to the steel columns through the combination of L-shaped connecting plates and bolts.

[0004] Regarding the aforementioned technologies, steel columns and beams are typically connected only by L-shaped connecting plates and bolts. Although this is convenient for installation, the load-bearing capacity of the L-shaped connecting plates is extremely limited. In particular, when the I-beam needs to withstand a large bending moment, the bending moment will act on the L-shaped connecting plate through the flange of the I-beam, which poses a greater risk of deformation and fracture. This results in poor structural connection stability or structural strength between the steel column and the I-beam. Utility Model Content

[0005] To overcome the shortcomings of the existing technology, this utility model provides a steel column and steel beam connector.

[0006] The present invention adopts the following technical solution: A steel column-beam connector is used to structurally connect a steel column and an I-beam, the steel column-beam connector comprising: The fixed base includes an integrally connected force-bearing ring and positioning side plate. The force-bearing ring is sleeved on the column-shaped steel column. Both the force-bearing ring and the positioning side plate are fixedly connected to the column-shaped steel column by multiple screws or bolts. The connecting assembly protrudes from the side of the positioning side plate away from the column-shaped steel column. The connecting assembly includes an upper fastening plate and a lower fastening plate arranged opposite each other, and two intermediate fastening plates arranged opposite each other. The two intermediate fastening plates are located between the upper fastening plate and the lower fastening plate. The upper fastening plate, the two intermediate fastening plates and the lower fastening plate together form an I-beam slot adapted to the I-beam. During installation, the I-beam is inserted into the I-beam slot and fixedly connected to the upper fastening plate, the two intermediate fastening plates, and the lower fastening plate by multiple high-strength bolts.

[0007] In one embodiment, a plurality of the screws or bolts are distributed around the force-bearing ring.

[0008] In one embodiment, the force-bearing ring is perpendicular to the positioning side plate.

[0009] In one embodiment, the connecting assembly further includes two C-shaped fastening blocks, which are symmetrically arranged on both sides of the upper fastening plate. Each C-shaped fastening block has a clamping opening for clamping the upper fastening plate and the upper flange of the I-beam, so that the corresponding high-strength bolts are sequentially passed through the upper end of the C-shaped fastening block, the upper fastening plate, the upper flange of the I-beam, and the lower end of the C-shaped fastening block before being tightened.

[0010] In one embodiment, both of the C-shaped fastening blocks are integrally formed structural components.

[0011] In one embodiment, the upper fastening plate has a first reinforcing rib on the side opposite to the I-beam slot, and the lower fastening plate has a second reinforcing rib on the side opposite to the I-beam slot.

[0012] In one embodiment, the height of the upper fastening plate and the two intermediate fastening plates is greater than the height of the lower fastening plate.

[0013] In one embodiment, the fixing base and the connecting assembly are integrally connected structures.

[0014] In one embodiment, the upper end face of the positioning side plate is provided with a first welding roughness near the column-shaped steel column, and the column-shaped steel column is provided with a second welding roughness corresponding to the first welding roughness, and the first welding roughness and the second welding roughness are connected to each other.

[0015] In one embodiment, the depth of the first weld roughness ranges from 3 mm to 5 mm; the depth of the second weld roughness ranges from 1 mm to 3 mm.

[0016] The beneficial effects of this utility model are as follows: This utility model ensures the structural connection stability between the fixed base and the column by fitting a force-bearing ring sleeve onto the column and fixing the force-bearing ring sleeve and positioning side plate to the column using multiple screws or bolts. Because the connecting assembly protrudes from the positioning side plate on the side opposite to the column, and the upper fastening plate, two intermediate fastening plates, and lower fastening plate together form an I-beam slot adapted to the I-beam, during installation, the I-beam can be first inserted into the I-beam slot, and then fixed to the upper fastening plate, two intermediate fastening plates, and lower fastening plate respectively using multiple high-strength bolts. This achieves horizontal fastening of the upper and lower flanges of the I-beam and vertical fastening of the web of the I-beam, thus replacing the traditional L-shaped connecting plate and providing better structural connection stability and strength between the column and the I-beam.

Detailed Implementation

[0019] The accompanying drawings are for illustrative purposes only and should not be construed as limiting the scope of this patent. To better illustrate this embodiment, some parts in the drawings may be omitted, enlarged, or reduced, and do not represent the actual dimensions of the product.

[0020] It will be understood by those skilled in the art that certain well-known structures and their descriptions may be omitted in the accompanying drawings. The technical solution of this utility model will be further described below with reference to the accompanying drawings and embodiments.

[0021] Please refer to the instruction manual appendix as well. Figure 1-4 As shown, this utility model provides a steel column and steel beam connector for structurally connecting a column-shaped steel column 10 with an I-beam 20. A steel column and steel beam connector includes a fixing base 100 and a connecting assembly 200. The fixing base 100 includes an integrally connected force-bearing ring 110 and a positioning side plate 120. The force-bearing ring 110 is sleeved on the column-shaped steel column 10. The force-bearing ring 110 and the positioning side plate 120 are both fixedly connected to the column-shaped steel column 10 by multiple screws or bolts. The connecting assembly 200 protrudes from the side of the positioning side plate 120 away from the column-shaped steel column 10. The connecting assembly 200 includes an upper fastening plate 210 and a lower fastening plate 220 arranged opposite to each other, and two intermediate fastening plates 230 arranged opposite to each other. The two intermediate fastening plates 230 are located between the upper fastening plate 210 and the lower fastening plate 220. The upper fastening plate 210, the two intermediate fastening plates 230 and the lower fastening plate 220 together form an I-beam slot 201 adapted to the I-beam 20.

[0022] During installation, the I-beam 20 is inserted into the I-beam slot 201 and fixedly connected to the upper fastening plate 210, the two intermediate fastening plates 230 and the lower fastening plate 220 respectively by multiple high-strength bolts.

[0023] In this embodiment, the present invention ensures the structural connection stability between the fixed base 100 and the column steel column 10 by fitting the force-bearing ring 110 onto the column steel column 10 and fixing the force-bearing ring 110 and the positioning side plate 120 to the column steel column 10 using multiple screws or bolts; and because the connecting assembly 200 protrudes from the side of the positioning side plate 120 away from the column steel column 10, the upper fastening plate 210, the two intermediate fastening plates 230 and the lower fastening plate 220 together form a structure adapted to the I-beam 20. The I-beam slot 201 allows the I-beam 20 to be inserted into the slot 201 during installation. Then, multiple high-strength bolts are used to fix the I-beam 20 to the upper fastening plate 210, the two intermediate fastening plates 230, and the lower fastening plate 220, respectively. This achieves horizontal fastening of the upper and lower flanges of the I-beam 20 and vertical fastening of the web of the I-beam 20, thus replacing the traditional L-shaped connecting plate and improving the structural connection stability and structural strength between the column 10 and the I-beam 20.

[0024] like Figure 1As shown, preferably, multiple screws or bolts are distributed around the force-bearing ring 110 to lock and fix the force-bearing ring 110 to the outer peripheral wall of the column steel column 10, so as to ensure the reliability of the fixed connection between the positioning side plate 120 and the column steel column 10 after they are attached, that is, to ensure the structural connection stability of the fixed base 100.

[0025] like Figure 1 As shown, the force-bearing ring 110 is preferably perpendicular to the positioning side plate 120.

[0026] like Figures 1 to 3 As shown, the connecting assembly 200 preferably includes two C-shaped fastening blocks 240. The two C-shaped fastening blocks 240 are symmetrically arranged on both sides of the upper fastening plate 210. Each C-shaped fastening block 240 has a clamping opening 2401, which is used to clamp the upper fastening plate 210 and the upper flange of the I-beam 20, so that the corresponding high-strength bolts are tightened after passing through the upper end of the C-shaped fastening block 240, the upper fastening plate 210, the upper flange of the I-beam 20 and the lower end of the C-shaped fastening block 240 in sequence. It is understandable that by adding a C-type fastening clamp 240, the upper fastening plate 210 and the upper flange of the I-beam 20 are clamped and fixed using the clamp 2401. Then, high-strength bolts are used to fix the C-type fastening clamp 240, the upper fastening plate 210 and the I-beam 20 together. This effectively reduces the risk of deformation and fracture of the upper fastening plate 210 and improves the structural connection stability and structural strength of the column 10 and the I-beam 20.

[0027] like Figures 1 to 3 As shown, preferably, both C-type fastening blocks 240 are integrally formed structural parts to ensure that the C-type fastening blocks 240 have good structural strength.

[0028] like Figure 1 , Figure 3 and Figure 4 As shown, the upper fastening plate 210 is provided with a first reinforcing rib 2110 on the side opposite to the I-beam slot 201, and the lower fastening plate 220 is provided with a second reinforcing rib 2210 on the side opposite to the I-beam slot 201, so as to ensure the structural strength of the upper fastening plate 210 and the lower fastening plate 220.

[0029] like Figure 1 , Figure 3 and Figure 4As shown, the height of the upper fastening plate 210 and the two intermediate fastening plates 230 is greater than the height of the lower fastening plate 220. Specifically, this makes the structural strength of the upper fastening plate 210 and the intermediate fastening plates 230 greater, thereby increasing the upper limit of the load on the upper fastening plate 210 and the intermediate fastening plates 230. In this way, when the end of the I-beam 20 away from the positioning side plate 120 is subjected to a large bending moment, the risk of deformation and fracture of the upper fastening plate 210 and the intermediate fastening plates 230 is smaller, thereby improving the structural connection stability and structural strength between the column steel column 10 and the I-beam 20.

[0030] like Figure 1 As shown, preferably, the fixed base 100 and the connecting assembly 200 are an integral connection structure.

[0031] like Figures 1 to 3 As shown, preferentially, a first welding roughness 1201 is provided on the upper end face of the positioning side plate 120 adjacent to the column steel column 10, and a second welding roughness 101 is provided on the column steel column 10 corresponding to the first welding roughness 1201. The first welding roughness 1201 and the second welding roughness 101 are connected to each other. It can be understood that after the I-beam 20 is fixedly connected to the upper fastening plate 210, the two intermediate fastening plates 230 and the lower fastening plate 220 respectively by multiple high-strength bolts, the user can also weld and fix it through the exposed first welding roughness 1201 and the second welding roughness 101. This can further improve the structural connection stability between the positioning side plate 120 and the column steel column 10. Specifically, the first welding roughness 1201 and the second welding roughness 101 can be simply ground after cutting to have a high roughness value, thereby increasing the contact area between the welding material and the first welding roughness 1201 and the second welding roughness 101 respectively, and ensuring the welding quality. More specifically, the depth of the first weld roughness 1201 ranges from 3 mm to 5 mm; the depth of the second weld roughness 101 ranges from 1 mm to 3 mm.

Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
