Description

Technical Field

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

[0002] When assembling steel structures, if the connection holes between the columns and beams are not accurately aligned, the bolts may not be installed smoothly, or the bolts may be unevenly stressed after forced installation, reducing the effective cross-section of the bolt connection, thereby affecting the bearing capacity and stiffness of the connection node and increasing the risk of structural deformation. The existing technology generally uses laser centering instruments or template positioning methods to ensure the precise alignment of bolt connection holes, but this method requires additional equipment assistance and the assembly speed is slow.

[0022] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0023] A positioning connection structure of a beam 2 and a column 1, please refer to Figure 1-4 , comprising a column 1 and a beam 2;

[0024] Two connecting plates 3 arranged opposite to each other are fixed on the side of the column 1, and a reinforcing rib 7 is fixed between the connecting plate 3 and the outer side of the main body of the column 1, and a positioning plate 8 is fixed between the two connecting plates, and the positioning plate 8 is preferably fixedly connected to the column 1 to form an I-shaped torsion and shear resistant structure; the upper and lower sides of the end of the crossbeam 2 are provided with wing plates 4 extending outward, and a positioning groove 41 is opened through the middle of the wing plate 4, and a plurality of holes are opened on the surface of the connecting plate 3 and the wing plate 4;

[0025] During installation, the cross beam 2 is moved closer to the column 1 from the side, and the end of the cross beam 2 is inserted between the two connecting plates 3. At the same time, the positioning plate 8 is inserted into the positioning groove 41. The upper and lower wing plates 4 are respectively fitted with the upper and lower connecting plates 3. The holes on the surfaces of the connecting plates 3 and the wing plates 4 are coaxially opposite to each other. The cross beam 2 and the column 1 can be fixed together by passing the bolts through the holes and screwing on the nuts. After the positioning plate 8 is inserted into the positioning groove 41, the holes on the surfaces of the connecting plates 3 and the wing plates 4 are directly coaxially opposite to each other, which can play a role in rapid guiding and centering positioning, improve assembly efficiency, and the bolts and nuts need to be assembled in the horizontal direction.

[0026] As an implementation mode of the utility model, the connecting plate 3 is cross-shaped and has protruding parts extending from four sides of the column 1 respectively, and each protruding part can be connected to a beam 2. In this embodiment, the four sides of the column 1 can be connected to the beam 2 to form a cross-shaped connection structure, which can be widely used in the construction of various steel structures.

[0027] In addition, limiting blocks 5 are symmetrically arranged on both sides of the positioning plate 8, and the ends of the wing plates 4 have snap-in ends 42 extending outward. When the cross beam 2 is inserted between the connecting plates 3, the positioning plate 8 is inserted into the positioning groove 41 to play a guiding role until the snap-in end 42 is inserted into the gap between the limiting blocks 5 and the positioning blocks. The two limiting blocks 5 limit the lateral twisting between the cross beam 2 and the column 1 from both sides respectively. In addition, the two sides of the wing plates 4 are in contact with the surface of the limiting blocks 5, which also plays a role in reinforcing the firmness in the horizontal direction.

[0028] A baffle 6 is fixedly connected between the two wing plates 4 and the main body of the crossbeam 2. When assembled in place, the positioning plate 8 is fully inserted into the positioning groove 41, the end of the positioning plate 8 abuts against the surface of the baffle 6, and the two sides of the wing plate 4 abut against the surface of the limit block 5, further limiting the mobility of the crossbeam 2 and the column 1 in the horizontal direction and improving the stability of the connection between the two.

[0029] In this embodiment, the connecting plate 3 at least partially extends beyond the outer edge of the positioning plate 8. Figure 4 As shown, after assembly, the baffle 6, the positioning plate 8, etc. are all located within the range regulated by the connecting plate 3. After the bolts and nuts are positioned, the protruding edge of the connecting plate 3 improves the stability of the connection between the wing plate 4 and the connecting plate 3, counteracting the tension or shear force that the beam 2 may be subjected to in the longitudinal direction.

[0030] The above-described embodiments are merely descriptions of preferred implementations of the present invention, and are not intended to limit the concept and scope of the present invention. Without departing from the design concept of the present invention, various modifications and improvements made by ordinary personnel in the field to the technical solution of the present invention should fall within the protection scope of the present invention, and the technical contents of the present invention for protection have been fully recorded in the claims.
