Description

Technical Field

[0001] The utility model relates to the technical field of steel structures, in particular to a connection structure of an H-shaped steel structure. Background Art

[0002] Steel structure is one of the types of building structures. According to the different installation positions, it can be divided into horizontal steel beams, vertical steel columns and inclined steel trusses. In actual use, different steel structures can be fixed by welding, bolting or riveting. The H-shaped steel structure is a component with an "H"-shaped cross-section. When it is connected to a steel column as a steel beam, the H-shaped steel structure cannot be directly connected to the steel column by bolts or rivets. Therefore, there are usually two ways to connect the H-shaped steel structure to the steel column. One way is to directly connect them by welding. In this way, the H-shaped steel structure and the steel column are not easy to disassemble, which brings inconvenience to subsequent reuse; the other form is to first weld a connecting plate at the end of the H-shaped steel structure, and the extension direction of the connecting plate and the H-shaped steel structure are perpendicular to each other, and then fix the connecting plate on the steel column by bolting or riveting. Although this method is convenient for disassembling the H-shaped steel structure, the connecting plate welded at its end changes the structure of the H-shaped steel structure itself, which also brings certain troubles to subsequent reuse. In addition, welding the connecting plate will increase the production cost, which is not conducive to the company's control of production costs. Utility Model Content

DETAILED DESCRIPTION

[0025] Now the utility model is described in detail with reference to the accompanying drawings. This figure is a simplified schematic diagram, which only illustrates the basic structure of the utility model in a schematic manner, so it only shows the components related to the utility model.

[0026] See also Figure 1-Figure 7 The utility model provides a connection structure of an H-shaped steel structure, including a steel column 1 and an H-shaped steel structure 2 connected to each other, wherein the steel column 1 is vertically arranged and the H-shaped steel structure 2 is horizontally arranged, wherein the longitudinal section of the H-shaped steel structure 2 is an "H"-shaped structure, and the H-shaped steel structure 2 includes two horizontal steel plates 21 arranged opposite to each other and a vertical steel plate 22 connected between the two horizontal steel plates 21. A connecting plate 4 is fixedly installed at the end of the H-shaped steel structure 2 by a first bolt 3, and a fixing sleeve 5 is slidably provided on the outside of the H-shaped steel structure 2, and the fixing sleeve 5 is fixedly connected to the steel column 1 by a second bolt 6, and a receiving groove 51 is provided at the end of the fixing sleeve 5, and the connecting plate 4 is partially squeezed and fixed in the space enclosed by the steel column 1 and the receiving groove 51.

[0027] In the connection structure of the H-shaped steel structure of the utility model, when the steel column 1 and the H-shaped steel structure 2 are connected, the fixing sleeve 5 is first sleeved on the outside of the H-shaped steel structure 2, and then the connecting plate 4 is fixedly installed on the end of the H-shaped steel structure 2 by the first bolt 3, and then the fixing sleeve 5 is slid to the end of the H-shaped steel structure 2 with the connecting plate 4, and the fixing sleeve 5 is fixedly installed on the side wall of the steel column 1 by the second bolt 6. After the fixing is completed, the connecting plate 4 is partially squeezed and fixed in the space surrounded by the steel column 1 and the receiving groove 51. Through the above connection method, the user only needs the first bolt 3 and the second bolt 6 to fix the steel column 1 and the H-shaped steel structure 2. No welding operation is required, which saves costs. At the same time, it is also easy to disassemble, ensuring that the H-shaped steel structure 2 can be reused later. The connecting plate 4 fixedly installed on the H-shaped steel structure 2 is fixedly squeezed in the receiving groove 51, thereby realizing the fixed connection relationship between the connecting plate 4 and the steel column 1. The user only needs to use the second bolt 6 to realize the fixing effect of the connecting plate 4. The structural design is reasonable and easy to operate. At the same time, the fixing sleeve 5 is fitted onto the outside of one end of the H-shaped steel structure 2 , thereby enhancing the structural strength of the end of the H-shaped steel structure 2 and ensuring the connection stability between the H-shaped steel structure 2 and the steel column 1 .

[0028] In this embodiment, the connecting plate 4 is in an L-shaped structure, and includes a fixing portion 41 and an extruding portion 42 connected to each other, and both the fixing portion 41 and the extruding portion 42 are in a rectangular flat plate structure, and the fixing portion 41 and the extruding portion 42 are perpendicular to each other. Among them, the fixing portion 41 fits the vertical steel plate 22, and the fixing portion 41 is fixedly connected to the vertical steel plate 22 by the first bolt 3, and the extruding portion 42 is extruded and fixed in the space enclosed by the steel column 1 and the receiving groove 51.

[0029] Furthermore, the height of the fixing portion 41 is equal to the vertical distance between the two horizontal steel plates 21, so that the upper and lower end surfaces of the fixing portion 41 are respectively fitted with the two horizontal steel plates 21. In this way, the fixing portion 41 can act as a reinforcing rib to enhance the structural strength of the end of the H-shaped steel structure 2.

[0030] In addition, two connecting plates 4 are provided on both sides of any end of the H-shaped steel structure 2, and the two connecting plates 4 are symmetrically arranged. When installing the connecting plate 4, after one end of the first bolt 3 passes through the connecting plate 4 and the vertical steel plate 22 in sequence, a nut 31 is installed at the end of the first bolt 3, thereby playing a tightening role and preventing the first bolt 3 from detaching. In this embodiment, there are three first bolts 3, and the three first bolts 3 are arranged in sequence in the longitudinal direction, which enhances the connection stability between the fixing portion 41 and the vertical steel plate 22.

[0031] Furthermore, the maximum distance H between the two extrusion portions 42 on the two connecting plates 4 on the same side of the H-shaped steel structure 2 is slightly smaller than the width L of the receiving groove 51 (see Figure 7), the purpose of doing so is to ensure that when the fixing sleeve 5 moves into place, the extrusion portion 42 can be placed in the accommodating groove 51 to avoid interference between the extrusion portion 42 and the fixing sleeve 5.

[0032] Please refer again Figure 3 , Figure 7 As a preferred embodiment, an escape groove 52 is provided on the bottom wall of the receiving groove 51, and the fixing portion 41 and the first bolt 3 are located in the escape groove 52. By providing the escape groove 52, when the fixing sleeve 5 is moved to the end of the H-shaped steel structure 2, the escape groove 52 can accommodate the fixing portion 41 and the first bolt 3, so as to facilitate squeezing the extrusion portion 42 into the receiving groove 51.

[0033] Also, please refer again to Figure 4 A through slot 53 is provided at the center of the fixing sleeve 5. The through slot 53 is connected to the avoidance slot 52. The shape of the through slot 53 is the same as the cross section of the H-shaped steel structure 2. The fixing sleeve 5 can be slidably mounted on the outside of the H-shaped steel structure 2 through the through slot 53. By providing the through slot 53, the contact area between the fixing sleeve 5 and the H-shaped steel structure 2 is increased, thereby enhancing the stability of the relative position between the fixing sleeve 5 and the H-shaped steel structure 2, so that the fixing sleeve 5 can play a better limiting role on the H-shaped steel structure 2.

[0034] In this embodiment, the fixing sleeve 5 is a rectangular block structure, and a fixing edge 54 is protruded from the outer edge of the fixing sleeve 5 along the length direction perpendicular to the H-shaped steel structure 2, and the fixing edge 54 is fixedly connected to the steel column 1 through the second bolt 6. In addition, there are multiple second bolts 6, and multiple second bolts 6 are arranged along the fixing edge 54, so as to fix the fixing sleeve 5 at multiple points around the fixing sleeve 5, thereby improving the connection stability between the fixing sleeve 5 and the steel column 1.

[0035] When disassembling the connection structure of the H-shaped steel structure of the utility model, the second bolt 6 is first removed to separate the fixing edge 54 from the steel column 1, and then the fixing sleeve 5 is slid along the H-shaped steel structure 2 to expose the connecting plate 4, and then the first bolt 3 is removed, the connecting plate 4 is removed, and finally the fixing sleeve 5 is slid out from one end of the H-shaped steel structure 2. At this point, the disassembly process is completed. Compared with the prior art, the operation is simple and convenient, and the original structure of the H-shaped steel structure 2 can be kept unchanged, which is conducive to subsequent reuse.

[0036] Based on the above ideal embodiments of the utility model, the relevant staff can make various changes and modifications without departing from the scope of the utility model through the above description. The technical scope of this utility model is not limited to the contents of the specification, and its technical scope must be determined according to the scope of the claims.
