Technical Field

[0001] The utility model relates to the field of building structures, in particular to an adjustable supporting device for building steel structures. Background Art

[0002] A steel structure is a major type of building structure made of steel. It primarily consists of components such as beams, columns, and trusses made from sections and plates. These components are typically connected using welds, bolts, or rivets.

[0003] For example, the publication (announcement) number: CN218815432U discloses a steel structure support device for a construction project, comprising an upper beam and a lower beam, with a damping support structure installed between the upper beam and the lower beam.

[0004] In the above scheme, the upper and lower beams are adjusted by a damping support structure. However, due to the large lengths of the upper and lower beams, the single damping support structure has poor support stability for the upper and lower beams. Therefore, an adjustable support device for a building steel structure is proposed. Utility Model Content

[0005] In view of the above problems existing in the existing building steel structure supporting device, the present utility model is proposed.

[0006] Therefore, the purpose of the present invention is to provide an adjustable support device for a building steel structure, which solves the problems raised in the background art.

[0007] In order to achieve the above purpose, the present invention provides the following technical solutions:

[0009] Preferably, the lower cross beam is detachably provided with a slide rail, and two sliders are rotatably provided inside the slide rail, a second U-shaped block is fixed on the top of the slider, and the end of the support rod is rotatably connected to the second U-shaped block.

[0010] Preferably, first screw rods are fixedly provided on both sides of the sliding block, a strip-shaped opening for the first screw rod to pass through is opened on the side wall of the sliding rail, and a first nut is provided on the rod wall of the first screw rod.

[0011] Preferably, two second screws are symmetrically fixed on the side walls of the slide rail, a mounting hole for the second screw to pass through is opened on the side wall of the lower cross beam, and a second nut is provided on the rod wall of the second screw, and the setting between the upper cross beam and the slide rail is the same as the setting between the lower cross beam and the slide rail.

[0012] Furthermore, a gripping bracelet is fixedly provided on the rod wall of the bidirectional screw.

[0013] Preferably, the support rod is made of alloy steel rod.

[0014] In the above technical solution, the technical effects and advantages provided by the utility model are:

[0015] 1. The utility model, through the support rod, bidirectional screw, screw sleeve and first U-shaped seat arranged between the lower crossbeam and the upper crossbeam, the two support rods are in an X-shaped structure, which can firmly support the lower crossbeam and the upper crossbeam, thereby improving the strength of the building steel structure. When the lower crossbeam and the upper crossbeam need to be adjusted, the bidirectional screw is turned by hand, and the bidirectional screw drives the two screw sleeves to move closer or farther away from each other during rotation, thereby enabling the two support rods to rotate and adjust the distance between the lower crossbeam and the upper crossbeam.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0025] The utility model provides Figure 1 The adjustable support device of a building steel structure shown in the figure includes a lower crossbeam 1 and an upper crossbeam 2. Two cross-arranged support rods 3 are provided between the lower crossbeam 1 and the upper crossbeam 2. The middle parts of the two support rods 3 are rotatably connected by a rotating shaft 4. The support rods 3 are made of alloy steel rods. The structural strength of the alloy steel material is high and can firmly support the lower crossbeam 1 and the upper crossbeam 2. The two ends of the two support rods 3 are respectively slidably connected to the lower crossbeam 1 and the upper crossbeam 2; a bidirectional screw 5 is provided laterally on the lower side between the two support rods 3. 5 is fixed with a holding bracelet 15 on the rod wall, and both ends of the two bidirectional screws 5 are threaded with screw sleeves 6. The rod walls of the two support rods 3 are fixed with a first U-shaped seat 7, and the first U-shaped seat 7 is rotatably connected to the screw sleeve 6. When it is necessary to adjust the distance between the lower crossbeam 1 and the upper crossbeam 2, the hand holds the holding bracelet 15 tightly and rotates the bidirectional screw 5. When the bidirectional screw 5 rotates, the two screw sleeves 6 are driven to move relatively closer or farther away, thereby enabling the two support rods 3 to rotate and adjust the distance between the lower crossbeam 1 and the upper crossbeam 2.

[0026] like Figure 1-2 As shown, the lower crossbeam 1 is detachably provided with a slide rail 8, and two sliders 9 are rotatably provided inside the slide rail 8. A second U-shaped block 10 is fixedly provided on the top of the slider 9. The end of the support rod 3 is rotatably connected to the second U-shaped block 10. A first screw 11 is fixedly provided on both sides of the slider 9. The side wall of the slide rail 8 is provided with a strip-shaped opening for the first screw 11 to pass through, and the rod wall of the first screw 11 is provided with a first nut 12. During the rotation of the support rod 3, the slider 9 moves inside the slide rail 8. After the position between the lower crossbeam 1 and the upper crossbeam 2 is adjusted to be appropriate, the first nut 12 is tightened with a wrench to fix the position between the first screw 11 and the slide rail 8, thereby increasing the support stability of the support rod 3 on the lower crossbeam 1 and the upper crossbeam 2.

[0027] like Figure 1 and 3As shown, two second screws 13 are symmetrically fixed on the side walls of the slide rail 8, a mounting hole for the second screw 13 to pass through is opened on the side wall of the lower cross beam 1, and a second nut 14 is provided on the rod wall of the second screw 13. The setting between the upper cross beam 2 and the slide rail 8 is the same as the setting between the lower cross beam 1 and the slide rail 8. When it is necessary to disassemble the slide rail 8 and the lower cross beam 1 and the upper cross beam 2, the second nut 14 is loosened with a wrench to remove the second screw 13 from the mounting holes on the lower cross beam 1 and the upper cross beam 2.

[0028] When in use: first fix the slide rail 8 between the upper beam 2 and the lower beam 1, then hold the wristband 15 tightly with your hand and rotate the bidirectional screw 5. The bidirectional screw 5 drives the two screw sleeves 6 to move closer or farther away from each other during rotation, thereby enabling the two support rods 3 to rotate and adjust the distance between the lower beam 1 and the upper beam 2. At the same time, since the two support rods 3 are in an X-shaped structure, they can firmly support the lower beam 1 and the upper beam 2, thereby improving the strength of the building steel structure.

[0029] The above description is merely illustrative of certain exemplary embodiments of the present invention. It goes without saying that those skilled in the art will be able to modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and description are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
