Description

Technical Field

[0001] This utility model belongs to the field of steel structure construction technology, and in particular relates to an adjustable steel structure support. Background Technology

[0002] In current steel structure construction projects, high-altitude operations are a prominent feature. Traditional lifeline support systems have significant drawbacks before component hoisting: the conventional method involves welding standardized lifeline supports to the upper flange of the steel box girder. This can lead to serious consequences, such as lifeline failure due to welding defects. Subsequent dismantling and high-altitude cutting operations pose safety risks such as falls from heights and electric shocks, consuming significant time and manpower, and greatly impacting overall construction efficiency. This fails to meet the demands of modern engineering construction for quality, efficiency, and standardization. Therefore, there is an urgent need for a technical solution that can reduce welding and high-altitude cutting operations and enable reuse, thereby addressing the safety hazards and efficiency bottlenecks of existing technologies.

[0003] This utility model adopts a standardized lifeline bracket, which can be used directly on site. Installation does not require welding or hot work, which can greatly improve the installation efficiency of box-type steel beams.

[0004] It should be noted that the above content falls within the inventor's technical knowledge and does not necessarily constitute prior art. Utility Model Content

[0005] To address the aforementioned issues, the purpose of this invention is to provide an adjustable steel structure support that employs a mechanical fixing method of bolt fastening and screw adjustment. This eliminates the need for high-altitude hot work and cutting during subsequent dismantling, reducing manual intervention and improving overall construction efficiency and personnel safety.

[0006] To achieve the above objectives, this utility model proposes an adjustable steel structure support for fixing a steel box girder during hoisting. The steel structure support includes a fixing component, on which several support components for supporting the bottom of the steel box girder are installed.

[0007] The fastener includes an L-shaped plate and a vertical plate. The top plate of the L-shaped plate has symmetrically distributed guide holes, and the vertical plate has symmetrically distributed force transmission shafts fixed thereon. The force transmission shafts are slidably connected to the guide holes, and an adjusting component is connected between the L-shaped plate and the vertical plate.

[0008] Furthermore, the top plate of the L-shaped plate is provided with a threaded hole, and the adjusting component includes a first drive knob located on the vertical plate that rotates, and a first lead screw adapted to the threaded hole is fixed on the output shaft of the first drive knob.

[0009] Furthermore, the support members are evenly distributed on the vertical plates and vertical sides of the L-shaped plate.

[0010] Furthermore, the mounting position of the support member has a vertical sliding cavity inside, a rotating hole is provided below the sliding cavity, and a mounting hole is provided above the sliding cavity.

[0011] The support includes a second drive button that rotates within the mounting hole. A second lead screw is fixed on the shaft of the second drive button. A sliding strip is slidably provided in the sliding cavity. The upper end of the sliding strip has a threaded groove, and the lower end is rotatably provided with an L-shaped support rod for supporting the steel box girder.

[0012] Furthermore, the fastener is equipped with several fastening bolts for securing it to the steel box girder, and the fastening bolts are evenly distributed on the vertical plates and vertical sides of the L-shaped plate.

[0013] Furthermore, a vertical square tube is fixed above the fixing member.

[0014] Furthermore, several reinforcing plates are provided at the connection between the square tube and the fixing member.

[0030] An embodiment of this utility model proposes an adjustable steel structure support for fixing the steel box girder 1 during hoisting, such as... Figure 1 As shown, the steel structure support includes a fixing member 2, on which several support members 4 are installed for supporting the bottom of the steel box girder 1, and several fastening bolts 3 are installed on the fixing member 2 for fastening it to the steel box girder 1. A vertical square tube 5 is fixed above the fixing member 2, and several reinforcing plates 6 are provided at the connection between the square tube 5 and the fixing member 2. Several lifting buckles 7 for fixing the crane ropes are fixed on the square tube 5.

[0031] The fastener 2 includes an L-shaped plate 21 and a vertical plate 22. The top plate of the L-shaped plate 21 has threaded holes 212 and symmetrically distributed guide holes 211. Figure 2 As shown, symmetrically distributed force transmission shafts 221 are fixed on the vertical plate 22. The force transmission shafts 221 are slidably connected to the guide hole 211. An adjusting component 23 is connected between the L-shaped plate 21 and the vertical plate 22.

[0032] The adjusting component 23 includes a first drive knob 231 that rotates on the vertical plate 22, and a first lead screw 232 that is adapted to the threaded hole 212 is fixed on the output shaft of the first drive knob 231.

[0033] The fastening bolts 3 are evenly distributed on the vertical plate and vertical plate 22 of the L-shaped plate 21, and are used to fix the two sides of the steel box girder 1.

[0034] Support members 4 are evenly distributed on the vertical plates and vertical plates 22 of the L-shaped plate 21. Vertical sliding cavities 222 are provided inside the installation positions of the support members 4, such as... Figure 3 As shown, a rotating hole 223 is provided below the sliding cavity 222, and a mounting hole 224 is provided above it.

[0035] The support member 4 includes a second drive button 41 that rotates within the mounting hole 224. A second lead screw 42 is fixed on the shaft of the second drive button 41. A sliding strip 43 is slidably provided in the sliding cavity 222. A threaded groove 44 is provided at the upper end of the sliding strip 43, and an L-shaped support rod 45 for supporting the steel box girder 1 is rotatably provided at the lower end.

[0036] Working principle:

[0037] Fixed adjustment (steel box girder 1 clamped and fixed).

[0038] Function of fastening bolt 3:

[0039] The fastening bolts 3, which are evenly distributed on the vertical plate 21 and the vertical plate 22 of the L-shaped plate 21, clamp the steel box girder 1 from both sides by tightening, ensuring a stable connection between the steel structure support and the steel box girder 1 and preventing displacement during hoisting.

[0040] Width adaptive adjustment:

[0041] The force transmission shaft 221 is engaged with the guide hole 211: the force transmission shaft 221 of the vertical plate 22 can slide within the guide hole 211 of the L-shaped plate 21, allowing the vertical plate 22 to move laterally.

[0042] First lead screw 232 drive adjustment: Rotate the first drive knob 231 to drive the first lead screw 232 into the threaded hole 212 of the L-shaped plate top plate, push the vertical plate 22 to move along the force transmission axis, thereby adapting to steel box beams 1 of different widths and enhancing the clamping force.

[0043] Height adjustment (overall lifting of steel structure support):

[0044] Square tube 5 and hanging buckle 7 are linked:

[0045] The square tube 5, fixed above the fixing component 2, is connected to the crane rope via the lifting buckle 7. During hoisting, the lifting and lowering of the steel structure support and the steel box girder 1 are controlled by the crane.

[0046] Strengthen structural protection:

[0047] The reinforcing plate 6 at the connection between the square tube 5 and the fixing component 2 distributes the force to prevent deformation or breakage due to excessive load during hoisting.

[0048] Support adjustment (bottom support of steel box girder 1):

[0049] Support height fine-tuning:

[0050] Screw-driven lifting: Rotate the second drive knob 41 to drive the second screw 42 to rotate, which engages with the threaded groove 44 at the upper end of the sliding bar 43, pushing the sliding bar 43 to move up and down in the sliding cavity 222.

[0051] L-shaped support rod 45 action: The L-shaped support rod 45 at the lower end of the sliding bar 43 rises and falls with the sliding bar, precisely adjusting the support height to ensure that the bottom of the steel box girder 1 is subjected to uniform force and avoid local stress concentration.

[0052] Dynamic adaptability:

[0053] The support components 4 are evenly distributed, and the height of each support point can be adjusted individually according to the shape of the bottom of the steel box girder or the load distribution to improve the stability of the fixation.

[0054] Collaborative workflow:

[0055] Installation phase: Adjust the first drive button 231 to move the vertical plate 22, and after matching the width of the steel box girder 1, tighten the fastening bolts 3.

[0056] Supporting stage: Adjust the second drive knob 41 one by one to make all L-shaped support rods 45 fit tightly against the bottom of the steel box girder and bear the load.

[0057] During the hoisting phase: The crane lifts the square tube 5 through the lifting buckle 7, which drives the steel structure support and the steel box girder 1 to move synchronously, maintaining stable clamping force and support force throughout the process.
