[0002] Steel structure installation is an important process in building construction, which mainly involves the precise assembly of prefabricated steel components into designated positions according to design drawings. This process requires a high degree of technical precision and rigorous construction organization to ensure the stability and safety of the structure.

[0003] Existing steel structure main forms are being used more and more. Unlike traditional brick-concrete or reinforced concrete structures, the steel structure frame system is not constructed together with the floor slab, and it is not convenient to set up scaffolding and protective frames on the periphery. When installing and welding steel beams and columns, the periphery is mostly suspended. Workers need to move or operate on the steel beams without plates, which puts higher requirements on safety protection facilities.

However, this current fixing method has the disadvantage of low vertical stiffness. Under the action of occasional horizontal forces, there is a possibility of overturning, and the safety and reliability are low. For this reason, this application provides a steel structure installation protection device. Utility Model Content

The screw rod 8 and the connecting rod 6 are threadedly connected, and the connection between the first splint 2 and the column 3 is symmetrically fixed with a stiffening plate 22.

[0035] When in use, first take out the clamping plate 1 2 and the clamping plate 2 17 and clamp them on the flanges on both sides of the I-beam 1 respectively, and then tighten the bolts 21 to make the clamping plate 1 2 and the clamping plate 2 17 fastened to the I-beam 1, thereby improving the connection stability between the I-beam 1 and preventing the possibility of loosening during use, effectively improving the overall safety performance, and then manually twisting the stabilizing member to operate, and the stabilizing member is used to assist in improving the stability between the clamping plate 1 2 and the clamping plate 2 17 and the I-beam 1 again. When the clamping plate 1 2 and the clamping plate 2 17 are stable, the auxiliary rod 18 and the adjusting rod 19 can be driven to adjust the rotation angle. At this time, the position of the adjusting main ring 5 is moved to the appropriate position through the adjusting member according to the angle of the auxiliary rod 18 and the adjusting rod 19, and then the adjusting main ring 5 is fixed to the column 3 through the adjusting member. At this time According to the inclination angle of the adjusting rod 19, the angle of the adjusting sub-ring 7 is adjusted so that the adjusting rod 19 is inserted into the interior of the adjusting sub-ring 7. At this time, the clamping piece is operated to clamp and stabilize one end of the adjusting rod 19, so that a stable triangle system can be formed between the I-beam 1, the column 3, the sub-rod 18 and the adjusting rod 19. Through the multiple fixations and the principle of stability of the triangle, the steel structure installation protection forms a firm and reliable lifeline.

Finally, the device can be set at intervals along the flange of the I-beam 1, and the external steel wire rope can be passed through the threading hole 4 and fixed to the steel column. According to the safety specifications, the fixing measures are set up and the firmness between each position is checked one by one before it can be put into use.

[0036] Reference Figure 2 and Figure 3 The adjusting part includes a limiting column 10 which is slidably connected to the adjusting main ring 5. The end of the limiting column 10 away from the adjusting main ring 5 is fixedly connected to a connecting plate 11. One side of the connecting plate 11 is symmetrically fixedly connected to a spring 12. The end of the spring 12 away from the connecting plate 11 is fixedly connected to the outer wall of the adjusting main ring 5. The size of the limiting column 10 is consistent with the limiting hole 9.

[0037] When in use, first pull the connecting plate 11 to drive the limiting column 10 to be pulled out from the adjusting main ring 5, so that one end of the limiting column 10 is separated from the limiting hole 9. At this time, the position of the adjusting main ring 5 on the column 3 can be adjusted. When the position of the adjusting main ring 5 is moved to the appropriate position, the pulling on the connecting plate 11 can be released. At this time, according to the rebound of the spring 12, the connecting plate 11 can be driven to push the limiting column 10 into the limiting hole 9 at the corresponding position, so that the adjusting main ring 5 is fixed on the column 3.

[0038] Reference Figure 2 、 Figure 3 and Figure 4The clamping part includes two screw rods 13 symmetrically threaded through and connected to the adjusting sub-ring 7. One end of the two screw rods 13 is fixedly connected to a knob 14. The end of the screw rod 13 away from the knob 14 is fixedly connected to a clamping plate 15. The clamping plate 15 is located inside the adjusting sub-ring 7. One side of the clamping plate 15 is fixedly connected to an anti-slip pad 16, which is made of rubber.

[0039] When in use, first insert the adjusting rod 19 through the interior of the adjusting sub-ring 7, and then turn the two knobs 14 to drive the two screw rods 13 to rotate. As the two screw rods 13 continue to rotate, the inner walls of the two clamping plates 15 will fit tightly with the outer walls of the adjusting rod 19, so that one end of the adjusting rod 19 can be fixed inside the adjusting sub-ring 7 through the two clamping plates 15, so that a stable triangle system can be formed between the I-beam 1, the column 3, the sub-rod 18 and the adjusting rod 19. Through the multiple fixations and the principle of stability of the triangle, the steel structure installation protection forms a firm and reliable lifeline, and the two anti-slip pads 16 can greatly increase the friction between the clamping plates 15 and the adjusting rod 19, so that the adjusting rod 19 can be more stably fixed in the adjusting sub-ring 7, reducing the possibility of loosening.

[0040] Reference Figure 1 and Figure 2 A thread groove 20 is provided on one end of the adjusting rod 19 , and one end of the adjusting rod 19 is connected to the internal thread of the auxiliary rod 18 .

[0041] During use, since the auxiliary rod 18 and the adjusting rod 19 are threadedly connected, the adjusting rod 19 can be rotated according to the on-site conditions, so that the adjusting rod 19 gradually extends from the inside of the auxiliary rod 18, thereby realizing the extension and retraction of the adjusting rod 19, so that the adjusting rod 19 can be better inserted into the inside of the adjusting auxiliary ring 7.

[0042] Reference Figure 1 and Figure 2 The stabilizing member includes a fixing column 23 fixedly connected to the bottom of the plywood 1 2 and the plywood 2 17 , the bottom of the fixing column 23 is threadedly connected to a screw rod 3 24 , and the bottom of the screw rod 3 24 is fixedly connected to a contact plate 25 .

[0043] During use, after the initial fixation of splint 1 2 and splint 2 17 is completed, screw rod 3 24 can be manually rotated. Since screw rod 3 24 is threadedly connected to the fixing column 23, screw rod 3 24 will gradually extend from the inside of the fixing column 23 until the contact plate 25 is tightly fitted with the inner wall of the I-beam 1. Through the contact between screw rod 3 24 and the contact plate 25, splint 1 2 and splint 2 17 can be more stably fixed on the I-beam 1.

[0044] The implementation principle of the steel structure installation protection device of this embodiment is as follows: when in use, first take out the clamping plate 1 2 and the clamping plate 2 17 and clamp them on the flanges on both sides of the I-beam 1 respectively, and then tighten the bolts 21 to fasten the clamping plate 1 2 and the clamping plate 2 17 to the I-beam 1, so as to improve the connection stability between the clamping plate 1 2 and the clamping plate 2 17 and prevent the possibility of loosening during use, thereby effectively improving the overall safety performance. After the initial fixation of the clamping plate 1 2 and the clamping plate 2 17 is completed, the screw rod 3 24 can be manually rotated. Since the screw rod 3 24 is threadedly connected to the fixing column 23, the screw rod 3 24 will gradually extend from the inside of the fixing column 23 until the contact plate 25 is tightly fitted with the inner wall of the I-beam 1. Through the interference between the screw rod 3 24 and the contact plate 25, the When the clamping plate 11 is loosened and the clamping plate 12 is released, the connecting plate 11 is driven to push the limiting post 10 into the limiting hole 9 at the corresponding position, so that the main ring 5 is fixed on the column 3. At this time, according to the angle of the auxiliary rod 18 and the adjusting rod 19, the connecting plate 11 is pulled to drive the limiting post 10 to be pulled out from the adjusting main ring 5, so that one end of the limiting post 10 is separated from the limiting hole 9. At this time, the position of the adjusting main ring 5 on the column 3 can be adjusted. When the position of the adjusting main ring 5 is moved to the appropriate position, the pulling on the connecting plate 11 can be released. At this time, according to the rebound of the spring 12, the connecting plate 11 can be driven to push the limiting post 10 into the limiting hole 9 at the corresponding position, so that the adjusting main ring 5 is fixed on the column 3. The tilt angle is adjusted to adjust the angle of the adjusting sub-ring 7. Since the sub-rod 18 and the adjusting rod 19 are threadedly connected, the adjusting rod 19 can be rotated according to the on-site conditions, so that the adjusting rod 19 gradually extends from the inside of the sub-rod 18, thereby realizing the telescoping of the adjusting rod 19, so that the adjusting rod 19 can be better inserted into the inside of the adjusting sub-ring 7. At this time, the adjusting rod 19 is inserted into the inside of the adjusting sub-ring 7, and then the two knobs 14 are turned to drive the two screw rods 13 to rotate. As the two screw rods 13 continue to rotate, the inner walls of the two clamping plates 15 are tightly fitted with the outer walls of the adjusting rod 19, so that one end of the adjusting rod 19 is fixed to the inside of the adjusting sub-ring 7 through the two clamping plates 15, so that the I-beam 1 and the column 3 are , a stable triangle system can be formed between the auxiliary rod 18 and the adjusting rod 19. Through the multiple fixations therebetween and the principle of stability of the triangle, the steel structure installation protection forms a firm and reliable lifeline, and the two anti-slip pads 16 can greatly increase the friction between the clamping plate 15 and the adjusting rod 19, so that the adjusting rod 19 can be more stably fixed in the adjusting sub-ring 7, reducing the possibility of loosening. The auxiliary rod 18 and the adjusting rod 19 improve the stability of the vertical stiffness of the existing safety protection device. Finally, the device can be set at intervals along the flange of the I-beam 1, and the external steel wire rope can be passed through the threading hole 4 and fixed to the steel column. According to the requirements of safety regulations, set up the fixing measures and check the firmness between each position one by one.It can be put into use.
