Description

Technical Field

[0001] The utility model relates to the technical field of assembled steel components, and specifically relates to an anti-deformation structure for assembled steel components. Background Technique

[0002] Steel components refer to steel structure composite components that can bear and transfer loads, which are connected by steel plates, angle steels, channel steels, I-beams, welded or hot-rolled H-beams through cold bending or welding with connectors. In order to prevent the steel components from yielding or breaking under load, a support structure is also added to the steel components to further improve the load-bearing capacity of the steel components.

[0003] For example, the published document with the application number 202120194926.4 discloses a green integrated assembled steel component. The utility model is provided with strengthening columns on the web. On the basis of welding and fixing the web and the flange, through the strengthening columns and through holes, the web and the flange are additionally clamped and fixed, so that the double connection of the two greatly improves the strength of the two, making it not easy for the web and the flange to deform. However, for this assembled steel component, when supporting the flange and the web, grooves are opened on the surfaces of the flange and the web. The grooves not only weaken the central thickness of the steel component, causing changes in the overall load-bearing performance of the steel component, but also under excessive pressure, the stressed points of mutual extrusion will be dispersed to the reinforcing strips that are spliced together up and down. The gap part in contact with the reinforcing strips becomes a new bending point, resulting in the possibility that the upper flange or web may still bend and deform through this point, and only the stressed point of the bending deformation is transferred from the welding place to the joint of the reinforcing strips. Therefore, although this structure can strengthen the strength of the welded part of the steel component, it is still difficult to ensure the strength of the splicing position of the reinforcing strip part.

[0004] Therefore, in view of this, in view of the deficiencies of the existing structure, research and improvement are carried out, and an anti-deformation structure for assembled steel components is proposed. Content of the Utility Model

[0005] The purpose of the utility model is to provide an anti-deformation structure for assembled steel components to solve the problems put forward in the above background technique.

[0006] To achieve the above purpose, the utility model provides the following technical solution: an anti-deformation structure for assembled steel components, including a steel structure column, wing plates are welded and fixed at both the upper and lower ends of the steel structure column, and support mechanisms are arranged on the left and right sides of the connection parts between the wing plates and the upper and lower ends of the steel structure column, and an adjustment mechanism is arranged outside the support mechanism.

[0007] Preferably, the support mechanism includes the same support plate fixedly arranged on the left and right sides of the upper and lower ends of the steel structure column and on the same side of the surface of the wing plate, and a cross plate is fixedly installed on the surface of the support plate close to the steel structure column.

[0008] Preferably, the support mechanism further includes a damping spring rod fixedly installed on the surface of the cross plate near one side of the wing plate, and the damping spring rod is composed of a damper and a spring.

[0009] Preferably, the support mechanism further includes a movable plate fixedly installed at the end of the damping spring rod, and the movable plate is attached to the surface of the wing plate.

[0010] Preferably, the adjustment mechanism includes fixing plates fixedly installed on the outer sides of the upper and lower same-side support plates, and a sleeve plate is sleeved outside the fixing plates.

[0011] Preferably, the adjustment mechanism further includes a bidirectional lead screw threadedly connected to the inner surfaces of the upper and lower two support plates. A driven bevel gear is fixedly installed in the middle of the surface of the bidirectional lead screw. A driving bevel gear is meshed on one side of the surface of the driven bevel gear. The right end of the driving bevel gear is fixedly provided with a hand wheel through a connecting rod penetrating through the sleeve plate.

[0012] Preferably, positioning holes are uniformly distributed around the penetrating part of the connecting rod of the driving bevel gear on the outer middle surface of the sleeve plate. A pin is inserted into the positioning holes, and the end of the pin away from the positioning holes slidably penetrates through the hand wheel.

[0013] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0014] 1. Through the settings of the support mechanism, support plates, cross plate, damping spring rod and movable plate of the present utility model, the support plates are on the two right-angled sides of the welding joint of the steel structure column and the wing plate, further fixedly connecting the steel structure column and the wing plate. When the steel structure column and the wing plate are stressed, the force received by the welding part is assisted by the support plates to transfer the stress to the integral part of the entire column or plate body, effectively preventing the welding part from deforming and breaking due to excessive stress, thereby greatly improving the morphological stability of the steel structure parts. The seismic force transmitted to the whole steel structure will be transmitted through the cross plate to the movable plate, causing the movable plate to squeeze the damping spring rod to contract, buffering the seismic force and preventing the welding part from being directly stressed and causing impact fracture, further improving the morphological stability and use stability of the steel structure parts;

[0015] 2. Through the settings of the adjustment mechanism, fixing plates, sleeve plate, bidirectional lead screw, driven bevel gear, driving bevel gear and hand wheel of the present utility model, rotating the hand wheel can drive the driving bevel gear to rotate, meshing with the driven bevel gear to rotate synchronously, driving the bidirectional lead screw to rotate. Under the limitation of the sleeve plate on the fixing plate inside, the bidirectional lead screw pushes the fixing plate to extend, thereby adjusting the upper and lower two support mechanisms on the same side to extend and adjusting the height distance between the upper and lower ends, enabling the support mechanism to adapt to steel structure columns of different heights for support, greatly improving the flexibility and adaptability of the entire support mechanism in use;

[0016] 3. By providing positioning holes and pins, the utility model enables the pin to penetrate through the handwheel and insert into the positioning hole at the nearest corresponding point. The positioning hole limits the pin, and the pin limits the handwheel, thereby fixing the extension distance of the entire adjustment mechanism, preventing the handwheel from rotating again and causing distance changes, and enabling the adjustment mechanism to adjust the distance of the support mechanism more precisely and stably.

DETAILED DESCRIPTION OF THE EMBODIMENTS

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments in the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0023] As Figure 1 - Figure 2 shown, an anti-deformation structure for prefabricated steel components includes a steel structure column 1. Wing plates 2 are welded and fixed to both the upper and lower ends of the steel structure column 1. Support mechanisms 3 are provided on both the left and right sides of the connection parts between the wing plates 2 and the upper and lower ends of the steel structure column 1, and an adjustment mechanism 4 is provided outside the support mechanism 3.

[0024] Furthermore, the support mechanism 3 includes a same support plate 301 fixedly provided on both the left and right sides of the upper and lower ends of the steel structure column 1 and on the same side of the surface of the wing plate 2, and a cross plate 302 is fixedly installed on the surface of the support plate 301 near the steel structure column 1.

[0025] By adopting the above technical solution, the support plate 301 further fixedly connects the steel structure column 1 and the wing plate 2 on both sides of the right angle at the welding joint of the steel structure column 1 and the wing plate 2. When the steel structure column 1 and the wing plate 2 are stressed, the force received by the welding part is assisted by the support plate 301 to transfer the stress to the integral part of the entire column or plate, effectively preventing the welding part from deforming and breaking due to excessive stress.

[0026] Furthermore, the support mechanism 3 further includes a damping spring rod 303 fixedly installed on the surface of the transverse plate 302 near the wing plate 2 side. The damping spring rod 303 is composed of a damper and a spring.

[0027] By adopting the above technical solution, the damping spring rod 303 can buffer the shock force by using the damper to contract, and can be extended and reset by using the spring.

[0028] Furthermore, the support mechanism 3 further includes a movable plate 304 fixedly installed at the end of the damping spring rod 303, and the movable plate 304 is attached to the surface of the wing plate 2.

[0029] By adopting the above technical solution, the movable plate 304 attached to the wing plate 2 can effectively absorb the transmitted shock force, thereby squeezing the damping spring rod 303.

[0030] As Figure 2 - Figure 4 shown, the adjusting mechanism 4 includes fixing plates 401 fixedly installed on the outer sides of the upper and lower same-side surfaces of the support plate 301, and a sleeve plate 402 is sleeved outside the fixing plate 401.

[0031] By adopting the above technical solution, the sleeve plate 402 limits the periphery of the surface of the fixing plate 401.

[0032] Furthermore, the adjusting mechanism 4 further includes a bidirectional lead screw 403 threadedly connected to the inner surfaces of the upper and lower two support plates 301. A driven bevel gear 404 is fixedly installed in the middle of the surface of the bidirectional lead screw 403. A driving bevel gear 405 is meshed on one side of the surface of the driven bevel gear 404. The right end of the driving bevel gear 405 is fixedly provided with a hand wheel 406 through a connecting rod penetrating the sleeve plate 402.

[0033] By adopting the above technical solution, manually driving the driving bevel gear 405 by using the hand wheel 406 to drive the driven bevel gear 404 to rotate, so that the bidirectional lead screw 403 rotates, the fixing plate 401 can extend outward to the upper and lower ends, and the support mechanism 3 can be pushed to adjust the distance.

[0034] Furthermore, positioning holes 5 are uniformly distributed around the penetrating part of the connecting rod of the driving bevel gear 405 on the outer side of the surface of the sleeve plate 402. A pin 6 is inserted into the positioning hole 5, and one end of the pin 6 far from the positioning hole 5 slidably penetrates the hand wheel 406.

[0035] By adopting the above technical solution, the adjustment position of the adjusting mechanism 4 can be fixed by inserting the bolt 6 through the handwheel 406 into the positioning hole 5, preventing the handwheel 406 from rotating again.

[0036] Working principle: When using this anti-deformation structure for assembled steel components, first, rotating the handwheel 406 can drive the driving bevel gear 405 to rotate, meshing with the driven bevel gear 404 to rotate synchronously, driving the bidirectional lead screw 403 to rotate. Under the limitation of the fixed plate 401 inside the sleeve plate 402, the bidirectional lead screw 403 pushes the fixed plate 401 to extend, thereby adjusting the two support mechanisms 3 at the upper and lower ends on the same side to extend, adjusting the height distance between the upper and lower ends, so that the support mechanism 3 can support the steel structure column 1 of different heights. Then, use the bolt 6 to pass through the handwheel 406 and insert it into the positioning hole 5 at the nearest corresponding point. The positioning hole 5 limits the bolt 6, and the bolt 6 limits the handwheel 406, so as to fix the extension distance of the entire adjusting mechanism 4, avoiding the handwheel 406 from rotating again. After fixing, the support plate 301 can be installed with the steel structure column 1 and the wing plate 2. The support plate 301 is on both right-angled sides of the welded joint between the steel structure column 1 and the wing plate 2, further fixedly connecting the steel structure column 1 and the wing plate 2. When the steel structure column 1 and the wing plate 2 are stressed, the force received by the welded part is assisted by the support plate 301 to transfer the stress to the integral part of the entire column or plate body, effectively preventing the welded part from deforming and breaking due to excessive stress. The seismic force transmitted to the overall steel structure will be transmitted to the movable plate 304 through the cross plate 302, causing the movable plate 304 to squeeze the damping spring rod 303 to contract, buffering the seismic force and preventing the welded part from being directly stressed and causing impact fracture. This is the working principle of this anti-deformation structure for assembled steel components.
