[0001] The present application relates to the technical field of steel structures, and in particular to a high-stability connection structure applied to steel materials. Background Art
[0002] Steel is characterized by high strength, light weight, good overall rigidity, and strong resistance to deformation, making it particularly suitable for constructing large-span, ultra-high, and ultra-heavy buildings. Its homogeneity and isotropy make it an ideal elastic body, which best conforms to the basic assumptions of general engineering mechanics. Its plasticity and toughness allow for significant deformation and excellent ability to withstand dynamic loads. Consequently, steel is commonly used in steel-structured buildings, and due to their short construction periods, it is gradually gaining popularity in the construction industry.
[0003] In the existing technology, during the construction process of steel structures, steel materials need to be connected into one piece by welding or screwing. During the connection process, at least two people are required to work synchronously, one of whom needs to align the ends of the two steel materials while the other performs the welding or screwing operation to complete the stable connection of the steel materials. Utility Model Content

DETAILED DESCRIPTION
[0020] The following will describe in detail the embodiments of the technical solution of the present application in conjunction with the accompanying drawings. The following embodiments are only used to more clearly illustrate the technical solution of the present application and are therefore only used as examples and cannot be used to limit the scope of protection of the present application.

[0021] Specifically, please refer to Figures 1 to 3 , Figure 1 This is a schematic diagram of the overall cross-sectional structure of a high-stability connection structure for steel provided in an embodiment of the present application. Figure 2 This is a side view of the positioning tube provided in an embodiment of the present application. Figure 3FIG. 0 is a partial structural schematic diagram of the sleeve component provided by the embodiment of the present application. The high-stability connection structure 100 for steel includes two positioning cylinders 110 with opposite ends. The two positioning cylinders 110 are respectively used to connect with two steel pieces to be connected. During the connection process, the steel pieces to be welded need to be inserted into the two positioning cylinders 110 respectively (the aperture of the positioning cylinder 110 is slightly larger than that of the steel piece to be welded). Therefore, according to different actual situations, the cross-sectional shape of the positioning cylinder 110 can be set in different forms to make the steel piece to be welded and the positioning cylinder 110 fit better. A plurality of support rods 120 are distributed in an annular array on the outer periphery of the positioning cylinder 110. The support rods 120 have a certain diameter to ensure that they can provide sufficient rigid support for the positioning cylinder 110, so that the central axes of the two positioning cylinders 110 are always on the same straight line, and then ensure that the two steel pieces to be welded can be effectively aligned subsequently. A plurality of sleeve components 121 are slidably arranged on the support rods 120. The outer side wall of the sleeve component 121 is connected to the outer side wall of the positioning cylinder 110 through a connecting rod 122. The sleeve component 121 is fixedly connected to the outer side wall of the positioning cylinder 110 through the connecting rod 122. Furthermore, the positioning cylinder 110 and the sleeve component 121 can be regarded as an integral body and can slide along the axial direction of the support rod 120. One end of the two positioning cylinders 110 close to each other is a limiting end 111, and one end of the two positioning cylinders 110 far from each other is an insertion end 112. A plurality of slots 113 are opened at the port of the limiting end 111 of the positioning cylinder 110. A sector-shaped movable member 140 is hinged in the slot 113. The sector-shaped movable member 140 is used to clamp the steel piece to be welded in the positioning cylinder 110 under the push of the positioning ring 150 to ensure that the port part of the steel piece to be welded does not shake during the welding process and has a certain stability. One side of the back of the sector-shaped movable member 140 is a smooth surface, and one side of the inside of the sector-shaped movable member 140 is an elastic surface. The smooth surface facilitates the positioning ring 150 to slide on its outer periphery, and the elastic surface enables it to fit more stably with the outer side surface of the steel piece to be welded. A positioning ring 150 is sleeved on the outer side wall of the limiting end 111 of the positioning cylinder 110. The positioning ring 150 is provided with internal threads, and the outer side wall of the positioning cylinder 110 is provided with external threads. The positioning ring 150 is screwed with the positioning cylinder 110. During the rotation of the positioning ring 150, through the cooperation of the internal threads and the external threads, the positioning ring 150 will approach the sector-shaped movable member 140. Further, the inner wall of the positioning ring 150 will squeeze the smooth outer surface of the sector-shaped movable member 140. After being pressed, the sector-shaped movable member 140 rotates inwards until the inner side wall of the sector-shaped movable member 140 squeezes and covers the outer periphery of the steel piece to be welded. At this time, a plurality of sector-shaped movable members 140 respectively squeeze the outer periphery of the steel piece to be welded from all directions, and the position of the steel piece to be welded will be fixed. Subsequently, by pushing the form of the positioning cylinder 110, the sleeve components 121 slide on the support rods 120 respectively, and the two steel pieces to be welded are butted together. At this time, welding operations can be carried out.
[0022] As can be seen from the above, in the embodiment of the present application, the operator can insert the two steels to be welded or screwed into the positioning cylinder 110 respectively during the operation, and then rotate the positioning cylinder 110 so that the positioning cylinder 110 squeezes the fan-shaped movable part 140. The fan-shaped movable part 140 flips around its hinge point and squeezes on the steel to be welded. After the two steels to be welded are fixed respectively, the positioning cylinder 110 can be pushed so that the sleeve part 121 slides respectively on the support rod 120, and then the two steels to be welded are connected together. At this time, the operator can start to complete the welding or screwing operation of the steels, and the entire operation can be completed by only one person without the need for additional personnel assistance. On the other hand, the present application positions and connects the positioning tube 110 by setting up multiple support rods 120. There is a certain gap between the multiple support rods 120, and the operator can extend the end of the steel to be welded beyond one end of the positioning tube 110 during the process of fixing the steel to be welded. At this time, the operator can pass through the gap between the multiple support rods 120 and extend the welding equipment into the butt-jointed ends of the two steels to be welded to perform welding and other operations without being affected by the equipment.
[0023] In some embodiments, there are four support rods 120, each of which is provided with four sleeve components 121. The four sleeve components 121 are grouped in pairs and connected to the outer walls of the two positioning tubes 110. In the embodiment of the present application, by providing four support rods 120 and grouping the four sleeve components 121 in pairs and connecting them to the outer walls of the two positioning tubes 110, the overall performance of the device is improved, the structural strength is increased, and the service life is effectively extended.
[0024] In some embodiments, a stopper 123 is provided at both ends of the support rod 120. The stopper 123 is coaxially arranged with the support rod 120 and has a diameter greater than the diameter of the support rod 120. In the embodiment of the present application, by providing the stopper 123, the stopper 123 can block the sleeve component 121, thereby effectively preventing the sleeve component 121 from sliding out of the end of the support rod 120 and detaching from the support rod 120 during the process of sliding along the support rod 120.
[0025] In some embodiments, at least one of the support rods 120 is provided with a handle 124 for the operator to insert his hand into. In the embodiment of the present application, by providing the handle 124, the operator can conveniently lift the entire device from the handle 124 for transportation.
[0026] In some embodiments, a rubber wear-resistant layer is adhered to the inner side of the fan-shaped movable member 140, and anti-slip protrusions are provided on the surface of the rubber wear-resistant layer. In the embodiments of the present application, through the above settings, the friction between the fan-shaped movable member 140 and the steel to be welded can be increased, further ensuring the stability of the connection between the fan-shaped movable member 140 and the steel to be welded.
[0027] In some embodiments, the socket end 112 of the positioning cylinder 110 extends outward to form a flared mouth. In the embodiments of the present application, by providing the flared mouth, when it is necessary to insert the steel to be welded into the positioning cylinder 110, the insertion operation can be conveniently performed through the flared mouth.
[0028] In some embodiments, more than two reserved threaded holes 151 are provided on the outer side wall of the positioning ring 150, and a handrail rod 152 is screwed on the reserved threaded hole 151, and the axial direction of the handrail rod 152 coincides with the radial direction of the positioning ring 150. In the embodiments of the present application, when it is difficult to rotate the positioning ring 150, the handrail rod 152 can be inserted into the reserved threaded hole 151. At this time, the handrail rod 152 and the positioning ring 150 will form a wheel and axle model. The operator can rotate the positioning ring 150 by pushing the handrail rod 152, which can play a role in saving effort.
[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit them; although the present application has been described in detail with reference to the foregoing embodiments, those of ordinary skill in the art should understand that they can still modify the technical solutions described in the foregoing embodiments, or perform equivalent replacements for some or all of the technical features; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the scope of the technical solutions of the embodiments of the present application, and they should all be covered by the scope of the claims and the description of the present application. In particular, as long as there is no structural conflict, the technical features mentioned in each embodiment can be combined in any way.
