Description

Technical Field

[0001] This utility model relates to the field of steel structure component processing technology, and in particular to a deformation-resistant positioning fixture for steel structure components. Background Technology

[0002] Steel structure component positioning fixtures are specialized process equipment designed to meet the processing needs of steel structure components. Their core function is to achieve precise positioning, attitude fixation, and position calibration of steel columns, steel beams, node connectors, and other components in a three-dimensional coordinate system through standardized mechanical structures, positioning references, and locking mechanisms.

[0003] This tooling needs to be customized according to the cross-sectional shape of the component and the assembly accuracy requirements. It can effectively constrain the translation, rotation and other degrees of freedom of the component during the assembly process, avoid the cumulative error and dimensional deviation caused by manual positioning, and reduce the dependence on the skill proficiency of the operators. It significantly improves the consistency, efficiency and construction safety of steel structure assembly. It is an indispensable core auxiliary equipment in modern steel structure industrial production, modular installation and high-precision engineering.

[0004] When hoisting and assembling thin-walled steel structural components for decorative purposes, the contact area between the hoisting equipment and the component is significantly reduced, and the load transfer path is highly concentrated in a localized area. Because thin-walled steel structural components have weak local resistance to concentrated loads, the stress around the contact point under concentrated force can rapidly exceed the yield strength of the steel, leading to irreversible deformations such as localized bulging and axial bending. This type of deformation not only compromises the geometric accuracy of the component, affecting subsequent node alignment and assembly quality, but also impacts the surface flatness of the decorative thin-walled steel structural components. Utility Model Content

[0005] The purpose of this utility model is to solve the problem of bending deformation caused by stress concentration at the contact point between the lifting tool and the component when hoisting and assembling thin-walled steel structure components. Therefore, a deformation-preventing positioning fixture for steel structure components is proposed.

[0006] To achieve the above objectives, the present invention adopts the following technical solution: a deformation-resistant positioning fixture for steel structure components, comprising an operating table, a steel structure adapter being movably engaged in the middle of the operating table, a steel structure main body being movably engaged in both ends of the steel structure adapter, a steel structure positioning component being provided in both ends of the steel structure adapter, and an auxiliary hoisting component being provided on the outer side of the steel structure adapter.

[0007] Preferably, the steel structure adapter includes an adapter frame and several positioning plates. The positioning plates are fixedly connected to both sides of the adapter frame in a centrally symmetrical manner. Several positioning slots are symmetrically opened at both ends of the main steel structure, and the positioning plates are movably engaged inside the positioning slots.

[0008] Preferably, a number of positioning rods are fixedly connected to the middle of the operating table, and one end of each positioning rod extends movably through the side of the adapter frame.

[0009] Preferably, threaded holes are provided on both sides of the adapter frame. The auxiliary hoisting assembly includes two No. 1 threaded rods, two adapter plates, and a No. 2 threaded rod. One end of the two No. 1 threaded rods is threaded into the inside of the threaded hole. The other end of the two No. 1 threaded rods movably passes through one end of the two adapter plates and is threaded with a nut. Both ends of the No. 2 threaded rod movably pass through the other end of the two adapter plates and are threaded with a nut.

[0010] Preferably, a retaining ring is symmetrically fixedly connected to the outer side of the second threaded rod.

[0011] Preferably, the steel structure positioning assembly includes two positioning angle irons, a guide rod, and a lower pressure plate. The two positioning angle irons are fixedly welded to the top surface of the operating table in a centrally symmetrical manner. One end of the guide rod is fixedly connected to one end of the positioning angle iron, and the other end of the guide rod movably passes through one end of the lower pressure plate and is threaded with a nut.

[0012] Preferably, a second retaining ring is fixedly connected to the middle of the first threaded rod.

[0013] Compared with the prior art, the advantages and positive effects of this utility model are as follows:

[0014] 1. In this utility model, by installing auxiliary hoisting components on the outside of the steel structure transition piece, the hook does not directly contact the steel structure main body and the steel structure transition piece when hoisting the steel structure main body and the steel structure transition piece, thus preventing deformation of the steel structure main body and the steel structure transition piece due to localized stress concentration and ensuring the flatness of the appearance of the steel structure main body and the steel structure transition piece.

[0015] 2. In this utility model, two identical steel structure main bodies are initially assembled together by steel structure adapters, and then initially connected by welding. The positioning structure and the weld form a dual constraint system, which not only enhances the shear and tensile bearing capacity of the connection node, but also enables the load to be evenly transferred through the steel structure adapters. This avoids the stress concentration phenomenon that may occur when components are directly connected, and greatly improves the stress stability and durability of the overall structure. It is suitable for scenarios with high requirements for connection accuracy and stability, such as large-span steel structures and modular buildings. Attached Figure Description

[0021] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0022] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0023] Example 1: As Figures 1-4As shown, this utility model provides a deformation-resistant positioning fixture for steel structure components, including an operating platform 1. A steel structure adapter 2 is movably engaged in the middle of the operating platform 1. A steel structure main body 3 is movably engaged at both ends of the steel structure adapter 2. Steel structure positioning components 4 are respectively provided at both ends of the steel structure adapter 2. An auxiliary hoisting component 5 is provided on the outside of the steel structure adapter 2. The steel structure adapter 2 includes an adapter frame 21 and several positioning long plates 22. The several positioning long plates 22 are fixedly connected to both sides of the adapter frame 21 in a centrally symmetrical manner. Several positioning grooves 31 are symmetrically opened at both ends of the steel structure main body 3. The positioning long plates 22 are movably engaged in the interior of the positioning grooves 31. Several positioning long plates 31 are fixedly connected in the middle of the operating platform 1. The main positioning rod 11 has one end movably passing through the side of the adapter frame 21. The adapter frame 21 has threaded holes 211 on both sides. The auxiliary hoisting assembly 5 includes two first threaded rods 51, two adapter plates 52, and a second threaded rod 53. One end of the two first threaded rods 51 is threaded into the inside of the threaded hole 211. The other end of the two first threaded rods 51 movably passes through one end of the two adapter plates 52 and is threaded with a nut. The two ends of the second threaded rod 53 movably pass through the other end of the two adapter plates 52 and are threaded with nuts. A first retaining ring 531 is symmetrically fixedly connected to the outer side of the second threaded rod 53, and a second retaining ring 511 is fixedly connected to the middle of the first threaded rod 51.

[0024] The specific setup and function of this embodiment are described below. The assembler first aligns the adapter frame 21 with the positioning rod 11, allowing the positioning rod 11 to extend into the adapter frame 21 for initial positioning of the steel structure adapter 2. Then, the two main steel structures 3 are placed at both ends of the steel structure adapter 2, and the main steel structures 3 are pushed towards the ends of the steel structure adapter 2. The positioning plate 22 slides in and engages with the positioning groove 31. The assembler uses welding equipment to weld the positioning plate 22 into the positioning groove 31, initially welding the two main steel structures 3 and the steel structure adapter 2 together. Finally, two No. 1 threaded rods 51 are threaded together, with one end threaded into the... The inside of the threaded hole 211 is aligned with the ends of the first threaded rod 51 and the second threaded rod 53, and then the nuts are installed. This completes the installation of the auxiliary hoisting assembly 5. The hoisting equipment hangs the hook on the outside of the second threaded rod 53, completing the pre-hoisting preparation. The first retaining ring 531 can restrain the hook to prevent it from sliding or deviating. When hoisting the main steel structure 3 and the steel structure adapter 2, the hook does not directly contact the main steel structure 3 and the steel structure adapter 2 to prevent deformation of the main steel structure 3 and the steel structure adapter 2 due to localized stress concentration, thus ensuring the flatness of the main steel structure 3 and the steel structure adapter 2.

[0025] Example 2: Figures 1-4As shown, the anti-deformation positioning fixture for steel structure components in this utility model includes an operating table 1. A steel structure adapter 2 is movably connected to the middle of the operating table 1. A steel structure main body 3 is movably connected to both ends of the steel structure adapter 2. A steel structure positioning component 4 is provided at both ends of the steel structure adapter 2. An auxiliary hoisting component 5 is provided on the outside of the steel structure adapter 2. The steel structure positioning component 4 includes two positioning angle irons 41, a guide rod 42, and a lower pressure plate 43. The two positioning angle irons 41 are fixedly welded to the top surface of the operating table 1 in a centrally symmetrical manner. One end of the guide rod 42 is fixedly connected to one end of the positioning angle iron 41, and the other end of the guide rod 42 movably passes through one end of the lower pressure plate 43 and is threaded with a nut.

[0026] The overall effect of this embodiment is that the operator pushes the steel structure body 3 towards the end of the steel structure adapter 2, and the positioning plate 22 slides in and is locked inside the positioning groove 31. The assembly personnel use welding equipment to weld the positioning plate 22 inside the positioning groove 31. The two identical steel structure bodies 3 are initially assembled together through the steel structure adapter 2, and then initially connected by welding. The positioning structure and the weld form a double constraint system, which not only enhances the shear and tensile bearing capacity of the connection node, but also enables the load to be evenly transferred through the steel structure adapter 2, avoiding the stress concentration phenomenon that may occur when components are directly connected. This greatly improves the stress stability and durability of the overall structure, and is suitable for scenarios with high requirements for connection accuracy and stability, such as large-span steel structures and modular buildings.

[0027] The usage and working principle of this device are as follows: First, the assembler aligns the adapter frame 21 with the positioning rod 11, allowing the positioning rod 11 to extend into the interior of the adapter frame 21 to initially position the steel structure adapter 2. Then, the two main steel structures 3 are placed at both ends of the steel structure adapter 2, and the main steel structures 3 are pushed towards the ends of the steel structure adapter 2. The positioning plate 22 slides in and engages with the interior of the positioning groove 31. The assembler uses welding equipment to weld the positioning plate 22 into the interior of the positioning groove 31, initially welding the two main steel structures 3 and the steel structure adapter 2 together. Then, two threaded rods 51 are threaded together, with one end threaded into the threaded hole 211. The ends of the threaded rods 51 and 53 are aligned with the ends of the adapter plate 52. Finally, nuts are threaded together to complete the installation of the auxiliary hoisting component 5. The hoisting equipment hangs the hook on the outside of the 53, completing the pre-hoisting preparation.
