Description

Technical Field

[0001] This utility model relates to the field of civil engineering technology, and in particular to a height-adjustable quick-installation bracket for steel structures. Background Technology

[0002] In the field of civil engineering construction, steel structures are mainly composed of columns, longitudinal beams, transverse beams, purlins, and various types of steel plates and connectors. After design, they are uniformly produced and processed by steel structure manufacturers, transported to the construction site, and assembled on-site by workers, and then hoisted and assembled at high altitude. The connection methods are mainly high-strength bolt connections and welding, with a small part using prefabricated structures.

[0003] Because steel structures are generally smaller in size than similar concrete structures, yet bear greater loads, their fabrication and installation require higher precision, especially in welding. Even a slight deviation in the welding position can alter the stress on the steel structure, causing it to bear loads exceeding the design specifications. In bolted connections, misalignment of the connection position can cause misalignment of pre-drilled holes, preventing bolts from being inserted or tightened to the required torque, thus hindering the assembly and installation of the steel structure or resulting in insufficient connection strength.

[0004] In current installation methods, the components to be installed are lifted by a crane and suspended in the air before installation. At this time, the components are easily affected by wind, thrust, or the lifting and braking operations of the crane, as they have no other support. They are basically in an unstable state, resulting in inaccurate installation positions. This has a great impact on both welding and bolted connections. Therefore, how to quickly, accurately and stably place the components to be installed at the pre-installation height is an urgent problem to be solved. Utility Model Content

[0005] The purpose of this invention is to provide a height-adjustable quick-installation bracket for steel structures, which can quickly, accurately, and stably place the components to be installed at the pre-installation height for installation.

[0012] Furthermore, a limiting support is fixed on the side of the vertical plate that abuts against the fastening knob. The limiting support has a blind hole coaxial with the second threaded hole, and the end of the fastening knob extends into the blind hole to prevent it from radially shifting.

[0013] Furthermore, a reinforcing plate is welded and fixed between the vertical plate and the horizontal plate of the L-shaped support frame.

[0014] Furthermore, the upper surface of the support plate is provided with a first anti-slip structure.

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] The purpose of this invention is to provide a height-adjustable quick-installation bracket for steel structures, which can quickly, accurately, and stably place the components to be installed at the pre-installation height for installation.

[0030] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the present utility model will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0031] like Figures 1-3 As shown, this utility model provides a height-adjustable quick-installation bracket for steel structures, including a support assembly and a load-bearing assembly. The support assembly includes two L-shaped support frames 1, each containing a vertical vertical plate 11 and a horizontally extending horizontal plate 12, with the horizontal plate 12 fixedly connected to the corresponding vertical plate 11. The two vertical plates 11 are clamped to the side wall of the steel structure column by a detachable connection structure. The load-bearing assembly includes a support plate 3 and a positioning rod 31 vertically fixed to the bottom surface of the support plate 3. A first through hole 121 penetrating the thickness of the horizontal plate 12 is provided, and the positioning rod 31 is slidably inserted into the first through hole 121. The support plate 3 is positioned above the horizontal plate 12 and slides in cooperation with the horizontal plate 12. A first threaded hole 13 is provided on the horizontal plate 12, and a height adjustment knob 14 is threadedly connected to it. The vertical height of the support plate 3 is adjusted by abutting the top of the height adjustment knob 14 against the bottom surface of the support plate 3.

[0032] In use, the support components of the mounting bracket are fixed to the side wall of the pre-installation position of the steel structure column through a detachable connection structure. The component to be installed is hoisted and placed on the support plate 3 located on the support components, so that the component to be installed is not in a suspended state. Therefore, the component to be installed is not affected by factors such as wind. By adjusting the height adjustment knob 14, the height of the support plate 3 can be adjusted more precisely, so that the installation height of the component to be installed is more accurate. This allows the component to be installed to be placed quickly, accurately and stably at the pre-installation height. After the hoisting mechanism places the component to be installed on the mounting bracket, it can hoist other components to be installed without continuously occupying the hoisting mechanism resources, which greatly improves the installation efficiency of the steel structure.

[0033] As an example of an implementable approach, such as Figures 1-4As shown, the detachable connection structure includes an adjusting plate 2 and at least two sliding legs 21 vertically fixed to the adjusting plate 2. Each of the two vertical plates 11 has a second through hole 111 penetrating its thickness. The sliding legs 21 correspond one-to-one with the second through holes 111 and slide through them, so that the sliding legs 21 and the two vertical plates 11 form a rectangular frame structure surrounding the steel structure column. A first limiting structure is provided at the end of the sliding leg 21 away from the adjusting plate 2 to limit the displacement of the vertical plate 11. The first limiting structure can be a nut or a limiting pin. A second threaded hole 23 is provided on the adjusting plate 2 and a fastening knob 22 is threadedly connected to it. The end of the fastening knob 22 abuts against the side wall of the vertical plate 11 to drive the two vertical plates 11 to clamp the steel structure column. By setting the first limiting structure, the support assembly can be quickly fitted onto the steel structure column and fastened by the fastening knob 22, effectively improving the installation efficiency of the mounting bracket.

[0034] As an example of an implementable approach, such as Figure 5 As shown, a limiting support 112 is fixed on the side of the vertical plate 11 that abuts against the fastening knob 22. A blind hole coaxial with the second threaded hole 23 is provided in the limiting support 112. The end of the fastening knob 22 is inserted into the blind hole, thereby radially limiting the end of the fastening knob 22 and guiding the axial path of the fastening knob 22 to prevent its radial displacement and improve the stability of the mounting bracket.

[0035] As an example of an implementable approach, such as Figure 1 and 2 As shown, a reinforcing plate 15 is welded and fixed between the vertical plate 11 and the horizontal plate 12 of the L-shaped support frame 1 to improve the strength of the mounting bracket.

[0036] As an example of implementation, a first anti-slip structure and a second anti-slip structure are respectively provided on the upper surface of the support plate 3 and the contact surface between the vertical plate 11 and the steel structure column. The first anti-slip structure and the second anti-slip structure can be anti-slip textures or anti-slip rubber layers to prevent slipping and improve the overall stability.

[0037] As an example of an implementable approach, such as Figures 1-3 As shown, the positioning rod 31 is a cylindrical rod, and at its end away from the support plate 3, there is a second limiting structure located below the horizontal plate 12. The second limiting mechanism can be a nut or a positioning pin to prevent the support plate 3 from falling off, thereby improving the safety of the mounting bracket.

[0038] As an example of an implementable approach, such as Figures 1-4 As shown, there are four sliding legs 21 and four positioning rods 31, which are evenly distributed around the center of gravity of the adjusting plate 2 and the supporting plate 3, respectively, effectively improving the stability of the structure.

[0039] As an example of implementation, a first gear set is provided that is driven to the height adjustment knob 14 and fixed on the side of the adjustment plate 2 away from the sliding leg 21, and a second gear set is provided that is driven to the fastening knob 22 and fixed on the bottom surface of the horizontal plate 12. Both the first gear set and the second gear set are reduction gear sets. The height adjustment knob 14 and the fastening knob 22 are indirectly adjusted through the first gear set and the second gear set respectively, making the adjustment more effortless and the adjustment accuracy higher.

[0040] As an example of implementation, the two L-shaped support frames 1 of the support component are identical in structure and symmetrically arranged, so that there is no need to distinguish them during manufacturing and use, making them more convenient to use and reducing manufacturing costs.

[0041] This utility model uses specific examples to illustrate its principles and implementation methods. The above description of the embodiments is only for the purpose of helping to understand the core idea of ​​this utility model. At the same time, for those skilled in the art, there will be changes in the specific implementation methods and application scope based on the idea of ​​this utility model. Therefore, the content of this specification should not be construed as a limitation of this utility model.
