Description

Technical Field

[0001] This utility model relates to the field of steel structure construction assistance, specifically to a temporary support frame for steel structure assembly. Background Technology

[0002] In the critical construction phase of steel structure engineering, from component processing to overall forming, whether it is the aerial connection of core load-bearing components such as steel columns and steel beams, or the on-site assembly of complex combined components such as steel trusses and steel space frames, the assembly operation often cannot rely solely on the components themselves to complete precise positioning and stable placement. Therefore, temporary support devices are often needed to ensure the positioning accuracy of the components and construction safety.

[0003] Comparing this to Chinese patent CN 222919918U, which discloses a steel structure frame, the frame includes a main body; a top support structure disposed on the top of the main body; two sets of first reinforcing structures, each including multiple first inclined beams and multiple parallel first horizontal beams arranged vertically, the first horizontal beams including a first end and a second end arranged opposite each other; two sets of second reinforcing structures, each including multiple second inclined beams and multiple parallel second horizontal beams arranged vertically, the second horizontal beams including a first end and a second end arranged opposite each other; and multiple layers of third reinforcing structures arranged vertically along the main body, each third reinforcing structure including two cross-arranged and interconnected support horizontal beams on a horizontal plane, the two ends of each support horizontal beam being connected to two vertical beams at opposite corners; In the aforementioned steel structure jig, the first reinforcing structure consists of multiple first diagonal beams and first crossbeams fixedly connected, such as by welding or bolting; the second reinforcing structure is similarly constructed. Furthermore, the multi-layered third reinforcing structure requires bolting to each of the diagonal vertical beams. This "multi-component fixed connection" structure necessitates the positioning and fastening of numerous crossbeams and diagonal beams during jig assembly, and the disassembly process requires the individual disassembly of connecting parts. This cumbersome operation and inconvenient adjustment, especially when welded, results in a large overall jig size, making it difficult to store and causing storage challenges.

[0004] To address the aforementioned issues, there is an urgent need to design a temporary support frame that is easy to install and store, in order to meet the diverse needs of steel structure assembly construction and improve construction efficiency and safety. Utility Model Content

[0005] The purpose of this utility model is to provide a temporary support frame for steel structure assembly, so as to solve the defects of the existing temporary support frame that is cumbersome to install and difficult to store.

[0006] The purpose of this utility model is achieved as follows: This utility model provides a temporary support frame for steel structure assembly, including uprights, with no fewer than two uprights spaced apart. The bottom of each upright is provided with a lower support frame for auxiliary support, and the top of each upright is provided with an upper support frame. Both the lower support frame and the upper support frame can be folded onto the outer wall of the upright.

[0008] As an optional solution to the technical solution in this application, the support frame includes a double-threaded rod with threaded sections at both ends in opposite directions. The outer sides of the two threaded sections are respectively threaded to two columns, and the lower support frame and the upper support frame are respectively installed on the outer sides of the two columns.

[0009] As an optional solution to the technical solution in this application, the double-threaded rod is provided with a rotating rod in the middle for assisting rotation.

[0010] As an optional solution to the technical solution of this application, the lower support frame has the same structure as the upper support frame and is arranged symmetrically in the upper and lower parts.

[0011] As an optional solution to the technical solution of this application, the upper support frame includes an upper support rod rotatably located at the top of the column. There are at least two upper support rods, evenly distributed on the outer side of the column. An upper support rod corresponding to the upper support rod is rotatably connected to the outer side of the column. When the upper support rod rotates to be perpendicular to the column above, the movable end of the upper support rod abuts against the upper support rod for a fixed limit. The lower support frame includes a lower support rod rotatably located at the bottom of the column. There are at least two lower support rods, evenly distributed on the outer side of the column. A lower support rod corresponding to the lower support rod is rotatably connected to the outer side of the column. When the lower support rod rotates to be perpendicular to the column below, the movable end of the lower support rod abuts against the lower support rod for a fixed limit.

[0017] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0018] First embodiment: See Figures 1-6As shown, this utility model provides a temporary support frame for steel structure assembly, including uprights 1, with no fewer than two uprights 1. During actual installation, they need to be arranged in a spaced-out manner. Multiple uprights 1 provide coordinated vertical support. To further enhance its support stability and applicability, a lower support frame 3 is installed at the bottom of the uprights 1. The main function of the lower support frame 3 is to assist the uprights 1 in achieving more stable support. By contacting the ground or the underlying foundation structure, it expands the support area of ​​the uprights 1, reducing the risk of tilting or displacement due to concentrated force. An upper support frame 4 is installed at the top of the uprights 1. The upper support frame 4 serves as a load-bearing transition structure at the top of the uprights 1 and is used to connect with the top plate 2. Furthermore, considering the convenience of storage and transportation of the temporary support frame when not in use, both the lower support frame 3 and the upper support frame 4 are foldable structures. When not in use, they can be folded towards the outer wall of the uprights 1 for storage, thereby significantly reducing the space occupied by the entire frame. In addition, the top plate 2 is a load-bearing component that directly contacts the steel structure to be assembled and bears the weight of the steel structure. Its installation is related to the state of the upper support frame 4. Only after all the upper support frames 4 on the top of all the uprights 1 have been extended to the preset working position can the top plate 2 be placed on the upper support frame 4. Furthermore, the bottom of the top plate 2 is fixed to the top surface of the upper support frame 4 on multiple uprights 1 in a detachable connection manner. This detachable connection structure not only facilitates the installation and disassembly of the top plate 2, but also makes it easy to replace the appropriate top plate 2 according to the assembly requirements of different steel structures. It also allows for individual inspection and repair by disassembling the top plate 2 when a problem occurs with a single upright or upper support frame, thereby improving the flexibility of use and the convenience of maintenance of the entire temporary support frame.

[0019] The second embodiment differs from the first embodiment in that: In a preferred embodiment, there are two uprights 1, located near the two ends of the top plate 2 along its length. This allows the steel structure load borne by the top plate 2 to be distributed more evenly to the two uprights 1, avoiding load imbalance caused by the uprights 1 being concentrated in the middle or on one side of the top plate 2. This prevents the top plate 2 from bending or deforming or the uprights 1 from being overloaded, thus providing a basic guarantee for the stability of the entire support structure. When there are no less than three uprights 1, they can be evenly distributed at the bottom of the top plate 2 to achieve a uniform distribution of the load and improve the support effect on the top plate 2. The support frame 1 includes a double threaded rod 101, which is vertically arranged. The two ends of the double threaded rod 101 are machined with threaded sections with opposite directions of rotation. On the outside of these two opposite threads, two columns 102 are respectively assembled by threaded connection. When the two columns 102 are kept in a relatively fixed state, when the double threaded rod 101 is rotated, the two columns 102 can move towards or away from each other along the axial direction of the double threaded rod 101, that is, the columns 102 move closer to each other or further away from each other, so as to adjust the overall height of the support frame 1 by lowering or raising it. Based on the above structure, the lower support frame 3 and the upper support frame 4 are respectively installed on the outer side of the two columns 102. That is, the lower support frame 3 is installed on the column 102 below the double threaded rod 101, and the upper support frame 4 is installed on the column 102 above the double threaded rod 101. The rotational movement of the column 102 can synchronously drive the lower support frame 3 and the upper support frame 4 to adjust their positions, providing the possibility for subsequent overall height adjustment of the upright frame 1 and adaptation of the support structure. Furthermore, a rotating rod for assisting rotation is provided at the middle position of the double threaded rod 101. The function of this rotating rod is to provide the operator with a convenient point of force application. Without the need for additional large tools, the double threaded rod 101 can be driven to rotate simply by rotating this rotating rod, thereby controlling the relative movement of the two columns 102. Ultimately, this enables operations such as adjusting the height of the upright 1 and adapting the positions of the lower support frame 3 and the upper support frame 4, significantly improving the convenience and efficiency of structural adjustment of the upright 1 and reducing the difficulty of on-site operation.

[0020] The third embodiment differs from the first embodiment in that: This "identical structure and symmetrical arrangement" can simplify the production process, reduce the structural and manufacturing costs of parts, and reduce the difficulty of inventory management for different specifications of parts. On the other hand, it can ensure that the support structure at both ends of the upright 1 has the same stress logic, making the support stability of the entire upright 1 more balanced. Preferably, the structural dimensions of the lower support frame 3 are larger than those of the upper support frame 4. In this case, the lower support frame 3 provides a wider "foothold" for the entire upright frame 1, expands the grounding area, optimizes the load distribution, and thus improves its stability.

[0021] In the upper support frame 4, the upper support frame 4 includes an upper support rod 402, which is rotatably connected to the top of the column 102 located on the upper part of the upright frame 1. The upper support rod 402 can rotate around the column 102 to achieve unfolding and folding actions. To ensure support strength, the number of upper support rods 402 is set to no less than two, and they are evenly distributed on the outside of the column 102. This distribution allows the upper support rods 402 to evenly bear the load transmitted by the top plate 2 after unfolding, avoiding localized stress concentration. Simultaneously, a rotatably connected element to the upper support rod 402 is also rotatably connected to the outside of the column 102. 2. The upper support rod 401 corresponds to the upper support rod 402. The function of the upper support rod 401 is to fix and limit the unfolded state of the upper support rod 402. When the operator rotates the upper support rod 402 to a state perpendicular to the upper column 102, the preset support position is reached. The rotation angle of the upper support rod 401 can be adjusted so that its movable end abuts against a specific position of the upper support rod 402. The supporting force of the upper support rod 401 restricts the downward rotation of the upper support rod 402, thereby ensuring that the upper support rod 402 is stably kept in the working position. Multiple upper support rods 402 form a support plane for supporting the top plate 2. The lower support frame 3 has the same structure as the upper support frame 4. The lower support frame 3 includes a lower support rod 302, which is rotatably connected to the bottom end of the column 102 located at the lower part of the upright frame 1. It can also be unfolded and folded. There are no less than two lower support rods 302, which are evenly distributed on the outside of the column 102 to ensure that the bottom of the upright frame 1 is evenly stressed when it comes into contact with the ground or foundation structure, thereby improving the overall stability of the upright frame 1. In addition, the lower support rods 301, which correspond one-to-one with the lower support rods 302, are also rotatably connected to the outside of the lower column 102. When the lower support rod 302 is rotated to be perpendicular to the lower column 102, the preset support position is reached. By adjusting the lower support rod 301 so that its movable end abuts against the lower support rod 302, the lower support rod 302 is prevented from rotating under stress through the limiting effect of the lower support rod 301, thus ensuring that the lower support frame 3 continuously provides stable bottom support for the upright frame 1.

[0022] To achieve stable and precise assembly between the upper support rod 402 and the top plate 2, upper insertion holes 403 are machined on the surface of the upper support rod 402, and corresponding top insertion blocks are provided at the bottom of the top plate 2. This plug-in structure can quickly achieve the positioning and installation of the top plate 2 and the upper support rod 402, preventing the top plate 2 from shifting during placement and ensuring that the bottom of the top plate 2 can accurately align with the top surfaces of the upper support rods 402 of the multiple uprights 1. On the other hand, the plug-in structure can limit the top plate 2 in the horizontal direction, preventing the top plate 2 from sliding horizontally when bearing the assembly load of the steel structure, further improving the stability of the connection between the top plate 2 and the upper support frame 4, and ensuring the safety during the steel structure assembly process.

[0023] Consistent with the structural logic of the upper support rod 402, a lower insertion hole is machined on the surface of the lower support rod 302. The device also includes a base plate 5 located below the lower support rod 302, and a bottom insertion block adapted to the lower insertion hole is provided on the base plate 5. The addition of the base plate 5 can increase the contact area between the entire jig and the ground or foundation structure, reduce the pressure of the upright 1 on the ground, and prevent the jig from sinking due to insufficient ground bearing capacity. It can realize the quick positioning and assembly of the lower support rod 302 and the base plate 5, ensure that multiple lower support rods 302 are evenly distributed on the base plate 5, and limit the relative sliding between the lower support rod 302 and the base plate 5 in the horizontal direction, so that the lower support frame 3 can transmit the supporting force more stably through the base plate 5, further enhancing the bottom stability of the entire temporary support jig. Meanwhile, in the structure of the device, since the top plate 2 and bottom plate 5 are respectively used to limit the top and bottom of the multiple uprights 1, the upper and lower columns 102 are limited, so the height of the uprights 1 can be easily adjusted by rotating the double threaded rod 101.

[0024] At the movable ends of the lower support rod 302 and the upper support rod 402, there are vertical ends arranged in opposite directions. Here, "opposite" means that the orientation of the vertical ends forms a specific angle with the main extension direction of the support rods 302 and 402. The lower support rod 302 and its own vertical end, and the upper support rod 402 and its own vertical end, will naturally form a "folded section". This folded section is not a sharp angle, but a contact structure with a certain bearing area, which can provide a stable contact support point for the end of the support rod. At the movable ends of the lower support rod 301 and the upper support rod 401, inserts are integrally formed or fixedly installed. The shape and size of the inserts are adapted to the structure of the folded section, ensuring that the inserts can tightly fit the surface of the folded section. When the support rods 302 and 402 are rotated to the working position perpendicular to the column 102, the operator rotates the corresponding support rods 301 and 401 so that the inserts at the movable ends of the support rods 301 and 401 just abut against the folded section of the support rod. At this time, the fit between the inserts and the folded section will form a... The "triangular support structure" consists of a strut, a support rod, and a column forming a triangle. Utilizing the stability principle of a triangle, the load borne by the support rods 302 and 402 is distributed to the column 102 through the struts 301 and 401. The load borne by the support rods 302 and 402 is the pressure transmitted from the top plate 2 to the upper support rod 402 and the pressure transmitted from the lower support rod 302 to the bottom plate 5, ensuring that the support rods always remain in their working positions and providing crucial structural protection for the stability of the entire temporary support frame.

[0025] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
