Description

Technical Field

[0001] This utility model relates to the field of steel structure technology, specifically a modular steel structure support frame. Background Technology

[0002] Beams, bridges, and other structural elements are important components of modern building products. Since beam bridges are suspended across the ground, a support frame needs to be erected under the beams during construction to support the reinforced concrete components.

[0003] However, in our actual operation, we found that the support frame is composed of multiple components. For the convenience of transportation, multiple components need to be disassembled into independent individuals before transportation. When it is necessary to assemble, multiple components are connected into one piece using bolts. After use, multiple components are disassembled into independent individuals for transportation. Such assembly operation and method is very troublesome. Moreover, the height of the support frame is fixed, and a support frame of a specific height needs to be customized according to the height of the beam or bridge, which makes the adaptability of the support frame not high.

[0004] To address this, a modular steel structure support frame is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a modular steel structure support frame, which solves the problems mentioned in the background art by setting up two relatively sliding uprights and adjusting the height of the upright.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A modular steel structure support frame includes a first upright and a second upright. The bottom of the first upright is fixedly installed with a base. The first upright has a sliding groove. The second upright is slidably disposed in the sliding groove. The top of the second upright is fixedly installed with a top sleeve. Both ends of the top sleeve are rotatably installed with crossbars. The side wall of the first upright has multiple limiting holes, and the second upright also has corresponding limiting holes.

[0007] Preferably, each of the crossbars is fixedly connected to a hinge seat on its bottom wall, a rotating shaft is rotatably mounted on the hinge seat, a reinforcing rib is fixedly connected to the rotating shaft, and a mounting plate is fixedly connected to the end of the reinforcing rib facing away from the rotating shaft. The second upright has a corresponding mounting hole, and the mounting plate is fixedly mounted on the mounting hole by bolts.

[0008] Preferably, both ends of the top sleeve are provided with mounting grooves, and one end of the crossbar is rotatably mounted in the mounting groove via a support shaft.

[0009] Preferably, a limit block is movably installed on each limit hole.

[0010] Preferably, a push rod is fixedly connected to the side wall of the second upright.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. Two uprights are provided, which can slide relative to each other. Uprights one, uprights two, reinforcing ribs, top sleeves, crossbars, hinged seats, mounting plates, etc. constitute a steel structure support frame module. The crossbars are rotatably installed on the top of uprights two, so that the crossbars can be rotated to reduce the lateral area during handling, making the entire support frame module easy to handle and transport. Push rods and limit holes one and two are also provided. The push rods push uprights two to move, thereby adjusting the overall height of the support frame, and the limit blocks are used to support and limit uprights two. Attached Figure Description

[0016] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the stated features. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified. Furthermore, the terms "installed," "connected," and "linked" should be interpreted broadly; for example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0017] Please see Figures 1 to 3 This utility model provides a modular steel structure support frame, the technical solution of which is as follows: A modular steel structure support frame includes a first upright 1 and a second upright 2. A base 7 is fixedly installed at the bottom of the first upright 1. A sliding groove 10 is provided on the first upright 1. The second upright 2 is slidably disposed in the sliding groove 10. A top sleeve 4 is fixedly installed at the top of the second upright 2. A crossbar 5 is rotatably installed at both ends of the top sleeve 4. Multiple limiting holes 8-1 are provided on the side wall of the first upright 1. Corresponding limiting holes 8-2 are also provided on the second upright 2.

[0018] The spacing between each limiting hole 8-1 is the same as the spacing between each limiting hole 8-2, and the size of each limiting hole 8-1 is equal to the size of each limiting hole 8-2.

[0019] like Figure 2 and Figure 3 As shown, a hinge seat 6 is fixedly connected to the bottom wall of each crossbar 5. A rotating shaft 12 is rotatably mounted on the hinge seat 6. A reinforcing rib 3 is fixedly connected to the rotating shaft 12. A mounting plate 11 is fixedly connected to the end of the reinforcing rib 3 away from the rotating shaft 12. A corresponding mounting hole is opened on the upright 2. The mounting plate 11 is fixedly mounted on the mounting hole by bolts.

[0020] The mounting plate 11 and the reinforcing rib 3 are inclined together, and the reinforcing rib 3, the crossbar 5, and the upright 2 form a stable triangular structure. When the device is ready for transport after use, unscrew the bolts on the mounting plate 11 to rotate the crossbar 5 downwards, reducing the angle between the crossbar 5 and the upright 2, making the overall support frame nearly straight, which is convenient for manual handling and allows for easy transport without disassembling the crossbar 5.

[0021] Both ends of the top sleeve 4 are provided with mounting grooves, and one end of the crossbar 5 is rotatably installed in the mounting groove via a support shaft.

[0022] Each limiting hole 8 is movably installed with a limiting block 9, which is cuboid in shape. The limiting block 9 passes through the limiting hole 8 and the limiting hole 8 and supports the upright 2. When the support frame needs to be disassembled, the side of the limiting block 9 is struck with a hammer to disengage it from the limiting hole 8 and the limiting hole 8, thereby removing the support for the upright 2 and allowing the upright 2 to slide downward.

[0023] To support the stability and load-bearing capacity of the structure, multiple limit blocks 9 can be inserted simultaneously.

[0024] A push rod is fixedly connected to the side wall of the second upright 2. When it is necessary to adjust the height of the second upright 2, push the push rod upward to move the second upright 2 upward as well. Then insert the limiting block 9 into the limiting hole 81 and the limiting hole 82 to complete the height adjustment.

[0025] The aforementioned pole 1, pole 2, reinforcing rib 3, top sleeve 4, crossbar 5, hinge seat 6, mounting plate 11, etc. constitute a steel structure support frame module. In actual use, multiple modular support frames are set up side by side to support the bridge or beam to be constructed.

[0026] The entire module can be moved as a whole during handling and transportation without repeated disassembly.

[0027] It is worth noting that when constructing bridges or beams, large formwork is first placed on top of multiple spaced-apart support frames, and then concrete is laid on the formwork and left to solidify.

[0028] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
