[0002] A steel structure support frame is an important component used to support buildings or other structures. It is usually made of steel and has good durability, strength and stability. Its main function is to bear and transfer structural loads, thereby ensuring the stability and safety of buildings or other structures.
[0003] A search revealed that Chinese Patent Publication No. CN211114959U discloses a weld-free steel structure support frame. The support frame is assembled in a prefabricated manner, which also facilitates the disassembly of the support frame by construction workers. Simply turn the fixing bolts away from the interior of positioning holes one, two, and three, thereby increasing the disassembly speed of the support frame and making it easier to recycle.
[0004] In the above technical solution, the support frame formed by the pre-assembled structure is disassembled through multiple sets of positioning holes. However, each set of positioning holes requires the fixing bolt to be turned out before the support frame can be disassembled, which reduces the disassembly efficiency of the support frame, increases the labor intensity of the operator, and takes a long time to disassemble. This is not conducive to the use of the support frame in situations where frequent disassembly and assembly are required. Therefore, a weld-free steel structure support frame is proposed to solve the above problems. Utility Model Content

[0033] 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.
[0034] Reference Figures 1-3This utility model provides an embodiment of a weld-free steel structure support frame, comprising a steel structure 1, with a steel structure 2 on the outer wall of the steel structure 1. Two sets of each of the steel structures 1 and 2 are provided, and the two sets of steel structures 1 and 2 can be assembled into a complete rectangular structure. Four sets of columns 3 are provided at the bottom of the steel structure 2, arranged in a rectangular array with the center point of the rectangular structure as the axis of symmetry. Ear plates 5 are fixedly connected to the outer wall of the steel structure 1, and two sets of ear plates 5 are provided on the surface of each set of steel structures 1. The ear plates 5 are used in conjunction with bolts 6 to... Steel structure 1 and steel structure 2 are installed and fixed. Bolts 6 are threadedly connected to the inner wall of the ear plate 5. Mounting holes 4 are opened through the surface of steel structure 2. Nuts 7 are threadedly connected to the outer wall of the bolts 6. Insert block 8 is fixedly connected to the bottom of steel structure 1, and insert block 9 is fixedly connected to the bottom of steel structure 2. Each set of steel structure 1 has a set of insert block 8 at both ends, and each set of steel structure 2 has a set of insert block 9 at both ends. Insert block 8 and insert block 9 can be inserted into the interior of the mounting groove 10 after they are fitted together. Mounting groove 10 is opened on the surface of column 3, and fixing components are provided on the surface of column 3.
[0035] Reference Figures 4-6 The outer wall of bolt 6 is threaded to the inner wall of mounting hole 4. The end of steel structure 1 fits into the end of steel structure 2. The fixing component includes a through hole 11, which is opened on the outer wall of insert block 8. The inner wall of through hole 11 is adapted to the outer wall of fixing rod 14. Fixing rod 14 is installed inside through hole 11. Connecting plate 15 is fixedly connected to the end of fixing rod 14. Spring 16 is fixedly connected to the side wall of connecting plate 15. Telescopic rod 17 is fixedly connected to the side wall of connecting plate 15. Spring 16 is sleeved on the outer wall of telescopic rod 17. The fixed end of the telescopic rod 17 is fixedly connected to the inner wall of the mounting groove 10. The outer wall of the column 3 is provided with a connection hole 12. Each set of columns 3 has a set of connection holes 12 on both sides, so that the first insert 8 and the second insert 9 can be inserted into the mounting groove 13 and the fixing rod 14 can be inserted into the connection hole 12. The inner wall of the connection hole 12 is adapted to the outer wall of the fixing rod 14. The inner wall of the first insert 8 is provided with a mounting groove 13. The opening of the mounting groove 13 provides space for the connecting plate 15, the telescopic rod 17 and the spring 16. The structure of the second insert 9 is the same as that of the first insert 8.
[0036] Reference Figure 7An expansion joint 18 is provided on the outer wall of the first insertion block 8. The expansion joint 18 provides a gap for thermal expansion and contraction of the structure. Together with the deformable force of the cellulose board 19 and the anti-slip pad 20, it compensates for the thermal expansion and contraction of the first insertion block 8 and the second insertion block 9. The inner wall of the expansion joint 18 is fixedly connected to the cellulose board 19, and the side wall of the cellulose board 19 is fixedly connected to the anti-slip pad 20. The side wall of the anti-slip pad 20 is in contact with the outer surface of the first insertion block 8. The anti-slip pad 20 can increase the friction when the first insertion block 8 and the second insertion block 9 are in contact, thereby improving their stability when inserted into the mounting groove 10.
[0037] Working principle: Hold steel structure 1 and steel structure 2 with their ends aligned. At this time, the side walls of insert block 8 and insert block 9 are in contact. Insert them into the mounting groove 10. The two sets of fixing rods 14 will be squeezed by the groove wall of the mounting groove 10, which will drive the telescopic rod 17 and spring 16 to stretch to their maximum tension. When insert block 8 and insert block 9 gradually move downwards until the bottom ends of steel structure 1 and steel structure 2 are in contact with the groove opening of the mounting groove 10 and cannot move, the connecting hole 12 and the through hole 11 are aligned. The elastic force of spring 16 rebounds after the squeezing force is removed, and telescopic rod 17 returns to its original position, allowing the fixing rod 14 to be inserted into the connecting groove. The steel structure supports extend from the inner hole 12 to the outer side of the column 3. After the steel structure 1 and steel structure 2 are connected to the column 3, the bolt 6 is screwed into the mounting hole 4 until it extends out from the outer side of the steel structure 2. The bolt 6 is then fixed with the nut 7, completing the quick installation of the steel structure support rod. This avoids the need for welding to connect the steel structure support frame. When it is necessary to disassemble the steel structure support frame, after unscrewing the nut 7 and bolt 6 in the opposite direction, manually press the fixing rod 14 towards the inner side of the column 3. After the fixing rod 14 is disengaged from the connecting hole 12, pull the steel structure 1 or steel structure 2 upwards to disassemble the steel structure support frame for easy storage or transportation.
[0038] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
