Description

Technical Field

[0001] The utility model relates to the field of steel structure supports, in particular to a steel structure support that is convenient for installation and disassembly. Background Technique

[0002] A steel structure support is a framework that supports and protects equipment or the main body of a steel structure. This kind of support not only plays a supporting role, but sometimes also provides convenience for operators to move up and down. Common steel structure supports include angle steel supports and H-shaped steel supports. In steel structure projects, the main role of steel supports is to support components such as steel wall skeletons, steel beams, and steel trusses to ensure the stability and safety of the entire structure.

[0003] For existing steel structure supports, most of the crossbars and vertical bars are directly welded and fixed, which is rather troublesome when carried to the erection site. Moreover, once encountering a temporary layout site, after the heavy support is carried to the layout site, the frame is not easy to move, which reduces the usability and has certain limitations.

[0004] Therefore, a steel structure support that is convenient for installation and disassembly is proposed. Content of the Utility Model

[0005] In view of the above problems, the utility model provides a steel structure support that is convenient for installation and disassembly to solve the problems raised in the above background technique.

[0006] The technical solution of the utility model is as follows:

[0007] A steel structure support that is convenient for installation and disassembly includes two opposite columns. Adjusting components are sleeved on the outer surfaces of both columns. A crossbar is detachably connected between the two adjusting components. The crossbar includes a first steel frame and a second steel frame. Symmetrically arranged fixing blocks are fixedly connected to the side wall of one end of the second steel frame close to the first steel frame. A supporting block is hinged to the top of the fixing block, and the end of the supporting block away from the fixing block is fixed to the side wall of the first steel frame.

[0008] The working principle of the above technical solution is as follows:

[0009] Place the two columns at the predetermined installation position and ensure their verticality and stability. Sleeve the adjusting components on the outer surfaces of the columns, then unfold the first steel frame and the second steel frame of the crossbar, and then connect the two ends of the crossbar to the connecting sleeves of the two adjusting components respectively.

[0010] In a further technical solution, the adjusting component includes a sliding sleeve sleeved on the outer surface of the column. A bearing sleeve is fixedly connected to the outer surface of the sliding sleeve. Connecting sleeves are arranged at both ends of the crossbar. A socket that is inserted and matched with the crossbar is opened on the surface of the connecting sleeve. A connecting shaft is fixedly connected to the side surface of the connecting sleeve away from the crossbar, and the outer surface of the connecting shaft is fixedly connected to the inner wall of the bearing sleeve.

[0011] Through the above technical solution, the sliding sleeve can slide up and down on the outer surface of the column, so that the installation height of the cross bar can be flexibly adjusted according to actual needs. The connecting sleeves at both ends of the cross bar are plug-in matched with the cross bar, and the connection and separation are very simple and quick. This enables the operation to be completed quickly when the cross bar needs to be replaced or repaired, saving time and labor costs.

[0012] In a further technical solution, the surface of the column is provided with equidistantly distributed adjustment openings, the outer surface of the sliding sleeve is provided with an opening consistent with the size of the adjustment openings, and the surface of the sliding sleeve is provided with a limit bolt penetrating through the inner wall of the adjustment opening.

[0013] Through the above technical solution, the equidistantly distributed adjustment openings enable the height adjustment of the sliding sleeve on the column to be precisely positioned. When the limit bolt passes through the sliding sleeve and is inserted into the adjustment opening, it can effectively prevent the sliding sleeve from accidentally sliding on the column, thereby enhancing the stability of the entire structure during use.

[0014] In a further technical solution, a symmetrically arranged positioning opening is provided at the bottom of one end of the first steel frame close to the second steel frame, and two relative stabilizing rods are fixedly connected to the bottom of one end of the second steel frame facing the first steel frame, and the end of the stabilizing rod away from the second steel frame is inserted into and cooperated with the positioning opening.

[0015] Through the above technical solution, the insertion and coordination of the stabilizing rod and the positioning port can provide additional support and positioning when the first steel frame and the second steel frame are connected, preventing the two from relative displacement and shaking during use, thereby enhancing the overall structural stability of the crossbar.

[0016] In a further technical solution, a sliding opening is provided on the top of the fixed block close to the first steel frame, a convex bolt is fixedly connected to the inner wall of the sliding opening, and a rotating hole is provided on the end of the support block away from the first steel frame, and the rotating hole is sleeved on the outer surface of the convex bolt.

[0017] Through the above technical solution, the design of the rotating hole sleeve on the outer surface of the convex bolt allows the support block to flexibly rotate around the convex bolt. When the cross bar needs to be unfolded for use, the support block can be easily rotated to the supporting position; when the cross bar needs to be folded and stored, it can be conveniently rotated and stored. When the support block is rotated to the working position, it can provide strong support for the connection between the first steel frame and the second steel frame, enhance the overall load-bearing capacity and stability of the cross bar, and prevent bending and deformation at the connection.

[0018] In a further technical solution, flanges are welded to both upper and lower ends of the column.

[0019] Through the above technical solution, the presence of the flange enables the column to be quickly connected to other structures by bolts during installation, eliminating the need for complex on-site welding, improving the installation efficiency. In addition, the welded flange and the column form an integral body, providing a more stable connection.

[0020] Compared with the prior art, the utility model has the following beneficial effects:

[0021] 1. By providing a detachable connection between the crossbar and the column, the convenient assembly and disassembly of the crossbar and the column are achieved in the form of inserting both ends of the crossbar into the connecting sleeves of the adjusting assembly, solving the problem that most of the crossbars and vertical bars of the existing steel structure brackets are directly welded and fixed, which is rather troublesome when carried to the construction site, and improving the convenience of transportation and carrying.

[0022] 2. By providing a foldable crossbar, in which the first steel frame and the second steel frame cooperate with the stabilizing rod and the positioning port, and the hinge connection between the support block and the fixed block, the flexible deformation of the crossbar is realized in the form of unfolding for use and folding for storage, solving the problem that the existing steel structure brackets are bulky and not easy to store and transport, and further enhancing the convenience and practicality of use.

[0023] 3. By welding flanges at both the upper and lower ends of the column, the convenience and detachability of column installation are achieved in the form of being able to be quickly connected and fixed to the foundation or other structures by bolts, solving the problem of difficult installation and disassembly of the existing steel structure brackets, providing convenience for temporary arrangement and repeated use, and effectively overcoming the limitations of use.

[0033] Embodiment:

[0034] Please refer to Figures 1-4 , a steel structure bracket that is convenient for installation and disassembly, including two opposite columns 1. Adjusting components 3 are sleeved on the outer surfaces of both columns 1. A cross bar 2 is detachably connected between the two adjusting components 3. The cross bar 2 includes a first steel frame 21 and a second steel frame 22. A symmetrically arranged fixing block 25 is fixedly connected to the side wall of one end of the second steel frame 22 close to the first steel frame 21. A support block 26 is hinged to the top of the fixing block 25, and one end of the support block 26 away from the fixing block 25 is fixed to the side wall of the first steel frame 21.

[0035] The working principle of the above technical solution is as follows:

[0036] Place the two columns 1 at the predetermined installation positions and ensure that they are vertical and stable. Sleeve the adjusting components 3 on the outer surfaces of the columns 1, then unfold the first steel frame 21 and the second steel frame 22 of the cross bar 2, and then connect the two ends of the cross bar 2 to the connecting sleeves of the two adjusting components 3 respectively.

[0037] Please refer to Figure 1 and Figure 2, the adjusting assembly 3 includes a sliding sleeve 31 sleeved on the outer surface of the vertical column 1. A bearing sleeve 32 is fixedly connected to the outer surface of the sliding sleeve 31. Connecting sleeves 33 are arranged at both ends of the cross bar 2. A socket 35 for inserting and mating with the cross bar 2 is formed on the surface of the connecting sleeve 33. A connecting shaft 34 is fixedly connected to the side surface of the connecting sleeve 33 away from the cross bar 2. The outer surface of the connecting shaft 34 is fixedly connected to the inner wall of the bearing sleeve 32.

[0038] The sliding sleeve 31 can slide up and down on the outer surface of the vertical column 1, so that the installation height of the cross bar 2 can be flexibly adjusted according to actual needs. The connecting sleeves 33 at both ends of the cross bar 2 are inserted and mated with the cross bar 2. The connection and separation are very simple and fast, which enables the operation to be completed quickly when the cross bar needs to be replaced or repaired, saving time and labor costs.

[0039] Please refer to Figure 1 and Figure 2 , adjustment openings 36 are equidistantly distributed on the surface of the vertical column 1. An opening with the same size as the adjustment opening 36 is formed on the outer surface of the sliding sleeve 31. A limiting bolt 37 is inserted through the surface of the sliding sleeve 31 and penetrates to the inner wall of the adjustment opening 36.

[0040] The equidistantly distributed adjustment openings 36 enable precise positioning of the height adjustment of the sliding sleeve 31 on the vertical column 1. When the limiting bolt 37 passes through the sliding sleeve 31 and inserts into the adjustment opening 36, it can effectively prevent the sliding sleeve 31 from accidentally sliding on the vertical column 1, thereby enhancing the stability of the entire structure during use.

[0041] Please refer to Figure 2 and Figure 3 , symmetrically arranged positioning openings 24 are formed at the bottom of one end of the first steel frame 21 close to the second steel frame 22. Two opposite stabilizing rods 23 are fixedly connected to the bottom of one end of the second steel frame 22 facing the first steel frame 21. The end of the stabilizing rod 23 away from the second steel frame 22 is inserted and mated with the positioning opening 24.

[0042] The insertion and mating of the stabilizing rod 23 and the positioning opening 24 can provide additional support and positioning when the first steel frame 21 and the second steel frame 22 are connected, preventing relative displacement and shaking between the two during use, and enhancing the structural stability of the entire cross bar.

[0043] Please refer to Figure 3 and Figure 4 , a sliding opening 27 is formed at the top of the fixed block 25 on the side close to the first steel frame 21. A convex bolt 28 is fixedly connected to the inner wall of the sliding opening 27. A rotating hole 29 is formed at the end of the support block 26 away from the first steel frame 21. The rotating hole 29 is sleeved on the outer surface of the convex bolt 28.

[0044] The design of the 29 sets of rotating holes sleeved on the outer surface of the convex bolt 28 enables the support block 26 to rotate flexibly around the convex bolt 28. When the crossbar 2 needs to be unfolded and used, the support block 26 can easily rotate to the support position; when the crossbar 2 needs to be folded and stored, it can be conveniently rotated and retracted. When the support block 26 rotates to the working position, it can provide strong support for the connection between the first steel frame 21 and the second steel frame 22, enhancing the overall load-bearing capacity and stability of the crossbar and preventing bending and deformation at the connection.

[0045] Please refer to Figure 1 , flange plates 4 are welded to both the upper and lower ends of the column 1.

[0046] The presence of the flange plates 4 enables the column 1 to be quickly connected to other structures by bolts during installation, eliminating the need for complex on-site welding and improving the installation efficiency. In addition, the welded flange plates 4 and the column 1 form an integral whole, providing a more stable connection.

[0047] During operation, first disassemble the whole that needs to be carried, and release the connection between the two ends of the crossbar 2 and the connection sleeve 33 of the adjustment component 3. During installation, rotate the support block 26 around the convex bolt 28 at the top of the fixed block 25 to make the first steel frame 21 and the second steel frame 22 approach each other relatively, and insert the stabilizing rod 23 on the second steel frame 22 into the positioning port 24 at the bottom of the first steel frame 21 to ensure the stability of the connection. Then connect the remote ends of the unfolded first steel frame 21 and the second steel frame 22 to the connection sleeve 33. Subsequently, loosen the limit bolt 37 on the sliding sleeve 31, slide the sliding sleeve 31 down along the column 1 to the required position, and re-insert the limit bolt 37 to fix it. Then fix the two columns 1 at the installation position through the flange plates 4 at their upper and lower ends for use.

[0048] The above embodiments only represent the specific implementation manners of the present utility model, and the description is relatively specific and detailed, but it should not be construed as a limitation to the scope of the patent of the present utility model. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present utility model, several modifications and improvements can still be made, and these all belong to the protection scope of the present utility model.
