Description

Technical Field

[0001] This utility model relates to the field of steel structure component technology, and in particular to a buckling-resistant steel structure component. Background Technology

[0002] Steel structures are structural forms that can bear and transmit loads, using steel materials such as steel plates, hot-rolled, cold-formed, or welded steel sections, connected by connectors. They are one of the main types of building structures, consisting of steel beams, steel columns, steel trusses, and other components made of steel sections and steel plates. The components or parts are connected by welds, bolts, or rivets. Steel structures are relatively lightweight and easy to construct, and are widely used in large factories, stadiums, high-rise buildings, and other fields.

[0003] In actual use, the following shortcomings were found in this device:

[0004] Buckling instability failure is a major form of damage to steel structure components during their use. It usually occurs suddenly and can cause serious losses. The main methods for strengthening steel structures during construction include component replacement, load reduction, structural system modification, increasing component cross-section and connection strength, and prestressed cables. These methods all have their applicable conditions and scope. Some are difficult to meet the requirements of construction and use, such as the troublesome installation process and complicated installation steps of some structural components, which are not conducive to use.

[0005] Therefore, this application provides buckling-resistant steel structural components to meet the requirements. Utility Model Content

[0006] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a buckling-resistant steel structure component.

[0007] To solve the above-mentioned technical problems, this utility model provides the following technical solution:

[0008] A buckling-resistant steel structure component includes a column, with a crossbeam fixedly connected to the top of the column around its perimeter. A support component is provided on the surface of the column, and a positioning frame is provided on the top of the support component. An installation block is fixedly connected to the top of the positioning frame, and a screw is threadedly connected to the top of the installation block. A rotating sleeve and a movable sleeve are sequentially fitted on the surface of the screw from top to bottom. The surface of the movable sleeve is slidably connected to a rotating ring. Clamping plates are fixedly connected to the front and rear sides of the rotating ring. Corner braces are fixedly connected to both sides of the rotating sleeve, and the side of the corner brace away from the rotating sleeve is fixedly connected to the crossbeam by a fastener.

[0009] Preferably, the lifting assembly includes two positioning shells, the rear sides of which are movably connected by a pivot. Strong magnets are fixedly connected to opposite sides of the two positioning shells. A long rod bolt is provided on the right side of the front side of the column. The left side of the long rod bolt passes through one of the positioning shells and is threadedly connected to a threaded sleeve. The rear side of the threaded sleeve is fixedly connected to the other positioning shell.

[0010] Preferably, a knob is fixedly connected to the right side of the long rod bolt, the surface of the knob is provided with anti-slip texture, a handle is fixedly connected to the front side of the opposite side of the two positioning shells, and a support plate is fixedly connected to the top of the opposite side of the two positioning shells. The top of the support plate is fixedly connected to the positioning frame by the first bolt.

[0011] Preferably, the top of both the front and rear sides of the column is fixedly connected with a reinforcing connector, and the bottom of the reinforcing connector is fixedly connected to the crossbeam.

[0012] Preferably, the positioning frame has an installation notch on its left side, and the two clamping plates each have a fitting groove on their opposite sides.

[0013] Preferably, the top and bottom of the rotating sleeve surface are slidably connected to rotating rings, and the opposite sides of the two corner supports are respectively fixedly connected to the two rotating rings.

[0014] Preferably, the inner wall of the movable sleeve is threaded to the screw, and the surface of the movable sleeve is provided with an annular groove for use with the rotating ring.

[0015] Preferably, the top and bottom of the fastener are fixedly connected to the crossbeam and the corner brace by the second bolts, and the front and rear sides of the rotating ring are fixedly connected to the clamping plate by the third bolts.

[0016] Compared with the prior art, this utility model has at least the following beneficial effects:

[0017] In the above solution, two rotatable corner braces allow the beam to be folded before buckling reinforcement, facilitating installation in various confined spaces. During buckling reinforcement, the two corner braces are unfolded and connected to the beam via fasteners. Rotating the rotating sleeve controls the upward movement of two clamps, which limit the corner braces. Workers can then remove the third bolt and weld the two clamps to the corner braces, improving the reinforcement effect. Furthermore, the installation process eliminates the need for manual support and prevents the corner braces from falling, simplifying installation and enhancing safety.

[0018] In the above solution, the positioning frame is supported by two support plates, so that the corner brace does not require manual support from the workers during installation and is fixed in the installation position. The steel structure will not fall when the workers are working at height. Two strong magnets can limit the two positioning shells. The two positioning shells can be fixed to the column by using long bolts and threaded sleeves, so that they can stably support the positioning frame and corner brace, making it convenient for workers to weld and install them.

A rotating sleeve 7 and a movable sleeve 8 are sequentially fitted on the surface of the screw 6 from top to bottom. The surface of the movable sleeve 8 is slidably connected to the rotating ring 9. The rotating ring 9 facilitates the installation of the clamping plate 10. The clamping plate 10 is fixedly connected to both the front and rear sides of the rotating ring 9. The clamping plate 10 can position and fix the two corner supports 11, so that it can strengthen the crossbeam 2 against buckling. The two sides of the rotating sleeve 7 are fixedly connected to the corner supports 11. The side of the corner support 11 away from the rotating sleeve 7 is fixedly connected to the crossbeam 2 through the fastener 12. The fastener 12 can increase the stability of the fixation between the corner support 11 and the crossbeam 2.

[0030] As one embodiment of this utility model, refer to Figure 1 , Figure 2 and Figure 3The lifting assembly 3 includes two positioning shells 301, which can be used to position and fix the positioning frame 4 via two support plates 306. The rear sides of the two positioning shells 301 are movably connected by a pivot, which allows the two positioning shells 301 to be easily opened or closed. Strong magnets 302 are fixedly connected to opposite sides of the two positioning shells 301, which can attach the two positioning shells 301 to the surface of the column 1. A long bolt 303 is provided on the right side of the front side of the column 1. The left side of the long bolt 303 passes through one of the positioning shells 301 and is threadedly connected to a threaded sleeve 304. The long bolt 303 and the threaded sleeve 304 can bring the two positioning shells 301 closer together, so that they can be positioned and fixed by the support plates 306. The positioning frame 4 is supported, and the rear side of the threaded sleeve 304 is fixedly connected to another positioning shell 301. A knob 305 is fixedly connected to the right side of the long rod bolt 303. The long rod bolt 303 can be easily rotated by the operator through the knob 305. The surface of the knob 305 is provided with anti-slip texture. The front side of the opposite side of the two positioning shells 301 is fixedly connected to the handle. The operator can easily remove or install the positioning shell 301 through the handle. The top of the opposite side of the two positioning shells 301 is fixedly connected to the support plate 306. The support plate 306 can support the positioning frame 4 and place it in the installation position of the crossbeam 2, which is convenient for the operator to install and fix the corner support 11. The top of the support plate 306 is fixedly connected to the positioning frame 4 by the first bolt.

[0031] As one embodiment of this utility model, refer to Figure 1 , Figure 2 , Figure 4 and Figure 5 The top of the front and rear sides of the column 1 are fixedly connected with reinforcing connectors. The bottom of the reinforcing connectors is fixedly connected to the crossbeam 2. The reinforcing connectors increase the stability of the connection between the crossbeam 2 and the column 1. The left side of the positioning frame 4 has an installation notch, which allows the positioning frame 4 to be removed after the corner brace 11 is installed. The two clamping plates 10 have fitting grooves on opposite sides. The fitting grooves increase the contact area between the clamping plates 10 and the corner brace 11, increasing the stability after welding. The top and bottom of the rotating sleeve 7 are slidably connected with rotating rings, which facilitate the connection between the two corner braces 11. 1. The two corner supports 11 are fixedly connected to the two rotating rings on opposite sides. The inner wall of the movable sleeve 8 is threadedly connected to the screw 6. The surface of the movable sleeve 8 is provided with an annular groove that cooperates with the rotating ring 9. The annular groove allows the rotating ring 9 to rotate easily. The top and bottom of the fixing member 12 are fixedly connected to the crossbeam 2 and the corner supports 11 by the second bolt. The second bolt allows the fixing member 12 to connect the crossbeam 2 and the corner supports 11 to each other. The front and rear sides of the rotating ring 9 are fixedly connected to the clamping plate 10 by the third bolt. The third bolt allows the rotating ring 9 to be installed and removed from the clamping plate 10 easily.

[0032] Working principle: The positioning frame 4 is placed on the surface of the column 1, and two positioning shells 301 are fixed at the bottom of the positioning frame 4. The positioning shells 301 are attached to the surface of the column 1 by two strong magnets 302. The positioning shells 301 are pushed upward so that they are located at the bottom of the crossbeam 2. The long rod bolt 303 is connected to the threaded sleeve 304 by rotating the knob 305. At the same time, the two positioning shells 301 clamp and fix the column 1. The positioning frame 4 is supported by the support plate 306 installed on one side of the positioning shell 301. This allows the workers to install the corner brace 11 without using their hands, and the corner brace 11 will not fall during the installation process, improving the safety of construction.

[0033] By opening the two folded corner braces 11 and rotating one side of them into the crossbeam 2, the corner braces 11 are connected to the crossbeam 2 through the fastener 12. Then, the movable sleeve 8 is rotated, and the movable sleeve 8 cooperates with the screw 6 to drive the two clamping plates 10 to move upward. The two clamping plates 10 are used to position and fix the two corner braces 11. The workers use a welding gun to connect the two clamping plates 10 to the two corner braces 11. After removing the third bolt, the long rod bolt 303 is reversed, causing the positioning shell 301 and the support plate 306 to move downward. The movement of the support plate 306 causes the positioning frame 4 and the screw 6 to move downward. The positioning shell 301 and the positioning frame 4 are removed to complete the installation of the buckling-resistant reinforcement corner brace 11. Since the corner brace 11 is in a folded state before installation, it is convenient to carry out construction in a narrow area, and the whole installation process is quick and convenient, without the need for workers to manually support the corner brace 11.
