Description

Technical Field

[0001] The present invention relates to the technical field of steel structures, and in particular to an assembled building steel structure. Background Art

[0002] Prefabricated building steel structure is a modern construction method with excellent earthquake and wind resistance. It can provide strong support for prefabricated buildings and ensure the stability of the overall structure. This feature makes prefabricated buildings safer when resisting natural disasters. At the same time, since prefabricated building steel structure can be prefabricated in the factory, it not only saves construction site, but also avoids the pollution of the environment caused by temporary equipment. This advantage is particularly evident in small urban areas or occasions with limited construction conditions.

[0003] After searching, the Chinese patent application No. 202322971699.3 discloses an assembled steel structure. The adjustment seat includes a middle block that is slidably mounted on the top of the vertical beam and a sleeve welded to the two side walls of the middle block. A support 2 is welded in the middle of the top surface of the outer end of the sleeve. A horizontal threaded sleeve is fixedly mounted on the inner side of the support 2 in a direction parallel to the axis of the sleeve. Support blocks are welded at the upper and lower sides of the middle block at the top of the vertical beam, and an axial hole 1 that is rotatably mounted at the two ends of the vertical screw rod is respectively provided in the middle of the support block. A vertical threaded sleeve that is rotatably mounted on the middle block is fixedly mounted on the middle block. One end of the horizontal beam is slidably mounted in the sleeve, and a support 1 is welded at a position on the top surface of the horizontal beam corresponding to the support 2. A axial hole 2 that is rotatably mounted on the outer end of the horizontal screw rod is provided on the support 1, and the inner end of the horizontal screw rod is threadedly mounted in the horizontal threaded sleeve. The problem that the assembled steel structure of the building is inconvenient to adjust during assembly is well solved.

[0004] The above patents still have the following shortcomings: the defect of being inconvenient to assemble. During the assembly process of existing steel structures, complex on-site welding or bolt connection operations are usually required. These operations are not only time-consuming and labor-intensive, but also require precise measurement and positioning to ensure the tightness of the installation and the stability of the connection, which increases the difficulty and cost of construction; traditional steel structures are insufficient in compressive resistance. Traditional steel structures often rely on heavy materials and huge structural systems to ensure sufficient bearing capacity, which not only increases construction costs, but also limits the flexibility of design; traditional steel structures are not effective in seismic buffering, because the rigid connection between components and the lack of sufficient flexibility result in excessive stress concentration and deformation, which are easily affected by vibration, resulting in increased stress levels of components and accelerated fatigue damage.

[0026] 3. The prefabricated building steel structure uses the first moving rod and the second moving rod to support the crossbeam and the fixed sleeve, thereby enhancing the compressive resistance of the structure. The rotating screw can push the fixed sleeve to slide on the box-shaped high-strength steel column to adjust its height, thereby achieving the effect of structural reinforcement. The triangular structure formed inside the steel structure works in coordination with other components to effectively disperse the load and enhance the overall stability of the steel structure.

[0027] 4. The prefabricated building steel structure pushes the telescopic rod through the first moving rod to make the piston reciprocate in the liquid storage tank, and converts mechanical energy into heat energy and dissipates it by using the pressure of the viscous fluid, thereby realizing the function of seismic buffering. By utilizing the movement of the viscous fluid to consume the vibration energy, the vibration amplitude of the steel structure is reduced, the stress level of the component is reduced, fatigue damage is reduced, and the service life of the steel structure is extended.

[0056] like Fig.10As shown, in one embodiment: the earthquake-resistant structure 3 includes a steel shell 301 fixed on the top of the second rotating seat 408, a second blocking end cover 309 installed inside the steel shell 301, a first blocking end cover 306 installed on the top of the steel shell 301, a telescopic rod 304 sliding inside the first blocking end cover 306, a connecting piece 305 fixed on the top of the telescopic rod 304 and connected to the first moving rod 401, a liquid storage tank 308 opened in the steel shell 301, a piston 307 fixed on the outside of the telescopic rod 304 and slidably connected to the liquid storage tank 308, a moving seat 302 threadedly connected to the outside of the steel shell 301, and a connecting piece 305 installed between the moving seat 302 and the connecting piece 306. 5, the interior of the liquid storage tank 308 is filled with viscous fluid, the telescopic rod 304 forms a telescopic structure with the first blocking end cover 306 through the viscous fluid, and the telescopic rod 304 and the second blocking end cover 309 form a sliding structure; the telescopic rod 304 is pushed by the first moving rod 401 to make the piston 307 reciprocate in the liquid storage tank 308, and at the same time, the viscous fluid is subjected to pressure to convert the mechanical energy generated by the vibration into heat energy and dissipate it, thereby reducing the vibration amplitude of the building structure, and the reset spring 303 can assist in buffering the vibration and improve the earthquake resistance effect, and the rotating moving seat 302 pushes the reset spring 303 and the connecting piece 305 to move upward, thereby extending the length of the earthquake-resistant structure 3.

[0057] Specifically, when the prefabricated building steel structure is in use: a concrete pile foundation is cast in advance in the construction area, and then the fixing frame 11 is connected and fixed to the concrete pile foundation with bolts, and the box-type high-strength steel column 1 is installed at the use position, and then the fixing sleeve 2 is sleeved on the outside of the box-type high-strength steel column 1, and the crossbeam 5 is inserted into the inside of the installation sleeve 6, and the positioning structure 7 is inserted into the inside of the box-type high-strength steel column 1 through the fixing sleeve 2 to fix the position between the box-type high-strength steel column 1, the fixing sleeve 2 and the crossbeam 5, and at the same time, the two adjacent groups of positioning structures 7 are locked and fixed by the fixing structure 9 to improve the stability of the connection between the box-type high-strength steel column 1, the fixing sleeve 2 and the crossbeam 5, and the upper and lower groups of crossbeams 5 are connected to the installation sleeve 6 by the support structure 4 to form an effective triangular structure to improve the compressive capacity of the steel structure, and at the same time, the support structure 4 can adjust the height of the upper installation sleeve 6 and the crossbeam 5, so that the positioning structure 7 can fix the position of the installation sleeve 6 and the crossbeam 5, and the anti-seismic structure 3 makes the support structure 4 have a certain flexibility during the support process, so as to buffer the vibration;

[0058] When assembling the steel structure, align the first positioning groove 8 with the second positioning groove 10, and rotate the rotary block 703 to drive the rotating shaft 705 to rotate, and then the rotating shaft 705 drives the swing arm frame 701 to rotate, so that the two ends of the swing arm frame 701 swing and drive the push arm 702 to move, so that the push arm 702 pushes the positioning pin 704 to move. Since the positioning pin 704 slides inside the guide sleeve 706, the direction and path of the positioning pin 704 are limited, so that the push arm 702 pushes the positioning pin 704 to vertically insert into the second In the positioning groove 10, the positioning pin 704 then passes through the second positioning groove 10 and enters the interior of the first positioning groove 8, fixing the position between the box-shaped high-strength steel column 1, the fixing sleeve 2 and the cross beam 5, so that the staff can position the installation of the fixing sleeve 2 and the cross beam 5, and improve the installation efficiency. The deflection range of the swing arm frame 701 is limited by the stop plate 707, but when the steel structure needs to be disassembled, the reverse rotation of the swing block 703 can make the swing block 703 retract into the interior of the cross beam 5, so as to facilitate the cross beam 5 to be taken out from the interior of the installation sleeve 6;

[0059] Insert the locating pin 704 with the connecting seat 909 into the box-shaped high-strength steel column 1 in advance, and then insert the swing arm frame 701 with the insertion rod 901 into the same group of box-shaped high-strength steel columns 1, so that the insertion rod 901 enters the inside of the connecting seat 909, and at the same time, the moving insertion rod 901 uses the inclined surface on one side to push the fixing pin 908 to completely retract into the inside of the connecting seat 909, so that the insertion rod 901 is inserted into the connecting seat 909, and then use the thrust of the telescopic spring 903 to push the push block 906 to move downward, so that the fixing pin 908 is stuck in the inside of the fixing groove 902, and the two adjacent groups of locating pins 704 are fixed, and the position of the horizontal fixing beam 5 is fixed. When disassembly is required, pull the pull ring 905 backward through the first positioning groove 8, so that the pull ring 905 passes through the pull rod 907 and the push block 906 to pull the fixing pin 908 away from the inside of the insertion rod 901, so that the insertion rod 901 is separated from the connecting seat 909 and the lock is released;

[0060] The first moving rod 401, the second moving rod 403 and the moving block 406 support the crossbeam 5 and the fixed sleeve 2 to form an effective triangular structure, thereby improving the compressive resistance of the structure. When the height of the fixed sleeve 2 needs to be adjusted, the hexagonal block 407 is rotated by using a wrench to make the hexagonal block 407 drive the screw rod 405 to rotate, and then the moving block 406 moves on the outside of the screw rod 405 through the meshing of the threads to adjust the position of the moving block 406, and then the moving block 406 pushes the second moving rod through the second rotating seat 408. 403 moves with the first moving rod 401, and makes the fixing sleeve 2 slide on the outside of the box-shaped high-strength steel column 1, so as to adjust the height of the fixing sleeve 2. The second rotating seat 408 and the first rotating seat 402 are used to rotate the second moving rod 403 and the first moving rod 401 during the height adjustment process, and adjust the placement angle of the second moving rod 403 and the first moving rod 401. The moving block 406 slides on the top of the crossbeam 5 to guide the movement of the moving block 406, so that the moving block 406 can only move in a straight line.

[0061] The anti-seismic structure 3 is arranged between the first moving rod 401 and the second moving rod 403 to transmit the force between the first moving rod 401 and the second moving rod 403. When vibration occurs, the steel structure is slightly deformed, and the first moving rod 401 pushes the connecting piece 305 and the telescopic rod 304 to move. At the same time, the telescopic rod 304 drives the piston 307 to slide inside the liquid storage tank 308, so that the piston 307 reciprocates in the liquid storage tank 308. At the same time, the viscous fluid is pressurized between the piston 307 and the steel shell 301. When the fluid flows in the gap between the two ends, severe friction and throttling damping will be generated, and the mechanical energy generated by the vibration will be converted into heat energy and dissipated, thereby reducing the vibration amplitude of the building structure. The second blocking end cap 309 limits the position of the telescopic rod 304 and guides the movement of the telescopic rod 304. The first blocking end cap 306 prevents the leakage of viscous fluid. The reset spring 303 can assist in buffering the vibration and improve the anti-seismic effect. The rotating movable seat 302 pushes the reset spring 303 and the connecting piece 305 to move upward, thereby extending the length of the anti-seismic structure 3.
