Description

Technical Field

[0001] The utility model relates to the technical field of building construction, and more particularly to a fireproof steel structure of a building. Background Art

[0002] During construction, in order to ensure project progress and efficiency, it is necessary to quickly install and dismantle steel structures in large-scale construction projects. The currently widely used welding process has high connection strength, but it requires professional welding equipment and technicians. The welding process is time-consuming and easily affected by weather conditions at the construction site. The welding fume generated can also harm the health of construction workers. The welded components are not easy to disassemble and reuse later, which greatly increases the project cost.

[0003] In the construction of high-rise buildings, in order to ensure construction safety and improve construction efficiency, a convenient and reliable connection method needs to be adopted. Although traditional bolt connections can be repeatedly disassembled and assembled, in high-altitude operations, since multiple sets of bolts need to be installed at the same time, the operation process is cumbersome and it is easy to cause safety hazards such as bolt loosening or falling off. In addition, in severe weather conditions, bolts are prone to rust, which affects the connection strength, increases construction difficulty and maintenance costs, and cannot meet the fast, efficient and safe construction needs of modern building construction.

[0015] (3) Beneficial effects

[0016] Compared with the existing technology, the utility model provides a fireproof steel structure for buildings, which has the following beneficial effects:

[0017] 1. The fixing mechanism realizes quick connection by setting a bottom plate at the top of the pillar and a top plate at the bottom of the top beam, and setting a bolt between the two. The cooperation between the positioning rod and the positioning hole ensures the accuracy of the installation position of the bolt. The setting of multiple sets of reinforcing ribs enhances the connection strength between the bottom plate and the pillar. The clamping block maintains elastic connection with the fixing sleeve under the action of the tension spring. The clamping block is precisely controlled by the cooperation of the ejector rod and the push block, so that it can be accurately inserted into the slot on the outer wall of the bolt, forming a connection system that is easy to install, accurately positioned and has a stable structure.

[0018] 2. The locking mechanism is achieved by arranging a sliding sleeve on the fixed sleeve and installing a locking sleeve on the inner side thereof. Multiple sets of locking blocks are used to form a reliable locking fit with the locking grooves on the bottom surface of the clamping block. At the same time, the setting of the limit slide ensures that the moving trajectory of the sliding sleeve is accurate. Combined with the overall structure of the fixed sleeve, a double locking mechanism is formed, making the connection more firm and reliable, effectively preventing the connection from loosening due to external force, and improving the safety of the entire structure.

[0019] 3. The limiting mechanism utilizes the ingenious coordination of the through hole and the limiting groove on the limiting sleeve, combined with the support rod and the limiting block installed on the rotating sleeve, to achieve precise control of the position of the sliding sleeve under the action of the push spring. The limiting block can be flexibly switched between the through hole and the limiting groove by the rotation of the rotating sleeve, which can be firmly locked and quickly unlocked. This design not only improves the reliability of the locking mechanism, but also greatly improves the convenience of disassembly and assembly, forming a limiting system that is easy to operate and reliable in function.

The locking mechanism includes a sliding sleeve 11, a locking sleeve 12, a locking block 13, a locking groove 14 and a limiting mechanism. The sliding sleeve 11 is slidably mounted on the fixed sleeve 6, and the locking sleeve 12 is mounted on the inner side of the sliding sleeve 11. The locking block 13 is provided with multiple groups installed on the top of the locking sleeve 12, and the lock groove 14 is provided on the bottom surface of the multiple groups of clamping blocks 7.

[0030] Reinforcing ribs 21 are installed between the base plate 3 and the pillar 1 . There are multiple groups of reinforcing ribs 21 . The reinforcing ribs 21 provide additional support and connection strength.

[0031] A positioning rod 22 is installed on the inner top surface of the fixing sleeve 6, and a positioning hole 23 is opened at the top of the plug 5. There are multiple groups of positioning rods 22 and positioning holes 23, which are adapted to each other. The inner top surface of the fixing sleeve 6 and the top of the plug 5 are provided with positioning structures that cooperate with each other. Multiple groups of positioning rods 22 and positioning holes 23 form a precise positioning system.

[0032] Tension springs 24 are provided between the multiple groups of clamping blocks 7 and the fixing sleeves 6. The clamping blocks 7 and the fixing sleeves 6 are connected by the tension springs 24 to provide elastic restoring force.

[0033] The outer wall of the fixed sleeve 6 is provided with a limiting slide bar 25 . The limiting slide bar 25 is provided in multiple groups and is slidably connected to the sliding sleeve 11 to form a guiding sliding structure with the sliding sleeve 11 .

[0034] In this embodiment, when the pillar 1 and the top beam 2 need to be spliced, the plug 5 is inserted through the bottom plate 3 and the top plate 4, and then the positioning hole 23 set at the top of the plug 5 is aligned with the positioning rod 22 set in the fixing sleeve 6 and inserted, and then the multiple push springs 26 are pressed to push the top rod 9 and simultaneously stretch the multiple tension springs 24, pushing the multiple clamping blocks 7 to be inserted into the clamping grooves 8 set on the outer wall of the plug 5, and then the sliding sleeve 11 slides along the multiple limit slides 25, driving the locking sleeve 12 to slide, and the locking sleeve 12 pushes the multiple lock blocks 13 to be clamped in the multiple sets of The locking groove 14 provided on the bottom surface of the clamping block 7 is then used to limit the position of the sliding sleeve 11 by the limiting mechanism to complete the installation and fixation. When disassembly is required, the restriction of the sliding sleeve 11 by the limiting mechanism is released, and then the sliding sleeve 11 is slid downward to drive the locking sleeve 12 and the multiple sets of locking blocks 13 to disengage from the locking groove 14, thereby releasing the lock of the multiple sets of clamping blocks 7. Subsequently, the multiple sets of clamping blocks 7 are pulled outward by the tension spring 24 to slide out of the clamping groove 8, and then the clamping of the bolt 5 can be released, and then the bolt 5 can be separated from the fixing sleeve 6 to release the fixation of the top plate 4 and the bottom plate 3.

[0035] See also Figure 5 , as an implementation method of the limiting mechanism: the limiting mechanism includes a limiting sleeve 15, a through hole 16, a limiting groove 17, a rotating sleeve 18, a support rod 19 and a limiting block 20, the limiting sleeve 15 is arranged on the outer wall of the sliding sleeve 11, the through holes 16 are provided with multiple groups distributed on the limiting sleeve 15, the limiting grooves 17 are provided on the outside of the multiple groups of through holes 16, the rotating sleeve 18 is rotatably installed on the outer wall of the fixed sleeve 6, the support rod 19 is provided with multiple groups installed on the rotating sleeve 18, and the limiting block 20 is installed on the top of the multiple groups of support rods 19.

[0036] The rotating sleeve 18 is provided with a push spring 26 , and the push spring 26 is provided in multiple groups to provide continuous elastic thrust.

[0037] The diameters of the multiple groups of through holes 16 are all larger than the limit blocks 20 , and the diameters of the multiple groups of limit grooves 17 are all smaller than the limit blocks 20 . A selective passing mechanism is formed by designing different apertures. The limit blocks 20 can pass through the through holes 16 but cannot pass through the limit grooves 17 .

[0038] More specifically, when the locking mechanism locks the clamping block 7, the limit block 20 at the top of the multiple groups of support rods 19 abuts against the bottom surface of the limit sleeve 15, and the sliding sleeve 11 is locked at this time. When the lock needs to be released, the rotating sleeve 18 is rotated to drive the multiple groups of support rods 19 and the limit blocks 20 to rotate. When the multiple groups of limit blocks 20 move to the position of the through holes 16, the sliding sleeve 11 is slid downward so that the multiple groups of limit blocks 20 pass through the through holes 16 and squeeze the multiple groups of push springs 26. Then, the rotating sleeve 18 is continued to be rotated to drive the support rods 19 to move into the limit groove 17. At this time, the limit sleeve 15 is pushed by the multiple groups of push springs 26 so that its top surface abuts against the bottom surface of the multiple groups of limit blocks 20, and the limit sleeve 15 can be fixed. At this time, the locking mechanism continues to be in the unlocked state.

[0039] In summary, when the overall equipment is in use or running: when it is necessary to splice the pillar 1 and the top beam 2, the plug 5 is inserted through the bottom plate 3 and the top plate 4, and then the positioning hole 23 set at the top of the plug 5 is aligned with the positioning rod 22 set in the fixing sleeve 6 and plugged, and then the multiple push blocks 10 are pressed to push the top rod 9 and simultaneously stretch the multiple tension springs 24, and push the multiple clamping blocks 7 to be inserted into the clamping groove 8 set on the outer wall of the plug 5, and then the sliding sleeve 11 slides along the multiple limit slides 25, driving the locking sleeve 12 to slide, and the locking sleeve 12 pushes the multiple lock blocks 13 to lock. The locking sleeve 12 and the locking blocks 13 are connected to each other in the locking groove 14 provided on the bottom surface of the multiple-group clamping block 7, and then the position of the sliding sleeve 11 is limited by the limiting mechanism to complete the installation and fixation. When disassembly is required, the restriction of the sliding sleeve 11 by the limiting mechanism is released, and then the sliding sleeve 11 is slid downward to drive the locking sleeve 12 and the multiple-group locking blocks 13 to disengage from the locking groove 14, thereby releasing the lock of the multiple-group clamping blocks 7. Subsequently, the multiple-group clamping blocks 7 are pulled outward by the tension spring 24 to slide out of the clamping groove 8, and then the clamping of the plug 5 can be released, and then the plug 5 can be separated from the fixing sleeve 6 to release the fixation of the top plate 4 and the bottom plate 3.

[0040] When the locking mechanism locks the clamping block 7, the limit block 20 at the top of the multiple groups of support rods 19 abuts against the bottom surface of the limit sleeve 15, and the sliding sleeve 11 is locked at this time. When the lock needs to be released, the rotating sleeve 18 is rotated to drive the multiple groups of support rods 19 and the limit blocks 20 to rotate. When the multiple groups of limit blocks 20 move to the position of the through holes 16, the sliding sleeve 11 is slid downward so that the multiple groups of limit blocks 20 pass through the through holes 16 and squeeze the multiple groups of push springs 26. Then, the rotating sleeve 18 is continued to be rotated to drive the support rods 19 to move into the limit groove 17. At this time, the limit sleeve 15 is pushed by the multiple groups of push springs 26 to make its top surface abut against the bottom surface of the multiple groups of limit blocks 20, so that the limit sleeve 15 can be fixed. At this time, the locking mechanism continues to be in the unlocked state.

[0041] In all the schemes mentioned above, the connection between the two components can be selected according to actual conditions by welding, bolt and nut connection, bolt or screw connection or other well-known connection methods, which will not be listed here one by one. In the above, all fixed connections are preferably welded. Although the embodiments of the present invention have been shown and described, it can be understood by ordinary technicians in this field that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention.
