Description

Technical Field

[0001] The present invention belongs to the technical field of building components, and particularly relates to a connecting component for steel structures of beam-column in prefabricated buildings. Background Art

[0002] A steel structure connecting component refers to a carrier for mutual connection between steel structure components or parts. Most of prefabricated steel structure buildings, prefabricated steel structure bridges, etc. are assembled and connected on-site by steel structure connecting components, and have higher working efficiency compared with traditional cast-in-place concrete structures.

[0003] When the existing steel structure beam-columns are lapped and positioned, the installation method of angle steel and bolts is generally adopted to position and reinforce the connection of beam-columns. However, for the positioning of steel structure beam-columns by this method, the gravity is borne and supported by the angle steel during use. At the connection of beam-columns, multiple bolt positionings and reinforcements are required, making the connection positioning operation inconvenient. Moreover, during high-altitude suspension operations, the processing time is long, and it is not convenient for the later maintenance and replacement of the connecting component, affecting the later maintenance;

[0004] Moreover, when the existing steel structure beam-columns are lapped, usually openings are provided in the connecting piece so that the steel structure beam-columns can be directly inserted. However, the existing steel structure beam-columns are usually used repeatedly, and dirt will be generated inside over a long time, causing blockage, which will hinder the normal structural connection, affect the force transmission and bearing capacity of the connecting piece, thereby reducing the overall strength of the steel structure connection and also reducing the practicability.

[0005] Therefore, we propose a connecting component for steel structures of beam-column in prefabricated buildings to solve the above problems. Summary of the Invention

[0009] In the above-mentioned prefabricated building beam-column steel structure connecting member, the liquid discharging mechanism includes multiple support rods fixedly connected to the outer wall of the guiding plate, multiple liquid storage tubes corresponding to each other in position are installed on the inner walls of the first connecting plate and the second connecting plate, piston plates matching the liquid storage tubes are movably connected to the inner walls of the multiple liquid storage tubes, multiple piston plates are fixedly connected to the support rods, and liquid discharging plates are communicated with one ends of the multiple liquid storage tubes.

[0010] In the above-mentioned prefabricated building beam-column steel structure connecting member, the auxiliary mechanism includes a second threaded slider threadedly sleeved on the outer wall of the threaded rod, two fixing blocks corresponding to each other in position are fixedly connected to the outer wall of the second threaded slider, auxiliary plates are fixedly connected to the outer walls of the two fixing blocks, two third limiting chutes corresponding to each other in position are opened on the outer walls of the two second connecting plates, and second limiting sliders matching the third limiting chutes are fixedly connected to the outer walls of the two auxiliary plates.

[0011] In the above-mentioned prefabricated building beam-column steel structure connecting component, the outer walls of the two load-bearing plates are each provided with two through holes corresponding to each other, and a first support plate is fixedly connected in the corresponding through holes, and a compensation spring that can be pressed and deformed is fixedly connected to the outer wall of the first support plate, and a second support plate is fixedly connected to the outer wall of the compensation spring, and the second support plate is slidably connected to the inner wall of the through hole.

[0015] Compared with the existing technology, the advantages of an assembled building beam-column steel structure connection component are:

[0016] 1. The support plate, rotating block, rotating rod, bidirectional screw, first U-shaped shell, second connecting rod, first connecting plate, first threaded slider and load-bearing plate cooperate with each other. When the staff rotates the bidirectional screw through the rotating block and the rotating rod, the two first threaded sliders move toward the center of the bidirectional screw, so that multiple first U-shaped shells move. Since the second connecting rod and the first connecting rod are hinged with the first connecting plate, the two load-bearing plates can move upward until they contact the first steel structure body. The use of the support plate for preliminary fixation can provide temporary support to prevent the first steel structure body from becoming unstable or tilted during the connection process, thereby ensuring the safety of the workers. The use of the load-bearing plate for fixation can simplify the construction process and reduce the need for complex connectors. The load-bearing plate is easier to install and disassemble, saving construction time and labor costs.

[0017] 2. Through the mutual cooperation of the liquid storage pipe, piston plate, guide plate, support rod and the second steel structure body, when the second steel structure body moves forward, the piston plate will extrude the hydraulic oil in the liquid storage pipe. The hydraulic oil can form a lubricating film on the contact surface of the second steel structure body, reducing friction and wear, which helps to extend the service life of the connecting piece and improve its performance. The hydraulic oil can also form a protective film on the surface to prevent the corrosion and oxidation of the steel structure connecting piece, extending its life and improving its durability.

[0018] 3. Through the mutual cooperation of the threaded rod, thread groove, auxiliary plate, second threaded slider and fixed plate, when the staff transports the second steel structure body to the threaded rod, the threaded rod can rotate in the thread groove. During the process of feeding the second steel structure body, the auxiliary plate, second threaded slider and fixed plate extend to assist the second steel structure body to enter, ensuring that the threaded rod and the thread groove remain horizontal during the connection process and avoiding the deviation or dislocation of the second steel structure body.

Specific implementation mode

[0027] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments.

[0028] As Figures 1-7 shown, an assembled building beam-column steel structure connecting member includes a fixing plate 1. The outer wall of the fixing plate 1 is in contact connection with two first steel structure bodies 2 corresponding to each other in position. Two support plates 3 corresponding to each other in position are installed on the inner walls of the two first steel structure bodies 2. The outer wall of one of the support plates 3 is fixedly connected to the fixing plate 1. The outer walls of the two support plates 3 are fixedly connected with a rectangular shell 4. A bidirectional screw 5 is rotatably connected to the inner wall of the rectangular shell 4. Two first threaded sliders 6 corresponding to each other in position are threadedly sleeved on the rod wall of the bidirectional screw 5. First limiting chutes 7 matching the first threaded sliders 6 are opened at both the upper and lower ends of the rectangular shell 4. One end of the bidirectional screw 5 is fixedly connected with a rotating rod 8, and the other end is fixedly connected with a threaded rod 9. Two first U-shaped frames 10 corresponding to each other in position are fixedly connected to the outer walls of the two first threaded sliders 6. First connecting rods 11 corresponding to each other in position are installed on the inner walls of multiple first U-shaped frames 10. Load-bearing plates 12 are in contact connection with the outer walls of the first steel structure bodies 2. Two second U-shaped frames 13 corresponding to each other in position are fixedly connected to the outer walls of the two load-bearing plates 12. Second connecting rods 14 corresponding to each other in position are installed on the inner walls of multiple second U-shaped frames 13. A first connecting plate 15 is hinged between the second connecting rod 14 and the first connecting rod 11. An auxiliary mechanism 16 is installed on the rod wall of the threaded rod 9.

[0029] Two second connecting plates 17 corresponding to each other in position are fixedly connected to the outer wall of the first connecting plate 15. The outer walls of the two second connecting plates 17 are both in contact connection with a second steel structure body 18. Second limiting sliding grooves 19 are formed in the outer walls of the two second connecting plates 17. First limiting sliders 20 matching with the second limiting sliding grooves 19 are slidably connected to the inner walls of the two second limiting sliding grooves 19. The outer walls of the two first limiting sliders 20 are fixedly connected to the same guiding plate 21. A liquid outlet mechanism 22 is installed on the outer wall of the guiding plate 21.

[0030] The liquid outlet mechanism 22 includes a plurality of support rods 221 fixedly connected to the outer wall of the guiding plate 21. A plurality of liquid storage pipes 222 corresponding to each other in position are installed on the inner walls of the first connecting plate 15 and the second connecting plate 17. Piston plates 223 matching with the liquid storage pipes 222 are movably connected to the inner walls of the plurality of liquid storage pipes 222. The plurality of piston plates 223 are all fixedly connected to the support rods 221. One ends of the plurality of liquid storage pipes 222 are all communicated with a liquid outlet plate 224. The hydraulic oil can form a lubricating film on the contact surface of the second steel structure body 18 to reduce friction and wear, which helps to extend the service life of the connecting piece and improve its performance. The hydraulic oil can also form a protective film on the surface to prevent the corrosion and oxidation of the steel structure connecting piece, extend its life and improve its durability.

[0031] The auxiliary mechanism 16 includes a second threaded slider 161 threadedly sleeved on the outer wall of the threaded rod 9. Two fixing blocks 162 corresponding to each other in position are fixedly connected to the outer wall of the second threaded slider 161. Auxiliary plates 163 are fixedly connected to the outer walls of the two fixing blocks 162. Two third limiting sliding grooves 164 corresponding to each other in position are formed in the outer walls of the two second connecting plates 17. Second limiting sliders 165 matching with the third limiting sliding grooves 164 are fixedly connected to the outer walls of the two auxiliary plates 163. During the process of feeding the second steel structure body 18, the auxiliary plates 163 extend under the action of the second threaded slider 161 and the fixing blocks 162 to assist the second steel structure body 18 to enter, which can ensure that the threaded rod 9 and the threaded groove 35 remain horizontal during the connection process and avoid the second steel structure body 18 from shifting or being misaligned.

[0032] Two through holes 23 corresponding to each other in position are formed in the outer walls of the two load-bearing plates 12. First support plates 24 are fixedly connected to the corresponding through holes 23. A compensating spring 25 that can be pressed and deformed is fixedly connected to the outer wall of the first support plate 24. A second support plate 26 is fixedly connected to the outer wall of the compensating spring 25. The second support plate 26 is slidably connected to the inner wall of the through hole 23.

[0033] A rectangular frame 27 is installed at the lower end of multiple through holes 23. Multiple rectangular frames 27 are fixedly connected to the load-bearing plate 12. A water-stop block 28 is fixedly connected to the inner wall of the rectangular frame 27. A blocking soft block 29 is installed at the upper end of the water-stop block 28. The blocking soft block 29 is located below the through hole 23 and is adapted to the through hole 23. The water-stop block 28 can effectively prevent water leakage and provide protection and safety. It simplifies the maintenance work and improves the durability and reliability of the structure.

[0034] One end outer wall of the rotating rod 8 is fixedly connected with a rotating block 30. Multiple anti-slip grooves 31 corresponding to each other in position are arranged on the outer surface of the rotating block 30. A bolt 32 is installed on the outer wall of the fixing plate 1. The fixing plate 1 is fixedly connected to the outer wall of the first steel structure body 2 through the bolt 32.

[0035] Multiple liquid outlet holes 33 corresponding to each other in position are arranged on the outer walls of multiple liquid outlet plates 224. Multiple balls 34 corresponding to each other in position are installed on the outer walls of two second connecting plates 17. A thread groove 35 matching the threaded rod 9 is arranged on the outer wall of the second steel structure body 18.

[0036] Now, the operating principle of the present invention is described as follows:

[0037] First, the staff places the connecting member on the outer walls of two first steel structure bodies 2, so that the two support plates 3 initially fix the first steel structure. Then, the staff rotates the bidirectional screw rod 5 through the rotating block 30 and the rotating rod 8, so that the two first threaded sliders 6 move towards the central part of the bidirectional screw rod 5, and multiple first U-shaped shells move. Since the second connecting rod 14 and the first connecting rod 11 are hinged to the first connecting plate 15, the two load-bearing plates 12 move upward until they abut against the first steel structure body 2. Using the support plate 3 for preliminary fixation can provide temporary support, prevent the first steel structure body 2 from being unstable or tilted during the connection process, and ensure the safety of the workers. Using the load-bearing plate 12 for fixation can simplify the construction process, reduce the need for complex connecting parts, and the load-bearing plate 12 is easier to install and disassemble, saving construction time and labor costs;

[0038] Since the threaded rod 9 is fixedly connected to the bidirectional screw rod 5, when the first steel structure body 2 is initially fixed, at this time, the staff places the second steel structure body 18 in the housing formed by the second connecting plate 17 and the first connecting plate 15. Since the outer wall of the second steel structure body 18 is provided with a thread groove 35, the staff transports the second steel structure body 18 to the position of the threaded rod 9, so that the threaded rod 9 can rotate in the thread groove 35. During the process of feeding the second steel structure body 18, the auxiliary plate 163, the second threaded slider 161 and the fixing plate 1 extend, assisting the second steel structure body 18 to enter, which can ensure that the threaded rod 9 and the thread groove 35 remain horizontal during the connection process, and avoid the second steel structure body 18 from shifting or being misaligned;

[0039] After the threaded rod 9 is connected to the threaded groove 35, the second steel structure body 18 will abut against the guide plate 21. Since the liquid storage pipes 222 are installed on the inner walls of the first connecting plate 15 and the second connecting plate 17, and the piston plates 223 are fixedly connected to the support rods 221 connected to the guide plate 21, when the second steel structure body 18 continues to move forward, the piston plates 223 will extrude the hydraulic oil in the liquid storage pipes 222. The hydraulic oil can form a lubricating film on the contact surface of the second steel structure body 18, reducing friction and wear, which helps to extend the service life of the connecting piece and improve its performance. The hydraulic oil can also form a protective film on the surface to prevent the corrosion and oxidation of the steel structure connecting piece, extending its life and improving its durability.

[0040] The above are only the preferred embodiments of the present invention, and are not intended to limit the present invention.
