Description

Technical Field

[0001] This invention relates to the field of steel structure corridor technology, specifically to a steel structure corridor support connection device and its connection method. Background Technology

[0002] Connecting corridors, originally a form of ancient Chinese architecture, are now defined as a complex high-rise building structural system. They generally refer to connecting two or more high-rise buildings via an elevated connecting structure, often made of steel, to meet architectural aesthetics and functional requirements. Steel-structured connecting corridors are used for several reasons. Firstly, they facilitate communication between towers, providing good lighting and expansive views, making them suitable as sightseeing walkways or casual cafes. Secondly, they enhance the building's appearance and create a more harmonious architectural atmosphere. Additionally, some serve as fire escape routes.

[0003] Currently, when existing steel structure corridors are connected to concrete walls, in order to ensure the stability of the building structure, a large number of bolts and screw holes are often used to connect the ends of the steel structure corridors to the concrete beams. The construction operation is not only cumbersome and complicated, time-consuming and labor-intensive, but also difficult to effectively fix the connecting parts tightly, which makes it easy for movement and displacement to occur, resulting in loose connections and poor stability. Summary of the Invention

[0004] The purpose of this invention is to provide a steel structure corridor support connection device and its connection method. By setting a fixed plate and a positioning plate between the support base and the beam base, and with the cooperation of a first moving mechanism, a locking block, and a locking slot, the positioning plate can be locked inside the fixed plate. Furthermore, by setting a reinforcing component between the fixed plate and the positioning plate, the fixed plate and the positioning plate can be further locked, thereby greatly strengthening the connection strength between the positioning plate and the fixed plate. By setting structures such as inserts, slots, and a second moving mechanism on the fixed plate and the locking block, the inserts can extend out of the locking block and be inserted into the slot of the positioning plate, thereby further limiting and fixing, and thus greatly improving the tightness of the positioning plate and the fixed plate. This invention is not only simple and convenient to operate and has high construction efficiency, but also effectively ensures the stability and reliability of the steel structure corridor support connection under multiple fixed connections, thereby solving the above-mentioned shortcomings in the technology.

[0005] To achieve the above objectives, the present invention provides the following technical solution: a steel structure connecting corridor support connection device and its connection method, comprising:

[0006] A concrete main body, with a beam seat fixed on one side of the concrete main body;

[0007] A steel structure connecting corridor, wherein a support base is fixed at the bottom end of the steel structure connecting corridor;

[0008] A connecting mechanism is provided between the beam seat and the support seat. The connecting mechanism includes fixed plates symmetrically fixed at both ends of the top of the beam seat. Positioning plates that can move towards or away from each other are symmetrically arranged at both ends of the bottom of the support seat. A slot is provided on the outer side of each of the two positioning plates. A matching card plate is fixed on the inner side of the fixed plate. A reinforcing component is provided between the fixed plate and the positioning plate. A first moving mechanism is provided inside the support seat. The first moving mechanism is used to drive the two positioning plates to move.

[0009] The cavity is formed inside the card plate, and movable inserts are symmetrically arranged at both ends of the cavity. Both ends of the card plate have channels facing the inserts, and both ends of the positioning plate have slots facing the channels. The card plate is provided with a second moving mechanism, which is used to drive the two inserts to move.

[0010] Preferably, the first moving mechanism is formed in the groove in the middle of the bottom of the support base. A bidirectional screw is rotatably connected inside the groove via a bearing. Both ends of the bidirectional screw are connected to a fixing block by threaded connection. One end of the bidirectional screw extends outside the support base and is fixed with a first fixing handle. The bottom ends of the two fixing blocks are respectively fixedly connected to two positioning plates.

[0011] Preferably, the second moving mechanism includes a connecting shaft rotatably connected to the cavity through a bearing. One end of the connecting shaft and located between the two inserts is fixed with a gear, and the other end of the connecting shaft passes through a fixing plate and is connected to a second fixing handle. The inner sides of the two inserts are fixed with toothed plates, and both toothed plates mesh with the gear.

[0012] Preferably, a limiting block is fixed to one end of the insertion post relative to the toothed plate, and a limiting groove matching the limiting block is provided on the inner wall of the cavity.

[0013] Preferably, the reinforcing component includes positioning posts fixed to the four ends of the inner side of the positioning plate, and the four ends of the side wall of the fixing plate are provided with positioning holes that match the positioning posts.

[0014] Preferably, one end of the positioning post passes through the positioning hole and is provided with a threaded section, and the outer wall of the threaded section is provided with a threaded cap.

[0015] Preferably, both ends of the cavity are provided with sliding cavities facing the insertion post. A connecting block is slidably connected inside the sliding cavity. One end of the connecting block extends outside the sliding cavity and is fixedly connected to the insertion post. A first spring is fixed inside one end of the sliding cavity. One end of the first spring is fixedly connected to the connecting block. A guide rod is connected through the first spring and the connecting block. Both ends of the guide rod are fixedly connected to the inner wall of the sliding cavity.

[0016] Preferably, a second spring is sleeved on the outside of the bidirectional screw, and the two ends of the second spring are respectively fixedly connected to two fixing blocks.

[0017] Preferably, one end of the steel structure corridor is provided with multiple rubber columns facing the concrete main body.

[0018] A connection method for a steel structure connecting corridor support connection device includes the following specific steps:

[0019] S1. By placing the support base between the tops of the two fixed plates on the beam seat, the two positioning plates are in a retracted and close-fitting state. Then, the first fixing handle is turned to drive the bidirectional screw to rotate. Under the action of the two reverse threads, the bidirectional screw can drive the two fixing blocks to move in opposite directions. Then, the fixing blocks drive the positioning plates to move, so that the two positioning plates move away from each other and abut against the side fixing plates. Then, the locking plate on the inner side of the fixing plate is fitted into the locking groove on the inner side of the positioning plate, so that the positioning plate and the fixing plate can be locked together to achieve quick fixation between the support base and the beam seat.

[0020] S2. When the two fixed blocks approach each other, the second spring can be compressed and deformed. Conversely, when the two fixed blocks move away from each other, the second spring rebounds and is always compressed by the two fixed blocks, thus having a rebound force. Under the elastic action of the second spring, the two fixed blocks can be effectively prevented from approaching and closing. After the positioning plate and the fixed plate are locked, the positioning plate can be effectively prevented from moving or displacing.

[0021] S3. At the same time, when the positioning plate is close to the fixed plate, the positioning pins at the four ends of the positioning plate can be inserted into the positioning holes at the four ends of the fixed plate, and the threaded section on the positioning pin passes through the positioning hole. Then, the threaded cap is tightened on the threaded section so that the threaded cap is pressed against the outer wall of the fixed plate, thereby greatly strengthening the connection strength between the positioning plate and the fixed plate.

[0022] S4. After the positioning plate and the fixing plate are fixedly connected, the second fixing handle can be turned to drive the connecting shaft to rotate. Then the connecting shaft drives the gear to rotate, which in turn drives the upper and lower tooth plates to move. Then the tooth plates drive the insertion column to move, so that the upper and lower insertion columns can move towards each other. After that, the insertion column passes through the channel and is inserted into the slot on the positioning plate for further limiting and fixing. This greatly improves the tightness between the support base and the beam base. It is not only simple and convenient to operate and has high construction efficiency, but also can effectively ensure the stability and reliability of the steel structure corridor support connection under multiple fixed connections.

[0023] S5. By rotating the second fixing handle in the opposite direction, the two inserts can be brought closer together and retracted into the cavity. Then, the inserts can drive the connecting block to slide along the guide rod, causing the connecting block to squeeze the first spring. At this time, the first spring contracts and deforms. When the inserts extend out of the cavity again, under the elastic compensation of the first spring, the insertions can be further prevented from moving, thereby greatly improving the stability of the structure during connection.

[0024] The technical effects and advantages provided by the present invention in the above technical solution are as follows:

[0025] By setting a fixed plate and a positioning plate between the support base and the beam base, and with the cooperation of the first moving mechanism, the locking block and the locking groove, the two positioning plates can be inserted between the two fixed plates, and the positioning plates can be moved and locked inside the fixed plates, thereby achieving rapid fixing between the support base and the beam base.

[0026] Furthermore, by setting a reinforcing component between the fixed plate and the positioning plate, the fixed plate and the positioning plate can be further locked together, thereby greatly strengthening the connection strength between the positioning plate and the fixed plate.

[0027] By setting up structures such as inserts, slots, and a second moving mechanism on the fixed plate and the locking block, after the fixed plate and the positioning plate are fixedly connected, the inserts can extend out of the locking block and be inserted into the slots of the positioning plate, thereby further limiting and fixing, which greatly improves the tightness between the support and the beam. It is not only simple and convenient to operate and has high construction efficiency, but also can effectively ensure the stability and reliability of the steel structure corridor support connection under multiple fixed connections.

[0028] By setting a second spring in the groove, the second spring is always compressed and deformed by the two fixed blocks. Under the action of this structure, when the positioning plate and the fixed plate are locked, the two fixed blocks can be effectively prevented from approaching and closing, thereby effectively preventing the positioning plate from moving. Furthermore, by setting a sliding cavity, a first spring and a connecting block in the card block, the insertion post can be further prevented from moving, thus greatly improving the stability of the structure during connection.

[0043] To enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0044] This invention provides, for example Figures 1-11 The steel structure connecting corridor support connection device shown includes:

[0045] Concrete main body 1, with a beam seat 5 fixed on one side of the concrete main body 1;

[0046] The steel structure connecting corridor 31 has a support base 3 fixed at its bottom end;

[0047] One end of the steel structure corridor 31 is provided with multiple rubber columns 32 facing the concrete main body 1. The rubber columns 32 can be used to buffer the vibration and impact between the concrete main body 1 and the steel structure corridor 31.

[0048] The connecting mechanism is located between the beam seat 5 and the support seat 3. The connecting mechanism includes a fixing plate 6 symmetrically fixed at both ends of the top of the beam seat 5. The bottom ends of the support seat 3 are symmetrically provided with positioning plates 4 that can move towards or away from each other. The outer sides of the two positioning plates 4 are provided with slots 8. The inner side of the fixing plate 6 is fixed with a card plate 7 that matches the slot 8. A reinforcing component is provided between the fixing plate 6 and the positioning plate 4. The support seat 3 is provided with a first moving mechanism, which is used to drive the two positioning plates 4 to move.

[0049] The first moving mechanism is located in the groove 27 at the bottom center of the support base 3. A bidirectional screw 28 is rotatably connected inside the groove 27 via a bearing. Both ends of the bidirectional screw 28 are connected to a fixing block 29 by threaded engagement. One end of the bidirectional screw 28 extends outside the support base 3 and is fixed with a first fixing handle 2. The bottom ends of the two fixing blocks 29 are respectively fixedly connected to two positioning plates 4.

[0050] In use, the support base 3 is placed between the tops of the two fixing plates 6 on the beam seat 5. At this time, the two positioning plates 4 are in a retracted and close-fitting state. Then, the first fixing handle 2 is turned, which drives the bidirectional screw 28 to rotate. Under the action of the two reverse threads, the bidirectional screw 28 can drive the two fixing blocks 29 to move in opposite directions. Then, the fixing blocks 29 drive the positioning plates 4 to move, so that the two positioning plates 4 move away from each other and abut against the side fixing plates 6. Then, the locking plate 7 on the inner side of the fixing plate 6 is fitted into the locking groove 8 on the inner side of the positioning plate 4, so that the positioning plate 4 and the fixing plate 6 can be locked together to achieve quick fixation between the support base 3 and the beam seat 5.

[0051] The reinforcement component includes positioning posts 9 fixed to the four ends of the inner side of the positioning plate 4, and positioning holes 10 matching the positioning posts 9 are provided at the four ends of the side wall of the fixing plate 6.

[0052] One end of the positioning pin 9 passes through the positioning hole 10 and is provided with a threaded section 11. A threaded cap 12 is provided on the outer wall of the threaded section 11.

[0053] When the positioning plate 4 is close to the fixing plate 6, the positioning pins 9 at the four ends of the positioning plate 4 can be inserted into the positioning holes 10 at the four ends of the fixing plate 6, and the threaded section 11 on the positioning pin 9 passes through the positioning hole 10. Then, the threaded cap 12 is screwed on the threaded section 11, so that the threaded cap 12 abuts against the outer wall of the fixing plate 6, thereby greatly strengthening the connection strength between the positioning plate 4 and the fixing plate 6.

[0054] A second spring 30 is sleeved on the outside of the bidirectional screw 28, and the two ends of the second spring 30 are respectively fixedly connected to two fixing blocks 29.

[0055] When the two fixed blocks 29 approach each other, the second spring 30 is compressed and deformed. Conversely, when the two fixed blocks 29 move away from each other, the second spring 30 rebounds and is always compressed by the two fixed blocks 29, thus having a rebound force. Under the elastic action of the second spring 30, the two fixed blocks 29 can be effectively prevented from approaching and closing. Therefore, after the positioning plate 4 and the fixed plate 6 are locked, the positioning plate 4 can be effectively prevented from moving or displacing.

[0056] The cavity 13 is formed inside the card plate 7, and movable inserts 17 are symmetrically arranged at both ends of the cavity 13. Both ends of the card plate 7 are provided with channels 19 facing the inserts 17. Both ends of the positioning plate 4 are provided with slots 20 facing the channels 19. The card plate 7 is provided with a second moving mechanism, which is used to drive the two inserts 17 to move.

[0057] The second moving mechanism includes a connecting shaft 14 rotatably connected to the cavity 13 via a bearing. One end of the connecting shaft 14 and located between two inserts 17 is fixed with a gear 15, and the other end of the connecting shaft 14 passes through the fixing plate 6 and is connected to a second fixing handle 16. The inner sides of the two inserts 17 are fixed with toothed plates 18, and the two toothed plates 18 mesh with the gear 15.

[0058] After the positioning plate 4 is fixedly connected to the fixing plate 6, the second fixing handle 16 can be turned to drive the connecting shaft 14 to rotate. Then the connecting shaft 14 drives the gear 15 to rotate, which in turn drives the upper and lower gear plates 18 to move. Then the gear plates 18 drive the insert column 17 to move, so that the upper and lower insert columns 17 can move towards each other. After that, the insert column 17 passes through the channel 19 and is inserted into the slot 20 on the positioning plate 4 for further limiting and fixing. This greatly improves the tightness between the support base 3 and the beam base 5. It is not only simple and convenient to operate and has high construction efficiency, but also can effectively ensure the stability and reliability of the steel structure corridor support connection under multiple fixed connections.

[0059] A limiting block 25 is fixed to one end of the insertion post 17 relative to the toothed plate 18, and a limiting groove 26 matching the limiting block 25 is provided on the inner wall of the cavity 13. Through the cooperation of the limiting block 25 and the limiting groove 26, the insertion post 17 can be limited and guided to ensure the stability of the insertion post 17 when it moves.

[0060] Both ends of the cavity 13 are provided with sliding cavities 21 facing the insertion post 17. A connecting block 23 is slidably connected inside the sliding cavity 21. One end of the connecting block 23 extends outside the sliding cavity 21 and is fixedly connected to the insertion post 17. A first spring 22 is fixed inside one end of the sliding cavity 21. One end of the first spring 22 is fixedly connected to the connecting block 23. A guide rod 24 is connected through the first spring 22 and the connecting block 23. Both ends of the guide rod 24 are fixedly connected to the inner wall of the sliding cavity 21.

[0061] By rotating the second fixing handle 16 in the opposite direction, the two inserts 17 can be brought closer together and retracted into the cavity 13. Then, the inserts 17 can drive the connecting block 23 to slide along the guide rod 24, causing the connecting block 23 to squeeze the first spring 22. At this time, the first spring 22 contracts and deforms. When the inserts 17 extend out of the cavity 13 again, under the elastic compensation of the first spring 22, the inserts 17 can be further prevented from moving, thereby greatly improving the stability of the structure during connection.

[0062] refer to Figures 1-11 As shown, a connection method for a steel structure corridor support connection device includes the following specific steps:

[0063] S1. By placing the support base 3 between the tops of the two fixing plates 6 on the beam seat 5, the two positioning plates 4 are in a retracted and close-fitting state. Then, the first fixing handle 2 is turned, causing the first fixing handle 2 to drive the bidirectional screw 28 to rotate. Under the action of the two reverse threads, the bidirectional screw 28 can drive the two fixing blocks 29 to move in opposite directions. Then, the fixing blocks 29 drive the positioning plates 4 to move, so that the two positioning plates 4 move away from each other and abut against the side fixing plates 6. Then, the card plate 7 on the inner side of the fixing plate 6 is fitted into the card groove 8 on the inner side of the positioning plate 4, so that the positioning plate 4 and the fixing plate 6 can be locked together to achieve quick fixation between the support base 3 and the beam seat 5.

[0064] S2. When the two fixed blocks 29 approach each other, the second spring 30 can be compressed and deformed. Conversely, when the two fixed blocks 29 move away from each other, the second spring 30 rebounds and is always compressed by the two fixed blocks 29, thus having a rebound force. Under the elastic action of the second spring 30, the two fixed blocks 29 can be effectively prevented from approaching and closing. Therefore, after the positioning plate 4 and the fixed plate 6 are locked, the positioning plate 4 can be effectively prevented from moving or displacing.

[0065] S3. At the same time, when the positioning plate 4 is close to the fixing plate 6, the positioning pins 9 at the four ends of the positioning plate 4 can be inserted into the positioning holes 10 at the four ends of the fixing plate 6, and the threaded section 11 on the positioning pin 9 passes through the positioning hole 10. Then, the threaded cap 12 is screwed on the threaded section 11 so that the threaded cap 12 abuts against the outer wall of the fixing plate 6, thereby greatly strengthening the connection strength between the positioning plate 4 and the fixing plate 6.

[0066] After the positioning plate 4 and the fixing plate 6 are fixedly connected, the second fixing handle 16 can be turned to drive the connecting shaft 14 to rotate. Then the connecting shaft 14 drives the gear 15 to rotate, and the gear 15 drives the upper and lower tooth plates 18 to move at the same time. Then the tooth plates 18 drive the insert 17 to move, so that the upper and lower insert 17 can move towards each other. Then the insert 17 passes through the channel 19 and is inserted into the slot 20 on the positioning plate 4 for further limiting and fixing. This greatly improves the tightness between the support 3 and the beam 5. It is not only simple and convenient to operate and has high construction efficiency, but also can effectively ensure the stability and reliability of the steel structure corridor support connection under multiple fixed connections.

[0067] S5. By rotating the second fixing handle 16 in the opposite direction, the two inserts 17 can be brought closer to each other and retracted into the cavity 13. Then, the inserts 17 can drive the connecting block 23 to slide along the guide rod 24, so that the connecting block 23 squeezes the first spring 22. At this time, the first spring 22 contracts and deforms. When the inserts 17 extend out of the cavity 13 again, under the elastic compensation of the first spring 22, the inserts 17 can be further prevented from moving, thereby greatly improving the stability of the structure during connection.

[0068] The foregoing has only described certain exemplary embodiments of the present invention by way of illustration. Undoubtedly, those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the foregoing drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.

A method of connecting a steel structure gallery support connecting device according to any one of claims 1 to 9, characterized in that, The specific steps include the following: S1, by placing the support seat (3) between the top ends of the two fixed plates (6) on the beam seat (5), at this time the two positioning plates (4) are in a folded state, then the first fixed handle (2) is twisted, the first fixed handle (2) drives the bidirectional screw rod (28) to rotate, under the action of the two opposite threads, the bidirectional screw rod (28) drives the two fixed blocks (29) to move away from each other, then the fixed blocks (29) drive the positioning plates (4) to move, so that the two positioning plates (4) move away from each other and abut against the fixed plates (6) on the sides, then the clamping plates (7) on the inner sides of the fixed plates (6) are embedded in the clamping grooves (8) on the inner sides of the positioning plates (4), so that the positioning plates (4) and the fixed plates (6) can be locked to realize the quick fixing between the support seat (3) and the beam seat (5); S2, when the two fixed blocks (29) move close to each other, the second spring (30) can be compressed to shrink, on the contrary, when the two fixed blocks (29) move away from each other, the second spring (30) rebounds and always receives the compression of the two fixed blocks (29) to have a rebounding force, under the elastic action of the second spring (30), the two fixed blocks (29) can be effectively prevented from moving close to each other, and after the positioning plates (4) and the fixed plates (6) are locked, the positioning plates (4) can be effectively prevented from moving; S3, at the same time, when the positioning plates (4) move close to the fixed plates (6), the positioning columns (9) at four ends of the positioning plates (4) can be inserted into the positioning holes (10) at four ends of the fixed plates (6), and the threaded sections (11) on the positioning columns (9) pass through the positioning holes (10), then the threaded caps (12) are screwed on the threaded sections (11), so that the threaded caps (12) abut against the outer wall of the fixed plates (6), thereby greatly enhancing the connection strength between the positioning plates (4) and the fixed plates (6). S4, after the positioning plate (4) and the fixed plate (6) are fixedly connected, the second fixed handle (16) can be screwed to drive the connecting shaft (14) to rotate, and then the connecting shaft (14) drives the gear (15) to rotate, so that the gear (15) drives the upper and lower two toothed plates (18) to move at the same time, and then the toothed plate (18) drives the insertion column (17) to move, so that the upper and lower two insertion columns (17) can move towards each other, then the insertion column (17) passes through the channel (19) and is inserted into the insertion slot (20) on the positioning plate (4), to further limit and fix, thereby greatly improving the fastening between the support seat (3) and the beam seat (5), not only simple and convenient operation, high construction efficiency, but also under the multiple fixed connection, can effectively guarantee the stability and reliability of the steel structure corridor support connection; S5, and reverse rotation of the second fixed handle (16), namely the two insertion columns (17) are close to each other and shrink into the cavity slot (13), and then the insertion column (17) can drive the connecting block (23) to slide along the guide rod (24), so that the connecting block (23) extrudes the first spring (22), at this time the first spring (22) shrinks and deforms, when the insertion column (17) extends out of the cavity slot (13) again, under the elastic compensation of the first spring (22), the insertion column (17) can be further prevented from moving, thereby greatly improving the stability of the structure during connection.
