Description

Technical Field

[0001] This invention relates to the field of steel structure construction technology, specifically to a steel structure pre-embedded bolt positioning mechanism. Background Technology

[0002] In the main steel structure of a building, the steel columns and the foundation are connected by pre-embedded bolts. The installation accuracy of the pre-embedded bolts directly affects the foundation accuracy of the entire building. Therefore, the installation accuracy requirements for the pre-embedded bolts are very high. If the pre-embedding deviation exceeds the allowable range, the holes on the base plate of the steel column will not correspond to the anchor bolts, affecting the subsequent construction quality of the main steel structure. Therefore, a positioning mechanism is needed to position the pre-embedded bolts during the construction and fixing process.

[0003] Currently, the steel structure pre-embedded bolt positioning mechanism used in steel structure construction generally adopts multiple rectangular steels welded into a rectangle, and corresponding sleeves are welded at the joints of two adjacent rectangular steels. A positioning head for positioning the horizontal and vertical of the pre-embedded bolts is installed inside the sleeve. The length and width of the steel frame welded by this positioning mechanism cannot be adjusted, and the spacing of the pre-embedded bolts will also be affected by the magnitude of the force on the supporting steel frame. It cannot be adjusted according to the spacing of the pre-embedded bolts. The rectangular steel, sleeves and other materials cannot be disassembled after being shaped, and cannot be recycled, which easily leads to the waste of materials. Summary of the Invention

[0004] To address the problems existing in the prior art, a steel structure pre-embedded bolt positioning mechanism is provided.

[0005] The technical solution adopted by this invention to solve its technical problem is:

[0006] This invention proposes a positioning mechanism for pre-embedded bolts in steel structures, comprising several adjusting cylinders and several sliding sleeves. Each adjusting cylinder is fixedly connected to two mutually perpendicular support rods. The sliding sleeves are located between the adjusting cylinders, and the ends of the support rods of adjacent adjusting cylinders that are close to each other are slidably disposed within the sliding sleeves. Each adjusting cylinder is detachably connected to a positioning sleeve, and the positioning sleeve is threadedly connected to a threaded sleeve, which is threadedly connected to a pre-embedded bolt.

[0007] Preferably, the support rod has a locking groove, and the sliding sleeve is threaded with a bolt, which passes through the outer wall of the sliding sleeve and abuts against the locking groove.

[0008] Preferably, the adjusting cylinder is detachably connected to a level via Velcro.

[0009] Preferably, the adjusting cylinder is rotatably connected to horizontally arranged lead screws at both ends, the lead screws are fitted with lead screw nuts, the lead screw nuts are slidably connected to the adjusting cylinder, and the lead screw nuts are fixedly connected to clamping plates that can hold the positioning sleeve.

[0010] Preferably, the positioning sleeve has a locking hole, and the clamping plate is fixedly connected to a locking block that can slide into the locking hole.

[0011] Preferably, the adjusting cylinder is rotatably connected to a vertically arranged adjusting rod, which can drive two lead screws to rotate simultaneously, thereby driving the two clamping plates to move towards or away from each other.

[0012] Preferably, the lead screw is fixedly sleeved with a second bevel gear, the adjusting rod is fixedly sleeved with a first bevel gear, the second bevel gear and the first bevel gear mesh with each other, and the upper end of the adjusting rod extends out of the adjusting cylinder and is connected to a knob.

[0013] Preferably, the positioning sleeve is threadedly connected to a connecting block, and the adjusting cylinder is rotatably connected to a gripper that can clamp the connecting block. The gripper is connected to the adjusting cylinder via a torsion spring, and the bottom end of the gripper has an inclined surface.

[0014] Preferably, the adjusting cylinder is slidably connected to a sliding plate, the sliding plate is connected to the adjusting cylinder via a tension spring, and the sliding plate is fixedly connected to a magnet that can slide into the gripper, the magnet having an attractive effect on the connecting block.

[0015] Preferably, the slide is fixedly connected to an unlocking block, and the upper end of the gripper is provided with a horizontal surface that can contact both sides of the magnet. When the magnet slides below the horizontal surface, the unlocking block and the gripper come into contact.

[0016] Compared with the prior art, the beneficial effects of the present invention are:

[0017] 1. This application is equipped with a sliding support rod. By loosening the bolts, the support rod can slide within the sliding sleeve, allowing for adjustment of the spacing between adjacent embedded bolts. The included level allows for adjustment of the height of the embedded bolts by rotating the threaded sleeve, facilitating the maintenance of the overall levelness of the device. It is easy to operate, suitable for positioning embedded bolts of different specifications, and allows for flexible adjustment of the spacing between embedded bolts.

[0018] 2. This application is equipped with a lead screw. By rotating the adjusting rod, the lead screw can be driven to rotate. The lead screw can drive the clamping plate to move inward or outward at the same time, which can realize the clamping work of the positioning sleeve and facilitate the separation of the positioning sleeve and the adjusting cylinder. The positioning sleeve of appropriate size can be selected according to actual needs, making the device more flexible in use. It ensures that the main materials of the positioning mechanism can be recycled, effectively improving the resource utilization rate.

[0019] 3. This application is equipped with a magnet. The positioning sleeve can drive the gripper to rotate. The gripper can clamp the connecting block. The connecting block has an attractive effect on the magnet, which can drive the magnet to move between the grippers. At this time, the lower end of the gripper cannot be opened, so the connecting block can be fixed. When disassembling, just press down on the slide plate to drive the gripper to open, which can realize the quick disassembly of the positioning sleeve and the clamping effect is good.

Detailed Implementation

[0030] Embodiments of the present invention are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0031] like Figures 1-7 As shown in the figure, this embodiment proposes a positioning mechanism for pre-embedded bolts in steel structures, including several adjusting cylinders 1 and several sliding sleeves 2, wherein there are four adjusting cylinders 1 and four sliding sleeves 2, and the four adjusting cylinders 1 are located at four opposite corners.

[0032] The adjusting cylinder 1 is fixedly connected to two mutually perpendicular support rods 3. The sliding sleeve 2 is located between the adjusting cylinders 1. The ends of the support rods 3 of adjacent adjusting cylinders 1 that are close to each other are slidably set in the sliding sleeve 2. One adjusting cylinder 1 corresponds to two support rods 3. Two support rods 3 are slidably connected in one sliding sleeve 2. Several adjusting cylinders 1 and several support rods 3 cooperate with each other to form a quadrilateral structure.

[0033] The support rod 3 has a locking groove 4, and the sliding sleeve 2 is threaded with a bolt 6. The bolt 6 passes through the outer wall of the sliding sleeve 2 and abuts against the locking groove 4. By tightening the bolt 6, the bolt 6 can abut against the locking groove 4, which can lock the support rod 3. By loosening the bolt 6, the support rod 3 can slide inside the sliding sleeve 2, thereby adjusting the distance between the adjusting cylinders 1.

[0034] The adjusting cylinder 1 is detachably connected to the level 5 via Velcro 17. The level 5 can be disassembled via Velcro 17, making it easy to replace. There are four levels 5 in total, which makes it easy to observe the overall levelness of the device.

[0035] The adjusting cylinder 1 is detachably connected to a positioning sleeve 7, the positioning sleeve 7 is threadedly connected to a threaded sleeve 8, and the threaded sleeve 8 is threadedly connected to a pre-embedded bolt 9. By using the threaded sleeve 8, the height of the pre-embedded bolt 9 can be adjusted. By rotating the threaded sleeve 8, the distance of the threaded sleeve 8 from the positioning sleeve 7 can be adjusted, thereby cooperating with the level 6 to achieve the overall levelness adjustment of the device.

[0036] By loosening the bolt 6, the support rod 3 can slide within the sliding sleeve 2, allowing for adjustment of the spacing between adjacent embedded bolts 9. The level 5, when rotated by the threaded sleeve 8, allows for adjustment of the height of the embedded bolts 9, facilitating the maintenance of the overall levelness of the device. It is easy to operate, suitable for positioning embedded bolts 9 of different specifications, and allows for flexible adjustment of the spacing between embedded bolts 9.

[0037] The adjusting cylinder 1 is rotatably connected to two ends of a horizontally arranged lead screw 12. The lead screw 12 is fitted with a lead screw nut 14. The lead screw nut 14 and the adjusting cylinder 1 are slidably connected. The lead screw nut 14 is fixedly connected to a clamping plate 15 that can clamp the positioning sleeve 7. The lead screw nut 14 can only slide in the horizontal direction. Therefore, when the lead screw 12 rotates, it can drive the clamping plate 15 to move.

[0038] The positioning sleeve 7 has a locking hole, and the clamping plate 15 is fixedly connected to a locking block 16 that can slide into the locking hole. There can be several locking holes and locking blocks 16, and the locking blocks 16 and the locking holes correspond one-to-one. When the clamping plate 15 moves, the locking block 16 can be moved into the locking hole.

[0039] The adjusting cylinder 1 is rotatably connected to a vertically arranged adjusting rod 10. The adjusting rod 10 can drive two lead screws 12 to rotate simultaneously, thereby driving the two clamping plates 15 to move towards or away from each other, thus realizing the clamping and releasing of the positioning sleeve 7.

[0040] The lead screw 12 is fixedly sleeved with the second bevel gear 13, and the adjusting rod 10 is fixedly sleeved with the first bevel gear 11. The second bevel gear 13 and the first bevel gear 11 mesh with each other. The upper end of the adjusting rod 10 passes through the adjusting cylinder 1 and is connected to a knob. The adjustment rod 10 can be easily rotated by the knob.

[0041] The positioning sleeve 7 is threadedly connected to the connecting block 24, and the adjusting cylinder 1 is rotatably connected to the gripper 22 that can clamp the connecting block 24. The gripper 22 is connected to the adjusting cylinder 1 through a torsion spring, and the bottom end of the gripper 22 is provided with a bevel.

[0042] The adjusting cylinder 1 is rotatably connected to the rotating shaft 23, and the rotating shaft 23 is fixedly connected to the gripper 22. The gripper 22 can rotate around the rotating shaft 23. One end of the torsion spring is connected to the gripper 22, and the other end of the torsion spring is connected to the adjusting cylinder 1. In the initial state, under the action of the torsion spring, the gripper 22 is in a state of mutual contact. When the connecting block 24 moves upward, the inclined plane can drive the gripper 22 to rotate. Then, under the action of the torsion spring, the gripper 22 closes to achieve clamping of the connecting block 24.

[0043] The adjusting cylinder 1 is slidably connected to a slide plate 18, which can only slide vertically. The slide plate 18 is connected to the adjusting cylinder 1 via a tension spring 19. The slide plate 18 is fixedly connected to a magnet 20 that can slide into the gripper 22. The magnet 20 can attract the connecting block 24. The tension spring 19 is used for the reset of the slide plate 18. In the initial state, under the action of the tension spring 19, the magnet 20 is located above the gripper 22.

[0044] The slide plate 18 is fixedly connected to the unlocking block 21. The upper end of the gripper 22 is provided with a horizontal surface that can contact both sides of the magnet 20. When the magnet 20 slides below the horizontal surface, the unlocking block 21 and the gripper 22 contact each other. The slide plate 18 is fixedly connected to the slide rod. The upper end of the slide rod passes through the adjusting cylinder 1 and is slidably connected to the adjusting cylinder 1.

[0045] When the connecting block 24 moves between the grippers 22, it can attract the magnet 20, causing the magnet 20 to descend and stretch the tension spring 19. The tension spring 19 has sufficient elasticity to ensure that when the tension spring 19 and the attraction of the magnet 20 are balanced, the magnet 20 moves exactly between the horizontal planes. At this time, the lower end of the grippers 22 cannot open, so the connecting block 24 will not move out of the grippers 22.

[0046] Compared to the lead screw 12 method, the clamp 22 structure does not require the positioning sleeve 7 for positioning. Simply move the positioning sleeve 7 into the adjusting cylinder 7, and under the attraction of the magnet 20, the magnet 20 will automatically descend, thus automatically limiting the clamp 22. In contrast, the lead screw 12 structure requires the locking hole to be aligned with the locking block 16. The clamp 22 can achieve quick release.

[0047] A method for using a steel structure embedded bolt positioning mechanism, comprising the following steps:

[0048] S1: Connect the positioning sleeve 7 and the connecting block 24 by thread. Then insert the connecting block 24 into the adjusting cylinder 1. The connecting block 24 drives the gripper 22 to rotate. Then, under the action of the torsion spring, the gripper 22 returns to its original position, thus clamping the connecting block 24.

[0049] S2: When the connecting block 24 moves between the grippers 22, the magnet 20 descends, causing the tension spring 19 to stretch. Then the magnet 20 slides into the horizontal plane at the upper end of the grippers 22, thus limiting the upper end of the grippers 22. At this time, the unlocking block 21 is located above the grippers 22.

[0050] S3: When disassembling the positioning sleeve 7, press down on the slide plate 18. The slide plate 18 drives the magnet 20 to descend, moving the magnet 20 below the horizontal plane. Then continue to move the slide plate 18 downward. The unlocking block 21 drives the gripper 22 to rotate, causing the lower end of the gripper 22 to open. At this time, the disassembly of the positioning sleeve 7 is completed.

[0051] Although embodiments of the invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the invention, the scope of which is defined by the claims and their equivalents.
