Description

Technical Field

[0001] The present application relates to the field of steel structure buildings, and more specifically, to an auxiliary device for the construction and installation of a building steel beam node structure. Background Art

[0002] Steel beam buildings are new buildings with a steel material framework. Compared with traditional concrete buildings, steel plates or steel sections are used to replace reinforced concrete, which has higher strength and better seismic resistance. When installing and connecting existing steel beam nodes, on the one hand, a crane is needed to lift the steel beam, and on the other hand, workers need to pull the steel beam with a rope to limit its position to prevent it from shaking during installation. This not only takes time and effort but also has poor stability. The patent document with the publication number CN220014517U in the prior art provides an auxiliary positioning device for building steel beam installation. By rotating the handle, the adjusting frame is driven to rotate. At this time, the two adjusting screws move in opposite or opposite directions, and the first mounting frame and the second mounting frame are driven to move to both sides through the fixing plate, so that the device can be used for building steel beams of different sizes and specifications, and has a wide range of applications.

[0003] Regarding the above related technology, the inventor believes that after the device horizontally limits the steel beam by the mutual approach of the two mounting frames, it is necessary to rotate the fastening bolt to longitudinally limit the steel beam, and the operation is relatively cumbersome, which is not conducive to improving work efficiency. Therefore, we propose an auxiliary device for the construction and installation of a building steel beam node structure. Summary of the Utility Model

[0004] In order to improve the problems proposed in the above background art, the present application provides an auxiliary device for the construction and installation of a building steel beam node structure, and adopts the following technical solutions:

[0005] An auxiliary device for the construction and installation of a building steel beam node structure includes a fixed seat. A bidirectional screw is rotatably connected to the fixed seat. Two sliders are slidably connected in the fixed seat. The sliders are threadedly connected to the bidirectional screw. Two rib plates are fixedly connected to the sliders. A rack is slidably connected between the two rib plates. One end of the rack is fixedly connected to a top plate A, and the top plate A is used for horizontally limiting the steel beam. One side of the rack is meshed with a gear, the gear is rotatably connected to the rib plate, a connecting rod is fixedly connected to the gear, and one end of the connecting rod is hinged to a top plate B, and the top plate B is used for longitudinally limiting the steel beam.

[0006] By adopting the above technical solution, after placing the fixed seat at the butt joint of two steel beams, rotate the bidirectional screw to drive the two sliders to approach each other, so that the rib plate drives the top plate A and the top plate B to move. The top plate A first abuts against the side of the steel beam, and then the rack moves to drive the gear to rotate, so that the connecting rod drives the top plate B to rotate until it abuts against the flange of the steel beam. The two top plates A cooperate to limit the side of the two steel beams by abutting, and the two top plates B cooperate with the fixed seat to limit the flange of the steel beam by abutting, realizing horizontal and vertical limits.

[0007] Optionally, the end of the bidirectional screw penetrates through the fixed seat and is fixedly connected with a handwheel.

[0008] Optionally, sliding rods are fixedly connected to both sides of the top plate A. The sliding rods are slidably connected to the rib plate, and springs are sleeved on the sliding rods. The two ends of the springs are respectively fixedly connected to the rib plate and the top plate A.

[0009] By adopting the above technical solution, the sliding rods enable the rack to slide straight. After the top plate A does not abut against the steel beam, the spring can stretch to drive the top plate A to reset.

[0010] Optionally, the connecting rod has a bent structure, and a reinforcing rod is fixedly connected to the connecting rod.

[0011] By adopting the above technical solution, when the connecting rod rotates, it can drive the top plate B to abut against the bottom surface of the upper flange of the steel beam, and the reinforcing rod can enhance the stress strength of the connecting rod.

[0012] Optionally, limit disks are fixedly connected to both ends of the bidirectional screw. A brake plate with a clamping fit is arranged on one side of the limit disk. A pull rod is fixedly connected to the brake plate, and the pull rod is slidably connected to the fixed seat.

[0013] By adopting the above technical solution, a plurality of card slots are arranged at equal intervals in a ring shape on the limit disk. When the pull rod moves to drive the brake plate to be clamped with the limit disk, the brake plate is clamped with the card slots, so that the bidirectional screw connected to the limit disk cannot rotate, improving the limit stability of the top plate A and the top plate B to the steel beam.

[0014] In summary, the present application includes at least one of the following beneficial technical effects:

[0015] 1. When the two sliders are driven to approach by rotating the bidirectional screw, the two top plates A approach each other and abut against the side of the steel beam. When the sliding continues to move, the rack drives the gear to rotate, so that the connecting rod drives the top plate B to abut against the bottom surface of the flange of the steel beam, thereby realizing rapid horizontal and vertical limits of the steel beam, with simple operation and convenient use.

[0016] 2. When the two pull rods approach each other, the brake plate is clamped with the limit disk, and the limit disk cannot rotate, so that the bidirectional screw cannot drive the slider to slide, thereby improving the stability when the top plate A and the top plate B contact the steel beam.

[0022] The following further describes the present application in detail with reference to the accompanying drawings of the specification.

[0023] Referring to Figures 1-4 , the present application includes a fixed seat 1. A bidirectional screw 2 is rotatably connected to the fixed seat 1. Two slide blocks 4 are slidably connected in the fixed seat 1. The slide blocks 4 are threadedly connected to the bidirectional screw 2. Two rib plates 5 are fixedly connected to the slide blocks 4. A rack 6 is slidably connected between the two rib plates 5. One end of the rack 6 is fixedly connected to a top plate A 7. The top plate A 7 is used for horizontally limiting the steel beam. A gear 10 is meshed and connected to one side of the rack 6. The gear 10 is rotatably connected to the rib plate 5. A connecting rod 11 is fixedly connected to the gear 10. One end of the connecting rod 11 is hinged to a top plate B 13. The top plate B 13 is used for longitudinally limiting the steel beam. After placing the fixed seat 1 at the butt joint of two steel beams, rotate the bidirectional screw 2 to drive the two slide blocks 4 to approach each other, so that the rib plates 5 drive the top plate A 7 and the top plate B 13 to move. The top plate A 7 first abuts against the side of the steel beam, and then move the rack 6 to drive the gear 10 to rotate, so that the connecting rod 11 drives the top plate B 13 to rotate until it abuts against the flange of the steel beam. The two top plates A 7 cooperate to abut and limit the sides of the two steel beams, and the two top plates B 13 cooperate with the fixed seat 1 to abut and limit the flanges of the steel beam, realizing horizontal and longitudinal limits.

[0024] Referring to Figure 2 , the end of the bidirectional screw 2 passes through the fixed seat 1 and is fixedly connected to a handwheel 3.

[0025] Refer to Figure 3 , on both sides of the top plate A7, sliding rods 8 are fixedly connected. The sliding rods 8 are slidably connected to the rib plates 5. A spring 9 is sleeved on the sliding rods 8. Both ends of the spring 9 are fixedly connected to the rib plate 5 and the top plate A7 respectively. The sliding rods 8 enable the rack 6 to slide straightly. After the top plate A7 does not abut against the steel beam, the extension of the spring 9 can drive the top plate A7 to reset.

[0026] Refer to Figure 2 , the connecting rod 11 has a bent structure, and a reinforcing rod 12 is fixedly connected to the connecting rod 11. When the connecting rod 11 rotates, it can drive the top plate B13 to abut against the bottom surface of the upper wing plate of the steel beam. The reinforcing rod 12 can enhance the stress strength of the connecting rod 11.

[0027] Refer to Figure 4 , at both ends of the bidirectional screw rod 2, limit discs 14 are fixedly connected. On one side of the limit disc 14, there is a brake plate 15 with a snap-fit connection. A pull rod 16 is fixedly connected to the brake plate 15. The pull rod 16 is slidably connected to the fixed seat 1. A plurality of card slots are formed in the limit disc 14 at equal intervals in a ring shape. When the pull rod 16 moves to drive the brake plate 15 to be snap-fitted with the limit disc 14, the brake plate 15 is snap-fitted with the card slots, so that the bidirectional screw rod 2 connected to the limit disc 14 cannot rotate, improving the limit stability of the top plate A7 and the top plate B13 to the steel beam.

[0028] The implementation principle of an auxiliary device for the construction and installation of a building steel beam joint structure in an embodiment of the present application is as follows: after two steel beams are butted, the fixed seat 1 is placed on the upper side of the joint of the two steel beams. Rotate the handwheel 3 to drive the bidirectional screw rod 2 to rotate. The bidirectional screw rod 2 drives the two sliders 4 to approach each other. The rib plate 5 drives the top plate A7 to first abut against the side of the steel beam. The two top plates A7 cooperate to perform lateral limitation on the two steel beams. The rack 6 drives the gear 10 to rotate, so that the connecting rod 11 drives the top plate B13 to rotate to the bottom surface of the upper wing plate of the steel beam. The fixed seat 1 and the top plate B13 cooperate to perform longitudinal limitation on the two steel beams.
