Abstract
Description
Technical Field
[0001] This utility model relates to the field of support rod clamping technology, specifically a top clamping device for building support rods. Background Technology
[0002] Currently, during the construction process, concrete beam pouring molds require positioning support. Existing support structures generally use steel pipes or other support components for support, and a steel plate is set on top of the support component as the load-bearing plate of the mold.
[0003] Before the support rods are fixed, multiple sets of support rods are hoisted to the designated position by a crane in sequence to replace manual handling, which greatly improves the efficiency of construction.
[0004] When using cranes to lift support rods, the crane's lifting end typically clamps the outer wall of the support rod. This clamping method makes it difficult to immediately secure the support rod after it's transported to the designated location, as the clamping mechanism on the outer wall prevents immediate fixation. The clamping mechanism must be disassembled first. However, without a crane to lift the disassembled support rod, the installation process becomes quite dangerous. Therefore, we propose a top clamping device for building support rods that can clamp the support rod internally without affecting its installation and fixation. Utility Model Content
[0005] The purpose of this utility model is to provide a top clamping device for building support rods, which solves the problems mentioned in the background art.
[0006] To achieve the above objectives, the present invention provides the following technical solution: a top clamping device for a building support rod, comprising a fixed base, wherein the fixed base is distributed on the top of the cavity of the support rod, and three sets of equally spaced support frames are fixedly installed at the bottom of the fixed base, and a clamping mechanism is installed at the bottom of each of the three sets of support frames;
[0007] The clamping mechanism includes V-shaped abutments rotatably mounted on both sides of the bottom of the support frame, abutments rotatably mounted on one end of each of the two sets of V-shaped abutments, a horizontal plate fixedly mounted on the top of the abutments, a push rod rotatably mounted on the other end of each of the two sets of V-shaped abutments, and an abutment ring fixedly mounted on the other end of the push rod.
[0008] Optionally, each set of abutment rings is arc-shaped, and each set of abutment rings has a rubber pad fixedly installed on its outer wall. Each set of support frames is rotatably connected to the middle of two adjacent sets of V-shaped abutment frames.
[0009] By adopting the above technical solution, the friction between the abutment ring and the inner cavity of the support rod is further increased.
[0010] Optionally, a U-shaped frame is fixedly installed on the top of the fixed base, and a lifting rope is detachably installed on the top of the U-shaped frame, with the other end of the lifting rope connected to the crane drive end.
[0011] By adopting the above technical solution, it is convenient to hoist the support rod.
[0012] Optionally, the three sets of abutments are equidistantly distributed at the bottom of the horizontal plate, and a screw hole is provided in the middle of the horizontal plate, with a screw threaded into the screw hole.
[0013] By adopting the above technical solution, the horizontal plate can be moved up and down.
[0014] Optionally, a bearing is fixedly installed in the middle of the fixed seat, the central shaft of the bearing is fixedly installed with the top of the screw, and a lever is fixedly installed at the top of the screw.
[0015] By adopting the above technical solution, it is easier for the operator to tighten the screw.
[0016] Optionally, each of the three sets of support frames is rotatably mounted on both sides of its bottom, and the other end of each set of reinforcement frames is rotatably mounted to the side wall of the corresponding push rod.
[0017] By adopting the above technical solution, the three sets of push rods can be supported.
[0018] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:
[0019] When the horizontal plate is moved downward by the screw, the three sets of abutments distributed at the bottom of the horizontal plate will simultaneously press down on one end of the V-shaped abutment in the clamping mechanism. Since the middle of the V-shaped abutment is rotatably mounted on the support frame, the other end of each set of V-shaped abutments will push the corresponding push rod to move outward, so that the abutment rings fixedly installed on the outside of the three sets of push rods can be firmly attached to the top of the inner cavity of the support rod, tightly clamping the support rod, waiting for the crane to lift the support rod. Moreover, since the clamping mechanism clamps the top of the inner cavity of the support rod, there is no support structure on the outside of the support rod when the operator installs the support rod, making the installation of the support rod very convenient.
[0020] The three sets of support frames are rotatably mounted on both sides of the bottom, and the other end of each set of reinforcement frames is rotatably mounted to the side wall of the corresponding push rod. When multiple sets of V-shaped abutments push the corresponding push rods to move outward, the reinforcement frames rotatably mounted between the support frames and the push rods will rotate synchronously with the V-shaped abutments, effectively supporting the push rods and further increasing the firmness of the support rods after the three sets of abutments clamp them.

[0026] Please see Figure 1-3 The present invention provides a technical solution: a top clamping device for a building support rod, including a fixed seat 1, the fixed seat 1 being distributed on the top of the support rod cavity, and three sets of equally spaced support frames 13 being fixedly installed at the bottom of the fixed seat 1, with clamping mechanisms installed at the bottom of each of the three sets of support frames 13.
[0027] The clamping mechanism includes V-shaped abutments 2 rotatably mounted on both sides of the bottom of the support frame 13, abutment blocks 21 rotatably mounted on one end of the two sets of V-shaped abutments 2, a horizontal plate 22 fixedly mounted on the top of the abutment blocks 21, a push rod 23 rotatably mounted on the other end of the two sets of V-shaped abutments 2, and an abutment ring 24 fixedly mounted on the other end of the push rod 23. Each set of support frames 13 is rotatably connected to the middle of the two adjacent sets of V-shaped abutments 2.
[0028] When the screw 31 pushes the horizontal plate 22 downward, the three sets of abutments 21 distributed at the bottom of the horizontal plate 22 will simultaneously press down on one end of the V-shaped abutment 2 in the clamping mechanism. Since the middle part of the V-shaped abutment 2 is rotatably mounted on the support frame 13, the other end of each set of V-shaped abutments 2 will push the corresponding push rod 23 to move outward, so that the abutment ring 24 fixedly installed on the outside of the three sets of push rods 23 can be firmly attached to the top of the inner cavity of the support rod, tightly clamping the support rod, waiting for the crane to lift the support rod. Since the clamping mechanism clamps the top of the inner cavity of the support rod, the operator does not need to consider the lack of a support structure on the outside of the support rod when installing it, making the installation of the support rod very convenient.
[0029] In this technical solution, reinforcing frames 34 are rotatably installed on both sides of the bottom of the three sets of support frames 13. The other end of each set of reinforcing frames 34 is rotatably installed on the side wall of the corresponding push rod 23, which can support the three sets of push rods 23.
[0030] When multiple sets of V-shaped abutments 2 push the corresponding push rods 23 outward, the reinforcing frame 34, which is rotatably installed between the support frame 13 and the push rod 23, will rotate synchronously with the V-shaped abutments 2, effectively supporting the push rods 23 and further increasing the firmness of the support rods after the three sets of abutment rings 24 clamp them.
[0031] In this technical solution, three sets of abutments are equidistantly distributed at the bottom of the horizontal plate 22. A screw hole 3 is opened in the middle of the horizontal plate 22, and a screw rod 31 is installed in the internal thread of the screw hole 3, which can push the horizontal plate 22 to move up and down. A bearing 32 is fixedly installed in the middle of the fixed seat 1. The central shaft of the bearing 32 is fixedly installed with the top of the screw rod 31. A lever 33 is fixedly installed at the top of the screw rod 31 to facilitate the operator to tighten the screw rod 31.
[0032] By tightening the lever on the fixed seat 1, the screw 31 inside the bearing 32 is driven to rotate. The screw 31 is threadedly connected to the screw hole 3 in the middle of the horizontal plate 22, which can push the horizontal plate 22 to move up and down.
[0033] In this technical solution, a U-shaped frame 11 is fixedly installed on the top of the fixed base 1, and a lifting rope 12 is detachably installed on the top of the U-shaped frame 11. The other end of the lifting rope 12 is connected to the drive end of the crane, which facilitates the lifting of the support rod.
[0034] When the operator drives the crane, the U-shaped frame 11 and the lifting rope 12 fixedly installed on the top of the fixed base 1 can be used to lift the clamped support rod.
[0035] In this technical solution, each set of abutment rings 24 is arc-shaped, and each set of abutment rings 24 has a rubber pad 25 fixedly installed on its outer wall to further increase the friction between the abutment rings 24 and the inner cavity of the support rod.
[0036] Once the abutment rings 24 fixedly installed on the outer side of the three sets of push rods 23 can be firmly attached to the top of the inner cavity of the support rod, the rubber pads 25 fixedly installed on the outer wall of the three sets of abutment rings 24 further increase the friction between the abutment rings 24 and the inner cavity of the support rod, greatly improving the firmness and stability of the support rod after clamping.
[0037] In use, first place the fixing seat 1 inside the top cavity of the support rod and tighten the lever on the fixing seat 1 to drive the screw 31 inside the bearing 32 to rotate. The screw 31 is threadedly connected to the screw hole 3 in the middle of the horizontal plate 22, which can push the horizontal plate 22 to move up and down. At the same time, when the screw 31 pushes the horizontal plate 22 downward, the three sets of abutments 21 distributed at the bottom of the horizontal plate 22 will simultaneously press down on one end of the V-shaped abutment 2 in the clamping mechanism. Since the middle of the V-shaped abutment 2 is rotatably mounted on the support frame 13, the other end of each set of V-shaped abutments 2 will push the corresponding push rod 23 to move outward, so that the abutment ring 24 fixedly installed on the outside of the three sets of push rods 23 can be firmly attached to the top of the inner cavity of the support rod, tightly clamping the support rod. Hold the support rod and wait for the crane to lift it. Since the clamping mechanism clamps the top of the inner cavity of the support rod, the operator can easily install the support rod without any external support structure. At the same time, the bottom sides of the three sets of support frames 13 are rotatably installed with reinforcing frames 34, and the other end of each set of reinforcing frames 34 is rotatably installed with the side wall of the corresponding push rod 23. When the multiple sets of V-shaped abutments 2 push the corresponding push rod 23 to move outward, the reinforcing frames 34 rotatably installed between the support frame 13 and the push rod 23 will rotate synchronously with the V-shaped abutments 2, effectively supporting the push rod 23 and further increasing the firmness of the support rod after being clamped by the three sets of abutment rings 24.
