Abstract
Description
Technical Field
[0001] This invention relates to the field of construction component technology, and in particular to a hanging concrete pump pipe fixing device and its usage method. Background Technology
[0002] Currently, concrete is typically transported using fixed pump pipes in high-rise buildings, factories, and other construction projects. There is currently no device that can fix vertical concrete pump pipes at the top of pipes that are segmented from each floor.
[0003] When the floor height is high, pump pipe supports are usually erected from the bottom using steel pipes and fasteners, or they can be left unsecured. The former involves a cumbersome and time-consuming scaffolding process, which is difficult to carry out in narrow spaces, while the latter is prone to pump pipe cracking due to the lack of securing measures, posing certain safety hazards, as detailed below: (1) When traditionally supporting pump pipes, due to the limited floor height, the upper section of the pump pipe is often not fixed, or only the reserved opening is filled with materials such as wooden blocks for simple fixation. When pumping concrete for a long time, the pump pipe vibrates and the wooden blocks are easily rubbed off and lose their fixing function. If the pumping is not effectively fixed for a long time, the pump pipe joint will become loose or even break. (2) When the traditional fixed mode uses manual erection of pump pipe frame, the frame needs to be erected at a high height when the floor height is high, otherwise it is difficult to effectively fix the upper pump pipe; (3) The transfer of the traditional fixed form of pump pipe rack requires the removal of the outriggers and scaffolding and then the reconstruction, which is a complicated process that is time-consuming and labor-intensive. (4) In the traditional pump pipe rack, the steel pipe and fastener are rigidly connected, which cannot effectively buffer the vibration of the pump pipe. Long-term pumping will also have a certain impact on the stability of the rack. Summary of the Invention

A positioning steel plate is installed at the lower part of the floor, and the pump pipe passes through the middle of the positioning steel plate; the positioning steel plate determines the position of the pump pipe. The elastic support frame has one end movably connected to the side wall of the first clamp, and the other end rotatably connected to the lower part of the positioning steel plate; the elastic support frame serves as a buffer. A fixing plate is fitted onto the floor, and the upper part of the fixing plate is fixedly connected to the second clamp. The lower part of the fixing plate is fixedly connected to the positioning steel plate. The fixing plate serves to fix components such as pump pipes and positioning steel plates.
[0005] Preferably, the positioning steel plate includes a second plate body, the second plate body having a second through hole in its center, and the pump pipe passing through the second through hole. The second through hole is located in the center of the second plate body, thus positioning the pump pipe.
[0006] Preferably, the fixing plate includes a U-shaped component that hugs the edge of the floor. A second screw is fixedly connected to the lower part of the U-shaped component. A sliding hole is provided on the second plate, through which the second screw passes and is secured with a nut.

[0007] Preferably, a vertical plate is fixedly connected to the upper part of the U-shaped part, and a first screw is fixedly connected to the side wall of the second clamp. The first screw passes through the vertical plate and is fixed with a nut.
[0008] Preferably, the elastic support frame is provided with a second connecting ear and a third connecting ear at both ends, the side wall of the first clamp is provided with a first connecting ear, and the lower part of the second plate is fixedly connected with a fifth connecting ear.

[0009] Preferably, the sidewall of the second plate is provided with an extended steel plate, the extended steel plate including a first plate, on which a fourth connecting lug is provided, and also an elastic support frame and a first clamp connected to the extended steel plate. The elastic support frame has a second connecting lug and a third connecting lug at each end, and the sidewall of the first clamp has a first connecting lug. The second and third connecting lugs respectively fit onto the first and fourth connecting lugs. That is, other elastic supports and first clamps are also provided, connected to the extended steel plate, improving the overall stability of the device.
[0010] Preferably, one end of the second connecting ear is fixedly connected to a pipe fitting, one end of the third connecting ear is fixedly connected to a telescopic rod, and the other end of the telescopic rod is fixedly connected to a limit block. A first spring and a second spring are respectively provided on both sides of the limit block, and the other ends of the first spring and the second spring abut against the inner wall of the pipe fitting.

By using connecting steel plates to increase or decrease the number of supports, the range of support under the bracket can be adjusted according to changes in floor height; 3. The combination of standardized pump pipe clamps and elastic support frames acts as a buffer, ensuring stable installation; 4. Simple to operate and easy to move, improving work efficiency. The position of the fixing clamp can be flexibly adjusted, and it is less affected by the limitation of construction space. Attached Figure Description

[0018] like Figures 1 to 8 As shown, a hanging concrete pump pipe fixing device includes a pump pipe 2, which is used for pumping concrete. The pump pipe 2 passes through a pre-set hole in the floor to pump concrete to the construction area below the floor. It also includes: The first clamp 1 is fixedly connected to the lower side wall of the pump pipe 2. The first clamp 1 has a two-part structure and is fixed to the side wall of the pump pipe 2 by bolts and nuts. The second clamp 8 is fixedly connected to the upper side wall of the pump pipe 2. Similarly, the second clamp 8 is also a two-part structure, which is fixed to the side wall of the pump pipe 2 by bolts and nuts. Positioning steel plate 7 is set at the bottom of the floor. Positioning steel plate 7 is a square piece, and the size of positioning steel plate 7 is larger than the size of the floor opening. Pump pipe 2 passes through the middle of positioning steel plate 7. The elastic support frame 3 has an axial dimension that can be changed. One end of the elastic support frame 3 is movably connected to the side wall of the first clamp 1, and the other end of the elastic support frame 3 is rotatably connected to the lower part of the positioning steel plate 7, providing support and buffering to ensure the stable installation of the pump pipe 2. The fixing plate 6 is fitted onto the floor, meaning the fixing plate 6 is fixed to the floor. The upper part of the fixing plate 6 is fixedly connected to the second clamp 8. The connection between the fixing plate 6 and the second clamp 8 enables the fixing plate 6 to support and fix the pump pipe 2. The lower part of the fixing plate 6 is fixedly connected to the positioning steel plate 7, thus fixing the positioning steel plate 7.
[0019] The positioning steel plate 7 includes a second plate body 71, and a second through hole 72 is provided in the middle of the second plate body 71. The pump pipe 2 passes through the second through hole 72. The second through hole 72 is provided to allow the pump pipe 2 to pass through.

The second plate 71 is provided with a sliding hole 73, which is a long through hole. The second screw 63 passes through the sliding hole 73 and is fixed with a nut. During installation, the fixing plate 6 is pre-clamped with the edge of the hole, and then the positioning steel plate 7 is lifted from bottom to top so that the second screw 63 passes through the sliding hole 73. The nut is used to engage the second screw 63 so that the nut supports the positioning steel plate 7. Then, the positions of the fixing plate 6 and the positioning steel plate 7 are further adjusted so that the second through hole 72 is in the designed position. Finally, the nut is tightened to make the fixing plate 6 and the positioning steel plate 7 firmly fixed on the floor.

The other end of the telescopic rod 36 is fixedly connected to the limit block 34. A first spring 33 and a second spring 35 are respectively provided on both sides of the limit block 34, and the other ends of the first spring 33 and the second spring 35 abut against the inner wall of the pipe fitting 32. The springs on both sides enable the telescopic rod 36 to return to its original position after reciprocating motion. In addition, the springs also serve as a buffer. Furthermore, the elastic support frame 3 can be replaced with a spring damping rod or similar component, which, in addition to buffering, also has a shock absorption function.
[0025] The first plate 41 has a first through hole 43 on its edge, and the second plate 71 has a third through hole 75 on its edge. The edges of the first plate 41 and the second plate 71 are clamped together by a connecting steel plate 5. There are two connecting steel plates 5, which clamp the first plate 41 and the second plate 71 from the top and bottom. Bolts are inserted through the connecting steel plates 5 and pass through the first through hole 43 and the third through hole 75. With the help of bolt nuts, the first plate 41 and the second plate 71 are fixedly connected.
[0026] A buffer rubber pad 9 is provided at the upper end of the first plate 41 and / or the second plate 71. The upper end of the buffer rubber pad 9 abuts against the lower end of the floor, which plays a role in buffering and shock absorption.
