Description

Technical Field

[0001] This utility model relates to the technical field of concrete construction, and in particular to a pump pipe vibration damping device for use in buildings. Background Technology

[0002] Currently, in the concrete pouring process of high-rise buildings, ground pumps are typically used to transport concrete. The pump pipes need to pass through the floor slabs and ascend to the floor surface for pouring. Because of the vibration generated during concrete pumping, the vibration of the pump pipes can affect the floor slabs. Therefore, how to mitigate the impact of pump pipe vibration on the floor slabs is a key research focus. Utility Model Content

[0003] In order to improve the impact of pump pipe vibration on the floor slab, this utility model provides a pump pipe vibration damping device for use in buildings.

[0004] The present invention provides a pump pipe vibration damping device for use in buildings, which adopts the following technical solution:

[0005] A pump pipe vibration damping device for use in buildings includes a base plate detachably fixed to a floor slab. A clearance hole is provided in the center of the base plate. Positioning columns are vertically fixed at the four corners of the top surface of the base plate. A mounting plate with a notch is installed on each positioning column. A second conduit is fixed to the surface of the mounting plate. A damping spring damper and a clamp for fixing the pump pipe are installed in conjunction with the mounting plate. When the device is used to fix a horizontally positioned pump pipe, the mounting plate is horizontally fitted onto the positioning columns, the damping spring damper is vertically installed between the mounting plate and the base plate, and the clamp is installed on the top surface of the mounting plate. When the device is used to fix a vertically positioned pump pipe, the mounting plate is vertically positioned, the second conduit is fitted onto the positioning columns, and the damping spring damper is horizontally positioned. One end of the damping spring damper is connected to the mounting plate, and the other end is connected to the clamp.

[0006] By adopting the above technical solution, the device can be flexibly adapted to both vertically and horizontally installed pump pipes. The use of damping spring shock absorbers, combined with clamps to fix the pump pipes, can effectively improve the impact of the pump pipes on the floor slabs during concrete pumping.

[0007] Optionally, a first conduit is vertically fixed to the side of the mounting plate opposite to the second conduit, and the first conduit is detachably sleeved on the positioning post.

[0008] By adopting the above technical solution, the conduit is set on the positioning post, which can improve the stability when the mounting plate moves up and down.

[0009] Optionally, a positioning nut is threaded onto the top of the positioning post.

[0010] By adopting the above technical solution, the positioning nut is used in conjunction with the positioning post, which improves the stability of the mounting plate after installation.

[0011] Optionally, the locating nut is a washer nut.

[0012] By adopting the above technical solution, the washer-loaded nut increases the force-bearing area.

[0013] Optionally, the positioning post is fitted with a shock-absorbing washer for engaging with the positioning nut.

[0014] By adopting the above technical solution, vibration damping pads are installed to further reduce vibration.

[0015] Optionally, the top surface of the base plate is covered with a shock-absorbing pad.

[0016] By adopting the above technical solution, vibration damping pads are installed to further reduce vibration.

[0018] By adopting the above technical solution, the upper hoop plate and the lower hoop plate are connected by bolts, which can effectively fix the pump pipe.

[0019] Optionally, a shock-absorbing block is provided on the side of the lower hoop plate away from the upper hoop plate, and the shock-absorbing block is connected to the lower hoop plate by fixing screws.

[0026] The following combination Figures 1-4 The present invention will be described in further detail below.

[0027] This utility model discloses a vibration damping device for pump pipes used in buildings. (Refer to...) Figure 1 and Figure 2 The pump pipe vibration damping device used in the building is used in conjunction with the floor slab and the pump pipe 1. The device includes a base plate 2, which is fixed to the floor slab by expansion bolts. A circular clearance hole 20 is opened in the center of the base plate 2, through which the pump pipe 1 can pass. The top surface of the base plate 2 is covered with a rubber vibration damping pad 3, which has the same shape as the base plate 2.

[0028] Reference Figure 1 and Figure 2 At each of the four corners of the top surface of the base plate 2, a positioning post 4 is vertically fixed. A mounting plate 5 is installed on each of the two positioning posts 4 located on the same side, resulting in two mounting plates 5 in total. A semi-circular notch is provided on the side of each mounting plate 5 closest to each other, allowing the pump pipe 1 to pass through. When this device is used with the horizontally positioned pump pipe 1, the mounting plate 5 is horizontally positioned, and the positioning posts 4 are vertically inserted into the mounting plate 5. A conduit 50 is vertically fixed to the bottom surface of the mounting plate 5, and the conduit 50 is fitted onto the positioning post 4.

[0029] Reference Figure 1 and Figure 2 The top of the positioning post 4 is threaded with a positioning nut 6. In this embodiment, the positioning nut 6 is a washer nut. The positioning nut 6 is fitted with a rubber damping pad 7 sleeved on the positioning post 4. A damping spring shock absorber 8 is bolted between the middle of the bottom surface of the mounting plate 5 and the base plate 2. In this embodiment, the damping spring shock absorber 8 can be a commercially available product, such as the JA type damping spring shock absorber with product model JA-1-100~JA-9-10800.

[0030] Reference Figures 1-3 The top surface of the mounting plate 5 is also bolted with clamps 9. The clamps 9 include an upper clamp plate 90 and a lower clamp plate 91 in a semi-circular arc shape. The ends of the upper clamp plate 90 and the lower clamp plate 91 are fixed by connecting bolts 92 and connecting nuts 93. The pump pipe 1 is horizontally inserted and fixed inside the two clamps 9. A rubber shock absorber 94 is provided at the bottom of the lower clamp plate 91. The shock absorber 94 is adapted to the lower clamp plate 91 and is connected to the lower clamp plate 91 by fixing screws 95.

[0031] Reference Figure 1 and Figure 4Two parallel conduits 51 are fixed to the top surface of the mounting plate 5. When the device is used in conjunction with the vertically arranged pump pipe 1, the mounting plate 5 is vertically arranged, the conduits 51 are sleeved on the positioning column 4 and fixed by the positioning nut 6, the damping spring shock absorber 8 is horizontally bolted on the mounting plate 5, the two damping spring shock absorbers 8 are arranged in an alternating pattern, the clamps 9 are installed at the ends of the damping spring shock absorbers 8, and the pump pipe 1 is vertically inserted and fixed inside the two clamps 9.

[0032] The implementation principle of the pump pipe vibration damping device for use in buildings according to this utility model embodiment is as follows: the device can be flexibly adapted to both vertically and horizontally arranged pump pipes 1. When used with a horizontally arranged pump pipe 1, the base plate 2 is fixed to the floor slab, the mounting plate 5 is horizontally arranged, the damping spring shock absorber 8 is vertically installed between the mounting plate 5 and the base plate 2, and the clamp 9 is installed on the top surface of the mounting plate 5.

[0033] When used in conjunction with the vertically installed pump pipe 1, the base plate 2 is fixed to the pre-reserved opening in the floor slab, the mounting plate 5 is vertically installed, the damping spring shock absorber 8 is horizontally installed, and the clamp 9 is installed at the end of the damping spring shock absorber 8. By using the damping structure such as the damping spring shock absorber 8, the damping pad 3, and the damping shim 7, and in conjunction with the clamp 9 to fix the pump pipe 1, the impact of the pump pipe 1 on the floor slab during concrete pumping can be effectively reduced.

[0034] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
