Description

Technical Field

[0001] The utility model belongs to the technical field of vibration reduction of ground pump pipelines in high-rise buildings, and in particular relates to a vibration reduction support for ground pump pipelines in high-rise buildings. Background Art

[0002] During the construction of the main structure of a high-rise building, a ground pump is usually used for vertical transportation and pouring of concrete. The laying length of the ground pump pipeline is long, and the internal structure of the building is complex. The ground pump pipeline will inevitably turn corners and cross the floor slab. During the concrete pumping process, the pipeline will produce severe vibration and settlement. When the vibration amplitude and settlement exceed 32mm, the pump pipe connection may be broken, causing damage. The traditional method of supporting the pump pipe is to make a fixed support and fix the pipe to the wall column structure, but this method is easily affected by the shaking of the pump pipe and has a poor fixing effect. Therefore, it is necessary to use a pipeline vibration reduction support to take corresponding vibration reduction and anti-settlement measures for the pump pipe to improve the safety of ground pump pouring.

[0003] The pipeline vibration reduction support is a fixed structure, and its structure is as disclosed in the pumping concrete pump pipe fixing vibration reduction device of the authorization announcement number CN217762388U. When in use, the vibration reduction device is provided with a fixing plate, a high-strength vibration reduction spring, a fixing plate under the pump pipe, a connecting bolt and an adjusting spring, so as to achieve the fixing and vibration reduction of the pump pipe during use, thereby ensuring the service life of the pump pipe; However, when the above device is used to reduce the vibration and fix the pump pipe, there are still problems such as:

[0004] 1. Since the spring itself is a buffer and has elastic force, only using high-strength damping springs and adjustment springs for vibration reduction will easily lead to increased vibration force of the pump tube, but will not directly play a role in vibration reduction, thereby reducing the service life of the pump tube;

[0005] 2. The above-mentioned vibration reduction device only has a buffering effect, but cannot effectively absorb the energy generated by the vibration of the pump pipe, resulting in poor vibration reduction effect and failure to effectively fix the pump pipe;

[0006] Therefore, the utility model proposes a vibration reduction support for a ground pump pipeline in a high-rise building to solve the problems existing in the above-mentioned prior art. Utility Model Content

DETAILED DESCRIPTION

[0037] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0038] Example 1: Please refer to Figure 1-6 , the utility model provides a technical solution:

[0039] A vibration-damping support for a ground pump pipeline in a high-rise building, comprising:

[0040] Pump tube 1;

[0041] The vibration reduction mechanism 2 is arranged on the surface of the pump pipe 1 and includes a concrete pier 21, a hoop 22 and a steel plate 24;

[0042] The concrete pier 21 is arranged at the lower end of the surface of the pump pipe 1, and a rubber block 214 is fixedly connected to the top of the concrete pier 21;

[0043] The hoop 22 is arranged on both sides of the top of the concrete pier 21, and a rubber pad 23 is fixedly connected to the inner surface of the hoop 22;

[0044] The steel plate 24 is arranged on one side of the concrete pier 21, and a vibration damping cylinder 25 is fixedly connected to one side of the steel plate 24, a vibration damping rod 26 is slidably connected to the inner wall of the vibration damping cylinder 25, one end of the vibration damping rod 26 is fixedly connected to one side of the concrete pier 21, and the inner wall of the vibration damping cylinder 25 and the opposite end of the vibration damping rod 26 are filled with liquid asphalt, the steel plate 24 and the opposite side of the concrete pier 21 are fixedly connected with a spring 27, the steel plate 24 and the opposite side of the concrete pier 21 are respectively fixedly connected with an elastic pad 28 and an elastic steel block 29, and the shape of the elastic steel block 29 is wavy, rollers 216 are fixedly connected to the bottom of the concrete pier 21 around, a slide rail 217 is provided at the bottom of the concrete pier 21, the surface of the roller 216 is rollingly connected to the inner side of the slide rail 217, and the surface of the vibration damping cylinder 25 is fixedly connected with an electric heating sleeve 210;

[0045] Specifically, when in use, the vertical pump pipe 1 at the shear wall position is fixed by a clamp, one side of the clamp is provided with the same components as the one side of the steel plate 24 (such as a vibration damping cylinder 25 and a vibration damping rod 26, etc.), and the vertical pump pipe 1 passing through the floor slab pipeline adopts an angle steel frame, a clamp and the same components as the one side of the steel plate 24 to fix the pump pipe 1 on the floor slab;

[0046] The steel plate 24 is fixed to the corresponding structural wall by bolts, and the slide rail 217 is fixed to the corresponding ground by bolts;

[0047] When it is necessary to transport concrete to a high-rise building, the pump pipe 1 is assembled with the ground pump. The pump pipe 1 is assembled with the pump pipe 1 for a certain length. The pump pipe 1 is placed between the rubber block 214 and the rubber pad 23. The ground pump is started to make the pump pipe 1 transport the concrete. The vibration generated by the pump pipe 1 in the process of transporting the concrete is transmitted to the concrete pier 21. The roller 216 and the slide rail 217 convert the rigid connection of the pump pipe 1 into a sliding connection, thereby reducing the noise and vibration generated by the pump pipe 1 during operation. Since the liquid asphalt has viscosity and fluidity, the liquid asphalt, the vibration-damping cylinder 25, the vibration-damping rod 26 and the spring 27 absorb the vibration force of the concrete pier 21. The wavy elastic steel block 29 and the elastic pad 28 absorb the vibration force of the concrete pier 21, thereby neutralizing the vibration generated by the pump pipe 1 during operation, thereby avoiding damage to the pump pipe 1 caused by failure to eliminate the vibration during operation. The shock-absorbing mechanism is installed at the corresponding position by bolts, which is convenient to disassemble and assemble and can be repeatedly used.

[0048] Example 2: Figure 3 , Figure 5 and Figure 6As shown, a fixing frame 211 is also clamped on the outer wall of the clamp 22, and the surfaces of both ends of the fixing frame 211 are clamped in the inner wall of the concrete pier 21, and a screw 213 is threadedly connected to the top of the concrete pier 21, and the top of the screw 213 penetrates and extends out of the inside of the fixing frame 211, and the bottom end of the screw 213 and the inner wall of the fixing frame 211 are fixedly connected with a magnetic ring 215, and the two magnetic rings 215 attract each other with opposite poles, and a blocking block 212 is fixedly connected to the top of the concrete pier 21;

[0049] Specifically, when in use, the clamp 22 is placed on the pump pipe 1, so that the clamp 22 abuts against the blocking block 212, the rubber pad 23 abuts against the pump pipe 1, and the fixing frame 211 is pushed down so that the fixing frame 211 is clamped on the outside of the clamp 22, and the end of the fixing frame 211 extends into the concrete pier 21, and the screw 213 is turned to pass through the fixing frame 211 and threadedly connected to the concrete pier 21, so that the magnetic ring 215 on the screw 213 abuts against the magnetic ring 215 on the fixing frame 211, so that the pump pipe 1 is stably installed between the clamp 22 and the concrete pier 21 to avoid shaking under the grouting pressure.

[0050] When the utility model discloses a high-rise building ground pump pipeline vibration reduction support, the following aspects should be paid attention to:

[0051] First, assemble the pump pipe 1 with the ground pump. Assemble the pump pipe 1 and the pump pipe 1 to a certain length. Place the pump pipe 1 on the rubber block 214. Place the clamp 22 on the pump pipe 1 so that the clamp 22 contacts the blocking block 212 and the rubber pad 23 contacts the pump pipe 1. Push the fixing frame 211 downward so that the fixing frame 211 is clamped in the clamp 22 and the concrete pier 21. Turn the screw 213 so that it passes through the fixing frame 211 and is threaded in the concrete pier 21. Make the magnetic ring 215 on the screw 213 contact the magnetic ring 215 on the fixing frame 211. Stably install the pump pipe 1 between the clamp 22 and the concrete pier 21. Start the ground pump so that the pump pipe 1 can transport concrete. The vibration generated in the process of conveying concrete is transmitted to the concrete pier 21. The roller 216 and the slide rail 217 convert the rigid connection of the pump pipe 1 into a sliding connection, thereby reducing the noise and rigid vibration generated by the pump pipe 1 during operation. Since the liquid asphalt has viscosity and fluidity, the liquid asphalt, the vibration-damping cylinder 25, the vibration-damping rod 26 and the spring 27 cooperate to absorb the vibration force of the concrete pier 21. The wavy elastic steel block 29 and the elastic pad 28 absorb the vibration force of the concrete pier 21, thereby neutralizing the vibration generated by the pump pipe 1 during operation, avoiding damage to the pump pipe 1 caused by failure to eliminate the vibration during operation. The shock-absorbing mechanism is installed at the corresponding position by bolts, which is convenient for disassembly and assembly and can be repeatedly used.

[0052] It should be noted that the angle steel frame, clamp, pump pipe 1, magnetic ring 215 and electric heating sleeve 210 in the above description are all relatively mature devices in existing technology applications. The specific models can be selected according to actual needs. At the same time, the electric heating sleeve 210 can be powered by a built-in power supply or by AC power. The specific power supply method is selected according to the situation and will not be elaborated here.

Moreover, the terms "include", "comprise" or any other variants thereof are intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or device.
