Description

Technical Field

[0001] The utility model relates to the technical field of concrete construction, in particular to a fixing device for a super high-rise concrete pumping pipeline. Background Technique

[0002] At present, the pumps used in concrete construction are fixed by fixing devices. During the process of conveying concrete, due to the large vibration of the pump pipes, there is a problem of axial vibration of the concrete pumping pipeline. At the same time, due to the high vibration frequency, it is not easy to reinforce, which greatly reduces the service life of the pumping pipeline.

[0003] Especially for super high-rise construction, the fixation of the concrete pumping pipeline is a key technical task. When the concrete pumping height exceeds 100 meters, the high-rise pumping pipeline should be fixed firmly to avoid damage caused by shaking. Otherwise, the pipe clamp near the outlet of the concrete pumping pipeline is often pulled apart, causing the concrete pump to be impacted and displaced, and dragged and deformed, seriously affecting the concrete pumping. The main reason for this phenomenon is that the concrete pumping pipeline moves due to the friction of the concrete.

[0004] Specifically, during the concrete pouring process, the prior art most commonly uses scaffolding for fixation, or directly fixes the pumping pipeline with concrete. The following are the disadvantages:

[0005] 1. When using scaffolding for fixation, during the concrete pumping process, the pumping pipeline generates vibration loads on the formwork support system and the concrete cast-in-place slab, which is likely to cause the stability of the formwork support to decrease and lead to formwork support collapse accidents. Using wooden blocks to plug at the floor slab is likely to cause cracks in the floor slab around the reserved holes, resulting in the risk of leakage; in addition, the pump pipe shakes greatly during concrete transportation, which to a certain extent reduces the pumping efficiency and increases the hidden dangers of pipe blockage and pipe explosion during concrete transportation;

[0006] 2. When directly fixing with concrete, not only is the project volume large and not green and environmentally friendly, but also during the concrete transportation, due to the large vibration of the pumping pipeline, the service life of the pumping pipeline is greatly reduced. Content of the Utility Model

[0007] The purpose of the utility model is to provide a fixing device for a super high-rise concrete pumping pipeline, which has a simple structure, is convenient to install, and has a good fixing effect.

[0008] To solve the above technical problems, an embodiment of the utility model provides a fixing device for a super high-rise concrete pumping pipeline, which includes a concrete wall arranged on at least one side of the pump pipe, a clamp for fixing the pump pipe, and a connecting member connecting the clamp and the concrete wall. At least one anchor bar is arranged in the concrete wall, and the anchor bar is bolted or welded to the connecting member. A buried steel plate is arranged in the concrete wall, and the anchor bar is welded to the buried steel plate.

[0009] Among them, the anchor bars are T-shaped anchor bars or hook-shaped anchor bars.

[0010] Among them, multiple said shaped anchor bars are connected to the embedded steel plate at equal intervals.

[0011] Among them, the connecting piece is an H-shaped steel connecting piece or a square pipe steel connecting piece.

[0012] Among them, it further includes a head steel plate arranged between the clamp and the connecting piece, and the head steel plate is bolted or welded to the clamp and the connecting piece.

[0013] Among them, it further includes an anti-rust paint layer arranged on the surfaces of the clamp and the connecting piece.

[0014] Among them, it further includes a rubber pad arranged inside the clamp for contacting the pump pipe.

[0015] Among them, the clamp is a U-shaped clamp or a circular clamp.

[0016] The ultra-high-rise concrete pumping pipeline fixing device provided by the embodiment of the present invention has the following advantages compared with the prior art:

[0017] The ultra-high-rise concrete pumping pipeline fixing device provided by the embodiment of the present invention includes a concrete wall on at least one side of the pump pipe, a clamp for fixing the pump pipe, and a connecting piece connecting the clamp and the concrete wall. By arranging a concrete wall on at least one side of the pump pipe, then fixing the pump pipe with a clamp, and finally connecting the clamp and the concrete wall with a connecting piece, the reinforcement effect on the pump pipe is better. When transporting concrete, it can effectively overcome the wear of the pump pipe caused by axial vibration, greatly improve the service life of the pump pipe, and effectively solve the problem of fixing the ultra-high-rise concrete pumping pipeline.

Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] In a specific implementation manner, the ultra-high-rise concrete pumping pipeline fixing device includes a concrete wall 8 provided on at least one side of the pump pipe 7, a clamp for fixing the pump pipe 7, and a connecting member connecting the clamp and the concrete wall 8.

[0025] By arranging the concrete wall 8 on at least one side of the pump pipe 7, then fixing the pump pipe 7 with a clamp, and finally connecting the clamp and the concrete wall 8 with a connecting member, the reinforcement effect on the pump pipe 7 is better. When conveying concrete, it can effectively overcome the wear of the pump pipe 7 caused by axial vibration, greatly improving the service life of the pump pipe 7 and effectively solving the problem of fixing the ultra-high-rise concrete pumping pipeline.

[0026] In order to further improve the connection strength, in one embodiment, the ultra-high-rise concrete pumping pipeline fixing device further includes at least one anchor bar 1 arranged in the concrete wall 8, and the anchor bar 1 is bolt-connected or welded to the connecting member.

[0027] By arranging the anchor bar 1, on the one hand, the structural strength of the concrete wall 8 is increased, and on the other hand, the arrangement of the anchor bar 1 facilitates the connection of the connecting member and can provide a connection point for the connecting member.

[0028] In this application, the structure, shape, quantity, and size of the anchor bar 1 are not limited.

[0029] Furthermore, in order to improve the convenience of connection and the structural strength, in one embodiment, the ultra-high-rise concrete pumping pipeline fixing device further includes an embedded steel plate 2 arranged in the concrete wall 8, and the anchor bar 1 is welded to the embedded steel plate 2.

[0030] By arranging embedded steel plates 2 in the concrete wall 8, welding the anchor bars 1 to the embedded steel plates 2, and connecting the [relevant part] to the connecting member by bolts or welding, the structural strength within the wall 8 can be enhanced.

[0031] This application does not limit various parameters of the anchor bars 1. To improve the strength of the entire structure, in one embodiment, the anchor bars 1 are T-shaped anchor bars 1 or hook-shaped anchor bars 1, or other shapes. In this way, the connection strength with the concrete is increased, which is beneficial to improving the fixing effect on the pump pipe 7.

[0032] Preferably, multiple [type of] anchor bars 1 are connected to the embedded steel plate 2 at equal intervals.

[0033] This application does not limit the dimensions, etc. of the connecting member. To improve the connection stability, the connecting member is an H-shaped steel 3 connecting member or a square pipe steel connecting member, or a connecting member with other structures.

[0034] To further facilitate connection and transmission of pressure and convenient installation and connection, in one embodiment, the high-rise concrete pumping pipeline fixing device further includes a head plate 4 arranged between the clamp and the connecting member, and the head plate 4 is bolted or welded to the clamp and the connecting member.

[0035] Through the head plate 4, the installation and connection of the clamp and the connecting member can be facilitated, and the connection efficiency is improved.

[0036] This application does not limit the thickness and dimensions, etc. of the head plate 4.

[0037] To further prevent the equipment from rusting and other damages during use, in one embodiment, to solve the above technical problems, in one embodiment, the high-rise concrete pumping pipeline fixing device further includes an anti-rust paint layer provided on the surfaces of the clamp and the connecting member.

[0038] This application does not limit the thickness and material of the anti-rust paint layer.

[0039] To further reduce the vibration of the pump pipe 7 and reduce equipment damage, in one embodiment, the high-rise concrete pumping pipeline fixing device further includes a rubber pad 5 arranged inside the clamp for contacting the pump pipe 7.

[0040] This application includes but is not limited to using the rubber pad 5 to perform shock absorption operations on the clamp and the pump pipe 7.

[0041] This application does not limit the dimensions, quantity, shape, etc. of the clamp, and the clamp is a U-shaped clamp 6 or a circular clamp, or other shapes.

[0042] This application does not limit the specific size and data of the concrete wall 8 and the spacing between the pump pipes 7. The concrete wall 8 can be directly set on the same side of the pump pipe 7, or on both sides, or directly face to face. However, for the convenience of installation, a colloid setting can also be performed.

[0043] In one embodiment, the super high-rise concrete pumping pipe fixing device fixes the fixing support to the concrete wall through the embedded steel plate, fixes it together with the fixing support, and then fixes the pumping pipe to the fixing support using a U-shaped clamp. The specific operation steps are as follows:

[0044] 1. First, make embedded parts according to the concrete pumping pipeline fixing plan, weld anchor bars to embedded steel plates to form embedded parts, and then bury embedded parts at corresponding positions on the concrete wall according to the pipeline direction. The area where embedded parts are placed will be determined based on the review results of the design institute to determine whether to use reinforced steel bars for reinforcement;

[0045] 2. The fixed support is composed of H-shaped steel and head steel plate. The head steel plate is welded to the H-shaped steel, and then the H-shaped steel is welded to the embedded parts. Before welding, the welding position of the H-shaped steel needs to be located and marked on the embedded steel plate and the head steel plate. During the welding process, attention should be paid to the control of the weld quality.

[0046] 3. The pumping pipe is fixed on each support by two U-shaped clamps. The welding position of the U-shaped clamp is located on the head steel plate and marked. Then, the rubber gasket is put on the pumping pipe and temporarily fixed at the welding position of the U-shaped clamp;

[0047] 4. The U-shaped clamp is made of flat steel. It is welded to the fixed support according to the positioning position. Note that the U-shaped clamp should be tightly fitted with the rubber pad to prevent the rubber pad from falling due to the vibration of the pumping pipe during the concrete transportation process. The rubber pad plays a buffering role between the U-shaped clamp and the pumping pipe, reducing the direct collision and friction between the U-shaped clamp and the pumping pipe.

[0048] 5. After the installation is completed, the entire device should be treated with anti-rust paint and sprayed with anti-rust paint.

[0049] The above steps complete the above-mentioned super-high-rise concrete pumping pipeline fixing device and realize it, solving the original design motivation of the new technical solution.

On the other hand, it improves the safety of the fixing of super-high-rise concrete pumping pipelines and reduces the risk of pipe burst and blockage. It has the following advantages:

[0051] 1. Firmly fixed, with little shaking of the pump tube;

[0052] 2. Rubber pad buffering to improve the service life of the pumping pipeline;

[0053] 3. Easy to install and remove;

[0054] 4. Little impact on the on-site construction operation surface;
