Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of concrete pouring auxiliary equipment, especially relates to a detachable concrete vertical pump pipe damping device. BACKGROUND

[0002] Concrete pump pipe (referred to as pump pipe) is an important conveying pipeline system commonly used in building construction, widely used in high-rise buildings, bridges, tunnels and other engineering projects. The main function of the pump pipe is to convey concrete through high pressure, to convey concrete from the ground to the construction area, to improve construction efficiency and reduce the workload of manual handling. The pump pipe can be divided into vehicle pump pipe and ground pump pipe, wherein the ground pump pipe is mainly used for vertical and horizontal conveying of concrete. In the construction process, the concrete is pushed by high pressure through the pipeline, and at the same time, due to the rigid characteristics of the pipeline structure, a certain vibration and noise will be generated during the conveying process.

[0003] During the concrete pumping construction process, the vibration problem of the pump pipe is particularly prominent. Because the concrete has a large density and viscosity, the pulsating pressure generated by the flow of concrete during high-pressure conveying can cause the pump pipe to vibrate strongly, especially during vertical conveying, the impact force and vibration force on the pump pipe are more obvious. This vibration not only affects the uniform conveying of concrete, but also may cause fatigue damage of the pump pipe, loosening of the pipeline connection, and in severe cases, may cause "pipe explosion" accidents, posing a hidden danger to the safety of construction personnel. At the same time, the continuous high-frequency vibration will also have adverse effects on the concrete floor and building structure, which may cause local damage or even cracks in the concrete structure, affecting the engineering quality.

[0004] In order to reduce the vibration of the pump pipe, the existing technology generally uses steel pipe scaffold support or other rigid fixing devices to constrain the pump pipe. Although this method can reduce the displacement of the pump pipe to a certain extent, the rigid connection cannot effectively absorb the vibration energy, and the vibration transmission problem still exists. In addition, such traditional fixing methods are often complex to install, occupy construction space, and are not convenient to remove, which is not conducive to the flexible arrangement of the construction site. Some construction units will fill rubber pads and other damping materials between the pump pipe and the support structure to buffer the vibration, but such methods have limited damping effect, and the fixing method is still relatively complicated.

DETAILED DESCRIPTION

[0027] Hereinafter, an embodiment of the detachable concrete vertical pump pipe damping device of the present application will be described with reference to the accompanying drawings.

[0028] The embodiments described herein are specific embodiments of the present application, which are used to illustrate the concept of the present application, and are explanatory and exemplary, and should not be interpreted as limiting the embodiments of the present application and the scope of the present application. In addition to the embodiments described herein, those skilled in the art can also employ other technical solutions that are obvious based on the disclosure of the claims and the specification of the present application, which include technical solutions that make any obvious substitutions and modifications to the embodiments described herein.

[0029] The drawings of the present specification are schematic drawings that assist in illustrating the concept of the present application, and schematically represent the shape of each part and its mutual relationship. Please note that in order to clearly show the structure of each component of the embodiments of the present application, the drawings are not drawn according to the same scale. The same reference numerals are used to represent the same parts.

[0030] During the construction of a building, it is necessary to use a pump pipe to pump concrete to the pouring construction position, and there is a high demand for pumping concrete to high-level construction positions. During this process, the concrete vertical pump pipe needs to pass through the concrete floor (there may be multiple layers according to the construction height). Therefore, the detachable concrete vertical pump pipe damping device of the present application is proposed.

[0031] In combination with Figures 1 to 5 An embodiment of the detachable concrete vertical pump pipe damping device of the present application is described, which comprises:

[0032] A base 1 is fixed to a concrete floor slab by anchors 3. In one embodiment, the anchor 3 includes a U-shaped round steel bar 32 and a nut 31. The U-shaped round steel bar 32 is embedded in the concrete floor slab, and its end passes through the base 1 and is fixed by the nut 31, which is compatible with the end thread. In this case, the U-shaped round steel bar 32 is constructed together with the concrete floor slab, and it can be integrated with the concrete floor slab, which has the advantage of a strong connection. However, the U-shaped round steel bar 32 can only be used once. In another embodiment, the anchor 3 includes a U-shaped round steel bar 32 and a nut 31. The U-shaped round steel bar 32 passes through a PVC sleeve 2 in the concrete floor slab, and its end passes through the base 1 and is fixed by the nut 31, which is compatible with the end thread. In this case, the U-shaped round steel bar 32 can be disassembled and reused after one concrete pumping is completed, saving usage costs.

[0033] In one specific embodiment of a detachable vertical concrete pump pipe vibration damping device, the base 1 is an integral base 1. Both the base 1 and the concrete floor slab have holes for the vertical concrete pump pipe 7 to pass through. The structure of the holes can be square or round, and the size of the holes must be sufficient for the vertical concrete pump pipe to pass through smoothly. It is important to note that with this type of base, it must be positioned above the floor slab and the pump pipe must pass through simultaneously with the vertical concrete pump pipe passing through the floor. In another specific embodiment of the detachable vertical concrete pump pipe vibration damping device, the concrete floor slab has pump pipe holes for the vertical concrete pump pipe 7 to pass through; the base 1 is a split base 1, comprising a first base 1 plate and a second base 1 plate, which are spaced apart on both sides of the pump pipe hole. The construction of the base of this structure does not need to be synchronized with the construction of the vertical concrete pump pipe. After the vertical concrete pump pipe passes through the concrete floor slab, the first base plate 1 and the second base plate 1 can be set above the floor slab and positioned on both sides of the vertical concrete pump pipe. Then, they can be fixed with U-shaped round steel and nuts, which has the advantage of more flexible construction.

[0034] Pump pipe fixing device 5, combined with Figure 4 As shown, the pipe fixing device 5 includes a first holding member 51 and a second holding member 53. Both the first holding member 51 and the second holding member 53 are composed of a horizontal plate 511 and an arc-shaped ring 512 connected to each other; combined with Figure 3 and Figure 5As shown in the drawings, the horizontal plate is substantially rectangular in structure, one side of the horizontal plate is provided with a semicircular notch, the arc-shaped ring is semicircular in structure, and the arc-shaped ring is fixed at the semicircular notch position of the horizontal plate; in order to prevent structural deformation between the arc-shaped ring and the horizontal plate, in a further preferred embodiment, a stiffener 52 is further included, and the stiffener is fixed between the arc-shaped ring and the horizontal plate; the arc-shaped ring is connected by abutting and splicing the first holding member 51 and the second holding member 53 through locking bolts 54; the first holding member 51 and the second holding member 53 form a pump pipe accommodating cavity after splicing, and the concrete vertical pump pipe 7 is arranged in the pump pipe accommodating cavity; it should be noted that the size of the pump pipe accommodating cavity should be large enough, and a certain distance, such as 5-20 mm, should be maintained between the arc-shaped ring and the outer wall of the concrete vertical pump pipe. In order to avoid the concrete vertical pump pipe from falling under the action of gravity, the rubber pad 6 is arranged between the pump pipe fixing device 5 and the concrete vertical pump pipe 7, that is, the position of the concrete vertical pump pipe is maintained by the friction force between the extruded rubber pad and the arc-shaped ring and the outer wall of the concrete vertical pump pipe.

[0035] The damping spring 4 is fixedly connected with the base 1 at the lower end, and is fixedly connected with the horizontal plate at the upper end; the number of the damping spring 4 is at least two, and corresponds to the first holding member 51 and the second holding member 53 respectively; through the arrangement of the damping spring 4, the vibration of the concrete vertical pump pipe is released by the damping spring, so as to avoid the damage of the concrete floor caused by the vibration of the concrete vertical pump pipe.

[0036] The use process of the detachable concrete vertical pump pipe damping device is as follows: the concrete vertical pump pipe is laid at a predetermined floor position, the base is fixed and installed through the U-shaped round steel and the nut (the base, the damping spring and the holding member are connected as a whole in advance), and then the first holding member and the second holding member are connected by the locking bolt; at this time, the rubber pad needs to be arranged between the pump pipe fixing device and the concrete vertical pump pipe. The detachable concrete vertical pump pipe damping device can effectively reduce the vibration of the pump pipe and reduce the fatigue damage. Since the damping spring structure is adopted in the utility model, part of the vibration energy can be absorbed in the process of high-pressure concrete conveying, the impact and vibration amplitude of the pump pipe are reduced, the fatigue damage of the pump pipe caused by long-term vibration is reduced, and the service life of the pump pipe is prolonged. The influence of vibration on the building structure is reduced The traditional rigid fixing mode is easy to transmit the vibration to the concrete floor, which may cause local damage or even cracks of the structure. The double buffering structure of the damping spring and the rubber pad can effectively isolate the influence of pump pipe vibration on the building structure and improve the construction safety.

[0037] The present inventors have found that the detachable concrete vertical pump pipe damping device of the above embodiment has the problem that when the pump pipe is fixed, if the vibration intensity of the pump pipe is too large, the pump pipe is prone to bending at the part of the holding member and the base due to the limited support force provided by the damping spring itself. Therefore, the above embodiment is further improved, and in a preferred embodiment of the detachable concrete vertical pump pipe damping device, the horizontal plate is provided with a hole 55 corresponding to the position of the damping spring 4; and a support rod 8 is further included, the lower end of the support rod 8 is fixedly connected with the base 1, and the upper end of the support rod 8 penetrates through the hole 55. The above support rod penetrates through the horizontal plate of the holding member, and plays a limiting and guiding role for the holding member, so that the pump pipe can only vibrate within a limited range, and the bending of the pump pipe will not cause the concrete to be unable to be poured. In a further preferred embodiment of the detachable concrete vertical pump pipe damping device, the support rod 8 is arranged at the middle part of the damping spring 4, so that the device is more compact.

[0038] The technical features disclosed above are not limited to the combinations disclosed above with other features, and those skilled in the art can also make other combinations between the technical features according to the purpose of the utility model, and the purpose of the utility model shall be used as the criterion.
