Description

Technical Field

[0001] The technical field involved in the present invention is specifically a ground pump conduit frame body, a shock absorption device and an implementation method for high-rise buildings. Background Technique

[0002] In recent years, with the increasing height of residential floors in China, the concrete placing boom for the construction of high-rise building floors can no longer meet the on-site construction requirements, and a ground pump must be used for concrete transportation. However, when the ground pump transports concrete, it will cause the pump pipe to move up and down, causing the floor frame to vibrate, resulting in problems such as cracking and displacement of the floor slab quality.

[0003] After searching CN108426101A, a shock absorption device that can offset the impact of the pump pipe on the floor slab solves the problem that the floor slab is prone to fatigue damage under the impact of the pump pipe during the concrete pouring of existing walls, beams, slabs and columns. It includes a rectangular vertical steel plate frame passing through the floor slab hole. A horizontal steel plate frame is fixed on the outer side wall of the rectangular vertical steel plate frame. Expansion bolts connecting to the floor slab are penetrated through the horizontal steel plate frame. Vertical connecting plates corresponding to the side walls one by one are arranged inside the rectangular vertical steel plate frame. And a shock absorption spring connecting the two is arranged between each vertical connecting plate and the inner wall of the corresponding rectangular steel plate frame. Rollers are arranged inside the vertical connecting plates. Greatly alleviates the disturbance of the pump pipe to the floor slab in the horizontal and vertical directions when passing through the floor slab, and the shock absorption effect is greatly improved, thus avoiding the problem of fatigue damage of the middle floor slab and ensuring the construction quality of the floor slab concrete. This technology adopts a spring-type shock absorption design structure. The spring-type shock absorption structure can improve the anti-disturbance effect of the pump pipe, but the extrusion degree of the pump pipe during installation is too large, and resonance is prone to occur during shock absorption on the horizontal plane. Summary of the Invention

[0004] The purpose of the present invention is to solve the deficiencies in the prior art, so a ground pump conduit frame body, a shock absorption device and an implementation method for high-rise buildings are proposed. The entire shock absorption device has a complex shock absorption system with different elastic coefficients, which can eliminate resonance and will not directly radially press on the pump pipe.

[0005] In order to achieve the above purpose, the present invention adopts the following technical solutions:

[0006] A ground pump conduit frame body and a shock absorption device for high-rise buildings, including a pump pipe, a shock absorption mechanism is installed outside the pump pipe. The shock absorption mechanism includes an installation body fixedly sleeved outside the pump pipe. A support body is installed on the floor structure through anchor bolts.

[0007] On the basis of the above embodiments, the following improvements are made. The shock absorption component includes an elastic rubber body with a waist-shaped cross-section and a vacuum cavity inside. A unidirectional through trumpet one and a unidirectional through trumpet two are arranged circumferentially inside the elastic rubber body.

[0008] On the basis of the above embodiments, the following improvements are made. A connection structure one is integrally connected to the inner peripheral surface of the elastic rubber body, and a connection structure two is integrally connected to the outer peripheral surface of the elastic rubber body. The connection structure one and the connection structure two have the same cross-section.

[0009] On the basis of the above embodiments, the following improvements are made. T-shaped connection grooves are provided on the opposite sides of the installation body and the support body. The connection structure one is a flexible connection claw adapted to the T-shaped connection groove.

[0010] On the basis of the above embodiments, the following improvements are made. A steel structure support frame is installed between the upper and lower floor slabs, and a secondary shock absorption structure is installed on the steel structure support frame.

[0011] On the basis of the above embodiments, the following improvements are made. The secondary shock absorption structure includes a fixing body one installed outside the pump pipe and a fixing body two installed on the steel structure support frame. The fixing body one and the fixing body two are connected by a circumferentially distributed spring group and an energy absorption body. The spring elastic coefficients between the springs in the spring group are different.

[0012] On the basis of the above embodiments, the following improvements are made. The energy absorption body includes a rubber body. The horizontal cross-section of the rubber body is a combination formed by sequentially connecting a plurality of honeycomb structures.

[0013] On the basis of the above embodiments, the following improvements are made. The steel structure support frame includes a horizontal rod, a vertical rod, and an inclined support. There are two groups of horizontal rods arranged up and down, and a support secondary rod is arranged on the horizontal rod at the bottom. The support secondary rod is used to install the secondary shock absorption structure.

[0014] Implementation method of the high-rise building ground pump conduit frame and shock absorption device. The implementation steps are as follows:

[0015] A Installation steps

[0016] A1. Insert the pump pipe through the reserved hole in the floor slab of the leading building.

[0017] A2. Fix and install the support body at the reserved hole through anchor bolts. Install the installation body outside the inserted pump pipe, and connect it through the T-shaped connection grooves corresponding to the connection structure one and the connection structure two respectively. By squeezing the elastic rubber body, the waist-shaped structure becomes narrower. Then, respectively and completely insert the flexible connection claws of the connection structure one and the connection structure two into the T-shaped connection grooves. After releasing the external force of the elastic rubber body, when the waist-shaped structure resets, it will pull the flexible connection claws back to the maximum scale.

[0018] A3. Install a steel support frame between the upper and lower floor panels, install a secondary shock-absorbing structure on the steel support frame, and connect the first and second fixed bodies to the pump pipe and the secondary support rod of the steel support frame respectively;

[0019] A4. Install the energy-absorbing body and spring assembly between the first and second fixed bodies;

[0020] B. Shock reduction steps

[0021] When the pump pipe vibrates, the elastic rubber body, spring group and energy-absorbing body form a complex shock-absorbing system with different elastic coefficients to prevent resonance of the pump pipe.

[0022] Compared with the prior art, the present invention has the following beneficial effects:

[0023] 1. A shock-absorbing mechanism is installed at a reserved hole in the floor panel. The mounting body and the supporting body and the shock-absorbing assembly therebetween are utilized so that the mounting body and the supporting body slide relative to each other on a horizontal plane. The elastic rubber body of the shock-absorbing assembly is utilized. Since the cross-section of the elastic rubber body is a waist-shaped structure, the internal one-way through bell mouth 1 and one-way through bell mouth 2 are staggered in distribution to achieve shock absorption and reset effects of the elastic rubber body, thereby avoiding resonance on a horizontal plane. Furthermore, a buffer solution of 1 / 3 to 2 / 3 of the volume can be injected into the vacuum cavity to further eliminate resonance.

[0024] 2. The flexible connecting claws of the connecting structure 1 and the connecting structure 2 are adapted to the corresponding T-shaped connecting grooves for installation. During installation, the waist-shaped structure is narrowed by external pressure to insert the flexible connecting claws into the T-shaped connecting grooves. When the external pressure is released, the flexible connecting claws are pulled outward by the elastic rubber body, so that the T-shaped connecting grooves and the flexible connecting claws are effectively assembled.

[0025] 3. Install a secondary shock-absorbing structure on the steel structure support frame, and use the energy-absorbing body on the secondary shock-absorbing structure and the springs with different elastic coefficients to form a shock-absorbing system that eliminates the resonance effect, thereby effectively reducing the resonance phenomenon.
