Embodiment Construction
[0026] Such as Figure 1 to Figure 3 As shown, a vertical concrete pump pipe shock-absorbing reinforcement structure includes: four vertical rods 1 surrounding the concrete pump pipe, and three reinforcement devices 2 arranged at the lower, middle and upper parts of the four vertical rods 1 . The top of the four poles 1 is provided with a jacking 3, and two square steel 4 are placed on the top of the jacking 3. By adjusting the height of the jacking 3, the four poles 1 are closely connected with the upper and lower floors; the distance between the four poles 1 800mm-1200mm.
[0027] The reinforcement device 2 located in the upper and middle parts includes: four first short steel pipes 21, four second short steel pipes 22; the four first short steel pipes 21 are connected with four vertical poles 1, and the concrete pump pipe 100 is surrounded to form It is closed as a whole; on both sides of the concrete pump pipe 100, two upper and lower second short steel pipes 22 are place...

A damping and reinforcing structure for a vertical concrete pump pipe comprises four vertical rods arranged around the concrete pump pipe in a surrounding mode and three reinforcing devices arranged on the lower portion, the middle portion and the upper portion of the four vertical rods, wherein jacking supports are arranged at the tops of the four vertical rods, two pieces of square steel are placed on the upper portions of the jacking supports, and the four vertical rods are tightly connected with an upper floor slab and a lower floor slab by adjusting the height of the jacking supports. Each of the reinforcing devices located on the upper portion and the middle portion comprises four first short steel tubes and a plurality of second short steel tubes, wherein the four first short steel tubes are connected with the four vertical rods, the concrete pump pipe is enclosed to form a closed integrity, each of the two sides of the concrete pump pipe are provided with two corresponding upper second short steel tubes and two corresponding lower second short steel tubes in a tightly attached mode, the second short steel tubes located on the lower portion are erected on the corresponding first short steel tubes, the second short steel tubes are fixed to the concrete pump pipe through split bolts, and rubber gaskets are placed between the second short steel tubes and the concrete pump pipe. The influence of vibration of the concrete pump pipe on the floor slabs in the pumping process is reduced.
Description
【Technical field】 [0001] The invention belongs to the technical field of building construction, and specifically refers to a vertical concrete pump pipe shock-absorbing reinforcement structure and a construction method thereof. 【Background technique】 [0002] At present, there are more and more super high-rise structures in my country, and vertical pumping of concrete is a difficult point in the construction of the main body of super high-rise structures. During the construction of the main structure, in order to facilitate concrete pumping, a hole is usually reserved in the floor (or the original hole in the structural design is used), and the concrete vertical pump pipe passes through the hole to pump the concrete from the bottom of the structure to the construction floor. [0003] Because the concrete will vibrate greatly during the pumping process (this phenomenon will become more and more obvious as the floor increases), in order to ensure the concrete pumping, the ver...
