[0002] During the concrete pouring construction of the main structure of a building, concrete pumping pipes are often used as concrete delivery facilities to solve the problem of delivering concrete to high-rise buildings. At present, the inter-layer concrete pumping pipes are fixed by setting up a steel pipe frame around the reserved holes in the floor slab. Specifically, short steel pipes are used to cross the concrete pump pipes first, and then long steel pipes and short steel pipe fasteners are used to connect them. The long steel pipes are supported on the floor slab surface, and the bottom of the long steel pipe is fixed with wooden blocks at the contact point with the floor slab. However, using this positioning method, the construction of the steel pipe frame is more troublesome and requires professional personnel to operate; the steel pipe fixing and limiting effect is poor, and when conveying concrete, the pump pipe is easy to shake left and right and cause damage to the floor slab; after the steel pipe frame is erected, during the concrete delivery process, if concrete blocks the pipe, the pipe ruptures, and other pipes need to be inspected and replaced, it is not conducive to rapid dismantling and recovery.

Therefore, during use, the utility model of the floor-penetrating concrete pump pipe limiting and fixing device respectively places the first steel support 1 and the second steel support 2 on both sides of the reserved hole in the floor, fastens the steel base 3 to the floor B by expansion bolts, and raises the two limiting steel plates 5 with semicircular notches to a certain height by steel pipes 4, and uses the two semicircular notches to clamp the concrete pump pipe A, thereby limiting the displacement caused by the shaking of the concrete pump pipe when conveying concrete. The utility model of the floor-penetrating concrete pump pipe limiting and fixing device has a simple structure, good fixing effect, easy disassembly and assembly, and can be reused. It replaces the traditional reinforcement measures of setting up a steel pipe 4 frame, and can effectively solve the problem of the pump pipe passing through the floor causing damage to the floor when conveying concrete, speeding up the construction speed and making the construction more convenient.
