Problems solved by technology

The main problems of the ground pump concrete delivery technology are as follows: 1. The pump pipe of the ground pump does not move much. Generally, the pipe can only cover 5~8 square meters at a time. Large-area concrete pouring requires multiple installations and dismantling of the moving pump pipe, which is labor-intensive. ;, After the pump pipe of the ground pump is connected to the floor, the horizontal pump pipe needs to be raised on the formwork and steel bar surface of the floor to be poured to transport the concrete to the pouring surface, and the horizontal pump pipe is usually lifted by a steel pipe support frame or a tire for direct support on formwork or reinforcement
When pumping concrete, the impact force generated disturbs the formwork support system, steel skeleton and poured concrete, which affects construction safety and formwork installation quality, and weakens the gripping force between steel bars and concrete. One of the reasons for the cracks; ground pump concrete is not as convenient and flexible as automobile pump concrete pouring, because the automobile pump swings larger, the concrete pouring area is wider at one time, and will not disturb the formwork and steel bars, but the automobile pump conveys height and amplitude restricted

Embodiment Construction

[0023] Such as figure 1 , figure 2 As shown, the pump pipe of the high-rise building of the present invention is suspended at a long distance and the construction technology of swinging concrete is poured, and the technology includes the following construction steps:

[0024] (1) Install the pump pipe 2 through the floor panel: when the floor formwork 5 is installed, reserve the reserved port 3 for the pump pipe 2 through the floor panel according to the position of the pump tube 2 through the floor panel in the pump tube layout diagram, and the pump tube through the floor panel 2. Use the reserved ground anchors to fix in four directions. The height of the protruding floor is generally 150mm plus the thickness of the plate, which is convenient for the installation of the horizontal pump pipe 6. The reserved opening 3 of the floor template 5 extends to the upper side of the floor template 5 to be poured.

[0025] (2) Install the horizontal pump pipe 6 on the upper side of t...

Abstract

The invention discloses pit pump long-distance-suspended pump pipe swinging concreting construction technology for high-rise buildings, and relates to building construction technology. The technology comprises the following construction steps of: 1, installing a pump line passing through a floorboard; 2, installing a horizontal pump pipe, wherein the front end of the horizontal pump pipe is connected to the pump pipe passing through the floorboard while the rear end of the horizontal pump pipe is connected to a working face movable pump pipe, the horizontal pump pipe is supported by a shake-removing support device, and the pipe joint of the horizontal pump pipe is sleeved with a stiffening sleeve; 3, installing the working face movable pump pipe, wherein a 360-degree rotational movable joint I is connected between the working face movable pump pipe and the horizontal pump pipe, and the pipe joint of the working face movable pump pipe is also sleeved with a joint stiffening sleeve; 4, concreting, wherein concrete is poured to floorboard templates through the pump pipe passing through the floorboard, the horizontal pump pipe and the working face movable pump pipe. According to the technology provided by the invention, disturbance of impact force of the pump pipe to reinforcing bars, templates and poured concrete can be eliminated in a concrete pumping process, and large area of concrete can be poured at one time.

Description

technical field [0001] The invention relates to a building construction technology, in particular to a construction technology for long-distance suspension and swinging pouring of ground pump pipes in high-rise buildings. Background technique [0002] In the current concrete construction of high-rise buildings, ground pump concrete delivery technology has been widely used, especially in the floor concrete construction of high-rise and super high-rise buildings, ground pump concrete delivery is an indispensable technology. The main problems of the ground pump concrete delivery technology are as follows: 1. The pump pipe of the ground pump does not move much. Generally, the pipe can only cover 5~8 square meters at a time. Large-area concrete pouring requires multiple installations and dismantling of the moving pump pipe, which is labor-intensive. ;, After the pump pipe of the ground pump is connected to the floor, the horizontal pump pipe needs to be raised on the formwork and...
