Movable building construction device

Abstract

The invention relates to a movable building construction device. The movable building construction device comprises a chute body, a sliding support, a sliding rail, formwork supporting frame units, connecting rods and connecting beams. The sliding support can be rotationally installed in a supporting ring at the lower end of the chute body through the connecting rod at the upper end, the supporting frame unit set composed of the two supporting formwork units can also be rotationally installed in the supporting ring through the connecting rod at the upper end, and the movable building construction device and a tank car can be synchronously pushed along the sliding rail to complete whole-section pouring. The formwork supporting frame units can be flexibly pushed to a working face needing construction through walking wheels and can be stably supported on a foundation object through supporting legs after being assembled. A worker can safely and freely walk and work under a frame body through an I-shaped frame, and the adjacent formwork supporting frame units are positioned through the connecting rods in threaded connection and then fixed into a whole through the horizontal connecting beams, the inclined connecting beams and fixing structures, so that the movable building construction device can be applied and popularized in tunnel and pipe gallery roof formwork supporting with narrow working faces, short construction periods and special positions.

Description

technical field [0001] The invention relates to a movable building construction device. Background technique [0002] At present, the construction process of a tunnel generally includes tunnel excavation, tunnel initial support and concrete pouring. The initial support of tunnels generally uses traditional formwork, but it has the disadvantages of high safety risk, low efficiency, large material consumption, high long-term rental price, and difficulty in guaranteeing the quality of concrete pouring. At the same time, the shelf tube in the traditional formwork frame lacks stability before it is formed as a whole. Workers are at great risk in the process of supporting and dismantling the shelf, and it is difficult to control risks such as falling objects and objects hitting; The quantity is high and the duration is long, which seriously affects other sub-items; the quality of wooden formwork assembly is greatly affected by supervisory factors, and the quality requirements of ...

The initial support of tunnels generally uses traditional formwork, but it has the disadvantages of high safety risks, low efficiency, a large amount of material consumption, high long-term rental prices, and difficulty in guaranteeing the quality of concrete pouring

At the same time, the shelf tube in the traditional formwork frame lacks stability before it is formed as a whole. Workers are at great risk in the process of supporting and dismantling the shelf, and it is difficult to control risks such as falling objects and objects hitting; The quantity is high and the duration is long, which seriously affects other sub-items; the quality of wooden formwork assembly is greatly affected by supervisory factors, and the quality requirements of concrete surface flatness, front line straightness, and adjacent sections are difficult to guarantee; Square wood, formwork and other materials have a low turnover rate and are easily lost and damaged. They need to be constantly updated, and their use costs are high. In addition, the long-term rental costs of shelf tubes, buckles and other components are also expensive

Concrete pouring generally uses automobile pumps, but the layout of automobile pumps is limited by the construction site. Even if the site conditions are suitable for supporting automobile pumps, the amount of concrete poured at one time is limited by the width of the excavated foundation trench. Frequent shifting is required to complete the pour, which also results in longer pour times and higher machinery costs

[0003] It can be seen that in the prior art, different devices are needed in the tunnel initial support stage and concrete pouring stage, but these devices are not suitable for tunnel construction, which will increase construction costs and prolong the construction period. It is urgent to develop a solution for cable tunnels. The construction device for the above-mentioned technical problems in the formwork support of the tunnel and pipe gallery roof with narrow working face, tight construction period and special position
