Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention relates to a construction device for concrete construction capable of continuously performing concrete leveling, leveling and finishing of a building to be constructed.

[0002]

[Prior Art]

 Concrete construction work for a building consists of a driving process in which concrete pumped from a concrete mixer truck is placed on the floor surface, and a leveling process in which the level of the placed concrete is set to a predetermined height. It is carried out through a finishing process that makes the concrete surface smooth.

Conventionally, concrete has been driven by the above-mentioned method, but recently, a driving machine is arranged on the floor so that it can be swung and moved freely, and a concrete pumped by a pump is driven. A method of driving with a tip hose has also been developed.

Next, the leveling process is a work in which concrete is driven and then the surface of the concrete is flattened to a predetermined height by using a ruler, and a plasterer has performed based on his experience, intuition and skill. However, in recent years, in order to save labor in leveling work, we installed pedestals on both sides of the concrete pouring place, installed movable beams that can run between these pedestals, and moved the leveled parts along the movable beams to the movable beams. An automatic leveling machine has been proposed, which is mounted as much as possible to level the surface of concrete to a specified level.

Further, the finishing process is carried out by a plasterer with a gold trowel, or a finishing self-propelled robot is installed on the concrete surface after leveling, and the concrete surface is continuously formed by rotation and running of the iron. Is a smooth surface.

In addition to the above work, there is work for removing breathing water. Excess water floats up on the concrete surface (breathing phenomenon) after a short time after the concrete is driven in, but if this water is not drawn, the finishing work cannot be done by pressing directly. For this reason, plasterers remove this water with a sponge or a piece of cloth so that they can finish it as soon as possible.

[0007]

[Problems to be solved by the device]

 By the way, if each process of conventional concrete construction is performed manually, not only the work efficiency is poor, but also heavy labor is required and it is difficult to secure labor personnel.

Further, the conventional apparatus that mechanically performs each process has a problem that the equipment cost is high because there is no relation independently and there is no shared portion.

Therefore, in order to solve the above-mentioned conventional problems, the present invention mechanically performs each step of concrete construction and systematizes these mechanisms into one to improve the work efficiency. It is an object of the present invention to provide a construction device for concrete work that can significantly reduce the equipment cost by sharing the temporary part.

[0010]

[Means for Solving the Problems]

 In order to solve the above-mentioned problems, the present invention installs a required number of moving beams between rails provided on both sides of a concrete driving portion so that the movable beams can be individually moved along the rails on the concrete driving portion. The moving beam is equipped with a concrete driving machine, a concrete leveling machine, and a concrete finishing machine. By moving each moving beam, concrete can be driven, leveled and finished using a common rail. This is the structure adopted.

[0011]

[Action]

 For the concrete driving part, the concrete is driven by traveling along the rail of one moving beam and the rotation of the driving machine, and then the other moving beam is driven along the rail and along this moving beam. The concrete leveling machine is moved back and forth so that the placed concrete surface is leveled on a horizontal surface of a predetermined level.

Thereafter, another moving beam is run along the rail, and the concrete finisher is moved along the moving beam to finish the smoothed concrete surface smoothly.
