Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a concrete pouring device for pouring concrete into formwork, dirt floors, etc. in civil engineering and architectural works.

Conventional technology Conventionally, in concrete pouring work for civil engineering and construction work, a worker holds the tip of a flexible hose to place concrete delivered from a concrete pump truck or the like through a flexible hose to the desired pouring area. The concrete was being poured while moving from place to place.

Problems that the invention aims to solve However, when pouring concrete into formwork or earthen floors that have been treated with reinforcement, flexible hoses that are under pressure of several tens of kilograms/ ^cm2 jump over the reinforcement. This disturbs the reinforcing arrangement, necessitating rework, and the flexible hose cannot be moved easily, requiring many workers to move the tube tip with great difficulty.

For this reason, devices that use boom-equipped concrete pump trucks or tower cranes to place concrete are known, but they limit the conveyance distance, and because the concrete is poured from a high place and placed, the concrete aggregate may separate. This resulted in poor quality, and the falling concrete caused a large impact, making pouring dangerous.

In addition, Japanese Patent Application Laid-open No. 57-71962 proposes a self-propelled slurry discharge machine in which the tip of the delivery pipe is remotely controlled by a hoisting winch, but it requires a motor to operate the hoisting winch, electric power installation, etc. Therefore, it was difficult to easily and reliably place concrete in a predetermined location.

Further, Japanese Patent Application Laid-Open No. 61-87060 proposes a method of placing concrete using a distributor device that runs along a guide rail. However, because the distributor runs with a guide rail sandwiched between rollers, it can only run in a straight line, and the guide rails are arranged in an L-shape, T-shape, etc. to suit the concrete placement site. It was not possible to pour concrete using the concrete, and the work efficiency was poor.

Means for Solving the Problems The present invention was developed in view of the above-mentioned problems.In order to solve the above-mentioned problems, a concrete pouring pipe is provided with bendable side protrusions in the concrete pouring body. In a concrete pouring device that is configured to place concrete in a concrete pouring section, a manual winch is attached to the tip side of the bendable concrete pouring pipe. The wire of a manual winch is fixed to the support side of the concrete pouring pipe so that the tip side of the concrete pouring pipe can be raised and lowered, and the tip of the concrete pouring pipe is bent downward to form a cylindrical tip. Attach an operating handle to the concrete pouring section, and install a frame-type running rail with a channel-shaped rail mounted on the construction framework scaffolding for the concrete pouring body to run on the concrete pouring section, which is prepared for pouring. As the height of L-shape, T
Concrete is laid in a shape such as a letter shape, an E shape, an F shape, a U shape, etc., and wheels rotatably pivoted like casters are inserted into the above-mentioned running rail to make the concrete pouring body for the above-mentioned running. To provide a concrete placing device characterized in that it is mounted along a rail.

Effects According to the present invention, the rail members of the running rail can be simplified, and the running rail for running the concrete pouring body can be easily laid in the concrete pouring part. In addition, the concrete pouring body can run stably on this traveling rail, and a minimum number of workers can easily operate the tube tip and pour concrete one by one into the required formwork or dirt floor area. The tip of the concrete pouring pipe can be manually operated with a manual winch to easily operate the tip, and the tip of the concrete pouring pipe can be easily raised and lowered to place concrete. It can be constructed without requiring expensive equipment costs. Furthermore, in conjunction with the above-mentioned manual winch, the tip of the concrete pouring pipe can be operated using the operating handle, allowing the tip to be placed in a predetermined location, even in areas where pouring is difficult, such as the side frame or handrail chute. Concrete can be placed by pointing the concrete accurately.
