Description

[Detailed Description of the Invention] The present invention relates to a concrete pouring device used at civil engineering or construction sites.

Conventionally, at concrete pouring sites, each time, a
Build a scaffold to transport concrete through pipes, fix the pipe to the scaffold, connect a flexible hose to the end of the pipe, and then have the worker hold the hose in their hands while changing its direction. Concrete was being poured in the required locations.

However, with this method, it takes time to assemble scaffolding to secure the pipe each time it is poured, and in addition, workers have to securely support the hose with their hands when pouring concrete. As a result, work efficiency was poor and improvements were desired.

In order to solve this problem, various manual concrete pouring devices have been proposed in which a support frame is attached to the pedestal so that it can rotate freely, and a ready-mixed concrete transport pipe is supported by the support frame. It became. A conventional example of this type of driving device is a driving device disclosed in Japanese Patent Laid-Open No. 56-46061.

As shown in FIGS. 5 and 6, in this pouring device, a support frame 4 is horizontally rotatably attached to a support arm 2 supported by a plurality of support legs 1 via a swivel bearing 3. The transport pipe 5 is supported by the arm 2 and the support frame 4, and an overhang frame 6 is provided on the side opposite to the transport pipe support side of the support frame 4, and a counterweight 7 is attached to the support frame 6. It is designed to balance the

By the way, when pouring concrete using a concrete pouring device, the flexible hose connected to the transport pipe is bent according to the distance of the pouring location, and the discharge port is moved back and forth to pour concrete. If the height of the transport pipe is not high, the flexible hose will easily touch the ground and become immobile, making it impossible to pour concrete over a wide area and resulting in poor operability.

In addition, if the installation area of the pedestal consisting of the support leg 1 and the support arm 2 is narrow, it is difficult to obtain good stability.
If the flexible hose connected to the transport pipe is pulled too hard, the pedestal may fall, which is dangerous.

When considering the concrete pouring equipment shown in Fig. 5 from this perspective, assembling the support leg 1 and support arm 2 looks extremely simple in the drawing, but when it comes to the installation structure, it is actually not that easy, and there are many The structure is complicated, requiring appropriate reinforcement such as the use of steel, and is difficult to assemble, disassemble, and move. Note that if the lower part of the support leg 1 is embedded in the ground or has a fixed structure fixed to another structure, the installation area will be small;
Although stability is not impaired even if the structure of the pedestal part is simplified, it takes time and effort to fix the support legs 1, and it is not easy to move them.

The object of the present invention is to provide a concrete pouring device whose pedestal part is easy to assemble and move.

In order to achieve the above object, the present invention has a rectangular parallelepiped structure base with casters at the bottom, an outrigger at the tip for ground stabilization, and a horizontal mounting bracket at each almost vertical corner of the base.
