Description

DETAILED DESCRIPTION OF THE INVENTION The present invention is a traveling caster device KII suitable for use in movable formwork in the construction of retaining walls, culverts, and various other types of concrete.

In the construction of horizontally long concrete structures such as retaining walls, sound walls, and culverts, hand-assembled and hand-cut formwork has generally been used, but in recent years, formwork has been used to streamline construction and save labor. For this purpose, a mobile formwork construction method has been developed in which the entire log-shaped formwork is assembled in one size and is moved to the next construction position and used repeatedly. As means for moving batons in this construction method, there are two methods: lifting and moving the formwork with a crane, and moving the formwork by placing it on a traveling cart or the like.

The method of moving the formwork using a crane not only requires a large space for the installation and movement of the crane, but also increases the crane cost, as well as the cost of assembling and demolishing the formwork. The operation becomes sloppy and requires a high degree of skill.

It is not a good idea either from an economic or technical point of view. In addition, elevated structures such as highways and railways have many drawbacks, such as 1. Since the work is done at high places, there are many restrictions and it is difficult to use cranes.

In the case of the method of running and moving the formwork, the Kr11 frame is placed on a running trolley that supports the entire 11 frame, and many shirts a
? Since the molding machine is equipped with a molding machine to carry out operations such as assembling and demolding the formwork, the carriage is large and heavy, and is also complicated and expensive. Therefore, not only is there little economic advantage, but it also requires space for facilities for running carts.
Particularly in the construction of culverts, there are drawbacks such as the work area becomes narrow and construction efficiency is hindered.

The present invention was made in order to solve the above-mentioned problems in the moving formwork construction method. It is equipped with a traveling wheel and a lifting and tilting adjustment function that allows operations such as assembling and demolding of the formwork. These operations can be performed using extremely simple and inexpensive equipment, and the operation is simple and reliable, and there is no need for a special large space for moving the formwork, making formwork construction economical. The aim is to greatly improve performance and workability.

DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of the present invention will be described with reference to drawings of tubes.
