法が普及されてきた。(Prior art) In recent years, mobile formwork equipment has been used to save labor and improve efficiency of construction in the construction of various types of culverts for underground passages and mine shafts, elevated structures with similar shapes, and building frames. Construction methods using this have become popular.
この移動型枠工法によるカルバートの施工は、すでに知

進めて行くのである。As is already known, the construction of culverts using this mobile formwork method involves, for example, a mobile inner formwork device in which the entire formwork is mounted on a trolley, and a mobile outer formwork device in which the formwork is equipped with traveling casters. This is done using a formwork device, but first, the inner formwork device is set in a predetermined position, the reinforcing bars of the side walls and ceiling slab are assembled around it, and then the outer formwork device is set. , pour concrete. After the poured concrete has hardened, the formwork is peeled off, the inner and outer traveling formwork devices are moved to the next construction position, and the same operations are repeated to proceed with construction.

い。したがって、前期の施工期間は、従来、短縮するこ
とのできない必須期間と考えられてきた。(Problems to be solved by the invention) In the conventional construction method, it takes two days to set up the inner formwork device.
To assemble reinforcing bars using the device as an assembly table, 4~
It takes about 15 to 20 days for one construction, including 6' days to set up the external formwork equipment, 1 day to pour the concrete, and 7 to 10 days to cure the poured concrete. ing. In this,
The curing period for concrete is particularly time-consuming.
It is the period of time necessary for the concrete to harden sufficiently to withstand the bending stresses created in the slab concrete and sidewall concrete by the weight of the concrete in the ceiling slab section. Unless this period ends, the inner formwork equipment cannot be removed and moved for construction at the next location. Therefore, the construction period of the first stage has traditionally been considered an essential period that cannot be shortened.

定ができるという施工法を案出した。As a result of conducting research to further improve the construction efficiency of this conventional construction method, the present inventor found that only the inner formwork equipment needs to be left in place for a long period of time for curing the concrete, and the outer formwork equipment Focusing on the fact that the inner formwork can be removed after leaving it for a short period of time, for example, 1 to 2 days, the next We devised a construction method that allows for the assembly of reinforcing bars and the setting of external formwork equipment at locations such as
それによって、従来の工法に比べ、施工の期日をほぼ半
減することができ、施工の能率化、省力化と経済性の向
上とが大巾に図れることになったのである。As a result, compared to conventional construction methods, the construction period can be cut by almost half, and construction efficiency, labor savings, and economic efficiency can be greatly improved.

である。(Effect of the invention) As explained above, in the culvert construction method of the present invention, concrete for the culvert is poured by setting an inner formwork device and an outer formwork device that are movable, and then After moving the outer formwork device to the next construction site with the frame device left in place, and using this outer formwork device to suspend the reinforcing bars that have already been assembled at the construction site, remove the remaining inner formwork. The system is characterized by moving the equipment to the construction site, carrying it in, and pouring concrete, so during the period when the poured concrete is curing, the outer formwork can be moved to the next construction site, set up, and rebar installed. Therefore, it takes 15 to 20 days for one installation.
It is possible to reduce the amount of work required in one day by almost half from 7 to 10 days, and the construction period can be drastically reduced, resulting in economical construction.Moreover, the formwork equipment can be manufactured easily and inexpensively. It also has many advantages, such as being easy to work with.
