Description of the Related Art Conventionally, as a formwork device for a reinforced concrete structure, a formwork device made of a metal foam or a wooden formwork as shown in FIG. 5 has been generally used. However, such a conventional mold apparatus has the following problems. When assembling a formwork, if the formwork to be assembled is of a relatively short span, the work tends to be complicated and misalignment may occur. At the time of assembling and disassembling the formwork, a worker trips over the formwork material and falls down, or a limb is pinched between the formwork materials, resulting in a dangerous working environment. Many workers and transporting machines are required for loading and transporting the formwork material, and the manufacturing cost is accordingly high. The reinforced concrete structure to be manufactured requires a formwork for each of the straight part and the curved part, and it is necessary to assemble at least two types of formwork, which increases the cost.

構成することができる（図２参照）。DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Preferred embodiments of the present invention will be described below with reference to the drawings. As shown in FIG. 4, the reinforced concrete structure manufactured by the formwork device according to the present invention is used, for example, for a pair of running path base surfaces 40, 40, etc. of a linear motor car. Here, referring to FIG.
In the drawings, reference numeral 1 denotes a mold having a substantially inverted concave cross section. The plurality of molds 1 are arranged substantially in parallel at equal intervals in the width direction. Inside the mold 1, support rollers 2 which are movable in the longitudinal direction and are supported at least at both ends. 1
There is a pair. Further, reference numeral 3 denotes a form setting device. As shown in FIG. 3, the form setting device includes a form setting member 4 laid in a width direction over a plurality of forms 1. It is composed of a pair of support members 5 and 5 that support the form setting member 4 at both ends. As shown in FIG. 3, the form setting member 4 includes a set rod 6 that straddles the form 1 in the width direction and a mold that is loosely fitted to the set rod 6 and is movable in the longitudinal direction. It has positioning members 7,7. Here, two pairs of the mold positioning members 7 are prepared, so that the width between both the molds 1 and 1 can be fixed by the mold positioning members 7. Further, the mold positioning members 7 include the molds 1 and 1.
Width adjusting members 8 are provided so that the width between them can be finely adjusted. Further, a formwork mounting member 9 is interposed between the formwork positioning member 7 and the formwork 1, and the formwork 1 is fixed to the formwork setting member 4 by the formwork mounting member 9. The mold mounting member 9 is usually constructed by attaching an electromagnet below the mold positioning member 7. Positioning pieces 10 are provided below the form positioning member 7 to be locked to the side surfaces of the form 1. The positioning piece 10 prevents the mold frame 1 from being slightly displaced. As shown in FIG. 3, the support member 5 is provided with a movement adjusting member 14 that enables the supporting set rod 6 itself to move in the width direction. By the operation of the movement adjusting member 14, a formwork can be installed at a curved portion, and a curved reinforced concrete structure can be manufactured. The operation of the present invention will be described above. First, as shown in FIG. 1, the width between the molds 1 is adjusted, and the molds 1 are fixed by the mold setting device 3. Next, weir plates (not shown) are attached to both ends in the longitudinal direction, and the inside of the mold 1 is closed. Further, as understood from FIG. 3, it is assumed that the space between the lower end portion of the mold 1 and the base surface 13 in the mold is closed by the closing member 11. Here, the configuration of the closing member 11 is not limited at all, but in this embodiment, a hose member formed of a flexible member such as rubber is used. Here, it is assumed that the mold attaching member (electromagnet) 9 attached below the mold positioning member 7 is operated, and the mold 1 is fixed to the mold setting device 3 by its magnetic force.
In the present embodiment, an electromagnet is used as the form-mounting member 9. However, the present invention is not limited to the electromagnet, and any mounting means such as a screw or a bolt may be used as long as it can be mounted. Absent. In the above, predetermined reinforcing bars are arranged in the form 1 and the concrete 12 is filled. After curing and solidification for a certain period of time, the width adjusting member 8 provided on the mold positioning member 7 is operated to widen the width between the molds 1 and 1 and to remove the mold. Then, after the manufactured reinforced concrete structure is separated from the formwork 1, the power supply of the electromagnet as the formwork mounting member 9 is cut off to eliminate its magnetic force. As a result, the mold mounting member 9 is detached from the mold 1, and the molds 1... Are placed on the support rollers 2. From this state, each mold 1 is moved in the longitudinal direction. After moving the molds 1 to a predetermined position, the mold setting device 3 may be attached to the molds 1... Again to form a predetermined mold device. Therefore, the subsequent procedure is the same as the procedure described above. By the way, as shown in FIG. 2, in order to form a reinforced concrete structure to be manufactured having a certain curve, it is conceivable to previously mount and fix the molds 1. In that case, as understood from FIG. 2, in the longitudinal direction of the mold 1, the mold setting device 3 may be installed at a reduced interval. That is, when installing the form setting device 3 with a reduced interval, the curved form can be easily formed by operating the form positioning member 7 or the like to shift the form 1 to one side as a whole. (See FIG. 2).
