していた。[Problems to be Solved by the Invention] It is difficult to form concrete floating slabs on site on viaducts, in tunnels, or on rigid roadbeds of subways, and it is not possible to shorten the construction period. The factory produced a semi-finished product (form) of the floating slab in advance, that is, prefabricated it with precast concrete, brought it to the site, installed it, and then poured concrete into the form to complete the floating slab. When using such a formwork, it is necessary to make the bottom wall thickness of the formwork thicker in order to bear the load at the time of placing concrete and curing, and if it is thicker, the weight will increase and it will be transported to the site and installed. Work becomes difficult. In addition, when the formwork is supported by the square timber on the roadbed, the roadbed and the bottom wall of the formwork must be leveled without any clearance, and the work efficiency becomes poor. In addition, the spacer 101 must be used,
The work of arranging the spacer 101 was troublesome.
Furthermore, the conventional formwork is the same size as the floating slab and is prefabricated with precast concrete, but it weighs about 15 tons and can be held horizontally when installed on a subway track. Was extremely difficult, and required large-scale equipment to carry it horizontally.

It is an object of the present invention to provide a formwork structure for a floating slab for tracks, which improves the level and facilitates leveling.

In a half-type formwork structure in which a side wall and a bottom wall connecting the lower ends of these side walls are halved to have one side wall, a reinforcing bar is embedded inside the concrete side wall and the bottom wall. ,
As a reinforcing bar embedded in the bottom wall, a truss bar having at least two linear reinforcing bars bent in a wavy shape and fixed by welding or the like is used, and a majority of the truss bar is exposed from the bottom wall. The lower deformed steel bar is fixed to the lower side of the lower reinforcing bar of the reinforcement, and the upper deformed steel bar is fixed to the upper side of the upper reinforcing bar of the truss reinforcement. Further, a plurality of vertically projecting bolts are provided on the bottom wall, and the portions of these bolts projecting below the bottom wall are configured as support legs whose height can be adjusted.

Also, even if it is light, it has sufficient rigidity due to the existence of truss bars and deformed steel bars, the adhesion between the deformed steel bars and concrete is improved, and the reinforcing bars directly exposed on the bottom wall can be fixed directly without using spacers. So
It is not necessary to adjust the position of the spacer.

でき、型枠そのものの軽量化が図れる。As described above, according to the present invention, the reinforcing bars are embedded inside the concrete side wall and the bottom wall, and at least two straight upper and lower reinforcing bars are embedded as the reinforcing bars in the bottom wall. Using a truss reinforcement in which corrugated reinforcing bars are fixed by welding etc., a majority of this truss reinforcement is exposed from the bottom wall, and a grid-shaped lower deformed steel bar is fixed to the underside of the truss reinforcement's lower reinforcement. Since the lattice-shaped upper deformed steel bar is fixed to the upper side of the upper reinforcing bar of the truss, there is no need to dispose a spacer as in the conventional case, and since the formwork is half the size, it can be held sideways. It is easy to handle and workability is improved. By connecting two formwork of the present invention, the upper lattice steel bar of the upper lattice can be directly welded to the upper rebar of the truss, and if concrete is placed in the space where the rebar is placed and cured, The floating slab for tracks can be completed easily. In addition, if a plurality of level adjusting support legs projecting vertically are provided on the bottom wall and the height of the parts of the support legs projecting below the bottom wall is adjustable, the leveling of the formwork can be performed easily. At the same time, it becomes easy to install the formwork on site. In addition, by providing such support legs, the rigidity of the formwork is not increased, so that the bottom wall of the formwork can be thinned in combination with the existence of the lower deformed steel bar. The weight can be reduced.
