Description

  The present invention relates to a concrete floor structure such as a parking lot, a terrace, and a pouch formed of a precast concrete plate (PC concrete plate).

  In general, concrete parking lots, terraces, porches, etc. are made of cast-in-place concrete.

  However, in the case of using cast-in-place concrete, leveling, rebar arrangement, formwork, concrete placement, curing, etc. are required, and not only the work period and cost are increased, but also there is a problem of lack of homogeneity.

  The present invention is a concrete floor structure in which a plurality of rectangular PC concrete plates are laid on the ground, each corner portion of each PC concrete plate is supported by a base, and drainage grooves are formed between the PC concrete plates.

  And each said corner part juxtaposed in the intersection of the said drainage groove, and each said corner part juxtaposed in the edge part of the said drainage groove are each supported by a common base, and each said common base is in the said drainage groove. The interposing ruler portion is provided integrally, and the width of the drainage groove is set by the interposition of the interposition ruler portion.

  The insertion ruler portion can set the width of the drainage groove uniformly, and at the same time, can regulate the both sides of the corners of each PC concrete plate with the common base insertion ruler portion arranged at the intersection.

  As a suitable example, rectangular PC concrete plates are laid in vertical and horizontal alignment on the ground, and drainage grooves that intersect in the vertical and horizontal (cross shape) are formed between the PC concrete plates.

  And by setting the interposition ruler portion integrally provided on each common base disposed at the intersection and end of the drainage groove, the width and street of the drainage groove in the vertical direction and the horizontal direction are set uniformly. Further, both sides of the corner part of the PC concrete plate are regulated on both sides of the common base interposition ruler arranged at the intersection, and the laying position is set.

  The above-described insertion ruler can easily and quickly lay the plate. Also, rain water and car wash water can be introduced into the drainage groove, and the brake effect of the vehicle tire is achieved at the edge of each plate defining the drainage groove, which is safe.

  Each PC concrete plate is floated and supported by the base to form a gap between each PC concrete plate and the ground and to communicate with the drainage groove. The rainwater and the car wash water are passed from the drainage groove to the inside of the gap. Drain the water to improve drainage.

  In addition, the formation of the gap eliminates the interference between the bottom surface of the PC concrete plate and the ground, provides stable support at the four corners, prevents rattling, and uses a common base when laying the PC concrete plates together. Level setting (planar laying) is very easy.

  The drainage grooves are not filled with anything but empty grooves, or gravel is filled in the drainage grooves. Gravel does not hinder the water permeability of the drainage ditch and is effective in controlling grass, and the gravel filled in the vertical and horizontal drainage ditch enhances the cosmetic effect of the entire concrete floor.

  Further, bricks or tiles can be laid in the drainage grooves. Bricks and tiles are simply laid, and bricks or tiles are not sealed with jointing materials, ensuring water permeability and enhancing the cosmetic effect.

  Further, in addition to the above, a plurality of phosphorescent plate receiving holes that can be opened on the surface of each PC concrete plate are provided, and the phosphorescent discs are built in the respective phosphorescent plate containing holes.

  The light storage panel emits light at many points on the concrete floor surface at night, and not only enhances aesthetics, but also exhibits a position display effect such as helping the vehicle to park and assist walking.

The best mode for carrying out the present invention will be described below with reference to FIGS.
A square and large PC concrete plate (precast concrete plate) 1 shown in FIG. 1 and a square and small PC concrete plate 2 shown in FIG. 2 are prepared.
