Abstract

PROBLEM TO BE SOLVED: To improve the workability by laying a plurality of floor slabs with a rectangular plan shape and legs projected out from the bottom surface on the surface of a road passage with adjacent floor slabs being connected with coupling fittings. SOLUTION: For example, when constructing a linear sidewalk in a utility tunnel having a circular cross section, a non-slip raised portion having a long side is placed on an upper surface, a rectangular floor slab 1 with projected legs on a bottom surface is placed o the bottom portion of the utility tunnel by connecting many floor slabs together continuously, and a butted portion of each floor slab 1 is jointed with bolts 9 and a coupling plate 8. In this case, a lower space of the floor slab 1 formed by legs becomes a drain gutter, leak water from the inner surface of the tunnel is drained to the drain gutter through a gap between a side piece of the floor slab 1 and the inner surface of the tunnel. The floor slab 1 is made by hot molding of resin concrete under pressure, and its moisture absorbing coefficient can be reduced thereby preventing the deterioration. Next, when providing a curved sidewalk, a projected piece pre-formed at front and rear sides of the floor slab 1 is diagonally cut, and each floor slab 1 is butted in a stated of curved contact and is connected with a coupling plate 8. By doing this, work can be executed quickly and reliably, and the construction cost can be greatly reduced.

As described above, the sidewalk can be constructed by the work of loading the floorboards and the work of connecting the floorboards, and the floorboards are lightweight. For this reason, a wide work area can be secured, and it is most suitable for constructing a sidewalk in a tunnel such as a narrow underpass. Since legs are provided at the four corners on the lower surface of the floorboard,
A space is formed below the floorboard. Since the space is formed below the floor plate, even if the mounting surface of the floor plate is uneven, it can be stably mounted without being affected by the uneven surface. or,
Since the space formed below the floorboard functions as a drainage channel, it is easy to construct a sidewalk that intersects with a place where low water flows.

来る。When a protruding portion is provided at the front and rear sides of the floorboard, the protruding portion is cut so that the protruding width gradually decreases from one side to the other side of the floorboard. Abut the cut surface against the adjacent floorboard. As a result, it can be continuously connected in a state of being in contact with an adjacent floor plate, and a curved sidewalk can be constructed. The use of a resin concrete floorboard that is heat-molded at a high pressure makes it possible to maintain the initial strength and appearance for a long period of time even when the floorboard has a low water absorption rate and is used in a humid place or a place where it easily comes into contact with water.

の上面は滑りにくくなっている。In the present embodiment shown in FIGS. 1 to 11, the construction of a linear sidewalk and the construction of a curved sidewalk can both be constructed.
The construction of a straight sidewalk and the construction of a curved sidewalk will be described separately. First, the construction of a linear sidewalk will be described. The floorboard 1 is carried into a circular sinusway 10, and the floorboard 1 is placed linearly and continuously along the bottom of the sinusway 10 serving as a passage surface. To go. Adjacent floorboards 1 are connected by attaching a connecting plate 8 to the butted portion with bolts 9. Thus, a straight sidewalk is constructed (see FIG. 1). Bolts 9 for attaching the connection plates 8 are screwed to the nuts 3 near the abutting portions of the floor plates 1. Since the floorboard 1 is placed on the bottom of the curved sinus 10, the legs 2 of the floorboard 1 are placed in contact with the inner surface of the sinus 10,
A space 11 is formed below the floor panel 1. This space 1
1 is a drainage channel. Further, since the leg 2 of the floor plate 1 contacts the bottom of the cave 10, the side portion of the floor plate 1 does not contact the inner surface of the cave 10, so that the side portion of the floor plate 1 and the inner surface of the cave 10 are , A water leaking from the inner surface of the cave 10 through the gap can be drained into the space 11 below the floor plate 1,
It is effective for drainage of water leak in the sinus passage 10. Since the floorboard 1 is a resin concrete product formed by heating at a high pressure, the water absorption rate of the water is very small, the floorboard 1 is very resistant to moisture and moisture in the cave 10, and there is no corrosion or deterioration. Therefore, the strength and appearance can be maintained in the initial state for a long time. The horizontal ridges 5 on the upper surface of the floorboard 1 allow the floorboard 1
The upper surface is not slippery.

とする等、使用状況によって異なる。Next, the construction of a curved sidewalk will be described. The floor panel 1 is placed along the bottom of the curved sinus 10, and the protruding piece 7 of one floor panel 1 is cut so that the front and rear sides of the adjacent floor panel 1 abut easily.
Butts each other in a curved state. Thereafter, the floorboards 1 adjacent to each other are connected to each other by the connecting plate 8 in the same manner as described above to construct a curved sidewalk. (See FIG. 10) When the curve in the cave 10 is steeper, the protruding piece 7 of the floor panel 1 is cut more diagonally, and the adjacent floor panels 1 are joined in a curved contact state. If the cutting of the protruding pieces 7 of one of the floorboards 1 does not allow sufficient abutment between the adjacent floorboards 1,
The protruding pieces 7 of the adjacent floorboards 1 are cut so that the floorboards 1 are securely butted against each other. When only the protruding piece 7 of one floor plate 1 is cut, the bolt 9 for attaching the connecting plate 8 becomes the nut 3 of the two nuts 3 of the floor plate 1 on the side where the protruding piece 7 is cut away from the protruding piece 7 to the back side. Is screwed on. When the protruding pieces 7 of both floorboards 1 are cut, the bolts 9 for attaching the connecting plate 8 are screwed to the nuts 3 that are both separated from the protruding pieces 7 to the back side. When the floorboard 1 is placed in the cave 10, one of the legs 2 of the floorboard 1
When a gap is formed without contacting the bottom of the floor, a rubber plate (not shown) is interposed in the gap to place the floor plate in a stable state. The length of the projecting piece 7 of the floor plate 1 is set to 20 mm in this embodiment, but may be set to 30 mm or 40 mm.
It depends on the situation of use.

The floor plate 1 is continuously placed on the bottom of the sinus passage 10 in the square culvert in the same manner as in the present embodiment, and connected by the connecting plate 8. A space 11 is formed between the lower surface of the floor plate 1 and the bottom surface of the cave 10 by the legs 2 protruding from the lower surface of the floor plate 1.
It becomes drainage of water generated inside. Other symbols, configurations, functions and effects are the same as those in the first embodiment.
