Abstract

PURPOSE: To prevent a floor slab from floating due to rainwater and also prevent joint sand from flowing out due to rainwater in the installation of light floor slabs. CONSTITUTION: Protrusions 6 are provided at adjacent two sides of a light base board 2 and recessions 7 are provided at other two sides to connect adjacent light floor slabs 1, 1 to each other by fitting of the protrusions 6 and the recessions 7 and joining of a connecting material. Since adjacent light floor slabs 1, 1 are connected together, even if the light floor slab itself is light, each of them is prevented from floating due to rainwater and the whole roadbed face is kept as a unit. Since the connecting part is provided with a shiplap structure, the joint sand is prevented from flowing out.

Description

Detailed Description of the Invention

[0001]

The present invention relates to gravel, concrete,
The present invention relates to a construction structure in which a lightweight floor slab is laid on a roadbed such as asphalt.

[0002]

2. Description of the Related Art Conventionally, tile roadbeds have been mainly constructed by wet construction using mortar. However, wet construction requires complicated steps such as groundwork, tile construction and curing and a long construction period. There are drawbacks. Also, especially
Construction of the roadbed surface of a steel-framed pedestrian bridge is required to be lightweight because of its structure, but when tiles are constructed by wet construction, a mortar substrate with a thickness of 50 mm or more is formed on a steel substrate plate. As a result, the tiles will be tiled, resulting in an excessive weight.

A tile unit in which a plurality of tiles are connected has already been used in many fields, and by laying it, tile construction can be easily performed.

[0004]

Among the conventional tile units in which tiles are connected using a connecting sheet, the force for restraining the tile is weak, and a dedicated material for fixing the connecting sheet to the base layer (roadbed). There are drawbacks such as needing. In particular, when the connecting sheet is soft like a fiber sheet, there is a drawback that unless it is firmly adhered to the base layer, the connecting sheet is turned up when passing through the vehicle.

A floor slab in which a plurality of tiles are pasted on a hard substrate such as a concrete flat plate does not have the above-mentioned problems, but since the weight is too large, the handleability is poor, and the above-mentioned problems occur. As such, it is not suitable for roadbed construction of pedestrian bridges. In addition, a floor slab using a concrete flat plate as a substrate has a drawback that a great deal of labor is required for cutting.

[0006] If a lightweight substrate such as a honeycomb structure plate is used, it is lightweight and easy to handle, suitable for construction of footbridges, and easy to cut. However, there is a drawback that it will surface due to such reasons.

[0007] Generally, when performing roadbed construction using such tile units, the joints between the units are sand joints, but since the units are not connected and are independent, There is also the disadvantage that the sand in the joints between the units will flow under the units, and the joints will be washed away.

The present invention solves the above-mentioned conventional problems, and is a construction structure of a lightweight floor slab excellent in workability and lightness, in which the floor slab is not lifted by rainwater and the roadbed surface accuracy is good for a long time. It is an object of the present invention to provide a construction structure for a lightweight floor slab that can be kept at a high level and can prevent the joint sand from flowing away.

[0009]

The construction structure for a lightweight floor slab according to claim 1 is a lightweight floor slab in which a plurality of lightweight floor slabs each having a floor finish on a square lightweight substrate are laid on a roadbed.

The lighter floor slabs adjacent to each other are connected to each other by engaging the concave portions and the convex portions and joining them with a joining material.

The construction structure of the lightweight floor slab of claim 2 is the construction of claim 1, wherein the lightweight substrate is formed by stacking and bonding two honeycomb boards of the same vertical and horizontal dimensions each having a honeycomb structure portion and a plate portion. The convex portions and the concave portions are formed by shifting and overlapping the upper honeycomb boards so that the upper honeycomb boards protrude from the side edges of the lower honeycomb boards on two sides.

Are bonded with the adhesive.

[0013]

In the construction structure of the lightweight floor slab of the present invention, adjacent lightweight floor slabs are engaged with each other by interlocking between the concave portion and the convex portion provided on the side edge of the lightweight substrate, Since the lightweight floor slabs themselves are light in weight because they are joined and joined by the bonding material, the individual lightweight floor slabs do not float up due to rainwater, and the entire roadbed surface is kept integrated.

Further, since the connecting portions of the adjacent lightweight floor slabs are interlocked, it is possible to prevent the joint sand from flowing away.
