JPS60324Y2 - Assembly type road panel - Google Patents

Description

[Detailed Description of the Invention] The present invention relates to a road panel that is lightweight and easy to assemble.

For example, at a railway crossing where heavy vehicles pass through with heavy traffic, crossing boards that can withstand heavy loads are installed between the rails.

However, narrow roads, railway crossings with weight restrictions,
For bridges such as farm roads, panels that can withstand relatively light loads are often sufficient, but in the case of railroad crossings and bridges that use concrete sleepers, only the ends of the panels are supported, so they themselves are not strong enough. It is necessary to withstand sufficient load.

Conventionally, this type of road panel has been troublesome to construct, and there has been a demand for panels that are lightweight and easy to construct.

The present invention provides a road panel that is lightweight and has excellent construction workability, mechanical strength, etc., without the above-mentioned drawbacks.

An embodiment of the present invention will be explained based on the drawings. Fig. 1 is a perspective view of the panel after assembly, Fig. 2 is a cross-sectional view taken along the line ■-■ of Fig. 1, and Fig. 3 is a cross-sectional view of the panel after assembly. 1, the panel is constructed by combining a square upper block 1 made of synthetic resin, a lower block 2 also square, and a reinforcing beam 3 made of copper.

The upper block and the lower block have a mirror-image symmetrical shape, and each block is provided with three parallel concave grooves 4 parallel to the lower block 2, as shown in FIG. ing.

The upper block 1 is also provided with a groove on its opposite surface.

The reinforcing beam material 3 is fitted into these opposing grooves.

In this embodiment, a square steel pipe is used as the reinforcing girder 3, but as shown in FIG. When using this girder material, the upper block 1 and the lower block 2 have a lattice-like groove consisting of parallel grooves and grooves perpendicular to the parallel grooves. will be established.

In addition to square steel pipes, the steel reinforcing girder 3 is made of H-shaped steel, molded grooves,
Structural materials such as channel steel can also be used.

In the rectangular upper and lower blocks, only a groove for inserting the reinforcing girder may be bored, but as in this embodiment, a wide shallow groove 5 is provided, and a deep groove for inserting the reinforcing girder is provided. It is preferable to provide a groove 4.

That is, when the upper and lower blocks are joined together, a cavity is formed, and the weight and stiffness can be reduced with almost no reduction in mechanical strength, thereby saving on the synthetic resin material.

To assemble the panel, the reinforcing beams are fitted into the facing grooves of the blocks, and the upper and lower blocks are appropriately connected in the longitudinal direction of the reinforcing beams 3, and the bolts 7 are inserted through the mounting port holes 6.
This is done by tightening both blocks so that the reinforcing beam material is in close contact with the groove.

Note that the reinforcing girder is configured to be perpendicular to the rail when inserted in parallel.

In this embodiment, the number of the upper and lower blocks is three which are arranged in series in the longitudinal direction, but a plurality of blocks may be arranged in series depending on the strength and length of the reinforcing material.

As shown in Fig. 3, the upper block 1' and lower block 2' located at both ends of the reinforcing girder have grooves that allow the reinforcing girder to protrude from both ends of the panel and prevent it from moving within the groove. 4 is preferably closed at least one end.

As described above, the prefabricated road panel according to the present invention is formed by combining the synthetic resin upper flock, lower block, and reinforcing girder material, so it can be easily assembled by hand using mechanical power at the installation site. can be achieved, resulting in significant savings in construction costs.

In addition, it is lightweight and can maintain sufficient strength, for example, a railroad crossing board using concrete sleepers that is supported at both ends and does not have a fulcrum in the middle;
It is extremely useful as a bridge material for farm roads, a structural material for piers, and as a lining board for sewerage construction sites.

Of course, it can be used as a temporary road structure installed on general poor road surfaces.

The reinforcing girder material is housed in a synthetic resin block and is not exposed to the outside, so it does not corrode, is durable, and can be easily assembled, and can be disassembled and miniaturized when removed or stored. It also has excellent features such as being able to replace only that part if it is damaged.
