Description

[Detailed explanation of the idea] [Purpose of invention] (Industrial application field) This invention relates to a gap retainer.

(Prior Art) Conventionally, gratings have been used as covers for side gutters, and the method of laying them is to close the gap between them and the adjacent gratings.

However, if the grating installation takes a long time, the following problems arise.

The grating is designed in consideration of its dimensional error.
The standard dimensions are approximately 995mm for 1m, and the gap that comes out at the end of the installation is large.

Since the grating cannot absorb the amount of elongation due to thermal expansion, the grating panels warp up against each other.

Furthermore, even if gratings are laid with a slight gap between them, if the length of the gratings is long, the following problem will occur.

When a vehicle passes over the grating, the braking action causes the grating to move and close the gaps between the gratings in a chain reaction.

Then, somewhere the navel wrinkles and a very large gap appears. When a vehicle passes by, the braking action causes the grating panel to climb onto the adjacent panel, causing an accident.

(Problems to be Solved by the Invention) Therefore, the present invention provides a gap holder for gutter gratings that eliminates the above-mentioned drawbacks and does not cause any accidents.

[Structure of the idea]

(Means for Solving the Problems) Hereinafter, an embodiment of this invention will be described with reference to the drawings. It is made of an elastic material and has a holder 3 attached to the upper or lower part by being sandwiched therebetween.

The specific structure of this holder 3 is that two plate-like members 3a and 3b are integrated with a connecting member 3c at their ends, and a grating 1 is inserted between them.
A groove 3d that fits into the main member 2 is formed.

This holder 3 can be attached to the upper end of the main member 2 (see Fig. 3) or the lower end (see Fig. 1). In the former case, two plate-like members 3a, One of the connecting members 3b is short and the connecting member 3c is formed thin.

In addition, two plate-like members 3a, which constitute the holder 3,
The shape of 3b is not limited to that shown in the drawings, and for example, an elastic body may be formed by bending a linear or plate-shaped material to form a member having a constant thickness.

[Effect of idea]

According to this idea, the material of the holder is an elastic material such as rubber and can absorb the amount of thermal expansion of the grating.
The grating can be installed using the normal method, easily maintaining the gap, and even if the braking force is applied to close the gap due to vehicle traffic, once the external force is removed, the grating will be pushed back to the specified position, which is extremely beneficial as there is no risk of accidents. It has a certain effect.
