Description

[Detailed Description of the Invention] The present invention relates to a fixture for attaching a mat-like drainage material to a wall surface such as a retaining wall or a tunnel.

Generally, for drainage from concrete retaining walls, leaning retaining walls, and back drainage from culvert boxes, tunnels, etc., mat-like drainage materials made of randomly intertwined chemical fibers and natural fibers are used.
Drainage material is used that is made by randomly intersecting fibrous synthetic resin and forming it into a mat shape.

The above-mentioned mat-like drainage material is attached to the walls of retaining walls, culvert boxes, tunnels, etc. using concrete nails or adhesive tape.

However, when using concrete nails, not only is it time-consuming to install, but it can also cause cracks in the concrete wall.
The drawback is that it is extremely difficult to install the device where the mounting wall surface is a hard rock or has uneven surfaces that prevent it from being hit vertically.

In addition, when using adhesive tape, installation is easy, but due to the poor condition of the mounting wall surface and the surface condition of the drainage material, adhesion is difficult and there is a problem that the drainage material easily falls off when peeled off.

The present invention was developed in view of this, and provides a mounting tool that allows mat-like drainage material to be easily and reliably mounted on any mounting wall surface.

Embodiments of the present invention will be described below based on the drawings.

In the figure, A is a fixture integrally molded from synthetic resin.
This fixture A has a mounting part 1 and an insertion part 2.

The mounting portion 1 has an arbitrary outer shape such as a substantially square, circular, polygonal, etc. having a required thickness, and has a horizontal adhesive seating surface 1a on its lower surface, a recess 1b in the center, and a plurality of recesses 1b at appropriate positions on the periphery. holes (or recesses) le, lc... are provided.

By the way, the hole 1c is sometimes omitted or formed by cutting out from the periphery of the mounting portion.

Next, the length of the insertion portion 2 is appropriately determined depending on the thickness of the mat-like drainage material.

It has a columnar shape with a plurality of retaining pieces 2a at appropriate places on its circumferential surface.
, 2a... are provided protrudingly.

By the way, the shape of the insertion part 2 is a columnar shape that is easy to insert, such as a substantially triangular pyramid shape, a substantially conical shape, a cannonball shape, and a polygonal pyramid shape.

Further, in the embodiment, the retaining pieces 2a are provided symmetrically at the required intervals vertically, but depending on the thickness of the mat-like drainage material, one of the retaining pieces 2a may be omitted or they may be disposed in a scattered manner. be.

Therefore, when using the fixture according to the present invention, if a quick-drying adhesive is applied to the adhesive seat surface 1a of the fixture A and the adhesive is placed on the mounting wall surface W at a required interval, the adhesive C will be applied to the mounting part. The concave portion 1b and hole (or notch) lc of No. 1 are also filled and firmly fixed to the mounting wall surface.

Thereafter, when the mat-like drainage material G is pushed in from above the insertion part 2, the insertion part 2 is inserted into the drainage material, and the drainage material can be easily and reliably attached by the retaining piece 2a.

By the way, when the mounting wall surface is wet due to water leakage, an adhesive such as underwater epoxy is used for the above adhesive.Also, the adhesive is applied in advance to the adhesive seat surface of the mounting part, and then the upper surface is It is also possible to attach a removable sticker to the holder.

Therefore, according to the present invention, the structure is simple and can be mass-produced at low cost, and the mat-like drainage material can be easily and reliably attached.

Furthermore, when a hole (or notch) or the like is provided in the attachment part, weight reduction can be achieved and the attachment can be more firmly fixed.

Furthermore, it has the advantage that no skill is required for its installation.
