BRIEF DESCRIPTION OF THE DRAWINGS The drawings show one embodiment of the present invention, and the structure will be described with reference to the drawings. (A) shows a wooden grating, (1) shows a horizontally elongated hole (2) of a wooden grating (a). (B) shows an edge frame of wooden grating (a), (3) edge pieces before and after edge frame (b), (4) edge frames on both sides of edge frame (b) (5) is a front and rear receiving piece, (6) is an intermediate front and rear receiving piece, and (7) is a receiving piece on both sides.

[0007] (8) is a joined thin plate for producing a wooden grating (a) (hereinafter simply referred to as a thin plate).
Then, as shown in FIG. 8, several thin and long plates which are ground with lumbers such as larch and pine litter and made to a thickness of about 5 mm are arranged side by side in the width direction as shown in FIG.

Then, as shown in FIG. 7, a plurality of thin plate members (8) are overlapped in a cross type in which the wood fiber directions are alternately arranged vertically and horizontally, and are bonded with a waterproof adhesive to form a laminate.

Then, the laminated plate is appropriately cut to a required size, and the upper plate (1), front and rear edge frame pieces (3), both side edge frame pieces (4), front and rear receiving pieces (5), and an intermediate piece. Of the receiving piece (6) and the receiving pieces (7) on both sides.

Next, the upper plate (1) is formed by arranging a plurality of horizontally long holes (2) at appropriate intervals in the material of the upper plate (1). An end plate (9) having a thickness of about 5 mm is bonded to the exposed upper and lower edges of the material of the front and rear edge frame pieces (3) by a water-resistant adhesive, and the upper and lower edges and both edges of the edge are exposed to the end plate (9). To form front and rear edge frame pieces (3). An end plate (10) having a thickness of about 5 mm is bonded to the exposed upper and lower edges of the material of the edge frame pieces (4) on both sides with a waterproof adhesive, and the upper and lower edges are closed with the end plate (10). Is formed. Each of the front and rear receiving pieces (5), the intermediate receiving piece (6), and the receiving pieces on both sides (7) has a lower end of the material at the lower edge of the exposed wood.
The end plate (11) having a thickness of about mm is bonded with a water-resistant adhesive, and the ends of the ends are closed with the end plate (11) so that the front and rear receiving pieces (5), the intermediate receiving piece (6), and the receiving pieces on both sides are closed. A piece (7) is formed.

Therefore, as shown in FIG. 7, both end surfaces of the edge frame pieces (4) on both sides are adhered to both ends of the facing surface of the front and rear edge frame pieces (3) with a waterproof adhesive. To form

Next, in the lower part of the edge frame (b), the receiving piece (5) is laid in front and back, and the receiving piece (6) is laid in the middle front and rear, and the front and rear receiving pieces (5) and the middle receiving piece are placed in between. The receiving pieces (7) are interposed on both sides between (6) and the intermediate receiving pieces (6), (6), and their joints are bonded with a waterproof adhesive. Thereafter, as shown in FIG. 5, the upper plate (1) is fitted into the upper portion of the edge frame (b), and the front and rear receiving pieces (5), the intermediate receiving piece (6) and the both receiving pieces (7). Put on top,
These joints are bonded with a water-resistant adhesive. Then
Although not shown, a wooden grating (a) is formed by waterproofing the surface with an epoxy resin.

(12) is a U-shaped gutter of the road, (13) is a concrete lid of the gutter (12), and (14) is a gutter (1).
The square of (2) and (15) are the concrete lids of the square (14).

When epoxy resin is waterproofed on the above-mentioned surface, if powder or the like is mixed in the epoxy resin, the surface of the wooden grating becomes rough and the effect of preventing slipping and abrasion is increased. be able to.

The wooden grating described above can be used in place of the concrete gutter of the gutter.

The concrete lid of the box can be constructed and acts in a similar manner to the wooden grating described above.

[0017]

The wooden grating of the present invention has the following advantages.

(1) Since the grating is made of wood, it is good for scenery, light, easy to put on and take off, and easy to handle, and the sound is quiet even when people walk or drive, and the neighborhood is annoying. do not become.

(2) A thin plate having a thickness of about 5 mm that constitutes the grating can be cut off between nodes and scratches on a wooden board, so that the yield is good and the price is low.

(3) Since the thinned lumber can be used after being ground with lumber, it is socially beneficial by effectively utilizing the materials.

(4) Several thin plates having a thickness of about 5 mm are juxtaposed in the width direction and bonded with a water-resistant adhesive to form a thin plate. A laminate is formed by bonding with an adhesive, and the laminate is cut into required dimensions to produce a perforated top plate, an edge frame piece, and a receiving piece. The board is bonded with a water-resistant adhesive, and the perforated top plate, the edge frame piece and the receiving piece are bonded with a combined water-resistant adhesive. Therefore,

(A) Mass production in a factory.

(B) Since the thin plate has a thickness of about 5 mm, the thin plate on the surface is stretched by absorbing rainwater or the like, and has a weak stretching force of drying and shrinking. In addition to the difference in wood fiber direction of the boards due to their cross-type superposition and the adhesive strength of the waterproof adhesive, the above-mentioned expansion and contraction between the boards is stopped, and the end plates with the waterproof adhesive to the exposed kiguchi By closing the end plate and the water-resistant adhesive, the end of the thin plate of the laminate is closed, and the penetration of rainwater or the like from the end of the laminate into the laminate is prevented, and the expansion and contraction of the wooden grating is almost eliminated.

(5) Even if rainwater or the like impinging on the surface of the wooden grating penetrates into the thin plate and the end plate on the surface of the wooden grating, the waterproof adhesive between the thin plates of the laminate and between the laminate and the end plate The rainwater and the like penetrate only the thin plate and the end plate on the surface and do not penetrate the core of the wooden grating. Therefore,

(A) There is no deformation of the wooden grating.

(B) Drying is quick after rain.

(6) The surface is waterproofed with epoxy resin. Therefore,

(A) The epoxy resin soaks into the surface of the wooden grating to harden the surface of the wooden grating,
Since the epoxy resin adheres strongly and does not peel off the epoxy resin, the epoxy resin layer prevents water penetration.

(B) The surface of the wooden grating is not stained by the epoxy resin layer, so that the cleanness of the wooden grating is long-lasting, there is no discoloration or decay, and the wear of the wooden grating is prevented and the durability is high. It is.

(7) It can be easily constructed and easily manufactured at low cost.
