Description

[Detailed explanation of the idea] The present invention relates to wet edges.

Conventionally, the wet edges were nailed from above to the upper surfaces of the inner and outer rungs.

However, in the above-mentioned conventional wet edge, since the cross-sectional shape of the deck is vertically long, the nails become loosened over many years of use, making the deck unstable, and the nail heads often cause damage to clothing and human bodies.

In addition, when nailing at the site, the spacing between the decks is not constant, which not only makes it unsightly, but also requires the use of buried wood, etc., to hide each nail head, which takes time and effort. It was necessary.

For this reason, for example, the method disclosed in Japanese Utility Model Application Laid-Open No. 48-75426 has been proposed.

This product can solve the above drawback because the nail head is not exposed on the deck, but if this is applied to a wet edge used outdoors where the wood expands and contracts a lot, the nail hole will become larger due to the expansion and contraction, and the nail will eventually become It has the disadvantage of becoming loose.

In addition, since the horizontal beam consists of two parts, it is difficult to assemble.
In addition, the deck itself becomes cracked or chipped, and in order to replace it, the horizontal beam must be disassembled, making the replacement work troublesome, and the nail heads of the nails that connect the two members are exposed on the deck side. This has the disadvantage that it rusts and becomes unsightly.

The present invention was developed in view of the above-mentioned drawbacks of the conventional technology, and it is possible to assemble it on-site in an attractive manner without exposing the nail heads on the deck or on the top of the crossbeam, which is strong, and in a short time and without the need for labor. The purpose of this invention is to provide a wet edge that allows for easy replacement of the deck.

Next, the present invention will be explained with reference to the accompanying drawings, which are one embodiment.

In the figure, 1 is a wet edge according to the present invention, 2 is a thick outer horizontal crosspiece with a rectangular cross section, and as shown in FIGS. 2 and 3, through holes 3 are formed on the upper surface at a predetermined pitch p. The lower end of the through hole 3 has a large diameter.

Reference numeral 4 denotes an inner horizontal bar with a rectangular cross section and a large thickness, which is equal to the length of the outer horizontal bar 2, and has through holes 5 on its upper surface with the same pitch p as the outer horizontal bar 2 and the same number of through holes 3. The lower end of the through hole 5 has a large diameter.

The outer horizontal bars 2 and the inner horizontal bars 4 are arranged parallel to each other at a predetermined interval and at equal heights in the horizontal direction.

Reference numeral 6 designates a deck, and as shown in FIG. 2, positioning holes 7 and 8 are provided in the lower surface near both ends at a predetermined interval S, and the positioning hole 8 at the inner end extends from the inner end surface 6a to the inner side. The horizontal bar 4 is located at a dimension position of one half of the thickness t.

The deck 6 has a plurality of holes arranged in parallel on the upper surface of the outer horizontal beam 2 and the inner horizontal beam 4, and a plurality of positioning holes 7 and outer horizontal beams 2 provided on the lower surface.
The through hole 3 provided in the inner horizontal beam 4 and the positioning hole 8 are made to coincide with the through hole 5 provided in the inner horizontal beam 4.

Numeral 9 is a wood screw that is inserted and screwed from below into the positioning holes 7 and 8 of the deck 6 and the through hole 3.5 of the outer horizontal crosspiece 2 or the inner horizontal crosspiece 4 that are aligned through the large diameter part. Parallel deck 6
is tightened and fixed to the upper surfaces of the outer horizontal beam 2 and the inner horizontal beam 4.

In this case, the heads of the wood screws 9 are located within the large diameter lower ends of the through holes 3 and 5 and are not visible from the outside.

Further, due to the above fixing, the inner end surface 6a of the deck 6 is flush with the inner side surface of the inner horizontal beam 4.

Reference numeral 10 denotes an outer leg portion, and a cutout groove portion 11 is provided on the upper end surface of the outer leg portion, and the lower surface of the outer horizontal beam 2 is fitted into and supported by the cutout groove portion 11.

Reference numeral 12 denotes an inner leg portion, the upper end surface of which is provided with a stepped notch (not shown), which engages and supports the lower surface of the inner horizontal beam 4. .

The outer leg portion 10 and the inner leg portion 12 are supported by placing their lower ends on a base (not shown).

In the wet edge 1 having the above structure, the inner side crosspiece 4 is attached to a desired outer surface of a house (not shown) by nailing or the like as appropriate.

In this case, the inner leg portion 12 may be omitted by firmly attaching the inner horizontal bar 4 to the receiving bar or the like.

In the above embodiment, the large diameter portions formed at the lower ends of the through holes 3 and 5 provided in the outer horizontal bar 2 and the inner horizontal bar 4 are made into large diameter holes, but the invention is not limited to this. A concave groove is provided in the longitudinal center portion of the lower surfaces of the outer horizontal bar 2 and the inner horizontal bar 4, which connects the lower ends of the through holes 3 or 5 and has a width into which the head of the wood screw 9 can be inserted. It's okay.

As is clear from the above description, according to the present invention, the through holes provided on the upper surfaces of the outer horizontal beam and the inner horizontal beam are aligned with the positioning holes provided on the lower surface of the deck, and the wood screws are screwed in from below. Since it is inserted and screwed on, it can be easily assembled.

In addition, since the through holes of the outer horizontal beam and the inner horizontal beam are provided at a predetermined pitch, the deck can be fastened and fixed at equal intervals in an attractive manner.

Since the wood screws are used to tighten and secure the deck, the deck can be firmly fixed to the outer and inner horizontal beams, and even after many years of use, the nails will not loosen like in the past, and the deck will not be damaged. In addition to being more stable, it is possible to improve the drawbacks of nail heads that can cause damage to clothing and the human body.

Additionally, by loosening the wood screws, the deck can be easily replaced when necessary.

Furthermore, since the horizontal crosspiece is a large, one-piece piece, it has sufficient strength.

Moreover, the head of the wood screw is stored in the large diameter part provided at the bottom of the horizontal frame, so the head of the wood screw is not exposed to the outside, and the wood screws are short and easy to install. Due to the presence of the through hole and the large diameter portion, there is no risk of the horizontal beam breaking when screwing in a wood screw, which has many practical effects.
