Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a construction rail material used for thresholds, lintels, etc.

[Conventional technology and its problems]

Traditionally, solid wood is used as the railing material for lintels, etc., or laminated wood or laminated wood is used, and if necessary, decorative veneer is pasted, or the surface It was obtained by carving a rail groove of arbitrary depth on the side.

However, due to the nature of the wood itself, solid wood and laminated wood are prone to warping, twisting, sun cracking, etc., and as a result, the decorative veneer tends to peel off or crack at the end of the wood. are doing.

[Means for solving problems and their effects]

In order to solve the above-mentioned problems, the construction rail material according to the present invention uses wood fiberboard as the base material 1, and has at least one rail groove 4 formed in the upper edge corner part parallel to the rail groove 4. A small stepped portion 2 is formed,
A decorative sheet-like material 3 is wrapped and pasted from the surface including the small step portion 2 excluding the rail groove 4 to a part of the back surface including the end portion.

In particular, the construction base material of the present invention uses medium-density fiberboard, that is, non-directional wood fiberboard with a specific gravity of 0.4 to 0.8.

By using such a wood fiberboard, warping, twisting, and other distortions will not occur over time, and the decorative sheet-like material 3 will not have a cut surface 3a.
This prevents it from peeling off or cracking.

[Explanation of Examples]

Embodiments of the present invention will be described below with reference to the drawings.

1 is the equipment, which uses wood fiberboard such as hard fiberboard and medium density fiberboard.

In particular, long fiberboard is advantageous because it has no fiber orientation and is lightweight.

Next, at least one rail groove 4 is formed on the surface of the base material 1. Then, small steps 2, 2 are formed at the upper edge corners of the rail groove 4.

Next, the decorative sheet-like material 3 is rolled up and pasted from the surface of the base material 1 including the small step portion 2 of the rail groove 4 to a part of the back surface including the woody portion. At this time, if the sheet-like material 3 is pasted to the inside of the rail groove 4, the sliding of the door will become poor and construction will be difficult. As the decorative sheet material 3, decorative veneer, foamed PVC sheet, decorative paper, synthetic resin sheet, etc. are used.

The end surface of the base material 1 may be chamfered if necessary.

In this way, the rail material for construction of the present invention is obtained, but in the rail material of the present invention, the cut surface 3a of the sheet-like material 3 is formed at the end of the small step part 2 in the rail groove 4, so that the sheet-like material 3 is It never peels off.

Further, as shown in FIG. 2, a concave track body 5 made of synthetic resin is fitted into the track groove 4 to prevent wear and improve sliding. In this case, the upper end of the concave track body 5 corresponds to the cut surface 3a of the sheet-like article 3, and prevents the hangnail.

As shown in FIG. 4, the concave body rail 5 may be provided with a plurality of protrusions 5a on the outside of its vertical portion for fitting and fixing, or the top of the concave portion may be made wider than the bottom so that the concave body rail 5 can be removed after fitting. may be prevented.

As shown in Fig. 5, a plurality of concave bottom ridges 5b are provided in the concave bottom of the concave rail body 5 in a direction parallel to its length, thereby reducing the contact area with the bottom of the door body and improving sliding properties. You can.

Alternatively, as shown in FIG. 3, a collar 6 facing toward the bottom of the concave rail body 5 is provided at the tip of the vertical part of the concave rail body 5,
The concave rail body 5 is fitted into the rail groove 4. At this time, the collar 6 is provided, and the concave rail body 5 is fitted into the rail groove 4. At this time, by fitting the collar 6 into the recess 2, the cut surface 3 of the decorative sheet-like material 3 inside the recess 2
a is pressed down and will not peel off, and its surface is formed to be a smooth surface except for the recessed portions of the concave track body 5.

[Effects of the present invention] Since a uniform wood fiberboard is used as the base material 1 and the decorative sheet-like material 3 is attached to the surface, the design is improved, and it looks innocent at first glance, and is free from irregularities such as warping and twisting. , durability is improved without the occurrence of sun damage. In particular, by using medium density fiberboard as the wood fiberboard, a particularly suitable building rail material can be obtained.

A small step is formed at the corner of the upper edge of the rail groove in parallel with the rail groove, and the cut surface of the decorative sheet-like material is located at the end of the small step, so it is difficult to handle surfaces that are subject to large external force loads. This prevents the decorative sheet from peeling off and hanging.

Furthermore, if the flange of the concave track body is fitted into the rail groove so as to fit into the small step, the surface will be formed as a smooth surface except for the concave portion of the concave track body, and the corner of the concave end corner will be smooth. This improves durability and design.
