Description

[Detailed description of the invention] (Field of industrial application) The present invention relates to a mounting structure for a threshold or lintel made of synthetic wood in buildings such as houses.

(Prior art) Conventional sills or lintels are made by processing wood such as cypress, cedar, or hemlock into a predetermined shape at the joint-free parts, and are installed using half posts 2 and studs, as shown in lintel 1 shown in Figure 5. It was to be fixed directly to the 3rd grade with nails 4.

(Problem that the invention aims to solve) However, in the case of the conventional mounting structure, the work is not easy because the nail is driven diagonally into the right angle part formed by the sill or lintel and pillar. I had a problem.

In addition, conventionally used wooden thresholds or lintels tend to warp and deform during storage, and many parts are wasted during processing. Therefore, the inventor of the present invention attempted to solve the problems that wooden lintels or lintels had by forming a sill or lintel using synthetic wood made from an extrusion molded product of a mixed raw material of foamed vinyl chloride resin and wood flour. . Products made of synthetic wood have the advantage of not being deformed due to warping and having no wasted parts, and have a woodgrain appearance.
Furthermore, in terms of processing, it can be nailed, screwed, and cut with a saw, so it resembles wood and has the advantage of being able to be processed and constructed in the same way as wood.

However, even if the synthetic wood is used, the mounting structure is the same as the conventional one, and therefore the installation work is not easy.

The present invention has been made in view of these points, and aims to provide a mounting structure that is easy to install and does not make it difficult to manufacture sills or lintels made of synthetic wood.

(Means for solving the problems) The present invention, which achieves the above-mentioned objects, consists of an extrusion molded product of a mixed raw material of foamed vinyl chloride resin and wood flour,
The top or bottom surface has a groove for fitting and sliding fittings,
In a sill or lintel, which has a substantially T-shaped or substantially inverted T-shaped mounting groove extending inwardly along the longitudinal direction on the opposite surface of the surface, the mounting groove has a substantially T-shaped or substantially reversed T-shaped mounting groove. This is a mounting structure in which a T-shaped mounting plate is attached and the mounting plate is fixed to a half post or stud.

A detailed explanation will be given below, mainly using a lintel as an example, with reference to the accompanying drawings.

FIG. 1 is a partial perspective view, FIG. 2 is a front view for explaining the mounting structure of the lintel, and FIG. 3 is a partial perspective view of the lintel. The lintel 5 is made of an extruded product made of a mixed raw material of foamed vinyl chloride resin and wood flour, and its shape has a groove 6 on the lower surface for fitting and sliding fittings such as shoji, and an approximately inverted T-shape on the upper surface. The mounting groove 7 has a shape that is enlarged on the inside. And Kamoi 5
The surface has a wood grain pattern due to scratches with the inner surface of the die of the extrusion molding machine, and is indistinguishable from wood. The mixing ratio of wood flour is preferably 10 to 60% of the total weight. And the mounting groove 7 of the lintel 5
A substantially inverted T-shaped metal mounting plate 8 is slidably attached to the mounting plate 8, and the mounting plate 8 is attached to a semi-post 9, using bolts, nails, adhesive, or a combination thereof.
They are each fixed to the studs 10 for installation.

FIG. 4 is a partial perspective view of the threshold 11.
1 has a fitting/sliding groove 12 on the upper surface and a mounting groove 13 on the lower surface, and is mounted using the same mounting structure as the lintel.

(Operations and Effects) The mounting structure according to the present invention is such that a sill or lintel made of synthetic wood formed by extrusion molding is installed in a substantially T-shaped or inverted T-shaped mounting groove formed on the sill or lintel. A substantially inverted T-shaped mounting plate is attached, and the mounting plate is fixed to a half-post or the like with nails or the like. Therefore, nails or bolts are driven into the mounting plate and half-posts at right angles, making the installation work easier, and since the mounting plate can slide within the mounting groove, it is not affected by the position of the studs, etc. Furthermore, since the mounting plate is installed in the mounting groove of the sill or lintel perpendicular to the longitudinal direction, it also has the effect of preventing deformation of the sill or lintel. Furthermore, since it is formed into a sill or lintel shape by extrusion molding, post-processing etc. are not required and manufacturing is not complicated. Moreover, since the threshold or lintel is made of a molded product of a mixed raw material of foamed vinyl chloride resin and wood flour, the following effects are achieved. In other words, the wood flour mixture has the effect of making the extruded material, such as a sill, easily cut with a saw in the same way as pure wood. Therefore, the length of the sill etc. can be easily adjusted at the construction site, which has the effect of widening the range of application of this mounting structure.
