DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an opening frame structure, and more particularly, to an opening frame structure using a precut frame material of an upper frame and a vertical frame having a door stop groove on an inner surface and a casing groove on a side surface.

[0002]

2. Description of the Related Art In mounting an opening frame inside an opening, conventionally, a frame material is processed for each site to mount the opening frame. In this case, after adjusting the width dimension of the frame material according to the wall thickness, a joining process is performed at the abutting portion between the vertical frame and the upper frame, and a door stop member is further fixed to the inner surface. Field work was required.

In recent years, with the spread of industrialized houses (prefabricated houses, 2 × 4 houses), construction using standardized members has been widely performed, and so-called pre-cut frame materials pre-cut at a factory have been used as frame materials. It is becoming. The opening frame structure by the pre-cut frame material is formed by butt-joining a vertical frame and an upper frame in which a door stop groove is formed on an inner surface and a casing groove is formed on a side surface, and a door stop member is fitted into the door stop groove, and is inserted into the casing groove. Is fitted with a casing that can be adjusted according to the wall thickness.

[0004] An example of an opening frame structure using such a precut frame material is disclosed in Japanese Utility Model Publication No. Hei 6-27747. In this open frame structure, a cut (A) having a predetermined height and width is formed in a vertical frame in advance, and a cut (B) having a predetermined height and width is formed in an upper frame in advance. (See FIG. 2 of the publication), when the upper frame and the vertical frame are butt-joined at the site, the α portion is cut at the butt-joint portion so that the casing grooves of the upper frame and the vertical frame communicate with each other. (See FIG. 4 of the same publication).

[0005]

However, in the above-described open frame structure, it is necessary to form cuts of a predetermined size in both the upper frame and the vertical frame, which requires a lot of processing time, and furthermore, it is necessary to form these cuts. If the dimensions do not match each other, it is difficult or impossible to fit the casing at the butt joint, so high processing accuracy is required, and a problem remains in terms of product yield.

[0006]

SUMMARY OF THE INVENTION The present invention has been made to solve the above-mentioned problems of the prior art, and has an upper frame having a door stop groove on an inner surface and a casing groove on a side surface. In the opening frame structure consisting of vertical frames,
Only the same depth as the casing groove over the dimension of the thickness of the outer flange of the other frame material plus the width of the casing groove at the tip of one of the upper or vertical frame material The cutout is formed to form a notch, and the inner surface of one of the frame members formed with the notch and the cut end of the other frame member are butt-joined to join the casing grooves of these frame members to each other. It is characterized by having been communicated in the section.

[0007] The notch formed at the edge of the edge of the one frame material is a pair of notches formed by cutting both sides of the inner flange in the width direction at the edge of the edge of the frame material. It can be.

BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is an exploded perspective view showing an embodiment of an opening frame structure according to the present invention. MDF), a hard fiber board, a particle board, a flake board, an oriented strand board, a stick board, a veneer laminate, a laminated wood, or the like can be provided as a single substrate or as a composite plate in which any laminate is laminated. Decorative paper, decorative impregnated paper, decorative synthetic resin sheet,
A decorative material such as a decorative veneer can be attached.

A door stop groove is formed on the inner surfaces of the upper frame 1 and the vertical frame 2 (only the door stop groove 6 formed on the inner surface of the vertical frame 2 is shown), and the casing grooves 3 are formed on the side surfaces thereof. , 4 are engraved. The casing grooves 3 and 4 are formed on both side surfaces or one side surface of the upper frame 1 and the vertical frame 2 as necessary.

At the end of the vertical frame 2, the width of both sides of the inner flange portion 2a in the width direction of the inner flange portion 2a is extended over the dimension obtained by adding the width of the casing groove 3 to the thickness of the outer flange portion 1b of the upper frame 1. A pair of cutouts 5, 5 are formed by cutting off the same depth dimension as that of FIG. In FIG. 2, a portion shown by a broken line is a cut portion.

The door stop grooves and casing grooves 3 and 4 engraved on the upper frame 1 and the vertical frame 2 and the notch 5 formed at the end of the opening of the vertical frame 2 are formed by a cutting device such as a moulder or tenoner. Pre-cut at the factory using

In this manner, the upper frame 1 in which the door stop groove on the inner surface and the casing groove 3 on the side surface are formed in advance,
An opening frame structure is formed by butt-joining a door stop groove 6 on the inner surface, a casing groove 4 on the side surface, and a notch portion 5 at the edge of the edge to a vertical frame 2 formed in advance. This is performed by joining the edge of the front end of the upper frame 1 to the front end of the upper frame 1 from outside of the vertical frame 2 with a fastener (not shown) such as a nail or a screw. The upper frame 1 and the vertical frame 2 are joined and fixed.

In the obtained open frame structure, as is apparent from FIG. 1, the casing groove 3 on the side surface of the upper frame 1 and the vertical frame 2
And a casing (not shown) connected by butt joint or by cutting the tip to 45 degrees and joining them together in the casing groove 3, 4. Can be fitted into A door stop member (not shown) is fitted into the door stop groove on the inner surface of the upper frame 1 and the vertical frame 2 as is known.

In the embodiment shown in FIGS. 1 and 2, the upper frame 1
No notch is formed, and the inner flange 2a at the edge of the edge of the vertical frame 2 is cut off by a predetermined width and depth to form the notch 5.
However, conversely, the notch may be formed in the upper frame 1 and the notch may not be formed in the vertical frame 2.

That is, as shown in FIG. 3, the inner flange 1a is provided at both ends of the opening of the upper frame 1 with the outer flange 2b of the vertical frame 2.
The thickness of the notch 5 ′. Is equal to the depth of the casing groove 4 over the thickness of the casing groove 4 plus the width of the casing groove 4. 5 'is engraved and fixed at a state where the edge of the vertical frame 2 is joined to the lower surface of the edge of the upper frame 1 at the edge of the edge, whereby an open frame structure is obtained. In FIG. 3, reference numeral 7 denotes a door stop groove formed on the inner surface of the upper frame 1.

[0016]

According to the opening frame structure of the present invention, by forming the cutout portion only on one side of the precut frame material, the casing grooves on the side surfaces can communicate with each other at the butt joint portion, so that the precut operation can be performed. Done easily and quickly.
