Description

[Detailed description of the invention] This invention makes it possible to form openings in buildings simply, quickly, and accurately by combining and connecting the inner frame, middle frame, and outer frame. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Regarding an opening frame device for a building, one embodiment of the present invention will be described below with reference to the drawings, taking as an example the case where the present invention is applied as an opening frame device for a door opening.

1 and 2, a building opening frame device (hereinafter referred to as device) 1 of the present invention includes an inner frame 2, a middle frame 3, and an outer frame 5.

The inner frame body 2 is manufactured by extrusion molding a light metal such as aluminum, and includes a pair of panel support pieces 9, 9 that support the inner sides of the end portions 6, 7 of the wall panels P1, P2 that are arranged in parallel to each other. The intermediate portions of the panels are connected by a connecting piece 10, and external locking protrusions 11, 11 are protruded from the inner surfaces of both panel supporting pieces 9, 9 and slightly away from the tips thereof, and both panel supporting pieces 9, 9 are provided with opposing protruding protrusions 11, On the inner surfaces of the pieces 9, 9 and on the back side of the joint piece 10, inner locking protrusions 12, 12 are provided protruding from and facing each other in proximity to the joint piece 10, and the inner locking protrusions 12, 12 and Inner locking grooves 13, 13 are formed between the fitting piece 10. Note that the inner locking protrusions 12, 12 may be provided on the distal end side of the joint piece 10.

The middle frame body 3 has contact pieces 17, 17 that abut against the outer surfaces of the panel support pieces 9, 9 on both longitudinal edges of a cover piece 16 that covers the tip opening 15 of the inner frame body 2, so that the middle frame body 3 has a U-shape. It is formed to reinforce the inner frame 2 and form a stable base for attaching the outer frame 5. In addition, the inner locking grooves 13, 13 and the outer locking grooves 20, 20 formed between the outer locking protrusions 11, 11 and the cover piece 16 are provided with the inner locking grooves 13, 13, as the inner frame body 2 is erected. A locking portion 22 of a fixture 21, for example as shown in FIG.

The outer frame body 5 includes the end surfaces 2 of both wall panels P1 and P2.
3, 25 and the base plate 27 that abuts the cover piece 16 of the middle frame body 3, protrudes slightly laterally, and has a door stop 26 in the center of its longitudinal direction. Its tip is wall panel P1,
Contact portions 29, 29 are provided to contact the outer surface of P2.

The inner frame 2 is erected in alignment with the reference line marked on the floor surface, and the middle frame 3 is fitted into the inner frame 2 so as to cover the opening 15 at its tip.
When the inner frame body 2 is erected, as shown in FIG. 3, an F-shaped fixing fitting 21 is used in which the fixing piece 30 has locking parts 22, 22, which are rising pieces 22a, 22a. The lower end portions of the inner frame body 2 and the middle frame body 3 are fixed to the floor surface using the above-mentioned method, and in this case, the inner locking grooves 13, 13 and the outer locking grooves 20, 20 are utilized. That is, the fixing metal fittings 21 are arranged between both panel support pieces 9, 9 by nailing the fixing pieces 30 to the floor surface, and the locking parts (rising pieces) 22, 22 are attached to the inner locking parts. By fitting into the grooves 13, 13 and the outer locking grooves 20, 20, respectively, and integrating the cover piece 16 of the inner frame body 3, both locking parts 22, 22, and the joint piece 10 using screws. The lower ends of the inner frame body 2 and the middle frame body 3 are fixed to the floor surface. After that, wall panels P1 and P2
After attaching the wall panels P1 and P2 to the inner frame body 2 by applying the inner sides to the contact pieces 17 and fixing them with screws, the outer frame body 5 is attached so that its base plate 27 is attached to the cover piece 16 and the wall. End faces 23 of panels P1 and P2,
25, and insert it so that it is in contact with the board part 27.
When the outer frame body 5 is fixed by nailing them to the end surfaces 23 and 25, the opening frame 32 of the door opening 31 can be formed as shown in FIG.

In addition, 33 in Fig. 2 is a wall covering material such as cloth that is pasted on the wall panel as necessary, and 35
are provided on the surface of the outer frame 5 as necessary,
This is a decorative layer such as a paint layer or decorative sheet material.

As mentioned above, the device of the present invention combines and connects the inner frame, middle frame, and outer frame that can be manufactured in a factory, and as a result, it can efficiently frame openings in buildings with high precision and stable quality. This makes it possible to form

In the device of the present invention, the outer frame body may be formed by providing abutment portions that come into close contact with the outer surface of the wall panel on both sides of the base plate portion that does not have the door stop portion. Furthermore, the device of the present invention can be applied not only to the vertical frame of the opening but also to the horizontal frame. The inner frame body and the middle frame body can be connected to each other by using a fixing member having a locking portion that engages with the inner locking groove and the outer locking groove, as described above.

The device of the present invention can be used not only as an opening frame device for forming door openings as shown in the embodiments, but also for constructing opening frames of buildings in a wide variety of ways.
