Description

[Detailed description of the invention] "Industrial application field" The present invention relates to a frame door that requires considerable rigidity, such as a swing door, a slide door, and a door capable of both sliding and swinging. .

"Conventional technology" For automatic doors using heavy glass,
In many cases, it is a frame door whose outer periphery is surrounded by a frame. in this case,
The frame is made of steel frame and the outer periphery is covered with stainless steel decorative material. Conventionally, as shown in FIGS. 4 to 8, various manufacturing methods have been adopted. (1)
(1) The upper frame (2) and the lower frame (3) are manufactured in a state in which the outer periphery of the middle bone (4) is covered with a decorative material (5) in advance, and then these vertical, upper and lower frames (1) are manufactured. ) (1), (2) and (3) were assembled at four corners.

More specifically, the vertical frame (1) is made of an inexpensive steel frame material as shown in FIG. 6 and is bent into a concave shape in section, or as shown in FIG. Fitted and welded at an appropriate location (7), and a cylindrical cosmetic material (5) having a concave cross section was fitted in the longitudinal direction in the longitudinal direction and welded (7) or screwed (6) at regular intervals. It is made. Also, as shown in FIG. 8, the upper frame (2) and the lower frame (3) are similarly fitted with a decorative material (5) by fitting a channel material or a square tube material with a middle bone (4). Are welded.

And these vertical frames (1) (1), upper frame (2),
In order to assemble the lower frame (3), as shown in FIG. 5, the vertical frames (1) and (1) are formed by cutting out the assembly holes (8), and the upper frame (2) and the lower frame (3) are formed. ), A part of the middle bone (4) is formed as a protruding handle (9), and the contact portions of the middle bones (4) and (4) are formed while combining these assembling holes (8) and the handle (9). Welding (7)
It is made.

"Problems to be solved by the invention" All conventional frames are assembled after the decorative material (5) is put on the middle bone (4), so that the welding part of the decorative material (5) is not exposed to the outside or exposed. However, it must be done in a place that is not normally seen. Also, when assembling two channel members or the like with the middle bone (4), if the number of welding points is increased, the whole is warped and the frame is not straightened. Therefore, rigidity is not enough to support a large glass door frame, and it is distorted in the plane direction, the shape of the assembling part becomes complicated, and if necessary, an L-shaped reinforcing material (10) , Welding (7) must be performed.

An object of the present invention is to obtain a frame door having sufficient rigidity and easy to assemble.

[Means for Solving the Problems] In the present invention, in a frame door using a frame whose inner bone is covered with a decorative material, each inner bone of a standing frame, an upper frame, and a lower frame is welded in advance to form a frame. The decorative material is covered from both sides of the middle bone and fixed at the seam of the decorative material on the glass insertion groove and the opposite surface, and the fixed portion is closed with a door stop, a door slide prevention plate or a smoke return gasket. It is a frame door characterized by being hidden.

[Operation] A square pipe made of a steel frame material is used as a core of two standing frames, an upper frame, and a lower frame, and is welded in advance to form a four-sided frame. After welding, a decorative material such as a stainless steel plate is covered two by two from the side. Then, the joint portion of the decorative board is welded. Welding points are places that are not normally visible from the outside, such as the glass insertion groove, the upper surface of the upper frame, and the lower surface of the lower frame. If you can't see it from the outside,
It is covered with a door sliding prevention material, smoke return material, etc.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

In FIG. 1, (11) is a knock-out door, and (12) is a sliding door. In addition, these doors (11) and (12)
3) It may be one that can be opened and closed by swinging around (14).

These doors (11) and (12) consist of a four-sided frame (15) and a single glass plate (16).

The four-sided frame (15) includes two standing frames (1) (1), 1
The upper frame (2) and the lower frame (3) consist of steel frames (1), (1), (2) and (3), as shown in FIG. Middle bone of square pipe (4) (4) (4)
(4) is fixed by welding (7) so as to form a square frame (15). Of these bones, those for standing frames (4)
(4) has a substantially square cross section, and the middle frame (4) for the upper frame is welded at appropriate intervals by overlapping two square pipes having a rectangular cross section. 3) is obtained by stacking three rectangular pipes having a rectangular cross section and welding them at appropriate intervals.

Before welding, it is desirable that these intermediate bones (4) be processed in advance before welding, such as a turning support shaft mounting hole (17), a latch mounting hole (18), and a slide mounting hole.

After welding the middle bone (4) as shown in FIG. 3, two pieces of decorative material (5) (5) such as stainless steel are fitted from each side and welded.

For further details, see the decorative panel for door stalls (5a) (5
In a), a concave press-formed plate is split vertically in a symmetrical manner, and is welded to the middle bone (4) at the glass plate insertion groove (19) and the opposite surface.

When the glass (16) is inserted, the glass insertion groove (19) becomes invisible from the outside, but the opposite surface is exposed to the outside, so that a rubber door stop (20) is stuck to hide the welding location. In addition, the decorative panels (5b) and (5c) for the vertical frame on the door sliding side shall be divided by the center of the glass plate insertion groove (19) and the corner of the opposite surface. The welded portion becomes invisible when the glass (16) is put in the same manner as described above, but since the welded portion at the opposite corner is exposed, a door slide prevention plate (21) and a smoke return gasket (22) are attached.

The decorative panels (5d) and (5d) for the upper frame are also formed by dividing the concave shape from the center, and are welded at the glass insertion groove (19) and the upper end surface. Even if the upper end face is exposed, there is no problem in appearance.

One of the lower frame decorative boards (5e) and (5f) has a concave shape divided from the center, and the other (5f) has a U-shape. When the glass (16) is fitted to the middle bone (4) after welding, the glass (16) is inserted from the side of the U-shaped decorative plate (5f), and a decorative U-shaped glass stop rail (5) made of a decorative material is used.
g) with screws (23).

In the above-described embodiment, a square pipe made of a steel material is used as the middle bone (4). However, the present invention is not limited to this. For example, a channel material having a U-shaped cross section may be used.

In the above embodiment, the decorative materials (5a) (5b) (5c) (5d) (5
e) Although a stainless plate is used for (5f) and (5g), the present invention is not limited to this, and plastic, aluminum, flame-retardant wood, paper, and other decorative plates may be attached.

In addition, the glass insertion groove (19) may be made of the middle bone (4).

[Effects of the Invention] The present invention is configured as described above, so that sufficient rigidity of the frame can be obtained, and it is particularly suitable for an automatic frame door with a single glass door.

In addition, since the decorative material is merely covered from both sides of the middle bone, the process of fitting the decorative material into the middle bone is not only easy, but also fixed at the seam of the decorative material in the glass insertion groove and the opposite surface. Therefore, the portion to be fixed is exposed to the outside, so that the fixing workability is excellent and the fixing is reliable.

Furthermore, there is no defect in appearance by hiding seams such as welding of a decorative board with a rubber door stop, a smoke return gasket, a door sliding prevention plate or the like.
