Description

[Detailed explanation of the idea] This idea relates to a disused fittings frame with sleeves.

Generally, as shown in Fig. 1, the disused fittings frame with sleeves is
A structure has been used in which a mullion C is provided between the left and right vertical frames A and B, and a door and a shaft part E are arranged on both sides of the mullion C.

The opening in the width direction of the door formed by the right vertical frame B and mullion C, and the opening in the height direction (not shown) formed by the upper and lower door frames Due to the size of the items, the standard width is 800m/
m.

A height of 1,900 m/m has been adopted, and for mullion I, a design height of approximately 55 m/m is required due to the bending of the shaft panel and the encroachment of the door.

The opening in the width direction of the shaft formed by the left vertical frame A and the mullion C is designed so that a general newspaper with a width of about 200 m/m folded in four can be received at the mail slot G provided in the shaft part E. In order to achieve this, at least 300 m/m is required, taking into consideration the bending of the base and shaft panel.

This size will be approximately the same even if a milk container is provided in the shaft portion E that can accommodate three 1/2-pack milk paper cartons side by side.

Therefore, if you add the door width opening of 800 m/m, the mullboard width of 55 m/m, and the shaft side width opening of 300 m/m, the total width opening of the door with sleeves becomes n55 m/m, so this dimension is normally used. 1200m/m is adopted.

As a result, the total opening area of the sleeve door attachment part is 1200rr.
1/m x 1900m/m = 2.28d, and in door shapes such as those with sleeves, the wall that separates one residential unit, etc. from common areas such as hallways and stairs, as specified by 1973 @ Boan 49, has a fireproof structure. , and the total area of the openings in the wall must be less than or equal to 2rIl for a - dwelling unit, etc., which is a drawback in that the standard cannot be met.

The object of this invention is to solve the above-mentioned drawbacks and to provide a disused fittings frame with sleeves that can form a sufficiently wide opening in the width direction for an opening of 2 or less.

To explain an embodiment, FIG. 2 shows a case where the fitting frame of this invention is installed between left and right building walls 1.degree. 2 which are arranged in parallel.

3 is a left vertical frame attached to the left body wall 1, and 4 is a right vertical frame attached to the right body wall 2.

Reference numeral 7 denotes a mullion that stands vertically at one end of the door side upper and lower frames 5 and 5' provided along the extension line of the right body wall 2. On the left side of the mullion 7, there is a door side upper and lower frame. Upper and lower shaft-side frames 6, 6' are provided in a direction bent by an angle of θ with respect to 5, 5'.

On the right side of the mullion 7, a door 8 is rotatably attached to the right vertical frame 4 with a hinge 10, and between the mullion 7 and the left vertical frame 3,
A shaft portion 9 is attached.

In this way, the upper and lower frames 5, 5' on the door side and the upper and lower frames 6 on the sleeve side of the door with sleeves
, 6' are bent at the part of the mullion 7, the opening dimension a in the width direction of the left and right vertical frames 3 and 4 is fully opened [even if it is 1050111/m which is necessary to make 1 area 2- or less , door width direction opening b' = 800m/m with mullion 1
= 55m/m and keeping the dimension 855m/m, the shaft width direction opening C is made into triangles a, b, e
According to the formula of the triangular cosine theorem that defines the relationship between the angle and the angle formed between those two sides, the opening dimension C is smaller than when the shaft portion 9 is directly provided along the opening dimension a of the left and right vertical frames 3 and 4. It can be expanded very easily.

When it is desired to make the dimension of the opening C in the width direction of the shaft side as wide as possible in the above-mentioned embodiment, the position of the mullion 7 is set to 7 and the left body wall 1 with respect to the extension line of the right body wall 2, as shown in FIG. If the mullion 7 is located on the opposite side and the size to be widened is small, the mullion 7 may be located on the same side as the left body wall 1 with respect to the extension line of the right body wall 2, as shown in FIG.

FIG. 5 shows the left and right body walls 1,
This embodiment is applicable when the distance J1m in the perpendicular direction between the door 8 and the shaft portion 9 is larger than the shaft width direction opening C, and shows a case where the door 8 and the shaft portion 9 are arranged at right angles.

FIG. 6 shows another embodiment that is applied when the left and right body walls 1 and 2 are arranged on the same line, and by appropriately selecting the position of the mullion 7, the door width direction opening b' Required dimensions can be given to and the shaft width direction opening C, respectively.

FIG. 7 shows still another embodiment, in which a required length is attached to one of the left and right body walls 1 and 2 arranged on the same line, for example, on the side surface of the left body wall 1 in a direction perpendicular to this. A wing wall 11 is provided, and the tip side wall portion of the wing wall 11 and the right body wall 2
The shaft portion 9 is arranged parallel to the left and right body walls 1 and 2 through the mullion 7 between the front end portion of the door 8 and the door width direction opening b' by bending the door 8 with respect to the shaft portion 9. and the shaft width direction opening C are given the required dimensions.

As is clear from the above explanation, according to this invention, the opening area between the left and right building walls is equal to the area required for a fireproof structure.
Even if the opening size is less than or equal to 1, the opening dimension in the door width direction and the opening dimension in the shaft side width direction can be set to the required dimensions.

For this reason, the dimensions of the shaft of the door with a sleeve on the entrance side are particularly widened, and the dimensions of the mail slot and milk tray installed in this area are widened to make it easier to take out folded newspapers and milk in paper cartons. It can be done.

Furthermore, even if an external force acts simultaneously from the left and right walls toward the fitting frame due to the effects of an earthquake, etc., the external force will not only act to damage the fitting frame, especially the mullioned part, but also cause damage to the fitting frame. This acts as a couple that rotates the frame around the opening, or a component of the external force acts in the direction of pushing the mullioned part out of the opening, reducing the deformation of the fitting frame and allowing the door to open. It can also be expected to have the effect of reducing the negative impact of the fittings frame on the building.
