Description

[Detailed Description of the Invention] <Industrial Field of Application and Summary of the Invention> The present invention relates to a frame unit for an opening in a building, and more specifically to a frame unit in which a pair of mullions and their lower frame members are formed of shaped steel materials. , and is composed of upper frame lattice beams, which transmits the vertical load applied to both sides of the opening frame downward, and provides a frame unit for a building opening that is easy to install and has high construction accuracy. It is.

<Prior Art> Conventionally, at an opening in a building, vertical loads were transmitted from the upper floor to the lower part or to the foundation by columns or walls on both sides and magasa or small walls at the top.

<Problem to be solved by the invention> Therefore, there is little freedom in the arrangement and size of openings, and especially when providing continuous openings on the upper and lower floors, it is difficult to transfer the load from the upper floor to the lower floor. It is necessary to increase the cross-section of the above-mentioned members for transmission, narrow the opening itself, and furthermore, add additional supports, waist walls, small walls, etc. to increase the structural strength at the boundary between the openings on the upper and lower floors. Nakatsuta.

Therefore, in order to provide continuous openings between the upper and lower floors, the number of parts increases and construction time is required.

<Means for Solving the Problems> The present invention relates to a frame unit devised in view of the above points, which includes a pair of mullions and an opening fixed to a frame member above and below the mullions and configured in a substantially rectangular shape. A frame unit for a building opening that can transmit the vertical load from the upper floor to the lower floor through the mullions of the frame, in which the pair of mullions are made of lightweight channel steel and the upper frame material is further lowered by using lattice beams. The frame is constructed of channel steel, with the grooves of the mullions facing the indoor side and the outer side facing the inner side so that the extension width is approximately the same as the thickness of the wall to which the outer surface is attached. It is characterized by its extended length.

<Function> The opening frame placed in the opening has an upper frame made of lattice beams and a mullion and lower frame made of lightweight section steel, so it receives the vertical load from the upper floor and does not disturb the lower floor. can be transmitted smoothly. Moreover, in the mullion, the grooves of the lightweight steel section are directed toward the indoor side, and the outer sides thereof extend toward the indoor side, so that the grooves can be used effectively while being attached to the opening.

1, 11, an upper frame member 12 formed integrally with the mullions 11, 11, and a lower frame member 13 fixed to the lower part of the mullions 11, 11, thereby forming a substantially rectangular shape. The mullions 11 and 11 are made of lightweight channel steel, which is a channel material, and the opening side (groove) of this lightweight channel steel is
is formed so that it faces toward the indoor side.

Moreover, the mullioned outer surface 11c that comes into contact with the inner peripheral surface of the building opening has an inner side 11b and an outer side 11.
a, of which the outer side 11a extends further into the room than the inner side 11b,
Its extension width is set to be approximately the same as the thickness of the wall (around the opening) to which it is attached.

The upper frame member 12 is formed of a lattice beam made of steel. That is, this upper frame member plays the role of a so-called magsa that connects the heads of the mullions 11 and 11, and receives the load from the upper floor and transmits the load to the mullions 11, 11 on both sides.

On the other hand, the lower frame member 13, unlike the upper frame member 12, does not have the role of transmitting a load, but is made of lightweight channel steel similar to the mullion 11 in order to hold the mullions 11, 11.

These mullions 11, 11, upper frame member 12, and lower frame member 13 are connected to each other by high tension bolts or welding.

FIG. 2 explains how the opening frame 1 having the above structure is attached to an opening in a building.

The building opening 3 is surrounded by walls 31, 31 made of air-quality panel walls, lightweight aerated concrete walls, etc. on both sides.

In such a state, the inner peripheral surfaces 32, 3 of the opening
2 are placed in contact with the mullioned outer surfaces 11c, 11c of the opening frame 1.

Similarly, in the opening 4, the walls 41, 41
The inner circumferential surfaces 42, 42 of the opening frame 1 are brought into contact with the mullusoidal outer surfaces 11c, 11c. That is, the outer side 11a extending toward the indoor side is fixed to the inner circumferential surface 42. Then, if the opening frame 1 on the upper floor is placed on the opening frame 1 on the lower floor and both are fixed,
A frame unit is constructed that is connected to the building openings 3 and 4 (so-called continuous window state), and the opening frames 1, 1 are attached to the inner peripheral surfaces 32, 32, 42, 42 of the frame unit.
The mullions 11, 11, 11, 11 are arranged in a continuous manner, and the vertical load from the upper floor is applied to the foundation 5 of the lower floor via each mullion 11, 11, 11, 11. information is smoothly communicated to

The abutting parts of the opening frames 1, 1 and the walls 31, 41 arranged in these openings are covered with decorative frames 6, 6 from the outside of the building, and the opening frames 1 on the upper floor and the openings on the lower floor are covered with decorative frames 6, 6. Curtain plate 7 at the border with frame 1
are arranged so that the respective abutting parts and joint surfaces are not exposed on the outer wall surface.

FIG. 3 is a schematic diagram for further explaining the opening frames 1, 1, ie, the frame unit, which are continuously attached to the lower and upper floors.

Mullions 11, 11, 1 of each opening frame 1, 1
1 and 11, an opening provided in the opening 4 of the lower floor is placed above the opening frame 1 provided in the opening 3 of the lower floor in order to smoothly transmit the vertical load from the upper floor of the building to the lower floor. A frame 1 is provided continuously.

Furthermore, as shown in this figure, it is also possible to provide an opening that is continuous at the corner of the building.

Furthermore, although not shown in the drawings, so-called large-span openings with many openings in the wall surface can be easily constructed.

On the other hand, the opening frame 1 is disposed in the upper floor opening 4 in the same manner as described above, and the upper frame member 12 has the same configuration as the upper frame member 12 of the opening frame 1 disposed on the lower floor. In addition, since the lower frame member 13 is installed in close contact with the upper floor panel 9 surface and the outer surface, it is necessary to arrange a material that is taller than the lower frame member 13 of the opening frame 1 placed in the opening 3 of the lower floor. In some cases, it may be set.

The opening frames 1, 1 and the openings 3, 4 are connected to each other by inserting screw nails into pre-drilled mounting holes and nailing them to the floor panels 8, 9, or by tightening them with bolts or the like. Particularly, bolted connections can be easily replaced when the function of the opening is changed due to changes in the occupants or surrounding environment of the building. That is, when changing the opening frame 1 in which the window sash is installed to another opening frame having a bay window with storage, etc., the replacement can be easily carried out by taking out the bolts and tightening them again.

Since 1a has an extension width comparable to the thickness of the wall to which it is extended toward the indoor side and is attached, a mounting allowance for the inner circumferential surface 32 of the opening 3 is obtained, and it can be easily fixed with the mounting bolt v.

FIG. 6 is a sectional view illustrating how the mullions 11 are attached when a wall body 31 made of a wood panel is used.

As explained in FIG. 5, the outer side 11a of the lightweight channel steel constituting the mullion 11 is
Fixation is facilitated by bringing the screw nail n into contact with the inner circumferential surface 32' of the opening 1' and driving the screw nail n from the indoor side of this outer side 11a.

Furthermore, as shown in Figures 5 and 6,
Decorative picture frames 91 and 9 are provided on the indoor side of this opening frame 1.
1 is provided, and decorative frames 6, 6 are attached to the outdoor side, thereby covering the joint surfaces of the walls 31, 31' and the opening frame 1.

Therefore, the space 0 formed by the groove of the mullion 11 and the decorative frame 91 can also be used as a wiring and piping space.

As described above, when the opening frame having the above structure is used, the opening frame constitutes a vertically continuous frame unit, and moreover, the opening frame transmits the vertical load from the upper floor of the building to the lower floor. Since it plays a role as a so-called structural material, it can be easily formed into continuous windows, building corner windows, large span openings, etc. In addition, by attaching window sashes, bay windows with storage, security shutters, etc. to the opening frame in advance, and replacing the opening frame itself as necessary, the function of the opening can adapt to changes in the occupants and the surrounding environment of the building. This makes it possible to provide an extremely multifunctional opening.

Furthermore, the opening frame itself is constructed from lightweight steel and lattice beams, and the grooves of the lightweight steel mullions are directed toward the interior of the room, with the outer sides extending toward the interior, making installation easier. Wiring and piping are very convenient, and since such an opening frame is mass-produced at a factory as a standard product, the efficiency of on-site construction is improved in terms of accuracy.
