Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a surface structure that constitutes the roof surface or outer wall surface of a building.

Generally, the above-mentioned surface structure is required to have excellent fire resistance and sound insulation properties.

In addition, indoor wiring has traditionally been regulated to be safe under electrical and fire protection laws and regulations, and in ordinary houses, wiring should be installed in easy-to-see locations such as under the ceiling, under construction materials, and on the sides. In addition, electric wires are strung using insulators in concealed locations that can be inspected, such as in the main building behind the ceiling.

However, in modern buildings with few windows for daylighting, indoor wiring is placed in places where it can be easily destroyed by human disasters, so in the event of a fire, the lights go out immediately after the fire breaks out, not only at night but even during the day. There are problems in which it becomes impossible to evacuate, emergency bells stop ringing, and even microphones don't work, which can lead to accidents that result in loss of life.

By forming a space between the inner and outer layer members, the present invention achieves excellent fire resistance and sound insulation in response to the above-mentioned demands, and by running electrical wiring and piping in the space, electric wires can be placed on the roof. By placing it close to the face plate of a board, etc., it can maintain the energizing function for a longer time than conventional ones in the event of a fire, and it can solve the above-mentioned problems.It also has a large degree of freedom and is relatively easy to install. , aims to provide an inexpensive surface structure for buildings.

That is, the surface structure of a building according to the present invention has a substantially channel-shaped first structure with flanges protruding from both sides of the opening end.
The flange of the receiving member is overlapped with a plate-shaped inner layer member containing a fireproof material and fixed to a supporting member such as a main building, and an open end is attached to the end opposite to the 7 langes of the first mounting member. A substantially channel-shaped second mounting member with flanges protruding from both sides is fitted and fixed, and a plate-shaped outer layer member for sound insulation and sound absorption is attached to the flange of the second mounting part. At least one of the members is a long member perpendicular to the support member, and a face plate is fixed to the end of the second member opposite to the flange.

Embodiments of the present invention will be described below with reference to the drawings.

1 to 3 show an example in which the present invention is applied to a roof.

In FIGS. 1 to 3, (1) is a support member such as a main house made of wood or metal with an approximately C-shaped cross section;
1) A plate-shaped inner layer member (2) made of a layered sound absorbing material (2a) and a fireproof material (2b) is laid on top of the inner layer member (2).
2) Above, the seven flanges (3a) of the first mounting member (3) are superimposed and arranged above the support member (1).

The first mounting member (3) has flanges (3) on both sides of the opening end.
A) has a so-called approximately hat-shaped cross section with a protruding part, and a fixing device (4) such as a nail or a wood screw is inserted into the inner layer member (2) from above the flange (3a) to attach the support member. (1), the first attachment member (3) and the inner layer member (2) are fixed to the support member (1).

A second mounting member (5) is fixed to the outer periphery of the upper end of the support member (1) by spot welding, screwing, or other suitable means. Like the first mounting member (3), the second mounting member (5) has a generally knot-shaped cross section with flanges (5a) protruding from both sides of the opening end. , the height is the first mounting part'! A' (3) & It is a long piece of material that is lower than the supporting part fA'(1'l) and constitutes a rafter.

Both ends of the plate-shaped outer layer member (6) consisting of the second mounting member (=7 langes (5a) upper center sound insulating material force of the J member (5)) are supported and fixed, and the second mounting member (5) is An outer layer member (6) is firmly placed between them, and a space (7) is formed between the inner and outer layer members (2) and (6).
Indoor electrical wiring (8) is routed through the mounting members (5).

In addition, the electrical wiring (8) is as shown in FIG.

(8a) and tighten the inner layer part 1 (2) 4 with the stopper (9).
It may be fixed.

A cut protrusion (5b) is provided on the upper end surface of the second receiving member (5).
are protruded from one side, and roof plates (10) serving as face plates are latched and fixed to these protrusions (5b) for horizontal roofing.

FIG. 4 shows a modification of the first and second mounting members of the present invention,
In this example, the first and second mounting members (3) and (5) are both long members, and the side wall (31) of the first mounting member (3) has many horizontally elongated holes (3C) for passing electrical wiring, etc. ) are formed at regular intervals in the longitudinal direction of the first attachment part (3). The structure shown in FIG. 4 has a large strength of the mounting member perpendicular to the support member, and is therefore suitable for a planar structure on which a large load is applied, such as a roof in a snowy country.

FIG. 5 shows a long first mounting member (3) similar to that shown in FIG. 4, in which a number of short second mounting members (5) are fitted and fixed. The one shown in Fig. 5 is lighter in weight than the one shown in Figs. Since it is not restricted by the support member, there is a large degree of freedom in the position and number of the second mounting members (5).

In addition, what is shown in FIGS. 4 and 5 is the first mounting member (3
) may be directly supported by the support member, and the inner layer member may be superimposed on these flanges (3a).

In FIG. 6, a third mounting member (11') is interposed between the first and second mounting members (3) and (5). Therefore, a sound-absorbing material, a fire-resistant material, etc. are laid on the 7-lunge (11a) of the third mounting member (11) to form an intermediate layer member, thereby making the space part two-tiered and improving the heat insulation and sound insulation properties of the third mounting member (11). The shape of the attachment member (3) is formed in two stages, and the second attachment member (5) is placed and fixed on this step (11). In this way, it is possible to obtain better effects in terms of strength.

Moreover, FIG. 8 shows a front view of still another embodiment, in which the first mounting member (3) is of the three-stage type, and a second receiving part (11) is provided at the topmost part (11) of the first mounting member (3). 5) is fixed.

Furthermore, FIG. 9 is a front view showing another embodiment, in which the first mounting member (3) and the second mounting member (5) are each of a multi-stage type. Then, the mounting member (3)
Alternatively, a small air layer (12) can be formed in the longitudinal direction of (5), and the benefits of wiring and piping can be further increased.

Figure 10 shows a horizontally long hole (3c) in the side of the first receiving member (3).
) is used (so-called blank board), which is superior in strength compared to the one shown in Figure 5. In particular, this type of device is suitable for locations where wiring or the like is not required.

Note that even when using the first and second mounting members shown in FIGS. 4 to 10, it is of course possible to construct a planar structure such as a roof in the same manner as in the embodiment shown in FIGS. 1 to 3 and described above. be. In addition, in FIGS. 4 to 10, parts common to those in the first embodiment are designated by the same reference numerals, and explanations thereof will be omitted.

In the present invention, the first and second mounting members can be constructed of galvanized steel plates, aluminum plates, other metal plates, metal extrusion molded materials, etc. The inner layer member may be made of only a fireproof material, and the outer layer member may be made of a sound insulating material. The composition of the inner and outer layer members can be changed as appropriate, such as by layering sound-absorbing or fire-resistant materials, but the inner layer must be fire-resistant and the outer layer must have sound-insulating properties. The space between the inner and outer layer members may be filled with a heat insulating material such as glass wool, and the space may be provided with water, gas, etc. piping in addition to electrical wiring.

In the present invention, the face plate such as the roof plate may be made of an appropriate material and structure, such as a galvanized steel plate, an aluminum plate, or another elongated metal plate.

The present invention has been mainly described above with respect to roofs, but
The present invention can be applied to the outer wall of a building, or to the structure under the ceiling or floor of each floor of a building with two or more stories, by simply changing the face plate material.

As explained above, in the surface structure of the present invention, a space is formed on the outside of the building of the supporting member by the inner and outer layer members, so the heat insulation and sound insulation properties are achieved by the heat insulation and sound insulation effects of this space. Also, at least one of the inner and outer layer members has sound absorption,
The use of sound insulation material provides excellent sound insulation, and the use of fireproof material as the inner layer material provides excellent fire resistance, so that in the event of a fire, the electrical wiring installed in the space will be burnt out. Since the time until the fire starts can be made sufficiently long, there will be no power outage or emergency bells and microphones not working immediately after a fire occurs, which can improve safety.

Moreover, since at least one of the first and second mounting members is made of a long material and is orthogonal to the support member, the required strength can be obtained, but the length is shorter than that of a mounting member that uses a stepped mounting member. For example, by changing the height or number of short mounting parts,
It has a large degree of freedom in design and can be made lightweight if necessary.

Furthermore, by separating the first and second mounting members, they can be manufactured easily and inexpensively, and the vertical height of the air layer can be easily adjusted by adjusting the position of the flange of the second mounting member. It is very convenient to perform and has many effects.
