Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial field of application] The present invention relates to a supporting structure for a folded roof, which is supported on a beam through a tight frame and a suspension.

[Conventional technology]

Although the origami roof is lightweight, it has high rigidity due to its origami structure, and is often used for buildings such as factories and warehouses. For example, a lock-up type folding roof is made by connecting the roof-roofing plates of the folding structure in a state in which the joints provided on both side ends of adjacent ones are overlapped with each other. It is formed so as to be supported via a tight frame and a suspension provided on the beam.

On the other hand, the above-mentioned building having a folded roof has a drawback that it looks unattractive if the uneven structure of the folded roof remains exposed on the inner side. On the other hand, conventionally, there is a configuration in which a suspended ceiling is provided on the roofing board via a suspending member, but such a configuration is a structure in which the ceiling is suspended, so it is relatively thin due to restrictions such as support strength. Only the ceiling material could be used, and the satisfactory effects in terms of heat insulation, sound insulation, fire prevention, etc. were not obtained. For example, if the insulation of the origami roof is insufficient, the temperature difference between the inside and outside of the building causes dew condensation on the origami roof. As a means for solving such a problem, it is possible to use a folded roof having a double folded structure, but this folded roof is not only expensive due to its complicated structure, but also thatched roof. There was another inconvenience that the work could not be performed easily, and the inconvenience became more remarkable as the building became larger.

Therefore, as a means for eliminating such inconvenience, it is conceivable to dispose glass wool or the like on the ceiling to provide the functions of heat insulation, sound insulation, and fire protection. In this case, if the structure is such that the ceiling is supported between the beams, not only the supporting strength can be increased, but also the work can be simplified, but for that purpose, a member for constructing the above structure. Need to be fixed to the beam.

However, in the above-mentioned conventional structure having a folded roof, even if an attempt is made to construct a structure for supporting the ceiling plate, there is no means for fixing the member therefor to the beam, so there is no choice but to fix it by welding, etc. On the contrary, it has the drawback of increasing the number of steps.

A "construction structure of a heat insulating roof" capable of solving such a conventional problem is disclosed, for example, in Japanese Patent Application No. 1-142174 (JP-A-3-142174).
8962).

According to this, first, a supporting metal member obtained by processing a long metal thin plate into a metal plate so that the end surface has a substantially T shape is bridged between the beams. This support fitting is formed with a horizontal support portion that supports the entire length of the side edge portion in the longitudinal direction of the ceiling material, and a bent portion in which a standing wall portion rising from the horizontal support portion is folded back at the upper end.

On the other hand, the tight frame is formed by bending both ends in the longitudinal direction of a strip-shaped metal plate at right angles and fastening two plate members formed in a substantially U-shape back to back. Also,
Projecting pieces are attached to the lower portion of the tight frame so as to project to the left and right of the main body along a direction substantially orthogonal to the longitudinal direction of the beam.

When bridging the above-mentioned support metal fittings between the beams, it is sufficient to fit the above-mentioned bent portion of the support metal fitting to the projecting piece of the tight frame fixed on the beam from above. You don't have to.

In this way, after arranging multiple tight frames and supporting metal fittings at the same intervals as the width of the ceiling material, place the ceiling material between adjacent supporting metal fittings, and further tighten the folded roof. , An insulated roof erection structure is built.

[Problems to be solved by the device]

However, in the configuration proposed in the above-mentioned Japanese Patent Application No. 1-142174, the supporting metal fittings are formed by sheet metal working of one thin metal plate, but the tight frame uses two plate members, so The number of parts is increasing, including a plurality of rivets for tightening. A number of tight frames are used on a single beam with a predetermined spacing, and multiple beams are also erected, so the longer the total length of the beam, the longer the structure. As the roof area increases, the number of parts in one tight frame increases, and the total number of parts increases.

Also, since the shape of the two plate members is changed,
Since different bending processes are required and the protruding piece is sandwiched and fixed between the two plate members, the alignment of the parts must be complicated.

As described above, since both the number of parts and the number of manufacturing steps are large, there is a problem that the unit price of the tight frame increases and the total cost for constructing the supporting structure for the folded roof becomes very large.

Therefore, it is left as one of the technical problems in this field to simultaneously achieve the contradictory technical purposes of providing a stable supporting structure for a folded roof that can be constructed at a lower cost.

[Means for solving the problem]

A supporting structure for a folded roof according to the present invention is a supporting structure for a folded roof including a tight frame fixed on a beam of a building and a joiner bridged between the beams. , The main body that rises almost vertically on the beam,
It is formed on the upper part of the main body and indicates the folding roof,
A support portion for attaching a hanging member which is interposed in a fastening portion between adjacent folded roof roof plates, a fixing portion which is formed at a lower end of the main body portion and is seated and fixed on the beam, and the beam. Along a direction substantially orthogonal to the longitudinal direction of the main body part, the projecting piece attached to the lower part so as to project from the lower part of the main body part to both sides, the joiner includes a longitudinal support part for supporting the ceiling material. In the support structure of a folded plate roof, wherein the standing wall rising from the longitudinal support part is folded back at the upper part, and the protruding piece of the tight frame is fitted to the bent part of the joiner. The main body portion, the support portion and the fixed portion are formed by a single plate, and a notch is formed upward from the lower end of the single plate, and the crotch part of the notch is bent in mutually opposite directions, and the crotch part is formed. While sitting on the beam, Parts are fixed, and is characterized in that said joiner is formed by a single plate.

[Operation] According to the above configuration, since the main part of the tight frame is molded with a single plate and the joiner is also molded with a single plate, the components themselves that form the tight frame and the joiner, and a plurality of components are It is possible to reduce fastening members such as rivets for connection. Further, in the work of attaching the protruding piece to the one plate, the positioning of the parts is significantly easier than the work of attaching the protruding piece between the two plates, for example. Therefore, the fact that a tight frame can be manufactured by a simple process also contributes to the reduction of the total cost for constructing a supporting structure for a folded roof.

Moreover, since the crotch part of the fixed part of the tight frame is seated on the beam, there is no gap between the main body part and the beam.
If there is a gap between the main body and the beam, the fixed portion may be deformed due to the weight of the origami roof and an increase in load due to wind force, snow, and the like. However, in the present invention,
By eliminating such a void that may cause deformation of the fixed portion, a stable folded-plate roof support structure can be constructed even if a tight frame made of a single plate is used.

In this way, a stable folding roof support structure that can hold the ceiling material is made even cheaper by simply connecting the joiner supporting the ceiling material to the protruding piece attached to the tight frame. Can be built into.
