Description

  The present invention relates to a reinforcing structure of a folded roof when a folded roof using a folded plate is used as a roof structure of a building.

In general, a folding plate used as a roof member is fixed by being fitted to a tight frame fixed on the upper side of a roof beam. And as a reinforcement structure for preventing the bending of the folded roof, usually, the number of the tight frames is increased. Further, as another method, for example, a method that also serves as a floor structure on a folded plate as in Patent Document 1 has been proposed. In the invention of Patent Document 1, a reinforcing material is installed between ridges of a folded plate, the reinforcing material straddles between the ridges, a vertical piece hanging downward from the flat plate portion, and a swelling of the folded plate ridge. It is comprised by the leg part engaged with a protrusion part. This reinforcing member prevents deformation such as bending of the folded plate.
Japanese Patent No. 2644325

  However, in the reinforcement method by increasing the number of tight frames, if reinforcement of the folded plate roof is necessary at the time of extension, etc., remove the folded plate roof once and install a roof reinforcing beam etc. that supports the tight frame. Since it is necessary to install, install a tight frame on it, and install an origami roof again, it is difficult to respond.

  Further, in the prior art as disclosed in Patent Document 1, the reinforcement member and the folding plate are fixed only by engaging the leg portion with the bulging portion of the folding plate mountain portion. May move away from the plate. That is, as shown in the schematic diagram of FIG. 5, the amount of deflection of the reinforcing member D and the folding plate E is different, and the reinforcing member slides in the longitudinal direction of the folding plate, and the bending of the folding plate E is not integrated. Etc. will be permitted. In addition, the interval between the bulging portions of the ridges is pushed by the leg portions and spreads in the repeated direction of the folding plate, and deformation such as deflection in the repeated direction of the folded plate is allowed. Therefore, it is necessary to perform continuous arrangement like a floor structure and restrain the movement of the reinforcing member. However, it is inefficient when a floor structure is not required or when partial reinforcement is required. Therefore, the subject of this invention is providing the reinforcement structure of the folding plate roof which can prevent deformation | transformation, such as a bending of a folding plate roof, even if it provides a reinforcing material independently.

  In the first aspect of the present invention, the roof is formed using a folded plate in which mountain portions and trough portions extending in parallel to each other are alternately formed, and straddles between adjacent mountain portions of the folded plate, along the valley portion. A long reinforcing member is formed, and the concave portion of the folding plate is formed between the adjacent peak portions of the folding plate via a valley portion, and the reinforcing member is formed into a beam shape having a closed cross section. A reinforcing structure for a folded-plate roof, wherein the reinforcing member is fixed so as not to move with respect to the folded plate.

  As the material of the reinforcing member, steel, resin, stainless steel, etc. can be used. However, considering strength and weather resistance, it is preferable to use steel or stainless steel.

The beam type formed by the concave portion of the folding plate and the reinforcing member may be a beam type having a cross section in which the space surrounded by the concave portion of the folding plate and the reinforcing member is closed. That is, the shape can be a square shape, a circle, a polygon, or the like. Moreover, the shape which has an unevenness | corrugation in a part of beam type may be sufficient.

The reinforcing member and the folding plate are fixed with respect to the folding plate so that the reinforcing member and the folding plate are not integrated as shown in FIG. 5 and are not a fixing means that allows deformation of the folding plate. It is in a fixed state so as not to.

  According to the configuration of claim 1, since the reinforcing member is fixed so as not to move with respect to the folding plate, the reinforcing member does not slip in the longitudinal direction of the folding plate, and the folding plate is deformed in the longitudinal direction. On the other hand, the reinforcing member and the concave portion of the folding plate can be integrally resisted. Therefore, deformation of the folded plate in the longitudinal direction is not allowed. In addition, since the reinforcing member is fixed so as not to move with respect to the folding plate, the interval between the crests is constrained with respect to the repeating direction of the folding plate, and resistance to spreading in the repeating direction of the folding plate. Yes, and does not allow deformation in the direction of repeated folding.

That is, since the reinforcing member is fixed so as not to move with respect to the folding plate, the reinforcing member and the concave portion of the folding plate are integrated, and the beam is formed in a closed cross section by being surrounded by the reinforcing member and the concave portion of the folding plate. The mold functions in the same way as a general beam. Therefore, it is possible to resist the deformation of the folded plate. Furthermore, since the beam type has a closed cross section, it is difficult to buckle.
Further, since the reinforcing member is fixed so as not to move with respect to the folding plate, it is not necessary to provide the reinforcing member continuously as in Patent Document 1, and it can be used for partial reinforcement or the like.

Further, a fitting portion is provided at the top of the crest portion of the folded plate, and the reinforcing member is fitted by sandwiching the fitting portion from both sides and fixed to the folded plate. Is.

As the fitting part provided at the top of the crest of the folded plate, for example, a fitting part bulging in the horizontal direction is provided on both sides of the top of the crest, or recesses are provided on both sides of the top of the crest. A method for forming the fitting portion can be used. The reinforcing member is fixed to the folding plate by being fitted to the fitting portion as described above by sandwiching the reinforcing member from both sides in the repeated direction of the folding plate.

Further, the reinforcing member can be attached to the folded plate by an easy configuration in which the fitting portion is sandwiched from both sides by tightening a bent portion formed on each side of the reinforcing member and a holding plate opposed to the bent portion. It is fixed so as not to move. Moreover, there is no need to make a hole in the folded plate, so there is no risk of rain leaks.

Furthermore, the reinforcing member is configured to protrude upward from the folding plate crest.

For example, the reinforcing member is configured in a substantially U-shape, and is placed with the released side facing down and facing the recessed portion of the folded plate, and fixed to the crest of the folded plate at the U-shaped leg portion. By making it, it can be set as the structure which protruded upwards from the folding plate mountain part.

According to such a configuration, the concave portion of the folding plate and the beam-shaped beam back having a closed cross section formed by the reinforcing member are higher than the folding plate or the reinforcing member itself, so that the secondary moment of the cross section is It becomes larger and deformation such as deflection is suppressed.

  According to the reinforcing structure of the folded-plate roof according to claim 1, since the reinforcing member is fixed so as not to move with respect to the folded plate, the recessed portion of the reinforcing member and the folded plate can be integrated. Therefore, deformation and buckling such as bending of the folded plate can be resisted by the concave portion of the folded plate and the beam shape having a closed cross section formed by the reinforcing member. In addition, since the reinforcing member and the concave part of the folding plate are integrated, even if the beam type is provided independently for the folding plate, the deformation of the folding plate can be prevented, and the partial part of the folding plate roof can be prevented. Can be reinforced.

In addition , the reinforcing member can be fixed so as not to move with respect to the folding plate by an easy configuration that only fits. In addition, there is no need to make a hole in the folded plate, so there is no risk of rain leakage.

In addition , the concave portion of the folded plate and the reinforcing member increase the height of the beam having a closed cross section and increase the second moment of the cross section, so that deformation such as deflection is suppressed.

  DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, embodiments of reinforcing a folded roof according to the present invention will be described with reference to FIGS.

  Example 1 is an example of the reinforcing structure of a folded roof according to the present invention, and will be described with reference to FIGS. FIG. 1 is a perspective view of a reinforcing structure of a folded roof that is an embodiment of the present invention, FIG. 2 is a cross-sectional view of the reinforcing structure of the folded roof that is an embodiment of the present invention, and FIG. FIG. 4 is a perspective view when the reinforcing structure of the folding plate roof according to the embodiment of the present invention is used when a solar panel is installed in the solar panel, and FIG. 4 is a modified example of the reinforcing structure of the folding plate roof according to the embodiment of the present invention. FIG. 5 is a schematic view when the folded plate and the reinforcing member are not fixed.

  As shown in FIG. 1, a roof of a building is formed by a folded plate 3 in which mountain portions 1 and valley portions 2 extending in parallel with each other are alternately repeated. The folded plate is a stainless steel plate having a thickness of 0.6 mm. The folded roof is fixed to the building structure by a tight frame as shown in FIG. On the top of the ridge 1 of the folded plate, there are provided fitting portions 4 that bulge about 6 mm on both sides in the repeating direction.

  A reinforcing member 5 is provided between adjacent mountain portions 1 of the folding plate 3. As shown in FIGS. 1 and 2, the reinforcing member 5 has a substantially square U-shape formed by a flat plate portion 5 a and a leg portion 5 b, and is long along the valley portion 2 of the folded plate 3. It is composed of a scale. The leg portion 5 b is provided with a bent portion 5 c that is bent so as to correspond to the shape of the fitting portion 4 at the top of the peak portion 1 of the folded plate 3. In addition, a holding plate 6 having a shape paired with the bent portion 5c of the reinforcing member 5 can be fixed to the leg portion 5b of the reinforcing member 5 with screws or bolts. The reinforcing member 5 is arranged so as to be bridged over a plurality of tight frames that support the folding plate 3.

  The reinforcing member 5 is disposed so that the U-shaped open side is opposed to the valley portion 2 of the folding plate and straddles between the adjacent mountain portions 1 of the folding plate 3. The reinforcement member 5 is fixed by fitting the bent portion 5c of the leg portion 5b and the fitting portion 4 of the folded plate 3 with the holding plate 6 so as to be sandwiched from both sides of the folded plate. . Therefore, since the fitting part is strongly sandwiched by tightening with screws or bolts, the reinforcing member 5 is prevented from moving relative to the folded plate 3 in either the longitudinal direction or the repeated direction of the folded plate. ing.

    According to this configuration, as shown in FIG. 1 (B) and FIG. 2 (portion surrounded by a two-dot chain line), the adjacent ridges 1 of the folded plate 3 are configured via the valleys 2. It is formed into a substantially square-shaped beam mold 8 whose cross section is closed by the recess 7 and the reinforcing member 5. Since the reinforcing member 5 does not move with respect to the folding plate 3, the beam type 8 does not slide the reinforcing member 5 in the longitudinal direction of the folding plate 3, and the longitudinal direction of the folding plate 3. The concave portion of the reinforcing member 5 and the folding plate 3 can be integrally resisted against deformation. Therefore, deformation of the folded plate 3 in the longitudinal direction is not allowed. Also, with respect to the repeating direction of the folding plate 3, since the reinforcing member 5 is fixed so as not to move with respect to the folding plate 3, the interval between the peak portions 1 is constrained. It is possible to resist the spreading of the folding plate 3 and does not allow deformation of the folding plate 3 in the repeating direction.

  That is, since the reinforcing member 5 is fixed so as not to move with respect to the folding plate 3, the concave portions of the reinforcing member 5 and the folding plate 3 are integrated and closed by being surrounded by the concave portions of the reinforcing member 5 and the folding plate 3. The beam mold 8 formed in the cross section is as shown in FIG. 1B, and functions in the same manner as a general beam material. Therefore, it is possible to resist the deformation of the folding plate 3. Furthermore, since the beam mold 8 has a closed cross section, it is difficult to buckle.

  Further, since the beam mold 8 is made not to move with respect to the folding plate 3, it is not necessary to arrange them continuously, and an effect can be obtained even if they are arranged alone. It can also be used as a general reinforcement.

That is, when the solar panel 9 is installed on the folding roof as shown in FIG. 3, it is common to increase the number of tight frames B to which the folding roof is fixed. If the reinforcement structure A of the folding plate roof of Example 1 is used, it can reinforce by using the reinforcement structure A by matching the solar panel 9 with the installation part in the upper part of the folding plate roof. Therefore, there is no need to remove the folded roof and reinforce the tight frame B and the reinforcing beam C. Therefore, it is effective for extension or partial reinforcement.

  In addition, since the fitting portion 4 provided in the peak portion 1 of the folding plate 3 can be formed with a simple configuration that is fitted from both sides by the bent portion 5c of the reinforcing member 5 and the pressing plate 6, Construction is easy. Further, since the reinforcing member 5 can be fixed without making a hole in the folded plate, there is no need to worry about rain leakage.

  In addition, the beam mold 8 is configured to protrude above the peak portion 1 of the folded plate 3 by the leg portion 5 b of the reinforcing member 5. Therefore, the beam back of the beam mold 8 is higher than the crests of the folded plate and the reinforcing member itself, so that the secondary moment of the cross section is increased and deformation such as deflection is suppressed.

  In Example 1, the reinforcing member 5 is configured to protrude above the peak portion 1 of the folded plate 3. However, as shown in FIG. 4, the reinforcing member 5 is configured to have the same height as the peak portion. Also good.

  The embodiments of the present invention have been described above. However, the present invention is not limited to the above-described embodiments, and it goes without saying that design changes within a range not departing from the gist of the present invention are included in the present invention. is there.
