Description

The present invention relates to a folded plate roof structure provided with a ceiling support member .

  Conventionally, in a structure having a folded plate roof structure, H-shaped steel is used as a structural material such as a large beam or a small beam. Then, a joiner that is a support member for supporting a heat insulating material or the like is installed between the structural materials, and an outer peripheral portion such as a heat insulating material serving as a ceiling material is placed on the joiner, and a metal folded plate roof is disposed above the heat insulating material. Is installed. By providing the ceiling material, heat insulation and sound insulation can be obtained.

  The ceiling insulation is only placed on the structural material and the joiner, so there is a risk of levitation due to strong winds such as typhoons, and the height of the joiner is low and it does not have sufficient strength In some cases, it was necessary to reinforce such as hanging the joiner along its length. In order to hang the joiner, there was a problem in workability such as having to build a scaffold.

  Therefore, in order to solve such a problem, the ceiling material placed on the joiner is pressed down with the pressing material attached to the joiner, or the edge of the ceiling material is fitted into the recess provided on the side surface of the joiner. It is possible to prevent the rising.

  As a method of pressing down the heat insulating material placed on the joiner with the pressing material, for example, there is a structure of a heat insulating roof described in JP-A-11-44057 (Patent Document 1). The heat insulating roof has a structure in which a plurality of joiners are installed between structural materials such as beams and purlins, and support edges projecting horizontally at the lower end of the joiner and an edge of the heat insulating material as a ceiling material on the structural material. The end portion of the heat insulating material is pressed with a presser fitted on the top of the joiner, and a metal folded plate roof is installed above the heat insulating material.

  The structure of the heat insulating roof can prevent the heat insulating material from floating because the heat insulating material is lifted by the presser. In addition, since the height of the joiner can be increased, the bending strength in the vertical direction is improved, and the need for reinforcement by a lifting tool is eliminated.

  Moreover, as a method of fitting the outer peripheral portion of the heat insulating material into the concave portion provided on the side surface of the joiner, a folded plate support described in Japanese Patent Laid-Open No. 2001-81907 (Patent Document 2) or Japanese Patent Laid-Open No. 10-77721 ( There exists the structure of the heat insulation roof of patent document 3). In Patent Document 2, an inward horizontal piece is formed at the lower end of both legs of a tight frame, and a connecting member attached with a ceiling support member sandwiched between the opposed horizontal pieces is sandwiched.

In Patent Document 3, support brackets are mounted on structural members such as beams and purlins, and a joiner is installed and supported across the support brackets, and a heat insulating material spans between the structural members and is supported by the joiner. This is a structure of a heat insulating roof that is laid on the ceiling and has a metal folded plate roof that is supported by a support metal fitting and is installed. And the press fixture means which presses and fixes a Joiner to the structural material side is provided in the support metal fitting, and the moisture-proof layer is formed in the lower surface of the said heat insulating material.

  In the structure of the heat insulating roof of Patent Document 1 described above, the joiner is formed in a hat shape in cross section, the interval between the vertical pieces facing each other is narrowed downward to the middle, and the middle to the lower are formed in parallel. A presser member, which is formed in a substantially inverted U shape and formed with presser pieces on both sides, is fitted to the top of the joiner so as to press the heat insulating material. And the edge part of a joiner is mounted in the structural material (H-section steel), and is positioned with the positioning tool.

  However, in the above structure, since the joiner is welded and fixed in advance by a positioning tool according to the width dimension of the heat insulating material, the position cannot be changed and the presser is fitted after the heat insulating material is placed on the joiner. However, although the heat insulating material can be prevented from floating, there is a problem that workability is poor.

  Further, the folded plate support of Patent Document 2 is configured such that a joiner is held by a connecting member, and the connecting member is attached between horizontal pieces formed inwardly at the lower ends of both legs of the tight frame. Therefore, the tight frame has to be formed according to the shape of the joiner and the connecting member for fixing the tight frame, and there is a problem that the manufacturing cost increases.

  In addition, the structure of the heat insulating roof of Patent Document 3 is such that a joiner is formed with a substantially horizontal support piece on both sides of the lower end, and a triangular locking head is formed on the upper part. The heat insulating material is pressed by the pressing tool placed on the part. The joiner itself is fixed by a positioning plate while being fixed by pressing and fixing means disposed between the both ends of the structure material (H-shaped steel) and the tight frame.

  In Patent Document 3, as in Patent Document 2, there is a problem that the shape of the tight frame has to be formed in accordance with the joiner and the press fixing means, and the workability of arranging the ceiling material is inferior. is there.

The present invention has been made in view of such circumstances, and can be molded regardless of the shape of the tight frame, facilitates the positioning of the joiner that supports the ceiling material, and improves the construction work of the heat insulating material. and to provide a folded plate roof structure with ceiling material support that. Another object is to provide a folded plate roof structure with ceiling material support member to be able to select a joiner according to the type of ceiling material.

A folded plate roof structure provided with a ceiling material support member composed of a joiner to be inserted, wherein the joiner holder includes a U-shaped holding portion formed by an upper plate, a back plate and a lower plate, and the lower plate The folded piece continuously folded from the front end of the frame comprises a clip portion having a U-shaped cross section together with the lower plate, and the upper flange of the H-shaped steel is inserted into the clip portion with the holding portion of the joiner holder upward. By fixing the joiner holding tool, the end of the joiner is fitted to the opening side of the U-shaped cross section of the holding part so as to be orthogonal to the H-shaped steel, and assembled.
On the upper flange of the H-shaped steel, a tight frame receiving base having the same height as the holding portion having a U-shaped cross section is provided between the opposing joiner holders in the same direction as the H-shaped steel. A tight frame is placed and fixed on a table, and a metal folded plate roof is supported and installed on the tight frame .

  It is preferable that the folded piece of the clip portion of the joiner holder has a substantially U shape that is inclined inward so that the distance from the lower plate becomes narrower toward the opening side. Moreover, it is preferable that the front-end | tip part of the said folding piece is made into the inclination piece inclined outside. In this way, by narrowing the gap on the opening side of the clip part and making the tip part an inclined piece to the outside, it becomes easy to insert the flange of the H-shaped steel and improve the clamping force after insertion. Can do.

Moreover, the folded-plate roof structure provided with the ceiling material support member of the present invention includes a joiner holder and a joiner-holding structure that are installed between the H-shaped steels of a folded-plate roof structure using H-shaped steel as a structural material. A folded-plate roof structure provided with a ceiling material support member composed of a joiner that fits into a fixture, wherein the joiner holder is a U-shaped holding section formed by an upper plate, a back plate, and a lower plate, and The folded piece continuously folded from the front end of the lower plate is made up of a clip portion having a U-shaped cross section together with the lower plate, and the upper flange of the H-shaped steel is attached to the clip portion with the holding portion of the joiner holder downward.

Hereinafter, an embodiment of a ceiling material support member in a folded plate roof structure provided with the ceiling material support member of the present invention will be described with reference to FIGS. 1 and 2. First, FIG. 1 shows an example of a joiner holder 10 constituting a ceiling support member. The joiner holder 10 is formed by a U-shaped holding section 11 that holds a joiner, and a substantially U-shaped clip section 12 that shares a part with the holding section 11 and opens to the opposite side.

  The holding portion 11 is formed in such a size that the tip of the joiner can be inserted from the longitudinal direction, and is formed in a U shape in cross section by an upper plate 11a, a back plate 11b, and a lower plate 11c. Assemble the joiner from the opening side of the front. The size of the holding part 11 may be formed corresponding to the size of the joiner to be assembled. For example, the height dimension may be 30 to 70 mm, the width dimension may be 100 to 200 mm, and the depth dimension may be 30 to 70 mm. .

  The clip portion 12 is formed in a substantially U shape so as to sandwich an H-shaped steel flange, which will be described later, together with a lower plate 11c by a folded piece 12a that is formed by folding the tip of the lower plate 11c of the holding portion 11 in series. Yes. As described above, the clip portion 12 is formed so as to share the lower plate 11 c and opens to the opposite side to the holding portion 11.

  As is clear from FIG. 1B, the folded piece 12a is inclined toward the lower plate 11c so that the distance from the lower plate 11c gradually decreases toward the opening side, and the distal end portion is outside. It is set as the inclined piece 12b inclined in the direction. By tilting the folded piece 12a to the inside of the tip and making the tip 12b an inclined piece 12b that slopes to the outside, it can be easily inserted when inserting the flange portion of the H-shaped steel, and clamping after insertion The power can be improved.

  Therefore, what is necessary is just to form the space | interval of the clip part 12 corresponding to the thickness of the flange part of H-section steel. In addition, the material of the joiner holder 10 is not particularly limited and can be arbitrarily selected from metal, plastic, etc. For example, it is formed by bending a zinc-treated steel sheet having a thickness of 1 to 2 mm. Is preferred.

  Next, based on FIG. 2, the joiner which comprises a ceiling material support member is demonstrated. FIG. 2 (a) shows an example of an H-shaped joiner 21, which is formed integrally by butting back surfaces 21b, 21b of U-shaped members 21a, 21a. In order to integrally form the U-shaped member 21a in cross section, it can be formed by any method such as adhesion, screwing, and screwing. In this way, by forming the U-shaped members 21a and 21a having the same shape in contact with each other and forming them integrally, the bending strength is improved even if they are long, and it is not necessary to suspend them by a hanging tool. The holding force can be increased.

  The H-shaped joiner 21 fits and holds the edge of the ceiling material in the side opening 21c. Therefore, it is not necessary to press the ceiling material with the presser fitted to the joiner's head, and the structure can be simplified and the cost can be reduced. Further, the tip of the joiner 21 is fitted into the holding part 11 of the joiner holding part 10 and the ceiling material can be securely fixed, so that the ceiling material can be prevented from rising. H-shaped joiner 21 should just have the opening surface which can fit a ceiling material from both sides | surfaces, and may be shape | molded integrally.

  Next, FIG. 2B shows an example of a substantially hat-shaped joiner 22 having a cross section, which is formed by projecting a protruding piece 22b bent outward from the lower end of a support portion 22a having a U-shaped cross section. By providing the projecting piece 22b, the bending strength can be increased even if the projecting piece 22b is long. The substantially hat-shaped joiner 22 having a cross-section is suitable for use by placing a ceiling material, for example, a heat shield, on the upper surface of the support portion 22a, as will be described later.

  FIG. 2C shows a cross-section joiner 23 whose cross-sectional shape is formed in a substantially square shape. Bending strength can be increased by using a hollow body with a cross-sectional shape. Similar to the substantially hat-shaped joiner 22 in cross section, the cross-shaped joiner 23 can be used by placing a ceiling material, for example, a heat shield on the upper surface.

  The material of the H-shaped joiner 21, the substantially hat-shaped joiner 22 and the cross-shaped joiner 23 are not particularly limited, and can be formed of any material such as metal or plastic. For example, it is preferable to bend a steel plate having a thickness of 0.5 to 1.2 mm.

Next, an example of an embodiment in which the ceiling material support member having the above configuration is used will be described. 3-6 shows embodiment at the time of combining the H-shaped joiner 21 as a joiner holder 10 and a joiner. First, the joiner holder 10 is attached to the upper flange 32 of the large beam 31 of the H-shaped steel 30 that is a structural material. In this embodiment , the joiner holder 10 inserts the upper flange 32 into the clip portion 12 with the holding portion 11 facing upward. Although the clip portion 12 is gradually narrowed toward the opening, the upper flange 32 can be easily inserted by forming the inclined piece 12b inclined outward at the tip portion. It can be securely held.

  When the upper flange 32 is inserted into the clip portion 12, the holding portion 11 is placed on the upper flange 32. Next, the end portion of the H-shaped joiner 21 is fitted into the holding portion 11 so as to be orthogonal to the large beam 31. The H-shaped joiner 21 is arranged between the large beams 31. Next, the edge part of the heat insulating material 40 which is a ceiling material is inserted into the opening 21 c of the H-shaped joiner 21. Since the heat insulating material 40 is held by the H-shaped joiner 21, it is prevented from rising due to strong winds or the like.

  On the upper flange 32, a tight frame receiving base 51 for mounting and fixing the tight frame 50 is provided. The joiner holder 10 is provided on the girder 31 so as to face each other with the tight frame cradle 51 therebetween. The shape of the tight frame cradle 51 is not particularly limited. For example, it can be a lip groove as shown in FIGS. 3 and 4, and is preferably the same height as the holding portion 11. The tight frame 50 may be placed and fixed on the tight frame base 51, and the folded roof 52 may be installed by a known method.

  As described above, by attaching the clip portion 12 of the joiner holder 10 to the upper flange 32 of the H-shaped groove and inserting the end portion of the H-shaped joiner 21 into the holding portion 11 mounted and fixed on the upper flange 32, Even if it does not reinforce with a hanging tool, the heat insulating material 40 can be reliably hold | maintained and airtightness can be improved. Moreover, since the construction is easy, work efficiency is good.

FIG. 5 shows a case in which the ceiling material support member is a combination of the joiner holder 10 and the H-shaped joiner 21. However, in the point that the holding portion 11 is attached to the lower side of the upper flange, FIG. 3 and FIG. Different from the embodiment shown. Therefore, the same reference numerals are assigned to other identical components, and description thereof is omitted.

  That is, FIG. 5 shows the case where it is attached to the beam 33, and the joiner holder 10 inserts the upper flange 34 into the clip part 12 with the holding part 11 facing down. The clip portion 12 can easily insert the upper flange 34 by the inclined piece 12b at the tip, and can securely hold the upper flange 34 after insertion.

As described above, when the holding portion 11 is attached toward the lower side of the upper flange 34, the tight frame 50 can be directly fixed on the small beam 33. Also in this embodiment , the construction workability, airtightness, prevention of lifting due to strong wind, etc. can all have the same effects as the usage examples shown in FIGS.

Next, the embodiment shown in Figure 6. Figure to 8 figure shows a case where the ceiling material supporting member combining Joiner holder 10 and the cross section hat joiner 22. In this embodiment , a sheet-like heat shield 41 is used as a ceiling material, and the same reference numerals are given to the same configurations as those in the previous embodiment, and the description thereof is omitted.

  The clip portion 12 of the joiner holder 10 is held between the upper flanges 32 of the large beams 31 of the H-shaped steel 30. At this time, the holding portion 11 of the joiner holder 10 is fixed in a state of being placed on the upper side of the upper flange 32. Since the joiner holder 10 holds the upper flange 32, the position can be adjusted by shifting it to the left or right.

  Next, the end portion of the substantially hat-shaped joiner 22 is inserted into the holding portion 11. At this time, the edge of the sheet-like heat shield 41 is placed on the upper surface of the substantially hat-shaped joiner 22 in cross section, and the end of the substantially hat-shaped joiner 22 in cross section is inserted into the holding portion 11 and at the same time, the corner of the heat shield 41 is placed. It is preferable to insert the part. In this way, the end portion of the substantially hat-shaped joiner 22 and the corner portion of the heat shield 41 can be inserted into the holding portion 11 at the same time and fixed together. The heat shield 41 may be placed on the upper surface of the joiner 22 after the substantially hat-shaped joiner 22 is inserted into the holding portion 11.

  It is preferable that the edges of the heat shielding material 41 placed and abutted on the upper surface of the substantially hat-shaped joiner 22 are integrally connected with an adhesive tape or the like, for example, an aluminum tape or the like. Thus, by connecting the edges of the heat shield material 41, the heat shield material can be reliably prevented from rising.

  When the substantially hat-shaped joiner 22 is used, the heat shield 41 is placed on the protruding piece 22b, and the edge of the heat shield 41 is attached to the side surface of the support portion 22a of the substantially hat-shaped joiner 22 with aluminum tape. Etc., may be fixed together. Further, the heat insulating material 40 is placed on the projecting piece 22b instead of the heat shielding material, and the edge of the heat insulating material 40 is integrally fixed to the side surface of the support portion 22a of the substantially hat-shaped joiner 22 with aluminum tape or the like. Also good. Further, the heat insulating material 40 may be integrally fixed with the upper surface of the support portion 22a and aluminum tape or the like.

As described above, in the combination of the joiner holder 1 and the substantially hat-shaped joiner 22 in cross section, when the holding portion 11 is attached to the upper flange 32 facing upward,
As in the case of using the H-shaped joiner 21, a tight frame receiving base 51 is provided on the large beam 31, and the tight frame 50 is placed and fixed on the tight frame receiving base 51. After the tight frame 50 is placed and fixed, the folded plate roof 52 is installed.

FIG. 8 is a case where the ceiling material support member is combined with the joiner holder 10 and the substantially hat-shaped joiner 22 in cross section, but in that the holding portion 11 is attached to the lower side of the upper flange. 7 is different from the embodiment shown in FIG .

  That is, FIG. 8 corresponds to the combination of the joiner holder 10 and the H-shaped steel joiner 21 shown in FIG. 5, and the ceiling material support member in which the joiner holder 10 and the substantially hat-shaped joiner 22 are combined is reduced. The case where it attaches to the beam 33 is shown. The joiner holder 10 inserts the upper flange 34 into the clip portion 12 with the holding portion 11 facing down. As described above, when the holding portion 11 is attached toward the lower side of the upper flange 34, the tight frame 50 can be directly fixed on the small beam 33. Therefore, effects such as construction workability, airtightness, and prevention of lifting due to strong winds can be achieved.

  Although the illustration of the use example of the cross-shaped joiner is omitted, it can be used in the same manner as the substantially hat-shaped joiner 22 in cross section, and the heat shield 41 is placed on the upper surface and the abutted shield is provided. What is necessary is just to connect the edge part of heat materials with an aluminum tape etc. FIG.

  In addition, in the said usage example, although the case where the joiner holder 10 was attached to the upper flange of H-shaped steel was demonstrated, it is also possible to attach to a lower flange. Of course, also when attaching to a lower flange, you may attach the holding | maintenance part 11 of the joiner holder 10 toward the upper and lower sides of a lower flange.
