Description

  The present invention relates to a support that supports a roof material by being fixed to a roof base when a metal folded plate roof is installed on a roof base such as a main building.

  As a roofing structure suitable for large space buildings such as factories, warehouses, and gymnasiums, and small buildings with simple structures, metal folded-plate roofing materials (hereinafter simply referred to as “folded plates”) are joined together. So-called boltless folded plate roofs are widely used. As shown in FIG. 4, the basic structure of such a folded-plate roof is that a substantially trapezoidal tight frame 2 is fixed to a top surface of a roof base composed of a purlin 1 and the like at predetermined intervals, and is suspended from the top of the tight frame 2. A child plate 3 is attached, and a folded plate 4 having a substantially valley-shaped cross section having a bottom surface portion 41 at the center in the width direction is placed in conformity with the mountain-valley shape of the tight frame 2. The seam is sandwiched between the tops. The roof gradient for drainage is provided along the longitudinal direction of the folded plate 4 (direction perpendicular to the paper surface).

  The folded plate roof thus constructed tends to expand and contract in the longitudinal direction by being exposed to external heat factors such as drastic changes in outside air temperature, solar radiant heat, and wind and rain. When the stress and frictional force are accumulated, the folded plate 4 is deformed like a wave and generates an explosive sound called buckling. In addition, if a load due to repeated expansion and contraction is accumulated, there is a possibility that the fasteners 5 such as bolts and nuts fixing the suspension 3 are loosened or damaged, or in the worst case, the folded plate 4 is scattered. There is also. Such a problem becomes more serious as the length of the folded plate 4 increases.

Therefore, Patent Documents 1 to 3 and the like disclose a roof support structure that absorbs the thermal expansion and contraction of such a folded plate roof. As shown in FIG. 5, the roof support structure has a bottom 31 of the hanging element 30 formed in an inverted T-shaped cross section, and the bottom 31 is held from both sides by a saddle 60 having a groove 61 having an inverted T-shaped cross section. It is what is held. The hanging member 30 follows the thermal expansion and contraction of the folded plate 4 and slides in the groove 61 of the saddle 60 in the gradient direction, whereby the stress of the folded plate 4 is released. In order to make the hanging member 30 slide smoothly, a liner material 62 made of a highly lubricating resin material is interposed inside the groove 61.

  Even in the above-described roof support structure in which the hanging element 30 slides and absorbs the thermal expansion and contraction of the folded plate 4, the tight frame 2 that supports the hanging element 30 and the saddle 60 is fixed on the roof base composed of the main building 1 and the like. The Here, as shown in FIG. 6A, when the upper surface of the purlin 1 etc. is inclined according to the roof slope, by attaching the tight frame 2 so as to stand upright with respect to the upper surface of the purlin 1, The inclination of the saddle 60 and the suspension 30 (sliding direction of the suspension) can be matched to the roof gradient without any hindrance.

  However, depending on circumstances in design or construction, as shown in FIG. 6 (b), the main building 1 may be installed without being inclined. In this case, since the upper surface of the main building 1 is horizontal, even if the tight frame 2 is attached in a conventional manner, the inclination of the saddle 60 and the suspension 30 cannot be matched with the roof slope.

  Therefore, the present invention provides a roof structure that absorbs thermal expansion and contraction of a folded plate by sliding a sling held by a saddle, even when the upper surface of the main building is not inclined according to the roof slope. The present invention provides a support that can easily match the inclination of the saddle and the sling to an arbitrary roof slope.

  In order to achieve the above-described object, the folded-plate roof support tool of the present invention includes a hanger sandwiched between the goby joints of the folded-plate roof and a roof slope that hugs the bottom of the hanger. A saddle that is slid in a direction and a leg that is connected to the lower part of the saddle and holds the saddle and a hanging member on a roof and other roof foundations, and the saddle is provided near the upper part of the leg. It is characterized in that the sliding direction of the suspension can be changed according to the roof gradient by being pivotably connected to the leg portion via the horizontal shaft member.

  With this configuration, the roof slope can be adjusted by arbitrarily tilting the direction of the saddle and the hanger regardless of whether the upper surface of the roof base such as the main building is inclined according to the roof gradient or not. Can be matched. Since the saddle and the leg are connected in the vicinity of the upper part of the leg, that is, at a position closer to the roof surface than the roof base, the hanging member can easily follow smoothly when the folded-plate roof expands and contracts.

  Further, in the support device of the present invention, the leg portion is configured by a pair of substantially L-shaped leg half portions each including a bottom plate portion and an upright plate portion, and a hanging plate portion protruding from the bottom portion of the saddle. Is sandwiched between the two standing plate portions of the leg portion, and the leg portion and the saddle are connected to each other by a bolt member penetrating the hanging plate portion and the both standing plate portions.

  According to this configuration, the structure of the entire support can be simplified and manufactured at low cost, and can be easily assembled and fixed to the roof base. Further, if the shaft member is fastened by using a bolt member, the inclination of the saddle and the suspension can be easily fixed, and the work is excellent in workability because the fastening work is performed at one place.

  Regarding the configuration of the saddle and the suspension in the support of the present invention, the bottom of the suspension is formed in an inverted T-shaped longitudinal section, and the saddle is provided with a groove section having an inverted T-shaped longitudinal section that opens upward. In this groove portion, the bottom portion of the hanging member can be held. By adopting such a cross-sectional form, even if a strong external force acts on the hanging member due to thermal expansion and contraction of the folded plate or wind pressure, the hanging member can be held firmly and stably.

  Further, the saddle may be configured by pairing saddle halves having a U-shaped cross section or a horizontal U shape. Such a configuration is advantageous for reducing manufacturing costs and improving the efficiency of assembly work.

  Further, by placing a liner material made of a highly lubricating resin material inside the groove portion of the saddle, the suspension can be slid more smoothly.

  The folding plate roof support tool of the present invention configured as described above is provided with a saddle and a hanging hook even when the upper surface of a purlin or other roof base to which the support tool is attached is not inclined in accordance with the roof slope. Can be easily matched to an arbitrary roof slope, and the sliding of the suspension can be secured stably over a long period of time.

  Hereinafter, embodiments of the present invention will be described with reference to the drawings. FIG. 1 is a perspective view showing an overall configuration of a folded plate roof support according to an embodiment of the present invention, FIG. 2 is a front view of the support, and FIG. 3 is a side view of the support. Components common or corresponding to those of the conventional roof support structure shown in FIG.

  The support 70 includes a leg portion 80 fixed to the main building 1 and other roof bases, a saddle 60 connected to the upper portion of the leg portion 80, and a suspension 30 held by the saddle 60.

  The leg portion 80 is a member made of steel or the like and replaces the conventional tight frame 2 (FIG. 5). The leg portion 80 is configured by pairing a substantially L-shaped leg half body 83 composed of a bottom plate portion 81 and an upright plate portion 82. The bottom plate portion 81 of the leg half body 83 is disposed on the upper surface of the purlin 1 along the length direction of the purlin 1 etc., and is fixed via a fixture such as welding or a bolt / nut. The upright plate portions 82 of the leg half bodies 83 rise substantially perpendicular to the upper surface of the purlin 1 or the like relative to each other. A shaft member made up of a bolt member 84 and the like is attached to the upper portions of the upright plate portions 82 in the horizontal direction so as to be parallel to the purlin 1, and the saddle 60 is connected to the bolt member 84.

  The saddle 60 has a structure in which a saddle half body 63 made of steel or the like is paired and a liner material 62 is interposed inside thereof. The illustrated saddle half body 63 has a U-shaped cross section and includes a hanging plate portion 64 projecting downward from the bottom thereof. The hanging plate portions 64 of the two saddle halves 63 are sandwiched between the two standing plate portions 82 of the leg 80 in a state of being overlapped with each other, and the bolt members 84 penetrating the both hanging plate portions 64 and the both standing plate portions 82. Connected by Thereby, as shown in FIG. 3, the saddle 60 can freely rotate in a vertical plane orthogonal to the purlin 1. Furthermore, a female screw that is screwed into the bolt member 84 is tapped on one side of the upright plate portion 82, and the angle of the saddle 60 is fixed when the bolt member 84 is fastened.

  The liner material 62 sandwiched between the two saddle halves 63 is formed of a highly-lubricating resin material such as polyolefin, polyacetal, fluororesin, polyamide, polyester, ABS resin, polycarbonate, or phenol resin. The liner material 62 is formed with a groove section 61 having a reverse T-shaped longitudinal section that penetrates in the front-rear direction and opens upward, and an opening edge 64 of the groove section 61 protrudes from the upper surface of the saddle half 63.

  The hanging element 30 is a member formed by bending a steel plate in the same manner as the conventional one shown in FIG. 5, and the top portion 32 of the upright portion is sandwiched between the gouge fastening portions of the folded plate 4. The bottom 31 protrudes left and right and has an inverted T-shaped cross section. The length of the hanging element 30 is formed to be approximately 2 to 4 times the length of the saddle 60, and the bottom 31 is held in the groove 61 of the saddle 60 and slides in the front-rear direction. At both ends in the front-rear direction of the bottom portion 31, bent pieces 33 for preventing the saddle 60 from coming off are provided.

  As described above, the support tool 70 according to the present invention is provided with a mechanism for adjusting the inclination of the saddle 60 on the upper part of the leg portion 80 that holds the saddle 60 and the hanging element 30. Therefore, even if the angle of the purlin 1 is in any state as shown in FIGS. 6A and 6B, the sliding direction of the suspension 30 can be matched according to an arbitrary roof slope. Since the saddle 60 and the leg portion 80 are connected via the shaft member disposed at the upper portion of the leg portion 80, that is, at a position close to the folded plate 4, the follower 30 also follows when the folded plate 4 expands and contracts. As compared with the case where the connecting portion is provided in the vicinity of the lower portion of the leg 80, the operation is performed more smoothly. In addition, since only one shaft member is required to connect the saddle 60 and the leg 80, the overall structure is simplified, and it can be manufactured at a low cost. Work is also easy. Thereby, the folded-plate roof of the structure which slides the hanging element 30 and absorbs thermal expansion-contraction can be implemented more suitably than before. Note that the present invention is not limited to the illustrated embodiment, and can also be implemented using a similar mechanism having the same function.

It is a perspective view which shows the whole structure of the support tool of the folded-plate roof which concerns on embodiment of this invention. It is the front view which looked at the said support tool from the roof gradient direction. It is a side view of the said support tool. It is a longitudinal cross-sectional view which shows the basic structure of the conventional folded-plate roof. It is a perspective view of the saddle and the hanging member used for the conventional roof support structure which absorbs the thermal expansion and contraction of a folded-plate roof. It is explanatory drawing which shows the problem in the roof support structure of FIG.
