Description

  The present invention relates to a folded plate roofing material which is easy to install, is excellent in heat insulation, and can maintain durability for a long time after installation, and a method of installing the same.

  In recent years, folded sheet (folded sheet) roofing materials are widely used for the roofs of buildings such as convenience stores, warehouses, large-scale stores in the suburbs, etc. along the main roads because they can cover large roof areas at low cost. It is done. This folded sheet roofing is formed of a metal plate to prevent condensation on the inner back surface, to prevent reflection of sound generated in the room, and further to high temperature in the room due to direct sunlight in summer and low temperature in the room due to cold in winter. In order to cope with it, it is necessary to attach a heat insulating material to obtain a heat insulating effect.

  If a heat insulating material is laid on the ceiling, for example, wiring work of electric cords on the back of the ceiling and installation of a duct such as an air conditioner become extremely difficult. It has been known. (See Patent Document 1 and Patent Document 2)

JP-A 5-86690 Japanese Utility Model Application Publication No. 4-66230

  The folded plate roofing material provided with the heat insulating material described in Patent Document 1 and Patent Document 2 described above has a sandwich structure in which the heat insulating material is sandwiched between two folded plate roofing materials. In the case of using a roof material sandwiching such a heat insulating material, the following problems occur.

  As the first problem, since the heat insulating material is sandwiched between the two folded sheet roofing materials as described above, the folded sheet roofing material required per unit area when constructing the roof is It becomes two sheets, requires two folded sheet roof materials of the same shape over the whole roof, and it will be expensive in constructing the roof.

  A second problem is that the roof construction work can not be performed efficiently and safely. Specifically, according to the folded sheet roofing material described in the above cited reference, for example, when constructing a roof, the lower folded sheet roofing material is first firmly fixed to a purlin supporting the roof, and the heat insulating material The upper folded sheet roofing material is put on the upper surface of the heat insulating material, and the upper folded sheet roofing material, the lower roofing material, and the heat insulating material sandwiched between them are fixed to the main building. It will be necessary.

  Therefore, the work in the main house which is a roof support material increases, and in order to finish construction of a roof, it is required to require a proper construction period and to ensure sufficient safety during the operation during that period.

  In addition, when constructing a roof, it is necessary to carry out in a safe working environment where the weather is good and strong winds are not blowing, so completion of roof construction work due to unseasonable weather based on the recent deterioration of the weather environment. There is a possibility that the schedule for the completion of construction work may not be in time. Such a delay of schedule causes a negative effect on the schedule of interior work in the building after roof construction, which is a serious problem.

  Therefore, unlike the construction of the roofing material mentioned above, the construction method of the roof which attaches this on the top of a purlin is also carried out using only the heat insulating material and one folded sheet roofing material put on the upper side of this heat insulating material. . In this case, after the heat insulating material is connected and fixed to the roof purlin, if the heat insulating material and the folded plate roofing material covering the upper side are connected and fixed, the dimensional relationship between the mother building and the folded plate roofing material is the heat insulating material. Thickness will be involved. This causes the following new problems.

  For example, as the first problem, not only snowfall areas associated with recent weather variations as described above, but also south coast areas where snow does not fall so much, due to a drop in the low pressure over the south coast, etc. Sometimes. As described above, when an unexpectedly large amount of snow is deposited on the roof by the combination of a single folded sheet roofing material and a heat insulating material as described above, the weight causes the heat insulating material to be crushed (plastic deformation ), Space may occur between the folded sheet roofing material and the heat insulating material.

  In particular, when such a phenomenon occurs at the connection portion between adjacent folded sheet roof materials, a gap is generated at the goby part of the two folded sheet roof materials. Once such a gap is generated, it may be melted with snow and deposited, or melted away, or when a large amount of rain such as so-called guerrilla heavy rain that frequently occurs in recent years has fallen, etc. There is a possibility that water may infiltrate from the gap generated between the two and leak from the roof to the room through the ceiling.

  In addition, even if the heat insulating material is plastically deformed and remains recessed, the folded plate roofing material may be made of metal and may return to the original state, so if the gap between these is large, for example, it is considerably large with recent weather fluctuations. A downburst occurs, which causes positive pressure to be applied to the folded sheet roofing material, strong wind is blown to the roofing material part as the large low pressure passes, and the roof is pulled upward by negative pressure. Repeatedly, so-called alternating load acts on the folded plate roofing material, and the mechanical strength of the above-mentioned gap portion of the roofing material is reduced, causing breakage or in the worst case the folded plate roofing There is also a possibility that the material is blown away by strong wind and peeled off from the roof.

  The object of the present invention is to provide a folded plate roofing material which is easy to install, is excellent in heat insulation, and can maintain durability for a long time after installation, and a method of installing the same.

  In the supporting portion main body 310, two reinforcing ribs 315 extend in the longitudinal direction. By forming such a rib 315, the support main body 310 always keeps the distance between the metal roof material 100 and the purlin 50 constant while the folded sheet roofing 1 is attached to the purlin 50. There is.

  The connecting bent portion 340 is bent in a predetermined shape so as to be just fitted to the lower fly portion 132h of the metal roof material 100 corresponding to this.

  Two fixed screw holes 321 are formed in the roof material fixing portion 320 at predetermined intervals in the width direction. The fixing screw screw holes 321 are screw holes for fixing the hanger 300 to the metal roofing material 100. On the other hand, in the purlin fixing portion 330, a fixing screw insertion hole 331 is formed at one position substantially at the center in the width direction. The fixing screw screw hole 331 is a screw hole for fixing the sling 300 to the purlin 50. Then, when attaching the folded plate roofing material 1 to the purlin 50 via the suspension 300, the self tapping screw 350 is screwed into these fixing screw screw holes 321, 331.

  By attaching the folded plate roofing material 1 to the purlin 50 at an appropriate distance via the sling 300, the strength of the sling 300 and the strength of the metal roofing material 100 combine to form, for example, a downburst on the folded plate roofing material 1. The metal roofing material 100 causes permanent deformation (plastic deformation) without the metal roofing material 100 crushing the heat insulation foundation material 200 even if excessive positive pressure is applied or snow accumulates and a considerable amount is deposited. To prevent.

  Subsequently, a construction method for attaching the folded sheet roofing material 1 according to the present embodiment to a building under construction (hereinafter simply referred to as “construction method” and a construction site for attaching the folded sheet roofing material to a building is simply referred to as “construction site” Will be described. FIG. 7: is a perspective view which shows the method of fitting the heat insulation base material 200 to the metal roof material 100 of the folded-plate roof material 1 shown in FIG. Moreover, FIG. 8 is an end elevation which shows the method of fitting the heat insulation base material 200 to the metal roof material 100 of the folded-plate roof material 1 shown in FIG.

  As a construction procedure, the metal roofing material 100 and the heat insulation foundation material 200 are separately carried into the construction site, or the heat insulation foundation material 200 is carried to the construction site with the heat insulation foundation material 200 attached at the factory. The procedure of attaching the heat insulation base material 200 to the metal roofing material 100 will be described below. Note that this mounting procedure is common to both of the case of mounting the metal roofing material 100 and the heat insulating base material 200 at the construction site and the case of mounting at the factory.

  When constructing the folded sheet roofing material 1, first, the metal roofing material 100 is turned over and the heat insulating base material 200 is fitted to this part. In addition, the heat insulation foundation material 200 of the number according to the full length of the metal roof material 100 is prepared before this fitting operation. Here, if necessary, part of the heat insulating base material 200 is cut to shorten its length, and the entire length of the metal roofing material 100 and the total length in the longitudinal direction of the heat insulating base material 200 are matched.

  When the fitting operation is performed, the fitting protrusion portion 210h of the convex portion 210 of the heat insulating foundation material 200 is fitted in the central haze portion 110h of the metal roofing material 100. At the same time, the fitting projection 232 h of the one-end-side projection 232 of the heat insulating base material 200 is fitted in the lower gouged portion 132 h of the metal roofing material 100. Further, the other end side convex portion 231 of the heat insulating base material 200 is firmly abutted on the inner side surface of the inclined portion in the vicinity of the upper goug portion 131 h of the metal roofing material 100. The above assembly work is performed by using the flexibility of the metal roofing material 100 and the elasticity of the heat insulating base material 200 well.

  In performing this work, metal roof material 100 has upper gouged part 131h and lower gouged part 132h having different bending shapes, and the shape of both ends in the width direction of heat insulation base sheet 200 is also different correspondingly. When assembling the metal roofing material 100 and the heat insulation base material 200, it carries out, confirming this.

  Subsequently, a procedure for attaching the folded sheet roofing material 1 in which the metal roofing material 100 and the heat insulating base material 200 are combined to the main building 50 will be described. FIG. 9 is an enlarged perspective view showing a connecting portion of the folded sheet roof material 1 shown in FIG. Moreover, FIG. 10 is a perspective view which shows the state which partially attached the folded-plate roof material 1 shown in FIG. 1 to the roof building 50. Moreover, FIG. 11 is explanatory drawing which shows the connection method of folding board roof materials.

  The folded sheet roofing material 1 is placed on the main building 50 in accordance with the standard color of the main building 50.

Specifically, the mutual strength of the fixed support member and the folded plate roofing material is combined, and the heat insulating material is accumulated even if a large amount of snow is deposited, for example, by snow accumulation in the region of the folded plate roofing material between the fixed supporting members. There is no chance to crush. As a result, no gap is generated at the connection between the folded sheet roofing materials, water leakage from the ceiling due to the intrusion of rain water into the building, or a gap is generated at the overlapping part of the folded sheet roofing material main bodies. May be damaged under the influence of severe weather conditions such as strong wind accompanying the passing of a typhoon or a low pressure, or downburst due to recent weather changes, or part or all of the folded roofing material may peel off from the roof To prevent

  Moreover, since the number of parts required for construction of a folding plate roof material can be restrained according to the above-mentioned structure, it can lead to the cost reduction of the component price of the whole folding plate roof material.

  As a second advantage, as is apparent from the direction of application of the folded sheet roofing material described above, the point is that it is easy to apply the folded sheet roofing material. Even if you are not an experienced installer like a so-called roofer who is required for the construction of a conventional folded sheet roofing material, a constant quality folded sheet roofing material with excellent water leakage resistance and durability. It becomes possible to construct. Moreover, since the construction procedure is simple, the construction work of the folded sheet roofing material can be completed in a short time. Thus, the construction cost can be reduced, and the construction work can be completed promptly as scheduled without being influenced by the weather even in irregular weather seasons. As a result, there is no possibility of delaying the construction schedule of the construction work of a convenience store or the like whose opening date and time is determined in advance and the opening date and time is displayed during construction.
