Description

  The present invention relates to a heat shield sheet mounting structure fixed and stretched on a roof of a container house.

  This type of container house is mainly movably installed outdoors so as to be used in a field office or a trunk room of a work site. The transportation is done by a trailer.

  Therefore, since the container house is easily exposed to wind and rain and is also susceptible to vibrations, the container house is formed in a strong and wind-resistant structure, such as an earthquake-resistant and wind-resistant structure.

  On the other hand, due to the nature of frequent movement, it is required to have a lightweight, simple, clean shape and structure. It is usual that there is almost no heat.

  As a heat shield measure for a container house, it can be assumed that a heat shield sheet used for corrugated roofs (folded roofs) of various buildings is retrofitted on the roof of the container house. Specifically, for example, in a connecting mountain portion where the ends of corrugated roof materials are connected, a fixing tool is attached to a bolt body or a goby portion protruding upward for connecting the roof material, Then, a groove-shaped frame for laying the seat is laid on the roof, and a heat shield sheet is attached to the groove-shaped frame (see, for example, Patent Document 1).

JP 2010-112007 A

  However, since the bolt body and the goby portion do not protrude on the roof of the container house, it is impossible to attach the fixture, and it is difficult to construct the grooved frame. Therefore, the heat shield sheet mounting structure for the corrugated roof cannot be applied to the roof of the container house as it is.

  The present invention has been proposed in view of such circumstances, and an object of the present invention is to provide a heat shield sheet mounting structure that allows a heat shield sheet to be easily and securely attached to the roof of a container house. is there. In particular, the purpose of making it possible to use a grooved frame that has been conventionally used is also included.

  In order to achieve the above object, the heat shield sheet mounting structure according to claim 1 is characterized in that a sheet extending frame is installed on the roof of a container house, and the heat insulating sheet is fixed and extended by the sheet extending frame. The heat shield sheet mounting structure has a fixture that is formed by bending a plate body, and includes a mounting base portion for mounting the seat extending frame and a base portion fixed to the roof of the container house. The base portion of the fixture is fixed to the roof of the container house, and a draining cover is disposed thereon, and a seat extension frame is installed on the installation table portion. It has a structure in which the heat shield sheet is fixed.

  According to the mounting structure of the heat shield sheet according to claim 1, it is a structure using a fixture including an erection base part for erection of the sheet extending frame and a base part fixed to the roof of the container house. Therefore, the sheet extending frame can be reliably installed on the roof, and as a result, the heat shield sheet can be easily installed in the container house. Moreover, since this fixture is formed by bending a plate, its manufacture can be performed easily.

  In particular, if a grooved frame that has been conventionally used as a mounting structure for a corrugated roof heat shield sheet is used as the seat tension frame, the heat shield sheet can be attached more easily and reliably. In addition, the cost can be reduced if conventional products are used.

  In addition, since the base portion of the fixture is fixed to the roof of the container house and the drainage cover is disposed thereon, it is possible to reliably prevent water from entering the container house.

  As shown in FIGS. 1 and 3, the heat shield sheet 10 is attached to the roof of the container house 1 used in a field office, a trunk room, or the like at the work site.

  The frame of this container house 1 is a structure in which pillars and beams are joined, large beams are arranged at both ends of the roof, small beams are erected between them, and roofing material is wound on them. ing. As shown in FIG. 1, the large beam protrudes slightly from the roof surface to form an end protrusion 1 a.

  The heat shield sheet mounting structure of the present embodiment is such that the heat shield sheet 10 is fixed and stretched to a seat stretch frame 30 that is constructed and fixed on the roof. A structure having a fixture 20 formed by bending a belt-like plate body made of metal, synthetic resin, or the like, which includes an erection base portion 22 to be erected and a base portion 21 fixed to the roof of the container house 1; (See FIG. 2). As shown in FIG. 1, the base portion 21 of the fixture 20 is fixed to the roof surface of the container house 1. In addition, the base part 21 should just match | combine the edge part outline shape of a roof, Therefore, it is not limited to a fall L shape.

  The base portion 21 is formed in an inverted L shape that matches the outline shape of the end protruding portion 1a of the roof, and the installation base portion 22 is bent and connected from the lower end of the vertical piece 21b of the base portion 21, and the mounting piece 22a, the upright piece 22b, and the installation piece 22c are formed in a U-shape.

  The base 20 of the fixture 20 is fitted and attached to the end protrusion 1a, and is fixed to the end protrusion 1a by screws with a horizontal piece 21a and fixed to the roof. A draining cover 2 is placed on the upper surface of the horizontal piece 21a that is screwed so as to cover the screw fixing part, and one end of the draining cover 2 is bent toward the mounting piece 22a side of the adjacent erection base part 22. The other end protruding outward of the container house 1 is bent and fixed so as to contact the side surface of the container house 1.

  A seat tension frame 30 is fixed and installed on the installation piece 22c of the installation table 22 with screws, and the heat shield sheet 10 is fixed to the sheet extension frame 30.

  As shown in FIG. 4, the fixture 20 is attached at appropriate positions at both ends of the container house 1, and is configured to support a long sheet stretching frame 30 with a plurality of fixtures 20, 20. ing.

  On the other hand, the seat tension frame 30 is formed of a concave groove body made of metal or a hard synthetic resin (for example, FRP), and a reinforced lip portion 34 formed by winding is formed at an opening end portion of the groove portion 31. .

  In this embodiment, in order to stretch and fix the heat shield sheet 10 using the sheet stretch frame 30, in this embodiment, a sheet using a known groove-shaped frame used for installing the heat shield sheet 10 on the corrugated roof. In addition to the seat tension frame 30, the tension structure is adopted, an inner frame 51 having the same shape as the seat tension frame 30, a rectangular stopper 52 with rounded corners, and a long shape The wave spring 53 and the frame cover 40 that closes the opening of the groove 31 are used. At both ends in the width direction of the frame cover 40, pressing pieces 42 and 42 for pressing the heat shield sheet 10 are formed.

  On the other hand, the heat shield sheet 10 is made of a synthetic resin sheet that has flexibility and stretchability and reflects solar heat, solar rays, and the like. For example, as shown in the present embodiment, the heat shield sheet 10 reflects solar heat, solar rays, and the like. A woven fabric sheet formed by knitting a resin yarn material colored in silver or the like vertically and horizontally can be suitably used.

  The heat shield sheet 10 is fixed to a sheet extending frame 30 fixed on the roof, and is extended between the sheet extending frames 30 and 30 installed on both ends of the container house 1. In the present embodiment, the heat shield sheet 10 that is long in a band shape in a direction orthogonal to the sheet stretching frame 30 is used. In addition, as shown in FIG. 4, the heat shielding sheet 10 used in this embodiment is knitted with vertical and horizontal resin yarn materials except for both ends in the width direction (portions indicated by cross-hatching). However, at both ends, the resin yarn material (weft yarn 10a) is not fixed with the warp yarn 10b (see an enlarged partial plan view surrounded by a one-dot chain line in FIG. 4). That is, the both end portions constitute an insertion portion 11 through which a shaft portion of a bolt or a screw can be inserted.

  Next, a procedure for fixing and stretching the heat shield sheet 10 using the sheet stretching frame 30 will be described.

  First, the inner frame 51 is mounted in the groove portion 31 of the seat extending frame 30 so as to sandwich the heat shield sheet 10 between the bottom portion 32 (the inner bottom surface thereof), and an appropriate place on the bottom surface 51a of the inner frame 51 is mounted. The heat shield sheet 10 is fixed by fitting the stopper 52 into the sheet. The stopper 52 has a long side that is equal to or slightly larger than the width dimension (inner dimension) of the groove portion 31 of the seat tension frame 30 and is inserted into the inner bottom surface with the long side facing the longitudinal direction of the groove. If the central groove 52a is rotated with a screwdriver or the like, it is press-fitted into the groove 31. In this way, the inner frame 51 is pressed against the side wall 33 of the groove portion 31 with the heat shield sheet 10 interposed therebetween, and is temporarily fixed.

  After the heat shield sheet 10 is temporarily fixed in this manner, the wave spring 53 is further mounted in the groove 31 so that the crest 53a and the trough 53b press the side wall 33 of the groove 31 from the inside. The wave spring 53 is formed such that the width dimension (twice the amplitude) from the peak part 53a to the valley part 53b is larger than the width dimension (inner dimension) of the bottom part 32 of the groove part 31, and is housed in the groove part 31. Thus, an elastic restoring force acts to further press the inner frame 51 toward the side wall 33 of the groove 31.

  After the heat shield sheet 10 is fixed to the sheet stretching frame 30 by pressing from the inside of the groove portion 31 in this way, the frame cover 40 is covered so as to hide the opening of the groove portion 31, and the sheet is covered with a screw S (drill screw or the like). Fix to the tension frame 30.

  In the present embodiment, the sheet extending frame 30 is arranged at both ends of the container house 1 and is configured to fix the end portions of the heat shield sheet 10, so that measures for preventing the heat shield sheet 10 from coming off are taken. Although it is necessary to ensure, since the heat shield sheet 10 is firmly fixed to the sheet stretching frame 30 using various members as described above, there is no possibility that the heat shield sheet 10 is detached.

  In this embodiment, as described above, a known sheet stretching structure is adopted as the sheet stretching structure, but other sheet stretching structures as shown in FIG. 5 may be used.

  The seat tensioning structure using the seat tensioning frame 30 shown in FIG. 5 does not use the inner frame 51, the stopper 52, and the wave spring 53 (see FIGS. 1 and 3 above), and is attached to the lower surface of the frame cover 40. The heat insulating sheet 10 can be fixed by fitting the set of provided fitting pieces 41, 41 into the groove 31 of the seat tension frame 30 with the heat insulating sheet 10 interposed therebetween. It is desirable that the set of fitting pieces 41, 41 have a size that allows press fitting with the opening of the groove portion 31. In addition, although one set of this fitting piece 41 is formed via the space in the center part, it is good also as an integral protrusion piece, without providing space. For example, only the protruding piece may be an elastic body and formed by two-color molding.

  Further, the seat tension frame 30 and the frame cover 40 can be fixed by bolts B and nuts N. In this example, the bolt heads are arranged below, and the seat tension frame 30 is provided. The rotation of the bolt B is stopped by a bolt detent projection piece 36 provided on the lower surface of the bottom portion 32, and the upper nut N can be turned and fixed easily.

  According to the configuration shown in FIG. 5, the heat shield sheet 10 can be fixed and stretched by the seat stretching frame 30 and the frame cover 40 without using the inner frame 51, the stopper 52, the wave spring 53 and the like. Therefore, the heat shield sheet 10 can be attached to the container house 1 more easily and at a lower cost. All or some of the inner frame 51, the stopper 52, and the wave spring 53 may be used in combination.

  The fixing and tensioning structure of the heat shield sheet 10 is not limited to the above two types, and other structures may be used. Any structure using at least the sheet tensioning frame 30 may be used. May be.

  In the example of the two types of seat tension frames 30 (seat tension structure) shown above, the seat tension frame 30 and the frame cover 40 are fixed with screws S or bolts B and nuts N. Since the shaft portion passes through the insertion portion 11 of the heat shield sheet 10, the heat shield sheet 10 is not damaged by screws and bolts. In the case of screwing, the screw S may be inserted through a part other than the insertion part 11.

  According to the heat shield sheet mounting structure described above, since the fixture 20 including the installation base portion 22 and the base portion 21 is used, the base portion 21 can reliably fix the fixture 20 to the roof. Since the seat extending frame 30 is disposed on the installation base portion 22 of the fixture 20, the heat shield sheet 10 can be easily and reliably fixed on the roof of the container house 1.

  In particular, if a groove-shaped frame that has been conventionally used as a mounting structure for a heat shield sheet of a corrugated roof is used as the seat stretching frame 30, it can be more easily and reliably attached. Use of conventional products also leads to cost reduction.

  Moreover, since the draining cover 2 is arranged on the base part 21, it is possible to prevent water from entering the room of the container house 1 through the fixing part by screwing. In the above embodiment, the base portion 21 is screwed to the roof, but other fixing means, for example, fixing with an adhesive may be used.
