Description

  The present invention relates to a seat for preventing a temperature rise of a roof attached to the uppermost part of a building in order to block direct sunlight or the like.

  Since the building's roof is exposed to direct sunlight, the temperature of members constituting the roof rises, and the indoor temperature rises accordingly. In particular, in a building having a simple structure in which a heat insulating material is not installed on the roof or a building without an attic, when the roof is exposed to direct sunlight, the indoor temperature is remarkably increased.

  When the temperature in the room rises greatly, it is necessary to operate the cooling device or the like to lower the temperature, which is not preferable from the viewpoint of cost such as electricity costs and environmental load. For this reason, various contrivances have conventionally been made for measures against heat. For example, a double roof is used to improve the heat insulation performance of the roof, or a sprinkler is installed to forcibly cool the roof.

Patent Document 1 below discloses that a sheet is installed on the roof with a gap from the roof. Further, in order to improve the ventilation of the space between the roof and the sheet, or to prevent damage due to the sheet floating when the wind is strong, a plurality of through holes are provided in the sheet.

  However, it is costly to double the roof or install a sprinkler, and the roof becomes heavy, which causes structural problems.

  In addition, when a sheet provided with a plurality of through holes is installed on the roof as in Patent Document 1, sufficient ventilation can not be secured with only a small hole, and in the case of strong sunlight, the roof and the sheet The heat builds up between the roof and the temperature of the roof rises, or the wind blown between the roof and the seat does not come out enough in a strong wind, and the seat rises and breaks. Problems may arise.

  The present invention has been made to solve the above-described problems, and is a roof sheet that is installed on a roof to prevent a rise in temperature, and the ventilation of the space between the sheet and the roof is sufficient. An object of the present invention is to provide a roof sheet that can be secured.

  In order to solve the above problems, a roof sheet according to the present invention has a plurality of slits formed in parallel in the roof sheet installed on the roof so that direct sunlight does not hit the roof of the building. A light-shielding sheet portion, and a member that is fixed to the roof, and a sheet stopper that installs the light-shielding sheet portion on the roof by fixing a predetermined portion of the light-shielding sheet portion. It is characterized by.

  According to the roof sheet according to the present invention, sufficient ventilation of the space between the sheet and the roof can be ensured, and the temperature rise of the roof can be sufficiently prevented.

  Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings. FIG. 1 is a diagram showing constituent members constituting the roof sheet according to the present embodiment. As shown in FIG. 1, the roof sheet according to the present embodiment includes a light shielding sheet portion 10 composed of a plurality of sheet pieces 11 and a sheet stopper member 20 for fixing both ends of the sheet pieces 11 to the roof. I have.

  The sheet piece 11 constituting the light shielding sheet portion 10 is formed according to the size and shape of the roof to be installed. For example, the sheet piece 11 is formed by cutting a large sheet into a size of 3 m in length and 30 cm in width. . The sheet piece 11 is a light shielding sheet having a function of blocking direct sunlight, and in this embodiment, a black light shielding sheet made of synthetic resin (high density polyethylene) is used. Further, the sheet piece 11 according to the present embodiment is a mesh sheet in which synthetic resin yarns are woven in order to give the sheet itself a ventilation function.

  As will be described later, the plurality of sheet pieces 11 are arranged in parallel in the length direction, and both end portions in the length direction are fixed to the roof via the sheet stopper member 20. Thus, when the light shielding sheet portion 10 is configured by arranging a plurality of sheet pieces 11 in parallel, slits in the length direction are formed in the sheet portion 10 at regular intervals. If the light shielding sheet has slits, a large amount of wind can be passed between the sheet and the roof through the slits while maintaining the light shielding function.

  As for the installation mode of the sheet piece 11, it is desirable to arrange the sheet pieces 11 in parallel with no gaps as in the present embodiment in consideration of light shielding properties. However, if it is desired to further ensure ventilation in the slits, leave some gaps. You may arrange them.

  The sheet stopper member 20 includes a sheet receiving member 22 and a spring 25. The sheet receiving member 22 is an elongated strip having a concave cross section perpendicular to its extending direction, and both side walls are formed to be inclined inward by about 30 ° with respect to the bottom surface fixed to the roof (described later). See FIG. 3). The sheet receiving member 22 is formed, for example, by bending a metal plate made of steel or the like, or extruding a metal such as aluminum.

  The sheet receiving member 22 is formed with a fixing portion 22a for fixing the sheet receiving member 22 to the roof. The fixing portion 22a is a flat projection protruding laterally from the bottom surface of the sheet receiving member 22, and a small hole for passing a bolt is formed in the vicinity of the center thereof.

  The spring 25 is a wire that functions as an elastic locking member that fixes the end of the sheet piece 11 in the recess of the sheet receiving member 22, and is bent so that peaks and valleys are alternately repeated on the same plane. Therefore, as will be described later, when the spring 25 is narrowed so that the height difference between the peaks and valleys is reduced and inserted into the recess of the sheet receiving member 22, the spring 25 reduces the height difference between the peaks and valleys. Generates elastic force in the direction of increasing the width. Further, the length of the spring 25 is substantially the same as the length of the sheet receiving member 22.

  Then, the installation method of the roof sheet | seat 1 which concerns on this embodiment is demonstrated, referring FIG.2 and FIG.3. FIG. 2 is a diagram illustrating a state in which the sheet receiving member is fixed to the roof according to the present embodiment. FIG. 3 is an enlarged cross-sectional view showing a state in which the end portion of the sheet piece is fixed to the sheet stopper member in the present embodiment. In this embodiment, the case where the roof sheet 1 is installed on the folded plate roof 50 will be described as an example.

  As shown in FIG. 2, first, the sheet receiving member 22 of the sheet fixing member 20 is fixed to the upper surface of the folded plate roof 50. In the present embodiment, the sheet receiving member 22 is attached to the upper surface of the roof 50 using fixtures (bolts and nuts) for attaching the folded plate roof 50 to the structure. Specifically, the sheet receiving member 22 is installed with the bottom side facing down so that the bolt for attaching the folded plate roof 50 to the structure fits into the small hole of the fixing portion 22a of the sheet receiving member 22. And if a nut is attached to a volt | bolt from the fixing | fixed part and it tightens, the sheet | seat receiving member 22 can be fixed to the roof 50. FIG.

  Subsequently, both end portions of the sheet piece 11 are fixed to the sheet stopper member 20 in order. Specifically, the end portion in the length direction of the sheet piece 11 is positioned on the concave portion of the sheet receiving member 22, pushed from above with the spring 25, and pushed into the concave portion together with the spring 25. At this time, the end of the sheet piece 11 is brought out of the recess.

  As shown in FIG. 3, the width direction of the spring 25 inserted in the recess from above the sheet piece 11 with the vicinity of the end of the sheet piece 11 entering the recess of the sheet receiving member 22 (the horizontal direction in the figure). ), The sheet piece 11 is pressed against the inner wall surface of the recess and fixed.

  In this way, when the plurality of sheet pieces 11 are arranged in parallel so as to cover the entire roof 50, the installation of the roof sheet 1 according to the present embodiment is completed. FIG. 4 is a perspective view showing a state in which the roof sheet according to the present embodiment is installed on the folded plate roof.

  As shown in FIG. 4, the light shielding sheet portion 10 is configured by a plurality of sheet pieces 11 arranged in parallel on the roof 50. The boundary between the adjacent sheet pieces 11 functions as a slit of the light shielding sheet portion 10, and the wind can enter and leave the space between the light shielding sheet portion 10 and the roof 50 through this slit. In particular, since the roof sheet 1 according to the present embodiment is installed on the folded plate roof 50, the wind passes through the concave portion of the roof 50 and the wind enters and exits through the slit of the light shielding sheet portion 10, so that The temperature of the roof 50 can also be lowered by air cooling.

  As described above, the roof sheet according to the present embodiment has been described in detail, but according to the present embodiment, since the light shielding sheet portion is installed so as to cover the roof, it is possible to prevent the roof from being directly exposed to sunlight. It is possible to prevent the temperature of the roof from rising and thereby the room temperature in the building from rising.

  In addition, since the light shielding sheet portion of the present embodiment is provided with a large number of slits, wind can enter and leave the space between the light shielding sheet portion and the roof through the slits. Temperature rise can be prevented. In addition, even when a strong wind is blowing due to a typhoon or the like, the wind that has entered between the light-shielding sheet portion and the roof can go out through this slit, so the light-shielding sheet portion rises greatly and breaks. Can also be prevented.

  Further, in the present embodiment, since a mesh sheet having a ventilation function is used for the light shielding sheet portion, ventilation is possible through the sheet itself, so that the space between the roof and the light shielding sheet portion is further ventilated. I can do it well.

  Further, in the present embodiment, the light shielding sheet portion is configured by arranging a plurality of sheet pieces in parallel, and when a part of the sheet piece is damaged, it can be repaired only by replacing the sheet piece. Running costs can also be kept low.

  Although the present embodiment has been described in detail above, the present invention is not limited to the above embodiment, and various modifications can be made without departing from the spirit of the present invention. For example, the material of the member constituting the roof sheet can be appropriately changed. For example, the material of the sheet constituting the light shielding sheet portion is not limited to the synthetic resin, and a natural material may be used. Further, the sheet itself is not limited to a mesh sheet, and may be a nonwoven fabric or the like.

  Moreover, the sheet | seat stop member which fixes a light shielding sheet part with respect to a roof is not limited to the said structure, It cannot be overemphasized that the member of another structure can be employ | adopted suitably as long as it is a member which can fix a sheet | seat.

  For example, in the present embodiment, the one side of the light shielding sheet portion and the other side opposite to the entire side are configured to be fixed by the sheet stopper member. If there is, any portion of the light shielding sheet portion may be fixed. For example, the fixed portions may be provided in a matrix at predetermined intervals. However, it is necessary to fix so that sufficient ventilation can be provided between the light shielding sheet portion and the roof.

  In the above embodiment, since the roof is a folded plate roof, a concave space (ventilation space) is formed even if the light shielding sheet portion is installed on the surface of the roof, but the roof sheet is attached to the roof with a flat surface. In the case of installation, it is desirable to employ a sheet stopper member that can forcibly form a ventilation space by installing the light shielding sheet portion so as to float from the surface of the roof.

  Moreover, in this embodiment, in order to form a slit in the light shielding sheet portion, a plurality of sheet pieces are arranged in parallel, but even if the slit is formed by making a cut in parallel on one sheet good. At this time, in order to ensure ventilation, for example, slits from one end of the sheet to the other end may be formed at intervals of 30 cm. If the interval between the slits is shortened, it is not preferable in terms of light shielding, and if it is longer, it is not preferable in terms of air permeability. Therefore, it is desirable to provide slits at intervals of 20 to 100 cm.

  Moreover, in this embodiment, although the roof sheet | seat was installed on the folded-plate roof, it cannot be overemphasized that the roof sheet | seat which concerns on this invention can be installed in the roof of various structures. For example, the present invention can be applied to a slate roof or a reinforced concrete roof.
