Description

[Technical field]

[0001] The present invention relates to a heat shielding structure provided directly under the roof of a building. [Background technology]

[0002] Conventionally, heat shielding sheets that reflect radiant heat have been used to prevent temperature rises in buildings. For example, the applicant of the present application has proposed a roof exterior structure in which a heat shielding sheet is provided on the roof in Patent Document 1. For the heat shielding structure inside a building, a heat shielding sheet is directly attached to the walls or ceiling of the room with adhesive, screws, or the like, or the heat shielding sheet is fixed with a cable tie, string, or the like via a support bracket attached to the roof base material.

[0003] [Patent Document 1] JP 2015-143467 A Summary of the Invention [Problem to be solved by the invention]

[0004] However, in conventional heat-shielding structures for the inside of buildings, in order to install heat-shielding sheets on the ceiling, it was necessary to set up scaffolding on the entire interior of the building, or to move the entire building by repeatedly going up and down on a work platform. In addition, the work of directly attaching the heat-shielding sheet to the ceiling space was difficult, and since it was directly attached, it was also time-consuming to remove. In addition, when the heat-shielding sheet was fixed with cable ties or strings via support brackets, gaps were created between the heat-shielding sheet and the roof base material, reducing the heat-shielding effect.

[0005] The present invention has been made in consideration of the above circumstances, and aims to provide a heat shielding structure that is easy to install and can block radiant heat from the outside of a building roof from entering the interior of the building. [Means for solving the problem]

[0006] The heat-shielding structure described in claim 1 comprises a pair of rails extending along the roof base material and fixed to opposite sides of the pair of base materials, runners that engage with the rails and can slide freely, and a heat-shielding sheet that is suspended and held on the rails via the runners, wherein the heat-shielding sheet can move along the rails by sliding the runners and is stretched directly beneath the roof.

[0007] The heat-shielding structure described in claim 2 is characterized in that the heat-shielding sheet is rectangular, has runners attached to both sides parallel to the rail, and at least one of the ends perpendicular to the rail is fixed to the base material or the rail.

[0008] The heat insulating structure described in claim 3 is characterized in that it includes a moving mechanism for moving the heat insulating sheet along a rail to taut the heat insulating sheet directly under the roof. Effect of the Invention

[0009] According to the present invention, it is possible to provide a heat shielding structure that can be easily installed and can block radiant heat from the outside of a building roof from entering the interior of the building. [Brief description of the drawings]

[0010] [Figure 1] 1 is an explanatory diagram showing an embodiment of a heat insulating structure according to the present invention. [Diagram 2] FIG. [Diagram 3] FIG. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0011] Hereinafter, the embodiments of the present invention will be described in detail with reference to the drawings. Fig. 1 is a schematic front view partially showing an embodiment of a heat insulating structure according to the present invention. Fig. 2 is a schematic side view partially showing the same embodiment. Fig. 3 is a perspective view showing an installation method of the same embodiment, with the roof and side walls of the building omitted.

[0012] As shown in Figs. 1 to 3, the heat shielding structure 1 according to the present invention is provided on the indoor side directly below the roof R of a building, and includes a rail 10, a runner 20, and a heat shielding sheet 30. The heat shielding structure 1 can be applied directly below the existing roof R of a factory, store, house, etc., or directly below a newly built roof R. Furthermore, the present invention is not limited to the shape, material, etc. of the roof R, and can be applied not only to metal roofs such as folded plate, vertical roofing, and horizontal roofing, which have high thermal conductivity and tend to become hot indoors, but also to roofs made of tiles, slate, etc.

[0013] The rails 10 extend along the base material M of the roof R, and a pair of rails 10 are fixed to both opposing sides of the pair of base materials M. A pair of base materials M does not necessarily mean that there is only one pair of base materials M in a building, but there may be multiple paired base materials M depending on the structure and size of the building, and may be arranged in parallel, for example. In addition, when the base material M is horizontal or inclined relative to the horizontal due to the shape of the roof R, the rails 10 attached to the base material M are also horizontal or inclined along the base material M.

[0014] The base material M of the roof R is, for example, steel frames such as H-beams and square steel, wood, etc. The mounting structure of the rail 10 to the base material M is arbitrary, and the rail 10 may be fixed via a connector C that connects the two, or by screws, adhesives, welding, etc. The material, shape, and length of the rail 10 are not particularly limited. For example, the material is a metal such as aluminum, the shape is one with a slit-shaped opening at the bottom or one with a running lane at the top, and the length is approximately the same as the length of the base material M to be installed in the longitudinal direction, or one that is connected when fixed to have approximately the same length.

[0015] The runner 20 engages with the rail 10 and is slidable. The runner 20 slidably engages with the rail 10, fixes and supports the heat shield sheet 30, and connects the rail 10 and the heat shield sheet 30. The material, shape, and size of the runner 20 are not particularly limited as long as it can engage with the rail 10, slide within or on the rail 10, and hold the heat shield sheet 30. For example, the shape of the runner 20 is such that the upper part thereof is a roller holding part equipped with a roller, and the lower part thereof is a hanging part equipped with a hanging metal fitting, and is made of a material such as a metal such as stainless steel, a resin, or the like.

[0016] The heat shielding sheet 30 is suspended and held on the rail 10 via the runners 20. The heat shielding sheet 30 may have any structure as long as it can reflect radiant heat, but for example, it may be laminated with metal foil such as aluminum foil on both surfaces or one surface, and a sheet made of resin, glass fiber fabric, or the like, placed between or underneath the metal foil. In this case, by making the surface facing the roof out of metal foil, it is possible to suppress radiant heat from the sun, and by making the surface facing the room out of metal foil, it is possible to reflect radiant heat radiated from inside the building and keep the inside of the building warm in winter, etc.

[0017] The size of the heat shielding sheet 30 is approximately the same as the width between the pair of opposing rails 10, and is preferably approximately the same as the longitudinal length of the rails 10, but it may be divided as necessary. For example, by preparing a plurality of heat shielding sheets 30 each having a width of 1.2 m and a length of 40 m in advance and arranging them in parallel or in series, it is possible to cover the entire surface directly below the roof even in the case of a large building.

[0018] The heat shielding sheet 30 can be moved along the rails 10 by sliding the runners 20, and is stretched directly below the roof R. The heat shielding sheet 30 is suspended slidably via the runners 20 on the rails 10 fixed to the base material M of the roof R, and is moved to be stretched directly below the roof R.

[0019] The heat-shielding structure 1 of the present invention can be easily installed by moving the heat-shielding sheet 30 along the rail 10 via the runner 20, and can block radiant heat from the outside of the building roof from entering the interior.

[0020] 3, the heat shielding sheet 30 is a rectangular sheet, with runners 20 attached to both side portions 32, 34 parallel to the rail 10, and at least one of the ends 36, 38 perpendicular to the rail 10 is preferably fixed to the base material M or the rail 10. One or more runners 20 are attached to each of the side portions 32, 34 of the heat shielding sheet 30 depending on the size of the building to which it is to be stretched and the length of the rail 10.

[0021] The present invention may also include a moving mechanism 40 that moves the heat shielding sheet 30 along the rails 10, thereby stretching the heat shielding sheet 30 directly under the roof R. The configuration of the moving mechanism 40 is arbitrary. For example, a string-like member such as a wire can be hung on a pulley attached to the base material M, an end of the string-like member can be fixed to the heat shielding sheet 30, and the movement of the heat shielding sheet 30 can be controlled by pulling the string-like member at hand. In other words, by including the moving mechanism 40, the heat shielding sheet 30 can be moved more easily.

[0022] The heat shielding structure 1 of the present invention will be described below with reference to examples.

[0023] In this embodiment, as shown in Figures 1 to 3, the heat insulating structure 1 is provided directly under a single-shed roof R made of folded plates, and is composed of a rail 10, a runner 20, a heat insulating sheet 30, and a moving mechanism 40. Note that the moving mechanism 40 is not necessarily provided.

[0024] The rail 10 is made of aluminum alloy, has a height of 46 mm and a width of 45 mm, and has a slit-shaped opening of 14 mm at the bottom. The length of the rail 10 is approximately the same as the longitudinal length of the base material M to be installed. The runner 20 is made of stainless steel, and has a roller holding section at its upper part in which two resin rollers with a diameter of 30 mm are connected by an axis. The lower part of the runner 20 has a hanging section having a hanging metal fitting for suspending and holding the heat shield sheet 30, and is attached to both side parts 32, 34 of the heat shield sheet 30 that are parallel to the rail 10.

[0025] The heat shielding sheet 30 is a rectangular sheet of certified non-combustible material laminated in the following order: aluminum foil, resin film, glass fiber fabric, resin film, and aluminum foil. The heat shielding sheet 30 has a width approximately equal to the distance between the pair of rails 10, a length approximately equal to the rails 10, and is pre-sewn to a size sufficient to cover the entire surface directly below the roof. A core material is attached along the leading edges of both ends 36, 38 of the heat shielding sheet 30 that are perpendicular to the rails 10.

[0026] 3, the moving mechanism 40 includes a pulley and a wire, and a pulley is attached to the base material M on the side where the heat shielding sheet 30 is inserted and on the opposite end side, and the wire is hung on the pulley. Then, once the heat shielding sheet 30 has been fed, the wire is connected to the end 36 on the tip side of the heat shielding sheet 30, so that the heat shielding sheet 30 can be moved by pulling the wire at hand.

[0027] Next, a method for installing the heat insulating structure 1 will be described. First, although not shown, a scaffolding is assembled in a generally U-shape along a pair of base members M to which the rails 10 are attached and an insertion-side base member M that connects these members. As shown in Figure 3, multiple clamps, which are connectors C, are fixed at regular intervals to the bottom flange of the base material M of the roof R, which is an H-shaped steel that extends at an angle to the horizontal direction. Rails 10 are attached to the fixed connectors C. This is performed on both opposing sides of a pair of base materials M. Depending on the length of the base material M to which it is attached, multiple rails 10 may be connected together for use.

[0028] The roller holding parts of the runners 20 are inserted into the rails 10 on both opposing sides of the inclined rails 10 from the higher side, and are slid to feed the heat shielding sheet 30 suspended and held by the hanging parts of the runners 20 one after another. Then, the end 36 on the leading end side of the heat shielding sheet 30 reaches the base material M on the end point side opposite the insertion side, and the heat shielding sheet 30 is stretched directly under the roof R.

[0029] 3, when the moving mechanism 40 is provided, the wires of the moving mechanism 40 are attached to the end 36 on the tip side of the fed heat shielding sheet 30. Once all of the heat shielding sheet 30 has been fed, the end 38 on the base end side of the heat shielding sheet 30 is fixed to the base material M on the insertion side. By operating the wires of the moving mechanism 40, the end 36 on the tip side of the heat shielding sheet 30 is pulled, and the heat shielding sheet 30 moves. When the end 36 on the tip side of the heat shielding sheet 30 reaches the base material M on the termination side, the heat shielding sheet 30 is stretched directly beneath the roof R.

[0030] If necessary, the end 36 at the tip side of the heat shielding sheet 30 can be fixed to the base material M or the rail 10, or the end 36 of the heat shielding sheet 30 can be fixed by fixing the wire of the moving member 40. By fixing one or both of the ends 36, 38 of the stretched heat shielding sheet 30, it becomes easier to stretch the heat shielding sheet 30 taut.

[0031] The heat shielding structure 1 according to this embodiment can be easily installed and removed by setting up a minimum amount of scaffolding and moving the heat shielding sheet 30, which has been adjusted to an appropriate size in advance, along the rails 10. In addition, by reducing the gap between the base material M and the heat shielding sheet 30, it is possible to block radiant heat from the outside of the roof R of the building from entering the interior. In addition, the moving mechanism 40 allows the heat shielding sheet 30 to be moved and fixed more easily.

[0032] The present invention allows various embodiments and modifications without departing from the broad spirit and scope of the present invention. The above-described embodiments are for the purpose of explaining the present invention and do not limit the scope of the present invention. That is, the scope of the present invention is indicated by the claims, not the embodiments. Various modifications made within the scope of the claims and the scope of the invention equivalent thereto are considered to be within the scope of the present invention. [Industrial Applicability]
