Therefore, sunlight is extracted from the top light 14 inside the building.

[Shading structure]
Here, in the present embodiment, by taking an example of a repair work on an existing roof, the toplight 14 is shielded from light, so that sunlight is suppressed from being indoors. FIG. 1 is a perspective view showing a main part of a gantry 40 applied to this embodiment.

As shown in FIG. 1, the gantry 40 according to the present embodiment uses two gantry members 42 as an example. The gantry member 42 includes a pillar portion 44 and a crosspiece portion 46. The crosspiece 46 of the gantry member 42 is made of equilateral angle steel (angle material) having a predetermined length. One outer surface of the crosspiece 46 is a support surface 48 and the other outer surface is an adjustment surface 50. In the crosspiece 46, one end side in the width direction of the support surface 48 and the adjustment surface 50 is connected to each other. The longitudinal section is formed in a substantially L shape.

A long hole 52 as a long hole portion is formed through the adjustment surface 50 of the crosspiece 46, and the long hole 52 has a long axis in the longitudinal direction of the adjustment surface 50 at an intermediate portion in the width direction of the adjustment surface 50. It is formed along the direction. As a result, the two crosspieces 46 face each other with the adjustment surfaces 50 so that their support surfaces 48 are flush with each other, so that at least a part of the elongated holes 52 of each adjustment surface 50 overlap. Is possible.

A mounting portion 54 is formed on one end side of the column portion 44 in the longitudinal direction. The mounting portion 54 is formed in a rectangular frame shape in a side view, and is provided so as to project on the crosspiece portion 46 side of the column portion 44. .. For example, a strip-shaped plate material made of a steel plate is used for the column portion 44, and one end side in the longitudinal direction of the strip-shaped plate material can be easily formed by bending it into a rectangular frame shape. For example, a strip-shaped plate material having a width wider than the width dimension of the support surface 48 of the crosspiece portion 46 is used for the support column portion 44, and one end portion of the strip-shaped plate material is bent (bent) into a substantially U-shape and further bent. By bending the tip side inward, a cross section is formed into a substantially rectangular frame shape that is long in the up-down direction (longitudinal direction of the column portion 44).

In the column portion 44, the tip end surface (the surface on the longitudinal direction side) of the mounting portion 54 is the mounting surface 54A, and the lower surface (the side opposite to the mounting surface 54A) of the mounting portion 54 is the contact surface 54B. There is. In the column portion 44, at one end side in the longitudinal direction of the crosspiece portion 46, the attachment surface 54A of the attachment portion 54 is in contact with the surface of the crosspiece portion 46 opposite to the support surface 48 (the surface on the back side of the support surface 48). The surface of the crosspiece portion 46 opposite to the adjustment surface 50 is brought into contact with the side portion of the attachment portion 54, and the crosspiece portion 46 is joined by welding or the like. As a result, the gantry member 42 is formed in a substantially L-shape by joining the supporting column portion 44 and the crosspiece portion 46 at a substantially right angle when viewed from the side (for example, the adjustment surface 50 side). In addition, in the mounting portion 54 of the column portion 44, the contact surface 54</b>B is provided so as to project outward in the width direction of the adjusting surface 50 of the crosspiece portion 46, that is, on the opposite side of the crosspiece portion 46 from the support surface 48.

In the gantry 40, one of the two gantry members 42 is turned over so that the pillars 44 are separated from each other, and the tip ends of the crosspieces 46 are arranged so as to face each other, and the adjustment surfaces of the crosspieces 46 are arranged. 50 are opposed to each other. As a result, in the gantry 40, the pillar portions 44 are arranged in pairs on both sides in the longitudinal direction of the bar portion 46 in which the two are integrated, and the adjustment surfaces 50 are relatively moved in the longitudinal direction of the bar portion 46. The distance between the pair of support columns 44 can be changed. Further, in the gantry 40, at least two bolts 56 are inserted into each elongated hole 52 of the adjustment surface 50, and a nut 58 is screwed into each of the bolts 56, so that the crosspieces 46 are fastened and fixed to each other. Thus, the pair of gantry members 42 are connected. Note that the two mount members 42 may have different lengths of the crosspiece 46, for example.

In the gantry 40, a pair of support columns 44 are provided on both sides of the toplight 14 in the width direction, and the crosspieces 46 are arranged so as to straddle the toplight 14. Further, in the gantry 40, the overlapping margin of the crosspieces 46 is adjusted so that each of the pillars 44 is brought into contact with the frame body 22 (outer frame 26) of the toplight 14, and the length of the crosspiece 46 as a whole is adjusted. As a result, the distance between the pair of support columns 44 is adjusted.

In the gantry 40 in which the distance between the pair of supporting columns 44 is adjusted, the contact surface 54B of the mounting portion 54 of the supporting column 44 is brought into contact with the upper surface of the fitting B of the outer frame 26 (the peripheral edge of the top light 14). It is arranged on the body 22, and each of the support columns 44 is fastened and fixed to the frame body 22 (for example, the inner frame 24) by using, for example, screws 60. As a result, the gantry 40 is fixedly installed on the frame body 22 with the support surface 48 of the crosspiece portion 46 facing upward. Further, since the contact surface 54B of the mounting portion 54 of the support column portion 44 is projected outward in the width direction of the adjustment surface 50, the frame 40 of the gantry 40 does not interfere with the frame body 22 and the glass plate 28. To be prevented. In addition, when there is a step between the inner frame 24 and the outer frame 26, a recessed portion 44A that is convex toward the inner frame 24 is formed in the column portion 44, and the screw 60 is screwed into the recessed portion 44A. It is preferable.

Further, a plurality of the gantry 40 are fixed to the longitudinal direction of the top light 14 at a predetermined interval, and a plurality of gantry 40 are attached to the frame 22 and arranged. The mounting intervals of the gantry 40 may be set according to the width of the frame 22 and the weight of the light-shielding roof panel 62 described below.

In the light-shielding structure of the present embodiment, the light-shielding roof panel 62 as a light-shielding roof material is used, and the light-shielding roof panel 62 is placed across a plurality of mounts 40. As the light-shielding roof panel 62, it is preferable to use a general commercially available product that can be cut and can be connected in plural in the width direction and the length direction. Further, the light-shielding roof panel 62 is preferably made of a member that can withstand wind and rain such as ZAM (a registered trademark of hot dip galvanized aluminum-magnesium alloy plated steel sheet) or hot dip galvanized material on the surface. As a result, the light-shielding roof panel 62 is easy to change the installation area and has excellent weather resistance.

In the light-shielding roof panel 62, a heat insulating material 68 is arranged between a front plate 64 and a back plate 66. Further, in the light-shielding roof panel 62, substantially trapezoidal convex portions 64A are formed on the front plate 64 at predetermined intervals in the width direction, and a substantially trapezoidal concave portion 66A is formed on the back plate 66. Is formed on the lower side of each of the protrusions 64A. The surface shape of the light-shielding roof panel 62 is preferably a shape that takes into consideration the shape of the roof material of the roof 10, and this can prevent the light-shielding roof panel 62 from impairing the aesthetic appearance of the roof 10.

The light-shielding roof panel 62 is installed on the roof 10 with the longitudinal direction (direction intersecting the arrangement direction of the convex portions 64A) being the longitudinal direction of the folded plate 12. In addition, the light-shielding roof panel 62 has a size that covers the frame body 22 of the top light 14 and integrally covers each of the gantry 40 (a size in which a peripheral edge portion protrudes to the outside of the frame body 22, an installation area). Are arranged so as to straddle each of the mounts 40.

The back plate 66 of the light-shielding roof panel 62 is supported by the pedestal 40 with the back plate 66 being in contact with the support surface 48 of the crosspiece 46. Further, the light-shielding roof panel 62 is inserted from the convex portion 64A, and the mounting screw 60A penetrating into the concave portion 66A is screwed from the support surface 48 to the crosspiece portion 46, so that it is fastened and fixed to each of the gantry 40. As a result, the light-shielding roof panel 62 covers the upper side of the top light 14, suppresses the sunlight from shining on the glass plate 28 of the top light 14, and the sun light is injected from the top light 14 into the interior of the building. Suppress it.

In this embodiment having such a configuration, the two gantry members 42 are used for the gantry 40. Since the gantry member 42 has a simple L-shape by the support 44 and the crosspiece 46, it can be easily manufactured at low cost. Further, the two gantry members 42 can adjust the distance between the pair of support columns 44 by relatively moving the adjustment surface 50 in the longitudinal direction of the crosspiece 46 with the adjustment surfaces 50 of the crosspiece 46 facing each other. In addition, since the gantry member 42 has the elongated hole 52 formed in the adjusting surface 50 of the crosspiece 46, the two gantry members 42 can be easily fastened and fixed by the bolts 56 and the nuts 58 at arbitrary positions in the longitudinal direction. Can be joined together.

Generally, in order to manufacture a pedestal for mounting a light shielding roof material for shielding the top light 14, it is necessary to visit a store in advance and go up to the roof 10 to measure the top light 14. In addition, the pedestal needs to be accurately manufactured based on the measurement result.

On the other hand, in the gantry 40, by using the two gantry members 42, it is possible to adjust the distance between the pair of support columns 44 in a so-called on-site setting, so that it is not necessary to perform the measurement work of the toplight 14 in advance. For this reason, it is not necessary to visit the store prior to the work and perform the work such as measuring on the roof 10 and the number of work steps can be reduced. Moreover, since the gantry member 42 used for the gantry 40 has a simple structure in which the pillar portion 44 and the crosspiece portion 46 are joined, it can be easily manufactured.

Further, since the installation of the gantry 40 and the installation of the light-shielding roof panel 62 are performed only on the roof 10 of the store, it is not necessary to carry out curing such as moving the products displayed in the store. The work for shielding the top light 14 does not affect the sales of the store. Moreover, since the sunlight from the top light 14 is blocked, it is possible to prevent the products in the store from being damaged due to the influence of heat and sunlight, and to suppress the reduction of the air conditioning efficiency in the store.

Further, since the abutment surface 54B of the lower surface of the mounting portion 54 is abutted on the frame body 22 of the toplight 14 of the support part 44 of the gantry 40, the light shielding roof panel 62 is attached to the frame body 22 of the toplight 14. Can be easily positioned. This facilitates the adjustment of the gap between the top light 14 (glass plate 28) and the light-shielding roof panel 62, and thus facilitates the attachment of the light-shielding roof panel 62 to the roof 10 at an appropriate position. Moreover, in the gantry member 42, the contact surface 54</b>B of the mounting portion 54 of the column portion 44 is projected below the crosspiece portion 46. Therefore, in the gantry 40, not only the gantry member 42 but also the light-shielding roof panel 62 is separated from the glass plate 28 of the top light 14, so that the gantry member 42 and the like come into contact with the glass plate 28 and cause damage or the like. Can be effectively prevented.

Further, when the gantry 40 and the light-shielding roof panel 62 are installed, the frame 22 of the existing toplight 14 is not disassembled or refurbished (remodeled), so that the appearance of the toplight 14 seen from the inside can be maintained. It is possible to reduce the working cost. Moreover, the existing waterproof function can be used, and the work of attaching the light-shielding roof panel 62 and the waterproofing process are facilitated.

Further, since the heat insulating material 68 is provided on the light-shielding roof panel 62, even if the light-shielding roof panel 62 receives the heat of sunlight, the heat of the light-shielding roof panel 62 can be suppressed from being transmitted from the top light 14 to the interior. Therefore, the heat insulating property can be further improved. As a result, it is possible to further suppress a decrease in indoor air conditioning efficiency. Further, in the gantry 40, only the lower ends of the support columns 44 on both sides of the crosspiece 46 in the longitudinal direction are fixed to the frame body 22. Therefore, the top light 14 can be reproduced on the roof 10 by a simple work of removing the light-shielding roof panel 62 from each of the gantry 40 and removing each of the pillar portions 44 of the gantry 40 from the frame body 22, and the indoor lighting can be obtained. Will be possible.

In addition, in this embodiment described above, the toplight 14 formed in the roof 10 in a rectangular shape in plan view has been described as an example. However, the lighting unit is not limited to the rectangular shape in plan view, and may have an L-shape or a shape in which the rectangular shape is connected so as to circulate.

FIG. 5 is a plan view schematically showing a top light 70 as a modified example of the daylighting section of the present embodiment.
As shown in FIG. 5, the top light 70 has a shape in which a top light portion (top light) 72 and a top light portion (top light) 74 each formed in a rectangular shape are continuous. The frame body 76 of the top light 70 has a shape in which the frame body 72A of the top light portion 72 and the frame body 74A of the top light portion 74 are connected and integrated at one side in each longitudinal direction. Thereby, the top light 70 is formed in a substantially L shape in a plan view.

The gantry 40 is bridged in the width direction of the frame body 72A on the side of the top light portion 72, and a plurality of pedestals 40 are arranged in the longitudinal direction of the frame body 72A of the top light portion 72. Further, the gantry 40 is bridged in the width direction of the frame body 74A on the side of the top light portion 74, and a plurality of pedestals 40 are arranged in the longitudinal direction of the frame body 74A of the top light portion 74.

A plurality of the light-shielding roof panels 62 are connected to each other in the longitudinal direction and the width direction to have a substantially L shape in plan view, and are arranged so as to straddle the gantry 40 on the side of the top light part 72 and the gantry 40 on the side of the top light part 74. It is fixedly installed on each of the mounts 40.

Even in such a top light 70, it is possible to easily shield light by using the same pedestal 40 (mounting member 42) as the top light 14. Further, since the work for shading does not require indoor work, the work for shading the top light 70 does not affect the sales of the store.

In the embodiment and the modification described above, the elongated hole 52 is formed in the adjustment surface 50 of the crosspiece 46, and the crosspieces 46 are joined together by the bolt 56 and the nut 58, so that the pair of gantry members 42 are formed. Joined. However, the pair of gantry members may be joined to each other by various joining methods such as welding or screwing the crosspieces.

Further, in the present embodiment and the modified example, the folded plate 12 is described as an example of the roof material, but the roof provided with the lighting portion is not limited to the folded plate 12, and any known roof material may be used. Good. Furthermore, in the present embodiment, the repair work of the existing roof is taken as an example, but it may be applied to the shading of the daylighting portion of the newly constructed roof (for example, shading during a period other than a specific period such as winter).
