Problems to be Solved by the Invention

[0005] However, although the mesh sheet described in Patent Document 1 has a configuration in which the skirt covers the gaps between the sheets, the skirt is not securely fixed to the sheet or the scaffold structure, and there is a risk of being turned up unintentionally during work. As a result, a gap may occur in this part, and there is a risk that construction materials, tools, etc. may jump out to the outside and fall. [Means for solving the problem]

[0006] To solve the above problems, the present invention provides a construction sheet to be installed on temporary scaffolding, comprising a rectangular sheet body formed to be long in the vertical direction, and a vertically elongated strip-shaped portion provided along one side edge of the sheet body, wherein a plurality of grommets are provided on the peripheral edge of the sheet body, a plurality of grommets are provided in the vertical direction on the vertically elongated strip-shaped portion, and the grommets on the left and right side edges of the sheet body and the grommets on the vertically elongated strip-shaped portion are arranged at the same position in the vertical direction.

[0007] The above-described construction sheet is characterized by having a horizontally elongated strip portion provided along the lower edge of the sheet body, with a plurality of grommets provided in the horizontal direction on the horizontally elongated strip portion, and the grommets on the upper and lower edges of the sheet body, as well as the grommets on the horizontally elongated strip portion, being arranged at the same position in the horizontal direction.

[0008] In the above-described construction sheet, the elongated strip portion is separate from the sheet body, and the side edges of the elongated strip portion are arranged overlapping the back side of the sheet body.

[0009] In the above-described construction sheet, the horizontal strip portion is separate from the sheet body, and the side edges of the horizontal strip portion are superimposed on the back side of the sheet body.

[0010] Furthermore, the sheet set according to the present invention comprises the above-mentioned construction sheet and an attachment sheet to be attached to the construction sheet, wherein the attachment sheet has the same length as the vertically elongated strip and comprises a first overlapping strip that is superimposed on the vertically elongated strip and a second overlapping strip that is provided along the side edge of the first overlapping strip and superimposed on the other side edge of the sheet body, wherein the vertically elongated strip and the first overlapping strip are provided with attachment and detachment means, and the second overlapping strip is provided with a plurality of grommets at the same position in the vertical direction as each grommet on the other side edge, and the attachment sheet is positioned between one of the construction sheets and another construction sheet that are arranged perpendicular to each other, and is provided so as to cover the scaffolding support columns present in the perpendicularly arranged section.

[0011] In the above-described sheet set, the first overlapping strip portion and the second overlapping strip portion are separate entities, and the second overlapping strip portion is arranged overlapping on the back side of the side edge portion of the first overlapping strip portion. [Effects of the Invention]

[0012] This invention prevents falling objects from flying out by covering the seams of adjacent construction sheets with a vertically elongated strip. Since the vertically elongated strip is equipped with grommets, it is fixed to the sheet while covering the seam. Therefore, the vertically elongated strip does not peel up, and the seams between sheets are reliably covered. [Brief explanation of the drawing]

[Figure 4]Schematic plan showing the installation method of sheet sets at the corners of temporary scaffolding. [Modes for carrying out the invention]

[0014] Hereinafter, a seat set according to an embodiment of the present invention will be described based on the drawings.

[0015] As shown in Figures 1 and 2, the sheet set 100 according to this embodiment comprises a construction sheet 110 and an attachment sheet 150. The construction sheet 110 is a flexible surface member that is stretched over the outer surface of temporary scaffolding during new construction, renovation, or demolition work of buildings, etc. The construction sheet 110 of this embodiment comprises a sheet body portion 112, a vertically elongated strip portion 114, and a horizontally elongated strip portion 116.

[0016] The sheet body 112 is a rectangular member formed to be long in the vertical direction, and is the main part that performs the shielding function of preventing the scattering of building materials, tools, etc. The sheet body 112 is made of, for example, a mesh sheet made of synthetic resin, and is made to have a predetermined strength while ensuring adequate ventilation. Multiple grommets 118 are provided on the peripheral edges (upper edge, lower edge, left edge, and right edge) of the sheet body 112. Using these grommets 118, the construction sheet 110 is tied to the scaffolding posts and horizontal members, etc., and fixed to the outer perimeter of the temporary scaffolding. In this embodiment, the width of the sheet body 112 is 1.8m, the length of the sheet body 112 is 7.2m, and the pitch of the grommets 118 is 450mm, but it is not limited to these dimensions, and for example, dimensions specified in the JIS A 8952 standard can be adopted.

[0017] The elongated strip portion 114 is a strip-shaped member provided to extend vertically along the left edge of the sheet body portion 112. The elongated strip portion 114 is a separate member from the sheet body portion 112, with its right edge overlapping the back side of the left edge of the sheet body portion 112 and attached by sewing or the like. The material forming the elongated strip portion 114 may be the same material as the sheet body portion 112, or it may be a different material. The elongated strip portion 114 is provided with a plurality of eyelets 120 along the vertical direction. Each of these eyelets 120 is provided at the same position in the vertical direction (up and down direction) as the eyelets 118 provided on the left and right edges of the sheet body portion 112. In addition, a plurality of attachment and detachment means 122 are provided on the surface side of the elongated strip portion 114 along the vertical direction. In this embodiment, the fastening means 122 is a female snap button, but it may also be a hook-and-loop fastener, a magnet, or a thread used for tabi socks.

[0018] The horizontally elongated strip portion 116 is a strip-shaped member provided to extend horizontally along the lower edge of the sheet body portion 112. The horizontally elongated strip portion 116 is a separate member from the sheet body portion 112, and its upper edge is placed on the back side of the lower edge of the sheet body portion 112, and it is attached by sewing or the like. The material forming the horizontally elongated strip portion 116 may be the same material as the sheet body portion 112, or it may be a different material. Here, the horizontally elongated strip portion 116 is provided with a plurality of eyelets 124 along the horizontal direction. Each of these eyelets 124 is provided at the same position in the horizontal direction (left-right direction) as each eyelet 118 provided on the lower edge of the sheet body portion 112.

[0019] The attachment sheet 150 is a strip-shaped sheet provided at the joint portion between the construction sheets 110, particularly between the construction sheets 110 arranged orthogonally to each other. This attachment sheet 150 has a function of preventing building materials, tools, etc. from protruding outward and falling from the joint portion by covering the vertical support columns existing at the corner portions of the temporary scaffold. The vertical length of the attachment sheet 150 is formed to be the same as the length of the vertically long strip portion 114 of the construction sheet 110. On the other hand, the width dimension of the attachment sheet 150 is set larger than the width dimension of the vertically long strip portion 114. Thereby, the attachment sheet 150 can wrap around and cover the outer periphery of the support column of the temporary scaffold.

[0020] The attachment sheet 150 includes a first overlapping strip portion 152 that is superimposed on the surface of the vertically long strip portion 114 of the sheet main body portion 112, a second overlapping strip portion 156 that is superimposed on the back surface of the right edge portion of the sheet main body portion 112, and a horizontally long strip portion 160.

[0021] The first overlapping strip portion 152 is disposed on the right side of the attachment sheet 150, and a plurality of detachable means 154 are provided along the vertical direction on the back surface side thereof. The detachable means 154 is a member that is detachably attached to the detachable means 122 provided on the vertically long strip portion 114. In this embodiment, male snap buttons are used as the detachable means 154. The detachable means 154 may be any member corresponding to the detachable means 122, for example, a hook-and-loop fastener, a magnet, a hook attached to a hanging thread, etc. Each of the detachable means 154 is provided at the same position as each detachable means 122 of the vertically long strip portion 114 in the vertical direction (up and down direction).

[0022] The second overlapping strip portion 156 is disposed on the left side in the attachment sheet 150, and a plurality of perforations 158 are provided along its vertical direction. These perforations 158 are provided at the same position in the vertical direction as the perforations 118 provided at the right edge of another construction sheet 110 disposed orthogonally, and are connected to the perforations 118 of the other construction sheet 110 using a fastener. The right edge of this second overlapping strip portion 156 is superimposed on the back side of the left edge of the first overlapping strip portion 152, and the overlapping portion is adhered.

[0023] The horizontally long strip portion 160 is a strip-shaped member extending horizontally provided at the lower end of the first overlapping strip portion 152. The horizontally long strip portion 160 is superimposed on the back side of the upper end of the first overlapping strip portion 152 of another attachment sheet 150 disposed below. Here, perforations 162, 164, and 166 are provided at the horizontally long strip portion 160 and the upper and lower ends of the first overlapping strip portion 152. The perforation 162 of the horizontally long strip portion 160 is aligned with the perforation 164 provided at the upper end of the first overlapping strip portion 152 of another attachment sheet 150 disposed below. Then, the perforation 166 of the upper attachment sheet 150, the perforation 164 of the lower attachment sheet 150, and the perforation 162 of the horizontally long strip portion 160 of the upper attachment sheet 150 are tied with a binding string. As a result, the gap between the adjacent attachment sheets 150 above and below is covered by the horizontally long strip portion 160. Note that detachable means may be provided instead of the perforations 162 and 166.

[0024] The sheet set 100 according to the present embodiment is installed as follows. As shown in FIG. 3, on the surface portion on the outer periphery of the temporary scaffold, that is, on the front portion and the side portion, a plurality of construction sheets 110a, 110b, 110c, 110d are adjacently arranged in the left-right direction and the up-down direction. These adjacent construction sheets 110a, 110b, 110c, 110d are tied together by binding strings c1 and c2 with the perforations 118 provided at their respective peripheral edges, and are also tied to the support p and the horizontal member h.

[0025] Here, when fastening the first construction sheet 110a and the second construction sheet 110b, which are adjacent to each other on the left and right, the first construction sheet 110a (right edge) is placed on top of the vertical strip portion 114b (surface side) of the second construction sheet 110b. Then, the grommet 118b on the left edge of the sheet body portion 112b of the second construction sheet 110b, the grommet 120 (not shown in Figure 3) on the vertical strip portion 114b of the second construction sheet 110b, and the grommet 118a on the right edge of the sheet body portion 112a of the first construction sheet 110a are fastened together with a single fastening string c1. As a result, the joint between the first construction sheet 110a and the second construction sheet 110b is closed by the vertical strip portion 114b. Furthermore, the binding string c1 is tied to the support post p.

[0026] When fastening the vertically adjacent first construction sheet 110a and third construction sheet 110c together, the upper edge of the third construction sheet 110c is placed on top of the horizontally elongated strip portion 116a of the first construction sheet 110a. Then, the eyelets 118a at the lower edge of the sheet body portion 112a of the first construction sheet 110a, the eyelets 124 (not shown in Figure 3) at the horizontally elongated strip portion 116a of the first construction sheet 110a, and the eyelets 118c at the upper edge of the sheet body portion 112c of the third construction sheet 110c are fastened together with a single fastening string c2. As a result, the joint between the first construction sheet 110a and the third construction sheet 110c is closed by the horizontally elongated strip portion 116a.

[0027] As shown in Figure 4, at the corner of the temporary scaffolding, the fifth construction sheet 110e, which is distributed along the outer circumference of the temporary scaffolding, and the sixth construction sheet 110f, which is positioned perpendicular to it, are arranged perpendicular to each other. At this corner, due to the structure of the temporary scaffolding, there is a support column p that extends vertically (up and down), and if the two construction sheets 110e and 110f are simply fastened together with grommets, gaps are likely to occur around the support column p. In this embodiment, at such a corner of the temporary scaffolding, an attachment sheet 150 is placed between the fifth construction sheet 110e and the sixth construction sheet 110f.

[0028] Specifically, the first overlapping strip portion 152 of the attachment sheet 150 is placed on top of the vertically elongated strip portion 114e of the fifth construction sheet 110e, and the fifth construction sheet 110e and the attachment sheet 150 are attached by attachment / detachment means 122e, 154. Then, the right edge portion of the sheet body portion 112f of the sixth construction sheet 110f is placed on top of the second overlapping strip portion 156 of the attachment sheet 150, and the positions of the grommets 158, 118f of both sheets 150 and 110f are aligned. These grommets 158, 118f and the binding string passed through the grommet 118e of the fifth construction sheet 110e are tied to the support column p.

[0029] According to the construction sheet 100 of the present invention, the joints between construction sheets 110 that are arranged adjacent to each other on the surface portion of the outer perimeter of temporary scaffolding can be reliably sealed. Specifically, one construction sheet 110 (for example, the first construction sheet 110a) and another construction sheet 110 (for example, the second construction sheet 110b) arranged adjacent to the right side of the first construction sheet 110 are arranged such that the right edge of the sheet body portion 112 of the first construction sheet 110 overlaps the vertically elongated strip portion 114 (longitudinal strip portion 114b) of the other construction sheet 110. As a result, gaps are less likely to occur between the two construction sheets 110, and the joints are reliably sealed. Furthermore, the eyelet 120 provided on the vertically elongated strip portion 114 and the eyelet 118 provided on the right edge of the sheet body portion 112 of the first construction sheet 110 are aligned, and these eyelets are fastened together with the eyelet 118 provided on the left edge of the sheet body portion 112 of the other construction sheet 110. As a result, adjacent construction sheets 110 are firmly fastened together, the vertically elongated strip portion 114 is prevented from curling up outwards, and the stability of the joint is improved. These effects occur similarly even when construction sheets 110 are arranged adjacent to each other vertically.

[0030] Furthermore, since the vertically elongated strip portion 114 and the horizontally elongated strip portion 116 are arranged in overlapping positions on the back side of the sheet body portion 112, it becomes possible to place other construction sheets 110 on top of the vertically elongated strip portion 114 and the horizontally elongated strip portion 116. As a result, the surface height of adjacent construction sheets 110 can be made uniform, and steps between sheets can be suppressed. Consequently, the surface of the construction sheets 110 can be made smooth and continuous, improving the appearance and reducing wind intrusion and snagging.

[0031] In this embodiment, the sheet set 100 has a wide attachment sheet 150 that is detachably attached to a vertically elongated strip 114 provided on the construction sheet 110, and the attachment sheet 150 is positioned between construction sheets 110 that are arranged perpendicular to each other. As a result, the vertical support columns p present at the corners of the temporary scaffolding can be covered by the attachment sheet 150. This ensures that gaps, which tend to occur at the corners of the temporary scaffolding due to the presence of support columns p in conventional construction sheets 110, are reliably sealed. Consequently, it is possible to effectively prevent construction materials, tools, etc. from flying out and falling from the joints of the construction sheets 110 that are arranged perpendicular to each other.

[0032] Although embodiments of the present invention have been described, the present invention may also be modified as follows.

[0033] In the above embodiment, the construction sheet 110 and the attachment sheet 150 may be formed symmetrically in the left-right direction. That is, in the construction sheet 110, the vertically elongated strip portion 114 may be provided along the right edge of the sheet body portion 112. Also, in the attachment sheet 150, the first overlapping strip portion 152 may be provided on the left side and the second overlapping strip portion 156 may be provided on the right side.

[0034] In the above embodiment, the construction sheet 110 and the attachment sheet 150 may be formed symmetrically in the vertical direction. That is, in the construction sheet 110, the horizontal strip portion 116 may be provided along the upper edge of the sheet body portion 112. Also, in the attachment sheet 150, the horizontal strip portion 160 may be provided above the first overlapping strip portion 152.

[0035] Alternatively, instead of the attachment and detachment means 122 and 154, a fastening means such as a hook attached to the eyelet 120 of the vertically elongated strip portion 114 may be provided on the first overlapping strip portion 152. [Explanation of symbols]
