Description

  The present invention relates to a curing structure and a curing sheet used for the curing structure.

  When constructing structures such as building or repairing structures, support rods (single pipes) are installed so as to surround the structure or work space, and a curing sheet is stretched over these support rods to enclose ( For example, Patent Document 1). Depending on the construction site, a ladder-structure beam (a structure in which two support rods are connected by a connector rod, hereinafter referred to as “flat beam”) may be used instead of the support rod. Even when a flat beam is used, binding with the curing sheet is performed with only one support rod, and the other support rod is used for reinforcement.

In addition, the curing sheet was used not only as a covering for the standing wall surface, but also as a covering for a roof surface (an inclined roof or a flat roof).
In addition, in the curing structure disclosed in Patent Document 1, it is proposed to prevent the intrusion of rain or the like by closing a gap that can be formed at the joint (adjacent) of the curing sheets when a plurality of curing sheets are stretched together. Has been. Specifically, a male hook-and-loop fastener is attached to one curing sheet so as to project toward the other (adjacent) curing sheet, and a female hook-and-loop fastener is attached to the other curing sheet. The male and female hook-and-loop fasteners were engaged to cover the joint between the curing sheets.

JP 2005-336975 A

  In the conventional curing structure, as described above, the support rod and the flat beam are supported, and the outer peripheral portion of the curing sheet is bound to these with a string. However, since the supporting rod and the flat beam do not have sufficient mechanical strength against bending, there is a disadvantage that the curing sheet cannot be pulled strongly (a strong tension cannot be applied). For this reason, the curing sheet is generally stretched in a slightly bent state between the support rods or between the flat beams.

  However, in the curing sheet stretched with bending in this way, the wind may flutter and the strength of the entire enclosure may be adversely affected. For this reason, a reinforcing structure for enhancing the installation strength of the support rod and the flat beam has been required. That is, there has been a problem that the structure of the entire enclosure becomes large, and the amount of materials used increases accordingly, which requires labor and time for loading / unloading materials, assembling / disassembling, and the like. Further, when the curing sheet is used for covering the roof surface, there is a problem that rainwater or the like accumulates in the center of the sheet surface of the curing sheet.

  On the other hand, when a plurality of curing sheets are stretched together, in the disclosed structure of Patent Document 1 that can prevent rain and the like from entering at the joints of the curing sheets, the male surface between adjacent curing sheets The combination and distance relationship between the fastener and the female hook-and-loop fastener is limited. Therefore, when using the curing sheet, it is necessary to adjust the arrangement (use direction and adjacent distance) of the curing sheet, which causes a problem that is very troublesome in terms of work. Needless to say, if the curing sheet is not properly arranged, the effect of preventing rain penetration cannot be obtained.

  The present invention has been made in view of the above circumstances, and while maintaining the ease of construction and reducing the construction cost, the curing sheet is strongly tensioned without requiring structural reinforcement ( The purpose of the present invention is to provide a curing structure that can be stretched over (in a tensioned state) and that can also prevent rain penetration at the joints of the curing sheet, and a curing sheet used in this curing structure. .

In order to achieve the above object, the present invention has taken the following measures.
That is, the curing structure according to the present invention is configured by stretching a curing sheet on both sides sandwiching the beam, and the beam is provided in parallel with each other at the four corner positions. The four support rods and the connecting rods that connect a plurality of longitudinal portions between the adjacent support rods are formed into a three-dimensional beam formed in a rectangular tube shape, and the curing sheet includes a sheet body and the sheet. A belt-like cover provided on an outer peripheral portion of the main body, and a binding portion used for binding to the long side portion of the three-dimensional beam is predetermined on the sheet main body along the side length direction of the outer peripheral portion of the sheet A plurality of the belt-like covers are provided at intervals, and the belt-like cover is placed on the inner side of the sheet with respect to the arrangement row in which the bundling portions are arranged, and covers the bundling portion over the bundling portion from the coupling end. The three-dimensional bee It is formed to have an overhang length that reaches to the adjacent curing sheet across the sheet, and the band covers of the curing sheet disposed on both sides of the three-dimensional beam are overlapped and folded in an arrangement including the three-dimensional beam It is characterized by.

In the three-dimensional beam, a long strip is installed and fixed along the longitudinal direction of the three-dimensional beam so as to be sandwiched between two support rods that bind the sheet body of the curing sheet. It is preferable that the curing sheets on both sides are folded at a position covering the strip.
On the other hand, the curing sheet according to the present invention stretches along one side in the longitudinal direction of the three-dimensional beam formed in a rectangular tube shape, and is provided on the sheet body and the outer periphery of the sheet body. A belt-like cover, and the sheet body is provided with a plurality of bundling portions used for bundling with the long side portion of the three-dimensional beam at predetermined intervals along the side length direction of the outer peripheral portion of the sheet. The cover covers the solid beam from the connecting end over the bundling portion with the connection inner side of the arrangement row where the bundling portions are arranged as a coupling end, and is further adjacent to the solid beam. It is formed in the overhang length which reaches to the curing sheet to be done.

  It is preferable that a belt-like cover is provided on the entire outer periphery of the four sides of the sheet surface formed in a quadrangle.

  The curing structure according to the present invention and the curing sheet used for the curing structure are easy to construct and reduce the construction cost, while maintaining the curing sheet with high tension without requiring structural reinforcement ( It can be stretched (in a tensioned state), and it is also possible to prevent rain penetration at the joints of the curing sheets.

Hereinafter, embodiments of the present invention will be described with reference to the drawings.
1 to 6 show a curing structure 1 according to the present invention, and FIG. 7 shows a curing sheet 2 according to the present invention used for the curing structure 1. As shown in FIG. 4, the curing structure 1 has a configuration in which a plurality of curing sheets 2 are stretched so as to surround the structure 3 and the construction space. As shown in FIG. 5, each curing sheet 2 is stretched between adjacent three-dimensional beams 4 with a three-dimensional beam 4 installed in a skeleton form corresponding to the outer periphery thereof.

As shown in FIG. 3, the three-dimensional beam 4 is composed of four support rods 5 arranged in parallel with each end being arranged at four corner positions, and a plurality of longitudinal beams between the adjacent support rods 5. It is formed in a rectangular tube shape by a connector rod 6 that connects the places. One side of the square tube is about 450 mm.
In this three-dimensional beam 4, the support rod 5 and the connector rod 6 are formed of hollow lightweight round pipes, and both are connected by welding. The connector rods 6 include those that are provided perpendicular to the longitudinal direction of the support rod 5 to form a cross rail, and those that are diagonally provided to form a diagonal member (brace). The connecting rod 6 forming the horizontal beam can be used as a ladder beam (grip bar and step bar) when the solid beam 4 is used with its longitudinal direction facing up and down.

As shown in FIG. 7, the curing sheet 2 is formed by providing a belt-like cover 11 on the outer peripheral portion of a sheet body 10 formed of a resin sheet material, a cloth, or the like. The sheet body 10 is preferably formed in a square shape such as a square or a rectangle. In this case, the belt-like cover 11 is provided on the entire outer periphery (four sides) of the sheet body 10. Is good.
A bundling portion 12 formed by attaching eyelet fittings or the like is provided on the outer peripheral portion of the sheet main body 10. The binding portion 12 is used for inserting a binding material 13 (see FIG. 2) such as a string, a wire rope, or a wire, and the binding material 13 is used to support the three-dimensional beam 4 on the support rod 5 or the like. The sheet 2 is secured. It is preferable that a plurality of bundling portions 12 are arranged at a predetermined interval so as to form a row along the side length direction of the sheet body 10. Note that a reinforcing wire 14 (see FIG. 2) made of a resin rope, a metal rope, or the like may be wound around the outer peripheral portion of the sheet main body 10 (the sheet outer side of the binding portion 12).

  The belt-like cover 11 is connected to the sheet main body 10 by bonding, sewing, or the like with the connection end 11a being a position on the inner side of the sheet from the arrangement row in which the binding portions 12 are arranged in the sheet main body 10. The belt-like cover 11 is formed to have an overhanging length that covers the solid beam 4 from the connecting end 11a over the binding portion 12 and reaches the adjacent curing sheet 2 with the solid beam 4 interposed therebetween. The belt-like cover 11 is formed of the same material with the same color as the sheet body 10. However, the color and material may be different.

  In order to configure the curing structure 1 using such a three-dimensional beam 4 and the curing sheet 2, first, a structure 3 and a skeleton surrounding the construction space are assembled by a plurality of three-dimensional beams 4 (FIGS. 3 to 5). reference). And as shown in FIG.1 and FIG.2, the supporting rod of each side part of each curing sheet 2 (sheet main body 10) and each three-dimensional beam 4 by the binding material 13 inserted in the binding part 12 of each curing sheet 2 is shown. 5 are bundled at a plurality of locations along their longitudinal direction.

In this way, the entire outer periphery of the curing sheet 2 is bound to the three-dimensional beam 4 arranged so as to be close to each side. At this time, the curing sheet 2 is strongly tensioned (the sheet surface is tightened). ). Even if it does in this way, since the three-dimensional beam 4 has strong mechanical strength with respect to a bending, it does not bend.
Thereby, since the curing sheet 2 can be stretched with a strong tension (in a tensioned state), the curing sheet 2 does not flutter due to wind. Further, it is not necessary to add a reinforcing structure to the three-dimensional beam 4 and the structure of the entire enclosure does not become large. Therefore, there is no increase in the materials used, and no effort and time are required for carrying in / out the materials, assembling and disassembling. Moreover, when the curing sheet 2 is used for covering the roof surface, the problem that rainwater or the like accumulates in the center of the sheet surface of the curing sheet 2 is also eliminated.

  Next, as shown in FIG. 1 (a), in the curing sheets 2 and 2 on both sides of the three-dimensional beam 4, the three-dimensional beam is formed while the belt-like covers 11 and 11 are aligned with the protruding ends. Overlay on 4. Then, as shown in FIGS. 1B and 1C, the overlapped belt-like covers 11, 11 are bundled around the central portion of the three-dimensional beam 4 (the sheet bodies 10, 10 of both curing sheets 2, 2 are bound together). The three-dimensional shape is folded in one direction so that the intermediate position between the two support rods 5 and 5 becomes the first folding position P and then folded back to the opposite side at the end position of the three-dimensional beam 4. Fold over the beam 4.

Arranging the first folding position P around the center of the three-dimensional beam 4 is not particularly limited. However, a range that overlaps the three-dimensional beam 4 is preferable.
By doing so, the curing sheets 2 and 2 on both sides are both bound between the sheet main body 10 and the three-dimensional beam 4 (that is, the bundling portion 12 and the bundling portion 12 to the three-dimensional beam 4). The binding material 13) is covered with the belt-like cover 11. Further, the three-dimensional beam 4 is also covered by the belt-like cover 11. Therefore, even when the curing sheets 2 are stretched, rain or the like does not enter between the adjacent curing sheets 2 and 2. Naturally, it can also prevent wind blowing. If the belt-like cover 11 is formed of a light shielding material, even light can be blocked.

Furthermore, as an effect of the band-shaped cover 11, the binding material 13 is not wetted by rain or the like, so that the binding material 13 is less prone to material deterioration and has a longer life. It is possible to obtain an effect that it is possible to wipe off the problem that the binding is difficult to unwind by including and curing (when the binding material 13 is a water-absorbing material).
As shown in FIG. 1C, when the belt-like covers 11 and 11 are folded, the belt-like covers 11 and 11 are maintained in a folded state by their own loads. For this reason, there is nothing to turn in a situation where there is no strong wind. However, as a countermeasure against the case where the curing sheet 2 is used on the wall surface or a strong wind countermeasure, it is preferable to fix the folded sheet 2 with a tape or the like in order to reliably maintain the folded state.

  For example, as shown in FIG. 6A, the tape 16 can be attached to the folded belt-like covers 11 and 11 in a direction crossing between both ends of the folding. Such affixing may be performed at a plurality of locations at appropriate intervals. Further, as shown in FIG. 6B, the tape 16 may be attached only to both ends without crossing the both ends of the folded belt-like covers 11 and 11. Alternatively, if a tape 16 having a sufficiently wide width is used, the tape 16 may be attached along the longitudinal direction of the strip cover 11 as shown in FIG. Note that it is preferable to use a strong adhesive tape having water resistance and weather resistance as the tape 16.

  As shown in FIG. 8, with respect to the three-dimensional beam 4, it is arranged between the curing sheets 2 and 2 on both sides (an arrangement between the two connector rods 6 and 6 for binding the sheet body 10 of the curing sheet 2). Thus, the long strip 20 can be installed and fixed along its longitudinal direction. In this case, the curing sheet 2 (band cover 11) on both sides is folded at a position covering the band plate 20. Therefore, the folded belt-like cover 11 can be fixed to the belt plate 20 by nail fastening, tacker fastening, screw fastening, or the like. Since the band plate 20 can be used for walking, there is an advantage that the three-dimensional beam 4 can be used as a scaffold.

By the way, this invention is not limited to the said embodiment, It can change suitably according to embodiment.
For example, in the curing sheet 2, the specific dimension of the overhang dimension of the belt-like cover 11 is not limited, but when the solid beat 4 is a square tube having a side of 450 mm, the edge of the sheet body 10 is It can be said that it is preferable to secure an overhang dimension of more than 500 mm.

  The use of the tape 16 for fixing the belt-like cover 11 is not limited, and a hook-and-loop fastener, a double-sided tape, a hook or the like can also be used. However, if these are attached to the belt-like cover 11 from the beginning, positional constraints are generated in the work of attaching the curing sheet 2 to the three-dimensional beam 4, so that when the curing sheet 2 has been attached, It is preferable to adopt a method in which a hook-and-loop fastener, a double-sided tape, a hook or the like is fixed to the cover 11 or the like.
