Description

  The present invention relates to a curing sheet installed on a scaffolding or the like of a construction site and a method for installing the same.

  In this type of curing sheet, there is a sheet that prevents a small object from falling outside the sheet from a gap between adjacent sheets (for example, see Patent Document 1). As shown in FIG. 5, when the upper and lower outer peripheral edges 420 and the left and right outer peripheral edges 430 of the mesh sheets 410 adjacent to each other are overlapped with each other, the pair of mounting holes 420a, 430a is formed so as to overlap each other. Then, the binding cords are respectively inserted so as to hang over a pair of overlapping mounting holes 430a (mounting holes 420a), and the binding cords are bound to the scaffolding column 61 on the back side of the mesh sheet 410.

  By the way, since the thing of patent document 1 inserts and binds a binding string so that it may span over a pair of overlapping attachment holes 430a (attachment hole 420a), it is very much for installation of the mesh sheet | seat 410. It takes time.

  To solve such a problem, as shown in FIG. 6, the clamp body 470a is attached to the support column 61 of the scaffold, and the mounting hole 531 of the protective sheet 510 is provided in the “L” -shaped insertion member 470b protruding from the clamp body 470a. There is one that is inserted (see, for example, Patent Document 2). According to the device described in Patent Document 2, it is not necessary to insert a binding string into each attachment hole 531 formed in the protection sheet 510 and bind it, so that it is possible to reduce the trouble of installing the protection sheet 510. it can.

  However, in the thing of patent document 2, when only the upper end part and lower end part of the protection sheet 510 are fixed by the clamp 470, a small object is outside the sheet 510 from the gap between the protection sheets 510 adjacent to the left and right. There is a risk of falling. Here, it is conceivable to fix the mesh sheet 410 described in Patent Document 1 with the clamp 470 described in Patent Document 2. In this case, since the left and right outer peripheral edges 430 of the mesh sheet 410 are overlapped, it is considered that a small object is prevented from falling outside the sheet from the gap between the mesh sheets 410.

  However, there are wind effects at actual construction sites, and high-rise building scaffolds are often exposed to strong winds. For this reason, even if the mesh sheet 410 described in Patent Document 1 is fixed by the clamp 470 described in Patent Document 2, the surfaces of the overlapping mesh sheets 410 are separated from each other by the influence of the wind at the intermediate portion in the longitudinal direction of the mesh sheet 410. It will be. As a result, in the middle part of the mesh sheet 410 in the longitudinal direction, a small object may fall outside the sheet through a gap between the surfaces.

The present invention has been made in view of the above circumstances, and for curing, capable of suppressing a small object from falling outside of a sheet from a gap between adjacent sheets while reducing labor during installation. it is an object of the present invention to provide a sheet.

  Means and effects for solving the above problems will be described below.

  1st invention is a sheet | seat for curing, Comprising: It forms in the 1st outer periphery among the rectangular sheet-shaped sheet | seat main body and the 1st outer periphery and the 2nd outer periphery which make a parallel in the said sheet | seat body and extend in a longitudinal direction. A first branch portion and a second branch portion that respectively extend to the outer peripheral end side of the first outer peripheral edge and branch into two sheets, both longitudinal ends of the second outer peripheral edge of the sheet body, and the first Formed on both ends in the longitudinal direction of the one branch portion, the second outer peripheral edge of the curing sheet adjacent to the first branch portion and the second branch portion of the sheet body in the main curing sheet is sandwiched. When sandwiching the second outer peripheral edge of the curing sheet adjacent to the through-hole that can be overlapped, and the first branch part and the second branch part of the sheet body in the main curing sheet, Front in adjacent curing sheet Characterized in that it comprises a second outer peripheral edge and the fixed anchoring structure superposed state and said second branch portion of the part and the curing sheet including the inner peripheral side of the seat body.

  According to the first aspect of the invention, the rectangular sheet-shaped sheet main body extends in the longitudinal direction in parallel with the first outer peripheral edge and the second outer peripheral edge, on the first outer peripheral edge, on the outer peripheral end side of the first outer peripheral edge, respectively. Since the first branch part and the second branch part that extend and branch into two sheets are formed, when a plurality of curing sheets are arranged adjacent to each other in the short direction, the second of the adjacent sheets The outer peripheral edge can be sandwiched between the first branch portion and the second branch portion formed on the first outer peripheral edge of the sheet. And in the both ends of the longitudinal direction of the 2nd outer periphery in the said sheet main body, and the both ends of the longitudinal direction of the said 1st branch part, the said 1st branch part and the said 2nd of the said sheet | seat body in this curing sheet Since the through-holes that can be overlapped when the second outer peripheral edge of the adjacent curing sheet is sandwiched between the branch portions are formed, they are formed at both ends in the longitudinal direction of the second outer peripheral edge of the adjacent sheet. The sheet can be fixed by superposing the through-holes and the through-holes formed at both ends in the longitudinal direction of the first branch portion of the sheet, and inserting the insertion member of the clamp. For this reason, in a state where the second outer peripheral edge of the adjacent sheet is sandwiched between the first branching portion and the second branching portion of the first outer peripheral edge of the sheet, the second outer peripheral edge of the adjacent sheet and the first outer edge of the main sheet. The branch portion can be pulled in the longitudinal direction. As a result, it is possible to install the sheet by fixing both end portions in the longitudinal direction of the sheet, so that it is possible to reduce the trouble in installing the sheet.

  Further, when the second outer peripheral edge of the adjacent curing sheet is sandwiched between the first branch portion and the second branch portion of the sheet main body in the main curing sheet, the sheet main body in the adjacent curing sheet In order to provide a fixing structure that can be fixed in a state in which the second outer peripheral edge and the portion including the inner peripheral side of the second outer peripheral edge and the second branching portion of the main curing sheet are overlapped, the second outer peripheral edge of the adjacent sheet The second branch portion of the sheet is superimposed on a portion including the second outer peripheral edge of the adjacent sheet and the inner peripheral side in a state sandwiched between the first branch portion and the second branch portion of the first outer peripheral edge of the sheet. Can be fixed. For this reason, it can suppress that a clearance gap produces between the surface of the part containing the 2nd outer periphery of the adjacent sheet | seat and its inner peripheral side, and the surface of the 2nd branch part of this sheet | seat. Therefore, even if the surface of the second outer peripheral edge of the adjacent sheet and the surface of the first branch portion of the sheet are separated by wind or the like, the gap between these surfaces is blocked by the second branch portion of the sheet. It will be. As a result, even if the sheet is affected by the wind, it is possible to suppress a small object from falling outside the sheet from the gap between adjacent sheets. The fixing structure that can be fixed in a state where the second outer peripheral edge and the inner peripheral side of the sheet main body in the adjacent curing sheet and the second branch part in the main curing sheet are overlapped with each other is a sheet. What is necessary is just to be able to fix the second outer peripheral edge and the portion including the inner peripheral side and the second branch portion at a predetermined position in the longitudinal direction of the main body.

  In addition, the surface fastener extends in the short direction of the sheet main body to a portion including the second outer peripheral edge and the inner peripheral side of the sheet main body in the adjacent curing sheet and the second branch portion of the main curing sheet. By providing this, at least a part of these hook-and-loop fasteners can be brought into close contact and fixed. As a result, the curing sheet can be easily fixed by the clamp and the hook-and-loop fastener.

Furthermore, if the first branch portion is formed integrally with the seat body and the second branch portion is attached to the seat body, the strength of the first branch portion where the through hole is formed can be secured. The structure of the curing sheet can be simplified.
Clamps by overlapping the through holes formed at both ends in the longitudinal direction of the second outer peripheral edge of the sheet body of the adjacent sheet and the through holes formed at both ends in the longitudinal direction of the first branch portion of this sheet When the insertion member or the like is inserted, interference between the second branch portion of the sheet and the insertion member or the like of the clamp becomes a problem.
In this regard, in the first invention, the second branch portion of the sheet main body has longitudinal ends of the second outer peripheral edge of the sheet main body in the longitudinal direction of the sheet main body and the longitudinal direction of the first branch portion. Since it is provided only inside the through-holes formed at both end portions, the second branch portion of the sheet can avoid a clamp insertion member and the like. As a result, even if it is a curing sheet having a first branch portion and a second branch portion that extend to the outer peripheral end side of the first outer peripheral edge of the sheet main body and branch into two sheets, there is no problem due to clamping or the like. Can be installed.

  According to a second invention, in the first invention, the second branch portion is formed to extend longer to the outer peripheral end side of the first outer peripheral edge of the seat body than the first branch portion, and the fixing structure is When the second outer peripheral edge of the adjacent curing sheet is sandwiched between the first branch portion and the second branch portion of the sheet main body in the main curing sheet, the sheet main body in the adjacent curing sheet Since it is possible to fix the inner portion of the through hole formed in the second outer peripheral edge in the short direction and the second branch portion of the curing sheet, the second outer peripheral edge of the adjacent sheet and its inner periphery The width where the portion including the side overlaps with the second branch portion of the present sheet can be made wider than the width where the second outer peripheral edge of the adjacent sheet overlaps with the first branch portion of the present sheet. As a result, even if the width where the second outer peripheral edge of the adjacent sheet overlaps with the first branching portion of the main sheet cannot be widened due to restrictions due to the position where the sheet is installed, the clamp configuration, etc. It can suppress that a gap | interval arises between the sheets to perform.

Here, a 1st structure is parallel to the line segment which connects the said through-holes formed in the longitudinal direction both ends of the 2nd outer periphery in the said sheet | seat main body, and the longitudinal direction both ends of the said 1st branch part. And is arranged on the outer peripheral end side of the sheet main body with respect to the through-hole, and is formed shorter than the parallel line segment and has a string with both ends fixed to the sheet main body. When the sheet is stretched and the sheet is pulled by applying a clamp or the like to the through hole, the string is stretched more than before the sheet is installed. For this reason, tension is generated in the string disposed on the outer peripheral end side of the sheet main body with respect to the through hole, and the outer periphery of the sheet can be held linearly by the tension of the string. Therefore, even when a force that pushes the surface of the sheet is applied, the outer shape of the sheet can be prevented from being deformed to the inner peripheral side. As a result, it is possible to further suppress the occurrence of a gap between adjacent sheets.

The second configuration is that in the first configuration , the string is further fixed when the sheet is installed and the string is extended because the middle portion is fixed to the seat body. The intermediate portion can be pulled toward both end portions. For this reason, compared with the case where only both ends of the string are fixed to the sheet body, the tension of the string can be efficiently transmitted to the middle part of the sheet body, so that the outer shape of the sheet is deformed to the inner peripheral side. This can be further suppressed.

In the third configuration , the second branch portion of the sheet main body has a through hole at a position overlapping with the through hole formed at both ends of the first branch portion in the longitudinal direction of the sheet main body. Thus, the sheet can be fixed by inserting a clamp insertion member or the like through the through hole formed in the first branch portion and the through hole formed in the second branch portion of the seat body. Even with such a configuration, the sheet can be installed without problems by a clamp or the like. Furthermore, since the second branch portion of the sheet body can be pulled in the longitudinal direction, it is possible to suppress the occurrence of a gap between the second outer peripheral edge of the adjacent sheet and the second branch portion of the sheet. . In the sheet for curing, which is adjacent to the through hole formed in the longitudinal end of the first branch portion in the sheet body and the through hole formed in the second branch portion of the sheet body. A fixing structure that can be fixed in a state where the second outer peripheral edge of the sheet main body and the portion including the inner peripheral side thereof and the second branching portion of the main curing sheet are overlapped can also be configured.

  In a state where the second outer peripheral edge of the adjacent sheet and the first outer peripheral edge of the present sheet overlap, the portion including the second outer peripheral edge of the adjacent sheet and the inner peripheral side thereof and the second branch portion of the present sheet are fixed. In a portion where the fixing structure is not provided, when a force that pushes the surface of the sheet is applied, the sheet is displaced so that the overlapping width of the outer peripheral edges is narrowed. When such a shift of the sheet becomes large, there is a possibility that the outer peripheral edges of the sheets are not overlapped and a gap is generated. Here, such a shift of the sheet becomes larger as the distance from the fixing structure that fixes the second outer peripheral edge of the sheet main body and the portion including the inner peripheral side and the second branch portion increases. On the other hand, when a continuous fixing structure is provided over the entire length in the longitudinal direction, the cost of the sheet increases.

In this regard, the third invention is the curing sheet according to the first or second invention, wherein the fixing structure is adjacent to the first branch portion and the second branch portion of the sheet body in the main curing sheet. When the second outer peripheral edge of the sheet body is sandwiched, the second outer peripheral edge of the sheet main body of the adjacent curing sheet and the inner part thereof at the positions at predetermined intervals between the longitudinal ends of the sheet main body and the intermediate part. Since the portion including the peripheral side and the second branch portion of the main curing sheet can be fixed, the displacement of the sheet is suppressed at the positions of both end portions and intermediate portions in the longitudinal direction of the sheet body. be able to. For this reason, it can suppress that a part with a long distance from a fixed structure is formed, without providing a continuous fixed structure over the full length of a longitudinal direction. As a result, it is possible to suppress a gap between the sheets while suppressing an increase in the cost of the sheet. Furthermore, since it is possible to fix the second outer peripheral edge of the adjacent sheet and the portion including the inner peripheral side thereof and the second branch portion of the present sheet at both ends in the longitudinal direction of the sheet main body, It can suppress that a 2nd branch part turns up from both ends.

According to a fourth aspect of the present invention, in any one of the first to third aspects, the through-hole formed in the second outer peripheral edge and the first branch portion in the sheet main body is the sheet main body in the main curing sheet. When the second outer peripheral edge of the adjacent curing sheet is sandwiched between the first branch portion and the second branch portion, two are formed side by side in the short direction of the sheet body so as to overlap each other. Therefore, by inserting two insertion members of the clamp through the two through holes formed side by side, the second outer peripheral edge of the sheet adjacent to the two through holes and the first branch of the main sheet It is possible to secure a width in which the portions overlap. As a result, the second outer peripheral edge of the adjacent sheet can be prevented from coming off between the first branch portion and the second branch portion of the sheet, and a force that pushes the surface of the sheet acts. Even if the sheets are displaced, it is possible to suppress the overlap between the outer peripheral edges of the sheets. Furthermore, by inserting two insertion members of the clamp through the two through holes formed side by side, the insertion member of the clamp is centered compared to the case of inserting the insertion member of the clamp through the one through hole. The rotation of the sheet can be suppressed. For this reason, it can suppress that the outer periphery of a sheet | seat moves, and can further suppress that a clearance gap produces between adjacent sheets.

The first method is a method for installing a first curing sheet and a second curing sheet consisting of either nutrient raw sheet described above to the scaffold by a clamp, before Symbol first curing sheet A step of sandwiching a second outer peripheral edge of the second curing sheet between the first branching portion and the second branching portion of the sheet main body, and a second of the second curing sheet in the sheet main body. A step of superimposing the through-holes formed so as to be superposed on both ends in the longitudinal direction of the outer peripheral edge and both ends in the longitudinal direction of the first branch portion in the first curing sheet; A step of inserting the insertion member of the clamp into the through holes overlapped with each other and fixing the clamp to the support column of the scaffold; a second outer peripheral edge of the seat body in the second curing sheet and an inner periphery thereof ~ side Characterized in that in a state of superposing the portions and the second branch portion of the first curing sheet containing and a step of fixing by the fixing structure.

According to the first method , the second outer peripheral edge of the second curing sheet is sandwiched between the first branch portion and the second branch portion of the sheet body in the first curing sheet. And it superimposes on the both ends of the longitudinal direction of the 2nd outer periphery in the said sheet | seat main body of the said 2nd curing sheet, and the both ends of the longitudinal direction of the said 1st branch part in the said 1st curing sheet. The through holes formed as possible are overlapped with each other, and the insertion member of the clamp is inserted into the through holes overlapped with each other so that the clamp is fixed to the support column of the scaffold. For this reason, in the state where the second outer peripheral edge of the second curing sheet is sandwiched between the first branching portion and the second branching portion of the first outer peripheral edge of the first curing sheet, The second outer peripheral edge and the first branch portion of the first curing sheet can be pulled in the longitudinal direction. As a result, since the sheet can be installed by fixing both ends in the longitudinal direction of the sheet with clamps, it is possible to reduce time and labor when installing the sheet.

  Further, in the second curing sheet, the second outer peripheral edge of the second curing sheet is sandwiched between the first branching portion and the second branching portion of the first outer peripheral edge of the first curing sheet. A portion including the second outer peripheral edge and the inner peripheral side of the sheet main body and the second branch portion of the first curing sheet are fixed by the fixing structure. For this reason, it suppresses that a clearance gap produces between the surface of the part containing the 2nd outer periphery of the 2nd curing sheet and its inner peripheral side, and the surface of the 2nd branch part in the 1st curing sheet. be able to. Therefore, even if the surface of the second outer peripheral edge of the second curing sheet and the surface of the first branch portion of the first curing sheet are separated by wind or the like, the gap between these surfaces is the first curing. It will be blocked by the second branch portion of the sheet for use. As a result, even if the sheet is affected by the wind, it is possible to suppress a small object from falling outside the sheet from the gap between adjacent sheets.

  Hereinafter, an embodiment will be described with reference to FIGS.

  As shown in FIG. 1, the curing sheet 10 includes a rectangular sheet-like sheet body 20. The sheet body 20 is formed in a mesh shape, and has air permeability and translucency. The sheet body 20 includes a first outer peripheral edge 21 and a second outer peripheral edge 22 that extend in the longitudinal direction in parallel. That is, the first outer peripheral edge 21 and the second outer peripheral edge 22 are outer peripheral edges on the long side of the sheet body 20.

  The first outer peripheral edge 21 is branched into two sheets, and a front branching portion 21a (first branching portion) disposed on the front side and a back branching portion 21b (first branching portion) disposed on the back side of the sheet body 20 are arranged. 2 branch portions). The front branch portion 21 a is formed in a belt shape having a constant width over the entire length of the sheet body 20 in the longitudinal direction. The back branch part 21b is formed in a belt shape having a constant width with a length excluding the end part 21c and the end part 21d from the front branch part 21a. The front branch portion 21a and the back branch portion 21b have the same end position on the center side of the sheet body 20. That is, in the seat body 20, a portion on the outer peripheral side of the sewing portion 21e where the back branching portion 21b is sewn is a front branching portion 21a. The front branch portion 21 a and the back branch portion 21 b are formed on the first outer peripheral edge 21 of the seat body 20 and extend to the outer peripheral end side of the first outer peripheral edge 21. The front branching portion 21 a of the first outer peripheral edge 21 and the second outer peripheral edge 22 are formed with an equal width in the lateral direction of the sheet body 20. Therefore, when the plurality of curing sheets 10 are arranged in the lateral direction so that the first outer peripheral edge 21 and the second outer peripheral edge 22 overlap with each other, the front branching portion 21a and the back branching portion 21b have a second outer side. The peripheral edge 22 can be sandwiched, and the front branching portion 21a of the first outer peripheral edge and the second outer peripheral edge 22 can be overlapped. And since the back branch part 21b is formed in the width | variety wider than the front branch part 21a, the back branch part 21b protrudes to the outer peripheral end side of the sheet | seat main body 20 rather than the front branch part 21a. In other words, the back branch portion 21b extends longer to the outer peripheral end side of the first outer peripheral edge 21 in the seat body 20 than the front branch portion 21a. Therefore, when the plurality of sheets 10 are arranged so that the first outer peripheral edge 21 and the second outer peripheral edge 22 overlap each other, the second outer peripheral edge 22 and the inner peripheral portion 23 on the inner peripheral side thereof and the first outer peripheral edge 21. The width where the back branching portion 21b overlaps can be made wider than the width where the second outer peripheral edge 22 and the front branching portion 21a of the first outer peripheral edge 21 overlap.

  A pair of through holes are formed by a pair of eyelets 31 in the end portion 21 c of the front branching portion 21 a in the first outer peripheral edge 21 and the end portion 22 c of the second outer peripheral edge 22. These eyelets 31 are attached at positions where they can be overlapped when the curing sheets 10 are arranged side by side in the lateral direction. Therefore, when a plurality of curing sheets 10 are installed side by side in the short direction, the pair of through holes of the front branching portion 21a in the first sheet (main sheet) and the second sheet (adjacent sheet) ) And the pair of through-holes on the second outer peripheral edge can be overlapped and the insertion member of the clamp can be inserted. A pair of eyelets 31 are attached to the end portion 21 d of the front branching portion 21 a in the first outer peripheral edge 21 and the end portion 22 d of the second outer peripheral edge 22 at a predetermined interval in the longitudinal direction of the sheet body 20. . When the plurality of curing sheets 10 are arranged side by side in the short direction, the through holes formed by these eyelets 31 can be overlapped, and the insertion member of the clamp can be inserted. The curing sheet 10 has a length in the longitudinal direction set to 5400 mm, and a pair of eyelets 31 attached to the second outer peripheral edge 22 from the center of the pair of eyelets 31 attached to the front branching portion 21a in the short direction. The length to the center of each other is set to 1800 mm. And since the eyelet 31 is attached to the edge part 21d of the front branch part 21a and the edge part 22d of the 2nd outer periphery 22 in the longitudinal direction of the sheet | seat main body 20 with the predetermined space | interval, it is in positional relationship with a clamp. The through-hole to be used can be selected accordingly. For this reason, even if it is a case where the position which can fix a clamp in the support | pillar of a scaffold has a restriction | limiting, the sheet | seat 10 for curing can be pulled appropriately in a longitudinal direction.

  The back branch portion 21b of the sheet main body 20 includes end portions 22c and 22d of the second outer peripheral edge 22 of the sheet main body 20 and end portions 21c of the front branch portion 21a of the first outer peripheral edge 21 in the longitudinal direction of the sheet main body 20. It is provided only inside the eyelet 31 attached to 21d. For this reason, when a plurality of curing sheets 10 are arranged side by side in the lateral direction, it is possible to avoid the through holes formed by these eyelets 31 being covered by the back branching portion 21b.

  A pair of hook-and-loop fasteners 41 and 42 (fixed) are provided at both ends in the longitudinal direction of the back branching portion 21b in the first outer peripheral edge 21 and the inner peripheral portion 23 on the inner peripheral side of the seat body 20 relative to the second outer peripheral edge 22. Structure) is provided. The hook-and-loop fasteners 41 and 42 fix the contacted portions by bringing the surfaces into close contact with each other. The surface fastener 41 is provided on the front surface of the back branch portion 21 b, and the surface fastener 42 is provided on the back surface of the inner peripheral portion 23. The surface fastener 41 and the surface fastener 42 are formed in a rectangular shape having the same dimensions, and are provided at the same position in the longitudinal direction of the sheet body 20. With respect to the short direction of the seat body 20, the distance from the eyelet 31 attached to the front branching portion 21a to the hook-and-loop fastener 41 is substantially equal to the distance from the eyelet 31 attached to the second outer peripheral edge 22 to the hook-and-loop fastener 42. Is set. For this reason, the plurality of curing sheets 10 are arranged side by side in the short direction, and the pair of eyelets 31 attached to the front branching portion 21a and the pair of eyelets 31 attached to the second outer peripheral edge 22 are overlapped. Sometimes, the surface fastener 41 and the surface fastener 42 can be overlapped. In addition, the surface fasteners 41 and 42 are similarly provided in the center part of the sheet body 20 in the longitudinal direction.

  In the sheet main body 20, a string 51 b is disposed on the first outer peripheral edge 21 and the second outer peripheral edge 22 that extend in the longitudinal direction in parallel, and the outer peripheral edge 26 on the short side that extends in the lateral direction in parallel. Is provided with a string 51a. These strings 51a and 51b are arranged inside the reinforcing member 54 provided along the outer peripheral edge of the sheet main body 20 and the outer peripheral edge of the sheet main body 20 in an overlapping manner. And the string 51a, 51b is each hold | maintained in parallel with respect to the outer periphery of the sheet | seat main body 20 by sewing this folded-back part. The strings 51 a and 51 b are disposed on the outer peripheral end side of the eyelet 31 in the longitudinal direction and the short direction of the sheet main body 20. In other words, the strings 51a and 51b are through holes formed in both longitudinal end portions of the second outer peripheral edge 22 of the seat body 20 and both longitudinal end portions of the front branching portion 21a in the first outer peripheral edge 21. It is arranged on the outer peripheral end side of the sheet main body 20 with respect to the line segment connecting the (eyelet 31) in parallel to the through hole. Both ends of the string 51 a are sewn to the sheet main body 20 with a thread 52. Further, the string 51a is sewn at intervals of 1/3 width in the short direction of the sheet main body 20. For this reason, when the string 51a is pulled, the sewn portion is pulled by the tension of the string 51a. Moreover, the string 51a is formed shorter than the line segment connecting the eyelets 31 attached to the most ends at both ends of the sheet body 20 in the short direction. For this reason, when the sheet | seat main body 20 is pulled in the transversal direction so that there may be no slack, it will be in the state by which the string 51a was extended. In addition, the string 51b arrange | positioned by the front branch part 21a and the 2nd outer periphery 22 of the 1st outer periphery 21 in the sheet | seat main body 20 is also arrange | positioned in the aspect similar to the string 51a. In other words, the string 51b is attached to the end side of the longitudinal direction of the sheet main body 20 while the both ends of the string 51b and the portion of the 1/3 width interval are sewn together. It is formed shorter than the line segment connecting the formed eyelets 31.

  Next, with reference to FIG. 2, a method of arranging a plurality of curing sheets 10 in a short direction and installing them on a scaffolding at a construction site will be described. In FIG. 2, the right sheet is referred to as a first curing sheet 10, and the left sheet is referred to as a second curing sheet 10.

  In the portion where the first curing sheet 10 and the second curing sheet 10 overlap, the front branching portion 21a and the back branching portion 21b of the sheet body 20 in the first curing sheet 10 are used for the second curing. The second outer peripheral edge 22 of the sheet 10 is sandwiched. Here, the front branching portion 21a of the first outer peripheral edge 21 in the first curing sheet 10 and the second outer peripheral edge 22 of the second curing sheet 10 are formed with an equal width in the lateral direction of the sheet body 20. Has been. Therefore, when the second outer peripheral edge 22 of the second curing sheet 10 is fully inserted between the front branching portion 21a and the back branching portion 21b of the first curing sheet 10, the first curing is performed. The front branching portion 21a of the first outer peripheral edge 21 of the sheet for use 10 and the second outer peripheral edge 22 of the second curing sheet 10 are overlapped.

  At this time, in the first curing sheet 10, a pair of through holes (a pair of eyelets 31) formed at both ends in the longitudinal direction of the second outer peripheral edge 22 in the sheet body 20 of the second curing sheet 10. A pair of through holes (a pair of eyelets 31) formed at both ends in the longitudinal direction of the front branching portion 21a are superposed. Since the back branch portion 21b is not provided at the position of the paired through holes, these through holes are not covered by the back branch portion 21b. Therefore, the insertion member 70b of the clamp 70 temporarily fixed to the support column 61 of the scaffold is inserted through these superimposed through holes. Here, the scaffold includes a horizontal member 62 in addition to the support 61. For this reason, the clamp 70 is temporarily fastened at a position avoiding the horizontal member 62 and the like. In the eyelet 31 attached to the end 21d of the front branching portion 21a at a predetermined interval, any eyelet 31 is selected and used according to the position of the clamp 70 fixed to the support 61. Then, by clamping the clamp 70 and fixing it to the support 61, the front branching portion 21a of the first curing sheet 10 and the second outer peripheral edge 22 of the second curing sheet 10 are arranged in the longitudinal direction of the sheet body 20. Pulled. Since these through holes are formed as a pair side by side in the lateral direction of the sheet main body 20, by inserting the two insertion members 70b of the clamp 70 through the pair of through holes, the distance between the pair of through holes It is possible to secure a width in which the second outer peripheral edge 22 of the second curing sheet 10 and the front branching portion 21a of the first curing sheet 10 overlap each other. Furthermore, by inserting the two insertion members 70b of the clamp 70 into a pair of through holes formed side by side in the short direction, the clamp insertion member can be inserted into one through hole as compared with the case of inserting the insertion member of the clamp. The rotation of the curing sheet 10 around the insertion member can be suppressed. Note that the curing sheet 10 is similarly fixed by the clamp 70 in other portions where the plurality of curing sheets 10 overlap in the short direction. When the curing sheets 10 are arranged side by side in the longitudinal direction, for example, through holes formed in the end portion 21d of the front branch portion 21a in the upper sheet 10 and the end portion of the front branch portion 21a in the lower sheet The insertion member 70b of the clamp 70 is inserted through the through hole formed in 21c. Accordingly, in the portion where the plurality of curing sheets 10 overlap in the short direction and the longitudinal direction, the insertion members 70b of the clamp 70 are inserted through the overlapping through holes of the four curing sheets 10.

  Thus, when the insertion member 70b of the clamp 70 is inserted into the through holes of the first and second curing sheets 10 and the clamp 70 is fixed, the curing sheet 10 is pulled by the clamp 70. Here, the cords 51 a and 51 b disposed along the outer peripheral edge of the sheet main body 20 of the curing sheet 10 are disposed closer to the outer peripheral edge of the sheet main body 20 than the eyelets 31 attached to the four corners of the sheet main body 20. In addition, the distance is set shorter than the distance between the eyelets 31 at the four corners. For this reason, when the curing sheet 10 is fixed by the clamp 70, the strings 51a and 51b are stretched. Accordingly, tension is generated in the strings 51a and 51b, and the outer periphery of the sheet body 20 can be held linearly. And even if the force which pushes the surface of the sheet | seat 10 for curing acts, it moves to the direction where the sheet | seat 10 for curing was pushed, and the external shape of the sheet | seat 10 for a deformation | transformation deform | transforms into an inner peripheral side. Can be suppressed. Moreover, the string 51a, 51b is sewn with a thread at a position having a length of 1/3 from both ends and both ends. For this reason, when tension | tensile_strength generate | occur | produces in the strings 51a and 51b, it will be in the state by which this sewn part was each pulled to the both-ends side of the strings 51a and 51b. Therefore, the tension | tensile_strength of string 51a, 51b can be efficiently transmitted to the position of 1/3 length from the both ends of string 51a, 51b, and the slack of the outer periphery of the sheet | seat 10 for curing can be suppressed.

  Next, the surface fastener 41 provided on the surface on the back side of the sheet body 20 in the second curing sheet 10 is replaced with the surface fastener 41 provided on the surface on the front side of the back branch portion 21b in the first curing sheet 10. Fix in close contact. Since the hook-and-loop fasteners 41 and 42 are provided at both ends and the center in the longitudinal direction of the back-branching portion 21b, the back-branching portion in the first curing sheet 10 is provided without excessively providing the hook-and-loop fasteners 41 and 42. The minimum necessary part of 21b can be fixed to the back side surface of the sheet body 20 in the second curing sheet 10. That is, when a force that pushes the surface of the curing sheet 10 is applied, the back branch portion 21b of the first curing sheet 10, the second outer peripheral edge 22 of the second curing sheet 10, and the inner periphery thereof. The curing sheet 10 is shifted so that the width of the overlapping portion 23 is narrowed. On the other hand, when both ends and the center in the longitudinal direction of the back branch portion 21b are fixed by the hook-and-loop fasteners 41 and 42, as compared with the case where only both ends are fixed by the hook-and-loop fasteners 41 and 42, for curing. The deviation width of the sheet 10 can be reduced to substantially half.

  A portion where the first and second curing sheets 10 overlap will be described with reference to FIG. FIG. 3 is a cross-sectional view taken along line 3-3 in FIG. 1, and shows a mode in which these sheets 10 are fixed by the clamp 70 and the surface fasteners 41 and 42.

  A pair of through holes (a pair of eyelets 31) formed in the second outer peripheral edge 22 of the sheet body 20 of the second curing sheet 10 and a pair formed at the front branching portion 21a of the first curing sheet 10. In a state where the through holes (the pair of eyelets 31) are overlapped, the pair of through holes are inserted by the pair of insertion members 70 b of the clamp 70. At this time, the back branching portion 21b of the first curing sheet 10 passes between the second outer peripheral edge 22 of the second curing sheet 10 and the support column 61 of the scaffold, and the second curing is performed from the lower side of the clamp 70. The sheet 10 is disposed on the surface fastener 42 side. Note that the other (lower side) end of the back branch portion 21b in the longitudinal direction of the sheet body 20 is disposed from the upper side of the clamp 70 to the surface fastener 42 side of the second curing sheet 10. That is, the back branch portion 21 b is passed between the two clamps 70 arranged in the longitudinal direction of the sheet main body 20.

  At this time, since the surface fastener 41 and the surface fastener 42 face each other, the surface fasteners 41 and 42 are fixed in contact with each other. When the hook and loop fasteners 41 and 42 are thus fixed, the second outer peripheral edge 22 of the second curing sheet 10 is sandwiched between the front branching portion 21a and the back branching portion 21b of the first curing sheet 10. They are in contact with each other. Therefore, it is suppressed that a clearance gap arises between these three sheet-like parts overlapped. Here, even if a gap occurs between the surface of the front branching portion 21a in the first curing sheet 10 and the surface of the second outer peripheral edge 22 in the second curing sheet 10 due to the influence of wind or the like, This gap is closed by the back branching portion 21b of the first curing sheet 10.

  Moreover, the hook and loop fastener 41 provided in the back branch part 21b in the 1st sheet | seat 10 for curing is provided in the inner peripheral part 23 in the inner peripheral side rather than the 2nd outer periphery 22 of the sheet | seat 10 for 2nd curing. It is fixed to the hook and loop fastener 42. For this reason, the width at which the back branch portion 21 b overlaps with the second outer peripheral edge 22 and the inner peripheral portion 23 is wider than the width at which the front branch portion 21 a overlaps with the second outer peripheral edge 22. Accordingly, the width at which the front branching portion 21 a overlaps with the second outer peripheral edge 22 is limited by the distance between the pair of insertion members 70 b of the clamp 70, but the width at which the back branching portion 21 b overlaps with the second outer peripheral edge 22 and the inner peripheral portion 23. Can be made wider.

  According to the embodiment described above in detail, the following excellent effects can be obtained.

  Of the first outer peripheral edge 21 and the second outer peripheral edge 22 that extend in the longitudinal direction in parallel in the rectangular sheet-shaped sheet main body 20, the first outer peripheral edge 21 extends to the outer peripheral end side of the first outer peripheral edge 21. Since the front branching portion 21a and the back branching portion 21b that branch into a sheet are formed, when the plurality of curing sheets 10 are arranged adjacent to each other in the short direction, the second outside of the adjacent sheets 10 The peripheral edge 22 can be sandwiched between the front branch part 21 a and the back branch part 21 b formed on the first outer peripheral edge 21 of the sheet 10. And a pair of through-holes (eyelet 31) which can be overlap | superposed on the edge parts 22c and 22d of the longitudinal direction of the 2nd outer periphery 22 in the sheet | seat main body 20 and the edge parts 21c and 21d of the longitudinal direction of the table | surface branch part 21a. Since it is formed, a pair of through-holes (eyelet 31) formed in the longitudinal ends 21c and 21d of the second outer peripheral edge 22 of the adjacent sheet 10 and the longitudinal direction of the front branching portion 21a in the present sheet 10 The sheet 10 can be fixed by inserting a pair of through-holes (eyelet) formed in the end portions 21c and 21d and inserting the insertion member 70b of the clamp 70. Therefore, the second outer peripheral edge 22 of the adjacent sheet 10 in a state where the second outer peripheral edge 22 of the adjacent sheet 10 is sandwiched between the front branch portion 21a and the back branch portion 21b of the first outer peripheral edge 21 of the sheet 10. And the front branching portion 21a of the sheet 10 can be pulled in the longitudinal direction. As a result, the sheet 10 can be installed by fixing both end portions in the longitudinal direction of the sheet 10, so that it is possible to reduce time and labor when installing the sheet 10.

  Moreover, since the surface fastener 41 and 42 which can be fixed in the state which overlap | superposed the part including the 2nd outer periphery 22 of the sheet | seat main body 20 and the inner peripheral part 23 of the inner peripheral side and the back branch part 21b are adjoining, it adjoins. In a state where the second outer peripheral edge 22 of the sheet 10 is sandwiched between the front branching portion 21 a and the back branching portion 21 b of the first outer peripheral edge 21 of the sheet 10, the second outer peripheral edge 22 and the inner peripheral portion 23 of the adjacent sheet 10. The back branching portion 21b of the sheet 10 can be overlapped and fixed to the portion including. For this reason, it can suppress that a clearance gap produces between the surface of the part containing the 2nd outer periphery 22 and the inner peripheral part 23 of the adjacent sheet | seat 10, and the surface of the back branch part 21b of this sheet | seat 10. Therefore, even if the surface of the second outer peripheral edge 22 of the adjacent sheet 10 and the surface of the front branching portion 21a of the sheet 10 are separated by wind or the like, the gap between these surfaces is a back branching portion 21b of the sheet 10. It will be blocked by. As a result, even if the sheet 10 is affected by the wind, it is possible to prevent a small object from falling outside the sheet 10 from the gap between the adjacent sheets 10.

  The back branch portion 21b is formed so as to extend longer to the outer peripheral end side of the first outer peripheral edge 21 in the seat body 20 than the front branch portion 21a, and the surface fasteners 41 and 42 extend in the longitudinal direction of the seat body 20 in the second outer direction. Since the inner peripheral part 23 and the back branch part 21b inside the through hole formed in the peripheral edge 22 can be fixed, the part including the second outer peripheral edge 22 and the inner peripheral part 23 of the adjacent sheet 10 and the main sheet The width at which the ten back branch portions 21 b overlap can be made wider than the width at which the second outer peripheral edge 22 of the adjacent sheet 10 and the front branch portion 21 a of the main sheet 10 overlap. As a result, there is a case where the width where the second outer peripheral edge 22 of the adjacent sheet 10 overlaps with the front branching portion 21a of the present sheet 10 cannot be widened due to restrictions due to the position where the sheet 10 is installed and the configuration of the clamp 70. However, it is possible to suppress the occurrence of a gap between adjacent sheets 10.

  The curing sheet 10 has through holes (eyelet 31) formed in the longitudinal ends 22c, 22d of the second outer peripheral edge 22 of the sheet body 20 and the longitudinal ends 21c, 21d of the front branching portion 21a. The cords 51a and 51b are provided in parallel to the line segment connecting the two and arranged on the outer peripheral end side of the sheet body 20 with respect to the through holes. These strings 51 a and 51 b are formed shorter than the parallel line segments, and both ends are fixed to the sheet body 20. For this reason, if the sheet | seat 10 is expanded and the sheet | seat 10 is pulled by applying the clamp 70 to a through-hole, it will be in the state which the string 51a, 51b was extended rather than before installing the sheet | seat 10. FIG. Therefore, tension is generated in the cords 51a and 51b disposed on the outer peripheral end side of the sheet main body 20 with respect to the through hole, and the outer periphery of the sheet 10 is held linearly by the tension of the cords 51a and 51b. Can do. Therefore, even when a force that pushes the surface of the sheet 10 is applied, the outer shape of the sheet 10 can be prevented from being deformed to the inner peripheral side. As a result, it is possible to further suppress the occurrence of a gap between adjacent sheets 10.

  Since both ends and the intermediate portion of the strings 51a and 51b are fixed to the sheet body 20, when the sheet 10 is installed and the strings 51a and 51b are extended, the fixed intermediate portions are It can be pulled to both ends. For this reason, compared with the case where only the both ends of the strings 51a and 51b are fixed to the sheet main body 20, the tension of the strings 51a and 51b can be efficiently transmitted to the intermediate part of the sheet main body 20. It is possible to further suppress the deformation of the outer shape 10 toward the inner peripheral side.

  Through holes formed in the longitudinal end portions 22c and 22d of the second outer peripheral edge 22 in the sheet body 20 of the adjacent sheet 10, and formed in the longitudinal end portions 21c and 21d of the front branching portion 21a in the sheet 10. When the inserted through-hole 70b of the clamp 70 is inserted through the overlapped through-holes, interference between the back branching portion 21b of the sheet 10 and the insertion member 70b of the clamp 70 becomes a problem.

  In this regard, the back branch portion 21b of the sheet body 20 is more than the through holes formed in the longitudinal end portion 22c and the end portion 22d of the second outer peripheral edge 22 of the sheet body 20 in the longitudinal direction of the sheet body 20. The back branch portion 21b of the sheet 10 is clamped because it is provided only on the inner side and only on the inner side of the through holes formed in the end portions 21c and 21d in the longitudinal direction of the front branch portion 21a. The 70 insertion members 70b can be avoided. As a result, even if it is the curing sheet 10 including the front branching portion 21a and the back branching portion 21b that respectively extend to the outer peripheral end side of the first outer peripheral edge 21 of the sheet main body 20 and branch into two sheets, the clamp 70 Can be installed without problems.

  In a state where the second outer peripheral edge 22 of the adjacent sheet 10 and the first outer peripheral edge 21 of the present sheet 10 overlap, a portion including the second outer peripheral edge 22 of the adjacent sheet 10 and the inner peripheral portion 23 on the inner peripheral side thereof; In a portion where the surface fasteners 41 and 42 for fixing the back branch portion 21b of the sheet 10 are not provided, the first outer peripheral edge 21 and the second outer peripheral edge 22 are applied when a force that pushes the surface of the sheet 10 is applied. Therefore, the sheet 10 is displaced so that the overlapping width becomes smaller. When such a shift of the sheet 10 becomes large, there is a possibility that the first outer peripheral edge 21 and the second outer peripheral edge 22 of the sheet 10 are not overlapped and a gap is generated. Here, such a shift of the sheet 10 is such that a portion having a longer distance from the surface fasteners 41 and 42 that fixes the portion including the second outer peripheral edge 22 and the inner peripheral portion 23 of the sheet main body 20 and the back branch portion 21b. growing. On the other hand, when the continuous surface fasteners 41 and 42 are provided over the entire length in the longitudinal direction, the cost of the sheet 10 increases.

  In this respect, the hook and loop fasteners 41 and 42 fix the back branching portion 21b and the portion including the second outer peripheral edge 22 and the inner peripheral portion 23 of the sheet main body 20 at both ends and the central portion of the sheet main body 20 in the longitudinal direction. Since it is possible, the shift | offset | difference of the said sheet | seat 10 can be suppressed in the both ends and the center part in the longitudinal direction of the sheet | seat main body 20. For this reason, it can suppress that a part with a long distance from the surface fasteners 41 and 42 is formed, without providing the continuous surface fasteners 41 and 42 over the full length of a longitudinal direction. As a result, it is possible to suppress a gap between the sheets 10 while suppressing an increase in the cost of the sheet 10. Furthermore, since the portion including the second outer peripheral edge 22 and the inner peripheral portion 23 of the adjacent sheet 10 and the back branch portion 21b of the main sheet 10 can be fixed at both ends in the longitudinal direction of the main sheet body 20, the main sheet 20 can be fixed. It can suppress that the back branch part 21b turns up from the both ends of 10 longitudinal directions.

  Since the through holes formed in the second outer peripheral edge 22 and the front branching portion 21a in the sheet body 20 are formed as a pair side by side in the lateral direction of the sheet body 20, the pair of through holes formed side by side are formed. By inserting the pair of insertion members 70b of the clamp 70 into the holes, a width is secured in which the second outer peripheral edge 22 of the adjacent sheet 10 and the front branching portion 21a of the main sheet 10 overlap each other by the distance between the pair of through holes. be able to. As a result, it is possible to prevent the second outer peripheral edge 22 of the adjacent sheet 10 from coming off between the front branching portion 21a and the back branching portion 21b of the present sheet 10, and to press the surface of the sheet 10 Even if the sheet 10 is displaced by the action of the above, it is possible to suppress the overlap between the first outer peripheral edge 21 and the second outer peripheral edge 22 of the sheet 10. Furthermore, by inserting the pair of insertion members 70b of the clamp 70 through the pair of through holes formed side by side, the insertion member 70b of the clamp 70 is compared with the case of inserting the insertion member of the clamp through one through hole. The rotation of the sheet 10 around the center can be suppressed. For this reason, it can suppress that the outer periphery 21 and 22 of the sheet | seat 10 moves, and can further suppress that a clearance gap produces between adjacent sheet | seats 10. FIG.

  In addition, this invention is not limited to the description content of the said embodiment, For example, you may implement as follows.

  In the said embodiment, a pair of through-hole (a pair of eyelet 31) formed in the 2nd outer periphery 22 in the sheet | seat main body 20 of the 2nd curing sheet 10, and the front branch part 21a in the 1st curing sheet 10 A pair of through-holes (a pair of eyelets 31) formed on each other are overlapped, and after inserting the insertion member 70b of the clamp 70 into these through-holes, the surface fasteners 41 and 42 are brought into close contact and fixed. However, the order of these can be reversed.

  In the above embodiment, the through holes formed in the second outer peripheral edge 22 and the front branching portion 21a in the seat body 20 are formed as a pair side by side in the short direction of the seat body 20, but the pair A single through hole may be formed at the center of the through holes. Even in this case, a plurality of curing sheets 10 can be installed side by side at the same intervals as in the above embodiment.

  In the above embodiment, the hook and loop fasteners 41 and 42 include the second outer peripheral edge 22 of the sheet main body 20 and the inner peripheral portion 23 on the inner peripheral side thereof at both ends and the center in the longitudinal direction of the sheet main body 20. Although the back branch portion 21b is provided so as to be fixable, the surface fasteners 41 and 42 may be provided at predetermined intervals at positions different from these in the longitudinal direction of the seat body 20. Moreover, the continuous surface fasteners 41 and 42 can also be provided over the full length of the sheet | seat main body 20 in the longitudinal direction.

  In the above embodiment, in order to avoid interference between the back branch portion 21b of the sheet 10 and the insertion member 70b of the clamp 70, the back branch portion 21b of the sheet body 20 is connected to the front branch portion 21a in the longitudinal direction of the sheet body 20. Although only the inner side of the through hole formed in the end portion 21c and the end portion 21d in the longitudinal direction is provided, the back branching portion 21b of the sheet body 20 is arranged in the longitudinal direction of the sheet body 20 as shown in FIG. The through hole may be formed at a position where it is overlapped with the through hole formed in the front branch portion 21a. In this case, the curing sheet 110 is fixed by inserting the insertion member 70b of the clamp 70 into the through hole formed in the front branching portion 21a and the through hole formed in the back branching portion 21b. be able to. Even with such a configuration, the sheet 110 can be installed by the clamp 70 without any problem. Furthermore, since the back branching portion 21b of the sheet body 20 can be pulled in the longitudinal direction, it is possible to prevent a gap from being generated between the second outer peripheral edge 22 of the adjacent sheet 110 and the back branching portion 21b of the main sheet 110. can do. The surface fasteners 141a and 142a and the surface fasteners 141b and 142b are provided at both ends of the sheet body 20 in the longitudinal direction. Further, since the back branch portion 21b is fixed by the clamp 70 in contact with the second outer peripheral edge 22, it is more than the surface fasteners 141a and 142a, the surface fasteners 141b and 142b, and the front branch portion 21a of the back branch portion 21b. The portion protruding to the outer peripheral end side can also be omitted.

  In the above embodiment, both ends and intermediate portions of the strings 51a and 51b are fixed to the sheet main body 20, but only both ends of the strings 51a and 51b can be fixed to the sheet main body 20.

  In the said embodiment, string 51a, 51b is the through-hole formed in the edge parts 22c and 22d of the longitudinal direction of the 2nd outer periphery 22 in the sheet | seat main body 20, and the edge parts 21c and 21d of the longitudinal direction of the front branch part 21a. Although the eyelet 31 is formed in parallel with the line segment connecting each other and shorter than the parallel line segment, the eyelet 31 can be formed in the same length as the parallel line segment. Even in such a case, when a force that pushes the surface of the curing sheet 10 is applied, the strings 51a and 51b are stretched, so that tension can be generated in the strings 51a and 51b. . Note that the strings 51a and 51b can be omitted.

  In the above-described embodiment, the surface fastener 41 is provided in a portion of the first outer peripheral edge 21 that protrudes to the outer peripheral side of the front branching part 21 a of the back branching part 21 b, and the inner peripheral part on the inner peripheral side of the second outer peripheral edge 22. Although the surface fastener 42 is provided on the first outer peripheral edge 21, the surface fastener 41 is provided on a portion of the first outer peripheral edge 21 that overlaps the front branching portion 21 a, and the surface fastener 42 is provided on the second outer peripheral edge 22. You can also. In this case, you may abbreviate | omit the part protruded to the outer peripheral end side rather than the front branch part 21a of the back branch part 21b.

  In the above embodiment, one pair of eyelets 31 is attached to one end portion in the longitudinal direction of the sheet body 20 and four pairs of eyelets 31 are attached to the other end portion. can do.

  In the above embodiment, the first outer peripheral edge 21 extending in the longitudinal direction is formed with the front branching portion 21a and the back branching portion 21b that respectively extend to the outer peripheral end side and branch into two sheets. It is also possible to form the same front branch portion and back branch portion on the outer peripheral edge 26 on the short side extending in the direction. In this case, when a plurality of curing sheets are arranged side by side in the longitudinal direction, it is possible to suppress the occurrence of a gap between the outer peripheral edges 26 extending in the short direction. In addition, the outer peripheral edge 26 extending in the short direction has a deformation amount when a force that presses the surface of the curing sheet 10 is applied as compared with the first outer peripheral edge 21 and the second outer peripheral edge 22 extending in the longitudinal direction. It becomes small and it is hard to produce a clearance gap between the outer periphery 26. Therefore, the surface fastener may be omitted as a configuration in which the outer peripheral edge 26 of the lower sheet is sandwiched between the front branch portion and the back branch portion of the upper sheet.

  In the said embodiment, although the sheet | seat 10 for curing was formed corresponding to the dimensional standard of 1800 mm x 5400 mm, it can also be formed corresponding to other dimensional standards, such as 1800 mm x 3600 mm, for example. In this case, it is desirable to appropriately adjust the number of hook-and-loop fasteners 41 and 42 and the number of locations for fixing the strings 51a and 51b according to the dimensions of the curing sheet.

  In the above embodiment, both ends of the front branching portion 21 and both ends of the second outer peripheral edge 22 are fixed by the clamps 70 in the longitudinal direction of the seat body 20. 2 You may make it provide the hook-and-loop fastener 41,42 etc. which fix the center part of the outer periphery 22 supplementarily.

  In the said embodiment, the part including the 2nd outer periphery 22 of the sheet | seat main body 20 in the adjacent curing sheet 10 and the inner peripheral part 23 of the inner periphery side and the back branch part 21b in this curing sheet 10 were piled up. Although the surface fasteners 41 and 42 are employed as the structure to be fixed in a state, other fixing structures such as buttons that are engaged and fixed to each other may be employed.

  In the said embodiment, although the sheet | seat 10 for curing was fixed with the clamp 70, if it is a fixing device which has an insertion member which can be penetrated to the through-hole (eyelet 30) formed in the sheet | seat 10 for curing, other A fixing device can also be employed. In addition, the curing sheet 10 can be installed in other facilities as well as the scaffolding at the construction site.
