Description

[Technical Field]

[0001] The present invention relates to a curing sheet and a method for installing the curing sheet. [Background technology]

[0002] When repairing or repainting the roof or exterior walls of a building such as a house, first scaffolding is erected around the building, and then a high-pressure washer or similar device is used to high-pressure wash the roof, gutters, walls, etc. After that, the water used for washing has dried before repairs or painting can be carried out.

[0003] When high-pressure washing is carried out, cleaning water, dust, dirt, etc. are scattered. In addition, repair parts and work tools may fall, and to prevent these from scattering and causing trouble to neighboring buildings, it is common to cover the perimeter of the scaffolding with protective sheets.

[0004] Regarding protective sheets, for example, Patent Document 1 describes a sheet that can be stretched across multiple legs of scaffolding in a horizontal direction to prevent paint from scattering. Holes 16 are drilled around the periphery of the sheet to pass through strings to fasten the sheet to the scaffolding legs 4, etc. [Prior art documents] [Patent documents]

[0005] [Patent Document 1] Japanese Patent Application Publication No. 2018-053509 Summary of the Invention [Problem to be solved by the invention]

[0006] Conventional protective sheets are large and heavy, and because they are tied to scaffolding supports with string, setting them up and removing them is extremely labor-intensive and time-consuming.

[0007] The present invention has been made in consideration of the above circumstances, and aims to provide a curing sheet that is easy to install and remove. [Means for solving the problem]

[0008] The present application includes a number of means for solving at least part of the above problems, examples of which are as follows.

[0009] In order to solve the above problems, one aspect of the present invention is a protective sheet comprising a rectangular sheet body having a first side and a second side that form corners, a plurality of rod-shaped members arranged parallel to and spaced apart along the length of the first side on the sheet body, and a plurality of mounting members arranged at intervals on the edge of the sheet body along the length of the first side.

[0010] The rows of the plurality of rod-shaped members may be arranged in a plurality of stages in the length direction of the second side.

[0011] A space shorter than the entire length of the rod-shaped member may be provided between the plurality of steps.

[0012] The protective sheet may include a plurality of mounting members arranged at intervals on the edge of the sheet body along the length direction of the second side.

[0013] The first side can be longer than the second side, and when the protective sheet is in use and placed on scaffolding, the first side can be placed horizontally and the second side can be placed vertically.

[0014] The spacing between adjacent rod-shaped members can be an integer multiple of the spacing between the supports of the scaffolding on which the protective sheet is installed.

[0015] The protective sheet can be folded into a roll by folding it in the length direction of the second side, setting mountain folds or valley folds in the space, and rolling it in the length direction of the first side around the rod-shaped member as a core.

[0016] Another aspect of the present invention is a method for installing a curing sheet, the curing sheet comprising a rectangular sheet body having first and second sides that form corners, a plurality of rod-shaped members arranged parallel to the sheet body at intervals along the length of the first side, and a plurality of mounting members arranged at intervals on the edge of the sheet body along the length of the first side, the method comprising folding the curing sheet in the length direction of the second side and winding the sheet in the length direction of the first side around the rod-shaped members as a core, to form a roll, and attaching the mounting members to the beams of the scaffolding with the corner formed by the first side and one of the second sides of the curing sheet in the rolled-up state aligned with the corner formed by the support and beam of the scaffolding, and as the rolled curing sheet is unrolled laterally, the mounting members are attached to the beams as needed and extended to the other second side, and the curing sheet in the folded state is unfolded downward.

[0020] An embodiment of the present invention will be described below with reference to the drawings. In all drawings illustrating each embodiment, the same components are generally designated by the same reference numerals, and repeated description thereof will be omitted. In the following embodiments, the components (including element steps, etc.) are not necessarily essential unless otherwise specified or considered to be clearly essential in principle. Furthermore, when the terms "consisting of A," "made of A," "having A," or "including A" are used, other elements are not excluded unless otherwise specified, specifically referring to only that element. Similarly, in the following embodiments, when referring to the shape, positional relationship, etc. of components, etc., the term includes those that are substantially similar or similar to the shape, etc., unless otherwise specified or considered to be clearly essential in principle.

[0021] <Regarding the Curing Sheet 10 According to an Embodiment of the Present Invention> 1 shows an example of the installation of a protective sheet 10 according to one embodiment of the present invention. The protective sheet 10 is used to cover the periphery of a work scaffold 2 in order to prevent cleaning water, dust, dirt, etc. from scattering when repairing or repainting the roof or exterior walls of a building 1 such as a house.

[0022] 2 shows an example of the configuration of the front side of the protective sheet 10 (the surface opposite to the back side that contacts the scaffolding 2). The protective sheet 10 comprises a sheet body 11, rod members 12, and mounting members 13. Note that the protective sheet 10 may also be installed upside down so that the front side contacts the scaffolding 2.

[0023] The sheet body 11 is made of a thin, lightweight, strong, and highly waterproof cloth-like material such as nylon. In terms of weight, a material lighter than a so-called blue tarp (made of polyethylene) is used. By reducing the weight of the protective sheet 10, the workability of installation and removal can be improved. The sheet body 11 may also be made of a mesh-like material.

[0024] The sheet body 11 is a rectangle in which the width of the first side, which is the length in the X direction, is longer than the length, which is the length in the Y direction. The width of the sheet body 11 is formed to be an integral multiple of the spacing between the supports 21 of the scaffolding 2 (standardized to 1800 mm), specifically, two or more times the spacing.

[0025] The vertical width of the sheet body 11 is shorter than the horizontal width and is formed to be less than half of the horizontal width. The vertical width of the sheet body 11 is sufficient to cover the side of the roof from the second floor of a typical house, and this length is sufficient to prevent the splashing of cleaning water, etc. In this embodiment, the horizontal width of the sheet body 11 is formed to be 7200 (= 1800 × 4) [mm] and the vertical width is formed to be 3000 [mm].

[0026] By forming the width of the sheet body 11 to be an integer multiple of the spacing between the supports 21 of the scaffolding 2, the number of times that the protective sheet 10 needs to be climbed up and down the scaffolding 2 when being installed on the scaffolding 2 can be reduced, improving the workability of installation.

[0027] The rod members 12 are made of a lightweight and sturdy material such as aluminum alloy, carbon, or plastic. The rod members 12 are arranged in parallel at intervals corresponding to the intervals between the posts 21 of the scaffolding 2 and are fixed to the sheet body 11. Two rod members 12 are associated with each post, and a space shorter than the length of the rod members 12 (200 mm in this embodiment) is provided between the two rod members 12. While rod members 12 are required on the second left and right sides of the sheet body 11, they may be provided corresponding to all of the posts 21 in the horizontal middle portion of the sheet body 11, or, for example, the rod member 12 corresponding to the central post 21 may be omitted. In this embodiment, the rod members 12 are provided in two rows spaced apart vertically, but the number of rows may be three or more.

[0028] The rod member 12 may be fixed to the sheet body 11 by, for example, sewing it with a string or the like, covering all or part of the rod member 12 with a piece of fabric sewn to the sheet body 11, or by bonding it with an adhesive. Alternatively, the rod member 12 may be stored in a bag-like portion formed in the sheet body 11.

[0029] By providing the rod members 12 on the sheet body 11, when the protective sheet 10 is installed, they function as a framework and weight for the protective sheet 10, preventing the protective sheet 10 from being blown up by the wind.

[0030] When removing the protective sheet 10, a mountain fold or a valley fold can be set in the space between the two rod members 12 for the same support, allowing the protective sheet 10 to be folded vertically. This can also function as a core when rolling up the protective sheet 10 horizontally, improving the workability of rolling up.

[0031] The mounting member 13 is made of a strip-shaped member and a hook-and-loop fastener, and is provided on the edges (top edge and left and right side edges) of the sheet main body 11. The mounting member 13 is wrapped around the supports 21 or beams 22 (Fig. 7) of the scaffolding 2 and secured with the hook-and-loop fastener, thereby installing the protective sheet 10 on the scaffolding 2. As an example, the mounting member 13 is a strip-shaped member, and one end in the longitudinal direction is sewn to the edge of the sheet main body 11, with a hook region on one end and a loop region on the other end. Note that the fastening means for the mounting member 13 is not limited to hook-and-loop fasteners, and may be snap buttons, buckles, tape adjusters, etc., as long as it is easy to attach and detach. Eyelet rings may be provided on the edges of the sheet main body 11, and fastening means such as hooks or tie wraps may be used.

[0032] <How to fold the protective sheet 10> 3 to 6 show an example of a method for folding the protective sheet 10. From a safety standpoint, it is desirable to fold the protective sheet 10 on the ground after removing the entire protective sheet 10 from the scaffolding 2. However, in cases where it is not possible to ensure sufficient working space, the protective sheet 10 may be gradually removed from the scaffolding 2 and folded on the scaffolding 2.

[0033] Fig. 3 shows the protective sheet 10 in an unfolded state. First, as shown in Fig. 4, the shorter vertical side of the protective sheet 10 is folded in half. Next, as shown in Fig. 5, the sheet body 11 is rolled up from one end of the longer horizontal side of the folded protective sheet 10 toward the other end (from the right end to the left in this figure) around the rod member 12 as a core. Finally, as shown in Fig. 6, the sheet body 11 is rolled up until the entire sheet is in a roll shape.

[0034] <How to install the protective sheet 10> 7 and 8 show an example of a method for installing the curing sheet 10. First, as shown in Fig. 7, the corners between the top edge and one side edge of the curing sheet 10 in the folded state shown in Fig. 6 are aligned with the corners of the support 21 and the beam 22, and at least the mounting member 13 on the top edge is attached to the beam 22. As the sheet is unrolled laterally, the mounting member 13 on the top edge is attached to the beam 22 as needed, and the sheet is extended to the other side edge. Next, as shown in Fig. 8, the double-folded curing sheet 10 is unfolded downward. Then, as necessary, the mounting members 13 on the side edges of the curing sheet 10 are attached to the support 21.

[0035] As described above, the protective sheet 10 according to this embodiment can be easily folded, making it easy to move onto the scaffolding 2 or to load onto a vehicle, etc. Furthermore, the protective sheet 10 can be easily installed on the scaffolding 2.

[0036] The present invention is not limited to the above-described embodiment, and various modifications are possible. For example, the above-described embodiment and modifications have been described in detail to clearly explain the present invention, and the present invention is not necessarily limited to those having all of the described configurations. Furthermore, it is possible to replace part of one modification with another modification, or to combine modifications. [Explanation of symbols]
