Description

  The present invention relates to a work protection sheet for preventing paint or the like from being scattered around a building during construction or repair work of the building.

  In the painting work of a building, in order to prevent the paint from being scattered, the surroundings of the painted part of the building are covered with a rectangular work protection sheet. In general, such a protective sheet for construction is stretched around a building in a state where it is connected vertically and horizontally to form a large sheet. Here, in the conventional protective sheet for construction, a plurality of connecting holes by eyelet fittings are formed along the outer peripheral edge, and the protective sheet for construction arranged vertically and horizontally is the connecting hole of both protective protective sheets. They are interconnected by binding them through strings or the like.

  Here, in the configuration in which the construction protection sheet is simply interconnected by the outer peripheral connection hole, a relatively large gap is generated in the connection portion of the construction protection sheet, and a lot of paint and the like leaks from the gap. In order to suppress leakage, the building is covered twice with a protective sheet for construction. On the other hand, in order to save the trouble of providing double protective sheets for construction, a cover member (velo) is installed that extends to the outside of the periphery of the sheet body and covers the gap between the connecting parts of the protective sheet for construction. It has been proposed (for example, Patent Document 1).

JP 2012-95423 A FIG.

  In the construction protective sheet described in Patent Document 1, the cover member covers the gap between the construction protective sheets, but the cover member extends to the outside of the seat body, so it is easily bulky. There is a problem that a lot of labor is required for storage and transportation.

  The present invention has been made in view of the present situation, and an object of the present invention is to provide a construction protection sheet that can reduce the gap between the connecting portions without providing a cover member extending outside the seat body.

  The present invention relates to a rectangular construction protection sheet that is connected to each other so as to cover a building, and each side has a plurality of outer sides arranged along the peripheral edge of the sheet main body. A plurality of inner connection holes arranged so as to be substantially parallel to the arrangement of the outer connection holes are provided at positions closer to the inner side than the peripheral edge of the seat body by a predetermined width. The hole and the inner connecting hole are a protective sheet for construction, characterized in that they are arranged over substantially the entire length of each side.

  In such a configuration, the two construction protection sheets are arranged so that the peripheral portions of one side overlap each other by a predetermined width, and the outer connection hole of one construction protection sheet and the other construction protection sheet are arranged. If the inner connection hole of the sheet is connected with a string or the like, the two construction protection sheets can be connected without a gap. For this reason, if the construction protective sheet is connected in the same way vertically and horizontally, a large sheet having almost no gap between the construction protective sheets can be formed. Here, since the construction protection sheet of the present invention does not include a cover member that extends outward, it is less bulky than the construction protection sheet described in Patent Document 1, and is easy to store and transport. There is an advantage of being. Moreover, in the structure of the above-mentioned Patent Document 1, there is a problem that the gaps generated at the four corners of the work protection sheet are difficult to cover with the cover member. Since they can be interconnected in a state where they are stacked vertically and horizontally, there are no gaps at the four corners of the protective sheet for construction.

  The inner connecting holes according to the present invention are desirably arranged at a position closer to the inside by 5 to 20 cm than the peripheral edge of the sheet main body. If the arrangement of the inner connection holes is less than 5 cm from the periphery, depending on the intended use, leakage of paint, etc. may not be completely prevented. If it is 20 cm or more inside from the periphery, the overlapping part of the sheet body is excessive. This is because the cost increases.

  In the present invention, on each side, a strip-like connecting body extending substantially along the entire length of each side is fixed to a position closer to the inner side of the peripheral portion of the sheet body, and substantially parallel to each side. The connecting body includes a fixing portion fixed to the surface of the sheet main body, and a non-fixing portion that is coupled to a side edge of the fixing portion and can be lifted from the surface of the sheet main body. A configuration is proposed in which the hole is formed in the non-fixed portion.

  If the inner connecting hole formed closer to the inner side of the seat body passes through the seat body, paint or the like may leak from the inner connecting hole. In such a configuration, the inner connecting hole passes through the seat body. Therefore, there is no possibility that paint or the like leaks from the inner connection hole.

  Further, in the above configuration, the band-shaped connection body provided on each side is fixed to only one surface of the sheet main body, and one of the pair of band-shaped connection bodies provided on two opposite sides is the above-described one. A configuration is proposed in which the sheet body is fixed to one surface and the other is fixed to the other surface of the sheet body.

  With this configuration, the work protection sheet can be connected vertically and horizontally in the same direction without providing a belt-like connection body on both sides of the sheet body for each side. Can be reduced. Further, even in such a configuration, since all the connecting work of the construction protection sheet can be performed from one side, the construction work of the construction protection sheet is not complicated.

  Further, in the above configuration, the belt-like connecting body is formed by weaving synthetic resin yarn, and the non-fixed portion of the belt-like connecting body has the inner connecting hole continuously along the longitudinal direction. A configuration in the form of a ladder arranged in the above is proposed.

  If both the outer connecting hole and the inner connecting hole are arranged at a relatively wide interval, the connecting portion of the protective sheet for construction tends to be distorted in the arrangement direction of the inner connecting hole and the outer connecting hole. In this case, since the inner connection holes are continuously arranged, there is an advantage that the connection part of the construction protection sheet is hardly distorted.

  Further, in the present invention, a configuration is proposed in which the outer connecting hole is formed by an eyelet fitting disposed at a peripheral edge portion of the seat body. With this configuration, the outer connecting hole can be disposed at a low cost.

  As described above, according to the protective sheet for construction of the present invention, it is possible to reduce the gap between the connecting portions without providing a cover member extending outside the seat body.

It is explanatory drawing which shows the state which connected the protection sheet 1 for 2 sheets of construction in the horizontal direction. It is explanatory drawing which shows the method of connecting the protection sheet 1 for construction vertically and horizontally.

Embodiments of the present invention are illustrated by the following examples.
The construction protection sheet 1 of the present embodiment is a rectangular sheet as shown in FIG. The construction protection sheet 1 shown in FIG. 1 is about 3 m long by 1 m wide, but the vertical and horizontal sizes are not limited to this, and can be appropriately changed depending on the application. The sheet body 2 of the construction protection sheet 1 is constituted by a single mesh sheet. For convenience, in the drawings, the mesh of the sheet main body 2 is expressed coarsely, but the sheet main body 2 has a fine mesh that is difficult for the paint or the like to pass therethrough. A reinforcing material 4 made of synthetic leather is sewn on the entire periphery of the periphery of the seat body 2. A plurality of eyelet fittings 3 are disposed on the peripheral edge of the reinforcing material 4. The eyelet fittings 3 are arranged one by one at the four corners of the sheet body 2 and further arranged at intervals of about 20 cm along each side.

  As shown in FIGS. 1-3, the strip | belt-shaped connection body 5 is each sewn on each side of the sheet | seat main body 2 in about 10 cm inner side position from the peripheral part where the eyelet metal fitting 3 is arrange | positioned. The belt-like connecting body 5 is a belt-like cloth formed by knitting a high-strength synthetic fiber yarn. The belt-like connecting body 5 is sewn on only one side for each side of the sheet main body 2, and the belt-like connecting bodies 5 arranged on two opposite sides of the sheet main body 2 are sewn on different surfaces. The The strip-like connection body 5 disposed on each side of the sheet body 2 is sewn in parallel with the side over the entire length of the side. For this reason, as shown in FIG. 2, the two strip | belt-shaped connection bodies 5 sewn on the single side | surface of the sheet | seat main body 2 are sewn so that one may overlap on the other. The belt-like connecting body 5 includes a fixing portion 9 that is relatively densely woven and continuous in the longitudinal direction, and a ladder-like non-fixing portion 10 that is continuous with the side edge of the fixing portion 9 and continues in the longitudinal direction. The fixed portion 9 is sewn to the sheet main body 2, and the non-fixed portion 10 is raised from the surface of the sheet main body 2. As will be described later, the hole 8 formed by the ladder-like non-fixed portion 10 constitutes the inner connecting hole according to the present invention. It should be noted that an eye mesh (registered trademark) manufactured by Toyonen Co., Ltd. can be used for the strip-like connector 5 according to the present embodiment.

  For example, as shown in FIG. 4, the construction protection sheet 1 is arranged so as to cover the periphery of the building of the tower A during the painting work of the tower A, and powders such as paint leak out to the outside. Can be used to prevent The construction protection sheet 1 shown in FIG. 4 is connected to three supporting members B such as wires arranged around the steel tower A after being connected three vertically and eight horizontally. The one side of the steel tower A is covered. In addition, such a usage method is only one example of use, and the protective sheet for construction 1 of the present embodiment can be used to cover the steel tower A locally as well as the existing protective sheet for construction. Can also be used to cover buildings.

  Below, the connection mechanism of the protective sheet 1 for construction is demonstrated. As shown in FIGS. 1 to 3, two rows of inner and outer connecting holes 7 and 8 are formed along each side of the four sides of the construction protection sheet 1. That is, the outer connecting hole 7 (hereinafter also referred to as the outer connecting hole 7) is formed by the eyelet fitting 3 disposed on the peripheral edge. The inner connecting hole 8 (hereinafter also referred to as the inner connecting hole 8) is formed by the strip-shaped connecting body 5 disposed closer to the inner side than the peripheral edge. The outer connecting holes 7 are circular holes having a diameter of about 1 cm that penetrate the peripheral edge of the sheet body 2, and are formed at intervals of about 20 cm in parallel with the respective sides of the sheet body 2. On the other hand, the inner connecting hole 8 is a rectangular hole having a width of about 1 cm and a length of about 2.5 cm formed in the ladder-like non-fixed portion 10 of the band-shaped connecting body 5 and does not penetrate the sheet body 2. In addition, it is continuously formed in parallel with each side of the sheet body 2 at intervals of about 1 cm.

  When the two protective sheets 1 for construction are connected in the vertical direction or the horizontal direction, the outer connecting hole 7 and the inner connecting hole 8 are connected by the string C. Specifically, after the two construction protection sheets 1 to be connected are juxtaposed in the vertical direction or the horizontal direction, as shown in FIG. Only the outer connection hole 7 and the inner connection hole 8 are brought close to each other. In addition, since the strip | belt-shaped connection body 5 is sewn on the surface which differs in the two sides which the sheet | seat main body 2 opposes, the two protection sheet | seats 1 for construction to connect are the vertical direction or a horizontal direction in the same direction. Just place them side by side.

  Subsequently, as shown in FIG. 5 (b), the outer connection hole 7 of one construction protection sheet 1 and the inner connection hole 8 of the other construction protection sheet 1 are bundled through a string C, and each connection is made. The holes 7 and 8 are connected. 5 (b) shows only the connection between the pair of outer connection holes 7 and the inner connection holes 8, but here, all of the outer connections arranged along one side of one construction protection sheet 1 are shown. The connecting hole 7 is connected to the inner connecting hole 8 of the other construction protection sheet 1. Thereby, the two protection sheets 1 for construction are mutually connected over the full length of a vertical side or a horizontal side.

  Thereafter, as shown in FIG. 5 (c), the outer connection hole 7 of the other construction protection sheet 1 and the inner connection hole 8 of the one construction protection sheet 1 are bundled through a string C, and the respective connection holes. 7 and 8 are connected. Here too, all the outer connection holes 7 arranged along one side of the other construction protection sheet 1 are connected to the inner connection holes 8 of one construction protection sheet 1. Thereby, as shown in FIG. 6, the two construction protection sheets 1 are interconnected on both the front and back sides by the string C in a state where the peripheral portions are overlapped.

  In the above connection method, the work shown in FIG. 5B is carried out from the upper side in the drawing by raising the peripheral edge of one construction protective sheet 1 as shown in FIG. 5B. For example, the work shown in FIG. 5B and the work shown in FIG. 5C can be efficiently performed on the same side of the work protection sheet 1. Moreover, although the said connection method is a typical connection method of the protection sheet 1 for construction of a present Example, you may connect the protection sheet 1 for construction of a present Example other than this connection method. For example, the outer connecting hole 7 and the inner connecting hole 8 may be connected using not only the string C but also other binding tools and fasteners.

  As described above, if the work protection sheet 1 of this embodiment is interconnected in a state where the peripheral edges of each other are overlapped, as shown in FIG. 6, there is almost no gap between the two connecting portions. Leakage of paint etc. from the connecting part of the sheet can be prevented. Further, as shown in FIG. 6, when the construction protection sheets 1 are interconnected in one direction, the strip-shaped connectors 5 positioned at both ends are arranged on different surfaces, and therefore in the same direction. The construction protection sheet 1 in the same direction can be connected to three sheets, four sheets, five sheets, etc. in the same manner. In addition, as shown in FIG. 6, when the construction protection sheet 1 is interconnected in one direction, all the strip-like connectors 5 positioned on one side in the orthogonal direction (vertical direction in the figure) are arranged on one surface side. All the strip-like connection bodies 5 located on the other side in the orthogonal direction are arranged on the other surface side. For this reason, in this embodiment, for example, as shown in FIG. 7, after preparing a plurality of sets of construction protection sheets 1 connected in the horizontal direction, they are juxtaposed in the vertical direction and are mutually connected by the above-described method. If connected, the protective sheet for construction 1 can be connected vertically and horizontally. Therefore, as shown in FIG. 4, when three construction protective sheets 1 are connected vertically and eight horizontally, three sets of eight construction protective sheets 1 connected in the horizontal direction are prepared. Then, they may be connected in the vertical direction. Of course, it is possible to prepare eight sets of three construction protection sheets 1 connected in the vertical direction and connect them in the horizontal direction.

  As described above, the construction protection sheet 1 according to the present embodiment can be connected vertically and horizontally with the respective peripheral portions thereof being overlapped, and therefore, a plurality of construction protection sheets 1 are connected vertically and horizontally without any gap. be able to. Therefore, the construction protection sheet 1 of the present embodiment can appropriately prevent leakage of paint or the like without covering the building twice. In addition, since the construction protection sheet 1 does not include a cover member that extends outward, it is less bulky than the conventional construction protection sheet that prevents leakage by the cover member, and is easy to store and transport. There is an advantage. In particular, in this embodiment, when the construction protection sheet 1 is connected vertically and horizontally, the corners of the four construction protection sheets overlap at the four corners of the construction protection sheet 1. No paint leaks from the four corners of 1. In the present embodiment, the inner connecting hole 8 is formed in the non-fixed portion 10 of the belt-like connecting body 5, and the inner connecting hole 8 does not penetrate the sheet main body 2, so that the paint is passed through the inner connecting hole 8. There is no risk of leaking outside.

  Further, in the present embodiment, since the belt-like connecting body 5 is sewn on different surfaces for the two opposite sides of the sheet main body 2, the belt-like connecting body 5 is sewn on both sides with respect to each side of the sheet main body 2. Even if it is not worn, the construction protection sheet 1 can be interconnected vertically and horizontally in the same direction, and the construction protection sheet 1 can be connected from one side.

  Further, in this embodiment, the inner connection holes 8 are densely arranged in the longitudinal direction by the ladder-like non-adhering portions 10 of the belt-like connection body 5, so that the outer connection holes 7 are made of the inexpensive eyelet fitting 3. Therefore, the outer connecting hole 7 can be connected to the inner connecting hole 8 without distorting the sheet body 2 in the arrangement direction of the connecting holes 7, 8.

  As mentioned above, although the Example of this invention was described, the protection sheet | seat for construction of this invention can add a various change in the range which does not deviate from the summary of not only the form of the said Example but this invention.

  For example, in the construction protection sheet 1 of the above embodiment, the sheet body 2 is composed of one mesh sheet, but the sheet body according to the present invention may be composed of a nonwoven fabric or the like, A plurality of types of sheets may be laminated.

  Moreover, you may comprise the strip | belt-shaped coupling body which concerns on this invention with a strip | belt-shaped petet instead of the structure of an Example.

  Moreover, in the said Example, although the space | interval of the outer side connection hole 7 and the inner side connection hole 8 becomes a common dimension by the upper and lower sides, right and left, the space | interval of the outer side connection hole 7 and the inner side connection hole 8 is a vertical space | interval and right and left side The interval may be different.
