Description

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a sheet for suppressing leakage of paint, fine particles, etc., and forming a work space that is less susceptible to the effects of weather, for example, when painting a building.

2. Description of the Related Art Various protective sheets have been proposed to prevent paint from scattering around a building when the building is painted. Two adjacent sheets are connected to each other by tying them together by passing a string or the like through the eyelets of each sheet, but there is a risk that the paint may scatter from the gap between the sheets. From the viewpoint of preventing the paint from scattering from such a gap, a technique of providing a sheet member overlapping the gap is known.

From the viewpoint of strict observance of the construction period or shortening of the construction period, it is desired to form a work space in which work can be continued even in bad weather such as rain and strong wind.

When repainting a building, blasting is performed before applying new paint. Blasting is a process in which fine abrasives are sprayed toward the surface of a building to remove paint, rust, and the like adhering to the building. When such blasting is performed, the paint and rust removed from the building, as well as the abrasive that collides with the surface of the building, may turn into fine particles and adversely affect the environment. Therefore, even in bad weather, it is desired to suppress leakage of paint, fine particles, etc. from the work space surrounding the building to the outside.

In one example, pitch P is 200 mm, pitch P' is 100 mm and spacing D is 100 mm.

The second joint J12 between the main sheet 10 and the second belt-shaped member 12 is formed continuously and linearly along the second direction Y from the upper side TS to the lower side BS. A second region 102 of the main sheet 10 from the second joint J12 to the second side S2 is a strip-shaped region extending in the second direction Y, and a portion of the strip-shaped member 12 extends on the back side of the second strip-shaped member 12. positioned. The second region 102 of the main sheet 10 and the second strip member 12 constitute a second connecting portion C2 for connecting with another sheet.

The width W2 from the second joint J12 to the second side S2 is greater than the width W4 from the second joint J12 to the fourth side S4 (W4<W2). That is, the second region 102 of the main sheet 10 is wider than the second belt-shaped member 12 and extends outside the fourth side S4 of the second belt-shaped member 12 by the difference W24 between the width W2 and the width W4. ing. The difference W24 is the same as the difference W13.

Next, an example of use of the sheet 1 will be described.

A work space for painting a building is formed by attaching a plurality of sheets to a temporary frame surrounding the building. The frame is assembled by vertically and horizontally connecting rod-shaped members such as single pipes. The sheet 1 described above is used to cover the sides of the working space. At this time, the seat 1 is attached so that the inner surface of the main seat 10 faces the building and the frame. The upper side TS of the main sheet 10 is located on the ceiling side of the frame. The lower side BS of the main seat 10 is located on the ground side. A plurality of sheets 1 arranged in the horizontal direction are connected to each other at respective first connecting portions C1 and second connecting portions C2, but it is not assumed that the plurality of sheets 1 are connected in the vertical direction.

Next, a method for connecting two sheets 1 will be described with reference to FIG.

FIG. 2 is a diagram showing a process of connecting the first connecting portion C1 of the seat 1-1 and the second connecting portion C2 of the seat 1-2. In FIG. 2, a left seat 1-1 and a right seat 1-2 have the same shape as the seat 1 shown in FIG.

First, as shown in the upper part (A) of FIG. 2, the first region 101 of the main sheet 10 in the sheet 1-1 and the second region 102 of the main sheet 10 in the sheet 1-2 are turned over, and the sheet 1-1 is turned over. The third side S3 of the first belt-shaped member 11 and the fourth side S4 of the second belt-shaped member 12 on the sheet 1-2 are brought into contact with each other, the binding member B1 is passed through the third eyelet E3 and the fourth eyelet E4, and the binding member B1 unite the

Subsequently, as shown in the middle part (B) of FIG. 2, the first area 101 of the sheet 1-1 is placed on the back surface of the first strip member 11, and the second area 102 of the sheet 1-2 is placed on the first strip member 11. and overlaid on the back surface of the second belt-shaped member 12 . As a result, the second region 102 overlaps the abutting portion of the first belt-shaped member 11 and the second belt-shaped member 12, and also overlaps the third eyelet E3, the fourth eyelet E4, and the binding member B1.
Then, the first side S1 of the first region 101 of the sheet 1-1 and the second side S2 of the second region 102 of the sheet 1-2 are brought into contact with each other, and the binding member B2 is passed through the first eyelet E1 and the second eyelet E2. , binding member B2. The binding members B1 and B2 are, for example, strings, but may be wires, binding bands, or the like. At this time, the first belt-shaped member 11 overlaps the abutting portion between the first region 101 and the second region 102, and also overlaps the first eyelet E1, the second eyelet E2, and the binding member B2.

Through the steps up to this point, the two sheets 1-1 and 1-2 are connected to each other. In the middle figure, the rod-shaped member R forming part of the frame is positioned on the back side of the abutting portion between the first region 101 and the second region 102 as indicated by the two-dot chain line.

Subsequently, as shown in the lower part (C) of FIG. 2, the binding member B2 passed through the first eyelet E1 and the second eyelet E2 is wound around the rod-shaped member R to bind the binding member B2. As a result, the sheets 1-1 and 1-2 are connected to the rod-shaped member R.
A series of operations described with reference to FIG. 2 can be performed on the inner surface side of the seat 1 .

FIG. 3 is a cross-sectional view schematically showing a state in which the sheets 1-1 and 1-2 are connected.
FIG. 3A shows a cross section along the first eyelet E1 and the second eyelet E2 (a cross section along the first straight line L1 in FIG. 1). (B) of FIG. 3 shows a cross section along the third eyelet E3 and the fourth eyelet E4 (a cross section along the second straight line L2 in FIG. 1).

As described above, the first eyelet E1 and the second eyelet E2 are arranged staggered from the third eyelet E3 and the fourth eyelet E4. Therefore, the third eyelet E3 and the fourth eyelet E4 do not exist in the cross section shown in FIG. 3A, and the first eyelet E1 and the second eyelet E4 do not exist in the cross section shown in FIG. There is no eyelet E2. In the cross section shown in FIG. 3A, the first region 101 and the second region 102 are connected by the binding member B2, and in the cross section shown in FIG. Since the two belt-shaped members 12 are connected by the binding member B1, the separation between the first belt-shaped member 11 and the second belt-shaped member 12 is suppressed, and the first region 101 and the second region 102 are prevented from coming into contact with each other. Separation of parts is suppressed.

Therefore, almost no undesired gap is formed between the two sheets 1-1 and 1-2 that are connected, and the blowing of wind into the work space and the infiltration of rainwater are suppressed, and the work is not affected by the weather. work can be continued. In addition, even in bad weather, leakage of fine particles generated by blasting before painting and leakage of paint during painting can be suppressed. Therefore, pollution of air, water, and soil is suppressed during painting work, and it is possible to contribute to environmental conservation.

Further, as described with reference to FIG. 1, the difference W13 between the width of the first belt-shaped member 11 at the first connecting portion C1 and the width of the first region 101 is the width of the second belt-shaped member 12 at the second connecting portion C2. and the width of the second region 102 . Therefore, bending of the inner first region 101 and second region 102 is suppressed, and bending of the outer first strip member 11 and second strip member 12 is suppressed. As a result, almost no undesired space is formed between the first region 101 and the second region 102 and the first belt-shaped member 11 and the second belt-shaped member 12, and a route through which the paint and fine particles can leak is blocked. be done.

Moreover, the sheet 1 is formed using a non-mesh sheet made of synthetic resin, and does not have through holes other than the eyelets. For this reason, compared with non-woven fabrics and mesh sheets, it is superior in waterproofness, and even in rainy weather, the infiltration of moisture into work spaces and the adhesion of moisture to buildings are suppressed.
In addition, the sheet 1 has no through-holes other than the eyelets through which the paint and fine particles can leak, and in addition, the first connecting portion C1 and the second connecting portion C2 have a double structure of the main sheet and the belt-like member. , the eyelets provided on the first connecting portion C1 and the second connecting portion C2 overlap the main sheet or the belt-like member. Therefore, leakage of paint or fine particles from the eyelet is suppressed.

In addition, since the material of the sheet 1 is different from a material that absorbs paint such as a non-woven fabric, it is possible to omit the trouble of replacing it periodically, and moreover, it can be reused many times, resulting in the generation of waste. is suppressed.

Also, the first belt-shaped member 11 and the second belt-shaped member 12 are joined to the same surface of the main sheet 10 . Therefore, when manufacturing the sheet 1, the first belt-shaped member 11 and the second belt-shaped member 12 are joined without turning over the large main sheet 10, and the manufacturing work of the sheet 1 can be simplified.
Moreover, the sheet 1 is made of a material that is thinner and lighter than the soundproof sheet, so that even if the size is increased, the sheet 1 is not bulky and can be easily carried.

Next, another sheet of the present invention will be described.

The fifth eyelet E5 and the sixth eyelet E6 are positioned, for example, on a straight line L3 parallel to the first side S1.

A straight line L11 passing through the fifth side S5 and parallel to the fifth side S5 and a straight line L12 passing through the sixth side S6 and parallel to the sixth side S6 are positioned between the two adjacent first eyelets E1. ing. These straight lines L11 and L12 are also located between two adjacent second eyelets E2.

In the example shown in FIG. 4, two first wrapping members 21 are provided between the first joint J11 and the second joint J12, but the present invention is not limited to the illustrated example. For example, three or more first wrapping members 21 arranged at intervals in the second direction Y may be provided between the first joint J11 and the second joint J12. A single wrapping member 21 may be provided.

Such a sheet 2 is used, for example, to cover the top surface of the working space, but it may be used to cover the side surfaces similarly to the sheet 1 .

FIG. 5 shows a state in which the rod-shaped members forming the frame and the sheet 2 are overlapped. A rod-shaped member RX extending in the first direction X and a rod-shaped member RY extending in the second direction Y are connected by a connector J.

Thereby, the seat 2 is connected to the rod-shaped member RX.

According to such a sheet 2, it is possible to connect the sheet to the rod-shaped member more firmly than when the sheet is connected to the rod-shaped member with a binding member such as a string. Further, when the sheet is connected to the rod-shaped member with a string, the sheet may be lifted up between the strings. Since the joint J21 between the sheet 10 and the first wrapping member 21 is formed in a belt-like shape parallel to the rod-shaped member, the sheet 2 can be prevented from rising from the rod-shaped member. As a result, even in bad weather such as strong winds, the sheet 2 is firmly connected to the rod-shaped member, so that the two sheets 2 connected to each other by the first connecting portion C1 and the second connecting portion C2 can be separated from each other. , almost no gap is formed. Therefore, the blowing of wind into the work space and the infiltration of rainwater are suppressed, and the work can be continued regardless of the weather. In addition, leakage of fine particles, paint, etc. can be suppressed.
Moreover, since the rod-shaped member is covered with the first wrapping member 21, the rod-shaped member can be protected.
Furthermore, when the sheet is connected to the rod-shaped member by a string, the load may be concentrated on the joint portion between the sheet and the string, resulting in breakage of the sheet. Since the one wrapping member 21 is joined to the main sheet 10 at the belt-like joining portion J21, the load is dispersed and damage to the sheet 2 can be suppressed.

Further, the rod-shaped member RY and the connector J overlap on the rear side of the first side S1 and the second side S2, but none of the eyelets overlaps the connector J. As shown in FIG. Therefore, when the two sheets 2 are connected to each other at the first connecting portion C1 and the second connecting portion C2, the connecting tool J does not become an obstacle, and the work can be performed smoothly.
