Description

[Detailed description of the invention]

0001

[Industrial Application Field] The present invention is a sheet for construction work or a sheet for preventing paint scattering used at construction sites such as new construction, demolition, or renovation of buildings or at painting sites, or a sheet for advertising display used in outdoor advertisements, etc. The present invention relates to a sheet tensioning tool for tensioning a sheet such as, a sheet to be tensioned by such a sheet tensioning tool, and a mounting adjustment tool for mounting the sheet tensioning tool to a framework such as a scaffold.

0002

2. Description of the Related Art For example, at a construction site, a scaffold is provided surrounding the building, and a sheet is stretched around the scaffold. Conventionally, when this sheet is stretched, the unit sheets or the sheets and the scaffolding are connected by successively passing ropes or wires through eyelet holes provided in each sheet.

0003

By the way, passing a rope through the eyelet holes and stretching the sheet in this way is extremely inefficient and takes a lot of time. Furthermore, such a connection using a rope requires the preparation of a unit sheet with eyelet holes formed therein, and the unit sheet itself has to be expensive, which is not very satisfactory. Such problems similarly occur in sheets stretched at painting sites and advertising display sheets used in outdoor advertisements.

The present invention has been made in view of the above-mentioned points, and its object is to provide a sheet tensioning tool that can extremely easily perform sheet tensioning, and a sheet tensioning tool that can be stretched using this tensioning tool. An object of the present invention is to provide an attachment adjustment tool that can adjust the connecting position of a sheet and sheet tensioning tool to a scaffolding or the like.

[0005]

[Means for Solving the Problems] According to the present invention, the above-mentioned object comprises a base and a connecting means provided on the base for connecting the base to a frame for laying a sheet. has a first hole that slidably receives the enlarged portion formed at the outermost edge of the sheet, and communicates with the first hole;
a first slit through which the edge of the sheet connected to the ampullae can be inserted; a second hole that slidably receives another ampulla formed at the outermost edge of the other sheet; This is achieved by a sheet tensioning tool that is formed with a second slit that communicates with the second hole and through which the edge of another sheet connected to the other enlarged portion can be inserted.

According to the invention, the object is further a sheet to be stretched by the above-mentioned sheet stretching tool, comprising:
This can also be achieved by a sheet having bulges at least at the opposing extreme edges.

[0007] According to the present invention, the above object also includes a base;
The base is provided with a connecting means provided in order to connect the base to the sheet tensioning framework, and the base slidably receives the enlarged portion formed at the outermost edge of the sheet. a first hole, a first slit that communicates with the first hole and through which the edge of the sheet connected to the ampullae can be inserted; a second hole that slidably receives the ampulla; a second slit that communicates with the second hole and allows an edge of another sheet connected to the other ampulla to be inserted therethrough; A mounting adjustment tool for attaching a sheet tensioning tool to a framework, which is formed with a third hole and a third slit communicating with the third hole, and is slidable into the third hole. This is achieved by means of a mounting adjustment device having a receiving ampulla and a plate-shaped part which is integrally arranged on this ampulla and can pass through a third slit.

The sheet tensioning tool of the present invention is made of wood,
It may be made of metal or synthetic resin, but from the viewpoint of mechanical strength and light weight, it is preferably made of hard plastic or aluminum, and most preferably aluminum. Further, in order to reduce the weight of the sheet tensioning tool of the present invention, a hollow portion may be formed as long as the mechanical strength allows. On the other hand, the length of the sheet tensioning tool of the present invention may correspond to the length of the long side and short edge of the sheet to be applied; The length may be sufficiently shorter than the length of , and a plurality of such short sheet tensioning tools may be applied to each adjacent edge of both sheets to tension the sheets. Particularly when the length of the edge of the sheet is several meters or more, it is recommended to connect the adjacent edges of both sheets using the required number of sheet tensioning tools, which are about 1 meter long at most.
Sheet tensioning work can be easily performed.

The sheet in the present invention may be a general sheet obtained by extrusion molding, such as a nylon sheet or a vinyl sheet, or a cloth or nonwoven fabric made of natural fibers, chemical fibers, or a combination thereof. It may be a sheet of Further, the sheet in the present invention does not have to be completely dense, and may be a mesh-like sheet called a so-called net.

[0010] The bulk part of the sheet in the present invention is as follows:
The edge of the sheet itself may be formed integrally to bulge out, or the edge of the sheet itself may be rolled up, or even the edge of the sheet may be folded back. The ampulla may be formed by inserting a rope into a loop formed therein. The enlarged portion of the sheet in the present invention does not need to be formed at all the outermost edges of the sheet, but may be formed at least at the opposing outermost edge of the sheet in relation to the sheet tensioning tool used. . Furthermore, it is not necessary to have the ampullae continuously over the entire length of at least the opposing outermost edges, but at least to have the ampullae discretely, in other words, intermittently, at the opposing outermost edges. It is okay to do so. The cross-sectional shape of the main ampullae may be circular, triangular or quadrangular, or even a larger polygon.

The first and second holes formed in the base of the sheet tensioning tool may be through holes that open to the outside at both ends, but at least one end is opened to the outside for insertion of the ampullae. It is sufficient that the hole is open, and therefore, it may be a hole with a closed end and the other end closed. The cross-sectional shapes of the first and second holes are as follows in relation to the shape of the ampullae of the sheet:
It may be circular, triangular, quadrangular, or even more polygonal.

The width of the first and second slits formed at the base of the sheet tensioning tool should be such that the large part of the sheet does not come out through the slits. This will make the sheet tensioning work difficult and there is a risk that the edges of the sheet will be damaged. In order to prevent damage to the edges of the sheet, the portion of the sheet tensioning tool that defines the slit is preferably formed smoothly.

According to the present invention, one of the connecting means comprises a plate-shaped portion integrally formed with the base, and this plate-shaped portion includes:
In one preferred example, a slit is formed through which the string-like body can be inserted.

According to the present invention, another connecting means includes a third hole formed in the base, a third slit formed in the base communicating with the third hole, and a third hole formed in the base. It comprises an enlarged part that is slidably received in the hole, and an attachment adjustment device that is integrally provided with the enlarged part and has a plate-like part that can pass through the third slit, where the main part is inserted. A slit through which the string-like body can be inserted may be formed in the plate-like portion, or a gripping tool that can freely grip the frame member may be attached.

[0015] As the string-like body inserted through the slit in the present invention, a rope, a wire, or a belt with a buckle can be presented as an example, but it goes without saying that other things may be used.

The attachment adjusting tool in the present invention is preferably made of the same material as the sheet tensioning tool;
If the most weight is required here, it may be formed from a material with even greater mechanical strength. The enlarged portion of the present attachment adjustment tool does not need to be formed over the entire length, and may be arranged discretely if mechanical strength permits.

The sheet assembly assembled using the sheet tensioning tool of the present invention is not limited to being applied to construction work, but may also be applied to painting sites or advertising displays, for example.

[0018]

[Operation] In the present invention, the enlarged part of the sheet is inserted into the first hole of the sheet tensioning tool, the enlarged part of the sheet is received in the first hole of the sheet tensioning tool, and the enlarged part of the sheet is received in the first hole of the sheet tensioning tool. Insert the enlarged part of the other sheet into the second hole to receive the enlarged part of the other sheet into the second hole of the sheet tensioning tool, and repeat this operation with the prepared other sheet tensioning tool and the sheet. A sheet assembly can be obtained. When each of the sheet tensioning tools is connected to the sheet tensioning frame via the connecting means, the seat assembly can be firmly held in the frame, and as a result, the central part of the seat assembly will not swell due to wind, etc. This situation can be prevented.

The present invention will be explained in more detail below based on specific examples shown in the drawings. This will make the invention and further inventions clear.

It should be noted that the present invention is not limited to these specific examples in any way.

The semi-cylindrical part 15 has a first through-hole which slidably receives the enlarged part 5 formed at the lowermost edge of the upper sheet 2. It is provided with a hole 17 and a first slit 18 which is connected to the through hole 17 and through which the edge 11 connected to the enlarged part 5 of the upper sheet 2 can be inserted over its entire length. The semi-cylindrical portion 16 includes a second through hole 19 formed opposite to the slit 18 in order to slidably receive the enlarged portion 5 formed at the uppermost edge of the lower sheet 2; A second slit 20 is connected to the through hole 19 and is formed opposite to the slit 18, through which the edge 11 connected to the enlarged portion 5 of the lower sheet 2 can be inserted. Equipped with The sheet tensioning tool 7 receives the enlarged portions 5 of the upper and lower sheets 2 in its through holes 17 and 19, respectively, and connects the upper and lower sheets 2 to each other at their outermost edges.

The seat assembly 1 of this example uses a sheet 2 in which eyelet holes 21 are formed at the left and right edges, and between the adjacent left and right sheets 2, a wire or rope is inserted into the eyelet hole 21. 22 are inserted and interconnected at their edges, the leftmost sheet 2 and the rightmost sheet 2
Here, its left and right edges are connected via ropes 22 to the vertical members of the scaffold.

A slit 23 is formed in the plate-like part 7b of the sheet tensioning tool 7, and a belt 24 with a buckle as a string-like body is inserted through the slit 23. The portion 7b is firmly connected and fixed to the horizontal member 25 of the scaffold, which serves as a frame member for sheet tensioning. In this example, the connecting means is constituted by the plate-shaped portion 7b having the slit 23. As shown in FIG.

As described above, the sheet assembly 1 is assembled around a scaffold at a construction site to prevent construction materials from inadvertently falling onto the road during construction.

In the sheet stretching tools 6 and 7 applied to the present sheet assembly 1, the expanded portions 5 of the sheet 2 are inserted into the through holes 10, 17, and 19 one after another from the ends thereof, and the expanded portions of the sheet 2 are stretched. By simply receiving the portions 5 into the through holes 10, 17, and 19, a large number of sheets 2 can be stretched extremely easily and in a short time to assemble the seat assembly 1. Then, the plate-shaped portion 7b of the sheet tensioning tool 7 is attached to the horizontal member 25 of the scaffold.
As a result, the seat assembly 1 is held on the scaffolding via the sheet tensioning tool 7, so that the center part of the seat assembly 1 may swell due to wind or the like, or the seat assembly 1 may It is possible to avoid situations such as being blown away by the wind.

In the above example, the connecting means was constituted by the plate-shaped portion 7b formed with the slit 23 and integrally molded on the base 7a, but instead of this, the connecting means may be constituted as shown in FIG. good. In FIG. 5, the connecting means of this example includes a base 7

A third slit 52 that communicates with the through hole 51 and is formed over the entire length of the base 7a, an enlarged portion 53 that is slidably received in the through hole 51, and a third slit 52 that is integrally provided with the expanded portion 53. , and an attachment adjuster 55 having a plate-like part 54 through which the slit 52 can be inserted, and the plate-like part 54 has a slit 56 through which the belt 24 (see FIG. 3) can be inserted. The connecting means shown in FIG. 5 has the same effect as the previous connecting means, and also allows the attachment adjustment tool 55 to slide in the A-lateral direction with respect to the sheet tensioning tool 7. By doing so, the connection position of the attachment adjustment tool 55 to the horizontal member 25 of the scaffold can be freely adjusted. If the sheet tensioning tool 7 is further formed with symmetrical through-holes 51a and slits 52a corresponding to the through-holes 51 and slits 52, there is no need to consider the direction during assembly, making it extremely easy to use. Get better. Further, the mounting adjustment tool 55 may be approximately the same length as the sheet tensioning tool 7, or may be sufficiently shorter than the length of the sheet tensioning tool 7; One or more attachment adjusters 55 may be applied to the sheet tensioning device 7 to connect the sheet tensioning device 7 to the cross member 25 of the scaffold.

In the example shown in FIG. 5, the buckled belt 2
The sheet tensioning tool 7 is connected to the horizontal member 25 of the scaffold through a string-like body such as No. 4, but as shown in FIG. The sheet tensioning device 7 may also be connected to a cross member 25 of the scaffold. The gripping tool 61 includes a gripping tool main body 62 to which the plate-shaped portion 54 of the attachment adjustment tool 55 is fixed by welding or the like, and a holding plate 6 connected to the main body 62 via a shaft 63 so as to be rotatable in the direction B.
4, a threaded rod 66 rotatably connected to the main body 62 via a shaft 65 in the C direction, and a nut 67 screwed onto the threaded rod 66. The gripping tool 61 can firmly grip the horizontal member 25 by tightening the nut 67.
While the sheet tensioning tool 7 can be reliably connected to the horizontal member 25 of the scaffold, the gripping state can be easily released by loosening the nut 67 and making the threaded rod 66 and the holding plate 64 freely rotatable. obtain.

In the sheet tensioning tool 7 described above, the slit 1
8. The through holes 17, 19 and the slit 20 are arranged in series in this order. According to this structure, the base 7a of the sheet tensioning tool 7 is exposed and viewed from the outside of the sheet assembly 1. The upper and lower sheets 2 may be separated by the sheet tensioning tool 7, which may be undesirable from the aesthetic point of view. Particularly, when each part of an advertisement, such as a photograph, is printed on the outer surface of each sheet 2 and one advertisement is to be displayed on the entire outer surface of the sheet assembly 1, this advertisement is divided by the sheet tensioning tool 7. Therefore, it may not be satisfactory as an advertisement display body in some cases. The sheet tensioning tool 71 shown in FIG.
2 and an edge 1 that communicates with the through hole 73 and is connected to the enlarged portion 4 of the upper sheet 2.
A first slit 74 is formed in the base 72 so that the sheet 1 can be inserted therethrough, and a first slit 74 is formed in the base 72 to slidably receive the enlarged part 5 formed at the outermost edge of the lower sheet 2. A second through hole 75, a second slit 76 formed in the base 72 so that the edge 11 connected to the enlarged part 5 of the lower sheet 2 can be inserted therein, and a second slit 76 provided in the base 72, It is provided with a plate-shaped portion 77 as a connecting means for connecting the base portion 72 to the horizontal member 25, and further provided with a common slit 78 through which both edge portions 11 of the upper and lower sheets 2 are inserted. In such a seat adjustment tool 71, the hole 73, slits 74, 76, and hole 75 are arranged in this order, and the slits 74 and 76 face each other, and in addition, a common slit 78 is provided. The sheet adjustment tool 71 itself is covered with the sheet 2, and the upper and lower sheets 2 are stretched as if they were continuous, which is extremely preferable for displaying advertisements and the like. Further, in the seat adjustment tool 71, it is preferable to provide a separating protrusion 79 between the slits 74 and 76 so that the enlarged portions 5 are reliably held in the holes 73 and 75.

In the seat assembly 1, the sheets 2 having eyelet holes 21 on the left and right edges are used, and the adjacent left and right sheets 2 are interconnected with ropes 22, and the leftmost sheet 2 and one The sheets 2 on the far right side are each connected to the vertical members of the scaffolding, but as shown in Figure 8, each sheet 2 is prepared with four corners cut out and enlarged portions also formed at the left and right edges. Then, connect the adjacent left and right sheets 2 with the sheet tensioning tool 7 (sheet tensioning tool 71 if necessary), and connect the leftmost sheet 2 and the rightmost sheet 2 with the sheet tensioning tool 6 and the rope 14. The sheet assembly 31 may be constructed so as to be connected to the vertical members of the scaffold, respectively. In this way, eyelet holes in the sheets 2 can be made unnecessary, and the work of connecting the sheets 2 to each other using ropes or wires can also be done. Can be made completely unnecessary. In this case, in order to prevent the sheet tensioning tool 7 or 71 that connects the left and right adjacent sheets 2 from falling, an additional enlarged portion 32 may be formed in the sheet 2, or one end may be closed as described above. A sheet tensioning tool 7 having through holes 17 and 19 is used. And the adjacent sheet 2 on the left and right
The sheet tensioning tool 7 or 71 that connects the scaffolding may be connected to the vertical member of the scaffold via a connecting means.

Further, in the sheet assembly 31 of this example, the separated sheet tensioning tools 6 and 7 are used individually for each sheet 2, and the separate sheet tensioning tools 6 and 7 thus separated are used separately for each sheet 2. Using this may improve workability.

By the way, in the sheet assemblies 1 and 31, the sheet 2 is attached to the horizontal and vertical members of the scaffold via the sheet tensioning tool 6 having the elongated hole 13, but as shown in FIGS. , prepare two mounting adjustment tools 44 consisting of an enlarged portion 41 and a mounting plate portion 43 connected to the enlarged portion 41 and having a long hole 42, and attach the enlarged portion 41 of each mounting adjustment tool 44 to the sheet tensioning tool 7. The sheet tensioning tool 7 is inserted into the through hole 17 from one end, the mounting plate part 43 is passed through the slit 18, and the enlarged part 41 of the mounting adjustment tool 44 is slidably received in the through hole 17. Rope 1 in long hole 42
4 to the horizontal or vertical members of the scaffold.
4 may be tied together, and each of the top, bottom, left and right end sheets 2 may be attached to a scaffold. When such a mounting adjustment tool 44 is used, it is possible that the seat tensioning tool 7
Because it can slide freely against the
This may be preferable because the attachment position to the scaffold via the rope 14 can be adjusted. In addition, in order to reduce the weight, a slit 4 is provided in the enlarged part 41 of the mounting adjustment tool 44.
5 and a hollow portion 46 that communicates with the slit 45 is preferably formed. In this example, two attachment adjusters 44 are used to connect to the scaffold, but instead, one or three or more attachment adjusters 44 may be used to connect to the scaffold.

Further, in the above example, the rope 14 is inserted into the holes 13 and 42 to be attached to the scaffold, but instead of this, the rope 14 may be attached to the scaffold by hooking it to the holes 13 and 42. Alternatively, a belt 24 with a buckle as described above may be used to apply a certain tension so that the seat 2 is stretched in a taut state.

In the example shown in FIG. 8, the corners of the sheet 2 are cut out into square shapes, but as shown in FIG. The sheet 2 may be formed by cutting out a triangular shape. In this way, the portion that is not covered by the sheet 2 can be minimized.

[0036]

As described above, according to the present invention, the sheet tensioning tool has the first and second holes that slidably receive the enlarged portion formed at the outermost edge of the sheet, and the first and second holes. and first and second slits that communicate with the second hole and allow the edge of the sheet connected to the ampullae to be inserted,
By simply inserting the enlarged portions of the sheets into the first and second holes, the sheets can be connected together to obtain a sheet assembly, and the sheet assembly can be formed in a short time. Since each of the sheet tensioning tools can be connected to the sheet tensioning frame via the connecting means, the seat assembly can be firmly held in the frame, and as a result, the central part of the seat assembly can be easily damaged by wind or the like. This can prevent swelling.
