Description

[Detailed description of the device]

[0001]

[Industrial applications]

 The present invention mainly relates to a tension structure of a net-like or cloth-like sheet material stretched at a temporary construction site.

[0002]

[Prior art]

 In general, a sheet-like material is stretched around the scaffolding at a construction site from the viewpoint of danger prevention. An example of this will be described with reference to FIGS. 13 and 14.

In FIG. 13, a walk board 51 forming a scaffold is supported by vertical pipes 52 and horizontal pipes 53, which are assembled in a grid pattern. A sheet-like material 54 as shown in FIG. 14A is provided outside the temporary structure 50. The sheet-like material 54 has a large number of eyelets 55 on the cloth-like portion on the periphery thereof. As shown in FIG. 14 (b), the eyelet 55 has a through hole formed by an annular finishing metal piece 55a. The sheet-like material 54 is stretched by being fixed to the vertical pipe 52 or the horizontal pipe 53 with a cord 56 at the location of the eyelet 55.

[0004]

[Problems to be solved by the device]

 However, if the string 56 is tied, the string 56 gradually loosens due to the weight of the sheet-like object 54 and the external force applied to the sheet-like object 54. Therefore, as shown in FIG. Hangs between. Therefore, a gap S is formed in this hanging portion, and a falling object may fly out, which is not good in appearance. In addition, it is generally troublesome to tie the cord 56, and the work time for attaching and detaching the sheet-like material on the site becomes long.

The present invention has been made in view of the above-mentioned conventional problems, and it is possible to prevent the sheet-shaped material from loosening between the eyelets and to tighten the sheet-shaped material so that the sheet-shaped material can be easily stretched. It is intended to provide a structure.

[0006]

[Means for Solving the Problems]

 In order to achieve the above-mentioned object, the structure common to each claim of the present invention is that the long member is engaged with the long member at a pitch substantially matching the pitch of the sheet-like material along the longitudinal direction of the long member. A member is provided, and the eyelet of the sheet-like material is hooked on the protruding portion of this hooking member.

[0007]

[Action]

 According to the invention of each claim, since the eyelet is hooked on the protruding portion of the hooking member provided on the long material, unlike the case where it is tied with the conventional string, there is no risk of loosening, so the sheet-like object hangs down. Thus, it is possible to prevent a gap from being formed between the eyelets. Further, since the eyelet is hooked on the protruding portion of the hooking member, the work of attaching and detaching the sheet-like object becomes easier than in the case of tying with a conventional string.

 An embodiment of the present invention will be described below with reference to FIGS. As shown in the perspective view of FIG. 1, in this tension structure, a long plate-shaped long member 1 and a metal fixture 2 for fixing an end portion 11 of the long member 1 to a vertical pipe 52, The latch member 3 made of resin mounted in the mounting hole 12 of the long member 1 is used.

As shown in FIGS. 2 (a) and 2 (b), the long material 1 has a pitch substantially matching the pitch of the eyelets 55 of the sheet-like material 54, and the long material 1 has a longitudinal direction L. In addition, for example, about 7 (a plurality of) mounting holes 12 are provided in two rows. The end portion 11 of the long material 1 is provided with a string insertion hole 13 and a separation prevention hole 14. The long member 1 is made of a transparent resin such as polycarbonate or acrylic.

FIG. 3 is a perspective view of the fixture 2 seen from the inside of the temporary structure. As shown in FIG. 3, the end portion 11 of the long member 1 is dropped into the groove 20 of the fixture 2 and fitted therein. The fixture 2 is fixed to the vertical pipe 52 by the clamp 21, as shown in FIGS. 4 (c) and 4 (b). The clamp 21 is provided at the lower end of the fixture 2 via a bracket 22 so as not to interfere with the work of stretching the sheet-like material. A substantially U-shaped fixture main body 23 which is vertically long is fixed to the bracket 22 in advance by caulking or welding.

As shown in FIG. 4C, a leaf spring 24 is provided on the back surface 23 a of the fixture body 23, that is, on the inner side of the temporary structure. A taper pin-shaped detachment prevention tool 25 is fixed to the leaf spring 24. The detachment preventive tool 25 is retracted from the through hole 23b of the fixing tool body 23 by bending the leaf spring 24 in the horizontal direction, allows the elongated member 1 to be inserted, and the spring force of the leaf spring 24 allows By returning and inserting into the detachment prevention hole 14 of the long material 1, the long material 1 is prevented from coming off the fixing tool 2. As shown in FIG. 4 (a), a handle-like stopper 26 is provided on the back surface 23a of the fixture main body 23, and this stopper 26 has a leaf spring 24 more than necessary as shown in FIG. 4 (c). It is designed to prevent bending, so that the leaf spring 24 does not interfere with the work. The stopper 26 is rotatable at the hinge portion 26a.

At the end of the temporary structure 50 of FIG. 1, as clearly shown in FIG. 5, the cord 56 is passed through the cord insertion hole 13 of the elongated member 1 and the elongated member 1 is fixed to the vertical pipe 52. Has been done. Note that this portion may be fixed to the vertical pipe 52 by using a fixing tool having a structure of the left half of the fixing tool 2 in FIG. 3, for example. In this way, the long material 1 is fixed to the vertical pipe 52 by the fixture 2 or the cord 56 of FIG.

The hooking member 3 as shown in FIG. 6A is mounted in the mounting hole 12 of the long member 1 fixed to the vertical pipe 52. Therefore, in the long material 1 of FIG. 1, a large number of hook members 3 are arranged in two rows along the longitudinal direction L with a pitch substantially matching the pitch of the eyelets 55 (FIG. 2) of the sheet. It will be provided.

As shown in FIG. 7, the latch member 3 has a base portion 30 that projects from the attachment hole 12 of the long member 1 to the outside of the temporary structure 50, and a protrusion that projects from the base portion 30 to the inside of the temporary structure 50. The part 31 and the like are integrally formed. The base portion 30 is inserted into the mounting hole 12 which is long in the longitudinal direction L in a posture rotated by 90 ° about the horizontal axis from the mounted state shown in this figure. A leaf spring portion 32 is opposed to the base portion 30. By sandwiching the plate-shaped long member 1 by the leaf spring portion 32 and the above-mentioned base portion 30, the latching member 3 is made into the long member 1. It is removably mounted in the mounting hole 12 of.

In FIG. 6A, the protrusion 31 of the hook member 3 is provided with, for example, a withdrawal prevention piece 31b retractable by resin elasticity in a retract hole 31a formed in the protrusion 31. . As shown in FIG. 8, the eyelets 55 of the sheet-like material 54 are inserted into the hooking member 3 having such a structure, and the eyelets 55 are hooked on the protrusions 31 of the hooking member 3. The detachment prevention piece 31b retracts in the direction of arrow A shown by the broken line when the eyelet 55 is inserted. Thus, the eyelets 55 of the upper edge portion 54a and the lower edge portion 54b of the sheet-like material 54 are the same as those in FIG. 7 except for the portion of the fixture 2 of FIG. Further, it is hooked on the protrusion 31 of the hooking member 3.

The eyelet 55 of the fixture 2 portion of FIG. 3, that is, the eyelet 55 of the corner portion of the sheet-like material 54, is hooked by the hooking protrusion 27 protruding from the fixture body 23 to the back. . The latching protrusion 27 has a large-diameter detachment prevention collar 27a at the tip thereof for preventing the eyelet 55 from detaching. It should be noted that four locking protrusions 27 are provided on one fixture 2.

On the other hand, as shown in FIG. 9, the left and right eyelets 55 along the vertical pipe 52 of FIG. 1 are fixed to the vertical pipe (structural material) 52 in a state where the sheet-like objects 54 are brought close to each other. There is. Note that this fixing may be performed by tying with a string 56 as shown in FIG. 14 (b), or may be performed by using a dedicated fastener 56A shown in FIG.

In the above structure, since the eyelet 55 is hooked on the protruding portion 31 of the hooking member 3 provided on the long member 1 of FIG. 7, unlike the conventional case where the eyelet 55 is tied, there is no risk of loosening. Therefore, it is possible to prevent the sheet-like material 54 from hanging down between the eyelets 55, 55 to form a gap. Therefore, it is possible to prevent objects from jumping out of the temporary structure 50 and improve the appearance.

In the conventional method, as shown in FIG. 1, when the walking board 51 (horizontal pipe 53) and the upper and lower edge portions 54a and 54b of the sheet-like object 54 are displaced from each other, a long string is used. Therefore, it was necessary to connect the eyelet 55 to the horizontal pipe 53 (Fig. 13), and the work was extremely troublesome. On the other hand, with this tension structure, as shown in FIG. 8, it is only necessary to hook the eyelets 55 on the projecting portions 31 of the hooking members 3, so that the work of attaching and detaching the sheet-like material on site is extremely easy. Become.

Further, in this embodiment, since the hooking member 3 can be detachably attached to the long member 1, when the resin hooking member 3 is deteriorated with time, the hooking member 3 is detached. The member 3 can be replaced.

However, in the inventions of claims 2 to 4, the hooking member 3 may be formed integrally with the elongated member 1. As a method of integrally forming the latching member on the long material 1, for example, there is a method of forming the latching member from the long material 1 by pressing and forming the long material 1 made of a light metal. .

Further, as shown in FIG. 1, it is difficult to form a gap between the left and right eyelets 55. Therefore, for the left and right eyelets 55, as in this embodiment, the cord 56 or the exclusive fastening tool is used. By fixing the eyelets 55 to the vertical pipe (structural material) 52 by using the structure, the structure becomes simple and the construction becomes easy.

Further, in this embodiment, as shown in FIG. 4C, the long member 1 is dropped into the groove 20 of the fixture 2 and fitted therein, and the long member 1 is removed by the detachment prevention device 25. Since the detachment from the fixture 2 is prevented, the long material 1 can be securely and easily fixed.

Further, in this embodiment, since the corner eyelet 55 of the sheet-like material 54 shown by the chain double-dashed line in FIG. 3 is hooked on the hooking projection 27 of the fixture 2, the corner eyelet 55 is removed. It is easy to hook.

However, in the inventions of claims 1 to 3, it is not necessary to hook the eyelets 55 at the corners on the hooking protrusions 27 of the fixture 2. For example, the eyelets 55 are connected to each other by a string and the pipes are connected to each other. You may fix to 52, 53 (FIG. 13).

Further, in this embodiment, since the long material 1 of FIG. 1 is made of a transparent resin, the sheet-like material 54 inside the long material 1 can be seen through, so that the entire temporary structure 50 (FIG. 1) can be seen. Becomes the color of the sheet-like material 54, and is therefore aesthetically pleasing. Needless to say, in this invention, the long member 1 may be made of an opaque material such as metal.

Further, as shown in FIG. 2, since the mounting holes 12 are elongated in the longitudinal direction L in this embodiment, even if the pitches of the eyelets 55 and the mounting holes 12 are slightly different, 55 can be hooked on the hooking member 3 of FIG.

In the above embodiment, the eyelets 55 of the upper and lower edges 54a and 54b of the sheet-like material 54 are hooked on the hooking member 3, but in the inventions of claims 1, 3 and 4, the upper and lower edges are not always required. It is not necessary to hook the edge portions 54a and 54b of the above, and for example, the eyelet 55 of the left and right edge portions 54c may be hooked to the hooking member 3.

Further, in the above-described embodiment, an example in which the sheet-like material 54 is stretched along the vertical plane has been described, but in the present invention, when the sheet-like material 54 is stretched in an inclined manner or is stretched horizontally. It also applies when installed.

Further, the detachable hooking member 3 is not limited to the structure shown in FIG. 6A, but the tip 31c of the protrusion 31 may be bent as shown in FIG. 6B, for example. It may have any shape.

Further, the fixture 2 of FIG. 3 is not limited to that of this embodiment, and for example, the fixture 2 shown in FIGS. 10 and 11 may be used. In FIG. 10, a handle 28 of the fixture 2 is rotatably attached to the leaf spring 24 to facilitate bending of the leaf spring 24. Further, as shown in FIGS. 11A and 11C, a tapered surface 25a is formed on the pin-shaped removal preventing tool 25 provided on the leaf spring 24. By doing so, by inserting the taper surface 25a upward like the detachment preventive tool 25 of FIG. 11C, the elongated member 1 can be easily inserted. In addition, in this embodiment, the latching protrusion is not provided.

Next, another example of the long material will be described. In FIG. 12A, the elongated member 1A is provided with a pair of upper and lower groove-shaped mounting rail portions 12A extending in the longitudinal direction L from one end portion 11 to the other end portion 11. As shown in FIG. 12B, the cross-sectional shape of the long material 1A is a bag shape, and is substantially uniform over the entire length of the long material 1A. The latching member 3 has the same structure as that shown in FIG. 6 (a), and the base member 30 and the leaf spring 32 are formed in the vicinity of the mounting rail portion 12A of the long member 1A by the spring force of the leaf spring portion 32. By sandwiching between them, they are slidably mounted along the above-mentioned mounting rail portion 12A. When the sheet-like material 54 is stretched, the locking members 3 are attached to the long material 1A at a pitch that substantially matches the pitch of the eyelets 55. Eyelets 55 of upper and lower edges 54a and 54b of the sheet-like object 54 which are opposed to each other are hooked on the hooking member 3. The other structures are the same as those in the examples of FIGS. 1 to 9, and the same portions or the corresponding portions will be denoted by the same reference numerals and detailed description thereof will be omitted.

In the long member 1A of the embodiment shown in FIG. 12, the locking member 3 is attached to the mounting rail portion 12A extending in the longitudinal direction L. Therefore, the locking member 3 is slid in the longitudinal direction L to be elongated. It can be collected on one of both ends 11 of the material 1A. Therefore, in the event of a strong wind such as a typhoon, the sheet-like object 54 is brought together with the hooking member 3 to the end portion 11 and the sheet-like object 54 is tied to the vertical pipe 52 (FIG. 13) with a string, so that the sheet-like object 54 is formed. It can prevent large forces from working. Therefore, when preparing for a typhoon or the like, the sheet-like materials 54 can be easily gathered together.

The tension structure using the long member 12A in FIG. 12 is similar to the structure in which the curtain is attached to the curtain rail, but the edge portions 54a and 54b of the sheet-like object 54 facing each other are separated. The difference is that the eyelets 55 are hooked, and that the hooking member 3 holds the long material 1A by spring force.

By the way, in this example, the mounting rail portion 12A is configured by a long groove, but the mounting rail portion 12A may be configured by a rail protruding in a T-shaped cross section, for example. The tension structure using the long member shown in FIG. 12 is included in the inventions of claims 2 to 5.

By the way, in each of the above-mentioned embodiments, an example of use in a construction site has been described, but the present invention can also be applied to the installation of a sheet for a civil engineering site or the installation of a net for a fishing industry. You can
