Description

[Detailed Description of the Invention] [Industrial Field of Application] The present invention relates to a sheet-like object locking tool that locks a sheet-like object in a straight line. More specifically, the present invention relates to a sheet-like object fastener for a simple greenhouse such as a vinyl greenhouse or a simple greenhouse that uses a sheet-like object as a roof or side wall.

[Conventional technology] Main cultivation facilities for vegetables, flowers and trees, etc. depend on the cultivar, the income per crop, etc., and in addition to the widespread use of permanent greenhouses such as glass greenhouses and plastic greenhouses (hard film), general Generally, among farmers, so-called vinyl greenhouses, which use cheap so-called pipes as the framework and use soft vinyl as the covering material, are the most popular.

However, vinyl greenhouses have poor durability and need to be replaced with new vinyl every 1 to 2 years, resulting in high costs and troublesome expansion.

By using a hard film with improved weather resistance in place of the above-mentioned vinyl covering material, the durability will be approximately 4 to 6 years, and the above problems can be solved. However, there is a problem of tearing of the hard film.

[Problems to be solved by the invention] Regardless of whether a soft or hard film is used, and when attaching a sheet-like object other than a film such as a tarpaulin to a structure, the requirements required for the fastener are as follows: This means that the sheet can be easily expanded, the locking operation can be performed easily, and there is no damage to the sheet-like object.

Japanese Utility Model Application No. 60-12858 proposes a film stretching device whose main parts are a slit pipe and a holding plate. This film stretching device forms a slit in the house frame pipe, deforms the slit part into an inverted V shape, attaches a holding plate facing the slit part through the film, and attaches the holding plate to the slit part of the house frame pipe. I am planning to fix it with screws.

Although this device has the advantage that it uses few parts and is easy to handle, it uses a slit pipe, which weakens the framework, and there is a risk that the film will tear due to the holes being punched in the stretched portion of the film.

The purpose of the present invention is to improve the above-mentioned deficiencies of the prior art, and to provide a sheet-like object fastening device that can be applied to any of soft, hard, and thick sheet-like objects, does not tear the sheet-like objects, and is easy to handle. We aim to provide the following.

[Means for Solving the Problems] In order to achieve the above object, the present invention has the following configuration.

In other words, in a sheet-like object locking tool that locks the end of a sheet-like object, the locking tool consists of a receiver and a pressing tool, and the receiver can bend the end of the sheet into a U-shape. The cross section of the house has a groove-shaped opening in the depth direction, and the pressing tool presses the U-shaped sheet portion from the outside to the top surface of the outer wall, end surface, top surface of the inner wall, and side surface of the inner wall. and a sheet-like object locking device, which is configured to be pressed and fitted against the lower surface of an inner wall, and the height of the receiver is adjustable by a height adjusting member. It is a ingredient.

The present invention provides a greenhouse house in which a frame constituting the greenhouse house is covered with a sheet made of synthetic resin, etc., and the present invention provides a sheet-like structure that grips one end of the sheet disposed in the depth direction of the framework of the greenhouse house. This relates to a device for securing objects.

The present invention will be explained in more detail.

FIG. 1 is a side view showing an example of a sheet-like object fastening device according to the present invention, and is shown partially in section.

In FIG. 1, a locking tool 1 is connected to a receiving tool 2 and a pressing tool 3.
is its main part.

As shown in FIG. 1, the receiver 2 has an open portion on the upper side, has a cross-section shaped like a square, and has a low protrusion 4 in the center of the bottom. The sheet-like material 5 is
As shown in the figure, the open end of the receiver 2 is bent twice into a U-shape, and a double-sided adhesive tape or adhesive 6 is interposed between the receiver 2 and the open end.

On the other hand, the pressing tool 3 has a cross section that corresponds to the outer shape of the receiver 2, and has a sheet portion that is bent twice in a U-shape along the shape of the receiver 2. Two pieces are provided on each of the left and right sides of the receiver so that they are pressed and fitted against each other. That is, the pressing tool 3 presses the end of the sheet-shaped object bent in a U-shape from the outside against the outer wall upper surface 21, end surface 22, inner wall upper surface 23, inner wall side surface 24, and inner wall lower surface 25 of the receiver, It is configured to be fitted. These pressing tools 3 are made by attaching the sheet-like material to the receiver 2 with double-sided adhesive tape and inserting it into the hollow part of the receiver 2 from the open part of the receiver 2 using a hammer or the like. is pressed and fixed to the receiver 2. In order to prevent the pressing tool from shifting with respect to the receiving tool 2, the terminal end of the pressing tool 3 is fitted with a spring portion 7 that abuts against the protrusion 4 of the receiving tool 2.
has.

That is, by making the spring portion 7 more elastic, the pressing force against the seat 5 can be increased.

After driving the pressing tool, to prevent it from loosening,
It is good to have irregularities on one or both surfaces that are in contact with the receiver and the pressing tool.

A bolt holder 8 is provided on the lower surface of the receiver 2 and engages with a head fixing nut 10 of a height adjusting member 9 for adjusting the height of the receiver 2.

The height adjusting member 9 includes a bolt 11 having a fixing nut 10 on its head, a pipe band 14 with a bolt receiving nut 12, and an unevenness adjusting nut 13 fixed to the bolt 11.

The height of the support 2 can be adjusted by the height adjustment member 9 by rotating the unevenness adjustment nut 13.

That is, houses that are 4 to 5 years old generally have unevenness in the ridge materials, main building materials, etc. due to ground subsidence, and if the construction is continued as is, the film will wrinkle, causing aesthetic problems. Therefore,
In the present invention, in order to adjust the unevenness of the aggregate of the existing house, a height adjustment member 9 that can be adjusted up and down is attached to the mounting bolts of the holding material and the house aggregate (pipe or shaped steel), so that the level can be adjusted. .

FIG. 2 is an external view of the greenhouse house, and the seat anchoring device of the present invention is attached to the part A or B in the figure.

FIG. 3 is a perspective view showing an embodiment of the receiver according to the present invention.

FIG. 4 is a perspective view showing an embodiment of a pressing tool according to the present invention.

FIG. 5 is a schematic diagram showing the engagement relationship between the pipe band and the height adjustment member.

As mentioned above, the present invention relates to a fastening device for attaching a hard film or other sheet-like material that is attached under tension to the roof or side of a house.
The adhesive force (shear stress) with double-sided adhesive tape or adhesive replaces the conventionally common tightening with screws.
Then, by applying the stiffness (Young's modulus) of the hard film and folding it in a 180° direction, it is possible to provide a strong locking device that can withstand almost the breaking strength of the film by utilizing the frictional force.

When setting the greenhouse covering material (sheet-like material) on the roof and sides using the tensile strength of the film, a tightening jig (bolts, turnbuckles, etc.) is required.
It is necessary to tension the film tightly and prevent it from flapping or tilting due to the wind, and it is possible to provide a locking tool that can hold the film close to its tensile strength (25 kg/mm ² ).

With conventional screw retainers, the stress is not evenly distributed to each screw, and if a strong force is applied, the film may shift, the screw hole may enlarge, and there is a risk of rain leakage or, in extreme cases, breakage. However, in this invention, the work of driving screws with an electric drill at the top of the roof ridge (20cm pitch in the depth direction of the house) has been improved.
2 rows on the side of the house) is eliminated, and the work is as simple as driving the pressing tool in with a hammer or the like, making it possible to provide a locking tool that is effective in reducing costs and speeding up execution.

[Effects of the invention] With the above configuration, the invention has the following features.

In other words, the biggest drawback of a house that utilizes the tensile strength of a hard film is that if the film end face is not strong enough to hold, it may break from the holding part due to suction or wind pressure from strong winds, and the workability of screwing is poor. However, according to the present invention, (a) The holding strength is strong, and it is possible to hold a sheet-like object close to its absolute strength.

There are no screw holes in the film and the long sides can be held continuously, so there is no chance of rainwater seeping in.

c) The construction speed is significantly increased compared to the screw driving method. Furthermore, the execution accuracy is improved and wrinkles near the locking tool are eliminated.

D. Curling in the existing house can be corrected by adjusting the locking tool up and down, and the film can be stretched uniformly without wrinkles.

It is possible to significantly reduce the cost of film expansion.
