DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a film fixing tool for fixing a transparent film forming a roof surface or a wall surface of a greenhouse house.

(Prior Art) Generally, a greenhouse house in which greenhouses are cultivated has a frame made of steel frames, and film fixing tools are attached to the barrel here at appropriate intervals, and a transparent film is fixed on the film fixing tools.

Conventionally, a vinyl chloride film is often used as a transparent film used in this greenhouse house, and a structure shown in FIG. 6 is used as a structure for fixing the film.

This is a combination of a receiving rail 1 having a U-shaped cross section with a narrow upper side and a meandering presser spring 2, and a film 4 is inserted from an opening 3 of the receiving rail 1 attached to a frame (not shown). The pressing spring 2 is inserted and fixed, and the film 4 is sandwiched and fixed.

However, the vinyl chloride type film 4 which has been widely used in the past is soft and easy to attach, but it is easily deteriorated. When deteriorated, the light-transmitting property is deteriorated, so that the film needs to be replaced with a new film 4 within about two years, which causes an increase in cost each time and a troublesome replacement work.

For this reason, in recent years, instead of the conventional vinyl chloride type film, a fluorine type or polyester type film which has excellent weather resistance and translucency and can be used for 10 years or more has come to be used.

Since this fluorine-based or polyester-based film is thick and semi-rigid or hard and has high elasticity, the presser spring 2 cannot be reliably fixed by the film fixing tool shown in FIG. 5, so the film having the structure shown in FIG. Fixtures are used. This is a receiving rail 1 having a U-shaped cross section with a narrow upper portion, and T-shaped arm portions 6 on both sides of a screw pocket 5 having an intermediate portion to be inserted and fixed in the receiving rail 1.
6 and a screw receiving block 7 provided in a protruding manner.

The screw receiving block 7 is formed wider than the opening 3, and is inserted from the end of the receiving rail 1 inside and slid at predetermined intervals, and the film 4 is placed on the screw receiving block 7. Press the pressing plate 9 with the screw hole 8 open from there, insert the screw 10 there, and let the film 4 penetrate,
The tip side of the screw 10 is screwed and fixed in the screw pocket 5 having a narrowed middle.

However, in this fixing structure, the number of parts is four and the structure is complicated. Moreover, since the screw 10 is penetrated through the film 4, a hole is opened, and there is a risk of breaking through this hole when a large force is applied.

Moreover, since a large number of screws 10 are attached at intervals of 20 to 30 cm, the installation work is troublesome and the construction cost is high.

(Problems to be solved by the invention) As a result of various researches,
(EN) Provided is a film fixing tool which can be easily fixed to a semi-rigid or rigid film without making a hole by a very simple structure, improves durability, and is inexpensive in construction cost.

(Means for Solving the Problems) The present invention is directed to a receiving rail having a U-shaped cross section with a narrow upper portion, and a cross section H inserted into the receiving rail.
Left and right arms are laterally projected on both sides of the lower end of the main body block, and the main body block is plastically deformed so that the lower end of the block and the tip of the arm contact the inner surface of the receiving rail. It is characterized in that it comprises a pressing block for sandwiching the made film.

(Operation) Next, the operation of the present invention will be described. The receiving rails are attached to the frame of the house made of steel frames in a cascading shape at appropriate intervals.

When a film is placed on the receiving rail and then the pressing block is inserted inward from the opening of the receiving rail, the film is pushed.

When the upper part of the main body block having the H-shaped cross section is sandwiched in this state, the upper part of the main body block having the H-shaped cross section becomes narrower and the lower end portion spreads laterally to be plastically deformed.

As a result, the left and right arm portions projecting from the lower end of the main body block also move while rotating outward, and the leading end and the lower end portion contact the inside of the receiving rail via the film, and the film is firmly secured between them. Fixed to.

(Embodiment) An embodiment of the present invention will be described below with reference to FIGS. 1 and 2.

The receiving rail 1 has a U-shaped cross section in which the upper side is narrowed, and a protrusion having a circular cross section along the outside of the opening 3 in the upper side.
11 and 11 are provided, and are entirely made of an extruded material of aluminum and have a width of 30 mm and a height of 10 mm, for example.

Reference numeral 12 denotes a holding block, which is formed with bent portions 14 and 14 outwardly on the upper side of a main body block 13 having an H-shaped cross section, and arm portions 16 and 16 are laterally provided on both sides of lower end portions 15 and 15. The protrusions are provided so as to have a lateral width slightly longer than the opening 3 of the receiving rail 1 and are made of extruded aluminum material having a width of 25 mm and a height of 16 mm, for example.

A method of using the film fixing tool having the above structure will be described. The receiving rails 1 are attached to the frame of a house formed of steel frames in a cascading shape at appropriate intervals.

After that, the receiving rail 1 is covered with the film 4, and then a plurality of pressing blocks 12 are inserted inward from the openings 3 of the receiving rail 1 at intervals along the rail longitudinal direction. In this case, since the lateral width of the presser block 12 is slightly longer than the opening 3, the presser block 12 is tilted, and the film 4 is first pushed in by the tip of one arm part 16 and then the other arm part 16 is inserted. , The film 4 is pushed into the state shown in FIG.

In this state, since the film 4 is semi-rigid or hard fluorine-based or polyester-based, the elasticity is strong and the presser block 12 pops out. Therefore, the main body block 13 having an H-shaped cross-section when the presser block 12 is pressed by hand. When the upper bent portions 14, 14 of the main body block 13 are narrowed by sandwiching them with pliers 17 as shown in FIG.
15 and 15 spread laterally and undergo plastic deformation.

As a result, the left and right arm portions 16 and 16 projecting from the lower end of the main body block 13 also move while rotating outward, and the tip and the lower end portions 15 and 15 come inside the receiving rail 1 via the film 4. Abut.

Therefore, the film 4 is sandwiched between the abutting portions, the pressing block 12 is fixed inside the receiving rail 1, and the film 4 can be firmly fixed.

Therefore, even the highly elastic film 4 can be securely fixed with one touch simply by sandwiching it with the layer 17 and plastically deforming the arms 16, 16 and it is excellent in workability without using screws as in the conventional case.

Further, since the holes through which the screws penetrate are not visible in the film 4 as in the conventional case, it is possible to construct a greenhouse house excellent in strength and durability.

FIG. 3 shows another embodiment of the present invention. Inside the upper opening 3 of the receiving rail 1 having a U-shaped cross section with a narrow upper side, a protrusion 11 having a circular cross section along the longitudinal direction is formed. ,

The presser block 12 is a main body block having an H-shaped cross section.
Bent portions 14, 14 are formed on the upper side of 13, and curved arm portions 16, 16 are laterally projected on both sides of the lower end portions 15, 15, respectively. Shaped protrusion 1
1 and 11 are formed.

In the above structure, first, the film 4 is put on the receiving rail 1, the pressing block 12 is pushed into the receiving rail 1 from above, and the upper bent portions 14 and 14 are sandwiched by the pliers. At the same time that the upper part of the arm becomes narrower, the lower ends 15 and 15 expand and the left and right arm parts 16 and 16 also rotate outward, and the protrusions 11 and 11 at the tips thereof protrude inside the opening 3 of the receiving rail 1. It is possible to securely fix the film 4 which is engaged with the lower side of the portions 11 and 11 and is sandwiched between the portions.

4 and 5 show another embodiment of the present invention, in which the pressing block 12 has an uneven portion 18 formed on the upper outer surface side of the main body block 13 having an H-shaped cross section.

Reference numeral 19 denotes a fixed cap, which is formed in an inverted U-shaped cross section and has tapered portions on the inner left and right wall surfaces which are enlarged toward the opening side.
Twenty, twenty are formed.

The method of using the film fixture having the above structure will be described. When the support rail 1 is covered with the film 4 and then the pressing block 12 is inserted from the opening 3 of the reception rail 1 into the inside, the film 4 is pushed in. The state shown in FIG. 4 is obtained.

After that, when the pressing block 12 is held by hand, the fixing cap 19 is covered from above the main body block 13 having an H-shaped cross section and hit with a hammer to form an H-shaped cross section between the taper portions 20, 20. The upper side of the main body block 13 bites into and is crushed to be narrowed, and the lower end portions 15 and 15 spread laterally to be plastically deformed.

As a result, as shown in FIG. 5, the lower end portions 15 and 15 of the presser block 12 and the arm portions 16 and 16 contact the inside of the receiving rail 1 through the film 4 to fix the film 4. .

In addition, although the case of constructing a greenhouse house has been described in the above embodiment, the present invention can be applied to the construction of a drying room or the like.
