Description

[Detailed description of the invention] The present invention relates to a joint for crossing and joining the shapes that make up the supports, girders, etc. of agricultural film houses, and allows the tensioning of the film at the intersections of the shapes without any hindrance. In addition, the number of parts is small, the manufacturing is easy, and the materials are economical.

Embodiments of the present invention will be described in detail below with reference to the drawings.

In the embodiment shown in Figs. 1 and 2, A is a shaped material whose upper part is bent into the film mounting frame 1, and which is folded back to the outside of the inwardly directed edges 2, 2 which extend inwardly to hang down. side 3
The lower part of the film mounting frame 1 is curved in a cross-sectional shape 4 so as to face parallel to the lower surface of the film mounting frame 1, and one side 3 that hangs down from the inward edge 2 and the opposite side 5 hang short. , the entire cross section is approximately square.

Reference numeral 6 denotes a zigzag spring for holding the film, which is fitted inside the inward edge 2.

B and B are joint members bent from a single iron plate so as to be plane symmetrical with respect to a vertical virtual plane (not shown).

That is, the upper and lower edges of the two opposing vertical parallel plate parts 7, 7 are bent so as to face each other in the horizontal direction at right angles to the parallel plate part 7, and then the parallel plate parts 7 are bent in parallel with the parallel plate part 7. It is bent toward the center of the portion 7, and then bent back toward the parallel plate portion 7 to form a bent edge 8 with a piece-shaped cross section, and the front edge of each parallel plate portion 7 is bent on both sides. The sleeve plates 9, 9 are bent at right angles to extend integrally, and the shaft parallel plate portions 10, 10 extend rearward from the respective upper and lower edges of both sleeve plates 9, 9.
extends integrally to form a joint member B.

Reference numeral 11 indicates a hole in the sleeve plate 9 through which the bolt 13 passes, and reference numeral 12 indicates a circular hole in the shaft parallel plate portion 10 through which the bolt 14 passes.

15 is a recessed portion for maintaining the rigidity of the right angle gap between the vertical parallel plate portion 7 and the sleeve plate 9.

Similar to B, C is a connecting member bent from a single iron plate, and both beads of the channel portion 16 extend laterally to form a hook-shaped cross section 17.
It shows.

The inner end 18 of the force gear-shaped part 17 is bent upward into the small part, and when it is inserted into the lower hook-shaped bent edge 8 of the joint member B, the hook tip a
abuts the bottom of the

D is a bendable, flat cross-section shaped member having an inward edge 19 and used exclusively for film attachment.

In attaching this film, a zigzag shape similar to that used for profile A is used as a film holder.

Dimensions of joint member B, mold material A, and mold material 1. l' and l'' have the same length.

The above-mentioned joints are used at the crossing points 26 of the film house profiles as shown in FIG. 4, and are joined as shown in FIG. 2.

That is, first, the inward edges 2 of the profile A are fitted inside the hook portions a of the upper hook-shaped bent edges 8 of the two joint members B.

In this way, the vertical parallel plates 7 of the two joint members B come into contact with the plate surfaces of the sides 3 and 5 of the profile A, so that the connecting member C Insert the key-shaped part 17.

The inner end 18 of the hook-shaped portion 17 abuts on the bottom of the hook portion a, and the top surface of the hook-shaped portion 17 abuts on the bottom surface of the L-shaped portion 4 of the profile A.

In this state, the right shaft parallel plate part 10.10 is inserted into the second end of the same mold material A as the mold material A.

Since the circular through hole 20 is provided opposite to the blind hole 11, when the bolt 13 is inserted into it and screwed with the nut 13', the heights of the inward edge 2 and the hook-shaped bent edge 8 are aligned. 2 of the shape member A is fixed to the right side of the joint member B.

Normally, another section A 2 is also fixed to the left sleeve parallel plate portion 10.10.

In this way, the two shapes A and A are joined by the joint member B in a perpendicular relationship.

However, as shown in FIG.
When inserted through and screwed with the nut 14', the 2nd part of the part A and the part 2 of the part A are joined perpendicularly to the part A.

In this joining, the upper surfaces of the inward edges of each of the shapes A, A-2, and D are at the same height.

Here, a synthetic resin film 22 is placed on top of these mold materials. For example, in mold material A, if the zigzag spring 6 is used to push the spring 6 into the inward edge 2 from above the film 22, the sides of the spring 6 will curl inward. The film 22 is fixed by hitting the opposite corner and the center of the spring hitting the bottom surface 23 of the film mounting frame 1.

Of course, if necessary, the film 22 can also be fixed with zigzag springs 6 on the inward edges of the sections A and 2 of the sections A.

The one shown in FIG. 3 is another embodiment, in which the parallel plates 27, 27 of the right sleeve part are placed downward from the shoulder, and the vertical parallel plate parts 28, 28
The lower edge of the connecting member E is bent into an L-shaped portion 4, and the J-shaped portion 25 of the connecting member E, which has both sides curved to have a J-shaped cross section, is engaged with and connected to this L-shaped portion 24.

In this example, the same parts as in the previous embodiment are given the same numbers.

By using the embodiment shown in FIG. 3, it is possible to join the shapes fixed to the sleeve parallel plate 10 and the sleeve parallel plate 27 at an angle of 180° or less.

Note that the parallel plates 27 of the downward-sloping sleeves in FIG. 3 may be provided on both the left and right sides, and instead of connecting the connecting member E and the L-shaped portion 24, the connecting member C and the hook-shaped bent edge shown in FIG. 8 may be used.

Of course, it goes without saying that the configuration of the connecting member E and the L-shaped portion 24 in FIG. 3 can be adopted in FIG. 1 as well.

The present invention is as described above, and the joint members and coupling members are 1
It is easy to manufacture because it can be processed by bending a sheet of steel, and since the joint parts are plane symmetrical, it is inexpensive both in terms of materials and workmanship. It has the advantage that it can be crossed with simple installation and that the film can be fixed even at the crossing point.
