Description

[Detailed description of the invention] [Field of industrial application] The present invention is a connecting fitting for square structural aggregates used as pillars and superstructure materials for vinyl houses, etc., and in particular, a connecting fitting for fixing and fixing sheets etc. The present invention relates to a combination connecting fitting suitable for connecting square structural aggregates in a T-shape.

[Prior Art] Conventionally, many connectors for cross-connecting simple house structure aggregates such as cylindrical pipes are known. For example, as a practical fitting for connecting two pipes in a T-shape, the central part of the plate-shaped body is formed into a bent surface that embraces the first pipe, and both ends in the bending direction are respectively It is known that the pipe is formed in a semi-cylindrical shape and can be held so as to wrap around the end of the second pipe from both sides, thereby firmly connecting the first pipe and the abutting second pipe in a T-shape. There is.

However, although it is easier to connect square pipes than round pipes when fixing a relatively wide contact surface, there is no effective way to connect two square pipes in a T-shape without overlapping them. Not very well known.

[Problems to be solved by the invention] In large vinyl houses, square pipes, which have superior structural aggregate strength than round pipes, are used as the main structural material. However, in such a house, there are many connections between square pipes, especially T-shaped joints. Therefore, the present invention has a simple combination structure, is easy to operate, and has a high connection strength using square aggregates. The purpose is to provide connecting fittings.

[Means for Solving the Problems] A holding member that holds the first square aggregate in a hugging manner, and a region in which the vicinity of the tip that is inserted into the gap between the holding member and the first square aggregate is directed toward the tip. A connecting member is formed by integrally forming a wedge-shaped insertion part whose thickness is gradually thinned and a part that embraces the second square aggregate, and the insertion part of the connection member is press-fitted into the gap. By doing so, the first angular aggregate and the second angular aggregate, especially the angular aggregate provided with the receiving groove for fixing the sheet of a vinyl house, etc., can be connected in a T-shape. Hardware provided.

[Embodiments] Hereinafter, embodiments of the present invention will be described in detail with reference to the drawings.

In Figures 1 to 3, reference numbers 1 and 2
is an aggregate used as supports and superstructure materials for vinyl houses, etc. The first square aggregate 1 and the second square aggregate 2 are provided with fixing grooves 3 and 4 along the longitudinal direction for partially fixing cheesecloth, vinyl sheets, or the like. In these fixing grooves 3 and 4, there are two steps 5 and 6 and 7 and 8, respectively.
are formed, and these step portions 5, 6 and 7, 8
The cheesecloth, vinyl sheet, etc. are pressed and fixed by a linear elastic member (not shown).

The connecting fitting for connecting the aggregates 1 and 2 having the above-mentioned configuration is made of, for example, iron and consists of a holding member 10 and a connecting member 11 made of galvanized metal. There is.

The holding member 10 is composed of a flat base 12 and a pair of opposing engaging parts 13 and 14 that stand up on both sides of the base 12 at approximately right angles.
In addition, locking portions 13a, 14a are formed at the tips of each of the engaging portions 13, 14, respectively, in a bent state facing inward, and each of these locking portions 13a, 14a is connected to the first As shown in the drawings and FIG. 2, it is adapted to be able to lock onto the aggregate 1.
The holding member 10 has a base portion 12 and engaging portions 13 and 1.
4 holds the aggregate 1 in a gripped state. Note that each of the engaging portions 13 and 14 of the holding member 10 is
The length is set so that when the aggregate 1 is held as shown in the figure, a slight gap is created between the base 12 of the holding member 10 and the aggregate 1,
In addition, the distance between the engaging portions 13 and 14 is approximately equal to the width of the aggregate 1.

The connecting member 11 has a substantially flat insertion portion 15 that is inserted between the aggregate 1 and the base 12 of the holding member 10.
and an engaging portion 16 formed at a substantially right angle to the rear end of the insertion portion 15. The insertion portion 15 is formed to have a thickness approximately equal to the above-mentioned gap. In addition, near the tip of the insertion portion 15, a thin wall portion 1 that gradually becomes thinner toward the tip is provided.
5a is formed so that it can be easily inserted between the aggregate 1 and the base 12 of the holding member 10. Furthermore, a locking portion 16a is formed at the tip of the engaging portion 16 that engages with the aggregate 2 in an inwardly bent state. prevents it from shifting upward.

[Operation] Next, the connection of the structural aggregates 1 and 2 using the aggregate connecting fittings having the above-mentioned configuration will be explained.

First, one end of the aggregate 1 to be connected is held by the holding member 10.
Insert inside. Then, as shown by the chain line in FIG.
It is placed on the insertion part 15 in a state where it is engaged with the first engaging part 16.

Next, the thin part 15a formed in the insertion part 15 of the connecting member 11 is inserted between the aggregate 1 and the base 1 of the holding member 10.
2, and hammer the connecting member 11 in the direction shown by arrow A using a hammer or the like. By this hammering, the insertion part 15 is placed at a position where the aggregate 2 is held between the engaging parts 13 and 14 of the holding member 10 and the engaging part 16 of the connecting member 11, as shown by the solid line in FIG. It is inserted until the end. As a result, the first aggregate 1 is held more firmly by the holding member 10, and the second aggregate 2 is held by both engaging portions 13 of the holding member 10,
14 and the engaging portion 16 of the connecting member 11, the first aggregate 1 and the second aggregate 2 are firmly connected.

In addition, in the above embodiment, by forming the thin part 15a near the tip of the insertion part 15,
An example is shown in which it is easy to insert between the aggregate 1 and the base 12 of the holding member 10. however,
As shown in FIG. 4, the entire fitting part 15 is formed to be slightly thinner than the above-mentioned gap, and a required number of protrusions 15b are formed near the tip, gradually protruding from the front to the rear. Good too. This protrusion 15a can be easily formed, for example, by press working. In addition, a thin wall portion 1 is provided in the insertion portion 15.
5a, protrusions 15b, etc. between the base 12 of the holding member 10 and the insertion part 115,
Furthermore, it is also possible to adopt a configuration in which other wedges are driven in.

[Effect of the invention] As described above, in the present invention, the holding member 10
While holding the first aggregate 1 in a gripped state,
With the engaging portion 16 of the connecting member 11 engaged with the second aggregate 2, the insertion portion 15 of the connecting member 11 is press-fitted between the holding member 10 and the first aggregate 1. , an engaging portion 1 between the holding member 10 and the connecting member 11
The second aggregate 2 is held between the two aggregates 6 and 6, and the metal fitting of the present invention, which connects both aggregates 1 and 2 to each other in this way, is extremely easy to connect.
Furthermore, there is no problem with the connection strength, making it a practically desirable connection fitting.
