Description

[Detailed description of the invention] This invention relates to a pipe attachment device to steel materials, and is mainly used in multi-building type agricultural vinyl greenhouses.
When placed between each vinyl house building, for example, a steel material with a groove-shaped cross section, which becomes a gutter, is connected and fixed with a pipe material of a predetermined diameter, such as a beam, in an upright manner. This invention relates to an apparatus for attaching pipes to steel materials, which enables simple and quick connection work in a one-touch manner without requiring any secondary processing.

Conventionally, in agricultural vinyl greenhouses, in order to attach beams and other pipe materials to the connecting steel sections arranged between each building, for example, pipe materials were formed at the lower end of the upper end of the groove-shaped steel side wall. A pair of steel members are joined at the crushed part and fixed with screws, or the outer surfaces of each other's deep parts are joined back to back, and the lower end of the pipe material is inserted into the side wall of the steel material,
I'm trying to weld it in place. Therefore, the former requires tedious work such as crushing the pipe material and drilling screw holes, and the latter requires tedious work such as drilling penetration holes in steel materials and welding. However, it was extremely troublesome and I could not expect the work to be completed quickly.

Therefore, this idea was devised to solve the above-mentioned conventional drawbacks, and it is possible to perform one-touch, simple and quick connection work without requiring secondary processing on either steel or pipe materials. As a result, we succeeded in connecting and fixing the two, and this invention will be explained below with reference to the drawings.

That is, one example is a lip channel steel material S
A lower piece 5 facing the upper piece 2 is bent and connected to the lower end of a side wall 4 extending vertically from the outer edge of the upper piece 2 located on the outside. is an engagement piece 7 that engages with a lip L of a channel steel material S, and a side wall W.
A presser piece 8 whose tip edge abuts the inner surface is bent and connected, and an insertion opening 3 is opened in the upper piece part 2 into which a pipe material P to be orthogonally connected to the channel steel material S in an upright manner is inserted. The lower piece portion 5 to which the lower end of the pipe material P comes into contact
, a support body 1 consisting of a fitting positioning piece 6 that is fitted into the pipe material P and an arcuate inner bottom piece 11 that comes into contact with the outer peripheral surface of the pipe material P are provided on both sides from one end to the other end. The wedge body 10 has a generally groove-shaped cross section and is forcibly inserted into the insertion opening 3 together with the pipe material P.

Thus, the support 1 is obtained by cutting and bending a suitably thick sheet plate, and has a substantially square-shaped side surface as shown in the figure.

The upper piece 2 of the support body 1 is formed wider than the diameter of the pipe material P, and has an insertion opening 3 opened in the upper piece 2.
In consideration of supporting and fixing the pipe material P without rattling when the wedge body 10 is forcibly inserted, it is provided with a U-shaped inner edge on which the wedge body 10 tightly slides, and therefore, For example, it is formed into a square planar shape.

Further, an engaging piece 7 and a holding piece 8 are bent and connected from the inner edge of the upper piece 2, that is, the side edge located on the inner side of the channel steel material S when it is attached to the channel steel material S. In each case, support body 1 made from channel steel material S
This prevents it from coming off and at the same time improves the stability of its attached state. In the illustration, since the engaging pieces 7 may be smaller than the holding pieces 8, the former 7 are arranged on both sides of the latter 8 in a total of one pair, and are provided from both upper side edges of the holding pieces 8. The engaging piece 7 is formed by folding the rectangular portion defined by the L-shaped cut line toward the upper piece 2. At this time, the front shape of the holding piece 8 has a substantially convex outline, and in order to smoothly separate the engaging piece 7 and the holding piece 8, it is extremely effective to provide the circular cutout 7A and the rectangular cutout 7B. (See Figure 4).
By forming the engaging pieces 7 and the presser pieces 8 in this way, the engaging pieces 7 are arranged on both sides of the support 1, and the tip edge of the presser piece 8 can be lengthened, resulting in extremely high connection stability. It will be excellent.

Note that the engagement piece 7 is not limited to the illustrated example, and the engagement piece 7 may be arranged at the center of the holding piece 8, and in any case, appropriate design changes are possible.

The insertion positioning piece 6 provided on the lower piece 5 has a width smaller than the inner diameter of the pipe material P.
Desirably, when inserted into the pipe material P, both edges thereof are brought into contact with the inner circumferential surface of the pipe material P, thereby further improving the connection stability of the pipe material P in an upright state. be able to.

On the other hand, the wedge body 10, like the support body 1, is obtained by cutting and bending a suitably thick sheet material, and the width of the deep bottom piece 11 is not larger than the width of the insertion opening 3. In addition, the tapered wall portion 12 has a narrow portion that is smaller than the difference between the length of the insertion hole 3 and the diameter of the pipe material P, and a wide portion that is larger than the difference between the length of the insertion hole 3 and the diameter of the pipe material P. be.

This invention is constructed as described above, and when used, as shown in Fig. As shown in FIGS. 3 and 4, on both sides of the shaped steel material S, the engaging pieces 7 of the support body 1 are engaged with the lips L, and the tip edge of the holding piece 8 is brought into contact with the inner surface of the side wall W. Then, the lower end of the pipe material P, such as a beam, is inserted into the insertion opening 3 of the upper piece 2, and the fitting positioning piece 6 raised on the lower piece 5 is inserted into the pipe material. After that, the wedge body 10 is brought into contact with the inner surface of the lower piece part 5 so as to be inserted into the inside of the tapered wall part 12. The material P is forcibly inserted into the insertion port 3 while being in sliding contact with the outer circumferential surface of the material P.

Therefore, the support body 1 can be attached to the channel steel S without performing any secondary processing on the channel steel material S, and the wedge body can be inserted into the insertion hole 3 opened in the support body 1. Although the pipe material P is forcibly fitted together with 10, the pipe material P is not subjected to any secondary processing, so the work can be carried out extremely quickly.

The support body 1 also includes an engagement piece 7 that engages with the lip L of the channel steel material S from the inner edge of the upper piece part 2, and a side wall W.
Since the presser piece 8 whose tip edge abuts on the inner surface is bent and connected, when installing it to the channel steel material S,
It can be directly installed in a predetermined position with the entire body tilted from the outside, and once installed, the engaging piece 7 and the holding piece 8 prevent the support 1 itself from separating from the channel steel material S. Moreover, it is stable and does not wobble even under the load of the pipe material P applied on the outside of the channel steel material S.

Since the fitting positioning piece 6 is fitted into the pipe material P which is brought into contact with the lower piece portion 5, it is effective in preventing the pipe material P itself from wobbling, and is not forced into the insertion opening 3. The wedge body 10 is the pipe material P.
By bringing the pipe material P into contact with the outer surface of the side wall W of the channel steel material S, it is further useful for maintaining the connection of the pipe material P in an upright state.

The wedge body 10 has an arcuate inner bottom piece 11 that makes good contact with the outer circumferential surface of the pipe material P, and a tapered wall part 12 that gradually becomes wider from one end to the other end. , the pipe material P is tightened with the forced insertion work, and at this time, it is possible to achieve a tight connection even if there are slight differences in the diameter of the pipe material P and the width of the insertion port 3.

As explained above, according to this invention, for example, pipe materials of a predetermined diameter, such as beams, are connected in an upright manner to lip channel steel materials that are placed between each building of a vinyl house and serve as gutters. It can be fixed easily and quickly with one touch without requiring any secondary processing on either steel or pipe materials, and the tight connection and fixation also prevents separation due to external shocks and vibrations. , there is no fear of slipping out, and it is extremely stable, which provides useful effects in practical terms.
