Description

[Detailed Description of the Invention] This invention relates to bundling and locking and fixing of intersections of timbers used to surround the construction structure during the construction of wooden or concrete buildings.

Conventionally, various binding fittings have been required to bind and lock the intersections of end pieces, and accessories such as clamps, clips, washers, etc. have been used.

However, all of these methods not only require time and skill to install and remove on-site, but also involve the hassle of transporting the binding fittings separately, and the installation process requires time and skill. In this situation, there is a drawback that it is difficult to securely and easily lock and fix the end pieces to each other at predetermined positions.

Particularly in recent years, with the development of a wide variety of modern designs for structures, there has been a demand for methods of using thick timber used in the construction process that can be applied to any type of construction.

SUMMARY OF THE INVENTION Therefore, the present invention aims to eliminate the above-mentioned drawbacks, and to provide a cut material having a high binding strength at the intersection of the cut material and a function of increasing the number of repeated uses.

Below, the present invention will be explained based on the drawings.
As shown in FIGS. 1 and 2, a stud-shaped fitting protrusion 6 consisting of a head 4 having a semicircular arc-shaped cross section 3 and a leg 5 of the head 4 is attached to the peripheral wall surface 2 of the thick end material 1. , furthermore, the protrusions 6, 6 are provided on the peripheral wall surface 2 at positions facing each other.
A pair of protrusions 6', 6' are arranged at right angles on the lower part of the leg part 5, respectively.
It is firmly welded by welding 7.

A semicircular arc-shaped portion 3 forming the head 4 of the protrusion 6
The peripheral edge 8 is chamfered to form a small circular arc shape 9.

In addition, the length L of the leg portion 5 is at least about 5 mm, so as to correspond to the diameter of a commonly used thick piece of wood.
The height H is desirably about 1 mm, and the thickness T of the leg portion 5 is about 6 mm, considering the outer fitting member described later. However, it goes without saying that these numerical values should be selected appropriately depending on the purpose of use and the base member, and should not be limited in any way.

Next, scaffolding materials, etc. are placed on one of the thick pieces 1', which is tied and fixed by crossing the stud-like fitting protrusions 6 formed on the thick pieces 1 configured in this way. As shown in Figs. 3 to 6, the end piece 1' has beak-shaped vertical cracks formed at both ends 10 of the end member 1'. A fitting member 11 is attached, and the member 11 is attached to the head 12.
are welded and fixed by forming vertical cracks symmetrically on both ends 10 of the end piece 1' to form a beak shape 13, and the width 15 of the beak-shaped longitudinal cracks 14 is as follows. ,
The protruding body 6 attached to one of the above-mentioned end pieces 1
The beak-shaped sliding surface 16 is fitted over the leg portion 5 of the protrusion 6 of the thick end material 1 and slides thereon.

The sliding contact surface 16 has a bulge 1 in the middle of the drum surface.
7 and a beak-shaped outer fitting member 11
Due to its own elasticity, the external fitting member 11 is prevented from being pulled out from the projection 6 due to external force such as vibration. The length of the beak-like member 13 of the outer fitting member 11 is preferably about 2 to 3 times the diameter of the end piece 1'.

Then, an external fitting member 11 fitted to the protrusion 6
The beak-shaped member 13 and the thick end material 1' have a welded portion 17 formed with a pair of left and right vertical cracks 14, that is, the inner circumferential wall surface 18 of the thick end material 1 is abutted and locked.

Next, the two end pieces 1 configured in this way,
In order to assemble 1' on site, one of the end pieces 1' is first fitted to the vertical support of the end piece 1 that has been erected correctly. Slide the beak 13 of the end thick material 1', which is one of the horizontal members, onto the fitting protrusion 6 of the material 1, which is shaped like a rivet in the crevice 14, from above to below. It fits by pressing and tapping lightly.

At this time, as mentioned above, depending on the external form of the building, the surrounding form of the thick timbers is required in various directions, but in the case of the present invention, the fitting protrusions are installed by changing the phase. Therefore, in any direction,
Since it has the functionality of being able to cross-bind pieces of wood, it not only allows for a wide range of uses, but also has very little damage during transport, unlike conventional products, and is not bulky. The portions are also small.

Moreover, it is easy to install and remove, and has excellent workability.

Furthermore, as shown in FIGS. 7 and 8 as other embodiments, the present invention further includes bundling at the intersection of thick timbers,
This has the great advantage of improving the practicality of locking and fixing.
