Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of simply connecting two or more rigid plates such as stainless steel plates and aluminum plates, particularly rigid plates for construction.

[0002]

2. Description of the Related Art Conventionally, when connecting two rigid plates, a method is generally used in which holes are drilled in the rigid plates and bolted. However, the bolted connection method is extremely intricate and inefficient in that it requires many bolt holes to be made in the rigid plate, and bolts must be passed through each of the many bolt holes and then fixed with nuts. It was Also, when dismantling the connected rigid plates, many bolts had to be removed, which was very troublesome.

Welded connections are also used when the rigid plate is a metal plate. For example, when a decorative panel for construction is attached between pillars or the like, a plurality of stainless steel plates or the like are welded into a prismatic shape and fixed to the outside of the pillar, and the end portion of the decorative panel is fixed to this without gaps. In addition to the method of forming a wooden frame, a steel plate is welded into a columnar shape or a prismatic shape to be used as a form of a concrete pillar.

However, in the connection method by welding,
When disassembling the connected rigid plates, there is no other method than cutting with a burner or the like, and thus it was difficult to reuse the disassembled rigid plates. For this reason, it is troublesome to dismantle and remove the rigid plate when the building is renovated or the formwork is disassembled, and the rigid plates that have been dismantled and removed are reconnected and the same structure is assembled. I couldn't do that.

[0005]

SUMMARY OF THE INVENTION In view of the above conventional circumstances, the present invention can simply connect two rigid plates without using welding or bolting, and can easily disassemble them. Therefore, it is an object of the present invention to provide a method for connecting rigid plates, which allows the structure to be returned to the state before connection, and thus the same rigid plate can be reused to assemble a structure repeatedly.

[0006]

In order to achieve the above-mentioned object, in the method for connecting rigid plates provided by the present invention, 2
A bent portion is provided on at least a part of one side of one rigid plate, and the leading edge of the bent portion is bent at an acute angle to the rigid plate side with respect to the bent portion to form a locking edge portion, while a substantially triangular insertion hole is formed. A rod-shaped sheath member having a substantially arrow-shaped cross section having two parallel end portions protruding from the bottom surface of the sheath portion with a gap communicating with the insertion hole is formed, and the two rigid plates are locked. After arranging the bent parts in contact with each other so that the edges are back to back, the locking edges of the two rigid plates are inserted into the insertion holes of the sheath of the sheath member, and the gaps of the parallel end edges are formed. It is characterized in that the bent portion of two rigid plates is sandwiched between the two.

Further, in the rigid plate connecting method of the present invention, when the two rigid plates are connected by the sheath member, the engaging edge portion of the bent portion of the rigid plate forms a substantially triangular sheath portion of the sheath member. It is characterized in that the rear end of the engaging edge portion comes into contact with the bottom surface of the sheath member at the same time as sliding contact with the inclined surfaces on both sides.

[0008]

BEST MODE FOR CARRYING OUT THE INVENTION A method for connecting rigid plates according to the present invention will be described in detail with reference to FIGS. 1 and 2 showing one specific example thereof. 1A is a perspective view of two rigid plates to be connected, and FIG. 1B is a perspective view of a sheath member. FIG. 2 is a perspective view showing a state in which two rigid plates are connected by using a sheath member.

In the present invention, as shown in FIG. 1 (a), by bending a rigid plate, a bent portion 2 is provided on the entire length of one side of two rigid plates 1 or a part thereof, and the bent portion is further formed. Two
The leading edge of the is bent to the rigid plate 1 side with respect to the bent portion 2 at an acute angle to form the locking edge portion 3. In this specific example, the two rigid plates 1 after processing have exactly the same shape, and the bent portion 2 is formed by bending the rigid plate 1 at about 45 ° with respect to the rigid plate 1.
The locking edge portion 3 is bent at about 45 ° with respect to the bent portion 2.

On the other hand, a sheath member 4 connecting the two rigid plates 1
As shown in FIG. 1B, is composed of a substantially triangular sheath portion 5 and two parallel end portions 6 formed by projecting at a right angle from a bottom surface 5 c of the sheath portion 5. The substantially triangular insertion hole 5a on the inner side communicates with the gap 6a between the two parallel edge portions 6. This sheath member 4 can also be formed by a simple bending process of a rigid plate. In this specific example, the two inclined surfaces 5 of the sheath portion 5 are formed.
The apex angle formed by b is 90 °, and the angle formed by the inclined surface 5b and the bottom surface 5c is about 45 °.

To connect two rigid plates by using the rod-shaped sheath member 4 having a substantially arrow-shaped cross section and having the above-mentioned sheath portion 5, FIG.
As shown in FIG. 1, first, the two rigid plates 1 are arranged such that the bent portions 2 are in contact with each other such that the locking edges 3 are back to back. At this time, if the corners of the bent portions 2 of the two rigid plates 1 are aligned with each other, the tops of both the locking edge portions 3 are aligned with each other. Part 5.
As a result, the engaging edge portion 3 is inserted into the insertion hole 5a of the sheath portion 5, and at the same time, the bent portion 2 is inserted into the gap between the two parallel end edge portions 6.
Is sandwiched between the two rigid plates 1 and can be connected to each other.

In the concrete examples shown in FIGS. 1 and 2, the bent portion 2 of the rigid plate 1 is elongated for the sake of clarity. However, the bent portion 2 is shortened as shown in FIG. It is also possible to connect between 4 and the rigid plate 1 without a gap.

When the rigid plates 1 are connected using the sheath member 4 of the present invention, for example, as shown in FIG.
The locking edge portions 3 of the sliding contact with the inclined surfaces 5b on both sides of the substantially triangular sheath portion 5 of the sheath member 4, and even if the sheath member 4 is pulled in the direction along the bent portion 2 of the rigid plate 1, The locking edge portion 3 of the plate 1 abuts against the bottom surface 5c of the sheath portion 5 and cannot be pulled out, so that the two rigid plate 1 can be reliably connected. Further, the rear edge of the locking edge portion 3 of the rigid plate 1 is the sheath portion 5 of the sheath member 4.
If the length is adjusted so that it contacts the bottom surface 5c of the
At the same time as inserting and connecting, the corners of the bent portions 2 of the two rigid plates 1 can be aligned.

Moreover, the sheath member 4 has two parallel end portions 6, and since the bent portions 2 of the two rigid plates 1 are held by being sandwiched between the parallel end portions 6, the two bent portions are held. The two rigid plates 1 cannot be separated from each other, and the two rigid plates 1 cannot be easily separated. That is, if the parallel edge portions 6 are not provided, when a force that separates the bent portions 2 is applied to the two rigid plates 1, the bent portions 2 and the sheath member 4 are deformed by a slight force.

By using the above-described connecting method of the present invention, it is possible to connect a plurality of rigid plates to form various structures simply by changing the shapes of the rigid plates and the bent portions. For example, as shown in FIGS. 1 to 3, if the angle between the rigid plate 1 and the bent portion 2 is set to 45 °, four rigid plates 1 can form a prism. This method can be used for producing a form of a concrete pillar or a prism such as a stainless steel plate used when a decorative panel for construction is mounted between the pillars.
Similarly, a box such as a tool box (the lid is separately openably connectable) can be formed using the five rigid plates 1, but in this case, the sheath member 4 can be inserted and attached. The bent portion 2 is formed only on a part of one side of a part of the rigid plate 1.

Further, as shown in FIG. 4, if the angle between the rigid plate 1 and the bent portion 2 is 90 °, a plurality of rigid plates 1 can be connected to form a large flat surface, so that a scaffold or a construction site can be constructed. Can be used to build walls of things. Furthermore, as shown in FIG.
It is also possible to construct a cylinder by bending a plurality of rigid plates 1, and such a cylinder is effective as a formwork of a concrete pillar or the like.

The plurality of rigid plates connected by the method of the present invention can be easily disassembled by simply pulling out the sheath member and returned to the original rigid plate before the connection. Therefore, the same rigid plate and sheath member can be reused to repeatedly assemble and disassemble the same structure any number of times.

[0018]

According to the present invention, when two rigid plates are connected, they can be easily and firmly connected without the need for welding or bolting, and they can be easily disassembled before connection. It can be returned to the state of. Therefore, the same rigid plate can be reused and the same structure can be repeatedly assembled many times, which is extremely economical.
