Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a construction for assembling walls, floors, ceilings, roofs, etc., mainly by connecting panels without using frame members, and without using it frequently. The present invention relates to a method of connecting panels and a panel used for the method.

[0002]

2. Description of the Related Art Generally, in a panel construction method (two-by-four construction method), a single-sided panel in which structural plywood is nailed to one surface of a structural material frame that hardly requires on-site processing is used, and a three-dimensional assembly is used to construct a building. Is constructed and structural plywood is nailed to the other side for finishing. In addition, even in a wooden frame building using columns and beams, panels made of such structural materials are often used in order to shorten the construction period by omitting fine frames.

In any case, to assemble the building,
When connecting a panel to another panel or a pillar or a beam, a single-sided panel is used as described above because nailing or bolting is performed from the inside of the structural material exposed at the end surface of the panel. . Then, the heat insulating material is loaded before closing the opening side surface with another structural plywood. However, when adopting other connecting means such as a hosi or shaft assembly, a panel sandwiching a heat insulating material made of a plate material such as urethane foam may be used between the both structural plywoods in addition to the structural material. is there.

[0004]

According to the conventional panel connecting method as described above, the connecting operation is complicated,
Since it is necessary to make work for assembling into the panel, it takes a lot of trouble, especially because it requires finishing as a single-sided panel, so the workability of building assembly is poor and the construction period is shortened. There was a problem.

Further, regarding the structure of the panel, since both structural plywoods are connected by nailing to the structural material, the assembling strength is weak, and especially when an opening such as a window is provided, the structural material is stable as a framework. Remarkably lack sex. In the case of sandwiching a plate material such as urethane foam, although it contributes to the strength to some extent, the bond with the structural plywood is incomplete,
Moreover, since there is a slight gap between the structural material and
Due to the gap, the heat insulation could not be perfected.

In view of the above-mentioned circumstances, the present invention provides a method for easily and firmly connecting a panel to another panel, a pillar, etc., and a panel used for the method which is stable in strength and excellent in heat insulation. Aimed to provide.

[0007]

A method for connecting panels according to the present invention to achieve the above object uses a panel having a connecting groove on its connecting end face, the connecting groove having openings between the structural plywoods on both sides. A connecting member into which the connecting groove fits is fixed to the connecting object, the connecting groove of the panel is inserted into the connecting member, and then the insertion plug is pierced in both structural plywoods and the connecting member sandwiched between them. And

Regarding the fixation of the connecting member to the connecting object, when the connecting object is another panel in the series direction, the connecting member fitted in the connecting groove of both panels is used. Also, in the case of another panel in the right angle direction, a reinforcing member is fitted in the connecting groove of the panel, and the side surface of that portion is bolted, and in the case of a pillar, a base, a beam, or a girder, It is provided with a groove into which the connecting member fits, and bolted there.

The panel of the present invention is provided on the inner surfaces of both structural plywoods.
A webbing for connection, which is arranged between them, is provided with a row of coupling grooves to which the webbing for engagement is hooked, and in addition to the webbing, a plate-shaped heat insulating material made of a plastic foam material is sandwiched between both structural plywoods. Attach the web member and heat insulating material to both structural plywood by pressing and compressing from both sides,
The heat insulating material is characterized in that the web member and the heat insulating material are retracted by being stretched due to the compression so that the connecting groove is opened.

[0010]

Since the panel connecting method is configured as described above, the connecting object is not only the other panel but also the main frame of the building such as the pillar, the beam and the foundation. Even in such a case, the connection of the panels can be completed simply by preliminarily or simultaneously fixing the connection member to the connection target, fitting the connection groove of the panel into the connection member, and inserting the plug into the fitting portion.

Whether the connection object is another panel in series or at right angles, a pillar, a base, a beam, or a girder, each connection means is connected to the connection object by the respective fixing means (claims 2 to 4). The member can be firmly fixed.

Regarding insertion of the insertion plug, the insertion plug hole is opened in advance in the panel, and the insertion plug hole is opened in the fitting state with the connecting member. Alternatively, by simultaneously forming the insertion plug holes in the fitted state with the connection member, the insertion plug holes can be aligned in the panel and the connection member.

Since the panels are constructed as described above, they can be used in the method of connecting the panels described above, and both structural plywoods are joined not only by web members but also by adhesion with a heat insulating material. Strength is strengthened uniformly throughout. Further, since there is no gap between the heat insulating material and the web member, the heat insulating property is also improved.

・ ・ Connected with and. In the periphery, the web member 3 and the heat insulating material 5 are retracted so that the connecting groove 4 is provided over the entire length and width, and the insertion plug holes 9, 9, ... Drilled. Next, the structure of the manufacturing will be specifically described.

In the structural plywoods 1 and 1, the connecting grooves 10 of the web member 3 are vertically arranged in a row so as to be opposed to each other on the inner surface, and are formed in such a width that the ends of the web member 3 are fitted to each other. . As the web member 3, a plywood cut into a strip shape slightly shorter than the structural plywood 1 is used. Further, for the heat insulating material 5, a urethane foam plate material is cut to obtain the web members 3, 3
The width of the web member 3 is the same as that of the web member 3.

An adhesive 8 of vinyl acetate or the like is applied to the inner surfaces of the structural plywoods 1 and 1 and the coupling groove 10, and while the web member 3 is incorporated between the structural plywoods 1 and 1, the heat insulating material 5 is used.
Fit in between. Next, the heat insulating material 5 is compressed by applying pressure from both sides, and the compressed state is maintained. By this compression, not only the adhesion is strengthened, but also the heat insulating material 5 extends laterally and is compressed into the web member 3.

When the pressure is released after the bonding is completed, the assembly as the panel P is completed. In this assembled state, the plug hole 9 is drilled at the factory or on site.

The plug 6 is made of metal or is made of hardwood such as zelkova and has a columnar shape or a tapered trapezoidal pin shape. Further, as the connecting member 2, since the panels P and P are connected in series, a thick plywood cut into a width twice the depth of the connecting groove 4 is used.

Fitting the connecting groove on the panel end face to the connecting member with the base, etc., the connection work can be completed by inserting and inserting plugs, so the connection work is very easy and easy, and the workability of the connection is good, so the construction period of the building Not only is it suitable for shortening, but also because the plug crosses in the direction in which the panel comes out, it has the excellent effect of maintaining a strong connected state in combination with the coupling by fitting with the connecting member. Since there is no advanced processing such as, it is possible to solve the shortage of craftsmen.

Further, even if the object to be connected is another panel in series or at a right angle (claim 2 or 3), the pillar or the base,
Even if it is a beam or a girder (claim 4), the connecting member can be firmly fixed to the object to be connected.

The panel of the present invention can be effectively used in the above-mentioned panel connecting method. Further, not only the two structural plywoods are bonded by the web member but also by bonding with the heat insulating material, so that the bonding strength is uniformly strengthened as a whole. Therefore, it is particularly suitable for building a building of the two-by-four method, and in that case, the strength is maintained even if the window hole is opened. Further, since there is no gap between the heat insulating material and the web member, the heat insulating property is also improved. Further, in manufacturing, there is an excellent effect that it does not require troublesome nailing and is suitable for mass production by mechanization.

Further, in the panel of the present application, since the thick structural plywood on both sides is integrated with the web member, the horizontal cross-sectional area of the member is extremely larger than that of the conventional panel construction method or building construction method, so that a vertical load is applied. Initially, it can be built on a very strong wall body against unexpected external force in the lateral direction, and unlike countless nailed panels like conventional panels, windows and openings etc. can be placed at desired positions on the wall surface. It can be easily cut out and provided.
