BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a joint material used for forming joints of a heat insulating panel (hereinafter referred to as "outer heat insulating panel") used in a so-called outer heat insulating construction method in which a heat insulating material is arranged on the outside of a building wall surface. The present invention relates to a method of connecting external insulation panels used.

[0002]

2. Description of the Related Art Construction of a concrete wall of a building by a conventional outer insulation method has been performed as follows (see FIG. 4). First, a reinforcing bar (not shown) is assembled at a center position of the wall, and a frame b such as a veneer plate is attached to the indoor side by a supporting member a so as to sandwich the reinforcing bar, and a separator (not shown) is installed on the outdoor side. The outer heat insulation panel c was attached at a constant interval by (1) and was fixed by the fixing member d to form the space e in which reinforcing bars (not shown) were arranged. Next, after pouring concrete liquid f into this space e and curing it, form b and fixing member d
The outer insulation wall was constructed by removing. The outer heat insulating panel c used here is composed of a heat insulating material g made of styrene foam or the like and having a predetermined thickness, and an exterior material h made of a non-combustible siding cement-based board or the like attached to one surface side thereof. .

By the way, the outer insulation panel c is attached to the wall surface.
For attachment, a plurality of outer insulation panels c having a predetermined standard shape are joined.
This is done by connecting each outer insulation panel e to each other.
Joints are formed at the joints. Shape of joint that requires conventional method
The outer insulation panel e on one side₁End face i of heat insulating material g
In addition, is it a heat insulating material such as vinyl chloride foamed rock cell board?
A long prismatic joint material j consisting of
Outside insulation panel e on the other side ₂By abutting the end faces of
It was done by Then, the external cutoff near the joint material j
The sealing material 1 is filled between the heat panel e and the exterior material h.
By doing so, the outer insulation panels e are joined to each other to form joints.
It was formed (see FIG. 5 (A)).

[0004]

[Problems to be Solved by the Invention] However, the above-mentioned construction method
Had various problems. That is, the joint material j is
Outside heat insulation panel e₁Attached only to the other side
Outer insulation panel e₂Is only abutting, so the front-back direction
Displacement occurs in (inside and outside directions) mutual heat insulation panel e ₁e₂
In some cases, they were not flush with each other (see FIG. 5 (B)).

Further, the joint material j is pushed out by the pressure of the concrete liquid f injected to the back side,
As it is, there is a disadvantage that the sealing material 1 cannot be filled. In such a case, since the concrete f is protruding from the joint, the joint material j cannot be pushed into the inside and there is no choice but to take it out. When the sealing material f is filled as it is, it adheres not only to the outer heat insulating panels e on both sides but also to the concrete f to form a three-sided adhesive, which makes it difficult to perform accurate sealing. Therefore, it was necessary to first insert a backup material (not shown) in the trace of the joint material j that was taken out, and then perform the sealing process. In such a case, since the sealing material f and the backup material are not bonded to each other, the two surfaces are bonded and the original sealing function is exhibited, but the work efficiency is deteriorated due to complicated work. In addition, since there is no heat insulating material in this portion, there is a problem that the heat insulating effect cannot be expected.

Therefore, the present invention has been made in view of such a problem, and its purpose is to form strip-shaped flanges projecting on both sides of a joint material, and to form the flanges of both blades on the end surface of the outer heat insulation panel. By inserting it into the groove formed in the
A joint material for an outer heat insulating panel pursuing the workability of forming a joint and a method of connecting the outer heat insulating panels using the joint material.
