Then, the holding material 10 is mounted on the back surface side of the elastic adhesive injection hole 24 of the stud material 4. The holding material 10 has a rectangular parallelepiped shape and is made of a sponge-like synthetic resin elastic material such as a sponge material. The holding material 10 is attached in a form sandwiched between the flange portions 21 on the back surface of the stud material 4. The holding material 10 is attached to the upper and lower portions of the injection hole 24 of the stud material 4, holds the elastic adhesive 6 injected from the injection hole 24 so as not to sag, and is fixed between the stud material 4 and the wall surface. It is attached in a state in which a space with a constant vertical cross section is secured around the injection hole 24 so that the amount is filled.
[0019]
There are other forms of the holding material 10 in which a hollow portion extending from the injection hole 24 to the wall surface 2 is provided, but the main point is that the injection material is injected from the injection hole 24 between the stud material 4 and the wall surface 2. It is preferable if the elastic adhesive is held and a constant amount is filled between the stud material 4 and the wall surface 2 to form a connection body having a constant cross section made of the elastic adhesive 6.
[0020]
The elastic adhesive 6 is injected and filled between the wall surface 2 and the stud material 4 and between the upper and lower holding materials 10. As the elastic adhesive 6, an adhesive made of a resin system having elasticity after curing is used, but preferably a modified silicone that is solvent-free and excellent in durability and adhesiveness without the need for primer treatment. Resin adhesive is good.
[0021]
The foamed urethane agent 8 is an adhesive made of a foamable urethane resin liquid (foamed urethane foam), which cures from the surface and becomes sufficiently hard to stretch the interior material in a few minutes to a few hours. Used. Here, paying attention to the quick curing time of the urethane foam 8, the urethane foam 8 is filled between the wall surface 2 and the stud material 4 and used as a temporary fixing of the stud material 4 to speed up the construction. In order to improve the workability.
[0022]
In the mounting method, first, as shown in FIG. 2, the runner material 3 is disposed in the vicinity of the corners of the ceiling surface 12 and the floor slab 13 and fixed using anchor bolts 32 or the like. Between these upper and lower runner materials 3, stud materials 4 are installed in parallel with each other at a constant interval. These stud materials 4 are attached by inserting each end portion into a groove portion of the runner material 3. Then, the holding material 10 is mounted between the back surface of the elastic adhesive injection hole 24 of the stud material 4 and the wall surface 2 and on both the upper and lower sides of the injection hole 24.
[0023]
The holding member 10 is attached by being sandwiched by a flange portion 21 bent inwardly in the shape of the cross section C of the stud member 4. The holding material 10 has a role of preventing the elastic adhesive 6 from sagging, and by arranging a pair of the adhesive members at a predetermined interval (space portion), the adhesive material 6 filled in the space portion is disconnected. The area is constant, the connection strength of the stud material 4 to the wall surface 2 is constant, and the construction quality is made uniform. Note that the holding material 10 may be attached to the stud material 4 in advance, and the stud material 4 may be attached between the runner materials 3.
[0024]
Next, the level of the stud material 4 is adjusted by using the adjuster pin 50, the adjusting bar 48 and the like to prevent stagnation. In the same manner as described in the above prior art, the adjustment bar 48 is disposed side by side as shown in FIG. The stud material 4 is arranged so as to maintain a constant distance from the wall surface 2.

When the entire arrangement of the stud material 4 is completed, as shown in FIG. 3, the elastic adhesive 6 is injected from the elastic adhesive injection hole 24 of each stud material 4 using the injection device 34, and the urethane foam agent is injected. The foamed urethane agent 8 is injected from the hole 26. FIG. 4 shows a filling state of the elastic adhesive 6 and the urethane foam 8. This urethane foam 8 is usually cured in about 90 minutes, while it takes 1-3 days for the elastic adhesive 6 to cure.
[0026]
After the injection operation, the urethane foam 8 is cured from the surface. Here, the elastic adhesive 6 and the urethane foam 8 protruding from the surface of the stud material 4 and exuding are removed with a spatula or the like. Then, when the foamed urethane agent 8 has reached the hardness to which the interior material 30 can be attached (about 90 minutes after the injection), the pin 50 and the adjusting rod 48 are removed, and thereafter, the cured foamed urethane agent 8 is removed. Thus, the stud material 4 is held and fixed (temporarily fixed). Thereafter, with the elastic adhesive 6 remaining in an uncured state, the interior material 30 for interior finishing made of gypsum board or the like is stretched on the surface of the stud material 4 temporarily fixed to the wall surface 2 to complete the construction. .
[0027]
5A and 5B show the arrangement of the injection holes 24 of the elastic adhesive 6 and the injection holes 26 of the foamed urethane agent 8 of various stud materials 4 due to the difference in the bonding interval of the adhesive and the like.
