2. Description of the Related Art Conventionally, when a synthetic resin foam such as a rigid polyurethane foam is used as a heat insulating material on a building outer wall or a roof at a construction work site, a stock solution is poured between columns, studs, rims, rafters, and the like. Although spray coating was used, this spray method had a problem that the stock solution of the heat insulating material was scattered around and the work could not be performed unless the entire building was covered.

Accordingly, the present inventor has previously proposed "a method of injecting a heat insulating material into a building". According to the method, `` The method of injecting a heat insulating material in the building of the present invention is to fix a holding plate support having a through hole for a fixture having a plurality of rising pieces inside the periphery of the opening of the heat insulating material injection space, After the holding plate is removably fixed to the opening by the engagement between the locking projection of the fixing member and the rising piece in the fixing plate insertion hole of the holding plate support, heat is insulated in the heat insulating material injection space where the holding plate is fixed. In addition, it is characterized in that the material is injected. ”Further,“ the presser plate support having the locking pieces is fixed inside the periphery of the opening of the heat insulating material injection space, and then the hook provided on the presser plate is attached to the presser plate. After the holding plate is detachably fixed to the opening by being locked to the locking piece of the support, the heat insulating material can be injected into the heat insulating material injection space to which the holding plate is fixed. " Pertaining to the injection method.

[0004]

According to the above-mentioned injection method, although the stock solution of the heat insulating material is not scattered, the holding plate can be easily attached and detached, and the operation can be carried out while checking the injection condition, but the positioning of the support is performed. However, there is a problem that the installation takes time and effort.

The pressing plate 21 is made of a transparent plate such as polyvinyl chloride, and is 5-20 mm × 450 m in view of workability.
A size of about mx 2000 mm is desirable. Reference numeral 22 denotes a sheet, which is a polyethylene sheet having a thickness of 0.2 mm or more in this embodiment, and is laminated on the holding plate 21. Instead of a polyethylene sheet, a sheet or release agent of a material having a good release property with respect to the heat insulating material 31 injected can be used.
As shown in FIGS. 7 and 8, the sheet 22 has a width equal to or larger than the interval between the vertical guides 13 attached to the surface of the holding plate 21 where the heat insulating material is installed, and the holding plate 21.
The length of the holding plate 21 is equal to or longer than that of the holding plate 21, that is, the area is larger than the outer periphery of the holding plate 21. Both the holding plate 21 and the sheet 22 are bonded with a double-sided tape or the like. If both the holding plate 21 and the sheet 22 are transparent, the inside can be seen through.

It is preferable that the reinforcing bar 23a provided at the lower end of the wing is provided so as to abut on the lateral guide 14. In this case, the reinforcing bar 23b at the upper end is positioned and fixed so that the reinforcing bar 23a at the lower end is brought into contact with the lateral guide 14 and the holding plate 21 can be installed. When the reinforcing bar 23a at the lower end is brought into contact with the lateral guide 14 and the holding plate 21 is installed, the injection port 25 is at a fixed position, and stable work can be performed.

FIG. 9 shows a pressing plate 21 used in another embodiment of the present invention. In this embodiment, two holding plates 21 are connected by a connecting bar 26 so that the vertical guides 13 can be installed at two intervals at a time.

In order to install the heat insulating material at the place where the heat insulating material is to be installed, first, the upper and lower ends of the holding plate 21 are inserted under the horizontal guide 14. Then, an unfoamed hard polyurethane foam solution, which is a heat insulating material 31, is injected from the inlet 25 between the surface 12 on which the heat insulating material is to be installed and the sheet 22 on the lower surface of the holding plate to foam the heat insulating material. The heat insulating stock solution may be liquid or foamy, and the injection amount is the amount of the foamed rigid polyurethane foam covered with the pressing plate 21 or the sheet 22, and as shown in FIG. If the lower end of the holding plate 21 is moved so as to cover a part of the previously injected heat insulating material 31 when it is moved to the heat insulating material installation position, unfilling can be prevented, and work with a constant amount can be prevented. Becomes possible. That is, in this embodiment, the height is 500 mm.

The movement is restricted by being supported by the lateral guide 14,
Better prevent. Instead of the rigid polyurethane foam, any material can be injected as long as it has a heat insulating effect or an airtight effect and a liquid or foamy stock solution foams. For example, urethane-modified polyisocyanurate foam, polyisocyanurate foam, phenol foam and the like can be used.

After the foaming of the stock solution of the heat insulating material, the holding plate 21 and the sheet 22 are moved to the position where the heat insulating material is not installed as shown in FIG. 6, and the end of the pressing plate 21 is inserted under the horizontal guide 14 at the place. Next, a heat insulating material stock solution is injected and foamed. Thereafter, the operation is repeated sequentially to install the heat insulating material 31 at the heat insulating material installation location.

If a sheet 22 having a width and length wider than the interval between the vertical guides 13 attached to the side is provided, the sheet 2
2 is deformed and adapted to prevent leakage of the heat insulating material even if there is a gap of 15 mm or less between the holding plate 21 and the vertical guide 13. Therefore, even if there is an inevitable variation in the interval when the vertical guide 13 is installed, no problem occurs in the installation of the heat insulating material.

After injecting the undiluted solution of the rigid polyurethane foam as the heat insulating material 31, it is monitored through the press plate 21 and the sheet 22 until the foaming is completed. After moving to the installation position, the rigid polyurethane foam stock solution is again injected and foamed. The heat insulating material 31 is installed from the lower side to the upper side of the ventilation barrel edge 13 by repeating the operation sequentially.

After the heat insulating material is installed, the horizontal guide 14 is preferably removed, and a roof material, for example, for a roof, or an exterior material or interior material for a wall is provided between the surfaces of the vertical guide 13. Then, a space is created between the roofing material, the exterior material, and the like and the heat insulating material, and the roof or the wall is provided with a heat insulating effect and air permeability.
