JPH0657833A - Method for filling heat insulating material to wall - Google Patents

Abstract

PURPOSE:To easily fill a heat insulating material to all the internal corners of a wall, and make a temporary cover reusable. CONSTITUTION:On the back side wall frame 1 of a wall 3 which has a face plate 2 mounted on the surface side of the wall frame 1 and is opened on the back side, a temporary cover 4 is attachably and removably mounted to block the opening. The temporary cover 4 has a fitting hole 6 for fitting the blowing part of a blowing device for heat insulating material filling. The blowing part of the blowing device for heat insulating material filling is fitted to the fitting hole 6 to simultaneously blow a fibrous heat insulating material 16 and a binder. Thereafter, the temporary cover 4 is removed to reuse the same.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method of filling a building wall with a heat insulating material.

[0002]

2. Description of the Related Art In a conventional heat insulating wall, a face plate is attached to the front surface side of a wall frame, and a back opening of a wall whose back is opened is filled with a heat insulating material such as rock wool by hand, and a back surface is formed. A net was attached to the opening side of the so that the heat insulating material would not fall off.

[0003]

However, in the above-mentioned conventional example, since the filling work is a manual work, the work is troublesome and it is not possible to fill every corner, and a net or the like is attached to insulate it. There was a problem that the cost of the net was high because the net was kept as it was so that the material did not fall off.

The present invention has been made in view of the above-mentioned problems of the prior art. The purpose of the present invention is to make it possible to easily fill all the inside of a wall with a heat insulating material, and further It is an object of the present invention to provide a method of refilling a wall with heat insulating material.

[0005]

A method for filling a wall with a heat insulating material according to the present invention is a wall frame on the back side of a wall 3 in which a face plate 2 is attached to a front surface side of a wall frame 1 and a back side is opened. 1, a temporary lid 4 is detachably attached so as to close the opening, and a fitting port 6 for fitting a blowing portion 5 of a blowing device 7 for filling a heat insulating material is provided in the temporary lid 4, and the filling hole 6 is filled with a heat insulating material. The blowing part 5 of the blowing device 7 is fitted to blow the fibrous heat insulating material 16 and the binder at the same time, and then the temporary lid 4 is inserted.
The present invention is characterized in that the problem of the conventional example described above is solved by adopting such a method.

[0006]

According to the present invention having the above-mentioned structure, however, the temporary lid 4 is formed so as to close the opening in the wall frame 1 on the back side of the wall 3.
Is detachably attached, and the temporary lid 4 is provided with a fitting port 6 for fitting the blowing part 5 of the insulating material filling blowing device 7, and the blowing part 5 of the insulating material filling blowing device 7 is fitted into the fitting port 6. Since the fibrous heat insulating material 16 and the binder are blown at the same time, the heat insulating material 16 can be easily and surely filled into every corner of the wall 3 and fixed with the binder filled, and the temporary lid 4 is removed. The temporary lid 4 can be reused.

DESCRIPTION OF THE PREFERRED EMBODIMENTS The present invention will be described in detail below with reference to the embodiments shown in the accompanying drawings. 1, 2 and 3 show an embodiment of the present invention. First, as shown in FIG. 1, first, the face plate 2 is attached to the front surface side of the wall frame 1, and the temporary lid 4 is attached to the wall frame 1 on the back side of the wall 3 having the back opened. Fasteners 8 such as nails
To fix. The temporary lid 4 applies a mold release agent to a mesh body 9 such as a wire mesh, and a peripheral frame 10 is provided on the outer peripheral portion of the mesh body 9, and the peripheral frame 10 is detachably attached by a fastener 8 such as a nail to a wall frame. It is attached to 1. The mesh of the mesh 9 is about 10 mesh. The mesh body 9 is formed with a fitting opening 6 for fitting the blowing portion 5 of the blowing device 7 for filling the heat insulating material. After closing the opening of the wall frame 1 on the back side of the wall 3 with the temporary lid 4 composed of the net body 9 having the above-described structure, as shown in FIG. The blow-in portion 5 is fitted, and the fibrous heat insulating material 16 and the binder are blown at the same time. Here, rock wool is used as the fibrous heat insulating material 16 and phenol resin or the like is used as the binder. The fibrous heat insulating material 16 and the binder are blown at the same time, and after the binder is cured or semi-cured, the fixing tool 9 such as a nail is removed and the temporary lid 4 is removed to reuse the temporary lid 4. . FIG. 3 shows a state in which the temporary lid 4 is removed. When the temporary lid 4 is removed, a release agent is applied to the net 9 so that the net 9 can be easily released and removed even when the binder is cured.

If a nail having a two-tiered head portion 8a as shown in FIG. 4 is used as the fastener 8, the head portion 8a at the rear end can be used to pull it out. You can easily pull it out. Of course, the fixing tool 8 is not limited to this embodiment, and various other fixing tools 8 can be used as long as they are detachable.

[0009]

According to the present invention, as described above, the face plate is attached to the front surface side of the wall frame, and the temporary cover is provided so as to close the opening in the wall frame on the back side of the wall whose back side is opened. Detachably attached,
This temporary lid is provided with a fitting opening for fitting the blowing part of the insulating material filling blowing device, and the fibrous insulating material and the binder are simultaneously blown by fitting the blowing part of the insulating material filling blowing device into this fitting opening, After that, the temporary cover is removed, so that it is possible to fill the insulating material in every corner of the wall and fix it with the binder filled, and it is easier and more reliable to fill the insulating material than the conventional manual work. In addition, since the binder is hardened to maintain the filled state of the heat insulating material, the temporary lid can be removed and the temporary lid can be reused.
