Abstract

(57) [Summary] [Purpose] To improve workability and efficiency in heat insulation work of on-site resin foaming construction. [Structure] A fine net is attached to the net support on the lower side of the roof or on the inside of the outer wall to carry out heat insulation work for on-site resin foaming.

Description

DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a method for insulating a roof or wall of a building.

[0002]

2. Description of the Related Art As shown in FIGS. 4, 5, 6, and 7,
Insulation methods are known in which on-site foam insulation is applied directly to the roof and walls.

[0003]

[Problems to be Solved by the Present Invention] The conventional heat insulating method described above has the following problems.

<A> The heat received by the roof 7 or the outer wall 10 may be directly received by the heat insulating material 8, and the building material outside the heat insulating material 8 may cause a performance failure.

<B> The base wood of the roof 7 or the outer wall 10 is blocked by the heat insulating material 8 and rots.

<C> To solve the above problem, FIG.
As shown in FIG. 7, there is a method of doubling the roof or the wall, but there is a problem of construction cost.

[0007]

[Purpose of the Invention] The present invention has been made in view of the above points, and the purpose thereof is to reduce the labor of the heat insulating surface, reduce the foaming pressure, and insulate the roof or outer wall with excellent workability of foaming heat insulation. To provide a method.

[0008]

[Means for Solving the Problems] When the present invention is to perform on-site resin foaming of a roof or a wall from the inside of a building, a fine net is attached to the inside of the roof or the wall to perform on-site resin foaming on the net. This is a method for insulating the roof or wall, which is characterized in that it is performed.

[0009]

By performing on-site resin foaming of the net, the net and the base material of the net receiver are tightly fixed by the resin penetrating from the net of the resin foam.

[0010]

Embodiment 1 An embodiment of the present invention will be described below with reference to the drawings.

<A> FIG. 1 shows an embodiment in which a net 9 is directly attached to a main building material for receiving the roof material 7 and the heat insulating material 8 is foamed on site.

<B> FIG. 2 shows an embodiment in which a net 9 receiving tarpaulin 5 is provided on a main material 3 for receiving the roofing material 7, and a net 9 is stretched on the tarpaulin to foam the net 9 in situ.

<C> FIG. 3 shows an embodiment in which a net or a girder is provided on the beam or girder, a net 9 is attached to the girder, and the net 9 is foamed in situ.

<D> FIG. 8 shows an embodiment in which the net 9 is directly attached to the pillar 1 or the stud, the outer wall base material 15 is attached and the air layer 12 is provided, and foaming is carried out in situ.

<E> FIG. 9 shows an embodiment in which an outer wall outer base 14 which is difficult to transfer heat is attached to the pillars 1 and the studs, and a net is attached to the base to foam on-site in consideration of heat bridge reduction.

[0016]

According to the present invention, the following effects can be obtained from the above-described features. <B> The net is easy to handle, the workability is improved, and heat insulation can be performed regardless of the shape of the house. <B> Since an air layer can be obtained without using a double structure, construction can be simplified, the construction period can be shortened, materials can be reduced, and labor can be saved. <C> Since the foaming pressure generated when the resin is foamed in situ is dispersed to the outside, foam cracking is less likely to occur. <D> Since the wood is not sealed by the resin, the wood is less likely to rot when exposed to air.
