Description

The present invention relates to a heat insulating structure of a building and a method of constructing a building and a heat insulating material.

Conventionally, as described in Patent Document 1, it is known to install a heat insulating material inside a wall of a building in order to increase the heat insulating property of a building such as a house. As the heat insulating material, a foamed heat insulating material such as polystyrene or a fiber-based heat insulating material is used, and there is also a heat insulating material such as polyurethane foam that is sprayed and used at a construction site.

Patent Document 1 describes a method of constructing a heat insulating material using a foamed plastic such as polyurethane foam (urethane foam). In this construction method, first, a plate-shaped honeycomb core is arranged at a construction target location in the wall frame of the building. Next, a precursor of foamed plastic is sprayed onto the honeycomb core, and the precursor foams to generate a heat insulating material (foamed plastic). At this time, the honeycomb core is embedded as a core material in the foamed plastic.

JP-A-2019-73890

In Patent Document 1, when a precursor of foamed plastic is sprayed into a wall frame to foam it, a heat insulating material adheres over a wide range of structural members such as columns and beams. As a result, the rigidity of the structural member increases and it becomes difficult to deform, so that there is a problem that the seismic performance of the building is lowered.

The present invention has been made in view of the above problems, and one object of the present invention is a heat insulating structure of a building capable of improving the heat insulating performance while suppressing a decrease in seismic performance, and a building provided with the heat insulating structure.

In the heat insulating structure of the building, a heat insulating material is provided at the opening of the frame body, and the heat insulating material is adhered to a part of the inner surface of the frame body. Since the airtightness between the frame and the heat insulating material is ensured in this adhesive portion, the heat insulating performance of the building can be improved. Moreover, in this heat insulating structure, an intervening portion is provided in the remaining portion of the inner surface of the frame body, and the heat insulating material is not adhered to the intervening portion. For this reason, it is possible to suppress the deformation of the frame body from being hindered by the heat insulating material as compared with the case where the heat insulating material adheres to the entire inner surface of the frame body without providing the intervening portion, so that the building is earthquake resistant. It is possible to suppress the deterioration of performance. As described above, according to the heat insulating structure of the building, it is possible to improve the heat insulating performance of the building while suppressing the deterioration of the seismic performance.

In the heat insulating structure of the building, the intervening portion may be a tape attached to the remaining portion of the inner surface.

According to this configuration, it is possible to simplify the construction of providing the intervening portion on the inner surface of the frame body.

In the heat insulating structure of the building, at least the surface of the tape facing the heat insulating material side of the intervening portion may be a surface that has been subjected to a mold release treatment so as to be slidable with respect to the heat insulating material.

According to this configuration, the relative movement of the frame with respect to the heat insulating material can be allowed, so that the seismic performance of the building can be further improved.

A building according to another aspect of the present invention is provided with a heat insulating structure of the above-mentioned building. Therefore, according to the above-mentioned building, it is possible to improve the heat insulating performance while suppressing the deterioration of the seismic performance.

The method of constructing the heat insulating material according to still another aspect of the present invention is a method of constructing the heat insulating material at the opening of the frame in the building. In this method, an intervening portion to which the heat insulating material is not adhered is provided on a part of the inner surface of the frame body that defines the opening, and the intervening portion is provided on a part of the inner surface. The opening is filled with the heat insulating material that can be adhered to the inner surface.

According to this method, a part of the inner surface of the frame is cut off from the heat insulating material by filling the opening of the frame with a heat insulating material in a state where an intervening portion is provided. Can be done. For this reason, it is possible to allow deformation of the frame while ensuring airtightness at the adhesive portion between the inner surface of the frame and the heat insulating material, so that it is possible to improve the heat insulating performance while suppressing deterioration of seismic performance.

In the method of constructing the heat insulating material, the intervening portion may be provided on the inner surface of the inner surface outside the center of the building in the inner and outer directions. The heat insulating material may be adhered to a portion of the inner surface inside the center in the inner / outer direction.

In this way, when the frame side is viewed from the inside of the building after the construction of the heat insulating material, it is possible to make it difficult to see the gap that may occur between the heat insulating material and the intervening portion.

In the method of constructing the heat insulating material, the tape which is the intervening portion may be attached to a part of the inner surface.

In this way, it is possible to easily provide the intervening portion with respect to the inner surface of the frame body.
