2. Description of the Related Art Concrete structures are widely constructed as buildings, and reinforced concrete structures (RC structures) and steel-framed reinforced concrete structures (SR structures) are used due to their reinforcing structures.
C), reinforced concrete with glass fiber (GRC), precast concrete (PC)
(Fabricated, prefabricated) etc.

On the other hand, there are an outer insulation method and an inner insulation method as a heat insulation method for a building. In such a concrete building, an inner heat insulation method for attaching a heat insulating material to the indoor side has conventionally been generally adopted. Has been done.

In this inner insulation method, a heat insulating material is attached to the inner side of the outer wall, but if there is a partition wall continuous with the outer wall, such as a partition wall for partitioning a room or a ceiling slab for partitioning upper and lower floors. However, the heat insulating material is interrupted at these places, and there is a problem that dew condensation occurs due to loss of heat insulation.

Therefore, recently, as shown in FIG. 4, the interior side 3 of the outer wall 1 is provided on both sides of the partition wall 2 continuous with the outer wall 1.

It is intended to provide an internal heat insulating structure.

[0010]

[Means for Solving the Problems] As a result of earnest studies on the heat insulation structure of the partition wall continuous with the outer wall, it is found that in a normal concrete building, there are steps of about several hundred mm in columns and beams. Since it is normal and interiors are provided on the premise that such a step will occur, even if a step difference of several tens of millimeters is created by a heat insulating material, it will not be very noticeable to the resident, but rather a partition. Destruction and damage caused by an earthquake due to the decrease in wall strength becomes a problem for ensuring the safety of life property, and the reduction of sound insulation between adjacent rooms is more important in terms of privacy protection and comfort in an apartment house. The present invention has been completed in view of the fact that it has become a serious problem.

According to a first aspect of the present invention which solves the problems of the above-mentioned prior art, an inner heat insulating structure of a partition wall continuous with an outer wall is constructed by attaching a heat insulating material to the inside of the partition wall continuous with the outer wall of a building. In a structure for heat insulation, while attaching the outer wall heat insulating material covering the entire inner surface of the outer wall, the partition wall heat insulating material is attached to both side surfaces in a predetermined range from the inner surface of the outer wall of the partition wall, It is characterized in that a reinforcing member is attached to the wood mouth surface located on the indoor side of the heat insulating material for partition walls.

According to the inner heat insulation structure of the partition wall which is continuous with the outer wall, although the heat insulation material for the partition wall attached to the partition wall protrudes to the outside to cause a step, it has a better air flow than a step normally generated in a concrete building. It can be made so small that it does not become dew, and it is possible to secure strength and sound insulation while preventing dew condensation, and also to prevent damage to the cusp of the partition wall insulation material.

According to the second aspect of the present invention, in addition to the structure of the first aspect, the inner heat insulating structure of the partition wall continuous with the outer wall is any one of the partition wall, the geese, and the ceiling slab. It is characterized by that.

According to the inner heat insulation structure of the partition wall which is continuous with the outer wall, the partition wall which partitions adjacent rooms as a partition wall where the outer wall is continuous, the outer wall has a stepped shape and the partition wall is continuous, and the upper and lower walls are continuous. Even if it is applied to any ceiling slab that partitions a room, the partition wall insulation material that is attached to the partition wall also protrudes toward the room side to create a step, but it is more important than the step that normally occurs in a concrete building. It can be made as small as possible, the strength and sound insulation can be secured while preventing dew condensation, and damage to the ostium of the insulation material for partition walls can be prevented.

Further, according to the third aspect of the present invention, in addition to the construction of the first or second aspect, the inner heat insulating structure of the partition wall continuous with the outer wall is characterized in that the outer wall and the partition wall are made of reinforced concrete, reinforced concrete of steel frame, It is characterized by either reinforced concrete construction with glass fiber or precast concrete construction.

According to the inner heat insulation structure of the partition wall continuous with the outer wall, the same applies regardless of whether the outer wall and the partition wall are made of reinforced concrete, steel frame reinforced concrete, glass fiber reinforced concrete or precast concrete. In addition, although the insulation material for the partition wall attached to the partition wall protrudes to the inside of the room to create a step, it can be made smaller than the level difference that normally occurs in a concrete building, and it is possible to prevent dew condensation while increasing strength and noise insulation. It is possible to secure the property and prevent damage to the ostium of the partition wall heat insulating material.

The inner heat insulating structure of the partition wall which is continuous with the outer wall according to claim 4 of the present invention, in addition to the structure according to any one of claims 1 to 3, further comprises The reinforcing member to be reinforced is a reinforcing tape or a reinforcing plate material.

According to the inner heat insulating structure of the partition wall which is continuous with the outer wall, the ostium surface of the partition wall heat insulating material is reinforced by the reinforcing tape or the reinforcing plate material, thereby damaging the ostium surface of the partition wall heat insulating material. Can also be prevented.

As used herein, the term "end surface to be reinforced with the reinforcing tape or the reinforcing plate material" means that the partition wall heat insulating material is usually a rectangular board-like material, and the peripheral four surfaces other than the front and back surfaces are the wood opening surface. However, when it is installed on a vertical partition wall, the top and bottom vertices are not exposed in contact with the ceiling and floor, and the outer wall side of the left and right is not exposed in contact with the outer wall insulation, and the outer wall of the left and right is not exposed. The remaining one surface on the opposite side is the wood entrance surface that will be positioned inside the room when the interior is completed as a step, and when installing the insulation material for partition walls to the horizontal ceiling slab,
It is one of the four entrances that is a step and is located inside the room when the interior is completed. If the interior slab is not located when the interior is completed, such as a ceiling slab that divides the upper and lower rooms as a partition wall, the insulation material for the partition wall on the upper surface of the ceiling slab is hidden under the floor material, and Since it is not located in the room, it is not included in the wood mouth surface reinforced by the reinforcing tape or reinforcing plate material here.
