JP2007032235A - Composite heat insulating material using shape maintaining plate of flocculent heat insulating material in building - Google Patents

Abstract

<P>PROBLEM TO BE SOLVED: To maintain the heat insulating performance of a flocculent heat insulating material by eliminating the lowering of partial heat insulating performance due to nonuniform thickness caused when the flocculent heat insulating material of a natural material is installed or caused resulting from its mounting method using nails, hooking caused by the hooking of the heat insulating material from the front, and the heat link of nails, preventing the heat insulating material from falling by its own weight, and fitting the flocculent heat insulating material between framework materials. <P>SOLUTION: A converted paper with an air layer is bent zigzag and disposed as a core between the flocculent heat insulating materials with a specified thickness to form a composite heat insulating material. The composite heat insulating material is fitted to the framework material by utilizing its extensibility by its elastic deformation property. Then, the heat insulating material is hooked between the framework materials from the end part of the core to the side of the framework material by using nails. <P>COPYRIGHT: (C)2007,JPO&INPIT

Description

  The present invention maintains the heat insulation performance of the cotton-like heat insulating material and the initial laying shape, and at the same time allows the long-term maintenance performance to be exhibited and at the same time, by combining the processed paper which is a natural material, at the time of disposal It constitutes a heat insulating material that does not need to be disposed of separately.

As heat insulating materials for buildings, chemical products such as polystyrene, glass fibers such as glass wool, and natural materials such as wool are used.
Those using polystyrene, glass wool, etc. can be processed into a plate shape, or those with a certain level of strength, such as glass fiber, can be kept in their shape by placing them in a bag. Is possible.

  However, since a natural material such as wool made of cotton is used as a heat insulating material, its initial shape cannot be maintained over a long period of time, and is directly fastened to a wall surface using nails or the like.

  Further, by directly fastening the nail to the wall surface material, the attached portion loses the thickness of the cotton-like heat insulating material, so that the original heat insulating performance possessed as the heat insulating material cannot be exhibited.

  Also, because the nail is made of iron and has a high thermal conductivity, the nail has a high thermal conductivity, and the nail becomes a thermal bridge and is likely to cause condensation.

Problems to be solved by the invention

  The heat insulation performance that was created to prevent the deterioration of the heat insulation performance due to such a fastening method, the deterioration of the heat insulation performance due to the instability of the material of the cotton-like heat insulation material, and to maintain its original performance while maintaining a stable shape. It is a composite heat insulating material having a three-layer structure using a paper holding plate that holds the form.

Means for solving the problem

  A three-layer structure with a uniform thickness by attaching a paper-like heat insulating material to the center of the cotton-like heat insulating material, folding a paper holding plate with a laminated air layer formed at regular intervals. To form a composite insulation.

  Furthermore, it is not necessary for the composite heat insulating material composed of the cotton-like heat insulating material and the heat insulating material holding plate to be directly fastened to the face material constituting the wall or floor, and the holding plate that contacts the shaft assembly material at both ends of the cotton-like heat insulating material holding plate. It can be fastened directly or directly with a nail or the like from the ear part to the shaft assembly on both sides.

The invention's effect

  According to the present invention, there is no need to fasten directly to the wall, floor surface material or the like from the front surface of the heat insulating material by a nail or the like, and the heat insulation generated by the fixing from the front surface of the heat insulating material or the nail or the like. It is possible to prevent a decrease in heat insulation performance due to uneven thickness of the material.

  Furthermore, by using processed paper for the shape holding plate of the heat insulating material, even when it is discarded, it can be discarded without the need for separation because it is wool and paper.

  The drawing is an embodiment of the composite heat insulating material inside the wall of the building according to the present invention, in which 1 is a pillar (shaft assembly) in contact with the composite heat insulating material, D is a processed paper heat insulating material holding plate, a and b are cotton-like heat insulating materials.

  The processed paper heat insulating material holding plate (FIG. 1) has a three-layer structure of two upper and lower flat papers D ′ and a core paper E bent zigzag, and air is also held in the space of the core material. Therefore, this heat insulating material holding plate made of processed paper also has heat insulating performance.

  Adhere cotton-like heat insulation material b from the inner side to the valley part F folded in a zigzag, and paste the cotton-like heat insulation material for each valley, and paste the cotton-like heat insulation material on the back as well. A cotton-like heat insulating material a of the same material having a uniform thickness is pasted on the apex portions of the peaks, and the cotton-like heat insulating materials a, b-processed paper heat insulating material holding plate D-cotton-like heat insulating materials a, b Constructs a layered insulation.

  This three-layer structure heat insulating material is directly attached to the shaft assembly material from both ends G which are the ears of the processed paper of the core material with nails (M) or the like, and the attachment portion is attached by the elasticity of the processed paper heat insulating material holding plate. In close contact with the shaft assembly material, the cotton-like heat insulating material a covers and conceals the shaft assembly mounting portion of the processed paper heat insulating material holding plate. After the construction, the mounting portion is not exposed to the surface, and the heat insulating performance can be sufficiently exhibited.

  In addition, by using this processed paper heat insulating material holding plate D as a core material, due to its stretchability due to its elastic deformation performance, it is possible to ensure heat insulation performance by only being fitted between the shaft assembly materials due to its elasticity. Since it is possible to maintain the form by itself, it is possible to provide a high-performance heat insulating material having many advantages such as being incorporated in a panel in advance in a factory or the like to be a heat insulating panel.

Claims (1)

Usually, glass wool, extruded polystyrene, etc. are generally used as heat insulating materials for buildings, but recently natural materials (wool etc.) are processed into cotton and laid in spaces such as walls and floors. It is fixed by using etc.
A processed paper (corrugated cardboard, etc.) with an air layer that is easily deformed and deformed into a core material of cotton-like heat insulating material is bent into a corrugated, zigzag, rugged shape, etc. A cotton-like heat insulating material is pasted on the back, and an integrated composite heat insulating material is constructed using the elastic deformation performance of the processed paper and a stretchable cotton-like heat insulating material. Fastening is not directly attached to the face material, but a core material Fastening from the edge portion of the end portion to the inner surface of the shaft assembly with a nail or the like eliminates the uneven thermal insulation performance due to the nonuniform thickness of the thermal bridge of the nail or the heat insulating material of the fastening portion.
