Description

DETAILED DESCRIPTION OF THE INVENTION [Industrial Application Field] The present invention relates to an eaves VFT thermal structure that has excellent heat insulation performance, can prevent dew condensation, and can provide excellent sound insulation and insulation.

[Conventional technology and its problems, etc.]

Conventionally, there are many types of roofs in which folded roofs are laid in two layers and a heat insulating material is filled in between. However, they often have a double 91t structure, which still reduces the insulation performance by half, and has the disadvantage that condensation can form on the lower surface of the lower folded roof and fall into the interior. was there.

[Means for solving problems]

Therefore, in order to solve this problem, the inventor has conducted extensive research and has laid an upper folded roof at an appropriate interval above the lower folded roof. The length of the lower folded roof is the same as that of the lower folded roof, and an eaves W-shaped door is fixed between the upper surface of the lower folded roof end and the lower surface of the upper folded roof end. By filling the space between the lower folded roof and the upper folded roof with insulation material on the inside,
It has excellent heat insulation performance, prevents dew condensation, and provides excellent sound insulation and soundproofing, thus solving the above-mentioned problems.

〔Example〕

Hereinafter, one embodiment of the present invention will be described based on FIGS. 1 to 3.

A is the lower folded roof, and B is the upper folded roof.

These folded roofs have continuous peaks and valleys,
This unit roofing material 1 is divided into two types: a joint type (see Fig. 1 and Fig. 2) in which an upper roof part 1a and a lower part 1b are provided and the roof parts 1b are sequentially tightened (see Figs. 1 and 2), and a chevron-shaped There is also a type in which the parts are simply overlapped (see Fig. 3). In addition to this, although not shown, there is also a type in which the edges of the unit roofing members are fitted with a capping material to connect them to each other.

In this way, the unit roofing material 1 is not limited to its cross-sectional shape, piece shape, etc., as long as the peaks and valleys are continuously formed when MAR is carried out.

Furthermore, for the lower folded roof A and the upper folded roof B at the same roof location, the same type of roofing material is often used as the unit roofing material 1.

This unit roofing material 1 is made to be approximately orthogonal (including orthogonal) to a structural material 2 such as a beam or a purlin, and placed on the bracket 3 of this structural material 2, and adjacent units 1 and roofing materials in the width direction. The lower folded roof A is constructed by sequentially repeating the steps 1 and 1 by tightening or overlapping each other.

At this time, in the case of a fastening type unit roof material 1, it is attached via a hanger 3a. Next, a plurality of supports 4 such as metal fittings are provided on the lower folded roof A at an appropriate interval (from respect to number +1) above the height of the lower folded roof A. In the embodiment, the tool 4 is a heat insulating bolt made of synthetic resin or the like.Then, a heat insulating material 5 made of synthetic resin foam, glass wool, asbestos, etc. is laid on the lower folded roof A. This heat insulating material 5 is often wound into a roll and coated with a synthetic resin film.The support 4.4... has an upper folded roof on top. B is laid in the same manner as the lower folded roof A. In the present invention, the length of the lower folded roof A and the upper folded roof B are configured to be approximately the same. , the length of the unit roofing material 1 of the lower folded roof A in the longitudinal direction is approximately the same as the length of the unit roofing material 1 of the upper folded roof B in the longitudinal direction. Folded roof 9 and 1 lower folded roof A
.

The lower end (tip of the eaves) of the wall 6 is provided so as to protrude outside the wall 6.

An eaves W-shaped door 7 is fixed to close the space between the upper surface of the lower folded roof A end and the lower surface of the upper folded roof B end. This eaves W-shaped door 7 has a cross section of the lower folded roof A and the upper folded roof B, that is, a shape in which the peaks and valleys are continuous.
Made of metal plate, it can be made up of multiple pieces or a single piece.

The heat insulating material 5 is filled in the space between the lower folded roof A and the upper folded roof B on the inside of this W-shaped front door 7. This heat insulating material 5 is available in low-density and high-density types.

8 in the figure is a metal plate eave front door, and the lower folded roof A
It is fixed to the underside of the eaves. 9 is eaves drainage material, 1
0 is a partition door, 11 is an eaves gutter, 12 is a gutter receiver, 13 is an eaves decorative board, 14 is a snow stopper, and 15 is a snow stopper.

In the embodiments described above, there is a case where the eaves of a roof are located below the water as a general eave part, but the same applies to the eaves part on the water side of a single-slope roof, and furthermore, the eaves at the below water side position are also applicable. The valley eaves portions where the portions are symmetrically provided are also configured in the same manner, and in the present invention, these are collectively referred to as the eaves.

Further, a heat insulating sheet made of foamed synthetic resin or the like is often pasted on the lower surface of one or both of the lower folded roof A and the upper folded roof B.

〔Effect of the invention〕

In the present invention, an upper folding plate roof B is laid above the lower folding plate roof A with an appropriate interval, and this upper folding plate roof B
The length and the nest of the lower folded roof A are made equal, and the eaves W-shaped door 7 is fixed between the upper surface of the lower folded roof A end and the lower surface of the upper folded roof B end, and this eaves W By filling the space between the lower folded roof A and the upper folded roof B with the heat insulating material 5 inside the shaped door 7, firstly, the insulation performance is superior, and secondly, the prevention of condensation is relatively good. Thirdly, it has the effect of providing good sound insulation and soundproofing.

First, the eave W-shaped door 7 is fixed between the upper surface of the lower folded roof A end and the lower surface of the upper folded roof B end, and the lower folded panel By filling the space between the roof A and the upper folded roof B with the insulation material 5, the lower folded roof A, the upper folded roof B, the eaves W-shaped door 7, and the insulation material 5 prevent the eaves from being exposed to outside air. It has an isolated laminated structure, which reduces the amount of heat loss through the flow to the outside, and increases the heat conduction resistance value, making it possible to provide an eaves insulation structure with excellent insulation performance.

Secondly, with the laminated structure in which the eaves are isolated from the outside air, there is almost no cold bridging effect at the eaves, which makes it difficult for dew to form on the back side of the lower folded roof A. , it is possible to prevent the adverse effects on the interior due to falling rings of condensation.

Thirdly, by adopting the eaves insulation structure with improved insulation performance, it is possible to simultaneously reduce external sounds and noise, and to reduce the external noise by using the upper folding plate layer as a layer B and the lower folding plate layer. The sound is reflected by the roof A and the eave insulating structure acts as a sound absorber, which has the advantage of providing good sound insulation and soundproofing.
