Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to an insulating horizontal roofing enclosure that has particularly excellent heat insulation performance, can reliably prevent the occurrence of dew condensation, and can be constructed with a relatively simple structure.

[Conventional technology and issues]

BACKGROUND ART Conventionally, many insulating horizontal-roofed enclosures are currently being constructed, in which a heat insulating board is laid on the lower surface of an outer enclosure such as a horizontally-roofed roof or wall. Although such a structure generally has excellent heat insulation performance, it does not necessarily exhibit sufficient heat insulation performance, and has the disadvantage that dew condensation often occurs on the lower surface of the heat insulation plate. When this happens, there is also the drawback that the heat insulation performance is reduced.

[Means to solve the problem]

Therefore, as a result of intensive research in order to solve the above problem, the inventor came up with the idea of laying a lower heat insulating board on the structural material, forming opposing rising parts on the bottom, and forming both rising parts. A through-type material having a horizontal portion formed at an intermediate position, both ends of the horizontal portion protruding from the outer surfaces of both rising portions, and an upper piece formed outward from the upper end of either of the rising portions. are installed and fixed on the lower heat insulating board at an appropriate interval, and the upper insulating board is placed between the adjacent two-way receiving molds, and the inner engaging part is attached to one side edge of the main plate and the inner engaging part is attached to the other side edge. Placing metal horizontal building boards each formed with an outer engaging part on the upper heat insulating board, and locking the locking part of the hanger to the inner engaging part of the horizontal building board. This is passed through and fixed to the receiving material, and the outer engaging part of the upper horizontal building board is engaged with the inner engaging part of the lower horizontal building board to form an insulated horizontal roofing outer enclosure. By making it a body, it has particularly excellent heat insulation performance, can reliably prevent the occurrence of dew condensation, has a simple structure, eliminates the above-mentioned drawbacks, and achieves its purpose.

〔Example〕

Hereinafter, the configuration of the present invention will be explained based on examples.

1 to 3 show an embodiment of the present invention, and 1 is a structural member such as a purlin or a rim;
A plurality of them are provided at appropriate intervals on the top or side of the structure. 2 is a lower heat insulating board, which is made of a fibrous type (glass wool, rock wool, etc.) or a porous type (foamed synthetic resin, etc.), and allows a slight amount of air to pass through the lower insulating board 2 within a range that does not impair the insulation performance. Or, the air escapes into the lower heat insulating plate 2, which is configured to circulate as if breathing as appropriate depending on the outside temperature and the inside temperature. Such a lower heat insulating board 2 is laid on the structural material 1.

Reference numeral 3 denotes a long or appropriate length of through-type material made of metal or hard synthetic resin, and rising portions 3b, 3b are provided facing each other at appropriate intervals on the bottom portion 3a. A horizontal portion 3c is formed at an intermediate position between the two rising portions 3b, 3b, and both ends of the horizontal portion 3c are formed so as to protrude from the outer surfaces of both rising portions 3b, 3b. A horizontal upper piece 3d is integrally formed outward from the upper end (see FIG. 5). The through-receiving mold material 3 is placed on the lower heat insulating board 2, and the bottom part 3a and the lower insulating board 2 are fixed from the upper surface of the horizontal part 3c of the through-receiving mold material 3 with a fixing tool 4 such as a drill screw, bolt or nut. It is inserted through and fixed to the structural member 1. At this time,
The structural member 1 and the through-receiving mold member 3 are often provided so as to be orthogonal (including substantially orthogonal). The through-receiving mold members 3, 3, . . . are arranged at appropriate intervals (approximately the width of the upper heat insulating plate 5, which will be described later). An upper heat insulating board 5 made of substantially the same material as the lower heat insulating board 2 is placed and fixed on the ends of the horizontal portions 3c, 3b between the adjacent through-receiving mold members 3,3. That is, as shown in FIG. 4, one side of the upper heat insulating board 5 is first inserted and placed between the end of the horizontal part 3c of the passing mold material 3 and the upper piece 3d, and then the upper heat insulating board 5 is inserted. When it is lowered, the other side is placed on the end of the horizontal portion 3c of the adjacent through-receiving mold material 3. The upper heat insulating board 5 is laid by repeating these steps one after another.

6 is a building board for horizontal roofing, which is made of metal and has an appropriate length or length in the longitudinal direction, and when the building board 6 for horizontal roofing is viewed as a cross section perpendicular to the longitudinal direction, An inner engaging portion 6b extending inward and upward from one side (above water side) edge of the main plate 6a is formed, and an outer engaging portion 6c extending inward and downward from the other side (below water side) edge of the main plate 6a is integrally formed. (See Figure 6).

The outer engaging portion 6c is connected to the lower horizontal roofing building board 6.
It is configured to appropriately engage with the inner engaging portion 6b of. The main plate 6a is bent from one side into a flat part, a gently sloped part, and a front sloped part. Two metal plates are bent as appropriate and integrally formed. Further, as shown by the dotted line in FIG. 6, a heat insulating material 7 such as foamed synthetic resin is pasted from the lower surface of the main plate 6a of the horizontal construction board 6 to the back surface of the inner engaging portion 6b as required. The specific shapes of the inner engaging portion 6b and the outer engaging portion 6c are as shown in FIGS. 1, 3, and 6, in which an edge with a box-shaped cross section is formed from the outer end of the gate-shaped portion. The outer engaging portion 6c, which has an edge shaped like a box shape in cross section outward from the lower end of the hanging portion, is configured to fit appropriately into the inner engaging portion 6b. Further, the cross-sectional shapes of the inner engaging portion 6b and the outer engaging portion 6c of the horizontal construction board 6 are not limited to these embodiments, and may have other appropriate shapes as long as they can be engaged. But that's fine.

Reference numeral 8 is a hanger made of a metal plate or the like, and a horizontal mounting portion 8b is integrally formed from the lower end of a gate-shaped locking portion 8a (see FIG. 7).

A horizontal construction board 6 is placed on the upper heat insulating board 5. That is, the horizontal roofing building board 6 is placed so that its longitudinal direction is orthogonal (including substantially orthogonal) to the longitudinal direction of the through-receiving mold material 3. Then, while the inner engaging part 6b of the horizontal building board 6 is locked by the locking part 8a of the hanger 8, the mounting part 8b of the hanger 8 is attached to the upper piece 3d of the through-receiving mold material 3 with rivets or drill screws. etc., and then the outer engaging portion 6c of the horizontal roofing building board 6 on the upper side (water side) of this step.
is engaged with the inner engaging portion 6b of the lower horizontal roofing building board 6, and these steps are repeated in sequence to form a heat insulating horizontal roofing enclosure.

and a rising part 3b facing the bottom part 3a,
3b, and a horizontal portion 3c is formed at an intermediate position between the rising portions 3b, 3b, both ends of the horizontal portion 3c protrude from the outer surface of the rising portions 3b, 3b. A through-receiving mold material 3 having an upper piece 3d formed outward from the upper end of the rising portions 3b, 3b.
are arranged and fixed on the lower heat insulating plate 2 at an appropriate interval, the upper heat insulating plate 5 is placed between the adjacent two-way receiving mold members 3, and an inner engaging portion is attached to one side edge of the main plate 6a. 6b and a metal horizontal construction board 6 formed with an outer engaging portion 6c on the other side edge of the upper heat insulating board 5.
The inner engaging portion 6 of the horizontal construction board 6 placed on top of the
The locking part 8a of the hanger 8 is locked to b, and this is passed through and fixed to the receiving mold material 3, and the outer engaging part 6c of the upper horizontal roofing construction board 6 is connected to the lower horizontal construction board 6. By engaging and forming the inner engaging portion 6b of No. 6, the first
It has particularly excellent insulation performance and can completely prevent the occurrence of condensation.Secondly, it has a simple structure and is particularly easy to install.
It can be constructed at low cost, and thirdly, it has many effects such as good strength.

To explain these effects in detail, even if a roof is constructed with the utmost care on site, there are many repaired components on the eaves and gables, and the roof as a whole is damaged by the lower insulation board 2. Outside air enters the space between the upper heat insulating board 5, and even if the space is filled with air with a supersaturated humidity or higher (air containing water vapor), the side roofing Architectural board 6
By laying the lower heat insulating board 2 and the upper heat insulating board 5 below, the inside of the lower heat insulating board 2 and the upper heat insulating board 5 can be slightly ventilated within the range that the moisture-containing air does not impair the insulation performance, or The air escapes into the lower heat insulating board 2 and the upper heat insulating board 5, and this air circulates as if breathing, depending on the outside temperature and internal temperature, preventing oversaturated humidity and cooling the outside temperature. Even if it is, it is possible to reliably prevent dew condensation from forming on the lower surface of the lower heat insulating board 2 on the lower side of the horizontal roofing building board 6, and it is possible to prevent condensed water from accumulating on the lower insulating board 2. It is possible to provide a heat insulating horizontal roofing enclosure with extremely excellent heat insulation performance, and it can exhibit an epoch-making effect as a roof or wall. or,
The presence of the void portion means that a heat insulating air layer exists, and the heat insulating performance can be further increased. Furthermore, the presence of the metal horizontal construction board 6 on the upper surface of the lower insulation board 2 and the upper insulation board 5 creates a laminated structure of the metal plate and the insulation board, reducing the amount of heat loss from the outside. It is possible to significantly reduce the heat conduction resistance value, thereby increasing the heat conduction resistance value, and to provide a heat insulating horizontal roofing enclosure with even better heat insulation performance.

Further, the through-receiving mold material 3 forms opposing rising portions 3b, 3b on the bottom portion 3a, and both rising portions 3
A horizontal part 3c is formed at an intermediate position between b and 3b, and both ends of the horizontal part 3c are made to protrude from the outer surfaces of both rising parts 3b and 3b, and from the upper end of one of the rising parts 3b and 3b. An upper piece 3d is formed on the outside, and in order to place the upper heat insulating plate 5 between the adjacent passing mold members 3, 3, the upper heat insulating board 5 is passed through the upper piece 3d and the end of the horizontal part 3c of the receiving mold member 3 is placed. Once inserted between the upper piece 3d, the other side of the upper heat insulating plate 5 can be easily roofed by simply placing it on the end of the horizontal part 3c, and this protects against negative pressure such as wind pressure. It can be made durable enough. In addition, the through-type material 3 can be mass-produced by processing it by extrusion molding or the like.
It has the advantage that it can be provided at a low cost, and because it has a relatively large section modulus, the entire insulated horizontal roofing envelope can be made strong against external forces (tensile loads such as snow loads and wind pressure). Furthermore, since the construction board 6 for horizontal roofing was attached to the upper piece 3d of the through-receiving mold member 3 via the hanger 8, the upper insulation board 6 was attached as described above.
It can be used as a supporting piece and also as an attachment member piece for horizontal roofing architectural boards 6.

The construction is carried out sequentially from the lower lower insulation board 2 to the upper upper insulation board 5, and in particular, the upper horizontal roofing enclosure is simply engaged, so the configuration is simple.
It can be constructed easily and quickly, and furthermore, it can provide an inexpensive insulating horizontal roofing enclosure.

In addition, if the pass-through mold material 3 is made of a hard synthetic resin with low thermal conductivity, the cold bridging effect at the three locations of the pass-through mold material can be prevented and the heat insulation performance can be further improved.
