Description

[Detailed Description of the Invention] This invention relates to insulation roofs, and more specifically to external insulation structures! Concerning roots. The purpose is to propose an insulated roof that has excellent insulation properties, durability, and is easy to construct.

Conventionally, in order to create a thermally insulated structure for a building, thermal insulation materials such as synthetic resin foam boards and glass wool were lined up on the inside of the building frame to provide insulation. However, for example, a building frame made of concrete has a high heat conduction capacity and low heat capacity, so the frame located outside the insulation material is directly affected by the outside temperature and the temperature changes drastically, making it difficult to control the indoor temperature. This required a large amount of energy. In addition, because the temperature changes in the building frame are large, large expansions and contractions occur repeatedly, resulting in cracks and fractures in the building frame and waterproof layer, shortening the lifespan of the building.

For this reason, in recent years, an external insulation structure in which insulation material is placed outside the building frame has been proposed. However, in order to create an external insulation structure, the insulation material must be firmly fixed so that it can withstand wind pressure and the buoyancy of rainwater and be stably installed. It also needs to have long-term durability and fire resistance. For this purpose, a roof with an externally insulated structure is constructed using synthetic resin foam board as a heat insulating material. It was necessary to provide a waist layer, which required time and effort to construct, difficult to repair, and had problems with durability.

This invention was made in consideration of the above circumstances, and the gist of this invention is to apply an insulating block made of an inorganic material layer integrated on at least one surface of a synthetic resin foam board to a waterproof roof structure. Lay the layers with the top side facing up, arrange a fixing frame around the periphery of the laid insulation blocks, fix them, fit a joint piece into the thickness end face between adjacent insulation blocks, and then This is a heat insulating roof characterized in that the heat insulating blocks are secured to cables stretched between edges along the joints of the heat insulating blocks via joint pieces.

The insulation block used in this insulation roof is made of a synthetic resin foam board with a layer of inorganic material such as tar or asbestos slate laminated on at least one surface.It has high insulation performance, has an appropriate weight, and is made of inorganic material. Since the foam board is laid with the layer facing up, the foam board is not directly exposed, improving weather resistance and fire resistance. The periphery S of the heat insulation blocks laid out is fixed by a fixed frame, and the blocks are integrally joined by fitting the joint pieces across the thickness end faces of each other.Moreover, the joint pieces are attached to the cables stretched along the joints. Since it is interlocked, installation stability is extremely high. In particular, this insulating block is relatively heavy and thick, so the frictional force between adjacent blocks is strong, which is combined with the effect of joining by the joint piece and fixing the peripheral edge of the cable 9. Therefore, it exhibits high stability against strong wind pressure and buoyancy even on pitched roofs.

The insulation blocks used in this insulation roof are polystyrene,
Mortar on synthetic resin foam boards such as polyurethane, polyvinyl chloride, and polyethylene.

It is made by laminating and integrating inorganic materials such as asbestos slate boards and ceramic boards. As the synthetic resin foam board, polystyrene-based ones are preferred because they have high strength, excellent heat insulation properties, and water resistance. Mortar and asbestos slate are suitable as inorganic materials because they have fire resistance, weather resistance, high density, low cost, and are easy and reliable to join with foam boards.

The foam board and the inorganic material are firmly adhered to each other using a water-resistant and durable adhesive such as epoxy adhesive, or they are integrated by pouring mortar slurry and solidifying the adhesive.

The thickness of the synthetic resin foam board is usually in the range of 25 to 100 mm, and is selected depending on the target insulation properties. The thickness of the inorganic material is usually in the range of 5 to 20 cm, and it is laminated on both surfaces or one surface of the foam board. The weight of the insulation block is 10~
50/- is suitable. If it is less than 10/-, the thickness of the inorganic material layer vIjb* will be too thick and the installation stability will deteriorate, which is not preferable. Also, 50(/-
The above is too heavy, places an excessive burden on the building frame, and is undesirable in terms of construction and material costs. Thickness is 50~
100■ is suitable. If the number of blocks is less than 50, the frictional force between the blocks arranged side by side will decrease and the installation stability will be poor.
■If the temperature is higher than that, the cost will be high, and the insulation performance and installation stability will approach saturation and the efficiency will not be good. The vertical and horizontal dimensions of a block are usually 450 x 450 m.

It is 900 x 900 ss @ degree, and if it is too small, it will take a lot of effort to lay it, and if it is too thick, it will be difficult to handle, which is not desirable.

The present invention will be explained below with reference to an embodiment shown in one figure.

Figure 1 shows a heat insulating block 1 used in this invention with a capacity of 450 mm.
It is constructed by laminating 8-thick asbestos slate J [5] on the surface of a 450 x 50 cod tile/foam board 2 and fixing it with an epoxy adhesive and integrating it. Its weight was approximately 15 noodles/d. Figures 2 and 5 show this cross-sectional block 1 as a barrier roof slab 4.

In the joiner 6, the upper and lower fiK joint pieces 8, 8 of the central support piece 7 overhang at right angles, without an I-shaped Y, and the upper joint piece 8 is divided into two in a direction perpendicular to the surface of the support piece 7. A locking groove 9 is bored that reaches up to . The joining pieces 8, 8 of this joiner 6 are fitted into the end faces of four heat insulating blocks 1 laid out side by side with their centers centered at one point, respectively, to join the heat insulating blocks.

A fixing frame 10Y is arranged on the outer peripheral edge of the heat insulating blocks 1 arranged side by side to fix the insulating blocks 1.

That is, the fixed frame 1o consists of a spring par 11 and a holding fitting 12, and the spring par 11 is located between the parabet 15 rising from the periphery of the rooftop and the insulation block 1, and is pressed into the insulation block 1v from the periphery. It is biased in the direction. Further, the presser metal fitting 12 is attached to the parabet 15 and pressed from above to the lifting bar 11'+ to fix the periphery.

Between the two opposing sides of the periphery of the insulation blocks laid out, the cable 14 made of piano wire is the junction Y of the insulation blocks 1 and 10.
The springer 60 passes through the locking groove 9 and is tensioned in two orthogonal directions at a predetermined interval. Therefore, the joiner 6 does not fall off the cable 14, and the heat insulating block 1 joined by the joining piece 8 of the joiner 6 is connected to the joining piece 8Y.

In addition, a curb block 15V is arranged along the periphery of the insulation block 1 between it and the parabet 15, and between the opposing curb blocks 16, cables 141jl made of piano wire are stretched and arranged under tension. is fixed by pressing inward from the periphery.

The cable 14 passes between the joints between the heat insulating blocks 1, 1, and extends through a piece-shaped 7 piece 17t protruding from the lower surface of the lower joint piece 8 of the jumper inner 6'. Therefore,
The joiner 6' does not come off the cable 14 and slip upward, and the heat insulating block 1 joined by the joining piece 8 of the joiner 6' is locked to the cable 14 and does not come out of the laying position. In addition, both ends of the cable 140 are connected to the curb block 1.
l[i! of anchor bolt 15 embedded in 6] lsK is fixed.

FIG. 6 shows an embodiment of a sloped insulating roof according to the present invention. The heat insulating blocks 1 are integrally joined using a joiner 6' and laid on a waterproof sloped roof 18. Presser foot 19 with KL-shaped lip on the side edge of the sloped roof 18
