Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to roof structures of buildings and structures, and particularly to roof structures of horizontal tiered roof structures. Its purpose is to form an intermediate layer between the roof substrate and roofing material that has waterproofing, heat insulation, sound absorption, moisture control, and elasticity, and to prevent corrosion of the roof substrate and roofing material, as well as to increase the surface of the intermediate layer. A roof structure that is formed into a curved surface and brought into contact with the back surface of the metal roofing material to reduce noise caused by vibration, improve strength against external pressure, easily absorb installation errors, and is easy to construct. It is to obtain.

In general, roof structures are constructed by laying roof boards on the rafters, laying a waterproof sheet on top of them, and then applying metal roofing materials either flat or horizontally.
It had a rhombus roof. However, roofs constructed in this manner have disadvantages in that they are inferior in heat insulation, soundproofing, corrosion resistance, and appearance. In other words, since the roofing material is a metal plate, it has high thermal conductivity, lacks insulation, and condensation occurs, causing the roofing material to deteriorate.
It had the disadvantage of corroding the base. In addition, metal roofing materials have the disadvantage that distortions during molding appear as irregular waves after the roofing is completed, which impairs the appearance. Furthermore, because metal roof panels are thin and do not have a structure in which they are in full contact with the underlying structure, they vibrate due to the noise of airplanes and rain, and lack soundproofing properties.

In addition, roofs with a seam structure have the disadvantage that they require skill to construct.

In order to eliminate these drawbacks, the present invention has developed a waterproof section that is constructed by installing long boards that have insulation, waterproofing, soundproofing, humidity control, and elasticity between the roof base and the roofing material parallel to the eaves. The roof is constructed by providing an intermediate layer formed in the shape of a large curved surface, fixing the surface of the board into a large curved surface, and making the metal wall roofing material follow and contact with this, engaging and placing it. In addition to suppressing the vibration of the roofing material, the outer surface of the roofing material is curved to eliminate irregular distortions in the appearance with elasticity, creating a beautiful appearance, and on top of that, the roof structure has the characteristics listed in ni1. This is a proposal.

EMBODIMENT OF THE INVENTION Below, the roof structure based on this invention is demonstrated in detail using drawing. That is, FIG. 1 (al, (bl) is a perspective view and a longitudinal sectional view showing a part of the roof structure cut away. In the figures, 1 is a rafter, 2 is a shedding board, 3 is a nail, and 4 is a roofing. (waterproof layer), 5 is the base and consists of either the roofing board 2 alone (not shown) or a structure in which a roofing 4 is laid on the roofing board 2. Each is an intermediate layer and is constructed of a structure in which a roofing board 4 is laid on the roofing board 2. Multi-level soundproofing, waterproofing, and insulation
Is (hereinafter referred to as the turtle insulation part) 7-n,, 7-n2
．． 7-n31,. 00.7-N□ is formed in multiple steps, for example, 10 steps, from the eaves to the ridge, and is placed between the base 5 and the roofing material layer to be described later.
It functions as a reinforcing and anti-condensation layer. To explain further, the heat insulating section 7 n, 1.1. ,．． 7 ni is shown in Fig. 2 (81~FC+), and Fig. 3 (al, (bl) 'f'j!, and some trees f as shown in Fig. 4.
jFibreboard, so-called sheathing insulation board 8
(hereinafter simply referred to as boards) are laid in series parallel to the eaves. Moreover, the heat insulation part 7 n+
- Mar n1 overlaps by ΔW at the upper and lower ends, and this overlapped part is fixed to the base 5 of the rafter 1 etc. with nails, and a deformed triangular gap 9 is created between the base 5 and the back surface 8a of the board 8. The formed gap 9 functions as a joint part for promoting the function of the board 8. In addition, the surface 8b of the heat insulating parts 7-n1 to 7-n1 utilizes the elasticity of the board 8 and the step of the board 8, the so-called board thickness t, Fig. 3 fa),
As shown in (b), when the board 8 is laid, as shown by the two-dot chain line, the tip of the back surface of the upper end of the base 5 and the board 8 and Δh
The surface 8b of the board 80 is formed into a curved shape by pressing the board 80 to the position indicated by the solid line where a gap occurs. This is because the roofing material of the roofing material layer (to be described later) and the board 8 are in contact with each other over a large area, suppressing the vibration of the roofing material due to the sound of rain and the sound of airplanes, and elastically absorbing distortion during molding and construction. The purpose is to erase it through deformation and create a roofing material layer with a beautiful appearance. In addition, since the heat insulating parts 7-n and 7-n are formed in the curved i-plane, the strength is also improved. In addition, the board 8 is made of high-quality wood logs made into valves, and is made of M, fiber, refined fibers, water-resistant agents, preservatives, insect repellents, asphalt, etc., and is then formed into a board. From one of the following: coated with asphalt on the surface, or impregnated with asphalt before being formed into a board, or a board made by heating and pressurizing a mixture of asphalt powder and defibrated fibers. It is what it is. In addition,
The impregnated amount of asphalt is approximately 10 to 4 from the viewpoint of waterproofing and humidity control properties.

It has multiple levels of roofing from the eaves to the ridge, corresponding to the roof. To explain further, the roofing material parts 11-n+ to 11-n are the elongated metal roofing materials (hereinafter simply referred to as roofing materials) 12 as shown in FIGS. As shown in fb), the locking part 13 of the roofing material 12 is placed on the insulation part 7-n at a position ΔW below the top end of the board 8, and its left and right ends, the so-called short ends, are aligned with the arrows. The roof is constructed by being placed and engaged in the same direction.

Note that the length L2, width W2, and height h of the locking portion 13 of the roof material 12 are determined by the dimensions of the board 8 and the overlapping width ΔW. Of course, the roof material part 11-n.

The surface of ~11-n is a curved surface, and the back surface is the board 8
A considerable portion of the surface 8b is in contact with the surface 8b. Therefore, the structure is such that there is almost no gap between the back surface of the roof material I2 and the surface 8b of the boat 8.
