Description

DETAILED DESCRIPTION OF THE INVENTION A waterproof, heat-insulating layer having waterproof, heat-insulating, and moisture-controlling properties is formed in a stepped roofing pattern to prevent corrosion of the base material and roofing material, and the roofing material is coated with the waterproof, heat-insulating layer. This article relates to a method of constructing a roof with a step reinforced with.

An embodiment of the roof construction method according to the present invention will be described in detail below with reference to the drawings. Figure 1 faJ and fbJ are explanatory diagrams showing roofs thatched by the above method, fbJ is a partially cutaway perspective view, and fbJ is l in the fbJ diagram.

In the figure, 1 is a rafter, 2 is a sheathing board, 3 is a nail, 4 is roofing (waterproof layer), and 5 is a base, which is either the core of the sheathing board 2 or a structure in which a roofing 4 is laid on the shedding board 2. It is what it is. 6 is the roof ratio in Figure 2 (al~'(
It has the cross-sectional shape shown in ``'' and has a stepped roofing structure, and its height h is determined by the thickness of the components of the waterproof insulation layer 7, the so-called thickness t of the waterproof insulation board 8, and the reinforcing rods. 9 height H

Furthermore, to explain the waterproof heat insulating layer 7 (hereinafter simply referred to as a heat insulating layer), the heat insulating layer 7 is a rectangular wood fiberboard, impregnated with asphalt, or coated with a waterproof heat insulating board (hereinafter simply referred to as A plurality of boards (referred to as boards) are arranged in series in the direction of the girder, with the side end surfaces of their short sides touching or in a joint formed with a slight gap, through t, and from the upper end toward the eaves.

The waterproof and insulating part, in which the strong bar 9 is fixed parallel to the long side of the board 8, is constructed in a stepwise manner from the eave to the ridge as shown in Figs. 6(a) to (C).
The roof was constructed as shown in the figure. In addition, the above board 8
For example, width W = 150 to 9001 nm, length L = 20
The size is 0 to 3636 m, and the thickness is t-10 to 30 mm. Moreover, in order to function as a waterproofing material, a heat insulating material, a reinforcing material, and a humidity control material, the board 8 is made by pulping high-quality wood raw wood, which is further defibrated and refined, and contains water-resistant agents, preservatives, insect repellents, etc. It is made from asphalt, etc.

The amount of asphalt impregnation, or coating, determines its waterproofness,
The content is set at 10 to 40% (weight ratio) in consideration of humidity control properties.

This is because if the amount of asphalt impregnated is less than 10%, it will lack waterproofness, and if it is more than 40%, it will not have moisture control properties.
This is due to the fact that so-called breathability may not be as expected, and there is a risk of a decrease in heat insulation properties.

In addition, the reinforcing bar 9: C Figure 5 (al~(C)

Next, the construction method of the heat insulation layer 7 will be explained.
As shown in Figure (a), the wide and small dancer 11 is fixed to the eaves of the base 5. Thereafter, the boards 8 are laid and fixed in series along the girders with the short side end surfaces of the boards 8 in contact with each other. For example, the waterproof insulation part 7 of the first stage is called 8 for convenience as board 8 of nl.

0 Boards (not shown) are laid in the order of 8-nl-n, and a reinforcing bar 9 is fixed at a position spaced by a width of Δl from the upper end in the direction of the eaves so as to be perpendicular to the rafter 1 via nails 3. A first stage waterproof heat insulating section 7-n1 is formed. Next K (b)

(as shown in the cl figure, the reinforcing rods 9 are fixed to form the second stage waterproof heat insulating part 7-n2.) In this way, the heat insulating layer 7 is It is formed in n stages from the eave to the ridge. At this time, a void 12 having a triangular longitudinal section is formed between the base 5 and the back surface of the board 8.

Next, the roof construction method according to the present invention will be explained. First, a heat insulating layer 7 is formed on the base 5 in the order shown in FIGS. 6(a) to (cl). Next, the roofing material 6 is Lay the waterproof insulation section 7-n1 on the board 8. That is, lay and fix the first stage 9.Ticket offering society≠6-n1-n, which is called for convenience, on the board 8.Next, the second stage The roof portions 6-n2, 3rd tier roof portions 6-n31., .

What has been described above is only one embodiment of the roof construction method according to the present invention, and includes forming a recess on at least one of the upper, lower, left, and right edges of the board, or interposing adhesive tape in the joint between the boards 8. , fixing the board 8 and the reinforcing bar with adhesive,
It is also possible to create a waterproof and heat-insulating layer by planting caulk between the upper and lower boards.

As mentioned above, according to the roof construction method according to the present invention,
Since it is possible to reliably form a heat insulating layer with heat insulating, waterproof, and moisture control properties between the base and roofing material, no condensation occurs and corrosion of the base and roofing material can be prevented. ■By forming a void with a triangular vertical cross section between the heat insulating layer and the base, the humidity control function of the heat insulating layer can be promoted.

■The insulation layer uses the thickness of the board as a step, and has recesses formed at the left and right ends, so it functions as a ruler when installing roofing materials, allowing you to easily check the roofing materials and construction. It becomes easier.

■Since the roofing material is mounted and fixed on the insulation layer, 1, ・: 1
.

Can withstand sufficient external forces. ■Since the roofing material is constructed in tiers, it is possible to create a three-dimensional exterior with high efficiency.
Moreover, it can be formed without requiring any skill. ■It has features such as being able to be applied as is when roof renovations are performed.
