Abstract

PURPOSE: To greatly improve the waterproof and a designing property of a new roof by making a low gradient (6.06cm or less) of existing roof at a selective gradient of 7.6cm or more to form a new foundation. CONSTITUTION: A new rafter 10 which is formed out of two or more members is fixed on a low gradient of existing roof 1 at a prescribed pitch from a ridge to eaves so as to locate its top 11 on a target gradient line. A new foundation material 17 is placed and fixed to the top of the rafter of new gradient to form new eaves and a verge foundation and then a new roof material 20 is roofed from the eaves to the ridge.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION The present invention can be applied to existing low pitch roofs,
A roof renovation method to make a new roofing material with a special roof rafter and a new roofing material made of metal for thatched roof to make the roof a waterproof and soundproof roof with a slope of 2.5 inches or more. It is about.

[0002]

2. Description of the Related Art Generally, in order to renovate a roof with a slope of 2 inches or less into a roof with a stepped structure, a construction method is used in which a base with a predetermined slope is formed on the existing roof with a mini shed and then a new roof is constructed. Met.

[0003]

However, this mini-roof structure has a completely new base structure for the roof, requires a long period of time for construction on a high roof, and requires various materials and many artificial materials. The cost was significantly increased. further,
In order to fix the new roof structure and the existing roof, it was necessary to drive them firmly because of their strength, and it was necessary to prepare metal fittings for that purpose.

[0004]

In order to eliminate such drawbacks, the present invention uses a new rafter, which is a main part of a new roof base, by using two special members to cope with a slope of 2.5 inches or more. We propose a roof renovation method that allows a new roof to be constructed by applying a light-weight metal thatched roofing material as a base.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the roof repairing method according to the present invention will be described in detail below with reference to the drawings. That is, FIG. 1 is a typical example of the roof repairing method according to the present invention,
For example, it is an explanatory view in which a new roof 4 made of a metal roofing material for terraced roofs is configured on an existing roof 1 of a roofing tile.

More specifically, the existing roof 1 has a roof tile roof,
They are flat roofs, new roof tiles, and other existing roofs 1 and function as a base of a new roof 4 without removing the existing roof 1.

FIG. 2 is an enlarged cross-sectional view showing the eaves front portion in an enlarged manner. The eaves portion is composed of two layers, an old eaves portion 2 and a new eaves portion 3.
The new eaves part 3 is formed from the arabesque stopper 5 and the repair arabesque stopper 6 on the top, and the ridge 7 is constructed by removing the existing ridge (not shown) and newly using the purlin 8 and the wrapping cover 9. is there.

Reference numeral 10 denotes a new rafter, as shown in FIG. 3, which is at least two members such as an L-shaped angle 12 and a slope forming body 13.
And a fastener 15 such as a bolt, a rivet, and a screw, and a new roof substrate 16 described later is mainly mounted.

To explain further, the L-shaped angle 12 is made of one kind of metal and resin as shown in FIG. 4, and its cross section is a vertical piece 12a and a horizontal piece-shaped mounting portion 12b, a circle, an ellipse, and a cross. And the mounting holes 12c. The mounting portion 12b is for fixing one L-shaped angle to a rafter (not shown) of the existing roof 1 via fasteners 15 such as nails and bolts.

The slope forming body 13 includes a slope surface 13a and a top surface 11.
The vertical piece 13b, the fixed piece 13c, and the mounting hole 14 are mainly formed of a metal material or a hard resin material in a dimension corresponding to a gradient of 2.5 or more as shown in the figure.

Although the mounting hole 14 is formed horizontally in the drawing, it may be formed such that the center thereof is located on the gradient line A of the horizontal line α ₁ or the angle θ. Further, a gradient of at least 2.5 inches or more can be formed, and a bolt, nut, or
The size can be adjusted with nails and rivets.

The new roof substrate 16 is the top surface 1 of the new rafter 10.
1 is composed of a new base material 17 such as plywood, siding insulation board, wood wool cement board, etc., a waterproof sheet 18 such as asphalt felt, a spacer 19 and a backup material 21. The spacer 19 is formed as shown in FIG. It is composed of a batten forming the first step and a molded body made of resin, metal or the like for preventing the new roofing material 20 from rattling.

The novel roofing material 20 is preferably a lightweight roofing roofing material which is lightweight, waterproof, easy to construct, and has a three-dimensional appearance. Of course, a general-purpose roofing material can also be used.

The new roof 4 has a new roofing material 20 which is roofed on a new roofing base 16 and, in case of geckos or the like, is finished with an accessory if necessary.

Next, the construction sequence of the roof repairing method according to the present invention will be described with reference to FIGS. First, it is assumed that the existing roof 1 (gable) has a slope of 2 dimensions, and this has a slope of 3 dimensions, and the new roof material 20 is formed on it.

Therefore, a new rafter 10 is set in accordance with a set slope, for example, three dimensions, and fixed on the existing roof 1 of the roof tile roof from the ridge in parallel to the eaves with a nail or the like at a pitch of about 455 mm. .

Next, a new base material 17 made of plywood and a waterproof sheet 18 are laminated and fixed on the new rafter 10 in this order. Next, the arabesque stopper 6 for repair is fixed to the old eaves section 2 by the arabesque stopper 5, and the spacer 19 is fitted to this. Although not shown in the drawings, the keraba side is equipped with a keraba base having a two-member structure to close the gap formed by the difference in gradient.

Next, a new roofing material 20 made of metal for the stepping as shown in FIG. 6 is roofed as shown in FIG. 2 via the backup material 21, and the fixing portion 20a is fixed with the nail B. Therefore, in order to form the new roof 4, such work is sequentially and repeatedly performed from the eaves toward the ridge. After that, the purlin 8 and the purse cover 9 are attached to the ridge portion in this order, and the unillustrated keraba is attached with the unillustrated keraba cap each time the new roofing material 20 is constructed.

The above description is merely one embodiment of the roof repairing method according to the present invention, and the structure shown in FIGS. 7 (a) to 7 (c) can be adopted. That is, (a) is a new rafter 10 formed in a U-shaped groove into which the tip of the vertical piece 12a of the L-shaped angle 12 is fitted, and (b) is a batten C in the inner recess of the slope forming body 13. New rafter 10, (c) Figure is 3
As a member, a U-shaped body 13d having a top surface 11 is used as a fastener 1
It is a new rafter 10 integrated in 5. The L-shaped angle 12 may be formed in a gradient shape.

[0020]

As described above, according to the roof repairing method of the present invention, it is possible to form a roof base having no problem in waterproofness with a small number of members even with a low slope roof. The new rafter is lightweight and can handle multiple slopes with one type. The target gradient can be obtained simply by changing the fastening position. The thatched roof can form a beautiful appearance that matches the slope. The construction can be configured as a kit without requiring a new roof base and a new eaves section. There are characteristics and effects.
