Abstract

PURPOSE:To prevent cracking due to stepping during roofing operation by forming a section filling a space generated between a batten and a position directly faced oppositely to the batten to the position in the roofing material. CONSTITUTION:Projecting sections 2B filling spaces formed among a batten and positions directly faced oppositely to the batten except a superposing section with a roofing material 2 in a lower section are formed at the positions in four in the longitudinal direction while lower end sections 2C are most heightened in the rear of the roofing material 2. Holes 2A fixed to the batten by nailing are shaped to a superposing section with the roofing material 2 in an upper section at four positions in the lateral direction. Accordingly, the upward deflection of a header centering around the upper end section of the roofing material 2 of the lower section at the time of nailing is prevented by the projecting sections 2B, thus obviating cracking due to stepping.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a structure of a roofing material used in a house or the like.

[0002]

2. Description of the Related Art This kind of roofing material is generally formed so that both the front and back sides are flat, and the roofing material is arranged by stacking from the bottom to the top along the roof plate, and is formed in the portion covered by the roofing material above. It was nailed and fixed to the base plate through the nail holes.

[0003]

As shown in FIG. 6, when the roof is roofed using the roofing material according to the above-mentioned prior art, a portion of the roofing material other than the portion superposed on the lower roofing material as shown in FIG. A space is created between the ground plate and the ground plate. For this reason,
During the roofing work, a large local moment applied to this overlapping portion causes a stepping crack, or as shown in Fig. 7, the nailing is too strong, and the fore edge is upward with the upper end of the lower roofing material as the center. Due to the bending, wind is blown into this overlapping portion, and when the wind force is strong, the roofing material may be scattered. An object of the present invention is to eliminate the above-mentioned conventional drawbacks.

[0004]

In order to achieve this object, the characteristic construction of the roofing material according to the present invention is that a space generated between the roofing material and the field board is directly formed in a portion of the roofing material that directly opposes the field board. The filling part is formed. It is preferable that a nail hole is formed in a portion that fills the space. It is preferable that the portion that fills the space serves as a guide portion for positioning the roofing material arranged below.

[0005]

[Function] Since a portion of the roofing material that is arranged in a stack from the lower side to the upper side along the field board is directly opposed to the field board, a portion that fills a space generated between the roof board and the field board is formed. This portion functions as a reinforcing material to prevent the stepping cracks and to prevent the fore edge from bending upward around the upper end of the lower roofing material when nailing. When a nail hole is formed in the portion that fills the space, it is possible to prevent cracking due to the strong driving force when driving the nail. Further, if the space filling portion is formed so as to serve as a positioning guide portion for the roofing material arranged below, the positioning of the roofing material becomes easy and the construction efficiency is increased.

[0006]

Industrial Applicability According to the present invention, it is possible to provide a roofing material which can be installed in a state of high wind resistance and which has good workability without causing a stepping crack during roofing work.

EXAMPLES Examples of the roofing material according to the present invention will be described below. As shown in FIGS. 1 to 4, a slate-based roofing material 2 having a “pentagonal” shape in plan view partially overlaps with a base plate 1 in an inclined posture from below to above along the inclination direction. In addition, the roofing material 2 on the upper side is arranged so that the position of the roofing material 2 on the upper side is shifted left and right, and the building A,
Reinforcement 3 made of sheet metal or slate, which is a so-called accessory, at the end of the roof, such as eaves B, Keraba C, etc.
The roof is constructed by nailing and attaching A, the eaves-side drainer 3B, the keraba drainer 3C, and the rain presser. That is, the roofing material 2 and the reinforcing member 3 constitute a roofing material.

As shown in FIG. 1, on the back surface of the roofing roofing material 2, between the roof roofing roofing material 2 and a portion of the roofing roof covering 2 which directly faces the roof roofing roofing material 2 other than the overlapping portion with the roof roofing roof material 2 below. While forming the protruding portion 2B that fills the resulting space,
A hole 2A for nailing and fixing to the base plate 1 is provided with an upper roofing member 2
It is formed by arranging four places in the lateral direction in the overlapping portion with. More specifically, four protrusions 2B are formed in the vertical direction so as to include the formation positions of the holes 2A.
Is formed so that its lower surface is gradually lowered toward the upper side so as to be in direct contact with the base plate 1, and the lower end portion formed at the highest position is 2C. In order to serve as a guide portion for positioning, the lower roofing material 2 is formed in a shape along the ridgeline from the apex of the pentagon.

Another embodiment will be described below. In the previous embodiment, the roofing material of the roofing material 2 is formed with four vertically projecting portions 2B for filling the space generated between the roofing material and the base plate 1 at a portion directly facing the base plate 1. However, as shown in FIG. 5, the protruding portion 2B may be partially formed in the periphery including the holes 2A at four places, and also, the overlapping portion with the lower roofing material 2 may be formed. Other than the above, it may be formed on the entire surface at a portion directly facing the base plate 1. Further, as a guide portion for positioning vertically and horizontally with respect to the roofing material 2 that is laid down below, as shown in FIG. 5, a linear projection 2C is formed on the ridge line from the apex P of the pentagon of the roofing material 2 located below. May be formed for positioning. Furthermore, the shape of the roofing material 2 is not limited to the pentagonal shape, and may be any shape. In this case, the guide portions for positioning vertically and horizontally with respect to the roofing member 2 which is roofed downward may have a shape corresponding to it. Further, the roofing material is not limited to the slate type, and can be applied to any roofing material such as Japanese straw, western straw, metal plate and the like.

It should be noted that reference numerals are given in the claims for convenience of comparison with the drawings, but the present invention is not limited to the structures of the accompanying drawings by the entry.
