Abstract

PURPOSE:To increase workability and a water-proof ability, by forming the upperside of roof boards placed on the common rafters of a roof to be stair-like for reinforcement and arranging roof tiles in rows via water-proof roof joints in the junction of the tiles placed. CONSTITUTION:The upperside of roof boards 1 placed on the common rafters of a roof is formed as a stair. Next, roof tiles 2 are arranged in rows via water- proof roof tile joints 4 on the position 1b of the roof boards 1. In this way, roofing work can be easily carried out even by amateurs.

Description

DETAILED DESCRIPTION OF THE INVENTION (Field of Industrial Application) This invention relates to an improvement in a roof construction method.

(Prior art and its problems) Conventionally, when constructing a roof, a flat shedding board is laid on the rafters, which are the structural members of the roof, a base material is further laid on this sheath board, and then the base material is Tiles are arranged in rows on the top side of the roof, and it is necessary to fix the roofing board and base material separately, which poses a problem in that the number of construction steps increases and work efficiency is poor.

(Means for Solving the Problems) The present invention has been devised in view of the above conventional problems, and aims to provide a roof construction method with good workability. A roofing board having a step-like reinforcing part is laid on the rafters of a roof, and roof tiles are arranged in a row on the reinforcing part of the roofing board via waterproof tile joints.

(Function) When the field board manufactured in a factory etc. is transported to the site and laid directly on the rafters, which are the structural members of the roof, a step-shaped reinforcement part is formed on the top side of the field board. Therefore, tiles can be easily installed in rows along this stepped reinforcement part, and when tiles are installed in rows, waterproof tile joints are placed on the bottom side between the tiles to create a waterproof structure for the roof. It can be constructed in a good manner, and there is no need to lay base materials and ribs like in the past, simplifying construction.Moreover, since the roofing board is reinforced with reinforcement parts, it has high strength. It is possible to build a roof structure.

(Example) Hereinafter, one embodiment of the present invention will be briefly described with reference to the drawings.

FIG. 1 is a perspective view of the structure of the roof, FIG. 2 is an enlarged perspective view of the main part with tiles arranged in rows on the roof board, and FIG. 3 is a side view of the structure of FIG.

In the figure, the field board 1 is a factory-produced plywood or wood chip cement board, and has a horizontal length of 180 mm, for example.
0ml, vertical length is 900n! The reinforcing portion 1 is formed in a stepped shape on the upper surface side.
a, la, and la are formed, and the upper surface of each reinforcing portion 1a is a mounting surface 1b on which a roof tile can be placed.
The upper end portion of b is a raised contact surface 1c, lc, lc.

The roofing board 1 formed in this way can be carried to the site and laid directly on the rafters T, T, T, which are the structural members of the roof, and tiles 2 can be placed on the roofing board 1 that has been completely laid. When arranging the tiles 2 in a row, the tiles 2 can be arranged in a row on the above-mentioned placement surface 1b while laying waterproof tile joints 4 on the lower surfaces of the side edges of each tile 2. At this time, the upper ends of the roof tiles 2 can be easily positioned by bringing them into contact with the contact surface 1c, and a large number of roof tiles 2 can be arranged in rows along the contact surface 1c without requiring any skill. Furthermore, the waterproof tile joint 4 is made of aluminum.

It is formed into a plate shape from a metal plate such as iron or copper, or a resin such as vinyl chloride or acrylic, and a large number of grooves are formed along the longitudinal direction on the top side of the plate. It allows rainwater to flow downward.

By installing the waterproof tile joint 4 between each tile 2, 2 in this way, even when rainwater enters between the tiles 2, 2, the rainwater will flow down through the waterproof tile joint 4. Good waterproofness can be ensured. Furthermore, the field board 1
If it is made of wood chip cement board, it can have a fire prevention effect, and furthermore, the above-mentioned placement surface 1b and contact surface IC are roofed with asphalt paper, etc., and the upper surface side of the field board 1 is treated with ribs. If you do so, you can obtain a better relief effect.

In this way, in this example, the roofing board can be laid directly on the rafters of the roof, and tiles can be laid one after another on the roofing board through waterproof tile joints, so that the top surface of the roofing board has a stepped shape. Because the roof tiles are perfectly formed, positioning of tiles is easy and construction workability is extremely good.

Further, unlike the conventional method, a base material is not required, and the number of construction steps can be reduced accordingly, thereby improving workability in roof construction.

(Effects of the Invention) In the roof construction method of the present invention, a sheathing board having a stepped reinforcing portion on the upper side is laid on the roof rafters, and a waterproof tile joint is installed on the reinforcing portion of the sheathing board. By arranging intervening roof tiles in a row, the roofing boards manufactured in a factory etc. are laid directly on the rafters of the roof, and the roof tiles are directly laid in rows on the roofing boards via waterproof tile joints to construct a roof. This greatly improves the workability of roof construction by omitting the work of laying the base material as in the past.Moreover, the roof tiles can be installed along the reinforcing section formed in a step-like manner on the upper surface of the reinforcing plate. can be arranged in a row in good condition without requiring any skill, further improving workability. In addition, waterproof tile joints ensure waterproofness,
It has a good roof structure binding effect.
