Description

TECHNICAL FIELD The present invention relates to a base material for a curved roof of a building including a cover for an aircraft and the like, and a roof using the base material.

[Conventional technology]

Conventionally, as shown in FIG. 20 and FIG. 21, a metal plate such as a steel plate is bent, and a face plate portion having a flat surface (1) Reinforcing portions (2) along the longitudinal direction at a plurality of positions in the width direction of the back surface There was a deck plate in which the (lower rib) had an isosceles triangular cross section. The deck plate has flat portions (3) formed by crushing the reinforcing portions (2) at both ends, and engaging portions (4), (5) for engaging the deck plates adjacent to both sides. Is formed.

In addition, as shown in FIGS. 22, 23, and 24, a steel plate or the like is bent, and the face plate portion (6) having a flat surface is folded back to the back surface to form a double-sided reinforcing portion having an angled cross section ( 7)
There was also a deck plate in which the flat part (8) was formed by crushing the reinforcing part (2) at both ends while forming the flat part (8).

Using the deck plate as described above as a base material for roof, as shown in FIG. 24, the flat parts (8) (or (3)) formed at both ends are supported and fixed on the beam (9) of the building. It is possible to construct a concrete roof by arranging reinforcing bars on the face plate portion (6) (or (1)), embedding the reinforcing bars and pouring concrete. The deck plate is left on the concrete roof without being removed even after the concrete is hardened.

[Problems to be Solved by the Invention]

Conventional deck plates are not suitable for use as a base material for a curved roof such as a kamaboko type, because each of the deck plates is formed by bending a single steel plate or the like and integrally forming a reinforcing portion on the back surface of the face plate portion. It was That is, the conventional deck plate is curved along the longitudinal direction into an arc shape,
In addition to requiring a large amount of force, it is difficult to machine the deformed reinforcing part, which causes distortion due to concentrated stress and cracks in materials such as steel plates, which further increases the clearance at the upper edge of the reinforcing part, resulting in a deck plate. There is a problem that the concrete poured into the surface enters the reinforcing part in the gap, and if a deck plate with a flat surface that is not curved is used as the base material for the roof, the corners as shown in Fig. 24 There is a problem that it is difficult to obtain a curved roof such as a semi-cylindrical shape because the deck plate (3) is erected between the beams (9) in a cross-sectional shape having a part, and the appearance is impaired.

The present invention solves the above-mentioned problems, and it is possible to accurately and relatively easily curve along the longitudinal direction without causing distortion or cracks, and to provide a curved roof with a good appearance. An object of the present invention is to provide a base material for a curved roof that is obtained with good workability and a curved roof using the base material.

[Means for Solving the Problems]

The curved roofing base material of the present invention has mounting portions along the longitudinal direction formed at a plurality of positions in the width direction of the back surface, and a face plate curved along the longitudinal direction, and flanges on both outer sides of the side edge portions of the surface. It has a reinforcing member that protrudes, is curved along the longitudinal direction with a curvature similar to that of the face plate, and further has flat portions formed at both ends, and supports the flange of the reinforcing member on the back surface of the mounting portion of the face plate. It is fixed and a plurality of the reinforcing members are arranged along the longitudinal direction of the face plate.

Further, the curved roof according to the present invention, the flat portion provided at the end of the curved roof base material is supported and fixed on a beam, the base material is erected between a large number of the beams, respectively, Connecting the opposite edges, arranging a large number of the base materials side by side in the width direction, placing reinforcing bars on the base material and the beam and placing concrete, or on the entire surface of the base material and the beam. It has been waterproofed.

[Action]

The base material for a curved roof according to the present invention has a face plate and a plurality of reinforcing members as separate members, and these may be bent separately, and therefore includes a process of bending in an arc shape along the longitudinal direction. Also, it can be easily and accurately machined with a relatively small pressing force, and since it is enough to fix the face plate curved along the longitudinal direction and the reinforcing member curved along the longitudinal direction, distortion and cracks are less likely to occur. Since the surface of the reinforcing member is closed by the face plate, even if concrete is cast on the base material, the concrete does not enter the reinforcing member.

Further, the curved roof according to the present invention, by arranging a large number of beams according to the length of the base material at a predetermined position in advance,
A flat part provided at the end of the base material is supported and fixed on the beam, and a large number of the base materials are installed between a large number of beams, and the shape is smoothly curved such as a semicircular cross section as illustrated in FIG. 7. Since the base material can be laid on the beam, the work until the base material is laid on the beam can be performed easily and in a short time. Furthermore, since a curved surface with almost no gap can be formed between the beam and the laid base material, concrete can be placed on this curved surface or waterproofing work can be easily done, and the curved surface is smooth, The finished curved roof has no corners and has a good appearance.
