Description

[Detailed Description of the Invention] The present invention relates to a roof structure that is used as a simple storage area for bicycles, motorcycles, automobiles, etc., or for temporary temporary stores.

Although the above structures are not as large-scale as, for example, garages or prefabricated buildings, they are required to have a rain protection function and be strong enough to prevent them from falling over due to wind. Therefore, in the past, generally, a plurality of pillars were erected, horizontal frames were connected across the upper sides of the pillars, and roof slabs were attached to the horizontal frames.

However, when using the above-mentioned conventional technology, since there are multiple pillars supporting the roof slab, it takes time and effort to erect the pillars, and the cost is high. There was room for improvement in terms of the use of the space under the roof slab because there were multiple supports that tended to get in the way of using the space under the roof slab.

In view of the above points, the present invention has been developed to create a roof structure that has the functions of a roof in terms of strength and rigidity, is superior in construction efficiency and economy, and also allows for easy utilization of the space under the roof slab. This is what we are trying to provide.

The characteristic configuration of the present invention for providing the above-mentioned roof structure is that a roof mounting member formed by bending a single rod into a channel shape or an annular shape is provided with a ground installation part at one location in the circumferential direction, A roof slab provided with a rigid frame part around the circumference is inserted into the roof mounting member while being sandwiched from both sides in the width direction perpendicular to the longitudinal direction, and a hypothetical model passing through the installation part when installed on the ground. At positions distributed at equal or approximately equal distances with respect to the vertical line, the longitudinal intermediate portions of the portions of the rigid frame along the longitudinal direction of the roof slab are connected to the roof attachment member, and the rigid A portion of the frame part that is spaced apart from the roof mounting member toward one end in the longitudinal direction of the roof plate, and a location spaced apart from the other end in the longitudinal direction of the roof plate intersect with the imaginary vertical line of the roof mounting member. It is a point where a point or a point near it is connected via a cable.

Because the roof slab is supported by a single roof mounting member that serves as a support, this may be a factor in reducing work efficiency and increasing costs, or it may be a factor in accessing and using the space under the roof slab. The number of supports can be minimized.

Both ends of the roof slab in the width direction are connected to the roof mounting members to support the roof slab on both ends, so compared to the case where one end of the roof slab in the width direction is connected to a support and the roof slab is supported in a so-called cantilever manner. Therefore, the strength and rigidity required for the roof slab, that is, the rigid frame portion, can be reduced. Furthermore, in order to support the roof slab on the roof attachment member, the longitudinal intermediate portion of the rigid frame along the longitudinal direction of the roof slab is connected to the roof attachment member. Although it is supported in a cantilevered manner by The amount of protrusion of the portion of the roof plate that protrudes from the roof mounting member to one side and the other side in the longitudinal direction of the roof plate is both smaller than the amount of protrusion of the roof plate in the longitudinal direction of the roof plate. Requires less strength and rigidity.

In short, while adopting a type in which the roof slab is supported by a single roof attachment member, the required strength and rigidity of the roof slab can be reduced, making it possible to reduce the weight and cost of the roof slab.

In order to support the roof slab on the roof mounting member, both widthwise ends of the roof slab are placed at positions on the roof mounting member at equal or approximately equal distances from a virtual vertical line passing through the installation part of the roof mounting member. The center of gravity of the roof slab is located at or near the virtual vertical line when viewed in the longitudinal direction of the roof slab, that is, above the installation part of the roof mounting member, so that the weight of the roof slab is By suppressing as much as possible the force acting to topple the member in the width direction, the strength and rigidity required of the support can be reduced, and the weight and cost of the support can be reduced.

When the roof slab is fanned by wind, the roof slab tries to rotate around the joint with the roof attachment member, but the roof slab protrudes from the roof attachment member to one side in the longitudinal direction of the roof slab. The parts of each part and the part that protrudes to the other side are connected by cables such as wires at a distance from the roof mounting member in the protruding direction and at a location that intersects with the imaginary vertical line of the roof mounting member or is close to it. Therefore, the tension of the rope can prevent the roof slab from swinging or rotating due to the wind. In this way, since the roof slab is prevented from swinging by the tension of the rope, there is no need for the connecting part between the roof mounting member and the roof slab to have a function to prevent the rotation of the roof slab. The structure of the connecting part can be simplified. Moreover, since only the tensile force along the rope acts on the connection between the roof slab, that is, the rigid frame and the roof attachment member, and the rope, only the tensile force is considered for the connection with the rope. The structure of the connecting part can be simplified.

Therefore, according to the present invention, there is only one roof attachment part that supports the roof slab, which improves workability and reduces costs, and also allows for easy access to the space under the roof slab, use of the space under the roof slab, etc. By making the space under the roof slab easier to use, and by devising ways to attach the roof slab to the roof mounting members, we ensure sufficient strength and rigidity while reducing the weight of the roof mounting members and roof slab. It is possible to reduce costs and simplify the connection between the roof attachment member and the roof slab.
