Description

  The present invention relates to a structural member, and more particularly, to a structural member that constitutes a stand for installing a solar panel.

  A member for a general solar panel is made of steel, and has a cross-sectional shape that is easy to manufacture and easy to assemble. In addition, it is required to be structurally robust so that it can withstand loads and earthquakes.

Conventional structural members for mounting a solar panel include those disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 51-10626) and Patent Document 2 (Korean Registered Patent No. 10-0634895). It is used.
The conventional structural member for a gantry can be used as a member even by a structural member alone, or can be used as a closed cross-section member by combining them, and has a concavo-convex cross section in order to increase strength.
These conventional structural members are formed by bending a plate material substantially at right angles to form irregularities, and are formed as irregularities such as a convex part followed by a concave part and then a convex part. The cross section is uniform.

The structural members are arranged opposite to each other in the opposite direction, and a pair of structural members are joined using grooved steel or the like as a connecting member to form a closed cross-section structural member having an H-shaped closed space. This closed space is filled with a filler as necessary. Examples of the filler include a heat insulating material such as polystyrene foam, or a sound insulating material and a sound absorbing material.
To join structural members and connecting members such as channel steel, and structural members, joints such as rivets, ball screws, tapping screws, screw nails, bolts, or welding, or welding are integrated. To do.

Conventional structural members for a pedestal are made by bending a steel plate into irregularities and are relatively heavy. In addition, solar power generators installed near the shore are made of steel by blown salt from the sea. Since the member rusts, rust-proof coating is required. Fluorine paint is applied to prevent salt damage, but the cost is high because the fluorine paint is expensive. Moreover, maintenance of a rust prevention coating film is required.
The present invention intends to manufacture structural members from light metal, lighter than steel, and less susceptible to rusting. By adopting aluminum extrusion, the manufacturing efficiency is increased and the required strength can be obtained with a minimum of materials. The present invention provides a structural member of an aluminum embossing having a cross-sectional shape.

  Aluminum extrusion molding material, with a concavo-convex cross section, consisting of left and right convex parts and a central concave part, so that the ends of the convex parts on both the left and right sides are bulged and rounded so as not to have sharp edges The thickness of the central part of each side constituting the concaves and convexes is increased and the thickness of the central part of the bottom side constituting the concave part of the central part is thicker than the thickness of the central part of the other side. The corner of the part is a structural member to which R is attached.

  Also, a closed cross-section structural material in which the two structural members are arranged facing each other, assembled into a closed cross-section member by a groove-shaped cross-section member or an uneven member of an aluminum die extrusion molding, and a joining surface of each member is fixed with a joint tool It is.

Since the structural member of the present invention is made of aluminum, it is lightweight and can increase the efficiency of assembly work.
Compared to steel, it is less susceptible to rusting, especially the high adhesion of fluorine-based anticorrosive paints, so even if it is installed in a location where a large amount of salt is flying near the coast, it does not rust, and there is no need to use expensive paints. There is an advantage that maintenance costs such as repainting can be reduced.
In addition, since the edges at both ends of the structural member are formed in a round shape, workers are not injured at the edge more efficiently than a structural member that has been bent into a concave and convex shape. Assembly work can be performed.
Further, when the structural members are joined and assembled, the edges do not damage other members, and the scars are hardly repaired, so that work efficiency is increased.

Sectional drawing of Example 1 of the structural member of this invention. Sectional drawing of the assembly member using the structural member of the Example of this invention. Sectional drawing of the assembly member which used the Example of this invention and the channel member as the connection material.

FIG. 1 is a cross-sectional view of an embodiment of a structural member 1 of the present invention, in which aluminum is molded by embossing, and has an uneven shape composed of left and right convex portions A and concave portions B therebetween. is there. The edges 30 at the ends of the left and right convex portions are rounded so that other members and workers' bodies are not damaged by the sharp edges.
Since the edge 30 is rounded, it is possible to prevent an operator from hurting his / her hand when handling the structural member 1 or scratching other members during assembly / joining.
Since the structural member 1 is a long member having a concavo-convex cross section and is an aluminum extrusion-molded material, it can have an appropriate length in the manufacturing process.

The concavo-convex shape is composed of first to seventh seven sides 11 to 17, and in FIG. 1, the left and right are convex portions A and the center is formed in a concave portion B.
The corners of the irregularities are rounded with an R, and the central portions 21 to 25 of each outer side are made 1 to 2 mm thicker than other portions. The corner R _{2 at} both ends of the bottom 14 of the central recess is larger than the corner R ₁ of the convex, and the thickness of the central portion 23 of the bottom 14 is about 1 mm thicker than the thickness of the other sides. In addition, a groove 31 is formed in the thickness portion.

  The thickness t of the rounded edge 30 of the structural member 1 is the same thickness t as 21 or the like at the center of the aforementioned side. By using the same thickness, when the structural materials are combined as described later, the sides come into contact with each other and are integrated as an assembly member, and the strength of the structural material can be increased.

FIG. 2 is a cross-sectional view of a hollow closed cross-section assembly member 40 that combines the structural members 1 of the first embodiment of the present invention. The assembly member 40 is constructed by arranging and assembling the structural member 1 of Example 1 facing each other in the opposite direction from top to bottom and from side to side with a space therebetween, and forming a quadrangular closed section member having a concave groove in the center of each side. It is. A joining hole is formed at a location where the thick portions of the sides of each member come into contact with each other, and the structural member 1 is firmly integrated by joining with screws, bolts, or rivets.
The assembly member 40 may be filled with a heat insulating material such as expanded polystyrene or a sound absorbing material as necessary so as to adapt to the usage environment.

  In the example shown in FIG. 3, two structural members 1 are arranged opposite to each other in the opposite direction, a groove-shaped connecting member 10 is disposed therebetween, and the thickness of the central portions 21 to 25 on the outer side of the structural member 1 is increased. The thickness portion of the connecting member 10 is in contact with a certain portion, and is joined with a joining tool such as a bolt using a joining hole formed in a portion having a thick side as in the example of FIG. Is.

  The thickness t of the rounded edge 30 of the structural member 1 is the same thickness t as the above-described central portion 21 of the side. By using the same thickness, when the structural materials are combined as described later, the sides come into contact with each other, so that they are integrated as an assembly member, and the strength of the structural material can be increased.

  In the example shown in FIG. 3, two structural members 1 are arranged opposite to each other in the opposite direction, and a groove-shaped connecting member 10 is disposed between them, and the connecting member 10 has an outer side of the structural member 1 when assembled.
