ABSTRACT:
This patent application claims priority based on an Australian Provisional patent application, PQ3763 filed on Oct. 29, 1999, the contents of which are incorporated herein by reference.
BACKGROUND OF THE INVENTION
1. Field of the Invention
The present invention relates to a structural member. More particularly, the present invention relates to a structural member, method for manufacturing a structural member, a structural unit, and a method for manufacturing a structural unit.
2. Description of the Related Art
In the case where steel material is used for constructing a structure such as a house, building, or a warehouse, a channel section that has a C-shaped cross-section is generally used as a steel material. The channel section is generally formed by bending a steel plate, the thickness of which is usually from 0.8 to 1.5 mm, to have a C-shaped cross-section. The framework of a building can be constructed by using the channel section as a column, beam and diagonal brace and by combining the channel sections. However, the weight of the channel section must be high to have the necessary strength. Moreover, it is difficult to position a plurality of the channel sections when combining and connecting a plurality of channel sections with each other .Therefore, it is difficult for an ordinary person to construct a building using a channel section. The cost for constructing a structure is therefore expensive.
Therefore, to increase the strength of the steel material, which is used for constructing a Structure, and to reduce the cost of constructing the structure, the above-mentioned channel section problems must be overcome.
SUMMARY OF THE INVENTION
Therefore, it is an object of the present invention to provide a structural member and method for manufacturing a structural member which overcomes the above issues in the related art. This object is achieved by combinations described in the independent claims. The dependent claims de fine further advantageous and exemplary combinations of the present invention.
According to the first aspect of the present invention, a structural member for constructing a structure comprises: a pair of structural elements, each of which includes three channels opening alternately towards opposite directions and has a substantially uniform cross section along a longitudinal direction; and a connecting member which connects the pair of structural members. The structural member may further comprise a filling member provided in a space formed by the pair of structural elements and the connecting member. Expanded polystyrene may be used for the filling member.
Each of the three channels of the structural element may be substantially rectangular. The structural element may have first, second, third, fourth, fifth, sixth, and seventh substantially rectangular planar portions, neighboring faces of which are substantially perpendicular to each other. Each of the widths of the three channels may be substantially equal. Each of the heights of the three channels may be substantially equal The structural element may be made from metal. The structural element may be made from high-tensile steel.
The pair of structural elements maybe aligned and connected to each other by the connecting member such that each of the side channels of the three channels of one of the structural elements faces the corresponding aide channels of another the structural element, respectively. The pair of structural elements may have pair of the connecting members; and the planer portions of each of the pair of structural elements, which are corresponded to each other, may be connected to each other by the pair of connecting members.
The structural element may have a concave part, which connects the structural element and the connecting member. The structural element may have a rivet, a drilling screw, a tapping screw, a screw nail, a bolt, or a welding, which connects the structural element and the connecting member.
The connecting member may be a pair of channel sections, each of which has one bottom face and two side faces. The two side faces of one of the channel section of the pair of channel sections may engage with the inner face of the second planar portions of each of the pair of structural elements; and the two side faces of another the channel section of the pair of channel sections may engage with the inner face of the sixth planar portions of each of the pair of structural elements.
The bottom face of one of the channel section of the pair of channel sections may engage with each of the third planar portions of the pair of structural elements; the bottom face of another the channel section of the pair of channel sections may engage with each of the fifth planar portions of the pair of structural elements; and a space having a substantially rectangular cross section is formed by the pair of channel sections and the pair of structural elements. The structural member may further comprise a filling member provided in a space formed by the pair of structural elements and the connecting member. The structural member may constitute a straining beam or a column of the structure.
The bottom face of one of the channel section of the pair of channel sections may engage with each of inner faces of the first planar portions of the pair of structural elements; the bottom face of another the channel section of the pair of channel sections may engage with each of the inner faces of the seventh planar portions of the pair of structural elements; and a space having a substantially H-shaped cross section may be formed by the pair of channel sections and the pair of structural elements. The structural member may further comprise a filling member provided in a space formed by the pair of structural elements and the connecting member. The structural member may constitute a main beam of the structure.
Two side faces of one of the channel section of the pair of channel sections may engage with the outer faces of the second planar portions of each of the pair of structural elements; and a bottom face of one of the channel section of the pair of channel sections may engages with the outer faces of each of the first planar portions of the pair of structural elements; and two side faces of another the channel section of the pair of channel sections may engage with the outer faces of the sixth planar portions of each of the pair of structural elements; and a bottom face of another the channel section of the pair of channel sections may engage with the outer faces of each of the seventh planar portions of the pair of structural elements; and a space having a substantially H-shaped cross section may be formed by the pair of channel sections and the pair of structural elements.
The structural member may further comprise a filling member provided in a space formed by the pair of structural elements and the connecting member. The structural member may constitute a main beam of the structure.
The connecting member may be a pair of steel plates, each of which has a substantially rectangular plan. One of the steel plates of the pair of steel plates may engage with the third planar portions of each of the pair of structural elements; and another steel plate may engage with the fifth planar portions of each of the pair of structural elements; and a space having a substantially rectangular cross section may be formed by the pair of steel plates and the pair of structural elements. The structural member may further comprise a filling member provided in a space formed by the pair of structural elements and the connecting member The structural member may constitute a straining beam or a column of the structure.
One of the steel plate of the pair of steel plates may engage with the inner face of the first planar portions of each of the pair of structural elements; and another steel plate may engage with the inner face of the seventh planar portions of each of the pair of structural elements; and a space having a substantially H-shaped cross section may be formed by the pair of steel plates and the pair of structural eleme
