DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a long structural member used for columns and beams of a building or the like.

[0002]

2. Description of the Related Art Conventionally, a system using a curtain wall as an outer wall of a building has been known. The curtain wall is attached to the building by mounting a cubicle between the upper and lower floors of the building and fixing panels to the cubicle.

[0003]

The curtain wall is usually made of H-shaped steel or the like.
When a mold steel or the like is used, the workability deteriorates, and in order to obtain the required strength, an H-shaped steel having a relatively large cross section is used, so that there is a problem that the occupied space becomes large.

[0004] For this reason, the present applicant has filed Japanese Utility Model Application No. 3-52672.
As disclosed in Japanese Utility Model Laid-Open No. 4-137115, a cubic that can increase rigidity even with a member having a small cross section has been developed. That is, when the mullions, as shown in FIG. 1 4, providing a curtain wall 93 into the opening portion of the atrium 92 from 1 floor 90 to 3 floors 91, that panel 9
4 is used as a cubic 95 for supporting the support 4. still,
The cubic 95 is disposed inside the panel 94 and is not exposed to the outside. Thereby, especially when the panel 94 is a glass sash or the like, the appearance can be improved.
The cubic 95 is an outdoor vertical member 96 made of an extruded aluminum member.
A truss structure in which aluminum lattice members 98 are obliquely connected between the indoor vertical members 97 is fixed to the first floor 90 and the third floor 91 at the upper and lower ends of the outdoor vertical members 96. According to such a cubic 95, even if each of the vertical members 96 and 97 is formed of an extruded aluminum member having a small cross section, the rigidity of the cubic 95 can be increased by adding a lattice member 98 to form a truss structure. At the same time, the use of a member having a small cross section can reduce the occupied space and improve the appearance.

[0005] However, there are cases where the opening for attaching the curtain wall is relatively small, that is, there is a case where the rigidity of the cubic 95 is not necessary, and the occupied space can be made smaller than that of the cubic 95 or the conventional H-shaped steel. Was required. In addition to the structure of the curtain wall, not only the pillars and beams of the building, but also the structural members such as the pillars and beams of the gantry for displaying products such as the curtain wall have a small cross-section and a necessary and sufficient rigidity. A member was required.

An object of the present invention is to provide a structural member which can reduce the occupied space with a small cross section and can obtain relatively high rigidity as compared with its cross sectional area.

[0007]

Means for Solving the Problems] structural member of the present invention, the intermediate portion of the elongated main structural material, at least one intermediate portion
A side reinforcing plate, and both ends of the main structural member
End side reinforcement smaller than the intermediate part side reinforcement plate
A tension plate is provided for each plate between the intermediate portion side reinforcing plate and the end portion side reinforcing plate at the end of the main structural material, or between each intermediate portion side reinforcing plate. Times
It is constructed so as to be freely movable .

In this case, it is preferable that the tension member is provided so that its tension can be adjusted. In addition, the structural member includes a plate for reinforcing the intermediate portion and a plate for reinforcing the end portion.

When both side reinforcement plates are provided, they include both tension members that are stretched between the intermediate portion side reinforcement plates.
But not good. Further, the intermediate side reinforcing plate and the end portion
The side reinforcing plate may project from only one side of the main structural member, or may project from both sides of the main structural member.

[0009]

In such a structural member of the present invention, an intermediate-side reinforcing plate and an end- side reinforcing plate projecting from a main structural member are provided.
Intermediate with two or more protruding parts between heavy duty plates or main structural material
A tension member is stretched between the part-side reinforcing plates. By stretching this tension material with an appropriate tension, the main structural material is appropriately compressed and the rigidity is improved, and the main structural material is expanded in the direction in which the tension material extends, that is, in the direction opposite to the side on which the tension material is provided. Even if a force is applied so that the structural material is bent, the force can be canceled by the tensile force of the tension material, and the main structural material is prevented from being bent. For this reason, the rigidity of the structural member of the present invention is improved as compared with the structural member composed of only the main structural member, and the structural member can have necessary and sufficient rigidity even if a member having a small cross section is used as the main structural member. Further, if the tension of the tension member is adjusted, the rigidity of the structural member is also adjusted, and the optimal rigidity according to the use of the structural member can be set.

For this reason, if the structural member 1 of the present embodiment is used as a curtain for the curtain wall 2, the space occupied by the curtain wall 2 is small.
When a glass sash is provided so that the interior and exterior can be seen, the view is hardly obstructed by the orientation, and a building with good visibility can be obtained.

Since the structural member 1 is composed of the main structural member 5 or the like having a small cross section, even if it is exposed in a room or the like, the design of the room can be improved without deteriorating the design of the room. . The structural member 1 is composed of a main structural member 5 having a small cross section.
Is used, since the tension member 6 is stretched and reinforced, the rigidity of the entire structural member 1 can be increased as compared with the cross-sectional area thereof. Therefore, the structural member 1 is made up of the conventional cubic 9
When the rigidity of about 5 is not necessary, for example,
It can be sufficiently used as a post when a curtain wall is installed for each general floor, not for the second floor.

The end-side reinforcing plate 8 is formed smaller than the intermediate-side reinforcing plate 7, and at both upper and lower ends of the main structural member 5, the tension member 6 is configured to approach the main structural member 5. ing. For this reason, at the time of connecting the pin plates 25 at the upper and lower ends of the main structural member 5 to the pin plates 26 on the floor and the ceiling, the reinforcing plate 8 and the tension member 6 are connected.
Does not hinder the work, and the work of installing the structural member 1 can be easily performed. Also, the structural member 1 is made of aluminum main structural material 5 and the like, and is lightweight, and is attached to a floor of a building by pin bonding.
Can be easily moved and attached, and the workability at the time of installation can be further improved.

Furthermore, since the intermediate portion side reinforcing plate 7 is formed in a substantially H-shape in a plane, the transmission of the force applied by the tension members 6 becomes smooth, and the mounting work of each tension member 6 can be performed easily and simultaneously. It is possible to make the plate 7 excellent in design.

FIG. 7 shows a structural member 30 according to a second embodiment of the present invention. The structural member 30 is the same as the structural member 1 of the first embodiment in that the structural member 30 is used as a support for supporting the panel 3 of the curtain wall 2. However, in the structural member 1, the reinforcing plates 7 and 8 protrude on both sides of the main structural member 5, and the tension members 6 are stretched between the plates 7 and 8. The structural member 30 has an intermediate-side reinforcing plate 33 and an end-side reinforcing plate 34 protruding only on one side of the main structural member 31.

Since the tension member 32, the intermediate-side reinforcing plate 33, and the end-side reinforcing plate 34 are provided only on one side of the main structural member 31, the indoor and outdoor surfaces of the curtain wall panel 3 are provided as shown in FIG. The tension member 32 and the like can be provided in a direction perpendicular to the direction. For this reason, in particular, the force for bending the main structural member 31 in the outdoor direction, that is, the force for the curtain wall 2 to fall down to the outdoor side is the structural member 30.
Can be canceled by the tension of the tension member 32, so that the structural member 30 suitable for preventing the curtain wall 2 from falling down can be obtained. Further, since the tension member 32 and the plates 33 and 34 are provided only on one side of the main structural member 31, the occupied space and the like can be further reduced as compared with the first embodiment, and the obstruction of the visual field can be reduced. There is also an effect that it can be reduced.

It is composed of an intermediate side reinforcing plate 47 and an end side reinforcing plate 48. On the other hand, as shown in FIG. 9, the lower frame 42 has a tension member 51, an intermediate portion side reinforcing plate 52 and an end portion only on one side of the main structural member 50, similarly to the structural member 30 of the second embodiment. Part side reinforcement plate 5
3 are provided. In addition, reinforcing plate 5
2 is provided only at an intermediate position where the main structural member 50 is bisected in the longitudinal direction. The upper frame 43 is made of a substantially cylindrical aluminum extrusion, like the main structural member 50 of the lower frame 42.

In this embodiment as well, since the columns 41 and the frame 42 of the building material mounting base 40 are composed of the main structural members 45 and 50 having a small cross section, the exclusive space is reduced and exhibited. There is no effect that the sash 44 and the like are covered and hidden by the columns 41 and the frame 42, and the display state is not damaged. Further, since the lower frame 42 to which the load of the sash 44 is applied and the supporting column 41 for supporting the gantry 40 are reinforced by the tension members 46 and 51, the main structural members 45 and 50 are formed by extruding a small-section aluminum extrusion member or the like.
