Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a truss structure in which a flat panel or a framed panel is attached to a truss member of a truss body, such as a roof or a wall surface of a truss body.

[0002]

2. Description of the Related Art FIG . 12 shows an example of a conventional truss body 1,
Shows some. In the truss body 1, one end of a plurality of strut members 2 (length 2a, width 2b, connection 2c) is connected to one hub 3
Although it is repeatedly formed with the structure for connecting to, it is often used as a roof, a wall surface, or a floor above the second floor, and at that time, the panel 4 is often attached to the truss body 1. The panel 4 may be a flat floor material, a roof material, a glass plate, or the like (referred to as a flat panel), or a panel with a frame (a sash or the like having a glass plate fitted) fitted with a frame. The flat panel and the framed panel are collectively referred to as a panel.

The panel 4 is usually provided separately from the truss body 1,
The auxiliary member 5 is connected to the truss body 1 and fitted into the truss member 1, and the pushing edge 6 is fixed to the auxiliary member 5 from the front surface side of the panel 4. At this time, the auxiliary member 5 is attached using the truss body 1 and the connecting metal fitting 7, but the connecting metal fitting 7 is often attached to the hub 3 so as to project, and the auxiliary material 5 is supported only at both ends and the middle portion is a surface. The truss structure 1 is lifted up. Therefore, there are the following drawbacks. It is necessary to make the auxiliary member 5 high in bending strength capable of withstanding the load and wind pressure of the panel. Since the auxiliary member 5 having a large cross-sectional dimension and wall thickness is used, the cost is increased and the weight of the truss structure as a whole is increased. is doing.

When the truss structure having the panel 4 attached thereto is completed, a space is provided between the surface continuously formed by the panels 4 and the surface formed by the surface truss structure 1 (the surface of the surface truss structure 1). However, in a place where the back side (indoor side) of the surface truss structure 1 can be seen, the surface structure looks double, and in some cases, the appearance is not neat. When the truss structure with the panel attached is used as the floor surface, there is a gap between the surface formed by the panel 4 and the surface formed by the truss body 1, so that the panel easily vibrates and makes noise such as footsteps. Easy to emit. Requires a large number of fittings 7,
Also, a great deal of labor is required to mount this, which also increases the cost.

Japanese Unexamined Patent Publication (Kokai) No. 7-102640 discloses a frame member (corresponding to a strut member 2 of a truss structure) for a frame member (here, an auxiliary member) in order to reduce the total weight and the total cost. 5 has been proposed, but a structure corresponding to FIGS. 5 and 9 is proposed.
Can, directly to the frame member, and providing a jacket supporting member
However , in this case, it is necessary to prepare a different frame member each time the mounting angle of the outer covering material (corresponding to the panel 4) with respect to the frame member changes, and FIGS.
When the structure corresponding to the above is adopted, the covering material supporting portion constituting member is separately used, but this also causes a gap between the surface continuously formed by the panel and the surface of the truss structure. , Will have the same drawbacks as before. Furthermore, this publication discloses how to solve such a difficulty when the strut member 2 forming the truss body 1 is a cylinder or the hub 3 is a spherical member or the like to which the auxiliary member 5 is attached. It does not disclose what to do at all.

[0006]

SUMMARY OF THE INVENTION The present invention does not require a specially strong auxiliary material for attaching a panel, and does not use a metal fitting for connecting the auxiliary material and the truss body. An object of the present invention is to provide a truss structure having a structure in which there is no space between the auxiliary member and the truss body.

[0007]

A truss body is constructed by repeating a structure in which strut members having a substantially circular cross section are connected by a hub. The strut member has, on the outer peripheral surface, mounting receiving portions provided at intervals in the circumferential direction of the cross section and a contact receiving portion located therebetween. Strut materials are often extruded products of aluminum alloy or synthetic resin,
In this case, the attachment receiving portion is continuous in the longitudinal direction of the strut material. In the case of a flat panel, it is attached to the truss body using an auxiliary material, and in the case of a panel with a frame, it is attached directly to the truss body using the frame material that constitutes this frame. In the case of a panel with a frame, the frame material attached to the strut material of the truss body is provided with the same structure as the auxiliary material in the case of a flat panel.

The auxiliary material is for attaching the panel to the strut material and extends over substantially the entire length of the strut material.
It has a length, and in the cross section, the strut material side is formed into a shape that swallows the arc-shaped outer peripheral portion of the strut material, and the mounting portion provided at a distance to this swallowing portion and the contact portion located between them. have. Auxiliary material is a C-shape having a leg portion and on both sides connecting portions at cross section, in contact with the outer peripheral portion of the strut member by the connecting portion, provided with a mounting portion to the leg tip portions on both sides. The portion of the connecting portion that contacts the outer peripheral portion of the strut material is the contact portion, and the portion of the strut material that contacts the connecting portion serves as the contact receiving portion. The attachment portion may have a structure corresponding to the attachment receiving portion of the strut material and for attaching the auxiliary material to the strut material. That is, the auxiliary member is slidably mounted on the strut member by sliding it in the axial direction of the strut member, or the auxiliary member is fitted by being fitted from above the strut member and then the leg portion is inserted. In any case, the contact portion of the auxiliary material is applied to the contact receiving portion of the strut material, and the mounting portion is attached to the mounting receiving portion so that the auxiliary material swallows the arc-shaped outer peripheral portion of the strut material. Is attached to the strut material.

The auxiliary material is also often an extruded material of aluminum alloy or synthetic resin, and it is preferable that the mounting portion has a structure in which it can be integrally molded, but other molding methods may be used. A molded product may be attached. It should be noted that conventional fittings are not required to attach the auxiliary material to the strut material. Since the auxiliary member is in contact with the outer peripheral portion of the strut member, the gap between the surface formed by the series of panels attached to the auxiliary member and the surface of the truss body can be reduced or eliminated. Also,
Since the load applied to the auxiliary material is uniformly supported in the longitudinal direction of the auxiliary material, it is not necessary to have high strength as in the case where only both ends are supported. Further, since the connecting portion is in contact with the strut member over the entire length of the auxiliary member, the vibration of the panel is absorbed by the truss member and the noise is reduced.

The auxiliary member is provided with legs extending along the outer periphery of the strut member on both sides of the portion in contact with the strut member,
A mounting portion may be provided at the tip of the leg portion, and the leg portions on both sides may be in contact with the outer peripheral portion of the strut member. With this structure, the degree of adhesion between the auxiliary material and the strut material can be increased, the attachment state of the auxiliary material to the strut material can be stably maintained, and the mounting angles of the panels located on both sides of the strut material are not flat. In this case, the strut members can be attached with a minimum distance. The panel may be attached to the truss body in such a manner that the panel overlaps with the hub at the hub and the panels on both sides are continuous. With this structure, the panels located on both sides of the hub can be made flat and continuous even at the hub, so that the surface formed on the truss body can be finished with a clean appearance with less irregularities or interruptions. The fact that the strut material has a substantially circular cross section is intended to have an elliptical shape or a polygonal cross section of pentagon or more.

1 is a part of a truss structure 8 and is used for a roof by using a flat panel 4a. The truss structure body 8 includes the truss body 1, the panel 4 and the auxiliary member 5 (FIG. 2). The truss body 1 includes an upper vertical strut member 2a, an upper horizontal strut member 2b, and a lower vertical strut member 2
d, lower lateral strut member 2e and connecting strut member 2c
The structure in which one end of (the strut member 2 is generically referred to above) is connected to one hub 3 is repeated to form a large surface. The hub 3 is spherical, and the strut members 2a-2
Each of e is a cylinder having a circular cross section, and has an aluminum alloy extruded material as a base material. The strut members 2a to 2e are attached to the hub 3 by screwing the ends thereof. In this embodiment, the hub 3 has a surface including the top surface of the upper vertical strut member 2a and the top surface of the upper horizontal strut member 2b, that is, a portion projecting from the surface of the truss body 1 is cut off so that the panel mounting portion 3a ( Plane part).
The upper vertical strut member 2a and the upper horizontal strut member 2b each have a mounting receiving portion 9 on the outer surface on both sides of the diameter in cross section, that is, on the outer peripheral portion of the strut members 2a and 2b. The mounting receiving portion 9 is in the form of a flanged protrusion corresponding to the dovetail groove.

The panel 4 has, as a base material, a flat plate material 10 (FIGS. 1 to 5) formed by extruding a rectangular hollow aluminum alloy, and a cover material 11 is attached to the surface thereof. Six pieces are used for one rectangle formed by the material 2a and the lateral strut material 2b. That is, the vertical dimension (length) of the panel 4 is substantially equal to the spacing between the horizontal strut members 2b, and the horizontal dimension (width) is about 1/6 of the spacing formed by the vertical strut members 2a. End material 1 provided with connecting fins 12 on the longitudinal end surface of the panel 4.
3 is screwed to close the space inside the panel.
The panel 4 also has connecting fins 14 on both sides in the vertical direction.
a, 14b, and these connecting fins 14a, 14b
Can be engaged with each other in the vertical direction to close the joint between the adjacent panels 4.

The auxiliary member 5 (FIG. 5) is the strut member 2a.
It is an extruded material of aluminum alloy having a length almost the same as the length of 2b, and has a U-shape as a whole with a connecting portion 15 and leg portions 16a and 16b on both sides in a cross section. A mounting portion 17 having a dovetail cross section is provided on each of 16a and 16b. Further, the auxiliary member 5 projects upward from the center of the connecting portion 15 to form a fixed pedestal 18. The auxiliary members 5 are arranged vertically and horizontally along the upper vertical strut members 2a and the upper horizontal strut members 2b, but at the hub 3, the upper vertical strut members 2a are used in a continuous manner. However, the legs 16 on both sides of the connecting portion 15
a and 16b are hubs 3 so as not to interfere with the spherical hub 3.
Remove the end according to the diameter of.

To construct the roof, first, the strut members 2 are joined by the hub 3 to assemble the truss body 1. At this time, the auxiliary members 5 are previously attached to the upper vertical strut members 2a and the upper horizontal strut members 2b. I'll do it. For mounting, both leg portions 16a of the auxiliary member 5 are attached to the mounting receiving portions 9 on both sides provided on the outer peripheral portions of the upper vertical strut member 2a and the upper horizontal strut member 2b.
This can be easily done by fitting the mounting portion 17 of 16b and sliding it axially from the end of the strut material. Also,
Since the auxiliary member 5 has a substantially U-shaped cross section, the arc-shaped outer peripheral portion of the strut member 2a is swallowed between the leg portions 16 on both sides to bring the connecting portion 15 into contact with the outer peripheral surface of the strut member 2a. The attachment member 17 can be attached to the attachment receiving portion 9 of the strut member 2a to attach the auxiliary member 5 to the strut member 2a. That is, the contact portion 15a of the auxiliary member 5
Is attached to the contact receiving portion 15b of the strut member 2a by abutting (FIG. 5). Further, since the leg portions 16a and 16b are attached to the strut member 2a so as to swallow (straddle) the arc-shaped outer peripheral portion of the strut member 2a, the attachment state is stable. Therefore, the position does not shift during the assembly work. At the hub 3, auxiliary materials 5 longer than the strut materials are attached to the upper and lower vertical strut materials 2a on both sides, and the end portions of the auxiliary materials 5 are butted to each other at the panel mounting portion 3a on the upper surface of the hub 3. The end portion of the auxiliary member 5 mounted on the upper lateral strut member 2b is abutted against the side surface of the auxiliary member 5 in the vertical direction at the upper portion of the hub 3.

Next, both ends of the panel 4 are supported by two auxiliary members 5 arranged at intervals in the vertical direction, and connecting fins 12a and 12b at the vertical end portions are overlapped with each other to fix the auxiliary member 5 on the pedestal. Attach to 18. Further, the adjacent panels 4 are connected by connecting the connection fins 14a and 14b provided on the side surfaces to each other. In addition, since the side surface of the panel 4 that contacts the two auxiliary members 5 arranged at intervals in the lateral direction does not include a part corresponding to a connecting fin, the auxiliary connecting metal fitting 19 (FIG. 2) is used to assist. The material 5 is fixed to the fixed base 18. Then, the sealing material 2 is applied to the joints generated between the vertical and horizontal panels.
Fill with 0 to complete.

This roof structure is constructed such that the auxiliary member 5 is in close contact with the upper vertical strut member 2a and the upper horizontal strut member 2b, and the load acting on the auxiliary member 5 is uniform over the entire length of the auxiliary member 5. It is dispersed and supported. Also,
There is almost no gap between the surface formed by the continuous panels 4 and the surface of the truss body 1. Furthermore, since the upper surface of the hub 3 is formed into a flat surface so that it does not protrude from the surface of the truss body 1, the panels 4 on both sides of the hub can be made flat and continuous. FIG. 6 shows a case of a panel with a frame (sash fitted with glass) 4b as a second embodiment. The glass plate 20 is fitted into the sash frame 22,
The frame member 21 is directly attached to the strut member 2a. In this embodiment, the frame member 21 attached to the strut member 2a is composed of a base body 21a and an ridge 21b, both of which are extruded products of an aluminum alloy, and the base body 21a is an auxiliary material in the first embodiment. 5 has substantially the same configuration. Therefore, the base body 21a and the strut member 2a are attached with the contact portion 15a in contact with the contact receiving portion 15b. The common parts are given the same reference numerals and the description thereof is omitted. Glass plate 20 is strut material 2
It is placed from both sides on the base body 21a attached to a using cushions, and is fixed on the abutted edges by a ridge 21b attached to the fixed pedestal 18 from above.
The base 21a has the same structure as the auxiliary member 5, but is a part of the sash frame 22, and the framed panel 4b is the flat panel 4
Unlike the case where a requires the auxiliary member 5 for attachment, the frame member 21 can be used to attach directly to the strut member 2a.

FIG. 7 shows a third embodiment in which the flat plate panel 4a and the framed panel 4b of the glass-fitted sash are attached to each other by using the auxiliary material 5 on the strut material 2a. In this case, the flat panel 4a is attached to the fixed pedestal 18 of the auxiliary member 5 by the connecting fins 12 of the end material 13, and the framed panel 4b fixes the connecting fins 23 provided on the frame member 21 of the sash frame 22 to the fixed pedestal 18. And attached. As described above, it is possible to attach different types of panels to the strut members 2a having the same cross-sectional shape, and by changing the shapes of the end members 13 and the frame member 21, one panel can be attached to the other. It is also possible to mount the panel at an angle. FIG. 8 shows a fourth embodiment, in which the framed panel body 4b is attached to both sides of the strut member 2a at an angle. Base material 2 of frame material 21
1a has leg portions 16a, 16b on both sides of the connecting portion 15 formed at an angle according to the angle of the glass plate 20 along the cross-sectional shape of the upper vertical strut member 2a. Swallow the arc-shaped outer periphery,
The contact portion 15a is in contact with the contact receiving portion 15b. At the tips of the leg portions 16a and 16b on both sides, a mounting portion 17 is provided at a position corresponding to the mounting receiving portion 9 provided on the outer peripheral portion of the upper vertical strut member 2a. Since the leg portions 16a and 16b are configured to follow the cross-sectional shape of the strut member 2a, the base body 21a includes the leg portion 16a, in addition to the contact portion 15a.
Even the portion 16b can be brought into contact with the outer peripheral portion of the strut member 2a. The glass plates 20 on both sides are auxiliary materials 5
The ridge 21b formed at the same angle as is attached to the fixed pedestal 18 to be fixed at once. The base 21a and the ridge 21b are a part of a sash frame for attaching the glass plate 20.

In this embodiment, the connecting portion 15
Since both the leg portions 16a and 16b on both sides are in contact with the outer peripheral portion of the upper vertical strut member 2a, the frame member 2
The mounting state of No. 1 is easily stabilized, and the contact area with the upper vertical strut member 2a is increased, so that the load acting on the base body 21a can be widely dispersed. The same applies to the structure of the auxiliary member 5 on the side in contact with the strut member 2a. FIG. 9 shows a fifth embodiment, which is similar to the fourth embodiment, except that the framed panel body 4b includes the strut member 2
It is flatly attached to both sides of a so as to form the same plane. The base member 21a of the frame member 21 has leg portions 16a and 16b formed on both sides of the connecting portion 15 at an angle along the cross-sectional shape of the upper vertical strut member 2a. The support portion 24 is provided in the middle portion. The mounting portion 17 corresponds to the mounting receiving portion 9 provided on the outer peripheral portion of the upper vertical strut member 2a. With this configuration, the frame member 21 is attached to the strut member 2a by swallowing the arc-shaped outer peripheral portion of the strut member 2a, while the glass plates 20 on both sides are attached to the same surface. Further, this frame member 21 is provided with the connecting portion 15 and the leg portions 16a and 16b, similarly to the case of the fourth embodiment.
Since the a and 16b are configured to follow the cross-sectional shape of the strut member 2a, the base 21a is the contact portion 15a of the connecting portion 15.
At the same time, the strut member 2 is also formed on the legs 16a and 16b.
It is possible to make contact with the outer peripheral portion of a, and the attachment state of the frame member 21 to the strut member 2a becomes stable. Figure 1
0 indicates the sixth embodiment, and is characterized by the shape of the panel attachment portion 3a of the hub 3. In this embodiment, the panel 3 mounting side of the hub 3 which is a sphere has a flat top surface, and the side surface along the longitudinal direction of the upper vertical strut member 2a is the same as the hanging angle of the auxiliary member 5 or the leg portions 16a and 16b of the base member 21a. It is formed by cutting it into an angled surface. According to this structure, the auxiliary member 5 of the auxiliary member 5 is attached to the upper vertical strut member 2a vertically through the hub 3 portion without floating at the hub 3 portion, and the auxiliary member 5 of the upper horizontal strut member 2b is attached. The end portions thereof can be attached by abutting against the leg portions 16a, 16b (side surface) of the auxiliary member 5 of the upper vertical strut member 2a, and the panel 4 can be attached close to the truss body 1. In addition, a flat surface can be formed without forming a convex portion at the hub 3 on the surface formed by the panel 4 or discontinuing the surface.

FIG. 11 shows a seventh embodiment, which is characterized by the structure of the mounting receiving portion 9 provided on the upper vertical strut member 2a and the upper horizontal strut member 2b and the mounting portion 17 provided on the auxiliary member 5. That is, the attachment receiving portion 9 is in the form of a fin projecting upward from the outer peripheral portion of the strut member 2a, and the attachment portion 17 is a fitting fin that fits into this from above and can prevent lateral movement. Therefore, the auxiliary member 5 can be attached so as to cover the strut member from above. The contact portion 15a of the auxiliary member 5 contacts the contact receiving portion 15b of the strut member 2a. Since the auxiliary member 5 can move upward with respect to the strut member 2a even after the attachment, it is necessary to fix the auxiliary member 5 to the strut member 2a at an appropriate position. It has the advantage of being installed.

Although the case where the truss structure with the panels is used for the roof has been described above, this structure can be applied to the construction of the wall surface or the floor surface. The truss body is not limited to a plane. At least the side of the auxiliary member 5 that comes into contact with the strut member is swallowed by the arc-shaped outer peripheral portion of the strut member, and the contact portion 15a on the auxiliary member 5 side is brought into contact with the contact receiving portion 15b on the strut member 2 side. It is not limited to a specific form. Further, the hub is not limited to the spherical shape.
