Description

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 panel with a frame is attached to a strut material of a truss body, such as a roof or a wall of the truss body.

[0002]

2. Description of the Related Art FIG. 1 shows an example of a conventional truss body 1 and shows a part thereof. The truss body 1 includes a plurality of strut members 2
(Vertical 2a, horizontal 2b, connection 2c) is formed by repeating a structure in which one end is connected to one hub 3, but is often used as a roof, a wall surface, or a floor surface of two or more floors. At this time, the panel 4 is often attached to the truss body 1. Examples of the panel 4 include a flat floor material, a roof material, a glass plate and the like (referred to as a flat panel) and a framed panel in which these are fitted to a frame (such as a sash fitted with a glass plate). The flat panel and the framed panel are collectively referred to as a panel.

[0003] 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 therein, and the pressing edge 6 is applied to the auxiliary member 5 from the surface side of the panel 4 and fixed. At this time, the auxiliary member 5 is attached using the truss body 1 and the coupling metal member 7, but the coupling metal member 7 is often mounted so as to protrude from the hub 3, and only the both ends of the auxiliary material member 5 are supported, and the intermediate part has a surface. The state is raised from the truss structure 1. Therefore, there are the following difficulties. It is necessary that the auxiliary member 5 has a high bending strength capable of withstanding the load and wind pressure of the panel, and a large cross-sectional dimension and wall thickness are used, so that the cost increases and the weight of the entire truss structure increases. are doing.

When the truss structure to which the panel 4 is attached is completed, a gap is provided between the surface continuously formed by the panel 4 and the surface formed by the surface truss structure 1 (the surface of the surface truss structure 1). In a place where the back side (indoor side) of the surface truss structure 1 can be seen due to the occurrence of the above, there is a drawback that the surface structure looks double and the appearance is not clear in some cases. When the truss structure to which the panel is attached is used as a floor, there is a gap between the surface continuously formed by the panel 4 and the surface formed by the truss body 1, so that the panel is likely to vibrate and noise such as footsteps is generated. Easy to emit. Requires a large number of metal fittings 7,
In addition, a great deal of labor is required to install this, which also increases costs.

Japanese Patent Application Laid-Open No. Hei 7-102640 discloses that a frame member (corresponding to a strut member 2 of a truss structure) is provided with a jacket supporting member (an auxiliary member thereof) in order to reduce the total weight and the total cost. 5 and 9 are proposed. However, as shown in the examples of FIGS. 5 and 9, if the jacket support member is provided directly on the frame member, the jacket material (panel 4) for the frame member is not provided. It is necessary to prepare a different frame member every time the mounting angle changes). Also, as shown in FIG. 10 and FIG. Between the surface continuously formed and the surface of the truss structure,
You will have the same difficulties as before. Further, this publication discloses how to solve such difficulties when the strut material 2 forming the truss body 1 is a cylinder or the hub 3 has a curved surface, such as a spherical surface, where the auxiliary material 5 is attached. There is no disclosure of what to do.

[0006]

The present invention does not require a specially high-strength auxiliary member for attaching a panel, and does not use a fitting for connecting the auxiliary member and the truss body. Another object of the present invention is to provide a truss structure having a structure in which there is no space between the auxiliary material and the truss body.

[0007]

SUMMARY OF THE INVENTION A truss body is formed by repeating a structure in which struts having a substantially circular cross section are joined by a hub. The strut member has, on its outer peripheral surface, mounting receiving portions provided at intervals in a cross section and a contact receiving portion located therebetween. The strut material is often made of an extruded product of an aluminum alloy or a synthetic resin. In this case, the mounting receiving portion is continuous in the longitudinal direction of the strut material. In the case of a flat panel, it is attached to a truss body using an auxiliary material, and in the case of a panel with a frame, it is directly attached to the truss body using a frame material constituting this frame. In the case of a panel with a frame, the frame material attached to the strut material of the truss body,
The same structure as the auxiliary material in the case of a flat panel is provided.

The auxiliary material is for attaching the panel to the strut material, and the strut material side is formed so as to swallow the arc-shaped outer peripheral portion of the strut material. And a contact portion located therebetween. The auxiliary member has, for example, a U-shape having a connecting portion and legs on both sides thereof in cross section. The auxiliary member is in contact with the outer peripheral portion of the strut material at the connecting portion, and an attachment portion is provided at the tip of the leg on both sides. The portion of the connecting portion in contact with the outer peripheral portion of the strut material is the contact portion, and the portion of the strut material in contact with the connecting portion is the contact receiving portion. The attachment portion may correspond to the attachment receiving portion of the strut material, and may have a structure for attaching the auxiliary material to the strut material. That is, the auxiliary material is fitted to the strut material by sliding in the axial direction of the strut material, or the auxiliary material is fitted from above the strut material and attached by inserting the legs. In any case, the abutting part of the auxiliary material is applied to the abutment receiving part of the strut material, and the mounting part is attached to the mounting receiving part so that the auxiliary material swallows the arc-shaped outer peripheral part of the strut material. Is attached to the strut material

The auxiliary material is also often an extruded material of an aluminum alloy or a synthetic resin, and the attachment portion is preferably of a structure that can be integrally molded. However, another molding method may be used. In some cases, a molded product is attached. It should be noted that conventional fittings are not required to attach the auxiliary material to the strut material. Since the auxiliary member comes into contact with the outer peripheral portion of the strut member, the gap generated between the surface formed by the series of panels attached to the auxiliary member and the truss body surface can be reduced or eliminated. Also,
Since the load applied to the auxiliary member is uniformly supported in the longitudinal direction of the auxiliary member, a high-strength member is not required unlike the case where only both ends are supported. Further, since the connecting portion is in contact with the strut material over the entire length of the auxiliary material, the vibration of the panel is absorbed by the truss body, and the generation of noise is reduced.

[0010] The auxiliary member has legs extending along the outer periphery of the strut member on both sides of a portion in contact with the strut member,
In some cases, a mounting portion is provided at the tip of the leg portion, and the leg portions on both sides abut on the outer peripheral portion of the strut material. With this structure, the degree of adhesion between the auxiliary member and the strut member can be increased, the attachment state of the auxiliary member to the strut member can be stably maintained, and the mounting angles of the panels located on both sides of the strut member are not flat. In such a case, the space between the strut member and the strut member can be minimized. The panel may be attached to the truss body by overlapping the hub at the hub and connecting the panels on both sides continuously. With this structure, the surface formed on the truss body can be finished to a beautiful appearance with little unevenness and discontinuity, for example, by making panels located on both sides of the hub continuous flat at the hub. The fact that the cross section of the strut material is substantially circular is intended to be an elliptical or polygonal cross section of a pentagon or more.

[0011]

FIG. 1 shows a part of a truss structure 8, which is used for a roof by using a flat panel 4a. The truss structure 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 material 2a, an upper horizontal strut material 2b, and a lower vertical strut material 2
d, lower horizontal strut material 2e and connecting strut material 2c
The structure in which one end of the above (collectively referred to as strut materials 2) is connected to one hub 3 is repeatedly formed on a large surface. The hub 3 is spherical, and the struts 2a to 2
e is a cylindrical shape having a circular cross section, and is based on an extruded material of an aluminum alloy. The strut members 2a to 2e are attached to the hub 3 by screwing the ends. In this embodiment, the surface of the hub 3 including the top surface of the upper vertical strut material 2a and the top surface of the upper horizontal strut material 2b, that is, the portion protruding from the surface of the truss body 1 is cut off, and the panel mounting portion 3a ( (Planar part).
The upper strut member 2a and the upper horizontal strut member 2b have attachment receiving portions 9 on the outer surfaces on both sides of the diameter in cross section, that is, on the outer peripheral portions of the strut members 2a and 2b.
The mounting receiving portion 9 is in the form of a flanged projection corresponding to the dovetail groove.

The panel 4 is made of a flat plate material 10 (FIGS. 1 to 5) formed by extruding a rectangular hollow aluminum alloy and having a cover material 11 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 interval between the horizontal strut members 2b, and the horizontal dimension (width) is about 1/6 of the interval formed by the vertical strut members 2a. On the longitudinal end face 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 joints between adjacent panels 4.

The auxiliary material 5 (FIG. 5) is an extruded material of an aluminum alloy, and has a generally U-shaped cross section including a connecting portion 15 and legs 16a and 16b on both sides thereof in cross section. , 16b are provided with mounting portions 17 having a dovetail cross section. The auxiliary member 5 constitutes a fixed base 18 by projecting upward at the center of the connecting portion 15.
The auxiliary member 5 is arranged vertically and horizontally along the upper vertical strut member 2a and the upper horizontal strut member 2b. At the hub 3, the upper vertical strut member is used vertically so as to make the 2a continuous. However, the legs 16a, 16b on both sides of the connecting portion 15
The end is removed according to the diameter of the hub 3 so as not to interfere with the spherical hub 3.

In order to construct the roof, first, the strut members 2 are connected 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. Keep it. The two 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.
The fitting can be easily performed only by fitting the mounting portion 17 of the strut 16b and sliding in the axial direction from the end of the strut material. Also,
Since the auxiliary member 5 has a substantially U-shaped cross section, the arcuate outer peripheral portion of the strut member 2a is swallowed between the leg portions 16 on both sides, and the connecting portion 15 is brought into contact with the outer peripheral surface of the strut member 2a. By attaching the mounting portion 17 to the mounting receiving portion 9 of the strut material 2a, the auxiliary material 5 can be mounted on the strut material 2a. That is, the contact portion 15a of the auxiliary member 5
Is mounted in contact with the contact receiving portion 15b of the strut material 2a (FIG. 5). Furthermore, since the legs 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 stabilized. Therefore, the position does not shift during the assembly operation. At the location of the hub 3, auxiliary members 5 longer than the strut members are attached to the upper vertical strut members 2a on both sides, and the ends of the auxiliary members 5 are abutted by the panel mounting portion 3a on the upper surface of the hub 3. An end of the auxiliary member 5 mounted on the upper horizontal strut member 2b is applied to a side surface of the auxiliary member 5 in a vertical direction at an upper portion of the hub 3.

Next, two auxiliary members 5 which are vertically spaced from each other are supported at both ends of the panel 4, and the connecting fins 12a and 12b at the longitudinal ends are overlapped to fix the auxiliary member 5 to a pedestal. Attach it to 18. In addition, adjacent panels 4 are connected by mutually engaging connection fins 14a and 14b provided on the side surfaces. In addition, since the side surface of the panel 4 in contact with the two auxiliary members 5 spaced apart in the lateral direction is not provided with an equivalent to a connecting fin, the auxiliary member 19 (FIG. 2) is used to assist the auxiliary member. The material 5 is fixed to the fixing base 18. Then, the sealing material 2 is applied to the joint generated between the vertical and horizontal panels.
Fill with 0 to complete.

This roof structure is configured such that the auxiliary member 5 is almost 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. Distributed and supported. Also,
There is almost no space between the surface formed by the continuous panel 4 and the surface of the truss body 1. Furthermore, since the upper surface of the hub 3 is formed as a flat portion so as not to 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 panel with a frame (a 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 member 21a and an edge member 21b, both of which are extruded products of an aluminum alloy, and the base member 21a is an auxiliary member in the first embodiment. 5 has substantially the same configuration. Therefore, the base 21a and the strut member 2a are attached by abutting the contact portion 15a on the contact receiving portion 15b. Common parts are denoted by the same reference numerals, and description thereof is omitted. The glass plate 20 is a strut material 2
are mounted on both sides of the base 21a attached to the base 21a using cushions, and are fixed on the butted edges by a pressing edge 21b attached to the fixed base 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
Unlike the case in which a requires the auxiliary member 5 for attachment, the frame member 21 can be used to directly attach to the strut member 2a.

FIG. 7 shows a third embodiment, in which a flat panel 4a and a framed panel 4b of a sash fitted with glass are attached to a strut member 2a using an auxiliary member 5 so as to abut each other. In this case, the flat panel 4a is attached to the fixed base 18 of the auxiliary member 5 by the connecting fins 12 of the end member 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 base 18. It is 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 shape of the end member 13 or the frame member 21, one panel can be attached to the other. Can be mounted at an angle. FIG. 8 shows a fourth embodiment, in which framed panel bodies 4b are attached to both sides of strut material 2a at an angle. Base 2 of frame material 21
1a, the leg portions 16a, 16b on both sides of the connecting portion 15 are formed at an angle along the cross-sectional shape of the upper longitudinal strut material 2a in accordance with the angle of the glass plate 20, and the strut material 2a Swallow the arc-shaped outer periphery,
The contact portion 15a is in contact with the contact receiving portion 15b. At the distal ends of the legs 16a and 16b on both sides, there are mounting portions 17 at positions corresponding to the mounting receiving portions 9 provided on the outer peripheral portion of the upper vertical strut material 2a. Since the legs 16a and 16b are configured to conform to the cross-sectional shape of the strut material 2a, the base 21a includes the legs 16a and 16b in addition to the contact portion 15a.
The portion 16b can be brought into contact with the outer peripheral portion of the strut material 2a. The glass plates 20 on both sides are
By attaching to the fixing pedestal 18 the pressing edge member 21b formed at the same angle as the above, it is fixed all at once. The base 21a and the pressing body 21b are part of a sash frame for mounting the glass plate 20.

In this embodiment, the connecting portion 15
And the legs 16a and 16b on both sides are made to contact the outer peripheral portion of the upper vertical strut member 2a.
1 is easy to stabilize, and the contact area with the upper vertical strut member 2a is increased.
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 the same as the fourth embodiment, except that the framed panel body 4b is mounted flat on both sides of the strut material 2a so as to form the same plane. The base 21a of the frame member 21 has legs 16a and 16b formed on both sides of the connecting portion 15 at an angle along the cross-sectional shape of the upper longitudinal strut member 2a. , A support portion 24 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 material 2a. With this configuration, the frame member 21 swallows the arc-shaped outer peripheral portion of the strut member 2a and is attached to the strut member 2a.
The glass plates 20 on both sides are mounted on the same surface. Also,
The frame member 21 includes a connecting portion 15 and legs 16a and 16b, as in the fourth embodiment.
Since the base members 21a and 16b conform to the cross-sectional shape of the strut member 2a, the base 21a
In addition, the strut material 2 is also used in the legs 16a and 16b.
a can be brought into contact with the outer peripheral portion of the strut member 2a, and the attachment state of the frame member 21 to the strut member 2a is stabilized. FIG.
Numeral 0 indicates the sixth embodiment, which is characterized by the form of the panel mounting portion 3a in the hub 3. In this embodiment, the mounting surface of the hub 3 which is a sphere is flat on the top surface, and the side surface along the longitudinal direction of the upper vertical strut material 2a is the same as the hanging angle of the legs 16a, 16b of the auxiliary material 5 or the base 21a. It is cut and formed on 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 without being lifted at the hub 3, and the auxiliary member 5 of the upper horizontal strut member 2b is attached. The end of the panel 4 can be attached to the auxiliary member 5 of the upper vertical strut member 2a by abutting the leg 16a, 16b (side surface), and the panel 4 can be attached close to the truss body 1. Also, the hub 3 is provided on the surface formed by the panel 4.
A flat surface can be formed without generating a convex portion or interrupting the surface at the position.

FIG. 11 shows a seventh embodiment, which is characterized by the structure of the mounting receiving portion 9 provided on the upper vertical strut material 2a and the upper horizontal strut material 2b and the mounting portion 17 provided on the auxiliary material 5. That is, the attachment receiving portion 9 is in the form of a fin protruding upward from the outer peripheral portion of the strut material 2a, and the attaching portion 17 is fitted from above in the form of an engaging fin capable of preventing lateral movement. 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 be moved 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 place. There is an advantage to be attached.

The case where the truss structure having the panels attached thereto is used for the roof has been described above, but this structure can also be applied to the construction of a wall surface or a floor surface. The truss body is not limited to a plane. The auxiliary material 5 may have a structure in which at least the side in contact with the strut material swallows the arc-shaped outer peripheral portion of the strut material, and the contact portion 15a on the auxiliary material 5 side contacts the contact receiving portion 15b on the strut material 2 side. However, the present invention is not limited to a specific form. Further, the hub is not limited to a spherical shape.

[0021]

According to the structure of the first aspect, there is almost no space between the surface formed by the continuous panel and the surface of the truss body, so that the appearance when viewed from the back side is hardly impaired. Since the load received by the auxiliary material can be transmitted uniformly to the truss body over the entire length of the auxiliary material by the contact part and the contact receiving part, there is no need to design the strength of the auxiliary material high,
The cost can be reduced, and the weight of the entire truss structure can be reduced. Since the auxiliary material for attaching the panel is in contact with the strut material of the truss body, the panel is less likely to vibrate, and less noise is generated even when the truss structure to which the panel is attached is used for the floor. The auxiliary member is attached to the strut member in such a manner as to swallow the arc-shaped outer peripheral portion of the strut member, so that the mounting state is stable.

According to the second aspect of the present invention, since the frame member on the side of the framed panel body to be attached to the strut member can be directly attached to the strut member and stabilized, the attaching work is quick and the separate body is provided. No auxiliary materials are required. In the mounting structure of the truss body and the panel, the portion corresponding to the auxiliary material does not overlap, so that the total weight of the truss structure can be reduced. According to the configuration of the third aspect, the connecting portion that comes into contact with the strut member supports the load received by the base of the auxiliary member or the frame member, and the legs on both sides thereof are attached to the strut member. Can be stably mounted in a balanced manner. According to the configuration of the fourth aspect, there are many contact points between the auxiliary member and the strut member, and the load applied to the auxiliary member can be more widely dispersed. Further, in the cross section, not only the connecting portion at the center but also the legs on both sides thereof come into contact with the strut material, so that the attachment state of the auxiliary material is further stabilized. According to the configuration of the fifth aspect, a truss structure having a flat surface without any protrusion by the hub can be obtained.
