Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a panel unit such as a large span roof panel attached to a steel frame truss of a dome type roof and a floor panel provided between large beams in a general building.

[0002]

2. Description of the Related Art Recently, for indoor athletics facilities, etc.,
Large fixed dome roofs have been adopted. As the structure type of the fixed dome type roof, a structure in which a steel frame truss structure, a cable structure, and a combination of these steel frame truss structures and cable structures are known.

In such a dome type roof, if the steel frame truss has a large bending stress, the cross section of the steel frame becomes remarkably large, which is uneconomical. Further, in order to receive the weight of the roof finishing material such as a metal plate, it is necessary to keep the distance between the receiving materials within a certain range.

However, since it is uneconomical to dispose roof steel trusses finely, at present, generally, for example, as shown in FIG.
As shown in 1, steel frames 1, 1, 1, ...
Between each truss (steel frame joint (intersection) A, A, the area surrounded by A), a beam member or purlin material 2, 2, 2,
..., 3, 3, 3, ... are installed respectively. Then, in the meantime, as shown in FIG. 12, for example, the roof finishing material 4 is placed.

[0005]

However, in this case, the weight of the roof finishing material 4 is concentrated at an arbitrary position between the joints (intersection points) A of the steel truss through the beam members or the purlin material 2. Join. Therefore, a large bending stress due to a concentrated load is generated in the steel truss in addition to the bending stress caused by the deformation of the entire dome.

Further, since the bending stress resulting from the deformation of the entire dome is generally small, it is necessary to make the steel aggregate forming the truss extremely strong, which is uneconomical. Furthermore, it is uneconomical to attach a large number of beam members and purlin materials as in the conventional method in terms of materials and work, and since the work of mounting the work is performed at a high place, there is a risk. It was

Therefore, an object of the present invention is to cope with a large area in which the total load or most of the load of the roof panel can be directly transmitted to the intersection of the roof steel truss without the need for beam members and purlin materials. To provide a panel unit.

[0008]

In order to solve the above problems, the present invention provides a panel material, and a plurality of reinforcing materials radially extending from a substantially central portion on the back surface side of the panel material to a peripheral portion.
A bundle of which one end is connected in a substantially vertical arrangement at a portion where the reinforcing material intersects with the substantially central portion of the panel material, and the other end of the bundle and each of the radially extending tips of the reinforcing material. The panel unit is characterized in that the panel unit is provided between the two and has a plurality of cables that push up the intersections of the reinforcing members by the bundle material by the introduction of tension.

For example, the panel material has a polygonal shape, the reinforcing material is provided corresponding to each corner portion thereof, and the panel unit is joined to the body at each corner portion.

[0010]

[Function] On the rear surface side of the panel material, a radial cable is provided between the bundle material that is connected in a substantially vertical arrangement to the reinforcing material that extends radially from the substantially central portion and each tip of the reinforcing material. When the tension is introduced into, the intersection of the reinforcing members is pushed up by the axial force of the bundle arranged almost vertically. In other words, the tension of the cable pushes up the panel material through the bundle, and the center of the panel material is pushed up.
Since the bending stress of the reinforcing material is reduced, a light reinforcing material is sufficient.

Therefore, for example, like a panel material having a polygonal shape, each tip portion of the reinforcing material provided corresponding to each corner portion can be joined to the body. That is, for example, the total load of the roof panel or most of the load can be transferred directly to the intersection of the steel truss of the dome roof.

By previously making a panel unit composed of such a panel material, a reinforcing material, a bundle material and a cable, it is possible to quickly and easily perform a joining work at a few places on site.
For example, the roof can be finished, shortening the construction period and improving safety.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENT An embodiment of the panel unit according to the present invention will be described below with reference to FIGS.

First, FIG. 1 shows a roof panel as an example to which the present invention is applied.
Is a triangular roof panel 11 which is a panel material
And three reinforcements 12, 12, 12 radially provided on the back surface from the central portion to each corner, and three reinforcements 13, 13, 13 also provided along the peripheral portion of the back surface, One unillustrated steel frame bundle (strut) with its upper end connected to the intersection of the radial reinforcements 12, 12, 12 (the center of the roof panel 11) by vertical arrangement, and the lower end of the steel frame bundle And three radial reinforcing members 12, 12, 12 and the respective tip portions of the radial reinforcing members 12, and three cables (not shown) that are respectively installed by applying tension.

This panel unit 10 includes three truss joints (intersections) A, A, A formed by the steel frames 1, 1, 1, ... Which form the main frame of the dome type roof shown in FIG. It is provided with joints B, B, B. As shown in FIG. 2, each joint B is a suitable metal structure continuous from the aggregate of the reinforcing members 12, 13, 13 via the shaft member 14. The roof panel 11 is made of an appropriate material having waterproofness and weather resistance. Reinforcement 12,
As the 13 and the steel frame bundle material, narrow H-shaped steel or steel pipe is adopted. As the cable, a flexible cable having twisted steel wires that generate an appropriate tension or a reinforcing bar is used. In this embodiment, in order to directly transfer the entire load of the panel unit 10 to the steel truss joints (intersection points) A, A, A, the roof finishing material is received in the portion surrounded by the main truss shown in FIG. Although the reinforcing members 13, 13, 13 are provided in the peripheral portion of the above, if this is done, the reinforcing member becomes long and the bending stress of the reinforcing member itself increases, which is rather uneconomical.

Therefore, in the embodiment shown in FIGS. 3 to 5, the panel unit 3 having no reinforcement along the peripheral portion is used.
It is set to 0. That is, as shown in the figure, the panel unit 30 includes a roof panel 31 having a triangular shape, three radial reinforcements 32, 32, 32 on the rear surface thereof, and an intersection of the radial reinforcements 32, 32, 32. Department (roof panel 31
Between one steel frame bundle (strut) 35 whose upper ends are connected to each other by a vertical arrangement, and between the lower end of the steel frame bundle 35 and each tip of the radial reinforcing members 32, 32, 32. 3 cables 3 each installed with tension applied to
6, 36, and 36.

The panel unit 30 is, for example, as shown in FIG.
As shown in, inside the roof panel 31 joined and integrated by an appropriate connecting fitting 21 and the like, the lightweight channel steels 22 and 2 are provided.
Sound absorbing material 23, 2 such as glass wool through 2, 22 ,.
3, 23, ... And the radial reinforcement 3
An upper end portion of the steel frame bundle member 35 is rotatably attached to a bracket 37 provided at an intersection of 2, 32 and 32 by a pivot shaft 38. Further, the cables 36, 36, 36 are attached so as to pass through the lower end portion of the steel frame bundle material 35, and as shown by the arrows in FIG.
Tension is applied to 6, 36 and 36.

According to the panel unit 30, as shown in FIG. 5, the tension of the cables 36, 36, 36 causes the reinforcing members 32, 36 to pass through the steel frame bundles (struts) 35.
The intersection of 32 and 32, that is, the central portion of the roof panel 31, is pushed up, and as a result, the reinforcing members 32, 32, and 32.
The bending stress is reduced, and the reinforcing members 32, 32, 32 can be made light.

The joints B, B, B of the panel unit 30 are directly connected to the joints (intersections) A, A, A of the steel truss of the dome type roof shown in FIG.
The entire load of the panel unit 30 including the roof panel 31 or most of the load can be transmitted. That is, since the beam member and the purlin material, which have been conventionally required, can be eliminated, it becomes economical.

Since the roof panel 31, the reinforcing members 32, 32, 32, the steel bundle member (struts) 35, and the cables 36, 36, 36 are the panel unit 30 assembled in advance, their three joints B, By joining B and B to the steel truss joints (intersection points) A, A, and A, respectively, you can quickly finish the dome type roof by joining work at a few places on the site, shortening the construction period and improving safety. Can greatly contribute to

In the above embodiment, the panel units 10 and 30 are formed by the triangular roof panels 11 and 31 corresponding to the steel truss, but the shape surrounded by the main truss is not limited to the triangle and can be similarly applied.

That is, for example, as shown in FIG.
4 radial reinforcements 4 on a rectangular roof panel 41
2, 42, 42, 42 are provided, and like the above embodiment,
The panel unit 40 provided with a steel frame bundle (struts) and four cables may be used. Also, for example, in FIG.
As shown in (b), the pentagonal roof panel 51 has 5
It is also possible to provide a plurality of radial reinforcing members 52, 52, 52, 52, 52 to form a panel unit 50 provided with a steel bundle material (struts) and five cables as in the above-described embodiment.

Further, when the panel is large, it may be adjusted according to the magnitude of the tension of the cable as in the above embodiment, and a reinforcing material may be further provided. That is, for example, as shown in FIG. 8, three radial reinforcing members 82, 82, 82 are provided on a triangular roof panel 81, and the steel bundle member (strut) and three radial reinforcing members 82, 82, 82 are provided in the same manner as in the above embodiment. A panel unit 80 may be provided in which, after the cable is provided, three reinforcing members 89, 89, 89 are further provided so as to be bridged between the respective intermediate portions of the radial reinforcing members 82, 82, 82.

In each of the above embodiments, the present invention is applied to the roof panel attached to the steel frame truss of the dome type roof.
For example, the present invention can be applied to a floor panel provided between girders in a general building.

That is, as shown in FIGS. 9 and 10, four pillars 101, 101, 10 arranged with a large span.
Girder 102, 102, 102, 102 by 1, 101
In between, four radial reinforcing members 92, 92, 92, 92 are provided on a quadrangular floorboard panel 91, and a steel frame bundle (strut) 95 is provided at a central portion which is an intersection of the four radial reinforcements 92, 92, 92, 92. 95 and radial reinforcements 92, 92, 9
Four cables 96, 9 between the end portions of 2, 92
You may make it attach the panel unit 90 which stretched 6,96,96 respectively.

In the above embodiments, the roof panel attached to the steel truss of the dome type roof or the floor panel provided between the girders in a general building is used, but the present invention is not limited to this. Instead, it may be a large span roof panel, floorboard panel, wallboard panel, or the like that is attached to the frame of a general building. Further, the material and shape of the panel material are arbitrary, and it is needless to say that the specific detailed structure and the like can be appropriately changed.

[0027]

As described above, according to the panel unit of the present invention, the tension of the radial cable pushes up the intersection of the reinforcing members by the axial force of the bundles arranged substantially vertically, that is, the panel member. Since the bending stress of the reinforcing material can be reduced by pushing up the substantially central portion of the reinforcing material, the reinforcing material can be made light.

Therefore, for example, as described in claim 2,
At each tip of the reinforcing material provided corresponding to each corner of the polygonal panel material, it is possible to join it to the skeleton, and in particular, the beam material and the purlin material are unnecessary, and it is economically dome type. The total load or most of the load on the roof panels can be transferred directly to the intersection of the steel trusses of the roof.

Further, according to the present invention, since the panel unit, the reinforcing member, the bundle member, and the cable are assembled in advance in the panel unit, it is possible to quickly, for example, a roof by joining work at a few places on site. Can be finished, shortening the construction period,
Improved safety can be achieved.
