Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial Application Field) The present invention relates to a roof structure, and more particularly to a net-like roof structure constructed so as to intersect with each other.

(Prior art) Recently, NIKKEI ARCHITECTURE 1 has been used as a roof structure for large-span buildings without internal supports.
73 (April 23, 1984 issue) and JP-A-60-258
As shown in Publication No. 376, roofs with cable net structures are constructed by applying tension to either or both of the upper and lower cables crossed in a lattice pattern, and roof finishing material is attached to the cables. A construction method has been proposed.

The roof of this structure uses the tension of the cable, so
Compared to conventional truss-type roof structures, the overall weight is lighter and it can be applied to large-span roofs.

However, the cable net structure roof described above has the following problems.

(Problem to be solved by the invention) In other words, it is necessary to lock the upper and lower cables at the intersection of the cables, but since the cables normally used in this type of roof structure have a circular cross section, The intersection points are curved surfaces that come into contact with each other, and it is difficult to make a strong connection without using a specially prepared coupling tool such as a U-bolt.

In addition, when attaching roof finishing materials such as thin steel plates to cables, it is not possible to attach them directly to the cables, so another member must be interposed to support the finishing material, and the mounting structure is complicated. Not only was this complicated, but the roof also became heavier.

Furthermore, in a typical roof structure, the same amount of stress does not act on a single cable at all locations, and the required stress differs depending on location. Therefore, if the cross-sectional diameter of the cable is changed according to the stress, it will be the most economical with less wasted material, but in reality only a small stress is required because the cables cannot be easily joined against such an economical design. Even if there are places where this is not possible, thicker cables that are suitable for places that require large stresses have to be used.

This invention was made in view of these conventional problems, and its purpose is to easily connect members that introduce tension, and to easily attach roof finishing materials. The object of the present invention is to provide a net-like roof structure that can be easily adapted to a stress-responsive design.

(Means for Solving the Problems) In order to achieve the above object, the present invention includes a plurality of suspension strips installed at predetermined intervals, and It is characterized in that it consists of a plurality of presser band plates arranged on the suspension band plate, and tension is introduced into the suspension band plate by tensioning the presser band plates.

(Function) According to the net-like roof structure having the above configuration, the intersecting parts of the suspension strips and the holding strips are in surface contact between the plates, so that
For example, they can be easily connected by bolts or spot welding.

Furthermore, even when it is necessary to accommodate stress in the middle of each strip, by changing the width of the strip and performing spot welding, a strip that can accommodate the stress can be easily obtained.

(Embodiments) Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

1 to 3 show an embodiment of a net-like roof structure according to the present invention.

The roof structure shown in the figure is the outer circumference of a rectangular building structure, as shown in its entirety in Figure 1! l! 10, an outer peripheral frame 12 disposed inside the outer peripheral wall 10 along the shape of the outer peripheral wall 10,
Four beams 14.14 are installed extending from the midpoint of each side of the outer frame 12 to the center, and the roof shape is the same in the rectangular portion defined by these outer frame 12° beams 14. There is.

FIG. 2 shows the main part of FIG. 1, and the roof is arranged almost parallel to a line connecting the center of the roof and one vertex of the outer peripheral frame 12, with a predetermined interval, and has both ends connected to beam members 14. Outer frame 1
2 and a plurality of suspension strips 1 fixed to each other by bolt connections.
6.16... and each hanging strip plate 16.16...
It is generally composed of a plurality of holding band plates 18, 18, which intersect with each other on the upper surface side so as to be substantially perpendicular to ..., and a roof finishing material 20 attached to the holding band plates 18. There is.

In this embodiment, each of the strips 16 and 18 is a flat metal plate (iron plate, stainless steel plate), commonly called a flat bar, with a width of about 100 m1 and a thickness of about 9 to 12+em.

The intersecting portions of the strips 16 and 18 are connected by bolting or spot welding.

In addition, in this embodiment, since a folded plate folded into a corrugated shape is used as the roof finishing material 20, a support material 22 having the same shape as the bent shape of the finishing material 20 is fixed to the upper surface side of the hanging strip 16. has been done.

To construct the roof with the above configuration, first, the hanging strips 16.
16... is fixed between the beam material 14 and the outer peripheral frame 12, and then the presser band plates ia,
is..., and connect each intersection.

Thereafter, the ends of the presser band plates 18, 18, .

As a result, each of the suspension strips 16, 16, . . . is pushed downward, and tension is also introduced into the suspension strips 16.

When tension is introduced in the above manner, as schematically shown in FIG.
. . . against the upward load, and the tension of the presser strips 18, 18 . . . against the upward load to ensure the stability of the roof.

When the erection of the strips 16 and 18 is completed, the finishing material 20 is placed on the support material 22 and these are fixed by welding or the like to complete the roof.

Note that when installing the finishing material 20, the troughs of the corrugations should slope downward from the center of the roof toward the eaves.

Further, the support material 22 may be fixed onto the presser band plate 18.

Now, in the roof structure configured as described above, unlike the conventional circular cross-section cable, strip plates 16 and 18 are used.
These intersections are joined by surface contact, and can be easily and firmly joined without using special joints.

FIG. 4 is an explanatory view of the main parts of the second embodiment of the present invention, and only its characteristic points will be explained below.

In the embodiment shown in the figure, the cross-sectional shape of one strip 16-18 is changed in the middle, and the width of another strip 16-18 corresponds to the required stress. Fig. 5 (a) shows the case in which the 18- parts are butted and welded together (Fig. 5 (a)), and the case in which they are joined by bolting (Fig. 5 (b)). The material can be used to complete the roof structure very economically.

In the above embodiment, the present invention is applied to an architectural structure with a rectangular plane, but the present invention is not limited to this shape, and can be applied to other shapes such as a horse saddle-shaped roof. can.

(Effects of the Invention) As described in detail in the embodiments above, according to the net-like roof structure of the present invention, the connection structure between members to which tension is introduced becomes Mill compared to the conventional cable net structure.

Furthermore, since the cross section can be easily changed, an economically superior roof can be formed with a cross section that corresponds to the required stress.
