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, NfKKEI ARCHITECTURE 1 has been used as a roof structure for large-span buildings without internal supports.
73 (April 23, 1984 issue) and JP-A-60-25
As shown in Publication No. 8376, the top and
A roof with a cable net structure has been proposed in which tension is introduced into one or both of the lower cables and a roof finishing material is attached to the cables.

The roof of this structure uses the tension of the cable, so
Compared to conventional truss-type roof structures, it is said to have a lighter overall weight and 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.

Also, when attaching roof finishing materials such as thin steel plates to cables, they cannot be attached directly to the cables.
Another problem must be provided to support the finishing material, which not only complicates the mounting structure but also increases the weight of the roof.

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. To provide a net-like roof structure that allows one tension-introducing material to be used also as a roof finishing material and that can be easily designed to accommodate stress.

(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 A roof structure consisting of a plurality of retainer strips arranged in a roof structure, in which tension is introduced into the suspension strips by tensioning the retainer strips, the retainer strips being lower than the suspension strips. It is constructed of wide thin plates, and these thin plates are placed closely together to serve as the roof finishing material.

(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, it can be connected to am by bolt connection or spot welding.

Furthermore, since the holding band plates are made of wide thin plates and are closely arranged, the holding band plates can also be used as a roof finishing material.

Furthermore, even if the required stress is to be accommodated 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 this figure is applied to a horse saddle-shaped roof that covers the outer peripheral wall 10 of an elliptical building structure, as shown in its entirety in FIG. 1. An outer circumferential frame 12 is provided at the upper end of the outer circumferential wall 10, and is formed along the shape of the outer circumferential wall 10.

FIG. 2 is a sectional view of the main part of FIG. 1, and the roof is constructed by hanging strips 14 installed in the left-right direction of the outer peripheral frame 12 and perpendicularly to the upper surface of the hanging strips 14. The intersecting portions of these plates are connected by spot welding or bolt connection.

In this embodiment, the suspension strip plate 14 is a fully bent flat plate (iron plate, stainless steel plate) commonly known as a flat bar with a width of about 100 m and a T1 thickness of about 9 to 12 sui.

Aluminum plates (aluminum plates) are used, and are attached to the outer circumferential frame 12 by bolting at both ends so as to be parallel to each other at a predetermined distance from the outer circumferential frame 12.

The presser band plate 16 is a wide thin plate that is wider than the suspension band plate 14 of the flat bar and has a thinner thickness.
These thin plates are placed closely together and serve as roof finishing material.

In addition, the six-pressing band plate 16 is bent upward at both ends along its longitudinal direction to have a substantially concave cross section, and is brought into close contact with the bent portion 1.
The 68 pieces are joined together by welding or sealing to prevent rainwater from entering.

In this case, the presser band plate 16 may be formed into a flat plate, and the longitudinal ends thereof may be overlapped and bonded to each other.

To construct the roof with the above configuration, first, the hanging strips 14.
14... is fixed between the outer peripheral frame 12, and then the presser band plates 16° 16... are installed almost perpendicularly thereto.
... and connect each intersection using spot welding, etc.

Thereafter, both ends of the presser band plates 16, 16, .

As a result, each of the suspension strips 14, 14, . . . is pushed downward, so that tension is also introduced into the suspension strips 14.

When tension is introduced in the above manner, as schematically shown in FIG.
The tension of the holding strips 16, 16, . . . opposes the upward load, and the stability of the roof structure is ensured.

Now, in the roof structure configured as above, unlike the conventional circular cross-section cable, strip plates 14 and 16 are used.
These intersection points form surface contact and can be easily and firmly connected without the use of special coupling tools.

In addition, the roof has hanging strips 14 and holding strips 16 that also serve as finishing materials.
Since the structure can be constructed with the following steps, the structure is extremely simple and the weight of the roof is also significantly reduced.

FIG. 5 is an explanatory view of the main parts of a second embodiment of the present invention, and only its characteristic points will be explained below.

The embodiment shown in the figure is a case where the cross-sectional shape of one suspension strip 14 is changed in the middle, and when another strip 16- of a width corresponding to the required stress is butted and welded ( Figure 5(a)) and the case of bolting (Figure 5(b)) are shown, respectively, and both are easy to connect and are extremely economical using materials that can handle stress. The roof structure can be completed.

In the above embodiment, the present invention is applied to a horse saddle-shaped roof, but the present invention is not limited to this shape and can be applied to other shapes as well.

In addition, if the roof slope is relatively gentle, the holding strip plate 1
6, fold the folded plate into a wave shape into a narrow width liy1wI+
It can also be used separately.

(Effects of the Invention) As explained 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 can be easily formed compared to the conventional cable net structure of 5%. Moreover, since one of the tension introducing members also serves as a roof finishing material, it is lighter and can be applied to architectural structures with a relatively large span.

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.
