Description

[Detailed Description of the Invention] << Industrial Application Field >> The present invention relates to a cable fixing bracket for a membrane roof using a cable truss or the like.

<Prior Art> The applicant of the present invention had previously devised a lightweight large roof structure disclosed in Japanese Utility Model Laid-Open Publication No. 61-85607.

The membrane roof used for this type of large-scale structure uses a cable instead of a steel frame for weight reduction, and the cable supports the membrane.

In addition, the cable is stretched horizontally and vertically to give uniform tension to the membrane.

<< Problems to be solved by the device >> Therefore, there always exists a portion where the cables intersect with each other, and the shape of the membrane roof is maintained by definitely holding the positions of the cables at the intersections.

The present invention has been made in view of the above background, and an object thereof is to provide a cable fixing metal fitting for a membrane roof, which is capable of fixedly connecting the cables at a position where the cables intersect with each other and has good operability.

<< Means for Solving the Problem >> In order to achieve the above object, the cable fixing metal fitting of the membrane roof according to the present invention is a protective metal fitting for wrapping the cable at the intersection of the cable of the membrane roof supporting the membrane with the cable. A pair of crimping plates that are arranged to face each other across the intersection, and integrally formed with the pair of crimping plates, and project from the opposing surfaces of the crimping plates so that the pair of crimping plates respectively sandwich the protective metal fittings. A columnar fixing metal fitting and a bolt penetrating between the pressure-bonding plates, a nut is screwed into the bolt from the outside of the pressure-bonding plate, and the nut is tightened to compress the space between the pressure-bonding plates. The cable and the protective fitting are crimped and supported.

<Operation> According to the cable roof metal fitting of the membrane roof having the above configuration,
At the intersection of multiple cables that support the membrane that forms the membrane roof, wrap each of these cables with protective metal fittings, sandwich each of these protective metal fittings with columnar fixing metal fittings, and tighten the nuts screwed into the bolts. Thus, the pair of crimp plates are tightened to fix each cable.
At this time, since the protective metal fitting is held between the columnar fixing metal fittings, the fixing metal fitting can be bitten into the protective metal fitting by tightening the crimping plate, and the cable can be securely fixed.

In addition, since the fixing metal fittings have a columnar shape and are protruded from the crimp plates so as to sandwich the protective metal fittings arranged on each cable, if the number of cables intersecting at the intersection increases, the crimping plate This can be dealt with by increasing the number of fixing fittings projecting on the. Further, since this fixing metal fitting is provided integrally with each of the pair of crimp plates, even if three or more cables cross each other at the crossing point, each fixing cable can be secured without increasing the number of members of the fixing metal fitting. It can be sandwiched between the two and the mounting work can be simplified.

<< Embodiment >> Hereinafter, a preferred embodiment of the present invention will be described in detail with reference to the drawings.

Figure 1 shows a tension string cable 1 and a compression post 2
2 shows that the ridge cable 3 that supports the floor of the above is pushed up, and the ridge cable 3 that supports the membrane (not shown) of the membrane roof is supported on the top of the compression post 2.

Three ridge cables 3 intersect at the top of the compression post 2, and the intersecting directions are shifted by 60 ° in the circumferential direction.

The position of these intersecting ridge cables 3 is fixed to the fixing bracket 4.
I have decided.

The fixing metal fitting 4 is provided with a fixing metal fitting 6 between two disc-shaped crimping plates 5, and the fixing metal fitting 6 holds a pipe-shaped protective metal fitting 7 through which the ridge cable 3 is inserted.

Of the two crimping plates 5, a dowel 8 fitted into the compression post 2 is provided on the outer side of the lower crimping plate 5a, that is, at the center of the back surface.

The dowel 8 is fitted into the compression post 2, and a part of the outer peripheral surface of the compression post 2 is hit or pressured so that the dowel 8 and the compression post 2 are integrally pressure-bonded.

In this way, the centers of the crimp plates 5 and 5a and the compression post 2 are integrally connected and fixed.

 Further details are shown in FIGS. 2 and 3.

The fixing metal fittings 6 are paired in the upper and lower sides, and a through hole that is slightly flat in the longitudinal direction of the rectangular cube is punched, and this is split axially from the center of the through hole to obtain a sandwiched portion that is depressed vertically. There is.

Further, bolts 9 that penetrate the upper and lower crimping plates 5 and 5a are provided on the crimping plates 5 and 5a in order to press the fixing fitting 6, and nuts 10 are screwed into the upper and lower ends of the bolts 9.

The bolt 9 and the nut 10 are mounted on the crimp plates 5 and 5a at an interval of 60 °, and the fixing metal fitting 6 is also arranged at an interval of 60 ° avoiding the position of the bolt 9, and the fixing metal fitting 6 is crimped respectively. Board
It is fixed to the inside of 5,5a by welding.

Therefore, there are six fixing fittings 6 inside the crimp plates 5, 5a. And these 6 pieces are located so as to make a pair on the diameter line of the crimping plates 5, 5a.

In FIG. 3, protective metal fittings 7 are passed through the three ridge cables 3, mounted on the lower fixing metal fittings 6, and the upper fixing metal fittings 6 and the crimping plate 5 are mounted so as to cover them.

When the nut 10 is tightened through the bolt 9 as it is, the protective metal fitting 7 is compressed by the fixing metal fitting 6 and is constrained by the recess of the fixing metal fitting 6 while being compressed from the outer periphery and the protective metal fitting 7 and the cable 3 are integrated. Further, the protective metal fitting 7 is sandwiched and supported by the fixing metal fitting 6.

<Effect> As described in detail above, the cable fixing bracket for the membrane roof according to the present invention includes the protective bracket that wraps the cable at the intersection of the cables, so that the cable is not directly damaged and the protective bracket is attached from above and below. Since it has a fixing plate that sandwiches it, the fixing plate integrates the protective metal fitting and the cable, and the side of the cable fixing does not directly contact the fixing plate due to the shaking of the cable, so the position of the cable is fixed while protecting the cable. Can be sandwiched and held.

In addition, since the crimp plates are connected with bolts and the space between the crimp plates is compressed with a nut, the cable can be firmly positioned by simply tightening the nut, and conversely, the cable can be easily removed by removing the nut. There is an effect.

Further, since the protective metal fitting is sandwiched by the columnar fixing metal fittings, the fixing metal fitting can be bitten into the protective metal fitting by tightening the crimping plate, so that the cable can be securely fixed.

Further, since the fixing metal fittings have a columnar shape and are protruded from the crimping plates so as to respectively sandwich the protective metal fittings arranged on the respective cables, when the number of cables crossing at the intersection increases, the crimping board This can be dealt with by increasing the number of fixing fittings projecting on the. At the same time, since this fixing metal fitting is provided integrally with each of the pair of crimping plates, even if three or more cables cross each other at the intersection, each fixing metal fitting can be used without increasing the number of members of the fixing metal fitting. It can be securely sandwiched, and its mounting work can be simplified.
