Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a field clamp for reliably fastening the crossing portions of cables in structural buildings such as air membranes and tension membranes.

For example, in the case of a pneumatic membrane structure, when decorating the membrane constituting the roof, a cable is stretched in advance, and a membrane is stretched in each area surrounded by the cable. However, if the intersection points of each cable are not fixed, and the minus intersection points are shifted, the width of the membrane will not match the width of the area surrounded by the couple, making it difficult to attach the membrane to the cable. For this purpose, the cable intersections must be fastened with clamps to prevent the membrane from shifting during installation.

The purpose of the present invention is to ensure that the intersections of the cables can be fastened securely, and another purpose is to prevent the cables from being damaged by contact with the clamps.

The cable clamp according to the present invention includes one tube body that grips one cable at the intersection of the couple, another clamp body that grips the other couple, and a bolt that presses one tube body toward the other cable side. and a base plate which is removably connected to this bolt via a hollow plate and which presses the other tube body against one couple side by tightening force. Both tubes are divided into two parts and consist of an outer tube part and an inner tube part. The inner tube portion of one adjacent tube and the inner U rod portion of the other tube are fixed to each other. The entire inner periphery of the end opening of each tube body has a chamfered cutout surface to prevent the outer periphery of the cable that moves vertically and horizontally from coming into contact with the inner periphery of the inner periphery and being damaged. . It is desirable that the inner peripheries of the openings at all ends of both tubes be cut surfaces. Further, the outer tubular body portion of one of the tubular bodies is suppressed by the bolt directly or indirectly. In other words, when the bolt is a U-bolt, the outer peripheral surface of the outer tubular body of one of the tubular bodies can be directly pressed against the inner surface of the circular arc portion of the bolt. When the bolt is suspended from the inner surface of the plate using a flat holding plate, it can be indirectly suppressed through this holding plate. If the outer tube part of one body 'a' is fixed to the arc part of the U bolt or the inner surface of the holding plate, and the other outer tube part is fixed to the inner surface of the base plate, the main part of the cable clamp is fixed. is a part consisting of the bolt and the outer tube part of one tube body, a part consisting of the inner tube part of one tube body and the inner 'U body part of the other tube body, and a part of the other tube body. 3F of the part consisting of the outer pipe body part and the base plate
It can be made into 1B, making it easy to transport and install. A latching portion for supporting wires and the like is provided on the outer surface of the base plate.

Embodiments of the present invention will be described below based on the drawings.

In Figs. 1 to 3, the steel pipe bodies 1 and 2, which are located in an intersecting state, are meant to hold one couple C and the other couple Ca' (5) at the cable intersection, respectively. The length is set to provide gripping strength.The inner periphery of the opening at both ends of each tube body 1, 2 is formed with a notch surface 3 that is chamfered in a tapered shape over the entire circumference. The tube l is divided into upper and lower halves to form the outer tube 9.
1m and an inner tube portion 1b, and similarly, the other tube 2 located in the divided F direction also consists of an outer tube portion 2a and an inner tube portion 2b. The inner tube portions ib and 2b, which are in instant contact, are connected in a crossing state by welding via the connecting plates 4 and 4t, and both tube portions determine the crossing angle of the crossing cables C and Ca and fix the intersection point. A pair of U-shaped bolts 5.5 are attached to the outer tube part 1a of the upper tube 1 so as to sandwich the lower tube 2.
The arc part of the bolt is connected to the outer tube body part 1 of the tube body.
It is fixed to the outer peripheral surface of a by welding. The bolt 5.5 hangs below the tube body 2, and the outer tube body 2at-
A flat diamond-shaped base plate 6 made of 11111 that is pressed toward the couple Ca side is held in a horizontal state by nuts 7.

The base plate 6 is integrated with the outer tubular body portion 2a of the tubular body 2 by welding. Further, a latch plate 8 serving as a latch portion is vertically provided on the pace plate 60F surface, and a latch hole 8a is provided in this latch plate.
is the provision. This latching plate is used to suspend the cable in an appropriate manner in order to insert the wire into the bolt fixing hole 8a and fix the cable automatically when constructing the couple.

Next, how to use it will be explained.

First, the outer tube part 1a of the tube l is placed on the cable C located above the intersection of the couple, and then the cable C crosses the integrated inner tubes 111b and 2b.
, Ca, receives the upper cable C with the upper inner pipe body tfiIlb, places it on the lower couple Ca with the lower inner pipe part 2b, and determines the crossing angle of both couples,
When the base plate 6 is attached to the lower end of the bolt 5.5 from the bottom of the lower couple, at the same time, the outer tubular body portion 2a grasps the couple Ca together with the inner body 2b, and finally the bolt 5.5. Attach nut 7 to the lower end of 5 and tighten. By this tightening, the base plate 6 presses the outer U body part 28 against the upper blade, and since the outer tube body part 2a is in a fixed state, the position of the tube body 1.2 is identified by this pressing force. At the same time, firmly grasp the internal cable C1Ca.

Another example of the bolt is shown in FIG. In this example, pol)1
5.15 The outer tubular body portion 1a is hung down from the lower surface of the presser plate 9, and the outer tubular body portion 1a is fixed to the lower surface of the presser plate by means of bath contact. Compared to the U-shaped bolt 5 in this example, there are more parts than the holding plate, and when the nut is tightened, the pressing force on the cable is passed through this holding plate, but the function of the U
It's no different from the bolt example.

As explained above, according to the present invention, the two intersecting tubes are fixed with bolts and the base, and the inner tube portions of both tubes are integrated in an intersecting state, so that the intersection of the cables can be reliably tied and fixed, and since each tube body is divided into two parts, it can be followed even if the diameter of the couple changes.

Furthermore, since the inner circumferential edge of the opening at the end of the tube is a notched surface, the couple is not damaged by the inner circumferential edge.
