Referring to FIG. 7, the connecting structures are likewise narrow passage members 43 and 44. outside narrow road Member 43 has a short cavity 45 and an elongated end 47 with an inwardly folded end 47 for reinforcement. It has a cavity 46. The inner surfaces 48 of the cavities 45 and 46 widen outward. Ru. The inner narrow channel member 44 has two relatively short straight cavities 49 with parallel outer surfaces 50. have. This arrangement of cavities 45, 46, and 49 narrows the narrow passage member 44. Consideration is given to ease of insertion into the channel member 43. This is also This will provide a narrower connection between adjacent arcuate elements.

In FIG. 8, the outer conduit member 51 is flared outwardly and as shown at 53. It has a cavity 52 with a step inside. The inner narrow passage member 54 is directed outward. It is contracted and has a cavity 55 with an inwardly bent end 56 for reinforcement.

Due to the form of the narrow path members 51 and 54, the narrow path members 51 and 54 can pivot or oscillate on the aforementioned restricted axis. movement becomes possible.

Finally, in FIG. 9, the outer narrow channel member 57 again has an outwardly flared inner surface. It has a cavity 58 provided with a surface 59. However, in this example, the inner narrow passage 60 faces one side of the panel as shown (either side is fine), and the base 63 of the narrow passage opposing planes defined by the outer surface of the narrow passageway cavity 64 and the outer end of the narrow passageway cavity 64, respectively. Row surfaces 61, 62 are provided. In this form of narrow passage member, three parallel Web A1. There is B1, and CI, and the structure of the connection part is as described above (see Figure 5). Responsible for most of the structural strength.

Where the wedge hole 30 is provided The holes are also aligned correctly to form an L-shaped cock with a groove 68 near one end. The connection is made between the plate 67 and the wedge 69 (Fig. 3C), and the cock plate is inserted into the groove 68. 67 to fasten the panels together (Figure 3B).

The inner and outer connecting structures are illustrated, for example, in FIG. 5 and described with reference to FIG. When engaged with each other, it is obvious that a very strong and rigid box-shaped cross-section bond is created. provided. and once there is no mechanically flexible connection between adjacent arcuate elements. Compensating for or adjusting for the changes and irregularities present in the formation, the precipitation of the formation Due to the lower weight, adjacent arcuate elements can be temporarily connected to each other until they come together. , this is not an essential requirement for the underpass support of the invention to be lignically stable.

Of course, adjacent arcuate elements can remain connected to each other throughout the life of the underpass support. Both are possible.

This connection may be made in any suitable manner, but as shown in Figures 10 to 12, illustrates a preferred removable and reusable gripping device. Ru. The connecting structure illustrated in these figures is that shown in FIG. They are a narrow passage body 31 and an inner box member 32.

The gripping device of FIG. 10 consists of two L-shaped members 70, 71 pivoting about a pivot 72 , forming a U-shaped clamper.

A handle 74 is pivotally mounted between the two links on one side of the A cam 75 is provided at the end adjacent to the clamper, and the adjacent L-shaped member 71. An arcuate spring 76 is coupled to the L-shaped member 71. This biases the adjacent connecting structure, in this example the narrow channel member 31. this spring 76 is the width of the dimensions resulting from manufacturing tolerances in the panel-to-panel connection structure. fill in the space well.

The downward movement of the handle 74 causes the cam 75 to urge the L-shaped member 71 and the pivot shaft 7 2 and push it towards the L-shaped member 70, thus pushing the connecting structure 3 1 and 32 are combined with each other. On the other hand, by moving the handle 74 upward, the cam 7 5 to release the L-shaped member 71 from the pressure on the connecting part, and thus grip it. Allows for removal of the device. The presence of spring 76 allows the gripping device to be more easily connected to the operator. It will not come off unless it is actively removed from the knot. Such gripping devices are generally Several pieces are provided spaced apart in the longitudinal direction of the connecting part.

Referring to the other gripping device of FIG. 11, the L-shaped member 71 has a step; As shown in 7, there is a recess, and the lower cavity 33 of the narrow passage member 31 is engaged with the connecting portion. The gripping device can be engaged accurately and positively. here the arcuate The screw 76 is biased against the side 27B of the panel to which the sheath +A'32 is welded. I understand. ■ The --shaped member 71 has a hole 78 formed at its corner end, and has a gripping device. suspending an object, such as a tool, from the gripping device, or attaching the object to a gripping device; Or, it is provided for hanging the gripping device in the storage area.

Finally, referring to FIG. 12, the gripping device is made of wire at the connection between the arcuate elements. , the U-shaped member 79 for fixing or gripping is held by a spring lock. The gripping U-shaped member 79 has an inwardly bent end to form a U-shaped gripping member 79. An arm 80 is pivotally connected to the shaped member 71 at 81 and is integral with the lever part 82. and engages a hole defined by a U-shaped member having a U-shaped member. If indicated by a dashed line The spring lock is shown in the gripping position - in the unlikely event that the spring lock shown in dotted lines is released. Indicates that it is in the correct position.
