Abstract

PURPOSE:To simplify a pile jointing and insertion work without enlarging the diameter of a pile joint section. CONSTITUTION:Peripheral slits 6 and 7 are respectively drilled through both end sections of semi-circular ring pieces 1 and 1 of such shape as capable of being coupled to piles 11 and 14 to be jointed. Both pieces 1 and 1 are superposed on top of each other, and laid circularly in plan view. Also, wedge pieces 8 and 8a are inserted in the slits 6 and 7 made partly continuous to each other at the superposed sections 17 and 18 of the pieces 1 and 1 [view (b) and (c)], thereby constituting a jointing and temporary fastening device 9 for a pile [view (a)]. The device 9 is coupled to the joint section of the piles 11 and 14, and the wedge pieces 8 and 8a are lightly driven at the superposed sections 17 and 18 of the pieces 1 and 1. The rings 1 and 1 are thereby tightened, so as to reduce the diameter thereof. Then, the sections 17 and 18 are welded to complete a jointing work for the piles 11 and 14 [view (d)].

案されている（実開昭３−８３２２４号）。2. Description of the Related Art Conventionally, end plates are connected to each other by welding at the site for connecting piles. However, since the welding work of the end plates on site requires a skilled technique and is affected by the weather, the work efficiency is poor, and thus various connectors have been developed. For example, the semicircular inner rings 31, 31 are ring-shaped piles 32,
The inner ring 31 is fitted to the connecting portion of the inner ring 32, and the outer ring 33 is lifted by fitting the inner tapered cylindrical outer ring 33 (FIG. 6A). A joint structure for a pile in which the ring 31 is tightened (Fig. 6 (b)) has also been proposed (Japanese Utility Model Publication No. 3-83224).

Since it is necessary to loosely fit the outer ring 33 to the pile 32 before the piles 32, 32 are vertically aligned, there is a problem that it is difficult to handle. Further, there are some piles 32 having a diameter of about 1 m, and when the diameter is large, the outer ring 33 is also large, and there is a problem that it becomes more difficult to handle. In addition, since the inner and outer two rings are overlapped on the connecting portion, the diameter of the ring fitting portion 34 becomes large in the connected pile, and when the pile 32 is inserted, the portion hits the side wall of the pile hole and is difficult to insert, and the portion is small. There was a risk of damage.
