れる。That is, the hollow frame 16 for constructing the head connection part has an oblong box shape in which only the side plates 19 are stretched over a frame 18 made of angle material or the like, and the upper and lower sides and both lengthwise ends are open. Inward groove-shaped guide rails 20a and 20b are provided on both sides of the bottom, and the upper plate of the groove-shaped guide rails 20a and 20b is a cover plate 21a that covers both left and right sides of the upper end of the steel pipe pile column row l. , 21b. Further, each of the positioning fitting members 17 has a tapered fitting guide 23 protruding from the outside of the bottom of the bottomed cylindrical body 22 that fits into the steel pipe pile 3, and the hollow frame 16 for constructing the head connecting portion. 2 that fits into the groove-shaped guide rails 2Oa and 20b of
Two sliding bodies 24a and 24b are attached to the upper end of the bottomed cylindrical body 22 via connecting plates 25a and 25b, and these hollow frame 16 for constructing the head connection part and fitting member 17 for positioning are installed at the factory. The front part is manufactured and delivered to the site.

a, 25b are connected to cover plates (21a, 21b) on the side of the hollow frame 16 overlapping with bolts/nuts 26, and each fitting member 17 is fixed to the hollow frame 16. However, if the hollow frame 16 cannot be stabilized horizontally due to variations in the level of the upper ends of the steel pipe piles 3 and the upper ends of the junctions 7, the four corners of the hollow frame 16 may be fixed as shown in FIG. For example, the hollow frame 16 can be stably supported in a horizontal state by screwing and unscrewing the level adjustment bolts 27 screwed through both ends of the cover plates 21a and 21b. At this time, a mortar-filled portion 28 filled with soil and hardened inside the junction 7 serves as a surface that supports the hollow frame 16 via each level adjustment bolt 27.
Alternatively, a plate may be attached to the upper end of the junction 7, and the tip of the level adjustment bolt 27 may be received by the plate.

トで閉じて、頭繋部2を中空のままにしても良い。As described above, the hollow frames 16 are sequentially set on top of the steel pipe pile column row 1 so as to be continuous in the direction of the column row, and the ends of the adjacent hollow frames 16 are connected to each other at both ends of the hollow frame 16. They are connected by bolts and nuts using the plate 18a. Then, cover plates are attached to the free ends of the hollow frame 16 located at both ends of the head connecting part 2 to close them off. Thereafter, concrete is placed inside each hollow frame 16 and inside the bottomed cylindrical body 22 of each fitting member 17 to construct the head connecting portion 2. In this case, if necessary, it is possible to arrange reinforcement inside the hollow frame 16 to make it made of reinforced concrete, but this reinforcement work should be done when the hollow frame 16 is manufactured at the factory, and the arrangement at the construction site. Muscle work can also be eliminated. Of course, if the size of the head joint 2 is small, pouring concrete into the hollow frame 16 is omitted, and the upper opening of the hollow frame 16 is closed with a cover plate, leaving the head joint 2 hollow. Also good.

幅に低減することが出来る。(Operations and Effects of the Invention) The construction method of the present invention can be implemented as described above, and according to the construction method of the present invention, a hollow frame for constructing a head connection part is placed on the constructed steel pipe pile column row. After each lower positioning fitting member is transferred so that it fits inside the upper end of the steel pipe pile, each of the fitting members and the hollow frame are fixed, and if necessary, concrete is poured into the hollow frame. This eliminates the need to assemble concrete formwork for constructing head connections on steel pipe pile column rows and to dismantle and remove formwork after concrete curing, reducing man-hours for manufacturing head connections on site. It can be significantly reduced.
