Abstract

PROBLEM TO BE SOLVED: To improve conventional laborious and time-consuming pile driving operations. SOLUTION: Twisted flat steel obtained by twisting flat steel is used in place of a conventional pile. Because the pile using the twisted flat steel can be placed upright by simply driving into the ground, it needs less labor and is quicker to install.

ので、労力が要らず時間もかからない。Therefore, in the present invention, a twisted flat steel obtained by twisting a flat steel is used in place of the conventional pile. As shown in Fig. 1 (a), this twisted flat steel pile can be easily screwed to the ground simply by hitting the head with a material that has both ends cut to an appropriate length and one end sharpened slightly. It takes less effort and takes less time.

る。[0005] Next, simply screwing the twisted flat steel pile into the ground makes it impossible to mount anything on it. So Figure 2
As shown in (1), a bolt (2) or a long nut (3) was welded to the end of the twisted flat steel (1). In this way, various things are attached to the pile, and the use is expanded.

大きいと言える。[Operation] Here, the performance of the conventional pile and the twisted flat steel pile are compared. First, when pulling out a conventional pile that has been driven into the ground,
Since only the frictional force between the periphery of the pile and the soil acts, it comes out with some force. On the other hand, when pulling out a twisted flat steel pile screwed into the ground, the spiral flat steel is screwed into the ground like a cork opener, so the twisted flat steel must be turned. If the ground does not break, it will not come out. Since the same thing can be said when pushing in, it can be said that the pulling force and the pushing force of the pile are much larger in the twisted flat steel pile than in the conventional pile.

施例を説明する。BEST MODE FOR CARRYING OUT THE INVENTION The torsion flat steel pile of the present invention can be used as a pile where conventional piles are used. I do. Wooden sidewalks, such as those found in wetlands, are made by driving wooden stakes into places that are difficult to walk, and then making boards on top of them to make it easier to walk. Therefore, an embodiment using a bolted torsion flat steel pile instead of the wooden pile will be described.

a) is welded and the other end is fitted with a round bar (4). The presence of a round bar facilitates positioning when screwed in. Further, in this case, a washer (5) for receiving the square bar is attached to the end on the bolt side.

A square member (6) having holes at both ends is placed on the hole, and a bolt is inserted through the hole, and the leg is completed by tightening with a nut (3a). Next, a number of these legs are installed, and a plate (7) is laid on the timber to stop, thereby completing the sidewalk.
