摘要
Methods are used to reinforce the brace legs within the square mechanism of the brace leg rims. This method comprises attaching the spreader 3 to one end of each brace leg 2, while attaching the extendable tension unit 4 to the other end of the same brace leg 2. Next, the brace leg 2 is placed inside the drill hole so that the end of the brace leg 2 terminated at the spreader 3 at the corner of the drill hole is connected to the end of the next brace leg 2 terminated at the tension unit. Be placed. When all the brace legs 2 are coupled to each other, the tension unit is attached to the next brace leg 2 at the corner of the drilling hole with the end of the brace leg 2 attached to the brace leg 2 with the spreader 3 attached. 4 presses against the sheet pile 1. In the mechanism according to the invention, the spreader 3 is attached to one end of each brace leg 2 forming the rim of the brace leg supporting the drilling hole sheet pile 1, whereas the tension unit 4 is the same brace leg 2. Attached to one end. The tension unit 4 has an I-shaped member 41, an axially arranged lug 42 is installed at one end of the I-shaped member 41, and a holding block 43 is firmly installed on the opposite side. A slide panel 5 exists between the axially arranged lug 42 and the holding block 43. The slide panel 5 is composed of a base plate 51 projecting beyond the contour of the I-shaped member 41, a spacer plate 52, and a limiting plate 53. The base plate 51, the spacer plate 52, and the limiting plate 5 are integrally formed in an I-shape. Surrounds the flange of the material 41. A lateral holding element 55 and two lateral lugs 57 are present and welded to the base plate 51. Further, there are a block hole 44 and a tension hole 56, and the tension stud 7 penetrates both of them. At each corner of the rim of the brace leg 2, a spreader 3 attached to the brace leg 2 of one of the first pair of brace legs is fitted by a pin 8 to the brace leg containing the second pair of brace legs. Combined with the tension unit 4.
