1results about How to "Guaranteed recyclability" patented technology

The utility model discloses a positioning control frame suitable for H-shaped steel, including longitudinal beam, two the longitudinal beam parallel interval arrangement, and the end part is fixed with a crossbeam respectively, and two longitudinal beams and the two crossbeams of end part constitute the main frame of rectangle together, the middle section fixed with two interval distribution crossbeams of two longitudinal beams, and the longitudinal beam of two adjacent crossbeams and its both sides constitutes the positioning frame of mouth character type together. The utility model connects the positioning frame of longitudinal beam and crossbeam composition integrative, and the construction is convenient, is applicable to general SMW method pile construction, and can be repeatedly used, and effectively guarantees the recycling of material. Can reduce H-shaped steel sinking positioning time, improves construction efficiency, reduces construction cost and shortens the period of construction, and social benefit and economic benefit are outstanding. Can accurately position the position of H-shaped steel quickly, improves the perpendicularity of SMW method, thereby can guarantee engineering construction quality.
