Height-adjustable prestressed tendon height positioning device

Abstract

The utility model belongs to the field of building construction technology, concretely relates to a height -adjustable prestressed steel bar height -above -ground positioning device, including support and height adjusting spare, the support includes a vertical rod and two inclined struts, two inclined struts are symmetrically fixedly connected in the left and right sides lower part of vertical rod, height adjusting spare is screwed in vertical rod outside, height adjusting spare is located above inclined strut, the left and right sides middle part of height adjusting spare is symmetrically fixedly connected with two support plates, the upper surface of two support plates all is set up with the placement groove, and the placement groove is placed with prestressed steel bar. The utility model adjusts the height of support plate and prestressed steel bar through height adjusting spare, carries out accurate positioning to each height -above -ground control point of prestressed steel bar, and the applicability is strong, improves construction efficiency, reduces construction cost, and the placement groove is wrapped to the bottom and both sides of prestressed steel bar and supports it, avoids the disturbance of prestressed steel bar when pouring or vibrating concrete, and the stability is high, and then can ensure that height -above -ground is accurate, and curve is smooth.
