Column body aligning pre-tightening seat with pre-tightening height adjustable function

Abstract

The invention discloses a column body aligning pre-tightening seat with a pre-tightening height adjustable function. The column body aligning pre-tightening seat comprises a base, six pre-tightening piles, lengthening sections and pre-tightening pressure rods. The base is arranged outside the bottom end of a cement column body, and the pre-tightening piles are fixed to the upper end face of the base; gaps are formed between the pre-tightening piles and the outer wall of the cement column body, and the lengthening sections are detachably assembled at the top ends of the pre-tightening piles andprovided with lengthening section slideways extending in the mode of being matched with slideways; the slideways with the same extending direction as the pre-tightening piles are formed in the surfaces of the ends, opposite to the outer wall of the cement column body, of the pre-tightening piles, and sliding blocks are assembled on the slideways in a sliding-fit mode; radial columnar grooves aremachined in the sliding blocks, the pre-tightening pressure rods are assembled in the columnar grooves in an embedded mode, and springs are arranged between the columnar grooves and the pre-tighteningpressure rods; and the other ends of the pre-tightening pressure rods are provided with rotatably-assembled pressing wheels. According to the column body aligning pre-tightening seat adopting the technical scheme, the pressing wheels are jacked on the outer wall to achieve tight jacking and pre-tightening.

Description

technical field [0001] The invention relates to the field of construction, in particular to a cylinder collimation and pretension seat with adjustable pretension height. Background technique [0002] At present, in the field of construction, before the cement column is completely hardened, it is necessary to hold the cement column to ensure its verticality; usually, multiple bamboo poles or metal senses are used to match the metal ring on the cement column. This structure The effect is minimal, and it is easy to cause damage to the surface of the main body; it is difficult to achieve through this structure when the holding position is high, and the holding strength will also drop a lot. Contents of the invention [0003] Aiming at the above technical problems, the present invention proposes a column collimation and pretension seat with adjustable pretension height. [0004] In order to achieve the above purpose, it is realized through the following technical solutions: ...
