Problems solved by technology

[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 this structure when the holding position is high, and the holding strength will also drop a lot;
[0003] Moreover, conventional technology does not have waterproof function

Embodiment Construction

[0032] Such as figure 1 and figure 2 A cement column waterproof collimation pretension seat shown, including:

[0033] Base 1, pre-tightening pile 2, extension section 3 and pre-tightening pressure rod 4;

[0034] The base 1 is arranged outside the bottom end of the cement cylinder, and the base 1 is a truncated cone;

[0035] The number of pre-tensioned piles 2 is 4, all of which are fixed on the upper end surface of the base 1, and the pre-tensioned piles 2 are all parallel to the cement column;

[0036] The installation position of the pre-tightening pile 2 is the end face of the upper ring of the base 1;

[0037] There is a gap between the pre-tensioned pile 2 and the outer wall of the cement cylinder;

[0038] The end face of the inner wall of the pretension pile 2 is provided with a slideway 5, and the slideway is provided with a slider 6 that slides and fits with the slideway 5;

[0039] The slide block 6 is provided with a columnar groove 6.1 with a single-ended ...

Abstract

The invention discloses a waterproof aligning pre-tightening seat for a cement column body. The waterproof aligning pre-tightening seat comprises a base, four pre-tightening piles, extending sectionsand pre-tightening pressure rods; the base is arranged outside the bottom end of the cement column body, and the pre-tightening piles are fixed to the upper end face of the base; the mounting positions of the pre-tightening piles are positions averagely dividing the end face of the annulus of the upper end of the base, and gaps are formed between the pre-tightening piles and the outer wall of thecement column body; slideways are formed in the end faces of the inner walls of the pre-tightening piles, and sliding blocks slidably matched with the slideways are arranged on the slideways; columnargrooves with one ends being open are formed in the sliding blocks, and the center lines of the columnar grooves are perpendicular to those of the pre-tightening piles; openings of the columnar grooves face the cement column body; embedded blocks are fixed to one ends of the pre-tightening pressure rods, and pressing wheels are rotatably assembled to the other ends of the pre-tightening pressure rods; and the extending sections are fixed to the top ends of the pre-tightening piles, and waterproof cover plates are arranged at the top ends of the extending sections in a hinged mode. According tothe waterproof aligning pre-tightening seat, linear pre-tightening is achieved through the pre-tightening pressure rods, and annular gaps between the cement column body and the extending sections areclosed through splicing and hinge joint of the waterproof cover plates capable of being opened and closed to achieve water resistance.

Description

technical field [0001] The invention relates to the construction field, in particular to a cement cylinder waterproof collimation pretension seat. 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 this structure when the holding position is high, and the holding strength will also drop a lot; [0003] Moreover, the conventional technology does not have a waterproof function. Contents of the invention [0004] Aiming at the above technical problems, the present invention proposes a cement cylinder waterproof collimation and pretension seat. [0005] In order to achieve the above purpose, it is realized throu...
