Description

Method for controlling pouring forming quality of concrete batter post

Technical Field

The invention relates to the field of building construction, in particular to a method for controlling the pouring and forming quality of a concrete batter post.

Background

The traditional concrete batter post pouring construction mainly has the following defects:

1. the batter post design inclination is big, and the reinforcing bar is denser, and the vibrating rod can't extend the bottom from the top smoothly during concrete placement, even stretch down also can't vibrate closely to batter post facade side concrete, and the vibrating rod is very easily blocked by the stirrup when lifting moreover.

2. When the batter post is poured and vibrated, concrete bubbles are not easy to discharge and can be accumulated on the outer vertical surface side of the batter post, so that the quality problems of honeycombs, pitted surfaces and the like of the appearance of the concrete after the form is removed are caused.

3. The inclined column stirrup is generally designed to be fully-encrypted, the stirrup forms an inclined plane on the inner vertical surface side of the inclined column, and when concrete is poured, the aggregate of the concrete is easily clamped by the stirrup, so that cement paste cannot wrap the reinforcing steel bars, and exposed reinforcing steel bars appear after the formwork is removed.

Disclosure of Invention

The invention aims to overcome the defects of the prior art, provides a method for controlling the pouring forming quality of a concrete batter post, and solves the common quality problems of honeycombs, pitted surfaces, holes, rotten roots and the like existing after the pouring of the batter post of a frame concrete structure.

In order to solve the technical problem, the invention is realized as follows:

a method for controlling the pouring and forming quality of a concrete batter post is characterized by comprising the following steps:

step 1: coarse aggregates with small particle sizes are selected as concrete mixtures, self-compacting concrete is adopted, the concrete slump is controlled to be (200 +/-20) mm, the fluidity of the concrete is enhanced, the concrete can be automatically filled to all corners of an inclined column as much as possible during pouring, and the concrete can be better covered and wrapped with reinforcing steel bars;

step 2: when the batter post is installed on a template, a hole of 200mm x 200mm is reserved on the outer vertical surface side of the batter post every 1000mm, and the two purposes of reserving the hole are as follows: firstly, the air vent hole is used for pouring the concrete of the inclined column, and secondly, the vibration hole is used for pouring the concrete of the inclined column;

and step 3: before concrete pouring, watering the inner side of the column mould for moistening the mould, and plugging the joint at the root of the column mould by adopting common mortar so as to avoid root rot after the inclined column is formed due to slurry leakage during pouring;

and 4, step 4: before the batter post is poured, 50-100 mm of stone reducing mortar which is mixed with concrete is poured at the bottom of the batter post for filling, so that a slurry guiding effect is achieved, the phenomenon that aggregate and slurry are separated during high-position pouring of the concrete, root rot occurs in the batter post, and concrete pouring is carried out after the stone reducing mortar is poured;

and 5: when concrete is poured, the concrete is vibrated along with pouring, an inserted vibrating rod is inserted into holes reserved on the outer vertical surface side of the batter post for layered vibration, and the layered vibration height is not more than 500 mm;

step 6: a small-sized inserted vibrating rod point-contact type auxiliary vibrating template is adopted outside the batter post template, so that concrete bubbles on the inclined vertical surface around the batter post are discharged from the reserved holes, and the effect of compaction is achieved;

and 7: when concrete is poured to the reserved hole, arranging a professional rebar builder to immediately restore and firmly bind the diagonal column stirrups at the reserved hole, then arranging a carpenter to immediately block and reinforce the reserved hole, and repeating the steps until the diagonal column is poured, so that a construction joint cannot be reserved midway;

and 8: the inclined columns are provided with support surfaces of the inner vertical surfaces, and the templates of the other three vertical surfaces can be completely removed under the condition that the concrete is ensured not to have unfilled edges or fall corners.

The invention has the beneficial effects that: compared with the traditional batter post pouring construction, the control is carried out on the aspects of concrete raw materials, a template installation mode, a concrete pouring vibration mode, detail treatment and the like, so that the common quality problems of honeycombs, pitted surfaces, holes, rotten roots and the like after the concrete batter post is poured are effectively controlled, the rework repair cost is reduced, the appearance quality of batter post forming is improved, and the structural reliability of the batter post after pouring is ensured. For projects needing to create high-quality awards of project structures, the forming quality of the inclined columns is undoubtedly the key point of the acceptance of the appearance quality of the solid structures, and the awarding evaluation passing rate can be greatly improved through the method.
