Description
Technical field
The present invention relates to a kind of column muscle control methods in place, and in particular to column muscle is quickly at a kind of PC Structure Beam-column node
Position construction method.
Background technique
At home and abroad development speed is very fast for prefabricated construction, and in China, prefabricated construction construction technology is mature
Degree be not also it is very high, especially PC structural elements connecting node tectonic sieving and component be accurate, quick aspect in place, reinforce
It is a major issue for being currently badly in need of capturing to component connecting node tectonic sieving, construction and quick location control, to subtract
Few cost.
Summary of the invention
Goal of the invention: the present invention aiming at the shortcomings in the prior art, uses control during PC Structure Beam-column node construction
Molding jig lifts quickly auxiliary tool in place as prefabricated post, by control mold to bean column node before the lifting of upper segmented column is in place
Column muscle position after place column muscle position and node concrete pour carries out repeatedly adjustment and control, it is ensured that column muscle energy when construction in later period
It is enough quick, accurate in place, lifting efficiency is effectively increased, a large amount of mounting cost is saved, greatly shortens a kind of PC knot of duration
The quick construction method in place of column muscle at structure bean column node.
Technical solution: the quick construction method in place of column muscle at a kind of PC Structure Beam-column node of the present invention, including such as
Lower step:

The checking and accepting of column processed is more than the component of code requirement to column muscle design position deviation, forbids to march into the arena；
(2) prefabricated post lifting front pillar muscle position adjustment: prefabricated post is secondary prefabricated using control mold inspection before lifting
The deviation situation of column column muscle, and just successive step appropriate is carried out, column muscle excessive error as caused by the human factors such as lifting
Component, when construction also forbids to lift, be lifted after to be adjusted；
(3) lifting of prefabricated post: the precast column unit of control mould secondary passed examination has been passed through to column muscle, can carry out
Lifting construction, when lifting, will reinforce the protection work to component, and the especially protection to column muscle avoids the factors such as lifting collision from leading
Column muscle position is caused to generate biggish deviation.It therefore, also will be by code requirement to the column muscle error in place and to prefabricated post in place
It tightens control；
(4) lifting of precast beam: before hoisting beam, the Hoisting Position of check column and adjustment, the good beam of bullet is in place on shaft
The lifting of the laggard cross girders of control line, and the lifting error of beam is rationally controlled, while avoiding interference pre- in precast beam hoisting process
Column column muscle processed；
(5) bullet controls mold control line in place: after prefabricated beam column lifting is in place, will control mold in the top surface of precast beam
Position line pop-up pops up control mold control line in place, again based on the position line for controlling mold again preferably in order to the later period
Check work in work progress；
(6) bean column node template construction；Template uses aluminum dipping form at bean column node, guarantees node concrete presentation quality,
During formwork, the protection of column muscle at Ying Jiaqiang node；
(7) bean column node concreting with vibrate；It carries out bean column node concreting according to design requirement and vibrates,
Column muscle is avoided in work progress crosses large disturbances；
(8) control mold installation, fixed: bean column node concreting is finished with vibrating, before concrete initial set, according to
The control die location line and control line of prefabricated top surface of the beam carry out the installation of control mold immediately and fix, and are passed through and are fixed using steel wire
U-loop is fixed in beam body, is checked again for, is adjusted to column muscle position after fixed；
(9) control mold is removed, is had enough to meet the need: with regard to dismountable control after bean column node concrete actual strength, which reaches certain, to be required
Molding jig, and control mold is used in turn, the column muscle position after control mold is removed substantially has met lifting in place
It is required that the best position of check column muscle again；
(10) segmented column lifting is in place on: by having carried out adjustment control to column muscle position using control mold, in lifting
When segmented column can quickly, accurate contraposition, the lifting of segmented column works in place in completion.
Further, single column muscle position alignment error must not exceed 2mm before the prefabricated post in the step (2) lifts, always
Scapus muscle error must not exceed 5mm.
Further, the prefabricated post in the step (3) lifts control errors: plane error is no more than 2mm, and absolute altitude error is not
More than 3mm, the error of perpendicularity is no more than 0.4%.
Further, the error after the beam installation in the step (4) is fixed is no more than 2mm.
Further, the error of position line of control mold is no more than 3mm in the step (5), controls the control in place of mold
Linear distance position line 100-200mm, in order to carry out control and adjustment in place to control mold.
Further, being fixed temporarily for mold is fixed in beam body using steel wire across fixed U-loop in the step (8),
Wherein steel wire uses the high tensile steel wire of diameter 3-6mm, and the absolute altitude in place for controlling die top should be bigger than PC structure top surface of the beam absolute altitude
150-200mm, so that slot milling carries out the Local treatment etc. of node concrete.
