Description
Technical field
The present invention relates to building construction, secondary structure construction field, and in particular to a kind of secondary structure constructional column reinforcing side
Method.
Background technology
In current building trade, masonry structure needs to add constructional column to strengthen masonry globality, the template of constructional column
Reinforce mainly using the punching sleeve-penetrating combination wood stupefied on masonry structure and the conventional practice of steel pipe reinforcing template.Its shortcoming be
Punching can destroy the globality and compression strength of masonry structure on masonry wall, the stability of wall be reduced, to follow-up plastering process
Cause the mass defects such as hollowing, crackle.
The documents 1 of Application No. 201420504673.6 disclose a kind of construction column template building block, directly with construction
Column template building block pours mould as constructional column, and constructional column can be constructed simultaneously with wall, without formwork, but needs to customize and builds
Block, cost improve, and do not consider each department building block level of production difference and work progress in damage to building block mould and
Transport loss.The documents 2 of Application No. 200920217311.8 disclose a kind of constructional column sleeve bolt formwork system, adopt
With being embedded in from top to bottom in the horizontal mortar joint of horse tooth trough both sides and length and the PVC sleeve pipes of constructional column masonry consistency of thickness,
Split bolt is worn in PVC sleeve pipes and realizes that construction is easy to control to the drawknot of constructional column, saves construction cost, save fee of material and
Labour, but due to the requirement principle that specification must not punch to masonry wall, therefore take masonry wall sleeve-penetrating drawknot no longer feasible,
The program do not consider in mortar joint bury sleeve pipe violate in specification to mortar joint control requirement, with sleeve pipe to masonry rigidity, intensity,
Globality, masonry adverse effect attractive in appearance.
The content of the invention
The technical problem to be solved in the present invention is, for existing Constructional Col-umn Construction above shortcomings, there is provided one kind two
Secondary structure constructs column reinforcing method, and fundamentally solving the problems, such as that constructional column formwork is reinforced must punch on masonry structure,
Avoid the drawbacks of masonry structure causes wall integrity and compression strength step-down because constructional column formwork punches.
The present invention is that technical scheme is used by solving above-mentioned technical problem：
A kind of secondary structure constructs column reinforcing method, comprises the following steps：
1）Play constructional column center line, absolute altitude control line；
2）Mast axis, absolute altitude control point pilot measurement to post side, colligation constructional column post muscle will be constructed；
3）Screw arbor with nut at both-ends and the horizontal tension rib of wall are welded；
4）According to constructional column center line, the constructional column cage bar position welding of 4 ~ 6cm eminences is T-shaped fixed on away from constructional column post root
Position reinforcing bar, to control construction column cross-section size and axial location（Position-limiting action）；
5）5mm pastes wide sponge strip on the outside of constructional column post skin, to ensure that lower mouth and seam are tight；
6）Installation constitution column template, construction column template include the support of post inner cross type and post surrounding exterior sheathing；
7）Installation constitution post tie, wherein styletable captivate wood reinforcement with the screw combinations butterfly welded with horizontal bar and carried on the back
Stupefied steel pipe carries out formwork reinforcement；
8）Construct column template correction, reinforce；
9）Pour into a mould post concrete；
10）Form removal when post intensity to be constructed reaches design strength, 8 ~ 12mm depths are picked out in pre-buried Screw arbor with nut at both-ends cut-off part
Pit, the Screw arbor with nut at both-ends stretched out is cut off along constructional column surface, and to the Screw arbor with nut at both-ends head antirust treatment after cut-out.
By such scheme, the step 5）Middle sponge strip width is 18 ~ 22mm.
By such scheme, the step 6）Specifically include：First mounting post inner cross type support, back mounting pole surrounding external mold
Plate, the punching corresponding Screw arbor with nut at both-ends extended position being welded with horizontal tension rib during dispensing；Construct column template and press logical organ timbering installation,
Both sides column template is first installed, draws each column template among logical line installation after calibrated, reinforcing again.
By such scheme, the step 7）Middle tie is buckled including flitch back cord, steel pipe and anti-skidding butterfly, and installation process is specific
For：50mm × 100mm flitch back cord is followed closely on construction column template, spacing 100mm is outer with two along vertical flitch back cord direction
Footpath 48mm wall thickness 3.5mm steel pipe and the anti-skidding butterfly of twice are buckled on Screw arbor with nut at both-ends and tighten fixation, tie vertical interval be 300 ~
500mm。
By such scheme, the step 8）Specifically include：First by the correction of construction mast axis, both sides column template has been reinforced,
Then column template among logical line correction is hung up, column template timing must assure that four sides on the same line, perpendicularity deviation, axle
Line deviation, adjacent two surface difference of height, surface smoothness and cross-sectional internal size are controlled in job specfication tolerance scope
It is interior.
By such scheme, the step 10）Middle Screw arbor with nut at both-ends head antirust treatment is specially floating with cement mortar.
Compared with conventional construction method, beneficial effects of the present invention：
1st, directly the horizontal tension rib of wall and constructional column wall-punching pair-pulling threaded spindle are welded, then with the screw combinations butterfly button
The steel pipe of construction column end wood reinforcement back cord is pinned, the level needed for construction column end reinforcing is provided using the pulling force of horizontal bar
Constraint, fundamentally solve the problems, such as constructional column formwork reinforce must be punched on masonry structure, avoid masonry structure because
The drawbacks of punching of constructional column formwork causes wall integrity and compression strength step-down, make masonry globality and compression strength higher,
Construction is more simple and efficient；
2nd, template construct, installation carry out operation by the quality requirement of plain form, and shuttering supporting uses flitch back cord group
Steel pipe is closed with the reinforcement system of screw rod drawknot, compared with traditional masonry wall sleeve-penetrating drawknot method, simple and easy, the technique is on the spot
Materials, the exposed direct cutting process of screw rod, it is higher to compare the construction method template strength of other building block moulds, more economical.
