Description
Technical field
The present invention relates to concrete construction more particularly to the concrete construction methods of overlarge area.
Background technology
In concrete construction field, so-called overlarge area means the concrete walls of the large-scale construction of structures such as basement, pond.
These structures often have overlength, the concrete exterior wall of superelevation, and this kind of concrete walls are also the knot for being easiest to occur quality problems
One of structure.Concrete structure is since the effect of internal and external factor is inevitably present open defect, and construction joint is concrete ground
The most position of the open defect frequencies of occurrences of the concrete walls of overlength superelevation such as lower room, pond.
In view of the above problems, related specifications regulation must be provided with vertical and horizontal construction joint, preferable in the hope of obtaining
Construction quality, but currently also lack effective measures so that during construction, appearance requirement is not achieved.
The content of the invention
The invention of this reality aims to solve the problem that drawbacks described above, provides a kind of concrete secondary formwork construction method of overlarge area.This
Invention can effectively avoid the above problem, and presentation quality is good.
To solve the above problems, a kind of concrete secondary formwork construction method of overlarge area, it includes:
Step 1, the division of concrete walls construction joint；Horizontal, vertical construction joints are set, and segmentation is constructed, and the position of construction joint is stayed
Structure by shear it is smaller and convenient for construction position；
Step 2, the binding of the first construction section reinforcing bar and model sheetinstallat；Before design drawing assembling reinforcement and installation seam
Template；
Step 3, model sheetinstallat at construction joint；Including
At horizontal construction joint, in the horizontal direction in the elongated flitch of template internal setting suitable for reading, flitch uses steel nail and mould
Plate is fixed；
At vertical construction joints, elongated flitch is vertically set in template interior location, flitch uses steel nail and mould
Plate is fixed；
Step 4, concreting；By design requirement casting concrete and vibration compacting；
Step 5, form removal；After the completion of step 4 concreting and maintenance, template and flitch at Demolition Construction seam, reservation are applied
Split bolt at work seam；
Step 6, along the elongated sticking two-faced adhesive tape of the outer edge of first time casting concrete, then after installing the template of the second construction section
The second construction section concrete is poured, so Xun Huan completes entire concrete walls construction.
The concrete secondary formwork construction method of the overlarge area, the step 3In, it is desirable that flitch specification is united
One, bottom line is concordant.
The concrete secondary formwork construction method of the overlarge area, the step 3In, it is desirable that flitch specification is united
One, sideline is vertical, and the vertically arranged dense mesh at construction joint.
Present invention process principle is simple, easy to operation；Formwork is simple, at low cost；Concrete construction joint can be effectively improved
Presentation quality.Material therefor of the present invention can be used in turn；It is suitble to the higher structures of appearance requirements such as dry concrete wall.
Specific embodiment
A kind of concrete secondary formwork construction method of overlarge area, it includes:
1 } according to relevant specification and design requirement, horizontal, vertical construction joints are set to overlength, ultra-high concrete wall construction, point
Stage constructs, and it is smaller and convenient for the position of construction by shearing that the position of construction joint preferably stays in structure.
2）According to the template before design drawing assembling reinforcement and installation seam.At horizontal construction joint, in the horizontal direction
In the flitch that template internal setting suitable for reading is elongated, flitch is fixed using steel nail with template, and flitch uniform specification, bottom line flushes；
At vertical construction joints, elongated flitch is vertically set in template interior location, flitch is fixed using steel nail with template, wood
Square uniform specification, sideline is vertical, and the vertically arranged dense mesh at construction joint.
3）By design requirement casting concrete and vibration compacting after the completion of formwork.First time concreting simultaneously conserves completion
Afterwards, the template and flitch at Demolition Construction seam retains the split bolt at construction joint, along the outer edge of first time casting concrete
Elongated sticking two-faced adhesive tape, then the template of the second construction section is installed.Finally pour next section concrete.
