Close, can repeat to be used in turn in multiple engineerings, the number of turnover is more, and cost recovery is high, and amortization charge is few, overall economic efficiency
Significantly.
（5）In light weight, small volume, is readily transported.Square steel keel small volume, in light weight, most long 4.2 meters of weight of component are not
More than 13kg, most of is 2.7m, no more than 8kg.Only need to set below elevating capacity 5t tower crane to complete mould in construction
The vertical transport of plate, mechanical one-shift expense 25% can be saved compared with Large Formwork Technology, short distance, long-distance transport are all convenient, can carry out
Strange land engineering is used in turn, and overall economic efficiency is notable.Zinc-plated square steel replaces flitch, and the low value easy consumption product in engineering are reformed
For circulation material, square steel keel can be recycled in multiple engineering constructions, can be used in turn more than 300 times, amortization charge is low.
（6）It is small to take construction site, is had a clear superiority for the narrow and small project in construction site.
（7）Component standardization, modularization, annex is simple, strong applicability.Square steel uniform specification, connected using sizing auxiliary,
Simple and reliable, installation rate is fast.Shear wall construction is not only applicable to, applies also for frame column, beam, plate construction.Standardization, mould
The worker's construction of numberization specification, while construction quality is improved, ensure that the clean and tidy of job site, and base is laid for civilized construction
Plinth.
（8）Energy-conserving and environment-protective.Timber is saved, protects the limited forest reserves；Saving steel, protect non-renewable resources；Section
About plastics, construction quality is ensured, ensure health of masses；It is not required to cut the lumps of wood, without wood chip, mitigates atmosphere pollution；Save work
Power, improve operating efficiency；Square steel can be recycled, and can be regenerated with useless.
3. the scope of application

Wall column line setting → nail pressure foot → wall column formwork installation.
2 key points for operation
Snap the line releases wall column position line on floor after lower floor's beam slab concreting 12 hours, then installs wall column presser feet
Plate, then wall column assembled good plank sheathing in advance is installed（Shear wall sets the splicing lumps of wood, pillar along wall length direction interval 1500mm
A piece jigsaw lumps of wood is respectively then set at the both ends of every side, the jigsaw lumps of wood is 45*45mm）, square steel uses 40*40*2.5 square steel@
250mm, template is using the thick two-sided overlay film multi-layer sheet of wood of 15mm.
6. quality control
6.1 perform standard
《Building construction formwork technical specification of security》JGJ 162-2008
《Concrete structure engineering construction quality accident specification》GB50204-2015
Engineering technology, quality guarantee data are accomplished synchronous with entity, timely, accurate, complete, and meet specification and evaluation criteria will
Ask.
6.2 quality control
To template and its support system requirement：
Ensure structure, component each several part geomery it is accurate；
Must have enough intensity, rigidity and stability；
Form joint is tight, must not spillage；
It is easy to the peace of template to tear open；
To cast-in-situ steel reinforced concrete beam of the span not less than 4 meters, plate, its template should be by design requirement arch camber；When design nothing
During specific requirement, springing height is preferably 1 ‰~the 3 ‰ of span；
The contact surface full coat interleaving agent of template and concrete, plank sheathing is soaked with water before casting concrete, but there must not be product
Water；
In order to improve work efficiency, ensure quality, template should number positioning when reusing, clean out mortar in template, brush
Interleaving agent, concrete is reached not arrisdefect, do not peel, any surface finish.
Processing post, beam, the template assembly of plate junction meticulously, accomplish stabilization, firmly, not spillage.
The built-in fitting and reserving hole being fixed in template must not be omitted, and installing must firmly, and position is accurate, and it allows
Deviation all should be controlled in permissible value.
Test block is carried out in construction at the construction field (site), with structural concrete cured under same condition, tests determined specific form removal
Time；
The template and support that following one layer is should ensure that during the Beam-Slab Construction of upper strata are not removed.
7. safety measure
The electric wire set up in 7.1 templates and the electric tool used, should be using 36v low-tension supply or using special electronic box
With earth leakage protective device.
During 7.2 work high above the ground, various accessories should be placed in tool box or kit bag, must not be dropped.Forbid to be placed on template or
On scaffold.
7.3 work high above the ground personnel No Climbing template or scaffold etc. up and down, also must not high-level wall top, isolated beam and
Its template etc. is walked above.
Reserving hole of 7.4 templates etc., setting safety net should be capped.
During 7.5 assembly and disassembly template, answer someone to scoop out up and down, with tearing open with transporting, and movable part fixation should be forbidden heap
It is placed on scaffold and leaves.
During 7.6 assembly and disassembly template, it is necessary to using firm ascending tool, highly more than 3.5m when, it is necessary to set up scaffold.Dress
When tearing construction open, in addition to operator, must not stand people below.During work high above the ground, operating personnel should hang up safety belt.
When 7.7 installation walls, column template, fixation should be supported at any time, prevents from toppling.
The installation of 7.8 pre-splicing deckings, answers side in place, side correction, while installing connector, and adds temporary support and consolidates.
During the vertical handling of 7.9 pre-splicing deckings, more than two suspension centres should be taken, should set four suspension centres during horizontal handling.
During 7.10 dismounting bearing form, temporary support should be first set up, prevents overall suddenly collapse.
8. environmental practice
8.1 march into the arena before carry out employee's environmental protection education, improve employee's environmental consciousness.
8.2 strengthen machine management, improve construction technology, reduce the noise in work progress.Noise measarement meets national mark
It is accurate《Construction site noise level limit》.
8.3 disposal that are waste and old, eliminating template：Scene sets recovery place respectively by damaged template degree and size, realizes
Classification Management, and make mark.Phenomenon is arbitrarily stacked without rubbish in job site.Discarded template timing is single by timber recovery in useless 1 day
Position cleaning, damage it is lighter or it is rotten while big-size formwork will per while cut off 150mm, to be used in turn again or for secondary structure
Fragmentary small members use.
The all high-quality steel of square steel keel template system make, the minimum 2.5mm of thickness, therefore can be used in turn repeatedly
300 times, and traditional lumps of wood keel mode consumes billion cubic meter on timber every year in construction, thus with traditional lumps of wood support phase
Than saving 70% cost.Big punching block purchase cost is high, and second institutional reform expense is high, and construction speed is slow, can be saved compared with large steel moulding plate
Save 50% cost.Timber is saved, is protected forest resources, to give grandson to leave a piece of green.
9. Economic and Efficiency Analysis
My project is carried out statistical summaries to the information fed back to and drawn by Tracking investigation square steel keel template system, with
10000 ㎡ are that unit is calculated, and the saving of flat cost and overhead cost is as shown in the table：
Specific case used herein is set forth to principle of the present utility model and embodiment, above example
Explanation be only intended to help and understand method and its core concept of the present utility model.It should be pointed out that for the art
For those of ordinary skill, on the premise of the utility model principle is not departed from, some change can also be carried out to the utility model
Enter and modify, these are improved and modification is also fallen into the protection domain of the utility model claims.
