Aspect, so that assembling is simpler, conveniently, average weight is in 20kg or so, completely by manual handling and assembly, does not need to appoint
The assistance of what mechanical equipment, and system design is simple, and the upper hand speed of worker and 4 reversal rate of template are quickly.Skilled installation
Mountable 20-30 square metres for each person every day of worker, greatly save cost of labor.On the other hand, aluminum alloy pattern plate can be improved cast-in-place mixed
The construction quality of solidifying soil beam section 2 can achieve the effect of clear-water concrete because being improved using aluminum dipping form apparent mass.Further
Aspect, aluminum alloy pattern plate quality is lighter, adapts to lower suspension mechanism and I-shaped bracing members, it is ensured that should be applied to assembled Cast-in-Situ Segment without support
The safety and stability of tool template system.
In conclusion beneficial effects of the present invention are as follows:
1, it reuses often, average use cost is low.A set of Templates specifications construction, which may be reversed, to be used 300 times or more.
The procurement price of a set of template, which shares equally, saves very big cost than conventional template；
2, easy for construction, high-efficient.Simply, conveniently, average weight is in 20kg or so, completely by artificial for template system assembling
It carries and assembled, does not need the assistance of any mechanical equipment, and system design is simple, the upper hand speed of worker and template overturning speed
Degree is quickly.Mountable 20-30 square metres for each person every day of skilled installer, greatly save cost of labor；
3, stability is good, bearing capacity is high, piece is few, and precision is high, and all material is recyclable materials, meets country to building
Build the regulation of project energy-saving and environmental protection, low-carbon, emission reduction.
4, I-shaped bracing members template is hung using screw rod, high-efficient, effect is good, and without support, construction operation space is big for lower part.
Foregoing description is only the description to present pre-ferred embodiments, not to any restriction of the scope of the invention, this hair
Any change, the modification that the those of ordinary skill in bright field does according to the disclosure above content, belong to the protection of claims
Range.
