Description
Technical field
The utility model is related to building template technical field, more particularly to a kind of back cord structure for building template.
Background technology
Building template is the important tool of concrete structure engineering construction.In Cast-in-situ Concrete Structural Engineering, form fixer
Journey typically constitutes from the 20%~30% of concrete structure engineering cost, accounts for the 30%~40% of the engineering amount of labour used, accounts for the 50% of the duration
Left and right.Mould plate technique directly affects the quality, cost and benefit of engineering construction, therefore it is push Building technology progress one
Important content.
At present, the former material of building template is mainly the following：
First, plank sheathing, relatively common is poplar template and pine template, and this template is in contrast relatively lighter, cost
It is slightly lower, but durability is bad, and recycling rate of waterused is very low.
2nd, steel form, intensity is very big, but preponderance, reuses, and cost is high.
3rd, plastic formwork, not afraid of water, cost is relatively low, durable, but insufficient strength.
In order to solve previous conventional template there are the defects of, building template industry further has developed aluminum alloy pattern plate.
