Description
Technical field:
The invention belongs to technical field of building construction more particularly to a kind of L-type open type permanent beam template, specifically one
Kind is mainly used for the high durable permanent beam gang forms of L-type of hydro-structure, port sea structure, industry and civil buildings etc., is pouring
Build the stage uses as template, and the protective layer of beam is also served as after pouring molding and participates in arrangement works.
Background technique:
In the realm of building construction, pouring for reinforced beam often relies on plank sheathing or steel form.Plank sheathing low cost,
It from heavy and light, is easily installed and constructs, but its turnover rate is low, the service life is short, and is difficult to recycling and reusing, brings burden to environment.Steel
Form cycling rate is high, and concrete formation quality is high, and steel are easily recycled, but it from great, cost is high, this is greatly
Constrain its application in structure of reinforced concrete.
Normal concrete have poor toughness, tensile strength is low, shock resistance is weak, it is easy to crack and cracking after crack be difficult to control
The inborn Brittleness such as system.Moreover, always work with cracking can draw concrete structure if the control of fracture width is ineffective
The endurance issues for playing structure, become security risk.For being in the structure of marine environment, severe cold area, harsh environment makes
Durability becomes the factor that mainly considers, and the cracking of concrete can greatly reduce the endurance quality of structure, and crack can be at
For extraneous hazardous medium (such as villaumite, sulfate, CO2Deng) channel of structure is penetrated into, and then lead to steel bar corrosion, coagulation soil blister
It splits, needs regular maintenance, substantially increase the life cycle cost of structure.
(Engineered Cementitious Composites is referred to as high ductility fiber reinforced cement-based composite material
ECC) it is a kind of novel high-performance civil engineering work material, there is pseudo- strain hardening characteristic and multiple cracking to carry out mechanism, in list
Under the effect of axis tensile load, limit tensile strain can reach about 300 times of 3%-6%(concrete), and it is maximum under limiting condition
Fracture width is only 100 μm or so, can effectively prevent the infiltration of hazardous medium, slows down the corrosion of reinforcing bar, reduce corrosion cracking and
A possibility that concrete cover peels off, improves the durability of structure.
Usually there is big, transport difficult of occupied space etc. in current existing reinforced beam ECC monoblock type permanent template
Pain spot, transportation cost with higher limit the promotion and application of ECC permanent template.
