It's a normal sheet? NO!It's actually a new structural reinforcement material- -carbon fiber sheet.
(1)Control and crack reinforcement of reinforced concrete bridge;
(2) Reinforced concrete bridge plate girder, box girder, T girder bending reinforcement;
(3) Civil buildings, industrial buildings and other buildings, large-span structural beams, plate bending reinforcement, control crack reinforcement;
(4) Long-span reinforced concrete bridge reinforcement, improve the bearing capacity, and is widely used in prestressed or non-prestressed bridge structures.
(1)Light weight, easy operation and do not need large machinery and equipment;
(2)high tensile strength, more than several times of ordinary steel, the elastic modulus is better than steel, with excellent corrosion resistance and earthquake resistance;
(3)High strength, the quality is only 1 / 5 of the steel, has a high toughness, can be coiled, can be supplied in a large length without lap;
(4)The shape of the components is slightly changed, and it does not affect the net space of the structure;
(5)Carbon fiber sheet construction is convenient, no complex operation, the construction quality is easy to ensure.
(1)Construction preparation: positioning and laying according to the design drawings;
(2)Substrate treatment: chisel the concrete surface painting layer to be reinforced, and polish the surface flat;
(3)The concrete surface dust blow clean;
(4)Configuration of glue: according to the weight ratio A: B=3:1, stir component A.B evenly in the packaging bucket;
(5)Apply glue: evenly the glue on the surface of the carbon sheet to avoid bubbles;
(6)Paste the carbon board: paste the carbon sheet on the concrete surface, remove the surrounding overflow of glue and fix it;
(7)Curing and curing: at room temperature, the curing time should not be less than 24 hours.
This is because through the test and calculation of the relevant mechanical properties: a carbon fiber sheet can be equivalent to 4-8 carbon fiber cloth, when the number of carbon fiber cloth paste more than three layers, it needs to be replaced with carbon fiber sheet reinforcement to achieve. Carbon fiber sheet construction is a complex and important project, not only to pay attention to the choice of materials, the control of product quality, but also to the operation of the construction specifications, so as to really make carbon fiber sheet play better in the future engineering practice, more widely used!
