Fiber sheet plate and usage

Abstract

This invention is a fibre sheet and its use. It contains: carbon fibre, aromatic nylon fibre or high strength glass fibre. After to weave them, soak them into soaking materials. This soaking liquid is composed with: liquid epoxy resin, solid epoxy resin and polyamide, the ratio of their weight is 0.8-1.3: 0.8-1.3: 0.8-1.3. This fibre sheet use for to reinforce the cement constructors. It contains: The surface treatment of cement; to provide the material for leveling. To glue the epoxy resin in the structural members they have crack or split. To compound the sticker and smear the glue on the fibre sheet surface.

Description

technical field [0001] The invention relates to civil engineering, in particular to a reinforced, anti-seismic and anti-shock fiber sheet used for concrete buildings such as bridges, tunnels and houses. [0002] The invention also relates to a method for reinforcing, anti-shock, and anti-shock of the fiber thin plate used for concrete buildings such as bridges, tunnels, and houses. Background technique [0003] In order to enhance or restore the use function of concrete buildings such as bridges, tunnels and houses in service, as well as improve the bearing capacity, earthquake resistance and shockproof functions of newly built bridges, tunnels and houses and other buildings, the existing technology mainly uses steel plates, carbon fiber cloth, carbon fiber The board achieves its purpose by pasting and strengthening. [0004] The construction process of using steel plates for reinforcement includes: [0005] - pre-cut steel plates; [0006] ...

AI Technical Summary

Problems solved by technology

[0011] The use of steel plates for reinforcement has the following problems: (1) heavy steel plates; (2) poor corrosion resistance; (3) high requirements for the flatness of the pasted surface; (4) high construction costs; (5) high maintenance costs; (6) The steel plate needs to be prefabricated in advance, and its size is limited; (7) The equipment requirements are complex

[0020] The following problems exist in the use of carbon fiber cloth reinforcement: (1) high material cost; (2) poor shear resistance; (3) generally need to paste more than two layers of carbon fiber cloth, which increases the interface of the structure, resulting in a decrease in its mechanical properties; (4) The amount of glue is large, and the impregnation and adhesive glue are mainly imported, which is expensive

[0028] There are the following problems in the use of carbon fiber plate reinforcement: (1) high material cost; (2) poor shear resistance, which cannot be used for shear reinforcement; (3) higher requirements for the flatness of the pasting surface; (4) the amount of glue used is large, Moreover, the adhesive is mainly imported, which is expensive; (4) Carbon fiber panels need to be prefabricated in advance, with few specifications and models, and there are restrictions on their size

[0033] 2) For reinforcement projects with high strength requirements for components, 2 to 3 layers or even more layers of carbon fiber cloth must be pasted, resulting in an increase in the interface of the structure, a decrease in reinforcement efficiency, an increase in engineering volume, and an increase in cost;

[0034] 3) When using a single-layer carbon fiber board for reinforcement, since the thickness of the fiber board is generally 1 to 2 mm, it is hard and straight, and cannot be bent, so the construction is difficult and the scope of use is also greatly restricted;

[0035] 4) There is no uniform inspection method and standard for the mechanical properties of fiber cloth or fiberboard;

[0036] 5) The influence of fatigue and the influence of cracks on the strength of components have not been fully considered in the design standards, and the method of optimal design has not been adopted;

[0037] 6) Domestic carbon fiber cloth, due to the limitations of raw material properties, etc., its mechanical properties still need to be improved
