Description

Multi-anchor-point corrugated steel fiber for concrete

Technical Field

The utility model relates to a steel fiber technical field especially relates to multi-anchor corrugated steel fiber for concrete.

Background

The steel fiber concrete is a novel multiphase composite material formed by doping short steel fibers which are distributed disorderly into common concrete. The disorderly distributed steel fibers can effectively hinder the expansion of micro cracks and the formation of macro cracks in the concrete, remarkably improve the tensile, bending, impact and fatigue resistance performances of the concrete and have better ductility.

But present concrete still has some drawbacks with many anchor point corrugated steel fiber, its toughness of traditional concrete with many anchor point corrugated steel fiber is better, but it is great to receive the corrosivity in the concrete, receive to overlook for a long time and can lead to steel fiber to lose the effect, can't improve performances such as tensile and bending resistance of concrete, the concrete is when insolateing simultaneously, high temperature transmits on inside steel fiber, can lead to steel fiber strength to reduce, high temperature resistance is relatively poor, for this reason we propose concrete with many anchor point corrugated steel fiber.

Disclosure of Invention

In order to overcome the not enough of prior art, the utility model provides a multi-anchor point corrugated steel fiber for concrete through the high temperature resistant dope layer that sets up, can be by the effective thermal-insulated protection of high temperature resistant dope layer, improves the life of steel fiber main part greatly.

In order to solve the technical problem, the utility model provides a following technical scheme: the multi-anchor corrugated steel fiber for concrete comprises a steel fiber main body, wherein a high-temperature-resistant coating layer is laid on the outer layer of the steel fiber main body, and an anti-corrosion coating layer is laid on the outer layer of the high-temperature-resistant coating layer.

As a preferred technical scheme of the utility model, the skin on two sides about the steel fiber main part is evenly laid to the high temperature resistant dope layer, the thickness of high temperature resistant dope layer sets up to 0.1 mm.

As an optimized technical scheme of the utility model, the outer in the high temperature resistant dope layer is evenly laid to the anticorrosive dope layer, the thickness of anticorrosive dope layer is provided with 0.15 mm.

Compared with the prior art, the utility model discloses the beneficial effect that can reach is:

1. through the high temperature resistant dope layer that sets up, the high temperature resistant dope layer has all been scribbled on the two sides outer wall of steel fibre main part, the high temperature resistant dope layer can bear the temperature more than the degree centigrade for a long time, and can keep certain physicochemical properties, make the special type functional coating that can normally play the effect of protected object in high temperature environment, use borosilicate glass to fill in the resin base member as main filler, can make the steel fibre main part place in the concrete through this device, the steel fibre main part receives high temperature insolateing for a long time, when high temperature transmits to the steel fibre main part, can effectively insulate against heat the protection by the high temperature resistant dope layer, improve the life of steel fibre main part greatly.

2. Through the anticorrosive coating layer that sets up, the anticorrosive coating layer has all been scribbled to the two sides skin of high temperature resistant coating layer, anticorrosive coating layer coating makes it keep apart with surrounding medium on the high temperature resistant coating layer surface, a overburden to control external corrosion, has good electrical insulation and water barrier, has stronger adhesive force with high temperature resistant coating layer surface, can resist chemical destruction and have certain mechanical strength, can make the steel fibre main part can not overlooked easily in the concrete through this device, improve life greatly.
