Preparation method of section steel ultra-light concrete member

Abstract

The invention relates to a profile steel ultra-light concrete member and a preparation method thereof. The profile steel ultra-light concrete member comprises a profile steel skeleton, a light core material and an ultra-light heat-insulating concrete layer, wherein the light core material is arranged in an inner cavity of the profile steel skeleton and used for forming holes or cavities; the outer surface of the profile steel skeleton is coated with the ultra-light heat-insulating concrete layer; and a cavity between the profile steel skeleton and the light core material is filled with the ultra-light heat-insulating concrete layer. According to the member, the fire-proof and corrosion-prevention performance of a steel structure is improved through ultra-light heat-insulating cement concrete with a porous polymer serving as a lightweight aggregate; holes and cavities are formed by using the light core material, so that the weight of the member itself is reduced; not only are production, transportation and construction facilitated, but also the weight of a building or member itself is reduced; the anti-seismic property is improved, and at the same time, requirements of using functions such as fire prevention, thermal insulation, heat preservation, sound insulation, water resistance, anti-permeability and the like are met; and a product can be produced conveniently and rapidly by using the preparation method, the process is simple, the manufacturing cost is low as well, and mass production can be realized.

Description

technical field [0001] The invention relates to the field of construction, in particular to a method for preparing a section steel ultra-light concrete component. Background technique [0002] The temporary light board houses in the existing fully assembled houses mostly use expanded polystyrene boards with metal panels, which not only has serious fire hazards, but also has poor heat and sound insulation effects, short service life, and difficult to perfect use functions. [0003] The existing permanent fully assembled building components use less lightweight materials, which will not only lead to a large overall weight of the components, but also a large amount of handling work during production and construction, strict requirements for lifting and transporting machines, and high construction costs. When the temperature reaches 600 degrees, the strength begins to decline, and when the temperature reaches 600 degrees, it will lose its bearing capacity, and its fire performan...

[0002] The temporary light board houses in the existing fully assembled houses mostly use expanded polystyrene boards with metal panels, which not only has serious fire hazards, but also has poor heat and sound insulation effects, short service life, and difficult to perfect the use function

[0003] The existing permanent fully assembled building components use less lightweight materials, which will not only lead to a large overall weight of the components, but also a large amount of handling work during production and construction, strict requirements for lifting and transporting machines, and high construction costs. The strength begins to decline when the temperature reaches 600 degrees, and it will lose its bearing capacity when the temperature reaches 600 degrees, and the fire performance is poor.

At present, although the fireproof layer set on the steel member can play a certain role in fireproofing, the strength of the fireproof layer is poor. In order to ensure that it will not be damaged during transportation, it needs to be constructed on site to form a fireproof layer. In addition, the fireproof layer will be burned after a fire occurs. , need to reinstall
