Description
Technical field
The present invention relates to technical field of building construction, in particular to the plastering stone of a kind of steel structure wall with corrosion-inhibiting coating
Cream construction method and steel structure member flameproof protection device.
Background technique
Steel house refers to the residential housing using steel as building bearing beam column, have the characteristics that it is light-weight, with steel knot
Constructing the house weight made is only 1/2 or so of armored concrete house；Also there are the spies such as intensity is high, seismic wind resistance is good
Point.Compared to traditional residential, steel house structural behaviour, using function, design and construction and in terms of have
Greater advantage, developing steel house has the epoch-making significance carried out housing industrialization, improve housing quality, is conducive to China
Building trade technological progress is conducive to pull metallurgy industry domestic demand and promotes the exploitation of energy saving and environment friendly building materials, is that construction industry turns
Type upgrades one of direction.
Containment system is the important system of steel house, it should meet the requirement of lightweight, by there is enough rigidity
And intensity, also to meet the requirement of fire protecting performance, sealing performance, thermal property, sound insulation property, decorative performance, be currently to promote
One of bottleneck of steel house, and the core of research.
Containment system will realize the function of its multiplicity, structurally be necessarily required to the combination of multiple material, plastering gupsum has
Good workability, condensation setting rate is fast, and construction efficiency is high, can obviously reduce wall crazing, the common matter such as hollowing falls off
Measure the generation of common fault.In addition, plastering gupsum has the characteristics that lightweight, fire prevention, insulation, it can play and adjust indoor humidity, change
The effect of kind living environment, is the important component in containment system.Compared to the plastering sand such as conventional cement base plastering mortar
Pulp material, plastering gupsum have many advantages, such as energy conservation and environmental protection, durable, are not pulverized easily, are not easy hollowing and cracking, be it is a kind of more
Ideal wall plastering material.
Compared to concrete, block wall, the consistency of the steel structure surface with corrosion-inhibiting coating wants high more, and and its light
It is clean, hardly absorb water, the mechanical snap power that can be provided is extremely weak；Therefore, between steel construction and plastering gupsum with corrosion-inhibiting coating
Tensile bond strength is lower.And due to the particularity of the steel structure surface with corrosion-inhibiting coating, existing concrete, block wall plastering
The construction method of gypsum is simultaneously not suitable for, the interfacial agents of the enhancing wall and plastering gupsum adhesion strength performance that use in construction
Not applicable steel structure wall.In addition, since plastering gupsum is different from the composition of cement base plastering mortar, surface texture and performance,
Construction method for steel structure wall and cement base plastering mortar is also not particularly suited for plastering gupsum, the boundary used in construction
Face agent is not suitable for plastering gupsum yet.Therefore, construction method in the prior art not can solve the steel construction with corrosion-inhibiting coating
The problem of adhesion strength between metope and plastering gupsum, its practical application is limited to significantly.
Summary of the invention
In view of this, the purpose of the present invention is to provide a kind of constructions of the plastering gupsum of steel structure wall with corrosion-inhibiting coating
Method and steel structure member flameproof protection device.It can be improved band corrosion-inhibiting coating steel construction using construction method of the invention and smear
Tensile bond strength between grey gypsum.
The present invention provides a kind of plastering gupsum construction methods of steel structure wall with corrosion-inhibiting coating, including following step
It is rapid:
A) interfacial emulsion is coated in the steel structure wall with corrosion-inhibiting coating, forms emulsion layer；
The interfacial emulsion is the lotion that organic polymeric emulsions and water are mixed to form；
The organic polymeric emulsions are ethene-vinyl acetate copolymer emulsion and/or acrylic emulsion；
B) after emulsion layer film forming, plastering gupsum is coated.
Preferably, the solid content of the interfacial emulsion is 10%~50%.
Preferably, the ethene-vinyl acetate copolymer emulsion is selected from ethylene-vinegar of the vinyl acetate content 70%~95%
Sour ethylene copolymerization emulsions；
The acrylic emulsion is styrene-acrylic emulsion and/or pure acrylic emulsion.
Preferably, the plastering gupsum includes the component of following mass parts:
Preferably, the anticorrosive paint for forming the corrosion-inhibiting coating is epoxy coating.
The present invention also provides a kind of steel structure member flameproof protection devices, comprising:
Steel structure member substrate 1；
It is compound in the interface agent layer 2 of one side surface of steel structure member substrate；
It is compound in the gypsum base fire prevention pulp layer 3 on 2 surface of interface agent layer.
Preferably, the interface agent layer 2 is organic emulsion film layer；
Organic emulsion in the organic emulsion film layer is ethene-vinyl acetate copolymer emulsion and/or acrylic emulsion.
Preferably, the ethylene-vinyl acetate copolymer emulsion is ethylene-vinegar of the vinyl acetate content 70%~95%
Sour ethylene copolymerization emulsions；
The acrylic emulsion film layer is styrene-acrylic emulsion and/or pure acrylic emulsion.
Preferably, it is provided with the steel mesh 5 parallel with interface agent layer 2 in the gypsum base fire prevention pulp layer 3, passes through steel mesh 5
It is two layers that gypsum base fire prevention pulp layer 3, which is divided,；
The steel mesh 5 is connect by fixing piece 4 with the steel structure member substrate 1.
Preferably, the flameproof protection device includes several fixing pieces 4；
