Description
Technical field
The present invention relates to a kind of hollow floor, more particularly, to a kind of hollow floor obturator and preparation method thereof, belong to
Hollow floor building field.
Background technology
Hollow floor is due to saving construction material, the deadweight of mitigation superstructure, convenient and use certain material energy of constructing
Enough be incubated, heat-insulated, sound insulation, energy-conservation and antidetonation and other effects, thus be widely used in cast-in-situ steel reinforced concrete or prestress steel
In superstructure, roof system, wall, sole plate and the bridge of reinforced concrete.Obturator product is needed in hollow floor, it is multi-purpose at present
The polystyrene foam plastics obturator of Surface coating glass fiber reinforced cement enhancement layer.According to traditional portland sand
When starching enhancement layer, fiberglass gridding cloth is corroded by high pH value cement in the enhancement layer for a long time, reduces tensile strength, loses
The enhancing to binder materials and the protective effect to polystyrene obturator are gone, the durable of hollow floor obturator is leveraged
Performance；According to low alkalinity magnesia oxychloride cement mortar enhancement layer when, it is cast-in-place mixed that chlorion therein can corrode hollow floor again
Reinforcing bar in solidifying soil.
In the prior art, EPS main components are mainly fireproof polystyrene for main body：Paste alkali resistant glass fibre open weave cloth,
It is subject to special bonding external protection to be composited, it resists cold not by temperature change, heat-resisting；Do not make moist moisture marquis and acid rain
Influence, is gradually promoted the use of in building field；It mainly has the following advantages that：
First, it is lightweight.EPS lines aggregates are poly-Stupid ethene, its finished weight is approximately 1/6 or so of GRC decorative threads, and a people is
It can arbitrarily move, construct.
2nd, firm pasting.EPS decorative threads are mainly usePolymer mortarBonded with metope, polymer mortar be by
Organic gel is added to the stirring of inorganic material cement mortar and is made, and service life is long, is firmly bonded, and has had national standard and rule
Model, and it is proved to be safe and reliable in a large amount of engineer applieds, thus avoid because using the construction of crab-bolt fixed form and crab-bolt
The hidden danger of corrosion, is also thoroughly solvedExternal wall outer insulationCold,Heat bridgeThe problem of.
3rd, moulding is arbitrarily processed.EPS lines use Computer Design moulding, and surface trimming produces short time limit.
4th, it is easy for installation.Using special binding material and method, a people just can especially measure big with installation
Lines engineering, only need to bond installation.
5th, it is seamless between lines.EPS mouldingsBetween used and bond identical gap material for repairing with metope, gap is complete
Portion disappears, and is also not in crack in use afterwards.
