In the construction method of prefabricated house of the present invention, most work prefabricated completion in factory, material
Waste is greatly decreased, and the actual amount of raw material is also greatly reduced because the sectional area of component is smaller, really realizes resource section
About utilize.In plant produced, its reliable in quality, precision is substantially improved component, and production efficiency is greatly improved, the work of building-site
Amount is greatly decreased so that the safe, civilized of site operation, health, quality are able to significantly take on a new look, and construction cost is more economical.
The present invention uses RPC 7, the prefabricated post 3 of outsourcing foam cement 8 and the precast beam of interior raising intensity
5.Due to the high intensity and toughness of RPC 7（Its intensity is generally in 200MPa~800MPa）, with common steel knot
Structure is compared, and beam column of the invention can be greatly decreased steel using amount, can significantly reduce cost；Compared with reinforced concrete structure, this
The structure of invention is lighter and handier, and stress is good, under RPC 7 is because of the hoop constraint in rectangular steel pipe, and carries
Its anti-bending strength and compression strength are risen, rectangular steel pipe is also substantially improved because being filled by the RPC 7 of high intensity
Its rigidity and axial direction, lateral anti-pressure ability, thus, the sectional area of beam column is significantly reduced, and so-called " fat beams and columns " problem is obtained
To solve, the requirement of " the thin wall of girder buttress shaft " is really achieved, it is possible to increase the usable floor area in house, also make the interior space regular,
Can also reduce cost of a building simultaneously.
In addition, the thermal conductivity of RPC 7 is good, with specific heat capacity higher, and foam cement 8 be it is good every
Hot material, so, when a fire, rectangular steel pipe outsourcing foam cement 8 can effectively completely cut off heat invasion and attack steel, for part
The heat of steel is had been enter into, the RPC 7 of inside filling can largely disperse and share again so that this
Invention has fabulous fire protecting performance.
Moreover, the foam cement being wrapped in outside precast beam rectangular steel pipe 4 and prefabricated post rectangular steel pipe 30 can prevent precast beam
Rectangular steel pipe 4 and prefabricated post rectangular steel pipe 30 are corroded, and can play preferable antisepsis, therefore the foam cement 8 of outsourcing makes
The Anticorrosion for obtaining steel is also addressed.
Calculating shows, due to reducing the cost saved with material amount in the present invention, can not only offset because reactive powder is mixed
The expensive cost increase brought of folk prescription of solidifying soil 7, and also obvious surplus.Moreover, RPC 7 has
High-durability, the life-span of building is significantly extended.Therefore, the present invention has good Technical Economy.
Those skilled in the art can carry out various modifications and variations to the embodiment of the present invention, if these modifications and change
Within the scope of the claims in the present invention and its equivalent technologies, then these modifications and modification are also in protection scope of the present invention for type
Within.
In the prior art that the content not described in detail in specification is known to the skilled person.
