Description
Technical field
The utility model is related to a kind of fabricated sub- walls of lightweight concrete.
Background technology
It is pointed out in " General Office of the State Council is about the instruction for greatly developing assembled architecture ", implements the 18 of party comprehensively
It is big and 18 three in, in four, the fifth plenary session and central urbanization working conference, central urban work conference key agreement, conscientiously
The CPC Central Committee and the State Council's decision and deployment are implemented, according to " five in one " total arrangement and " four comprehensively " strategic, are firmly established
With carry out innovation, coordination, green, opening, shared idea of development, according to be applicable in, economy, safety, green, beauty are wanted
It asks, pushes mode of construction innovation, greatly develop assembly concrete building and steel building, assembled architecture is continuously improved and exists
Ratio in new building.Adhere to standardized designs, factorial praluction, prefabricated construction, integrated finishing, information system management,
Intelligent Application, improves technical level and construction quality, promotes building industry transition and upgrade.
Traditional wall construction technique generally uses common brick, Dinas brickes, air-entrained concrete building block etc. to be built by laying bricks or stones.These
There are many deficiencies in common materials for wall：
(1) common brick refers to solid clay brick, and because it destroys arable land in process of production, waste of resource pollutes environment, at present state
Family takes the measure forbidden to protect farmland and environment；
(2) Dinas brickes is to allow to mix pigment and additive using sand and lime as primary raw material, is prepared through blank, compacting
It is molded, through common Dinas brickes made of autoclave curing, sanded brick surfacing is smooth, poor with the bonding of mortar, be easy to cause
Gaul cracks.Absorption speed is slow, blocked up coat of plaster, be easy to cause mortar trickling cracking.It is strong with mortar bonding after building by laying bricks or stones
Degree is not high, causes masonry shear strength relatively low, influences the use in earthquake protection area to a certain extent.
(3) air-entrained concrete building block, be using calcareous material (cement or lime), siliceous material (sand or flyash etc.) and
Foaming agent (generally use aluminium powder) generates silicate Tuo Bomolai through adding water to be chemically reacted under high-temperature steam curing hydrothermal condition
Stone etc., forms the lightweight entirety with uniform gas cell distribution, and porosity is up to 70%~80%.Since porosity is very big, make it
Effective loaded area is reduced, therefore intensity is generally all relatively low.Due to there is no skeleton soil in air entrained concrete, hydrated product
Crystallization degree is higher, and plastic deformation is small, therefore without apparent crackle before stress destruction, once it is cracked, it will collapse immediately
Destruction is split, this is different from the property of normal concrete, therefore the elasticity modulus of air entrained concrete is less than normal concrete.Aerating is mixed
Solidifying soil product is light material, is used as materials for wall, the quality of unit area is smaller, therefore its sound-insulation capability is low.
, there is technique backwardness in above-mentioned three kinds common material masonry panels, need largely manually to carry out removing brick, slurrying,
Build by laying bricks or stones, brooming, plaster etc., process is more, and mechanization degree is low, inefficiency, in the case where craftsmanship is horizontal irregular,
Construction quality is difficult to be protected, and faces working at height danger again.To solve the above-mentioned problems, it is proposed that a kind of assembled
Lightweight concrete wall construction technology.
