Description

A kind of precast concrete external wall panel
Technical field
This utility model is related to assembled architecture outer wall body technique field, more particularly, to a kind of precast concrete exterior wall Plate.
Background technology
Precast concrete external wall panel is to be processed into mix for the reinforcement that building is assembled in precast plant (field) or construction site Concrete board type component, abbreviation wallboard or wallboard.Assembled large panel building is built using precast concrete wall panel, factory can be improved Change, mechanized construction degree, reduce situ wet operation, save live recruitment, overcome seasonal effect, shorten the construction cycle.
At present, precast concrete external wall panel includes three kinds of facade plate, gable board and eaves wallboard;Facade plate is certainly Load-bearing wall panel, gable board are load-bearing wall panel with eaves wallboard.Side fascia except should have sound insulation with fireproof function in addition to, should also with every Hot insulation, impervious, freeze thawing resistance, anti-carbonization etc. act on and meet the requirement of art of architecture decoration, and Side fascia can be single with light-weight aggregate Material is made, and composite (structure sheaf, heat insulation layer and finish coat) may also be employed and makes.
At present, the production technology of precast concrete external wall panel is mostly:It is processed in the mould made prefabricated mixed Solidifying cob wall plate, can be divided into cleaning template, separant coating, cloth muscle in mould, concreting, vibration moulding, maintenance, form removal, inspection, The operation such as finished product stacking and transport.Its method has produced by plane moulding and formwork erection to produce two kinds.It is divided into pedestal method, flat-die by production technology Unit flowing water method, flat-die transmitting stream water law and battery mould or four kinds of paired formwork erection method.
As national energy-saving reduces discharging the reinforcement of dynamics, design standard for energy efficiency of buildings more and more higher;Energy Saving Design of Residential Buildings Standard requires energy-conservation 75%, or even requires that building reaches super low energy consumption standard.Reach above-mentioned energy conservation standard, the heat transfer system of exterior wall Number requires lower, and corresponding wall heat insulation material is also thicker, design to building, builds and using making troubles.
Ultra-thin vacuum heat-insulating plate is extremely low due to heat transfer coefficient, the 1/6-1/10 of only conventional insulation material, and fire-protection rating is A1 levels can meet Building Fire Protection requirement, but in building heat preservation using exterior wall thin-coat plaster form using there is construction precision requirement Height, weather resistance are low, the problems such as high labor intensive.Inside and outside two layer concrete and intermediate insulating layer are connected additionally by connector Together, metal connecting piece can make Side fascia there is local heat bridge phenomenon, and building integral heat insulation effect is undesirable.
Therefore, how to provide it is a kind of have that heat-insulating property is more preferable, weatherability more preferably, more reasonable structure, and later stage assembling The precast concrete external wall panel of construction more simple and efficient is the technical problem of those skilled in the art's urgent need to resolve.
