Description
Technical field
The invention belongs to building walling technical field, be specifically related to one
fully-prefabricated assembled enclosure wall.
Background technology
As everyone knows, traditional building enclosing wall mostly is the form such as entity enclosure wall, transmission enclosure wall.Entity enclosure wall has placed rockfill, cemented rock, grouted brick body and concrete block etc.Transmission enclosure wall then takes masonry and fence to be combined to form.Its construction method mostly is on-the-spot masonry method, through on-the-spot line setting, the excavation foundation earthwork, build blinding concrete, installation foundation template, colligation reinforcement foundation, pouring base concrete, build (or building) column or body of wall by laying bricks or stones, fence is installed, covers with paint, lacquer, colour wash, etc. exterior wall, all multiple operation such as to inspect for acceptance.Its shortcoming is that interim occupation of land is many, working procedure is many, construction period is long, apparent mass is poor, generation waste material is many, contaminated environment is large, and the body of wall basis on unfavorable foundation easily produces differential settlement, thus cause wall body slit, and even topple, its poor seismic behavior.
beijing Hong Tangchuan generation Science and Technology Ltd.cooperate with Japanese Waseda University and Japanese Ye Ze Co., Ltd., bring AS assembled architecture system into China.For many years, the said firm successively under Jiangsu Ling Kou, Datong, Fujian the ground such as cloud, Hebei Xingtang, Guangxi emerald built up
partial precast Assembled enclosing wall.This partial precast Assembled enclosing wall,
the basis of its whole enclosure wall and column are on-the-spot shuttering and build shaping,only has curtain wall penel and bear down on one part and upright post cap are prefabrication and assembly constructions.
beiJing TaiKeLi High and New Technology Co., Ltdresearch and develop and produce
cement based Assembled enclosing wall, beared down on one formed by basis (cup-shaped and bar shaped), column (H type and U-shaped), curtain wall penel (width modulus 600mm, 500mm, 300mm), cap, enclosure wall.Curtain wall penel is the high-strength light cement based extrusion moulding curtain wall penel adopting equipment Imported From German EMH Company to produce, this product thoroughly solves the shortcomings such as the intensity of foamed concrete ALC plate is low and regularity is poor, it has, and body of wall appearance effect is good, service life long (30-50), maintenance cost low (substantially maintenance-free), the distinguishing feature such as construction period short (saving the duration 50% compared with traditional masonry enclosure wall), anti-seismic performance be strong.This cement based Assembled enclosing wall is at project applications such as Ulan hada-root of kudzu vine mausoleum 66KV transformer station, Changchun Can Hua 66KV transformer station, Western Hills garden, Zhangjiakou 110KV transformer stations.But,
the construction of this cement based Assembled enclosing wall still needs earth excavationjust can bury cup-shaped or strip foundation prefabricated section part underground.
On April 24th, 2013, Patent Office of State Intellectual Property Office discloses the Assembled enclosing wall (application number CN201310037917.4) of Guo Xueming, Li Qingshan application of extensive region, Shenyang million modern architecture industrial park Co., Ltd.A kind of Assembled enclosing wall of this disclosure of the invention, primarily of the component composition of cylinder and wallboard, cylinder and wall plate member site assembly form enclosure wall.Component is mould molding in the factory, then transports to job site assembling, convenient and quick construction, and not by the restriction in season.The Assembled enclosing wall of this invention adopts different combinations to form the enclosure wall of various fancy.Component, in plant produced, is then transported to job site assembling, Assembling simple and fast, is shortened construction period.Product waste material is few, precision is high, pattern is many.Produce and be not subject to seasonal restrictions, winter also can produce, and solves winter construction problem.There is a certain amount of deformability between assembling cylinder and wallboard, this addresses the problem the problem of body of wall due to temperature generation crack.But, this Assembled enclosing wall of this disclosure of the invention,
its basis is still the strip foundation of cast-in-situ concrete, therefore, this Assembled enclosing wall
also partial precast Assembled enclosing wall is belonged to, neither prefabricated, complete fabricated enclosure wall entirely.
Prestressed concrete pipe pile is widely used in the Foundation Design of modern architecture, especially for the building built on unstable soil layer or Soft Soil Layer and infrastructure projects, prestressed concrete pipe pile is by being passed on the stable bearing stratum of underground by the load of building, thus support of buildings, guarantee its safety and stablization.
Summary of the invention
