Description
Technical field
The invention belongs to building walling technical field, be specifically related to a kind of fully-prefabricated assembled enclosure wall。
Background technology
It is known that traditional building enclosing wall mostly is the form such as entity enclosure wall, transmission enclosure wall。Entity enclosure wall has placed rockfill, cemented rock, grouts brick body and concrete segment etc.。Transmission enclosure wall then takes masonry to be formed with fence combination。Its construction method mostly is on-the-spot masonry method, on-the-spot line setting, the excavation foundation earthwork will be passed through, 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 inspect for acceptance。Its shortcoming is that interim occupation of land is many, working procedure is many, construction period length, apparent mass are poor, generation waste material is many, contaminated environment big, and the body of wall basis on unfavorable foundation easily produces differential settlement, thus causing wall body slit, even topples, its poor seismic behavior。
Beijing Hong Tangchuan generation Science and Technology Ltd. cooperates with Waseda University of Japan and Ye Ze Co., Ltd. of Japan, brings 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 Aeschna melanictera 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 molding, only curtain wall penel and bear down on one part and upright post cap is prefabrication and assembly construction。
BeiJing TaiKeLi High and New Technology Co., Ltd's research and development and the cement based Assembled enclosing wall produced, 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, the distinguishing features such as this product thoroughly solves the shortcomings such as the intensity of foamed concrete ALC plate is low and regularity is poor, and it has, and body of wall appearance is good, service life length (30-50), maintenance cost low (substantially freedom from repairs), construction period short (saving the duration 50% compared with tradition masonry enclosure wall), anti-seismic performance are strong。This cement based Assembled enclosing wall is at project applications such as Ulan hada-Radix Puerariae 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 remains a need for earth excavation and just can bury cup-shaped or strip footing 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 company limited。A kind of Assembled enclosing wall of this disclosure of the invention, is mainly made up of the component of cylinder and wallboard, and cylinder and wall plate member assembled in situ constitute enclosure wall。Component is mould molding in the factory, then transports to job site and assembles, and convenient and quick construction, unlimited by the restriction in season。The Assembled enclosing wall of this invention adopts different compound modes to form the enclosure wall of various fancy。Component, in plant produced, is then transported to job site and is assembled, and Assembling simple and fast shortens construction period。Product waste material is few, precision is high, pattern is many。Producing and be not subject to seasonal restrictions, winter also can produce, and solves winter construction problem。Assemble and have a certain amount of deformability between cylinder and wallboard, this addresses the problem the problem that body of wall produces crack due to temperature。But, this Assembled enclosing wall of this disclosure of the invention, its basis is still for the strip footing of cast-in-place concrete, and therefore, this Assembled enclosing wall falls within partial precast Assembled enclosing wall, neither fabricated enclosure wall prefabricated, complete entirely。
Prestressed concrete pipe pile is widely used in the foundation engineering of modern architecture, particularly with the building built on unstable soil layer or Soft Soil Layer and infrastructure projects, prestressed concrete pipe pile is by being transferred on the stable supporting course of underground by the load of building, thus supporting building, it is ensured that its safety and stablization。
Summary of the invention
