Description
Technical Field
The utility model belongs to the technical field of building walling, concretely relates toFull prefabricated wall。
Background
As is known, most of the traditional building enclosures are solid enclosures, hollow enclosures, etc. The solid enclosing wall comprises dry masonry, mortar masonry, concrete blocks and the like. The hollow enclosing wall is formed by combining brickwork and a fence. The construction method is mostly a site masonry method and comprises the steps of site positioning and paying off, foundation earthwork excavation, foundation cushion concrete pouring, foundation template installation, foundation reinforcement binding, foundation concrete pouring, column or wall building (or pouring), fence installation, outer wall coating, inspection and acceptance inspection and the like. The method has the defects of large temporary land occupation, multiple construction procedures, long engineering period, poor apparent quality, more generated wastes and large environmental pollution, and the wall foundation on a bad foundation is easy to generate uneven settlement, thereby causing wall cracks and even toppling, and having poor seismic resistance.
BEIJING HONGTANG CREATION TECHNOLOGY Co.,Ltd.The AS modular construction system was brought into China in cooperation with the university of the Japanese early rice field and the Japan Yeze corporation. For many years, the company has built up the river-north China Rongtang, Guangxi jade and the like in the Jiangsu Ling Kou, Shanxi Datong, Fujian Xiyun, Hebei Xingtang and Guangxi jadePartially prefabricated wall. The partially prefabricated enclosure wall is characterized in that,the foundation and the upright post of the whole enclosing wall are formed by casting the on-site vertical template,only the wall panels and the pressure top pieces and the column caps are prefabricated.
Beijing taikeli Hi Tech Co.,Ltd.Developed and producedCement-based assembled enclosureThe wall-mounted type building block is composed of a foundation (cup-shaped and strip-shaped), upright posts (H-shaped and U-shaped), wall boards (with width modulus of 600mm, 500mm and 300 mm), a post cap and a wall capping. The wall board is made by adopting light high-strength cement-based extrusion molding produced by introducing Germany, the product thoroughly overcomes the defects of low strength, poor regularity and the like of the foamed concrete ALC board, and has the remarkable characteristics of good appearance effect of the wall body, long service life (30-50 years), low maintenance cost (basically no maintenance), short construction period (saving 50 percent of the construction period compared with the traditional masonry wall), strong earthquake resistance and the like. The cement-based assembled enclosure wall is applied to projects such as Wulan Hada-Kudzuvine temple 66KV transformer substations, Changchun ginseng flower 66KV transformer substations, Zhang Jiakou Xishan park 110KV transformer substations and the like. However, it is possible to use a single-layer,the construction of the cement-based assembled enclosure still needs to excavate earthworkThe cup-shaped or strip-shaped base preform can be embedded.
24.4.2013, the patent office of the national intellectual property office discloses the Guo Ming of Shenyang megaantoan modern architecture industry park, the fabricated enclosure applied for Liqingshan (application number CN 201310037917.4). The invention discloses an assembled enclosure wall which mainly comprises components of a column body and a wallboard, wherein the column body and the wallboard components are assembled on site to form the enclosure wall. The components are molded in a factory and then transported to a construction site for assembly, so that the construction is convenient and fast, and is not limited by seasons. The assembled enclosure wall of the invention adopts different combination modes to form various fancy enclosure walls. The components are produced in a factory and then transported to a construction site for assembly, the assembly on the site is simple and rapid, and the construction period is shortened. The product has less waste, high precision and many styles. The production is not limited by seasons, and the production can be carried out in winter, so that the construction problem in winter is solved. A certain amount of deformability exists between the assembled columns and the wall boards, so that the problem that cracks are generated on the wall body due to temperature is solved. However, the assembled enclosure disclosed in the invention,the foundation is still a bar foundation of cast-in-place concreteThus, the assembled enclosureAlso belongs to a partially prefabricated wall, not a fully prefabricated and fully assembled wall。
The prestressed concrete pipe pile is widely applied to foundation engineering of modern buildings, particularly buildings and infrastructure projects built on unstable soil layers or soft soil layers, and the prestressed concrete pipe pile transmits the load of the buildings to an underground stable bearing layer, so that the buildings are supported, and the safety and stability of the buildings are ensured.
