Steel wire mesh bent reinforced Z-shaped section concrete column and making method

Abstract

The invention discloses a steel wire mesh bent reinforced Z-shaped section concrete column and a making method, and belongs to the technical field of shock absorption and disaster prevention. The section of the column is Z-shaped, and the column is positioned at the Z-shaped corner of a longitudinal and transverse wall; the ratio of the limb length to the limb thickness of the Z-shaped column is 2-4; and the column consists of concrete 1, steel wire meshes 2, concave key grooves 3 and a Z-shaped steel wire mesh skeleton 4. The making method comprises the following steps of: bending the steel wire meshes 2 into the Z-shaped steel wire mesh skeleton 4 according to the design size, supporting a template, pre-burying connecting steel bars 3 or reserving end grooves 4, pouring the concrete 1, and thus forming the steel wire mesh bent reinforced Z-shaped section concrete column. The transverse steel wire intervals of the steel wire mesh skeleton are dense, so the shearing resistance is good, and brittle shear fracture of a special-shaped short column can be prevented; the end grooves are reserved at the ends of the section of the column or the connecting steel bars are connected with a lightweight ecological wallboard, so that the aims of enhancing the integrity of a house and promoting the integral anti-seismic and energy dissipation capabilities are fulfilled; and the column is suitable for rural houses, and has a broad application prospect.

Description

technical field [0001] The invention relates to a Z-shaped cross-section concrete column with steel mesh bending and forming and its method, and belongs to a new type of concrete column with Z-shaped cross-section and bending steel mesh, which is practical, low in cost and suitable for residential buildings in villages and towns. and practice. Background technique [0002] As an unpredictable and extremely destructive natural disaster, earthquakes have brought huge losses to people's lives and property. In recent years, my country is in a period of frequent earthquakes. In 2006 alone, there were 17 earthquake disasters. Among them, the Wenchuan earthquake caused economic losses as high as 645.1 billion yuan, and more than 100,000 casualties. At the same time, my country's earthquake areas are widely distributed, and the areas with fortification intensity of 6 degrees and above account for more than 60% of the country's land area, and most of them are located in economically...
