Abstract
The invention discloses a double-layer hoop-confined high-strength concrete composite column comprising a high-strength concrete inner core. The high-strength concrete inner core is peripherally covered with a concrete outer layer, an inner hoop and an outer hoop are arranged in the concrete outer layer, the inner hoop wraps the concrete inner core, the outer hoop is located at the position, close to the surface, of the concrete outer layer, and the inner hoop and the outer hoop are strained with transverse bars. The invention further discloses a manufacture method of the double-layer hoop-confined high-strength concrete composite column. The double-layer hoop-confined high-strength concrete composite column takes the high-strength concrete inner core as a skeleton, the inner hoop and the outer hoop are set up depending on the high-strength concrete inner core and strained with the transverse bars to enable firmness to be good after the concrete outer layer poured on the concrete inner core is combined with the high-strength concrete inner core, and bending resistance, shearing resistance and tensile strength of the double-layer hoop-confined high-strength concrete composite column are improved highly and beneficially.
Description
Technical field
The present invention relates to a kind of double-deck stirrup restraint and high-strength concrete combined column.Present invention also offers manufacture above-mentionedThe method of double-deck stirrup restraint and high-strength concrete combined column。
Background technology
Tradition cylinder is generally adopted common reinforced concrete pile, the bearing capacity of pillar is relatively low, ductility is poor, fragility is big, when there is violent earthquake, owing to the restraining forces of stirrup causes that bridge and high building structure post produce to destroy not, building or Collapse of Structures, shock resistance is not enough.In order to improve above-mentioned deficiency, the present invention adopts the double-deck concrete method of stirrup restraint and high-strength, improves the properties of cylinder, provides technical support for elevated bridge and skyscraper cylinder.
Summary of the invention
In view of the deficiency that background technology exists, the technical problem to be solved is to provide a kind of bending resistance, resistance to compression, anti-seismic performance better double-deck stirrup restraint and high-strength concrete combined column.
The present invention has adopted the following technical scheme that: double-deck stirrup restraint and high-strength concrete combined column, it is characterized in that: include high-strength concrete inner core, high-strength concrete inner core periphery is enclosed with concrete outer layer, with internal layer stirrup and outer layer stirrup in concrete outer layer, described internal layer stirrup is wrapped on concrete inner core, described outer layer stirrup is in the close appearance place of concrete outer layer, described internal layer stirrup and outer layer stirrup and adopts transverse steel tension.
The method of the above-mentioned double-deck stirrup restraint and high-strength concrete combined column of manufacture provided by the invention, comprises the following steps: A, makes mould or sets up pouring template high-strength concrete inner core, after the solidification of high-strength concrete inner core mummification, removes mould or template；B, set up internal layer stirrup and outer layer stirrup successively around high-strength concrete inner core, between internal layer stirrup and outer layer stirrup, adopt transverse steel tension；C, set up template or mould around outer layer stirrup, and surround cast concrete outer layer in the inner chamber formed to template or mould and high-strength concrete inner core；D, until concrete outer layer solidify after form removal.
Double-deck stirrup restraint and high-strength concrete combined column provided by the invention is with high-strength concrete inner core for skeleton, high-strength concrete inner core is relied on to set up internal layer stirrup and outer layer stirrup, and after straining with transverse steel, firmness after making cast concrete thereon outer layer be combined with high-strength concrete inner core is fabulous, is conducive to improving double-deck stirrup restraint and high-strength concrete combined column bending resistance, shearing resistance and tensile strength and is greatly improved.
Accompanying drawing explanation
The present invention has drawings described below:
