Prefabricated concrete dense rib truss reinforced steel bar thermal insulation box type component

Abstract

The invention relates to a prefabricated concrete dense rib truss reinforced steel bar thermal insulation box type component, and belongs to the field of construction engineering. The prefabricated concrete dense rib truss reinforced steel bar thermal insulation box type component includes four concrete plates which are enclosed into a box type structure; the inside structure of each concrete plate is dense rib strip-type concrete provided with a truss reinforced steel bar I and a truss reinforced steel bar II; the dense rib strip-type concrete, upper layer thin-walled plate concrete with a steel wire plain net and lower layer thin-walled plate concrete with a steel wire plain net form a honeycomb type structure similar as a bent frame; effective overlapping joint of the truss reinforced steel bar I and the truss reinforced steel bar II inside the dense rib strip-type concrete are conducted so as to enhance the integrity. Without affecting the resistance performance of a traditional concrete box component, the weight of the prefabricated concrete dense rib truss reinforced steel bar thermal insulation box type component is reduced by half or more; the prefabricated concrete dense rib truss reinforced steel bar thermal insulation box type component reduces fire hazards and the consumption of the concrete and the reinforced steel bars, the concrete box component has thermal insulation and energy-saving functions, and the scope of application of the concrete box component in the field of buildings is expanded, industrialized production is achieved, the production is convenient and rapid, and building construction time is greatly shortened.

Description

technical field [0001] The invention relates to a prefabricated concrete dense rib truss steel bar insulation box-shaped component, which belongs to the field of construction engineering. Background technique [0002] At present, the conventional prefabricated concrete box-shaped components in my country's construction industry have the disadvantages of heavy weight, difficult transportation and hoisting, and when using prefabricated concrete box-shaped components as temporary residences, there are disadvantages of poor energy-saving effect; and general in-band, The prefabricated concrete box-shaped components with external insulation or sandwich insulation also have the following problems: 1. The box-shaped components with thermal insulation materials on the outside have poor durability and are easy to fall off; 2. The box-shaped components with thermal insulation materials on the inside will It directly affects the headroom size of the box. 3. The box-shaped components with ...

[0002] At present, the conventional prefabricated concrete box-shaped components in my country's construction industry have the disadvantages of heavy weight, difficult transportation and hoisting, and when using prefabricated concrete box-shaped components as temporary residences, there are disadvantages of poor energy-saving effect; and general in-band, The prefabricated concrete box-shaped components with external insulation or sandwich insulation also have the following problems: 1. The box-shaped components with thermal insulation materials on the outside have poor durability and are easy to fall off; 2. The box-shaped components with thermal insulation materials on the inside will It directly affects the headroom size of the box. 3. The box-shaped components with sandwich insulation similar to the "sandwich" structure often have shortcomings such as thicker concrete walls, poor mechanical performance, and easy cracking.
