Embodiment Construction

[0023] The present invention will be further introduced below in conjunction with the accompanying drawings and specific embodiments.

[0024] Aiming at the problems of ordinary reinforced concrete slabs, such as lack of bearing capacity, structural durability, and self-heaviness of the structure, the invention provides post-tensioned prestressed truss-type reinforced UHPC-foam concrete composite floor slabs, aiming at improving the comprehensive performance of the floor slabs. Make full use of UHPC's high compressive strength, high toughness and other properties, combined with the characteristics of foam concrete such as low density, high strength, low thermal conductivity, and good water resistance, to reduce the weight of the structure and reduce the energy consumption of the building. Applying prestress in the slab will further give full play to the advantages of UHPC, improve the crack resistance of the floor slab, and contribute to the realization of green economy and sus...

Abstract

The invention discloses a post-tensioned prestressed truss type reinforcement UHPC-foam concrete composite floor plate. The composite floor plate comprises foam concrete embedded in UHPC. Steel bar trusses are arranged on the left side and the right side of the foam concrete. Tie bars between the steel bar trusses are arranged between the steel bar trusses; prestressed tendons are arranged in the steel bar trusses and are close to the lower parts of the steel bar trusses; the prestressed tendons penetrate through the interiors of the corrugated pipes; a grouting opening and a grout outlet are formed in the two ends of the corrugated pipe respectively; the grouting opening is used for filling grouting materials; the prestressed tendons are fixed through anchorage devices, and steel base plates are arranged between the anchorage devices and the concrete. The invention provides the post-tensioned prestressed truss type reinforcement UHPC-foam concrete combined floor plate by comprehensively utilizing the respective characteristics of UHPC, foam concrete, a steel bar truss and prestress.

Description

technical field [0001] The invention relates to a structure and material of a building component, in particular to a post-tensioned prestressed truss-type reinforced UHPC-foam concrete composite floor panel, which belongs to the technical field of building structures. Background technique [0002] With the rapid development of my country's construction industry, various high-rise super high-rise buildings have sprung up. Concrete structures are the most widely used in various building structures. People have higher and higher requirements on the bearing capacity and seismic performance of structures. Ordinary concrete floor slabs can no longer fully meet the needs of the construction market. Improving the strength and quality of structural members and reducing their self-weight has always been an important research topic in the field of civil engineering. [0003] Before the construction of traditional cast-in-place slabs, scaffolding and formwork need to be erected, whic...
