Anti-bending reinforcing structure for prefabricated hollow floors and construction method of anti-bending reinforcing structure

Abstract

The invention discloses an anti-bending reinforcing structure for prefabricated hollow floors and a construction method of the anti-bending reinforcing structure. The anti-bending reinforcing structure comprises core grouting reinforcing structures for prefabricated hollow floor holes and suspension reinforcing structures for prestressed steel wire ropes. The core grouting reinforcing structures for the prefabricated hollow floor holes comprise the hollow floor holes, grouting hole channels, through rebars and grouting materials. The suspension reinforcing structures for the prestressed steel wire ropes comprise anchorage device systems, reserved pipelines and the prestressed steel wire ropes, the reserved pipelines are arranged in the grouting materials in the first prefabricated hollow floors, the prestressed steel wire ropes are arranged at the bottoms of the second prefabricated hollow floors, and the two ends of the prestressed steel wire ropes penetrate through the reserved pipelines of the first prefabricated hollow floors on the two sides of the corresponding second prefabricated hollow floors and are anchored through the anchorage device systems. According to the structure, the problem of insufficient bearing capacity of the prefabricated hollow floors can be effectively solved, and the integrality, the bearing capacity and shock resistance between the prefabricated hollow floors are further improved.

Description

technical field [0001] The invention belongs to the field of building structures, and in particular relates to a bending-resisting reinforcement structure of a prefabricated hollow floor slab and a construction method thereof. Background technique [0002] According to statistics, about 50% of the buildings in our country have entered the middle-aged and old age, and about 2.5 billion square meters of buildings have the possibility of engineering quality problems or accidents in different situations, including various natural disasters on buildings. varying degrees of damage and destruction. Renovating, renovating and strengthening old buildings will gradually become the main task in the field of construction in our country. [0003] For masonry houses built before 1998, most of the floor structures are prefabricated hollow floor slabs. The integrity of the prefabricated floor in the brick masonry structure building is poor, and the bearing capacity of the prefabricated ho...
