Truss unit, truss system and method for enhancing bearing capacity and integrity of building prefabricated slab

Abstract

The invention discloses a truss unit, a truss system and a method for enhancing bearing capacity and integrity of a building prefabricated slab. The truss unit comprises a plurality of steel web member assemblies which are fixedly installed with one another and are fixedly installed with the building prefabricated slab at the same time, and a bamboo lower chord which is fixedly installed with thesteel web member assemblies; the bamboo lower chord is located below the steel web member assemblies, and the two ends of the bamboo lower chord are fixedly installed on the building prefabricated slab at the same time. According to the truss unit, the truss system and the method for enhancing the bearing capacity and the integrity of the building prefabricated slab, the truss unit is flexible insection form, the bearing capacity is high; the deformation performance, the ductility, and the anti-seismic property are good; all the components work cooperatively to make up for respective defects,and the integrity is good; the industrialization degree is high, the construction quality and progress are guaranteed, and various kinds of pollution caused in the construction process are reduced; materials are saved, and the economy is good; recycling rate is high.

Description

technical field [0001] The invention belongs to the field of building construction, and in particular relates to a truss unit, a system and a method for enhancing the bearing capacity and integrity of prefabricated panels of buildings. Background technique [0002] In real life, due to the change of the use function of the room, the load of the prefabricated slab of the building increases, so that the bearing capacity, integrity and deformation of the original prefabricated slab of the building cannot meet the requirements. The existing reinforcement methods include: pasting carbon fiber plate / cloth reinforcement method, pasting steel plate reinforcement method, enlarging section method, adding force beam and other methods, but these methods all have certain limitations. [0003] Therefore, in view of the above technical problems, it is necessary to provide a truss unit, a system and a method for enhancing the bearing capacity and integrity of the prefabricated panels of bui...
