Bamboo-steel fiber reinforced concrete composite beam

Abstract

The invention discloses a bamboo-steel fiber reinforced concrete composite beam, comprising a bamboo beam, a perforated metal plate, adhesive glue and a cast-in-place steel fiber reinforced concrete layer. The bamboo beam is provided with a reserved seam in the length direction and provided with grooves at intervals; the bamboo beam and the cast-in-place steel fiber reinforced concrete layer are connected through the perforated metal plate; the lower part of the perforated metal plate is embedded into the reserved seam; the upper part and the lower part of the perforated metal plate are respectively provided with a circular upper hole and a circular lower hole; the reserved seam and the lower hole of the bamboo beam are filled with the bonding glue; the cast-in-place steel fiber reinforcedconcrete layer and the bonding glue respectively form an upper pin bolt and a lower pin bolt in the upper hole and the lower hole of the perforated metal plate; and the cast-in-place steel fiber reinforced concrete layer forms shear tenons at the positions of the grooves. Compared with a common bamboo structure, the bending rigidity of the section of the bamboo structure is greatly improved, theadverse situation of rigidity control design of the bamboo structure is thoroughly changed, and the bamboo-steel fiber reinforced concrete composite beam has the advantages of being high in bearing capacity and large in rigidity.

Description

technical field [0001] The invention relates to a composite structure, in particular to a bamboo-steel fiber concrete composite beam. Background technique [0002] Green, ecological, environmental protection, low-carbon new materials and innovative structural systems are the inevitable direction of the development of civil engineering science and technology. Bamboo is one of the important varieties of energy-saving and environmentally friendly biomass green materials. Studies have shown that bamboo structures are green, ecological, environmentally friendly, and low-carbon. Development has significant significance for forming a new structural system and reducing energy consumption of the structure. [0003] In addition to its superior performance, bamboo structures can also make full use of bamboo resources. Bamboo or bamboo structures have the following advantages: (1) Bamboo resources are easy to reproduce, save energy, and produce less pollution; (2) The structure is ligh...
