Novel beam column connection joint and construction method thereof

Abstract

The invention discloses a novel beam column connection joint and a construction method thereof. The novel beam column connection joint comprises a prefabricated column, a prefabricated beam and a beam end cast-in-situ area. A column body steel jacket box for prefabricating a column body is pre-arranged on the prefabricated column, and a U-shaped beam supporting plate with an opening facing upwards is arranged on a lateral plate of the column body steel jacket box. An upper longitudinal rib and a lower longitudinal rib of the prefabricated beam are both connected with the lateral plate of the column body steel jacket box through connecting plates. A waist rib of the prefabricated beam is connected with the U-shaped beam supporting plate. The beam end cast-in-situ area is formed by pouring concrete on-site on the U-shaped beam supporting plate, and the novel beam column connection joint is formed by connecting the prefabricated column and the prefabricated beam. The construction method comprises the steps of manufacturing the column body steel jacket box, manufacturing the prefabricated column, welding the U-shaped beam supporting plate, mounting the prefabricated beam, forming the novel beam column connection joint, and the like. According to the novel beam column connection joint and the construction method thereof, the problem that steel bars in a beam column joint area collide one another can be thoroughly avoided, cast-in-situ and formwork supporting in a joint area are avoided, and support installation at the beam end is avoided.

Description

technical field [0001] The invention belongs to the technical field of concrete frame structures of prefabricated construction projects, and in particular relates to a novel beam-column connection node for connecting beams and columns by using a steel box, a connecting plate and a U-shaped beam supporting plate and a construction method thereof. Background technique [0002] The existing prefabricated beam and column joints are mainly prefabricated beams and columns and cast in-situ in the joint area. The beam and column reinforcements of such joints meet in the joint area, which often causes collisions between beams and column reinforcements, and in order to It is convenient to arrange steel bars, but the cross-section of beams and columns is usually artificially increased, which will increase the construction cost to a certain extent, and the quality of cast-in-place in the node area is difficult to control. In addition, there is also a process in which beams and columns a...
