Novel steel-concrete beam-column joint construction structure and comprehensive construction method

Abstract

The invention provides a novel steel-concrete beam-column joint construction structure and a comprehensive construction method. A joint three-dimensional model is established by utilizing a BIM technology before main body structure construction, connecting joints of concrete beams and steel reinforced columns are deepened, rebar putting plate integrated processing is conducted by utilizing BIM data, the BIM technology is utilized to simulate joint construction before on-site construction, and an optimal scheme is determined; the steel reinforced columns are transported to a construction site for being installed, column longitudinal bars are fixed to the outer sides of the steel reinforced columns through rebar putting plates in the vertical direction, and beam longitudinal bars and torsional bars are fixed in the transverse direction; and concrete pouring is conducted. Joint deepening, three-dimensional expressing, construction simulating are conducted by utilizing the BIM technology, so that conciseness and efficiency are achieved. The rebar putting plates are precisely welded to the steel reinforced columns in advance, on-site construction is extremely convenient, and the construction period is shortened. The invention belongs to the technical field of building construction.

Description

technical field [0001] The invention relates to a novel comprehensive construction method for steel-concrete beam-column joints, belonging to the technical field of new auxiliary construction for building construction. Background technique [0002] There are five main ways to connect traditional steel columns and concrete beams: ① Direct steel bar penetration method. The disadvantage of this method is that when the longitudinal reinforcement is within the width of the steel frame flange, the perforation on the flange will weaken the steel frame flange. The disadvantage of this method is that it will increase the amount of materials (formwork, steel bars, concrete) and construction work, and sometimes affect the appearance of the building; ③The steel bar connector method, the method The disadvantage of the method is that the connector is pre-welded on the steel frame according to the number of steel bars, and there are constraints in the horizontal and vertical directions.

[0002] There are five main ways to connect traditional steel columns and concrete beams: ① Direct penetration of steel bars. The disadvantage of this method is that when the longitudinal reinforcement is within the width of the steel frame flange, the perforation on the flange will weaken the steel frame. The disadvantage of this method is that it will increase the amount of materials (formwork, steel bars, concrete) and construction work, and sometimes affect the appearance of the building; ③The steel bar connector method, the method The disadvantage of the method is that the connector is pre-welded on the steel frame according to the number of steel bars, and there are constraints in the horizontal and vertical directions. This requires high positioning accuracy of the connector on the steel frame and the positioning of the steel bars, and it is generally difficult to achieve accurate positioning;④ The concrete beam is converted to the steel frame beam method. The disadvantage of this method is that the amount of steel is greatly increased. More, the construction is more cumbersome, and the amount of steel will increase

Traditional methods usually use two-dimensional graphs for node deepening. For slightly complex nodes, the deepening effect is not good, and two-dimensional drawings also have the disadvantage of large information transmission loss.
