Embodiment Construction
[0022] A novel assembled structural prefabricated column member according to the present invention comprises a prefabricated column (1), a support bracket (2), and a pre-embedded nut (3). The support bracket (2) is mainly composed of high-strength bolts (4), reinforcing steel plates (5), positioning steel plates (6), angle steels (7), and nuts (8). When producing the prefabricated column (1), the nuts (3) are pre-embedded according to the structural construction drawing in advance to fix the support bracket (2). According to the structural construction drawings, select a reasonable support bracket (2) according to the size of the composite beam (9), and use high-strength bolts (4) to connect the support bracket (2) with the prefabricated column (1). (2) Width D=dimension of composite beam (9)+50mm, the purpose is to facilitate the installation of composite beam (9), the construction is convenient and reliable, and the difficulty of construction is effectively reduced.

The invention discloses a novel prefabricated structure precast column unit which comprises an embedded nut arranged in a precast column. The distance between the embedded nut and the top of the precast column is 120mm, the spacing of two sides of a center line of a beam is D / 4 (D refers to the width of a supporting bracket), the supporting bracket mainly comprises angle steel, a positioning steelplate, a reinforcing steel plate, a high-strength bolt and a nut, during industrial production, circular holes are formed in the side face of the angle steel, the depth of each circular hole is 5mm,the diameter of each circular hole is 100mm, the positioning steel plate is arranged at the top of the angle steel, the reinforcing steel plate is arranged on the side face of the angle steel, and a composite beam is fixed. The novel prefabricated structure precast column unit has the advantages that erection of a vertical support at the end of the junction of the precast column and the compositebeam is omitted, on-site construction is simple and convenient, a site is less in loading, the precast column, the composite beam and the supporting bracket can be produced in a standardized manner ina factory, economic feasibility is strong, the supporting bracket can be recycled, a green building conforms to national advocacy, the supporting bracket is arranged at the junction of the precast column and the composite beam, mortar leakage in casting can be avoided, and construction quality is ensured.
Description
technical field [0001] The invention relates to a building component, in particular to a construction method for a new prefabricated column component and a beam-column joint of a prefabricated structure. Background technique [0002] According to the requirements of the current prefabricated monolithic building code, in order to ensure the progress of the project and ensure the quality of the project, the connection method of the prefabricated structural components and nodes in the prefabricated monolithic building is very important. Among the joint connections of prefabricated frame structures, the connection between prefabricated columns and composite beams is the most complex, with the highest technical content and the most difficult construction. In the existing construction methods of precast columns and composite beams, in order to realize the joint connection between precast columns and composite beams and ensure the positioning and stability of composite beams, suppo...
