Description

  TECHNICAL FIELD The present application relates to the technical field of structural engineering, and more particularly to a novel prefabricated structural system and its assembly method. Specifically, the present application relates to a prefabricated structure system that employs a tenon-and-mortise-like configuration for connecting joints and can be used in steel frame structures, reinforced concrete structures, and wooden structures, and an assembly method thereof.

  The steel frame structure may include main structural members such as columns, main beams, sub-beams, and columns, which are connected as an integrated structure via connection joints.

  Currently, the most commonly used methods for connecting joints include high strength bolt joints and welding. Generally, in a steel frame processing factory, a steel frame member (such as a beam and a pillar) and a connecting plate are pre-processed, the connecting plate and the stiffening plate are welded, and a bolt hole is pre-drilled at a position where a bolt joint is required. The pre-machined members are then transported to the construction site, hoisted to the correct position and then joined using high strength bolt joints or welding.

The method for connecting joints described above may be accompanied by the following imperfections.
1) When the high-strength bolt joining method is used, each joint requires tens or hundreds of bolt holes on the member and the connecting plate, which may significantly increase the processing time and the processing cost.
2) Since component parts are not mass-produced at processing plants, errors occur on a daily basis. As a result, component interlocking can be difficult due to prefabricated composition errors due to different components and production processes.
3) When the steel frame members are transported to the construction site, hoisted in place, and then connected by bolts, manual fixing of the bolts is required. Fixing each bolt requires three work steps: temporary fixing of the bolt, initial screwing of the bolt and final screwing of the bolt, which can significantly increase the site workload and cost.
4) When connecting by on-site welding, it is generally necessary to perform a pre-heat treatment before welding, which not only increases the workload and cost of the site, but also the experience and skill of the welder, the welding procedure, and It is also easily affected by the welding environment such as weather conditions and welding position. Therefore, it is difficult to guarantee high quality in the field welding.

A tenon joint is formed between the second wedge-shaped recesses provided at the ends of the upper and lower flanges of the second C-shaped sleeve and the second wedge-shaped protrusions on both sides of the sub-beam fixing steel plate. Inserting the sub-beam fixing steel plate into the second C-shaped sleeve so that the sub-beam connecting end is constrained by
16. The method of claim 15, including. The main beam - the step of fixing the sub Ryoren sintered sleeve, the main beam - Fukuhari upper flange and the main beam of the main beam so as to secure the coupling sleeve - the intersection between the sides of Fukuhari coupling sleeve Welding the shear stud to an upper surface of the main beam so that the shear stud is positioned in
The method according to claim 16 or 17. In the step of inserting the main beam connecting end into the first C-shaped sleeve, the restraining protrusion provided on the bottom portion of the lower flange of the main beam connecting end is a bottom portion of the first C-shaped sleeve. Inserting the main beam connecting end of the main beam into the first C-shaped sleeve of the beam-column connecting sleeve laterally from a side of the main beam so that the main beam connecting end of the main beam fits within a restraining groove provided in the main beam. including,
The method according to claim 14. The step of connecting the first box-shaped steel pipe to the column connecting end is performed by engaging a protruding tooth provided on an inner surface of the first box-shaped steel pipe with a groove provided on an outer surface of the column connecting end. So that the first box-shaped steel pipe of the beam-column connecting sleeve is connected to the column connecting end of the column from the upper side of the column.
The method according to claim 14. The step of connecting the first box-shaped steel pipe on the column connection end of the column includes contacting an end surface of the column connection end with a surface of an internal horizontal stiffener in the first box-shaped steel pipe. Thus, connecting the first box-shaped steel pipe of the beam-column connecting sleeve onto the column connecting end of the column from above the column.
The method according to claim 14. Further comprising applying a steel adhesive between the connecting surfaces of at least one of the connecting ends.
The method according to claim 14. Further comprising pre-processing a reinforced concrete member to form the pillar and the main beam having a pillar connecting end and a main beam connecting end inserted into the beam-column connecting sleeve.
The method according to claim 14. The method further includes pre-processing a wooden member to form each of the pillar and the main beam having a pillar connecting end and a main beam connecting end inserted into the beam-column connecting sleeve.
The method according to claim 14.
