Unbonded prefabricated assembly type frame building foundation joint and connecting method thereof

Abstract

The invention relates to an unbonded prefabricated assembly type frame building foundation joint and a connecting method thereof. The unbonded prefabricated assembly type frame building foundation joint comprises a prefabricated bearing column, a prefabricated ground beam, an underground pile, an anchorage device, an inhaul cable and a prefabricated ground beam tray, wherein the prefabricated bearing column is of a solid columnar structure, a plurality of column holes penetrating through the axial direction of the prefabricated bearing column are formed in the prefabricated bearing column, a through hole penetrating through the axial direction of the prefabricated ground beam is formed in the prefabricated ground beam, the through hole is configured to allow the lower end of the prefabricated bearing column to be inserted therein, the underground pile is of a hollow columnar structure, the anchorage device is of a solid columnar structure, a plurality of anchorage device holes penetrating through the axial direction of the anchorage device are formed in the anchorage device, the anchorage device is detachably installed in a cavity of the underground pile, the inhaul cable is arranged in the column holes of the prefabricated force bearing column and the anchorage device holes of the anchorage device in a penetrating mode, and the prefabricated ground beam tray is of a hollow columnar structure and is arranged at the upper end of the ground pile in a sleeving manner. According to the unbonded prefabricated assembly type frame building foundation joint, the prefabricated assembly type is really achieved, the construction period is greatly shortened, the bearing capacity is high, the overall performance is good, and the joint can be repeatedly used, is green and environmentally friendly and has quite high economic benefits.

Description

technical field [0001] The invention relates to a non-adhesive prefabricated frame building foundation node and a connection method thereof, belonging to the field of design and construction of prefabricated buildings. Background technique [0002] With the development of the industrialization of building structures, prefabricated buildings are widely used at home and abroad because of their simple construction, short construction period, low environmental pollution, and labor saving, and they are also the development trend of building structures. Whether the design of prefabricated frame structure columns and threaded pile joints is reasonable or not not only affects the performance of the structure, but also affects the convenience of construction. According to the previous construction situation, the connection between the pile foundation and the beam-slab-column is mainly carried out on-site connection through cast-in-situ piles or piles reserved for reinforcement, and t...

Whether the design of prefabricated frame structure columns and threaded pile joints is reasonable or not will not only affect the performance of the structure, but also affect the convenience of construction

According to the previous construction situation, the connection between the pile foundation and the beam-slab-column is mainly carried out on-site connection through cast-in-situ piles or piles reserved for reinforcement, and then pouring. Disadvantages such as densely packed, not densely vibrated concrete, relatively cumbersome construction, etc., and does not have the function of secondary disassembly and assembly
