Fabricated building structure combined pile foundation joint structure

Abstract

The invention discloses a fabricated building structure combined pile foundation joint structure. The fabricated building structure combined pile foundation joint structure comprises a pile foundation base, a movable supporting assembly, a motion monitoring assembly and a pile foundation fixing assembly fixedly installed on the bottom face of the pile foundation base. A pile foundation frame is fixedly installed on the top face of the pile foundation base, a building pile support connected with the top end of the movable supporting assembly is movably connected with the top face of the pile foundation frame, and a movement limiting assembly is fixedly installed on the top face of the pile foundation frame. The movable supporting assembly comprises a supporting seat and a movable supporting rod, and a supporting ball block is fixedly connected with the bottom end of the movable supporting rod. According to the fabricated building structure combined pile foundation joint structure, the movable supporting assembly structure is arranged, and the supporting seat and the movable supporting rod are used for movably connecting the building pile foundation, so that when the building shakes under the condition of external force or natural disasters, the vibration can be transmitted to a main steel frame from the ground, the main steel frame and a wallboard form an integral structure along with the vibration, structural damage caused by relative movement of the main steel frame and the wallboard is avoided, and the practicability of the fabricated building structure is improved.

Description

technical field [0001] The invention relates to the technical field of prefabricated buildings, in particular to a combined pile foundation node structure of a prefabricated building structure. Background technique [0002] Prefabricated building refers to the transfer of a large number of on-site operations in the traditional construction method to the factory, where the building components and accessories (such as floors, wall panels, stairs, balconies, etc.) are processed and manufactured in the factory, and then transported to the construction site. Finally, the building is assembled and installed on site through reliable connection methods. Prefabricated buildings mainly include prefabricated concrete structures, steel structures, modern wooden structures, etc. The customary steel frame building structure generally requires a main skeleton structure, including internal links, vertical columns, horizontal beams, roof trusses, etc., and secondary plate members, such as c...

AI Technical Summary

Problems solved by technology

The customary steel frame building structure generally requires a main skeleton structure, including internal links, vertical columns, horizontal beams, roof trusses, etc., and secondary plate members, such as connected to the main frame structure in various ways, so as to form Vertical walls, flat floors, ceilings, roof components, etc., the cap is used as the force transmission body between the pile foundation and the upper structure, and the main connection methods between it and the pile foundation are as follows: the top of the pile foundation is directly buried in the cap, the pile foundation The anchoring reinforcement is welded on the top end plate; but this connection method has defects: the connection method of the pile foundation top directly buried in the cap is easy to construct

[0003] Existing pile caps mainly use rigid connections. In the improvement of the safety of prefabricated buildings, more and more prefabricated buildings adopt lightweight layout to reduce the load-bearing pressure of the supporting structure of the house. After lightweight assembly In the case of external shaking, when the building is shaken by external force, the vibration is transmitted from the ground to the main steel frame, and the main steel frame vibrates accordingly, while the vibration amplitude of the wall panel is usually smaller than the vibration amplitude of the steel frame, so this also leads to the easy connection between the main steel frame and the wall panel. Cracks occur, and the occurrence of cracks seriously reduces the safety of prefabricated buildings. Simply set up shock-absorbing structures such as rubber pads. When the structure of the building is subjected to vibration and shock, the existing shock-absorbing structures have poor shock-absorbing and buffering performance. , the protective effect on the building structure is also poor, and it is easy to produce long-term bad vibrations that cause structural wear and tear, resulting in a low practical life of the building.

In view of this, the existing problems are studied and improved, and a prefabricated building structure combined pile foundation node structure is provided to solve the current problem of no shock-absorbing structure and bad vibration damage to the safety of the structure. technology to achieve the purpose of solving problems and improving practical value
