Problems solved by technology

However, according to the above method, the internal force generated by the foundation pile under the load of the superstructure is very uncontrollable, and the distribution is also very uneven. The position where the internal force is relatively concentrated may need to increase the section of the position, while the position where the internal force is small, It fails to exert its mechanical performance, based on this, it causes material waste to the foundation pile, and the economy is not good

Embodiment 1

[0061] see figure 1 , the invention provides a method for loading and node connection of foundation piles, comprising

[0062] 101. Connect the superstructure to the foundation pile in a first connection manner, so that the superstructure is in a movable state relative to the foundation pile, and apply a first load on the superstructure.

[0063] In this embodiment, the foundation pile 20 refers to a foundation or a pile foundation, etc., which is subjected to axial force, shear force, bending moment and the like. The superstructure 10 can be a structure such as a beam, column or plate connected with foundation piles.

[0064] Further, for the convenience of actual construction, the first connection method may be a bolt connection or a plug-in setting material (such as concrete) pouring connection.

[0065] Please also refer to figure 2 , the first optional implementation manner, the first connection method is bolt connection, then in the above step 101, the following step...

Abstract

The invention discloses a method for loading and node connection of foundation piles, which includes: connecting a superstructure to the foundation piles in a first connection manner, so that the superstructure is in a movable state relative to the foundation piles; applying a first load to the structure; calculating the first internal force of the foundation pile in the movable state based on the first load; adjusting the superstructure relative to the foundation pile from the movable state to fixed State, apply a second load on the superstructure; based on the second load, calculate the second internal force of the foundation pile in the fixed state, superimpose the first internal force and the second internal force, to obtain The target internal force of the foundation pile, wherein the sum of the first load and the second load is equal to all loads received by the superstructure when it is fixed relative to the foundation pile. By adopting the method of the invention, not only the internal force of the foundation pile subjected to the upper load can be effectively homogenized, but also the construction method is simple and quick.

Description

technical field [0001] The invention relates to the technical field of structural engineering, in particular to a method for loading foundation piles and connecting nodes. Background technique [0002] The foundation or pile foundation of the engineering structure is collectively referred to as the foundation pile, and the foundation pile bears the load from the upper structure, usually axial force, shear force, bending moment, etc. [0003] At present, in the engineering design, the feasibility analysis of the structural design of the foundation pile is mainly to calculate the internal force of the foundation pile on the basis of fixing the foundation pile with the superstructure, and then bearing the load of the superstructure. However, according to the above method, the internal force generated by the foundation pile under the load of the superstructure is very uncontrollable, and the distribution is also very uneven. The position where the internal force is relatively co...
