Poking-groove liner tube node structure applied to on-site splicing of box-type support

Abstract

The invention relates to the technical field of construction engineering and especially relates to a poking-groove liner tube node structure applied to on-site splicing of a box-type support. The structure comprises lower-section supports (1) and upper-section supports (3), wherein cross sections of the lower-section supports (1) and the upper-section supports (3) are box-type cross sections; thetop of each lower-section support (1) and the bottom of each upper-section support (3) are welded in a face-to-face manner, and a weld joint (7) is formed; an adjustable poking-groove liner tube nodepart is symmetrically disposed in the inner chamber of each upper-section support (3); each adjustable poking-groove liner tube node part can adjust a construction seam through expansion and contracting and can provide cushion plate supporting for welding; and a separation plate (2) is welded inside the chamber body of each lower-section support (1) to form a sealed box shape. The structure is exquisite: each liner tube is driven by a poking rod to slide easily and stretch or contract freely, and each poking rod is clamped in a groove hole, so the liner tubes do not get stripped; and manufacture is easy: the liner tubes can be processed and manufactured in a standardized and batched manner.

Description

Technical field [0001] The invention relates to the technical field of construction engineering, and relates to a slotted liner node structure used for field splicing of box-shaped support, which can be widely used in the field spliced ​​node structure of box-shaped support members of various steel structure buildings, especially Slotted liner node structure for box-type support field splicing. Background technique [0002] The steel structure has good seismic performance, industrialized factory processing, and on-site assembly construction. It is an advantageous prefabricated building structure system. It meets the current national policy requirements for the promotion of prefabricated buildings and has broad development prospects. [0003] The steel frame support system is a structural system with excellent performance for applications and multi-high-rise buildings. As a lateral force resistant structure, the support has the advantages of high lateral resistance efficiency, econo...

Problems solved by technology

[0008] Welding at the gap, it is difficult to ensure that the weld is completely penetrated and has no defects, and meets the requirements of the first-class weld; if the liner is pre-set, there is no installation gap, and the support is difficult to fill in. This is a contradiction that exists at present.
