Abstract

The invention discloses a connection device and a connection method for preventing a steel structure column foot from being tensioned. The connection device comprises a prestressing pull bar pair, a combined node plate and an embedded casing. The prestressing pull bar pair formed by integrally connecting an upper section of a steel pull bar with a lower section of the steel pull bar through a forward and reverse buckle casing, and two ends of the steel pull bar are provided with threads; the lower section of the steel pull bar of the prestressing pull bar pair penetrates the embedded casing embedded in a tension side of a concrete foundation in advance to be connected with a nut; the upper section of the steel pull bar of the prestressing pull bar pair penetrates a hole formed in the combined node plate welded to the tension side of a steel column in advance to be connected with the nut; the upper and lower sections of the steel pull bar exert prestress upon the steel pull bar through the forward and reverse buckle casing. Therefore, the steel column foot can be prevented from being tensioned, using amount of sill anchors can be reduced, and connection rigidity of the steel column foot can be improved.

Description

Technical field

[0001] The invention belongs to the technical field of building structures, and more specifically, relates to a device and method for tension-free connection of steel structure column feet. Background technique

[0002] As environmental protection and sustainable development have increasingly become a veto indicator in all walks of life, steel structures have been promoted as key technologies by the Ministry of Construction for their advantages in recyclability and pollution-free manufacturing and installation. From a global perspective, steel structures have become the development trend of various types of buildings.

[0003] The important advantage of the steel structure is that it is quick to manufacture and install. The connection between the steel column and the foundation, like the superstructure, adopts the "bolt" installation method, which is conducive to speed. At present, the typical installation structure of steel structure column foot is as figure 1 , ...
