However, in existing norms, the mechanical properties of the two are equivalent, therefore, it is essential to further study the mechanical properties of hollow brick masonry and new expansion bolts.

Improved construction method of expansion bolt and annectent reinforcing bar in shell frame filled-wall;

Stress field analysis of hollow brick anchored by new expansion bolt

Based upon comparison of working principles of traditional expansion bolt and flat head inner expansion bolt the installation process of GRC is discussed.

Experiment on pullout and shearing resistances of expansion bolts in CS panel;

a technology how to ensure the fitting quality of the expansion bolts was introduced to improve the fitting quality of stone curtain wall when expansion bolts are used to connect the curtain wall and the major structure.

This paper compares the pipe-expansion screw with old-type mild steel expansion bolt in the their functions and application scope, and introduces the properties and application prospect of the new proprietary product.

Based upon neural networks, a nonlinear mathematical model of the protraction for the thermal expansion die bolt is developed.
