H-shaped steel sheet pile with bidirectional locking openings for combined steel sheet pile

Abstract

The invention provides an H-shaped steel sheet pile with bidirectional locking openings for a combined steel sheet pile, and belongs to the technical field of sheet pile walls, piles or other structural components for steel foundation engineering. The H-shaped steel sheet pile comprises a web and a wing plate mounted at the end of the web, and is characterized in that inner hooks or outer hooks are arranged at two ends of the wing plate, and the tail end of the wing plate is bent upwards and downwards to form a hook-shaped structure. The H-shaped steel sheet pile is applied to machining of sheet pile walls and the like, and has the advantages of high rigidity, flexible combination modes and the like.

Description

technical field [0001] The application relates to an H-shaped steel sheet pile for a combined steel sheet pile with two-way locks, which belongs to the technical field of sheet pile walls, piles or other structural components for steel foundation engineering. Background technique [0002] As an environmentally friendly material, steel sheet piles have many advantages such as prefabrication, light weight, high performance, simple construction, and recyclability. The application prospect in foundation pit support is bright. Composite steel sheet piles are usually composed of H-shaped steel and Larsen steel sheet piles. Locks are the key components. H-shaped steel and Larsen steel sheet piles are connected through locks. The structure of the locks directly affects the steel sheet pile. Combination mode and performance (including force performance, deformation performance and anti-seepage performance). At present, the common lock types include Larsen lock and CT lock, which can...

Problems solved by technology

Composite steel sheet piles are usually composed of H-shaped steel and Larsen steel sheet piles. Locks are the key components. H-shaped steel and Larsen steel sheet piles are connected through locks. The structure of the locks directly affects the steel sheet pile. Combination mode and performance (including force performance, deformation performance and anti-seepage performance). At present, the common lock types include Larsen lock and CT lock, which can be combined to obtain HUC, H+Hat and other combined steel plates, etc. , but the composition of the combined steel sheet pile is relatively simple, which can meet the simple structural wall assembly, but it cannot adapt to the slightly more complicated structural wall
