Support tie bar for cushion-type protection structure

Abstract

The invention discloses a self-supporting support tie bar for reinforcing a cushion structure made of a metal net. The cushion structure is used for civil engineering protection engineering. The support tie bar comprises a body structure (12, 112, 142) having a lower portion (22, 122, 162) for connection with a base mesh (T) of the cushion structure and an upper portion (18, 118, 148) for connection with a cover mesh of the cushion structure. The lower portion and the upper portion are connected to each other by one or more support tie bar branches that lie on a main plane of the body structure. At least one support member is connected to the main body structure and extends beyond the main plane so as to create an integral three-dimensional support tie bar structure that can stand independently. The support tie bars can be compactly folded, for storage and transportation, and opened in the position of the cushion structure. The invention further discloses a cushion structure made of a metal wire net for civil engineering protection work and a method for installing the cushion structure.

Description

technical field [0001] The present invention relates to the field of civil engineering for the protection of cliffs, slopes, banks, coasts and other such formations of natural or artificial origin. [0002] The invention has been especially developed for mat-type protective structures made of metal wire mesh, such as but not limited to double twisted metal wire mesh. The invention relates in particular to the special support ties used to reinforce this type of mat-type protective structure. Background technique [0003] A mat-type protective structure made of wire mesh (hereinafter referred to simply as a "mat") generally comprises a bottom sheet of wire mesh placed on the ground, from which extends vertically a membrane that defines the mat. The thickness, therefore, divides the mat into a series of compartments. These compartments are filled with a filler material, such as stone, which acts as a weight and filter, before being covered by a top wire mesh sheet which acts ...

AI Technical Summary

Problems solved by technology

[0006] Although the supporting ties of the known art perform the task of avoiding the expansion and deformation of the mat, their installation requires a lot of manual work, also to avoid them being flooded with stones when filling the mat compartment and thus before it is covered by the upper mesh Curved towards the bottom of the mat, thus making it difficult (when not impossible) to attach the lower mesh and upper mesh of the mat together

On the other hand, inserting support ties when filling is complete is a complex operation, often leading to low quality results (when not resulting in not being able to make at all)
