FR2500864A1 - Steel bracing for connecting and reinforcing metal gabions - has three dimensional frame for steadying gabion walls during filling - Google Patents

Abstract

The bracing has four articulating rods (A,B,C,D) with loops (2) for connecting to each other and hooks (1,3) for connecting together and to the metal mesh forming the gabion walls and base. The stirrup (A) is fixed to the gabion base with hooks (1), a vertical rod (B) is fixed to the stirrup (A) with a hook (3), and a horizontal bar (C) and end rod (D) fit into the top hook of the vertical rod. When the elements are assembled and lifted up, they are fixed to three gabion walls using the end hooks and form both longitudinal and transverse bracing.

Description

 the present invention relates to a metallic connection and reinforcement frame incorporated in the metal gabion.

The metallic gabion is used in certain work of
Civil engineering: road, support, watercourse, embankments etc.

 It is shaped in a special sheet of metallic canvas.

Prepared in the factory, it is folded to obtain, during its implementation on site, a box of parrallelipedic shape filled with stones containing a content of several cubic mtreks.

 Conceived to marry in mass work the movements of ground its filling must be carried out according to a particular technique.

 This includes the construction on the inner perimeter and on the height of the box of a dry stone wall.

This low wall taking the place of articulation with the gabion stores a heap of stones filling it up to the height of the cover which is folded down and sewn with wire.

 According to a known method for reinforcing the gabion and correcting the deformations of the metal canvas box due to the loading of the materials, wire rods are used.

 The installation of these tie rods consists in connecting the opposite sides of the gabion through the materials filling it.

 This process does not include any preparatory provision for the implementation of the gabion.

 Another known method consists in partitioning the gabion by the addition of metallic canvas panels. This more expensive process has the disadvantage of compartmentalizing the materials by causing them to be split, which can lead to a cause of rupture of the chain of the dry stone wall.

 According to the invention, the reinforcement incorporates a connection and reinforcement is a device intended to improve, in addition to the ease of use of the gabion, its properties of flexibility and cohesion.

 Avoid any continuity of the dry stone wall that may result from improperly placed tie rods and even more the partitioning of the gabion.

 To ensure its balance during the implementation and to consolidate it by a close connection with the reinforcement whose device is anchored within the mass of materials it contains.

 The frame is constituted by a steel wire device according to the drawing annex I: .ig 2.

This device includes wI elements: the stirrup A the vertical rod B the horizontal bar C the end rod D
I. ' bracket 2 has a hook 1 at its lower ends connection loop 2 at the top.

 The vertical rod B is provided with a hook 3 at its ends and a tie loop 2 along its length.

 The horizontal bar C is provided with a hook 3 at its ends and a connection loop 2 in the center. Its arms are provided with a loop 2 of tie rods along the length.

 The end rod D is provided with a hook 3 at its ends and a loop 2 of tie rods along its length.

 One of the hooks 3 of the end rod is connected to the central loop 2 that of the other end 3 to the wire mesh end panel of the gabion.

These four elements are connected and articulated by the hooks 3 in the connection loops 2 shown in Fig 2
The stirrup A is attached to the fabric of the bottom of the gabion by its hooks 1 trapping the strands of the metal fabric so that it articulates freely.

By the play of joints 1-2-3- the device lends itself to its folding to be extended on the bottom of the gabion in which it is incorporated Fig 3 and Fig 4
your figures & 6 page 2/2 characterize the connection frame in its application.

Claims (3)

 1. Connection and reinforcement frame incorporated in the metal gabion for instantaneous use by the plumb and the rigidity of the gabion box, characterized by the incorporation of its articulated elements on the loops (2) folded between the folds of the gabion and retained thereon by the hooks of the stirrup (1).  2. Armature according to claim 1 characterized by the lifting of its elements fixed on the bottom of the gabion and the development of its arms to secure by the hooks (4) the relevant faces of the gabion.  3. Reinforcement according to claim 2 characterized by its arms, the loop (3) of which passes the longitudinal tie rods and serves as attachment points for the transverse tie rods necessary for the consolidation of the gabion.
