Abstract

The invention relates to a reinforcing netting (1) consisting of welded mesh of welded longitudinal (2) and transverse (3) wires, in which the mesh has indents (4) for fixing the mesh to the wall. The mesh is generally flat and large flat surfaces are present between two adjacent rows of indents (4).

Description

Welded mesh

The invention relates to a reinforcement network consisting of longitudinal and transverse welded wires, especially used for tunnel constructions, in which the mesh has slits to fix the mesh to the wall that is going to be covered.

Such reinforcement network is for example known from the European patent 059466.

The use of welded mesh for reinforcement or Concrete framework is generally known. This is among others the case for the reinforcement of walls in the construction of tunnels. It is also known to make indentations in this welded mesh to give it a three-dimensional shape and to fix it with the grooves to the wall that has to be reinforced or covered.

Both patents US-A-6,079,172 and FR-A-2 523 620 describe a network of welded mesh reinforcement of longitudinal and transverse wires soldiers, in which the mesh has slits to fix the mesh to Wall. The grooves are trapezoidal.

The invention seeks to provide a network of reinforcement that can be fixed easily and quickly to the wall that goes To be covered.

In addition, the invention seeks to provide a new type of reinforcement network, which offers reinforcement excellent concrete or mortar with a minimum of reinforcing materials

Therefore the invention proposes a network of type described in the opening lines where the grooves are of trapezoidal shape, where the mesh is generally flat and where large surfaces are present between adjacent rows of slits These large surfaces have a width which is substantially greater than the width of the grooves.

In a preferred embodiment of the network according to the invention the small base of the trapezoidal grooves consists of two transverse wires that are located at one Small distance from each other.

Preferably, the depth of the grooves trapezoidal is larger than the small base of the indentations trapezoidal

The reinforcement network according to the invention It can be used for mortar or concrete reinforcement. The trapezoidal grooves are used to fix the net to a wall the which is going to be covered with mortar or concrete.

The invention will be further explained in the following description by accompanying drawing. At drawing, figure 1 shows in perspective a part of a mesh in welded network form 1 according to the invention.

The mesh 1 consists of longitudinal wires 2 and transversal 3 soldiers. The meshes of welded net 1 are practically square or rectangular. The wires Longitudinal and transverse 2, 3 are preferably made of stainless steel.

Mesh 1 has at regular intervals slits 4, which are practically trapezoidal. Clefts trapezoidal 4 extend the entire width of the mesh 1.

The small base of the trapezoidal grooves 4 consists of two transverse wires 5 that are located at one Short distance from each other. An important advantage is that the mesh 1 can be easily and quickly attached to the wall that is going to be cover, for example in the case of the construction of a tunnel, by middle of these two transverse wires 5, just ensuring that the fixing means hold both transverse wires 5.

Preferably, the depth of the grooves trapezoidal 4 is larger than the small base of these grooves Four.

The welded net meshes are for example of approximately 50 square mm, in which the distance between the two transverse wires 5 total approximately 12 mm and the depth of the grooves 4 approximately 16 mm. These dimensions only have an indicative character.
