Abstract

The utility model relates to a metallic net for rock protection, which is knitted by metal threads or metal cords. A plurality of metal nets (2) and (3) are connected together to form an integral metal net, and the sides which are along the metal nets (2) and (3) are connected with the metal nets (2) and (3) and are provided with steel cables (1) which are intersected from top to bottom to penetrate through grids of the metal nets (2) and (3). The utility model adopts a line connection mode, and thus has high connection strength, and can effectively connect a plurality of metal nets together into a whole and simplify and regulate the connecting process. Consequently, the work efficiency is increased remarkably.

Description

A kind of wire lath that is used for the ground protection

Affiliated technical field

The utility model relates to a kind of wire lath that forms with wire or metallic cable braiding, especially a kind of wire lath that is used for the ground protection.

Background technology

The ground protective screening is a kind of wire lath that forms with wire or metallic cable braiding; the rubble that mainly serves as highway or railway slope wall protects screen or is used to protect the ground top layer, in use needs according to the shape of laying area and sloping wall a plurality of wire laths to be connected together to form the protective screening of an integral body.At present, the mode that the connection of wire lath generally all adopts iron wire to tie up, because this connected mode connects only forming point on the whole fillet between a plurality of grids, so bonding strength is difficult to guarantee, but also exists operation to be difficult for standard and construction does not make, work efficiency is low shortcoming.

The utility model content

Make bonding strength be difficult to guaranteed deficiency in order to overcome the connection of existing metal site, the utility model provides a kind of wire lath of line connected mode, and the bonding strength height between each wire lath can connect into a plurality of wire laths an integral body effectively.

The technical scheme that its technical problem that solves the utility model adopts is: wire lath of the present utility model is formed by wire or metallic cable braiding, and connect by a plurality of wire laths and to be combined to form a bulk metal net, there is cable wire to intersect the grid that passes wire lath up and down along the limit that each wire lath is connected.

The beneficial effects of the utility model are: 1. adopt the line connected mode, and each grid stress equalization of connecting portion, the bonding strength height can connect into a plurality of wire laths an integral body effectively; 2. make connection procedure become simple and standard, and can improve work efficiency significantly.

The specific embodiment

Below in conjunction with drawings and Examples the utility model is further specified.

As shown in Figure 1 and Figure 2, protective metal net of the present utility model, form by metal wire knitted, and be combined into a bulk metal net by a plurality of

wire laths

2,3, there is cable wire 1 to intersect the grid that passes

wire lath

2 and 3 up and down along the limit that

wire lath

2,3 is connected, realize that the line between each wire lath connects, thereby make each grid stress equalization of connecting portion.

Described cable wire 1 can be a steel cable, also can be steel wire.

Described cable wire 1 intersects the grid that passes

wire lath

2 and 3 fillets up and down dual mode, and a kind of is to pass with linearity, and when adopting this mode,

wire lath

2 and 3 fillet will overlap; Another kind is to pass with the spiral surrounding shape, and when adopting this mode,

wire lath

2 and 3 fillet can overlap also and can not overlap.

The two ends of described cable wire 1 are connected with fastening anchor 4.The effect of fastening anchor 4 is after cable wire 1 tensioning it to be anchored on the rock-soil layer.

Go back segmentation on the described cable wire 1 and be connected with fastening anchor 5, thereby increase the stability of bulk metal net.

In each wire lath that connects by cable wire 1, as required fastening anchor 4 or fastening anchor 5 can be set on the wire rope section by some wire lath, then be not provided with on the wire rope section on other wire laths.

Described fastening anchor the 4, the 5th, general or special purpose securing member comprises anchor slab, anchor pole etc.

Below three embodiment are three kinds of different modes that mesh wire connects in the utility model:

Embodiment 1:

wire laths

2,3,

wire lath

2,3 is along the edge lap that is connected, and has cable wire 1 to intersect the grid that passes

wire lath

2 and 3 overlapping parts up and down with linearity on the overlapping part.

The two ends of cable wire 1 are connected with fastening anchor 4.

For increasing the stability of bulk metal net, also segmentation is connected with a plurality of fastening anchors 5 on cable wire 1.

Embodiment 2:

Shown in Fig. 3,4, protective metal net of the present utility model, form by metal wire knitted, and be combined into a bulk metal net by a plurality of

wire laths

2,3,

wire lath

2 and 3 overlapping parts up and down with the spiral surrounding shape on the overlapping part.

Be connected with fastening anchor 4 at the two ends of cable wire 1.

Embodiment 3:

Shown in Fig. 5,6, protective metal net of the present utility model is formed by metal wire knitted, and is combined into a bulk metal net by a plurality of

wire laths

2,3,

wire lath

2,3 does not overlap, and has cable wire 1 to intersect the grid that passes

wire lath

2 and 3 up and down with the spiral surrounding shape along the limit that

wire lath

2,3 connects.

The two ends of cable wire 1 are connected with fastening anchor 4.

For increasing the stability of bulk metal net, go back segmentation on the cable wire 1 and be connected with a plurality of fastening anchors 5.
