Abstract
A mine supporting metal mesh grid belongs to the protecting net, which is composed of a plurality of horizontal metal bars (1) and a plurality of vertical metal bars (2) and characterized in that the surface of each horizontal metal bar (1) and vertical metal bar (2) is an uneven surface. The horizontal metal bars (1) and the vertical metal bars (2) are in upper and lower staggered braiding to be in the formation of a concave convex surface mesh (3) structure in upper and lower connection. On the concave convex surface mesh (3), the meshes in a rectangular or equilateral shape are formed. The intersection of the horizontal (1) and vertical (2) metal bars is provided with a welding contact (5) for fixed connection. The adoption of this scheme has the advantages that the reinforcing steel bar mesh grid used has stable performance with even stress, high strength and excellent bearing property. The net will not be torn in the networking, thereby the repair of roadway is not required and the input costs of the secondary roadway maintenance can be reduced. With the application of this supporting mesh grid, the roadway driving can be sped up, and the cyclical footage of roadway driving is enhanced. Therefore, the overall support capability of the roadway is improved, and the construction quality of mine roadway is ensured.
Description
Technical field
The utility model belongs to protective screening.It is specifically related to the structure of the metal knitted net of a kind of mining supporting.
Background technology
Along with the mankind's the development and the progress of society, people increase day by day to the demand of coal.But the exploitation in colliery has certain degree of difficulty, if there are not good safeguard procedures to be easy to cause the accident.Mine laneway was subjected to zone of fracture location that geological conditions influences and coal seam to separate the exploitation top that rehearses and adopted diamond mesh, plastic mesh, diamond mesh and plastic mesh etc. mostly in the past.These establishment nets all adopt woven method, produce metallic steel silk and plastic strip earlier, and then be woven into diamond mesh and plastic wire, this series products is because himself performance, the reason of intensity, to soft, net easily hangs down during roadway support under the big condition of fragmentation and roof pressure, intensity is low, influences workmanship.Also do not have at present a kind ofly can overcome exist in the supportings such as original use diamond mesh or plastic wire easily loose, the net that easily hangs down, the low metal knitted net of mining supporting that influences the workmanship defective of intensity.
Summary of the invention
The purpose of this utility model be for overcome that aforesaid ordinary construction protective screening exists to soft, net easily hangs down during roadway support under the big condition of fragmentation and roof pressure, intensity is low, influence the problem of workmanship and be applicable to the coal seam separate zone production work plane top that rehearses more, and water conservancy, special this programme--the metal knitted net of mining supporting that proposes of the needs that engineering bank protections such as highway are reinforced, it uses the reinforcing bar mesh grid to have stable performance, stressed even, the intensity height, advantages such as pressure-bearing property is good, net can not torn during networking, the tunnel is not reprocessed, can reduce secondary maintenance tunnel cost input.
By as above design, the metal knitted net of mining supporting that this programme proposed, be to constitute by many transverse metal bars and many longitudinal metal bars, the surface that it is characterized in that every transverse metal bar and longitudinal metal bar is a convex-concave surface, transverse metal bar and longitudinal metal bar up and down weaving, constituting joins up and down is the male and fomale(M﹠F) network; On the male and fomale(M﹠F) grid, constitute the mesh of rectangle or equilateral shape, be provided with welded contact at the intersection point place of transverse metal bar and longitudinal metal bar and fixedly connected.
Above-mentioned said transverse metal bar and longitudinal metal bar are wavy or shape of threads on the whole.
Be into equidistant (proportional) cross arrangement between above-mentioned said transverse metal bar and the longitudinal metal bar.
The cross section of above-mentioned said transverse metal bar and longitudinal metal bar all can be rounded, square, oval, a kind of in the rectangle.
Above-mentioned said bonding jumper can be in reinforcing bar, iron wire, the band iron a kind of.
Adopt this programme can embody following superiority: (1), the mesh grid of use reinforcing bar have stable performance, and be stressed even, the intensity height, and pressure-bearing property is good.(2), networking the time can not be torn net, and the tunnel is not reprocessed, and can reduce secondary maintenance tunnel cost input.(3), using this net supporting can accelerate to dig lane speed, raising driving cyclic advance.(4), improve the whole support capacity in tunnel, guarantee the mine laneway construction quality, improve degree of safety, further improve site work environment.(5) be colliery Hu Ding, the ideal material that wall supporting rehearses and pushes up, popularizing application prospect is wide.

Above-mentioned said transverse metal bar (1) is wavy or shape of threads on the whole with longitudinal metal bar (2).
Be into equidistant (proportional) cross arrangement between above-mentioned said transverse metal bar (1) and the longitudinal metal bar (2).
The cross section of above-mentioned said transverse metal bar (1) and longitudinal metal bar (2) all can be rounded, square, oval, a kind of in the rectangle.
Above-mentioned said bonding jumper can be in reinforcing bar, iron wire, the band iron a kind of.
Claims (4)
