Abstract
An integrated armour reinforcing bar mesh is applicable to mining, roadway support and rock engineering, and comprises a reinforcing bar mesh made of a plurality of radial and zonal reinforcing steel bars in a cross welding manner. Circular rings with the same size are respectively arranged at two ends of each radial reinforcing steel bar and at two ends of each zonal reinforcing steel bar of the reinforcing bar mesh; the inner bore diameters of the circular rings are larger than the diameters of the radial reinforcing steel bars and the zonal reinforcing steel bars; and center axes of the circular rings of four side edges of the reinforcing bar mesh are on the same straight line. Two adjacent reinforcing bar meshes can be integrally connected through the circular rings on the side edges of the reinforcing bar mesh, thereby enhancing integral support strength, avoiding overlapping connection, saving materials, simplifying construction process and increasing construction efficiency. The size of a single reinforcing bar mesh can be flexibly selected to facilitate long-distance transportation of the reinforcing bar meshes.
Description
Technical field
The utility model relates to a kind of whole mask steel mesh reinforcement, especially adapts to and is used for mining activities, roadway support and geotechnical engineering.
Background technology
In underground construction, after the tunnel became the lane, artificial disturbances such as country rock explosion owing to being subjected to digging the lane, machinery produced destruction, cause top layer, tunnel catalase.If untimely adopting an effective measure, broken sillar can leak from the space of supporting and protection structure and emit, this had both given to continue to leak to emit to destroy provides the space, aggravated the fragmentation of deep rock mass again, thereby it is large-area blank to cause that chain reaction forms, cause supporting and protection structure to lose efficacy, can cause tunnel large tracts of land roof fall or collapse the serious threat coal mine production safety when serious.
At present, domestic general employing pool material, prefabricated cement board, diamond mesh or monolithic steel mesh reinforcement carry out supporting, and the supporting intensity of pool material and prefabricated cement board is low, and integrality is bad, easily lose and produce and Lou emit, and can not play effective maintenance effect; Though the diamond mesh globality is better, insufficient rigidity easily forms bob pocket, bloated tripe at broken argillization band, causes the supporting inefficacy, forms potential safety hazard; Though and monolithic steel mesh reinforcement supporting intensity is higher, it is little that but length is once installed in the influence of the construction technology of being subjected to and supporting parameter, and to frequently overlap, often overlap insecure, it is very inconvenient to construct, at first destroy in lap-joint easily behind the stand under load, greatly reduced supporting intensity, bring very big trouble and hidden danger to site operation.
Summary of the invention
The purpose of this utility model is the deficiency that overcomes prior art, provides a kind of simple in structure, safe and reliable, the whole mask steel mesh reinforcement that supporting effect is good.
For achieving the above object, whole mask steel mesh reinforcement of the present utility model, comprise by many and radially intersect the steel mesh reinforcement be welded into the broadwise reinforcing bar, every of steel mesh reinforcement radially is equipped with the identical annulus of size with the two ends of broadwise reinforcing bar, the internal orifice dimension of annulus greater than radially with the diameter of broadwise reinforcing bar; The central axis of each annulus of four lateral margins of steel mesh reinforcement is on same straight line.
Describedly be welded on that radially the annulus size with broadwise reinforcing bar two ends is identical; Described steel mesh reinforcement dictyosome and mesh are the wide square of array pitch.
Beneficial effect is: whole mask steel mesh reinforcement of the present utility model is easy to connect, annulus by the steel mesh reinforcement lateral margin can connect into adjacent two steel mesh reinforcements as a whole, strengthened the whole supporting intensity of steel mesh reinforcement, it is overlapping to have avoided connecing stubble, saved material, simplify construction technology, improved efficiency of construction; The size of single steel mesh reinforcement can be selected flexibly, is convenient to the long-distance transport of steel mesh reinforcement.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
Fig. 2 is an example structure schematic diagram of the present utility model.
Among the figure: steel mesh reinforcement-1, radially with broadwise reinforcing bar-2, annulus-3, connecting reinforcement-4.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described:
Shown in Figure 1, whole mask steel mesh reinforcement of the present utility model mainly constitutes by radially intersecting the steel mesh reinforcement 1 that is welded into broadwise reinforcing bar 2, and steel mesh reinforcement 1 dictyosome and mesh are the wide square of array pitch.The two ends of every reinforcing bar 2 all are processed with annulus 3, and processing is in that radially annulus 3 size with broadwise reinforcing bar 2 two ends is identical.Make four lateral margins of steel mesh reinforcement 1 that annulus 3 all be arranged, it is closed that the interface of annulus 3 adopts welding to realize.The internal orifice dimension of annulus 3 greater than radially with the diameter of broadwise reinforcing bar 2; The central axis of each annulus 3 of four lateral margins of steel mesh reinforcement 1 is on same straight line.
Shown in Figure 2, connect into the annulus 3 of steel mesh reinforcement 1 lateral margin as a whole by connecting reinforcement 4, the two ends of connecting reinforcement 4, bend to circular, realize the axial restraint of adjacent two annulus, connect thereby adjacent two steel mesh reinforcements can not skidded off from connecting reinforcement 4 along connecting reinforcement 4 relative fixed disconnect.
