Abstract
The utility model discloses a foldable reinforcing steel bar net, which is most applicable for the support of mine roadway rock crusher layer, including basic reinforcing steel bar nets; several basic reinforcing steel bar nets are connected with each other, and chain link components are arranged between the several basic reinforcing steel bar nets; flange girth barbs are arranged at the lower end of the basic reinforcing steel bar nets. Compared with the existing techniques, the utility model improves the overall performance of supporting structure so as to meet the supporting requirements needed by wall rock conditions such as complexity, fragmentation, sludging and so on. The utility model has the advantages in that the basic reinforcing steel bar nets have a high stiffness and intensity; meantime, the integrality and the support effect are perfect; in addition, the foldable chain link structure are easy to be formed and can cling at the rock surface; moreover, the length of the basic reinforcing steel bar nets can be adjusted neatly according to practical needs and the reduplicative superposition can be avoided; at last the invention also has the advantages of a firm connection; simple construction; continuous use; material saving; small size; easy to be transported by a tramcar and extensive practicability, etc.
Description
Technical field
The utility model relates to a kind of collapsible steel mesh reinforcement, is particularly useful for the supporting of mine laneway catalase layer.
Background technology
The laneway molding initial stage, explosion when being subjected to out the lane, machinery or artificial disturbance owing to country rock, surrounding rock failure is serious, 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 time and space, aggravated the fragmentation of deep rock mass again, thereby it is large-area blank to cause chain reaction to form, causes supporting and protection structure to lose efficacy, can cause tunnel large tracts of land roof fall when serious or collapse and emit, threaten the safety of Coal Production.At this problem, general at present employing pool material, prefabricated cement board, diamond mesh or monolithic steel mesh reinforcement carry out supporting.Though they can both play certain support action, because the supporting intensity of pool material and prefabricated cement board is not enough, integrality is bad, easily loses to leak with neutral gear and emits, and can not play effective maintenance effect; Though the diamond mesh globality is better, insufficient rigidity easily forms at broken argillization band weighs down pocket, bloated tripe, causes the supporting inefficacy; 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, destroy earlier in lap-joint easily behind the stand under load, greatly reduced supporting intensity, bring very big trouble and potential safety hazard to site operation.
Summary of the invention
Technical problem: the purpose of this utility model provide a kind of simple in structure, intensity is high, construction simple and fast, collapsible steel mesh reinforcement that supporting effect is good.
Technical scheme: a kind of novel foldable steel mesh reinforcement of the utility model, it comprises basic steel mesh reinforcement, a plurality of basic steel mesh reinforcements are linked together, be provided with the chain type connecting elements that it is connected as a single entity between a plurality of basic steel mesh reinforcements, the basic online bottom of reinforcing bar is set to edge of a wing barb.It is online that described chain type connecting elements can be articulated in basic reinforcing bar, also can be welded on basic steel mesh reinforcement; Described chain type connecting elements can be used anchor chain, also can use handle.
Beneficial effect: a kind of novel foldable steel mesh reinforcement of the utility model is best suited for the supporting of mine laneway catalase layer.Adopt a plurality of basic steel mesh reinforcements are flexible coupling together, the steel combination that soften, problem is emitted in the leakage that has solved in broken, the weak surrounding rock supporting, has overcome the bob pocket that diamond mesh causes owing to insufficient rigidity, bloated tripe phenomenon; Effectively avoided pool material strength deficiency, the shortcoming that integrality is bad; For speedy drivage provides effective means, for Safety of Coal Mine Production provides powerful guarantee; Improve the overall performance of supporting and protection structure, satisfied wall rock conditions such as complicated fragmentation, the argillization supporting demand that goes down into a mine.This metal dictyosome rigidity is big, the intensity height, and integrality is good, supporting effect is good, and the chain type syndeton has foldability, is easy to moulding, can be close to scar, can increase and decrease steel mesh reinforcement length according to actual needs flexibly, overlap joint firmly, easy construction, it is overlapping to have avoided connecing stubble, can use continuously, economical with materials, volume after folding is little, is easy to the mine car transportation, has practicality widely.
Description of drawings:
Accompanying drawing 1 is the collapsible steel mesh reinforcement structure chart of the utility model.
Among the figure: basic steel mesh reinforcement-1, chain type connecting elements-2, edge of a wing barb-3.
The specific embodiment
Below in conjunction with accompanying drawing an enforcement of the present utility model is further described:
A kind of collapsible steel mesh reinforcement of the utility model, it is made of basic steel mesh reinforcement 1 and chain type connecting elements 2, according to on-the-spot Len req, a plurality of basic steel mesh reinforcements 1 are connected to an integral body by chain type connecting elements 2, chain type connecting elements 2 can adopt anchor chain to connect, also can adopt handle to wear the fastening connected mode of overlap joint, chain type connecting elements 2 can be articulated on the basic steel mesh reinforcement 1, also can be welded on the basic steel mesh reinforcement 1, effectively improve the integrality and the validity of surrounding rock supporting structure, integrality advantage with large stretch of reinforced mesh, flexible again folding, be close to scar and reduce net rear space raising compactness, improve the breaking surrounding rock supporting condition, volume after folding is little, and convenient in carrying is easy to the mine car transportation; Folding steel mesh reinforcement is reusable, economical with materials and supporting expense.Basic steel mesh reinforcement 1 upper and lower end parts is set to edge of a wing barb 3, and it is firm to be convenient to supporting, improves maintenance effects, for frame canopy, bolting with wire mesh etc. provide effective technical support.
