Description
Technical field
The utility model relates to the metal reinforcement that uses in a kind of cement concrete in road and bridge engineering, construction work, the bituminous concrete, specifically, relates to a kind of reinforcement and plays the button net with reinforcing bar in length and breadth.
Background technology
Tradition reinforcing bar web frame spare is to shut out pit by the mesh distance separately on longitudinal and transverse reinforcing bar, and the pit braiding between the longitudinal bar odevity of cross reinforcement skip draft is in place, is commonly called as and dials the flower net.Because right-angled intersection place of longitudinal and transverse reinforcing bar is only dialled mutually by very shallow pit on the reinforcing bar and leaned on, wire side is loose, only is used for mesh apart from little net sheet so dial the flower net.
For fear of the problems referred to above, steel mesh reinforcement is mainly following making form at present:
One, the artificial Peng net of wire-tiing, operation is at the construction field (site) arranged by cun requirement of mesh carpenters square longitudinal and transverse reinforcing bar and to be put on the plane, use soft steel wire at place, longitudinal and transverse muscle crosspoint then, is fixed by the method for artificial Peng bundle.Its defective is, the wire-tie mesh of net of artificial Peng is inhomogeneous, and wire side is loose, the time the wrong Peng phenomenon of the Peng of leakage is arranged, the expense of taking a lot of work material, on-the-spot confusion, the peeling force between particularly longitudinal and transverse muscle is very little, single reinforcement tensile strength has only 320Mpa, peeling force is 200N between longitudinal and transverse muscle.
Two, welded wire fabric is by welding machine special, longitudinal and transverse muscle infall is carried out the electric resistance welding welding form.Its advantage is that solder joint is firm, wire side is neat, can produce by the batch production streamline, is convenient to accumulating.Shortcoming is that factory cost is higher, and need there be the lifting facility job site; Easily there is the weldering of leakage sealing-off phenomenon at the solder joint place, and only adapts to welding low-carbon reinforcing bar material.The single reinforcement tensile strength of welded wire fabric is 550Mpa, and the solder joint shearing resistance is 1KN.
In addition, along with the workmanship index promotes, especially in special engineering, for example large bridge, speedway foundation pad, the low-carbon (LC) steel mesh reinforcement is incompatible, and the material and the net making process of steel mesh reinforcement proposed new requirement.Domestic have only several families application medium and high carbon steel material to make the steel mesh reinforcement mother metal at present, can improve concrete component intensity, reduce the steel use amount, the physical dimension of pressurized water cement concrete, bituminous concrete, make single reinforcement tensile strength be increased to 1500Mpa, the solder joint shearing resistance is increased to 2KN.Therefore, use medium and high carbon steel and make mother metal making high strength cast iron net, promoted product up-gradation; And on the other hand, place, the crosspoint of welded wire fabric is the solder joint that forms through welding, the stress concentration phenomenon can occur.Because medium and high carbon steel increases to some extent than mild steel phosphorus content, when welding, solder joint sharply rise in room temperature (about 1400～1600 ℃), the time of staying short (about 0.02～0.05 second), after sharply descend again, cooling rate makes austenite inhomogeneous soon, and crisp hard martensitic structure cold crack appears in heat affected zone easily to low-temperature transformation the time.Because hardness improves, plasticity ratio reduces, and pad fatigue strength is reduced, and the brittle failure phenomenon occurs, and this also is that medium and high carbon steel is one of hard defects of the mother metal steel mesh reinforcement that uses industrial frequency electric resistance weldering mode.
The present domestic steel mesh reinforcement that uses medium and high carbon steel to make as mother metal is used three times conventional power supply welding methods of welding substantially
(being preheating, welding, tempering) trial production.But under the condition of this welding process requirement strictness, product has still the time brittle failure phenomenon to take place.In case extensive the operation, welding machine of mesh is changed and ambient temperature effect by voltage ripple of power network, electrode pressure, the operator is difficult to essential condition such as instant adjustment and guarantee technic index again, and long-distance transport in addition, Week change, all multifactor influences of extruding, and the pad brittle failure will be even more serious.
The utility model content
The technical problems to be solved in the utility model provides a kind of be fixedly connected reinforcing bar in length and breadth of form of right-angled intersection place that improves and plays the button net, can significantly improve the peeling force between the longitudinal and transverse muscle, having solved application medium and high carbon steel, low-alloy steel is the intensity raising requirement of mother metal steel mesh reinforcement, remove the pad brittle failure quality problems of quenching and causing from, and be also more guarantee of mother metal with mild steel because of welding.
In order to solve the problems of the technologies described above, the utility model is achieved by following technical scheme:
A kind of reinforcing bar is in length and breadth played the button net, longitudinal bar and cross reinforcement by mutual vertical arrangement constitute net surface structure, right-angled intersection place of described longitudinal bar and described cross reinforcement is provided with " 8 " font Wan button, described " 8 " font Wan button is for being enclosed within the split ring at one group of diagonal angle of described right-angled intersection place, and the reverse sth. made by twisting in the both ends of described split ring is fixed in described right-angled intersection place both sides.
Described " 8 " font Wan button is isometrical with described longitudinal bar and described cross reinforcement.
