Abstract
The utility model discloses a ribbed reinforcing steel bar welded net for buildings, which consists of ribbed reinforcing steel bars that are welded crisscross, and meshes are formed among the ribbed reinforcing steel bars, which are spirally ribbed reinforcing steel bars. Spiral ribs are cold-drawn out of the low-carbon reinforcing steel bar material by adopting the spiral mold drawing technique, so that the holding force of the ribbed reinforcing steel bar welded net on concrete can be enhanced. The tensile strength of the ribbed reinforcing steel bar welded net reaches 800MPa to 1000MPa, increased by 30 percent to 40 percent as against the tensile strength (450MPa to 550MPa) of the hot-rolled and cold-rolled ribbed reinforcing steel bar welded nets and the cold-drawn plain reinforcing steel bar welded net. Steel materials are saved to the max, the cost is reduced, and the ribbed reinforcing steel bar welded net has high rigidity and strong holding force on concrete, cannot be deformed after being formed, cannot easily cause cracks and therefore enhances the structural strength of reinforced concrete, thus ensuring construction quality.
Description
Technical field
The utility model relates to a kind of building unit, relates in particular to a kind of Ribbed Bar welded mesh for building.
Background technology
In engineering construction, often in concrete, put welded steel fabric, to improve concrete intensity, form concrete structure, this welded steel fabric adopts longitudinal reinforcement and transverse reinforcement to be arranged in the right angle with certain spacing respectively mostly, the crosspoint is welded together and form, for the intensity of reinforcing steel bar and concrete combination, reinforcing bar adopts with ribbing usually.Mainly contain hot rolling, Welded Mesh of Cold Rolling Rebar and cold-drawn plain steel-bar net in the market, cold-drawn plain steel-bar net is not because the plain steel-bar surface has indentation, with the little reinforcing bar of the concrete frictional resistance destruction that is drawn out easily.Cold rolled reinforcing steel bar with ribs is a kind of structural steel that late nineteen seventies new development is in the world got up, it is that common low-carbon (LC) hot rolling wire rod is made raw material, roll rib through the cold rolling footpath of feeding, roll into the three distortion section reinforcing bars of wearing cross rib, has higher intensity and plasticity preferably, and characteristics such as bond stress is strong between the concrete, be used for concrete component, not only can save steel, cement, and fundamentally improved cold group of low-carbon (LC) reinforcing bar of light circle because of some quality problems that the bond and anchor property difference causes, improved the security reliability of concrete component.But because it adopts the low-carbon (LC) hot rolling wire rod to make raw material, still have some drawbacks, mainly being that intensity is on the low side can not save steel to greatest extent.Reinforcing bar becomes the medium high carbon reinforcing bar for the content that improves intensity and must increase carbon in the reinforcing bar, manganese, but because the increase of carbon manganese can make the solder joint place of weldering net embrittlement occur, thereby do not reach the requirement of municipal engineering and construction work.
The utility model content
The purpose of this utility model provides a kind of Ribbed Bar welded mesh for building that can further improve its intensity just in order to overcome above-mentioned deficiency of the prior art.
The utility model is achieved by following technical proposals: a kind of Ribbed Bar welded mesh for building, constitute by the crisscross Ribbed Bar that welds together, and form mesh between reinforcing bar, described Ribbed Bar is a spiral ribbed reinforced bar.
Described spiral ribbed reinforced bar diameter is: 3～4mm.
The mesh that forms between described reinforcing bar is rectangle, square, rhombus.
The length of described mesh is: 50～100mm, width is: 50～100mm.
This net is a plain net, nets widely to be: 1000～2300mm; Net length is: 4000～6000mm.
This net is the volume net, nets widely to be: 1000～2300mm; Net length is: 200～500m.
The beneficial effects of the utility model are:
1, low-carbon (LC) reinforcing bar material is adopted the cold-drawn of spiral die drawing silk technology go out spiral ribs, it is increased and concrete bond stress.Tensile strength of the present utility model reaches 800～1000MPa, and the tensile strength 450～550MPa raising 30%-40% than hot rolling, cold rolled reinforcing steel bar with ribs and cold-drawn plain steel-bar welded mesh has saved steel to a greater extent, has reduced cost.Have that rigidity is big, not yielding, strong after the moulding with concrete bond stress, be difficult for producing the crack, improved the structural strength of steel concrete, guaranteed construction quality.
2, spiral ribbed reinforced bar of the present utility model press longitude and latitude and is being arranged on automatic multiple-spot welding machine, and its right-angled intersection point place anneal and switch on resistance welding of pressurizeing is reticulated, and its reinforced steel bar strength reaches 850～1000MPa, and shearing resistance reaches more than the 1500MPa.Every mechanical index of the present utility model reaches medium carbon steel muscle level.Adopt the spiral ribbed reinforced bar of automatic moulding to be welded into net; the whole operations and the 90% above colligation molding procedure of original field fabrication have all been carried out batch production production; except that the quality that has guaranteed reinforcement fabrication, colligation; simplified construction sequence; shortened the construction period of engineering; reduced labour intensity, the noise pollution when having reduced the straightening operation helps environmental protection and civilized construction.Improved building, municipal Product industrialization level, improved production efficiency greatly, factory has been transferred in the tired multiple work of engineering site carry out, saved a large amount of labours, thereby increased economic efficiency.
When 3, the utility model uses the low-carbon (LC) reinforcing bar to change drawing process, before welding, automatic welding machine increases annealing in process at its right-angled intersection point, and the solderability that makes it localized metallic metallographic lattice improves, and has guaranteed that not embrittlement after the solder joint cooling reaches the requirement of the stretching resistance of solder joint simultaneously again.
The utility model is mainly used in the cast-in-situ concrete engineerings such as bridge deck pavement in the municipal engineering and the floor in the construction work, roof, ground, mainly bears the opposing load, prevents the effect of the generation of distress in concrete effectively.
