Description
Technical field
The present invention relates to interconnect the reinforcing bar connector for the reinforcing bar of concrete steel building, relate in particular to as connecting along its length the connection end of two notched barss, improvement can two side directions accommodate notched bars reinforcing steel bar connecting device structure and adhesion and improve intensity, to complete easily rapidly the connection operation of notched bars at operation field, thereby raising application property, saves the high-strength Steel Bar Coupler of the expense of production.
Background technology
Generally speaking, concrete is the composite parts being mixed in the proper ratio by cement, sand, rubble, water etc., although its compressive strength is higher, because of its hot strength than compressive strength very a little less than, thereby easily chap.For improving above-mentioned concrete hot strength, after the reinforcing bar that interweaves in the mould of concreting, build, thereby improve concrete intensity.
Compressive strength and the hot strength of existing just your concrete structure are like this good, not only can be used for various forms of buildings, and, because its physical characteristic is very good, be widely used in various buildings and civil engineering.
Reinforcing bar for steel concrete has circular reinforcing bar and notched bars, and circular reinforcing bar refers to that rebar surface is without the reinforcing bar of joint, and notched bars refers to the reinforcing bar of joint and rib (rib).Notched bars larger than circular reinforcing bar with concrete adhesive power, and, while there is be full of cracks on concrete, dwindle the width of be full of cracks, therefore, post reinforcing bar is not generally used circular reinforcing bar and uses notched bars.
The kind of reinforcing bar has five kinds of two kinds of circular reinforcing bars (SBC) and notched barss (SBD).If there is no special requirement, the length of reinforcing bar is generally 3.5～10.0m, if but have special demand, also can produce the product of 6～12m.Circular reinforcing bar refers to that rebar surface is without the reinforcing bar of joint, and notched bars has referred to joint and rib, and axially form be referred to as rib, and along the circumferential direction form, be referred to as joint.Notched bars larger than circular reinforcing bar with concrete adhesive power, and, while there is be full of cracks on concrete, dwindle the width of be full of cracks.
Generally speaking, post reinforcing bar is not used circular reinforcing bar and uses notched bars.The diameter of notched bars and cross-sectional area represent with nominal diameter and nominal cross-sectional area.Nominal diameter refers to the weight circular reinforcing bar identical with notched bars of hypothesis unit length, and its diameter is referred to as to nominal diameter, and the cross-sectional area of calculating nominal diameter is referred to as nominal cross-sectional area.The coefficient of elasticity of reinforcing bar is 200 4 ten thousand kg/cm
2, linear expansion coeffcient is about 1.2 * 10
-5/ ℃, almost identical with concrete.
For forming the mould of the concreting of prior art, notched bars need to be arranged in to the reinforcement placement operation of certain forms, and because of notched bars be generally made into normalization length product, therefore, when carrying out reinforcement placement operation, need to interconnect the operation of the notched bars of certain length, and prior art connecting method for reinforcing bars mainly overlaps connection method, is welded to connect method, bolted-on connection, linkage connection method etc.
Overlap joint connection method is to be wound around the interconnective method of iron wire in the mutual end of the notched bars of stack, although reinforcement placement operation ratio be easier to because need to be wound around each notched bars, not only operation is loaded down with trivial details, and, a little less than the bending strength because of coupling part, easily cause safety problem.
In addition, the method for being welded to connect is the method that weld the end of docking notched bars, although the intensity of coupling part is fine, operation is loaded down with trivial details, and length consuming time is delayed the duration.Bolted-on connection is in the interconnective method of the connection end of notched bars processing bolt, but not only needs the equipment of processing connection end, and, can not constructing at narrow space.
In addition, linkage connection method is to utilize linkage to interconnect the method at the both ends of notched bars, and prior art is because of the video picture of the reinforcing bar shake that deforms in linkage inside, thereby reduces the tensile force of steel concrete, in addition, the number of components that forms linkage is many, complex structure, and production cost is high, operation length consuming time, thereby not only delay the duration, and human cost is too high.
In addition, a touch reinforcing bar connector of the disclosed registered patent 10-0973437 of the inventor, because use spring in connector lock, existing problems aspect bond strength, thus need high-intensity adhesion.
