1st, it is compared with the extrusion socket joint of prior art, in the case of equal length and wall thickness, of the present utility model
Connector has more preferable bonding strength.Its basic reason is connector of the present utility model and sleeve work of the prior art
Power transfer mode when making is different：In existing sleeve connection, the axial force of reinforcing bar A is by mechanical snap (when being connected using screw thread
When connecing or extrude connection) or the grouting body (when using grouting connection) of consolidation be all delivered to one end of sleeve, recross
The axial centre of sleeve reaches the other end of sleeve, and passes to reinforcing bar B in an identical manner, on the one hand, require reinforcing bar with set
Occlusal contact area between cylinder or grouting body (is presented as the length of sleeve, the length of another sleeve is big with the diameter for being connected reinforcing bar
It is little proportional) it is sufficiently large to prevent both from departing from, on the other hand, it is desirable to the cross section of the minimum of sleeve extruding rearward recess
Product (be presented as the wall thickness of sleeve, and be to extrude to need to undertake all of axial force at the minimum cross-section of rearward recess) foot
Reach big to prevent sleeve breakage；And in connector of the present utility model, a part for the axial force of reinforcing bar A is passed by mechanical snap
Connector side diametrically is passed, the longitudinal center for recrossing connector reaches connector opposite side diametrically, and
Reinforcing bar B is passed in an identical manner, while another part of the axial force of reinforcing bar A then passes through stinging between reinforcing bar A and reinforcing bar B
Close position and be directly passed to B reinforcing bars, first, from from occlusal contact area, when the connector with existing sleeve equal length is adopted,
In this utility model, the length of action of reinforcing bar A and reinforcing bar B and connector is equal to the length of connector, and existing sleeve connection skill
In art, the length of action of reinforcing bar A and reinforcing bar B and sleeve only has the half of length sleeve, although in connector in this utility model
On section, reinforcing bar A and reinforcing bar B is shorter than sleeve of the prior art with the lines of occlusion of connector, but can at least reach existing sleeve
70% so that the occlusal contact area of every reinforcing bar and connector can at least reach percent the 140% of prior art, additionally, this
In utility model, between reinforcing bar A and reinforcing bar B, directly a big chunk load can also be shared in the part of occlusion so that this utility model
Axial load resistant ability be obviously improved；Secondly, from from the sectional area of connector, when using wall thickness identical with existing sleeve
During connector, existing sleeve is that all axial forces are born in cross section, and connector of the present utility model is that longitudinal cross-section is held
By part axial force, and the longitudinal cross-section area of generally sleeve and connector is more much bigger than cross-sectional area, therefore this
The bearing capacity of the connector of utility model is higher, also, connector of the present utility model longitudinal direction in the case of length increase
Area of section also accordingly increases, and the anti-axial force of its axial gmatjpdumamics and longitudinal cross-section is interrelated complementing each other
, and the gmatjpdumamicss of the axial direction of existing sleeve are only related to the length of sleeve, the anti-axial force of lateral cross section only with wall
It is thick relevant, need to meet respective power delivery request respectively.As can be seen here, in the case of equal length and wall thickness, this practicality
New connector has more preferable bonding strength, in other words in the case where equal bonding strength is reached, this utility model
Connector length it is shorter, wall thickness is thinner.

Connector simple production process, quality easily ensure that production efficiency is high, and consumptive material is less, and cost is lower.Connector of the present utility model
In one end relative with circular arc steel plate section be hatch frame, when carrying out extruding connection, the connector is occured bending and deformation first,
Make connector fit with rebar surface, and then detrusion occur again, so needing that impression is relatively shallower, and relative sleeve connection
The wall thickness of part is thinner, and the resistance for therefore suffering from is less, needs the energy for consuming low, more laborsaving, also, to extruding end product quality
Ensure relatively easy, it is possible to reduce because extruding makes the probability of connector cracking.And existing sleeve cross section is tubular structure, it is
One of most strong form in structural mechanics system, and extruding connection when all steel detrusion, in order to reinforcing bar insert
There is certain space length before entering the extruding of sleeve, sleeve and rebar surface, extrude also relatively deep, the required pressure of the impression for requiring
Power and energy ratio even part part of the present utility model are much greater, simultaneously because extruding and causing the probability of sleeve cracking relatively
It is high.For the larger job site of extruding attended operation difficulty, lower, the more labour-saving connected mode that consumes energy obviously can
Reduce difficulty of construction and improve working performance.
3rd, compared with the extrusion socket joint of prior art, attended operation of the present utility model is more prone to.This practicality is new
When two reinforcing bars are connected, the connector of type only requires that two reinforcing bars have the overlap joint overlay segment of certain length, the overlap joint is overlapped
Section can extend, and when connector is buckled into the overlap joint overlay segment, the connection end of two reinforcing bars is from radially into connector
In, therefore difficulty of construction is less, it is relatively also lower to the length requirement of the connection end of two reinforcing bars.And existing sleeve connection
In, during connection, the end of two reinforcing bars alignment sleeve must be entered axially in sleeve, and the connection end of two reinforcing bars is not
Can overlength, can not too short the error of regulation (can not have short across), therefore, constructing operation more strict to the dimensional requirement of reinforcing bar
Difficulty is also larger.
5th, compared with existing interconnection technique, connection reinforcing bar of the present utility model and method of attachment can both apply existing in tradition
Pouring concrete structure can also be applied in fabricated construction, especially apply the advantage in prefabricated construction to become apparent from, both
With overlap joint reinforcing bar easy construction, and while have the advantages that be mechanically connected linkage section it is short, facilitate implementation high prefabricated rate, and
The bar connecting that prior art can not be accomplished or is difficult to carry out can be realized；For example during the two ends bar connecting of predetermined level component,
With the mounted reserved steel bar in the component of both sides, this utility model can realize that mechanical splice is connected simultaneously, and the reserved steel of institute
, less than the length in reserve required for overlap joint, prefabricated rate is high, and the method for attachment of prior art has to adopt at one end for the length of muscle
Connected with frame for movement and adopt in the other end and overlap.
6th, connector of the present utility model is by more direct, path when being delivered to another reinforcing bar of the power of a reinforcing bar
It is shorter, it is more easy to reach the reinforcing bar I levels of pertinent regulations, II level jointing standards；And the dual connection of reinforcing bar, safe and reliable can be realized
Property up to or more than the safe overlap joint standard of the highest to existing pertinent regulations；Such as《Engineering structure reliability design unified standard
GB50531-2008》In one-level safe class standard.
7th, when dedicated extruded mould of the present utility model can make connection, the required energy that extrudes is little, makes connector and reinforcing steel bar machinery
It is tightly combined, and then reduces connector size, makes connection machinery miniaturization become possibility.
