Description
Technical field
This utility model relates to construction engineering technical field, particularly relates to the knot of a kind of precast concrete bar connecting
Structure.
Background technology
In prefabricated assembled concrete structural construction field in the prior art, generally use the mode of sleeve grouting even
Connect the reinforcing bar of precast concrete.Although existing a variety of sleeves grouting joint in current engineer applied, and its form is many
Plant various, but still suffer from a lot of deficiency；In prior art, by the form of sleeve, full grouting joint and half can be divided into generally
The grouting big class of joint two.The two ends of full grouting joint all use grouting way to connect reinforcing bar, and half grouting joint is general at prefabricated end
Using straight thread mode to connect reinforcing bar, assembled in situ end uses grouting way to connect reinforcing bar；The grouting end of sleeve grouting joint depends on
Reaching Bar Anchorage connection effect by cohering of storeroom, when reinforcing bar tension, pulling force is by reinforcing bar-grouting material faying face
Cohesive action passes to the cohesive action of grouting material, reinforcing bar and grouting material faying face by material adhesive force, mantle friction from reinforcing bar
Mechanical snap power composition between power and rebar surface flank and grouting material, fixes in grouting material performance and rebar surface rib type
In the case of, the cohesive action of unit anchorage length is also certain, in order to provide enough cohesive action to prevent reinforcing bar from filling
Slurry is extracted, enough anchorage lengths need to be set.
But there is a lot of problem demanding prompt solution, example in the one end using straight thread mode to connect reinforcing bar in prior art
As, the processing cost of screw thread is higher and also to ensure the link effect that certain machining accuracy guarantee is stable, and steel
Material component gets rusty easily when storage, and the screw thread impact causing its quality of connection of once getting rusty is huge, then and, screw thread
Connect and easily loosen, thus reduce further its quality of connection.Therefore raising switching performance, reduction processing cost are prior aries
Technical problem urgently to be resolved hurrily.
Utility model content
Because the above-mentioned problems in the prior art, this utility model provides a kind of production cost low, and it is convenient to install
Squash type grouting joint.
For solving the problems referred to above, the technical scheme that this utility model provides is:
A kind of squash type grouting joint, including for connecting the first reinforcing bar and the branch sleeve of the second reinforcing bar, described connection
Sleeve includes socket part and grouting portion, and described socket part is for being tightly sleeved in one end of the first reinforcing bar, and described grouting portion has
Grouting chamber, one end of the second reinforcing bar is stretched into described grouting intracavity, and is fixed on described connection by the slurry of described grouting intracavity
In sleeve.
As preferably, the socket part of described branch sleeve can plastic deformation, the area in the cross section of described socket part is more than
The area in the cross section of the first reinforcing bar, extrudes described socket part and makes its plastic deformation to be tightly sleeved with the first reinforcing bar.
As preferably, the inwall in described grouting chamber is formed with multiple fin or groove.
As preferably, described branch sleeve is configured to integrated formed structure, and the area in the cross section in described grouting portion is more than institute
State the area in the cross section of socket part.
Compared with prior art, the beneficial effects of the utility model are:
Squash type of the present utility model grouting joint need not higher machining accuracy, low production cost, and is easy to
Storage and installation, have higher connective stability.
Accompanying drawing explanation
Fig. 1 is the structural representation of squash type of the present utility model grouting joint.
Reference:
1-reinforcing bar；2-grout hole；3-contraction-free grouting concrete；4-branch sleeve；5-fin；6-slurry outlet.
Detailed description of the invention
For making those skilled in the art be better understood from the technical solution of the utility model, real with concrete below in conjunction with the accompanying drawings
This utility model is elaborated by mode of executing.
As it is shown in figure 1, a kind of squash type grouting joint that this utility model provides, including the connection for connecting two reinforcing bars
Sleeve 4, described branch sleeve 4 includes socket part and grouting portion, socket part can plastic deformation, extrude described socket part and make it mould
Property deformation to be tightly sleeved with reinforcing bar (in figure right side shown in reinforcing bar) 1, described grouting portion has grouting chamber, and reinforcing bar is (left in figure
Reinforcing bar shown in side) 1 one end stretch into described grouting intracavity, and be fixed on described adapter sleeve by the slurry of described grouting intracavity
In cylinder 4.Squash type of the present utility model grouting joint need not higher machining accuracy, low production cost, and is easy to deposit
Storage and installation, have higher connective stability.
Further, the inwall in described grouting chamber is formed with multiple fin or groove, provided by the utility model
In embodiment, fin 5 is ring-type, and by branch sleeve 4 ecto-entad is carried out annular compression formation, good in order to ensure
Bonding strength, described branch sleeve 4 is configured to integrated formed structure, the area in the cross section in described grouting portion be more than described socket
The area in the cross section in portion, and the area in the cross section of described socket part is slightly larger than the area in the cross section of reinforcing bar 1, so that socket part energy
Enough just can be tightly sleeved with reinforcing bar 1 with less deformation, thus reduce the deformation impact on grouting portion further.
During Specific construction, in the element precast stage, first by reinforcing bar 1 (being positioned at the reinforcing bar on right side in Fig. 1) to be connected
Insertion socket part, one end, then utilize extrusion equipment to extrude this socket part, make socket part produce plastic deformation and with reinforcing bar 1 outside
Surface fits tightly, it should be noted that the length of socket part can need to make the appropriate adjustments, certainly, with socket according to different stress
The one end of the reinforcing bar 1 that portion socket-connects can also be configured to end overstriking or other structures, suitably to increase by force intensity and work
Journey demand.Further, grouting chamber is stretched in one end of another reinforcing bar 1 (being positioned at the reinforcing bar in left side in Fig. 1) to be connected, fixing fixed
Position is also sealed (this is prior art common technology means, does not repeats) at this, pours ungauged regions finally by grout hole 2
Grouting material 3 is until stop grouting after slurry outlet 6 overflows, and after contraction-free grouting concrete 3 hardens, the connection of two reinforcing bars 1 just completes
?.
Above example is only exemplary embodiment of the present utility model, is not used in restriction this utility model, and this practicality is new
The protection domain of type is defined by the claims.Those skilled in the art can be at essence of the present utility model and protection domain
In, this utility model is made various amendment or equivalent, this amendment or equivalent also should be regarded as in this practicality new
In the protection domain of type.
