Description
Technical field
This utility model relates to pre-cast building equipment technical field, a kind of threaded fixing
Formula straight thread grout sleeve.
Background technology
Along with assembled architecture development at home, rebar connecting technology also reaches its maturity.On market
The fixed form of existing grout sleeve mostly is the sleeve barrel fixing device location that natural rubber makes, and
The expansion relying on rubber prevents concrete mortar from entering, but this kind of mode is fixing loosely, and grouting set
Cylinder is internal is easily accessible cement mortar.Existing machinery processing grout sleeve pagoda joint assemble time be
Being screwed on the screw thread of curved surface, be difficult to operation, packaging efficiency is low.Inner barrel groove and slurry outlet position
Put coincidence, affect the stress performance of splice.
Utility model content
The purpose of this utility model is to provide a kind of threaded fixed straight thread grout sleeve, adds
Work is simple, and packaging efficiency is higher, and stress performance is good, and is had well by the steel plate of screw thread Yu mould
Fixing, prefabricated components concreting process will not pour into mud from fixing end.
To achieve these goals, the technical solution adopted in the utility model is:
A kind of threaded fixed straight thread grout sleeve, is provided with pulp including cylinder and cylinder
Hole and grout hole are screwed together with pagoda joint, and cylinder one end arranges bar connecting termination, the other end
It is provided with female thread.Axially disposed curved surface chamfering around slurry outlet and grout hole on cylinder body outer wall.
The beneficial effects of the utility model are:
1, cylinder grout hole one end that this utility model uses is threaded, and the other end arranges reinforcing bar
Connection end.Cylinder is connected with the screw thread of sleeve barrel fixing device by screw thread, thus is fixed to perforate
Mould steel plate on.This kind is threaded connection fixed mode to be made fixing more firm, and
Fundamentally solve the defect of spillage when grout sleeve fixes after-pouring concrete.
2, axially add along grout sleeve joint around grout hole of the present utility model and slurry outlet outer wall
Work curved surface chamfering, making pagoda joint is a contact plane when being screwed into, and processing ease is convenient.From
And increase the efficiency of pagoda joint assembling, time-consuming.
3, inner barrel groove location and grout hole, slurry outlet position are avoided in design of the present utility model
Being equipped with coincidence, thus avoid stress dangerous spot wall thickness and reduce, stress performance is reliable.
4, inner barrel groove two ends of the present utility model use oblique angle design, convenient processing.
5, pagoda joint of the present utility model uses taper pipe thread, it is simple to assembly and connection.

Specific embodiments
Below in conjunction with saying that this utility model is further described by accompanying drawing and reference.
As shown in figs 1-9, a kind of threaded fixed straight thread grout sleeve, by cylinder 1,
Slurry outlet 4 and grout hole 5 form, and cylinder 1 is respectively equipped with song at grout hole 5 and slurry outlet 4
Surface chamfer 7；Cylinder 1 uses seamless pipe to be made, and the groove 12 on cylinder 1 inwall passes through machine
Tool is processed into.
Cylinder 1 one end arranges bar connecting termination 2, and the other end arranges the fixing use being machined into
Screw thread 6；
Described bar connecting termination 2 is by machining T-type structure.
On the screw thread 6 side wall of cylinder 1, grout hole 5 is set, bar connecting termination 2 sidewall sets
Put slurry outlet 4, grout hole 5 and slurry outlet 4 to be respectively cooperating with pagoda joint 3 is installed.
Female thread 6 end of cylinder 1 screws togather and is provided with fixing device 8；This fixing device 8 one end is cone
Shape structure, the other end is bolt for retainer structure.
Embodiment
At seamless steel pipe sidewall by being machined into the groove 12 of inside, seamless steel pipe is near filling
The end machine-shaping female thread 6 of slurry side, hole 5, grout hole 5 is processed vertically with slurry outlet 4
Curved surface chamfering 7.
As shown in Figure 5, Figure 6, the grout sleeve joint on right side is by the set of female thread 6 with left side
The screw thread of tube fixing device 8 is connected, thus is fixed in mould steel plate 9 perforate.This kind passes through spiral shell
Stricture of vagina connects fixed mode to be made fixing more firm, and it is solid fundamentally to solve grout sleeve
Determine to come off during after-pouring concrete, the problem of spillage.
As shown in Figure 8, existing slurry outlet 4 and grout hole 5 are not provided with curved surface chamfering 7, go out
The two ends of slurry hole 4 and grout hole 5 are half bracket type screw threads；Only rely on when pagoda joint 3 is screwed into
Two contact points 11 are threadeded with slurry outlet 4 and grout hole 5；There are the following problems, relies on
Time two contact points 11 screw togather, pagoda joint 3 and half bracket type screw thread alignment function difficulty,
Also often there is to twist the phenomenon of wrong screw socket, make pagoda joint 3 thread damage, come off when grouting.
As it is shown in fig. 7, increase curved surface chamfering 7 structure, cylinder 1 sidewall is cut out curved surface chamfering 7, i.e.
Machine away slurry outlet 4 and the high-end unnecessary screw thread of grout hole 5 liang, make pagoda joint 3 fall at curved surface
Be more easily aligned slurry outlet 4 and grout hole 5 under the effect at angle 7, when being screwed into pagoda joint 3 with
Slurry outlet 4 is that a disc 10 contacts with grout hole 5, can be threaded into slurry outlet 4 accurately
With in grout hole 5；It is more convenient to operate, and pagoda joint 3 tip is used taper pipe thread, more increases
The convenience that is screwed into.Thus increase the efficiency of pagoda joint 3 assembling, time-consuming.
As it is shown in figure 9, cylinder 1 is internal is provided with multiple groove 12；This groove 12 and grout hole 5,
Slurry outlet 4 layout straggly.Groove 12 once overlaps with grout hole 5 and slurry outlet 4 position, that
Groove 12 destroys the screw thread of slurry outlet 4, and groove 12 overlaps and wall thickness herein can be made herein to reduce,
And then it is unfavorable for that pagoda joint 3 is fixed, cause potential safety hazard；So groove 12 position avoid with
There is coincidence grout hole 5 and slurry outlet 4 position, add the fixation of pagoda joint 3, make whole
Individual grout sleeve joint stress performance is reliable.Employing oblique angle, groove 12 two ends 13 designs, it is simple to add
The walking linking of cutting tool, convenient processing during work.
