Detailed description of the invention
A kind of grout sleeve proposed the present invention below in conjunction with the drawings and specific embodiments and using method are made further
Describe in detail.According to description below, advantages and features of the invention will be apparent from.Hereinafter will be combined by cited embodiment
Accompanying drawing, describes technology contents and the feature of the present invention in detail.Need to additionally illustrate, accompanying drawing all use the form simplified very much and
All use non-ratio accurately, only in order to facilitate, to aid in illustrating lucidly the purpose of the embodiment of the present invention.For sake of convenience, under
Described in literary composition " on ", the upper and lower direction of D score and accompanying drawing consistent, but this can not become the restriction of technical solution of the present invention.
Embodiment one
The structure composition of the grout sleeve of the present invention is described in detail referring to figs. 2 to Fig. 6.
A kind of grout sleeve, for adjacent prefabricated components 1 and the connection of prefabricated components 2 20, grout sleeve 30 wraps
Including a hollow cylindrical cylinder, the barrel tunneling boring of grout sleeve 30 offers hole, the reinforcing bar 11 of prefabricated components one and prefabricated structure
The reinforcing bar 21 of part two is connecting overlap joint connection formation bar splicing node at node, and grout sleeve 30 is sheathed is overlapped in bar splicing
The outside of node forms steel bar connecting joints, and grouting material pouring steel bar connecting joints makes prefabricated components 1 and prefabricated components two
20 are connected to become an entirety.
Specifically, in prefabrication is constructed, prefabricated components are taken by the most reserved reinforcing bar each other
Connect in succession and pour into a mould grouting material concrete and form stable connection, thus form overall structure.In embodiments of the present invention, fill
Slurry is ultra-high performance concrete.Using the grout sleeve 30 reinforcing bar 11 by prefabricated components one and the reinforcing bar 21 of prefabricated components two
Form bar splicing node after having overlapped, then set up template 40, more overall pouring grouting material is to whole bar splicing node
Steel bar connecting joints is formed so that prefabricated components 1 and prefabricated components 2 20 form an entirety after pouring.The present invention implements
In example, grout sleeve 30 designs for tunneling boring perforating, and the lateral wall of the most whole grout sleeve 30 all offers continuously or do not connects
Continuous hole, so enables to hole that grouting material is directed through on grout sleeve 30 without pulp inlet to grout sleeve 30
Internal bar splicing node grouting pours, it is ensured that the density of concreting and adequacy.Certainly, treat that grouting material reaches to set
Meter require after form removal 40 so that the rod member 11 of prefabricated components one and the reinforcing bar 21 of prefabricated components two and grout sleeve
30 form a super high strength concrete node under the effect of grouting material, thus complete prefabricated components 1 and prefabricated components 2 20
Connection.Owing to grout sleeve 30 can be drawn materials conveniently by holing on steel plate or using ready-made expanded metal lath to make, become
This is low, is greatly saved engineering cost.
It is preferred that for the adequacy ensureing grouting so that grout sleeve 30 fully wrapped around bar splicing node, grouting set
The length of cylinder 30 is more than or equal to the length of bar splicing node.
Especially, internal diameter 5mm～10mm bigger than the external diameter of bar splicing node of grout sleeve 30, such that it is able to fully fill
Slurry, it is ensured that the connectivity robustness after the grouting of whole steel bar connecting joints so that prefabricated components 1 and prefabricated components 2 20 are formed
One complete entirety.
Certainly, in order to draw materials conveniently, grout sleeve 30 is rolled by expanded metal lath and forms.Grout sleeve 30 can be according to prefabricated structure
The position when reinforcing bar 11 of part one and the reinforcing bar 21 of prefabricated components two overlap thus the shape of bar splicing node that formed determine,
Such as can be for the cylinder shown in Fig. 3 to Fig. 5 or bicylinder shape or half cone-shaped.Wherein, the grouting set of half cone-shaped
Cylinder design, it is possible to when the reinforcing bar 11 of prefabricated components one and the reinforcing bar 21 of prefabricated components two overlap the most point-blank, it is allowed to
Certain range of error, it is achieved the quick lap joint of two reinforcing bars, thus save overlap joint installation work-hour.
Embodiment two
Please continue to refer to Fig. 2 to Fig. 6, describe the using method of the grout sleeve of the present invention in detail.
The using method of a kind of grout sleeve comprises the steps:
One, the reinforcing bar 11 of prefabricated components one and the reinforcing bar 21 of prefabricated components two are overlapped formation bar splicing node, reinforcing bar
Overlapped joints is positioned at the reserved groove 12 of prefabricated components one, and grout sleeve 30 is sheathed on the outside of bar splicing node simultaneously
Form steel bar connecting joints.
Two, around steel bar connecting joints installation form 40, and reserved dustpan mouth 50.
Three, using grouting material to be poured steel bar connecting joints by dustpan mouth 50, grouting material is through grouting set simultaneously
The hole of cylinder 30 enters inwall and completes the cladding to bar splicing node.
Four, form removal 40 after design strength requires is reached until grouting material.
Further, in order to improve the intensity of steel bar connecting joints, and prefabricated components 1 and prefabricated components 2 20 are reduced
Connecting the size of node, reduce the usage amount being used for pouring into a mould the grouting material concrete of node, grouting material is ultra-high performance concrete
I.e. UHPC.
In sum, the grout sleeve of the present invention, the reinforcing bar 11 of prefabricated components one and the reinforcing bar 21 of prefabricated components two are taken
Form bar splicing node after having connect, then set up template 40, more whole bar splicing node is watered by overall pouring grouting material
Steel bar connecting joints is formed so that prefabricated components 1 and prefabricated components 2 20 form an entirety after filling.The embodiment of the present invention
Middle grout sleeve 30 designs for tunneling boring perforating, it is possible to grouting material is directed through without pulp inlet on grout sleeve 30
Hole within grout sleeve 30 bar splicing node be in the milk cast, it is ensured that concrete cast density and adequacy.
Certainly, reach form removal 40 after design requires until grouting material, so that the rod member 11 of prefabricated components one and prefabricated components two
Reinforcing bar 21 and grout sleeve 30 under the effect of grouting material, form a super high strength concrete node, thus complete prefabricated structure
Part 1 and the connection of prefabricated components 2 20.Owing to grout sleeve 30 can be by holing or using ready-made steel on steel plate
Expanded metals is made, and draws materials conveniently, and low cost is greatly saved engineering cost.The using method of this grout sleeve is easy, has preferably
Ground promotional value.
