Just, described below " on ", the upper and lower direction of D score and accompanying drawing consistent, but this can not become technical solution of the present invention
Limit.
Embodiment one
The structure composition of the fixed grout sleeve of the present invention is described in detail referring to figs. 2 to Fig. 5.
A kind of fixed grout sleeve, for adjacent prefabricated components 1 and the connection of prefabricated components 2 20, fixed
Grout sleeve 30 includes a hollow cylindrical cylinder, and the barrel of fixed grout sleeve 30 is longitudinally divided into the two of fixing connection
Part, a part is the end of thread, and another part is to be covered with perforate on tunneling boring perforate end, the i.e. barrel of another part, fixed
The end of thread of grout sleeve is sheathed on outside the reinforcing bar 21 of prefabricated components two, and the two is mechanically connected and forms node one, fixed filling
The tunneling boring perforate end of slurry sleeve is sheathed on outside the reinforcing bar 11 of prefabricated components one, and makes reinforcing bar 11 and the joint of prefabricated components one
Point one forms steel bar connecting joints in being overlapped in fixed grout sleeve, grouting material pouring steel bar connecting joints makes prefabricated components
1 and prefabricated components 2 20 be 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.First reinforcing bar 21 machinery with prefabricated components two of the end of thread using fixed grout sleeve 30 connects
Connect formation node and in the lump the reinforcing bar 11 of prefabricated components one is sheathed on the perforate end formation steel bar connecting joints of grout sleeve 30, so
Rear erection template 40, more whole steel bar connecting joints entirety is watered grouting material so that prefabricated components 1 and prefabricated components two
20 form an entirety.In the embodiment of the present invention, the perforate end of fixed grout sleeve 30 is the design of tunneling boring perforating, the most solid
The lateral wall of fixed pattern grout sleeve 30 perforate end all offers hole continuously or discontinuously, so enable to grouting material without
The hole needing pulp inlet and be directed through on fixed grout sleeve 30 to the node one within fixed grout sleeve 30 and
Steel bar connecting joints grouting cast, it is ensured that the density of concrete cast and adequacy.Certainly, treat that grouting material reaches to design requirement
Rear form removal 40, so that the reinforcing bar 11 of prefabricated components one and the reinforcing bar 21 of prefabricated components two and fixed grout sleeve
The end of thread of 30 and perforate end form a super high strength concrete node under the effect of grouting material, thus complete prefabricated components one
10 and the connection of prefabricated components 2 20.
It is preferred that for the adequacy ensureing grouting so that the fully wrapped around reinforcing bar of perforate end of fixed grout sleeve 30
Connecting node, the length of fixed grout sleeve 30 perforate end is more than or equal to the length of steel bar connecting joints.
Especially, internal diameter 5mm～10mm bigger than the maximum outside diameter of node one of fixed grout sleeve 30, such that it is able to fill
Divide grouting, 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
Form a complete entirety.
Certainly, in order to draw materials conveniently, fixed grout sleeve 30 can be made by common foundry goods grout sleeve.The most just
It is to say, by offering constant aperture in fixed grout sleeve 30 one end barrel (tunneling boring perforate end) according to constant spacing
Form the fixed grout sleeve of the embodiment of the present invention.Such as, in order to easy to make, save and make man-hour, can be in common casting
Part grout sleeve one end barrel is with constant spacing as 1.5cm～2cm offers the constant aperture hole as 1cm.
Embodiment two
Please continue to refer to Fig. 2 to Fig. 5, describe the using method of the fixed grout sleeve of the present invention in detail.
The using method of a kind of fixed grout sleeve comprises the steps:
One, provide some fixed grout sleeves 30 standby, the end of thread of fixed grout sleeve is sheathed on prefabricated structure
Outside the reinforcing bar 21 of part two, the two is mechanically connected and forms node one, and node one is positioned at the reserved groove 12 of prefabricated components one, with
Time the tunneling boring perforate end of fixed grout sleeve is sheathed on outside the reinforcing bar 11 of prefabricated components one, and make prefabricated components one
Reinforcing bar 11 be overlapped in fixed grout sleeve 30 with node one in 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 into a mould steel bar connecting joints by dustpan mouth 50, grouting material is through fixed simultaneously
The hole of grout sleeve 30 enters the complete paired node of inwall one and the cladding of steel bar connecting joints.
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 fixed grout sleeve of the present invention, use the end of thread of fixed grout sleeve 30 first with prefabricated
The reinforcing bar 21 of component two is mechanically connected the formation node reinforcing bar 11 in the lump by prefabricated components one and is sheathed on the perforate of grout sleeve 30
End forms steel bar connecting joints, then sets up template 40, more whole steel bar connecting joints entirety is watered grouting material so that be prefabricated
Component 1 and prefabricated components 2 20 form an entirety.In the embodiment of the present invention, the perforate end of fixed grout sleeve 30 is complete
Section perforating designs, and the lateral wall of the most fixed grout sleeve 30 perforate end all offers hole continuously or discontinuously,
So enable to hole that grouting material is directed through on fixed grout sleeve 30 without pulp inlet to fixed grouting set
Cylinder node 1 30 within and steel bar connecting joints grouting cast, it is ensured that density that concrete is poured into a mould and adequacy.Certainly,
Form removal 40 after design requires is reached until grouting material, so that the reinforcing bar 11 of prefabricated components one and the reinforcing bar of prefabricated components two
21 and the end of thread of fixed grout sleeve 30 and perforate end under the effect of grouting material, form a super high strength concrete joint
Point, thus complete prefabricated components 1 and the connection of prefabricated components 2 20.The using method of this fixed grout sleeve is easy, tool
There is preferably promotional value.
Foregoing description is only the description to present pre-ferred embodiments, not any restriction to the scope of the invention, this
Any change that the those of ordinary skill in bright field does according to the disclosure above content, modification, belong to the protection of claims
Scope.
