Description
Technical field
The utility model is related to arrive the realm of building construction more particularly to a kind of energy mortar leakage prevention, improve Grouted density
With the reinforced bar sleeve grouting self-closing apparatus of quality of connection.
Background technology
Critical process of the sleeve grouting technique as prefabrication and assembly construction construction, for reinforced concrete work, steel
The vertical member in the fields such as Structural Engineering, science of bridge building, offshore oil exploiting platform engineering, coastal waters be wind power generation stepped（Such as shearing
Wall and frame column）And horizontal member（Such as Vierendeel girder）Connection, compensating for traditional steel structure connection mode, (main includes welding
Be bolted) deficiency, and obtained rapid development and application.
Grout sleeve is the assembly assembled by the sleeve, mating grouting material and Ribbed Bar specially processed, will be with rib steel
Muscle is inserted into the sleeve of inner cavity with groove, and by injecting special high-strength, contraction-free grouting concrete, coheres occlusion by between material
Effect connection reinforcing bar and sleeve, reach the connection effect higher than parent material of reinforcement rebar intensity.
Due on grout sleeve grouting port or connector nozzle and the matching degree of grouter Grouting Pipe it is not high, junction is deposited
In larger gap, it can lead to spillage or extrusion because of grouting material pressure etc. in filling process, keep concrete surface rough and uneven in surface
Or be difficult to clear up, cleaning work amount and grouting material cost are increased, the compactness and quality of connection of grouting are reduced.
Utility model content
The utility model mainly solves to cause there are spillage phenomenon in existing filling process that Grouted density is high, connection
The bad technical problem of quality；Provide a kind of reinforced bar sleeve filling of energy mortar leakage prevention, raising Grouted density and quality of connection
Starch self-closing apparatus.
In order to solve above-mentioned technical problem, the utility model mainly uses following technical proposals：
A kind of reinforced bar sleeve grouting self-closing apparatus of the utility model, the sleeve for precast reinforced concrete structure are in the milk
Construction, the grouting self-closing apparatus are inserted on the grouting port of grout sleeve, and grouting self-closing apparatus includes the cylinder of two open ends, described
Cylinder is in frustum structure, and bottom is equipped with the shield that multi-disc is in flap-type radiation profiles, and shield is more than in cone sheet, root width
Its top width, shield root are flexibly connected with cylinder body bottom edge, and adjacent shield edge is superimposed with each other, and multi-disc shield, which is constituted, lives
Pyramidal grouting self-closing apparatus is arranged in the closed bottom surface of dynamic formula on grouting port, and barrel is bonded with grouting port, covers slurry casting machine
Edge gap, meanwhile, the shield of multi-clove type can be restored in time again when extracting Grouting Pipe out and closed grouting port, effectively prevent
The generation of spillage, keeps concrete surface smooth bright and clean, ensures the closely knit of sleeve inner slurry, improves the connection matter of reinforcing bar
Amount.
Preferably, the cylinder body bottom is equipped with the retaining sheet of more than one piece annular distribution, the retaining sheet hangs down with cylinder inboard wall
Straight and its side and cylinder inboard wall are affixed, and the bottom edge of retaining sheet is concordant with cylinder body bottom edge, and retaining sheet can guarantee that shield resets
When keep horizontality, prevent due to sleeve inner slurry pressure evagination to destroy closing structure.
Preferably, the cylinder side is equipped with more bracing wires, dial-out grouting self-closing apparatus can be facilitated after grouting.
Preferably, the cylinder and shield are metal material or PVC.
The utility model has the beneficial effects that：Pyramidal grouting self-closing apparatus, barrel and slip casting are set on grouting port
Mouth fitting, covers slurry casting machine edge gap, meanwhile, the shield of multi-clove type can in time restore simultaneously again when extracting Grouting Pipe out
Closed grouting port effectively prevents the generation of spillage, keeps concrete surface smooth bright and clean, ensures the closely knit of sleeve inner slurry,
Improve the quality of connection of reinforcing bar.

Specific implementation mode
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
Embodiment：The reinforced bar sleeve grouting self-closing apparatus of the present embodiment, the sleeve for precast reinforced concrete structure fill
Slurry construction, grouting self-closing apparatus are inserted on the grouting port of grout sleeve, and as depicted in figs. 1 and 2, grouting self-closing apparatus is made of PVC,
Cylinder 1 including two open ends, cylinder are in frustum structure, and bottom is equipped with the shield 2 that multi-disc is in flap-type radiation profiles, and shield is in
Sheet is bored, root width is more than its top width, and shield root is flexibly connected with cylinder body bottom edge, adjacent shield edge phase
Mutually overlapping, multi-disc shield constitute movable closed bottom surface, and the retaining sheet 3 of annular distribution, retaining sheet are equipped in cylinder lumen bottom
And its side vertical with cylinder inboard wall and cylinder inboard wall are affixed, and the bottom edge of retaining sheet is concordant with cylinder body bottom edge, cylinder side
Equipped with symmetrical two bracing wires 4.
In use, the cylinder body bottom for the self-closing apparatus that is in the milk is inserted into the grouting port of grout sleeve, barrel wall face paste is made to close note
The edge of mouth is starched, then, the Grouting Pipe of grouter is inserted into top and the propulsion of cylinder, at this point, as shown in figure 3, slip casting tube head
The matte of the open-top petaloid in portion simultaneously injects in grout sleeve, opens grouter, starts slip casting, when the thick liquid discharge mouth of grout sleeve gushes out slurry
When material, grouter being closed, transfering to Grouting Pipe, the petaloid matte of opening resets again under the grouting material pressure in sleeve to close
It closes, is closed grouting port, prevents the outflow of grouting material, finally, after grouting material tentatively solidifies, pull bracing wire, transfer to grouting self-closing
Device completes reinforced bar sleeve grouting construction.
When as being equipped with connector on sleeve grouting port, then grouting self-closing apparatus can be inserted on the nozzle of corresponding connector,
Carry out above-mentioned grouting construction.
