Type quality.
It referring to attached drawing 5-6, is also poured in the prefabricated panel and is fixed with fastener inserts 7, fastener inserts 7 include service sleeve 71
And it is set to the interior built-in fitting 72 in service sleeve 71；Wherein, service sleeve 71 is equipped with multiple groups, and each service sleeve 71 pours respectively
It builds and is fixed in lining 1.Interior built-in fitting 72 is in be arranged in a one-to-one correspondence, and each interior built-in fitting 72 pours respectively with service sleeve 71
It is fixed in corresponding service sleeve 71.Interior built-in fitting 72 is to lift accessory or cable sleeve simultaneously, according to lifting accessory and cable
The difference that sleeve design requires, there is also differences for corresponding service sleeve 71 mode pre-buried in prefabricated panel；Wherein, for hanging
Assembly parts, by taking threaded sleeve as an example, corresponding service sleeve 71, which vertically pours, to be fixed in lining 1, and keeps it away from exterior wall
2 one side opening of plate is unimpeded；For cable sleeve, it is contemplated that the later period wears the demand of cable, and corresponding service sleeve 71 extends vertically through
Entire prefabricated panel.After service sleeve 71 is poured and fixed, each accessory and cable sleeve of lifting is consolidated by concreting respectively
It is scheduled in corresponding service sleeve 71.
The working principle of the present embodiment is:
By pouring the insulation board 3 of fixed extruded polystyrene board material between lining 1 and Side fascia 2, it is greatly improved traditional pre-
The thermal insulation property of wallboard processed；Meanwhile by the way that connector 4 is arranged in 3 two sides of insulation board, insulation board 3 is greatly improved by connector 4
With the bonding strength between lining 1, Side fascia 2；In addition, improving should by pouring fixed fastener inserts 7 in prefabricated panel
The convenience of prefabricated panel lifting and finishing.
Embodiment 2:
Referring to attached drawing 2, a kind of production technology of concrete prefabricated wallboard, comprising the following steps:
S1, mold cleaning: correspondence is selected to pour mold according to design requirement, and it is clean to pour mold cleaning.
S2, mold assembling: mold will be poured and assemble and be fixed in steel platform, and to after being completed pour mold into
Row dimensional gaughing, it is ensured that its size meets design requirement.
S3, release agent is smeared on pouring mold.
S4, die inside installation service sleeve 71 and framework of steel reinforcement 5 are being poured.
S5, lining 1 is poured: according to the design requirement of lining 1 to pouring the coagulation for being poured theoretical cube of amount in mold
Soil, and smooth out its surface after being vibrated repeatedly to concrete；Then, multimetering is carried out to concrete, according to coagulation
The difference of native real-time thickness and 1 design thickness of lining is supplemented or is scraped off part concrete to pouring, and smoothes out its table in mold
Face.
S6, it is laid with insulation board 3: each connector 4 being fixed on insulation board 3 for bolt and nut group 6 according to design requirement
Two sides, and 3 level of insulation board is layed on concrete, so that each connector 4 is embedded in concrete.
S7, Side fascia 2 is poured: the coagulation according to the design requirement of Side fascia 2 to theoretical cube of amount of 3 upper of insulation board
Soil, and smooth out its surface after concrete is vibrated repeatedly on to insulation board 3；Then, multimetering is carried out to concrete,
According to the difference of concrete real-time thickness and 2 design thickness of Side fascia, part concrete is supplemented or scraped off in mold to pouring, and
Smooth out its surface.
S8, it each lifting accessory and cable sleeve is poured respectively using concrete is fixed in corresponding service sleeve 71.
Steam curing is carried out after S9, plastering press polish.
Storage maintenance is carried out after S10, demoulding.
It is outer to reduce in practical operation although fastener inserts 7 include service sleeve 71, lifting accessory and cable sleeve
Influence of boundary's factor for lifting accessory and cable sleeve installation accuracy should first pass through machine frame for pre-buried set in step s 4
Pipe 71 is fixed on the inside for pouring mold vertically, and each service sleeve 71 is made to be located exactly at corresponding lifting accessory and cable sleeve
Design position on；After the completion of step S7, each service sleeve 71 is poured and is fixed in the prefabricated panel.At this point, people again
Each lifting accessory and cable sleeve are inserted into corresponding service sleeve 71 by work, and are poured concrete into its gap；In concrete
Before condensation, artificially adjusts and confirm that lifting accessory and cable sleeve are positioned exactly on its design position；Until concrete is completely solidifying
Knot, lifts accessory and cable sleeve is cast and is fixed in corresponding service sleeve 71.In this way, it can be greatly improved and hang
The accuracy of assembly parts and cable sleeve installation site.
It, should be by multimetering come in real time to guarantee pouring quality in carrying out lining 1 and 2 casting process of Side fascia
The thickness of concrete is detected, and ensures the real-time thickness of concrete with the error of corresponding design thickness within 3mm.Preferably,
Thickness of the concrete before condensation should be made slightly larger than its design thickness；In this way, after concrete coagulation, lining 1 and exterior wall
The thickness of plate 2 can reduce slightly, so that its actual (real) thickness be made to be substantially equal to corresponding design thickness.
In the actual production process, it after the completion of lining 1 pours, before Side fascia 2 pours beginning, needs first in lining 1
Upper laying insulation board 3；At this point, pouring influence of the operation to insulation board 3 to reduce Side fascia 2, first by insulation board 3 and mould can be poured
Tool is fixedly connected, and guarantees the accuracy of 3 paving location of insulation board.Also, in this way, by insulation board 3 by lining 1
It pours operation and pours job separation with Side fascia 2 and come, and lining 1 and Side fascia 2 are carried out respectively to repeat to vibrate, reduce wall
The blocked up influence to effect of vibrating of plate guarantees the density of inside concrete in prefabricated panel, so that it is prefabricated to help to improve this
The structural strength of wallboard.
This specific embodiment is only explanation of the invention, is not limitation of the present invention, those skilled in the art
