Description
Technical field
The present invention relates to construction engineering technical field, specifically a kind of fabrication and installation method of prefabricated sandwich wallboard.
Background technology
General, with the progress of building trade science and technology, architectural industrialization has turned into the inexorable trend that building trade is changed.
The main application product of architectural industrialization has：Precast stair, truss superimposed sheet, prefabricated outer wall panel, prefabricated lining, prefabricated air-conditioning plate
And prefabricated balcony etc..Prefabricated outer wall panel mounting technique is applied to big mode structure prefabricated outer wall panel installing engineering in Side fascia.It is existing
The duration of prefabricated panel under technology is oversize, it is impossible to good cooperation monolithic architecture construction, is brought necessarily to monolithic architecture engineering
The influence of degree.In order to eliminate the influence in terms of these, it would be highly desirable to which demand behaviors meet the prefabricated sandwich wall of modern architecture standard
The fabrication and installation method of plate.
The content of the invention
The technical assignment of the present invention is that there is provided a kind of fabrication and installation side of prefabricated sandwich wallboard for solution the deficiencies in the prior art
Method.
The technical scheme is that realize in the following manner, the fabrication and installation method of the prefabricated sandwich wallboard is including outer
The construction of leaf wall, warming plate laying, connector are installed, the construction of internal lobe wall, maintenance, the demoulding, handling, each processing step is specifically：
A, the construction of siphonal lobe wall：
Process flow：Die station and mold cleaning → siphonal lobe wall mould positioning and assembly → brushing releasing agent → siphonal lobe wall reinforced mesh
Enter mould → built-in fitting positioning, installation → siphonal lobe wall concreting → to vibrate；
（1）After the completion of die station and mold cleaning, rubble, wall brick or chamfering bar can be installed according to production requirement；
（2）The thickness of outer concrete should provide covering cover to reinforcement enough, and meet the enough anchorage lengths of connector；
（3）Slump before concreting should be controlled in 130~180mm；Slump can be by adding in concrete proportioning
Enter water reducer；
（4）Outer concrete maximum cobble-stone diameter should be within 20mm；
（5）Surface is closed flat after vibratory compaction；
B, warming plate laying：
After the completion of siphonal lobe wall concrete-face closure, warming plate laying work can be carried out in plane by being vibrated in siphonal lobe wall；
（1）According to set typesetting form warming plate should be put from one end of wallboard to other end order；
（2）After first warming plate is put well, next warming plate is placed on above previous plate and then design attitude is slided into simultaneously
Immediately preceding one, to prevent concrete to be splashed into space；
（3）Space is avoided the occurrence of between warming plate；
C, connector are installed
Operating procedure：Connector installation → fastness inspection → gap is filled up；
（1）Install：
After the completion of warming plate laying, connector is inserted on the warming plate in pre-drilled hole immediately, with the part of connector
Depthkeeping degree plastic ferrule closely top to insulation plate surface；Then each connector is reversed 90 °, connector is trampled with pin
The warming plate of surrounding anchors to reinforce the concrete of connector end；In addition, when being incubated plate thickness more than 75mm, it is necessary to use
Concrete flat slab vibrator or special pneumatic vibrator vibrate in warming plate upper surface to each connector；Note connection
The arrangement of part should not intentionally facing one direction, preferably random arrangement；
（2）Fastness is checked：
Temporarily take out the connector near every piece of warming plate corner and centre and check end built-in degree, wet water mortar should cover
Cover the whole surface in all examined connector ends；
If inspection has no problem, connector is turned back in foramen primum and applies local pressure or mechanical oscillation again；If inspection
Look into unqualified, applied more pressure on warming plate or apply more mechanical oscillation on each connector, then the company of reexamining
Fitting periphery it is larger range of it is all close on connector, be embedded in ends until cement mortar covers all connectors；
（3）Gap is filled up
On pouring before layer concrete, the warming plate gap more than 3mm, gap and space injection polyurathamc are checked；
D, the construction of internal lobe wall
Process flow：Die station and mold cleaning → internal lobe wall mould positioning and assembly → brushing releasing agent or retarder → internal lobe wall
Bar-mat reinforcement enter the positioning of mould → built-in fitting, installation → internal lobe wall concreting → vibrate → receipts face polishes；
Key control point：
（1）To shorten flow beat, the assembly of internal lobe wall mould, brushing retarder can be carried out in advance, that bar-mat reinforcement enters mould, built-in fitting is fixed
The process that position is installed, when secondary pour on integral hoisting to siphonal lobe wall mould；
（2）The retarder brushing time is at least 30 minutes with the secondary time interval that pours；
（3）Carried out after lower-layer concrete has some strength it is secondary pour, prevent warming plate from floating；
（4）Process of vibrating is forbidden to touch connector；
E, maintenance, the demoulding, handling
Component is secondary pour after the completion of, setting time carries out precuring and steam-cured on request；
During the demoulding, the unnecessary concrete slag of panel edges is removed at utmost to reduce cold-heat bridge, if component is hung out using flat
Mould, should use the first pushing tow component of external force to be allowed to and mould separating, it is to avoid to produce excessive absorption affinity between component and mould and lead
Cause protection damage layer；After the demoulding, washing face is rinsed immediately；
Component rollover, erect after, be transported to stockyard, can be using keeping flat or piling bin assist type is stood up.
The thermal conductivity factor of warming plate is less than or equal to 0.040W/ (mK), and volume ratio water absorption rate is less than or equal to 0.3%.
Warming plate uses extruded sheet.
Produced beneficial effect is the present invention compared with prior art：
The fabrication and installation method of the prefabricated sandwich wallboard applies the division of labor section that sandwich type wall panel is divided into siphonal lobe wall, warming plate and internal lobe wall
Work, and siphonal lobe wall, warming plate and internal lobe wall three are subjected to anchor connection using connector, construct by different level, it is effectively successively solid
Determine siphonal lobe wall and internal lobe wall, position of the warming plate between siphonal lobe wall and internal lobe wall also obtains good fixation, it is to avoid after construction
Dislocation, the generation for the phenomenon such as come off, fracture.
Sandwich type wall panel is operated using prefabricated form of construction work, effectively shortens the duration, construction quality is effectively ensured, it is to avoid be whole
