Specific embodiment
The present invention is further illustrated below by way of specific embodiment.
Between a kind of assembled architecture component and component, the construction method of connecting sewing, comprises the steps：
1st, cast-in-place sleeper reinforcing bar colligation
Different according to precast wall panel species, Side fascia both sides reserved steel bar has following three kinds：The dark depth of beam scope in top reserves dark beam longitudinal reinforcement（YWQ）, the reserved level of body of wall overall height scope is to closed stirrup（YSQ）, and body of wall overall height scope reserve vertical closed stirrup (YNQ), the colligation order of the cast-in-place sleeper variety classes reinforcing bar in its both sides is also had any different.
Shear wall slab（YSQ）Both sides sleeper reinforcement installation
As shown in figure 1, reinforcement installation order：Shear wall slab（YSQ）Lift the vertical muscle of in place → sleeper stirrup installation → sleeper and lacing wire is installed；
After the lifting of precast shear wall plate is in place, the installation of sleeper stirrup is first carried out, according to stirrup spacing, by interim for stirrup colligation on the closing ring of component；Vertical for sleeper muscle is vertically penetrated in stirrup from top, and is connected with the reserved joint bar of next layer of sleeper；Adjustment stirrup spacing, by stirrup and the reliability colligation of vertical muscle；The lacing wire of last colligation sleeper.
2nd, electric wire box, spool are buried
In sleeper reinforcing bar process of binding, coordinate electric wire box, spool embedded.In order to prevent position skew when embedded of various electromechanical built-in pipes and line box, firm with cage bar colligation using the additional spacer bar that has worn during use.
3rd, cast-in-place sleeper model sheetinstallat
As shown in Fig. 2 " one " font or the cast-in-place sleeper of " L " type between two pieces of prefabricated panels, using inner side single side formwork, outboard template is by the use of precast wall panel as exterior sheathing.Use foam strip joint seal, base gap to be tamped with cement mortar between inner side template left and right sides and prefabricated panel, prevent running pulp.Counter screw shuttering adopts full thread M14 screw rods, screw rod one end to be screwed in the sleeve being embedded on the inside of prefabricated panel, and the other end is fastened with nut using conventional chevron card.
20mm gaps between two pieces of precast wall panels autohension rubber bar joint seal.
4th, cast-in-place sleeper concreting
1）The template at concreting position, reinforcing bar, built-in fitting and pipeline etc. are all installed, and are met design requirement on inspection, and are finished hidden, preliminary examination formality.
2）Before sleeper concreting, first poured in bottom to subtract stone 30～50mm of cement mortar with concrete mix identical, then casting concrete again.
3）During concreting in lifts, the layering blanking thickness that layering scale bar controls concrete to be made, placement layer by layer thickness takes 400mm or so.Levels can not be more than the concrete initial set time interval time；Vibrating head shakes and a little uniformly will prevent leakage is shaken.
4）Concrete should be layered and vibrate, and be not more than 30cm per thickness degree.When vibrating vibrating head will " fast insert pull out slowly ", fast inserting is to prevent surface concrete jolt ramming is produced laminated segregation with bottom concrete first.Slowly pull out is in order that concrete can fill up caused cavity when vibrator is extracted out, and can draw the bubble in concrete.
5）Concrete curing
（1）Walls concrete adopts water seasoning, irrigation times to be defined in dampness to ensure concrete wall surface.
（2）Brush sealing compound after the completion of concreting, parcel Polypropylence Sheet are conserved.
（3）Normal concrete curing time must not be less than seven days, and water-proof concrete curing time must not be less than fortnight.
（4）Summer high temperature weather is too fast for preventing young concrete surface moisture to scatter and disappear, conserved after concreting in time, water seasoning number of times is increased according to practical situation and ensures surface wettability, covered with Polypropylence Sheet if necessary tight, and keep in Polypropylence Sheet, having condensate, prevent the appearance of concrete cracks.
（5）After cast-in-place concrete intensity reaches 70%, dismountable temporary support proceeds to next work surface and uses.
5th, prefabricated panel grouting
As shown in figure 3,
1）Grouting operation
（1）The grouting operation time：In prefabricated panel both sides, cast-in-place sleeper and cast-in-situ floor concreting are completed, and the full hall frame of floor carries out grouting operation after removing.
（2）Prefabricated panel grout sleeve is in the milk, from grout sleeve bottom, PVC grout holes are poured into successively, represent when its corresponding top PVC spout hole emerges grouting material and filled in grouting cylinder, spout hole is blocked using cork after filling tight, after continuing to hold pressure 30s, then with cork by grouting hole plugging.
（3）During grouting construction, test cube in the same condition and test specimen need to be made.Grouting material needs indwelling test cube in the same condition, and per one group of test block of every layer of building indwelling, 3 pieces per group, test block specification is 40*40*160mm；Grouting operation often completes 500 reinforcing steel bar connecting sleeve tubes and makees one group of test specimen, and 3 joints of every group of test specimen, during test specimen indwelling, need to operate on dispenser and complete to be in the milk, and rower of going forward side by side is supported 28 days and conserved.As shown in figure figure below：
（4）Blender, agitator, the grouting utensil such as cylinder are cleaned in grouting immediately after finishing, in order to avoid grouting material solidification, cleaning is difficult, and the cylinder that notes being in the milk need to often be irrigated after completing one and be cleaned once, clean and can reuse after finishing.So should at least prepare three grouting cylinders in each teams and groups' grouting operation, wherein one standby.
（5）After the completion of grouting within 4 hours, prefabricated panel must not be vibrated.
6th, precast facade level, vertical joint waterproofing construction
As shown in figure 4, precast facade horizontal joint waterproofing is constructed in the form of one constructional waterproofing adds twice material waterproofing.One material waterproofing inside precast wall body（Hollow rubber waterstop）, before lifting component dropping place, it is pasted on panel tops；Another road material waterproofing（Elastoplast rod and synthesis polymeric seal cream）Topping out, after exterior coating constructed, alien invasion waterproof construction is carried out using hanging basket.
As shown in figure 5, precast facade is vertically sewn on cast-in-place sleeper position, its water proof structure adopts one material waterproofing（PE rods+fluid sealant）Form, constructed using hanging basket.
