(11), it is familiar with construction drawing, confirms that concrete foundation elevation, center line, length, each built-in fitting and rebar sizes spacing meet
Design requirement；
(12) arrangement and method for construction, is worked out, construction technology design is carried out；
(13), according to construction drawing and field condition, computation and measurement goes out the consumption of reinforcing bar, concrete, template；
(2), the debris to roofing are cleared up
(3), surveying setting-out
Before construction, setting-out is measured using total powerstation according to construction drawing, and relevant axis position is indicated with red paint,
And repetition measurement is carried out according to drawing axis and construction requirement,
(4), steel bar meter
(41), raw material of reinforcement rebar
(411), the kind of reinforcing bar, rank, specification, quantity have to comply with the regulation of drawing；
(412), every batch of reinforcing bar detected using preceding to its mechanical performance, is detected qualified and is reported rear to a higher authorities for approval and can be used；
(413), after the entering of reinforcing steel bar, nameplate is checked and accepted, stacks and set up respectively by grade, specification, and be sampled censorship；
(414), sampling censorship substandard product removes appearance immediately；
(42) steel bar meter
(421), colligation and welding, the bending of reinforcing bar, the termination of reinforcing bar and joint should all meet design to steel bar meter at the scene
It is required that；
(422), treat after the completion of steel bar meter, the pollutant of rebar surface and iron rust are removed clean；
(5), template processing and installation
(51), template processing
Strict to make template by construction drawing size, requirement, template construct answers physical dimension accurate, and surfacing is bright and clean, and in mould
The inner side brushing paraffin release agent of plate；
(52), template transport and installation
(521), template must assure that template is without damage, pollution-free in transport to roofing procedures；
(522), template is covered when stacking with cloth, and template is protected；
(523), notice that split joint is closely knit during model sheetinstallat, it is ensured that do not reveal slurry；
(6), reinforcing bar colligation and examination
(61), using manually carrying out reinforcing bar carrying；
(62), the colligation of reinforcing bar is performed in strict accordance with regulation, and colligation is firm, smooth vertical and horizontal；
(63), the size of the position of reinforcement installation, spacing, protective layer thickness and reinforcing bar, size are both needed to meet construction drawing regulation；
(64), the overlap joint or weld length of reinforcing bar, then position should meet drawing regulation；
(65) after the completion of reinforcing bar colligation, press《Concrete structure engineering job specfication》GB50666-2011 standards, construction drawing and《Steel
Muscle is welded and control of acceptance》JGJ18-2012 code requirements are inspected for acceptance, and are made a record；
(7), concreting
(71), concreting is used based on truck mounted pumping, and pump rate is 50~60m3/ h, part basis are used and manually poured
Build, pouring simultaneously, vibrating head movement should be moved immediately following concrete duct；
(72) speed of vibrating head insertion, is noted during concreting, the depth in vibrating head insertion concrete is total depth
2/3~3/4, speed is maintained at 12 beats/min, and when keeping vibrating for 4~5 seconds in concrete after insertion, vibrator must not collide mould
Plate, should observe the fast theory inserted and pull out slowly, and when pouring near marking line, pumping line is tried one's best away from pump rate is changed to 50m3/
h；
(73), concrete before pouring in horizontal wall inscription and longitudinal slope bottom reserving hole, it is ensured that roof drainage is not influenceed by basis；
(8), concrete curing, form removal
(81), the surface to strip footing concrete is processed by shot blasting, maintenance treatment is carried out after determining pore-free；
(82), after concreting, in mould outer wrapping puggaree or cooling of watering, and oversite concrete surface immediately, protected
Warm moisture-keeping maintaining；
(83), during conserving, when temperature is higher than 10 DEG C, to retaining material timing water filling ensureing constant moisture state；
(84), during conserving, people is forbidden to be walked on concrete；
(85), non-bearing template must after concrete strength reaches 75% form removal, bearing form is after intensity reaches 90%
Form removal；In demolishing process, it is impossible to which cruelty is removed, form removable should take impact mitigation measure；Form removable is just followed and first torn open
Non-bearing template, after tear the theory of bearing form open.
2. roofing photovoltaic strip footing construction according to claim 1, it is characterised in that setting base in step (3)
Plinth absolute altitude is within 5mm.
3. roofing photovoltaic strip footing construction according to claim 1, it is characterised in that without conjunction in step (413)
Lattice are demonstrate,proved and the reinforcing bar of report of dispatching from the factory forbids admission.
