Background technology
For a long time, China's building trade mainly uses traditional situ wet operating type, design-build work extensive, on-the-spot
Industry condition is poor, labor intensity is high, spillage of material and building waste amount is big, industrialization degree is low, with country-driven energy-conservation, subtract
The policies such as row, environmental protection are inharmonious.
Tradition cast-in-place concrete structure construction, from set up support for shuttering, assembling reinforcement, to casting concrete, all construction
Scene completes, and situ wet workload is big.Job site generally exist noise disturb residents, dust pollution；Template consumes big, workmen
Many, labor intensity is big, and construction speed is slow, and the construction period is long, big by effect of natural conditions, concrete appearance and Control of Internal Quality
The shortcomings such as difficulty.
Summary of the invention
The present invention is to solve problem of the prior art, it is provided that a kind of prefabricated assembled greening flower pond lifting construction side
Method so that prefabricated assembled greening flower pond installation is convenient, reliable in quality, improves labor productivity, energy-saving and emission-reduction benefit
Significantly.
The method of work that the present invention provides comprises the following steps:
1) prefabricated assembled for finished product greening flower pond is transported at construction carry out quality inspection, after quality inspection is qualified, concentrates stacking；
2) installing suspension centre, using prefabricated assembled greening flower pond as component, utilize suspension centre to be connected with suspender by component, described hangs
Point includes rotating hoisting ring and suspension hook；
3) being connected on tower crane by rope by suspender, utilize tower crane to carry out handling, handling process comprises the following steps, first by tower
Hang slowly lifting, treat that rope stretches, after determining that suspender etc. firmly installs, winch to component, overhead at 1m, hold component, then enter
The at the uniform velocity handling of row component；
4) member bottom section employing steel plate washer carries out absolute altitude control, utilizes level gauge to carry out absolute altitude according to elevation control and accurately copies survey
Work, copies after survey completes, and elevation control steel plate washer forbids touching and mobile.
5) at component is winched to 1 meter from flooring, stabilizing member, slowly guides component to specifying at the 50cm of position, adjusts
Member position, makes the corrugated tube cavity bottom the reserved steel bar head alignment members of appointment location plate face, slowly inserts, and component is preliminary
After in place, crowbar is used to carry out the adjustment of member position；When component is in place, operating personnel should be reminded, it is to avoid industrial accident
Generation；
6) grouting of component corrugated tube connects operation, and first, component uses cement mortar to block, so with the gap of flooring

Connect operation；
7) component and other interstructural gaps, first use polyethylene bar to carry out stuff up a crack, then carry out filleting by cement mortar.
The present invention has the beneficial effects that:
1, prefabricated assembled greening flower pond design standard, production precision height: take full advantage of the advantage that element factory metaplasia is produced, right
Sectional dimension and the arrangement of reinforcement in prefabricated colored pond are designed for uniformity, it is ensured that prefabricated colored pond production standard.In process of production, in advance
The production precision of the system flower sectional dimension in pond, corrugated tube position and the flatness of component, perpendicularity proposes strict requirements, and adopts
Produce prefabricated colored pond with mechanized equipment, be conducive to improving precision, can guarantee that again the quality of architectural engineering.
2, situ wet workload reduces: for comparing more traditional form of construction work, use prefabricated assembled greening flower pond to hang
Dress construction, job site formwork erection area reduces, and reinforcing bar and concrete field engineering amount reduce, and situ wet workload significantly subtracts
Few.
3, labor efficiency is high, the reduction of erection time: cast-in-place structural must carry out reinforcing bar binding at operating surface, template is propped up to compare tradition
If, concreting etc., unified for traditional operating surface operation transferring to, is given birth to by prefabricated assembled greening flower pond lifting construction by factory
Producing, largely reduce the difficulty of construction of operating surface, decrease the working procedure of operating surface, labor efficiency has obtained the biggest
Improving, the duration significantly shortens.
4, structural safety is reliable, and hidden danger is few: the stress characteristic of the straight greening flower pond of root prefabricated uses specific corrugated tube to fill
Slurry connected mode is connected with cast-in-place structural, meets structural bearing capacity and deformation requirements, and prefabricated colored pond component connects reliable, full
The safety of foot structure and durability.
5, energy-saving and emission-reduction remarkable benefit: prefabricated colored pond factorial praluction, decreases construction material loss；Situ wet operation shows
Write and reduce, reduce the generation of building waste；Formwork erection area reduces, and reduces timber usage amount；Reinforcing bar and concrete are existing
Quantities reduces, and reduces the utility requirements at scene, decreases the discharge of the pollutant such as construction noise, flue dust, energy-conservation subtracts
Row's remarkable benefit.
