Embodiment 1：
Tongliao City's filial piety Zhuanghe cultural industry band folk culture shop-Mongolian medicine shop engineering is located at Tongliao City Xincheng District Huolin Gol road
West side, filial piety Zhuanghe's bank landscape belt, boundary of works area include building shown in the drawings such as civil engineering and installation, decorate, electrical, discharge
The full content of the construction drawings design code such as water, HVAC, fire-fighting, ventilation, elevator, light current.This engineering is multilayer public building.
Main body is basement one, and function is open type exhibition room.It is equipped with 5 independent building elevator towers on the ground.2690 squares of overall floorage
Rice, wherein 1818 square metres of basement, 872 square metres of building elevator tower.Building includes 1 layer of basement and 5 stair towers, and building is high
Up to 16 meters of degree, embedded depth of foundation is about 8.5 meters.A height of 7.2 meters of basement floor, base form is raft foundation, sole plate
Thickness is 800, concrete grade C40, seepage-resistant grade P6, and upper structure type is frame-shear-wall structure, beam slab concrete
Grade is C30, floor thickness be basement roof 200,150 ㎜ of upper floor plate.
One, integral construction：
1, technological process is set up
→ → positioning is arranged elongated chock → putting bar of sweeping the floor → and is established by root for foundation bearing capacity experiment for levelling of the land, compacting
Upright bar, pacify immediately with bar fastening of sweeping the floor → installing sweep the floor cross bar and fastened with upright bar or bar of sweeping the floor → first step leger (with it is each
Upright bar fastens) → peace the first step small cross bar → second step leger → the small cross bar of second step → add interim hound (upper end with
Second step leger fastens, dismountable after install twice wall connecting rod) → third and fourth walk leger and small cross bar → wall connecting rod →
Connect upright bar → add bridging → paving scaffold board.
2, erection construction method
(1), according to construction and building plan-position is set up, inside and outside upright bar is measured from metope in building quadrangle first
Distance, and mark.It this time is evenly arranged upright bar position with 50m steel tapes, the spacing of upright bar is not more than 1500mm, and use is red
Paint marks, and then puts chock, and chock must be parallel to metope.
(2), during setting up first floor scaffold, one of bearing diagonal is set along the every frame lattice of surrounding, corner is double
To adding, wait for that the reliable drawknot rear of the wall-connecting piece of the position scaffold and agent structure is dismountable.
(3), double-pole scaffold arranges upright bar in first standing, and rear vertical outer row's upright bar often arranges upright bar and first stands both ends, after drawing logical line,
Stand intermediate upright bar again, the line of inside and outside two upright bar is vertical with metope, when upright bar spreading, first stands outer row, it is rear it is vertical in row.
(4), the first floor and work layer must take hard isolation, completely spread scaffold board between upright bar and metope in scaffold.It applies
Every being closed using Dense mesh screen or other measures between upright bar and building (in 10m) in 3 step frame bodies below work layer.
(5), the guard rail of 0.9m high and the skirting board of 180mm high be must be provided with from second step on the outside of scaffold, pushed up
Row's guard rail sets three guard rails, and height is respectively 1.3m, 0.9m, 0.3m.(door and window at the large span standard width of a room in an old-style house is met in interior upright bar
Hole) guard rail of 0.9m high and the skirt bar of 300mm high need to be added.
(6), it is gone along with sb. to guard him since the scaffolding structure construction period of this engineering only serves, the laying of scaffold board is with work layer
Boundary completely spreads three layers and bottom top layer is completely spread, and the stage to be decorated is laid with layer by layer again.The scaffold board main reinforcement of full laying should be perpendicular to vertical
To horizon bar, docking tiling is completely taped against position, and position of not leaving a blank, there is not allowed that taking the lead, four angles are fixed on support rod with 18# galvanized wires
On, it is desirable that it is smooth to bind secured infall.Scaffold board is accomplished to stand intact, and damaged will replace in time.
(7), scaffold must coordinative construction progress set up, one time adjacent wall-connecting piece or more two is not to be exceeded in scaffolding height
Step.After often having taken a step scaffold, correction step pitch, advance, transfer and the verticality of upright bar should be provided according to specification.
(8), safety net is fixed on the inboard of scaffold outer vertical rod, is used in combination and is hanged up tightly, on the corner not less than 18# galvanized wires
The inside of safety net increases a upright bar, ensures that the straight of safety net, safe Dense mesh screen are increased with construction layer, is higher by construction layer
1m or more.In scaffold negative and positive corner, vertically and horizontally horizon bar necessarily is formed intersecting parallels, refers to Fig. 1.
3, technological process is removed
Safety net → foot guard plate and scaffold board → guard rail → bridging → hound → small cross bar → leger → vertical
Bar.
4, it removes and requires
(1), preparation is removed
1. marking work distinctive emblem, pedestrian is forbidden to enter；
2. checking whether the fastener connection of scaffold, wall-connecting piece, support system etc. meet detailing requiments comprehensively；
3. the sequence of the dismounting in Design of Construction Organization and measure are improved according to inspection result supplement, after authorities ratify
It can implement；
4. carrying out safe demolition technique by Project Technical responsible person to tell somebody what one's real intentions are, and fulfil signature formality；
5. removing the sundries and ground obstacle on scaffold.
(2), dismounting sequence is strictly observed, from top to bottom, that props up afterwards first tears open, is torn open after propping up afterwards, usually first tears railing, foot open
Palm, Crossing brace then tear small cross bar, leger, upright bar etc. open；
(3), it assumes unified command of, echoes up and down, coordination should be informed first pair when unlocking knot related with another people
Side, with fall arrest；
(4), material working tool is transported with pulley rope, must not be thrown out without care.In dismounting, special messenger should be sent to keep an eye on, it must not arbitrarily disorderly
Material is thrown down from high-altitude.All kinds of component and fittings forbid throwing to ground.
(5), removing operation from top to bottom must successively carry out, and forbid to be carried out at the same time up and down；
(6), the stability for removing back frame body is not destroyed, and before wall attaching rod is removed, should add temporary support prevents from deforming,
Wall-connecting piece must successively be removed with scaffold, forbid to tear scaffold open again after first removing wall-connecting piece flood or several layers；Segmentation is removed
Height difference should not exceed two steps；If height difference is more than two steps, wall-connecting piece reinforcing should be added；
(7), it when being torn open when scaffold to the height of last root long upright bar of lower part (about 6.5 meters), first in place should take
If after interim throwing support is reinforced, then removing wall-connecting piece；
(8), when scaffold takes segmentation, discrete faces are removed, reinforcement measure should be taken to the scaffold both ends that do not remove.
