The application example of the utility model basement barricade single side formwork ruggedized construction and reinforcement means：
Certain engineering is to integrate business, office, the large scale business synthesis of house.Overall floorage is 141889.09
㎡, high building totally 3, highest 123.6m.4 layers of the engineering underground, floor height are respectively -4 layers to -2 layers each 3.6m, -1 layer of 6m.The work
Cheng Yin is adjacent with subway line, and foundation pit west side supporting construction form is lagging pile+reinforced concrete inner support, the deep about 20m of foundation pit,
By subway position basement barricade 10 and lagging pile 16 apart from only 350mm, it can not meet conventional wall form installation, therefore
Single side formwork construction basement barricade can only be used.
Main Construction Technique scheme：
A, single side formwork parameter and main points：
Major parameter table is as follows：
B, construction technique：
Construction technology process：
Lagging pile and retaining wall side reinforcing steel implant → brick mold construction (barricade outboard template) → waterproof and protective layer construction →
Barricade reinforcing bar bind → expire hall frame set up and be connected with earth anchor → barricade model sheetinstallat → horizontal support, skewed horizontal load are constructed → cuts
Knife, which supports construction → anti-floating connection, → earth anchor of lower floor and anti-floating pull rod pre-buried → inspects for acceptance → and concreting → form removal supports
Shield.
Construction method and main points：
1st, 12 reinforcing bars of φ are implanted into by the drilling of spacing rule using deep basal pit lagging pile 16 and retaining wall 23,17 depth of bar planting is big
In 15d, 30 centimeters of leakage length and the waterproof screw 15 of carpenter are effectively welded, and water-stopping pull rod regular arrangement in a row, which is formed, arranges
Anchor structure.After the completion of bar planting 17, blocked with 18 butt joint position of waterproofing unction.
2nd, by mouth line setting-out in brick mold 24 it is accurate after, using 240 thickness MU10 solid bricks, M5 masonry of cement mortar, and right
Gap between brick mold 24 and retaining wall 23 carries out tamping processing, and the lagging pile 16 of prominent brick mold 24 is carried out picking chisel.Using
20 thickness 1：2.5 cement mortar are plastered, as waterproof matrix 25.
3rd, waterproof layer 26 is using II type waterproof rolls (polyester blank) of 4mm thickness SBS-.
4th, barricade reinforcing bar 11 has bound rear, cement lining block and must have been moulded according to 600*600 quincuncial arrangements, cover to reinforcement
Backing strap block also must be provided with place.
5th, full hall frame 6 is set up is set up with reference to socket joint type disk button steel-tube die support construction method, and will be pre-buried before
Good earth anchor steel pipe connecting is in a row, is effectively connected with full hall frame 6, increases full 6 Lateral resisting ability of hall frame.
6th, 10 template 1 of barricade uses 18mm thickness clad can wood plywoods, and outside sets vertical steel pipe secondary beam 2, spacing 200mm.
Girder 3 merges two layers, spacing 700mm for two steel pipes, is fixed using leading screw buckle, connection full-page proof is as schemed ....
7th, the horizon bar of full hall frame also serves as the horizontal support of mounted split pattern, and the step pitch of full hall frame is 1400, can not meet to lead
The reinforcing of beam@700, therefore one of horizon bar of increase among every step is needed, as shown in Figure 1.
Bearing diagonal is arranged with reference to Fig. 1,2, and angle is 30 ° to 45 °, and girder and earth anchor connecting rod are connected to using fastener
On.3.6m floor heights use 3 row's diagonal braces, and 6m floor heights use 4 row's diagonal braces.
8th, it is the stability of increase rectification frame body, bridging should be set on request.Bridging is divided into vertical bridging and water
Flat two kinds of bridging.Vertical bridging, across setting together, is arranged vertically within barricade direction every 4.3.6 meters of floors are in centre position
One of bridging is set；6m floors set twice bridging in middle and tip position.
Form floating when the 9th, to avoid concreting resists, it is necessary to template progress anti-floating connection by what is buried in advance
The welding hook of floating reinforcing bar φ 20 and bottom girder are firm (as shown in Figure 4).Anti-floating reinforcing steel bar sets a row away from wall side 200mm,
Carried out away from 1m pre-buried.
10th, after steel corrosion quantity qualification, whether the jacking of inspection AQL support holds out against, whether bridging by above-mentioned requirements cloth
Put, earth anchor be connected with full hall frame whether reliably, whether firm supporting, measure of anti float perfect etc. for bearing diagonal.After passed examination,
Can casting concrete.
11st, before concreting, it is necessary to tell somebody what one's real intentions are to worker.Concrete is first since the direction away from single formwork barricade
Pour, column beam slab concreting it is complete after, finally pour barricade concrete.This is also for the beam slab coagulation using new building
Soil applies a downward load to full hall frame, increases the Lateral resisting ability of full hall frame.
12nd, concreting is completed, form removal condition form removal to be achieved, checks barricade Forming Quality, and strengthen coagulation
Soil maintenance.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
All any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in the utility model
Protection domain within.
