Execution step S113, stripping system.After coagulation initial set, stripping system, carries out installing of next section of template, enters cycling.
In side wall template construction process, if run into the structure with inner corner trim, adopt sizing angle mould to connect at side wall inner corner trim place, cornea is connected with core band with stalk shuttering, inner corner trim part supports with monolateral bracing frame after adopting the support of long and short two kind to reinforce again, is connected to become an individual system with stalk, can ensure that interface is tight, not die sinking, not spillage.Specifically in conjunction with shown in Fig. 6, the first bight support bar 401 and the second bight support bar 402 are set at inner corner trim place, the length of the second bight support bar 402 is greater than the length of the first bight support bar 401, the two ends of the first bight support bar 401 and the second bight support bar 402 are connected in the cross rib 103 on panel 101 by core band 105, have formed support and connection in the corner support structure of inner corner trim place both sides panel 101.Then the monolateral bracing frame 30 of support and connection on the first bight support bar 401.
The beneficial effect of the construction method of the monolateral formwork erecting structure of the present invention:
The intensity of monolateral formwork erecting structure is high, adopts embedding and monolateral bracing frame composition support system, makes the intensity of whole supporting and protection structure high, prevents the concrete mould phenomenon that rises.
Lightweight, conveniently moving.The monolateral bracing frame of employing aluminium matter and perpendicular rib, cross rib are aluminium matter, make the gravity of formwork erecting structure global facility light, on-the-spot conveniently moving.
Efficiency of construction is high, adopts modular monolateral bracing frame, can on-site consolidation, and assembled speed is fast, and quality is high, compares conventional punching block and scaffold support efficiency of construction is high.Convenient disassembly, can enter rapidly next section of circulation construction.
Environmental protection, recovery value are high, and aluminum alloy mould plate is novel green structural material, in use, can reduce the generation of noise, after construction, and aluminium recoverable, its recovery value is high.
Applied widely, formwork erecting structure of the present invention is not only applicable to all underground monolateral formworks, can also be used for the top Core Walls Structure construction of super highrise building, increase the application of formwork erecting structure of the present invention, utilize resource effective and reasonablely, improve resource utilization, save cost.
Below embodiment has been described in detail the present invention by reference to the accompanying drawings, and those skilled in the art can make many variations example to the present invention according to the above description.Thereby some details in embodiment should not form limitation of the invention, the present invention by the scope defining using appended claims as protection scope of the present invention.
