A kind of prefabricated prefabricating technique construction technology of superimposed sheet sealing reversed beam of the present invention, including aluminum alloy mould plate, sealing
Beam steel, rear pouring concrete plate and precast concrete, which is characterized in that pouring concrete board bottom portion is equipped with prefabricated mixed after described
Solidifying soil component, the aluminum alloy mould plate and the sealing beam steel are set in the middle part of the rear pouring concrete plate, the aluminium alloy mould
Plate is set on the outside of the sealing beam steel, method includes the following steps:
Step 1, sealing beam steel is prefabricated, increases reserved sealing beam steel, sealing depth of beam in prefabricated board prefabrication process
For 20cm, top controls 2cm concrete cover；
Step 2, sealing beam forms hangs mould, and Screw arbor with nut at both-ends length is 35cm, guarantees that enough length plays the role of to drawing, right
Screw rod is drawn to be welded and fixed with sealing beam steel；
Step 3, template uses aluminium alloy mould, and feature forming demoulds lossless to concrete formation without swollen mould phenomenon
Evil；
Step 4, first pour rear pouring concrete plate pan section, then to plate face initial set before, pour sealing beam concrete, only
Water beam concrete prepares expansive concrete, intensity C25, limited expansion rate using swelling agent " 0.015, swelling agent dosage exists
30KG/m3, no more than 0.5, the slump is controlled in 12-14cm water-cement ratio；
Step 5, it is vibrated using ZV25 vibrating head, mould is hung due to sealing beam forms, so the experienced hand that vibrates is selected,
Beam bottom and plate face are vibrated in place, seamless interfacing, do not allow template of vibrating for a long time, and fast insert is pulled out slowly；
Step 6, remove Screw arbor with nut at both-ends screw thread, under fall aluminum alloy mould plate, after pouring 24 hours, carry out demoulding, and water support
Shield.
The beneficial effects obtained by the present invention are as follows being: the present invention solves the requirement that cannot be guaranteed construction quality in traditional structure,
To guarantee that one-time-concreting and the secondary contact surface that pours clean and carry out dabbing, and vibration compacting in conventional construction method, and it is real
The human-subject test of construction personnel and constructing operation level are difficult to control on border, therefore, are proposed at this stage to prefabricated superimposed sheet sealing
Prefabricating technique construction method of reversed beam is particularly important, and by the preferred of the improvement of construction method and material, can make to construct
The operation is more convenient, mores easily guarantee construction quality, to reach the phenomenon that avoiding the occurrence of leakage generation.
