Description
Technical field
The present invention relates to demoulding construction methods early in a kind of clear-water concrete wafer board structure hole.
Background technique
Wafer board refers to Large area reinforced concrete structure floor plates with holes, constructs as high-level cleaning shop return air,
It is required with meeting the clean of general electronic workshop, can be applied in the very big workshop of the investments such as photoelectricity, electronic chip.Usually
In the case of wafer board be with FRP(fiber glass epoxy) do plate bed die and hole interior bucket mould is poured and smash, bucket template after the completion of pouring
It is not removed as bed die and casement.
Due to technique or fire-fighting requirements, wafer board need to use clear-water concrete structure for some plant designings, and when construction does not adopt
It needs to remove with expoxy glass steel form, or using FRP template.FRP(fiber glass epoxy) template strength is high, construct thickness
It is thin, should not demoulding be used in turn.Clear-water concrete waffle plate bed die uses multi-plywood template under normal conditions, and hole internal model is adopted
Use steel form.And when adopting in hole with steel form, how to accomplish quickly to remove, not only constructing operation is convenient, but also improves casement
It is used in turn speed, is to ensure that the construction quality, construction speed, the key of save the cost of wafer board structure construction.
Summary of the invention
The purpose of the present invention is to provide in a kind of clear-water concrete wafer board structure hole easy for construction, construction quality is good
Early demoulding construction method.
The technical solution of the invention is as follows:
Early demoulding construction method in a kind of clear-water concrete wafer board structure hole, it is characterized in that: including the following steps:
1) it after the completion of wafer board unit plate lifts, there are cast-in-site stripe between two pieces of prefabricated wafer boards, is set in cast-in-site stripe
There is wafer board preformed hole, specification and arrangement are consistent with prefabricated board；
2) after prefabricated wafer board lifting is completed, reinforcing bar in preformed groove is bound, cast-in-place reserved plate hole internal model is propped up, then pours
Cast-in-site stripe concrete removes hole inner template after waiting concrete to have some strength；
For the cast-in-place reserved plate hole internal model by structure steel fabrication, every mold circumferential direction is assembled by 3 arc formworks,
In: 2 arc length 474mm, 1 arc length 100mm；If upper and lower twice annular transverse flange plate, each piece of arc formwork both sides set perpendicular
To flanged plate edge sealing, it is bolted between three pieces of arc formworks by vertical flanged plate；Upper cover plate outer diameter compares hole by design requirement
The big 30mm of diameter, edges of boards milling are bolted at 45o chamfering, upper cover plate with lower part steel mould tool；Two sides are welded on upper cover plate
Pipe crossbeam, for adjusting mold installed height mark and levelness；
3) 1 piece of 3 arc formwork China and foreign countries surface arc length 100mm, wedge shaped shape, interior annular transverse flange plate arc
Long 125mm, vertical flanged plate and arc radial line are dismantled convenient for piece template when demoulding into drum at 27.09o angle.
Upper cover plate side milling at 15*15mm 45o chamfering.
The present invention is easy for construction, construction quality is good.Entire mold is divided into three pieces composition, and wherein width is lesser a piece of in water
The wedge shaped shape of flat cutting faces is convenient for assembly and disassembly, is tightened by vertical flanged plate with bolt between three sheet molds, just piece is closed
Smoothly；
The smaller die blade of width is first torn open after the completion of concreting, because the die blade horizontal profile designs and produces wedgewise
Block, after when disassembly releases the connection bolt of vertical flanged plate, by die blade, into hole, direction gently agitates i.e. dismountable, works as mold
After piece is removed, another two panels mold can be easy to remove.
Three pieces bucket wall mould is fixed on entirety by lamina tecti, has not only met the requirement of design aperture chamfered edge, but also is capable of fixing three pieces mould
Tool prevents from deforming；
The two horizontal square tubes welded on lamina tecti, the top mark height and sag of adjustable mold, and fixation can be passed through
The square tube is to prevent die shift.
Entire mold is formed using welding for steel structure, and bolt is assembled, firm to be unlikely to deform, and is repeated turnover up to a hundred times and is not necessarily to
Trimming；
Mold outer surface is handled by polishing, and concrete surface can reach the perception requirement of clear-water concrete after demoulding.
Detailed description of the invention
Present invention will be further explained below with reference to the attached drawings and examples.
Fig. 1 is the structural schematic diagram of the cast-in-place reserved plate hole internal model of the present invention.
Fig. 2 is the top view of Fig. 1.
Fig. 3 is wedge shape die blade structural map.
Specific embodiment
Early demoulding construction method in a kind of clear-water concrete wafer board structure hole, including the following steps:
1) it after the completion of wafer board unit plate lifts, there are cast-in-site stripe between two pieces of prefabricated wafer boards, is set in cast-in-site stripe
There is wafer board preformed hole, specification and arrangement are consistent with prefabricated board；
2) after prefabricated wafer board lifting is completed, reinforcing bar in preformed groove is bound, cast-in-place reserved plate hole internal model is propped up, then pours
