Abstract
The invention discloses early form removal construction method in a kind of clear-water concrete wafer board structure hole, after the completion of the lifting of wafer board unit plate, cast-in-site stripe is left between two pieces of prefabricated wafer boards, cast-in-site stripe is provided with wafer board preformed hole, and its specification and arrangement are consistent with prefabricated board；After prefabricated wafer board lifting is completed, reinforcing bar in colligation preformed groove props up cast-in-place reserved plate hole internal model, then pours cast-in-site stripe concrete, and hole inner template is removed after waiting concrete to have some strength.Easy construction of the present invention, construction quality are good.
Description
Technical field
The present invention relates to early form removal construction method in a kind of clear-water concrete wafer board structure hole.
Background technology
Wafer board refers to Large area reinforced concrete structure floor plates with holes, is constructed as high-level cleaning shop return air,
Required with meeting the clean of general electronic workshop, putting into very big factory building in photoelectricity, electronic chip etc. can be applied.Generally
In the case of wafer board be with FRP（Fiber glass epoxy）Do bucket mould in plate bed die and hole and pour to smash and form, the bucket template after the completion of pouring
Do not removed as bed die and casement.
Some plant designings need to be used clear-water concrete structure, not adopted during construction due to technique or fire-fighting requirements, wafer board
Expoxy glass steel form is used, or uses FRP templates and needs to remove.FRP（Fiber glass epoxy）Template strength is not high, constructs thickness
It is thin, should not form removal be used in turn.Clear-water concrete waffle plate bed die uses multi-plywood template under normal circumstances, and hole internal model is adopted
Use steel form.And when adopt use steel form in hole when, how to accomplish quickly to remove, both constructing operation is convenient, casement improved again
Speed is used in turn, the construction quality, construction speed, cost-effective key of wafer board structure construction is to ensure that.
The content of the invention
It is an object of the invention to provide in the good clear-water concrete wafer board structure hole of a kind of easy construction, construction quality
Early form removal construction method.
The present invention technical solution be：
Early form removal construction method in a kind of clear-water concrete wafer board structure hole, it is characterized in that：Comprise the following steps：
1）After the completion of the lifting of wafer board unit plate, cast-in-site stripe is left between two pieces of prefabricated wafer boards, cast-in-site stripe is provided with China
Husband's plate preformed hole, its specification and arrangement are consistent with prefabricated board；
2）After prefabricated wafer board lifting is completed, reinforcing bar in colligation preformed groove props up cast-in-place reserved plate hole internal model, then poured cast-in-place
Band concrete, hole inner template is removed after waiting concrete to have some strength；
The cast-in-place reserved plate hole internal model is assembled by 3 arc formworks per mold ring by structure steel fabrication, wherein：2
Piece arc length 474mm, 1 arc length 100mm；If the annular transverse flange plate of twice up and down, each piece of arc formwork both sides set vertical method
Pass through vertical flanged plate bolt connection between blue plate edge sealing, three pieces of arc formworks；Upper cover plate external diameter is bigger than aperture by design requirement
30mm, edges of boards Xian is bolted into 45o chamferings, lamina tecti with lower part steel mould tool；Two square tube horizontal strokes are welded on upper cover plate
Beam, for adjusting mould installion absolute altitude and levelness；
3）1 piece of 3 arc formwork outer surface arc length 100mm, wedge shaped shape, its interior annular transverse flange plate arc length
125mm, vertical flanged plate, into 27.09o angles, is easy to die during form removal to be dismantled into drum with arc radial line.
45o chamfering of upper cover plate side Xian into 15*15mm.
Easy construction of the present invention, construction quality are good.Whole mould is divided into three compositions, and wherein width is less a piece of in water
The wedge shaped shape of flat cutting faces, is easy to be tightened with bolt by vertical flanged plate between assembly and disassembly, three dies, just piece is closed
Smoothly；
First tear the smaller die blade of width after the completion of concreting open, because the die blade horizontal profile designs and produces wedgewise block, tear open
After the connecting bolt that vertical flanged plate is released when unloading, by die blade into hole direction gently prize it is i.e. dismountable, when die blade is torn open
After removing, another two panels mould 1 can be easy to remove.
Three bucket wall moulds are fixed on entirety by lamina tecti, both met the requirement of design aperture chamfered edge, three moulds can be fixed again
Tool prevents deformation；
The two horizontal square tubes welded on lamina tecti, can adjust the top mark height and sag of mould, it is possible to pass through the fixed party
Pipe is to prevent die shift.
Whole mould is molded using welding for steel structure, and bolt is assembled, firm to be unlikely to deform, repeat turnover it is up to a hundred it is secondary need not
Trimming；
Mold outer surface is handled by polishing, and concrete surface can reach the perception requirement of clear-water concrete after form removal.
Brief description of the drawings
The invention will be further described with reference to the accompanying drawings and examples.
Fig. 1 is the structural representation of the cast-in-place reserved plate hole internal model of the present invention.
Fig. 2 is Fig. 1 top view.
Fig. 3 is wedge shape die blade structural map.
