Description
Technical field
The present invention relates to formwork construction process fields, are exactly a kind of modified cement polyphenyl formwork lattice concrete
Wall pours self-compacting concrete technique.
Background technology
Modified cement polyphenyl mould case lattice type concrete wall is a kind of light set, moisturizing, fire prevention, sound insulation, load-bearing, resists
The multi-functional completely new energy conservation and environmental protection composite building wall construction material in one such as shake, can be used for multilayer residential houses, can use
In load-bearing, non-bearing heat-preserving wall.In the prior art, in a kind of module walls of CN201410001972 self-compacting concrete company
The technical issues of continuous casting method, solution is to complete structure to one-time continuous after the installation for completing construction module wall is in place
The self-compacting concrete of module wall is poured into a mould, the construction method of CN 103993696A wall blocks and wall and wall, is solved
The technical issues of be construction procedure complexity, installing and dismounting inside and outside wall template operation trouble pours complex procedures, inefficiency,
In the prior art, there is no the wall body structure fire safety problems solved truly, that is to say, that these are poured, and wall is practical to be reached
Less than the requirement of fireproof fire endurance, excessive height is generally poured, one-time-concreting is porous, and two-step pouring time interval is long,
In casting process, formwork is easy to loosen, and influences construction efficiency.
Invention content
Pour that wall is practical to be not achieved wanting for fireproof fire endurance the technical problem to be solved by the present invention is to the prior art
It asks, pours self-compacting concrete and pour in process, generally pour excessive height, one-time-concreting is porous, two-step pouring time interval
It is long, lack additional reinforcement part.
In order to solve the above technical problems, the present invention uses following technological means：
A kind of modified cement polyphenyl mould case lattice type concrete wall pours self-compacting concrete technique, and feature includes following step
Suddenly：
1）Pour self-compacting concrete preparatory process：Formwork core bore is clear and coherent, is cleaned out in hole, is installed with that electrical, hot-water heating is pre-buried
Pipeline and built-in fitting, hole, collar tie beam, constructional column, the non-standard formwork installed at door-window opening, need to fix and filling-foam glue is close
Envelope；
2）It pours self-compacting concrete and pours process：First pour cement bonded sand identical with core bore self-compacting concrete strength grade
Slurry；Core bore concreting height should not exceed 0.9m, and two holes of the appropriate to the occasion primary movement of casting concrete every time, and should be along wall
Long connection pours, and intermittent time of two-step pouring must not exceed the concrete initial set time, when concreting should take drill rod into
Pedestrian's work plugs and pounds, and each vertical core bore will plug and pound one by one, until core bore inner concrete holds one's breath bubble, connected core bore inner concrete
Until surface does not decline；
3）Pour self-compacting concrete cleaning sampling process：After concreting, the extra concrete of wall is removed immediately
With the concrete for being attached to surface of wall, when casting concrete, should randomly select concrete sample in its pouring location, as required
Cured under same condition test specimen is made, core bore self-compacting concrete intensity is detected；
4）Pour self-compacting concrete maintenance process：It should be carried out immediately after self-compacting concrete pours in form wall core bore
Maintenance, the visual concrete covering on reply wall top when summer climate is dried carry out water conservation moisture-keeping maintaining, and when winter cold needs
To visual concrete plus heat-preserving anti-freezing layer.
Preferably, the further technical solution of the present invention is：
Described to pour self-compacting concrete preparatory process, when plate formwork concrete structure construction, is mounted on concrete blinding
Inside, poured with structural concrete needs the plate formwork of first well cutting size to be temporarily fixed at cast-in-place concrete mould together
On the inside of plate, the position of formwork is adjusted, the gap of formwork adjacent thereto is made to inject polyurethane foam glue in 5mm or so, gap, Gu
Determine support shuttering after-pouring concrete, form removal after the completion of concrete is raised has completed that formwork is assembled, formwork plate stitch is close
Envelope, temporary support working procedure, steel-bar arrangement protective layer.
Described pours self-compacting concrete preparatory process, and in formwork assembly, formwork is equipped with connecting hole, connection in high spot
Lateral connection bar, lateral connection bar both ends is assigned to be equipped with buckle in hole, opposite install is equipped with vertical reinforcing prop, erects on the outside of formwork
It is equipped with card slot to the side of reinforcing prop, card slot and snaps connection fixation.
The self-compacting concrete that pours pours process, and the cement mortar first poured is 50mm thick.
Described pours self-compacting concrete cleaning sampling process, and the rainy day does not answer casting concrete, just poured the mixed of completion
Solidifying soil will prevent rain drop erosion.
It is described pour self-compacting concrete maintenance process can after self-compacting concrete intensity reaches 5 to 10MPa
Remove temporary support.
Present invention reduces building cost, wall is to reach carrying, energy saving, three body of facing conjunction by disposably constructing
One function, and meet finishing carry requirement with certain intensity.Modified cement polyphenyl mould case lattice type concrete wall is built
Since heat-preserving wall is thin from heavy and light wall, load is substantially cut down in the house made, and foundation's bottom area reduces very much.It constructs in this way
Middle saving lot of materials takes, labour cost, effectively reduces building cost.Modified cement cement polyphenyl formwork although block is larger,
But density is small, and a people can move, and since heat preserving formwork is without building by laying bricks or stones, need to only position and put foamed glue jointing, in construction
Bricklayer masonry mortar is not needed；The labor intensity of worker is reduced, and speed of application can be greatly improved.The globality of structure
Energy is good, construction wall is made all to be connected to become an entirety by netted concrete.This structural system belongs to prefabricated and cast-in-place
Half fabricated construction being combined has prefabricated components and two big advantage of site concrete concurrently, is equipped under plate at building absolute altitude and wall
With the poly- formwork of spill of pitch-row, reinforcing bar passes through body with concrete continuous at floor absolute altitude when job-poured concrete, avoids pre-
Difficult template and the support for not needing Bars In Poured Concrete Slab again of component connection processed, substantially eliminates the weakness of the two, and node connection more has
It ensures, structure is made to have more globality.
