Description
Technical field
The present invention relates to the realm of building construction more particularly to a kind of slab side form post-cast strip erection methods.
Background technique
In order to meet the needs of social development demand at this stage, especially building function and appearance and modeling, engineering construction rule
Mould also gradually expands, also higher and higher to the overall structure quality requirement of engineering works.At this stage, it in post empiricism, adopts
Formwork erection is carried out with wooden model or steel wire, template occurs and is difficult to fix, is easy the problems such as quick-fried mould, spillage, poor molding effect.
Construction technology is obviously unable to do what one wishes, gradually highlights the necessity of construction technology innovation.
Summary of the invention
The purpose of the present invention is to provide a kind of slab side form post-cast strip erection method, the gas formed after being inflated using hose
Column obstructs concrete, has haved the function that side form.
Technical program of the present invention lies in: a kind of slab side form post-cast strip erection method, comprising the following steps:
(1) alter-pouring strips mould plate construction drawing of the design plank thickness in 300mm or more；
(2) preparation of construction: preparation hose, flitch, multi-layer board, inflator pump, air inflation nozzle and hose clamp；
(3) reinforcing bar binds and installs hose: carrying out binding gluten and bottom muscle according to the alter-pouring strips mould plate construction drawing of design, and will be soft
Pipe is mounted in the air column installation cavity bound out between bottom muscle and gluten；
(4) hose is fixed, is inflated: hose being fixed, and completes to block with air inflation nozzle by the both ends of hose by hose clamp, is led to
It overcharges air pump and completes the inflation of hose to form the air column for playing the role of side form；
(5) concreting: the concreting at position other than slab post-cast strip region is completed；
(6) demoulding, hose are deflated, are extracted out；
(7) hose cleaning, recycling.
Further, in the step (3), when slab plate thickness is first laid with lower template in 300 ~ 500mm, and in lower die
Bottom muscle is bound on the upside of plate, and a pair of of wood is provided between bottom muscle and lower template and on the downside of the region for being used to form post-cast strip
Item；Steel bar rack is installed on the muscle of bottom and positioned at the upside of a pair of of batten, and in the setting of the outside of Steel bar rack and Steel bar rack
Between formed air column installation cavity limit steel bar；Hose is mounted on from bottom to top in air column installation cavity；Gluten is bound, and in face
The upside of muscle and be located at air column installation cavity above flitch is respectively set.
Further, the Steel bar rack is arranged by the reinforcing bar of diameter 14mm by 500mm spacing；The limit steel bar
It is arranged by the reinforcing bar that diameter is 10mm by 1000mm spacing.
Further, in the step (3), when in slab have steel plate for sealing water: preset bed course recess portion be laid with waterproof
Coiled material, bed course upside bind bottom muscle, and between waterproof roll and bottom muscle and be located at be used to form under the region of post-cast strip
Side is provided with a pair of of concrete item；One Steel bar rack is set on the muscle of bottom and positioned at the upside of a pair of of concrete item, and in Steel bar rack two sides
The upper end in portion is respectively arranged with the steel plate for sealing water of a cantilever position；The lower end of steel plate for sealing water and a U-shaped steel muscle anchor ear is mutually welded,
And two superimposed hoses are installed respectively in the downside of steel plate for sealing water and U-shaped steel muscle anchor ear；Gluten is bound, and on gluten
And it is located above U-shaped steel muscle anchor ear and is respectively arranged with flitch.
Further, the Steel bar rack is arranged by the reinforcing bar of diameter 14mm by 500mm spacing, the U-shaped steel muscle
Anchor ear is arranged by the U-shaped steel muscle of diameter 10mm by 500mm spacing.
Further, described when seal plate is more than 300mm with the height of lower portion, it heads in the concrete of steel plate for sealing water
Side need to add concrete side Steel bar rack, and the concrete side Steel bar rack is arranged by the reinforcing bar of diameter 10mm by 500mm spacing
It forms.
Further, the hose is containing double-layer polyester fiber reinforcing mat and surface has the hose of PVC coating, institute
The diameter for stating hose is 50mm, 80mm or 100mm；Number three or more of the hose；The blowing pressure of the hose is less than
Or it is equal to 0.6 Mpa.
Further, in the step (6), demoulding is carried out after concrete reaches initial setting strength, hose can not when demoulding
Brute-force pulls out, and after hose need to be deflated, first moves the hose to post-cast strip middle position and extracts out again.
Further, in the step (7), the hose removed after taking out is cleaned up with clear water, is returned after drying
It receives.
Compared with prior art, the invention has the following advantages that hose is inflated after being installed with air pump, inflation
When extrusion packing reinforcing bar of the hose by upper and lower reinforcing bar caused by gap, the air column formed after being inflated using hose carries out concrete
Barrier, has haved the function that side form, the frame structure, frame instead of traditional steel wire, wooden model, suitable for plate thickness 300-500mm
The designs such as frame shear wall structure, shear wall structure have in the engineering construction of post-cast strip.And when disturbing concrete, it is less prone to drum
Phenomena such as packet, spillage, good forming effect are not required to manually to chisel cleaning bulge and spillage, time saving and energy saving, save cost advantages in applying
The raising of working medium amount；The usual comparatively dense of reinforcing bar especially at post-cast strip is met at reinforcing bar, does not need to punch or small with fixation
Batten form is in one line, as long as hose is filled with to gas after passing through between post-cast strip bottom muscle and gluten can complete to pacify
Dress, installation is simple, and it is convenient to construct, and saves the duration；Concreting completion bleeds off gas in hose after reaching initial setting strength, extracts out
Hose completes demoulding, removes and is easy；It can reuse, improve the number of turnover, reduce construction cost.
