Description
Technical field
The invention belongs to architectural engineering construction technique field, specifically a kind of straw concrete exempts from the close rib laminated floor slab of form removal
Construction technology.
Background technology
Current domestic rib floor has a certain degree of application, is characterized in that bottom template need to be installed, is put using filling block
Cavity is formed in concrete structure to reduce deadweight.The research application starting of external rib floor is more early, using light material
The rib floor that filling block is formed, has been widely used in American-European countries.Britain is from the 1970s, in large space
With in-situ ribbed slab is used in the public building compared with large span.Filling block is built including air entrained concrete used by such floor
The materials such as block, sintered clay hollow brick, polystyrene foam block.This rib floor is with prefabricated ribbed component and filling block
Bed die is formed, rib floor is formed after the casting concrete of top.Common in-situ ribbed slab template amount is big, formwork and form removal technique
The shortcomings of complexity, template cost height, long construction period, insulation and defening effect difference.On the other hand, rural areas in our country has largely
Straw refuse, generally produce a large amount of smog in outdoor field burning, burning and cause environmental pollution, be the weight that haze is formed
Want factor.The regenerated resources that stalk raw material category can be recycled, its cost of manufacture is cheap, freight is low;Wall construction letter
It is single, save building cost.
The content of the invention
A kind of straw concrete exempts from the close rib laminated floor slab construction technology of form removal, is based primarily upon a large amount of straw of current agriculture waste
Stalk resource, using the stalk lightweight aggregate concrete prefabricated board such as corn as bed die, overlapping layers assembling reinforcement and pour straw light bone
Expect concrete or normal concrete, form in-situ ribbed slab.After stalk lightweight aggregate concrete prefabricated board supporting removal, construction
Stage turns into a part for in-situ ribbed slab as the stalk lightweight aggregate concrete prefabricated board of bed die, and maize straw lightweight aggregate mixes
Coagulate native prefabricated board and be permanently embedded in flat board and in length and breadth between rib, play a part of insulation, heat-insulated, sound insulation.The present invention solves
Technical scheme used by its technical problem, it is divided into following steps progress:
1. install girt strip bed die.Before bed die installs, levelling unwrapping wire is needed;Bed die uses symmetrical L-shaped light gauge cold-formed steel shape system
Make, design requirement arch camber is pressed at middle part;Bed die bottom is fixed using vertical supporting bar, and spring is provided with the bayonet socket of vertical supporting bar top
Pad, spring pad top use bolt link with bed die, and vertical supporting bar bottom is connected with base or bar of sweeping the floor;In girt strip bed die
With stalk lightweight aggregate concrete prefabricated board lap-joint, the thick foam glue strips of 3~5mm are posted in advance, to prevent being leaked during concreting
Slurry.
2. straw concrete non-dismantling formwork is installed.After girt strip bed die installs completion and reinforced, straw are installed using crane successively
For stalk lightweight aggregate concrete prefabricated board as straw concrete non-dismantling formwork, non-dismantling formwork both ends should be noted that the foam with posting in advance
The closely knit bonding of adhesive tape;Non-dismantling formwork links it is ensured that closely knit between each other.
3. girt strip steel reinforcement cage is installed.Finished product girt strip steel reinforcement cage can use crane lifting in place, rear and non-dismantling formwork steel in place
The upper and lower layer reserved outlet colligation of muscle links, is fixed.
4. colligation superimposed sheet reinforcing bar.The double two-way steel of colligation superimposed sheet on the platform that non-dismantling formwork and girt strip bed die are formed
Muscle;Hydroelectric line and other reserving hole channels are installed simultaneously.
5. fix vibrator.By design requirement, vibrator is fixed on vertical supporting bar, according to the slump of pump concrete
Degree, typically under every girt strip bed die, select to fix a vibrator on the vertical supporting bar of centre and can meet to require;Together
When vibrator wire is smoothed out with the fingers along in wire casing along bed die.Vibrator switch can use button manual, can also use wireless remote
Control is controlled.
6. casting concrete.Poured from big fluidised form pump concrete, it should be noted that equal control material distributing machine, adopt simultaneously
The vibrator for opening and closing relevant position successively with button or remote control mode vibrates, and makes concrete uniformly closely knit;
7. concrete curing.After the completion of concreting, conserved.After the completion of maintenance, girt strip bed die can be removed, supplied
Next construction section is continuing with.
The step 2 straw concrete non-dismantling formwork, plate termination both sides are equipped with non-dismantling formwork preformed groove, and the preformed groove is empty
Gap and girt strip bed die composition cast-in-place concrete girt strip bottom template, the branch after casting concrete as straw concrete non-dismantling formwork
Seat.
The invention has the advantages that combine to form floor bottom by prefabricated stalk lightweight aggregate concrete plate and girt strip bed die
Mould, the bearing after casting concrete as straw concrete non-dismantling formwork, makes straw concrete non-dismantling formwork solid and reliable;Girt strip
Bed die uses the closely knit bonding of foam glue strip, spillage when avoiding vibrated concrete;Pass through vertical supporting bar spring pad and girt strip bed die
It is connected, fixes vibrator on vertical supporting bar, by controlling vibrator to open and close, the vibrations of vibrator are by vertically propping up
Strut passes to girt strip bed die, and girt strip bed die passes to straw concrete non-dismantling formwork, realizes overall floor and uniformly effectively shakes
It is dynamic, vibrate more closely knit;The form of construction work manually vibrated on floor top without worker, impact load is avoided to stalk coagulation
Personnel trample to reinforcing bar on plate during destruction and construction caused by native non-dismantling formwork, and job site is safer;Improve mixed
Coagulate the pouring quality of soil.
Upper reinforcement installation after-pouring concrete forms close rib laminated floor slab, is in tensile region equivalent to major part is eliminated
Normal concrete, institute's remaining part bears vertical load point with tee girder mechanism, and stress is more reasonable, significantly alleviates floor deadweight, section
The materials such as template, reinforcing bar and concrete are saved.Through measuring and calculating, for the cast-in-place concrete flat board generally used, straw light
Aggregate concrete exempts from the close rib laminated floor slab of form removal and conducts oneself with dignity reduction amplitude up to more than 30%.For concrete frame structure building,
Floor deadweight accounts for building from focusing on 30%~40% or so, so floor weight reduction, can make to support and transmitting floor lotus
Beam, post and the basic section of load reduce, and deadweight reduces, and then reduces the deadweight of whole solitary building, realizes the light of building
Type.Building deadweight reduction can make structure vertical load reduce, then under vertical uniform load q each structural elements of building lotus
Effect is carried to reduce.Stalk light aggregate concrete exempt from the close rib laminated floor slab of form removal not only conduct oneself with dignity it is small, and with save mould material, be not required to
Form removal, save the amount of labour, short construction period, there is insulation and sound insulation function.Its material price is cheap simultaneously, work of constructing
Skill is simple.Easily construction technology is torn open with concrete slab combination peace using rib template, model sheetinstallat is removed convenient.
