Description

A kind of assembled inner-outer wall composite shuttering mortar leakage prevention device and construction method
Technical field
The invention belongs to building field, be specifically related to a kind of assembled inner-outer wall composite shuttering mortar leakage prevention device based on position control device and construction method.
Background technology
Along with the acceleration of Urbanization Construction, armored concrete (structure) building in all parts of the country is also rised sheer from level ground by leaps and bounds, construction material this for concrete, and falsework is the fixing of its indispensability and support means.China experienced by plank sheathing, and steel framework wood (bamboo) assembling plywood template after " with steel generation wood " policy, to present all-steel big shuttering.Plank sheathing needs a large amount of timber, and the yielding destruction in plate face, the number of turnover is few;Steel framework wood (bamboo) assembling plywood template poor rigidity, plate face is yielding and damages.All-steel big shuttering overcomes plank sheathing and steel framework wood (bamboo) assembling plywood template poor rigidity and yielding defect, all-steel big shuttering plate face rigidity is big, wear-resisting, durable, typically can have enough to meet the need use more than 200 times, steel plate face is smooth bright and clean to be unlikely to deform and easily clears up.Using all-steel big shuttering system, after form removal, structure metope reaches clear-water concrete effect, improves the quality of concrete.Entering decoration stage, inner wall surface can save plaster leveling operation, fundamentally stop the common fault in indoor wall gaul, crack, it is to avoid finishing wet trade, has saved cement, the former material of sand consumes and recruitment of plastering.And analyze from the duration, shorten the man-hour of decoration stage and the shortening in man-hour in formwork stage is all beneficial to shorten total lever factor.
Large form is divided into again monoblock type all-steel big shuttering and assembled all-steel big shuttering, and monoblock type all-steel big shuttering is directly by the large form of mould position dimensioned;Assembled all-steel big shuttering is the large form using some pieces of typified forms to assemble.Monoblock type all-steel big shuttering is owing to being customized by body of wall shaping size, thus in upper once engineering for want of versatility and need to revise template size, template improvement expenses is high, and template is easily got rusty, it is not easily repaired after damage, therefore expense produced by monoblock type all-steel big shuttering is bigger.Although and monoblock type all-steel big shuttering concrete surface quality can guarantee that, but in body of wall, door-window opening uses that wooden model frame is prefabricated forms, and is enclosed in large form, its deformation uncontrollable and run mould during concreting, thus door-window opening sectional dimension cannot be ensured.Assembled all-steel big shuttering then be use to meet the master die plate of building module, non-standard punching block plate is auxiliary template, this spelling configuration structure adapts to the demand of engineering, can use on Other Engineering, it is achieved that template, in the recycling of engineering next time, has saved the turnover expense of material.Assembled all-steel big shuttering is because being to be formed by template assembly, then door-window opening is all to block with steel closure plate at open type, and door-window opening, and integral rigidity is good, can observe its deformation during concreting at any time, thorough solution door-window opening is built-in and causes the quality problems such as dimension of opening off normal.
But assembled all-steel big shuttering there is also weak point.Rigidity and the intensity of assembled all-steel big shuttering are big, globality is preferable, it is unlikely to deform, the advantage of hard wear resistant depends on it and uses steel plate as face sheet material, general steel plate thickness is generally 5 ~ 6mm, this certainly will expend steel, steel using amount directly results in greatly it from great, cost is more expensive, and execute man-hour requirement and be equipped with corresponding lifting and Transport Machinery, tower crane elevating capacity in lifting radius be there are certain requirements, construction excessively takies and relies on tower crane, these cause its one-time investment excessive, uneconomical rationally;Assembled all-steel big shuttering is assembled compared with large form by polylith area, therefore its piece is many compared with monoblock type, not only plate face edge joint position is likely to occur spillage problem, spillage phenomenon the most likely occurs with floor contact surface and body of wall contact surface bottom door-window opening mould plate with large form contact surface, large form.For preventing large form spillage in traditional construction technology, use sponge two-sided tape on the contact surface or use mortar caulking joint, preventing the spillage at contact surface;Assembled all-steel big shuttering engineering is in conventional concrete construction external wall construction, the height relying on outer wall template is longer than inside wall formwork, outer wall template bottom sides is close to lower-layer concrete exterior wall surface, stand on bottom template on pylon, utilize tension through-wall bolt and outside-supporting to adjust and fixed outer wall template, cause positioning during model sheetinstallat being forbidden, seam imprecision, cause joint part bottom template to be easily generated faulting of slab ends and spillage, affect appearance and construction quality.For solving the generation of exterior wall floor transition faulting of slab ends phenomenon, at outer wall template patch suitable for reading interpass transition lines steel plate in the traditional handicraft improved.When exterior wall molding, lines steel plate forms groove at wall face, when next time, outer wall template was in place, at the rubber strip that outer wall template end opening patch is more slightly wider than lines plate size, it is embedded in metope groove, strains through-wall bolt, rubber strip is close to concrete surface, playing fixed form and be accurately positioned effect, can avoid the occurrence of the phenomenon such as spillage and faulting of slab ends, after form removal, the groove 1:1 cement mortar of concrete surface is floating.
Assembled all-steel mold plate in traditional handicraft and improve technique there is also all deficiencies.Assembled all-steel big shuttering is also due to it and all uses steel, big from weight, carrying inconvenience, economical unreasonable;Sponge two-sided tape patch seam is used to process at formwork edge joint, template and floor and body of wall contact surface, its sealing is general and material is the softest, during steel form positions, corrects and reinforce, the sliding of template can make sponge two-sided tape come off or shift, whether generation gap at uncontrollable piece and contact surface, therefore the sponge two-sided tape pasted may not have the effect of caulking joint, even results in base contact surface and edge joint position produces the phenomenons such as honeycomb, pitted skin and spillage;Use the traditional handicraft improved no doubt can avoid the faulting of slab ends spillage phenomenon of exterior wall floor, but mounting process is complicated, interpass transition lines steel plate need to be pasted, workman's technology is required higher, and need with the floating groove of mortar after concrete wall surface form removal, this working procedure not only increases cost, and damages concrete appearance effect, reduces concrete formation quality.And outer wall template and inside wall formwork are inconsistent on height dimension, reduce the universal performance of template, improve use cost.
