Description
Technical field
The present invention relates to building concrete mould plate technique field.
Background technology
Tall and big independent cylindrical band is to the enjoyment of people U.S., in order to cater to Popular Aesthetics demand, concrete cylindrical is widely used in building structure, traditional cylinder set shaped steel formwork, wooden form support system cannot meet the requirement of modern architecture construction, because shape is circular, bring the increasing of much inconvenience and difficulty of construction to particularly model sheetinstallat of constructing, have some patent and researchs targetedly at present:
Publication number is that the Chinese patent of CN103184794A discloses a kind of cylinder hoop tuype to spelling wooden form quick template supporting construction method, it by spring column position, place stifled slurry backing plate, the levelling of cylinder mold scope, place steel bar spacer, subsurface work acceptance, installation column-form, merogenesis adjust mold plate verticality, merogenesis is fixed the steps such as card anchor ear is fixed, column-form bracing reinforcement, root stifled slurry, preliminary examination, concreting, cleaning root, form removal and obtained.This invention is by above-mentioned technology, cylinder hoop tuype arranges convex-concave tongue and groove to two semicircle plank sides of spelling wooden form, special construction machinery and equipment is not needed in work progress, fixing hoop and fore shaft screw bolt reinforcing is directly adopted during template splicing, easy accessibility, non-bolt hole, surface, greatly improve Surface Quality of Concrete, the periphery obtained is smooth, there is the resultant effects such as perception is good, cost is low, precision is high, easy construction, be applicable to construction that is industrial and the steel concrete independence cylinder of civilian construction, municipal bridge engineering.But this concrete cylindrical traditional method panel is template to be sawn into lath and to work as side form, tie steel pipe and wooden contract are beaten real fixing, and circular arc degree and verticality difficulty control, and easily cause concrete spillage, surface irregularity, rise mould etc.
Publication number is that the Chinese patent of CN101537660A discloses the installation of a kind of Flexible Fiberglass in Round Column Formwork and dismantle processes, and its operation comprises: reinforcing bar of 1) inspecting for acceptance; 2) cross spacer bars is welded; 3) template and brush release agent is cleared up; 4) post root cleaning; 5) template is in place; 6) closed post mould fixed interface bolt, template limit rib pastes sponge strip, is lifted by post mould to post muscle side, template erect, closed template, clamps limit rib with two angle steel, and aligning bolt hole tightens interface bolt one by one, is closed by post mould; 7) guy wire rope is installed, regulate turnbuckle bar adjustment column mould verticality, from four direction, wire rope is pulled in the crosspoint of post mould main muscle suitable for reading and spacer ferrule respectively, the other end to be connected with pre-buried socketing by turnbuckle bar, by turnbuckle bar adjusting template verticality, suspension column adopts mortar shutoff; 8) concreting; 9) when form removal, form removal, first suspension column mortar is chiseled out, then hawser is unloaded, come loose and remain silent after bolt, with crowbar, template is broken into two with one's hands from interface, template is taken off and removes; 10) template rubbish brushing interleaving agent is cleared up, can not damaging surface corrosion-resisting resin during cleaning template.This invention decreases installation and the dismounting of column-form external support system to a certain extent, reduces the difficulty of construction, has saved cost, but adopt sizing glass fiber reinforced plastic to make post mould, though can accomplish that concrete appearance circle is bent smooth, quality is better, and single operation technical requirements is high, template cleaning maintenance requires high, be not suitable for large diameter cylinder, adopt punching block to do column-form, professional unit need be entrusted to make, its cost is higher, slightly improperly easily affects application life.
Publication number is the constructing structure that the Chinese patent of CN104563496A discloses a kind of cylinder mold, and outside hollow cylinder template, to be wrapped at equal intervals dies plate tap by steel bar tie, hollow cylinder template assigns in the middle of double-pole scaffold vertically; Be laminated to height as required between template mutually, seam crossing is connected by steel bar tie; At cylinder mold 2/3 absolute altitude place, the throwing support structure for guaranteeing pillar verticality and stability is set.This invention tie material is simple, and easy construction is effective to cylindrical reinforcement; Around the double-pole scaffold of cylinder can ensure workman construct in safety; Throwing support steel pipe and short steel pipes form an entirety, effectively can control stability and the concrete verticality of circular columns; This solves a difficult problem for job site circular columns strengthening quality difference, improve construction technology.But for high big column, simple support cannot meet the requirement of its strength and stiffness, and formwork erection system needs to set up large-area lattice scaffold body, props up and tears time-consuming taking a lot of work open.
Publication number is that the Chinese patent of CN103726649A discloses a kind of method making concrete cylindrical template, including bellows, multiple horizontal cuff and multiple wood erects stupefied, the two panels bellows of symmetry is placed by cylindric, a horizontal cuff on middle part cover outside bellows, the multiple wood of placement arranged side by side between horizontal cuff erects stupefied, wood is perpendicular stupefiedly to be wrapped up bellows, and erects stupefied outside at wood and overlap from top to bottom and have multiple horizontal cuff.This invention adopt high density polyethylene (HDPE) as column-form, have from heavy and light, intensity be high, turnover rate is high, inner surface is smooth, good toughness and buying convenient transportation feature; Construction joint is few, planeness is high, the tight not spillage of vertical abutment joint contact, except vertically having except symmetrical twice seam, in the horizontal direction can without seam, and the concrete surface of building out is smooth, color and luster is consistent, circularity is accurate, vertical error is little; Construction is easy to shaping, mounting or dismounting are convenient, work efficiency is high; Do not need complicated external support system, after dismounting, be convenient to maintenance, cleaning.But adopt flitch to do template support, flitch and template are fixed needs and are nailed, and speed of application is slow, and flitch intensity is low, is easily out of shape, and turnover rate is low.The intensity that flitch supports, rigidity are also be not as high as steel pipe support, and for high and big die plate, flitch supporting template system effect not easily ensures.
Therefore, need to formulate one and should ensure cylinder Forming Quality, construction technology simple and quick again, instruct the construction method that column-form supports.
Summary of the invention
