Abstract
The invention discloses a big wood formwork. The big wood formwork on the outer side of an outer barrel of a shear wall mainly consists of a panel (1), ribs (3), crossbeams (2), hoisting rings (5) and an oppositely pulling and reinforcing system. By the aid of construction technology for the big wood formwork on the outer side of the outer barrel of the shear wall in building engineering, the big wood formwork is manufactured in a processing field, joints of the panel are close, and the big wood formwork is simple in process, convenient in operation, high in work efficiency and low in loss of materials, is safe and reliable, and effectively reduces construction cost.
Description
Technical field
The invention belongs to form for construction engineering and preparation method, especially relate to the outer side rail large form of a kind of construction work shear wall urceolus and preparation method.
Background technology
Pin-connected panel or monolithic large form that existing building engineering large form is normally welded by steel facing, steel rib etc., be only applicable to the construction of vertical structure cast-in-place concrete, large form cost of manufacture is high, transportation, deposit and repair resource and have high input, and flat formwork still adopts the various ways such as the little template of steel, wooden form when construction, make formwork comparatively complicated, in more regions, generally do not used; Form work engineering generally adopts multilayer gluing construction timber shutterings to make panel at present, with the lumps of wood, do rib, during construction, carry out at the scene panel block-by-block assembled and with iron nail, itself and lumps of wood rib is solid by root stickfast, during dismounting, first lumps of wood rib is removed and panel block-by-block removed again by root, slab joint deviation is large, construction operation amount is large, and iron nail consumption is many, and panel and lumps of wood loss large.
Summary of the invention
The object of this invention is to provide a kind of wooden large form for construction work shear wall and preparation method thereof, in processing place, make, slab joint is tight, and technique is simple, easy to operate, safe and reliable, and work efficiency is high, and spillage of material is little, effectively reduces construction cost.
The object of the present invention is achieved like this, a kind of wooden large form, be characterized in that the outer side rail large form of this shear wall urceolus is mainly by panel, rib, crossbeam, suspension ring and to drawing hardened system to form, panel plane is rectangle, according to shear wall story height and lateral surface length segmentation size, make, panel is that several multilayer gluing construction timber shutterings docking are assembled, rib vertically near back side of panel and with iron nail by panel and rib stickfast, this rib length is greater than panel height and equal extending panel up and down, some ribs are parallel to panel vertical edge and are evenly arranged according to a determining deviation, each up and down, crossbeam, it equates with panel length, be parallel to panel horizontal sides and be located at respectively rib top and bottom part, and with iron nail, crossbeam is followed closely at each ribbed back face, two, suspension ring are located at respectively head piece left and right 1/4 across on the rib of locating, these left and right suspension ring are all made of bolt, top simmering and bending are also welded into ring, pressing plate is all established through rib middle part and in this rib left and right in bottom, pad and nut are fastening by itself and this rib, rib and crossbeam are that the lumps of wood is made, to drawing hardened system by locating split bolt, reinforce split bolt, sleeve pipe, steel pipe forms.
Before making, according to shear wall exterior wall plane, determine the outer side rail large form size of this shear wall urceolus, carry out the spacing of concrete lateral pressure calculative determination rib and split bolt hole two-way spacing anyhow, guarantee that the outer side rail large form of this shear wall urceolus has enough strength and stiffness.Production process is: rib, the blanking of the crossbeam lumps of wood and wooden boards batching---on two roots of left and right, draw crossbeam altitude line and on upper and lower two crossbeams, draw rib spacing line---the rib perforate of suspension ring suspension centre place is also installed suspension ring---crossbeam is used to iron nail and each rib stickfast to the layout line---with tower crane, by suspension ring, rib frame is stood up---rib frame diagonal is checked and is proofreaied and correct---on rib, mark panel hemline---along hemline start to carry out the laying of block-by-block panel and with iron nail by panel and each rib stickfast---on panel, emit reinforcing split bolt center line and on panel, bore split bolt hole.Making quality allowable variation requires: template height ± 3 ㎜, and template length-2 ㎜, template plate face diagonal is poor≤3 ㎜, plate surface evenness 2 ㎜, adjacent panels piece difference of height≤1 ㎜, adjacent panels gap joint≤1 ㎜, split bolt hole the center displacement 2 ㎜.
The outer side rail large form of shear wall urceolus adopts pillar crane to lift by crane installation in place, with steel wire penetrating suspension ring, carry out 2 liftings, hoisted in position, after leveling, first with location, bottom split bolt, lower beam is fixed, with reinforcing split bolt, through each bolt hole, this shear wall inner and outer template is reinforced again, this split bolt is established sleeve pipe through a section of shear wall so that split bolt is removed, during the outer side rail large form spreading of shear wall urceolus, after every two splicing alignment, at interface, adopt large blade that its both sides of the chest are clamped, reinforce split bolt horizontal steel tube joint according to the standard overlap joint that staggers.Installation quality allowable variation requires: axial location 4 ㎜, inside dimension ± 2, cross section ㎜, floor height verticality 3 ㎜, adjacent forms plate face difference of height 2 ㎜, surface finish < 4 ㎜.
Concreting when reaching side template and removing condition, first retain 3～4 the location split bolts in 3～4 reinforcing split bolts of top layer and bottom loosening, other is reinforced to split bolt and locate split bolt and all take apart and extract out from sleeve pipe, with tower crane wire rope, tangle after suspension ring, again 3～4 of top layers are reinforced to 3～4 the location split bolts in split bolt and bottom and taken apart extraction, the outer side rail large form of this shear wall urceolus is directly lifted to after last layer has been brushed release agent and is installed, repeat turnover and use.
A kind of wooden large form proposed by the invention and preparation method thereof, makes in processing place, and slab joint is tight, and technique is simple, easy to operate, safe and reliable, and work efficiency is high, and spillage of material is little, effectively reduces construction cost.
Now in conjunction with the accompanying drawings and embodiments wooden large formwork construction technology proposed by the invention is further described.
