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

Wood large form and preparation method
Technical field
The invention belongs to construction work with template and preparation method, especially relate to 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 normally is welded by steel facing, steel rib etc.; Only be applicable to vertical structure cast-in-situ concrete engineering construction; The large form cost of manufacture is high, transport, deposit and repair resource to have high input, and flat formwork still adopts various ways such as the little template of steel, wooden form when construction; Make the form work engineering construction technology comparatively complicated, generally do not used in more area; Form work engineering generally adopts the multilayer gluing construction timber shutterings to make panel at present; Do rib with the lumps of wood, carry out panel block-by-block assembly unit and itself and lumps of wood rib is solid by the root stickfast during construction at the scene, earlier lumps of wood rib is removed by root during dismounting and again the panel block-by-block is removed with iron nail; The slab joint deviation is big; The construction operation amount is big, and the iron nail consumption is many, and panel and lumps of wood loss are big.
Summary of the invention
The purpose of this invention is to provide a kind of wooden large form that is used for the construction work shear wall and preparation method thereof, make in the processing place, slab joint is tight, and technology is simple, and is easy to operate, safe and reliable, and work efficiency is high, and spillage of material is little, effectively reduces construction cost.
The objective of the invention is to realize like this, a kind of wooden large form is characterized in that the outer side rail large form of this shear wall urceolus is mainly reached drawing hardened system to form by panel, rib, crossbeam, suspension ring; Panel plane is a rectangle, and according to shear wall story height and lateral surface length segmentation sized, panel is that several multilayer gluing construction timber shutterings butt joints are assembled; Rib vertically near back side of panel and with iron nail with panel and rib stickfast, this rib length is greater than panel height and equal extending panel up and down, some ribs are parallel to the panel vertical edge and evenly arrange according to a determining deviation; Each one up and down on crossbeam; It equates with panel length, is parallel to the panel horizontal sides and is located at rib top and bottom part respectively, and with iron nail crossbeam is followed closely at each ribbed back face; Two on suspension ring are located at about head piece 1/4 respectively and stride on the rib at place; These left and right sides suspension ring are all made with bolt, and the top simmering and bending also are welded into ring, and the bottom is passed the rib middle part and about this rib, all establish pressing plate, pad and nut itself and this rib is fastening; Rib and crossbeam are that the lumps of wood is made, and are made up of location split bolt, reinforcing split bolt, sleeve pipe, steel pipe drawing hardened system.
Confirm the outer side rail large form size of this shear wall urceolus according to shear wall exterior wall plane before making; Carry out concrete lateral pressure and calculate the two-way anyhow spacing of spacing and split bolt hole of confirming rib, guarantee that the outer side rail large form of this shear wall urceolus has enough strength and stiffness.Production program: ribs, square wooden beams under the materials and wood panels ingredients - about two ribs in the draw beam height line and draw down two beams rib spacing wire - rings hanging point rib openings and install rings - will crossed beams with nails in accordance with the rib nailed - rings with a crane through the rib rack stand - diagonal rib rack review and correct - the ribs on the bottom edge of the panel to draw - start on along the bottom edge Block panel laying the panels with nails nailed with the ribs - released on the panel reinforcement bolt centerline and right on the front panel of drilling on the bolt holes.The fabricating 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 center displacement 2 ㎜.
The outer side rail large form of shear wall urceolus adopts pillar crane to lift by crane installation in place; Carry out 2 liftings with the steel wire penetrating suspension ring; With location, bottom split bolt lower beam is fixed earlier after hoisted in position, the leveling; Pass each bolt hole with the reinforcing split bolt again this shear wall inner and outer template is reinforced, this split bolt passes a section of shear wall and establishes sleeve pipe so that split bolt is removed, during the outer side rail large form spreading of shear wall urceolus; Per two splicing alignment backs adopt big blade that its both sides of the chest are clamped at interface, reinforce split bolt horizontal steel tube joint according to the standard overlap joint that staggers.The installation quality allowable variation requires: axial location 4 ㎜, cross section inside dimension ± 2 ㎜, floor height verticality 3 ㎜, adjacent forms plate face difference of height 2 ㎜, surface finish<4 ㎜.
Concreting and when reaching side template and removing condition; It is loosening to keep 3~4 location of top layer 3~4 reinforcings split bolt and bottom split bolt earlier; Other reinforcing split bolt and location split bolt are all taken apart and from sleeve pipe, extracted out; After tangling suspension ring with the tower crane wire rope; Again 3~4 of top layers are reinforced 3~4 location of split bolt and bottom split bolt and take extraction apart, the outer side rail large form of this shear wall urceolus is directly lifted by crane install after last layer has been brushed release agent, repeat turnover and use.
A kind of wooden large form proposed by the invention and preparation method thereof is made in the processing place, and slab joint is tight, and technology is simple, and is easy to operate, safe and reliable, and work efficiency is high, and spillage of material is little, effectively reduces construction cost.
Combine accompanying drawing and embodiment that wooden large formwork construction technology proposed by the invention is further described at present.
