For a better understanding of the present invention, technical solution of the present invention is done further below with reference to embodiment and attached drawing
Explanation.
A kind of shear wall formwork structure is mainly spliced by several templates 4, and row's template 4 positioned at bottom is set up
On sizing bottom fastener 1, sizing bottom fastener 1 is L-type, if fastener 1 inside in the sizing bottom is uniformly provided with along its length
The first fore shaft plate 12 is done, offers split bolt hole at each first fore shaft plate 12；Sizing bottom fastener 1 includes horizontal cloth
The pressure foot 10 set and the first press strip 11 arranged vertically, first press strip 11 connect l-shaped by nail with pressure foot 10
(i.e. angle steel type structure), the first fore shaft plate 12 are arranged vertically at the inside of the first press strip 11；First press strip 11 and pressure
The triangle stiffener 13 for reinforcing is equipped between sole 10；10 bottom of pressure foot is equipped with foam mat 16.Phase up and down
Fastener 3 in sizing is equipped between adjacent two layers of template 4, fastener 3 includes the second press strip 14 of strip in the sizing, and described the
Two press strips, 14 side is uniformly provided with several second fore shaft plates 15 along its length, is designed at each second fore shaft plate 15 to drawing spiral shell
Keyhole；It is each to draw the template 4 for passing through the fixed shear wall two sides of Screw arbor with nut at both-ends 5 at bolt hole.The vertical edge joint position of the template 4
Equipped with pressing plate 2；Several flitch back cords 6 arranged vertically, the butterfly card 8 of the Screw arbor with nut at both-ends 5 are uniformly provided on the outside of the template 4
Horizontally disposed steel pipe 7 is equipped between flitch back cord 6.
A kind of construction method of shear wall formwork structure, it is characterised in that the following steps are included:
S1, sizing bottom fastener 1 make: the first press strip 11 of 100mm wide and the pressure foot 10 of 50mm wide is respectively cut, it will with iron nail
The first fore shaft of 50mm*100mm plate 12, is then fixed on by the first press strip 11 and the fixed l-shaped of pressure foot 10 by the spacing of 200mm
First press strip, 11 inside, then split bolt hole is drilled out at the first fore shaft plate 12, foam mat 16 is fixed on 10 bottom of pressure foot
Stiffener 13 is finally uniformly fixed between the first press strip 11 and pressure foot 10 by portion；
Fastener 3 makes in S2, sizing: the second press strip 14 of cutting 30mm wide presses the second fore shaft plate 15 of 50mm*100mm
The spacing of 200mm is fixed on 14 side of the second press strip between two parties up and down, then drills out on the centre of the second fore shaft plate 15 to drawing again
Bolt hole；
S3, the reinforcing bar binding for first carrying out shear wall, release template on wall ground floor plate and install control line, exist then along control line
Sponge strip is pasted on floor；
S4, the sizing bottom fastener 1 that shear wall two sides are installed along sponge strip, while wearing Screw arbor with nut at both-ends 5；
S5, the assembly of one layer of template 4 is carried out in shear wall two sides, then pressing plate 2 is followed closely in the vertical edge joint position of template 4, with stent
Plate 4；
Carry out shaping that middle fastener 3 is assembled on S6, template 4 then in step s 5, then in sizing fastener 3 prepared screw-bolt hole
Wear split bolt 5；
S7, repeat step S4, S5 until the template 4 of whole face wall is installed；
S8, the installation for first carrying out flitch back cord 6, then the installation of steel pipe 7 of 5 two sides of split bolt is carried out, with the fixed steel of butterfly card 8
Then pipe is installed nut 9 on split bolt 5 and is reinforced to template 4, completes until the template 4 of whole face wall is reinforced.
Screw arbor with nut at both-ends uses Three-section water stop screw rod if any waterproof requirement according to technique in the above method, and no waterproof requirement is adopted
With plastic bushing and common screw.
After adopting the above method the advantages of:
1, all Screw arbor with nut at both-ends 5 are allowed to pass through from sizing fastener (including fastener 3 in sizing bottom fastener 1 and sizing), without in mould
It punches and reinforces on plate 4, ensure that the integrality of template 4, improve the number of turnover of template 4, improve outside the molding of concrete
Appearance quality.And reduce and repeat perforating after template 4 is had enough to meet the need, block workload, construction efficiency is improved, construction stream is optimized
Journey.
2, setting sizing bottom fastener 1 at the bottom of the shear wall wears Screw arbor with nut at both-ends 5 in the middle part of bottom fastener 1 of being formed, Screw arbor with nut at both-ends 5 from
Ground is closer, prevents bottom from rising mould, rotten.
3, being formed in bottom fastener 1 has pressure foot 10, and pressure foot 10 installs level for the levelling guarantee template 4 in root, simultaneously
The lower foam mat 16 of pressure foot 10, can prevent root spillage and bad root phenomenon to effectively being blocked at local out-of-flatness
Generation；Pressure foot 10, foam mat 16 are set up directly on sizing bottom fastener 1, reduce each installation procedure, and can be with
Recycling.
4, the press strip (including the first press strip 11 with the second press strip 14) of fastener of being formed can be connected using tongue and groove, improve mould
4 stability of plate, the quality of piece, mortar leakage prevention.
5, be formed bottom fastener 1, be equipped with fore shaft plate (the first fore shaft plate 12 and the second fore shaft plate 15) in fastener 3 in sizing, both
Facilitate the assembly of template 4, it is also ensured that flatness, the verticality of template entirety, while preventing typified form from eating mould.
6, it is provided with pressing plate 2 between the vertical piece of template 4, improves piece leakproofness, prevents metope faulting of slab ends, improve smooth
Degree；Fixed form 4 when helping template 4 assembled simultaneously, improves the stability of template 4；
7, sizing fastener is all made of live leftover pieces and is process, and gathers materials on the spot, and stock utilization is high；It is reusable, turnover
Rate is high, meets green construction theory.
Described above is only Application Example of the invention, cannot limit the right model of the present invention with this certainly
It encloses, therefore according to equivalence changes made by scope of the present invention patent, still belongs to protection scope of the present invention.
