Specific embodiment
With reference to embodiments and its attached drawing further explains the present invention.
Embodiment 1
Staircase shear wall formwork installation process of the invention:
Template places built-in fitting → installation inner side template in place → installation supports → and is inserted into through-wall bolt and casing etc. → installation just
Position outboard template and support → adjustment template position → fastening through-wall bolt → fixation support → inspection corrects → connect adjacent mould
Plate → do preliminary examination.
It is wide with civil buildings main structure section to be suitable for industry to staircase shear wall formwork installation method of the invention
Staircase shear wall within 200-400mm, high 4200mm, comprising the following steps:
A, unwrapping wire positions: releasing control line according to building axis line and staircase shear wall installs sideline.
B, a side template in stair in place is installed, template uses glued board.
It is the staircase shear wall formwork setting structure schematic diagram of the embodiment of the present invention, figure referring now to Fig. 1 and Fig. 2, Fig. 1
2 be the side view of Fig. 1.As shown, ordering pressure foot by unwrapping wire position, the assembly of template is then carried out, is inserted into installation
Through-wall bolt and casing, the specification and spacing of through-wall bolt should design consistent with template special scheme.
C, installation support: the pull rod or diagonal brace of installation staircase shear wall formwork are required according to stencil design, in staircase
Side template 5 can directly add diagonal brace, and correct its flatness, verticality in installation.The arrangement of diagonal brace should be by template special scheme
Design time is away from the installation such as technical requirements.It is staircase half space 6 between two inner side templates 5.
D, through-wall bolt and casing etc. are inserted into: to guarantee shear wall body construction quality, it is necessary to install cover to reinforcement pad
Block, cushion block are mortar block or plastic clasp.Pad thickness is different because of engineering position difference, cushion block be arranged to it is quincunx, it is through walls
Bolt should be arranged according to the designed spacing of special scheme, and horizontal, smooth vertical and horizontal vertically at line, spacing is uniform.
E, stair outboard template 3 in place and pull rod are installed: needed on the outside of stair with pre-buried nail fixation starting board flitch 4, then into
The assembly of row template is inserted into through-wall bolt and casing in installation, and the specification and spacing of through-wall bolt should be by template special schemes
Design time is away from the installation such as technical requirements.The flitch specification is 40 × 90mm.
F, adjust template position, fastening through-wall bolt: template install check a fastener, bolt, drawing shore whether
Securely, whether template splicing and bottom edge are tight.Preferably close to ground, the intermediate vertical spacing of tie is not more than the road table Zhong Di table
The setting of 500mm equity, upper track tie is from beam bottom 200mm.
G, fixed support, check calibration: check whether the verticality of shear wall formwork, thickness of wall body, protective layer thickness full
Foot design and code requirement, after satisfaction can fixed form support, side fixed edge calibration.The Screw arbor with nut at both-ends cooperates in wall
