Easy-dismount aluminum alloy pattern plate support system and construction method in narrow movement joint
Technical field
The present invention relates to a kind of construction method of narrow movement joint easy-dismount aluminum alloy pattern plate support system, belong to building construction work
Journey field, suitable for high-layer shear force wall or frame structure movement joint(Width 80mm ~ 200mm subsiding crack, aseismatic joint, expansion joint)
Locate formwork system construction.
Background technology
With the quickening of urbanization process, the build of building becomes increasingly complex, and volume is increasing, to ensure the peace of building
Complete to use, many buildings often set the movement joints such as expansion joint, aseismatic joint, subsiding crack in design.For high-layer shear force wall knot
The building of structure, due to movement joint relatively narrower, poured after deformation joint wall inner side template install it is very difficult, in the past construction when more adopted
Mold method is reinforced with plug flitch in filling cystosepiment or seam, it is easy to causes to stitch interior bulging moding shape, seam inner template can not remove
Phenomena such as clean, cause shear wall faulting of slab ends, the problems such as Forming Quality is poor, size is inconsistent up and down, to make the effect of movement joint beat greatly
Discount, the normal safe handling of building is had a strong impact on, therefore, after deformation joint pouring the control of shear wall quality turns into a great Shi
Work difficult point.Moreover, traditional deformation slit formwork generally use plank sheathing and steel form.The scene processing of plank sheathing needs several wood
Work cooperating, narrow field, the difficulty of construction management is increased, and the plank sheathing number of turnover is few, it is costly.And steel form
Global formation, can be with Reusability, and cast-in-situ stair section size is accurate, but input cost is big, and punching block turnover rate is low, and punching block
Plate is heavier to be inconvenient to lift.
These problems run into for architectural stair in Practical Project, it is necessary to it is high, economic to develop a kind of efficiency of construction
Property good movement joint support system construction method, exactly exploitation forms the present invention in this context, applied to actual change
Preferable economic and social benefits will be produced in shape seam construction.
The content of the invention
Can not it is an object of the invention to drum moding shape, seam inner template in the movement joint for traditional movement joint formwork construction
Phenomena such as clean is removed, causes shear wall faulting of slab ends up and down, the problems such as Forming Quality is poor, size is inconsistent, it is proposed that one kind is narrow
Easy-dismount aluminum alloy pattern plate support system construction method in movement joint, this method is by aluminum alloy pattern plate on the inside of the good movement joint of pre-production and just
Property support manufacturing it is assembled good after, be placed in integral hoisting to movement joint on steel pipe, treat steel reinforcement cage and outside aluminum alloy pattern plate peace
