Description
Technical field
The invention belongs to building engineering technical field more particularly to a kind of deformation joint wall formwork construction methods.
Background technique
It is very universal to super long building setting deformation joint at present, and some buildings are provided with two-sided shearing in deformation joint
Wall, and since the spacing of deformation joint is too small, it is unable to satisfy the normal formwork operating space of operating personnel.As many residential buildings two are single
Concrete gable is provided between member, and the spacing designed is 200mm~300mm, is more than double walls of 2m, Jiu Huicun for wall length
Reinforced in wall formwork it is difficult, when concreting easily occur rising mould, quick-fried mould the phenomenon that, such case is engineers and technicians face
The problem faced.
CN201710142170.7 " a kind of deformation joint formwork construction method ", using common screw, wall outside
The main joist of template is φ 25mm bi-steel, and secondary joist is the flitch of 40 × 90mm, template use >=12mm thickness glued board, double steel
Muscle is welded and fixed with mountain type card, welded nut on the type card of mountain, then reinforcing bar is fixed in template using steel nail and forms whole, installation
When outboard template is first installed, then be screwed into the nut welded on screw rod to outboard template, then seal inner side template；In first being torn open when dismounting
Side template, then remove entire screw rod, last overall pulling down outboard template and primary and secondary skeletal frame exist in the work progress and ask as follows
Mountain type card: 1, need to be welded on reinforcing bar by topic, and need the welded nut again on the type card of mountain, and welding workload is larger, 2, coagulation
Side template is easy to appear deviation within the walls when soil pours, and 3, do not have any support, deformation slit formwork assembling inside deformation slit formwork
When be easy to appear deviation, influence construction quality, 4, screw rod need whole dismounting, remove heavy workload.
Summary of the invention
