Description
Technical field
The invention belongs to construction engineering technical field, and in particular to a kind of avoid-dismantle outer wall of basement flange single side formwork dress
Put and construction method.
Background technology
During basement structure construction, due to place limitation, supporting construction is closer to the distance apart from outer wall of basement, such as
There is no operating space using two-sided formwork, be now accomplished by carrying out single side formwork.Outer wall of basement is in the design process, it is contemplated that
Working procedure, can reserve horizontal construction joint (i.e. underplate concrete face based on flange, code requirement height on outer wall of basement
On turn over >=300mm), traditional construction way uses the anti-formwork way pushed up of plank sheathing+flitch+steel pipe for flange, due to one side
Formwork add pour section width (under original place outdoor wall thickness+outer wall of basement to support pile distance), traditional applies
Flange height is often according to the modulus (being highly 900mm) of one block of plank sheathing come what is formulated in work method, in order to avoid cutting
Template, is caused to waste, but due to excessive height, not easy to operate, easy swollen mould, rat after flange shaping is directly affected down
The construction quality of procedure horizontal construction joint above large area wall single side formwork, causes outer wall of basement concreting to be molded
Construction joint joint out-of-flatness afterwards, wall body vertical degree is unsatisfactory for requiring.
The content of the invention
It is an object of the invention to provide a kind of avoid-dismantle outer wall of basement flange single side formwork device, the device is using mixed
Solidifying soil is prefabricated to be formed, surfacing, and has enough rigidity, and surface will not be deformed, and the device is equal to outer wall of basement steel
Tendon protective layer, can effectively control outer wall of basement flange perpendicularity, it is ensured that next procedure quality.
, should it is another object of the present invention to provide a kind of avoid-dismantle outer wall of basement flange single side formwork construction method
Construction method simple and fast, can effectively ensure that the perpendicularity and flatness after the assembly of precast concrete thin plate, and pouring
In Concrete, the precast concrete thin plate after the completion of assembly is influenceed by concrete lateral pressure, and stitching portion will not become
Shape.
To achieve these goals, the present invention uses following technical scheme：
A kind of avoid-dismantle outer wall of basement flange single side formwork device, including precast concrete flat board, precast concrete are U-shaped
