A kind of construction formwork system
Technical field
The utility model relates to construction formwork technical field, especially relates to a kind of construction formwork system of rapid-assembling/disassembling.
Background technology
Construction formwork is a kind of temporary supporting structure, and it is made by designing requirement, and concrete structure, member position, physical dimension is in accordance with regulations shaped, and when construction, position is relatively fixing, and bears construction formwork deadweight and effect external loads thereon.The working construction formwork of Cast-in-situ Concrete Structural Engineering, is mainly made up of panel, braced structures and connector three parts.Panel is the force bearing plate that directly contacts newly placed concrete; Braced structures is the temporary structure of supporting faceplate, concrete and working load, ensure architectural template structure combine securely, accomplish indeformable, do not destroy; Connector is by panel and braced structures, connects into overall accessory between panel.
In cast-in-situ wall, beam or post construction, traditional construction formwork re-lays the material field fabrication assemblings such as clamping plate on flitch, clamping plate are for construction formwork, its advantage is flexible, can make arbitrarily moulding according to the difference of building structure, but adopt this technique time-consuming, high to operator's technical requirements, flat die plate is made quality and is not easy to ensure, consumes timber resources more.
In order to substitute limited timber resources, also there is at present steel form and aluminum alloy mould plate, this template component and fitting is at produce in factory, assembling at the construction field (site), this template assembly quality is good, and material can all reclaim and reuse, traditional handicraft relatively, saving of work and time, but cost is slightly high, the component and fitting that a whole set of system forms is more, is applicable to typical floor, not general with wooden flat die plate, be not suitable for non-standard layers and building structure variation place.Connection between template and dismounting are all more time-consuming, and template weight is large, and labour intensity is large.
China Patent Publication No. CN103243903A, name is called the patent of " concrete casting device of quick-clamping construction formwork and assembling thereof ", disclose concrete casting device and comprised some construction formworks, adjacent two construction formworks are by the technical scheme together of the grip handle lock stressed joint through waist through hole.The unexposed concrete casting device of this patent uses special inner corner trim mould and external corner mould, if do not use special inner corner trim mould and external corner mould, can strengthen the installation difficulty while construction, is also difficult to planeness and the overall appearance quality of the corner that ensures Cast-in-situ Beam or post.
The disclosed construction formwork of China Patent Publication No. CN103243903A, deviate from concrete surface one side and be provided with strengthening rib strip, between each strengthening rib strip, form groove, when construction, in groove, easily embed concrete, the concrete after sclerosis is difficult for removing, in the time reusing, increase the weight of template, made troubles to construction.
