Description
Technical field
The invention belongs to building close rib structure superstructure cast-in-situ concrete shaping instrument field, be specifically related to a kind of separately-loaded formwork that is applied to close rib structure superstructure building.
Background technology
In close rib structure builds practice at present, the plastic form of traditional injection moulding moulding will the brushing release agent or interleaving agent could reduce demoulding difficulty, even like this, after pouring concrete was completed, the plastic form of integral demounting needed just to facilitate form removal in about 25 days, and was wrapped up by concrete due to five, whole form removal difficulty is large, speed is slow, approximately tears for each person every day 30-40 open, is dismounted badly the loss that causes also up to more than 5%.Therefore, conventional plastic formwork lease quantity is many, turnover is slow, breakage rate is high, labour cost is crossed high drawback, causes consumable material too much, uneconomical not environmental protection.Although recent year has been released disposable magnesite building form, but the halogen ion concentration of its material own surpasses the GB requirement, and also there is larger difference in the coefficient of expansion, add itself and belong to precast construction, its shrinkage factor is different from concrete, time has been grown, and particularly under the conditions such as earthquake or fire, has sizable potential safety hazard.And due to disposable use, also greatly increased the social environment cost.Therefore, obtaining formwork more easily is also the problem that China's safety standards for buildings and international standard integrate with and must solve in process.
Summary of the invention
The purpose of this invention is to provide a kind of formwork that is applied to close rib structure superstructure building, namely a kind of combined type that can early tear quick detach open has enough to meet the need formwork, thereby makes up the deficiencies in the prior art.
Separately-loaded formwork of the present invention includes the lamina tecti that is used to form upper surface and the side plate that is used to form four side surfaces, carry out dismountable connection by convergence piece between two adjacent side plates, and lamina tecti is arranged on convergence piece with removably also.
Described convergence piece includes for two sides that side plate is installed, and the angle of two sides is 30-110 °;
Described convergence piece also includes for the connecting portion that connects side, and connecting portion is circular arc.
Have the side plate installing hole for fixed side on described side, the top of connecting portion has the lamina tecti installing hole for the fixed roof plate.
Separately-loaded formwork of the present invention also includes for the stiffening girder that plays stabilization.
Side plate of the present invention is isosceles trapezoid, with the angle of horizontal plane be the 30-90 degree
The width of lamina tecti of the present invention and side plate and/or height are regulated with connection strap.
Above-mentioned lamina tecti and side plate are fixed on convergence piece by the screw bolt and nut structure, or are arranged on connector by the screw rotation mode.
The material of formwork of the present invention can be plastic plate, aluminium-plastic panel, construction formwork, iron plate etc.
Formwork of the present invention is simple in structure, compact, can accomplish each root arc prism connector is connected close and firm with crossbeam, sidewall, and can repeatedly make up dismounting and use, and easy for installation.Compare with existing formwork, the present invention can reduce hiring cost effectively, increases the formwork turnover frequency, reduce the formwork loss, can guarantee again aesthetics and the intensity of concrete cast-in-situ face, can accelerate the duration simultaneously, can obviously reduce the integrated cost of building close rib structure superstructure.Device of the present invention can be applicable in the floor construction in the fields such as underground garage, underground civil defense engineering, market, factory building, highrise building.
