Abstract
The utility model relates to a big shuttering made of a plywood. The big shuttering made of a plywood is used on the building engineering of a reinforced concrete structure. The big shuttering made of a plywood belongs to the novel equipment of the field of building engineering. The big shuttering made of a plywood adopts a waterproof plywood with proper thickness to substitute the shuttering surface of a steel made shuttering. Thereby, the weight of the big shuttering made of a plywood is reduced, and the rigidity of the big shuttering made of a plywood is reinforced. Due to the fact that the rib structure of the original steel made shuttering is improved by the big shuttering made of a plywood, a thin wall type steel is adopted to be used as a transverse rib, pairwise channel steels with minimum numbers (two strands) are matched to be used as vertical ribs, and the flexibility of the big shuttering made of a plywood is controlled at panel f/L<= 1/500, and the transverse rib and the vertical ribs are f/L<=1/500. Except that the big shuttering made of a plywood has the advantage of tsteel made shuttering, and big shuttering made of a plywood also has the characteristics of light weight, less materials, flexible assembly, strong versatility, and a plurality of turnaround times.
Description
The utility model is a kind of veneer large form, and it is used for the reinforced concrete structure construction work, belongs to the novel device of building engineering field.
Increasing along with highrise building, cast-in-place notes reinforced concrete building template has also grown up.In existing building trade, the application of steel template, to the raising construction engineering quality, efficiency, speed of application all has certain effect.But this template also exists: breadth is little, and spelling is time-consuming, and the construction working amount is big, labor strength height, the shortcomings such as building requirements of large-area metope of incompatibility and bridge letter.Simultaneously the steel of steel template are than great, and it is very heavy with regard to weight to be combined into the large tracts of land template, is difficult to carrying and formwork adjustment verticality, and it is more to add seam, makes the concrete surface that waters rough, and out-of-flatness is not easy to wall decoration.
In order to overcome the above-mentioned shortcoming of steel form, task of the present utility model is a kind of novel template of development, and it also has in light weightly except the advantage with steel template, and assembly unit is simple, and durable durable, breadth is big, and is simple in structure, the characteristics that stiffness is big.
Task of the present utility model is following realization: be developed into a kind of veneer large form, it includes the plate plane system, support system and operating platform.The plate plane system, the plate face of employing waterproof pluwood system is fixed on waterproof pluwood in the steel framework by several dormant bolts, the cross rib of some angle steel that are arranged in parallel at a certain distance or light-gauge steel section is fixed on the waterproof pluwood plate face again.Make perpendicular rib by two foundation butt splices channel-section steel together.On all cross ribs, by certain spacing welding go up parallel to each other and perpendicular to two strands of cross rib should perpendicular rib sidewalls.On these two strands of perpendicular ribs, be respectively equipped with several fraisings (9) for bearing support or operating platform installation usefulness.The framing system of many like this cross ribs and two perpendicular ribs can make whole template amount of deflection be controlled at panel f/L≤1/500, anyhow rib f/L≤1/500.Owing to reduced the unnecessary structure and the parts of former steel form, adopt light-gauge steel section to make rib and make this plywood form not only in light weight simultaneously, and just, intensity is good.The waterproof pluwood of while suitable thickness, the breadth increase to template has played decisive action again, and the rigidity of such veneer plate face also is better than the thick plate face rigidity of 4mm of steel die plate.
This template is in order to adapt to the design feature of highrise building, and design optimization: wide height is by the template of several base types of certain modulus.The plate face specification of these several templates is: 2750 * 2000mm, and 2450 * 2000mm, its cross rib spacing: 250,300 or 350mm, its two gangs of perpendicular rib spacing: 1200mm and with a small amount of benefit plate of high different in width.Use these several template specification can be to the concrete wall formwork of different floor heights, the standard width of a room in an old-style house, depth, wall thickness.This template also can be used in combination it with other template (as small-sized steel frame plywood formwork, veneer circle template and combined steel formwork).
This template, also the bearing support to supporting system improves.Two steel pipes are fixed on the nut of fang bolt in an acute angle, again by this angle on the right perpendicular rib part between two fraisings be that an opposite side has been formed a triangular supporting frame.This bearing support has been saved the complicated unnecessary propping of former steel form, and stiffness and strength and be not less than original structure, two hinges of two steel pipes and two fraising joints formation can be adjusted the verticality of the template of propping up by the nut of fang bolt up and down when leading screw rotates simultaneously, to guarantee the formwork casting quality.
The utility model is the plate face of template owing to having adopted waterproof pluwood, new framing system and new type steel have been adopted again, thereby the rigidity and the intensity of template have been improved, also alleviated template weight simultaneously, the weight that makes every square metre of plywood form between 40～47 kilograms, in light weight more than a times than general steel die.Because the waterproof pluwood of suitable thickness is as template plate face, its rigidity, waterproof, the corrosion-resistant steel template that is better than, therefore the use number of turnover of this plywood form can reach 100～150 times, and construction cost is reduced, and its economic benefit just is better than the steel template.Because the veneer plate face of large format is used for fluid concrete, and casting quality is improved greatly, institute's surface of wall that waters is smooth, need not plaster, but just decorated wall surface.
Accompanying drawing of the present utility model has been described the structural representation of veneer large form.Accompanying drawing 1 is the rib facade structures schematic diagram of veneer large form.Fig. 1 has: plate face (1), steel frame (2), cross rib (3), perpendicular rib (4), dormant bolt (8), through-wall bolt (10).
Accompanying drawing 2 is the facade vertical view of veneer large form.Fig. 2 has: plate face (1), steel frame (2), cross rib (3), perpendicular rib (4).
Accompanying drawing 3 is the assembling schematic diagram of veneer large form.Fig. 3 has: plate face (1), cross rib (3), perpendicular rib (4), bearing support (5), fang bolt (6), operating desk (7), fraising (9), through-wall bolt (10).
An embodiment of the present utility model is as follows:
In certain construction work, the veneer large form that has used a veneer of applying mechanically the deposited film of phenolic resins thermosetting to make, its plate face (1) is of a size of 2750 * 2000mm.The cross rib of this template (3) is light-gauge steel section (returning the type square steel).Shaped steel wall thickness 2.5mm.This template cross rib (3) spacing is 300 and 350mm.Its two strands of perpendicular ribs (4) splice for the paired end of Contraband 63 type channel-section steels and are welded on all cross ribs (3), and the sidewall of channel-section steel and cross rib (3) steel wall welds together.Two fraising (9) spacings that perpendicular rib (4) is gone up for bearing support installation or adjustment usefulness are 1600mm.This bearing support is made the acute angle both sides with φ 28 steel pipes.Fang bolt (6) is T30 * 4-2 type, to adjust the verticality of formwork.Behind the formwork of body of wall two sides, with through-wall bolt (10) T30 * 4-2 type of 3 band pin-and-holes, long 630mm lives two template drawknots, so that bear the lateral pressure (reaching 49 kilograms according to survey) that is gone up cast-in-site by operating desk (7) again.1000 square metres of the shared veneer large forms of this engineering, save the investment reach 40,000 surplus yuan.
