Abstract

The utility model relates to a beam board combined type big mould used for casting concrete, which is combined and assembled by plywood surface, steel and wood combined type beams and pen purlins. When the beam board combined type big mould is used, the steel and wood combined beams and pen purlins are combined and assembled together by beam clips, the plywood surface is fixed to the steel and wood combined type beams by self-threading screws. The connection and extension between moulds utilize the combination of the pen purlins, the prismatic holes of pen purlin connection boards and flat taper pins. The beam board combined type big mould utilizes and develops the physical and mechanical properties of steel and wood thoroughly and rationally. The utility model has the advantages of simple structure, arbitrary assembly and disassembly, no limit of the number of moulds, easy maintenance, and no insulation treatment in winter construction.

Description

Beam board combined type big shuttering

The utility model belongs to the concrete structure engineering template.

In engineering construction, the used template kind of cast-in-situ concrete construction is a lot, except the gang form of small-sized (fritter), and large-scale in addition (bulk) template, as large steel moulding plate, steel wood combination large form etc.Mainly by steel plate and the moulding of shaped steel rivet welding, because of this template strength height, rigidity is big for large form, and surface finish is good, and piece is big and plate face seam is few, and the number of turnover is many, and long service life so once be subjected to the welcome of unit in charge of construction very much.But it exists weight big mutually with celebrating, props up, takies crane gear often when tearing open and having bad luck, and the time is long; The template typing, versatility is poor, be difficult to adapt to the architectural image that makes rapid progress, and winter construction must be taked the insulation measure; When damaged template, be difficult for repairing,, support its beam and enclose purlin then standing intact, but, have to discard simultaneously because of monoblock template welding typing because of damaged template is plate surface wear or torsional deformation often; In addition, the price of steel product that rises steadily also makes people forbidding.Steel wood combination large form adopts veneer to make the plate face, and directly the beam of gripper shoe face adopts special wooden H-beam or timber truss beam, and the purlin that encloses of brace summer is the U-steel member.This template has large steel moulding plate advantage can't be obtained, so it is rather well received on world's construction market, but have tangible weakness simultaneously again: the beam that adopts timber to make is short application life, the number of turnover is few, particularly apply, by national power and state basic policy are not allowed in the countries and regions of timber resources famine.Also there is the aluminium alloys of employing to make beam in the U.S. and Britain,, on beam, also inlayed wood lath, saved timber, improved the life-span, but expensive aluminum alloy materials is not dared to inquire the people in order to fix with veneer plate face.

The purpose of this utility model is that design a kind ofly can fully, reasonably utilize and bring into play steel, timber physics separately, the beam slab combined type large form of mechanical property, makes its composite assembly arbitrarily,, tear open conveniently, it is easy to upgrade maintenance.

Beam slab combined type large form of the present utility model is by veneer plate face 1, steel clark beam 2 and encloses purlin 3 composite assemblies and form.Plate face 1 can be veneer (comprising bamboo plywood), plank and plastic plate; Steel clark beam 2 is key members of the present utility model, and it is formed by connecting by some bolt by shaped steel and flitch; Have plurality of holes on the shaped steel web of steel clark beam and the edge of a wing, be used for the installation of beam card 4, template operation platform, connection spreading and lifting between the beam; Beam card 4 is made up of the trip 7 of two pairs of symmetries and a connecting rod 8, bolt 9 and nut 10, and the root of bolt is the square-section, the Kong Weiju rectangular opening on the trip that is mated; The purlin 3 that encloses of brace summer adopts section steel manufacture, has some rib types hole on the web at its two ends, is used to enclose the spreading of purlin and the connection between the template; Enclosing purlin junction plate 5 is welded by dividing plate by two square templates, have on it with enclose purlin on identical rib type hole, be inserted into during connection in the middle of the shaped steel that needs two of connection to enclose purlin, beat as going into flat taper pin 6 with hand hammer again, flat taper pin cooperates tight more with rib type hole, slit between its template is just more little, tight more, and the spreading that encloses purlin is also just reliable more.

The course of work of the present utility model is, at first will enclose purlin 3 and steel clark beam 2 is combined with beam card 4, and then with tapping screw plywood facing 1 is fixed on and is combined into a template on the steel clark beam 2, the center to center distance of steel clark beam is generally 〉=and 0.3 meter, the center to center distance of enclosing purlin is 〉=1 meter, two with the connection between the cope match-plate pattern and combination as long as be connected and enclose purlin.The utility model one-tenth flat formwork capable of being combined such as Fig. 6, Angle formwork such as Fig. 7, the flat formwork that has Angle formwork such as Fig. 8 and column template such as Fig. 9, the variation that also can utilize the good flexible of veneer and enclose the purlin shape is made up the arc formwork of various curvature to satisfy the moulding of various concrete structures and architectural image.

Advantage of the present utility model is: fully, reasonably utilizes and brought into play the physical and mechanical property of steel, timber,, upgrade maintenance and be very easy to when as after the veneer wear-out failure of plate face, and beam and enclose purlin and also can continue to use; After if the flitch in the steel clark beam damages, change and get final product, and shaped steel wherein not can with the flitch desynchronize; Member is few, and composite assembly is simple, realizes industrialization, standardized production and commercialized supply easily; The template that can arbitrary combination be assembled into different shape, size do not have " modulus " restriction, both can do the common templates of concrete cast-in-situ, can make creeping formwork again, fly mould, the template in the dedicated templates such as well mould, tunnel mould, can also be as the template of prefabricated units; , form removal is easy, the winter construction template need not done insulation and handle.

The utility model will be further described below in conjunction with drawings and Examples.
