Abstract

The utility model relates to a mould plate device for casting concrete of a bridge, a tunnel and construction, which is composed of a framework and a panel, wherein, the panel is in a level structure composed of a main plate, and thick overlapping strips which are welded outside a pair of adjacent edges; a concave step which is matched with the thickness of the overlapping strips is arranged on a position corresponding to the position of the framework. Thus, a product of an overlapping edge heighten type mould plate can be produced. The overlapping position in the processes of installation and disassembly or the processes of conveying and keeping prevents flexing, deformation or damage, keeps the casting surface with smooth, finish and beautiful appearance effectively, and satisfies the requirement of the construction quality. The service life of the utility model is over 5 times as long as that of the existing mould plate; the load bearing concrete load-carrying capacity can be enhanced.

Description

The primary steel template

The utility model relates to bridge, tunnel and the building operations a kind of plate device in order to casting concrete.

In bridge, tunnel and building operations, plate device in order to casting concrete, mainly be welded by skeleton and panel, skeleton adopts the standard angle steel to be welded into, panel adopts the monoblock steel plate of 3 millimeters thick to constitute usually, panel staggers certain for the limit, outer that overlaps usefulness at a pair of adjacent edge in skeleton upper edge, be panel stretch out be the boss shape outside a pair of adjacent edge of skeleton, simultaneously another of panel and skeleton constitutes corresponding recessed scalariform to adjacent edge, so that template when splicing mutually with template, is the antithesis accessory of surfacing.The back side in template generally also is provided with handle, has on the periphery of skeleton for fixing and with hole, appropriate location, middle part reinforcing rib is arranged.The first use, the slit is little between template, and the concrete spillage is less, can obtain comparatively smooth, bright and clean mould surface, satisfies the construction quality requirement.The deficiencies in the prior art part mainly is: with certain thickness monoblock steel plate as panel, for intensity, the poor rigidity of overlap joint with place, limit, outer, incompatible with the bulk strength of template, overlapping part is in the process of installing, dismantling or carry, stack, the easiest deflection, distortion, even damage, smooth, the smoothness of mould surface directly influenced, just be difficult to guarantee construction quality several times, cause shorten greatly the application life of template.

The purpose of this utility model is to avoid weak point of the prior art, and provides a kind of construction quality good, the primary steel template product of long service life.

Can take following technical scheme to realize purpose.This primary steel template is welded by skeleton and panel, but panel is by mainboard and is welded in outer, the thicker one side flush-type structure that bonding jumper constituted of a pair of adjacent edge that there are the recessed rank that adapt with bonding jumper thickness the corresponding position of skeleton.Make overlap edge enhanced primary steel template goods.

Under the prerequisite that satisfies the said structure requirement, specific constructive form, length, size, thickness as for the integral body of primary steel template, each funtion part, each zero member, connection between member, fixed form, position relation etc., all can be according to using needs to take the circumstances into consideration to set, they can both realize purpose, guarantee the functional performance and the effect of this primary steel template.

The relative prior art of the technical program has following advantage and effect:

Steel plate with different-thickness constitutes panel, overlap joint is all strengthened with intensity, the rigidity at place, limit, outer, overlapping part is in the process of installing, dismantling or carry, stack, be not easy deflection, distortion or damage, can effectively keep mould surface smooth, bright and clean, attractive in appearance, can satisfy the construction quality requirement, be existing more than 5 times of template the application life of template; Carrying concrete weight bearing power strengthens.

In conjunction with the accompanying drawings, embodiment is described in further detail the content of the technical program.

Fig. 1 is a kind of structural representation of primary steel template;

Fig. 2 is the A-A sectional view of Fig. 1;

Fig. 3 is the B-B sectional view of Fig. 1;

Fig. 4, the 5th, skeleton a kind of schematic diagram of angle steel section.

Among the template of primary steel shown in the accompanying drawing embodiment, it is the mainboard 3 thick δ of panel 2, bonding jumper 4 thick 2 δ, the structure that the dark δ in skeleton 1 recessed rank constitutes.To normally used template, δ gets 3 millimeters and gets final product.Mainboard and the high-frequency welding bonding jumper outside a pair of adjacent edge constitutes work plane jointly and is still smooth panel; When template is spliced mutually with template, surfacing, the skeleton corresponding position that is welded into, be on the used angle steel 5,6 the recessed rank 7 that adapt with bonding jumper thickness to be arranged all, the place, recessed rank of angle steel 5 in order to the bonding jumper welding of panel, can be wide slightly, the recessed rank of angle steel 6 be used for the bonding jumper assembly unit of other template, can be narrow slightly; Weld with such skeleton 1 and panel 2, constitute the primary steel template.During welding, with reference to prior art, panel staggers certain for the limit, outer that overlaps usefulness at a pair of adjacent edge in skeleton upper edge, be panel stretch out be the boss shape outside a pair of adjacent edge of skeleton, simultaneously another of panel and skeleton constitutes corresponding recessed scalariform to adjacent edge, so that during the splicing of template and template, be the antithesis accessory of surfacing.The back side in template can be provided with handle equally, has on the periphery of skeleton for fixing and with hole, appropriate location, middle part reinforcing rib etc. is arranged.

The functional performance of accompanying drawing illustrated embodiment, result of use are good.

Claims

1, a kind of primary steel template, constitute by skeleton and panel welding, it is characterized in that: panel is by mainboard and is welded in outer, the thicker one side flush-type structure that bonding jumper constituted of a pair of adjacent edge that there are the recessed rank that adapt with bonding jumper thickness the corresponding position of skeleton.

2, primary steel template as claimed in claim 1 is characterized in that: it is the thick δ of mainboard of panel, thick 2 δ of bonding jumper, the structure that the dark δ in the recessed rank of skeleton constitutes.
