Abstract
The utility model relates to a large steel suspension box. The large steel suspension box comprises a bottom plate and a side plate which is divided into an inner wall plate and an outer wall plate. A support truss is arranged between the inner wall plate and the outer wall plate and comprises multiple vertical racks arranged at same intervals. In order to change an annular truss arranged between the inner wall plate and the outer wall plate of a conventional large steel suspension box into a vertical-rack-type truss, the vertical racks can be made in advance and inserted between the inner wall plate and the outer wall plate one by one during on-site assembly and then integrally fixed. The large steel suspension box has following beneficial effects: due to differences of stress conditions between a vertical truss structure and the conventional annular truss, bearing capacity of the large steel suspension box is considerably improved, thus leading to direct effects that the distance between the inner wall plate and the outer wall plate is shortened without putting up trusses between the inner wall plate and the outer wall plate and usage amount of steel is greatly reduced to save cost; and the racks are integrally inserted into space between the inner wall plate and the outer wall plate and then fixed during assembly, thus greatly shortening assembly time and making assembling operation more conveniently and rapidly.
Description
Technical field
The utility model relates to bridge construction apparatus field, is specifically related to a kind of novel large steel suspension box.
Background technology
In bridge construction, in recent years, along with the development of national economy, the demand of communications and transportation increases rapidly, and that builds is high-grade large-scale more and more across river bridge over strait.In construction, needing at the scene by enclosing may dash be that construction operation environment is created in follow-up construction, guarantees integrally-built safety and smooth construction in work progress.Large steel suspension cofferdam is usually used among bridge construction, for the large steel suspension box of double-walled construction, is provided with truss for supporting box wall between two layers of walls, makes its unlikely distortion under the effect of hydraulic pressure impaired.Existing large steel suspension box truss is annular truss, sets up layer by layer along the inside and outside wall of large steel suspension box, not only sets up complexity, and force structure is reasonable, is difficult to the inside and outside wall of large steel suspension box to play good supporting role.
Utility model content
The purpose of this utility model is to provide a kind of large steel suspension box, changes the structure of truss between existing double-deck large steel suspension box inside and outside wall, makes its simple installation, saves material.
For achieving the above object, the technical solution of the utility model is: large steel suspension box, comprise base plate and side plate, and described side plate is divided into inside panel and exterior panel, between described inside panel and exterior panel, be provided with sub-truss, described sub-truss comprises the vertical horse that multiple spacing are identical.
While adopting technique scheme, change the multi-layer annular truss between wallboard inside and outside traditional large steel suspension box into vertical chip truss, can make in advance vertical horse, while assembling at the scene, horse vertically be inserted between inside and outside wallboard one by one, then be fixedly connected with integral.The stressing conditions of vertical trussed construction like this and traditional hoop truss structure is different greatly, can greatly improve the supporting capacity of large steel suspension box, direct effect effect is the distance having shortened between inside and outside wallboard, and between wallboard, set up full truss inside and outside noting be used in, reduce widely the use amount of steel, saved spending.In addition, fixing in the space of wallboard inside and outside only prefabricated horse entirety need being inserted when installation, greatly reduce the time that tradition is set up truss, install also more convenient and swift.
Further, in order to improve the supporting capacity of vertical horse, described vertical horse at least comprises two vertical interior mobile jibs and outer mobile jib, between described inside and outside mobile jib, is connected with web member, described interior mobile jib is fixedly connected with inside panel, and described outer mobile jib is fixedly connected with exterior panel.The vertical horse of said structure, can, by the web member between inside and outside mobile jib, support while there is pressure differential and keep the spacing between inside and outside wall between inside and outside wall, plays good support effect.
Further, in order to ensure that truss has good globality, the spacing of vertical horse is unsuitable excessive, and the spacing between described vertical horse is 50～70cm.
Brief description of the drawings
Below in conjunction with the drawings and specific embodiments, the utility model is described in further detail:
Fig. 1 is the plan structure schematic diagram of the utility model large steel suspension box embodiment;
Fig. 2 is the structural representation of vertical horse embodiment in Fig. 1.
Detailed description of the invention
As shown in Figure 1, the utility model large steel suspension box, base plate, inside panel 1 and the exterior panel 2 of large steel suspension box are comprised, between inside panel 1 and exterior panel 2, be welded and fixed sub-truss, sub-truss is made up of the identical vertical horse 3 of multiple spacing, and the spacing between vertical horse 3 remains on 60cm left and right.Wherein each vertical horse 3 has two parallel interior mobile jibs 31 and outer mobile jib 32 at least, between interior mobile jib 31 and outer mobile jib 32, has welded web member, plays the effect of load.
Change the annular truss between wallboard inside and outside traditional large steel suspension box into vertical chip truss, can make in advance vertical horse 3, while assembling at the scene, vertical horse 3 is inserted between inside panel 1 and exterior panel 2 one by one, then be fixedly connected with one.Vertical trussed construction is like this different from the stressing conditions of traditional annular truss, can greatly improve the supporting capacity of large steel suspension box, direct effect effect is the distance having shortened between inside panel 1 and exterior panel 2, has reduced widely the use amount of steel, has saved cost.In addition, when installation, by fixing in the space of horse entirety insertion inside panel 1 and exterior panel 2, greatly reduce the time of installing, installed more convenient and swift.
Above-described is only preferred embodiment of the present utility model; should be understood that; for a person skilled in the art; do not departing under the prerequisite of the utility model structure; can also make some distortion and improvement; these also should be considered as protection domain of the present utility model, and these can not affect effect and practical applicability that the utility model is implemented.
