Abstract
The utility model mainly discloses a rhombic truss supporting jig frame which comprises a jig frame body. Supporting platforms are arranged at the two ends of the jig frame body respectively in an overhang mode. The rhombic truss supporting jig frame guarantees the stability of a rhombic truss and also saves the construction measure cost.
Description
Technical field
The utility model relates to large-scale Rhombic Truss project installation technical field, particularly about a kind of Rhombic Truss support jig.
Background technology
Along with the develop rapidly of Chinese national economy and the continuous enhancing of overall national strength, steel building improves constantly in the ratio of China's building field.The emerging buildings such as large quantities of stadiums, airport, station, theater, large span factory building and bridge of having built of Ru China.And along with the continuous expansion of the scales such as stadiums, airport, must cause the span of steel work constantly to increase, and the increase of span must make truss cross section increase.Steel structure truss generally adopted English truss just can meet the requirement of structure design in the past, and now along with the appearance of more and more large-span structures, steel structure truss adopts Rhombic Truss also more and more general, especially in stadiums.
Although adopt Rhombic Truss to solve Structure Designing Problem in structural steel design, the construction and installation of steel work produced to new problem simultaneously.Because Rhombic Truss cross section is larger, whole height can arrive 10～15m, and in order to meet the demand of architectural image, Rhombic Truss often exists certain angle of inclination, and this just requires to pay particular attention to the stability of Rhombic Truss in installation process.
In installation process, conventional mounting method is one section of Rhombic Truss, to arrange two groups moulding bed is installed now, one group of lower edge that supports Rhombic Truss, one group of middle string that supports shape truss.But must cause like this increase of working measure expense.Therefore how can guarantee the stability of Rhombic Truss in installation process, can guarantee that again the reasonability of working measure expense has become a good problem to study.
Utility model content
The purpose of this utility model is a kind of Rhombic Truss support jig of design, can guarantee the reasonability of working measure expense again, use for reference the equilibrium principle of lever, in conventional lattice, both sides, moulding bed top are installed and add cantilevered structure simultaneously, with the Rhombic Truss of the large-scale inclination of the suspended structural support at two ends.
In order to achieve the above object, technical solution of the present utility model is:
A Rhombic Truss support jig, comprises moulding bed body, the support platform of encorbelmenting respectively at the two ends of moulding bed body.
Two described support platforms, they are highly different.
Described support platform below has support bar and is connected with moulding bed body.
Compared with the prior art the utility model, has the following advantages and good effect:
(1), use for reference the equilibrium principle of lever, in conventional lattice, both sides, moulding bed top are installed and add cantilevered structure simultaneously, truss with the large-scale inclination of the suspended structural support at two ends, make truss in installation process act on both sides to the power of moulding bed simultaneously, thus well balance due to the additional bending moment of encorbelmenting to moulding bed generation itself.
(2), because large-scale Rhombic Truss is used more and more generally in stadiums, for guaranteeing the stable of Rhombic Truss in installation process, in installation process, at least need to support two points.Even using conventional lattice that moulding bed is installed needs at least 2 groups, and the installation moulding bed that band is encorbelmented only needs 1 group, thereby in installation process, can make the lifting number of times of loop wheel machine reduce half.
(3), due to when the layer Steel Structure of stadiums is installed, moulding bed is installed often to be needed to be supported on the concrete grandstand of bottom.The installation moulding bed that uses band to encorbelment can reduce concrete the returning back to top in bottom counts, thereby reduces the cost that bottom returns back to top and reduce the influence area to grandstand.
Accompanying drawing explanation
Fig. 1 is the perspective view of the utility model preferred embodiment;
Fig. 2 is the plane structure schematic diagram of the utility model preferred embodiment.
The specific embodiment
By reference to the accompanying drawings, to the utility model, preferred embodiment is described in further details.
The utility model is to improve on traditional jig structure basis, mainly comprises moulding bed body 1, and the support platform 31,32 of encorbelmenting in moulding bed body 1 left and right sides.
Moulding bed body 1 is generally all the support body being spliced by some vertical rods 11, web member 12, brace 13.Support platform the 31, the 32nd, builds from the top of vertical rod 11.In order to ensure stable, below support platform 31,32, there is support bar 2 and be connected with vertical rod 11, form gusseted structure.
Support platform 31,32 is also that some rod members are spliced, and similar and moulding bed body 1 is generally all the principle by some vertical rods 11, web member 12, brace 13.According to the design feature of Rhombic Truss, wherein support platform 31 height of a side are higher than opposite side support platform 32.When reality is used, higher support platform 32 supports the middle string of Rhombic Truss like this, and lower support platform 31 just supports the lower edge of Rhombic Truss.Can guarantee the stability of Rhombic Truss, save again the expense of working measure.
Above-described embodiment is only for the inventive concept of the present utility model of explaining, but not restriction to the utility model rights protection, allly utilizes this design to carry out the change of unsubstantiality to the utility model, all should fall into protection domain of the present utility model.
