Description
Technical field
The utility model relates to the construction equipment of striding the closure section in a kind of, strides the bed die suspension arrangement of closure section in particularly a kind of.
Background technology
The wide-span case beam cantilever pouring mainly is divided into following three parts: 0# section construction, cantilever pouring are partly constructed and closure section construction, wherein 0# section construction, cantilever pouring is partly constructed and closure section construction in the end bay closure part, all adopt cast-in-place cantilever method usually; The used main equipment of cast-in-place cantilever method is Hanging Basket, through the reach of Hanging Basket, symmetrically to both sides span centre paragraph by paragraph pouring concrete; And apply prestressing force, so cycle operation, but in stride the construction of closure section; Because closure section two beam sections are separated, and can't suspend Hanging Basket in midair, therefore; In stride closure section and need change into usually and adopt the suspension bracket method to stride the construction of closure section in carrying out: the Hanging Basket that promptly earlier former construction is adopted is removed; After removing Hanging Basket, between two beam sections of need closure, suspension bracket is installed again, through suspender belt the bed die of suspension bracket with the closure section is connected again; Install the back through suspender belt with bed die lifting and adjustment bed die absolute altitude, accomplish again and follow-uply stride the construction of closure section part in other.
The main device of suspension bracket method construction is prefabricated brace summer, and brace summer is provided with hoist engine, and hoist engine links to each other with suspender belt, after hoist engine can be promoted to specified altitude assignment with suspender belt, through pin-and-hole preset on the suspender belt, suspender belt and brace summer is fixed.Its mounting method is following: at first need be according to the prefabricated brace summer of closure section span; Then brace summer is lifted between the two closure sections, forms, again through suspension bracket all the other templates of mating formation in order to support the suspension bracket of whole closure section construction; Form bottom die platform; Be the basis again with the bottom die platform, side form and internal mold are installed, until accomplishing whole closure section.
But it has following weak point:
1, the equipment component that adopted of suspension bracket construction such as hoist engine etc., owing in the preorder work progress, do not use, and all be difficult at the construction field (site) seek, need during construction to prepare separately, increased construction cost.
2, with hoist engine as lifting appliance, complex structure, from great has increased the additional load of closed beam section, and hoist engine and suspender belt dismounting are inconvenient.
The utility model content
The technical problem that the utility model will solve is to overcome the above-mentioned deficiency of prior art, and a kind of bed die suspension arrangement of striding the closure section in simple in structure, with low cost is provided.
For solving the problems of the technologies described above, the utility model provides following technical scheme:
Stride the bed die suspension arrangement of closure section in a kind of; Comprise suspender belt and be used to promote the lifting appliance of suspender belt; Said lifting appliance is arranged on the brace summer; Said lifting appliance comprises first jack and second jack, is provided with crossbeam between said first jack and second jack, and said crossbeam is connected with suspender belt is dismantled and assembled.
Through the mode of setting up crossbeam in the middle of first jack and second jack; Form shoulder pole girder, suspender belt passes from crossbeam can realize dismantled and assembled connection, in the work progress of jack before the suspension of closure section bed die use is arranged all; As all including jack at back timber, stiff skeleton etc.; Can obtain jack at the construction field (site), need not to purchase separately, provide cost savings; Simultaneously, adopt jack, compare, have beneficial effect simple in structure, that deadweight is lighter than hoist engine as lifting appliance.
