Description
Technical field
The present invention relates to immersed tube tunnel construction technique field, particularly relate to a kind of reinforcing cage suspension.
Background technology
Immersed tube tunnel is made up of multiple immersed tube, and immersed tube is formed by reinforcing cage concreting.For large-span steel-reinforced cage, relate generally to the structure such as large-scale immersed tube, case beam, as this kind of structure adopts batch production prefabricating and constructing, will the converting process of reinforcing cage stress system have been related to.Stressed from reinforcing cage moulding bed stress check calculation to template by large span top board.Because reinforcing cage plate flexibility is comparatively large, its suspension needs the Deformation Demands as far as possible adapting to reinforcing cage.As reinforcing cage entirety needs displacement or absolute altitude change, then this suspension is needed to have synchronism and handling.
The domestic batch production due to shorter mention large-scale component is prefabricated at present, therefore temporarily without using example.In abroad immersed tube prefabricated, its usual way is the huge suspension bracket of self-control one, arrange below suspension bracket and much disperse suspension centre, it adopt less suspension centre sling, utilize the rigidity of suspension bracket self to control the synchronism of vertical many suspension centres, this kind of mode seems that construction is comparatively heavy, and operating difficulties, synchronous effect is poor.
Summary of the invention

The object of this invention is to provide a kind of reinforcing cage suspension, with improve reinforcing cage hang synchronism and can be handling.
(2) technical scheme
In order to solve the problems of the technologies described above, the invention provides a kind of reinforcing cage suspension, it comprises pier stud, bridge crane, synchronous control system and jack, described pier stud is two rows be arranged in parallel, described bridge crane is the multi rack be arranged in parallel, and described multi rack bridge crane is laterally located between described two row's pier studs, and often building bridge to hang on is respectively equipped with jack described in multiple stage, described in every platform, the two ends of jack are connected with described bridge crane and reinforcing cage respectively, and described jack is connected with described synchronous control system.
Further, described synchronous control system is multiple stage, and described synchronous control system controls the multiple stage jack on bridge crane described in a frame.
Further, the multiple stage jack on bridge crane described in every frame is put in two parallel arrangements.
Further, the two ends of described bridge crane are respectively equipped with walking mechanism, and described walking mechanism is located on described pier stud.
Further, described jack is feed-through hydraulic jack.
Further, one end of described jack is fixed on described bridge crane, and its other end is connected with the screw-thread steel through described jack; The top of described screw-thread steel adopts nut riveted joint, is provided with suspension ring bottom it; Described suspension ring adopt wire rope to be connected with the stiff skeleton of reinforcing cage.
Further, described synchronous control system is fluid pressure type control system.
(3) beneficial effect
A kind of reinforcing cage suspension provided by the invention, its structure is simple, adopt multi rack bridge crane, often build bridge to hang and multiple stage jack pair reinforcing cage is set carries out suspension operation, and adopt synchronous control system to control accurately the jacking of jack and contractive action, can improve reinforcing cage hang synchronism and can be handling.

Detailed description of the invention
Below in conjunction with drawings and Examples, the specific embodiment of the present invention is described in further detail.Following examples for illustration of the present invention, but are not used for limiting the scope of the invention.
As depicted in figs. 1 and 2, a kind of reinforcing cage suspension of the present invention, it comprises pier stud 1, bridge crane 2, synchronous control system and jack 3, pier stud is two rows be arranged in parallel, the multi rack of bridge crane 2 for be arrangeding in parallel, multi rack bridge crane 2 is laterally located between two row's pier studs 1, and often building bridge to hang on 2 is respectively equipped with multiple stage jack, the two ends of every platform jack are connected with bridge crane 2 and reinforcing cage 5 respectively, and jack 3 is connected with synchronous control system.
Conveniently keep in repair and regulate stress balance, realize single suspension centre adjustable, the synchronous control system of the embodiment of the present invention is set to multiple stage, synchronous control system controls one and to build bridge the multiple stage jack hung on, and often the bridge formation jack hung on 2 can have this synchronous control system to regulate individually or in linkage.Preferably; synchronous control system is fluid pressure type control system; advantage due to hydraulic control system self is convenient to realize automatic working cycle and automatic overload protection; therefore; its be applicable to the present invention for objective for implementation-Large Precast Members; be reinforcing cage in tunnel immersed tube, can guarantee that reinforcing cage hangs the steady of process and safety.
The multiple stage jack hung on of often building bridge is put in two parallel arrangements, increases the stressed suspension centre of reinforcing cage, improves the stress balance of reinforcing cage entirety, avoids reinforcing cage too concentrate due to unbalance stress or stress and deform.
The two ends of bridge crane 2 are respectively equipped with walking mechanism 4, and this walking mechanism is located on pier stud, realize the movement of bridge crane 2 relative to pier stud, and the position of adjustment bridge crane is to regulate the correct position be connected with reinforcing cage.Walking mechanism 4 can be pulley structure, and it comprises slide rail, pulley and hoofing part mechanism, and slide rail is located on pier stud, and the bottom at the two ends of bridge crane is located at by pulley, and hoofing part mechanism drive pulley moves on slide rail, thus achieves the movement of bridge crane.
Jack is feed-through hydraulic jack.One end of jack is fixed on bridge crane, and its other end is connected with the screw-thread steel 7 through this jack 3; The top of screw-thread steel adopts nut riveted joint, is provided with suspension ring bottom it; Suspension ring adopt wire rope 8 to be connected with the stiff skeleton 6 of reinforcing cage 5.Coupled together by the stiff skeleton of screw-thread steel by jack and reinforcing cage, achieve stressed transmission; Because stiff skeleton is supported on the inside of reinforcing cage, be the parts improving reinforcing cage intensity, the bottom of screw-thread steel is connected with the stiff skeleton of reinforcing cage, can reduce the possibility of reinforcing cage distortion further.
A kind of reinforcing cage suspension that technique scheme provides, its structure is simple, adopt multi rack bridge crane, often build bridge to hang and multiple stage jack pair reinforcing cage is set carries out suspension operation, and adopt synchronous control system to control accurately the jacking of jack and contractive action, can improve reinforcing cage hang synchronism and can be handling.Further, synchronous control system controls one and to build bridge the jack hung on, and can realize the independent operation of single suspension centre and the combined operation of multiple suspension centre.
The above is only the preferred embodiment of the present invention; it should be pointed out that for those skilled in the art, under the prerequisite not departing from the technology of the present invention principle; can also make some improvement and replacement, these improve and replace and also should be considered as protection scope of the present invention.
