Detailed description of the invention
Below in conjunction with drawings and Examples, the utility model is further illustrated.
As depicted in figs. 1 and 2, bridge precast beam plate plays roof beam structure, and bridge precast beam plate plays roof beam structure, comprises bracing frame 1, supporting traverse 2, lifting gear 3 and suspender 4;
Support frame as described above 1 has lifting spacing 13, and described lifting spacing 13 is made up of to upper end extension the lower ending opening of bracing frame 1; Described lifting gear 3 is arranged on the upper end of bracing frame 1, and between bracing frame 1 and supporting traverse 2; Described suspender 4 is arranged on supporting traverse 2, and described suspender 4 extends in lifting spacing 13.
The Main Function of described lifting gear 3 is lifting supporting traverse 2.When the upper end of support frame as described above 1 refers to that bracing frame 1 is installed, one end is upwards the upper end of bracing frame 1, the one end contacted with installation foundation ground or mounting platform when the lower end of support frame as described above 1 refers to that bracing frame 1 is installed.
Described lifting spacing 13 refers to the lifting space of hoisting prefabricated beam slab 5.As shown in Figure 1, support frame as described above 1 has lifting spacing 13; Described lifting spacing 13 is made up of to upper end extension the lower ending opening of bracing frame 1; Refer to lifting space bracing frame 1 being provided with hoisting prefabricated beam slab 5, and lifting spacing 13 is positioned at the centre of bracing frame 1, and is extended to the upper end of bracing frame 1 by the bottom end opening of bracing frame 1.Such as, bracing frame 1 one-tenth door font or arch-shaped.
In the process of application: the size of carrying out the precast beam 5 lifted first as required, two groups of bridge precast beam plates are set and play roof beam structure, two groups of bridge precast beam plates being played roof beam structure is arranged on basis (ground or mounting platform), and described two groups of bridge precast beam plate spacing risen between roof beam structure are less than the length of precast beam 5.
When lifting precast beam 5, first connected the two ends of precast beam 5 by suspender 4.Then start lifting gear 3, described lifting gear 3 drives supporting traverse 2 to rise.Because suspender 4 is arranged on supporting traverse 2, therefore supporting traverse 2 drives suspender 4 to rise, thus makes precast beam 5 increase along with suspender 4.After precast beam 5 rises to certain altitude, braking lifting gear; Then Beam transportation vehicle is reached the below of precast beam 5, make the compartment of Beam transportation vehicle be positioned at immediately below precast beam 5; Again starting lifting gear 3 makes precast beam 5 decline, and drops on compartment.Then unclamp suspender 4, the Beam transportation vehicle that drives away completes the lifting of precast beam 5.
In sum, the bridge precast beam plate described in this practicality rise roof beam structure due to structure simple, manufacturing cost is lower, therefore, it is possible to reduce construction cost, avoids adopting and carries out beam across pier straddle truck or large-tonnage crane to precast beam and increase cost.Bridge precast beam plate simultaneously described in this practicality plays roof beam structure in the hoisting process realizing precast beam 5, only needs staff to carry out suspender 4 when precast beam 5 is not sling and connects and in hoisting process, start lifting gear 3.But in the process of lifting, needing staffing when adopting large-tonnage crane to lift in conventional method, guarantee precast beam 5 can be lifted on correct position, simultaneously less stable in the process of lifting.Therefore bridge precast beam plate described in the utility model rise roof beam structure application process in drop into manually less, effectively can increase efficiency of construction, reduce construction cost, reduce construction risk, increase construction safety.When adopting large-tonnage crane to lift, crane needs construction plant, and Beam transportation vehicle needs construction plant, and floor space is large simultaneously.But bridge precast beam plate described in the utility model plays roof beam structure when lifting, Beam transportation vehicle directly reaches bridge precast beam plate and rises below roof beam structure, can effectively reduce construction area area.
Described suspender 4 can adopt various ways, and institute's suspender 4 adopts Chain block or wire rope.When suspender adopts Chain block, height and the gradient of precast beam 5 can be regulated when having lifted.When suspender 4 adopts wire rope, cost can be effectively reduced.In order to ensure the stationarity of precast beam 5 in hoisting process.Preferably as depicted in figs. 1 and 2, institute's suspender 4 comprises fining twisted steel 41 and fining twisted steel nut 42; One end of described fining twisted steel 41 is fixed on supporting traverse 2 by fining twisted steel nut 42, and the other end of described fining twisted steel 41 extends in lifting spacing 13.In the process that suspender 4 is connected with precast beam 5, fining twisted steel 41 through the prefabrication and lifting hole that precast beam 5 is arranged, then at fining twisted steel 41 through fining twisted steel nut 42 of screwing in one end of precast beam 5; Thus realize the connection of suspender 4 and precast beam 5.Because fining twisted steel 41 is stiffener, therefore, it is possible to ensure the stability of precast beam 5 in beam process.
The Main Function of described lifting gear 3 is lifting supporting traverses 2; Described lifting gear 3 can adopt various ways, such as mechanic jacks etc., but adopts jack range demands higher, simultaneously not easy to operate.In order to make whole roof beam structure more steady, simultaneously easy and simple to handle in the process of beam, therefore preferably as shown in Figure 1, described lifting gear 3 adopts hydraulic cylinder or pneumatic cylinder.Realize the lifting to supporting traverse 2 by hydraulic cylinder or cylinder, its lifting force is comparatively large and steady.The construction risk in precast beam 5 beam process can be reduced.
In order to be convenient to manufacture bracing frame 1 at construction site; The manufacturing cost of further reduction bracing frame 1.As depicted in figs. 1 and 2, support frame as described above 1 comprises brace summer 11 and two row's support columns 12; Described support column 12 is arranged side by side, and forms lifting spacing 13 between described two row's support columns 12; Described brace summer 11 is arranged on support column 12 top.Bracing frame 1 adopts combinations thereof mode, can utilize discarded steel pipe, steel plate, i beam etc. in construction plant, weld, effectively can utilize waste resource to bracing frame 1, reduces construction cost.
Steady during in order to ensure that bracing frame 1 is installed, further, described support column 12 lower end is provided with installing plate 14.Described installing plate 14 forms support lugn in support column 12 lower end, can make the more stable impact not being vulnerable to out-of-flatness installed surface on installation foundation of support column 12, add bracing frame 1 and install adaptive capacity.
