Description

Technical Field

[0001] This utility model relates to the field of equipment for hanging basket construction, and in particular to a trackless triangular hanging basket flange template walking device. Background Technology

[0002] When constructing a continuous beam (rigid frame) bridge, a hanging formwork is typically used for cantilever casting. During cantilever casting, the hanging formwork is first assembled on the completed No. 0 segment, and then concrete is poured on the hanging formwork system 4. During construction, the hanging formwork moves forward with the traveling system. When the closure at the mid-span is completed, the hanging formwork is removed, and the cantilever casting is completed.

[0003] In existing technologies, the movement of the hanging basket is usually achieved by using hydraulic jacks to push the main longitudinal beam. The flange formwork is typically moved by using sliding beams, sliding beam trolleys, and hanging rods. The front end of the sliding beam is suspended from the front upper crossbeam by the hanging rods, and the rear end is fixed to the poured segment by the sliding beam trolley. The movement of the front upper crossbeam causes the front hanging rod to tilt, generating a horizontal force that drives the flange formwork to move. During the movement, the front hanging rod often tilts and bends, or the sliding beam trolley rolls poorly, causing the formwork to jam and leading to the overturning of the hanging basket flange formwork, resulting in low safety. Utility Model Content

[0004] The purpose of this utility model is to provide a trackless triangular hanging basket flange template walking device to solve the problem that existing flange templates are prone to overturning during the walking process.

[0005] To solve the above-mentioned technical problems, the present invention adopts the following technical solution:

[0006] A trackless triangular hanging basket flange formwork traveling device includes a prismatic truss, a lower crossbeam suspension structure, a sliding beam suspension support structure, a formwork support frame, and a formwork structure. The bottom surface of the rear part of the prismatic truss is connected to the top surface of the already cast segment. The front end and middle part of the prismatic truss are respectively provided with a front upper crossbeam and a rear upper crossbeam. The lower crossbeam suspension structure includes a front lower crossbeam suspension structure and a rear lower crossbeam suspension structure. The front upper crossbeam of the prismatic truss is connected to a front lower crossbeam through the front lower crossbeam suspension structure, and the rear upper crossbeam of the prismatic truss is connected to a rear lower crossbeam through the rear lower crossbeam suspension structure. The sliding beam suspension support structure includes a sliding beam front suspension support structure and a sliding beam rear suspension support structure. The structure comprises a front suspension support structure and a rear suspension support structure connected to the front upper crossbeam and the cast-in-place segment, respectively. The bottom surface of the formwork support frame is connected to the top of the slide beam passing through the front and rear suspension support structures. The formwork structure is set on the inner surface of the formwork support frame. The upper part of the rear lower crossbeam suspension structure is provided with a formwork support crossbeam. The formwork support crossbeam is horizontally set at the bottom of the slide beam with its direction perpendicular to the direction of the slide beam. The bottom of the back rib of the formwork structure is provided with a corbel structure, which is fixedly connected to the front lower crossbeam and the rear lower crossbeam.

[0007] In this solution, a rear lower crossbeam suspension structure is set on the rear upper crossbeam, and a template support crossbeam is set on the upper part of the rear lower crossbeam suspension structure. This forms an L-shaped hook structure on the upper part of the rear lower crossbeam suspension structure. During construction, the flange template is lowered and placed on the L-shaped hook structure, the front lower crossbeam, and the rear lower crossbeam. When moving, the movement of the template support crossbeam drives the synchronous movement of the sliding beam and the flange template structure. This solves the technical problem that the front sliding beam hanger is prone to tilting and bending when the flange template structure moves, which may cause the hanging basket to overturn.

[0008] As a further preferred embodiment of this utility model, the rear lower crossbeam suspension structure includes an inverted "T"-shaped support structure, a suspension screw, and a suspension belt arranged sequentially from top to bottom, with one end of the bottom surface of the template support longitudinal beam installed on the support surface at the bottom of the inverted "T"-shaped support structure.

[0009] The support surface of the inverted "T" shaped support structure is used to support the template support beam, and such a support structure is stable.

[0010] As a further preferred embodiment of this utility model, the vertical support rod of the inverted "T"-shaped support structure is composed of two vertical rods arranged side by side. A jack seat and a pad seat are arranged sequentially from top to bottom between the upper parts of the two vertical rods arranged side by side. A jack is provided on the top of the jack seat. The output shaft of the jack passes downward through the jack seat and the pad seat and is connected to the top of the suspension screw.

[0011] By setting a rear lower crossbeam suspension structure at the rear upper crossbeam to connect the rear upper crossbeam and the rear lower crossbeam, and by setting jacks on the inverted "T"-shaped support structure, the problem of automatically operating the lifting and lowering of the bottom basket on the bridge deck can be achieved. On the one hand, this solves the technical problem of the original bottom basket lifting and lowering relying on manual lifting with chain hoists, which is complicated to operate and requires a lot of manpower. On the other hand, by combining the bottom basket template lifting structure with the rear lower crossbeam anchoring system, the technical problem of the difficulty in installing and dismantling the external slings of the web of the original rear lower crossbeam is solved.

[0012] As a further preferred embodiment of this utility model, there are two sliding beams supporting one side of the template support frame.

[0013] As a further preferred embodiment of this utility model, the corbel structure includes a reaction corbel body and a corbel longitudinal beam. The top of the reaction corbel body is welded to the back rib of the template structure. The front end of the bottom surface of the corbel longitudinal beam and the rear end of the bottom surface of the corbel longitudinal beam are respectively connected to the top surface of the front lower crossbeam and the top surface of the rear lower crossbeam. The reaction corbel body and the corbel longitudinal beam are connected by a corbel screw. The upper and lower parts of the corbel screw are provided with a washer-type nut fixing structure.

[0014] The corbel longitudinal beams are supported on the front and rear lower crossbeams. After the reaction corbel bolts are installed and tightened, the load of the flange formwork structure can be transferred to the front and rear lower crossbeams.

[0015] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects:

[0016] 1. In this solution, a rear lower crossbeam suspension structure is set on the rear upper crossbeam, and a template support longitudinal beam is set on the upper part of the rear lower crossbeam suspension structure. This forms an L-shaped hook structure on the upper part of the rear lower crossbeam suspension structure. During construction, the flange template is lowered and placed on the L-shaped hook structure, the front lower crossbeam, and the rear lower crossbeam. When moving, the movement of the template support longitudinal beam drives the sliding beam and the flange template structure to move synchronously. This solves the technical problem that the front sliding beam hanger is prone to tilting and bending when the flange template structure moves, which may cause the hanging basket to overturn.

[0017] 2. By establishing a rigid contact between the flange template structure and the upper crossbeam and bottom basket of the hanging basket, the flange template structure can move smoothly, solving the problem of the sliding beam trolley easily getting stuck and achieving the technical effect of smooth movement of the flange template structure.

[0018] 3. The support surface of the inverted "T" shaped support structure is used to support the template support beam, and such a support structure is stable.

[0019] 4. By setting a rear lower crossbeam suspension structure at the rear upper crossbeam, the rear upper crossbeam and the rear lower crossbeam are connected. Jacks are set on the inverted "T"-shaped support structure, thereby achieving the problem of automatic operation of the bottom basket lifting on the bridge deck. On the one hand, it solves the technical problem of the original bottom basket lifting relying on chain hoists for manual lifting, which is complicated to operate and requires a lot of manpower. On the other hand, by combining the bottom basket template lifting structure with the rear lower crossbeam anchoring system, it solves the technical problem of the difficulty in installing and dismantling the original rear lower crossbeam web external sling.

[0020] 5. The corbel longitudinal beams are supported on the front lower crossbeam and the rear lower crossbeam. After the reaction corbel bolts are installed and tightened, the load of the flange formwork structure can be transferred to the front lower crossbeam and the rear lower crossbeam.

[0021] 6. With the structure described above, the hanging basket does not require manual assistance in operating the flange travel system during its movement, saving time and effort and reducing labor intensity. Attached Figure Description
