Description

Technical Field

[0001] The invention relates to the field of equipment for hanging basket construction, in particular to a trackless triangular hanging basket flange template walking device and a walking method using the same. Background Art

[0002] When constructing a continuous beam (rigid frame) bridge, a hanging basket is usually used for cantilever casting. During cantilever casting, the hanging basket is first assembled on the completed segment 0, and then the concrete pouring is completed on the hanging basket formwork system 4. During the construction, the hanging basket will move forward with the walking system. When the closure construction at the mid-span is completed, the hanging basket is removed and the cantilever casting is completed.

[0003] In the prior art, the movement of the hanging basket is usually carried out by pushing the main longitudinal beam with a hydraulic jack, and the flange formwork is usually moved by setting a sliding beam, a sliding beam trolley and a hanging rod. The front end suspends the sliding beam on the front upper cross beam through the hanging rod, and the rear end is fixed to the cast section through the sliding beam trolley. The movement of the front upper cross beam causes the front hanging rod to tilt and generate a horizontal force to drive the flange formwork to move. During the walking process, the front hanging rod often tilts and breaks, the sliding beam trolley does not roll smoothly, causing the formwork to jam, etc., which leads to the overturning of the hanging basket flange formwork, and the safety is low. Summary of the invention

[0004] The purpose of the present invention is to provide a trackless triangular hanging basket flange formwork walking device and a walking method using the same, so as to solve the problem that the existing flange formwork is prone to overturning during the walking process.

[0005] In order to solve the above technical problems, the present invention adopts the following technical solutions: A trackless triangular hanging basket flange formwork walking device, comprising a diamond 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 diamond truss is connected to the top surface of the already poured section. The front end and the middle part of the diamond 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 diamond truss is connected to a front lower crossbeam through the front lower crossbeam suspension structure. The rear upper crossbeam of the diamond 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 top of the sliding beam front suspension support structure and the top of the sliding beam rear suspension support structure are respectively connected to the front upper crossbeam and the already poured section. The bottom surface of the support part of the formwork support frame is in contact with the top of the sliding beam passing through the sliding beam front suspension support structure and the sliding beam rear suspension support structure. The formwork structure is arranged 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 arranged inward at the bottom of the sliding beam. The direction in which the formwork support crossbeam is arranged is perpendicular to the direction in which the sliding beam is arranged. The bottom of the back rib of the formwork structure is provided with a bracket structure. The bracket structure is fixedly connected to the front lower crossbeam and the rear lower crossbeam.

[0006] In this solution, by setting a rear lower crossbeam suspension structure on the rear upper crossbeam, and then setting a formwork support crossbeam on the upper part of the rear lower crossbeam suspension structure, an L-shaped hook structure is formed on the upper part of the rear lower crossbeam suspension structure. During construction, after the flange formwork is lowered, it is placed on the L-shaped hook structure, the front lower crossbeam and the rear lower crossbeam. During walking, the synchronous walking of the sliding beam and the flange formwork structure is driven by the walking of the formwork support crossbeam, solving the technical problem that the front sliding beam suspension rod is prone to tilt and bend during the walking of the flange formwork structure, which may cause fracture and may lead to the overturning of the hanging basket.

[0007] As a further preference of the present invention, the rear lower crossbeam suspension structure includes an inverted "T" - shaped support structure, a suspension screw rod and a suspension strap arranged in sequence from top to bottom. One end of the bottom surface of the formwork support longitudinal beam is installed on the support surface at the lower part of the inverted "T" - shaped support structure.

[0008] The support surface of the inverted "T" - shaped support structure is used to support the formwork support crossbeam, and such a support structure is stable.

[0009] As a further preference of the present invention, the vertical support rod of the inverted "T" - shaped support structure is composed of two vertically arranged rod bodies arranged side by side. Between the upper parts of the two vertically arranged rod bodies, a jack seat and a backing plate seat are successively arranged from top to bottom. The top of the jack seat is provided with a jack. The output shaft of the jack passes through the jack seat and the backing plate seat downward and is connected to the top of the suspension screw rod.

[0010] By setting a rear lower crossbeam suspension structure at the rear upper crossbeam, connecting the rear upper crossbeam and the rear lower crossbeam, and installing a jack on the inverted "T" - shaped support structure, the problem of automatically operating the lifting of the bottom basket on the bridge deck is achieved. On the one hand, it solves the technical problems of the original manual lifting of the bottom basket by chain hoists, which is complex in operation and requires a high level of manpower. On the other hand, by integrating the lifting structure of the bottom basket formwork and the anchoring system of the rear lower crossbeam, it solves the technical problem of the difficult installation and removal of the outer sling on the web of the original rear lower crossbeam.

[0011] As a further preference of the present invention, there are two sliding beams supporting one - side formwork support frames.

[0012] As a further preference of the present invention, 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 formwork structure. The front end 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 corbel screws, and pad - type nut fixing structures are provided at both the upper and lower parts of the corbel screws.

[0013] The corbel longitudinal beam is supported on the front lower crossbeam and the rear lower crossbeam. After installing and tightening the reaction corbel screws, the load of the flange formwork structure can be transferred to the front lower crossbeam and the rear lower crossbeam.

[0014] A method of walking using any one of the above - mentioned trackless triangular hanging basket flange formwork walking devices includes the following steps: A. Lower the hanging basket bottom basket structure and complete the conversion of the main longitudinal beam walking system of the hanging basket; B. Control the descent of the sliding beam by using the suspender of the sliding beam suspension support structure, thereby lowering the formwork structure so that the formwork support crossbeam falls onto the support surface of the inverted "T" - shaped support structure above the rear lower crossbeam suspension structure; C. Then, install and tighten the corbel screws of the corbel structure to transfer the flange formwork load to the front and rear lower crossbeams; D. Remove the suspenders of the sliding beam suspension support structure, and finally, walk the formwork structure into place.

[0015] Compared with the prior art, the present invention can achieve at least one of the following beneficial effects: 1. In this solution, by setting a rear lower crossbeam suspension structure on the rear upper crossbeam and then setting a formwork support longitudinal beam above the rear lower crossbeam suspension structure, an L - shaped hook structure is formed above the rear lower crossbeam suspension structure. During construction, after lowering the flange formwork, it is placed on the L - shaped hook structure, the front lower crossbeam, and the rear lower crossbeam. During walking, the walking of the formwork support longitudinal beam drives the synchronous walking of the sliding beam and the flange formwork structure, solving the technical problem that the front sliding beam suspenders are prone to tilt and bend during the walking of the flange formwork structure, which may cause fracture and may lead to the overturning of the hanging basket.

[0016] 2. The rigid contact between the flange formwork structure and the rear upper crossbeam and the bottom basket of the hanging basket enables the flange formwork structure to walk smoothly, solves the problem that the sliding beam trolley is prone to jamming, and achieves the technical effect of the smooth walking of the flange formwork structure.

[0017] 3. The supporting surface of the inverted "T" - shaped support structure is used to support the formwork support crossbeam, and such a support structure is stable.

[0018] 4. By setting a rear lower crossbeam suspension structure at the rear upper crossbeam, connecting the rear upper crossbeam and the rear lower crossbeam, and setting a jack on the inverted "T" - shaped support structure, the problem of automatically operating the lifting of the bottom basket on the bridge deck is achieved. On the one hand, it solves the technical problems that the original lifting of the bottom basket relied on manual lifting with chain hoists, with complex operations and high manpower requirements. On the other hand, by integrating the lifting structure of the bottom basket formwork and the anchoring system of the rear lower crossbeam, the technical problem of the difficult installation and removal of the outer sling of the rear lower crossbeam web is solved.

[0019] 5. The bracket longitudinal beam supports on the front lower crossbeam and the rear lower crossbeam. After installing and tightening the reaction bracket screw, the load of the flange formwork structure can be transferred to the front lower crossbeam and the rear lower crossbeam.

[0020] 6. With the structure in the above - mentioned scheme, during the walking process of the hanging basket, there is no need for manual auxiliary operation of the flange walking system, which saves time and effort and has a low labor intensity. BRIEF DESCRIPTION OF THE DRAWINGS
