Problems solved by technology

[0007] With the continuous development of construction technology, the design span of the bridge is gradually increased, and the corresponding mobile formwork is correspondingly larger and heavier. The overall hoisting and lateral movement requires lifting equipment with a large lifting capacity to operate, and the organization is difficult. High site requirements and high cost
However, if the mobile formwork is disassembled and reinstalled, after the installation is completed, load preloading and evidence collection work will be required again, which will take a long time and is uneconomical

Embodiment Construction

[0042] The present invention will be further described below in combination with specific embodiments and accompanying drawings.

[0043] refer to figure 1 , 2 as shown, figure 1 The sequence of steps is from A to F, the first step: move forward vertically, the second step: move horizontally on one side, the third step: move vertically backward, the fourth step: move horizontally on the other side, the fifth step: move forward vertical shift. A method for the overall lateral movement of the main beam of the mobile formwork, which is used to move the main beam 2 of the mobile formwork spanning adjacent piers a and pier b to the position of pier a' and pier b' of the adjacent width, including in sequence The following steps:

[0044] 1) Set up the traverse device: refer to image 3 , 4 As shown, the traversing device includes at least two parallel traversing rails 3 arranged between pier a and pier b, a slide system on the traversing rail 3, and a pushing device, and the s...

Abstract

The invention discloses a method for transversely moving a mobile formwork girder integrally and relates to a construction method of an upper structure of a double-block separating bridge. The method is used for transversely moving a mobile formwork girder spanning over a pier a and a pier b which are adjacent to each other to a position spanning over a pier a' and a pier b' in the adjacent block. The method sequentially comprises the following steps: 1) erecting a transversely moving device; 2) longitudinally moving the mobile formwork girder forwards; 3) transversely moving the mobile formwork girder at one side; 4) longitudinally moving the mobile formwork girder backwards; 5) transversely moving the mobile formwork girder at the other side; 6) longitudinally moving the transversely moving the mobile formwork girder forwards. By adopting the method, dependence on large hoisting equipment and fields can be reduced and the integral transverse movement of the girder can be performed quickly in a narrow space under the bridge. At the same time, materials are saved, construction is simplified, safety and economy are realized, and the construction period is shortened.

Description

technical field [0001] The invention relates to a construction method for the superstructure of a double-width separated bridge, in particular to the overall lateral movement construction of the main girder of a mobile formwork frame with limited lifting capacity or space conditions. Background technique [0002] Traverse movement of traditional mobile formwork: [0003] The mobile formwork is the traditional bridge superstructure construction equipment. When the number of bridge spans is small, after the completion of a single construction, it is often necessary to move the width to another construction. The conventional method is: [0004] ① Use large-scale lifting equipment to lift the main beam of the mobile formwork from the corbel as a whole, hoist the corbels to the installation position in turn, and then hoist the main beam to the corbel after the installation is completed; [0005] ② Disassemble the mobile formwork structure and transfer it to the installation loca...
