Embodiment Construction

[0028] The invention provides a mobile formwork suitable for multi-width beams and a construction method, which reduces the number of passing holes, is simple to operate, and improves the safety of bridge construction. The present invention will be described in detail below in conjunction with specific embodiments and accompanying drawings.

[0029] Such as figure 1 and Figure 5 As shown, the present invention provides a mobile formwork suitable for multiple beams, including a main beam 11 , a hanger 13 and a pouring form 12 .

[0030] A pair of main girders 11 that are consistent with the length direction of the bridge are fixedly connected, and guide beams 14 are provided at the front and rear ends, and front legs 15, middle legs 16 and rear legs 17 are slidably provided on the bottom surface.

[0031] Such as figure 2 , image 3 and Figure 4 As shown, the hanger 13 is arranged outside the two main girders 11, and the bottom surface of the hanger 13 is provided with ...

Abstract

The invention discloses a movable formwork suitable for multiple beams and a construction method. The movable formwork comprises main beams, a hanging bracket and a casting mold. The direction of the pair of fixedly connected main beams is identical with the length direction of a bridge. Guide beams are arranged at the front end and the rear end of each main beam. A front supporting leg, a middle supporting leg and a rear supporting leg are arranged on the bottom face of each main beam in a sliding mode. The hanging bracket is arranged on the outer sides of the two main beams. A through track beam is arranged on the bottom face of the hanging bracket. The casting mold is movably arranged on the lower side of the hanging bracket and comprises a side mold body and a bottom mold body vertically arranged on the lower side of the side mold body. Reverse hooking wheels are arranged on the upper portion of the side mold body. The cross section of the track beam is in an I shape, and the reverse hooking wheels are movably arranged in an I-shaped cavity of the track beam. By the adoption of only one movable formwork, the multiple transverse beams are cast and transversely moved; besides, the position of the movable formwork does not need to be moved in the transverse direction, materials are saved, the number of hole passing times is reduced, operation is easier, and the safety of bridge construction is improved.

Description

technical field [0001] The invention relates to the field of bridge construction, in particular to a mobile formwork suitable for multi-width beams and a construction method. Background technique [0002] Mobile formwork is widely used in the construction of concrete bridges. For bridge projects with multiple concrete beams arranged horizontally, the same number of mobile formwork as the number of beams is generally used for construction. Each mobile formwork must pass through holes, so the total The number of holes is more, or use a mobile formwork to complete the construction of all the concrete beams in one direction, then remove the mobile formwork and reinstall it to other sections, and then construct a section in the same way, and so on. , since there is only one mobile formwork, the number of vias to move from one frame to other frames is more than the former method. The former method uses more mobile formwork, which wastes resources and manpower. Although the latter...
