Embodiment Construction

[0036] The present invention will be further described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0037] Such as Figure 1-10 , a movable track lifting device, the lifting device of this embodiment is used to lift the track unit 3, so that the track unit 3 can be reused repeatedly, reducing the cost of the track structure. The hoisting device of the present embodiment comprises a fixed truss 1 and a movable truss 2, such as figure 1 As shown, the fixed truss 1 of this embodiment is anchored on the finished concrete surface through embedded parts, and the movable truss 2 is a movable truss structure connected to the fixed truss 1 in a longitudinally movable manner.

[0038] Such as figure 2 As shown, the lower end of the fixed truss 1 is provided with a longitudinal guide rail 4 extending in the longitudinal direction, the movable truss 2 is provided with a sliding shoe 5 slidingly connected to the longitudinal guide rail 4, and...

Abstract

The invention relates to the technical field of building construction structures, in particular to a movable track lifting device. The movable track lifting device comprises fixed trusses which are anchored on the concrete surface. The movable track lifting device is characterized by further comprising moving trusses. Each moving truss is of a moving truss structure which can be movably connectedto the corresponding fixed truss in the longitudinal direction. Clamping structures which are used for clamping track unit parts are arranged on the moving trusses, and each clamping structure is of atrack unit part temporary fixing structure which can be movably connected to the corresponding moving truss in the transverse direction. Hoisting structures which are used for hoisting the track unitparts in the vertical direction are installed on the fixed trusses. The movable track lifting device is simple in structure and convenient to operate, the track unit parts which are used can be conveniently taken down from the concrete surface and hoisted to the to-be-constructed position, and the movable track lifting device can be applied to various high-rise concrete buildings with the complexstructures, and is broad in application range.

Description

technical field [0001] The invention relates to the technical field of building construction structures, in particular to a movable rail lifting device. Background technique [0002] At present, the intelligent hydraulic jacking formwork system has been widely used in the field of super high-rise construction, and its use effect in terms of construction safety, efficiency, and environmental protection is obvious to all. By anchoring the track on the surface of the poured concrete, the hydraulic jacking formwork can climb up along the track to gradually complete the pouring construction of the super high-rise building. The current track is generally assembled sequentially by a plurality of track unit elements, and the track unit elements are anchored to the concrete surface through pre-embedded parts embedded in the concrete surface. In order to reduce the cost of the track structure, the track units after the formwork passes are usually removed, and then hoisted to the top ...
