Embodiment Construction

[0037] In the existing technology, the sliding form construction technology is adopted, and the formwork device has a large one-time investment, which has certain restrictions on the facade shape of the structure. The structural design must also be coordinated according to the characteristics of the sliding form construction, and in the construction organization management, A scientific management system and a large number of professional teams are required, and the construction cost is high.

[0038] In view of this, the designer of the present invention designed a formwork device for high concrete pier construction. The formwork device has a simple and reasonable structure and low manufacturing cost. At the same time, the formwork device has a compact and firm structure. During the construction process, the climbing operation of the formwork system is flexible , The force balance of the whole device during the climbing process saves construction time.

Abstract

The invention provides a high concrete pier construction formwork device and belongs to the technical field of building equipment. The high concrete pier construction formwork device comprises a formwork system, a supporting system, a hydraulic lifting system and an operation platform. The formwork system comprises an inner formwork and an outer formwork. The supporting system comprises an enclosing truss, multiple outer lifting frames and multiple inner lifting frames, wherein the enclosing truss is arranged on the outer side of the outer formwork, and the distance between the enclosing truss and the outer formwork ranges from 300 mm to 500 mm; and the outer lifting frames are fixedly connected with the enclosing truss, the outer formwork is installed on the outer lifting frames, and the inner formwork is installed on the inner lifting frames. The hydraulic lifting system is used for driving the inner lifting frames and the outer lifting frames to move in a reciprocating manner, so that the enclosing truss, the outer formwork and the inner formwork move synchronously. The operation platform is located in a cavity defined by the inner formwork and on the enclosing truss. The formwork device is compact in whole structure, the structure is firm and reliable, and in the lifting process, the stress of the formworks is more even, and the formworks are lifted more conveniently and rapidly.

Description

technical field [0001] The invention relates to the technical field of construction equipment, in particular to a construction formwork device for high concrete piers. Background technique [0002] In the construction of highway bridges, the construction of high pier concrete is a very common construction technology, which has the advantages of simple operation, reliable quality and low cost. The construction technology of high pier concrete is relatively simple, and it is very critical to do a good job in the construction quality control of high pier concrete. In the prior art, the construction of high concrete piers often adopts the construction method of sliding form or overturning formwork. The sliding form is mainly composed of working platform, inner and outer formwork, concrete platform, working hanging rail and lifting equipment, etc. The inner and outer formwork is continuously lifted by the lifting equipment for concrete pouring. Turnover is the operation of usin...
