Embodiment Construction

[0041] 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.

[0042] 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.

[0043] In order to make...

Abstract

The invention provides a concrete high pier construction formwork device, and belongs to the technical field of building equipment. The concrete high 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 template and an outer template; the supporting system comprises an enclosure truss, a plurality of outer lifting frames and a plurality of inner lifting frames; the enclosure truss is arranged outside the outer template; a distance between the enclosure truss and the outertemplate is 220mm to 280mm; the plurality of outer lifting frames are all fixedly connected with the enclosure truss, the outer template is mounted on the outer lifting frames, and the inner templateis mounted on the inner lifting frames; the hydraulic lifting system is used for driving the inner lifting frames and the outer lifting frames to reciprocate so as to enable the enclosure truss, theouter template and the inner template to synchronously move; the operation platform is positioned in a cavity formed by the surrounding of the inner template and positioned on the enclosure truss. Theformwork device is compact in integral structure and firm and reliable in structure; in the lifting process, a formwork is more uniform in stress and more convenient and rapid to lift.

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...
