A combined frame column formwork and its construction method

Abstract

The invention relates to a combined frame column formwork and a construction method thereof. The combined frame column formwork comprises L-shaped half formworks, supporting devices, connecting bolts, an operation platform, protective railings and split bolts, wherein the two L-shaped half formworks are used in combination, fixedly connected through the connecting bolts and reinforced by the split bolts; one end of each supporting device is fixed on the corresponding L-shaped half formwork, and the other end is fixed on the ground or a building floor surface; the operation platform and the protecting railings are arranged at the upper end of a frame column formwork consisting of the two L-shaped half formworks. The combined frame column formwork has the beneficial effects that construction is convenient, the mounting / dismounting progress is fast, the work efficiency is high, the rigidity of the formwork is high, the stability of the formwork is good, the problem of mold expanding can be solved, the engineering cost is reduced, and the engineering quality is improved.

Description

technical field [0001] The invention relates to the technical field of building engineering structure construction, in particular to a combined frame column formwork and a construction method thereof. Background technique [0002] In the process of building construction, frame column construction is a very important process, especially for large and high-rise buildings, frame column construction is even more important. At present, in the process of supporting frame column formwork in the construction stage of construction engineering structures, small pieces of wooden formwork or steel formwork are usually assembled manually, and four sides need to be pre-assembled. The labor intensity is high, the labor cost is high, and the installation and removal speed Slow, and the turnover times of multiple installation and disassembly are low; the length of horizontal support and diagonal brace cannot be adjusted, and it is inconvenient to find the alignment; ordinary diagonal brace n...

Problems solved by technology

At present, in the process of supporting frame column formwork in the construction stage of construction engineering structures, small pieces of wooden formwork or steel formwork are usually assembled manually, and four sides need to be pre-assembled. The labor intensity is high, the labor cost is high, and the installation and removal speed Slow, and the turnover times of multiple installation and disassembly are low; the length of horizontal support and diagonal brace cannot be adjusted, and it is inconvenient to find the alignment; ordinary diagonal brace needs to support 3 or 4 surfaces, which also has high labor intensity and high labor cost. The problem of slow demolition speed; the anchorage generally adopts the method of cutting off the pre-embedded steel bar head after demolishing the formwork, and the construction is troublesome

Moreover, this common method is not easy to ensure the rigidity and stability of the formwork, and cannot guarantee the verticality and flatness of the concrete surface, and it is easy to cause mold expansion.
