Template mutually lifting climbing apparatus and method

Abstract

The invention relates to a climbing formwork device with mutually-lifting formwork, comprising a formwork, a supporting body used for supporting the formwork and a power equipment which is used for driving the formwork to climb, wherein, the formwork is provided with a retractable cone-shaped supporting body which locates the formwork and bears dead load of the formwork, live construction load and wind load; the supporting body comprises a supporting rod which supports the formwork at one end of the formwork and tightens the formwork on a vertical backridge of the wall body by combining the supporting rod; during the process of operation, a lifting device provides the formwork with the power so that the formwork can climb; the supporting role supports the formwork at one end of the formwork so as to ensure that the formwork remains in a fixed position, cooperates with the vertical backridge to fix the formwork in a certain position and is positioned on and connected with the wall body by the retractable cone-shaped supporting body and a split bolt; is the formwork mutually serves as a motion orbit, namely, the non-climbing formwork serves as the motion orbit of the climbing formwork. The device has the advantages that the structure is simple and the corresponding operational platform is unnecessary to be too large during practical use, thus saving space, facilitating operation and having high working efficiency.

Description

technical field [0001] The invention relates to a climbing formwork, in particular to a device and method for realizing a climbing formwork by utilizing mutual climbing between templates. Background technique [0002] Climbing formwork is a very effective construction process for tall structures such as shear walls, frame core tubes and bridge piers. It has the ability of self-climbing and does not need hoisting machinery, so it reduces the lifting workload of transportation machinery during construction, thereby reducing the number of hoisting machinery, speeding up construction, and good economic benefits.

Problems solved by technology

[0003] At present, the existing domestic climbing forms mainly include climbing forms powered by lifting jacks and climbing forms powered by oil cylinders. Although these two climbing forms can be used in construction, for climbing forms powered by jacks, due to the During the molding process, the supporting rod is set on the top of the wall. Once there is a steel beam in the wall, the lifting frame cannot pass through. Even if the double beam can be disconnected, it will be limited by the clear width of the wall and the steel beam.

And when the inner and outer walls are climbing the formwork on the outside, the width of the upper frame and formwork plus the width of the formwork retreat, so that the width of the operating platform is relatively large, generally around 2500mm, the cantilever of the frame body is long, and the weight is heavy.

[0004] In addition, at the inner corner position, since the formwork on both sides needs to retreat more than 400mm, the corner formwork must be separated from the large formwork, and cannot rise with the large formwork, so it is easy to cause poor connection between the corner formwork and the large formwork, misalignment, and misalignment serious

[0005] However, due to the width of the upper frame body and template plus the width of the template retreat, the climbing formwork powered by the oil cylinder also makes the operating platform wider, generally around 2500mm. The formwork on both sides must retreat more than 400mm, the corner formwork must be separated from the large formwork, and cannot rise with the large formwork, resulting in poor connection between the corner formwork and the large formwork, serious misalignment and misalignment

[0006] In addition, the climbing formwork device driven by oil cylinders cannot climb synchronously as a whole, but must climb in blocks, and the climbing height difference must be controlled by manual adjustment of oil pipe valves. Safety issues are difficult to guarantee
