Instrumental climbing formwork for building vertical shaft/elevator shaft

Abstract

The invention discloses an instrumental climbing formwork for a building vertical shaft / elevator shaft, wherein an instrumental barrel formwork together with an upper-layer following-up platform, a power control box, a lower-layer follow-up platform, a center climbing formwork and a program circuit control cabinet constitute a combination unit. The inner cavity of the barrel formwork is provided with a girdle-type direct-pull retraction frame at a position corresponding to the center climbing frame; an anti-dumping structure is arranged at a joint between the barrel formwork and the follow-upplatform; timely locking structures are arranged between the follow-up platforms and a concrete wall; the program circuit control cabinet is used for controlling the retracting and stretching of the barrel formwork as well as the climbing of the formwork in a centralized and unified manner; and all the parts of the entire climbing formwork of the vertical shaft are fashion parts except for filling plates and back edges of the barrel formwork as well as panel structures and level replacement parts of the follow-up platforms. By means of the instrumental climbing formwork provided by the invention, the construction process for the barrel formwork of the vertical shaft represented as the elevator shaft is changed from the traditional tower crane lifting manual operation mode into a program circuit control mechanical operation mode, and the barrel formwork serving as the traditional construction amortization material becomes novel equipment of construction machines and tools.

Description

technical field [0001] The invention relates to a formwork for concrete building construction, in particular to a shaft formwork. Background technique [0002] Building shaft / elevator shaft climbing formwork, as a category of building formwork, has been reflected in building climbing formwork technology, but as a tool-type device, there is no precedent. The vertical shaft formwork represented by the elevator shaft still uses the manual operation mode of the tower crane to lift the formwork. Although the barrel mold structure has been greatly updated in recent years, the basic process mode has not undergone fundamental changes. With the continuous update of high-rise building construction technology, the traditional shaft mold technology has become the bottleneck of high-rise building rapid construction technology. [0003] Recently, the authorized tool-type self-climbing cylinder mold patents, such as China Patent No. 201020202357.5 "tool-type gear-driven self-climbing cyl...

Problems solved by technology

[0005] In addition, there are many deficiencies in several tool-type cylinder mold patents that have been authorized in the early stage, such as: 1. The T-shaped ball bearing shown in the Chinese invention patent No. ZL200810301142. The exposure in turn cannot ensure that the line bearings are evenly stressed during use;

[0006] 2. The positioning and connection structure of the hinged connecting rod of the tool-type barrel mold retractable frame does not meet the needs of changing the section of the barrel mold, so it is not enough to be a tool-type feature

[0007] 3. As a tool-type self-climbing tube formwork facility, how to reflect that all facilities meet the needs of the "tool-type" proposition, many existing patents are not clear enough, such as the relationship between climbing facilities, the height of climbing frames, etc.
