Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a large steel mold for a truncated cone-shaped tight-hoop column. Background Art

[0002] During the rush stage of the main structure construction, the progress of the main structure construction needs to be advanced quickly, and the construction of tall independent columns needs to be completed in advance. This requires the pre-construction of large independent columns, the erection of operating frames for vertical steel bar construction, formwork construction and other erection and dismantling operations, and the process is complicated and lengthy.

[0003] At present, most of the independent columns actually used in construction are reinforced by formwork, wood, steel pipe (or butterfly buckle), and some are reinforced by steel formwork. When using formwork, wood, steel pipe (or butterfly buckle) for reinforcement, the reinforcement quality depends on the experience and quality of each worker. A slight negligence may cause the column to burst or expand, resulting in uneven quality; and the reinforcement period is long, affecting the construction period. Although the use of steel formwork for reinforcement solves the problem of uneven quality, the joints, steel formwork reinforcement, diagonal brace reinforcement, etc. still affect the column quality and construction period. Utility Model Content

[0004] The purpose of the utility model is to overcome the defects of the prior art and provide a large steel mold for a truncated cone-shaped tight-hoop column, which solves the problems of mold explosion and mold expansion in the prior art, greatly saves construction time, shortens the construction period, and achieves the effect of rapid molding of independent columns.

[0005] In order to achieve the above technical effects, the utility model provides a truncated cone type tight hoop column large steel mold, which includes:

[0006] The column frame comprises a column template for installing a column reinforcement cage and a plurality of support blocks evenly arranged around the column template, wherein the plurality of support blocks are fixedly connected to the column template to form a whole and form the column frame with a longitudinal cross-section shape of a truncated cone, and a through-length hollow groove is provided between two adjacent support blocks along the height direction of the support blocks;

[0007] A plurality of tightening rings are evenly clamped on the outer circumferences of the plurality of support blocks along the height direction;

[0008] A fixing plate is pre-buried in the structural plate, and the fixing plate is fixedly installed at the bottom of the column frame.

[0009] Preferably, the interior of the column formwork is hollow and forms an installation space for installing the column reinforcement cage.

[0010] Preferably, the number of the support blocks is four, and the four support blocks are respectively arranged on the four corners of the column formwork.

[0011] Due to the adoption of the above technical solution, the technical effects achieved by the utility model are:

[0012] 1) During the construction stage of the bottom structural slab of the independent column, a fixed plate for fixing the column foot is embedded in advance. During the construction of the independent column, a hollow truncated cone column frame is used to wrap the independent column reinforcement cage. The support block with a small top diameter and a large bottom diameter can directly serve as a diagonal brace. After the column frame is fixed with a segmented clamp ring, the independent column can be directly cast after completion, so that the super-high independent column can be quickly formed.

[0013] 2) It solves the problems of mold explosion and mold expansion in the existing practice, greatly saves construction time, and has the effect of reducing construction period costs. BRIEF DESCRIPTION OF THE DRAWINGS
