Supporting positioning formwork device for construction of beam column joint of prefabricated building and application thereof

Abstract

The invention provides a supporting positioning formwork device for construction of a beam column joint of a prefabricated building and an application thereof. The supporting positioning formwork device comprises a supporting main body having a right-angle angle steel shape. The supporting main body includes a horizontal structural surface, a vertical mounting surface and a triangular support surface, a plurality of fixing bolts extending outwards are mounted on the vertical mounting surface, two strip-shaped overturning positioning steel plates are hinged and mounted on the edge part of the horizontal structural surface connected with the vertical mounting surface, the overturning positioning steel plates are distributed along two side edges of the horizontal structural surface, the platesurfaces of the free ends of the overturning positioning steel plates are provided with opposite-pull reserved holes, and the overturning positioning steel plates can be overturned by 90 degrees on the horizontal structural surface relative to the hinged position as a rotating axis. The supporting positioning formwork device is a three-in-one construction device that can simultaneously achieve the supporting and positioning of a prefabricated beam column and construction of a poured formwork, and not only is scientific and reasonable in structure and high in practicality, but also effectivelyreduces construction cost and improves construction efficiency and precision.

Problems solved by technology

[0002] At present, there are no effective positioning measures when hoisting the main girder of prefabricated buildings. Generally, the line is sprung on the column head and then placed and corrected according to the sprung line during hoisting; the main girder is generally supported by a support frame, and it needs to be adjusted It brings a lot of inconvenience in the position; the concrete formwork at the beam-column joint position usually adopts traditional wooden formwork or shaped steel formwork, and there are many procedures during installation and removal, which is cumbersome and cannot effectively guarantee the quality and appearance of the concrete at the joint

[0003] At present, the support frame is generally used for support, which consumes a lot of turnover materials, requires manual erection and dismantling, and is easy to lose stability. It is troublesome when the support frame is placed inaccurately and needs to be adjusted. The operation is difficult and the progress of the beam cannot be made be effectively guaranteed

[0004] In positioning, at present, the spring line is generally used on the column head. When hoisting the main beam, the two sides of the beam are used to align the spring line for positioning. There will be errors in man-made line springing and alignment errors, and after alignment It may also cause later errors due to later collisions, which are often difficult to adjust in actual construction and have a greater impact on the construction progress

When building formwork before pouring, traditional wooden formwork or shaped steel formwork is usually used to close the formwork; when traditional wooden formwork is used, the operating frame and support frame need to be erected separately, which takes up materials and is troublesome to assemble and disassemble, occupying a lot of lower space, and wood It is difficult to effectively control the dimensional accuracy of the formwork in a small area, which often results in insufficient visual quality or local deformation after the concrete is poured; When the steel mold is installed alone, there will be human error and late error. If there is a collision and deformation during the construction process, it will be difficult to correct it on site
