Problems solved by technology
[0002] Many hotels and office lobbies adopt cylindrical frame beam structure system. With the high standards of construction technology and quality requirements of design drawings, especially some large-diameter and super-long concrete cylindrical components, traditional cylindrical shaped steel formwork systems and wood formwork The system has many seams, time-consuming, high cost, and large one-time investment; it is heavy, manual movement is inconvenient, and vertical transportation machinery is required to assist transportation. At the same time, the frame beam support system is not easy to tie into an integral frame, so it is safe. The stability is not high, so a new formwork support system construction method that can solve these difficulties is needed to speed up the project progress and ensure safety

Embodiment Construction
[0024] In order to make the objectives, technical solutions and advantages of the present invention clearer, the present invention will be described in further detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present invention and are not intended to limit the invention.
[0025] The schematic diagram disclosed by the present invention is as Figure 1~5 As shown in the figure, a construction method of a cylindrical frame beam with an outer hoop as a whole, comprising the following steps:
[0026] Step 1, custom template 1: In the construction preparation stage, a semicircular template 1 with a height of 3m and a thickness of 18mm is customized in the factory, and the interface between the templates 1 is provided with grooves to ensure tight joints.
[0027] Step 2, formwork 1 installation: At the place where the steel frame supporting the column needs t...

The invention discloses a construction method of an outer hoop integraltie-typecylindrical frame beam. Theconstruction method comprises the following steps that step one, a formwork iscustomized; steptwo, theformwork isinstalled, and a steel rope strip is used for reinforcing and locking; step three, vertical steel pipesareinstalled for vertical positioning of the formwork; step four, a supporting frame ismounted to be connected witha cylindrical formworksysteminto a whole, and the integrity and stability of the cylindrical formwork system and a frame beam formwork systemare ensured; and stepfive, concrete is poured. Semi-circular bump grooves are formed in the connecting opening ends of the formwork, the installation of the formwork isfacilitated, and the tightness between the formworksisensured. The construction method adopts thesteel rope strip and the vertical steel pipe double formwork reinforcement system to ensure the reinforcement effect of a whole cylinder. Meanwhile, the cylindrical formwork system and the frame beam supporting frame are connected together by a transverse crossbar to ensure the integrity and stability of the cylindrical formwork system and the frame beam formwork supporting system. The construction method is simple in construction, stable in overall stability, high in turnover rate and good in safety.
