Detailed Description
The embodiments of the present invention will be described in detail with reference to the accompanying drawings, and the embodiments are implemented on the premise of the technical solution of the present invention, and detailed embodiments and specific operation procedures are given, but the scope of the present invention is not limited to the following embodiments.
As shown in figures 1 and 2, the portable steel-wood mixed template for the circular arc section of the oblique web plate of the continuous beam consists of a wood template and a prefabricated steel template. The plank sheathing includes that thickness is 1.5 cm's bottom plate 1, oblique web 2 and pterygoid lamina 3, and it is fixed on the secondary joist that sets up along continuous roof beam lengthwise direction, specifically, the edge of bottom plate 1 is fixed on primary joist 4, and the lower limb of oblique web 2 is fixed on secondary joist 5, and the top edge of oblique web 2 is fixed on tertiary joist 6, and the inward flange of pterygoid lamina 3 is fixed on fourth fossil fragments 7. The prefabricated steel formwork comprises a first arc plate 8 and a second arc plate 9 which are prefabricated by adopting 3mm steel plates, the specifications of the first arc plate 8 and the second arc plate 9 are the same, the length of a single block is 1.5m, the arc length is 47.1cm, the arc radius is 50cm, a row of mounting holes 10 are uniformly distributed on the inner side 2cm of the upper edge and the lower edge of each arc plate, the center distance of the adjacent mounting holes 10 in the same row is 30cm, and the mounting holes 10 are used for penetrating through connecting screws. The first arc plate 8 is positioned between the bottom plate 1 and the inclined web plate 2, the lower edge of the first arc plate is fixed on the first secondary keel 4 through a screw, and the upper edge of the first arc plate is fixed on the second secondary keel 5 through a screw; the second circular arc board 9 is located between oblique web 2 and pterygoid lamina 3, and its lower limb passes through the fix with screw on third keel 6, and the top edge passes through the fix with screw on fourth keel 7. When the secondary joist can not closely laminate with the first circular arc board 8, the second circular arc board 9 of its top, need the installation to adjust stuff 11, at this moment, the screw passes and adjusts stuff 11 and link to each other with the secondary joist.
