Detailed Description
The invention is further described below, but the scope of protection of the invention is not limited thereto:
the invention relates to a construction process for a buckling-restrained rapid frame combined modified ABS plastic formwork, which comprises the following steps:
1) preparation before construction: preparing materials, instruments and the like for standby;
2) the plastic template and quick assembling and disassembling type bearing frame supporting system mainly comprises a novel plastic plate serving as a template, a novel quick assembling and disassembling type bearing frame supporting body serving as a supporting die frame, and an adjustable supporting bracket and a double-steel-pipe main keel 50mm x 100mm batten secondary keel which are comprehensively matched for supporting a cast-in-place concrete top plate.
3) The supporting vertical pipes and the cross rods of the fast assembling and disassembling type bearing frame supporting system are all made of phi 48 multiplied by 3.0 steel pipes, the vertical rods are 2600mm, 2450mm, 2350mm, 2250mm and 2100mm in specification, and the horizontal cross rods are 500mm, 700mm, 1000mm and 1200mm in specification.
4) The vertical rods and the cross rods of the supporting system are matched through plugs and socket inserting cards and are freely integrated according to different layer heights and the size of the opening, so that a supporting lattice-template support with a standard structural size is formed.
5) According to the position line of the ejection, an upright rod is arranged on the batten with the thickness of 50mm, the length of the upright rod is determined according to the floor height, the maximum exposed length of the adjustable jacking, the thickness of the template and the batten and other factors, and the length is 'floor height-floor thickness-template thickness-batten thickness-steel pipe diameter-cushion block thickness-adjustable jacking exposed length'.
6) The vertical rod is installed while the horizontal rod is installed, and the horizontal rod is driven into the socket of the vertical rod by a hammer. When the horizontal rods are installed, the horizontal floor sweeping rods are installed firstly, then the horizontal rods in the second row are installed to form a quadrilateral supporting lattice, and the rest supporting lattices are supported along the supported horizontal supporting lattices according to the mutually vertical or horizontal principle to form a full-hall supporting frame body.
7) The length of the vertical rod extending out of the central line of the horizontal rod at the top layer is not more than 600mm, and if the length of the vertical rod exceeds the specified range, a horizontal rod is additionally arranged at the position 500m below the free end of the vertical rod by using a fastener and a steel pipe.
8) The top of each upright stanchion is provided with an adjustable support bracket, the length of the adjustable support bracket inserted into the upright stanchion is not less than 300mm, the kneading length of a support bracket screw rod and a nut is not less than 4-5 buttons, the length of the support bracket screw rod is not less than 3/5 screw rods, and the length of the support bracket screw rod extending out of the upright stanchion is not more than 200 mm.
9) After the batten secondary keels are leveled to the designed elevation, plastic formworks are laid from one side to the other side or from the middle to the two sides according to the size of the opening, and the plastic formworks and the batten secondary keels are tightly combined through nails. In the laying process, the elevation of the column head plate is required to be leveled along with laying, the elevation can not be adjusted after the template is laid by tens of millions, and no gap is left between the column head plate and the top plate.
10) The stair construction formwork comprises a bottom formwork, side formworks are arranged on two sides of the bottom formwork, the stair construction formwork further comprises a separation formwork, locking mechanisms are arranged on two sides of the separation formwork, locking holes are formed in the side formworks, magnets are arranged at the bottoms of the locking holes, when the separation formwork is installed between the side formworks on the two sides, the locking mechanisms are aligned to the locking holes, the locking mechanisms enter the locking holes after attraction of the magnets, the separation formwork is installed between the formworks on the two sides conveniently and quickly, when the formwork needs to be dismantled, the side formworks are dismantled firstly, the side formworks are only fixedly connected with the bottom formwork, the side formworks are in sliding connection with the separation formwork, and therefore the stair construction formwork is easier to dismantle compared with a traditional formwork fixed by iron nails.
