Detailed Description
Specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.
As shown in fig. 1, fig. 2 and fig. 3 together, the utility model provides a many high-rise building stair formwork structure, including side form 1 and stair step founds mould 2. The side form 1 comprises a first multi-layer wooden formwork 10 of 18mm thickness. The upper end and the lower end of the inner side of the first multilayer wooden template 10 are respectively provided with a first batten 11 with the thickness of 30mm as a stiffening plate. According to the layout of the detailed stair design drawing, the position of the stair step vertical mold 2 is determined on the side mold 1, and the clamping groove 12 is formed in the position corresponding to the stair step vertical mold 2. The clamping groove 12 is vertically arranged on the side die 1, and the bottom of the clamping groove 12 is horizontally arranged. The stair step vertical mold 2 is clamped in the clamping groove 12, and the width of the clamping groove 12 is equal to the thickness of the stair step vertical mold 2 plus 1-2 mm. The stair step vertical formwork 2 comprises two second multilayer wood modules 20 which are oppositely arranged and a plurality of second battens 21 which are arranged between the two second multilayer wood formworks 20. The second battens 21 are sequentially arranged along the height direction of the two second multilayer battens 20, and the two second multilayer battens 20 are connected through the second battens 21. In this embodiment, the second multi-layer plank sheathing 20 is a multi-layer plank sheathing with a thickness of 16mm, the second batten 21 is a batten with a thickness of 30mm, and the two second multi-layer plank sheathing 20 and the plurality of second battens 21 are spliced to form the stair tread sheathing 2 with a thickness of 62 mm.
If a shear wall is arranged on one side of the stair, as shown in fig. 4, 5 and 6, a step cut is determined and manufactured at the bevel edge position below the shear wall template 3 at the position where the shear wall template is connected with the stair according to the step width and height, and a third batten 4 with the thickness of 30mm is used as a stiffening plate at the edge of the step cut. The side face, opposite to the stair step template 2, of the third batten 4 is provided with 2 first limiting holes 40, and the diameter of each first limiting hole 40 is 15mm, and the depth of each first limiting hole is 50 mm. Meanwhile, 2 second limiting holes 210 corresponding to the 2 first limiting holes 40 are also formed in the second battens 21 of the stair step template 2, and the diameter of each second limiting hole 210 is 15mm and the depth of each second limiting hole is 50 mm. And then reinforcing steel bars with the diameter of 14mm and the length of 100mm are used as limiting rods to be inserted into the first limiting holes 40 and the second limiting holes 210 for limiting so as to connect the shear wall template 3 and the stair step template 2 and prevent the displacement of the shear wall template and the stair step template in the construction process. The utility model discloses following beneficial effect has at least: the utility model discloses use high-rise or multilayer concrete cast-in-place stair construction, can draw materials on the spot, easy and simple to handle in a flexible way, the turnover number of times is high, and the stair concrete shaping is effectual, and the rigidity is big, dislocation, indeformable, safe and reliable.
The invention is described above by way of example with reference to the accompanying drawings. However, it will be appreciated by those skilled in the art that modifications may be made to the invention as described above without departing from the scope of the invention.
