Detailed ways

The present utility model can be explained in detail through the following examples, and the purpose of disclosing the present utility model is to protect all technical improvements within the scope of the present utility model.

A stair tread for a stair mold described in conjunction with the accompanying drawings 1-2 is composed of a plurality of step templates 1 correspondingly connected in turn. The wedge blocks 4 are connected correspondingly. First, the butt surfaces of the two step templates 1 are in contact with each other, and the butt holes 1.5 on the butt surfaces are connected correspondingly, and then the pins 3 pass through the butt holes 1.5. When the wedge holes of the pins 3 pass through the butt holes 1.5 Then insert the wedge block 4 into the wedge hole to realize the docking of the stepping formwork 1. In addition, the back of the stepping formwork 1 is provided with a pin anti-lost device 2. When the stair mold is disassembled, the pin anti-lost device 2 can Collect the removed pins 3 and wedges 4, thereby preventing the pins 3 from being lost, and also making it more convenient for workers to use the pins 3 when installing the mold next time; the pin loss prevention device 2 includes a support rod 2.1, the support rod 2.1 The two ends of the support rod 2.1 are respectively connected to one side of the butt plate 1.4. The shaft of the support rod 2.1 is evenly provided with a plurality of through holes 2.2 for the pins 3 to be inserted through. The combination enables the pins 3 and the wedges 4 to be transported together with the step template 1, reducing the traditional steps of collecting the pins 3 and the wedges 4, facilitating the transportation of the pins 3 and the wedges 4, and also preventing the pins 3 and the wedges 4. The block 4 is lost, and the plurality of through holes 2.2 are provided with a fastening ring 2.3 for fixing the position of the pin 3. When the pin 3 passes through the through hole 2.2, it will also pass through the ring opening of the fastening ring 2.3, and pass through the fastening ring 2.3. The friction force between the ring mouth and the pin 3, so that the pin 3 can be fixed in the fastening ring 2.3, so that the nail body of the pin 3 is fixed in the through hole 2.2, and the pouring surfaces of the multiple step templates 1 are in contact with each other. The back corresponds to the tread surface that forms the stairs;

The stepping formwork 1 is set as a right-angle C-shaped structure, and the pouring surface of the horizontal end 1.1 of the stepping formwork 1 corresponds to the horizontal tread surface of the stairs, and the other bent end of the stepping formwork 1 is set as the vertical end 1.2. The head end of the pouring surface at the lower end of the step formwork 1 is provided with a strip-shaped boss 1.6. When the concrete is solidified, the corresponding position of the tread surface of the stairs and the strip-shaped boss 1.6 will become a groove. Strips and other objects can improve the anti-skid performance of the horizontal tread surface of the stairs. In particular, the strip bosses 1.6 are set as two parallel lines, which can further improve the anti-skid performance of the horizontal tread surface of the stairs;

The end face of the horizontal end 1.1 is extended with a butt plate 1.3, and the back of the end of the vertical end 1.2 of the step formwork 1 is vertically provided with a butt plate 1.3. 1 Both sides of the back side are provided with side butt plates 1.4, and the side butt plates 1.4 are used for the butt joint between the step formwork 1 and the side plates in the stair mold. In addition, the back of the bending part of the step formwork 1 is provided with Reinforcing ribs 1.7 are provided to further enhance the structural strength of the step formwork 1. The surfaces of the two butt plates 1.3 are provided with a plurality of butt holes 1.5, and the vertical ends of the butt plates 1.4 on both sides are respectively provided with a pair of butt holes. 1.5. Step formwork 1 is correspondingly connected to the side plate through the docking hole 1.5. Due to the regular arrangement of the docking holes 1.5 on the stair tread plate after the docking of multiple stepping formwork 1, the position of the corresponding hole on the side formwork can be easily determined, thereby simplifying the The processing procedure of the side formwork is completed. According to the needs, the lateral ends of the butt plates 1.4 on both sides of the step formwork 1 are respectively provided with a butt hole 1.5. 1.4 On the connection line of the vertical end docking hole 1.5, since the side plate is composed of multiple side formwork butt joints, and the positions of the holes corresponding to the connection between the multiple side plates and the bottom plate are fixed, so if the side docking plate 1.4 Arbitrary setting of the butt holes 1.5 will make the positions of the holes corresponding to the butt holes 1.5 on each side plate different, which will lead to different widths of the side plates, thereby increasing the material cost; The plates 1.3 are all made of aluminum alloy plates, which not only reduces the weight of the formwork, but also does not reduce the structural strength of the step formwork 1 .

The part not described in detail in this utility model is the prior art.
