Detailed Implementation

[0021] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present utility model.

[0022] The following is in conjunction with the appendix Figure 1-4 This application will be described in further detail.

[0023] This application discloses a support mold for stair formwork. (Refer to...) Figure 1 , Figure 3 and Figure 4 A stair formwork support mold includes a base 1, an inner mold 3 movably connected to the top of the base 1, an outer mold 5 fixedly connected to the top of the base 1, the inner mold 3 and the inner side of the outer mold 5 movably connected, a pouring mold 6 fixedly connected to the inner cavity of the outer mold 5, a pouring groove 4 opened in the inner cavity of the pouring mold 6, and a cleaning mechanism 9 installed on the front side of the outer mold 5.

[0024] The cleaning mechanism 9 includes a limiting groove 902 and a cleaning plate 904. The limiting groove 902 is opened on the front side of the inner cavity of the outer mold 5. The bottom of the cleaning plate 904 is movably connected to the top of the inner mold 3 and the outer mold 5 respectively. A support rod 903 is movably connected to the bottom of the inner cavity of the cleaning plate 904. The support rod 903 is located on the front side of the outer mold 5.

[0025] Reference Figure 3 Both sides of the support rod 903 are fixedly connected to the fixing plate 901. The back side of the fixing plate 901 is fixedly connected to the front side of the outer mold 5, and one side of the fixing plate 901 is movably connected to the surface of the cleaning plate 904. The fixing plate 901 supports the position of the support rod 903, improves the stability of the support rod 903, and at the same time limits the movement of the cleaning plate 904 to prevent the cleaning plate 904 from moving too far and causing the cleaning plate 904 to detach from the surface of the support rod 903.

[0026] Reference Figure 3 and Figure 4The inner cavity of the limiting groove 902 is movably connected to the limiting plate 905. The front side of the limiting plate 905 is fixedly connected to the back side of the cleaning plate 904. The limiting plate 905 limits the movement of the cleaning plate 904, preventing the cleaning plate 904 from shifting during movement and thus affecting the cleaning effect of the cleaning plate 904.

[0027] Reference Figure 4 An anti-slip pad 906 is fixedly connected to the surface of the cleaning plate 904. The anti-slip pad 906 is made of rubber. The anti-slip pad 906 increases the contact area with the cleaning plate 904. At the same time, the anti-slip pad 906 made of rubber increases the friction force during contact with the hand, preventing the hand from slipping off during the movement of the cleaning plate 904.

[0028] Reference Figure 1 and Figure 2 A guide mechanism 2 is installed on the top of the inner cavity of the base 1. The guide mechanism 2 includes a guide groove 201, which is opened on the top of the inner cavity of the base 1. A guide plate 203 is movably connected to the inner cavity of the guide groove 201. The top of the guide plate 203 is fixedly connected to the bottom of the inner mold 3. The guide plate 203 guides the movement of the inner mold 3, improves the stability of the inner mold 3 during the movement, and allows the inner mold 3 to slide smoothly on the top of the base 1.

[0029] Reference Figure 2 A positioning rod 202 is fixedly connected to the inner cavity of the guide groove 201. The surface of the positioning rod 202 is movably connected to the inner cavity of the guide plate 203. The positioning rod 202 limits the guide plate 203 and prevents the positioning rod 202 from detaching from the inside of the guide groove 201 during movement, thereby causing the position of the inner mold 3 to shift.

[0030] Reference Figure 1 Both sides of the inner mold 3 and the outer mold 5 are movably connected with connecting plates 7. There are four connecting plates 7. The inner cavity of the connecting plate 7 is threaded with fixing bolts 8. The surface of the fixing bolts 8 is threadedly connected to the inner cavity of the inner mold 3 and the outer mold 5 respectively. By setting the connecting plates 7, when the surface of the fixing bolts 8 is inserted into the inner mold 3, the outer mold 5 and the connecting plate 7 respectively, the position of the inner mold 3 and the outer mold 5 can be fixed, so that the inner mold 3 and the outer mold 5 are stably attached together to provide support for the concrete inside.

[0031] Working principle: First, the inner mold 3 is pushed forward, which in turn moves the guide plate 203. The guide plate 203 guides the movement of the inner mold 3, improving its stability during movement. Simultaneously, the guide plate 203 slides on the surface of the positioning rod 202, which limits its movement and prevents it from detaching from the guide groove 201, thus avoiding displacement of the inner mold 3. The inner mold 3 continues until its front side is flush with the back side of the outer mold 5. Then, the fixing bolts 8 are inserted into the inner mold 3, outer mold 5, and connecting plate 7 to fix their positions. Concrete can then be poured into the pouring tank 4. After the concrete is poured, the anti-slip pad 906 is held and moved to the right. The movement of the anti-slip pad 906 causes the cleaning plate 904 to slide on the surface of the support rod 903. The support rod 903 guides the movement of the cleaning plate 904, allowing it to move in contact with the surface of the outer mold 5. During the movement of the cleaning plate 904, the limiting plate 905 will also move, limiting the movement of the cleaning plate 904 and preventing it from shifting position. At the same time, the cleaning plate 904 will contact the top of both the inner mold 3 and the outer mold 5 during its sliding process, which facilitates the scraping of excess concrete from the top of the inner mold 3 and the outer mold 5, preventing problems such as uneven scraping and uneven surface that may occur with manual scraping.

[0032] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
