[0016] In order to make the purpose, technical scheme and advantages of the present application clearer, the technical scheme in the present application will be described clearly and completely below in combination with the drawings of the present application.

[0017] The technical scheme of the present application will be described clearly and completely below in combination with embodiments, obviously, the described embodiments are part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor belong to the protection scope of the present application.

[0018] In the description of the present application, it should be understood that the terms "center", "longitudinal", "transverse", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise" and the like indicate the orientation or positional relationship shown in the drawings, and are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation of the present application.

[0019] ​In addition, the terms "first", "second", "third", etc. are used only for descriptive purposes and should not be construed as indicating or implying relative importance or an indicated number of technical features. Therefore, the features defined as "first", "second", "third", etc. can explicitly or implicitly include one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited. In addition, the terms "mounting", "connecting", "connecting" should be broadly understood, for example, it can be fixed connection, or detachable connection, or integral connection; it can be mechanical connection, or electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, or the communication between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0020] As shown in the embodiment, Figures 1-3 A sinking toilet combined formwork system includes a steel formwork 1 and a wood formwork 2, both of which are rectangular frame structures. The steel formwork 1 includes a lower frame 11 and an upper frame 12. The cross section of the lower frame 11 is a quarter circular arc structure, and the cross section of the upper frame 12 is an L-shaped structure with an opening facing the outer side. The end portions of the lower frame 11 and the upper frame 12 are connected to each other. The wood formwork 2 is sleeved in the opening on the outer side of the upper frame 12, and the outer side of the wood formwork 2 is tangent to the lower frame 11.

[0021] The wood formwork 2 is sleeved in the opening on the outer side of the upper frame 12, so that the wood formwork 2 is connected with the steel formwork 1 to form a whole formwork for the cast-in-place concrete construction of the toilet. Since the cross section of the lower frame 11 is a quarter circular arc structure, the circular arc part of the toilet corner can be constructed together during the cast-in-place concrete construction, the forming effect is good, and secondary construction is not required, thereby reducing the construction process, improving the construction efficiency, and reducing the construction period. The outer side of the wood formwork 2 is tangent to the lower frame 11, which can prevent the concrete from appearing to be misaligned. The bottom steel formwork 1 has large rigidity, and is less likely to produce the phenomenon of formwork expansion compared with the traditional formwork formwork system.

[0022] In a specific embodiment, the steel formwork 1 is assembled by four steel formwork 1 units. The inner side of the upper frame 12 of each steel formwork 1 unit is fixed with three sleeves 4. The sleeves 4 adjacent to each other in the four steel formwork 1 units are connected by a first support rod 5, and the sleeves 4 in the middle are connected by a second support rod 6. The four steel formwork 1 units can be assembled and disassembled by the first support rod 5, the second support rod 6 and the sleeves 4. The disassembly is convenient, and the rigidity of the steel formwork 1 can be further supported and increased, and the phenomenon of formwork expansion is less likely to occur.

[0023] In a specific embodiment, the distance between the three sleeves 4 is within 1 m, and the outer diameter of the first and second support rods 5 and 6 is 3 mm smaller than the inner diameter of the sleeves 4.

[0024] In a specific embodiment, the inner side of the wooden formwork 2 is provided with wooden frame back beads 7, and the opposite wooden frame back beads 7 are supported by third support rods 8, and the wooden formwork 2 is additionally reinforced by the wooden frame back beads 7 and the third support rods 8.

[0025] In a specific embodiment, the radius of the arc of the lower frame 11 is 50 mm.

[0026] The above embodiments are only used to illustrate the technical solutions of the present application, and not to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that the technical solutions recorded in the foregoing embodiments can still be modified, or some technical features can be replaced by equivalents; and these modifications or replacements do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application.
