[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments. The following description of at least one exemplary embodiment is actually only illustrative and is by no means intended to limit the present invention and its application or use. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0024] Unless otherwise specifically stated, the relative arrangement, numerical expressions and numerical values ​​of the parts and steps set forth in these embodiments do not limit the scope of the present invention. At the same time, it should be understood that, for ease of description, the sizes of the various parts shown in the accompanying drawings are not drawn according to the actual proportional relationship. The technology, methods and equipment known to those of ordinary skill in the relevant field may not be discussed in detail, but in appropriate cases, the technology, methods and equipment should be regarded as a part of the authorization specification. In all examples shown and discussed here, any specific value should be interpreted as being merely exemplary, rather than as a limitation. Therefore, other examples of exemplary embodiments may also include different values. It should be noted that similar reference numerals and letters represent similar items in the following drawings, so that once a certain item is defined in an accompanying drawing, it does not need to be further discussed in subsequent drawings.

[0025] like Figure 1 As shown, a prefabricated enclosure and ring beam joint structure and treatment method include a building moisture-proof layer 1, a metal flashing plate 2, an expansion bolt 3, a first self-tapping screw 4, a second self-tapping screw 5, a prefabricated enclosure 6, and a ring beam 7.

[0026] According to the present invention, referring to Figure 1 It can be seen that first, the building moisture-proof layer 1 is completed on the top of the ring beam 7. There are many methods for building the moisture-proof layer 1. The present invention selects a method of using cement mortar with a thickness of 20 mm and a waterproofing agent with a mass ratio of 1:2. Of course, in actual projects, other methods of moisture-proof layers that can achieve the same effect can also be adopted according to regional habits. The building moisture-proof layer 1 can effectively prevent moisture in the soil below the ground from entering the assembled enclosure 6.

[0027] The metal flashing plate 2 is arranged between the assembled enclosure 6 and the building moisture-proof layer 1. The metal flashing plate 2 is bent downward in a Z shape by 200 mm toward the outdoor end, and its end is fixed in the upper concrete of the ring beam 7 by an expansion bolt 3. The metal flashing plate 2 is bent upward by 200 mm toward the indoor end, and is fixed to the assembled enclosure 6 by a second self-tapping screw 5. All exposed nail heads are coated with neutral silicone sealant. The metal flashing plate 2 is fixed to the building moisture-proof layer 1 by a first self-tapping screw 4 at an appropriate position in the middle.

[0028] The present invention adopts two waterproof measures between the assembled enclosure 6 and the ring beam 7. The metal flashing plate 2 effectively seals the joint between the two, preventing leakage caused by rainwater splashing on the outer wall side, forming the first waterproof measure. The building moisture-proof layer 1 can effectively prevent soil moisture below the ground from penetrating into the assembled enclosure 6 from the bottom, forming the second waterproof measure. The materials used for joint treatment are all common building decoration materials on the market, and are easy to obtain.

[0029] In the description of the present application, it should be understood that the terms "center", "longitudinal", "lateral", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the protection content of the present invention.

[0030] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the present invention. These improvements and modifications should also be regarded as the scope of protection of the present invention.
