[0022] In order to more clearly illustrate the embodiments of the utility model or the technical solutions in the prior art, the specific implementation methods of the utility model will be described below with reference to the accompanying drawings. Obviously, the drawings described below are only some embodiments of the utility model. For ordinary technicians in this field, they can also be understood as further technical solutions without paying creative work. In some figures, components with the same structure or function are only schematically illustrated, or only one of them is marked. In this article, "one" not only means "only one", but also means "more than one", and "several" includes "two" and "more than two".

[0023] In this article, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0024] In addition, in the description of the present application, the terms "first", "second", etc. are only used to distinguish the description and cannot be understood as indicating or implying relative importance.

[0025] Example 1, with reference to Figure 1~Figure 4 A waterproof lap strip for expansion joints is proposed, comprising: a first waterproof body 1 having a flat surface on one side close to the installation wall or the ground; a plurality of bosses 110 arranged at intervals on the side away from the wall or the ground, and the first waterproof body 1 having a boss 110 on the side away from the wall or the ground, and the boss 110 is arc-shaped.

[0026] In this embodiment, the first waterproof body 1 is the main waterproof structure, which can be made of various materials such as PC, PE, TPE, PVE, rubber, polymer materials, etc. When in use, the flat side is directly attached to the gap that may leak. Since this side is flat, it can be better combined with the wall. At the same time, the overall thickness of the first waterproof tape is very thin. After being attached to the wall, the gap between the wall and the first waterproof tape is more difficult to penetrate, ensuring the waterproof performance. At the same time, the boss 110 is arc-shaped, and the middle part is thicker than the two sides, so that the first waterproof body 1 is placed naturally on both sides close to the wall, which improves the waterproof form and quality of the first waterproof body 1 and further improves the waterproof effect.

[0027] As a further technical solution, the first waterproof body 1 is flexible.

[0028] In this embodiment, since the first waterproof body 1 is thin and made of PC, PE, TPE, PVE, rubber, etc., the first waterproof body 1 is soft. The soft first waterproof body 1 can ensure that the lap joint adapts to wall seams of different shapes, improve the adaptability of the waterproof belt, and ensure complete fit even in complex-shaped construction sites, thereby improving the performance of the waterproof belt. At the same time, the first waterproof body 1 further reduces the possibility of infiltration and improves the stability of the device.

[0029] As a further technical solution, it also includes: a first adhesive film 2 is arranged on the side of the first waterproof body 1 away from the installation wall or the ground, and the surface of the first adhesive film 2 is rough; there are several second adhesive films 3, and the second adhesive films 3 are arranged on the side of the first waterproof body 1 close to the wall or the ground. The first adhesive film 2 and the second adhesive film 3 are bonded and connected, the second adhesive film 3 is used to bond with the ground or wall, and the first adhesive film is used to connect with other materials.

[0030] In this embodiment, the first adhesive film 2 is adhered to the side of the first waterproof body 1 that is not close to the wall. When the waterproof tape is installed on the wall, the rougher side will be exposed to the outside, thereby simplifying the subsequent application of waterproof coatings and improving the adhesion between the waterproof coatings and the waterproof tape. At the same time, the use of overlapping tapes for waterproofing can also ensure that the wall seams are more beautiful and smoother, thereby improving the user experience after the decoration is completed. Moreover, the first adhesive film 2 is also made of a water-proof material, and the rough surface enables it to be better applied and adhered to the waterproof coating, thereby improving the adhesion of the waterproof coating and improving the waterproof performance.

[0031] In this embodiment, the second adhesive film 3 and the first adhesive film 2 have similar functions. The second adhesive film 3 is mainly used to cooperate with the waterproof coating to well adhere the second adhesive film 3 and the inner surface of the first waterproof body 1 to the wall to prevent the second waterproof body from separating from the wall. Multiple second adhesive films 3 are respectively arranged on both sides of the first waterproof body 1, and do not completely cover the side of the first waterproof body 1 close to the wall. When in use, the second adhesive film 3 can not only strengthen the connection with the first waterproof body 1, but also ensure that the smooth surface of the first waterproof body 1 is always close to the wall, thereby ensuring the waterproof performance.

[0032] refer to Figure 3 This is Example 2 of the present utility model. Based on Example 1, a through hole 4 is provided in the center of the first body and the first adhesive film 2 .

[0033] In this embodiment, the first main body and the first adhesive film 2 are used to be installed at locations on the ground where holes are required, such as drainage holes or power holes in bathrooms for waterproofing; the through holes 4 have different sizes, and different sizes are used to adapt to different hole sizes. This shape of hole is specifically used to adapt to the waterproof sealing of drainage holes on the ground, thereby improving the waterproof effect of these places.

[0034] refer to Figure 4 This is the third embodiment of the utility model. Based on the embodiment 1, it further includes: the first waterproof body 1, the first adhesive film 2 and the second adhesive film 3 all have a bending portion 5, and the shape of the bending portion 5 is the same as that of a wall corner.

[0035] In this embodiment, the lap strip with the bending portion 5 is used to seal the corner of the wall to prevent water seepage and leakage at the corner of the wall, thereby improving the waterproof performance of the corner. Moreover, the bending portion 5 is integrally formed without gaps for water leakage, thereby further improving the waterproof performance.

[0036] It should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the spirit and scope of the technical solution of the utility model, which should be included in the scope of the claims of the utility model.
