Detailed Description

As shown in fig. 1 to 4, the present utility model provides a building board having a waterproof function, comprising: the waterproof layer 3 covers the middle plate 2, the edge of the waterproof layer 3 is also provided with an extending turnover part 31, and the extending turnover part 31 is arranged on the outer side of the middle plate 2 and is abutted against the side wall of the middle plate 2; the extended turnover 31 is configured such that two extended turnover 31 disposed opposite to each other after the two building boards having the waterproof function are spliced together are connected together and form the overlapping portion 300.

Specifically, the building board with the waterproof function of the present embodiment has a plate-like structure as a whole, and one surface of the intermediate plate 2 is protected by the outer plate body 1, and the outer plate body 1 may be formed by processing a harder material, for example: the outer panel 1 can effectively improve the overall structural strength of the building board having a waterproof function without limitation. In order to meet the requirement of the building board with waterproof function on waterproof performance, a waterproof layer 3 is arranged on the other surface of the middle board 2, and the waterproof layer 3 can be made of conventional waterproof coiled materials and other materials, and can be bonded or directly formed on the middle board 2.

In order to extend the waterproof service life of the building board having the waterproof function, the connection manner of the waterproof layers of two adjacent building boards having the waterproof function is improved, that is, the waterproof layer 3 has an extending turnover portion 31 arranged outside the intermediate plate 2, taking the posture of the building board having the waterproof function in fig. 1 as an example, the waterproof layer 3 is arranged on a horizontal plane, and the extending turnover portion 31 is arranged vertically as a whole. Referring to fig. 2, it can be seen that, during construction in the field, the edges of two adjacent building boards with waterproof function are butted together, so that two oppositely disposed extending turnover parts 31 can be abutted against each other to form an overlapping part 300, and the overlapping part 300 is also in an upright state as a whole.

In the later use process, the overlapping part 300 is in a standing state relative to the waterproof layer formed between the waterproof layer 3 and the building, and the connecting area formed by the two extending turnover parts 31 in the overlapping part 300 is arranged in a vertical plane, so that the waterproof and infiltration functions are better. More importantly, in the case that the waterproof layer 3 is shrunk due to the decrease of the external temperature in the later long-term use process, since the two extending turnover parts 31 in the overlapped part 300 are arranged in a vertical plane relative to the main body of the waterproof layer 3, when the tensile force generated by the shrinkage of the waterproof layer 3 reaches a certain value, the root of the overlapped part 300 will crack by a certain amount, and further, the extending turnover part 31 which cracks at the root of the overlapped part 300 is further utilized to generate a proper amount of deformation so as to meet the deformation amount required by the shrinkage of the whole waterproof layer 3 (refer to the separation of the two extending turnover parts 31 in the root area of the overlapped part 300 in fig. 4). Therefore, the problem that the lap joint part is broken easily caused by direct lap joint of the waterproof coiled material along the surface needing waterproof treatment in the prior art can be solved, and the waterproof service life and the use reliability of the building board with the waterproof function are effectively prolonged.

Wherein, for convenience of processing and manufacturing, the overlapping portion 300 is perpendicular to the waterproof surface formed by the waterproof layer 3. And for the use, the overlapped part 300 formed by the two opposite extending turnover parts can be pulled apart when the waterproof layers 3 on the two sides shrink.

In addition, the specific connection manner of the two extending turnover portions 31 may be adhesive or may be a connection manner such as heating and melting, which is not limited and described in detail herein. The length of the two extending turnover parts 31 can be between 2CM and 10CM, so that the requirement of firm bonding of the two extending turnover parts 31 and the requirement of water resistance are met.

Further, the intermediate plate 2 is a deformable plate material. Specifically, since the building board itself having the waterproof function has the waterproof capability, in order to enable the waterproof layer 3 to be more closely attached to the surface of the building during the construction process, a deformable board is used as the intermediate board 2. Thus, in the construction process, when uneven surface parts of a building exist, constructors press the building board with the waterproof function to enable the middle plate 2 to be stressed to generate a certain deformation, and then the waterproof layer 3 can be closely attached to the surface of the building. The material of the middle plate 2 may be a conventional plate such as a foam plate, which is not limited and described herein.

Still further, as shown in fig. 5, in order to facilitate rapid splicing of building boards with waterproof function on site, two side portions of the outer board 1 or the middle board 2 are provided with connection portions 21, and the remaining two side portions of the outer board 1 or the middle board 2 are provided with connection mating portions 22; after the two building boards with waterproof function are spliced together, the connecting part 21 is connected with the oppositely arranged connecting matching part 22.

Specifically, during construction, two adjacent building boards with waterproof functions are mutually matched with the connecting matching part 22 through the connecting part 21 so as to be connected together quickly and reliably, thereby facilitating site construction and shortening the construction period.

The concrete entity of the connecting portion 21 and the connecting mating portion 22 may have various structural forms. For example, the connection portion 21 is a plugging protrusion, and the connection mating portion 22 is a plugging groove; alternatively, the connection portion 21 is a lap joint portion, and the connection mating portion 22 is a lap joint mating portion.

Still further, in order to better enhance the waterproof performance of the overlapping portion 300 formed by the extending turnover portion 31, the extending turnover portion 31 completely or partially covers the connection portion 21 and the connection mating portion 22.

Specifically, after two building boards with waterproof function are spliced together through the connecting portion 21 and the connecting matching portion 22, on one hand, the two extending turnover portions 31 which are oppositely arranged are mutually attached and connected to form the overlapping portion, and on the other hand, the overlapping portion is extruded between the connecting portion 21 and the connecting matching portion 22, so that the mechanical connection of the two extending turnover portions 31 through the connecting portion 21 and the connecting matching portion 22 is realized, and the connection tightness of the two extending turnover portions is further improved.

Correspondingly, the overlapping portion 300 further forms a bending structure (not shown) between the connecting portion 21 and the connection mating portion 22, and the bending structure can further improve the waterproof capability of the overlapping portion 300.

In addition, the utility model also provides a building waterproof system, which comprises a building, wherein a surface to be protected is formed on the building, and a plurality of building boards with waterproof functions are also included; the building boards with the waterproof function are arranged on the surface to be protected and spliced together, and two water flow channels opposite to each other in two adjacent building boards with the waterproof function are mutually communicated.

The foregoing is merely illustrative of the present utility model, and the present utility model is not limited thereto, and any changes or substitutions easily contemplated by those skilled in the art within the scope of the present utility model should be included in the scope of the present utility model. Therefore, the protection scope of the utility model is subject to the protection scope of the claims.
