[0028] In order to more clearly understand the above-mentioned objects, features and advantages of the present utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, without conflict, the embodiments of the present application and the features in the embodiments can be combined with each other.

[0029] In the following description, many specific details are set forth in order to fully understand the present utility model. However, the present utility model can also be implemented in other ways different from those described herein. Therefore, the present utility model is not limited by the limitations of the specific embodiments disclosed in the following specification.

[0030] As Figure 1-8 shown, the present utility model provides a large-area cement fiber board exterior wall structure based on BIM technology, including an outer wall 1, a connecting plate 2 and a sealing structure.

[0031] On both sides of the back of the outer wall 1, notches 3 are provided, and positioning grooves 4 are provided on the notches 3 at intervals in the vertical direction of the outer wall 1; the connecting plate 2 is arranged in the notch 3 between two adjacent outer walls 1, and a positioning block 5 is integrally formed on the connecting plate 2, and the positioning block 5 can be inserted into the corresponding positioning groove 4; the sealing structure is located between the outer wall 1 and the connecting plate 2 and seals and prevents seepage of the gap between the two.

[0032] In this embodiment, an extrusion groove 6 is provided on the connecting plate 2, and the shape of the cross section of the extrusion groove 6 is similar to the shape of a sunny doll. The sealing structure includes an extrusion rubber strip 7 fixedly connected to the notch 3 on the back of the outer wall 1 and adapted to the shape of the extrusion groove 6. The extrusion rubber strip 7 can be engaged in the extrusion groove 6 and have an interference fit with it; when the connecting plate 2 and the outer wall 1 are docked, the extrusion rubber strip 7 can be squeezed into the extrusion groove 6. Through the shape of the extrusion rubber strip 7 and the interference fit of the extrusion groove 6, the connection plate 2 and the outer wall 1 are waterproof and anti-seepage.

[0033] In this embodiment, the sealing structure also includes a first elastic sealing pad 8 and a second elastic sealing pad 9 which are respectively fixedly connected to the notch 3 on the back side of the outer wall 1 and the side of the connecting plate 2. The first elastic sealing pad 8 and the second elastic sealing pad 9 have opposite sides that are wavy. The first elastic sealing pad 8 and the second elastic sealing pad 9 are staggered and squeezed against each other. When the connecting plate 2 and the outer wall 1 are docked, the second elastic sealing pad 9 on the connecting plate 2 squeezes the first elastic sealing pad 8. Both are elastic and can produce elastic deformation. As the connecting plate 2 is installed, the second elastic sealing pad 9 and the first elastic sealing pad 8 are constantly crossed and after the installation is completed, the two are squeezed and fitted against each other, further playing a waterproof and anti-seepage role between the connecting plate 2 and the outer wall 1.

[0034] In this embodiment, the positioning groove 4 is in the shape of a dovetail groove, and the positioning block 5 is in the shape that matches the positioning groove 4; through the setting of the shapes of the positioning groove 4 and the positioning block 5, the two cooperate with each other more firmly.

[0035] In this embodiment, a stepped circular hole 10 connected to the positioning groove 4 is provided on the outer wall 1, a screw 11 is movably arranged in the stepped circular hole 10, a knob 12 is fixedly arranged at the front end of the screw 11, and a screw hole 13 is provided on the positioning block 5. After the positioning block 5 is inserted into the positioning groove 4, the rear end of the screw 11 can pass through the stepped circular hole 10 and be threadedly connected in the screw hole 13; the screw 11 passes through the stepped circular hole 10 and is screwed into the screw hole 13, thereby realizing the splicing between the outer wall 1 and the connecting plate 2.

[0036] In this embodiment, a hexagonal adjustment hole 14 is provided at the front end of the knob 12, a circular rubber sealing block 15 is inserted into the stepped circular hole 10, and an annular groove 16 is provided on the side of the circular rubber sealing block 15 facing the knob 12, and the outer circle and inner circle of the annular groove 16 are circular and hexagonal respectively; the rotation of the screw 11 can be conveniently controlled through the hexagonal adjustment hole 14 to facilitate installation and disassembly, and the stepped circular hole 10 is sealed by the circular rubber sealing block 15, and the circular rubber sealing block 15 also cooperates with the knob 12 through the annular groove 16, so that the circular rubber sealing block 15 is firmly installed.

[0037] In this embodiment, the notch 3 and the positioning groove 4 on the outer wall 1 are both formed by cutting. The connecting plate 2 is also formed with a positioning block 5 by cutting. After the outer wall 1 and the connecting plate 2 are cut, the cut surfaces are treated with waterproof paint and a two-pass caulking process is adopted to enhance the anti-seepage performance.

[0038] The usage method and working principle of this device: When this device is in use, the installation between the connecting plate 2 and the wall surface is completed in advance. Align the positioning groove 4 on the outer wall 1 with the positioning block 5 on the connecting plate 2, and make the positioning block 5 enter the positioning groove 4 for positioning. Subsequently, pass the screw 11 through the stepped circular hole 10 and adjust and twist it so that the screw 11 is screwed into the screw hole 13 on the positioning block 5 to achieve the splicing between the outer wall 1 and the connecting plate 2. Finally, insert the circular rubber sealing block 15 into the stepped circular hole 10, and the circular rubber sealing block 15 wraps the screwing and the internal hexagonal adjusting hole 14 through the annular groove 16 to block the stepped circular hole 10, making the appearance more beautiful. The above operations are simple and convenient, facilitating the installation of the outer wall 1. And when a certain outer wall 1 is damaged, it can also be replaced separately.

[0039] During the above installation process, as the outer wall 1 gradually fits with the connecting plate 2, during this period, the extrusion rubber strip 7 can be extruded into the extrusion groove 6. Through the interference fit between the shape of the extrusion rubber strip 7 and the extrusion groove 6, it plays a role in waterproofing and anti-seepage between the connecting plate 2 and the outer wall 1. At the same time, a relative displacement occurs between the second elastic sealing pad 9 and the first elastic sealing pad 8. Both of them are elastic and can produce elastic deformation and squeeze each other. The second elastic sealing pad 9 and the first elastic sealing pad 8 cross continuously and squeeze and fit with each other after the installation is completed, further playing a role in waterproofing and anti-seepage between the connecting plate 2 and the outer wall 1, so that after the installation, there is good waterproofing and anti-seepage ability between adjacent two outer walls 1 and between the outer wall 1 and the connecting plate 2, and the waterproofing and anti-seepage performance is guaranteed.

[0040] The above is only a preferred embodiment of the present invention, and it is not a limitation to the present invention in other forms. Any person skilled in the art may use the disclosed technical content to make changes or modifications into equivalent change equivalent embodiments and apply them to other fields. However, as long as it does not depart from the technical solution content of the present invention, any simple modification, equivalent change and modification made to the above embodiments according to the technical essence of the present invention still belong to the protection scope of the technical solution of the present invention.
