Traditional rammed earth walls are mostly single-wall structures, which only have simple ornamental functions and do not have waterproof, heat-insulating and other functions. In the Chinese utility model patent with patent number CN202320120529.1, entitled Rammed Earth Wall Structure with Waterproof and Heat-Insulating Functions, a thermal insulation and waterproof wall body is provided, which is combined with the traditional rammed earth wall body. The composite rammed earth wall structure not only ensures the beauty and ornamental properties of the rammed earth wall, but also improves the waterproof and heat-insulating functions of the rammed earth wall structure through the thermal insulation and waterproof wall body, thereby avoiding the occurrence of indoor wall paint being damp and moldy, and can be used to maintain the exterior wall. However, the thermal insulation and waterproof wall body is tightly fitted to the rammed earth wall, resulting in water vapor on the rammed earth wall penetrating into the thermal insulation and waterproof wall body. At the same time, the thermal insulation and waterproof wall body does not have a drainage function, resulting in excessive indoor humidity. Utility Model Content

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] refer to Figure 1-2 As shown, the rammed earth wall structure with both waterproof and heat-insulating functions provided by the utility model includes: a rammed earth wall 1, a thermal insulation cotton layer 3 and an inner wall 4 installed in sequence from the outside to the inside, the thermal insulation cotton layer 3 is adhesively installed on the rammed earth wall 1, and a plurality of connecting mechanisms are installed between the thermal insulation cotton layer 3 and the inner wall 4, and a waterproof gap for waterproofing is formed between the thermal insulation cotton layer 3 and the inner wall 4 through the plurality of connecting mechanisms.

[0026] As mentioned above, when using the rammed earth wall 1, insulation cotton layer 3 and inner wall 4 provided by the utility model, the insulation cotton layer 3 is adhered to the rammed earth wall 1 by structural adhesive, and the inner wall 4 is installed at intervals on the outside of the insulation cotton layer 3 by multiple connecting mechanisms to avoid direct contact between the inner wall 4 and the insulation cotton layer 3.

[0027] In the present utility model, combined with Figure 3 As shown, a plurality of longitudinally distributed water guide grooves 2 are provided at equal distances from left to right on the rammed earth wall 1 of this embodiment, and the plurality of water guide grooves 2 are used to guide out the water vapor between the rammed earth wall 1 and the thermal insulation cotton layer 3 .

[0028] As mentioned above, when using the multiple water guide grooves 2 provided by the utility model, the multiple water guide grooves facilitate the liquid on the rammed earth wall 1 to be gathered downward by gravity.

[0029] Further, in order to discharge the collected liquid, refer to Figure 1-3 As shown, a collecting trough 9 extending to the outside is provided between the bottoms of the plurality of water guide grooves 2, and the collecting trough 9 is arranged below the waterproof gap. The collecting trough 9 facilitates the liquid collected at the bottoms of the plurality of water guide grooves 2 to be discharged outwards.

[0030] In the present utility model, combined with Figure 1-2 and Figure 4 As shown, the connection mechanism of this embodiment includes a screw rod 8, a screw sleeve 7 and a mounting frame. A plurality of mounting holes 14 are provided in a rectangular array on the rammed earth wall 1. One ends of the plurality of screw rods 8 are respectively screwed in the corresponding mounting holes 14. One ends of the plurality of screw sleeves 7 are rotatably mounted on the mounting frame. A threaded hole 11 is provided at one end of the screw sleeve 7 close to the screw rod 8. One end of the screw rod 8 facing away from the rammed earth wall 1 passes through the thermal insulation cotton layer 3 and is screwed in the corresponding threaded hole 11. The inner wall 4 is adhered to the side of the mounting frame facing away from the screw sleeve 7.

[0031] As mentioned above, when using the connecting mechanism provided by the utility model, one end of the screw 8 in the connecting mechanism is installed on the rammed earth wall 1 through the mounting hole 14, and the screw sleeve 7 provides an installation position for the inner wall 4 to be installed on the screw 8 on the outer side of the thermal insulation cotton layer 3. By rotating the screw sleeve 7 on the screw 8, the overall length of the screw 8 and the screw sleeve 7 can be adjusted, and then the distance between the thermal insulation cotton layer 3 and the inner wall 4 can be adjusted.

[0032] Further, in order to install the inner wall 4 on multiple connection mechanisms, refer to Figure 1-2 As shown in FIG. 5 , the mounting frame is a rectangular frame 10, and a plurality of beams are installed at equal distances on the inner side of the frame 10, and one end of a plurality of screw sleeves 7 is rotatably mounted on the corresponding beams. The plurality of beams on the frame 10 provide mounting positions for the plurality of screw sleeves 7, and the frame 10 provides mounting positions for the inner wall 4 on the plurality of screw sleeves 7.

[0033] Further, in order to allow the screw sleeve 7 to rotate on the screw rod 8, refer to Figure 4-6As shown, mounting seats 5 are evenly installed on multiple beams, a ball block 12 is installed at one end of each mounting seat 5, a ball seat 6 that can rotate on the corresponding ball block 12 is installed at one end of each screw sleeve 7, and each ball seat 6 is installed with a limiter extending to the ball block 12, and the limiter is used to limit the rotation of the ball seat 6. The ball block 12 is installed on the frame 10 through the mounting seat 5, and the screw sleeve 7 is rotatably installed on the ball block 12 through the ball seat 6. When the ball seat 6 rotates on the ball block 12, the screw sleeve 7 can be driven to move on the screw rod 8, so that the distance between the thermal insulation cotton layer 3 and the inner wall 4 can be adjusted. When the distance does not need to be adjusted, the ball seat 6 is limited to the ball block 12 through the limiter, so that the ball seat 6 cannot rotate on the ball block 12.

[0034] Further, in order to avoid the ball block 12 being universally adjusted in the ball seat 6, refer to Figure 6 As shown, the stopper includes a fastening bolt 15, which is screwed on the ball seat 6, and one end of the fastening bolt 15 abuts against the ball block 12. When the ball seat 6 is not required to rotate on the ball block 12, the fastening bolt 15 is tightened to allow one end of the fastening bolt 15 to abut against the ball block 12, and the ball seat 6 cannot be universally adjusted on the ball block 12.

[0035] Further, in order to allow the ball seat 6 to rotate on the ball block 12, refer to Figure 4 As shown, a ball groove 13 is formed at one end of the ball seat 6, and the ball block 12 is hinged in the ball groove 13. The ball groove 13 provides a universally rotatable mounting position for the ball block 12 on the ball seat 6. When the mounting seat 5 rotates on the ball block 12, the screw sleeve 7 can rotate on the screw rod 8, so that the distance between the thermal insulation cotton layer 3 and the inner wall 4 can be adjusted.
