[0025] See also Figure 1 to Figure 2 As shown, according to an embodiment of the present application, a rammed earth wall is provided, comprising an installation base, a partition wall layer 2 and a rammed earth layer 7, the installation base having a first surface and a second surface arranged opposite to each other, the partition wall layer 2 being arranged on the first surface, and a partition strip being installed on the side of the partition wall layer 2 away from the installation base to form a plurality of rammed earth stacking areas, and the rammed earth layer 7 is arranged in the plurality of rammed earth stacking areas.

[0026] The rammed earth wall provided in the embodiment of the utility model installs partition strips on the partition wall layer 2 so that the space on the partition wall layer 2 can be divided into a number of independent rammed earth stacking areas, so that the shrinkage deformation between the rammed earth walls in each rammed earth stacking area does not affect each other, which can reduce the cracks caused by the mutual influence of shrinkage deformation, and can effectively resist the shrinkage deformation of the rammed earth wall and reduce the generation of cracks; at the same time, the rammed earth walls in the rammed earth stacking area are tied together by the partition strips to form a whole, which can form a constraint on the rammed earth wall to improve the horizontal shear resistance and crack resistance of the rammed earth wall, thereby improving the durability of the rammed earth wall and the safety under earthquake action.

[0027] Among them, in the embodiment of the present application, the supporting foundation 1 is a keel frame, and the keel height and shape can be customized by the factory according to the design and assembled on site to ensure installation accuracy, speed up construction period, and improve efficiency.

[0028] The keel frame includes a plurality of vertical keels and a plurality of transverse keels. The vertical keel can be a vertical I-beam, and the width of the vertical keel should be the same as the height of the rammed earth wall. The transverse keel can be a transverse channel steel, and the width of the vertical keel is the same as the width of the rammed earth wall.

[0029] Specifically, the transverse keel and the vertical keel can be welded or fixed by bolts to connect the transverse keel and the vertical keel. In the embodiment of the present application, the transverse keel and the vertical keel are connected by three-sided full welding, and the weld angle height can be 3-4mm; the vertical keel and the transverse keel are connected by two-sided full welding.

[0030] Among them, several vertical keels are arranged parallel to each other, and several horizontal keels are also arranged parallel to each other, so that the frame-shaped space formed by the several vertical keels and the several horizontal keels are connected to form a rectangular shape with a regular shape, which is easy to construct. Of course, the horizontal keels can also be arranged at an angle, and the frame-shaped space formed is irregular in shape, which can enhance the design effect of the rammed earth wall facade and have a better sense of design.

[0031] Among them, heat-insulating materials 8 are arranged in a plurality of frame-shaped spaces.

[0032] The insulation material 8 may be an insulation decorative board, and the bulk density of the insulation material 8 meets 140KG / m 3 That is, the present application does not make any further limitation. In the embodiment of the present application, the thermal insulation material 8 is a rock wool board.

[0033] Specifically, the insulation material 8 is filled in several frame-shaped spaces of the keel frame. In the embodiment of the present application, both sides of the keel frame are sealed, and the insulation material 8 is filled after the lining plate on one side is installed. By filling the insulation material 8 in the frame-shaped space, the rammed earth wall has heat insulation and sound insulation properties; at the same time, it can meet energy-saving requirements and improve energy utilization.

[0034] The keel frame includes a first surface and a second surface arranged opposite to each other, the first surface is the outer side of the keel frame, and the second surface is the inner side of the keel frame. In the embodiment of the present application, a partition wall layer 2 is arranged on both the inner and outer sides of the keel frame.

[0035] Specifically, the partition wall layer 2 may be a cover plate of the keel frame, used to hide and protect the pipes and related auxiliary equipment embedded in the keel frame, so as to integrate the enclosure, decoration, heat preservation and sound insulation of the wall.

[0036] Wherein, a partition bar is installed on the outer partition wall layer 2 of the supporting foundation 1, and the partition bar can be a metal purlin or the like.

[0037] Among them, several separators can be provided.

[0038] Specifically, in the embodiment of the present application, some of the dividing strips are arranged horizontally, and other parts of the dividing strips are arranged vertically. By installing a plurality of dividing strips on the partition wall layer 2, the space on the partition wall layer 2 can be divided into a plurality of independent rammed earth masonry areas, so that the shrinkage deformation of the rammed earth walls in each rammed earth masonry area does not affect each other, which can reduce the cracks caused by the mutual influence of the shrinkage deformation, and can effectively resist the shrinkage deformation of the rammed earth wall and reduce the occurrence of cracks; at the same time, the rammed earth walls in each rammed earth masonry area are tied together by the dividing strips to form a whole, which can form a constraint on the rammed earth wall to improve the horizontal shear resistance and crack resistance of the rammed earth wall, thereby improving the durability of the rammed earth wall and the safety under the action of earthquakes.

[0039] Among them, by setting up dividing strips, the construction sections can be divided into compartments for construction, which is convenient for making construction plans and thus can improve construction efficiency.

[0040] The rammed earth wall further comprises a rammed earth layer 7. The rammed earth layer 7 can be formed by ramming raw soil layer by layer. The rammed earth layer 7 has a compact and hard structure and can be used as a wall.

[0041] The rammed earth layer 7 is arranged in a plurality of rammed earth stacking areas and is tied together by a plurality of partition strips.

[0042] Specifically, the rammed earth wall provided in the embodiment of the present application can be applied to the building facades and interior decoration of new construction projects and urban renewal projects. For example, the rammed earth wall can be applied to the indoor and outdoor decoration projects of theme parks, the indoor and outdoor decoration projects of museum exhibition halls, or the facade restoration projects of ancient buildings, etc., and the present application does not make further limitations. It can be understood that by arranging the rammed earth layer 7 on the outer surface of the wall, using its natural loess color, the entire building is closer to nature; at the same time, the rammed earth wall can be constructed by taking materials nearby, and after demolition and reconstruction, the soil can be reused, thereby reducing the construction cost and having good economic benefits.

[0043] In some possible implementations provided by the present disclosure, see Figure 1-2 As shown, the rammed earth wall further includes an anti-cracking layer 6 , which is arranged between the partition wall layer 2 and the rammed earth layer 7 , and the anti-cracking layer 6 is located in an area outside the projection of the partition strip on the partition wall layer 2 .

[0044] By providing the anti-cracking layer 6 in the area outside the projection of the partition strip on the partition wall layer 2, the rammed earth layer 7 applied subsequently can be effectively prevented from cracking, so as to improve the horizontal shear resistance and anti-cracking capacity of the rammed earth wall.

[0045] The anti-cracking layer 6 may be a product of hardened anti-cracking mortar.

[0046] Specifically, the anti-crack layer 6 can be used as the base layer of the rammed earth layer 7. The anti-crack mortar can be evenly applied to the area outside the projection of the partition strip on the partition wall layer 2 by a rolling brush, and then the anti-crack mortar is roughened horizontally and deeply with a special hard brush. After the roughening is completed, it is left to stand for more than 15 days, and after solidification, the anti-crack layer 6 is formed. By roughening the anti-crack mortar horizontally, the tensile strength along the grain of the rammed earth wall can be improved, thereby effectively suppressing the generation of oblique cracks in the wall under the action of horizontal shear force, thereby improving the durability of the wall.

[0047] In some possible implementations provided by the present disclosure, see Figure 1-2 As shown, the partition wall layer 2 includes a base layer 21 and a surface layer 22 , and the surface layer 22 is arranged on a side of the base layer 21 away from the supporting foundation 1 .

[0048] The partition wall layer 2 includes a base layer 21 and a surface layer 22, that is, the partition wall layer 2 includes two layers, the inner layer is the base layer 21, and the outer layer is the surface layer 22. By setting the partition wall layer 2 to include the base layer 21 and the surface layer 22, the thermal insulation and sound insulation performance of the rammed earth wall can be further improved, and the user experience can be improved; at the same time, it can meet energy-saving requirements and improve energy utilization.

[0049] In some possible implementations provided by the present disclosure, see Figure 1 As shown, the base layer 21 includes a plurality of first cement boards, the surface layer 22 includes a plurality of second cement boards, and the plurality of first cement boards and the plurality of second cement boards are staggered in a first direction.

[0050] The first cement board and the second cement board may be ordinary cement boards or fiber cement boards, etc. In the embodiment of the present application, the first cement board and the second cement board are medium-density cement boards.

[0051] Specifically, the first cement board is fixedly arranged on the keel frame, the second cement board is arranged on the side of the first cement board away from the keel frame and is fixedly connected to the keel frame, and the first cement board and the second cement board can be fixed to the keel frame by self-tapping screws. During construction, the screws are not less than 10mm from the edge of the cement board, and not less than 15mm from the cut edge, and the nuts are slightly embedded in the board.

[0052] Among them, a plurality of first cement boards and a plurality of second cement boards are staggered in the first direction.

[0053] Specifically, the first direction can be a direction perpendicular to the supporting foundation 1 in a horizontal plane. By arranging a plurality of first cement boards and a plurality of second cement boards in a staggered manner along a direction perpendicular to the keel frame, cracking of the rammed earth stacked on the partition wall layer 2 can be avoided, thereby improving the durability of the rammed earth wall and its safety under earthquake action.

[0054] In some possible embodiments provided by the present disclosure, the distance between the projection of the lap joint of the first cement board on the surface layer 22 and the lap joint of the second cement board is A, and A≥600 mm.

[0055] The overlapping seams between the first cement boards may be 5 mm; the overlapping seams between the second cement boards may also be 5 mm.

[0056] Specifically, the first cement board and the second cement board are staggered by at least 600 mm.

[0057] In some possible implementations provided by the present disclosure, see Figure 1-2 As shown, a plurality of dividing strips are provided, including a first dividing strip 4 and a second dividing strip 5 , a plurality of expansion joints 3 are provided on the supporting base 1 , a first dividing strip 4 is provided on both sides of the expansion joint 3 , and a second dividing strip 5 is provided between two adjacent expansion joints 3 .

[0058] The expansion joint 3 may be an expansion joint 3 of the keel frame. In the embodiment of the present application, the expansion joint 3 is a flat joint. The expansion joint 3 is used to prevent the keel frame from being damaged due to climate temperature changes (thermal expansion and contraction). Several expansion joints 3 may be provided to divide the keel frame into several independent parts so that the keel frame can be horizontally expanded and contracted.

[0059] The expansion joint 3 is a gap reserved before the keel frame is assembled. The width of the expansion joint 3 may be 3-5 mm, and the distance between two adjacent expansion joints 3 may be 12 m.

[0060] It is understandable that when the partition wall layer 2 is fixedly installed on the keel frame, the expansion joint 3 also penetrates the partition wall layer 2 at the same time. After the partition wall layer 2 is fixed, the expansion joint 3 is filled with elastic foam to avoid the formation of cold bridges.

[0061] The first dividing strip 4 may be an angle iron or the like.

[0062] Among them, two first dividing strips 4 form a group. In the embodiment of the present application, there are several groups of first dividing strips 4, and the several groups of first dividing strips 4 are arranged in a one-to-one correspondence with the several expansion joints 3.

[0063] For details, see Figure 1 As shown, the first dividing strip 4 is fixedly connected to the partition wall layer 2, and the first dividing strip 4 is arranged on the side of the partition wall layer 2 away from the keel frame. In the implementation of the present application, two first dividing strips 4 in the same group are arranged opposite to each other along the width direction of the expansion joint 3, and the distance between the two first dividing strips 4 is the same as the width of the expansion joint 3. It can be understood that the first dividing strip 4 can trim the expansion joint 3, and can also divide the space of the partition wall layer 22 into a plurality of independent rammed earth stacking areas while supporting the raw soil of the rammed earth stacking areas.

[0064] The second dividing strip 5 may also be an angle iron or the like.

[0065] For details, see Figure 2 As shown, the second dividing strip 5 is fixedly connected to the partition wall layer 2, and the second dividing strip 5 is arranged on the side of the partition wall layer 2 away from the keel frame. In the embodiment of the present application, the second dividing strip 5 is arranged between two adjacent expansion joints 3 and is located in the same plane as the first dividing strip 4. The distance between two adjacent second dividing strips 5 can be 12m. By arranging the second dividing strip 5, the space on the partition wall layer 2 can be divided into a number of independent rammed earth masonry areas, and the second dividing strip 5 combined with the first dividing strip 4 can support the raw soil of each rammed earth masonry area and connect each rammed earth masonry area into a whole.

[0066] In some possible embodiments provided by the present disclosure, the rammed earth wall further includes a waterproof layer, a mesh cloth is arranged inside the waterproof layer, and the waterproof layer is arranged between the partition layer 2 and the anti-cracking layer 6.

[0067] The provision of a waterproof layer can prevent the rammed earth wall from leaking rain, and at the same time, can prevent the thermal insulation material 8 in the rammed earth wall from failing, thereby improving the thermal insulation performance of the rammed earth wall.

[0068] The waterproof layer may be a product obtained by hardening the polymer waterproof mortar.

[0069] Among them, the thickness of the waterproof layer can be 4mm.

[0070] The waterproof layer is arranged between the partition wall layer 2 and the anti-cracking layer 6 , and both the waterproof layer and the anti-cracking layer 6 are the base layers of the rammed earth layer 7 .

[0071] Specifically, the waterproof layer is constructed before the anti-cracking layer 6, and the polymer waterproof mortar can be applied to the area outside the projection of the first dividing strip 4 and the second dividing strip 5 on the partition wall layer 2 by a roller brush, and the waterproof layer is formed after curing.

[0072] Among them, a mesh cloth is arranged inside the waterproof layer. Specifically, a layer of mesh cloth can be laid on the evenly applied polymer waterproof mortar by pressing and compacting it flat.

[0073] It is understandable that the waterproof layer is the basis for subsequent construction. Therefore, by lining the waterproof layer with mesh cloth, the rammed earth layer 7 applied subsequently can be prevented from cracking, so as to improve the horizontal shear resistance and crack resistance of the rammed earth wall.

[0074] In some possible embodiments provided by the present disclosure, the rammed earth layer 7 includes a first raw soil layer and a second raw soil layer, and the second raw soil layer is arranged on a side of the first raw soil layer away from the supporting foundation 1 .

[0075] The rammed earth layer 7 includes a first raw soil layer and a second raw soil layer, so that the rammed earth layer 7 can be constructed in sections while meeting the thickness requirement of the rammed earth wall, which is convenient for making a construction plan and thus can improve the construction efficiency.

[0076] Among them, the first raw soil layer is arranged on the surface of the anti-cracking layer 6, and the raw soil can be applied to the anti-cracking layer 6 by a roller brush and compacted with force, and the whole is scraped flat and then dried for 1-2 days to form the first raw soil layer.

[0077] Among them, the thickness of the first raw soil layer can be 8mm.

[0078] Wherein, a glass fiber mesh cloth is arranged in the first raw soil layer, and the specification of the glass fiber mesh cloth may be 160g.

[0079] Specifically, after the first layer of raw soil is applied, a glass fiber mesh cloth can be laid on the first raw soil layer by pressing and compacting it to make it flat. By lining the first raw soil layer with the glass fiber mesh cloth, cracking of the first raw soil layer can be avoided, thereby improving the horizontal shear resistance and crack resistance of the rammed earth wall.

[0080] Among them, the second raw soil layer is arranged on the surface of the first raw soil layer, and the construction method of the second raw soil layer is the same as that of the first raw soil layer, which will not be repeated here.

[0081] Among them, the thickness of the second soil layer can be 7mm.

[0082] Specifically, in the embodiment of the present application, the thickness of the rammed earth layer 7 is only 15 mm, which can restore the appearance of the traditional rammed earth wall and maintain its effect of being warm in winter and cool in summer, thereby improving the user experience.

[0083] It is understandable that the thickness of traditional rammed earth walls must reach 600-1000mm to achieve the physical properties of being warm in winter and cool in summer. The construction cost is high and the consumption of yellow mud is large. The thickness of the rammed earth wall provided by the implementation of this application is only 15mm, and materials can be obtained nearby, which reduces construction costs. After dismantling, the keel and soil can be reused. The old yellow mud can absorb nitrogen in the air and return to the land as fertilizer after dismantling and crushing.

[0084] In some possible embodiments provided by the present disclosure, the rammed earth wall further includes a paint layer, and the paint layer is disposed on a side of the rammed earth layer 7 facing away from the supporting foundation 1 .

[0085] Wherein, the coating layer can be a surface protective agent layer.

[0086] Specifically, after the rammed earth layer 7 is cured and dried, a finishing protective agent is sprayed on the surface of the rammed earth layer 7 to protect the finishing surface.

[0087] The rammed earth wall provided in the embodiment of the utility model installs partition strips on the partition wall layer 2 so that the space on the partition wall layer 2 can be divided into a number of independent rammed earth stacking areas, so that the shrinkage deformation between the rammed earth walls in each rammed earth stacking area does not affect each other, which can reduce the cracks caused by the mutual influence of shrinkage deformation, and can effectively resist the shrinkage deformation of the rammed earth wall and reduce the generation of cracks; at the same time, the rammed earth walls in the rammed earth stacking area are tied together by the partition strips to form a whole, which can form a constraint on the rammed earth wall to improve the horizontal shear resistance and crack resistance of the rammed earth wall, thereby improving the durability of the rammed earth wall and the safety under earthquake action.

[0088] It is easy for those skilled in the art to understand that, under the premise of no conflict, the above-mentioned advantageous methods can be freely combined and superimposed.

[0089] The above are only preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application. The above are only preferred implementations of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and variations can be made without departing from the technical principles of the present application, and these improvements and variations should also be regarded as the protection scope of the present application.
