Description

Technical Field

[0001] The present invention relates to the field of surface material paving, and in particular to an aerated concrete wall surface material paving structure. Background Art

[0002] With the improvement of construction technology, most of the walls in the interior of the building are built with aerated concrete that does not provide support. However, when aerated concrete is used as the paving base, the aerated concrete needs to be waterproofed. If waterproofing is not implemented, the plaster layer will be insufficiently hydrated because the internal moisture is absorbed by the aerated concrete base, which will lead to the surface material fixed to the surface of the plaster layer by the adhesive. Because the adhesive cannot effectively bond the inadequately hydrated plaster layer, the fixing effect of the surface material is poor, which eventually causes the surface material to fall off from the plaster layer in the later stage, or the surface material falls off with the fall of the plaster layer. In addition, aerated concrete, as a porous structural material, has a high water absorption capacity. After absorbing water, it has a large volume expansion and its own strength will drop significantly. Due to the unstable foundation and reduced strength, the possibility of hollowing and falling of the finishing layer is further contributed to. Summary of the invention

[0025] The aerated concrete base is a structural base. It can be understood by those skilled in the art that the aerated concrete is a porous material with the characteristics of high water absorption and long water absorption time; and after absorbing water, the moisture can destroy the pore structure of the aerated concrete block, reduce its strength, and make it unable to bear the designed load. Secondly, because the aerated concrete has strong water absorption, when it is immersed in water, it is easy to cause shrinkage and swelling, resulting in cracks, affecting the stability of the entire structure. Therefore, it is particularly important to implement waterproofing treatment on the aerated concrete base.

[0026] In view of the above technical problems, the embodiments of the present disclosure provide a surface material paving structure for an interior wall base, which solves the problem that when the surface material is paved on an aerated concrete base, the aerated concrete base absorbs moisture, resulting in a reduction in strength, which in turn causes the surface material paved on the aerated concrete base to fall off, because the aerated concrete base is not waterproofed.

[0027] Figure 1 The figure shows the overall structure of an aerated concrete wall material paving structure in an embodiment of the present disclosure. Figure 1 In the example, the surface material 70 paving structure of the inner wall base is for paving on the aerated concrete base 10 , and includes a waterproof layer 20 , a first plaster layer 30 , an anti-cracking layer 40 , a second plaster layer 50 , an adhesive layer 60 and the surface material 70 .

[0028] exist Figure 1In the example, the waterproof layer 20 is applied to the aerated concrete base 10. The first plaster layer 30 is laid on the waterproof layer 20. The anti-cracking layer 40 is laid on the first plaster layer 30. The second plaster layer 50 is laid on the first plaster layer 30 to cover the anti-cracking layer 40. The surface material 70 is fixed to the second plaster layer 50 through the adhesive layer 60. The waterproof layer 20 is first applied on the surface of the aerated concrete base 10 to improve the waterproof effect of the aerated concrete base 10. That is, the aerated concrete base 10 can be prevented from absorbing the moisture in the first plaster layer 30 and the second plaster layer 50, and at the same time, it can also be prevented from absorbing the external moisture into the aerated concrete base 10 when the construction period is long, so as to avoid the above-mentioned situation inside the aerated concrete base 10.

[0029] Exemplarily, the waterproof layer 20 is implemented as a waterproof slurry. It is understandable that the waterproof slurry has good permeability and a certain crack resistance, provides waterproof protection for the aerated concrete base layer 10, and prevents the aerated concrete base layer 10 from absorbing water from the first plaster layer 30 and the second plaster layer 50. The benefit of such a setting is not only conducive to the later maintenance of the first plaster layer 30 and the second plaster layer 50, but also avoids the first plaster layer 30 and the second plaster layer 50 from being insufficiently hydrated due to the internal moisture being absorbed by the aerated concrete base layer 10, which in turn causes the surface material 70 fixedly arranged on the surface of the second plaster layer 50 to have a poor fixing effect due to insufficient hydration of the second plaster layer 50, which ultimately causes the surface material 70 to fall off in the later stage, and the first plaster layer 30 and the second plaster layer 50 to crack or fall off.

[0030] Exemplarily, the first plaster layer 30 and the second plaster layer 50 are implemented with polymer mortar. It can be understood by those skilled in the art that the polymer mortar is a crack-resistant mortar with high water retention and high bonding strength, which provides a solid foundation for bonding the surface material 70. Further exemplary, the first plaster layer 30 and the second plaster layer 50 are both implemented as thin layer construction, for example, the thickness of the first plaster layer 30 and the second plaster layer 50 are both 2-3mm. Combined with the overall strength of the polymer mortar, the overall strength of the first plaster layer 30 and the second plaster layer 50 after laying and curing is 6-7Mpa, the strength of the aerated concrete base 10 is 3.5-5Mpa, and the strength of ordinary cement mortar after laying and curing is 10-20Mpa. In comparison, the first plaster layer 30 and the second plaster layer 50 are close to the strength of the aerated concrete base 10, and their elastic modulus and expansion coefficient are close. Therefore, the aerated concrete base layer 10 and the first plaster layer 30 and the second plaster layer 50 have similar expansion and contraction amplitudes when heated and cooled, so as to avoid the stronger one among the aerated concrete base layer 10, the first plaster layer 30 and the second plaster layer 50 from damaging the weaker one.

[0031] Secondly, by constructing the first plaster layer 30 and the second plaster layer 50 in thin layers, the overall thickness of the surface material 70 paving structure of the inner wall base layer can be reduced to increase the usable size indoors, thereby improving the utilization rate of the indoor space.

[0032] Exemplarily, the anti-cracking layer 40 is implemented as a mesh cloth. For example, it is implemented as an acid- and alkali-resistant mesh cloth. Since the polymer mortar is alkaline, the acid- and alkali-resistant mesh cloth can avoid damage due to long-term erosion by the polymer mortar, while improving the strength and crack resistance between the first plaster and the second plaster layer 50, dispersing the shrinkage stress and temperature stress of the surface layer, avoiding stress concentration, and resisting cracking of the surface layer caused by natural temperature and humidity changes and accidental impacts. Exemplarily, the mesh number of the mesh cloth is 50-70 meshes. Of course, it can be understood that the mesh number of the mesh cloth can be adaptively adjusted according to actual needs, and is not limited to this.

[0033] Exemplarily, the surface material 70 is fixed to the second plaster layer 50 through the adhesive layer 60. The adhesive layer 60 is implemented as a polymer-modified cement-based adhesive, which has excellent flexibility and cohesive strength, and can further relax the stress between the second plaster layer 50 and the surface material 70 due to temperature changes, avoid the occurrence of problems such as hollowing and falling of the surface material 70, and improve the reliability of the aerated concrete wall surface material paving structure. Exemplarily, after the back of the larger surface material 70 and the second plaster layer 50 are coated with the adhesive, the surface material 70 is fixed to the second plaster layer 50 through the adhesive layer 60 with the back facing the second plaster layer 50. In another embodiment, the adhesive is first applied to the second plaster layer 50, and then the smaller surface material 70 is fixed to the second plaster layer 50 through the adhesive layer 60 with the back facing the second plaster layer 50. Exemplarily, the thickness of the adhesive layer 60 is 3-8 mm. In this way, the overall thickness of the aerated concrete wall surface material paving structure can be further reduced, thereby improving the utilization rate of indoor space.

[0034] exist Figure 1 In the example, there are multiple surface materials 70, and each adjacent two surface materials 70 form a reserved gap when paving, and the reserved gap is filled with a caulking agent 80. Exemplarily, the size of the reserved gap is 2-3mm. Preferably, the size of the reserved gap is 2.5mm. Exemplarily, the surface material 70 is implemented as a tile or stone. The reserved gap provides a reserved space for the surface material 70 when it expands and contracts due to heat, so as to avoid the adjacent surface materials 70 from being squeezed due to thermal expansion, resulting in the problem of surface material cracking, falling off, etc.; secondly, it can reduce the error when the surface material 70 is paved, avoid uneven tile joints; and provide convenience for the later processing of the reserved gap. The caulking agent 80 can prevent water molecules from penetrating into the reserved gap, avoid mold and bacteria in the reserved gap, and is beneficial to the health of the space. It can also repair the cracks or damage on the surface of the surface material 70 well, has good adhesion and small shrinkage, so as to maintain the integrity and aesthetics of the surface material 70. Secondly, the caulking agent 80 not only has a beautiful appearance, but also solves the problem that the reserved seam is difficult to clean, thereby improving the indoor aesthetics. Exemplarily, the caulking agent 80 is implemented as an epoxy colored sand caulking agent 80. The epoxy colored sand caulking agent 80 has the characteristics of mildew resistance, alkali resistance, waterproofness, leakage resistance, high strength, wear resistance, stain resistance, acid and alkali resistance, corrosion resistance, and strong adhesion.

[0035] In summary, an aerated concrete wall surface material paving structure is provided in the embodiments of the present disclosure, which is for paving on an aerated concrete base layer, including a waterproof layer, which is applied on the aerated concrete base layer. A first plaster layer is laid on the waterproof layer; an anti-cracking layer is laid on the first plaster layer; and a second plaster layer is laid on the first plaster layer to cover the anti-cracking layer. A surface material, which is fixed to the second plaster layer by an adhesive layer. The waterproof layer is first applied on the surface of the aerated concrete base layer to improve the waterproof effect of the aerated concrete base layer. That is, the aerated concrete base layer can be prevented from absorbing the moisture in the first plaster layer and the second plaster layer, which is beneficial to the maintenance of the plaster layer. At the same time, it can also prevent the external moisture from being absorbed into the aerated concrete during the construction and application process, thereby preventing the aerated concrete from experiencing a decrease in strength and deformation.
