Description

Technical Field

[0001] The utility model relates to the technical field of building materials, in particular to an indoor self-repairing anti-cracking heat-insulating and sound-insulating floor structure. Background Art

[0002] With the rapid development of the economy and the increasing growth rate of energy consumption, the requirements for energy-saving building design are becoming higher and higher. At present, the external structural system of buildings can basically meet people's needs, but the insulation and sound insulation technology inside the building is relatively weak. The key to insulation and sound insulation inside the building lies in the insulation and sound insulation of the ground. In the existing technology, the construction process of the insulation ground is to clean the base layer, lay the insulation board (EPS board, XPS board, PU board, etc.), lay the wire mesh and pour the concrete surface layer. The following problems are common when using this type of technology: (1) The insulation board and the base layer are prone to peeling, resulting in hollowing; (2) The shrinkage rate of the insulation board and the concrete surface layer is very different, resulting in uneven separation at the interface between the insulation board and the concrete, resulting in hollowing and cracking; (3) The junction between the insulation board and the surrounding walls is prone to separation, resulting in side seams.

[0003] Therefore, in order to overcome the shortcomings of thermal insulation and sound insulation floor structures in practical applications, it is necessary to solve the hollowing and cracking problems caused by the different shrinkage rates of the insulation board and the concrete base and surface layers, and at the same time, realize the self-repair and anti-cracking protection of the thermal insulation and sound insulation floor structure. At present, there are no related reports on the thermal insulation and sound insulation floor structure that have both self-repair and anti-cracking properties. Utility Model Content

[0004] The purpose of the utility model is to provide an indoor self-repairing anti-cracking thermal insulation and sound insulation floor structure to solve the deficiencies mentioned in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] The utility model discloses an indoor self-repairing anti-cracking thermal insulation and sound insulation floor structure, which comprises, from bottom to top, a floor base layer, a cement interface agent layer, a lightweight thermal insulation and sound insulation mortar layer, a self-repairing anti-cracking self-leveling mortar reinforcement layer and a finishing layer.

[0007] Furthermore, the cement interface agent layer adopts an emulsion cement interface agent. The emulsion cement interface agent is made of chemical polymer materials as the main component and supplemented with other fillers. It can enhance the bonding force to the ground base, has good water resistance, moisture resistance, and good frost resistance, and avoids hollowing and peeling between the insulation layer and the base.

[0008] Furthermore, the lightweight thermal insulation and sound insulation mortar layer adopts lightweight aggregate ceramsite mortar, the lightweight aggregate ceramsite mortar has a strength of LC20-LC30 and a dry density of ≤1000 kg / m3 , using 1-3mm, bulk density 500-600kg / m 3 , it is made of ceramic sand with a cylinder pressure strength of 1.6-2.0Mpa. The expanded clay mortar has excellent sound absorption and sound insulation effects due to its unique honeycomb structure and uniform small bubbles inside, and also has good thermal insulation properties.

[0009] Furthermore, the self-repairing anti-cracking self-leveling mortar reinforcement layer adopts microcapsule self-repairing self-leveling mortar. The repair principle of microcapsule self-repairing self-leveling mortar is: under the action of external load or environment, the cement material causes the microcapsules to rupture, and the outflowing polymer adhesive reacts with the air or the curing agent in the cement matrix to generate a substance with bonding ability, thereby inhibiting the expansion of cracks and repairing cracks, achieving the effect of restoring or even improving the strength of the material.

[0010] Furthermore, a reinforcing steel wire mesh is provided in the reinforcing layer of the self-repairing anti-cracking self-leveling mortar.

[0011] Furthermore, the finishing layer is a wooden floor, a ceramic tile or a stone.

[0012] Compared with the prior art, the advantages of the utility model are:

[0013] The utility model has reasonable structure, is easy to implement and has strong practicality. The bonding force between the base layer and the thermal insulation and sound insulation layer is strengthened through the cement interface agent layer, thereby avoiding hollowing and peeling between the thermal insulation and sound insulation layer and the base layer. Light aggregate ceramsite mortar is used as the thermal insulation and sound insulation layer, and self-leveling mortar is used as the reinforcement layer. Both are cement-based materials with almost the same shrinkage rate, so that hollowing, cracking, side seams and the like will not occur. At the same time, the microcapsule self-repairing self-leveling mortar layer can inhibit the expansion of cracks and repair cracks, thereby further inhibiting the generation of cracks. It has good market prospects and building energy-saving value. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0017] The following will be combined with the drawings in the embodiments of the utility model to describe the technical solutions in the embodiments of the utility model in detail. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of 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.

[0018] Combination Figure 1 As shown, the indoor self-repairing anti-cracking thermal insulation and sound insulation floor structure of the utility model comprises, from bottom to top, a ground base layer 1, a cement interface agent layer 2, a lightweight thermal insulation and sound insulation mortar layer 3, a self-repairing anti-cracking self-leveling mortar reinforcement layer 4, and a finishing layer 5.

[0019] The cement interface agent layer 2 adopts an emulsion type cement interface agent. The emulsion type cement interface agent is made of chemical polymer materials as the main component and supplemented with other fillers. It can enhance the bonding force to the ground base layer 1, has good water resistance, moisture resistance, and good frost resistance, and avoids the phenomenon of hollowing and peeling between the insulation layer 3 and the base layer 1.

[0020] The lightweight thermal insulation and sound insulation mortar layer 3 is made of lightweight aggregate ceramsite mortar, the strength of the lightweight aggregate ceramsite mortar is LC25-LC30, and the dry density is ≤1000 kg / m 3 , using 1-3mm, bulk density 500-600kg / m 3 , it is made of ceramic sand with a cylinder pressure strength of 1.6-2.0Mpa. The expanded clay mortar has excellent sound absorption and sound insulation effects due to its unique honeycomb structure and uniform small bubbles inside, and also has good thermal insulation properties.

[0021] The self-repairing anti-cracking self-leveling mortar reinforcement layer 4 adopts microcapsule self-repairing self-leveling mortar. The repair principle of microcapsule self-repairing self-leveling mortar is: the cement material ruptures the microcapsules under the action of external load or environment, and the outflowing polymer binder reacts with the air or curing agent in the cement matrix to generate a substance with bonding ability, thereby inhibiting the expansion of cracks and repairing cracks, achieving the effect of restoring or even improving the strength of the material.

[0022] A reinforcing steel wire mesh 6 is provided in the self-repairing anti-cracking self-leveling mortar reinforcing layer 4 .

[0023] The finishing layer 5 is a wooden floor, a ceramic tile or a stone.

[0024] During the specific construction of the utility model, a cement interface agent layer 2 is evenly rolled on the ground base layer 1, and after the cement interface agent layer 2 is dried, a lightweight thermal insulation and sound insulation mortar layer 3 is poured, and after the lightweight thermal insulation and sound insulation mortar layer 3 is solidified, a self-repairing and anti-cracking self-leveling mortar reinforcement layer 4 is poured for leveling, and finally a decorative surface layer 5 is installed.

[0025] The utility model has reasonable structure, is easy to implement and has strong practicality. The cement interface agent layer 2 is used to strengthen the bonding force between the base layer 1 and the thermal insulation and sound insulation layer 3, thereby avoiding the phenomenon of hollowing and peeling between the thermal insulation and sound insulation layer 3 and the base layer 1. Light aggregate ceramsite mortar is used as the thermal insulation and sound insulation layer 3, and self-leveling mortar 4 is used as the reinforcement layer. Both are cement-based materials, and their shrinkage rates are almost the same, so that hollowing, cracking, side seams and the like will not occur. At the same time, the microcapsule self-repairing self-leveling mortar layer 4 can inhibit the expansion of cracks and repair cracks, further inhibiting the generation of cracks. It has good market prospects and building energy-saving value.

[0026] The above is only a specific implementation of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
