Description

An indoor moisture-proof and crack-resistant ground structure

technical field

The utility model relates to the field of building indoor ground structures, in particular to an indoor moisture-proof and crack-resistant ground structure.

Background technique

Nowadays, my country's new rural construction is in full swing, but there are still many problems in the new rural buildings. The indoor floor of the first floor of the building is usually directly hardened with concrete on the rammed plain soil base and then paved with a decorative layer. Although the structure of this indoor floor is simple, it is very easy to cause "resurrection". Especially in the south of my country, due to the more rain in summer and the humid climate, a layer of water dew often appears on the indoor floor before and after the rain, which causes great inconvenience to life. Therefore, in view of the phenomenon of "returning moisture" on the indoor ground of rural buildings in our country, the existing ground structure needs to be improved urgently.

Contents of the invention

In order to avoid the disadvantages of the above-mentioned indoor ground structure of the existing rural buildings, the purpose of this utility model is to provide an indoor moisture-proof and crack-resistant ground structure with simple structure, convenient construction, and effective prevention of "moisture return".

In order to achieve the above object, the technical solution of the utility model is achieved in that:

An indoor moisture-proof and crack-resistant ground structure, comprising a rammed ground base 1, a fine sand layer 2 laid on the rammed ground base 1, a composite geomembrane moisture-proof layer 3 laid on the fine sand layer 2, and a concrete hardened layer laid on the composite geomembrane moisture-proof layer 3 4. A fiber mesh cloth layer 5 is laid on the hardened concrete layer 4, and a crack-resistant mortar layer 6 is laid on the fiber mesh cloth layer 5.

The composite geomembrane moisture-proof layer 3 includes a common geomembrane and a fiber mesh cloth pasted on the surface of the common geomembrane.

The fine sand layer 2 is 5-10mm.

The concrete hardening layer 4 is 40-50mm.

The beneficial effects of the utility model:

1. On the one hand, the fine sand layer 2 can improve the flatness of the compacted ground base 1, and at the same time, it can play a certain role of buffer protection, so as to avoid damage to the composite geomembrane moisture-proof layer 3 due to the unevenness of the compacted ground base 1;

2. The composite geomembrane moisture-proof layer 3 can effectively prevent underground moisture from penetrating upwards, and has good mechanical properties, and can be well combined with the hardened concrete layer 4 when the upper layer of concrete is poured.

3. Both the fiber mesh cloth layer 5 and the anti-crack mortar layer 6 can effectively prevent cracks in the indoor ground structure.

Description of drawings

Fig. 1 is a schematic diagram of the overall structure provided by the utility model.

detailed description

Below in conjunction with accompanying drawing, structural principle and working principle of the present utility model are described in detail.

Referring to Fig. 1, an indoor moisture-proof and anti-cracking ground structure includes a compacted ground base 1, a fine sand layer 2 is laid on the compacted ground base 1, a composite geomembrane moisture-proof layer 3 is laid on the fine sand layer 2, and the composite geomembrane moisture-proof layer A hardened concrete layer 4 is laid on the hardened concrete layer 4, a fiber mesh cloth layer 5 is laid on the hardened concrete layer 4, and a crack-resistant mortar layer 6 is laid on the fiber mesh cloth layer 5.

The composite geomembrane moisture-proof layer 3 includes a common geomembrane and a fiber mesh cloth pasted on the surface of the common geomembrane.

The fine sand layer 2 is 5-10mm.

The concrete hardening layer 4 is 40-50mm.

Working principle of the utility model:

When in use, first spread a 5-10 mm fine sand layer 2 on the rammed ground base 1. On the one hand, the fine sand layer 2 can improve the flatness of the rammed ground base 1, and at the same time can play a certain role in buffering and protecting, avoiding the The unevenness of 1 leads to the damage of the composite geomembrane moisture-proof layer 3, and the composite geomembrane moisture-proof layer 3 is laid on the fine sand layer 2. The composite geomembrane moisture-proof layer 3 is formed by pasting a layer of fiber mesh cloth on the upper surface of the ordinary geomembrane. Composed of composite materials, the composite geomembrane moisture-proof layer 3 can effectively prevent underground moisture from penetrating upwards, and has good mechanical properties. When the upper layer of concrete is poured, it can be well combined with the concrete hardened layer 4. The composite geomembrane moisture-proof layer 3 The concrete hardened layer 4 on the top is 40-50 mm. After pouring the concrete hardened layer 4 and before it hardens, lay fiber mesh cloth 5 on its surface and close the surface with an anti-crack mortar layer 6, which can effectively prevent the indoor ground structure from Cracks appear.
