Problems solved by technology

In a short period of time, the flatness of the site is very good, but after a long time, there will be water accumulation on the cement base of the site, which cannot be discharged. In addition to the sunlight and the influence of temperature, the accumulation water evaporates into water vapor, which is harmful to the synthesis. The surface layer forms a certain pressure, which will push up the synthetic surface layer and form various air bubbles, which will cause unevenness of the sports field, affect the use, and even be damaged

Embodiment Construction

[0024] Figure 1 ~ Figure 3 Shown is a cast-in-place synthetic material surface breathable membrane 10 , the breathable membrane 10 includes a plurality of mesh holes 12 , and the bottom has an air channel 11 sunken inward and extending to the end of the breathable membrane 10 . The breathable membrane 10 can be made of polyethylene, and the thickness can reach about 1 mm. The mesh 12 can be in various shapes, such as circular, square and so on. The area of ​​the mesh 12 is greater than 50% per square meter, that is, to ensure that the surface bonding area of ​​the synthetic material surface layer 14 and the concrete base layer 13 should be greater than 50% per square meter to enhance stability.

[0025] refer to figure 1 , figure 2 , The breathable membrane 10 can be integrally formed, similar to a mesh structure, the air channels 11 at the bottom are criss-crossed, and there are multiple mesh holes 12 (through holes) in the middle.

Abstract

The invention relates to a cast-in-place synthetic material surface gas-breathable film. The gas-breathable film comprises a plurality of meshes, and air passages which are sunken inwardly and extendto an end of the gas-breathable film are formed in the bottom of the gas-breathable film. The gas-permeable film is laid on the surface of a concrete base layer, and a synthetic material is bonded tothe surface of the concrete base layer through the plurality of meshes of the gas-permeable film during the cast-in-place and is solidified to form a synthetic material sports surface layer. The gas-permeable film laid on the surface of the concrete base layer forms a suspension venting gap with the surface of the concrete base layer under the compression of the synthetic surface layer, so that gas evaporating from the surface of the concrete base layer at a high temperature can be directly discharged from the gap.

Description

technical field [0001] The invention belongs to the technical field of synthetic material surfaces, and in particular relates to a cast-in-place synthetic surface breathable membrane, a synthetic surface sports field and a construction process. Background technique [0002] When laying plastic sports fields, the surface layer of non-water-permeable synthetic materials is generally cast-in-place directly on the cement base. In a short period of time, the flatness of the site is very good, but after a long time, water will form on the cement base of the site, and the water cannot be discharged. In addition to the sunlight and the influence of temperature, the water evaporates into water vapor, which has a negative effect on the synthesis. The surface layer forms a certain pressure, which will push up the synthetic surface layer and form various air bubbles, which will cause unevenness of the sports field, affect the use, and even be damaged.
