Description
Technical Field
The invention relates to the technical field of bare concrete, in particular to a maintenance method and application of a bare concrete heat-insulating wallboard.
Background
Temperature cracks often occur on the surface of large volumes of concrete or in concrete structures in areas where temperature differences vary greatly. The larger temperature difference causes the difference of the expansion and contraction degrees between the inside and the outside, so that a certain tensile stress is generated on the surface of the concrete. When the tensile stress exceeds the tensile strength limit of concrete, cracks are generated on the surface of the concrete, and the cracks are mostly generated in the middle and later stages of concrete construction. When the temperature difference change is large in concrete construction or the concrete is impacted by cold waves, the temperature of the surface of the concrete is rapidly reduced to generate shrinkage, and the surface-shrunk concrete is restrained by the internal concrete to generate great tensile stress to generate cracks. In order to avoid the generation of cracks, in summer construction, a mode of pouring at night or in the morning is generally adopted to avoid the overlarge temperature difference between the inside and the outside of concrete, and also the generation of cracks is prevented by a mode of arranging temperature stress steel bars, and in winter construction with lower air temperature, the problem of the generation of cracks due to the larger temperature difference between the inside and the outside of the concrete can also occur, but the problem cannot be completely solved although the generation of the cracks can be reduced by a net hanging mode.
Along with the development of wall body heat preservation technology, the setting of heat preservation has set up the heat preservation from the wall body inside and outside and developed into setting up the hollow layer in the wall body inside, sets up insulation material in the hollow layer, and this kind of form can effectively avoid the wall body surface to set up the defect that the heat preservation drops easily, and convenient hoist and mount transportation, but also has certain defect simultaneously, like the wall body still does not have the problem of overcoming the difference in temperature crack completely, not only influences the heat preservation effect, can also influence wall body structure's stability. On the other hand, if the concrete bursts due to the corrosion of the reinforcing steel bars inside the wall, the service life of the wall may be further reduced, and such quality problems are not negligible today in high-rise buildings and super high-rise buildings. Finally, the new heat-insulating wall divides the original integrated wall into two parts, and although 2 walls are connected through connecting pieces, compared with the original 1 complete wall, the problem of strength reduction caused by structural change can also occur.
On the other hand, with the development of green buildings, energy stake technology is becoming more and more commonly used. The existing heat-insulating wall is rarely applied in combination with energy piles. The warm water supplied by the heat exchange tube of the energy pile can only walk along the heating pipeline in the building structure, and has no contribution to the improvement of the heat preservation efficiency of the heat preservation wall body and the daily maintenance of the wall body.
