Description
Technical Field
The invention relates to the field of building waterproof construction, in particular to a construction method of a wet-laid waterproof heat-insulation integrated plate.
Background
The roof is used as a very important enclosing structure of a building, and the main functions of the roof are water resistance and heat preservation. The traditional roof construction method is divided into a positive construction method and an inverted construction method. The upright method is to place the waterproof layer on the heat-insulating layer, and the inverted method is to place the waterproof layer under the heat-insulating layer. In addition, in the traditional roof system, the waterproof and heat-insulating layers are subjected to separate construction of different work types.
For the forward-mounted method, because the waterproof layer is arranged on the heat-insulating layer, although the heat-insulating effect reduction caused by water inflow of the heat-insulating layer can be avoided to a certain extent, the forward-mounted method is easy to form water channeling, once the leakage is difficult to maintain in the later stage, large-area grouting for stopping leakage, even the construction level on the original structural plate is completely dug, and the cost is huge. The waterproof layer is arranged under the heat preservation in the inversion mode, water channeling can be effectively avoided, the waterproof layer can also be effectively protected, the whole waterproof effect is good, however, the heat preservation does not have the protection of the waterproof layer at the upper part of the heat preservation, the heat preservation is easy to feed water, the heat preservation effect is reduced due to long-term soaking, the freezing and thawing phenomenon can occur in winter, and then the protection surface layer of the roof is damaged. In addition, in the traditional roof construction method, regardless of the forward-mounted method or the reverse-mounted method, the waterproof and heat preservation separate construction is easy to influence each other, the mutual withering can be carried out when problems occur, the responsibility is not clear, the overall structure level of the roof is complex, and the construction period is long.
Therefore, more and more roofs adopt the idea of integration, the waterproof layer and the heat preservation layer are compounded into an integrated plate, then the integrated plate is bonded with the base layer through the bonding layer, and two functions of water prevention and heat preservation are completed through one process.
At present, the waterproof and heat-preservation integrated system has two paving and pasting modes, one mode is to bond the base layer through rubber asphalt coating, and the other mode is to bond the base layer through cement-based bonding material. Because the rubber asphalt coating is always in an uncured state, when the rubber asphalt coating is subjected to external load or environmental temperature change, the rubber asphalt coating is easily in a state of uneven thickness or even flowing, so that the phenomenon of hollowing of the plate and the base layer is caused, the leakage hidden danger in the later period is large, the requirement on the water content of the base layer is high during the construction of the rubber asphalt coating, and the construction period is influenced during the construction in rainy seasons. And the cement-based material (such as cement mortar, cement paste and the like) is bonded with the base layer, so that the requirements on the flatness and the water content of the base layer are not high, the construction is more convenient, and the full-bonding effect is more easily achieved. However, no matter which construction mode is adopted, manual operation is mainly adopted at present, the thickness of the bonding layer mainly depends on the proficiency of constructors, once the thickness of the bonding layer of the plate and the base layer is not well controlled, the phenomenon of plate hollowing can be caused, the construction efficiency of manual operation is not high, and the construction period can be influenced to a certain extent.
Therefore, some solutions for waterproof and heat-insulating integrated boards are proposed in the prior art, for example, a waterproof and heat-insulating integrated board disclosed in the chinese patent application No. 201711282890.X and an integrated board convenient to roll up disclosed in the chinese patent with publication No. CN 206070891U.
In addition, some automatic paving equipment for waterproof rolls are disclosed in the prior art, for example, a waterproof roll paver and a paving method disclosed in chinese patent publication No. CN104912266B, a hot-melt paving waterproof roll locomotive disclosed in publication No. CN107366394A, a roll paving forming machine and a paving method of waterproof rolls disclosed in publication No. CN107859252A, and an automatic glue spraying and paving all-in-one machine for waterproof rolls disclosed in publication No. CN 110158875A.
However, the above waterproof roll material laying equipment is not suitable for laying the integrated board, and the waterproof and heat-insulating integrated board is mainly constructed manually at present, so that the construction efficiency is low, and therefore, a laying scheme for the waterproof and heat-insulating integrated board needs to be provided.
