Description
Technical Field
The invention relates to a waterproof installation method for a roof photovoltaic bracket support.
Background
The first installation of waterproof installation of the existing roof photovoltaic support is shown in figure 3, and the support of the installation support of the sloping roof is positioned firstly and then the tile is uncovered or the tile is cut according to the size; hole site is fixed through the support base plate for punching operation, and the support base plate is fixed on the cast-in-situ layer through expansion bolts or chemical bolts after the hole is punched; and (3) carrying out concrete backfill after fixing the support, and then carrying out a layer of water prevention on the backfilled concrete after backfill.
Waterproof installation second installation of current roof photovoltaic support: and (3) directly punching holes on the tile or a cast-in-situ layer, fixing a support or a cross beam by using expansion bolts or chemical bolts, and then directly making a waterproof layer on the uppermost area extending out of the tile surface.
Waterproof third installation of current roof photovoltaic support: and (3) directly punching holes on the cast-in-situ layer under the tile, and fixing the support by using expansion bolts or chemical bolts to extend out of the joint of the tile without any waterproof treatment.
The three mounting modes have the following defects:
1. the support or the cross beam is fixed on the roof slope tile, the original roof waterproof layer is penetrated by the holes, the waterproof is only carried out at the support connecting part on the tile surface, the waterproof layer under the tile cannot be repaired, and water leakage can occur due to waterproof aging on the tile in the later stage.
2. The support is perforated and penetrated through the original roof waterproof layer after the cast-in-situ layer below the tile is perforated and fixed, the support is directly backfilled with concrete without treatment and then waterproof is carried out at the position of the support extending out of the tile, and water leakage can occur after later aging.
3. All building roofs are integrally waterproof on cast-in-situ layers before acceptance delivery, and because the photovoltaic support is firmly fixed on the slope roof cast-in-situ layer bearing structure by virtue of perforation, the bearing structure is required to be perforated, thus the integral roof waterproof layer is necessarily damaged, and water leakage can occur in the later stage (roof waterproof event is a worldwide problem).
4. Only waterproof is made on the tile, and later support rust or shaking loose water can directly flow back from the tile to a cast-in-place layer below the tile, so that the roof water leakage problem is caused.
Disclosure of Invention
The invention aims to solve the problem of water leakage on the roof surface caused by the installation of a photovoltaic support seat on the roof in the background art, and provides a waterproof installation method for the photovoltaic support seat on the roof. The method is suitable for various roofs such as slope concrete roofs, tile roofs, glazed tile roofs, other asphalt felts and the like of cast-in-situ layers under the roofs, and is especially suitable for scenes with strict requirements on wind resistance and water resistance.
The technical scheme adopted by the invention is as follows:
the waterproof installation method of the roof photovoltaic support is characterized by comprising the following steps of:
firstly, punching a roof concrete cast-in-situ layer after a roof positioning notch, uniformly injecting sealant into the hole, uniformly coating the sealant on the bottom of a photovoltaic support, inserting an expansion bolt into a bottom plate hole of the photovoltaic support from top to bottom, and then inserting the expansion bolt into the hole of the roof concrete cast-in-situ layer together to fasten a nut, wherein the first internal waterproof treatment is carried out;
step two, uniformly brushing waterproof paint twice on the upper surface of the fixed photovoltaic support base plate and the roof concrete cast-in-situ layer in a closed mode, wherein the waterproof paint is the second internal waterproof treatment of the invention; pouring the uniformly stirred concrete mortar into the notch on the roof for backfilling, and trowelling and compacting along with the drainage gradient of the roof;
and thirdly, uniformly brushing waterproof paint on the upper surface of the concrete mortar after the concrete mortar is maintained and dried in the sun, wherein the waterproof paint is the third waterproof treatment of the upper surface of the concrete mortar.
And in the first step, the cast-in-situ layer of roof concrete is perforated by an electric hammer with the diameter of a drill bit of 10 mm.
The sealant used in the first step is weather-proof sealant.
The beneficial effects of the invention are as follows:
the support is fixed on the concrete cast-in-situ layer by adopting the cut roof, so that the support has obvious installation effect on typhoon areas and large-area structures with large wind power, firm overall waterproof structure and attractive function, and is convenient to install and detach. After the original waterproof layer in the concrete cast-in-place layer of the roof is damaged, the original waterproof layer is subjected to waterproof treatment of sealant and twice waterproof coating, so that repair and lamination with the original waterproof layer are ensured, the surface layer waterproof treatment is performed on the roof again, the roof is guaranteed to be watertight, and three times of waterproof two-layer insurance is realized. The method is suitable for various roofs such as slope concrete roofs, tile roofs, glazed tile roofs, other asphalt felts and the like of cast-in-situ layers under the roofs, and is especially suitable for scenes with strict requirements on wind resistance and water resistance.
