目前國(guó)家以及地方政府都有出臺(tái)鼓勵(lì)新能源的發(fā)展，在光伏領(lǐng)域，分布式光伏支架系統(tǒng)的身影在越來越多地方出現(xiàn)，成為備受青睞的太陽(yáng)能支架系統(tǒng)解決方案之一。
At present, the national and local governments have issued policies to encourage the development of new energy. In the solar field, residential and industrial solar mounting systems have emerged in more and more places, and become one of the most popular solar mounting system solutions.
下面我們來探討下分布式光伏里屋面防水的問題
Now let's discuss the problem of roof waterproofing in distributed solar
屋面防水處理的原則一般是通過導(dǎo)水槽達(dá)到排水的目的，即保證節(jié)點(diǎn)處理在暴雨積水時(shí)能順利的讓水瀉掉而保障屋面不漏。對(duì)于必須打孔破壞原屋面的情況，則要做到因地制宜，根據(jù)不同情況做不同處理，下面我們來具體分析下。
The principle of roof waterproof treatment is generally to achieve the purpose of drainage through the guide channel, that is, to ensure that the node treatment can smoothly let the water flow out and ensure that the roof does not leak when the storm water is accumulated. For the case that the original roof must be damaged by drilling, it is necessary to adjust measures to local conditions and make different treatment according to different conditions. Let's analyze it in detail.
混凝土平屋面光伏支架系統(tǒng)防水（Waterproofing of concrete flat roof solar mounting system）
對(duì)于新建造的建筑，通常在設(shè)計(jì)建筑的時(shí)候就按照常規(guī)做法，預(yù)埋螺栓，做好屋面防水。而對(duì)于已經(jīng)建造完成的建筑，在設(shè)置太陽(yáng)能組件基座時(shí)，防水層應(yīng)鋪設(shè)到基座和金屬埋件的上部，并在地腳螺栓周圍做密封處理，穿防水層處用防水密封膠填實(shí)，另外可以在基座下增設(shè)附加防水層，這樣即使基座頂部發(fā)生滲漏，雨水也不會(huì)到達(dá)結(jié)構(gòu)層。
For newly built buildings, bolts are usually embedded and roof waterproofing is done according to the conventional practice when designing buildings. For the buildings that have been built, when setting the solar module base, the waterproof layer should be laid on the upper part of the base and the metal embedded parts, and the sealing treatment should be done around the anchor bolts. The waterproof layer should be filled with waterproof sealant. In addition, an additional waterproof layer can be added under the base, so that even if there is leakage at the top of the base, the rain will not reach the structural layer.
化學(xué)錨固螺栓光伏支架系統(tǒng)防水（Chemical anchor bolt solar mounting system waterproof）
對(duì)于混凝土平屋面的已有建筑，若使用化學(xué)錨固螺栓固定支架，應(yīng)首先確認(rèn)保護(hù)層或使用面層的厚度。對(duì)于單位面積承重較大的預(yù)制樓板屋面，可在屋面現(xiàn)澆一定厚度的混凝土層，固化后利用化學(xué)錨固螺栓固定支架。
For existing buildings with concrete flat roof, if chemical anchor bolts are used to fix the mounting, the thickness of the protective layer or the surface layer used shall be confirmed first. For the prefabricated floor roof with large bearing capacity per unit area, a certain thickness of concrete layer can be cast in place on the roof, and the mounting can be fixed with chemical anchor bolts after curing.
對(duì)于上覆瓦片的坡屋面，應(yīng)確認(rèn)打孔深度，將化學(xué)錨固螺栓固定后，螺栓穿過瓦片的位置應(yīng)使用防水密封膠做良好處理?；瘜W(xué)錨固螺栓具有承載能力大，抗疲勞、耐老化等優(yōu)勢(shì)，對(duì)基體無膨脹力，不產(chǎn)生擠壓應(yīng)力，因此，不會(huì)對(duì)屋面防水造成不良影響。
For the sloping roof covered with tiles, confirm the drilling depth. After fixing the chemical anchor bolt, the position where the bolt passes through the tiles shall be well treated with waterproof sealant. The chemical anchor bolt has the advantages of large bearing capacity, fatigue resistance and aging resistance, and has no expansion force on the base and no extrusion stress. Therefore, it will not cause adverse impact on roof waterproofing.
金屬屋面光伏支架系統(tǒng)防水（Waterproofing of metal roof solar mounting system）
對(duì)于金屬屋面來說，需要將光伏系統(tǒng)的鋼結(jié)構(gòu)穿透原防水層及壓型鋼板，固定在建筑的主體鋼結(jié)構(gòu)上;再參照金屬屋面防水做法，進(jìn)行隔汽、保溫及防水處理。施工的重點(diǎn)是去銹蝕、密封、對(duì)基層及外圍涂刷防水涂料。
For the metal roof, the steel structure of the solar system needs to penetrate the original waterproof layer and profiled steel plate and be fixed on the main steel structure of the building; Then, steam insulation, thermal insulation and waterproof treatment shall be carried out with reference to the waterproof method of metal roof. The key points of construction are rust removal, sealing, and waterproof coating on the base and periphery.
對(duì)金屬屋面的局部漏點(diǎn)，應(yīng)采用優(yōu)質(zhì)中性耐候密封膠涂抹封堵;對(duì)于局部銹蝕嚴(yán)重的彩鋼板，在安裝光伏組件前需要更換。
Local leakage points of metal roof shall be sealed with high-quality neutral weatherproof sealant; The color steel plate with serious local corrosion needs to be replaced before installing the PV module.
因此，光伏支架系統(tǒng)的安裝設(shè)計(jì)不僅要考慮日照和陰影，承重、排水、防水等細(xì)節(jié)同樣值得被關(guān)注。晨科已經(jīng)為全球100多個(gè)國(guó)家的用戶解決光伏支架系統(tǒng)難題，去過雪地，也去過高山，還有湖泊農(nóng)田，如果你不知道如何選擇一套合適的太陽(yáng)能支架解決方案請(qǐng)聯(lián)系我們！
