彩鋼板的接縫構造處理措施

來源:http://www.ebassfish.com/ 日期:2021-07-23 發布人:jiangucaigang
當單面坡長小于12m時,屋面可不設橫縫;當單面坡長大于12m時,彩鋼板間需設橫縫搭接。橫縫一般采用順水搭接,為保證防水效果,必須滿足一定的搭接長度,且搭接長度長短與屋面坡度有關,當坡度小于等于1/10時,一般不宜小于300mm;當坡度大于1/10時,一般不宜小于200mm,并要求在搭接處高低錯開,上下兩層板之間粘貼防水密封膠條。
When the single side slope length is less than 12M, the roof may not be provided with transverse joints; When the slope length of one side is greater than 12M, transverse joints shall be set between color steel plates. The transverse joints are generally overlapped along the water. In order to ensure the waterproof effect, a certain overlapping length must be met, and the overlapping length is related to the roof slope. When the slope is less than or equal to 1 / 10, it should generally not be less than 300mm; When the slope is greater than 1 / 10, it shall not be less than 200mm generally, and the height of the lap joint shall be staggered, and the waterproof sealant strip shall be pasted between the upper and lower layers of plates.
這樣不僅可有效防止滲水,還可防止鋼板切口處氧化銹蝕。同時應注意搭接處一般采用自攻螺釘固定在波峰位置。若設置在波谷上,必須要有可靠的防水措施。
This can not only effectively prevent water seepage, but also prevent oxidation and corrosion at the notch of the steel plate. At the same time, it should be noted that the lap joint is generally fixed at the wave crest position with self tapping screws. If it is set on the trough, reliable waterproof measures must be taken.
屋面低波彩鋼板用連接件直接與檁條連接,每波或隔一個波設置一個,但搭接波處必須設置連接件。屋面高波彩鋼板用連接件與固定支架連接,每波設置一個。
The roof low wave color steel plate is directly connected with the purlin with connectors, one for each wave or every other wave, but connectors must be set at the overlapping wave. The roof high wave color steel plate is connected with the fixed support with connectors, one for each wave.
另一種上下板連接方法是壓板擠緊法,在兩塊彩鋼板的上面和下面各設一塊與彩鋼板板型相同的鍍鋅鋼板,兩板間設防水密封條,用緊固螺栓將其緊密擠壓連接在一起。為避免板的長向搭接處引起漏水,也可將壓型板生產設備運至現場安裝,軋制從屋脊到檐口的整張屋面板,邊軋制邊安裝,無需長向搭接,避免不必要的滲漏。
Another method for connecting the upper and lower plates is the pressing plate extrusion method. A galvanized steel plate with the same plate type as the color steel plate is set above and below the two color steel plates, and a waterproof sealing strip is set between the two plates, which are tightly extruded and connected together with fastening bolts. In order to avoid water leakage at the long lap joint of the plate, the profiled plate production equipment can also be transported to the site for installation. The whole roof panel from the ridge to the cornice can be rolled and installed while rolling. There is no need for long lap joint to avoid unnecessary leakage.
通常情況下,選用長板不搭接好,但在實際工程中發現,板過長時,由于溫度影響板的伸縮會引起螺孔擴張而產生滲漏;同時,由于板過長,在制造、運輸或施工過程中易損傷涂層,影響質量。
In general, it is not good to select long plates, but it is found in practical engineering that when the plate is too long, the expansion of screw holes will be caused by the expansion of screw holes due to the influence of temperature; At the same time, because the plate is too long, it is easy to damage the coating and affect the quality during manufacturing, transportation or construction.
