    1、屋面檩条、墙梁 装置终了,就可停止屋面、墙面彩钢板的装置。普通是先装置墙面彩钢板,后装置屋面彩钢板,以便于檐口部位的衔接。彩钢板装置有躲藏式衔接和自攻螺丝衔接两种。躲藏式衔接经过支架将彩钢板固定在檩条上,彩钢板横向之 间用咬口机将相邻彩钢板搭接口咬接,或以防水粘结胶粘接(这种做法仅适用于屋面)。自攻螺丝衔接是将彩钢板直接经过自攻螺丝固定在屋面檩条或墙梁上,在 螺丝处涂防水胶封 口,这种办法可用于屋面或墙面彩钢板衔接。彩钢板在纵向需求接长时,其搭接长度满足设计请求,普通≥250mm,并用自攻螺丝衔 接,防水胶封口。
    1. When the roof purlin and wall beam devices are finished, the roof and wall color steel plate devices can be stopped. Generally, the wall color steel plate is installed first, and then the roof color steel plate is installed to facilitate the connection of the eaves. There are two kinds of color steel plate devices: hiding connection and tapping screw connection. Hidden connection fixes the color steel plate on purlin through bracket. The color steel plate overlaps the adjacent color steel plate with biting machine across the purlin, or is bonded with waterproof adhesive (this method is only applicable to roof). Self-tapping screw connection is to fix the color steel plate directly through the self-tapping screw on the purlin or wall beam of the roof, and coat the waterproof glue seal on the screw. This method can be used for the connection of the color steel plate of the roof or wall. The lap length of color steel plate meets the design requirement when the longitudinal demand is long. It is more than 250 mm in common. It is connected with self-tapping screw and sealed with waterproof glue.

    2、彩钢板装置中, 应留意几个关键部位的结构做法:山墙檐口处,用檐口包角板衔接屋面和墙面彩钢板;屋脊盖板,可依据屋面的坡度大小,分屋面坡度大于或等于10°和小于10°两种不同的做法 ;门窗位置,依窗的两侧设立窗边立柱,立柱与墙梁衔接固定,在窗顶、窗 台处设墙梁,装置 彩钢板墙面时,在窗顶、窗台、窗侧分别用不同规格的衔接板包角处置;墙面转角处,用包角板衔接外墙转角处的接口彩钢板;

    2. In the colored steel plate installation, attention should be paid to the structural practices of several key parts: at the eaves of the gable, the roof and the wall colored steel plates are joined by the corner-wrapped eaves; the roof roof plate can be divided into two different methods: the roof slope is greater than or equal to 10 degrees and less than 10 degrees according to the slope of the roof; the window side pillars are set up on both sides of the window, and the pillars are connected with the wall beams and fixed on the roof of the window. When installing the colored steel plate wall, the wall beams are arranged at the window sill, and the corner of the window roof, the window sill and the window side are respectively covered with different specifications of the connecting plate; at the corner of the wall, the corner plate is used to connect the colored steel plate at the corner of the external wall;
    3、天沟装置,内天 沟多采用不锈钢制品用不锈钢支撑固定在檐口的边梁(檩条)上,支撑架的间距约500mm,用螺栓衔接。另 外,内天沟也有采用2-3mm钢板压制水槽的做 法,而且在水槽内侧涂上沥青油防腐。外天沟多采用彩板制品,用支撑固定在檐口的屋面板上。
    3. Tiangou device, the inner Tiangou mostly uses stainless steel products to support and fix on the side beam (purlin) of the eaves. The spacing of the support frame is about 500 mm, which is connected by bolts. In addition, the inner trench also uses 2-3mm steel plate to press the water tank, and the inside of the tank is coated with asphalt oil to prevent corrosion. Outer Tiangou is mostly made of coloured panel products, which are fixed on the roof panel of eaves with support.
