1彩钢板结构连接件
（1） 彩钢板结构连接件的强度：结构连接件的主要功能是抗风吸力。因此，应考虑连接件本身的拉伸性能、连接件与受力构件的拉拔性能、连接件下彩钢板因风吸力引起的拉拔性能。在上述三种情况下，第三种表现往往较弱。在购买自攻螺钉和其他连接器时，只能提供前两项的机械性能。第三个性能与彩板厚度、区域风荷载、建筑外形、钢板材料等有关，这些因素不能自连接。为了解决这一问题，国外一些公司进行了实验，并用经验公式进行了计算。以下公式是某公司提出的供参考的公式。
（2） 结构连接件的表面处理：结构连接件的使用寿命应与彩板建筑材料的使用寿命相匹配，因此需要对钢制连接件进行表面处理。目前有自镀、镀锌等多种自攻自攻涂层。涂层和涂层的厚度也不同。订货时应根据建筑物的重要性进行选择，供货商应提供标准技术资料供选择。
（3） 结构连接件上的密封垫是连接件的重要组成部分。它可以防止雨水从板上的孔中渗入。因此，在选择自攻螺钉时，应提出密封垫圈的使用寿命要求。其使用寿命应与彩板部件的使用寿命相匹配，并应具有良好的密封性能和抗老化性能。
2彩钢板结构连接件
自攻螺钉和铝合金铆钉通常用于结构连接件。选择要求与结构连接件相同。选用铝合金铆钉时应选用铝合金铆钉，不允许使用纯铝铆钉。室外使用应选用闭孔铝合金铆钉。在色板部件上使用时，应特别注意密封问题。一般情况下，密封胶的密封头往往不能满足施工条件和施工人员的要求。因此，建议在铝合金铆钉上使用耐老化性能好的密封垫。
三。彩钢板连接件数量的计算
工程中使用的连接件种类和数量比较复杂，需要分类计算。在初步设计（估算）阶段，一般采用平方米或延米的消耗量进行计算；在施工材料准备阶段，应按实际消耗量进行计算，计算结果应加上5%左右的损失，以弥补损失，施工过程中的损失和变化。
4彩钢板连接器的检验和包装
连接器通常由专业制造商生产和供应。收货时应有出厂合格证、材料清单、技术性能证明等，一般情况下使用时无需检验，但应检验装箱交付产品的规格、型号和数量。连接器的包装，盒内交付的连接器应为盒装，自制的连接器也应装箱，并在盒上注明型号和件数。

1. Color steel plate structural connector

(1) Strength of color steel plate structural connector: the main function of structural connector is to resist the wind suction. Therefore, the tensile performance of the connector itself, the pull-out performance of the connector and the load-bearing structural member connected, and the pull-out performance of the color steel plate under the connector caused by wind suction should be considered. In the above three cases, the third performance is often weak. When purchasing self tapping screws and other connectors, the mechanical properties of the first two items can only be provided. The third performance is related to the thickness of color plate, regional wind load, building shape, steel plate material, etc., which can not be self connected. In order to solve this problem, some foreign companies have carried out experiments and calculated with empirical formula. The following formula is proposed by a company for reference.
(2) Surface treatment of structural connectors: the service life of structural connectors should match the service life of color board building materials, so the surface treatment of steel connectors should be required. At present, there are many kinds of self tapping screws, such as zinc plating, aluminum plating and organic coating after coating. The thickness of coating and coating is also different. When ordering, it should be selected according to the importance of buildings, and the supplier should provide standard technical data for selection.
(3) the sealing gasket on the structural connector is an important part of the connector. It prevents the rain from infiltrating from the holes in the plate. Therefore, when choosing self tapping screws, the service life and sealing requirements of the sealing washer should be put forward. Its service life should match the service life of the color plate components, and it should have good sealing performance and anti-aging performance.
2. Color steel plate structural connector
Self tapping screws and aluminum alloy rivets are often used for structural connectors. The selection requirements are the same as those for structural connectors. Aluminum alloy rivets should be selected when aluminum alloy rivets are selected, and pure aluminum rivets are not allowed. Closed hole aluminum alloy rivets should be selected for outdoor use. Special attention should be paid to the sealing problem when using on color plate components. Generally, the sealing head of sealant is often not satisfied with the construction condition and the construction personnel. Therefore, it is suggested that the sealing gasket with good ageing resistance should be used on the aluminum alloy rivet.
3. Calculation of the amount of color steel plate connector
The type and quantity of connectors used in an engineering project are complicated and should be calculated by classification. In the preliminary design (estimation) stage, the consumption of square meters or extended meters is generally used for calculation; in the construction material preparation stage, the calculation should be based on the actual consumption, and the calculation results should be added with about 5% of the loss to make up for the damage, loss and changes in the construction process.
4. Inspection and packaging of color steel plate connector
Connectors are generally produced and supplied by professional manufacturers. When receiving the products, there should be factory certificate, material list and technical performance certificate, etc. generally, there is no need to test when using, but the specifications, models and quantities of the products delivered in boxes should be inspected. For the packaging of connectors, the connectors delivered in boxes shall be delivered in boxes, and the self-made connectors shall also be packed in boxes, and the model and number of pieces shall be indicated on the box.
