钢结构棚是一种常见的建筑形式。其主要功能是保护车辆免受风和雨的影响，保护车辆免受大雨和暴晒。作为雨棚，最重要的是要有良好的防雨性能，但是很多钢雨棚都会有漏雨的问题。无论采用何种类型的钢结构雨棚，雨水渗漏的原因不超过三个，一是设计原因，二是施工安装原因，三是材料本身。你能避免这些漏洞百出的“陷阱”吗？

首先是设计的原因。钢结构雨棚设计不合理易导致漏雨，主要表现在屋面弯曲过大或坡度过缓，水流速度过慢，造成积水，落水管管径不理想，面板选择不当，修边及天沟节点设计不合理。为了避免这个“陷阱”，找到一家专业的钢结构设计公司是非常重要的。
其次，不合理的施工安装容易导致雨水渗漏，主要表现在接缝处理不当、连接不慎、防水材料不足、封闭胶不严、螺丝安装不慎等，以避免这种“陷阱”
三是材料本身特性造成的漏水隐患。例如，金属板本身的导热系数很大。当外界温度变化较大时，由于环境温差变化较大，材料因温度变化而收缩变形，导致界面位移较大，造成漏水隐患；在钢结构体系中，由于温度变化、风荷载、雪荷载等外力作用，结构本身在连接部位容易发生弹性变形和位移，造成漏水隐患。要避免这个“陷阱”并不容易。我们需要在材料的选择和应用上下功夫，依靠及时的维护。

Steel structure shed is widely seen. Its main function is to protect vehicles from wind and rain and protect vehicles from heavy rain and exposure. As a canopy, the most important thing is to have good rainproof performance, but many steel canopy will have the problem of rain leakage. Based on the experience of Dadi Yunlong steel structure, no matter what type of steel structure canopy is adopted, there are no more than three reasons for rain leakage, one is the design reason, the other is the construction and installation reason, and the third is the material itself. Can you avoid these leaky "traps"?

The first is the reason of design. The unreasonable design of steel structure canopy is easy to lead to rain leakage, which is mainly reflected in, for example, the roof winding is too large or the slope is too slow, and the water flow speed is slow, resulting in ponding, unsatisfactory downpipe diameter, improper panel selection, unreasonable edge trimming and gutter node design. To avoid this "trap", it is very important to find a professional steel structure design company.
Secondly, unreasonable construction and installation can easily lead to rain leakage, which is mainly reflected in improper joint treatment, careless connection, inadequate waterproof materials, lax closing glue, careless installation of screws, etc. To avoid this "trap", we should find a professional Wuhan steel structure company to complete this seemingly simple task.
The third is the hidden danger of water leakage caused by the characteristics of the material itself. For example, the thermal conductivity of the metal plate itself is large. When the external temperature changes greatly, due to the large change of environmental temperature difference, the material shrinks and deforms due to the temperature change, resulting in large displacement at the interface, resulting in hidden dangers of water leakage; In the steel structure system, due to the temperature change, wind load, snow load and other external forces, the structure itself is prone to elastic deformation and displacement at the connection parts, resulting in hidden dangers of water leakage. It is not easy to avoid this "trap". We need to work hard on material selection and application, and rely on timely maintenance.
