Description

Wind-resistant reinforcing system for ultra-long metal roof panel

Technical Field

The utility model relates to a metal roofing field, concretely relates to system is strengthened to overlength metal roof boarding anti-wind.

Background

With the rapid development of domestic economy, buildings embodying green and humanity are increasingly becoming necessary requirements for the development of the building field, and architectural artistic forms are increasingly diversified to embody landmark characteristics, so that more and more public buildings appear in the visual field of people, such as exhibition centers, stadiums, large-scale transportation public buildings and the like. In order to better reflect the artistic effect of buildings, large metal roofs are widely applied to public buildings, compared with traditional concrete roofs and tile roofs, the metal roofs have the advantages of light weight, good plasticity, strong deformation adaptability and the like, and after long-time application, architects have more and more strict requirements on the shape and performance of buildings.

In many research subjects of metal roofs, wind resistance is one of the existing and very important subjects, the traditional vertical overlock metal plate is only connected with a support in an occlusion way by plate ribs of roof plates on two sides in order to ensure free sliding of the roof plates and the connection support, the occlusion surface is small, the vertical overlock metal plate is mostly suitable for low wind pressure areas, the roof plates are easy to deform under the action of negative wind pressure in areas with large wind pressure, when the roof plates deform too much, the plate ribs of the roof plates can be separated from the support, the roof plates are turned over by wind, and domestic large-scale metal roofs are often turned over by wind.

In order to meet the function and modeling requirements of public buildings, the length of some roof panels needs to be more than 80m, even more than 100 m. This kind of overlength roof boarding, the flexible volume of roof boarding that arouses by ambient temperature change is great, and the change of temperature is relapse, thereby roof boarding's flexible also is relapse, this makes roof boarding rib and fixing support can rub repeatedly, and then make roof boarding rib and fixing support interlock not hard up, so the wind-resistant performance of this kind of overlength roof boarding is relatively weaker than the roof boarding of ordinary length, and when the wind pressure that produces was used on overlength roof boarding, it takes place deformation more easily, influence its life, consequently, guarantee that the wind-resistant performance of overlength metal roof boarding just becomes one of key point.

The method for increasing the wind resistance of the existing metal roof comprises the following steps: the space between roof purlines is reduced (actually, the purlines are increased), the cross section of the roof purlines is increased (the wind resistance strength of the purlines is increased), and the like, if the roof purlines are used for construction of an ultra-long metal roof panel, although certain wind resistance performance can be achieved, technical problems in other aspects are brought along, on one hand, the integral constant load of a roof system is increased, the load burden of the structure is caused, and even the safety load limit reserved by a main structure is possibly exceeded, and the potential safety hazard of engineering is caused; on the other hand, the traditional treatment method causes the construction process to be complicated, the construction period to be prolonged virtually, a large amount of construction cost is increased, and the profit of the project is reduced.

The problem of wind resistance of the ultra-long metal roof panel is solved fundamentally, the stress condition of the ultra-long metal roof panel under the condition of larger negative pressure needs to be fully mastered, and the problem is solved only by strengthening wind uncovering resistance construction starting from key construction nodes.
