Slipping type connecting device for building roofs

Abstract

The invention provides a slipping type connecting device for building roofs. The connecting device comprises an upright side locked aluminium-magnesium-manganese alloy profiled plate and an aluminium alloy support which are connected with a structural keel a, wherein the upright side locked aluminium-magnesium-manganese alloy profiled plate is fastened on the aluminium alloy support through mechanical side locking; and a wall surface enclosing plate is fixed on the other structural keel b. The connecting device is characterized in that a side sealing water diversion pressure strip is fastenedon the upper part of the upright side locked aluminium-magnesium-manganese alloy profiled plate on the aluminium alloy support on the edge of the structural keel a; a side sealing fastener connected with the aluminium alloy support is fastened on the side sealing water diversion pressure strip; the side sealing water diversion pressure strip is connected with a flashing shrunk side; and the flashing shrunk side covers the gap between the structural keel b and the side sealing water diversion pressure strip and is connected with the structural keel b. The connecting device has the beneficial effects of reducing the impact of the environment on the stability of the building roofs, playing a role in buffering the building roof edge positions with bigger stress, improving the firmness and avoiding the following hidden danger: water is leaked or the enclosing plate is lifted by wind.

Description

technical field [0001] The invention relates to a sliding connection device for building roofs. Background technique [0002] Because the general building roof is at a non-constant temperature, there is thermal expansion and contraction deformation, especially for metal panels. The deformation of most of the roof enclosure panels in the building system in the width direction can rely on the overlap in the width direction. Seams can be satisfied, but the length direction is difficult to solve only by the sheet itself. Therefore, the sliding of most roof panels in the length direction needs to be realized by sliding brackets, but the connection at the edge of the roof is usually fixed with self-tapping screws or rivets, so the panels at these positions cannot participate in sliding, and at the edge of the building. All of them are stressed, so problems are more likely to occur in these positions, resulting in damage to the fixation, and there are hidden dangers such as water...

Problems solved by technology

Therefore, the sliding of most roof panels in the length direction needs to be realized by sliding brackets, but the connection at the edge of the roof is usually fixed with self-tapping screws or rivets, so the panels at these positions cannot participate in sliding, and at the edge of the building. All of them are stressed, so problems are more likely to occur in these positions, resulting in damage to the fixation, and there are hidden dangers such as water leakage or enclosure panels being lifted by the wind.
