Connection structure of lower end of double-wave daylighting band joint and installation method thereof

Abstract

The invention provides a connection structure of the lower end of a double-wave daylighting band joint and an installation method thereof, stable sealing connection at the junction of the lower end ofthe double-wave daylighting band joint is realized, and the protection effect on rainwater flowing down from the top of a slope is good. The installation method includes the steps that an overturnedthermal insulation cotton veneer is fixed at the periphery of a hole of a daylighting band at a roof by using a cotton pressing piece; a daylighting band support is installed at the roof purlin position at the edge of the lower end of the hole of the daylighting band; a liner plate is installed at the edge of the lower end of the hole for lap joint; a lower end metal roofing board on the lower side of the hole of the daylighting band is laid; cement gum at the lap joint position is paved; the double-wave daylighting band is installed on the lower end metal roofing board to cover the hole of the daylighting band; a lower end saddle pad fastener is installed on the double-wave daylighting band; a stainless steel trim strip is installed at the overlapping joint of the double-wave daylightingband and the edge of the lower end of the hole; a right side metal roofing board of the daylighting band is installed; and the metal roofing boards are overlocked.

Description

technical field [0001] The invention relates to the field of building steel structures, in particular to a connection structure at the lower end of nodes of a double-wave daylighting belt and an installation method thereof. Background technique [0002] At present, many factories adopt the form of steel structure. The characteristics of steel structure factory buildings are as follows: 1. Steel structure buildings are light in weight, high in strength and large in span; 2. The construction period of steel structure buildings is short, which reduces investment costs accordingly; 3. Fire resistance of steel structure buildings High, strong corrosion resistance; 4. The steel structure building is easy to move, and the recycling is pollution-free. [0003] figure 1 It is a schematic diagram of a steel structure factory building, such as figure 1 As shown, the top of the factory building is a metal roof 101 with a certain slope extending obliquely to the left and right sides, t...

Problems solved by technology

Therefore, on the sloping roof, it is very difficult to connect the lighting belt and the roof panel, which often causes water leakage. In order to prevent water leakage and ventilation, the existing technology will use a large amount of sealant and waterproof paint to seal, resulting in abrupt appearance, waste of materials and The waterproof effect is not ideal. Therefore, the connection and sealing problem between the lighting belt and the roof panel is a problem to be solved
