Problems solved by technology

However, it has no anti-"cold bridge" related structure, which cannot meet the production requirements for high-demand workshops, and the generation of roof condensate will hinder normal production.

Embodiment 1

[0023] Example 1: Such as figure 1 As shown, a steel structure roof waterproof and thermal insulation structure, the roof is sloped. The steel structure is mainly composed of steel beam 9 and purlin 1. The upper end of the purlin 1 is laid with a roof top plate 21, and the lower end of the purlin 1 is a roof bottom plate 22. Two insulation layers are provided between the roof top plate 21 and the purlin 1, which are an upper insulation layer 31 and a lower insulation layer 32, respectively. The upper insulation layer 31 and the lower insulation layer 32 are separated by a supporting inner purlin 4. The supporting inner purlin 4 and the purlin 1 are arranged correspondingly, and the purlin 1 is used as the supporting base. The supporting inner purlin 4 separates the upper thermal insulation layer 31 and the lower thermal insulation layer 32 to form a closed thermal insulation cavity to prevent the "cold bridge" phenomenon. From top to bottom, a layered structure of the roof t...

Embodiment 2

[0028] Embodiment 2: The difference from Embodiment 1 is that the upper insulation layer 31 is a glass wool board layer with a thickness of 80 mm, and the lower insulation layer 32 is a glass wool board layer with a thickness of 50 mm. The insulating cushion layer 5 is a polystyrene board layer with a thickness of 20 mm.

Embodiment 3

[0029] Embodiment 3: The difference from Embodiment 1 is that the upper insulation layer 31 is a glass wool board layer with a thickness of 100 mm, and the lower insulation layer 32 is a glass wool board layer with a thickness of 30 mm. The insulating cushion layer 5 is a polystyrene board layer with a thickness of 30 mm.

Abstract

The invention discloses a waterproof heat insulation structure for a steel-structure roof. The waterproof heat insulation structure comprises a steel beam, a purline, a roof top plate and a roof bottom plate, wherein the roof top plate and the roof bottom plate are laid at the upper and lower ends of the purline respectively. An upper heat insulation layer and a lower heat insulation layer are arranged between the roof top plate and the purline and partitioned by an inner supporting purlin to form a heat insulation cavity, and the inner supporting purlin is arranged between the upper heat insulation layer and the lower heat insulation layer. A first heat insulation cushion layer is arranged between the inner supporting purlin and the upper heat insulation layer, a second heat insulation cushion layer is arranged between the inner supporting purlin and the lower heat insulation layer, the inner supporting purlin and the purline are arrayed oppositely in position, and the inner supporting purlin is fixed onto the purline. The waterproof heat insulation structure for the steel-structure roof has the advantages that 'cold bridge' can be avoided to prevent condensate water in the roof; further, the roof has excellent waterproof performance.

Description

Technical field [0001] The invention relates to a building steel structure roof structure, in particular to a steel structure roof waterproof and thermal insulation structure. Background technique [0002] At present, the general steel structure building roof basically installs a bottom plate on the underside of the purlin, adds an insulation layer on the upper side of the purlin, and then lays a roof panel on the insulation layer to achieve the insulation function. This structure is relatively simple and easy to implement. However, in winter, especially in the north, due to the production requirements, the factory room maintains a certain humidity and temperature. At this time, the temperature difference between indoor and outdoor is large. Condensed water will appear on the side of the roof floor close to the room, forming a "cold bridge" phenomenon. [0003] For example, the Chinese patent publication number: CN 203475728U, the patent document published on March 12, 2014, discl...
