The traditional technology comprises pre-embedding, a waterproof layer, a waterproof protective layer, a heat preservation adhesive layer, a fine stone concrete layer on the heat preservation layer, a reinforcing mesh and the like. The waterproof layer plays an important role in the waterproof structure, but the waterproof layer is arranged on the outermost layer of the waterproof structure, is exposed to the sun for a long time in summer and is corroded by freezing, rain and snow in winter, and the waterproof layer is easy to age, so that the waterproof effect is poor, and the service life of the waterproof structure is shortened. The heat-insulating layer is mainly divided into three main categories, namely a loose material heat-insulating layer, a plate-shaped material heat-insulating layer and an integral heat-insulating layer. But because of the inherent defects of the materials, the roof is not suitable for people, the construction process is complex, the construction period is relatively long, the waterproof layer is frozen in winter and sunned in summer, the durability is poor, and the like. And the material and labor cost, the scaffold lease cost and other related costs of the traditional process are huge and the cost is too high.

Detailed Description

The invention is described in further detail below with reference to the figures and the embodiments.

As shown in fig. 1, a tile roof waterproof heat insulation structure, including insulating layer 1, waterproof layer 2 and roof tile 3 that set gradually from bottom to top, insulating layer 1 is the heat insulating board, evenly spreads and pastes on the sloping roof, waterproof layer 2 is laid by a plurality of wave form pitch waterproof boards and is formed, roof tile 3 connects on waterproof layer 2 through water guiding strip 6 and battens 4, water guiding strip 6 and battens 4 are heat insulation structure, fix battens 4, waterproof layer 2 and insulating layer 1 on the sloping roof through expansion bolts 5.

Preferably, after the control line is formed by the thermal insulation layer, the plurality of corrugated asphalt waterproof boards are laid from bottom to top from the eave and are laid along 1 corrugated in the transverse lap joint, and the upper row and the lower row of longitudinal joints are staggered by 1/3-1/2.

Preferably, the expansion bolts 5 are driven at the wave crests of the corrugated asphalt-waterproof sheet. Such an arrangement does not affect the "channels" of the troughs, avoiding the expansion bolts 5 from affecting the air circulation and excluding the water flow.

Preferably, the head of the expansion bolt 5 is sealed with a waterproof sealant. Due to the arrangement, water is prevented from flowing in from the nail cap of the expansion bolt 5, and the waterproof performance is ensured.

Preferably, the nodes of gable walls, vertical walls, ridges and the like are reinforced by waterproof rolls. The arrangement ensures the waterproof performance of the nodes such as gable walls, vertical walls, roof ridges and the like.

The corrugated asphalt waterproof board is laid from bottom to top from the eave after the control line is bounced after the thermal insulation layer 1 is constructed by adopting a dry laying method, and the upper board is ensured to press down the block board.

When the corrugated asphalt waterproof board is laid, the corrugated asphalt waterproof board is overlapped by 100mm along the water direction, 1 wave form is overlapped along the transverse direction, and the widths of the upper and lower 2 rows of longitudinal seams are staggered by 1/3-1/2 sheets. When the plate is cut, an electric cutting tool needs to be used for elastic wire cutting.

Bolt holes are punched in the battens 4 in advance, the battens 4 and the heat insulation layer 1 are directly fixed to a pitched roof structure layer through expansion bolts 5 after the corrugated asphalt waterproof board is laid, the expansion bolts 5 enter the pitched roof structure layer by 40-50 mm, all the expansion bolts 5 need to be punched at wave crests of the corrugated asphalt waterproof board, and the nail caps of the expansion bolts 5 are sealed by waterproof sealant. If the hole position of the expansion bolt 5 is deviated, the hole is required to be re-punched at the adjacent wave crest, and the deviated hole is sealed.
