Problems solved by technology

It can effectively reduce the adverse effects of environmental factors on it, and avoid thermal stress, ultraviolet rays and other factors from damaging the waterproof layer. Large amount of materials, high construction cost and poor load bearing
In addition, the rainwater on the surface layer will continuously seep into the insulation layer and cannot be discharged, forming the phenomenon of "internal water accumulation" and cannot be discharged, which seriously affects the quality

Embodiment Construction

[0022] A construction method for an inverted roof, comprising a constructed structural layer 1, the construction steps of which are as follows:

[0023] (1) carry out slope finding setting to the outer surface of structure layer 1, make its slope be 2-3%;

[0024] (2) V-shaped drains 6 arranged from the center to the surroundings are spaced apart on the outer surface of the structural layer 1, and built-in drains 7 arranged along its length are arranged at the bottom of the V-shaped drains 6; A drainage hole 8 is reserved on the structural layer 1 between the glyph drainage ditch 6, so that the depth of the drainage hole 8 is not greater than one-third of the thickness of the structural layer 1, and the depth of the V-shaped drainage ditch 6 is greater than the depth of the drainage hole 8; The bottom of the drainage hole 8 is communicated with the built-in drainage pipe 7 through the pipeline 9;

[0025] (3) Clean up the sundries and garbage on the surface, and level off and...

Abstract

The invention discloses a construction method for an inverted roof, which comprises the construction of a constructed structural layer, setting slope finding on the outer surface of the structural layer so that the slope is 2-3%; setting a V-shaped drainage ditch, built-in drainage pipes and Drainage holes; cleaning of layers; application of first waterproof coating; laying of insulation; pouring of protective layer; second application of waterproof coating in V-shaped drainage ditch; laying of natural stones or precast concrete blocks or loose paving pebble. The whole system achieves the best thermal insulation effect, and the water on the roof is discharged smoothly, so there will be no water accumulation on the roof, which greatly reduces the hidden danger of leakage and optimizes the waterproof performance of the roof.

Description

technical field [0001] The invention relates to a building construction method, in particular to a construction method for an inverted roof. Background technique [0002] The traditional roof structure is mostly a vertical roof, and its structure is generally that the heat insulation layer is under the waterproof layer. The materials for the heat insulation layer are generally perlite, cement polystyrene board, aerated concrete, ceramsite concrete, polystyrene Ethylene sheet (EPS) and other materials. Because these materials generally have the common problem of high water absorption rate, which will reduce the thermal insulation performance and cannot meet the requirements of heat insulation, so a waterproof layer is set on it to prevent the infiltration of water, so as to ensure the dryness of the heat insulation layer. to heat insulation. In addition, because the waterproof layer is directly exposed to the air, it is easily affected by the environment, so its material an...
