Embodiment Construction

[0032] The present invention will be further described in detail below in conjunction with the accompanying drawings, so that those skilled in the art can implement it with reference to the description.

[0033] The invention discloses a construction method for a waterproof and heat-preserving roof. figure 1 As shown, the method includes at least the following steps:

[0034] Spray polyurethane rigid foam waterproof insulation layer 2 on the roof panel 1.

[0035] The construction process of the thermal insulation and waterproof roof in the prior art is as follows: lay extruded polystyrene board with a thickness of 80 mm on the roof panel; then lay a waterproof layer; lay DS mortar with a thickness of 20 mm as a leveling layer; Concrete is used as the slope layer with a slope value of 2%; finally, C20 fine stone concrete is used as the roof surface layer.

[0036] In the present invention, directly spray polyurethane rigid foam waterproof insulation layer 2 on the roof panel...

Abstract

The invention provides a construction method of a waterproof heat preservation roof. The construction method comprises the steps that firstly, a polyurethane hard foam waterproof heat preservation material is sprayed to a reinforced concrete roof plate; secondly, before the polyurethane hard foam waterproof heat preservation material is foamed and cured, an extruded plastic polyphenyl heat preservation plate with the thickness being gradually decreased is laid onto the polyurethane material in the sloping direction; and thirdly, another polyurethane hard foam waterproof heat preservation material is sprayed onto the extruded plastic polyphenyl heat preservation plate, and a sloping layer with the gradient being 2% is formed. According to the method, the polyurethane waterproof heat preservation layer is directly sprayed onto the roof plate, the heat preservation performance and the waterproof performance of polyurethane are utilized, and the heat preservation layer, the waterproof layer and the sloping / leveling layer of the roof are integrated into a whole. The construction method of the waterproof heat preservation roof is simple, fast to implement and low in construction cost.

Description

technical field [0001] The invention belongs to the field of roofs, and in particular relates to a construction method of a waterproof and thermal insulation roof. Background technique [0002] At present, the roof structure made by the construction industry, that is, the roof structure of the house, is that the insulation layer is located above the reinforced concrete structure layer, and then the cement mortar protective layer is made, and the waterproof layer is made on the protective layer. This structure is not only cumbersome to construct, but also wastes materials due to cross-operation, slow construction speed, and increases a large roof load; moreover, this structure does not take into account the comprehensive utilization of the two functions of waterproofing and heat insulation. The cross-effects between them are very unsatisfactory. Moreover, in the existing light-steel roofing construction technology, steel plates are usually overlapped as a waterproof layer. W...
