Referring to fig. 1 and 3, as a specific implementation manner of the embodiment of the present invention, the combining groove 310 is a dovetail groove. When the end face mortar layer 600 is smeared, the mortar can smoothly enter a dovetail groove. Because the width of the outer opening of the dovetail groove is smaller than the width of the inner cavity, that is, the dimension value of the opening of the dovetail groove in the vertical direction is smaller than the dimension value of the inner cavity of the dovetail groove in the vertical direction, after the end face mortar layer 600 is solidified, the end face mortar layer 600 is difficult to be separated from the dovetail groove, a firm connection relation can be formed between the end face mortar layer 600 and the dovetail groove, and the end face mortar layer 600 is prevented from falling off.

Furthermore, according to the thickness of the heat-insulating layer 300, the dovetail grooves can be arranged in two or three ways in the up-down direction, so that the firm combination between the end face mortar layer 600 and the heat-insulating layer 300 is ensured, and the overall heat-insulating performance of the whole roof structure is further ensured.

Referring to fig. 1 and 3, the insulating layer 300 is an extruded polystyrene board, and a waterproof adhesive layer 320 is disposed between two adjacent extruded polystyrene boards. Because the both sides at the ridge have the inclination that is used for the drainage respectively, so the extruded polystyrene board of both sides is the form of components of a whole that can function independently, needs to realize connecting in ridge department, in order to avoid producing thermal circulation in the gap between the extruded polystyrene board, so use waterproof adhesive layer 320 to connect here, improve the heat preservation effect on the one hand, on the other hand also makes gap department have better waterproof performance, improves roofing structure's wholeness.

Furthermore, because in the length direction of the ridge, a plurality of extruded polystyrene boards need to be spliced, two adjacent extruded polystyrene boards also need to be connected through the waterproof adhesive layer 320, so that the integrity of the whole heat-insulating layer 300 is realized, and the double effects of heat insulation and water resistance are ensured.

As a specific implementation of the embodiment of the present invention, the waterproof layer 500 includes a spraying quick-setting rubber asphalt waterproof layer and a forming non-curing rubber asphalt waterproof layer 500 which is arranged above the spraying quick-setting rubber asphalt waterproof layer and is bonded with the spraying quick-setting rubber asphalt waterproof layer. The spray-coating quick-setting rubber asphalt water-proofing paint is made up by adopting special process and compounding superfine, suspension and micro-emulsion type modified anionic emulsified asphalt and synthetic high-molecular polymer, then mixing them with special solidifying agent and making them react so as to obtain the invented product with excellent water-proofing, seepage-proofing, anticorrosion and protective properties. The main components of the modified emulsified rubber asphalt are more than 2 kinds of high-performance modified emulsified rubber asphalt and a chemical coagulation accelerating catalyst, and the modified emulsified rubber asphalt has a double-component system with the characteristic of rapid initial setting and solidification.

The non-solidified rubber asphalt waterproof paint is prepared by using rubber, asphalt and softening oil as main components and adding temperature controller and stuffing and mixing.
