Abstract

The utility model provides an inverted type waterproof roof which comprises a structural layer which is arranged on a rooftop. A leveling layer, a combination layer, a waterproof layer, a heat preservation layer and a protective layer are sequentially and outwards arranged on the structural layer in laying mode. The inverted type waterproof roof is simple in construction, low in cost and convenient to construct and maintain. The waterproof layer is arranged below the protective layer and the heat preservation layer, so that the phenomenon that factors, such as thermal stress, ultraviolet rays and outer force damage, generate negative influence on the waterproof layer is avoided, so that the waterproof layer is not easily damaged, and therefore problems, like rooftop leaking, are solved. Service life of the roof is effectively prolonged, and heat preservation and thermal insulation effect of the roof is strengthened.

Description

An inverted waterproof roof

technical field

The utility model belongs to the technical field of building buildings and relates to a building roof, in particular to an inverted waterproof roof.

Background technique

The traditional roof insulation structure is generally to place insulation boards on the roof panels, and then set a waterproof layer on the insulation boards. The roof insulation structure of this structure, because the waterproof layer is exposed to the outside, is damaged by sunlight, high and low temperature or external force. The waterproof layer is easily aged, cracked and damaged, causing water leakage on the roof and affecting the service life and thermal insulation effect of the roof.

Contents of the invention

The utility model aims at the situation that the existing roof waterproof layer is exposed, which makes the roof prone to leakage, and proposes an inverted waterproof roof with simple structure, convenient construction and durability.

In order to solve the above-mentioned technical problems, the utility model adopts the following technical solutions to achieve:

An inverted waterproof roof includes a structural layer arranged on the roof, and a leveling layer, a bonding layer, a waterproof layer, a thermal insulation layer and a protective layer are sequentially laid outward from the structural layer.

Preferably, at least one layer of fiber fabric is laid between the insulation layer and the protection layer to prevent the protection layer from piercing or corroding the insulation layer.

Further, the protective layer is preferably laid by one of reinforced fine stone concrete, pebbles, natural stones, and prefabricated concrete blocks.

For the insulation layer, two structural designs can be adopted:

One is to lay extruded polystyrene thermal insulation boards to form the thermal insulation layer. At this time, the thermal insulation layer is preferably directly pasted on the waterproof layer through an adhesive.

The other is to use foamed polystyrene cement heat insulation bricks to lay the heat insulation layer. At this time, the thermal insulation layer is preferably directly pasted on the waterproof layer through cement mortar.

Further, the structural layer is preferably made of reinforced concrete, and the roof slope adopts a structural slope of 3%, which can save the laying of the slope layer to reduce the weight of the roof itself.

Compared with the prior art, the advantages and positive effects of the utility model are: the inverted waterproof roof of the utility model has a simple structure, low cost, and is convenient for construction and maintenance, and the waterproof layer is placed under the protective layer and the thermal insulation layer, It can avoid the adverse effects of thermal stress, ultraviolet rays and external force damage on the waterproof layer, making the waterproof layer less susceptible to damage, avoiding roof leakage and other problems, effectively prolonging the service life of the roof and strengthening the insulation of the roof. heat effect.

After reading the specific implementation of the utility model in conjunction with the accompanying drawings, other features and advantages of the utility model will become clearer.

Description of drawings

Fig. 1 is a structural schematic diagram of an embodiment of an inverted waterproof roof proposed by the utility model.

Detailed ways

Specific embodiments of the present utility model are described in detail below in conjunction with the accompanying drawings.

In this embodiment, in order to solve the problem that the existing roof waterproof layer is exposed and the roof is prone to leakage, an inverted waterproof roof is designed, as shown in Figure 1, which mainly includes a structural layer 6, a leveling layer 5, and a bonding layer 4. Waterproof layer 3, insulation layer 2 and protective layer 1 and other components. Wherein, the structural layer 6 is located at the bottom of the inverted waterproof roof, installed on the top surface of the house, and the leveling layer 5, the bonding layer 4, the waterproof layer 3, the thermal insulation layer 2 and the protective layer are sequentially laid outward from the structural layer 6. Layer 1.

For the specific construction process of the inverted waterproof roof, the following steps can be adopted: first, pour reinforced concrete on the roof to form the structural layer 6, and adopt the treatment method of 3% structural slope to make the roof form an inclined plane, thus saving The slope layer is laid to achieve the design purpose of reducing the weight of the roof itself. Secondly, apply cement mortar on the structural layer 6 for leveling, the mixing ratio of the cement mortar is preferably 1:3, to form the leveling layer 5 . The thickness of the leveling layer 5 is preferably designed to be 20mm. Then, brush the cold base oil twice on the leveling layer 5 to form the bonding layer 4 . The use of the cold base oil can increase the adhesion of the waterproof layer 3, and at the same time prevent the water vapor from below from penetrating up, reducing the bubbling problem of the waterproof layer 3. Next, the waterproof layer 3 is laid on the bonding layer 4, and the waterproof layer 3 is preferably made of high polymer modified asphalt waterproofing membrane to achieve better adhesion with the cold base oil. Then, lay the thermal insulation layer 2 on the waterproof layer 3, and lay at least one layer of puncture-resistant and corrosion-resistant fiber fabric above the thermal insulation layer 2, to prevent the protective layer 1 from causing damage to the thermal insulation layer 2. Finally, the protective layer 1 is laid on the fiber fabric to complete the laying of the inverted waterproof roof.

For the specific laying method between the thermal insulation layer 2 and the protective layer 1, the present embodiment preferably adopts the following two forms:

First of all, for the insulation layer 2, the following two materials are preferably laid to form:

One is: using extruded polystyrene thermal insulation boards with high compression resistance and low water absorption to form the thermal insulation layer 2, the thickness of which is preferably 60mm, and bonded to the waterproof layer 3 by professional adhesives. Then the protective layer 1 is laid on the insulation layer 2 .

The second is: use foamed polystyrene cement heat insulation bricks to lay the heat insulation layer 2, and bond it to the waterproof layer 3 through cement mortar, and then lay the protective layer 1 on the heat insulation layer 2.

Secondly, for the protective layer 1, the following formation methods are preferably adopted:

If there are people on the roof who need to bear the weight of the people, preferably pour fine stone concrete with reinforcement on the thermal insulation layer 2 to form the protective layer 1 . If it needs to be beautiful, cement mortar powder finish, clinker bricks or square bricks can be further laid on the surface of the protective layer 1 . For roofs that are only used for maintenance or fire protection, it is preferable to lay natural stones or prefabricated concrete on the thermal insulation layer 2 to form the protective layer 1. If there is no requirement for standing people on the roof, then preferably spread pebbles on the thermal insulation layer 2 to form the protective layer 1 . The thickness of the protective layer 1 can be designed at 50 mm, and the diameter of the pebbles is preferably between 20 and 30 mm.

The inverted waterproof roof designed in this embodiment is used on the top of the house. While protecting the waterproof layer and avoiding roof leakage, it can effectively reduce the weight of the roof, reduce the load-bearing requirements for the walls around the house, and improve the thermal insulation of the roof. heat effect.
