Description

A roof engineering system structure

technical field

The utility model relates to a building roof, in particular to a roof engineering system structure.

Background technique

The traditional roof structure is generally to set up a slope layer, an air barrier layer, an insulation layer, a waterproof layer, a waterproof protective layer, and a surface layer on the roof concrete in sequence. Due to the limitations of the material itself and the construction method, the existing roof structure usually has the following disadvantages:

1. The overall system scheme of roof waterproofing and thermal insulation is prone to water leakage and water channeling: the structure of the roof structure is complex, the construction level of the workers is uneven, and the construction technology is complicated. The slope layer, waterproof layer, insulation layer, and protective layer are all constructed separately. The cross-operation between different processes is easy to affect and damage each other, and the possible incompatibility between different materials makes it difficult to guarantee the construction quality and reliability, resulting in frequent quality problems or hidden dangers in buildings.

2. Long construction period for roof waterproofing and thermal insulation: Due to the complicated construction process, the construction period and high cost required for roof waterproofing and thermal insulation are long, especially the slope layer that is directly compounded with the structural layer needs to wait for the final setting before proceeding to the next step of construction, which is time-consuming At the same time, the upper part of the slope-seeking layer is constructed with a multi-layer composite structure, and the layer load is heavy and easy to crack.

3. Roof waterproofing and heat preservation cannot meet the requirements of environmental protection and energy saving: the isolation film of the current waterproof membrane SBS is recycled material, which reduces the function of the waterproof layer of the membrane. At the same time, SBS is also mixed with a certain amount of waste rubber powder, which affects Modified asphalt quality, and increased pollution to the environment. Generally, insulation boards or granular insulation materials are used for roof insulation. When insulation boards or insulation granular materials are used as the insulation layer, a complete insulation surface cannot be formed, and the expected insulation effect cannot be achieved. varying degrees of influence.

4. Roof waterproofing and heat preservation cannot be seamless and integral: polyester tires use short fibers and are bonded with starch glue, which makes it difficult to bond with the base layer and the lap joints.

5. The polyurethane rigid foam insulation material layer on the foamed cement slope finding layer cannot achieve the effect of direct point-to-point repair of leaking water: the waterproof layer is set in the middle of the roof structure layer, and the leakage points on the surface of the structure are often not real The leak point cannot be accurately located, and the structural layer needs to be substantially repaired, and the construction is cumbersome and the workload is heavy.

Utility model content

The purpose of this utility model is to provide a roof engineering system structure, to solve the problems existing in the existing roof structure and construction methods, such as easy leakage and water channeling, long construction period, failure to meet the requirements of environmental protection and energy saving, and failure to achieve no joints Integrity and technical issues that cannot be patched ad hoc.

In order to achieve the above object, the utility model adopts the following technical solutions:

The sprayed thermal insulation and waterproof layer is a hard foam polyurethane layer;

The cast-in-place thermal insulation slope-finding layer is a foam concrete layer;

The sprayed waterproof protective surface layer is a polymer cement anti-crack waterproof mortar layer.

The roof engineering system of the present utility model is an existing integral roof engineering system, which achieves the energy-saving and environmental protection effects required by the state. The main waterproof layer is directly sprayed with waterproof paint on the structural roof, which can be better combined with the structural layer. Spray hard Polyurethane foam is the thermal insulation and waterproof layer, which protects the waterproof layer from damage and slows down the aging of the waterproof layer due to external climate changes, reaching the first-class waterproof standard. The cast-in-place foam concrete is the thermal insulation slope layer; spray polymer cement to resist cracking and waterproof Mortar is the protective layer.

Each layer of the utility model can be used as a waterproof layer to improve the waterproof and heat-preservation effect of the roof and the protection effect of the finished product; the heat-insulation layer has no joints and gaps, good heat insulation and heat preservation, and the steps of plate cutting and installation are omitted. Spraying rigid polyurethane foam, cast-in-place foam concrete, and spraying polymer cement anti-cracking waterproof mortar can all be used as insulation layers. Even if one layer fails, the rest of the structure can also protect the roof well. The compatibility and complementarity between materials can ensure the integrity of the waterproof layer and thermal insulation layer, and reduce the damage to the waterproof layer and thermal insulation layer due to changes in external natural factors. And all structures are mechanized construction, no joints and no leakage.
