Roof heat preservation system structure

Abstract

The invention aims to disclose a roof heat preservation system structure, which comprises a reinforced concrete base layer and a mortar leveling layer laid on the reinforced concrete base layer, wherein pay-off embedded steel bars, a waterproof layer, a heat preservation layer, a protective layer and counter battens are sequentially arranged on the mortar leveling layer, roof battens are laid on the counter battens, hanging roof tiles are arranged on the roof battens, the counter battens are fixed on the protective layer through a metal bar structure and are levelled, and the protective layeris a mortar protective layer or an easy-to-coil material covering protective layer. Compared with the prior art, the roof heat preservation system structure has good waterproof effect, is suitable forconstruction of various modeling slope roofs, has good heat preservation performance, less wet operation and strong air convection, has effects of energy conservation and environment protection, greatly reduces the use of non-renewable or less-renewable resources, is an advocacy of green building engineering and achieves the objective of the present invention.

Description

technical field [0001] The invention relates to a roof structure, in particular to a roof insulation system structure. Background technique [0002] There are two main types of sloping roofs in existing construction projects. Although they are widely used, they both have relatively large defects. Either the resource consumption is relatively large, which is contrary to the environmental protection of the construction industry currently advocated, or a series of construction quality such as water leakage are prone to occur. question. [0003] One is to make a waterproof layer on the leveling layer, a thermal insulation layer and a reinforced concrete protective layer on the waterproof layer, and a water strip on the protective layer perpendicular to the direction of the roof ridge. . However, its disadvantages are: [0004] 1. A lot of labor is needed on the waterproof layer. After the waterproof layer is completed, there are many subsequent construction steps, which will ...

AI Technical Summary

Problems solved by technology

[0004] 1. A lot of labor is required on the waterproof layer. After the waterproof layer is completed, there will be many follow-up construction steps, which will inevitably damage the waterproof layer, and it is not easy to find after the waterproof layer is damaged. Leakage will only be found after the roof is completed, so that the leak point is not easy to find , and it is necessary to remove the reinforced concrete protective layer, thermal insulation layer and roof tiles during the repair, the workload is relatively large and the maintenance is difficult;

[0005] 2. It needs to use a lot of steel bars and concrete. As we all know, these two materials are not environmentally friendly materials, and they are also high-energy-consuming materials. They have relatively large environmental pollution and run counter to the concept of building environmental protection.

[0007] 1. The roof is very prone to water leakage, because the water strip is directly nailed to the waterproof material. Although the SAB self-adhesive coil is resistant to nail penetration and self-closing to the nail penetration material, there will be a lot of construction in the future for the waterproof layer. Steps, the construction personnel step on the water strips in large numbers, which will cause the water strips to slip, which will inevitably tear the waterproof material and cause permanent irreversible damage;

[0008] 2. The waterproof material of SAB itself has relatively large requirements on the construction environment. Humidity and low temperature will cause the waterproof material to be bonded to the leveling layer, waterproof material and waterproof material. Therefore, the construction time and environmental conditions are very demanding, which will inevitably lead to Many projects cannot be adopted;

[0009] 3. Embedding thermal insulation materials between the water strips will inevitably lead to an increase in the amount of water strips. Generally, wood is used for the water strips. As we all know, the increase in the amount of wood will inevitably aggravate the damage to the environment, which has a fatal weakness in environmental protection. At the same time, the insulation material is embedded between the water strips, which will cause the insulation material to fall off due to loose fixation. At the same time, it is easy to generate a cold bridge, which will increase the amount of indoor heating, which will inevitably increase environmental pollution; in addition, the insulation material has no protection. Measures to make it directly in contact with the air will accelerate the aging of the insulation material and reduce the service life of the insulation material;

[0010] 4. The water strip is mainly fixed on the roof structure by nails. We all know that the weight of the roof tile is relatively large. When the slope is relatively large, it is easy to cause the overall landslide of the roof project, resulting in waste of rework
