Technical Field

The invention relates to a manned roof, in particular to a manned roof composite waterproof system and a construction method of the composite waterproof system.

Background

At present, the commonly used roof waterproof method generally adopts the following two modes: 1. the rigid material waterproof refers to a cement mortar concrete waterproof material with certain permeation resistance prepared by taking cement and sandstone as raw materials or adding a small amount of materials such as additives, high molecular polymers and the like into the cement and sandstone, and adjusting the mixing proportion, inhibiting or reducing the porosity, changing the pore characteristics, increasing the compactness among interfaces of the raw materials and the like; 2. the flexible waterproof material is also called asphalt felt coiled material waterproof, and is a waterproof layer formed by adhering various adhesive materials such as asphalt and the like on a roof structural plate by using a coiled material made of asphalt felt, polyester cloth, glass fiber cloth and the like as a base.

Because there is certain drawback in current waterproof system: due to poor weather resistance, ultraviolet resistance and ageing resistance, the coating can crack and seep water after being exposed for a period of time. Moreover, for the accessible roof, besides normal water resistance, mortar or floor tile protective layers are needed, so that the construction cost and the roof load are increased; if the roof waterproof layer is in case of failure, the maintenance of the waterproof system is difficult and heavy, the maintenance can be carried out after the protective layer, the heat preservation layer, the leveling layer and the waterproof layer are sequentially removed, and a large amount of building wastes generated pollute the environment and cause the waste of manpower and material resources.

In order to achieve the purpose, the invention can adopt the following technical scheme:

the composite waterproof system for the accessible roof comprises a flexible waterproof adhesive layer coated on a base layer, a polymer waterproof coiled material laid on the flexible waterproof adhesive layer and an anti-aging layer coated outside the polymer waterproof coiled material, wherein:

The granularity of the carborundum is 2000-2500 meshes; according to the specification of the grain size and the composition of the GB2477-83 grinding tool, the carborundum consists of metal mineral aggregate with certain grain composition or extremely wear-resistant nonferrous metal aggregate and special additives.

The ratio of the rigid resin to the flexible resin is 6: 4.

The polymer waterproof coiled material used in the invention is a three-layer composite structure which is formed by using polyester filament cloth as a base, impregnating high-molecular polymer emulsion on two surfaces of the base and drying the base.

The invention relates to a construction method of a composite waterproof system for a accessible roof, which comprises the following steps:

(4) keeping the rotating speed at 300rpm, adding the thickening agent and the coloring agent, dispersing for 20 minutes, and then packaging and storing.

The polymer waterproof coiled material 3 used in the invention is a three-layer composite structure which is formed by using polyester filament cloth as a base and soaking high molecular polymer emulsion on two sides and then drying, for example, an LSL (zero leakage) polymer waterproof coiled material can be adopted.

The invention relates to a construction method of a composite waterproof system for a accessible roof, which comprises the following steps:

firstly, finishing the surface of a foundation layer 1 to be laid (in actual construction, if the foundation layer is damaged, loosened or not flat, the cement waterproof mortar is required to be used for finishing), and cleaning and removing floating dust, oil stains and impurities;

second step, on the processed basePopping up powder lines or ink lines on the surface of the layer 1, pre-laying the polymer waterproof coiled material at a preset position, rolling back, spraying flexible waterproof emulsion at the pre-laid position to form a flexible waterproof adhesive layer to ensure the adhesive strength, wherein the spraying amount of the flexible waterproof emulsion is 0.75-1kg/m²The spraying thickness is more than or equal to 1mm (generally 1.2 mm);

The constructed composite waterproofing system is shown in fig. 1.

The finished waterproof system needs to be inspected according to construction technical rules, and if unqualified parts are found, the finished waterproof system needs to be reworked immediately until all projects are qualified.

Compared with the traditional protective layer, the performance comparison of the anti-aging layer in the composite waterproof system for the accessible roof is shown in the following table:

as can be seen from the data in the table: the system has the advantages of lower load, lower price, one-step forming and more convenient later maintenance under the condition of the same area. The system has larger construction area under the condition of the same load, and the area of the system is more than 3 times of that of roof bricks or fine stone concrete under the condition of the same price, so that the surface layer can play a good protection role while the waterproof requirement is met.
