Description

Technical Field

[0001] The utility model relates to the technical field of roof waterproofing, in particular to an inverted building roof waterproofing structure. Background Art

[0002] Modern building roofs often leak due to differences in materials and construction workers, and the leaks are hard to find. There are few options for repairs, either injections or adding surface waterproofing, which do not meet the original design requirements, and the service life is seriously reduced and unreliable. Demolition and reconstruction cannot afford the high cost, and the property management level cannot control the quality of the project. The roof leaks day by day. In addition, the roof is a resource. Due to the fear of roof leakage, today's roofs are often afraid to increase the use of functions.

[0003] Due to the differences in the technical level of construction workers, the existing roof waterproofing technology is often costly and has certain limitations, and leakage still exists. In addition, the "plaster" waterproofing treatment will reduce the service life of the original building structure and cannot fundamentally solve the roof waterproofing problem.

[0004] Therefore, a kind of building roof waterproof structure needs to be studied urgently. Utility Model Content

[0016] In order to make the purpose, technical scheme and advantages of the embodiments of the utility model clearer, the technical scheme in the embodiments of the utility model will be clearly and completely described below in conjunction with the drawings in the embodiments of the utility model. Obviously, the described embodiments are part of the embodiments of the utility model, not all of the embodiments. Generally, the components of the embodiments of the utility model described and shown in the drawings here can be arranged and designed in various different configurations.

[0017] In the description of the embodiments of the present utility model, it should be noted that if the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inside", "outside", etc. indicate an orientation or position relationship based on the orientation or position relationship shown in the accompanying drawings, or the orientation or position relationship in which the utility model product is usually placed when in use, it is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present utility model. In addition, the terms "first", "second", "third", etc. are only used to distinguish the description, and cannot be understood as indicating or implying relative importance.

[0018] In addition, the terms "horizontal", "vertical", "overhanging" and the like do not mean that the components must be absolutely horizontal or overhanging, but can be slightly tilted. For example, "horizontal" only means that its direction is more horizontal than "vertical", and does not mean that the structure must be completely horizontal, but can be slightly tilted.

[0019] In the description of the embodiments of the present invention, "multiple" means at least 2.

[0020] In the description of the embodiments of the present utility model, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0021] In conjunction with the accompanying drawings, a building roof waterproof structure includes, from bottom to top, a concrete floor layer 1, a waterproof mortar repair layer 2, a waterproof layer 3, an insulation layer 4 and a concrete surface layer 5; the concrete surface layer 5 is not provided with a slope.

[0022] The waterproof layer 3 is a waterproof coiled material. The thermal insulation layer 4 is an extruded polystyrene thermal insulation board.

[0023] The thickness of the concrete surface layer 5 is 60-80 mm.

[0024] The upper end surface of the concrete surface layer 5 is provided with a water guide groove.

[0025] The utility model is implemented in the following steps:

[0026] 1) Cleaning and polishing: clean the original structural roof and polish the cleaned original structural roof;

[0027] 2) Repair and detail treatment: Use waterproof mortar to repair leaks and perform detail treatment;

[0028] 3) Waterproof membrane construction: Lay waterproof membrane construction according to building specifications and design requirements;

[0029] 4) Insulation layer construction: Apply waterproof coating on the waterproof membrane and bond the extruded polystyrene insulation board, and carry out construction in accordance with energy-saving design requirements;

[0030] 5) Surface layer construction: Pour 60-80mm thick concrete surface layer without slope, and press or cut water channels according to needs.

[0031] The utility model eliminates the building slope, which is based on the progress of modern waterproof materials. The reliability of waterproof materials is very strong. The original building slope can only play a water guiding role for a short time after the water stops, which is not very helpful for the waterproof system. Although the water guiding effect of the horizontal roof is reduced (may be slower), there may be some water accumulation (which can be solved by surface grooving), but because the drainage ditch is reliable, the roof drainage function is not reduced.

[0032] Since the slope is eliminated, the roof construction method is simplified, the parapet height is controllable, the upward waterproof height is unified, and it is easy to manage; the construction is convenient, maintenance is simple, and the use function is flexible. The purpose of setting the groove is to solve the local water accumulation caused by construction deviation, and it is set according to the shape and size of the roof.

[0033] Extruded polystyrene insulation boards are bonded with waterproof coatings to enhance waterproofing and prevent frost damage.

[0034] Compared with the commonly used 40mm thick concrete, 60-80mm thick concrete can reduce cracks and improve protection. The actual thickness can be adjusted according to the upper purpose.

[0035] The utility model meets the requirements of inverted roof, the waterproofing is integrated with the structure, the reliability is enhanced, the leakage point is easy to find, the maintenance is convenient, and the original system requirements are met after maintenance. The service life of the waterproof material is extended due to the protection of the upper concrete.

[0036] The upper concrete does not participate in waterproofing and is horizontal. Installing equipment on the roof and increasing the use functions can reduce concerns and expand the use functions of the roof.

[0037] There is thermal insulation material between the waterproof material and the concrete surface layer, which reduces the chance of damage to the waterproof layer.

[0038] Due to differences in construction personnel, a small amount of leakage is inevitable during the process. This system provides a convenient maintenance method to improve the waterproof system in subsequent maintenance, rather than an emergency measure of applying a plaster to reduce the service life of the original system.

[0039] The main cause of roof leakage is construction, and the possibility of repair is very high. This solution can greatly reduce the scope of repair, and the system after repair is consistent with the design, and the garbage generated by repair is greatly reduced, which actually plays a role in reducing emissions. Both construction and repair can reduce material consumption to a minimum, which meets the requirements of a low-carbon economy.

[0040] Due to the low maintenance cost and convenience of this system, a ten-year warranty can be provided, thus increasing user satisfaction.

[0041] The above description of the utility model and its implementation methods is not restrictive. The drawings show only one implementation method of the utility model, and the actual structure is not limited thereto. In short, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the invention of the utility model, they should all fall within the protection scope of the utility model.
