Detailed Description

The preferred embodiments of the present invention will be described in conjunction with the accompanying drawings, and it will be understood that they are presented herein only to illustrate and explain the present invention, and not to limit the present invention.

The roof waterproof and heat insulation structure is more particularly suitable for roof structures with sloping surfaces, i.e. the technology is preferably suitable for roof systems with sloping surfaces.

Referring to fig. 2 to 5, the present roof construction is a roof construction for a sloping roof, and the construction is described in relation to the following sections.

The following description is in a floor-by-floor order of the building construction from bottom to top.

The beam 10 can be a reinforced concrete prefabricated beam or a metal beam so as to meet the requirement of roof strength under the condition of large span. When the cross beam is a metal component, the surface of the metal beam needs to be subjected to anticorrosion treatment, such as spraying of anticorrosion paint.

The reinforced concrete precast slab 20 is made of a thin reinforced concrete slab having a thickness of 3 cm, and is connected to the beam 10 by using a connection bolt, but other connections may be used instead of the bolt connection, for example, by providing a positioning pin. The reinforced concrete precast slab provides sufficient strength to a roofing system.

A thin layer of adhesive mortar 30 is coated on the upper surface of the reinforced concrete precast slab 20. The bonding mortar is used for bonding an upper air exchange layer 40, which adopts corrugated metal plates, and in the air exchange layer, the air exchange layer is formed by splicing two corrugated metal plates, specifically, two plates of the corrugated metal plates are symmetrically laid on the roof in the middle, and the corrugations of the two metal plates are not perpendicular to the direction of the cross beam, nor parallel to the direction of the cross beam, but are arranged in an inclined manner at a certain angle, and the inclined angle is closer to the direction perpendicular to the cross beam part by ninety degrees, that is, the inclined angle which is basically 90 degrees with the roof slope exists, for example, the inclined angle beta in fig. 5 exists at 80 degrees. Two corrugated metal plates are spliced in the middle, and waterproof treatment is carried out at the middle vertical splicing seam, the waterproof treatment mode is that waterproof asphalt or asphalt felt is poured or coated at the splicing seam to carry out local corrosion prevention, a local waterproof corrosion prevention area 41 is formed, and the splicing process of the waterproof corrosion prevention area can refer to the lap joint and splicing style shown in fig. 6 to fig. 8.

A layer of waterproof felt 50 is laid on the ventilation layer 40, and a layer of heat insulation layer 60 is adhered on the felt. Preferably, the heat insulation layer 60 is made of corrugated metal plate, and the specification and type of the corrugated metal plate are the same as those of the air exchange layer, except that the corrugated metal plate in the air exchange layer is adhered in the same direction as the slope of the roof. That is to say, the concave-convex trend of the flute in the corrugated metal plate is consistent with the roof water falling direction, and the arrangement mode is favorable for the anti-leakage and safety performance of a roof system.

A layer of waterproof felt 50' is laid above the heat insulation layer 60, anti-cracking mortar and grid cloth are laid above the felt to form a roof anti-cracking layer 70, and finally, installation and construction of the decorative tile 80 are carried out above the anti-cracking layer according to needs.

That is, in the main body part of the roofing system, from the bottom up, there are the cross beam 10, the reinforced concrete precast slab 20, the adhesive mortar 30, the ventilation layer 40, the waterproof linoleum 50, the thermal insulation layer 60, the waterproof linoleum 50', the anti-cracking layer 70, and the decorative tile 80.

The edge sealing treatment process for the roof system comprises the following steps:

after the main body is constructed, local sealing and water proofing 90 is carried out on the ridge part at the periphery and the top of the roof system, specifically, anti-cracking mortar and gridding cloth are used for finishing and sealing at two horizontal straight edge positions of the roof system, so that the ventilation layer and the heat insulation layer are completely sealed. And a water dripping edge is arranged on the horizontal part, and the part can be paved with waterproof asphalt felt according to the requirement, so that the aim of local waterproofing is achieved. Generally, the water seepage probability of the part is almost zero due to the decorative tile.

In the present embodiment, the roof ridge is waterproofed by performing waterproofing treatment of a plurality of layers of linoleum and emulsified asphalt at the ridge portion, and usually, the linoleum is used to perform overlapping, and particularly, the portions of the left and right slopes are overlapped to form waterproofness. And finally, sealing edges on the ridge by using the special ridge tile to form ridge waterproofing, wherein the possibility of water seepage at the ridge is almost zero.

In this embodiment, when the bevel edge of the side surface of the roof is subjected to waterproof treatment, the ventilation channel in the ventilation layer needs to be kept smooth, specifically, in this embodiment, a ventilation hole 91 is reserved at the bevel edge part and is communicated with the ventilation channel in the ventilation layer 40, that is, the air flow can be ventilated between the ventilation layer and the external atmosphere, and the ventilation channel belongs to the groove part of the corrugated metal plate, that is, the ventilation channel is in a herringbone shape in the roof system, and this structure can prevent rainwater from flowing backwards and upwards and keep the ventilation channel smooth.

The advantage of the structure is not only represented by good fireproof performance (metal and concrete are not inflammable), but also represented by good heat insulation effect, for example, in hot summer, when the roof is exposed to sunlight, the temperature of the top layer (tile part) is higher than 60 ℃, due to the existence of the middle heat insulation layer 60, most of heat is effectively separated, so that the temperature reaching the heat exchange layer is kept at about 40 ℃, and the heat exchange layer is provided with a heat exchange channel, air flow can form microcirculation at the part and take away a small amount of heat, so that after heat exchange, the temperature of the roof is kept at about ambient temperature, for example, the ambient temperature is 30 ℃, the constant temperature of the roof is about 30 ℃, and the arrangement greatly reduces the heat form caused by sunlight exposure.

The utility model discloses have good waterproof, leak protection effect, because the moisture absorption ability of flute technical board is zero basically, so can not have the deformation of foaming thermal insulation material, the fracture problem, especially in the more moist plum rain season in south, the implementation of this embodiment, roofing system that also can keep within reasonable moisture absorption range, is particularly favorable to the long-term use of roofing system in humid environment.

The above-mentioned embodiments are only intended to describe the preferred embodiments of the present invention, but not to limit the scope of the present invention, and those skilled in the art should be able to make various modifications and improvements to the present invention without departing from the spirit of the present invention.
