Description

TECHNICAL FIELD

[0001] The utility model relates to a roof waterproof exhaust module and roof waterproof exhaust device, specifically relates to the roof waterproof exhaust module and roof waterproof exhaust device that water vapor in roof is discharged to the side and waterproof to roof. BACKGROUND

[0002] Roof as an important part of building, it provides the function of resisting wind, frost, rain, snow, solar radiation, temperature change etc. for building. In order to further improve the various properties of roof, the field is making various researches. Among them, roof waterproof engineering as an important subproject of housing construction, its main purpose is to prevent the penetration of water and water vapor.

[0003] In order to waterproof, roof usually includes waterproof layer. Specifically, the structure of waterproof roof includes structural layer, slope layer, insulation layer, waterproof layer, isolation layer, protection layer etc. from bottom to top.

[0004] However, according to the quality of construction, the waterproof layer of roof may be damaged, and the damage point usually has great concealment, so it is difficult to find in the process of forming the waterproof layer. Even if there is no damage point in the process of forming the waterproof layer, it is also possible to damage the waterproof layer in the later construction process. When the waterproof layer is damaged, the insulation layer and slope layer etc. under the waterproof layer are easily penetrated by a large amount of water vapor. When the temperature rises, the large pressure formed by these water vapor has no place to discharge, part of which will rise up to the waterproof layer, thereby forming a larger damage or forming "water channeling", and the other part will penetrate into the indoor along the capillary crack of the roof structure, thereby causing indoor water leakage.

[0005] In engineering practice, when the existing roof leaks, the roof can be opened locally along its four sides to discharge the pressure of water vapor in the roof, thereby improving the leakage condition, and even no longer leaking. However, this is only an emergency treatment measure, and the roof after local opening cannot resist rain and snow etc., therefore, it needs to be repaired again, and when the roof leaks again, only the above-mentioned emergency treatment measure can be repeated.

[0006] In order to solve the above problems, the field usually sets up longitudinal and transverse exhaust passages in the insulation layer, and sets up exhaust pipes protruding from the roof on the exhaust passages, so as to discharge the gas in the insulation layer in time. However, the problem of this solution is that the exhaust passage structure is complex, and occupies a large space in the insulation layer, in addition, the exhaust pipe protruding from the roof is easy to be damaged, when damaged or fallen off, the rain and snow outside is easy to enter the longitudinal and transverse exhaust passage penetrating the insulation layer through the damaged pipe opening, thereby causing more serious leakage.

[0007] As another solution, the waterproof plate for the waterproof layer has been improved by those skilled in the art, that is, a through air vent is formed on the waterproof plate to discharge water vapor in the structural layer and the waterproof layer outward, and a cap is arranged on the air vent to prevent external rain and snow from entering. However, there are problems in that: first, the structure is complex, the installation is cumbersome, and the surface is uneven and easy to damage; second, when a separation layer, a protection layer and the like are further formed on the waterproof layer, the path for discharging water vapor upward may be covered or even blocked, so that the air vent is difficult or even impossible to discharge, and therefore the air exhaust effect is poor.

[0008] In summary, there is an urgent need for a waterproof and air exhaust device that not only retains the simple structure of the existing roof, but also is easy to set up and maintain, and has excellent waterproof and air exhaust effect. Content of the utility model

When the description of the known structure or feature will unnecessarily obscure the main idea of the present application, the description of these known structures or features will be omitted.

[0061] The utility model provides a kind of roofing waterproof exhaust module, it can be configured in the four around of roofing, for along lateral discharge water vapor in the roofing, and the four around of the roofing is waterproofed.

[0062] Figure 1 It is the schematic diagram of the roofing waterproof exhaust module of one embodiment of the present application combined with building.

[0063] As Figure 1 Indicated, the building 100 can include the roofing 110 of top and the parapet 120 of top four around. The structure of the roofing 110 can include structural layer 111, thermal insulation layer 112, waterproof layer 113 and protective and finishing layer 114 from bottom to top. Among them, the side surface of the thermal insulation layer 112, the waterproof layer 113 and the protective and finishing layer 114 is spaced from the side surface of the structural layer 111 to the inside, so that the four around of the upper surface of the structural layer 111 is open. The parapet 120 is configured in the four around edge of the upper surface of the structural layer 111. At this time, the roofing 110 and the parapet 120 enclose the space that the cross section is substantially U-shaped and overall surrounds the four around of the roofing 110, the roofing waterproof exhaust module 200 of the present application can be configured in the space, to discharge water vapor in the roofing 110 along lateral direction (the direction of dotted arrow in the figure) and waterproof the four around of the roofing 110. Figure 1

[0064] Figure 2 It is the perspective view of the roofing waterproof exhaust module of one embodiment of the present application.

[0065] As Figure 2 ​As shown, the roof waterproofing and exhaust module 200 can be in a strip shape as a whole, and can have a specified length (e.g., 1 m or 2 m, etc.) so that a proper number of the roof waterproofing and exhaust modules 200 can be arranged along the periphery of the roof 110 according to the circumference of the roof 110. In addition, the roof waterproofing and exhaust module 200 can be made of UPVC or the like, so that the roof waterproofing and exhaust module 200 can be cut according to the length to be laid, and light weight can be easily achieved. Although not shown, the roof waterproofing and exhaust module 200 can also be formed to be laterally bent or curved at a specified angle (e.g., 90 degrees) so as to wrap the corner of the roof 110, so as to be more fitted to the periphery profile of the roof 110.

[0066] The roof waterproofing and exhaust module 200 can further include a sealing strip 240, which can be arranged at both ends of the roof waterproofing and exhaust module 200 in the length direction thereof. In this way, not only the ends of a single roof waterproofing and exhaust module 200 can be sealed, but also the gap between two adjacent roof waterproofing and exhaust modules 200 can be sealed when the modules are arranged in sequence, so as to ensure the waterproofing effect.

[0067] Referring again to Figure 1 , the roof waterproofing and exhaust module 200 can include a main body portion 210 and an extension portion 220.

[0068] The main body portion 210 can abut against the side surface of the thermal insulation layer 112 to exhaust the water vapor in the thermal insulation layer 112 laterally, so as to avoid the water vapor exhaust path being blocked by the waterproofing layer 113, the protection and finishing layer 114, etc. on the thermal insulation layer 112. The extension portion 220 can abut against the parapet 120 to cover the open part in the upper surface of the structural layer 111, so as to prevent rain and snow from seeping into the roof 110.

[0069] At this time, the waterproof layer 113 can be arranged on the upper portion of the main body portion 210 and the thermal insulation layer 112. For example, when the waterproof layer 113 is a waterproof roll material, the waterproof roll material can be laid on the thermal insulation layer 112 after the thermal insulation layer 112 and the parapet 120 are formed on the structural layer 111 and the roof waterproof exhaust module 200 is arranged. The edge of the waterproof roll material is overlapped on the upper surface of the main body portion 210, so that the thermal insulation layer 112 is waterproofed, and the rain and snow outside is prevented from penetrating into the contact surface between the thermal insulation layer 112 and the roof waterproof exhaust module 200. The waterproof layer 113 is not limited to the waterproof roll material, and can be other waterproof materials such as waterproof paint, waterproof board and the like commonly used in the art. The roof waterproof exhaust module 200 can further include a cover plate 250 arranged above the main body portion 210 to fix the waterproof layer 113 of the roof 110 on the upper surface of the main body portion 210. The upper surface of the cover plate 250 can be formed with a certain inclination angle to facilitate the rain and snow to slide off, so that the rain and snow is prevented from being accumulated on the cover plate 250 for a long time. The lower surface of the cover plate 250 can be formed to match the shape of the upper surface of the main body portion 210 to firmly fix the waterproof layer 113.

[0070] The overall structure of the roof waterproof exhaust module 200 is described above. The details of the main body portion 210 and the extension portion 220 are described below. First, the main body portion 210 is described.

[0071] Figure 3 is a sectional view of the roof waterproof exhaust module according to an embodiment of the present application.

[0072] As shown in Figure 3 , the cross section of the main body portion 210 can be a polygon, that is, the outer shape of the main body portion 210 can be a multi-prism shape extending along the length direction thereof, for example, a four-prism, a five-prism or a six-prism, and the like, as long as the main body portion 210 can abut against the thermal insulation layer 112 to exhaust the water vapor in the thermal insulation layer 112. For example, the main body portion 210 can have a flat lower surface to be stably arranged on the upper surface of the structural layer 111. The main body portion 210 can further have a side wall (for example, the first side wall 211 described below) extending vertically upward from the lower surface to fit the side surface of the thermal insulation layer 112. The main body portion 210 can further have a flat upper surface or a prescribed protruding shape to fix the waterproof layer 113 together with the cover plate 250 (refer to Figure 1 ).

[0073] The main body 210 may have an exhaust channel 230 extending from its first sidewall 211 to its second sidewall 212 to laterally discharge moisture from the insulation layer 112 of the roof 110. The first sidewall 211 may be a sidewall that abuts against the insulation layer 112, and the second sidewall 212 may be a sidewall of the main body located opposite the first sidewall 211. In this case, moisture from the insulation layer 112 can enter the exhaust channel 230 from the first sidewall 211 side and be discharged outwards from the second sidewall 212 side.

[0074] The exhaust channel 230 may include: a first opening 231 formed on the first sidewall 211; and a second opening 232 formed on the second sidewall 212, and waterproof and breathable membranes (not shown) may be provided on the first opening 231 and the second opening 232 respectively. In this case, moisture in the insulation layer 112 can enter the exhaust channel 230 through the first opening 231 and be discharged outwards through the second opening 232. However, external rain and snow cannot enter the exhaust channel 230 through the second opening 232, nor can they enter the insulation layer 112 through the first opening 231.

[0075] The shapes of the first opening 231 and the second opening 232 can be square, circular, elliptical, or other shapes, as long as they can smoothly discharge water vapor. Furthermore, the areas of the first opening 231 and the second opening 232 can be set by those skilled in the art according to actual conditions, but they should not be too large to avoid the main body 210 having excessively large holes in one or more places, which would reduce the strength of its structure.

[0076] The interior of the main body 210 may have a hollow portion 233 extending along the length of the main body 210. The hollow portion 233 communicates with the first opening 231 and the second opening 232 and forms the exhaust channel 230. Compared with individual exhaust channels that each penetrate the main body 210, the exhaust channel 230 of this invention is easier to mass-produce and has more internal space. Therefore, it not only has excellent water vapor discharge efficiency, but also reduces the weight of the main body 210, thereby achieving lightweighting and saving manufacturing costs.

[0077] Figure 4 It is based on Figure 3 The section line AA in the figure shows the cross-sectional view.

[0078] like Figure 4As shown, as a preferred embodiment, in the hollow portion 233, reinforcing partitions 234 can be arranged at regular intervals. The reinforcing partitions 234 can extend along the width direction and the height direction of the hollow portion 233 and close the hollow portion 233 to support the main body portion 210. The interval between two adjacent reinforcing partitions 234 can be appropriately selected according to the volume, shape, cross-sectional area, material, etc. of the main body, as long as sufficient support strength can be provided to the internally hollow main body portion 210, and the utility model is not limited thereto.

[0079] On the other hand, the main body portion 210 can be formed with a plurality of first openings 231 and a plurality of second openings 232 to more efficiently discharge water vapor.

[0080] Figure 5 is a schematic view of a first side wall of a main body portion of an embodiment of the utility model.

[0081] Referring to Figure 3 and Figure 5 , as an embodiment, the first openings 231 can be formed in the first side wall 211 along the length direction of the main body portion 210. Preferably, the first openings 231 can be formed in multiple rows (for example, two rows) spaced apart along the height direction of the main body portion 210 in the first side wall 211 to increase the distribution range of the first openings 231 on the first side wall 211, so that the side surface of the heat preservation layer 112 as a whole more uniformly contacts more first openings 231, thereby further improving the water vapor discharge effect.

[0082] Figure 6 is a schematic view of a second side wall of a main body portion of an embodiment of the utility model.

[0083] Referring to Figure 3 and Figure 6 , as an embodiment, the second openings 232 can be formed in the second side wall 212 along the length direction of the main body portion 210. Preferably, the second openings 232 can be formed in the upper side of the second side wall 212 along the length direction of the main body portion 210, so that even if there is rain and snow at the second side wall 212, the second openings 232 can be ensured to be above the water surface or snow surface and not be blocked by rain and snow, thereby smoothly discharging water vapor.

[0084] The above describes the main body portion 210. The following describes the extension portion 220.

[0085] Referring again to Figure 1 and Figure 3The extension 220 can extend outward along the width direction of the main body 210 from the bottom edge of the second side wall 212 and be bent upward to abut against the parapet 120 of the roof 110. In this way, the bottom of the parapet 120 can be further covered while the part of the upper surface of the structure layer 111 is opened, so as to prevent rain and snow from leaking into the roof 110 through the bottom of the parapet 120.

[0086] As shown in Figure 1 , the width of the extension 220 extending along the width direction can be determined according to the distance between the thermal insulation layer 112 and the parapet 120, as long as the space between the thermal insulation layer 112 and the parapet 120 can be completely filled together with the main body 210. The height of the upward bending of the extension 220 can be determined according to the actual roof waterproof standard, for example, the waterproofing membrane used as the waterproof layer 113 should generally cover the bottom of the parapet 120 to a height of 250 mm, therefore, the height of the upward bending of the extension 220 can also be 250 mm to meet the specified waterproofing requirements. In addition, the parapet 120 is generally formed with a closing groove 121 (for example, a strip-shaped groove with a depth of 30 mm) at a height of 250 mm to fix the upper edge of the waterproofing membrane. Therefore, the top end of the extension 220 can be further bent away from the main body 210 to abut against the closing groove 121 of the parapet 120, so as to further improve the waterproofing effect.

[0087] In addition to the roof waterproofing and exhaust module 200, the utility model also provides a roof waterproofing and exhaust device.

[0088] Figure 7 is a schematic view of a roof waterproofing and exhaust device according to an embodiment of the utility model, which is shown in combination with a thermal insulation layer and a parapet.

[0089] As shown in Figure 7 , taking a square roof as an example, the roof waterproofing and exhaust device 300 can be arranged in a square manner between the thermal insulation layer 111 and the parapet 120 to wrap the side surface of the thermal insulation layer 111 and abut against the parapet 120, so as to perform waterproofing and exhaust.

[0090] Figure 8 is a schematic view of the B area in Figure 7 enlarged.

[0091] As shown in Figure 8As shown, the roof waterproof exhaust device 300 can be formed by sequentially splicing a plurality of the roof waterproof exhaust modules 200. Specifically, each of the roof waterproof exhaust modules 200 can be configured in a manner that the main body part 210 thereof abuts against the side surface of the thermal insulation layer 112 and the extension part 220 thereof abuts against the parapet wall 120, and spliced in a manner that the sealing strips 240 at the ends of two adjacent roof waterproof exhaust modules 200 are in close contact with each other. A plurality of the roof waterproof exhaust modules 200 extending in a straight line and four roof waterproof exhaust modules 200 bent by 90 degrees can be spliced to form the above-mentioned square shape.

[0092] The embodiments of the present application are described above, but this is only for helping to comprehensively understand the present application, the present application is not limited to this, and those skilled in the art can make various modifications and deformations from these records. Therefore, the technical idea of the present application is not limited to the above-mentioned embodiments, the appended claims and its equivalent or equivalent deformations all belong to the scope of the present application.
