Referring to fig. 1 to 5, the present embodiment provides a cornice node waterproof structure, which is mainly used for being installed on a roof, especially an inclined roof, and for convenience of understanding, the present embodiment specifically describes one of the roofs as an example:
As shown in fig. 1 and 2, the roof includes an outer elevation 12 and an inclined roof 13, specifically, the roof includes a cross beam 10 and an inclined beam 11, and a roof panel 101 is installed on both left and lower side walls of the cross beam 10 in the viewing direction of fig. 2, wherein an outer side wall of the roof panel 101 on the left side wall of the cross beam 10 constitutes the aforementioned outer elevation 12.
The diagonal beam 11 is obliquely arranged for mounting the roof 13, and as shown in fig. 3, the roof 13 mainly comprises a directional wood shaving board layer 131, a waterproof roll layer 132 and a tile layer 133 (such as asphalt shingles) which are sequentially arranged on the diagonal beam 11 from bottom to top, so that the inclined roof 13 is formed.
The roof 13 extends outwardly relative to the facade 12 to form a cornice, which is to be understood as the part of the roof 13 extending beyond the facade 12, which cornice is referred to as part of the M in fig. 2.
In addition, the bottom of cornice is equipped with and is used for forming the strip of sealing eave 2 that supports cornice, and wherein sealing eave strip 2 can adopt the anticorrosive strip of treating as anticorrosive.
For the roof structure with cornices, one important item in the waterproof treatment is to waterproof the anti-corrosion strip so as to reduce the corrosion of the anti-corrosion strip caused by rainwater in contact with the roof structure.
Cornice node waterproof construction includes flashing board 3 and drip board 4, and wherein flashing board 3 and drip board 4 all can adopt the stereoplasm metal material. The specific structure of the flashing 3 and the drip plate 4 is shown with reference to fig. 4 and 5.
Because the cornice is part of the roof 13 and is also obliquely arranged, and the situation that one end is high and the other end is low is presented, in the embodiment, the lower end of the cornice is marked as the near-ground end; as shown in fig. 3, the flashing 3 is disposed at the near-ground end of the cornice and at least partially covers the end of the sealing eave strip 2 to form a front blocking portion 31, so that the front end of the sealing eave strip 2 can be blocked by the front blocking portion 31 of the flashing 3, and the front end of the sealing eave strip 2 is reduced from being corroded by rainwater.
The drip plate 4 is at least partially attached to the facade 12 to form a base plate part 41, whereby the attack of the facade 12 by rain water can be reduced under the barrier of the base plate part 41.
The upper end of the base plate 41 is bent toward the side away from the outer vertical surface 12 to form an upper blocking portion 42 for blocking the bottom surface of the sealing edge strip 2, and in this embodiment, the upper blocking portion 42 is preferably substantially parallel to the bottom surface of the sealing edge strip 2.
The upper blocking part 42 of the drip plate 4 can form a shielding at the lower part of the sealing eave strip 2, so that the exposed part of the bottom surface of the sealing eave strip 2 is reduced from being corroded by rainwater.
In addition, in order to receive the rainwater dropped by the draining roof 13, the embodiment further comprises a gutter 5 with an opening at the top, wherein the gutter 5 is arranged on the outer vertical surface 12 and is positioned below the cornice; the water dripping side of the flashing 3 is positioned at the upper part of the gutter 5. The gutter 5 extends substantially in the width direction of the cornice. The rainwater dropped by the cornice can fall into the gutter 5, and is collected and discharged by the gutter 5.
Wherein the base plate 41 is sandwiched between the outer vertical surface 12 and the right side wall of the gutter 5, and the gutter 5 is fixed on the outer vertical surface.
In order to enhance the strength of the gutter 5, in this embodiment, at least one rib 51 is disposed between two opposite side walls of the gutter 5, and two ends of the rib are respectively fixed, such as welded or bolted, to two opposite side walls of the gutter 5.
In order to better drain the rainwater falling from the cornice to the gutter 5 in order, in this embodiment, as shown in fig. 3, the lower end of the front baffle portion 31 of the flashing board 3 is bent and inclined downward to form a drainage portion 32 on a side far away from the outer vertical surface 12.
In addition, an end of the drainage portion 32 away from the front blocking portion 31 (in the viewing direction of fig. 2, also may be understood as a left end of the drainage portion 32) is bent downward to form a bent portion 33, and as shown in fig. 3, an extension line of the upper blocking portion 42 intersects with the bent portion 33. The bent portion 33 can form a certain degree of blocking on the left end of the upper blocking portion 42, so as to reduce rainwater from being driven between the upper blocking portion 42 and the eave strip 2.
As shown in fig. 3 and fig. 4, the upper end of the front blocking portion 31 is bent towards the side close to the outer vertical surface 12 to form an extension portion 34, the extension portion 34 is clamped between the roof 13 and the sealing eave strip 2 at the cornice position, specifically, the extension portion 34 is basically parallel to the roof 13, the extension portion 34 is fixedly clamped between the bottom wall of the waterproof coiled material layer 132 and the top wall of the sealing eave strip 2, and the design of the extension portion 34 has the meaning that the sealing eave strip 2 is matched to reduce the upward backflow of rainwater along the back surface of the tile of the roof 13, and leakage enters the cornice of the roof 13.
In order to drain down the rainwater on the base plate 41, in this embodiment, the lower end of the base plate 41 extends at least out of the bottom of the facade 12. Specifically, the lower end of the base plate 41 extends out of the bottom of the facade 12 and is bent towards the back side of the facade 12 to form a U-shaped bending part 43. At this time, the lower end of the base plate 41 acts as a drip line for dripping rainwater therefrom.
In addition, the bottom of the U-shaped bending part 43 is a sloping plate 431, and the sloping direction of the sloping plate 431 is gradually inclined from bottom to top. Such a design makes it possible to drop at a position where rainwater is mainly concentrated at the left end shoulder of the sloping plate 431.
It will be evident to those skilled in the art that the utility model is not limited to the details of the foregoing illustrative embodiments, and that the present utility model may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. The present embodiments are, therefore, to be considered in all respects as illustrative and not restrictive, the scope of the utility model being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
