In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.
[0042] The following is a detailed description of the specific implementation and preferred scheme of the high-low span exterior wall termination structure proposed in this utility model.
[0043] At the junction of the roof and gable wall, a high-low span structure is formed. The junction of the exterior wall panel and the roof insulation board is typically constructed using an integrated sealing method. A high-low span flashing 3 is installed between the exterior gable wall insulation board 1 and the roof insulation board 2 to seal the junction. The high-low span flashing 3 is an integrated structure. Figure 1 , 2As shown. Although this method of directly setting up flashing at the high and low span locations is simple to construct, the exterior wall panels and roof insulation panels are integrated. If leakage occurs, the bottom of the exterior wall panels and the roof insulation panels will become damp and damaged, affecting the insulation effect.
[0044] Therefore, this utility model disassembles the overall sealing method to form a combination of bottom edge sealing and flashing.
[0045] like Figure 3 , 4 As shown, a high-low span exterior wall finishing structure mainly involves the finishing of the bottom edge of the high-low span slab and the flashing at the staggered location of the roof and gable. The gable and the roof form a high-low span structure. The high-low span exterior wall finishing structure is set at the junction of the gable and the roof, and mainly includes: gable exterior insulation board 1, roof insulation board 2, high-low span flashing 3, and bottom edge 4. The high-low span flashing 3 and the bottom edge 4 are separate structures, which can respectively ensure the quality of the bottom of the exterior wall panel and the top of the roof insulation, while improving the moisture resistance of the insulation material.
[0046] Specifically, the external insulation board 1 of the gable wall is installed and fixed on the exterior of the gable wall, and the roof insulation board 2 is installed and fixed on the roof. Since the gable wall and the roof form a high-low span structure, the roof insulation board 2 and the external insulation board 1 of the gable wall intersect. The finishing construction at the intersection is the key point of treatment, which directly affects the waterproof and moisture-proof effect of the gable wall and the roof.
[0047] The present invention firstly sets up a bottom edge trim 4, which is installed and fixed to the bottom of the external insulation board 1 of the gable wall, and forms an edge trim on the bottom of the external insulation board 1 of the gable wall; the so-called edge trim is a term commonly used in the field, which mainly refers to sealing the bottom of the board, with the purpose of closing the bottom boundary of the external insulation board 1 of the gable wall.
[0048] In conjunction with the bottom edge trim 4, this utility model also features a high-low span flashing 3. The high-low span flashing 3 is installed and fixed at the junction of the gable wall external insulation board 1 and the roof insulation board 2. One end (the lower end) of the high-low span flashing 3 is connected and fixed to the roof insulation board 2, and the other end (the upper end) is connected and fixed to the gable wall external insulation board 1. Simultaneously, the high-low span flashing 3 and the bottom edge trim 4 work together to form a finishing structure at the junction. It is easy to understand that the terms "one end" and "the other end" here do not necessarily refer to the end point; they could also refer to one side and the other side, or one side and the other side, depending on the actual structure of the high-low span flashing 3.
[0049] In some preferred embodiments, the external wall insulation board 1 is a rock wool sandwich insulation board, which is fixed to the external facade of the gable wall by bolts; the roof insulation board 2 is a rock wool sandwich insulation board, which is fixed to the roof by bolts.
[0050] More specifically, the rock wool sandwich insulation board is 150mm thick.
[0051] In some preferred embodiments, the plate bottom closing edge 4 is an aluminum plate; the high-low span flashing 3 is an aluminum plate; preferably, an aluminum veneer is used, for example, with a thickness of 0.6 mm, thus forming a high-low span outer wall closing aluminum veneer structure. The use of aluminum plates is compatible with metal roof panels, has good aesthetics, and has stronger corrosion resistance and plasticity.
[0052] In some preferred embodiments, referring to Figure 4 , the plate bottom closing edge 4 is an L-shaped structure, for example, an L-shaped aluminum veneer, one end of which is fixed to the gable outer insulation board 1 by screws, and the other end of which extends into the plate bottom of the gable outer insulation board 1.
[0053] More specifically, an angle steel can be installed at the bottom of the gable outer insulation board 1 by screws, one side of which is fixed to the gable outer insulation board 1 and the other side of which extends outward and is fixed to one end of the L-shaped aluminum veneer.
[0054] It should be noted that the other end of the L-shaped aluminum veneer extends inward into the plate bottom of the gable outer insulation board 1, and the length of the extension can be flexibly set, which can be completely extended or only extended to a portion of the thickness of the gable outer insulation board 1, such as Figure 4 approximately one-third of the thickness of the gable outer insulation board 1, which meets the sealing and waterproofing requirements.
[0055] In some preferred embodiments, continuing to refer to Figure 4 , the utility model provides a preferred high-low span flashing structure, the high-low span flashing 3 is a folded aluminum veneer, or an S-shaped aluminum veneer, one end (lower end) of which is fixed to the roof insulation board 2 by screws, the middle part of which passes through the plate bottom of the gable outer insulation board 1, and the other end (upper end) of which is fixed to the back of the gable outer insulation board 1 by screws, and the middle part of the folded aluminum veneer is bonded and sealed with the other end (extension part) of the L-shaped aluminum veneer. Through such a structure, the high-low span flashing 3 and the plate bottom closing edge 4 are completely independent, and the high-low span flashing 3 completely passes through the plate bottom of the gable outer insulation board 1, forming an effective edge sealing structure at the high-low span joint, ensuring the waterproof and moisture-proof effect of the bottom of the gable outer insulation board 1 and the roof insulation board 2.
[0056] More specifically, the middle part of the folded aluminum veneer is bonded and sealed with the other end (extension part) of the L-shaped aluminum veneer by one or more sealing glue, and the two do not need to be connected by screws, which is convenient for construction.
[0057] More specifically, as shown in Figure 5 , the folded aluminum veneer used in the high-low span flashing 3 includes a first horizontal edge 31, a first vertical edge 32, a second horizontal edge 33, and a second vertical edge 34, wherein:
[0058] The first transverse edge 31 extends obliquely downward, consistent with the slope of the roof insulation board 2, and is fixed to the roof insulation board 2 by screws; and the end (edge) of the first transverse edge 31 can form a concave edge closing structure to ensure waterproof effect;
[0059] The first vertical edge 32 extends vertically upward from the first transverse edge 31; the height of the extension matches the height of the gable outer insulation board 1 and the roof insulation board 2;
[0060] The second transverse edge 33 extends transversely inward from the first vertical edge 32 through the bottom of the gable outer insulation board 1; more specifically, it extends through the bottom from the other end (protruding part) of the L-shaped aluminum veneer;
[0061] The second vertical edge 34 extends vertically upward from the second transverse edge 33, and should extend at least to a certain height above the bottom of the gable outer insulation board 1, and then is fixed to the back of the gable outer insulation board 1 by screws.
[0062] For such a folded aluminum veneer structure, the second transverse edge 33 and the other end (protruding part) of the L-shaped aluminum veneer are sealed by one or more sealant adhesions. The other end (protruding part) of the L-shaped aluminum veneer is also a transverse edge, which can be fully adhesively sealed with the second transverse edge 33.
[0063] As is apparent from the above description, the high-low span outer wall closing structure designed by the present application adopts the form of separately setting the plate bottom edge closing and the flashing, which respectively ensures the quality of the outer wall bottom and the roof insulation board top, and improves the moisture resistance of the insulation material.
[0064] Although the above discussion includes several specific implementation details, these should not be interpreted as limiting the scope of the present application. Some features described in the context of separate embodiments can also be implemented in combination in a single implementation. Conversely, various features described in the context of a single implementation can also be implemented separately or in any suitable sub-combination in multiple implementations.
