Description

Technical Field

[0001] The utility model relates to the technical field of construction, in particular to an AAC board parapet and metal roof waterproof structure. Background Art

[0002] With the continuous development of modern construction technology, steel structures have gained widespread application in high-rise buildings, industrial plants, and schools due to their advantages such as high strength, light weight, and fast construction. At the same time, AAC panels (autoclaved aerated concrete panels), as a lightweight building material with excellent sound insulation and thermal insulation properties, are also gradually being used in building exterior walls and partitions. However, when combining steel structures with AAC panels, waterproofing issues, particularly at the junction of parapets and metal roofs, have become a pressing challenge.

[0003] Traditional building parapets are typically constructed of concrete or brick, resulting in slow construction and significant environmental pollution. For buildings primarily constructed with steel, the use of steel and AAC panels to create parapets can shorten construction time, reduce pollution, and maintain consistency with the building's exterior walls. However, the traditional AAC panel parapet and metal roof waterproofing joint structure often presents challenges such as complex construction, high material costs, and unsatisfactory waterproofing. For example:

[0004] Method 1: Traditionally, concrete is poured on top of the parapet, and waterproofing membrane is applied at the base where it meets the metal roof. This method causes the concrete to age and leak over time. Rainwater seeps from the capping into the joint between the steel structure and the AAC board, and the waterproofing membrane at the base is prone to aging, deformation, or damage due to improper construction, which can lead to leakage.

[0005] Method 2: Use flashing to cover the top and base of the parapet and the junction with the metal roof to form a barrier. This approach has certain effects but has too many limitations. It requires that the height difference between the top of the parapet and the metal roof panel should not be too large, and it is not suitable for steel structure AAC board parapets. Utility Model Content

[0006] Therefore, the technical problem to be solved by the present invention is that the AAC board parapet and metal roof waterproofing node structure in the prior art often has the problems of complex construction, high material cost and unsatisfactory waterproofing effect.

[0037] Example

[0038] This embodiment provides an AAC board parapet and metal roof waterproof structure, such as Figure 1 As shown, it includes a parapet 1, a partition wall 2, a roof 5 and a flashing 6.

[0039] like Figure 1As shown, the parapet 1 includes an AAC exterior wall panel 11, a steel column 12 and an H-shaped steel beam 13. The steel column 12 and the H-shaped steel beam 13 are installed with the main steel structure and serve as components of the main steel structure. The AAC exterior wall panel 11 is connected to the H-shaped steel beam 13 and the steel column 12. The H-shaped steel beam 13 and the steel column 12 are used to hang the AAC exterior wall panel 11. When in use, the steel column 12, the H-shaped steel beam 13 and the AAC exterior wall panel 11 together constitute the parapet 1.

[0040] In this embodiment, the AAC board parapet and metal roof waterproof structure further includes a cover plate 4 , which is provided to cover the connection between the AAC exterior wall panel 11 and the H-shaped steel beam 13 .

[0041] like Figure 1 As shown, in order to prevent water seepage at the joint between the AAC exterior wall panel 11 and the H-shaped steel beam 13, a cover plate 4 is used to cover the top. The cover plate 4 is prefabricated in the factory and arranged along the length direction of the top of the parapet 1. It is fixed to the parapet 1 by self-tapping screws 3, wherein the self-tapping screws 3 are equipped with waterproof rubber pads.

[0042] In this embodiment, if Figure 1 As shown, the roof 5 includes a roof panel 53, a spacer keel 51, and a spherical lock 52. The spherical lock 52 is connected between the roof panel 53 and the spacer keel 51. The spacer keel 51 is fixed to the underside of the roof panel 53 through the spherical lock 52. The partition wall 2 includes a vertical keel 21, a color steel plate 22, and a rock wool filler 23. One end of the vertical keel 21 is fixed to the H-shaped steel beam 13, and the other end of the vertical keel 21 is fixed to the spacer keel 51. The color steel plate 22 is connected to the vertical keel 21, and the rock wool filler 23 is located inside the color steel plate 22.

[0043] like Figure 1 As shown, after the roof 5 and roof trusses are installed, a vertical partition wall 2 is installed between the parapet 1 and the roof 5. The main frame of the partition wall 2, the vertical keel 21, is fabricated on-site from square steel. The upper portion of the vertical keel 21 is welded to the H-beam 13, and the flange edges of the partition wall 2 and the H-beam 13 are aligned to ensure aesthetics and secure installation. The lower portion of the vertical keel 21 is seated on the partition keel 51 and welded to it. Color-coated steel plates 22 are fixed to the inner and outer sides with self-tapping screws 3 for external waterproofing. The interior is filled with rock wool filler 23.

[0044] In this embodiment, the flashing plate 6 is arranged at the connection between the roof 5 and the partition wall 2. The upper part of the flashing plate 6 is fixed to the vertical keel 21 and the color steel plate 22, and the lower part thereof spans the nearest spherical lock 52 and falls on the upper side of the roof panel 53.

[0045] Specific as Figure 1As shown, in order to ensure the waterproof requirements of the joint between the roof 5 and the partition wall 2, a flashing plate 6 is set above the joint after the partition wall 2 is installed. The upper part of the flashing plate 6 is fixed to the vertical keel 21 and the color steel plate 22 by self-tapping screws 3, and its lower part crosses the nearest spherical lock 52 and falls on the upper surface of the roof panel 53 to prevent rainwater from flowing into the joint.

[0046] In this embodiment, if Figure 1 As shown, the flashing plate 6 is Z-shaped, one end of the flashing plate 6 is fixed to the roof panel 53, and the other end of the flashing plate 6 is fixed to the vertical keel 21 and the color steel plate 22. The middle of the flashing plate 6 is sloped toward the roof panel 53.

[0047] By setting the flashing plate 6 into a Z shape, the two ends of the flashing plate 6 can be conveniently fixed to the roof panel 53, the vertical keel 21 and the color steel plate 22. After the flashing plate 6 is fixed, the middle of the flashing plate 6 is inclined toward the roof panel 53, so that rainwater does not stay on the flashing plate 6, but directly slides down along the inclined direction of the flashing plate 6.

[0048] The AAC board parapet and metal roof waterproof structure provided in this embodiment has excellent waterproofing effectiveness. The waterproofing measures formed by the flashing plate 6, the color-coated steel plate 22, and the cover plate 4 effectively prevent rainwater penetration and improve waterproof performance. Its construction is simple, with rational joint design and a simple construction process, which can reduce construction difficulty and cost. The optimized joint design reduces stress concentration and increases the service life of the joints. The joint design is easy to inspect and repair, facilitating subsequent maintenance.

[0049] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will readily appreciate that other variations or modifications based on the above descriptions are possible. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
