Description

Technical Field

[0001] This utility model relates to the field of steel structure installation technology, specifically to a connection structure between a rock wool sandwich panel and a sill wall. Background Technology

[0002] In the field of steel structure installation technology, the connection structure between rock wool sandwich panels and sill walls is a crucial part of the building exterior wall system. However, traditional connection structures have many shortcomings in practical applications, which seriously affect the waterproof performance and airtightness of building exterior walls.

[0003] Specifically, traditional steel structure wall sill construction joints often suffer from design or construction defects during installation, resulting in a lack of effective support structure at the bottom of the sill flashing, excessively low base edges, and inadequate sealing at the overlaps. This easily leads to water leakage at the steel structure wall sill location. Such leakage not only affects the building's functionality but may also damage the building structure and shorten its lifespan.

[0004] In addition, traditional connection structures often lack effective insulation and sealing measures, such as EVA insulation strips and vertical keel sealing accessories, between the vertical keel and the rock wool composite board. This makes the building's exterior walls prone to air leakage when the temperature changes, reducing the building's thermal insulation performance and airtightness. At the same time, the lack of effective insulation measures may also cause cold bridging, further affecting the building's thermal insulation effect and user comfort.

[0005] Therefore, in order to address the above problems, there is an urgent need for an improved connection structure between rock wool sandwich panels and sill walls to improve the waterproof performance and airtightness of building exterior walls, eliminate water leakage and cold bridging, and ensure the safety, comfort and durability of buildings.

Below the flashing edge 72, a drip edge 73 is provided, which is 30mm high, to guide rainwater to drain smoothly and avoid water accumulation.

[0036] An EVA insulation strip 10 with a thickness of 5mm and a width of 20mm is installed between the vertical keel 2 and the rock wool composite board 11 to effectively isolate heat transfer and improve thermal insulation performance. A vertical keel sealing accessory 4 is installed between the bottom of two adjacent vertical keels 2 and fixed to the wall purlin 1 to seal the gap between the vertical keels and enhance the sealing and stability of the overall structure. Example

[0037] The connection structure between rock wool sandwich panels and sill walls is an improved construction node form for steel structure wall sill wall positions. It includes vertical keel sealing accessories (0.5mm thick, trimmed on-site when encountering vertical keels) and M6.3*25 self-tapping screws II5 fixed to the wall purlins 1 at 500mm intervals; it includes a 200mm wide, 3.0mm thick backwater edge support 6 set at 1500mm intervals and a 0.6mm sill wall flashing edge support 7, a galvanized rock wool composite panel starting bracket 8, two M6.3*38 self-tapping screws III9, a 5mm thick EVA thermal insulation strip 10, and polyurethane foam 12 filling.

[0038] This construction node design, through improvements to previous sill wall nodes, effectively solves common problems such as water leakage, air leakage, and cold bridging at the sill wall location. It also improves the stability of the rock wool composite panel at the sill wall location, reduces future maintenance costs, and is suitable for widespread application in steel structure buildings.

[0039] The wall flashing edge trim 7 is installed with a 60mm high drip edge at the vertical fixing position with the Z-shaped flashing edge trim support 6.

[0042] A Z-shaped flashing support 6 is installed every 1500mm below the flashing edge piece 7, and is fixed to the bottom of the vertical keel 2 with two M6.3*38 self-tapping screws Ⅲ9.

[0043] Based on the spacing of the vertical keel 2, cut the vertical keel sealing accessory 4 on site, and fix it to the outside of the wall purlin 1 and between the vertical keels 2 with one M6.3*25 self-tapping screw II 5 every 500mm.

[0044] To improve the airtightness of the sill area, before installing the rock wool composite panels, apply 5mm thick and 20mm wide EVA thermal insulation strips to the outside of the vertical joists using double-sided tape. Based on the spacing of the vertical joists, cut the vertical joist sealing accessories on-site and fix them to the bottom of the vertical joists with M6.3*25 self-tapping screws, with a spacing of no more than 500mm. After the rock wool composite panels are installed, fill the cavity between the rock wool composite panels and the sill flashing with polyurethane foam, and then apply sealant to the angle between the sill flashing and the rock wool composite panels to improve the airtightness of the sill area and prevent cold bridging.

[0045] A 60mm high flashing edge is installed on the wall flashing component, and a Z-shaped flashing edge support is installed every 1500mm. Together with the galvanized rock wool composite board starting bracket, it is fixed to the bottom of the vertical keel with two M6.3*38 self-tapping screws I3.

[0046] The longitudinal overlap length of the flashing for the retaining wall should be no less than 150mm. Two coats of sealant should be applied within the overlap length, and the flashing should be anchored with rivets spaced less than 50mm apart. The angle between the flashing and the rock wool composite board should be fully coated with sealant. This effectively improves the waterproofing performance of the retaining wall.

[0047] After the vertical keel is installed, before installing the rock wool composite board, attach a 5mm thick and 20mm wide EVA thermal insulation strip to the outside of the vertical keel with double-sided tape. According to the spacing of the vertical keel, cut the vertical keel sealing accessories on-site and fix them to the outside of the wall purlins at the bottom of the vertical keel with M6.3*25 self-tapping screws. The spacing of the self-tapping screws should not exceed 500mm. After the rock wool composite board is installed, fill the cavity between the rock wool composite board and the flashing with polyurethane foam, and then apply sealant to the angle between the flashing and the rock wool composite board. This effectively improves the airtightness of the flashing area.
