[0007] A rain and snowproof connection structure for a rock wool sandwich panel wall window opening includes a steel column, wall purlins, rock wool sandwich panels, a wall window, and color-coated steel sheet folding fittings. The wall window is installed at the window opening and is fixed to the wall purlins with flat-head self-tapping screws. The wall purlins are fixed to the steel column with self-tapping screws, and the color-coated steel sheet folding fittings are fixed to the rock wool sandwich panel with rivets. It also includes color-coated steel sheet folding fittings I, II, and III, which are fixed to the wall purlins with flat-head self-tapping screws at the bottom, top, and sides of the window opening, respectively.
[0008] The color plate folding parts I and III are folded upwards at a 90° angle for 5mm on the side that contacts the wall window, pressed against the inside of the wall window, and fixed with flat-head self-tapping screws. The plane is folded downwards at a 1° angle, and the other side is folded vertically downwards, horizontally inwards, and vertically upwards in sequence. Finally, the end is connected to the color plate folding accessory.
[0009] The side of the color-coated steel sheet folding component II that contacts the wall window is horizontal and is inserted between the wall window and the wall purlin, and is fixed by flat-head self-tapping screws; the middle part is folded down 20mm into a beak shape.
[0010] Polyurethane foam is applied between the wall window and the color plate folded parts I, II, and III.
[0011] Sealant is applied to the inner and outer corners of the junctions between the wall window and the color plate folded parts I, II, and III.
[0012] Sealant is applied to the inside corner where the color-coated steel sheet folded parts I and II meet the rock wool sandwich panel on the wall.
[0013] The outer side of the wall purlin is covered with EVA thermal insulation strips.
[0014] The EVA thermal insulation strip has a specification of 5mm*40mm.
[0015] The rock wool sandwich panel adopts a tongue and groove joint on both sides, and the top and bottom edges are sealed with polyurethane.
[0016] Compared with the prior art, the present invention has the following beneficial technical effects:
[0017] This utility model relates to a wall panel with rock wool sandwich panels, where EVA insulation strips are bonded between the panels and wall purlins. This provides thermal insulation, effectively preventing heat loss and enhancing the structure's insulation performance. The lower side of the wall window features a folded-down section (I) with a 1° downward slope, while the lower and side sections are folded upwards at a 90° angle (5mm), facilitating drainage and preventing backflow of water after rain or snowmelt, thus improving the building's rain and snow protection. The upper side of the wall window features a folded-down section (II) with a 20mm downward beak, effectively preventing rain and snow intrusion and further enhancing the building's rain and snow protection. The overlapping and secure fastening of the folded-down sections and accessories avoids the traditional exposed nail method, improving the building's aesthetics. Polyurethane foam is applied between the wall window and the folded-down sections, and sealant is applied at the internal corners where they meet. Sealant is applied to the inside corner where the colored steel plate folded parts meet the rock wool sandwich panel on the wall, which improves the building's rain and snow protection and thermal insulation performance.
[0018] This invention effectively improves the rain and snow protection and heat insulation performance of the connection structure between steel structure rock wool sandwich panel walls and window openings, enhances the durability and stability of building structures, and solves the problems existing in the traditional connection structure of steel structure rock wool sandwich panel walls and window openings.

[0027] The connection structure for rain and snow protection of rock wool sandwich panel wall window openings includes a steel column 1, wall purlins 2, rock wool sandwich panels 4, wall windows 11, and color-coated steel sheet folding parts 6. The wall window 11 is installed at the window opening and is fixed to the wall purlins 2 by flat-head self-tapping screws 10. The outer side of the wall purlins 2 is covered with a 5mm*40mm EVA thermal insulation strip 3, which can effectively prevent indoor heat energy from being transferred outwards and fill the gap between the wall purlins 2 and the rock wool sandwich panels 4, thereby stabilizing the indoor temperature and providing thermal insulation. The wall purlin 2 is fixed to the steel column 1 with self-tapping screws 5. The color plate folded component accessory 6 is fixed to the rock wool sandwich panel 4 with rivets 7. The rock wool sandwich panel 4 adopts double tongue and groove joints and polyurethane edge sealing at the top and bottom, which serves to insulate the joints and prevent rain and snow from penetrating. It also includes color plate folded components I8, II9 and III14, which are fixed to the wall purlin 2 with flat-head self-tapping screws 10 below, above and on both sides of the window opening, respectively.
[0028] The aforementioned color-coated steel sheet folding parts I8 and III14 are folded upwards at a 90° angle and 5mm on the side that contacts the wall window 11, pressing against the inside of the wall window 11 and fixed with flat-head self-tapping screws 10, serving as a water-stopping function. The flat surface is also folded downwards at a 1° angle to facilitate drainage and prevent rain and snow accumulation. The other side is folded vertically downwards, horizontally inwards, and vertically upwards in sequence, finally connecting to the color-coated steel sheet folding accessory 6 at the end.
[0029] The side of the aforementioned color-coated sheet folded part II9 that contacts the wall window 11 is horizontal and is inserted between the wall window 11 and the wall purlin 2, and is fixed by flat-head self-tapping screws 10; the middle part is folded down 20mm to prevent rain and snow from entering.
[0030] Polyurethane foam 12 is applied between the wall window 11 and the color-coated steel sheet folded parts I8, II9, and III14 to provide thermal insulation. Sealant 13 is applied at the inner and outer corners of the junctions between the wall window 11 and the color-coated steel sheet folded parts I8, II9, and III14 to provide sealing and protection against rain and snow. Sealant 13 is also applied at the inner corners of the junctions between the color-coated steel sheet folded parts II9 and III14 and the wall rock wool sandwich panel 4.
[0031] During installation, first install wall purlin 2. Then, attach a 5mm*40mm EVA thermal insulation strip along the entire outer side of wall purlin 2 to provide thermal insulation and prevent heat loss from the room. Fix the rock wool sandwich panel to the wall purlin using self-tapping screws. Secure the window opening color-coated steel sheet fittings to the rock wool sandwich panel using rivets. Insert one end of the window opening color-coated steel sheet fitting into the gap between the fitting and the rock wool sandwich panel, and fix the other end to the wall purlin using flat-head self-tapping screws. The installation sequence for the window opening color-coated steel sheet fittings is as follows:
[0032] (1) First, install the lower color plate folding part I8. One side is fixed to the wall purlin with M5.5*25 flat head self-tapping screw 10, and the other side is inserted into the fixed color plate folding part accessory. The slope of the rear end folded up 5mm at 90° and the front end folded down 1° plays the role of blocking water and draining water outward.
[0033] (2) Then install the color plate folding parts III14 on both sides of the window opening (covering the lower color plate folding parts). One side is inserted into the color plate folding parts accessory, and the other end is fixed to the purlin with M5.5*25 flat head self-tapping screws. The color plate folding parts III14 are close to the color plate folding parts I8. The rear end is folded 90° 5mm to prevent water intrusion.
[0034] (3) Then install the color plate folding part II9 on the upper side of the window opening (covering the color plate folding parts on both sides). Insert one side into the color plate folding part accessory, and fix the other end to the purlin with M5.5*25 flat head self-tapping screw. Fold the color plate folding part 9 down 20mm beak to prevent rain and snow from entering.
[0035] Finally, sealant is applied to the joints between the colored steel sheet folded parts on the upper and side surfaces of the window opening and the rock wool sandwich panel in the wall, serving both waterproofing and insulation purposes. After the window frame is installed, sealant is also applied to the joints between the window frame and the colored steel sheet folded parts of the window opening, serving both waterproofing and insulation purposes.
