Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, and particularly relates to a waterproof structure for the upper opening of a window on a brick wall with an externally hung sandwich panel. Background Art

[0002] Due to its excellent fire resistance, heat insulation, high strength, short installation period and other advantages, sandwich panels are increasingly used in public buildings, industrial buildings, scientific research buildings and other fields, such as sandwich panel exterior walls. At present, the upper edge of the window on the sandwich panel exterior wall is usually edged with an "L"-shaped bent steel plate. The vertical edge steel plate is directly fixed to the exterior wall sandwich panel with rivets. A through-sealant is applied between the upper end position of the vertical edge steel plate and the exterior wall sandwich panel. The horizontal edge steel plate is fixed between the sandwich panel and the window frame.

[0003] In the vertical direction, since the edge steel plate is close to the exterior wall sandwich panel, the quality of the sealant application is poor and it is easy to crack. When the sealant in the vertical direction fails due to long-term weathering or cracks, water will accumulate between the sandwich panel and the edge steel plate, and even the water will flow into the room along the edge steel plate. If the water accumulates between the sandwich panel and the edge steel plate for too long, the sandwich panel will mildew and rot, which will seriously affect the functionality of the sandwich panel. Summary of the Invention

[0004] In order to overcome the deficiencies of the prior art, the utility model provides a waterproof structure for the upper opening of a window on a brick wall with an externally hung sandwich panel, which can improve the sealing effect, solve the water accumulation problem, and is beneficial to ensuring the construction quality.

[0005] To achieve the above object, the waterproof structure for the upper opening of a window on a brick wall with an externally hung sandwich panel of the utility model includes a lintel. A window body is connected below the lintel. A vertical wall purlin is arranged on the outdoor side of the lintel. A horizontal purlin at the upper window opening is arranged at the bottom of the vertical wall purlin. An exterior wall sandwich panel is arranged on the side of the vertical wall purlin away from the lintel. A composite board bracket is arranged at the bottom of the vertical wall purlin. The bottom end of the exterior wall sandwich panel is arranged on the composite board bracket. A window upper edge closing steel plate covering the composite board bracket and the bottom of the exterior wall sandwich panel is arranged at the bottom of the horizontal purlin at the upper window opening.

[0006] Further, one end of the window upper edge closing steel plate extends between the window body and the lintel. A vertical plate perpendicular to the window upper edge closing steel plate is arranged at the end of the window upper edge closing steel plate away from the window body. The vertical plate extends downward along the vertical direction. A bottom plate is arranged at the end of the vertical plate away from the window upper edge closing steel plate. The bottom plate extends in the direction away from the window upper edge closing steel plate. A side plate covering the bottom end of the exterior wall sandwich panel is arranged at the end of the bottom plate away from the window upper edge closing steel plate. By forming a structure close to a concave shape at the lower end position of the exterior wall sandwich panel with the window upper edge closing steel plate, it can effectively prevent the situation that rainwater flows into the room along the inner side of the window upper edge closing steel plate due to the cracking or weathering failure of the sealant.

[0007] Further, the side plate extends upward in the vertical direction. The top of the side plate bends towards the exterior wall sandwich panel and contacts the exterior wall sandwich panel. An inner U-shaped lining is provided inside the top of the side plate. One side of the U-shaped lining is connected to the bent portion at the top of the side plate, and the bottom of the U-shaped lining is fixed on the composite plate bracket. By using the U-shaped lining as the adapter between the exterior wall sandwich panel and the window upper edge closing steel plate, the angle at the joint position between the window upper edge closing steel plate and the exterior wall sandwich panel is 90°, effectively improving the forming quality of the sealant application and reducing the possibility of sealant cracking.

[0008] Further, one end of the bottom plate away from the window upper cross purlin slopes downward, and a drain hole is provided at one end of the bottom plate away from the window upper cross purlin. The accumulated water drains along the slope, effectively preventing the backflow of water into the room and avoiding the influence of long-term water accumulation on the functionality of the exterior wall sandwich panel.

[0009] Further, an inner water guide plate is provided between the window upper cross purlin and the composite plate bracket. One end of the inner water guide plate extends upward in the vertical direction, and the other end of the inner water guide plate is located in the cavity formed by the window upper edge closing steel plate. If water leakage occurs at the top inner side of the exterior wall sandwich panel, the water can flow into the bottom along the inner water guide plate, preventing the water from flowing into the room along the window upper edge closing steel plate and blocking the accumulated water in the bottom groove at the same time.

[0010] Further, a first sealant strip is provided between the outer side of the top of the side plate and the outer side of the exterior wall sandwich panel, a second sealant strip is provided between the outer side of the top of the window body and the bottom side of the window upper edge closing steel plate, and a third sealant strip is provided between the inner side of the top of the window body and the bottom side of the lintel.

[0011] Further, the inclination angle of the bottom plate relative to the horizontal plane is 2°.

[0012] Further, the cross-section of the composite plate bracket is concave. The outer side edge of the bottom end of the exterior wall sandwich panel covers the outside of the composite plate bracket, and a convex portion adapted to the depression of the composite plate bracket is provided on the inner side edge of the exterior wall sandwich panel.

[0013] The waterproof structure for the upper edge of the window of the brick wall with externally hung sandwich panel of the present utility model improves the sealing effect of the exterior wall sandwich panel and can solve the problem of long-term water accumulation between the exterior wall sandwich panel and the closing steel plate, which is beneficial to improving the construction quality of the closing of the upper edge of the sandwich panel window.
