Roofing parapet wall coping weather bar and construction method thereof

Abstract

The invention provides a roofing parapet wall coping weather bar which comprises a weather bar body. A hollow cavity is formed in the middle portion of the weather bar body. An upper opening is formed in the side face of the weather bar body, and a lower opening is formed in the bottom of the weather bar body. The upper opening of the weather bar body is pressed on a parapet wall coping. The lower opening is embedded into an outer wall decoration face. A gap between the upper opening and the parapet wall coping is filled with excessive cement gum and a foaming agent. The closing-in portion of the upper opening and the parapet wall coping is sealed through a weather proofing silicone sealant. The outer edge of the lower opening is flush with the outer wall decoration face layer. Corners at the two ends of the weather bar body are oblique faces. According to the roofing parapet wall coping weather bar, time and labor are saved, the weather bar is straight and attractive, connection is firm, and the effects of the weather bar are guaranteed.

Description

technical field [0001] The invention relates to the technical field of building construction, in particular to a roof parapet pressure water retaining strip and a construction method thereof. Background technique [0002] At present, the exterior walls of high-rise buildings generally use paint finishes or spray real stone paint. In order to prevent rainwater from polluting the exterior walls, water-retaining lines are generally set on the top of the parapet wall. In addition to meeting the functional requirements, the water-retaining lines should also meet the functional requirements Straight and beautiful. The traditional practice of topping and retaining water for parapet walls: 1. Paint the cement mortar water retaining line ( figure 1 ), figure 1 Middle: Cement mortar water retaining line 1', exterior wall finish 2', parapet topping 3', parapet wall 4'; this method requires plasterers to paint on site, the finished product has poor consistency, and the appearance depe...

Problems solved by technology

The traditional practice of topping and retaining water for parapet walls: 1. Paint the cement mortar water retaining line ( figure 1 ), figure 1 Middle: Cement mortar water retaining line 1', exterior wall finish 2', parapet topping 3', parapet wall 4'; this method requires plasterers to paint on site, the finished product has poor consistency, and the appearance depends on the technical level of the operator. Moreover, the finished product is not easy to protect, and the cement mortar water retaining line is easy to be damaged; 2. The common practice is to lay stone water retaining strips ( figure 2 ), figure 2 Middle: Stone water retaining strip 5', stone glue 6', silicone weather-resistant glue 7', exterior wall finish 8', parapet topping 9', parapet 10'; this method needs to be cut into narrow strips of stone on site, The material is easy to waste, and the use of stone glue to paste the stone and the top is often not full, the flatness is not easy to control, the durability is relatively poor, and the water retaining line falls off after the cementing material ages, etc.

[0003] Although the method of painting the cement mortar water retaining line for the top of the parapet wall does not waste materials, it is time-consuming and labor-intensive. The appearance quality of the painted lines cannot be guaranteed, and the finished product is easily damaged; The method of water strips can save time and labor, but it is easy to waste the stone material if it is cut into narrow strips on site, and the stone material is pasted to the top with stone glue. Difficult to control, affecting the overall perception
