Apron type spark receiving bag

Abstract

The invention provides an apron type spark receiving bag and relates to the field of welding of frameworks of building curtain walls. The apron type spark receiving bag comprises fireproof apron cloth, an apron bow, a spring steel plate bow, steel belt strings and wedge-shaped wood, wherein the upper edge of the fireproof apron cloth is bent to form the apron bow; the spring steel plate bow is fixedly wrapped in the apron bow; the steel belt strings are connected on the spring steel plate bow; a curtain wall stand column yielding area directly facing the apron bow is formed in the fireproof apron cloth; dovetail-shaped skirts are formed by fireproof apron cloth bodies on two sides of the curtain wall stand column yielding area; binding belts are arranged on edges of the skirt; the wedge-shaped wood is arranged between the apron bow and a curtain wall stand column. The spread skirt of the apron-type spark receiving bag can block a hole between the back of the stand column and a building, the position of the spark receiving bag is fixed through the internal stress between bow strings, and the curtain wall stand column is effectively protected against damage from spark.

Description

technical field [0001] The invention relates to the field of building curtain wall skeleton welding, in particular to an apron type fire bag. Background technique [0002] The connection between the skeleton of the building curtain wall and the building is inseparable from electric welding, and the operation process and technical conditions of electric welding will generate sparks and cause fires on the construction site. Over the years, there have been countless fire and safety hazards caused by on-site electric welding operations. So there are different forms of fire fights. Under normal circumstances, the fire bucket is made of galvanized steel plate to form a bucket-shaped container, such as the attached Figure 9 with 10 As shown, the fire bucket includes the fire bucket surround, the fire bucket fixed wire and the curtain wall column relief area. Connect the iron wire to the curtain wall column with the fire bucket, and make the curtain wall column relief area fit o...
