Finished metal drip line in building construction

Abstract

The invention provides a finished product metal water drip in building operations. An inner frame of the water drip is fixedly arranged on a mounting face of a finished product in the building operations through an expansion tube screw, and rubber waterproof strips are compressed by fastening the expansion tube screw. Bayonets with corresponding positions are formed in the outer side of a flange plate of the inner frame of the water drip and the inner side of a flange plate of an outer frame of the water drip, the outer frame of the water drip is clamped on the outer side of the inner frame of the water drip, the rubber waterproof strips are compressed by the flange plate of the outer frame of the water drip, and water can be prevented from flowing into the outer frame of the water drip. A water dripping groove is formed in the center of the outer frame of the water drip, the width of the water dripping groove is about 1 cm, and the water can be effectively prevented from flowing into a building. The finished product metal water drip has the advantages that the finished product metal water drip can be fast mounted and is short in work period; the operation process is simple and convenient; the finished product after mounting is high in quality, low in cost and capable of being maintained or replaced later, finished product precision is high, and mounting straightness accuracy can reach the error of + / -1 mm per meter, and is greatly improved compared with the straightness accuracy with the error of + / -3 mm per meter of a manual plastering water drip.

Description

technical field [0001] The invention relates to the waist line of finished products such as eaves, window lintels, balconies, canopies, and protruding outer walls in building construction, and the drip line at the bottom edge of stair slabs, in particular to a metal drip line for finished products in building construction. Background technique [0002] In general building construction, drip lines need to be set on eaves, window lintels, balconies, canopies, waistlines protruding from exterior walls, and bottom edges of stair slabs. The drip line is a groove about 1cm wide, which is a measure to prevent rainwater from entering the balcony or onto the glass when it flows down the wall. The construction of the drip line is generally to inlay the drip line (groove) into the plaster layer during plastering. Manual operation requires high technical requirements, consumes a lot of man-hours, and it is difficult to control the straightness and flatness of the drip line (groove). Of...

Problems solved by technology

Manual operation requires high technical requirements, consumes a lot of man-hours, and it is difficult to control the straightness and flatness of the drip line (groove), often the finished product is not good, and the plastered surface layer is easy to crack
