Wall hole opening construction method adopting encased angle iron method
The invention discloses a wall hole opening construction method adopting an encased angle iron method. The wall hole opening construction method includes the steps of firstly, designing angle iron; secondly, determining the size and the position of a hole by flicking a chalk line on a wall where the hole is to be opened; thirdly, scraping away a mortar painting layer at the position, nearby the position of the chalk line, of the top of the hole, and selecting a mortar joint closest to the chalk line as a horizontal mortar joint embedded in the angle iron, wherein the depth of the horizontal mortar joint is 80 mm, the length of the horizontal mortar joint is equal to the width of the hole after the hole extends leftwards by 500 mm and extends rightwards by 500 mm, the hole extends leftwards by 500 mm and extends rightwards by 500 mm to serve as supporting points of the angle iron, and a 160 mm mortar joint is formed in the other side of the wall if the wall thickness is 240 mm; fourthly, after the mortar joins are cleaned, structural cement gum is smeared into the mortar joints, horizontal limbs of the angle iron are inserted into the horizontal mortar joint to enter the wall till perpendicular limbs of the angle iron are flush with the wall; fifthly, filling supporting positions of the angle iron through a thin steel plate; sixthly, conducting construction in the same way on the other side of the wall according to the first step to the fifth step; seventhly, scraping away mortar face layers on the two sides of the portion, inside the chalk line, of the inner wall face, detaching bricks to open the hole from top to bottom till reaching a floor; eighthly, adding batten plates or lacing and batten elements to the manufacture angle iron.
