Background

When an autoclaved aerated concrete slab is installed at present, an electric pipe laid in the concrete slab needs to be subjected to back grooving and slotting after a wallboard is installed, then an electric piping is laid, plugging and plastering are carried out after the electric piping is installed, and a series of anti-cracking measures are taken by adding glass fiber gridding cloth along the slotting position of the electric piping, so that cracks are prevented from being generated at the later stage of the electric pipe laying part of the back grooving. The main technical difficulties are as follows:

(1) the wall board at the joint cutting position of the laid electric pipe is seriously damaged and difficult to repair;

(2) the joint cutting position of the laid electric pipe needs to be repaired, so that time and labor are wasted, and the cost is increased;

Examples

Taking an autoclaved aerated concrete slab with the thickness of 200mm and the width of 600mm as an example; and the pre-buried distribution pipe is connected with the reserved electric distribution pipe in the floor slab to form a reserved butt joint hole. The pipe is correspondingly assembled when the concrete template is formed through the pushing device; the method avoids grooving due to laying of electrical piping after the autoclaved aerated concrete slab is installed, reduces interpenetration construction operation of various kinds of work, saves construction time and construction cost. The damage of the autoclaved aerated concrete slab is reduced, and the repair workload is reduced. The use amount of raw materials such as anti-crack glass fiber mesh cloth, pipes, plastering engineering amount and the like is reduced, and the cost is saved. The risk that cracks appear on the wall surface of the autoclaved aerated concrete slab due to the fact that grooving of a cutting seam for laying an electrical piping is increased is avoided. The position and the height of the electric box are effectively controlled.
