1) paying off a row plate: firstly, designing a plate arrangement according to a design drawing and by combining with the actual situation of a field; for the wall board with the width smaller than the standard, cutting and grooving are carried out; determining the quantity and the positions of the aerated concrete composite heat-insulation wallboard, and supporting and fixing pieces and pulling pieces thereof;
2) popping up a mounting control line on the main body structure according to a plate arrangement diagram of the aerated concrete composite heat-insulation batten, and mounting a supporting and fixing part (3) on an embedded part at the upper end of a frame steel beam (4); mounting a pulling part (5) on the lower end of the frame steel beam (4), and welding the pulling part (5) on a lower flange of a frame steel beam segment;
3) and (3) connecting with the main structure: hoisting one prefabricated wallboard prefabricated in the step 1) onto the supporting and fixing part (3), inserting a fixing iron part (31) of the supporting and fixing part (3) into the mounting hole (13) at the lower end of the wallboard, and welding and connecting the extending part of the supporting and fixing part (3) to an embedded part of a floor slab at the upper end of a frame steel beam (4); an L-shaped pulling piece (5) is fixed at the upper end part of the other prefabricated wallboard through an FRP connecting bolt (6) and is fixedly connected with the lower end of the frame steel beam (4);
4) and (3) plugging a PE rod: when the upper prefabricated wallboard and the lower prefabricated wallboard are spliced, the PE rod is plugged in, and the diameter of the PE rod is larger than that of the C-shaped groove
5) Adjusting the axial position and the seam width of the aerated concrete composite heat-insulating batten
Adjusting the gap between the mounting hole (13) and the supporting and fixing piece (3) and adjusting the position of the L-shaped pulling piece (5) to adjust the axial position and the seam width of the prefabricated wallboard and control the mounting precision of the wallboard;
6) plate seam processing
After the position of the prefabricated wallboard is adjusted, injecting polymer mortar or special joint grouting mortar into the slab joint; filling the joint of the upper prefabricated wallboard and the lower prefabricated wallboard by using structural adhesive;
7) mounting hole grouting
Grouting the bonding mortar into the mounting hole (13) through the grouting hole (14) by using a squeezing device;
8) wall leveling and facing construction
Scraping and smearing a heat-insulating slurry leveling layer on one side of the base plate (1) far away from the frame steel beam (4), wherein the thickness of the heat-insulating slurry is 10-25 mm, and leveling the wall surface;
after the heat-preservation slurry leveling layer is dried, uniformly wiping polymer cement mortar with the thickness of 3-5 mm and pressing alkali-resistant glass fiber mesh cloth to form an anti-cracking layer;
and after the anti-cracking layer is dried, coating flexible waterproof putty and elastic paint to form a finishing layer.
