3.2 cleaning clapboard and the integration of a top surface, ground, metope, all out of metope mortar, concrete block and so on must remove and sweep, try our best to make level units.
3.3 the feeding, step; On the ground, metope and end face according to the designed position, play good partition door humanly scaled the line edges, and press plate fixed step.
3.4 with plate, repair: plate length should be according to the size of junction structure layer clear height of minus 20 ~ 30 mm. Calculate and measure the upper Windows and doors hole and a baffle plate at the bottom of the window size, and according to the size of the plate. When the plate width and the length of the partition does not adapt, should be part of the partition board splicing widened sawing (or narrow) in advance into the appropriate width, and placed in the shade. The defective board should be repaired.
3.5 the seismic requirements, should according to the design requirements with u-shaped plate fixed bar at the top of the card. At the top of the two pieces of bar flat-fell seam between the u-shaped steel card with nail fixed on the beam or plate, with Ann plate with fixed u-shaped steel plate.
3.6 dispensing adhesive: SG791 glue mixture cement and building gypsum powder, gypsum powder: SG791 = 1:0.6 ~ 0.7 (weight ratio). The preparation of the adhesive amount to a less than 20 min it is advisable to use time. Preparation of adhesive for more than 30 min solidification, shall not be used to add water to add glue to modulation, to avoid the plate seam cracks due to glue rickety.
3.7 installation partition wall board, partition panel installation order should be started, and the junction of the wall or door edge in order to install. Board side flush float ash, in metope, end face, the top surface of plate and the side split surface (phase) brush SG791 first adhesive solution, to full blown SG791 cement, according to the elastic line position in place, at the bottom of the plate with a wooden wedge, reoccupy hand horizontal pushing plate, the plate seam risked pulp, a person with special pry up the bottom of the plate, the other people dozen chock, make the partition board clamping should be solid, and then use adhesive (putty knife) will squeeze operation leveling. According to the above operation way to install the partition board in turn.
When installing a partition wall board, it is important to note that the plate alignment play good positioning line on the roof and floor in advance, and during the installation process at any time with 2 m by feet and feeler flatness of metope, in 2 m line plate inspection of verticality.
Binding end wall, should be within 24 h after using C20 harsh will be under the plate mouth of fine stone concrete wall, when the strength of concrete reaches more than 10 mpa, removed plate under chock, with the same intensity of harsh mortar pouring.
3.8 laying wire tube, unsteady junction box: according to the electrical installation drawing for position row positioning line, pipe laying wire, junction box.
All wire and tube must be suitable gypsum board hole laid, it is forbidden to horizontal and inclined shop.
Junction box, first in the borehole reaming (prevent slam), reoccupy reaming with flat, hole size moderate, founder. Hole is clean, brush SG791 first adhesive solution, reoccupy SG791 cement stabilize junction box.
3.9 Ann plumbing, gas piping card: according to the plumbing, gas piping installation drawing for level and vertical position, draw pipe clamp positioning line, hole reaming on clapboard (stuck between ban chisel), the hole is clean, brush SG791 first adhesive solution, reoccupy SG791 cement pipe clamp.
3.10 installation hanging up:
3.10.1 cupboard, the equipment can be mounted to the partition board and decorations, each piece of board can be set up two lifting point, each hoisting trolley is not more than 80 kg.
3.10.2 first hole reaming on clapboard (prevent slam), hole should be clean, brush SG791 first adhesive solution, reoccupy SG791 cement fixed up, stay in and then hang equipments.
3.11 Ann door window frame: general use for Windows and doors hole, after the Ann method of door window frame. Steel door and window must with embedded parts of door window plate welding. Wooden door window frame with l-shaped fittings connection, with wood screw connected with wooden frame, the other end plate embedded parts in the welding and door window. Gap between door frame and door window panels should not be more than 3 mm, more than 3 mm should it gasket transition. Will crack float ash clean, first brush SG791 adhesive solution, reoccupy SG791 cement sealing. Sealing is tight, in order to prevent collisions doors when they switch cracks.
3.12 plate joint processing: 10 d after installed clapboard, check whether all gap binder is good, the presence of cracks, such as cracks, should be repaired after find out the reason. Has good bonding of all joints, Yin Angle seam, to clean float ash, brush again SG791 liquid cement paste 50 mm wide glass fiber mesh belt, the Angle of partition wall in the Yang Angle paste 200 mm wide (100 mm wide on each side) a layer of glass fiber cloth. After dry scraping SG791 cement, slightly below the surface.
3.13 decorate panel:
3.13.1 general bedroom metope, with gypsum putty leveling directly, after polishing putty scraping second course (to choose different intensity of be bored with child according to request of veneer), sand again, finally do act the role of the surface.
3.13.2 partition that play a base, the general board should first brush a glue solution in the root, do concrete, terrazzo kick; Such as plastic, wood and kicking, don't brush glue solution, drill into the first chock, reoccupy nailing on the partition board.
3.13.3 metope ceramic tile should be the board face before sand, to strengthen bonding, brush SG791 glue (SG791 glue: water = 1:1) a, reoccupy SG8407 plastic adjustable cement ceramic tile adhesive (or similar) stickup ceramic tile.
3.13.4 such as local cracked panel, should first before making a spray processing, to make the next working procedure.
