Aerated concrete slab installation
1 range
This process standard applies to the general industry and the civil construction enclosing wall, the partition wall installs with the aerated concrete slat.
2 construction preparation
2.1 Materials and main equipment:
2.1.1 aerated concrete slab specifications: length 2.7m, 3.0m, 3.3m, width 0.6m, thickness 10cm, 15cm. Product performance in line with design requirements.
2.1.2 cement; 325 and above of ordinary portland cement or slag silicate cement.
2.1.3 stone: 0.5 ~ 1.2cm fine stone.
2.1.4 coarse sand: the average particle size of not less than 0.5mm.
2.1.5 Fine sand: sieve before use, the average particle size of 0.25mm, mud content of 33%.
Rubber, emulsion.
2.1.7 The main equipment: Mixer, wheel saw, mixed with gray iron plate, trolleys, transport air block blockboard, spade, the size of buckets, rubber tube, broom, wire brush, powder package, iron trowel, Traction board, drill, wood wedges and so on.
2.2 Operating conditions:
2.2.1 According to the height of the room and the depth of the room, the aerated concrete slab is cut with a wheel saw. In the height direction by floor structure size minus 150mm.
2.2.2 will be missing flashed off the angle of the plate repair, first clean the damaged dust, and then make 207 glue (water: glue = 4: 1) together, and then 1: 1: 3 (cement: gypsum: aerated concrete Powder) with a good proportion, then add the 107 glue mixing, repair.
3 operating process
3.1 Process flow:
The position of the wire rod → the length and width of the slat plate → the upper and lower end of the installation position → pouring the concrete belt →
Install the sub-line of the slat plate → install the strip
3.2 bomb position line: According to the requirements of the design drawings, the partition board or wallboard wall position good.
3.3 Length and width of the strip: According to the requirements of the design drawings, the annual and width of the slabs are processed. The external slabs are spliced and cut according to the clearance dimensions (width and height) . Splicing in the steel staging rack on. First splicing to clean up, remove the dust, with a little sweeping dipped in water moist. With a knife outside the knife will be applied to scratch the surface of the board splicing, the thickness of 2 ~ 3mm, forced the two splicing strip extrusion, the joints tight. After splicing, use the outer knife to squeeze out the adhesive, and check the straight and Founder. The height of the strip should be higher than the installation of a net height of 3cm, easy to use when the wedge to the bottom of the fixed tight.
3.4 clean up the installation location on the bottom: the installation of the upper and lower sides of the board clean, missing corrugated angle has been patched firmly. And then install the location of the top and bottom of the concrete belt clean, the bottom of the concrete with water wet.
3.5 pouring concrete belt: according to the design drawings shown in the placement of concrete partition wall. With a high 12cm, the tiled 2φ6 steel, with C15 concrete, smooth mouth, when the concrete belt has a certain strength, and then install the partition board above.
3.6 Bundle installation block line: in the installation position will strip the line: the door and window position line bombs.
3.7 Mounting strip:
3.7.1 Preparation of adhesive, the weight ratio of cement: fine sand: 107 glue: water = 1: 1: 0.2: 0.3. Preparation method is the first dry cement and fine sand mixed, then add 107 plastic mixed with water and mix well. Adhesive should be used with the mix, the stop time can not exceed 1h, tools should be promptly cleaned with Bi.
3.7.2 installation at the top of the first and a side of the slat, clean, water, with a knife scrape the adhesive, the strip erected, the end with a crowbar mat, stabilize, so that the bottom and side of the board Aligning the wall line, and then straighten the alignment board to find straight, adjust the force to the side of the extrusion, so that the contact surface of the sticky adhesive uniform, and finally with a crowbar from the bottom pry tight, so that the top of the slab and the bottom of the floor in advance Scrape the adhesive part of the coincidence, adhesion, the lower part of the wedge wedge tightly with wood, with C15 semi-dry hard beanstone concrete wedge between the gap Niansan tight, conservation 3d, the wedge removed, fill the twist of bean curd concrete.
3.7.3 installation of the contact surface of the board should be painted adhesive, in order to facilitate bonding.
3.7.4 When the splice is installed, the joint position of two adjacent slats should be staggered up and down.
3.7.5 After the entrance of the door frame, the width of the reserved openings should be 2cm on each side.
3.7.6 Before installing the door frame, drill a hole with a depth of 100mm and a diameter of 30mm in the installation position of the aerated concrete wall to blow the dust and moisten it with water. Then, with the same diameter and length of the log, , The mixing ratio of the glue is 1: 2: 0.5 = emulsion: cement: water (weight ratio). Hole spacing of not more than 50cm, the installation of wooden frame, with wooden screws screwed into the doors of the embedded logs.
4 quality standards
