Installation technology of aerated concrete panels

Aerated concrete panels installed

1 scope

This technology is applicable to general industry and civil architecture wall, partition wall with aerated concrete panels installed.

2 construction preparation

2.1 materials and equipment:

2.1.1 aerated concrete panel size: length 2.7m,3.0M,3.3M, width 0.6m, 10cm, 15cm. Product performance meets the design requirements.

2.1.2 cement No. 325 and more send ordinary Portland cement or slag silicate cement.

2.1.3 stones: 0.5~1.2cm fine stone.

2.1.4 coarse sand: average particle size not less than 0.5mm.

2.1.5 sand: sieve before use, average particle size 0.25mm, sediment is not 33%.

2.1.6 107 adhesive, emulsion.

2.1.7 main equipment: mixer, wheel saws, with gray iron, trolleys, drays, spade, size of the transported gas block buckets, hose, brooms, brushes, pink bag, iron trowel, hammer, holding Board, drills, wood wedges.

2.2 operating conditions:

2.2.1 according to the stud, depth size, aerated concrete panels with abrasive cutoff saw cutting. Floor dimensions minus the height of at 150mm.

2.2.2 short cord out of a corner of the plate to fix it, wash the dust of the tear, then 207 glue (water: rubber =4:1), and 1:1:3 (cement plaster: aerated concrete powder) with a good proportion, then add the above 107 glue mixing, membrane.

3 operational processes

3.1 process:

Elastic line → addressing Strip length and width dimensions → clean installation location upper end → concrete →

Spring mounting block → plate install plate

3.2 shell line: according to the design requirements of the drawing size, wall or exterior wall line of position play.

3.3 addressing Strip length and width dimensions: according to the requirements of the design drawings, annual and width of the handle, wall Board to adopt mosaic method of external wall clearance dimensions (width and height) to splice or cut. Splicing steel mosaic on the rack. First stitching to clean up, removing dust, sweep with wool dipped in water with a little moist. Operated on external coated in an adhesive strip on the mosaic surface, thickness of 2~3mm, forced to squeeze by two splice plates, seam-sealed. Mosaic extrusion adhesive scraping with a knife outside the net and on foot to check straight and square. Installed height should be higher than the net high 3cm, easy to install using the wedge will be fixed at the lower end tight.

3.4 clean installation position the upper and lower ends: clean the upper and lower ends of the strips will be installed, short of cord angle fixed firmly. Then install location top bottom clean on the concrete, bottom of the concrete damp with water.

3.5 concrete: according to the design drawings shown concrete partition Board location. High 12cm, inner casement PU 2 φ 6 bar by C15 concrete, it tastes good and smooth, as concrete has a certain value, then install the wall plate.

3.6 play Board mounting block line: in the installation location on the block line: doors and Windows line of position play.

3.7 installation plate:

3.7.1 prepared adhesive weight ratio of cement: sand: 107 gum: water =1:1:0.2:0.3. Preparation is to cement and sand dry mix, then add water laced with 107 glue mix. Adhesive should be used with mix, parking time does not exceed the 1h, tool should be promptly cleaned after use.

3.7.2 installation Shi first in article Board of top and the a side, cleaning clean, Yin water, with surgery coated scraping adhesive, will article Board erected erect, end with crowbar pad up, helped stability, makes Board bottom and the side had alignment wall sideline, again with supporting Board find are find straight, adjustment Hou forced to side extrusion, makes article Board contact surface of adhesive uniform consistent, last with crowbar from bottom pry tight, makes article Board top and floor bottom advance scraping of adhesive parts coincide, and stick tight, lower timely with wood wedge wedge tight, C15 concrete wedge stiff bean twist plug the gap between tight, conservation of 3D will wedge down, and twist bean stone concrete.

3.7.3 installation plate the contact surfaces should be brushing adhesive to facilitate bonding.

3.7.4 of the connector is installed when two adjacent strip joints should be staggered up and down position.

3.7.5 plug door holes, reserved 2cm allowance width to each side of the doorway.

3.7.6 the door frame before installation, on the installation location should be aerated concrete wall drill a deep 100mm, 30mm diameter hole, blowing dust, wet with water, again with the same diameter and long round wood stained with gum into the holes in the rubber mix for 1:2:0.5= emulsion: cement: water (by weight). Hole spacing less than 50cm, when you install a wood door frames, wood screws getting started with embedded on a log.

4 quality criteria

4.1 project:

4.1.1 use of raw materials should comply with the design requirements and the provisions of the code.

4.1.2 performance, specifications, location, methods must comply with the design requirements. Deformation and damage-free.

4.1.3 plate installed with pea stone concrete, accurate measurement of mortars and adhesives, pouring, uniform brush density. Careful conservation, strength shall meet the design requirements.

4.2 Basic projects: joint construction, component location, anchoring methods should comply with the design requirements and installation stable and secure and straight.

4.3 allowable deviation, as shown in table 4-43.

Aerated concrete panels installation tolerance table 4-43

Project tolerance (mm) method

1 3 adjacent surface flatness 2m on foot and wedged feeler Gage check

2 elevation of 5 2m supporting plate check

5 finished product protection

5.1 finished hoisting Special lifting device should be used, or use a hose hanging rope light with care.

5.2 code support to obtain a duo high and not more than 10 blocks to prevent rain, exposure, the side pieces of the mosaic, in case the force open.

5.3 transport increased protection after installation to avoid collisions.

6 quality problems to be noticed

6.1 construction of aerated concrete wall of reinforced concrete with time, location of the roof should be napping, compacting concrete has been poured, and strengthen conservation.

6.2 installation uniform coat of adhesive to the walls, the bottom wedge rolling back tight, to increase the pressure.

6.3 check carefully when installing to prevent damage no patch panels on the wall.

6.4 installation to seriously look for first Board, prevent the installation joint is not normal.

6.5 seam out of excess adhesive should be blown away in time.

7 quality records

This standard shall meet the following quality records:

7.1 aerated concrete panels factory certificate.

7.2 installation quality of aerated concrete inspection and assessment records.
