How to install in the construction of external wall insulation XPS Plastic extruded board? At present, the extruded board for thermal insulation is a new type of thermal insulation building material that is widely used. The extruded board is recycled from waste plastics and then processed for use. It has a certain environmental protection. In addition, its thermal insulation, waterproof and moisture-proof properties can save energy, heating supply in winter and air-conditioning electricity in summer. XPS Extruded board is widely used in building exterior wall and floor. How about the construction process of exterior wall extruded board insulation board? How to install extruded board insulation board during construction?
Extruded board for exterior wall Materials prepared before construction include: interface agent, mesh cloth, anchor bolt, plastering mortar, bonding mortar XPS Plastic extruded board;
The construction tools of exterior wall extruded board include: trowel, wood washboard, internal and external corner trowel, proprietary serrated trowel two Meter guiding rule, electric mixer, brush, knife, pallet, stay wire, tape measure, impact drill, scissors, brush, sandpaper, hammer.
Construction process of external wall extruded board insulation board
1、 The base wall shall be treated. The wall must be cleaned and leveled. Where there are pits and bulges, the pits shall be filled with cement and the bulges shall be removed XPS The surface of extruded board shall be coated with special interface agent.
2、 Prepare the materials, prepare the adhesive paste, and connect the adhesive and water according to 5:1 Mix and place five It can be used in minutes, better in two Use up within hours. In the construction process, not every piece can be constructed according to the standard size, so it is necessary to equip electric heating wire to cut at any time to facilitate the construction of external wall insulation board.
3、 Paste the external wall extruded board insulation board, conduct interface treatment on the extruded board to increase the cohesiveness, coat the extruded board with adhesive mortar, and then drag and scrape it once with a special serrated trowel, and scrape off the excess adhesive mortar between the serrations. After the thick treatment, paste the extruded board flat on the external wall and slide it in place. When pasting, it should be gently and evenly squeezed, and a length should be prepared at any time 2m To flatten.
4、 When pasting the extruded insulation board of the exterior wall, it should be laid in staggered joints, with half of the board length staggered. The construction shall be carried out quickly. Before the extruded board is installed in place, the adhesive mortar shall not be skinned. The joints of the extruded board shall be tight and flat. The adhesive mortar shall not be applied on the side of the external wall insulation board.
5、 The construction process of the exterior wall plastic extrusion plate at the door and window openings and corners should use a whole plastic extrusion plate to cut out the openings without splicing. The exterior wall plastic extrusion plate should be pasted thick and spaced twenty-four After bonding and fixing for hours, polish to prevent displacement and dislocation of the extrusion plate.
6、 Install the fastener and paste the extruded plate twenty-four After 24 hours, drill holes with an impact drill and install plastic expansion anchor bolts according to the design requirements.
7、 Lay grid cloth, use stainless steel trowel, and evenly apply a layer of plaster mortar with an area slightly larger than that of a grid cloth on the surface of the external wall insulation board 3mm On the left and right, press the mesh cloth into the wet plaster mortar until the mesh cloth is completely covered with the exterior wall extrusion plate and the surface is polished.
exterior wall Extruded board insulation board Precautions for construction process:
one The bonding operation of extruded board shall be rapid, and the bonding glue shall not be skinned
two , extruded board pasting twenty-four After hours, install the expansion anchor bolt of the extruded plate
three Do not lay grid cloth in the rain
four , the grid cloth shall be continuous, and the width of wall wrapping from each side in both directions shall not be less than 200mm Reinforce the docking arrangement of mesh
five , curing after construction twenty-four In cold and humid climate, the curing time should be extended appropriately.
