Elevator
hoistway noise treatment program using 50mm thick HOREQ-D2
sound-absorbing cotton plate, paste on the wall, and with expansion bolt
fixed; elevator shaft construction holes and cracks using HOREQ-D5
acoustic cotton filling, and then sealant or cement mortar Fill. Fourth,
the construction preparation 4.1 materials and equipment, labor
preparation 1, auxiliary tools: impact drill, no tooth saws, shovel,
rubber hammer, by foot, wallpaper knife box ruler and so on. (See the
table) 2, auxiliary materials: polymer mortar, sealant, cement mortar, ¡é
8 card solid nails. 4.2 Work Preparation All kinds of pre-buried
pipeline construction is completed, the masonry construction is
completed, elevation control line bombs in the wall, column. Fifth, the
construction process: grass-roots processing --- playing line ---
typesetting - cutting board --- security board --- fixed hole ---
caulking. Construction methods: 1, the primary treatment: the walls of
loose debris to clean up the dust, the walls of the uneven surface of
the wall plaster with plaster leveling (requirements of the original
wall flatness deviation of not more than 1 cm). 2, playing line:
According to the level of 1m control line pops up the horizontal axis of
the shaft wall, with two points into a line on both sides of the hanging
white line, with cement nail tension, according to the door pop wall
vertical line, in accordance with the specifications of acoustic panels
Pop-up grid lines. 3, typesetting: According to the pop-up horizontal
and vertical lines for typesetting, layout should be nice, neat and
consistent, arranged in the order of the level, up and down the wrong
seam, yin and yang should be done stubble, plate and adjacent can not
color difference between large , Especially for irregular beams and
columns to do a small patchwork uniform patchwork. 4, cutting board:
Cutter application wallpaper knife and ruler, to be careful to cut the
board, to ensure that the board flat can not afford to corner. 5, the
board: the construction of the elevator shaft using the car as a
vertical means of transport, elevator shaft construction hole and the
gap filling with HOREQ-D5 noise cotton plugging, and then sealant or
cement mortar filled. HOREQ-D2 surface of concave and convex
sound-absorbing cotton board with 20 thick polymer mortar paste, convex
side facing the shaft, according to the requirements from bottom to top
(using paste tile practice) followed by the installation of
sound-absorbing panels, sticky board to clear the overflow Knot mortar,
so that no plate between the "meet the gray." When the seam width is
more than 3 mm, it should be filled with HOREQ-D5 sound insulation
cotton with the corresponding thickness. When installing, check the
flatness and verticality of the sound-absorbing panel at any time. 6,
drilling fixed: ¡é 8 anchor reinforcement, a good sound-absorbing paste
in the paste, spacing 600mm hole with a hammer drill ¡é 8 to ensure that
the depth of the hole into the structural wall ¡Ý 50mm, while the depth
of sound insulation board to consider Thickness, you can enter the
plastic pipe and plastic pressure plate. The length of the expansion
bolt should be appropriate, not too long, too long will make the
expansion bolt loose is not strong, too short will make the expansion
bolt can not be fully open, the pressure plate can not achieve a fixed
role. Be sure to ensure that the plastic expansion tube fixed pressure
plate and plate connection, so that pressure plate embedded in the depth
of the board should be consistent. 6, to ensure the quality of measures
In order to better achieve the effect of sound-absorbing insulation,
sound-absorbing panels installed to take the following quality assurance
measures 6.1 Sound-absorbing panels in strict accordance with the
performance requirements of the following table approach..
