Construction Measures of Noise and Noise
in Elevator
Noise reduction construction site for the residents near the elevator
shaft inside the wall. Third, the elevator shaft noise treatment program
using 50mm thick HOREQ-D2 sound-absorbing cotton board, 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 filled
Site preparation of a variety of embedded pipeline construction is
completed, 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 sound- 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 filling, 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.
