Embodiment Construction

[0026] like figure 1 As shown, a sound insulation board with micro-ventilation of the present invention includes a board body 1, a board 3 and a clamping soft board 2 sandwiched between the board body 1 and the board 3. combine Figure 5-8 As shown, the board body 1, the board 3 and the clamping soft board 2 are all rectangular. A plurality of first silencing through holes 10 are spaced apart on the board body 1 , a plurality of second silencing through holes 5 are spaced apart on the plate 3 , and a plurality of ventilation holes 9 are spaced apart on the clamping flexible board 2 . The first silencing through holes 10 , the second silencing through holes 5 and the ventilation holes 9 are all evenly spaced in an array. The first silencing through hole 10 , the second silencing through hole 5 and the ventilation hole 9 are all circular holes or hexagonal holes.

[0027] Board body 1 and board 3 are pressed by a mixture of polypropylene short fibers, wood fibers, Portland c...

Abstract

The invention relates to the field of building materials, in particular to a sound insulation board with micro-ventilation. It includes a board body, a board, and a clamping soft board sandwiched between the board body and the board, and there is a first gap between the board body and the clamping soft board and between the board and the clamping soft board; There are a plurality of first silencing through holes, and a plurality of second silencing through holes are arranged at intervals on the plate, and the first silencing through holes and the second silencing through holes are distributed one by one; A plurality of ventilation holes are spaced apart on the upper side, and the ventilation holes are distributed alternately with the first and second noise-elimination through-holes. The invention has the effects of sound insulation and good micro-ventilation, and prevents dust from being brought in by strong winds.

Description

technical field [0001] The invention relates to the field of building materials, in particular to a sound insulation board with micro-ventilation. Background technique [0002] As we all know, during construction, especially field construction work, in order to catch up with the construction period, the construction is carried out overnight. The workers' work sheds are daily responsible for the tasks of living, canteen, study, meeting guests, etc., and the outdoor equipment does not stop for a moment, which brings The incoming noise has a huge impact. Since the work sheds are basically temporary, it is impossible to achieve the good noise resistance function of cement or other permanent buildings. Most of the materials used in the existing work sheds are wood boards, composite boards or plywood, and these boards have poor sound insulation effects. Although there are also sound insulation boards, the noise reduction through the sound insulation board and the reduction of the...
