Problems solved by technology

At present, the sound insulation facilities that are often used are mainly sound insulation doors and windows. To achieve the effect of sound insulation, the sound insulation doors and windows must be closed for sound insulation. After closing the windows, people will be in a closed environment for a long time, which seriously affects people's health. In addition, one of the effects affecting sound-proof doors and windows is the sealing performance of doors, windows and installation walls. Water seepage in installation joints after installation without sub-frames also occurs from time to time, and at the same time, errors in civil engineering openings cause installation gaps Unevenness, and large deviations in the size of openings of the same specification, will also have a greater impact on the installation quality and construction progress
[0003] Existing soundproof doors and windows can achieve a certain ventilation effect after installing a window ventilator on the glass, but if the size of the ventilator itself is too small, it cannot meet the standard ventilation requirements; if double-layer soundproof doors and windows are used, The sound leakage area will increase, which will affect the sound insulation performance. At the same time, it will also reduce the lighting area of ​​the doors and windows, and the sealing of the joints of the installation slots will be poor. The production cost is high and the sound insulation effect is poor.

Embodiment 1

[0025] Example 1, such as figure 1 As shown, a sub-frame profile for ventilation and sound insulation includes a ventilation frame 2 partially pre-embedded in the upper wall 1 and a pre-embedded frame 4 pre-embedded in the lower wall 3, wherein the ventilation frame 2 and the pre-embedded frame 4 fixedly connected to form an opening frame; the ventilation frame 2 includes a main frame 5 pre-buried in the upper wall 1 and a sub-frame 6 fixedly connected under the main frame 5, and a buckle cover 7 is installed on the main frame 5 and the sub-frame 6 ; The main frame 5 and the sub-frame 6 are provided with a C-shaped groove, the top of the buckle cover 7 is a U-shaped groove, and the U-shaped groove is engaged with the C-shaped groove, and the bottom of the buckle cover 7 is an undercut structure. The resilient force formed by the radian of the middle part of 7 clamps the buckle cover 7 on the main frame 5 and the sub-frame 6; the buckle cover 7 is a double-layer structure, and ...

Embodiment 2

[0026] Embodiment 2: as figure 2 As shown, the difference from Embodiment 1 is that this case adopts a double-layer structure, that is, on the basis of Embodiment 1, the opening frames are arranged side by side, and the two are connected by a connecting frame 13 to form a double-layer sub-frame type. The flow direction of fresh air like figure 2 indicated by the arrow in .

[0027] Whether it is embodiment 1 or embodiment 2, when installing, the main frame 5, sub-frame 6, buckle cover 7 and damping heat insulation strip 8 are combined into a ventilation frame 2, and then ventilation holes are milled inside it to install the power frame. The fan 9 and the sound-absorbing material are then combined with the pre-embedded frame 4 to form an opening frame. Before the civil engineering plastering or wet work is completed, the opening frame is installed in the wall. After the civil engineering plastering and wet work are completed, Only part of the ventilation frame 2 is exposed,...

Abstract

The invention discloses a ventilating and sound insulating secondary frame sectional material which comprises a ventilating frame (2) embedded into an upper wall body (1), and an embedded frame (4) embedded into a lower wall body (3), wherein the ventilating frame (2) and the embedded frame (4) are fixedly connected to form a hole frame. According to the ventilating and sound insulating secondary frame sectional material, the structure in combination of the embedded ventilating frame and the embedded frame is adopted and effectively improves the tightness of the whole secondary frame sectional material and the installing wall bodies, and the problems of the prior art that the crack and water penetrating are generated during arranging a ventilating window can be effectively avoided; the ventilating and sound insulating secondary frame sectional material is convenient to arrange; the secondary frame sectional material is organically combined with a ventilating unit through the structure; and the defects of current double-layer ventilating sound insulating windows that a relatively large space is occupied, the cost is high, and the efficiency is low are overcame.

Description

technical field [0001] The invention belongs to the field of noise control, and in particular relates to an auxiliary frame profile for ventilation and sound insulation. Background technique [0002] With the continuous development of cities and transportation, the urban population continues to increase, and the high-noise distances in places such as residences, roads, and airports continue to shrink, resulting in people living in a noisy environment for a long time. At present, the sound insulation facilities that are often used are mainly sound insulation doors and windows. To achieve the effect of sound insulation, the sound insulation doors and windows must be closed for sound insulation. After closing the windows, people will be in a closed environment for a long time, which seriously affects people's health. In addition, one of the effects affecting sound-proof doors and windows is the sealing performance of doors, windows and installation walls. Water seepage in insta...
