Embodiment Construction

[0018] The present invention will be described in detail below in conjunction with the accompanying drawings and examples.

[0019] Such as figure 1 As shown, the present invention includes two window frames 1 and 2 installed at a certain distance in a window hole, the distance between the two window frames 1 and 2 is about 130mm, and a window frame is arranged in the middle of the two window frames 1 and 2 respectively. Stiles 3, 4 that separate window frames 1, 2 into upper and lower parts. A fixed window glass 5 (as shown in Figure 2) is installed above the middle pole 3 positioned outside, and a glass shutter 6 is installed below the pole 3; A glass shutter 7 is installed above the pole 4 positioned indoors (as shown in Figure 3 Shown), two inward-opening type casement windows 8 are installed below the middle pole 4. Because the distance between the two window frames 1 and 2 is about 130mm, the glass shutters 6 and 7 are easy to install and operate flexibly. .

Abstract

The invention relates to breathing sound insulation window which consists of two window frames, center stem dividing each window, and inner, outer window installed between the frame and the center stem, featuring that: it includes a primary sound insulation channel set at the bottom of the two frames, the air inlet port of the primary sound insulation channel is set widthwisely on out side, and the air outlet port at inner side between the two frames, the air inlet port is set with a sealing block, a sound insulation channel is formed by sound insulation plate between the two air port; a secondary sound insulation channel sealing connected between the middle stem of the two frames with the air inlet port set at the bottom and the outlet port at the top, between the inlet and outlet port a reverse sound insulation channel is formed with baffle plates; outer winder of which the upper part is fixed glass window, and the lower parts glass back-shutter; inner glass window of which the upper parts is glass back-shutter and the lower parts a double sliding open window. The invention is of remarkable sound insulation effects and can be widely applied to various buildings.

Description

technical field [0001] The invention relates to a sound insulation window, in particular to a ventilation and sound insulation window. Background technique [0002] At present, urban traffic noise has become the main cause of environmental pollution. Due to the complexity of traffic noise sources, it is very difficult to control, and in some aspects there are almost no effective solutions. Urban traffic noise includes noise generated by highways, railways, urban railways, airports, etc., and noise barriers can be used to control traffic noise. Barriers have a good effect on noise reduction for low-rise buildings, and the effect of buildings above six floors is poor. The most harmful is usually around the tenth floor. In my country's large and medium-sized cities, most of the roads, railways, and urban railways are high-rise buildings, and the sound insulation of barriers is generally 10-15dB. Therefore, the effect of using barriers to control traffic noise is still low. There...
