Description

Technical Field

[0001] The utility model relates to a pipeline well protective wall, in particular to a heat-insulating and sound-insulating pipeline well protective wall. Background Art

[0002] At present, in multi-story or high-rise buildings, such as residential bathrooms or kitchens, there are generally sewer pipes, which are generally PVC pipes for discharging domestic sewage. Especially when flushing the toilet or discharging large amounts of water such as washing machine drainage, a lot of noise will be generated. This noise causes great trouble to the work, life and rest of the residents downstairs, especially in the quiet night or early morning, affecting the sleep quality of the residents downstairs. In addition, in commercial buildings, the PVC pipes used for drainage are generally exposed directly to the outside. Although large-volume drainage does not affect the sleep of the residents downstairs, cleaning staff often open windows for ventilation. When the temperature drops below zero at night in the cold winter in the north, the PVC pipes are easily frozen and cracked, causing bathroom leaks, which in turn causes economic losses.

[0003] In order to solve the above problems, the existing method of reducing noise is: in residential buildings, sound insulation cotton is generally wrapped around the outside of PVC pipes. In order to solve the resonance problem, a layer of aluminum foil resistance sheet can be wrapped around the outside of the PVC pipes first, and then sound insulation cotton is wrapped around them, which will produce a better sound insulation effect; while in commercial buildings, the outer wall of PVC pipes is generally wrapped with insulation cotton to avoid the problem of pipes freezing and cracking caused by sub-zero temperatures.

[0004] However, the above method has the following problems: since the PVC pipes need to be wrapped with aluminum foil resistance sheets, sound insulation cotton or thermal insulation cotton, the construction is troublesome, takes a long time, and is not beautiful. The tops of the bathroom and kitchen can be covered by suspended ceilings, but the pipes vertically against the wall are exposed to the outside, and it is still necessary to manually build pipe wells to complete the shielding and beautification of the pipes; although prefabricated pipe wells are also installed in the prior art, and the water supply and drainage pipes are installed in the pipe wells, the pipe wells do not have a sound insulation function. Utility Model Content

[0005] The purpose of the present invention is to address the above-mentioned defects of the prior art and to provide a thermal insulation and sound insulation pipe well wall, which not only improves the construction speed and has a beautiful appearance, but also has a good noise reduction effect, reducing the noise impact on residents downstairs. In addition, the good thermal insulation effect avoids the problem of pipe freezing and cracking caused by sub-zero temperatures in commercial buildings.

[0028] Specifically, refer to Figures 1-6 The utility model mentions a thermal insulation and sound insulation pipe well protective wall, which includes an upper prefabricated protective wall 1, a lower prefabricated protective wall 2, a first fixed plate 3, a quick connector 5, a second fixed plate 6, a third fixed plate 7, and a fourth fixed plate 8. The first fixed plate 3 and the second fixed plate 6 are fixedly connected on both sides of the upper prefabricated protective wall 1, and the third fixed plate 7 and the fourth fixed plate 8 are fixedly connected on both sides of the lower prefabricated protective wall 2. The lower end of the upper prefabricated protective wall 1 and the upper end of the lower prefabricated protective wall 2 are quickly connected by a quick connector 5. The upper prefabricated protective wall 1 and the lower prefabricated protective wall 2 adopt an L-shaped structure.

[0029] The first fixing plate 3 and the second fixing plate 6 are respectively provided with fixing holes 4 , and are connected to the wall outside the pipeline well by bolts passing through the fixing holes 4 .

[0030] Reference Figure 5 The sound absorbing panel 1.2 mentioned in the present invention is made of polyurethane foam, and the sound absorbing holes 1.2.1 and the raised parts 1.2.2 are evenly distributed on the sound absorbing panel 1.2.

[0031] Reference Figure 6 The quick connector 5 mentioned in the present invention includes a first inner connecting plate 5.1, a connecting shaft 5.2, a second inner connecting plate 5.3, a first support plate 5.4, a first outer connecting plate 5.5, a second support plate 5.6, and a second outer connecting plate 5.7. A connecting shaft 5.2 is fixedly installed between the first inner connecting plate 5.1 and the second inner connecting plate 5.3, and the extension lines of the first inner connecting plate 5.1 and the second inner connecting plate 5.3 are in a vertical connection relationship; the outer side of the first inner connecting plate 5.1 is connected to the first outer connecting plate 5.5 through the first support plate 5.4, and the outer side of the second inner connecting plate 5.3 is connected to the second outer connecting plate 5.7 through the second support plate 5.6.

[0032] The first supporting plate 5.4 is located in the middle of the first inner connecting plate 5.1 and the first outer connecting plate 5.5, separating two connecting sleeves, and clamping the end of the prefabricated protective wall through the connecting sleeves.

[0033] In addition, installing reinforcing ribs 1.5 at the inner bend of the middle part of the prefabricated retaining wall prepared in the factory can improve the connection strength of the prefabricated retaining wall.

[0034] When the present invention is used, when the pipe well is located at the corner of two walls, the heat-insulating and sound-proof pipe well guard wall mentioned in the present invention is moved to the corner. Specifically, taking the quick connection of two sets of prefabricated guard walls as an example, first install the lower prefabricated guard wall 2, and respectively pass the bolts through the fixing holes through the third fixing plate 7 and the fourth fixing plate 8 to connect and fix it to the two walls; then, install the quick connector 5 on the upper end of the lower prefabricated guard wall 2, clamp the upper end of the lower prefabricated guard wall 2 through the connecting sleeve formed at one end of the quick connector 5, and then insert the lower end of the upper prefabricated guard wall 1 into the connecting sleeve formed on the upper part of the quick connector 5, so as to quickly achieve fixation, and then fix it with bolts. On the two walls; since the inner side of the wall body 1.1 of the upper prefabricated wall 1 and the lower prefabricated wall 2 is provided with a sound-absorbing panel 1.2, the noise of large-capacity drainage can be effectively absorbed. Then, by installing sound insulation cotton 1.3 on the outer side of the wall body 1.1, the noise transmitted can be effectively absorbed, reducing the noise impact on the residents downstairs; in addition, a flame-retardant heat-insulating board 1.4 is installed on the outer side of the sound insulation cotton 1.3, which can play a flame-retardant and heat-insulating effect. Magnesium oxide fireproof board is installed outside the flame-retardant heat-insulating board 1.4, which can facilitate the decoration of the outer side of the magnesium oxide fireproof board. Of course, magnesium oxide fireproof board can also be installed on the innermost side to play a more solid fixing role. The utility model not only improves the construction speed and has a beautiful appearance, but also has a good noise reduction effect, reducing the noise impact on the residents downstairs. In addition, the good heat-insulating effect avoids the problem of pipe freezing and cracking caused by sub-zero temperatures in commercial buildings.

[0039] The difference from Example 1 or 2 is:

[0040] The prefabricated protective wall mentioned in this embodiment adopts a U-shaped structure, which is suitable for the case where the pipeline is located on a wall. The upper prefabricated protective wall 1 and the lower prefabricated protective wall 2 are directly installed and fixed on the wall to achieve sound insulation and heat preservation treatment of the pipeline well.

[0042] The difference from Example 3 is:

[0043] The prefabricated protective wall mentioned in this embodiment can also adopt a rectangular structure, which is suitable for situations where the pipeline is not close to the wall. The pipeline can be directly wrapped with the rectangular structure to achieve sound insulation and heat preservation treatment of the pipeline.
