Technical Field

[0001] The invention relates to the technical field of building construction, and in particular to a construction method of a sound insulation wall. Background Art

[0002] Hotel buildings pay great attention to the sound insulation effect in guest rooms, which directly affects the guests' living experience and quality of life. Conventional processes control the reverberation time in the room and ensure the sound insulation effect by setting acoustic decorative surfaces such as soft bags, perforated panels, and sound-absorbing panels.

[0003] Acoustic requirements are met by setting up sound insulation walls, and the panels are not restricted by the requirements of sound insulation finishing materials and any finishing materials can be selected.

[0004] At present, civil buildings have increasingly higher requirements for acoustic sound insulation. High-quality hotels require that the sound insulation performance in the room meet NIC50. However, the finishing materials in the room are often subject to sound insulation requirements, and the selection area is relatively small, mostly soft finishing materials. Soft finishing materials are not as good as hard decorative materials that match the style of the room, and the sound insulation effect is not as good as hard decorative materials. Therefore, traditional sound insulation coatings have poor sound insulation effect, easy peeling and cracking, and poor weather resistance, which makes it difficult to meet the hotel's sound insulation, aesthetics and other performance requirements.

[0028] The following describes the embodiments of the present invention through specific examples, and those skilled in the art can easily understand other advantages and effects of the present invention from the contents disclosed in this specification. The present invention can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present invention.

[0029] The following is combined with Figure 1 The present invention is described in further detail.

[0030] The embodiment of the invention discloses a construction method of a sound insulation wall.

[0031] Reference Figure 1 , a construction method of a sound insulation wall, comprising the following construction steps:

[0032] S1: Lay the upper and lower horizontal keels according to the ground finish and ceiling elevation line;

[0033] S2: Lay vertical keels between the upper horizontal keel and the lower horizontal keel along the set spacing, and install them on the corresponding upper horizontal keel and the lower horizontal keel through fixing parts;

[0034] S3: Lay the secondary keel on the vertical keel at the set interval;

[0035] S4: Lay a wire mesh 1 on the secondary keel;

[0036] S5: Fill the sound insulation cotton 2 between the steel mesh 1 and the vertical keel;

[0037] S6: Lay a flame retardant board 3 on the outside of the vertical keel for sealing;

[0038] S7: Lay the decorative panel 4 on the flame retardant panel 3.

[0039] The combined sound-absorbing wall is used to meet the acoustic sound insulation requirements. At the same time, the decorative panel 4 is not restricted by the sound insulation finishing materials, and hard finishing materials can be selected to meet the acoustic sound insulation requirements while ensuring the beautiful finishing.

[0040] The upper horizontal keel and the lower horizontal keel adopt U-shaped light steel keel. The U-shaped light steel keel has a U-shaped groove. The top and bottom of the vertical keel are installed in the U-shaped groove, and fixing the upper horizontal keel and the lower horizontal keel is firm and convenient.

[0041] Vertical purlins are laid between the upper horizontal purlins and the lower horizontal purlins at a horizontal interval of 400mm to form the purlin frame of the sound insulation wall.

[0042] The flame retardant board 3 uses a 12mm thick flame retardant base board to seal the horizontal keel, lower horizontal keel, vertical keel and auxiliary keel. The 12mm thick flame retardant board 3 has a strong load-bearing capacity, can effectively fix the keel, and enhance the overall stability of the wall; the thick flame retardant board 3 can provide better flame retardant performance, effectively prevent the spread of fire, and ensure the safety of the building; the thicker flame retardant board 3 can enhance the sound insulation performance of the wall, reduce noise transmission, and improve living comfort; the 12mm thick flame retardant board 3 is easy to cut and install, which is convenient for construction operations, improves construction efficiency, and can ensure the safety, stability and beauty of the wall structure.

[0043] Sound insulation cotton 2 uses 25mm thick 48KG / m 3 Single-sided tin foil glass wool. Place a damping sheet on the steel mesh 1 to reduce vibration; cut the sound insulation cotton 2 according to the wall size, wrap the sound insulation cotton 2 tightly around the damping sheet, and fix the sound insulation cotton 2 with a cable tie or aluminum foil tape to ensure it is firm.

[0044] An open panel bottom box is installed on the vertical keel, and the contact part between the glass wool and the open panel bottom box is sealed with a non-rigid sealant. The non-rigid sealant is a sealing material with a certain elasticity or flexibility, which can be deformed with the shape of the sealing surface, is not easy to flow, and has a certain adhesiveness. Silicone sealant, end-silane polyether sealant, polysulfide sealant, polyurethane sealant, etc. can be used. In the installation of the sound insulation wall, the non-rigid sealant bonds the sound insulation cotton 2 to ensure the close fit between the sound insulation cotton 2 and the keel, thereby improving the sound insulation effect.

[0045] The wire mesh 1 uses a 50*50*0.8mm galvanized wire mesh 1 as the skeleton back mesh of the secondary keel, and the corners of the wire mesh 1 are fixed to the secondary keel using mounting parts. The mounting parts are V-shaped clips made of steel wire. When fixing, first disassemble one end of the wire mesh 1 into an L angle, and then use the steel wire to make a V-shaped clip for fixing. Disassemble one end of the wire mesh 1 (50 mm away) into an L angle to facilitate turning and overlapping. Use a steel wire with a diameter of not less than 1.5 mm to make a V-shaped clip, first fix the wire mesh 1, and punch or inject the anchors in a plum blossom shape to ensure that it is firmly fixed.

[0046] The fixing parts are U-shaped mounting clips, which are fixed to the upper horizontal keel and the lower horizontal keel.

[0047] Put the vertical keel into the U-shaped mounting clamp to complete the fixation. The U-shaped mounting clamp is simple in design and easy to operate. It can quickly fix the vertical keel between the upper and lower horizontal keels to improve construction efficiency. The U-shaped mounting clamp can fit the keel surface tightly and fix the keel firmly through bolts and other fasteners to ensure that the wall structure is stable and not easy to loosen. The U-shaped mounting clamp can be applied to keels of different specifications and sizes, and can be flexibly adjusted to meet various construction needs. Using the U-shaped mounting clamp to fix the keel does not require a lot of welding or pasting, saving material costs and reducing the weight of the wall. In the soundproof wall, the U-shaped mounting clamp can effectively fix the keel to avoid gaps between the keels, thereby ensuring the sound insulation performance of the wall.

[0048] The V-shaped clip has a unique design and can be tightened with only one bolt. Compared with the traditional three-bolt installation method, the installation efficiency is improved; the connection characteristics of the V-shaped clamp enable it to be installed in a small space, and the connection end is compactly designed to effectively save space; the V-shaped structure can fit tightly to the surface of the keel, flexibly adapt to the needs of different sizes and specifications, and effectively prevent loosening or leakage; it can work stably in extreme environments to ensure long service life and safety.

[0049] The vertical keel adopts 50-type light steel vertical keel. Choosing 50-type light steel vertical keel can provide stable support for the sound insulation wall.

[0050] In this embodiment, the decorative panel 4 can be selected in a corresponding color or style according to the hotel installation style, which solves the problems of poor sound insulation effect, easy peeling and cracking, and poor weather resistance of the sound insulation coating.

[0051] This article uses specific examples to illustrate the principles and implementation methods of the present invention. The description of the above embodiments is only used to help understand the method of the present invention and its core ideas. The above are only preferred implementation methods of the present invention. It should be pointed out that due to the limitations of textual expression, there are objectively infinite specific structures. For ordinary technicians in this technical field, without departing from the principles of the present invention, they can also make several improvements, modifications or changes, and can also combine the above technical features in an appropriate manner; these improvements, modifications, changes or combinations, or the direct application of the inventive concept and technical solution to other occasions without improvement, should be regarded as the protection scope of the present invention.
