Description

Technical Field

[0001] The utility model relates to the technical field of sound insulation boards, in particular to a concrete sound insulation board for highway sound barriers which is easy to install. Background Art

[0002] Noise barriers are installed along highways near residential or office areas to prevent the spread of sound and prevent passing vehicles from disrupting the lives and work of residents. Noise barriers can be constructed from a variety of materials, with foam aluminum sound-absorbing panels, concrete sound-isolating panels, and transparent acrylic sound-isolating panels being the most common.

[0003] The Chinese patent with patent number CN202023035544.1 discloses a lightweight concrete sound insulation board, including a concrete layer, one end of the concrete layer is provided with a splicing protrusion, the other end of the concrete layer is provided with a splicing groove, and both sides of the concrete layer are provided with an outer cladding board, and the inner surface of the outer cladding board is provided with multiple extension protrusions. A supporting frame is designed in the concrete layer, and a pair of extension rods are designed on each side of the supporting frame. During installation, the expansion screw is fixed to the designated ground position, one end of the expansion screw is passed through the lower threaded hole on the lower folding rod, and fixed with a nut, so that the entire concrete sound insulation board is installed more firmly, and when the board body is spliced longitudinally, the lower threaded hole on the lower folding rod can be aligned with the upper threaded hole on the upper folding rod of another sound insulation board, and fixed with bolts, and then combined with traditional mortar bonding to ensure that the connection between the sound insulation boards is more firm.

[0004] The concrete sound insulation board provided by the aforementioned patent, also known as a concrete sound insulation board, is installed by snapping it between adjacent I-shaped support rods and using a pressure plate to press it against the concrete sound insulation board, ensuring that the concrete sound insulation board is stable between the two support rods. However, existing concrete sound insulation boards are often manufactured without protection at the ends, which are the most vulnerable to damage. Therefore, when the pressure plate is pressed against the concrete sound insulation board during installation, it is easy to cause damage to the ends of the concrete sound insulation board. Utility Model Content

The concrete sound insulation board body 1 with this structure has high strength and is not easily damaged. In addition, a plurality of weight reduction holes 12 are evenly arranged on the inner side of the concrete sound insulation board body 1 from top to bottom. The weight reduction holes 12 are used to reduce the weight of the concrete sound insulation board body 1 and make the concrete sound insulation board body 1 have a better sound absorption effect. In addition, protective sleeves 2 are provided at both ends of the concrete sound insulation board body 1. The protective sleeves 2 are used to protect the two ends of the concrete sound insulation board body 1. Connecting rods 3 are provided in the weight reduction holes 12 at the top and bottom of the concrete sound insulation board body 1. The two ends of the connecting rods 3 are respectively connected to the two protective sleeves 2; the connecting rods 3 are used to stably fix the protective sleeves 2 on the concrete sound insulation board body 1.

[0026] like Figure 2 As shown, plugs 11 are symmetrically provided at both ends of the concrete sound insulation board body 1. The plugs 11 are used to be inserted into the inner side of the protective cover 2. The top and bottom ends of the concrete sound insulation board body 1 are respectively provided with splicing grooves 13 and splicing rods 14. The splicing grooves 13 and splicing rods 14 are aligned vertically and are used for splicing multiple concrete sound insulation board bodies 1 together.

[0027] like Figure 3 As shown, the protective cover 2 is made of metal material, and the top and bottom of the inner side of the protective cover 2 are aligned with the position of the weight-reducing hole 12, and the plug-in column 21 is convenient for matching with the connecting rod 3 to prevent the two ends of the connecting rod 3 from protruding from the outer surface of the protective cover 2. The plug-in column 21 is inserted into the inner side of the weight-reducing hole 12, and a through-hole 22 is provided in the middle of the plug-in column 21; the through-hole 22 is used for the connecting rod 3 to pass through the plug-in column 21. The side of the plug-in column 21 facing outward is recessed; this structure prevents the connecting rod 3 from protruding from the protective cover 2, which causes the connecting rod 3 to interfere with the bracket when the concrete sound insulation board body 1 is installed. A lifting rod 23 is provided at the top of the protective cover 2 for lifting the concrete sound insulation board when it is installed.

[0028] like Figure 4 As shown, a limiting end plate 31 is provided at one end of the connecting rod 3, and a nut 32 is connected to the other end. The limiting end plate 31 and the nut 32 are both placed on the inner side of the plug column 21, and the two ends of the connecting rod 3 do not protrude from the outer surface of the protective cover 2. This structure is convenient for tightening the two protective covers 2 by tightening the nut 32, so that the two protective covers 2 can be stably pressed on the two ends of the concrete sound insulation board body 1.

[0029] Working Principle: During use, two protective sleeves 2 are placed on both ends of the concrete sound insulation board body 1. A connecting rod 3 is passed through the protective sleeves 2 and the weight-reducing holes 12, and then through the other protective sleeve 2. The nuts 32 are then tightened to stabilize the two protective sleeves 2 at both ends of the concrete sound insulation board body 1, ensuring that both ends of the concrete sound insulation board body 1 are stably protected by the protective sleeves 2. During installation, the protective sleeves 2 are positioned inside the I-shaped support rods and then pressed against the protective sleeves 2 using a pressure plate. Compared with the prior art, the concrete sound insulation board body 1 of the present application is evenly provided with a plurality of weight-reducing holes 12 from top to bottom on the inner side. The weight-reducing holes 12 can effectively reduce the weight of the concrete sound insulation board. At the same time, protective sleeves 2 are provided at both ends of the concrete sound insulation board body 1. The protective sleeves 2 are pressed on the two ends of the concrete sound insulation board through the connecting rod 3, so that the two ends of the concrete sound insulation board body 1 are well protected and the problem of damage to the two ends of the sound insulation board will not occur. At the same time, the pressure plate is pressed on the protective sleeve 2 during installation, so the pressure plate does not directly contact the concrete sound insulation board body 1, and the two ends of the sound insulation board will not be damaged by the pressure plate.
