Abstract
Description
Technical Field
[0001] This utility model relates to an installation structure for a sound insulation panel, and more particularly to an installation structure for a sound barrier panel, a steel structure sound insulation cover, and a sound insulation panel suitable for use on both sides of a road. Background Technology
[0002] Noise barriers are a common and effective noise reduction measure used in urban traffic and industrial noise areas. A noise barrier consists of a foundation, columns, barrier panels, and installation accessories.
[0003] Because H-beams have good resistance to bending and deformation, most sound barriers use H-beams as their columns.
[0004] Currently, most sound barriers are installed using an insert method, where the sound barrier panel is inserted into the top opening of an H-beam steel column. A sealing strip is then inserted into the space between the sound barrier panel and the H-beam flange for fixation. However, when the distance between the H-beam flange and the sound barrier panel is large, the inserted sealing strip is insufficient to stabilize the panel. Therefore, a steel plate parallel to the sound barrier panel needs to be welded to the web of the H-beam, and then sealing material is filled between this steel plate and the sound barrier panel. The advantages of this method are simple installation and low material usage. The disadvantages are that the sound barrier panel is held in place by the sealing strip, which has poor clamping performance. Furthermore, stability is poor when the sealing strip ages or is affected by natural wind and traffic, making the sound barrier panel prone to significant swaying.
[0005] Another common approach is to drill holes in the web plate and then connect angle steel with bolts to clamp the sound barrier panel. This method can securely fix the sound barrier panel and is less constrained by site conditions, such as installation deviations of the column steel. The disadvantage is that it consumes a lot of material. When the thickness of the sound barrier panel decreases, the distance between the sound barrier panel and the angle steel increases, requiring larger angle steel for clamping. Furthermore, as the side length of the clamping edge of the angle steel increases, the clamping force will decrease accordingly with the same number of bolts.
[0006] Therefore, it is necessary to develop a fixing device that can be installed quickly, continuously pressurized to fix the sound barrier panels, and keep the sound barrier panels stable for a long time. Summary of the Invention
[0007] The technical problem to be solved by this utility model is to provide an installation structure for a sound barrier that can improve the installation efficiency of the sound barrier panel, enhance the sealing performance and long-term stability of the sound barrier panel.
[0008] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows:
[0009] The installation structure of this utility model for a sound barrier includes a vertically arranged sound barrier plate, an H-beam clamping the sound barrier plate, and a fastening assembly for fixing the sound barrier plate. The fastening assembly consists of bolts and a bent steel plate. The bent steel plate is placed between the outer side of the sound barrier plate and the outer flange of the H-beam. Bolts pass through threaded holes in the outer flange, pressing the bent steel plate against the outer side surface of the sound barrier plate's side area. When the bolts are tightened, the bent steel plate fixes the sound barrier plate between the inner flange of the H-beam and the bent steel plate.
[0010] The bent steel plate is composed of an outer plate, a connecting plate, an inner plate, and a side plate, which are integrally structured. The outer plate has a through hole, and the threaded hole is located on the outer flange of the H-beam opposite to the through hole. The connecting plate connects the inner plate and the outer plate. The side plate is placed on the side of the sound barrier plate. The inner plate is pressed against the outer surface of the side area of the sound barrier plate by bolts passing through the threaded hole and the through hole in sequence.
[0011] A nut is fitted onto each bolt between the outer plate and the outer flange plate and between the outer flange plate and the bolt nut to lock the bolt in place.
[0012] A certain gap is left between the side end face of the sound barrier plate and the web of the H-beam.
[0013] The thickness of the bent steel plate is 2mm-4mm, and its width along the length of the sound barrier is 30-50mm.
[0014] This invention provides a convenient, quick, and stable installation structure for sound barrier panels. Furthermore, compared to existing installation methods, while using the same materials, the sound barrier panels are secured using fastening components that allow them to be inserted from the front of the H-beam column without falling out. It can accommodate installation from two directions (one is by inserting from directly above the H-beam as in the existing method, and the other is by inserting at an angle from the front of the H-beam between the two flanges).

[0019] like Figure 1 , 2 As shown, the installation structure of the sound barrier of this utility model adopts a relatively simple structure to install the sound barrier panel 1. The sound barrier panel 1 has good stability when installed, and is convenient for maintenance, inspection and disassembly. During installation, the sound barrier panel 1 can be installed vertically by inserting it into the H-beam 2 from directly above it, according to the existing technology; or the sound barrier panel 1 can be installed by first placing the bottom of the sound barrier panel 1 at an angle between the inner flange plate 22 and the outer flange plate 23 of the H-beam 2, and then installing it by straightening the sound barrier panel 1. The latter method is easier, less labor-intensive and safer, and can also reduce the auxiliary equipment required for installation (such as large elevators).
[0020] The web 21 of the H-beam 2 used in this invention is slightly longer than that of the H-beam 2 in the prior art. The H-beam is vertically fixed to the base on which the sound barrier plate 1 needs to be installed. The H-beam 2 is used to support and hold the sound barrier plate 1. When the sound barrier plate 1 is vertically placed into the H-beam 2, the fastening components in the installation structure of this invention can firmly press and fix the side of the sound barrier plate 1 in the web groove of the H-beam 2 (i.e., the space between the inner flange plate 22 and the outer flange plate 23).
[0021] The fastening assembly for fixing the sound barrier panel 1 of this utility model consists of bolts 4 and bent steel plates 3. The bent steel plates 3 are placed between the outer side of the sound barrier panel 1 and the outer flange plate 23 of the H-beam 2. The bent steel plates 3 are pressed against the outer side of the sound barrier panel 1 by the bolts 4 passing through the threaded holes provided on the outer flange plate 23. When the bolts 4 are tightened, the side area of the sound barrier panel 1 is fixed between the inner flange plate 22 of the H-beam 2 and the bent steel plates 3.
[0022] The bent steel plate 3 preferably has the following structure, which consists of an outer plate 31, a connecting plate 32, an inner plate 33, and a side plate 34 in an integral structure (the side pointing towards the outer flange plate 23 of the H-beam 2 is the outer side, and the side pointing towards the sound barrier plate 1 to be installed is the inner side). The outer plate 31 and the inner plate 33 are parallel and are spaced a certain distance apart, which can be determined according to the length of the bolts 4 used. The connecting plate 32 is parallel to the side plate 34 and serves as a transition plate connecting the outer plate 31 and the inner plate 33. The side plate 34 extends from the side of the inner plate 33 toward the sound barrier plate 1 and is placed between the side end face of the sound barrier plate 1 and the web plate 21 of the H-beam 2. The side plate 34 can be used for lateral positioning of the sound barrier plate 1.
[0023] The thickness of the bent steel plate 3 is in the range of 2mm-4mm, preferably 2mm, and its width in the length direction of the sound barrier plate 1 is in the range of 30mm-50mm, preferably 40mm.
[0024] The outer plate 31 is provided with a through hole, and the threaded hole is located on the outer flange plate 23 of the H-beam 2 at a position opposite to the through hole. When the sound barrier plate 1 is placed into the web groove of the H-beam 2, the inner plate 33 is pressed against the outer side surface of the side area of the sound barrier plate 1 by the bolts 4 passing through the threaded hole and the through hole in sequence. Tightening the bolts 4 can move the sound barrier plate 1 and fix it between the inner plate 33 and the inner flange plate 22 of the H-beam 2.
[0025] After tightening bolt 4, tighten the multiple fastening nuts 5 that were previously fitted onto bolt 4 to prevent bolt 4 from loosening. Preferably, this invention provides two fastening nuts 5: one between the outer plate 31 and the outer flange plate 23, and the other between the outer flange plate 23 and the bolt nut.
[0026] When the angle between the inner flange plate 22 and the web plate 21 of the H-beam 2 (referred to as the flange angle α) is similar in size to the side angle of the sound barrier plate 1 (referred to as the barrier angle β), the side plate 34 of the bent steel plate 3 can be placed against the web plate 21. When the flange angle α is an arc angle and the barrier angle β is a right angle, a certain gap can be set between the side end face of the sound barrier plate 1 and the web plate 21 of the H-beam 2.
[0027] Several mounting positions can be provided on the side (along its height direction) of a sound barrier panel 1, and each mounting position only requires one fastening component of this utility model.
[0028] To further reduce noise, rubber pads 6 can be installed between the inner panel 33 and the sound barrier panel 1 and between the sound barrier panel 1 and the inner flange panel 22, respectively.
