Description
Technical Field
[0001] The utility model relates to the technical field of railway sound shielding devices, in particular to a fully enclosed railway sound barrier. Background Art
[0002] Railway transportation is a widely used mode of transportation. While providing convenient transportation, it also generates a lot of traffic noise pollution. In order to solve this problem, sound barriers can be laid outside the railway to block the noise generated by the passing trains.
[0003] Existing railway sound barriers adopt a square or arc-shaped fully enclosed structure, which is composed of support beams installed along the railway line and shielding panels laid between the support beams. During installation, the support beams are first fixed and installed, and then the panels are laid on each support beam, and finally fixed on the top by bolts, connecting strips and other connectors. This method can make the entire exterior of the barrier a complete smooth surface composed of panel laying, which is more aesthetically pleasing, but because the panel is located on the upper surface of the support beam, it only relies on connectors for fixation, which will have the risk of falling off during long-term use. For this reason, the utility model proposes a clip-on railway fully enclosed sound barrier. Utility Model Content

[0030] like Figure 1-8 As shown, a fully enclosed railway sound barrier proposed by the utility model includes support beams 1 installed at equal intervals along the railway line. The figure takes two support beams 1 as an example for explanation.
[0031] The closed sound barrier includes a plurality of sound insulation panels 2 which are laid along the circumferential surface of the supporting beam 1, a sealing spacer 4 which acts as an elastic barrier between the sound insulation panels 2, and a light-transmitting plate 3 which is fixed to the top surface of the supporting beam 1 by bolts.
[0032] like Figure 5 As shown, the support beam 1 is provided with a panel slot 11 and a pair of placement slots 12 connected to the panel slot 11 .
[0033] like Figure 4As shown, a block 21 is integrally fixedly connected to the end of the sound insulation panel 2 and can enter the panel slot 11 through the placement slot 12 and slide in the panel slot 11 . Figure 3 This is a schematic diagram of the first sound insulation panel 2 being installed to the end of the supporting beam 1 through the sliding fit between the clamping block 21 and the panel clamping slot 11. In this way, all the sound insulation panels 2 can be installed in place in sequence.
[0034] like Figure 6 As shown, the sealing spacer 4 includes a middle portion 41, a T-shaped end 42 integrally provided at one end of the middle portion 41, and an L-shaped end 43 integrally provided at the other end of the middle portion 41. Figure 7 As shown, a sealing member slot 111 for horizontal insertion of the sealing spacer 4 is provided on the inner wall of the panel slot 11, and the T-shaped end 42 and the L-shaped end 43 are horizontally inserted into the two ends of the sealing member slot 111 respectively, and the L-shaped end 43 is designed to prevent the sound insulation panel 2 from blocking the insertion path of the sealing spacer 4 after the sound insulation panel 2 is installed.
[0035] like Figure 8 As shown, the end of the sound insulation panel 2 is integrally provided with a covering block 22 that can be attached to the outer annular surface of the supporting beam column 1. The covering block 22 allows the sound insulation panel 2 to completely cover the outer annular surface of the supporting beam column 1, so that the outer surface of the barrier formed by the overall paving also has the smooth surface effect of the traditional connection using connecting pieces. Figure 8 As shown, a notch 211 for the sealing spacer 4 to be inserted into is provided on one side of the clamping block 21 , so that the sealing spacer 4 can enter the notch 211 to ensure that the adjacent sound insulation panels 2 can be completely assembled.
[0036] Both ends of the light-transmitting plate 3 are respectively fixedly connected to the top surfaces of the adjacent supporting beams 1 by bolts.
[0037] The working principle of this embodiment is: during installation, the support beams 1 are first installed in a traditional manner, and each two adjacent support beams 1 form a group and are installed along the railway line. The figure shows one group. Figure 3 and Figure 4 First, insert the block 21 at the end of the first sound insulation panel 2 into the panel card slot 11 through the placement slot 12 and slide it to the end of the supporting beam column 1 shown in the figure, and then insert the first sealing spacer 4 horizontally into the sealing spacer card slot 111 on the upper side of the sound insulation panel 2 to achieve isolation. Then install the second sound insulation panel 2 and the sealing spacer 4 in the same way, and repeat this process until the sound insulation panel 2 and the sealing spacer 4 are installed. Figure 1 After the two ends of the supporting beam 1 are laid, the light-transmitting plate 3 is finally covered on the top surface of the supporting beam 1 and fixed by bolts. This installation method of the light-transmitting plate 3 is the same as the traditional method, but because it is located on the top surface of the supporting beam 1, most of its own gravity is borne by the supporting beam 1, so it is less affected by slippage caused by factors such as vibration and gravity.
[0038] In summary, the special structural design of the sound insulation panel 2 and the supporting beam 1 can realize the snap connection between the two, so as to solve the problem of easy slipping in the traditional connection using connectors, and the installation is convenient; and the design of the covering block 22 can make the sound insulation panel 2 completely cover the outer annular surface of the supporting beam 1, so that the outer surface of the barrier paved as a whole also has the smooth surface effect of the traditional connection using connectors; the sealing spacer 4 plays an elastic barrier role between adjacent sound insulation panels 2, which can improve the buffering and shock absorption effect of the barrier in a vibration environment; the design of opening a notch 211 on one side of the block 21 allows the sealing spacer 4 to enter the notch 211 to ensure that the adjacent sound insulation panels 2 can be completely spliced.
[0039] The above-mentioned specific embodiments are only several optional embodiments of the present invention. Based on the technical solution of the present invention and the relevant inspiration of the above-mentioned embodiments, those skilled in the art can make various alternative improvements and combinations to the above-mentioned specific embodiments.
