Description

Technical Field

[0001] This utility model relates to the technical field of construction noise barrier facilities, and in particular to a construction noise barrier facility for highway bridge engineering. Background Technology

[0002] Sound barriers are mainly used for sound insulation and noise reduction of highways, expressways, elevated composite roads and other noise sources. They are divided into reflective sound barriers that are purely sound insulation and composite sound barriers that combine sound absorption and sound insulation. The latter is a more effective sound insulation method. During the construction of highway bridges, a lot of noise is easily generated, so sound barriers need to be set up to block the noise and prevent noise pollution during use. In existing technologies, sound barriers are typically installed on both sides of highways or bridges using mounting posts. However, when installing sound barriers using mounting posts, gaps can easily exist between the bottom of the sound barrier and the ground, affecting the sound insulation effect. This is especially true during highway construction, where uneven road surfaces make it difficult to ensure a tight contact between the sound barrier and the ground, further impacting the sound insulation effect. Therefore, this paper proposes a sound barrier system for highway and bridge construction to address these issues. Utility Model Content

[0003] The purpose of this utility model is to solve the problems existing in the above-mentioned background technology and to propose a sound barrier facility for highway bridge construction.

[0004] The technical problem to be solved by this utility model is to provide a sound barrier facility for highway bridge construction to solve the problem that the existing sound barrier facilities for highway bridge construction do not have a tight contact with the ground, which affects the sound insulation effect.

[0005] To solve the above-mentioned technical problems, this utility model provides the following technical solution: A sound barrier facility for highway bridge construction includes mounting columns, supporting base rods, and sound barrier plates. The mounting columns include a pre-embedded end and an installation end. Installation grooves are provided on both the left and right sides of the installation end of the mounting column. Supporting base rods are installed at the bottom inner side of the installation groove between two mounting columns. A sound barrier plate is installed above the installation groove between two mounting columns by means of an installation component. A positioning plate is fixedly provided on the outer bottom of the installation groove. The supporting base rod includes an internal groove, sliders, and lifting bars. The internal groove is provided on the inner side of the supporting base rod. Multiple sliders are slidably arranged in the internal groove. A lifting bar is fixedly installed in the center of the bottom surface of the sliders and extends through the bottom surface of the supporting base rod.

[0006] Preferably, the distance between the positioning plate and the inner side of the mounting groove is equal to the thickness of the support base rod.

[0007] Preferably, a through groove is provided in the center of the bottom surface of the support base rod, and the width of the through groove is equal to the thickness of the lifting bar, and the width of the through groove is less than the width of the inner groove.

[0008] Preferably, the width of the slider is equal to the width of the inner groove, and the slider can slide up and down along the inner groove. When the slider slides to the bottom of the inner groove, the bottom horizontal height of the lifting bar is equal to the bottom surface horizontal height of the supporting base rod.

[0009] Preferably, the sliders inside the internal groove are in contact with each other, and the lifting bars at the bottom of the sliders are also in contact with each other.

[0010] Preferably, the mounting end includes an L-shaped rotating rod and mounting holes. The L-shaped rotating rod is rotatably positioned above and below the mounting groove, and the mounting holes are located at the four corners of the outer surface of the sound baffle.

[0011] Preferably, the diameter of the mounting hole is equal to the diameter of the L-shaped rotating rod, and the height of the mounting hole is not less than the height of the outer end of the L-shaped rotating rod.

[0012] Preferably, when the bottom of the sound baffle is attached to the upper surface of the support rod, the L-shaped rotating rod and the mounting groove rotate at the bottom of the corresponding mounting hole, and the length of the bent part of the L-shaped rotating rod from the inside of the mounting groove is equal to the thickness of the sound baffle.

[0013] Preferably, the outer surface of the sound baffle is provided with multiple sound inlet holes, and the center of the interior of the sound baffle is filled with sound-absorbing cotton.

[0014] Preferably, the sound inlet extends into the sound-absorbing cotton.

[0015] In the above scheme, by setting up a support base rod and a sound baffle, during installation, the pre-embedded ends of the bottom of the two mounting columns are buried on both sides of the road according to the length of the support base rod, so that the road surface level is equal to the bottom level of the mounting groove. Then, the support base rod is inserted into the bottom of the mounting groove of the two mounting columns, so that the support base rod is between the mounting groove and the positioning plate. The positioning plate positions the support base rod. Then, the sound baffle is installed in the mounting groove between the two mounting columns through the installation end, and the sound baffle is attached to the upper surface of the support base rod, completing the installation. Under the gravity of the slider and the lifting bar inside the support base rod, the slider slides in the internal groove, so that the lifting bar contacts the upper surface of the road surface. When the ground is uneven, the horizontal height of the different lifting bars extending from the support base rod is different, which makes it convenient for the lifting bars to seal the gap between the bottom surface of the support base rod and the ground, reducing the sound transmission effect at the bottom gap and ensuring the sound insulation effect.

[0016] In the above solution, by setting an installation end, when installing the sound baffle, first rotate the L-shaped rotating rod so that the outer end of the L-shaped rotating rod faces upward. Then, align the four mounting holes on the sound baffle with the four L-shaped rotating rods on the two mounting columns, and insert the sound baffle into the mounting groove between the two mounting columns. At this time, the bottom surface of the sound baffle is attached to the upper surface of the supporting base rod, and the rotating part of the L-shaped rotating rod is below the corresponding mounting hole. Then rotate the L-shaped rotating rod so that the bent part of the outer end of the L-shaped rotating rod faces downward towards the mounting hole, thereby achieving the effect of locking the sound baffle in the mounting groove. The installation is simple and convenient.

[0017] In the above solution, by setting inlet holes and sound-absorbing cotton, the inlet holes face the construction side when the sound baffle is installed. The noise generated during construction enters through the inlet holes and is absorbed by the sound-absorbing cotton, reducing the spread of noise and reducing noise pollution.

[0026] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an embodiment of this utility model provides a sound barrier facility for highway bridge construction, including an installation column 1, a support base rod 2, and a sound barrier plate 3. The installation column 1 includes a pre-embedded end and an installation end. The installation end of the installation column 1 has installation grooves 101 on both the left and right sides. The support base rod 2 is installed at the bottom of the inner side of the installation groove 101 between two installation columns 1. The sound barrier plate 3 is installed above the installation groove 101 between two installation columns 1 through an installation component. A positioning plate 102 is fixedly installed on the outer side of the bottom of the installation groove 101. The support base rod 2 includes an internal groove 201, a slider 202, and a lifting bar 203. The internal groove 201 is provided on the inner side of the support base rod 2. Multiple sliders 202 are slidably arranged in the internal groove 201. A lifting bar 203 is fixedly installed in the center of the bottom surface of the slider 202, and the lifting bar 203 passes through the bottom surface of the support base rod 2.

[0027] In this embodiment, the distance between the positioning plate 102 and the inner side of the mounting groove 101 is equal to the thickness of the support rod 2, so that the support rod 2 can be embedded in the positioning plate 102 in the mounting groove 101. The positioning plate 102 supports the support rod 2, ensuring the stability of the support rod 2 after installation.

[0028] In this embodiment, a through groove is provided in the center of the bottom surface of the support rod 2, and the width of the through groove is equal to the thickness of the lifting bar 203, and the width of the through groove is less than the width of the inner groove 201, so as to ensure the stable lifting of the lifting bar 203 and prevent the slider 202 from falling out of the through groove.

[0029] In this embodiment, the width of the slider 202 is equal to the width of the inner groove 201, and the slider 202 can slide up and down along the inner groove 201. When the slider 202 slides to the bottom of the inner groove 201, the bottom horizontal height of the lifting bar 203 is equal to the bottom surface horizontal height of the support rod 2, ensuring the stability of the lifting bar 203.

[0030] In this embodiment, the sliders 202 inside the internal groove 201 are in contact with each other, and the lifting bars 203 at the bottom of the sliders 202 are also in contact with each other, reducing the sound from passing through the gaps between the lifting bars 203.

[0031] By setting up a support base rod 2 and a sound baffle 3, during installation, the pre-embedded ends of the bottom of the two mounting columns 1 are buried on both sides of the road according to the length of the support base rod 2, so that the road surface level is equal to the bottom level of the mounting groove 101. Then, the support base rod 2 is inserted into the bottom of the mounting groove 101 of the two mounting columns 1, so that the support base rod 2 is between the mounting groove 101 and the positioning plate 102. The positioning plate 102 positions the support base rod 2. Finally, the sound baffle 3 is installed in the mounting groove between the two mounting columns 1 through the installation end. Within 101, the sound baffle 3 is attached to the upper surface of the support base rod 2, completing the installation. Under the gravity of the slider 202 and the lifting bar 203 inside the support base rod 2, the slider 202 slides in the inner groove 201, so that the lifting bar 203 contacts the upper surface of the road surface. When the ground is uneven, the horizontal height of different lifting bars 203 extending out of the support base rod 2 is different, which makes it convenient for the lifting bar 203 to seal the gap between the bottom surface of the support base rod 2 and the ground, reducing the effect of sound transmission from the bottom gap and ensuring the sound insulation effect.

[0032] Reference Figure 1 , Figure 2 and Figure 5 As shown, in this embodiment, the mounting end includes an L-shaped rotating rod 4 and mounting holes 301. The L-shaped rotating rod 4 is rotatably disposed above and below the mounting groove 101, and the mounting holes 301 are opened at the four corners of the outer surface of the sound baffle 3.

[0033] In this embodiment, the diameter of the mounting hole 301 is equal to the diameter of the L-shaped rotating rod 4, and the height of the mounting hole 301 is not less than the height of the outer end of the L-shaped rotating rod 4, so that the L-shaped rotating rod 4 can pass through the mounting hole 301 to realize the installation of the sound baffle 3.

[0034] In this embodiment, when the bottom of the sound baffle 3 is attached to the upper surface of the support rod 2, the L-shaped rotating rod 4 and the mounting groove 101 rotate at the bottom of the corresponding mounting hole 301. The length of the bent part of the L-shaped rotating rod 4 from the inner side of the mounting groove 101 is equal to the thickness of the sound baffle 3. This facilitates the positioning of the sound baffle 3 when the L-shaped rotating rod 4 rotates to face downwards, making installation convenient.

[0035] With the installation end provided, when installing the sound baffle 3, first rotate the L-shaped rotating rod 4 so that the outer end of the L-shaped rotating rod 4 faces upward. Then, align the four mounting holes 301 on the sound baffle 3 with the four L-shaped rotating rods 4 on the two mounting posts 1, and insert the sound baffle 3 into the mounting groove 101 between the two mounting posts 1. At this time, the bottom surface of the sound baffle 3 is attached to the upper surface of the support base rod 2, and the rotating part of the L-shaped rotating rod 4 is below the corresponding mounting hole 301. Rotate the L-shaped rotating rod 4 so that the bent part of the outer end of the L-shaped rotating rod 4 faces downward towards the mounting hole 301, thereby locking the sound baffle 3 into the mounting groove 101. The installation is simple and convenient.

[0036] Reference Figure 5 and Figure 6 As shown, in this embodiment, the outer surface of the sound baffle 3 is provided with a plurality of sound inlet holes 302, and the center of the interior of the sound baffle 3 is filled with sound-absorbing cotton 303.

[0037] In this embodiment, the sound inlet 302 extends into the sound-absorbing cotton 303, facilitating the entry of sound into the sound-absorbing cotton 303, which absorbs noise.

[0038] With the sound inlet 302 and sound-absorbing cotton 303 provided, when the sound baffle 3 is installed, the sound inlet 302 faces the construction side. The noise generated during construction enters through the sound inlet 302 and is absorbed by the sound-absorbing cotton 303, reducing the spread of noise and reducing noise pollution.
