Description

Technical Field

[0001] The invention relates to the technical field of sound barriers, and in particular to a highway sound barrier foundation embedded component, a sound barrier and a construction method. Background Art

[0002] Highway sound barriers are a type of soundproofing facility used to reduce the impact of traffic noise on the surrounding environment. They are usually made of sound-absorbing materials, such as sound-absorbing panels, transparent or opaque soundproof panels, etc., and are installed on both sides of the highway or on the median strip to block and absorb the noise generated by vehicle traffic. These barriers can not only effectively reduce noise pollution and protect the quality of life of nearby residents, but also reduce driver auditory fatigue and improve driving safety.

[0003] When installing sound barriers on both sides of the highway, the embedded parts are usually installed first. After leveling, the columns are installed on the embedded parts with bolts. After the columns are correctly installed, the sound barrier screen is lifted slightly off the ground with a crane or scaffolding, and the screen is slowly lowered with auxiliary safety slings. The two ends of the product are embedded in the grooves of the H-shaped steel columns and lifted along the grooves to an appropriate height. The auxiliary safety slings are removed and the product is lifted down to the final height. The screen is adjusted to the final position and fixed.

[0004] The above process has the disadvantage of inconvenient construction, because the sound barriers need to be hoisted one by one and inserted downward from the top of the column, and a hoisting device is also needed during disassembly to remove each sound barrier board from top to bottom, so the operation is cumbersome and the efficiency is low.

[0060] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. It should be pointed out that the drawings are schematic and not drawn to scale. For the sake of clarity and convenience in the figures, the relative sizes and proportions of the parts shown in the figures are exaggerated or reduced in size, and any size is only exemplary and not restrictive.

[0061] See also Figure 1-Figure 5A highway sound barrier comprises: a mounting seat 2, a column 3 is arranged on the mounting seat 2, a barrier plate 4 is arranged between the columns 3, the mounting seat 2 comprises a mounting plate 201, a semi-arc groove 203 is opened in the middle of the mounting plate 201, and a fixed shaft 202 is fixedly installed in the semi-arc groove 203, and the fixed shaft 202 is located at the center of the semi-arc groove 203; the mounting plate 201 is opened with a first bolt hole 204 and a second bolt hole 205; the column 3 comprises an I-beam 301, a plug hole 302 is opened at the bottom end of the I-beam 301, and the fixed shaft 202 is rotatably connected to the I-beam In the socket 302 of the I-beam 301, the I-beam 301 is also provided with a third bolt hole 305 located above the socket 302; the mounting plate 201 and the I-beam 301 are fastened by the first fastening bolt 5, and the first fastening bolt 5 is passed through the first bolt hole 204 and the third bolt hole 305; the two side surfaces of the I-beam 301 are respectively provided with a first slot 303 and a second slot 304; one end of the barrier plate 4 is movably clamped in the second slot 304 of one of the I-beams 301, and the other end is movably installed in the first slot 303 of the other I-beam 301.

[0062] In the above technical solution, since the semi-arc groove 203 is provided on the mounting plate 201, when the I-beam 301 is rotated to a vertical state, one side of the I-beam 301 contacts the vertical surface in the semi-arc groove 203 of the mounting plate 201, thereby preventing the angle of the I-beam 301 from further expanding, thereby ensuring that the I-beam 301 and the bottom surface of the mounting plate 201 are in a vertical state.

[0063] The advantage of the above technical solution is that when installing the barrier plate 4, first rotate one of the I-beams 301 to make it in a vertical state, and then insert one end of the barrier plate 4 into the second slot 304 opened by the I-beam 301 in turn and clamp it. After each barrier plate 4 is installed, rotate the other I-beam 301 to make the other end of each barrier plate 4 inserted into the first slot 303 opened by the I-beam 301, so that the barrier plate 4 is stably installed between the two I-beams 301. During the entire operation, for the barrier plate 4 installed at a lower position, there is no need to use a lifting device to lift it above the column 3 and then insert it into the column 3, thereby simplifying the operation steps and making the construction more convenient.

[0064] The second stopper 308 and the first stopper 306 are respectively installed in the first slot 303 and the second slot 304 of the I-beam 301 ; the first stopper 306 and the second stopper 308 are arranged in an array on the I-beam 301 ; the first stopper 306 is provided with a trapezoidal slot 307 .

[0065] The function of the first stopper 306 and the second stopper 308 is to provide support for the barrier plate 4 when the barrier plate 4 is installed, and to keep the barrier plate 4 in a stable state after installation.

[0066] See also Figure 6-Figure 7 The barrier plate 4 includes a plate body 401, and the upper and lower sides of the end of the plate body 401 inserted into the second slot 304 are both provided with a first right-angle notch 402 and a second right-angle notch 403; the plate body 401 is movably installed with a movable rod 404 located at the first right-angle notch 402, one end of the movable rod 404 penetrates into the plate body 401, and the other end is fixedly installed with a trapezoidal block 405, and the shape and the direction of the inclined surface of the trapezoidal block 405 match the trapezoidal slot 307; the movable rod 404 is also sleeved with a first spring 406, and the two ends of the first spring 406 are respectively fixed to the plate body 401 and the trapezoidal block 405; the length and width of the second right-angle notch 403 are adapted to the first block 306; an installation port 407 is provided at one end of the plate body 401 inserted into the first slot 303; the shape of the installation port 407 is adapted to the second block 308.

[0067] By adopting the above technical solution, during installation, after the I-beam 301 is erected, one end of the trapezoidal block 405 installed on the plate body 401 is facing the I-beam 301 and inserted into the second slot 304. After the inclined surface of the trapezoidal block 405 contacts the first stopper 306, the movable rod 404 contracts, so that the trapezoidal block 405 is inserted into the trapezoidal slot 307. After being inserted, the first stopper 306 below the plate body 401 provides support for the plate body 401, and one side of the trapezoidal block 405 above the plate body 401 contacts the first stopper 306. The first stopper 306 at this location can prevent the plate body 401 from rotating, thereby preventing the plate body 401 from detaching from the I-beam 301, and then subsequent operations can be performed.

[0068] Embodiment 2:

[0069] See also Figure 8-Figure 9 On the basis of Example 1, an "L"-shaped long groove 408 is further opened on the plate body 401, and a pressure rod 409 is movably installed in the long groove 408.

The thickness of the bottom surface of the plate body 401 is less than the thickness of the top surface.

[0070] By adopting the above technical solution, the plate body 401 is easy to disassemble. During disassembly, one of the I-beams 301 is rotated to separate it from the plate body 401, and then the pressure rod 409 is pressed to separate the plate body 401 from the other I-beam 301, thereby facilitating disassembly.
