Description

Technical Field

[0001] The utility model relates to the field of anti-loosening structures, in particular to an anti-loosening structure for a sound barrier screen body. Background Art

[0002] With the development of transportation networks, the number of elevated bridges has increased exponentially, from densely populated cities to sparsely populated suburbs and rural areas. The resulting noise from vehicles and rail transit has significantly impacted people living along these routes. For example, noise from car horns, rail wheel and rail noise, and airborne noise not only disrupt people's lives and sleep but also, over time, damage the auditory system. On rail transit lines, installing sound barriers on both sides of bridge beams is an effective way to reduce noise. These barriers primarily utilize vertical, fully enclosed, or semi-enclosed structures. These barriers consist of two H-shaped steel columns with a sound-absorbing screen inserted between them. The screen snaps into the slots formed by the web and flanges of the H-shaped steel, creating a noise-reducing shield.

[0003] In the existing technology, such as the "Anti-loosening and Anti-falling Structure of a Sound Barrier Screen Body" with the Chinese Authorization Announcement No. CN116145586B, it includes a plurality of mounting columns, the mounting columns are H-shaped steel; a plurality of screen bodies, the two ends of the screen bodies are clamped in the slots formed by the web and wing plates of the H-shaped steel, and the upper and lower ends of the screen bodies are provided with mutually matching male and female structures; a plurality of support members, the support members are arranged in the slots and abut the screen bodies, the support members are arranged at the joints of the two screen bodies spliced together, and a clamping structure is provided between the support members and the screen bodies. By splicing the male and female structures, a certain screen body can be prevented from falling out relative to the entire sound barrier, and the clamping structure is provided between the support members and the screen body, which can achieve "bottoming" insurance for the screen body and prevent the screen body from falling. The coordination of the male and female structures, the clamping structure and the screen body on the mounting columns can effectively solve the hidden danger of the screen body falling off.

[0004] In the existing technology, due to construction errors, the overlap length between the screen body and the H-shaped steel column flange plate is insufficient. Under the influence of train vibration and back-and-forth positive and negative wind pressure, the column bolts become loose, the buffer rubber strips age and deteriorate, and the elasticity bulges, causing the screen body to loosen and the overlap gap with the column to further increase, eventually causing the sound barrier screen body to loosen and fall into the track area or the municipal road below, affecting operational safety.

[0005] Therefore, it is necessary to provide a sound barrier screen anti-loosening structure to solve the above technical problems. Utility Model Content

[0007] In order to solve the above technical problems, the utility model provides a sound barrier screen anti-loosening structure, including a column, a transparent partition window is fixedly sleeved inside the column, a honeycomb panel is fixedly sleeved on the side of the transparent partition window, a positioning groove is opened on the side of the transparent partition window, a clamping sleeve is fixedly sleeved inside the positioning groove, a limiting mechanism is arranged inside the column, an anti-slip mechanism is arranged inside the column, a shock-absorbing pad is fixedly connected to the bottom of the inner cavity of the column, and a closing mechanism is arranged on the top of the column.

[0012] Preferably, the limiting mechanism includes a limiting sleeve, the limiting sleeve is fixedly connected to the front side of the transparent partition window, and the internal thread of the limiting sleeve is connected with a bolt.

[0013] Preferably, the shock-absorbing pad is located directly below the transparent partition window, and the shock-absorbing pad is made of rubber material.

[0014] Preferably, the closing mechanism includes a top cover, which is movably sleeved on the top of the column, and a clamping block is fixedly sleeved on the bottom of the top cover.

[0027] The column 1 is compatible with the transparent partition window 2, and the material of the column 1 is aluminum alloy; by setting the column 1, when the sound barrier screen is installed and fixed, the length of the column 1 is cut to achieve the limiting and fixing effect of the transparent partition windows 2 of different heights, thereby facilitating the limiting and fixing of transparent partition windows 2 of different specifications, and thus facilitating the installation and fixation of the sound barrier screen.

[0028] The transparent partition window 2 is made of organic glass, and the front shape of the transparent partition window 2 is conical; by setting the transparent partition window 2, when the honeycomb panel 3 is installed and fixed, the transparent partition window 2 can limit and fix the honeycomb panel 3 inside the column 1, thereby avoiding the problem that the honeycomb panel 3 is relatively fragile, resulting in poor uniform force when the honeycomb panel 3 is squeezed and fixed, resulting in poor fixing strength of the honeycomb panel 3.

[0030] The limiting mechanism 6 includes a limiting sleeve 61, which is fixedly connected to the front of the transparent partition window 2, and the internal thread of the limiting sleeve 61 is sleeved with a bolt 62; by setting the limiting mechanism 6, when the transparent partition window 2 is installed and fixed, the transparent partition window 2 is sleeved inside the column 1, and the bolt 62 is rotated at this time so that the bolt 62 can clamp and limit the transparent partition window 2 through the limiting sleeve 61, so that the transparent partition window 2 can be stably limited in the middle of the inner cavity of the column 1, so that the water flow inside the column 1 can flow quickly to the outside of the column 1, thereby avoiding the problem of water flow being retained inside the column 1 and causing corrosion inside the column 1.

[0031] The shock-absorbing pad 8 is located directly below the transparent partition window 2, and the material of the shock-absorbing pad 8 is rubber material; by setting the shock-absorbing pad 8, when the shock-absorbing pad 8 is being installed and fixed, the shock-absorbing pad 8 can support and limit the transparent partition window 2, thereby avoiding the problem of the transparent partition window 2 colliding with the bottom of the inner cavity of the column 1 when shaking, thereby improving the shock-absorbing effect of the sound barrier screen during installation and use.

[0032] The closing mechanism 9 includes a top cover 91, which is movably sleeved on the top of the column 1, and a clamping block 92 is fixedly sleeved on the bottom of the top cover 91; by setting the closing mechanism 9, when the sound barrier screen is installed and fixed, the clamping block 92 is sleeved on the top of the column 1, so that the clamping block 92 can clamp the top cover 91 on the top of the column 1, thereby achieving the sealing effect of the column 1, avoiding the problem of a large amount of dust and rainwater entering the interior of the column 1, causing the interior of the column 1 to be dirty and difficult to clean, thereby improving the cleanliness of the interior of the sound barrier screen.

[0033] The material of the honeycomb panel 3 is metal aluminum material, and the honeycomb panel 3 is compatible with the transparent partition window 2; by setting the honeycomb panel 3, when the sound barrier screen is used outdoors, the honeycomb panel 3 can greatly improve the anti-oxidation corrosion resistance, thereby avoiding the problem of corrosion of the sound barrier screen when it is eroded by rain for a long time, thereby improving the service life of the sound barrier screen.

[0034] The working principle of the anti-loosening structure of the sound barrier provided by the utility model is as follows:

[0035] The first step: First, when installing and fixing the screen, the transparent partition window 2 is sleeved on the inside of the column 1. At this time, the sleeve 5 is sleeved on the outside of the positioning groove 4 and one end of the sleeve 5 is fixed and welded to the front of the column 1, so that the sleeve 5 can limit the position of the transparent partition window 2 through the positioning groove 4, thereby avoiding the transparent partition window 2 being blown by the airflow of the vehicle for a long time, causing the transparent partition window 2 to gradually loosen and then fall off from the inside of the column 1, thereby improving the fixing effect of the sound barrier screen, that is, improving the safety of the sound barrier screen during use. When installing and fixing the sound barrier screen, the length of the column 1 is cut to achieve the limiting and fixing effect of transparent partition windows 2 of different height values, thereby bringing convenience to the limiting and fixing of transparent partition windows 2 of different specifications, and thus bringing convenience to the installation and fixation of the sound barrier screen. When installing and fixing the honeycomb panel 3, the transparent partition window 2 is able to limit and fix the honeycomb panel 3 on the inside of the column 1, thereby avoiding The problem of the honeycomb panel 3 being fragile and resulting in poor uniform force when the honeycomb panel 3 is squeezed and fixed, and the poor fixing strength of the honeycomb panel 3, is avoided. When the transparent partition window 2 is installed and used, the No. 1 anti-skid pad 71 and the No. 2 anti-skid pad 72 can greatly improve the friction between the transparent partition window 2 and the inner wall of the column 1, thereby avoiding the transparent partition window 2 from shaking frequently when blown by the airflow for a long time, and then frequently rubbing against the inner wall of the column 1, thereby improving the service life of the transparent partition window 2. When the transparent partition window 2 is installed and fixed, the transparent partition window 2 is sleeved on the inside of the column 1. At this time, the bolt 62 is rotated so that the bolt 62 can clamp and limit the transparent partition window 2 through the limiting sleeve 61, so that the transparent partition window 2 can be stably limited in the middle of the inner cavity of the column 1, so that the water flow inside the column 1 can quickly flow to the outside of the column 1, thereby avoiding the problem of water flow being retained in the column 1, causing corrosion inside the column 1;

[0036] Step 2: When the transparent partition window 2 is being installed and fixed, the shock-absorbing pad 8 is able to support and limit the transparent partition window 2, so as to avoid the problem of the transparent partition window 2 colliding with the bottom of the inner cavity of the column 1 when shaking, thereby improving the shock-absorbing effect of the sound barrier screen during installation and use. When the sound barrier screen is being installed and fixed, the block 92 is sleeved on the top of the column 1, so that the block 92 can block and limit the top cover 91 on the top of the column 1, thereby achieving the sealing effect of the column 1, so as to avoid a large amount of dust and rainwater entering the interior of the column 1, causing the interior of the column 1 to be dirty and difficult to clean, thereby improving the cleanliness of the interior of the sound barrier screen. When the sound barrier screen is used outdoors, the honeycomb panel 3 is able to greatly improve the anti-oxidation and corrosion resistance, so as to avoid the problem of corrosion of the sound barrier screen when it is eroded by rain for a long time, thereby improving the service life of the sound barrier screen.

[0037] Compared with the related art, the anti-loosening structure of the sound barrier provided by the utility model has the following beneficial effects:

[0038] By setting the clamping sleeve 5, when the screen body is installed and fixed, the transparent partition window 2 is sleeved on the inside of the column 1. At this time, the clamping sleeve 5 is sleeved on the outside of the positioning groove 4 and one end of the clamping sleeve 5 is fixed and welded to the front of the column 1, so that the clamping sleeve 5 can limit the position of the transparent partition window 2 through the positioning groove 4, thereby avoiding the transparent partition window 2 being blown by the airflow of the vehicle for a long time, causing the transparent partition window 2 to gradually loosen and then fall off from the inside of the column 1, thereby improving the fixing effect of the sound barrier screen, that is, improving the safety of the sound barrier screen when in use.
