Description

Technical Field

[0001] The utility model relates to the technical field of noise reduction and control in the petrochemical industry, and in particular to a sound barrier added by utilizing an existing enclosure wall. Background Art

[0002] In the field of petrochemical noise reduction technology, sound barriers, as an important sound insulation and protection structure, play a vital role. With the continuous improvement of environmental protection requirements and the gradual deepening of people's understanding of noise pollution, the demand for sound barriers is also growing.

[0003] Traditional noise barriers can meet general noise reduction needs in many situations. However, the situation is more complex in oil and gas field stations. For one thing, the initial design of existing walls often fails to incorporate the foundational design of noise barriers, which creates numerous challenges when noise reduction measures are needed later. Furthermore, oil and gas field stations often have unique environments, with noise of varying frequencies and intensities generated by the operation of various equipment, placing higher demands on the effectiveness and stability of noise reduction measures.

[0004] Currently, there's a lack of suitable solutions for adding sound barriers to existing walls. This not only hinders noise reduction efforts but also hinders timely and effective solutions to noise issues at oil and gas field stations. Traditional methods, such as connecting steel columns to foundations or embedding steel plates and bolts, are difficult to implement on existing walls due to the lack of reliable connection methods. This can lead to instability in the sound barriers, compromising their sound insulation effectiveness. Furthermore, inappropriate connection methods can damage existing walls, posing safety risks.

[0005] In summary, in order to solve the problem of adding sound barrier structures to existing walls, an innovative solution is urgently needed to meet the noise reduction needs of oil and gas field stations. Utility Model Content

[0007] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0008] A sound barrier added using an existing wall, characterized by comprising a column end connector, a structural column extension device, and a sound barrier steel column;

[0009] The column end connector includes a bottom plate, the bottom plate is connected to a second top plate via a stiffening plate, and the second top plate is connected to the first top plate;

[0010] The structural column extension device includes a first extension plate and a second extension plate, wherein the first extension plate and the second extension plate are fixedly connected via a surrounding plate;

[0011] The column end connecting piece is connected to the top of the structural column extension device through the bottom plate, and the column end connecting piece is fixedly connected to the bottom of the sound barrier steel column through the first top plate. The top of the structural column extension device is connected to the bottom plate of the column end connecting piece, and the other end is fixed to the wall through the first extension plate and the second extension plate.

[0012] Furthermore, the column end connecting piece is a bilaterally symmetrical structure.

[0013] Furthermore, the column end connector further includes an SMA (Shape Memory Alloy) arc plate. The upper portion of the SMA arc plate is fixedly connected to the bottom portion of the second extension plate, and the lower portion of the SMA arc plate is fixedly connected to the top portion of the base plate.

[0014] Furthermore, the column end connecting member also includes an upper friction plate and a lower friction plate; the lower friction plate includes two parallel and separated friction plates, and the bottoms of the lower friction plates are fixed to the top of the bottom plate; the top of the upper friction plate is fixed to the bottom of the second top plate, and the bottom end of the upper friction plate extends into the gap of the lower friction plate, and the overlapping parts of the upper friction plate and the lower friction plate are connected by bolts.

[0015] Furthermore, the upper friction plate and the lower friction plate are fixed by bolt fasteners, and the diameter of the screw is smaller than the diameter of the bolt hole.

[0016] Furthermore, the column end connecting member also includes a horizontal corrugated plate, and the horizontal corrugated plate is located between the upper friction plate and the stiffening plate and between the lower friction plate and the stiffening plate.

[0017] Furthermore, closing plates are placed at both ends of the cavity enclosed by the upper friction plate, stiffening plate, horizontal corrugated plate, and second top plate; and closing plates are placed at both ends of the cavity enclosed by the lower friction plate, stiffening plate, horizontal corrugated plate, and bottom plate. The closed chamber formed by the upper friction plate, stiffening plate, horizontal corrugated plate, second top plate, and closing plates, and the closed chamber formed by the lower friction plate, stiffening plate, horizontal corrugated plate, bottom plate, and closing plates are filled with metal particles.

[0018] Furthermore, the sound barrier steel columns are made of steel sections.

[0019] Furthermore, the enclosure plate, the first extension plate and the second extension plate form a cavity, and the cavity is filled with concrete.

[0020] Furthermore, the first extension plate and the second extension plate are connected with through bolts that pass through the wall.

[0021] Compared with the prior art, the present invention has the following beneficial technical effects:

[0022] The present invention provides a sound barrier that is added to an existing wall, comprising a column end connector, a structural column extension device, and a sound barrier steel column. The sound barrier steel column is connected to the structural column extension device via the column end connector, and the structural column extension device is fastened to the wall, thereby achieving a stable connection while having excellent energy dissipation performance.

The friction plate is fixed by a bolt fastener, the screw diameter is smaller than the bolt hole diameter, and the friction force can be adjusted by adjusting the bolt preload.

[0023] Furthermore, if the column ends of the existing sound barrier on the wall are displaced during strong winds, the upper and lower connecting plates will drive the SMA curved plates to deform. The SMA material is a shape memory alloy and can actively restore to its original shape after deformation, driving the structure to achieve recoverable function.

[0024] Furthermore, the column end connector is provided with a horizontal corrugated plate, which can deform in the horizontal direction and dissipate energy to offset the energy accumulated in the horizontal direction; at the same time, the closed cavity formed by the horizontal corrugated plate and the closed plate is filled with metal particles, and the collision and friction of the metal particles against the inner wall of the cavity can further enhance the energy dissipation effect of the structure.

[0025] Furthermore, the column end connectors are prefabricated with the upper steel columns and lower wall extensions, allowing them to be prefabricated in the factory and installed on site. If a node or sound barrier structure is damaged, it will not damage the existing wall and can be quickly replaced.

[0026] In summary, a sound barrier constructed using an existing wall ensures a stable connection to the existing wall. Furthermore, in high wind conditions, this construction method ensures multiple energy dissipation points at the column ends, allowing for rapid recovery and protecting the column end nodes. Furthermore, the column end connectors achieve a prefabricated connection with the upper steel column and lower wall extension, significantly improving construction efficiency and enabling component replacement. This method offers significant advantages and broad application potential. BRIEF DESCRIPTION OF THE DRAWINGS
