Description

Technical Field

[0001] This utility model belongs to the field of sound barrier technology, specifically relating to a sound barrier that facilitates the replacement of sound-absorbing panels, sound-insulating panels, and laminated glass. Background Technology

[0002] In existing sound barrier structures widely used along roads and rail transit lines, sound insulation panels (or sound-absorbing panels) and laminated glass are the core noise reduction components. The installation of these panels generally adopts a rigid clamping method that fixes them between steel columns on both sides, that is, the edges of the panels are firmly locked to the columns by fasteners or slots, forming a strong constraint state on both sides. While this structure ensures initial installation stability, the disassembly process becomes extremely cumbersome during long-term use when individual laminated glass panels break due to external impact or sound insulation panels need replacement due to aging, dirt, or physical damage. Because the steel columns in the row are fixed in position and the spacing is not adjustable, maintenance personnel must first disconnect all connections between the damaged panels and the corresponding columns. Furthermore, in densely arranged sound barrier units, operating space is extremely limited, often requiring the loosening or removal of adjacent undamaged panels to create operating space. This significantly increases maintenance workload and time costs, necessitating multiple personnel and even the use of large equipment, thus significantly increasing maintenance expenses. In addition, traditional rigid clamping methods easily cause secondary damage to the frame or surrounding structure during disassembly, further increasing the complexity and cost of maintenance. Therefore, this invention proposes a sound barrier that facilitates the replacement of sound-absorbing panels, sound insulation panels, and laminated glass, addressing the aforementioned technical problems. Utility Model Content

[0003] The purpose of this invention is to provide a sound barrier that facilitates the replacement of sound-absorbing panels, sound-insulating panels, and laminated glass, thereby solving the aforementioned technical problems.

[0004] The specific technical solution adopted by this utility model is as follows:

[0005] This utility model provides a sound barrier that facilitates the replacement of sound-absorbing panels, sound insulation panels, and laminated glass. It includes two steel columns and multiple pushing mechanisms installed in one set of steel columns. A laminated glass body and a sound insulation panel body are installed between the two steel columns. Multiple sets of elastic clamping mechanisms for clamping the frame and the forming frame are installed in the other steel column. The frame is installed on the outer periphery of the laminated glass body, and the forming frame is installed on the outer periphery of the sound insulation panel body.

[0006] The jacking mechanism is provided with fixed angle steel on the inner side opposite to the steel column.

[0007] Preferably, the pushing mechanism includes an inner frame and two rotating shafts. The inner frame is fitted inside one of the steel columns and is clamped to the inner side of the steel column by means of a fixed angle steel. The two rotating shafts are respectively fitted into two sleeve holes, which are respectively opened on the upper and lower sides of one of the side plates of the inner frame.

[0008] Preferably, the inner frame is provided with two first swing arms. The first swing arms are fixed on one side of the rotating shaft. The right vertical surface of the first swing arms is fixed with a pushing shaft for pushing the frame or the forming frame, and the pushing shaft abuts against the side of the frame or the forming frame.

[0009] Preferably, the outer side of the inner frame is provided with a second swing arm, and the second swing arm is fixedly mounted on the other side of the rotating shaft in parallel with the first swing arm. The second swing arm is fitted with a pin through a through hole on its right side.

[0010] Preferably, a spiral post and a tensioning wire are provided between the two second swing arms. The tensioning wire is threaded into the internal thread of the spiral post. The opposite sides of the tensioning wire and the spiral post are respectively connected to two U-shaped buckles. The U-shaped buckles are sleeved on the pin and locked on both sides of the second swing arm.

[0011] Preferably, a fixing ring is fixedly provided on the lower side of the tension wire, and the fixing ring is located inside the U-shaped buckle on the lower side. The lower side of the tension wire passes through the U-shaped buckle on the lower side and is restricted from moving upward by the fixing ring. The upper side of the spiral hole post is welded and fixed to the bottom surface of the upper U-shaped buckle. Two symmetrical torsion strips are fixedly provided on the outer periphery of the tension wire.

[0012] Preferably, the elastic clamping mechanism includes two sets of first retaining rings and two sets of second retaining rings. The two sets of first retaining rings are symmetrically and vertically fixed together, and have large retaining corner portions on their inner sides for engaging the edges of the frame or the corners of the molded frame. The two sets of second retaining rings are symmetrically and vertically fixed together, and have small retaining corner portions on their inner sides for engaging the edges of the frame or the corners of the molded frame. A connecting strip is fixed between the first retaining rings and the second retaining rings. Both the first retaining rings and the second retaining rings are set as three-quarters open circles, and the inner diameter of the first retaining ring is set as three times the inner diameter of the second retaining ring.

[0013] The beneficial effects are:

[0014] 1. This utility model utilizes a pushing mechanism and an elastic clamping mechanism on both sides of the frame or molded frame. By adjusting the tension wire on the pushing mechanism, the frame or molded frame can be displaced, disengaging from the slot on the steel column. This facilitates the removal and replacement of the frame for installing the laminated glass or the molded frame for installing the sound insulation panel. Subsequently, by reversing the operation of the tension wire on the pushing mechanism, the pushing shaft pushes the frame or molded frame back to its original position, causing the elastic clamping mechanism to penetrate deeper into the steel column, forming a locking and limiting mechanism on both sides. This operation process enables convenient replacement of laminated glass or sound insulation panels, significantly optimizing disassembly and replacement steps and improving replacement efficiency.

[0015] 2. This utility model, through the coordinated operation of the pushing mechanism and the elastic clamping mechanism, can effectively adapt to the existing steel column structure and facilitate the replacement of standard-sized laminated glass or sound insulation panels, thereby improving the compatibility and practicality of the product.

[0022] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0023] like Figure 1-4As shown, a sound barrier that facilitates the replacement of sound-absorbing panels, sound-insulating panels, and laminated glass includes two steel columns 1 and multiple pushing mechanisms 2 installed in one set of steel columns 1. A laminated glass body 3 and a sound-insulating panel body 4 are installed between the two steel columns 1. Multiple sets of elastic clamping mechanisms 5 are installed in the other steel column 1 for clamping the frame 31 and the forming frame 41. The frame 31 is installed on the outer periphery of the laminated glass body 3, and the forming frame 41 is installed on the outer periphery of the sound-insulating panel body 4.

[0024] The jacking mechanism 2 and the inner side of the steel column 1 are provided with fixed angle steel 6. The steel column 1 is H-shaped.

[0025] As an optional implementation, the pushing mechanism 2 includes an inner frame 21 and two rotating shafts 22. The inner frame 21 is fitted inside one of the steel columns 1 and is clamped to the inner side of the steel column 1 by the fixing angle steel 6. The two rotating shafts 22 are respectively fitted into two sleeve holes 21a, and the two sleeve holes 21a are respectively opened on the upper and lower sides of one of the side plates of the inner frame 21. This facilitates the fixing operation of the pushing mechanism 2 installed in the steel column 1.

[0026] See attached document Figure 2 and attached Figure 3 The inner frame 21 is provided with two first swing arms 23. The first swing arms 23 are fixed on one side of the rotating shaft 22. The right vertical surface of the first swing arm 23 is fixed with a push shaft 23a for pushing the frame 31 or the forming frame 41. The push shaft 23a abuts against the side of the frame 31 or the forming frame 41, thereby using the two symmetrical push shafts 23a to form a synchronous pushing effect on the frame 31 or the forming frame 41, and to form a pushing and tightening effect on the frame 31 or the forming frame 41.

[0027] Furthermore, a second swing arm 24 is provided on the outer side of the inner frame 21, and the second swing arm 24 is fixedly mounted on the other side of the rotating shaft 22 in parallel with the first swing arm 23. The second swing arm 24 is fitted with a pin 24a through a through hole on its right side, so that when the rotating shaft 22 rotates in the sleeve hole 21a, it drives the first swing arm 23 and the second swing arm 24 to rotate in opposite directions synchronously, thereby coping with subsequent adjustment linkage.

[0028] Furthermore, a spiral post 26 and a tensioning wire 27 are provided between the two second swing arms 24. The tensioning wire 27 is threadedly engaged with the internal thread of the spiral post 26. The opposite sides of the tensioning wire 27 and the spiral post 26 are respectively connected to two U-shaped buckles 25. The U-shaped buckles 25 are sleeved on the pin 24a and locked on both sides of the second swing arm 24, thereby forming a movable connection between the U-shaped buckles 25 and the second swing arm 24, which facilitates the synchronous rotation when the second swing arm 24 rotates later.

[0029] Furthermore, a fixing ring is fixedly provided on the lower side of the tensioning wire 27, and the fixing ring is located inside the lower U-shaped buckle 25. The lower side of the tensioning wire 27 passes through the lower U-shaped buckle 25 and is restricted from moving upward by the fixing ring. The upper side of the spiral hole post 26 is welded and fixed to the bottom surface of the upper U-shaped buckle 25. Two symmetrical torsion bars 27a are fixedly provided on the outer periphery of the tensioning wire 27, so as to facilitate the rotation and adjustment of the tensioning wire 27. The tensioning wire 27 can drive the two U-shaped buckles 25 to move closer to each other, thereby driving the second swing arm 24 to move closer to each other.

[0030] See attached document Figure 2 and attached Figure 4 The elastic clamping mechanism 5 includes two sets of first clamping rings 51 and two sets of second clamping rings 52. The two sets of first clamping rings 51 are symmetrically and vertically fixed together, and have large clamping corners on their inner sides for clamping the edges of the frame 31 or the forming frame 41. The two sets of second clamping rings 52 are symmetrically and vertically fixed together, and have small clamping corners on their inner sides for clamping the edges of the frame 31 or the forming frame 41. A connecting strip 53 is fixed between the first clamping rings 51 and the second clamping rings 52. Both the first clamping rings 51 and the second clamping rings 52 are set as three-quarters open circles, and the inner diameter of the first clamping ring 51 is set as three times the inner diameter of the second clamping ring 52. This facilitates the handling of the frame 31 or the forming frame 41 being restricted by the pushing mechanism 2, so that the elastic clamping mechanism 5 ensures that the frame 31 and the forming frame 41 are on the same straight line, ensuring a flat effect after installation.

[0031] Using the above structure, firstly, by twisting and replacing the torsion bar 27a on the outer periphery of the tension wire 27 in the push mechanism 2 at the corresponding position of the plate, the tension wire 27 is rotated out of the spiral hole column 26, causing the two U-shaped buckles 25 to move away from each other, thereby driving the two second swing arms 24 to swing outward with the pivot 22 as the fulcrum; since the second swing arm 24 is coaxially fixed with the first swing arm 23 and rotates in opposite directions, the first swing arm 23 rotates inward accordingly, causing the push shaft 23a at its end to retract inward to the steel column 1, releasing the frame 31. Or the pushing force of the molding frame 41; at this time, the frame 31 or the molding frame 41 still maintains part of the clamping force under the elastic constraint of the elastic clamping mechanism 5 (the large clamping corner of the first clamping ring 51 and the small clamping corner of the second clamping ring 52), but the retraction of the pushing shaft 23a gives it room to move, and the maintenance personnel can take advantage of this to horizontally pull the laminated glass together with its frame 31 or the sound insulation board body 4 together with its molding frame 41 out of the slot of the steel column 1 to complete the disassembly; when installing new panels, the frame 31 of the new laminated glass or the new sound insulation board The forming frame 41 of the main body 4 is aligned with the mounting position between the two steel columns 1, and the first retaining ring 51 and the second retaining ring 52 of the elastic clamping mechanism 5 correspond to the inner side of the steel column 1; then, the torsion bar 27a of the push mechanism 2 at this position is rotated in the opposite direction, so that the tension wire 27 is screwed into the spiral hole column 26, pulling the two U-shaped buckles 25 closer to each other, driving the second swing arm 24 to swing inward, and then synchronously driving the first swing arm 23 to rotate outward through the rotating shaft 22, and the push shaft 23a on the first swing arm 23 extends outward accordingly. The frame 31 or the molded frame 41 is pressed firmly against its side and forcefully pushed towards the opposite steel column 1. This pushing force allows the frame 31 or the molded frame 41 to overcome the initial constraint of the elastic clamping mechanism 5 and further precisely position itself. It also forces the elastic clamping mechanism 5 (especially the first retaining ring 51 and the second retaining ring 52 supported by the connecting strip 53) to be more deeply engaged in the preset position inside the steel column 1. Finally, the main pushing force provided by the pushing mechanism 2 and the double-sided clamping limit formed by the elastic clamping mechanism 5 work together to achieve a stable installation of the plate. This process does not require loosening adjacent units or disassembling structural components, and a single person can quickly complete the replacement using simple tools.
