Description

Technical Field

[0001] The utility model relates to the field of sound barrier installation, in particular to a sound barrier installation structure for traffic engineering. Background Technique

[0002] A sound barrier is an acoustic baffle specifically designed to stand between a noise source and a sound-receiving point. The sound barrier is mainly used for sound insulation and noise reduction of highways, expressways, elevated composite roads and other noise sources;

[0003] The highway sound barrier mainly consists of two parts: a steel structure column and a sound absorption and insulation panel. The column is the main load-bearing member of the sound barrier, and it is fixed to the embedded steel plate on the road crash barrier or beside the track through bolts or welding; the sound absorption and insulation panel is the main sound insulation and absorption member, and it is clamped in the groove of the H-shaped column to form a sound barrier.

[0004] When installing the existing highway sound barrier, generally, the sound absorption and insulation panel is lifted to the uppermost opening of the column, then the sound absorption and insulation panel is inserted into the inner side of the groove of the column, and then slowly lowered to the lowest end, and then this operation is repeated. During this process, external hoisting equipment is required to frequently lift and lower the staff, which not only affects the work efficiency, but also has relatively large potential safety hazards in the frequent lifting and lowering operations. In addition, in order to install the sound absorption and insulation panel for some columns with an arc-shaped top, an installation groove is opened on the outer side of the arc-shaped top (i.e., the side far from the road surface). At this time, the staff needs to lift the sound absorption and insulation panel to the outer side of the column (i.e., the side far from the road surface), and then snap it into the column through the installation groove. The operation of lifting it to the outer side of the column has a large working intensity and great potential construction safety hazards. Based on this, a sound barrier installation structure for traffic engineering is provided. Content of the Utility Model

[0005] The purpose of the utility model is to provide a sound barrier installation structure for traffic engineering in order to solve the problems in the above background.

[0006] To achieve the above purpose, the utility model provides the following technical solution: A sound barrier installation structure for traffic engineering, including a barrier assembly composed of an I-shaped column and a sound absorption and insulation panel. A plurality of the sound absorption and insulation panels are clamped between two I-shaped columns to form a sound barrier. The sound absorption and insulation panel is composed of a first L-shaped sound insulation panel and a second L-shaped sound insulation panel with the same shape and structure. The first L-shaped sound insulation panel and the second L-shaped sound insulation panel can be horizontally inserted into the inner side of an I-shaped column first, and then vertically moved down to be spliced and combined into a sound absorption and insulation panel;

[0007] A concave card slot is formed on the inner side of the butt joint of the first L-shaped sound insulation panel and the second L-shaped sound insulation panel, and C-shaped card slots are formed on the outer side, top and bottom of the first L-shaped sound insulation panel and the second L-shaped sound insulation panel;

[0008] The first L-shaped sound insulation board and the second L-shaped sound insulation board are connected and fixed through a snap connection component, and the snap connection components are distributed inside the concave card slots and C-shaped card slots.

[0009] As a further solution of the present utility model: The snap connection component includes a bottom plate, a middle clamping column, a first side plate, a second side plate, an upper cover plate, a T-shaped through hole, and a threaded hole;

[0010] The middle clamping column is fixed in the middle of the top of the bottom plate. The first side plate and the second side plate are symmetrically fixed on both sides of the top of the bottom plate with the middle clamping column as the center. The bottom plate is clamped inside the C-shaped card slots at the bottoms of the first L-shaped sound insulation board and the second L-shaped sound insulation board. The middle clamping column is inserted inside the concave card slot. The first side plate and the second side plate are respectively clamped inside the C-shaped card slots on the outer sides of the first L-shaped sound insulation board and the second L-shaped sound insulation board;

[0011] The upper cover plate is rotatably connected to the top of the first side plate. The T-shaped through hole is opened on the upper surface of the upper cover plate and penetrates through the bottom of the upper cover plate. The threaded hole is opened at the top of the middle clamping column. The upper cover plate is rotatably clamped inside the C-shaped card slots at the tops of the first L-shaped sound insulation board and the second L-shaped sound insulation board and fits on the top of the middle clamping column. By screwing a screw through the T-shaped through hole and threadedly connecting it with the threaded hole, the connection and fixation between the upper cover plate and the middle clamping column are realized, thereby realizing the connection and fixation of the first L-shaped sound insulation board and the second L-shaped sound insulation board.

[0012] As a further solution of the present utility model: The snap connection component further includes a clamping fold and a clamping slot;

[0013] The clamping fold is fixed on one side of the upper cover plate. The clamping slot is opened at the top of the second side plate away from the first side plate. When the upper cover plate is in a horizontal state, the clamping fold is clamped inside the clamping slot for realizing the side connection limit between the first side plate and the second side plate.

[0014] As a further solution of the present utility model: A storage groove is opened on the side of the first side plate away from the second side plate. A groove for the rotation of the upper cover plate is opened at the top of the first side plate, and the storage groove communicates with the groove. The storage groove is used to provide space for the upper cover plate to rotate to be vertically downward.

[0015] As a further solution of the present utility model: The wall thicknesses of the bottom plate, the first side plate, the second side plate, and the upper cover plate match the inner wall depth of the C-shaped card slot, and the outer wall size of the middle clamping column matches the inner wall size of the rectangular slot formed by two concave card slots on the first L-shaped sound insulation board and the second L-shaped sound insulation board.

[0016] Compared with the prior art, the beneficial effects of the present utility model are:

[0017] The convenient fixation of the first L-shaped sound insulation board and the second L-shaped sound insulation board can be realized by setting the buckling component. Through the structural setting of the combined sound absorption and insulation board, the two L-shaped sound insulation boards can be installed separately, so that it is not necessary to move up to the top of the I-shaped column for installation. The overall installation efficiency is faster, effectively avoiding the construction safety hazards caused by frequent lifting and lowering, and further improving the construction safety.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0024] Please refer to Figures 1 to 4 , in the embodiment of the present invention, a sound barrier installation structure for a traffic project includes a barrier component 1 composed of an I-shaped column 101 and a sound absorption and insulation board 102. A plurality of sound absorption and insulation boards 102 are clamped between two I-shaped columns 101 to form a sound barrier. The sound absorption and insulation board 102 is composed of a first L-shaped sound insulation board 1021 and a second L-shaped sound insulation board 1022 with the same shape and structure. The first L-shaped sound insulation board 1021 and the second L-shaped sound insulation board 1022 can be horizontally inserted into the inner side of an I-shaped column 101 first and then vertically moved down to be spliced and combined into a sound absorption and insulation board 102;

[0025] An inner side of a butting joint of the first L-shaped sound insulation board 1021 and the second L-shaped sound insulation board 1022 is formed with a concave card slot 1023, and an outer side, a top and a bottom of the first L-shaped sound insulation board 1021 and the second L-shaped sound insulation board 1022 are formed with C-shaped card slots 1024;

[0026] The first L-shaped sound insulation board 1021 and the second L-shaped sound insulation board 1022 are fixedly connected through a fastening component 2, and the fastening component 2 is distributed inside the concave card slot 1023 and the C-shaped card slot 1024;

[0027] The fastening component 2 includes a bottom plate 201, a middle clamping column 202, a first side plate 203, a second side plate 204, an upper cover plate 205, a clamping folded edge 206, a T-shaped through hole 207, a threaded hole 208, and a clamping slot 209;

[0028] The middle clamping column 202 is fixed to the middle of the top of the bottom plate 201. The first side plate 203 and the second side plate 204 are symmetrically fixed to both sides of the top of the bottom plate 201 with the middle clamping column 202 as the center. The bottom plate 201 is clamped inside the C-shaped card slot 1024 at the bottom of the first L-shaped sound insulation board 1021 and the second L-shaped sound insulation board 1022. The middle clamping column 202 is inserted inside the concave card slot 1023. The first side plate 203 and the second side plate 204 are respectively clamped inside the C-shaped card slot 1024 on the outer sides of the first L-shaped sound insulation board 1021 and the second L-shaped sound insulation board 1022;

[0029] The upper cover plate 205 is rotatably connected to the top of the first side plate 203. The T-shaped through hole 207 is opened on the upper surface of the upper cover plate 205 and penetrates through the bottom of the upper cover plate 205. The threaded hole 208 is opened on the top of the middle clamping column 202. The upper cover plate 205 is rotatably clamped inside the C-shaped card slot 1024 at the top of the first L-shaped sound insulation board 1021 and the second L-shaped sound insulation board 1022 and fits against the top of the middle clamping column 202. By screwing a screw through the T-shaped through hole 207 and threadedly connecting it with the threaded hole 208, the connection and fixation between the upper cover plate 205 and the middle clamping column 202 are realized, thereby realizing the connection and fixation between the first L-shaped sound insulation board 1021 and the second L-shaped sound insulation board 1022;

[0030] The clamping folded edge 206 is fixed to one side of the upper cover plate 205. The clamping slot 209 is opened at the top of one side of the second side plate 204 away from the first side plate 203. When the upper cover plate 205 is in a horizontal state, the clamping folded edge 206 is clamped inside the clamping slot 209, so as to realize the side connection limit between the first side plate 203 and the second side plate 204.

[0031] In this embodiment, it should be noted that the I-shaped column 101 is fixed to the embedded steel plate on the road crash barrier or beside the track by bolts or welding. The slot spacing between two adjacent I-shaped columns 101 matches the overall length of the sound insulation panel 102. The installation operation steps of the sound insulation panel 102 are as follows:

[0032] First, take a set of fastening components 2 and a first L-shaped sound insulation panel 1021 (or a second L-shaped sound insulation panel 1021), and then insert the fastening components 2 and the first L-shaped sound insulation panel 1021 into each other, that is, the bottom plate 201 and the second side plate 204 are clamped inside the C-shaped card slot 1024, and the middle clamping column 202 is inserted inside the concave slot 1023 (as shown in the attachment Figure 2 shown);

[0033] After that, transfer the first L-shaped sound insulation panel 1021 and the fastening components 2 as a whole to the two I-shaped columns 101. Since the length of the first L-shaped sound insulation panel 1021 is less than the distance between the two I-shaped columns 101, the first L-shaped sound insulation panel 1021 can be placed horizontally between the two I-shaped columns 101 and inserted inside the slot of one I-shaped column 101;

[0034] Then transfer the second L-shaped sound insulation panel 1021 to the middle of the two I-shaped columns 101. At this time, only need to place the second L-shaped sound insulation panel 1021 at a position slightly higher than the first L-shaped sound insulation panel 1021, insert it horizontally inside the slot of the other I-shaped column 101, and then move the second L-shaped sound insulation panel 1021 vertically downward so that the second L-shaped sound insulation panel 1021 is clamped and flush with the first L-shaped sound insulation panel 1021. The C-shaped card slot 1024 on the first L-shaped sound insulation panel 1021 is clamped outside the bottom plate 201 and the second side plate 203, and the concave card slot 1023 on the first L-shaped sound insulation panel 1021 is clamped on the other side of the middle clamping column 202;

[0035] Then turn the upper cover plate 205 to a horizontal state. At this time, the upper cover plate 205 is clamped inside the C-shaped card slot 1024 at the top of the first L-shaped sound insulation panel 1021 and the second L-shaped sound insulation panel 1022, the clamping fold 206 is clamped inside the clamping slot 209, and the T-shaped through hole 207 is aligned with the threaded hole 208;

[0036] Finally, pass a bolt through the T-shaped through hole 207 and thread it with the threaded hole 208. In this way, the connection and fixation of the first L-shaped sound insulation panel 1021 and the second L-shaped sound insulation panel 1022 are realized, and at the same time, the installation operation of a single sound insulation panel 102 is completed. After that, repeat this operation to complete the assembly of the sound barrier;

[0037] Through the structural arrangement of the combined sound absorption and insulation panel 102, the two L-shaped sound insulation panels can be installed separately, so that it is not necessary to move them up to the top of the I-shaped column 101 for installation. The overall installation efficiency is faster, effectively avoiding the construction safety hazards caused by frequent lifting and lowering, and further improving the construction safety.

[0038] Please refer particularly to Figures 1 to 4 , a storage groove 210 is formed on the side of the first side plate 203 away from the second side plate 204, a groove for the upper cover plate 205 to rotate is formed at the top of the first side plate 203, and the storage groove 210 communicates with the groove. The storage groove 210 is used to provide space for the upper cover plate 205 to rotate to a vertically downward position.

[0039] In this embodiment: for the convenience of construction, when the buckling assembly 2 is installed, the upper cover plate 205 faces the road direction. Through the arrangement of the storage groove 210, the upper cover plate 205 can be flipped to a vertically downward state, so that the installation of the L-shaped sound insulation panel can be better carried out.

[0040] Please refer particularly to Figures 1 to 4 , the wall thicknesses of the bottom plate 201, the first side plate 203, the second side plate 204 and the upper cover plate 205 match the inner wall depth of the C-shaped card slot 1024, and the outer wall dimensions of the middle clamping column 202 match the inner wall dimensions of the rectangular slot formed by the two concave card slots 1023 on the first L-shaped sound insulation panel 1021 and the second L-shaped sound insulation panel 1022.

[0041] In this embodiment: through this structure, the two L-shaped sound insulation panels can be kept in a stable state after being spliced and assembled with each other, so that the sound absorption and insulation panel 102 will not become loose during use.

[0042] The above is only the preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent substitutions or changes, and should be covered by the protection scope of the present invention.
