Description

Technical Field

[0001] The embodiment of the utility model relates to the technical field of composite board installation structures, and in particular to a noise reduction and sound absorption composite board dry hanging structure. Background Art

[0002] With the rapid development of urban construction, smooth urban traffic and urban traffic noise pollution have become the two major issues that must be addressed for sustainable urban development. Urban traffic congestion often occurs at the intersections of urban main roads. The construction of a three-dimensional intersection with an underpass has become one of the powerful measures for cities to effectively improve traffic capacity, divert traffic, and solve traffic congestion. But at the same time, the impact of underpass noise on the environment cannot be ignored. Therefore, controlling the noise of underpass tunnels on urban roads is of great significance to achieving sustainable urban development.

[0003] In recent years, the country has advocated the development of green buildings. Perforated sound-absorbing composite panels are newly developed, the second generation of green computer room special sound-absorbing panels. The material is composed of a lightweight and high-strength perforated panel with a glass wool board attached to it, which achieves the purpose of noise reduction by sound absorption.

[0004] For example, the dry hanging structure of a stone composite panel disclosed in Chinese patent application number CN201822206837.8 has the following specific contents: including a hanging piece fixed to the back of the stone and a connecting piece fixed to the wall, the hanging piece includes a first vertical surface, a first horizontal connecting surface and a trough, one end of the first horizontal connecting surface is connected to the middle of the first vertical surface, and the other end of the first horizontal connecting surface is connected to the trough, the connecting piece includes a second vertical surface, a second horizontal connecting surface and a vertical supporting surface connected in sequence, and the vertical supporting surface extends into the trough to realize the connection between the hanging piece and the connecting piece. The hanging piece is fixed to the back of the stone, and the connecting piece is fixed to the wall. The connecting piece can be fixed to the wall or the keel by bolts. It has the following technical problems:

[0005] After the connector fixedly mounted on the wall or keel is connected to the hanging member, the connector bears the weight of the hanging member and the composite board. However, the second horizontal connection surface on the connector is prone to bending after long-term weighing, causing the installation position of the composite board to shift. Utility Model Content

[0006] To this end, an embodiment of the utility model provides a noise reduction and sound absorption composite panel dry hanging structure to solve the problem of offset of the installation position of the composite panel in the prior art.

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

[0008] A dry hanging structure of a noise reduction and sound absorption composite board comprises a second dry hanging connector installed on the left side of the noise reduction and sound absorption composite board and a first dry hanging connector used for supporting and limiting the noise reduction and sound absorption composite board in cooperation with the second dry hanging connector.

[0009] The first dry hanging connector includes a vertical plate, and a first horizontal plate and a second horizontal plate for supporting the second dry hanging connector are installed on the right side of the vertical plate.

[0010] A limit plate is installed at the upper end of the vertical plate, and a plurality of clamping blocks for locking the second dry hanging connector are installed at the lower right end of the limit plate.

[0011] The second dry hanging connector includes a U-shaped block, the upper end of which is provided with a plurality of slots for cooperating with the card block to lock the U-shaped block, and the middle part of the upper end of the U-shaped block is provided with a limiting slot 1 for facilitating left and right adjustment of the noise reduction and sound absorption composite panel.

[0012] Furthermore, a first screw is installed at the left end of the noise reduction and sound absorption composite plate, and a first washer and a first nut for locking the U-shaped block are installed at the left end of the first screw.

[0013] Furthermore, bolts are installed at the upper and lower ends of the vertical plate, and a first reinforcing rib is installed at the lower end of the first horizontal plate.

[0014] Furthermore, a second reinforcing rib is installed at the lower end of the second transverse plate, a second screw rod is installed at the middle upper end of the second transverse plate, and a limiting protrusion is installed at the right upper end of the second transverse plate.

[0015] Furthermore, a second washer and a second nut for controlling the deformation of the limiting plate are installed on the upper end of the second screw rod.

[0016] Furthermore, a limiting hole 1 for limiting the second screw rod is provided in the middle of the limiting plate.

[0017] Furthermore, a second limiting hole is provided in the middle of the U-shaped block for limiting the first screw, a second limiting groove is provided in the middle of the upper end of the U-shaped block for the limiting protrusion to slide, and a third limiting groove is provided at the upper end of the groove cavity of the second limiting groove for cooperating with the limiting protrusion to prevent the U-shaped block from falling off.

[0018] The utility model embodiment has the following advantages:

[0019] The U-shaped block is locked to the left side of the noise reduction and sound absorbing composite board by rotating the first nut, and the upper and lower ends of the U-shaped block are placed on the upper ends of the first cross plate and the second cross plate, and the limiting protrusion is synchronously inserted into the groove cavity of the limiting groove two, and the second screw is in the groove cavity of the limiting groove one. When the adjacent noise reduction and sound absorbing composite boards are adjusted to be flat, the second nut is rotated so that the second washer synchronously presses down the right end of the limiting plate, so that the blocking block and the blocking groove are engaged, thereby completing the locking of the U-shaped block, and the U-shaped block is not easy to shift. By setting the first reinforcing rib and the second reinforcing rib, the mechanical strength of the first cross plate and the second cross plate is also increased, so that the utility model can support the noise reduction and sound absorbing composite board for a long time and avoid the position shift of the U-shaped block.

[0032] See also Figure 1-Figure 5 The utility model provides a dry hanging structure of a noise reduction and sound absorption composite panel, including a dry hanging connector 200 installed on the left side of the noise reduction and sound absorption composite panel 20 and a dry hanging connector 100 used to cooperate with the dry hanging connector 200 to support and limit the noise reduction and sound absorption composite panel 20, and the left end of the dry hanging connector 100 is installed on the wall 10 through a bolt 111. When the dry hanging connector 100 is installed, a hole is opened on the wall 10, and an expansion tube is placed in it, and the bolt 111 is rotated into the expansion tube to fix the dry hanging connector 100 on the wall.

[0033] A first screw 21 is fixedly installed on the left end of the noise reduction and sound absorption composite panel 20 , and a first washer 22 and a first nut 23 are installed on the left end of the first screw 21 for locking the U-shaped block 210 , and the U-shaped block 210 is located between the noise reduction and sound absorption composite panel 20 and the first washer 22 .
