Description

Technical Field

[0001] This application belongs to the technical field of noise prevention and control, and specifically relates to a sunken column foot bottom surface installation coordinated sound insulation barrier. By reducing the elevation of the installation surface of the steel structure column of the sound insulation barrier for force bearing, the bottom surface of the sound insulation barrier is made to contact more closely with the closed surface of the foundation surface, such as the top of a wall, the top of a parapet, the ground, etc., to prevent noise from escaping through the gap between the bottom of the barrier and the closed surface. Background Art

[0002] There is an existing sound insulation barrier installed on the closed surface of the foundation surface. The closed surface can be the top of a wall, the top of a parapet on the roof, the ground, etc. It is produced by professional noise reduction equipment manufacturers and is used to enclose equipment and buildings. When sound waves encounter the sound insulation barrier, reflection, transmission, and diffraction phenomena will occur. The role of the sound insulation barrier is to block, isolate, and attenuate noise to reduce noise hazards.

[0003] Problems existing in the existing barrier: The sound insulation barrier has a large area and a high height, enclosing and surrounding the noise equipment and buildings. Affected by gravity, wind load, etc., the load is large. If a steel structure is used, segmented structural columns are required to transfer the force to the sound insulation barrier foundation. In order for the structural columns to better and firmly contact the foundation, generally, steel bars and steel plates need to be embedded in the foundation. The structural columns are firmly connected to the embedded steel plates and steel bars by welding, bolts, etc. In order to level multiple structural columns, secondary grouting is required to level and unify the installation height. The above process results in the structural columns protruding from the closed surface. When installing the sound insulation barrier on the structural columns, a gap is formed between the bottom surface of the sound insulation barrier and the closed surface, such as the top of a wall, the top of a parapet on the roof, the ground, etc., resulting in noise leakage. Although the gap can be beautified by installing edge sealing parts on both sides of the gap so that the gap is not visible, the noise reduction effect of the edge sealing parts themselves is not as good as that of the sound insulation barrier itself. Therefore, the size of the gap should be minimized as much as possible. Utility Model Content

Specific embodiments

[0024] The present application will be further described below in conjunction with specific embodiments and the accompanying drawings.

[0025] Refer to Figures 1 to 5 As shown, a sunken column - foot bottom - mounted coordinated sound insulation barrier includes a foundation column 1, a foundation surface 2, a sound insulation barrier wall 3, and a fixing component. The fixing component is a barrier column foot 4 or a barrier partition column 5.

[0026] The foundation column 1 is a pre - cast reinforced concrete structure for providing support for the whole. The foundation surface 2 is located between the foundation columns 1. The foundation surface 2 is a perimeter wall, parapet wall or ground surface. That is, the foundation surface 2 can also be a reinforced concrete structure, which is cast integrally with the foundation column 1. At the same time, the foundation surface 2 can also be made of other materials (metal, wood, plastic), and can even be a stratum (soil, rock).

[0027] The upper end surface of the foundation column 1 is lower than the upper end surface of the foundation surface 2. Since the foundation column 1 is used for fixing the sound insulation barrier wall 3, the sound insulation barrier foundation column is sunk so that the sunken surface and the closed surface of the foundation surface 2 form a concave - shaped space, and the fixing component that originally needed to protrude from the closed surface is installed in the concave space.

[0028] The sound insulation barrier wall 3 is arranged above the foundation column 1 and the foundation surface 2. The sound insulation barrier wall 3 is fixed to the upper part of the foundation column 1 through the fixing component. Since the installation position of the fixing component follows the sinking of the foundation column 1, the high - position installation of the sound insulation barrier wall 3 is avoided, ensuring that the sound insulation barrier wall 3 fits the upper end surface of the foundation surface 2, thus reducing the gap.

[0029] The thickness of the foundation column 1 is greater than the thickness of the foundation surface 2, ensuring that the foundation column 1 has better strength than the foundation surface 2. The thickness of the foundation surface 2 is greater than or equal to the thickness of the sound insulation barrier wall 3, trying to ensure that the inside and / or outside of the foundation surface 2 and the sound insulation barrier wall 3 are aligned, having better aesthetics.

[0030] At the upper part of the foundation column 1, there are embedded bolts 102 passing through the upper end face. The embedded bolts 102 are J-shaped bolts. At the end of the embedded bolts 102 passing through the fixing component, there are locking nuts 103. By tightening the locking nuts 103, the fixed connection of the fixing component on the foundation column 1 is realized. Preferably, six embedded bolts 102 are arranged in two rows and three columns to ensure the reliable connection of the fixing component.

[0031] The foundation column 1 includes a secondary grouting layer 101 at the topmost layer. Due to the problem that the upper end faces are not on the same horizontal plane in the first pouring construction of the foundation column 1, in order to level multiple fixing components, it is necessary to carry out secondary grouting and leveling on the foundation column 1 to unify the installation height.

[0032] The fixing component is a barrier column foot 4 or a barrier partition column 5, both of which are used for the limit installation of the sound insulation barrier wall 3 and can be selected according to specific situations. The barrier column foot 4 only acts on the lower end of the sound insulation barrier wall 3, while the barrier partition column 5 is erected and acts on the side end of the sound insulation barrier wall 3. The limit installation of a single sound insulation barrier wall 3 is realized by using two adjacent barrier partition columns 5.

[0033] The fixing component is a barrier column foot 4. The barrier column foot 4 includes a column foot base plate 401 and a limit plate 402. The column foot base plate 401 is fixed on the foundation column 1 through the embedded bolts 102 and the locking nuts 103. The limit plate 402 is vertically welded and fixed on the column foot base plate 401. There are two front and rear limit plates 402 fixed, and the lower end of the sound insulation barrier wall 3 is fixed between the front and rear limit plates 402.

[0034] There is a column foot wing plate 403 welded between the column foot base plate 401 and the limit plate 402, and the column foot wing plate 403 strengthens the structure of the limit plate 402. The front and rear limit plates 402 form a limit groove, which restricts the front and rear positions of the sound insulation barrier wall 3. At the same time, the sound insulation barrier wall 3 is welded or fixedly connected to the limit plate 402 by screws.

[0035] The fixing component is a barrier partition column 5. The barrier partition column 5 includes a partition column base plate 501 and a partition column body 502. The partition column base plate 501 is fixed on the foundation column 1 through the embedded bolts 102 and the locking nuts 103. The partition column body 502 is vertically welded and fixed on the partition column base plate 501. The side end of the sound insulation barrier wall 3 is fixed in the placement groove of the partition column body 502, and both ends of the sound insulation barrier wall 3 are clamped in the placement groove to realize the installation and fixation.

[0036] There is a partition column wing plate 503 welded between the partition column base plate 501 and the partition column body 502, and the partition column wing plate 503 strengthens the structure of the partition column body 502. The partition column body 502 preferably has an I-shaped cross-section, and the clamping installation of the sound insulation barrier wall 3 is realized by using the placement grooves on both sides. At the same time, the sound insulation barrier wall 3 is welded or fixedly connected to the partition column body 502 by screws.

[0037] In this application, the elevation of the foundation column of the sound insulation barrier is reduced, and it is in a sunken state compared with the closed surface of the foundation, such as the top of the enclosure wall, the top of the parapet wall, the ground, etc. Bolts are embedded in the sunken foundation, and the fixing components of the sound insulation barrier are installed on the secondary grouting layer. The installed fixing components will not protrude from the plane where the foundation is located. Then, the sound insulation barrier wall is installed on the fixing components, and its bottom surface can be in close contact with the closed surface to reduce gaps.

[0038] The basic example of the present application and its various further selected examples can be freely combined to form multiple embodiments, all of which are embodiments that can be adopted and claimed in the present application. In the solution of the present application, each selected example can be arbitrarily combined with any basic example and selected example.

[0039] The above are only the preferred embodiments of the present application and are not intended to limit the present application. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present application shall be included in the protection scope of the present application.
