[0002] The sound insulation screen on both sides of the road is an acoustic barrier installed on both sides of the road for reducing the influence of traffic noise on sensitive areas such as residential areas, schools and hospitals. The conventional sound insulation screen generally comprises a plurality of steel columns arranged longitudinally along the road and a sound insulation screen plate arranged between two steel columns. The sound insulation screen plate can be a metal sound insulation screen plate, a transparent sound insulation screen plate or a combination of the two. The bottom of the steel column is provided with a bottom plate, which is generally fixed to the concrete crash barrier on the side of the road by bolts. However, the existing steel column connection structure is not stable enough. Under extreme weather conditions such as strong winds and typhoons, the bolted connection part is prone to looseness or even breakage due to long-term vibration, lateral wind pressure and road surface resonance caused by vehicle driving, which in turn causes the steel column and the sound barrier to tilt or collapse, directly threatening the safety of road traffic and the safety of pedestrians' life and property.

[0027] Reference Figures 1-4 The present application embodiment shows a sound insulation screen with strong wind load capacity, comprising a steel column 1 and a sound insulation screen plate 2, the steel column 1 comprises a mounting bottom plate 11, the top of the mounting bottom plate 11 is provided with an upper column body 12 for connecting the sound insulation screen plate 2, and the bottom of the mounting bottom plate 11 is provided with a lower column body 13 for inserting a concrete crash barrier 100.

[0028] Among them, the connection structure of the upper column body 12 and the sound insulation screen plate 2 can refer to the prior art; the present embodiment increases the lower column body 13 at the bottom of the bottom plate, like Figure 2As shown, the top of the concrete crash barrier 100 is provided with a socket 110 for inserting the lower column body 13, so that the lower column body 13 can be inserted into the concrete crash barrier 100, so that the bolt provided in the first connecting hole 111 can mainly bear the vertical load, and the transverse wind pressure is mainly borne by the lower column body 13; on the one hand, even if the bolt of the first connecting hole 111 completely fails, the embedded action of the lower column body 13 and the concrete can still maintain the steel column 1 upright, avoiding the chain collapse accident; on the other hand, the fatigue damage of the bolt of the first connecting hole 111 can be reduced, and the risk of loosening or breaking of the bolt in the first connecting hole 111 can be reduced. In this way, the soundproof screen in the embodiment effectively improves the wind resistance stability and safety redundancy.

[0029] Among them, regarding the connection of the bottom plate and the concrete crash barrier 100, a mounting hole (not shown) can be formed at the top of the concrete crash barrier 100, and then an expansion bolt is passed through the first connecting hole 111 and is screwed into the mounting hole of the concrete crash barrier 100, so as to fix the bottom plate at the top of the concrete crash barrier 100;

[0030] Alternatively, a pre-buried bolt can be provided on the concrete crash barrier 100, the position of the pre-buried bolt corresponds to the position of the first connecting hole 111 on the bottom plate, and when the steel column 1 is installed, the lower column body 13 is inserted into the socket 110 on the concrete crash barrier 100, and the pre-buried bolt on the concrete crash barrier 100 is passed through the first connecting hole 111 on the bottom plate, and then locked with a nut, so as to fix the bottom plate.

[0031] In some embodiments, as shown in the drawings, Figures 1-4 As shown, the coupling beam 3 is further provided, the coupling beam 3 comprises an integrally connected top plate 31 and side plate 32, the coupling beam 3 is arranged between two steel columns 1 connected in series, the top plate 31 is arranged above the concrete crash barrier 100, and the two ends of the top plate 31 are connected to the mounting bottom plate 11 on the two steel columns 1 respectively; the side plate 32 is located on the side of the concrete crash barrier 100.

[0032] In the embodiment, the coupling beam 3 is added, the adjacent steel columns 1 are connected through the coupling beam 3, so that the multiple steel columns 1 form a whole and cooperate, through the transverse connection of the added coupling beam 3, the load can be dispersed, the stress of a single steel column 1 is reduced, and the overall stability and cooperative wind resistance capacity of the soundproof screen are significantly improved.

[0033] In addition, the side plate 32 on the coupling beam 3 abuts against the side of the concrete crash barrier 100, forming a shear key effect, which can effectively resist the torque caused by strong wind load (such as the rotation tendency caused by transverse vortex), avoiding the torsional instability of the steel column 1 and preventing the lower column body 13 from breaking.

[0034] The above scheme is specifically, for easy installation, as shown in the drawings, Figure 4As shown, two ends of the top plate 31 are respectively provided with second connecting holes 311, which are bolted with the first connecting holes 111 on the mounting bottom plate 11.

[0035] In addition, in order to avoid the transmission of vibration, a rubber pad (not shown) can be arranged between the top plate 31 and the mounting bottom plate 11. The rubber pad is used to reduce the transmission of vibration.

[0036] In addition, in order to adapt to the installation error, such as Figure 4 As shown, the second connecting holes 311 are strip-shaped holes, and the length directions of the two second connecting holes 311 on the top plate 31 are perpendicular to each other. In this way, even if there is a certain error in the installation position of the steel column 1, the installation position of the coupling beam 3 can be fine-tuned, so that the first connecting holes 111 and the second connecting holes 311 can correspond to each other to allow the bolts to pass through.

[0037] In the above scheme, specifically, the upper column body 12 is an H-shaped steel, the lower column body 13 is a square steel pipe or a circular steel pipe, and the upper column body 12, the mounting bottom plate 11 and the lower column body 13 are welded. In this way, the overall structural strength of the steel column 1 is relatively high.

[0038] Preferably, as shown in Figure 3 and Figure 4 As shown, support rib plates 14 are arranged between the inner and outer sides of the upper column body 12 and the mounting bottom plate 11. The inner side of the upper column body 12 refers to the side close to the lane, and the outer side of the upper column body 12 refers to the side away from the lane; by increasing the support rib plates 14, the wind load resistance of the connection between the upper column body 12 and the bottom plate is further improved to prevent fracture.

[0039] Conventionally, the sound insulation screen 2 is a metal sound insulation screen 2, or a transparent sound insulation screen 2, or a combination of a metal sound insulation screen 2 and a transparent sound insulation screen 2. The structure of the sound insulation screen 2 can refer to the prior art, and thus will not be described here.

[0040] In summary, the present application provides a sound insulation screen with strong wind load resistance. By inserting the lower column body 13 into the concrete crash barrier 100, the bolts arranged in the first connecting holes 111 can mainly bear the vertical load, and the lateral wind pressure is mainly borne by the lower column body 13. On the one hand, even if the bolts of the first connecting holes 111 completely fail, the embedded action of the lower column body 13 and the concrete can still maintain the steel column 1 upright to avoid chain collapse accidents. On the other hand, the fatigue damage of the bolts of the first connecting holes 111 can be reduced, and the risk of loosening or fracture of the bolts in the first connecting holes 111 can be reduced.
