Detailed Description
The following detailed description refers to the accompanying drawings.
The invention provides a sound barrier structure and a construction method thereof. The present invention also provides a connecting member. The invention also provides a sound insulation shed.
Example 1
A sound barrier structure, as shown in fig. 1 and 2, at least comprises a frame body 1 with radian, a plurality of sound barrier plates 6 and a plurality of light-permeable hollow plates 2. The frame 1 constitutes a frame having an arc, thereby forming a frame having a top frame. The sound barrier panel 6 is a panel body capable of isolating sound and absorbing sound. The sound barrier panel 6 is, for example, a panel body filled with a sound absorbing material. The light-permeable hollow plate 2 is a plate body which allows light to pass through and has a hollow structure inside so as to be sound-proof. The light-permeable hollow plate 2 is for example a polycarbonate plate, also called solar plate.
The plate body 21 constituting the sound barrier structure is not limited to the sound barrier plate 6 and the light-permeable hollow plate 2, but may include a see-through soundproof window body 13. In the sound barrier structure, the order of the low to high settings is: an acoustic barrier panel 6, a light-permeable hollow panel 2; or as shown in fig. 8, the sound barrier panel 6, the see-through sound insulation window 13 and the light-permeable hollow panel 2 are arranged in the order from low to high. The sound barrier structure of the invention can be a semi-closed shed, the top of which has a blank area, or a fully-closed shed, i.e. the top of which also forms a ceiling. The present invention is preferably a fully enclosed shelter as shown in figures 1 and 2.
The light-permeable hollow plate 2 is arranged in the top area of the frame body 1, and can transmit light in a large area so that light rays in the shed body formed by the sound barrier structure are sufficient. Meanwhile, the light-permeable hollow plate 2 has the effects of sound insulation and rain shielding, so that the construction is prevented from being influenced by wind and rain, and the continuous operation of a construction site is realized.
For example, the sound barrier panel 6 is provided on the frame body 1 in such a manner that its first position is lower than the second position of the light-transmitting hollow panel 2. The sound barrier plate 6 is provided at a lower position, and can sufficiently absorb noise emitted from the machine on the construction floor, thereby reducing the propagation range of noise.
For example, the perspective sound insulation window 13 is arranged between the sound barrier area 4 and the light-permeable hollow plate 2, so that the light near the ground is further enhanced, the requirements of setting the light near the ground and energy consumption are reduced, and the energy-saving and environment-friendly effects are realized. The perspective sound insulation window 13 is a safety glass with a sandwich layer in the middle part and is provided with a glue clamping function, and has a sound insulation function while transmitting light. Preferably, the sound barrier region 4 has a height of preferably 3.
Preferably, as shown in fig. 2, in a region where construction noise is low, the sound barrier region 4 in the sound barrier structure may be replaced by the perspective hollow plate 2 and/or the steel wire mesh 5 instead of the sound barrier plate 6 to support the top canopy body formed by the perspective hollow plate 2 to achieve local sound insulation and rain shielding.
In the prior art, each plate body that constitutes the canopy body needs constructor to carry out accurate concatenation to make the gap less between the plate body, improve the sound insulation effect. However, since the plate bodies are connected by using the common steel columns 7, gaps between the steel columns 7 and the plates and between the plates are still large, so that noise is transmitted through the gaps, and a good sound insulation effect is not achieved. Meanwhile, a constructor needs to consume a great deal of effort and time for maintaining the non-deformation connection and accurate splicing of the plate body, so that the construction efficiency is low.
In order to improve the problems, the edge structure of the plate body and the connecting member are improved, so that even if constructors reduce the construction precision, gaps between the plate bodies are smaller and even no gaps are left, the sound insulation effect is improved, and the construction efficiency of the constructors can be improved.
Fig. 3 to 8 show different plate bodies 21 with sound barrier structures from low to high. As shown in fig. 3 to 8, the sound barrier 6 is provided near the ground, and the sound barrier 6 is provided on the pre-buried upright post. The steel column 7 is arranged upright through the upright post. In the upright region of the sound barrier structure, the steel columns 7 maintain the plate body in an upright shape and angle. When the two plates need to be slightly bent, the steel columns 7 are not used, so that the angle change of the plate body can adapt to the radian change of the frame body 1. In the present invention, the plate 21 refers to any plate constituting a sound barrier structure.
Preferably, as shown in fig. 8, when the perspective hollow plate 2 is disposed on top of the frame body 1, the diagonal bracing assembly 14 and the longitudinal bracing assembly 15 can be disposed within a rectangular frame composed of two steel columns 7 and the connection members 16, so that the frame body 1 is more stable.
Specifically, as shown in fig. 9 and 10, at least one side surface of the sound barrier panel 6 and/or the light-permeable hollow panel 2 is provided with an arc-shaped turning portion 9 protruding from an edge of the side surface. The arc-shaped part of the rotating part 9 and the edge of the side surface of the plate body are provided with limit grooves 20. The limit groove 20 is positioned at the position corresponding to the recessed groove body at the edge of the plate body and is used for limiting the rotation angle of the plate body.
The profile of the protruding turning part 9 is arc-shaped. The central axis of the radius of the rotating part 9 is located on the central plane 17 between the two sides of the plate body. As shown in fig. 9, the limit groove 20 is not limited to the V-shaped groove in the drawing, but may be a U-shaped groove, an arc-shaped groove, a square groove, a rectangular groove, or the like, as long as the rotation limit function of the plate body 21 can be achieved.
As shown in fig. 9 to 11, the plate bodies 21 are rotatably connected to each other by the connecting member 16 without having an acoustic transmission slit. The connected plates are arranged on the frame body 1.
The inventive way of not having an acoustically transparent slit means that there is no slit between the two plates which allows sound to penetrate the plates directly and propagate.
As shown in fig. 9 and 10 of the present invention, only a small curved gap exists between the plate 21 and the connecting member 16, and two edges of the plate 21 and two edges of the connecting member 16 overlap each other in space, so that the path of sound directly propagating through the gap is blocked, and the propagation range of sound is narrowed.
At least one end of the connection member 16 is provided with a concave rotation groove 11 that allows the rotation portion 9 to rotate. Preferably, as shown in fig. 11, both opposite ends of the connection member 16 are provided with concave-shaped rotating grooves 11. The shape of the rotary tub 11 includes at least an arc shape, a square shape, a rectangular shape, and a pyramid shape.
The rotating part 9 rotates in the rotating groove 11 at a slight angle so that the angle between the plate bodies can be adjusted, and thus the plate bodies form a sound barrier structure which is matched with the frame body 11 with radian and gives sound insulation through connection.
Fig. 9 to 11 show schematic cross-sectional views of the connection of the plate body 21 to the connecting member. When the plate 21 rotates, the rotating part 9 rotates in the rotating groove 11, and no obvious straight through gap is formed between the plate and the connecting member 16, so that sound cannot be directly transmitted through the gap between the plate and the connecting member 16.
Preferably, the edge of the rotating groove 11 of the connecting member 16 corresponds to the position of the limiting groove 20, so that a part of the edge of the connecting member 16 can be embedded into the limiting groove 20, and thus, when the rotating part 9 rotates, the edge of the connecting member 16 and the edge of the plate 21 are close to or even overlap as much as possible, the gap is reduced, the passage of sound through the air is reduced, and the sound insulation effect between the plate and the connecting member is improved. In particular, when the rotation is to the maximum extent, i.e. the maximum angle, the edge of the connecting member 16 contacts and is clamped with the edge of the plate 21, realizing the seamless connection of the two parts and completely blocking the transmission of sound.
Preferably, as shown in fig. 12, the micro angle at which the rotating portion 9 rotates in the rotating groove 11 ranges from 0 ° to ±10°. The micro-angle rotation between the plate bodies 21 is realized through the matching structure of the rotating parts 9 and the rotating grooves 11, so that the micro-angle rotation can be carried out between the plate bodies without gaps between the plate bodies and the connecting members, thereby realizing good sound insulation effect without accurately setting the position of the plate bodies by constructors, and the shape can be better installed and adjusted between the plate bodies and the frame body 1 due to the micro-angle adjusting structure. In particular, for a frame 1 having an arc or a bend, the micro-angle rotation of the plate can be more suitable for the shape of the frame.
In the present invention, the connection member 16 is not limited to a member dedicated for connection, and when the plate body or the steel column 7 is provided with the rotation groove 11, the plate body or the steel column 7 itself corresponds to a connection member, and adjacent plate bodies are connected in a micro-angle rotatable manner. As shown in fig. 5, the side surface of the first plate body 61 is provided with a rotation groove 11. The second plate 61 is provided with a rotation portion 9 on a side surface thereof.
The first plate body 61 and the second plate body 62 are connected to each other in a micro-angle rotatable manner.
As shown in fig. 4, when the bottommost sound baffle 6 needs to be fixed by the steel column 7, the bottom of the steel column 7 is fixed to the column by bolts. The bottom of the steel column 7 is provided with at least one support bar 8 extending laterally for providing a supporting force in a vertical direction to the connection members 16 in a lateral direction so that the sound barrier panel 6 and/or the light permeable hollow panel 2 connected to the same steel column 7 are in the same horizontal position, thereby reducing lateral errors between the panels in the same horizontal position.
Preferably, at least one connection member including the rotary tub 11 is provided at a side of the steel column 7 at the bottom of the frame 11. The steel column 7 is rotatably connected with the sound barrier plate 6 and/or the light-permeable hollow plate 2 in such a way that the rotation part 9 is matched with the rotation groove 11, so that the sound barrier plate 6 and/or the light-permeable hollow plate 2 rotate at a slight angle relative to the steel column 7.
The lower level sound barrier panel 6 will withstand the pressure exerted by the other upper panels, so that the sound barrier panel 6 in the bottom area is connected or supported by the steel columns 7, which can make the sound barrier panel 6 more stable. At the same time, the sound barrier panel 6 is arranged at a position close to the ground, so that noise transmitted to a high place can be reduced better.
Preferably, the connecting member 16 is a hollow member, the inside of which is filled with a sound-insulating component having a sound-insulating function, i.e., the entirety of the connecting member 16 is also a sound barrier member. When the connecting member 16 and the plate body 21 are rotated by a minute gap, sound is effectively absorbed and intercepted.
