Detailed Description
The following detailed description is made with reference to the accompanying drawings.
The invention provides a sound barrier structure and a construction method thereof. The present invention can also provide a connecting member. The present invention can also provide a soundproof shed.
Example 1
A sound barrier structure, as shown in fig. 1 and fig. 2, at least comprising a frame body 1 with a radian, a plurality of sound barrier plates 6 and a plurality of light-permeable hollow plates 2. The rack 1 constitutes a rack having a curvature, thereby forming a frame having a top rack. The sound barrier panel 6 is a panel body capable of isolating and absorbing sound. The sound barrier panel 6 is, for example, a panel body filled with a sound absorbing material inside. 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 capable of sound insulation. The light-permeable hollow sheet 2 is, for example, a polycarbonate sheet, also called a solar sheet.
The plate body 21 constituting the sound barrier structure is not limited to the sound barrier panel 6 and the light-permeable hollow plate 2, and may include a see-through soundproof window 13. In the sound barrier structure, the sequence from low to high is as follows: a sound barrier plate 6, a light-permeable hollow plate 2; or as shown in fig. 8, the sound barrier panel 6, the see-through soundproof window 13, and the light-permeable hollow panel 2 are arranged in this 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 totally-closed shed, namely 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 in a shed body formed by the sound barrier structure is sufficient. Meanwhile, the light-permeable hollow plate 2 has the functions 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 disposed on the frame body 1 in such a manner that the first position thereof is lower than the second position of the light-transmitting hollow panel 2. The sound barrier panel 6 is arranged at a lower position, so that noise emitted by machinery on the construction ground can be fully absorbed, and the transmission range of the noise is reduced.
For example, the perspective sound insulation window body 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 the light near the ground and the energy consumption are reduced, and the energy-saving and environment-friendly effects are achieved. The perspective sound insulation window body 13 is made of safety glass with an interlayer arranged in the middle and glued, and has a sound insulation function while transmitting light. Preferably, the height of the sound barrier region 4 is preferably 3.
Preferably, as shown in fig. 2, in a section with low construction noise, the sound barrier area 4 in the sound barrier structure may not be provided with the sound barrier panel 6, and the see-through hollow panel 2 and/or the steel wire mesh 5 are/is replaced to support the top canopy body formed by the see-through hollow panel 2, so as to realize local sound insulation and rain shielding effects.
Among 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 syllable-dividing effect. However, because the plate bodies are connected by using the common steel column 7, gaps between the steel column 7 and the plate and between the plate bodies are still large, so that noise is transmitted through the gaps, and a good sound insulation effect is not achieved. Meanwhile, as constructors need to consume a large amount of energy and time in order to maintain the deformation-free connection and accurate splicing of the plate bodies, the construction efficiency is low.
In order to solve the problems, the invention improves the edge structure and the connecting members of the plate bodies, so that even if the construction precision is reduced by constructors, the gaps between the plate bodies can be smaller or even not remained, the sound insulation effect is improved, and the construction efficiency of the constructors can also be improved.
Fig. 3 to 8 show different plate bodies 21 with different sound barrier structures from low to high. As shown in fig. 3 to 8, the sound barrier panel 6 is provided near the ground, and the sound barrier panel 6 is provided on the pre-buried pillar. The steel column 7 is stably and vertically arranged through the upright column. In the upright region of the sound barrier structure, steel columns 7 maintain the panel in an upright shape and angle. When two boards need to be slightly bent, the steel column 7 is not used, so that the angle change of the board body can adapt to the radian change of the frame body 1. In the present invention, the plate 21 refers to any plate constituting the sound barrier structure.
Preferably, as shown in fig. 8, when the see-through hollow plate 2 is provided at the top of the frame body 1, it is possible to provide the diagonal bracing assembly 14 and the longitudinal bracing assembly 15 in the rectangular frame consisting of the two steel columns 7 and the connecting 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-transmissive 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 limiting grooves 20. The limiting groove 20 is a groove body which is recessed relative to 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 turning part 9 is located in the centre plane 17 between the two sides of the plate body. As shown in fig. 9, the limiting groove 20 is not limited to the V-shaped groove in the figure, and may be a U-shaped groove, an arc-shaped groove, a square-shaped groove, a rectangular groove, or the like, as long as the function of limiting the rotation 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 acoustically transparent gap. The connected plate bodies are arranged on the frame body 1.
The mode of the present invention without the sound-transmitting gap means that a gap which allows sound to directly penetrate through the plate body and propagate is not provided between the two plate bodies.
As shown in fig. 9 and 10 of the present invention, only a slight curved gap exists between the plate body 21 and the connecting member 16, and two edges of the plate body 21 and two edges of the connecting member 16 are overlapped in space, so that a path through which sound is directly transmitted through the gap is blocked, and a transmission range of sound is narrowed.
At least one end of the connecting member 16 is provided with a concave-shaped rotation groove 11 that allows the rotation of the rotating portion 9. Preferably, as shown in fig. 11, opposite ends of the connecting member 16 are provided with concave rotation grooves 11. The shape of the rotary groove 11 includes at least arc, square, rectangular and pyramid.
The rotating part 9 rotates at a slight angle in the rotating groove 11 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 a radian and gives sound insulation through connection.
Fig. 9 to 11 are schematic cross-sectional views illustrating the connection of the plate body 21 and the connecting member. When the plate body 21 rotates, the rotating portion 9 rotates in the rotating groove 11, no obvious and straight-through gap is formed between the plate body and the connecting member 16, so that sound cannot be directly transmitted through the gap between the plate body 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 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 body 21 are as close as possible or even overlap, the gap is reduced, the passage of sound through air is reduced, and the sound insulation effect between the plate body and the connecting member is improved. In particular, when the rotation is made to the maximum amplitude, i.e. at the maximum angle, the edge of the connecting member 16 comes into contact with and blocks the edge of the plate 21, achieving a seamless connection of the two parts, completely blocking the transmission of sound.
Preferably, as shown in fig. 12, the micro-angle range in which the rotating portion 9 rotates in the rotating groove 11 is 0 ° to ± 10 °. The rotation of the micro-angle between the plate bodies 21 is realized through the matching structure of the rotating part 9 and the rotating groove 11, so that the plate bodies can be rotated in a micro-angle mode without gaps between the plate bodies and connecting members, good sound insulation effect can be achieved without accurately setting the positions of the plate bodies by constructors, and due to the existence of the micro-angle adjusting structure, the shape can be better installed and adjusted between the plate bodies and the support body 1. Particularly for the shelf body 1 with radian or bending, the micro-angle rotation of the plate body can be more suitable for the shape of the shelf body.
In the present invention, the connecting member 16 is not limited to a dedicated connecting component, and when the plate or the steel column 7 is provided with the rotary slot 11, the plate or the steel column 7 itself also serves as a connecting member for connecting adjacent plates in a slightly rotatable manner. As shown in fig. 5, the first plate 61 is provided with a rotary groove 11 on a side surface thereof. The side surface of the second plate 61 is provided with a rotating portion 9.
The first plate 61 and the second plate 62 are connected to each other in a slightly rotatable manner.
As shown in fig. 4, when the bottommost sound barrier panel 6 needs to be fixed by the steel columns 7, the bottoms of the steel columns 7 are fixed to the columns by bolts. The bottom of the steel column 7 is provided with at least one support bar 8 extending in the transverse direction for providing a support force in the vertical direction to the connection member 16 in the transverse direction so that the sound barrier panel 6 and/or the light-transmissive hollow panel 2 connected to the same steel column 7 are at the same horizontal position, thereby reducing a lateral error between panels at the same horizontal position.
Preferably, at least one connecting member including a rotary slot 11 is provided at the bottom of the frame body 11 at the side of the steel column 7. The steel columns 7 are rotatably connected to the sound barrier panel 6 and/or the light-permeable hollow panel 2 in such a manner that the rotating portions 9 are matched with the rotating grooves 11, so that the sound barrier panel 6 and/or the light-permeable hollow panel 2 are rotated at a slight angle with respect to the steel columns 7.
Because the lower sound barrier panel 6 of horizontal position can bear the pressure that other plate bodies in upper portion exerted, therefore the sound barrier panel 6 of bottom region is connected or is supported by steel column 7, can make sound barrier panel 6 more firm. Meanwhile, the sound barrier plate 6 is arranged close to the ground, so that noise transmitted to a high place can be reduced better.

The connecting member 16 is provided with at least one extending portion 18 extending in an orthogonal direction to the axial direction of the connecting member. The end of the extension 18 is provided with at least one hole 19 matching the stud.
With the stud inserted into the hole 19 and fixed in a rotatable manner, the plate body is connected with the connecting member and can be adjusted in a slight angle with respect to the connecting member. So set up for plate body and connecting element inseparable, do not hinder the rotation of plate body simultaneously.
Preferably, the connecting member is a laterally unbent cylinder, as shown in fig. 11.
The connecting member is a cylinder having a bending angle in a direction orthogonal to the axial direction of the connecting member, so that at least two plate bodies connected by the connecting member are disposed oppositely at a large angle, as shown in fig. 11.
The invention also provides a construction method of the sound barrier, which at least comprises the following steps:
s1: the sound barrier panel 6 is disposed on the frame body 1 in such a manner that the first position thereof is lower than the second position of the light-transmitting hollow panel 2.
S2: the plurality of sound barrier panels 6 and/or the plurality of light-permeable hollow panels 2 are rotatably connected by a connecting member without an acoustically transparent gap and are disposed on the frame body 1.
