Description

Technical Field

[0001] The invention belongs to the technical field of noise reduction equipment, in particular to a noise reduction device for building construction and an installation method thereof. Background Art

[0002] Construction noise refers to the noise generated by the construction of public facilities such as subways, highways, bridges, the laying of underground pipelines and cables, as well as industrial and civil construction sites in cities, which use a large number of power machinery with different performances, turning the originally relatively quiet environment into a place with serious noise pollution.

[0003] In order to reduce the impact of construction noise on residents and the environment, my country has issued a series of noise control standards and regulations, requiring construction sites to take effective noise reduction measures. Among them, noise reduction fences are widely used in various construction sites as a noise reduction device with good noise reduction effect, wide installation requirements and strong environmental adaptability. However, traditional noise reduction fences often have problems such as complex structure, cumbersome installation and inconvenient transportation, which are difficult to meet the needs of modern construction for efficiency, environmental protection and convenience. In addition, the construction of traditional fences requires a lot of manpower and time costs, which is not economical and efficient in short-term construction projects.

[0004] The related art discloses a fence device for civil engineering construction that is easy to reduce noise, application number: CN202220271259X. In this scheme, a circular tube and a rolled cloth are used as the main body of the fence. In the early preparation process of the construction, the rolled cloth is unfolded and surrounded around the periphery of the construction site to block the propagation of noise and achieve the effect of noise reduction. However, in actual application, it is found that, on the one hand, the rolled cloth composed of a thin layer of sound insulation felt has a poor noise blocking effect, so the noise blocking effect of the fence is not ideal. On the other hand, the rolled cloth itself is a soft structure.

DETAILED DESCRIPTION

[0042] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0043] like Figures 1 to 10 As shown, a noise reduction device for construction according to the present invention comprises alternately connected columns and noise reduction belts;

[0044] The noise reduction belt is a multi-layer structure consisting of a sound insulation felt 1, a sound absorbing sponge 11 and an expansion body, wherein the sound absorbing sponge 11 and the sound insulation felt 1 are symmetrically distributed on both sides of the expansion body in sequence;

[0045] The expansion body is made of a hollow hose, and a connecting hole 14 is opened at one end of the expansion body. In the initial state, the connecting hole 14 is blocked by a sealing plug, and the expansion coefficient of the bottom of the expansion body is greater than the expansion coefficient of the top;

[0046] In the initial state, the expansion body is contracted and the noise reduction belt is a sheet-like structure;

[0047] In the working state, the expansion body is pressurized, the thickness of the noise reduction belt increases, and the thickness of the bottom end of the noise reduction belt is greater than the thickness of the top end;

[0048] The columns are hingedly mounted with symmetrically arranged diagonal braces 2, and the diagonal braces 2 and the noise reduction belts are arranged in a cross shape on the side walls of the columns.

[0049] The expansion body includes a water storage bag 12 and an extension tube 13. The water storage bag 12 is located at the bottom of the noise reduction belt. The extension tube 13 is fixedly installed on the water storage bag 12. The extension tube 13 extends to the top of the noise reduction belt.

[0050] In the preparation phase before construction, workers need to erect and surround the noise reduction fence outside the construction site. In order to enhance the convenience of transportation and installation of the noise reduction fence, and at the same time to enhance the stability and noise reduction effect of the noise reduction fence, the present invention improves the columns and noise reduction belts that constitute the noise reduction fence.

[0051] Specifically, when constructing the noise reduction fence, the staff uses transportation equipment to transport the noise reduction fence in a rolled state to the construction site, and then gradually unfolds the noise reduction fence from one end. During the unfolding of the noise reduction fence, the diagonal braces 2 are opened one by one, and the noise reduction belt is initially fixed using the diagonal braces 2 and the columns. At the same time, the water supply equipment is connected to the connecting hole 14 using a pipe, and the water supply equipment pumps water into the expansion body. Since the expansion body includes a water storage bag 12 and an extension tube 13, and the expansion body is made of a hollow hose, the expansion body gradually deforms from a flat state to an expanded state under the action of water pressure. At the same time, because the expansion body is installed on the inner side of the sound insulation felt 1 and the sound-absorbing sponge 11, the thickness of the noise reduction belt gradually increases under the support of the expansion body. When the noise reduction fence is fully unfolded and the water pressure in the expansion body reaches a preset value At this time, the thickness of the noise reduction belt reaches an ideal state. At the same time, because the larger water storage bag 12 is installed at the bottom of the noise reduction belt, and the smaller extension tubes 13 are vertically installed at equal intervals in the middle and upper part of the noise reduction belt, when the expansion body is filled with water, the noise reduction belt as a whole presents a state of small thickness at the upper end and large thickness at the lower end. Combined with the supporting effect of the columns and the diagonal braces 2, the noise reduction enclosure is stably erected on the ground. When the construction noise is transmitted in the air, the thickness of the noise reduction belt is increased. When the construction is completed, the staff will open the connecting hole 14 blocked by the sealing plug again, and use natural dumping or mechanical extraction to discharge the water flow inside the expansion body. After the water flow is discharged, the thickness of the noise reduction belt will not only shrink rapidly, but also its weight will be reduced. After the staff winds and bundles the noise reduction enclosure, it can wait for the next use.

[0052] The present invention arranges an expansion body in the noise reduction belt and utilizes the difference in expansion coefficients of the expansion body at the top and bottom ends of the noise reduction belt, so that the noise reduction belt after installation is thinner at the top and thicker at the bottom. On the one hand, the noise reduction effect on near-ground noise is enhanced, reducing the impact of noise on people close to the ground; on the other hand, the center of gravity of the noise reduction enclosure is brought close to the ground, thereby improving the stability of the noise reduction enclosure. At the same time, the shrinkage effect of the expansion body is utilized, so that after use, the noise reduction enclosure can be rolled up and transported more conveniently through volume contraction and weight reduction.

[0053] As a preferred embodiment of the present invention, the noise reduction belt is fixedly installed with evenly distributed installation rods 25, and the bottom of the installation rods 25 are hingedly installed with a deformation frame 26, and the deformation frame 26 is hinged by four connecting rods. The bottom of the noise reduction belt is located inside the deformation frame 26, and the deformation frame 26 is provided with an elastic groove 27. An elastic belt 28 is installed in the elastic groove 27. The deformation frame 26 is triangular under the tension of the elastic belt 28.

[0054] Since the liquid is fluid and the material hardness of the noise reduction belt is insufficient, in order to further enhance the restriction on the shape of the bottom end of the noise reduction belt, the bottom end of the noise reduction belt presents a triangle with strong stability, so that the noise reduction belt can be stably erected on the ground. In the present invention, mounting rods 25 are evenly installed on the noise reduction belt, and the mounting rods 25 are fixedly connected to the noise reduction belt by bolts. At the same time, a deformation frame 26 is arranged at the bottom of the mounting rod 25, and the deformation frame 26 is used to cover the bottom end of the noise reduction belt. In the initial state, the deformation frame 26 in the winding state is under pressure. , and presents a quadrilateral, and the deformable frame 26 fits on the noise reduction belt. When the noise reduction enclosure is unfolded, the deformable frame 26 loses its restriction, and under the pulling force of the elastic band 28, the deformable frame 26 unfolds, and cooperates with the accumulation of water in the water storage bag 12. When the deformable frame 26 is supported by the ground, compressed by the water storage bag 12 and pulled by the elastic band 28 at the same time, the deformable frame 26 presents a triangle, thereby restricting the shape of the water storage bag 12, causing the bottom end of the noise reduction belt to be approximately triangular, and cooperates with the column to enhance the stability of the noise reduction enclosure.

[0055] As a preferred embodiment of the present invention, the deformation frame 26 is provided with a plurality of symmetrical adjustment slots 3, the adjustment slots 3 are conductively connected to the elastic slots 27, and plug blocks 31 are fixedly installed at both ends of the elastic band 28, the plug blocks 31 match the adjustment slots 3, and the plug blocks 31 are used to cooperate with the adjustment slots 3 to adjust the elastic force of the elastic band 28.

[0056] In order to facilitate the adjustment of the elasticity of the deformation frame 26 and make the deformation condition of the deformation frame 26 more flexible, in the present invention, a plurality of adjustment slots 3 are provided on the deformation frame 26, and the plurality of adjustment slots 3 are symmetrically distributed at both ends of the elastic slot 27, and plug blocks 31 are fixedly installed at both ends of the elastic band 28. When adjusting the elasticity of the elastic band 28, the staff only needs to manually pull the plug block 31 and insert the plug block 31 into the adjustment slot 3 at different positions. When the extension path of the elastic band 28 between the two plug blocks 31 is extended, the elasticity of the deformation frame 26 is increased, and vice versa. This reduces the elasticity of the deformable frame 26. When the noise reduction enclosure is rolled up, the elasticity of the deformable frame 26 is reduced, which can facilitate the fit of the deformable frame 26 and enhance the convenience of rolling up the noise reduction enclosure. When the noise reduction enclosure is unfolded and erected, the elasticity of the deformable frame 26 is increased, which can enhance the deformation ability of the deformable frame 26 in the thickness direction of the noise reduction enclosure. At the same time, in actual application, the staff can adjust the elasticity of the deformable frame 26 by themselves, so that the deformable frame 26 presents a triangular stability that is stronger under the effects of elasticity, gravity of the water storage bag 12 and ground restrictions.

[0057] As a preferred embodiment of the present invention, the column includes a connecting piece 21 and a column 22, the connecting piece 21 is fixedly connected to the noise reduction belt, a pressing groove 23 is provided on the column 22, the connecting piece 21 extends into the pressing groove 23, and the connecting piece 21 is slidably connected to the main body through the pressing groove 23.

[0058] A spring-type telescopic foot 24 is fixedly mounted on the bottom of the column.

[0059] In order to further enhance the stability of the noise reduction enclosure, the column in the present invention is composed of a connecting piece 21 and a column 22, wherein the connecting piece 21 is mainly used to connect the noise reduction belt. When the noise reduction belt is filled with water, the thickness of the bottom end of the noise reduction belt increases, the height decreases, and the weight increases. At this time, under the action of gravity, the noise reduction belt pulls the connecting piece 21 to slide downward, and finally the connecting piece is pressed on the column 22. At the same time, the bottom end of the noise reduction belt contacts the ground. In this process, due to the spring telescopic foot 24 installed at the bottom end of the column 22, the column 22 has a tendency to move toward the ground under the action of gravity, and the diagonal brace 2 has been fully unfolded at this time. Therefore, when the column 22 moves downward, downward pressure is applied to the top end of the diagonal brace 2, thereby making the combination of the diagonal brace 2 and the ground more stable, thereby ultimately enhancing the stability of the column on the ground.

[0060] As a preferred embodiment of the present invention, a spray pipe 4 is fixedly installed at the top of the extension tube 13, and evenly distributed high-pressure spray heads are installed on the spray pipe 4. A connecting pipe 41 is fixedly installed between two adjacent columns 22, and the connecting pipe 41 is conductively connected to the spray pipe 4.

[0061] In actual application, since construction sites usually have a lot of dust, a spray pipe 4 is installed at the bottom end of the extension pipe 13 in the present invention. When the water supply equipment pumps water into the extension pipe 13, as the water pressure continues to increase, water is sprayed out from the high-pressure spray head on the spray pipe 4 and sprayed into the air in the form of water mist. The presence of water mist can not only reduce dust in the air, but also cause a certain obstruction to the propagation of sound. At the same time, during the falling process of water mist, it adheres to the surface of the noise reduction belt, blocks the pores on the surface of the noise reduction belt, and further enhances the noise blocking effect of the noise reduction belt.

[0062] As a preferred embodiment of the present invention, a connecting cavity 42 is opened inside the column 22, and the connecting cavity 42 is used to connect two adjacent connecting pipes 41. A hydraulic telescopic rod 43 is installed on the column 22, and the hydraulic telescopic rod 43 is connected to the connecting cavity 42 through a pipeline. The hydraulic telescopic rod 43 is located below the diagonal brace 2.

[0063] When water is pumped into the expansion body, the water flows into the connecting cavity 42 through the expansion body, and flows in the expansion body in the entire noise reduction enclosure through the conducting effect of the connecting cavity 42. On the one hand, during the construction of the noise reduction enclosure, it is only necessary to connect the connecting holes 14 on one of the noise reduction belts with the water supply equipment to allow the water to flow into multiple expansion bodies. On the other hand, the convenience of water filling is enhanced. On the other hand, as the water pressure in the connecting cavity 42 gradually increases, the water pressure acts on the hydraulic telescopic rod 43, causing the hydraulic telescopic rod 43 to extend, thereby supporting the unfolded diagonal brace 2. At this time, the diagonal brace 2 is at the maximum opening angle and is supported by the hydraulic telescopic rod 43, so that the angle between the diagonal brace 2 and the column 22 is relatively fixed, thereby reducing the probability of the column tipping over when the column is impacted by external force.

[0064] As a preferred embodiment of the present invention, the connecting cavity 42 is a U-shaped cavity, a cutting groove 5 is provided on the column 22, the cutting groove 5 is connected to the connecting cavity 42, a valve core 51 is elastically installed in the cutting groove 5 by a spring, the hydraulic telescopic rod 43 extends into the valve core 51, and an opening is set at the end of the valve core 51.

[0065] When the valve core 51 is pressed by the diagonal brace 2 and fits the inner wall of the conducting cavity 42, the opening of the hydraulic telescopic rod 43 is blocked, and the water pressure will not act on the inner wall of the hydraulic telescopic rod 43.

[0066] A method for installing a noise reduction device for building construction, the method comprising the following steps:

[0067] S1: The noise reduction device in the rolled state is transported to the construction site by using transportation equipment, and then the staff gradually unfolds the noise reduction device at the pre-planned construction location;

[0068] S2: Manually pull open the diagonal braces 2 on both sides of the column to fully open the noise reduction device, and then use a pipe to connect the connecting hole 14 to the water supply equipment;

[0069] S3: The water flows into the expansion body and diffuses into the entire noise reduction device along the spray pipe 4, the connecting pipe 41 and the connecting cavity 42, causing the noise reduction belt to expand;

[0070] S4: Under the combined effect of water pressure and the deformation frame 26, the bottom end of the noise reduction belt gradually expands into a triangle. At the same time, under the effect of the gravity of the water, the noise reduction belt and the connecting member 21 descend, so that the column is stably supported on the ground;

[0071] S5: When the water pressure in the expansion body rises to a preset value, water is sprayed out from the high-pressure spray head on the spray pipe 4 to form water mist, which cooperates with the noise reduction belt to block the propagation of noise.
