Description

Technical Field

[0001] The utility model relates to the technical field of enclosures, in particular to an enclosure for highway construction. Background Technique

[0002] Construction projects must be fully enclosed, so enclosures need to be set up. The height of enclosures on main urban roads or where there is a large flow of people shall not be less than 2.5 meters, and the rest shall not be less than 1.8 meters. Generally, semi-enclosures are more common in municipal projects. The so-called semi-enclosure means that enclosures are set up on two or three sides.

[0003] The enclosure has the function of isolating the construction site from the outside world, preventing the impact of debris during construction on the outside world, and at the same time, it can also prevent irrelevant personnel from entering the construction site by mistake, causing unnecessary trouble. However, although the existing enclosures can physically isolate personnel and materials, the noise generated during construction is difficult to effectively block. In some cases, this noise will affect the normal life on both sides of the road.

[0004] Therefore, a new solution is needed to solve the above problems. Content of the Utility Model

[0005] (1) Technical Problems to be Solved

[0006] Aiming at the deficiencies of the prior art, the utility model provides an enclosure for highway construction, which solves the problems put forward in the above background technique.

[0007] (2) Technical Solutions

[0008] To achieve the above object, the utility model is realized through the following technical solutions: An enclosure for highway construction includes columns on both sides and a baffle arranged between the two columns. The baffle includes a sound insulation layer and a main body layer. Surface layers are arranged on the outer surfaces of both the main body layer and the sound insulation layer. A cavity is also arranged between the main body layer and the surface layer.

[0009] Preferably, the top end of the baffle bends towards the side close to the main body layer to form a bending part, and the length of the bending part accounts for 1 / 3 of the total length of the baffle.

[0010] Preferably, the thickness of the sound insulation layer is less than the thickness of the main body layer, and the thickness of the sound insulation layer is greater than the thickness of the cavity.

[0011] Preferably, the sound insulation layer is filled with honeycomb aluminum plates.

[0012] Preferably, the thickness of the cavity gradually decreases from bottom to top, and several strengthening strips are also arranged at intervals in the cavity.

[0013] Preferably, a buffer layer is arranged between the sound insulation layer and the surface layer.

[0014] (3) Beneficial effects

[0015] After adopting the above technical solution, compared with the prior art, the utility model has the following advantages:

[0016] By arranging a sound insulation layer inside the enclosure and using the honeycomb aluminum plate in the sound insulation layer to absorb and weaken the noise generated during the construction process to a certain extent, the influence of the noise on the outside is reduced, which is beneficial to the normal life around the construction site to a certain extent. In addition to supplementing the sound insulation ability of the enclosure, the cavity can also use the internal strengthening strips to strengthen the overall strength of the enclosure, making the overall enclosure have higher strength and thus obtaining a longer service life.

[0021] The following further elaborates on the utility model through the drawings and embodiments.

[0022] A road construction enclosure, as Figures 1-3As shown in the figure, it includes columns 1 on both sides and a baffle 2 arranged between the two columns 1. The columns 1 are used to support the structure of the enclosure. Multiple enclosures can form a complete surrounding function through the connection between the columns 1. The baffle 2 is the main shielding structure of the enclosure, which plays an actual isolation role between the inside and outside of the construction site. The baffle 2 includes a sound insulation layer 22 and a main body layer 21. Surface layers 23 are provided on the outer surfaces of both the main body layer 21 and the sound insulation layer 22. The surface layers 23 are used to protect the internal sound insulation layer 22 and main body layer 21. The main body layer 21 and the columns 1 form the complete structure of the enclosure. The sound insulation layer 22 can absorb or weaken the noise generated during the construction process inside the construction site to a certain extent, thereby playing a certain sound insulation effect. The sound insulation layer 22 is filled with honeycomb aluminum plates. The honeycomb aluminum plates can form honeycomb-shaped cavities in the sound insulation layer 22, thereby absorbing the noise. At the same time, since the honeycomb aluminum plates can also play a role in increasing the structural strength when used as filling, using this material can also improve the strength of the enclosure. A buffer layer is provided between the sound insulation layer 22 and the surface layer 23. The buffer layer can be used to absorb part of the impact force exerted on the enclosure from the outside. When an object impacts the enclosure from the outside, the buffer layer can protect the enclosure. A cavity 24 is also provided between the main body layer 21 and the surface layer 23. The thickness of the cavity 24 gradually decreases from bottom to top. A number of strengthening bars 25 are spaced apart in the cavity 24. The cavity 24 can also play a sound insulation effect to a certain extent, and in cooperation with the strengthening bars 25, it can further strengthen the enclosure.

[0023] The top end of the baffle 2 bends towards the side close to the main body layer 21 and forms a bending part 3. The length of the bending part 3 accounts for 1 / 3 of the total length of the baffle 2. The bending part 3 bends towards the construction site side, which can surround the upper part of the construction site to a greater extent and can strengthen the sound insulation ability of the enclosure to a certain extent and weaken the intensity of noise diffusion from above the construction site.

[0024] The thickness of the sound insulation layer 22 is less than the thickness of the main body layer 21, and the thickness of the sound insulation layer 22 is greater than the thickness of the cavity 24.

[0025] Based on the above embodiments as inspiration, through the above description, relevant staff can make various changes and modifications completely within the scope of not deviating from the idea of this invention. The technical scope of this utility model is not limited to the content in the specification, and its protection scope must be determined according to the scope of the claims.
