Description

Technical Field

[0001] This utility model belongs to the field of sound barrier installation, specifically relating to a detachable sound barrier pre-embedded connecting sleeve. Background Technology

[0002] Pre-embedded connecting sleeves for sound barriers are accessories used for installing sound barriers. They are commonly used in traffic noise control projects such as highways, railways, and airports. Their function is to firmly connect the sound barrier to the supporting structure (such as columns) while also providing a certain degree of sound insulation. Pre-embedded connecting sleeves are generally embedded in the concrete foundation in advance to facilitate subsequent installation and adjustment.

[0003] Most existing sound barriers have pre-embedded connecting sleeves that are embedded in concrete anchor blocks. This results in the pre-embedded connecting sleeve and the concrete anchor block being an integrated structure. However, after the sound barrier is installed on the pre-embedded connecting sleeve, users often need to disassemble and maintain the sound barrier and the pre-embedded connecting sleeve as the usage time increases. The integrated pre-embedded connecting sleeve and the concrete anchor block are difficult to separate, which leads to high maintenance costs for the sound barrier. Moreover, the disassembly process can easily cause significant damage to the concrete anchor block, thereby affecting its service life.

[0004] Therefore, in response to the problems of existing sound barrier pre-embedded connecting sleeves being inconvenient to disassemble during use and easily causing significant damage to the concrete foundation, a detachable sound barrier pre-embedded connecting sleeve was developed. By adding a threaded disassembly structure and a sleeve auxiliary fixing structure to the pre-embedded connecting sleeve, users can easily disassemble and maintain the sound barrier, and reduce the impact on the concrete foundation during the disassembly of the pre-embedded sleeve 4. Utility Model Content

[0005] In order to overcome the problem that the existing pre-embedded connecting sleeves of the sound barrier are inconvenient to disassemble during use and are prone to causing significant damage to the concrete foundation.

[0006] The technical solution of this utility model is as follows: a detachable sound barrier pre-embedded connecting sleeve, including a pre-embedded base, a pre-embedded shell, an anchor plate, and a pre-embedded sleeve. A pre-embedded screw is fixedly connected to the upper center of the pre-embedded base. A threaded layer is provided on the outer wall of the pre-embedded shell. Two sets of first through holes are symmetrically distributed on the left and right sides through the outer wall of the pre-embedded shell. A bearing plate is fixedly connected to the upper end of the pre-embedded sleeve. An upper threaded groove is opened through the upper center of the bearing plate. A lower threaded groove is opened at the lower center of the pre-embedded sleeve. A connecting screw is fixedly connected to the lower center of the anchor plate.

[0007] Preferably, the upper end of the pre-embedded base is provided with a connecting groove, and the lower end of the pre-embedded shell is installed in the connecting groove.

[0008] Preferably, the lower screw groove is threaded to the pre-embedded screw, and the upper screw groove is threaded to the connecting screw.

[0009] Preferably, the upper end of the anchor plate is fixed with ear plates symmetrically distributed on the left and right, and the connection between the ear plates and the anchor plate is fixed with stiffening plates symmetrically distributed on the front and back.

[0010] Preferably, the anchor plate has second through holes symmetrically distributed at both the upper and lower edges, and handles symmetrically distributed at the upper edge of the bearing plate are fixed thereon. The second through holes and handles are located between the two sets of stiffening plates.

[0011] Preferably, the handle passes through the second through hole and is located at the upper end of the anchor plate, while the lower end of the anchor plate is in contact with the upper end of the bearing plate.

[0012] Preferably, the upper end of the pre-embedded outer shell is fitted with the lower end of the bearing plate, and the pre-embedded outer shell covers the pre-embedded screw and the pre-embedded sleeve on its inner wall.

[0013] The beneficial effects of this utility model are:

[0014] 1. By using the pre-embedded shell and the first through hole, the amount of concrete entering the pre-embedded shell during pouring can be reduced, thereby preventing the concrete from fixing and locking the threaded pre-embedded sleeve and pre-embedded screw during pouring, thus reducing the impact on the concrete foundation during the disassembly of the pre-embedded sleeve.

[0015] 2. The pre-embedded base, pre-embedded sleeve and anchor plate connected by threaded connection can be quickly disassembled by the user, so as to facilitate the user's subsequent maintenance of the sound barrier. Attached Figure Description

Detailed Implementation

[0024] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0025] Please see Figures 1-7 This utility model provides an embodiment of a detachable sound barrier pre-embedded connecting sleeve, including a pre-embedded base 1, a pre-embedded outer shell 2, an anchor plate 3, and a pre-embedded sleeve 4. A pre-embedded screw 6 is fixedly connected to the upper center of the pre-embedded base 1. A threaded layer 7 is provided on the outer wall of the pre-embedded outer shell 2. Two sets of first through holes 8 are symmetrically distributed on the left and right sides through the outer wall of the pre-embedded outer shell 2. A bearing plate 9 is fixedly connected to the upper end of the pre-embedded sleeve 4. An upper threaded groove 10 is provided through the upper center of the bearing plate 9. A lower threaded groove 12 is provided at the lower center of the pre-embedded sleeve 4. A connecting screw 16 is fixedly connected to the lower center of the anchor plate 3.

[0026] The amount of concrete entering the pre-embedded housing 2 during pouring can be reduced by using the pre-embedded housing 2 and the first through hole 8. This prevents the concrete from locking the threaded pre-embedded sleeve 4 and the pre-embedded screw 6 during pouring, thus reducing the impact on the concrete foundation during the disassembly of the pre-embedded sleeve 4. The threaded pre-embedded base 1, the pre-embedded sleeve 4 and the anchor plate 3 can be quickly disassembled by the user, making it easier for the user to maintain the sound barrier in the future.

[0027] Please see Figures 3-5In this embodiment, the upper end of the pre-embedded base 1 is provided with a connecting groove 5, and the lower end of the pre-embedded shell 2 is installed in the connecting groove 5. The connecting groove 5 can limit the bottom of the pre-embedded shell 2 to prevent the pre-embedded shell 2 from shifting or bending during the pouring process. The upper end of the pre-embedded shell 2 is in contact with the lower end of the bearing plate 9. The pre-embedded shell 2 covers the pre-embedded screw 6 and the pre-embedded sleeve 4 on its inner wall. The pre-embedded shell 2 can cover the pre-embedded screw 6 and the pre-embedded sleeve 4 inside for protection to prevent the concrete from fixing the pre-embedded sleeve 4 and affecting the disassembly of the pre-embedded sleeve 4.

[0028] Please see Figures 4-7 In this embodiment, the upper end of the anchor plate 3 is fixed with symmetrically distributed ear plates 13. The connection between the ear plates 13 and the anchor plate 3 is fixed with symmetrically distributed reinforcing plates 14. The reinforcing plates 14 can improve the firmness of the sound barrier installed on the ear plates 13. The upper and lower edges of the anchor plate 3 are provided with symmetrically distributed second through holes 15. The upper edge of the bearing plate 9 is fixed with symmetrically distributed handles 11. The second through holes 15 and the handles 11 are located between the two sets of reinforcing plates 14. The second through holes 15 can expose the handles 11 at the upper end of the anchor plate 3. The handles 11 pass through the second through holes 15 and are located at the upper end of the anchor plate 3. The lower end of the anchor plate 3 is in contact with the upper end of the bearing plate 9. The handles 11 can be easily pulled out of the poured concrete by the user using a wrench.

[0029] Please see Figures 3-7 In this embodiment, the lower screw groove 12 is threadedly connected to the pre-embedded screw 6, and the upper screw groove 10 is threadedly connected to the connecting screw 16. The threaded connection of the pre-embedded base 1, the pre-embedded sleeve 4, and the anchor plate 3 makes it easy for the user to disassemble the pre-embedded sleeve 4 and the anchor plate 3.

[0030] In use, the pre-embedded base 1, pre-embedded shell 2 and pre-embedded sleeve 4 are first cast in place in a suitable position, and the upper end of the pre-embedded sleeve 4 is exposed on the cast-in-place concrete. At the same time, the concrete will slowly flow into the pre-embedded shell 2 through the first through hole 8 to fill and fix the pre-embedded screw 6 and the pre-embedded sleeve 4, so as to fix the pre-embedded screw 6 and the pre-embedded sleeve 4 to a certain extent. The threaded layer 7 on the outside of the pre-embedded shell 2 can make the concrete fully contact the pre-embedded shell 2, so that the pre-embedded base 1 and the pre-embedded shell 2 are firmly fixed in the cast-in-place concrete.

[0031] After the concrete is poured and solidified, the anchor plate 3 is installed into the upper screw groove 10 at the upper end of the pre-embedded sleeve 4 by connecting screw 16, so that the lower end of the anchor plate 3 fits with the upper end of the bearing plate 9. Then the sound barrier is installed onto the ear plate 13 by bolts.

[0032] When it is necessary to disassemble the sound barrier, simply remove the sound barrier and anchor plate 3 from the internal thread of the pre-embedded sleeve 4.

[0033] Then, due to the obstruction of the pre-embedded shell 2, the amount of concrete entering the pre-embedded shell 2 is relatively small. It is only necessary to use a wrench to hold the handle 11 to pry the pre-embedded sleeve 4 out of the pre-embedded shell 2, and then unscrew the pre-embedded sleeve 4 out of the foundation concrete. The pre-embedded base 1 and the pre-embedded screw 6 are buried in the cast-in-place concrete. Later, it is only necessary to seal the pre-embedded sleeve 4, thus having a small impact on the concrete foundation.

[0034] Through the above steps, the amount of concrete entering the pre-embedded housing 2 during pouring can be reduced by using the pre-embedded housing 2 and the first through hole 8. This prevents the concrete from locking the threaded pre-embedded sleeve 4 and the pre-embedded screw 6 during pouring, thus reducing the impact on the concrete foundation during the disassembly of the pre-embedded sleeve 4. The threaded pre-embedded base 1, pre-embedded sleeve 4 and anchor plate 3 can be quickly disassembled by the user, making it convenient for the user to maintain the sound barrier. This solves the problem that the existing pre-embedded connecting sleeves of sound barriers are inconvenient to disassemble during use and are prone to causing significant damage to the concrete foundation.

[0035] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
