Description

Structure between sound barrier plates

Technical Field

The utility model relates to a sound barrier technical field, more specifically relates to structural design between the sound barrier cell board.

Background

The sound barrier is mainly used for sound insulation and noise reduction of highways, expressways, overhead composite roads and other noise sources. The sound insulation method is divided into a reflection type sound barrier for pure sound insulation and a composite type sound barrier for combining sound absorption and sound insulation, and the latter is a more effective sound insulation method. Refers to a wall structure provided beside railways and highways to reduce the influence of driving noise on nearby residents. Sound-insulating walls are also known as sound barriers. The insertion of a facility between the source and the receiver, called a sound barrier, provides a significant additional attenuation of the sound wave propagation, thus attenuating the noise contribution in the area where the receiver is located. The most used types of sound barriers are classified into traffic sound barriers, equipment noise attenuation sound barriers, industrial plant sound barriers, highways and expressways. The sound barrier mainly comprises a steel structure upright post and a sound absorption barrier plate, wherein the upright post is a main stressed member of the sound barrier and is fixed on a road anti-collision wall or an embedded steel plate at the edge of a track through bolts or welding; the sound absorption and insulation board is a main sound insulation and absorption component and is fixed in the H-shaped upright post groove through a high-strength spring clip to form a sound barrier. The design of the sound barrier fully considers the problems of wind load of elevated highways, urban light rails and subways, impact safety of traffic vehicles and all-weather outdoor corrosion prevention. The sound insulation and noise reduction device has the advantages of attractive and elegant appearance, delicate manufacture, convenient transportation and installation, low manufacturing cost and long service life, is particularly suitable for noise prevention of elevated highways and urban light rails and subways, and is an ideal sound insulation and noise reduction facility for modern cities.

Heretofore, the joint portions of both ends of the sound barrier panel have been made of metal or other materials having high rigidity, and a rectangular rubber pad has been often used between the panels in order to reduce friction between the panels of the sound barrier panel and to prevent water leakage from a gap between the panels. However, the design of the inter-plate structure has short service life, the problem of water leakage can occur in 3-5 years generally, and the structure can not meet the requirement of arranging waterproof on the top of the circular arc-shaped totally-enclosed sound barrier, so that the water leakage condition can be immediately caused, and a larger water curtain hole phenomenon can be formed.

Example 1:

as shown in fig. 1 and 2, which illustrate schematic cross-sectional views of a sound barrier panel-to-panel structure according to a first embodiment of the present invention, an inter-panel structure 100 is provided at a joint portion of an upper sound barrier cell panel 200 and a lower sound barrier cell panel 300. The waterproof and anti-abrasion device is used for preventing water and abrasion between plates and preventing vibration during installation. Fig. 2 is an enlarged view of fig. 1. Fig. 3 is a perspective view showing the inter-panel structure 100 according to the present embodiment, and fig. 4 is a cross-sectional view of fig. 3. The sound barrier inter-plate structural member adopts an inter-plate elastic gasket between two adjacent upper and lower shield plates, and the length of the inter-plate elastic gasket is equal to that of the joint part of the two adjacent upper and lower shield plates; preferably, the elastic strips between the plates are made of ethylene propylene diene monomer.

As shown in fig. 2 and 4, the present embodiment shows the structure between boards of the present invention, which includes: the intermediate bent portion 1, the first and

second support portions

21 and 22, and the first and second

side wing portions

31 and 32. The plate-to-plate structural member of the present embodiment is described in detail below.

The middle bending part 1 is located between the protrusion 301 and the groove 201 of the two adjacent sound

barrier unit panels

200 and 300, and the thickness of the middle bending part 1 is smaller than that of the groove 201, and the middle bending part 1 is not attached to the protrusion 301 and the groove 201, but has a certain preset distance. As a preferable mode of the preset distance, the preset distance is 1-5 mm.

The first support part 21 and the second support part 22 are arranged on both sides of the middle bending part 1. The thicknesses of the first supporting portion 21 and the second supporting portion 22 are greater than that of the middle bent portion, and the first supporting portion and the second supporting portion are tightly attached to the two adjacent sound

barrier unit panels

200 and 300. The thickness of the first support part 21 and the second support part 22 is 1 to 5 times, preferably 3 times, the thickness of the middle bending part. In the implementation, the thickness of the first supporting part and the second supporting part is 2-6 mm; the thickness of the middle bending part is 1-3 mm. After long-term tracking research, water is easy to enter gaps between plates if the same-thickness spacers between the plates are adopted. Through analysis, the pressure between the plates is large in the middle and small in the two sides, which is the main reason for water seepage between the plates. Meanwhile, the gaps between the plates are contacted with the outside to form positions, so that the gaskets between the plates are easy to age and shrink in volume, which is also a factor of water seepage between the plates. The utility model discloses, through the design to the middle thickness of bending 1 and first supporting part 21, second supporting part 22, make the pressure of upper and lower adjacent sound barrier cell board concentrate on the both sides position that is close the gap edge, the middle pressure that can not receive between the board of bending 1 basically. This allows greater pressure on both sides of the panel and the gap between the panels can be very tightly sealed by the panel structure 100.

The first side wing 31 extends from the first support portion 21 and is perpendicular or nearly perpendicular to the first support portion 21, and the first side wing 31 is attached to the outer surfaces of two adjacent sound

barrier unit panels

200 and 300. The first side wing portion 31 is attached to the two adjacent sound

barrier unit panels

200 and 300 by using the double-sided adhesive tape 4. The second side wing part 32 extends from the second supporting part and is perpendicular or nearly perpendicular to the second supporting part 22, and the second side wing part 32 is attached to the inner surface of the lower sound barrier unit panel 300 of the two adjacent sound barrier unit panels. The first side wing part 31 extends from the first supporting part 21 to the upper part and the lower part of each of two adjacent sound barrier unit plates by at least 15 mm; further ensuring that external rainwater, fog and the like can not enter gaps between the plates. The second wing part 32 extends at least 15mm from the second supporting part 22 to the inner surface of the lower sound barrier panel 300 of the two adjacent sound barrier panels. The second wing part 32 extends only toward the inner surface of the lower barrier cell plate 300, which is more advantageous for installation.
