JPS5936043B2 - Side wall structure of viaduct - Google Patents

Description

DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a side wall structure that prevents the vibrations of vehicles passing on a viaduct from being transmitted to the side wall, and in particular, when attaching the side wall to the viaduct, the side wall is attached to the end of the viaduct as in the past. This invention relates to a side wall structure in a viaduct, characterized in that an elastic body is interposed between the end of the viaduct and the side wall to connect and fix the two, without directly fixing them integrally.

Conventionally, side walls were attached to both ends of the viaduct to absorb the noise generated when trains and automobiles passed over the viaduct and to ensure safe travel, but the method commonly used in the past is shown in Figure 1. As shown in Fig. 2, the side wall B is integrally connected to the viaduct A, or as shown in Fig. 2, a method is used in which a column C is fixed to the viaduct A and then a side wall B is attached and fixed to the column C. In these conventional methods, the vibrations of vehicles running on the viaduct are directly transmitted from the viaduct to the side walls, so secondary sound is generated due to the resonance of the side walls, and the noise caused by the vehicles running is efficiently absorbed. Furthermore, the vibrations of the viaduct were transmitted directly to the bridge, causing cracks in the side walls and reducing its strength.

The present invention relates to a completely new technology that fundamentally improves the drawbacks of the conventional technology.

To explain the side wall structure of a viaduct according to the present invention with reference to figures, in FIGS. 3 and 4, A is a viaduct,
B is a side wall constructed by connecting panels 1 made of PC concrete plates, concrete blocks, etc. with supports 2.

Next, reference numeral 3 denotes an arm protruding from the side surface of the support column 2, which is designed to support the upper load and withstand lateral pressure and wind pressure caused by running vehicles.

Reference numeral 4 denotes an elastic body interposed between the lower surface of the arm 3 and the upper surface of the end of the viaduct A. When the load or pressure is large, the elastic body is extended long along the side wall, covered with a day-shaped material, and then the arm Install.

Therefore, in the side wall structure of the viaduct according to the present invention, the side wall is completely separated from the viaduct A, an arm 3 is provided protruding from the side surface of the side wall H, and an elastic body 4 having elasticity is provided on the lower surface of the arm 3. It is constructed by attaching the arm 3 to the end of the viaduct A with bolts 5, with the arm 3 interposed therebetween.

As the elastic body, a durable rubber, resin, or metal spring, plate spring, or the like can be used.

For the side wall mounting type 7, depending on the shape of the side wall, etc.
As shown in the figure, by bending the upper end of the side wall horizontally and using the frame 6, the side wall B is brought into contact with the viaduct A at two places, and the upper end of the side wall is bent horizontally.
As shown in the figure, the upper end of the side wall B is inclined and the contact area between the arm 3 and the viaduct A is widened, or the side wall of the viaduct A is made to stand vertically as shown in Fig. 7, and the side wall is attached to the upper end surface of the viaduct A. The arm 3 of B is joined together, or as shown in Fig. 8, the arm 3 is integrally protruded from the side surface of the side wall B by pouring concrete, and its lower surface and the end of the viaduct A are made wider and made of an elastic material. Various changes can be made as necessary, such as joining by intervening.

As described above, in the present invention, no matter what form the side wall takes, when the side wall B is attached to the end of the viaduct A, the elastic body 4 is interposed between the two, so that vibrations generated in the viaduct A can be transmitted to the side wall B. The aim is to prevent transmission as much as possible, and it goes without saying that various ways of connecting the viaduct A and the side wall B can be considered.

As described above, in the side wall structure of a viaduct according to the present invention, when the side wall is attached to the viaduct, the side wall is not directly fixed to the viaduct as in the conventional case, but a gope spring, a plate spring, etc. is installed between the end of the viaduct and the side wall. Since the elastic body is interposed, this elastic body stops the vibration and noise generated on the viaduct from being transmitted to the side wall of the viaduct, prevents the generation of secondary sound due to resonance of the side wall, and reduces the noise caused by running vehicles. The vibration can be efficiently absorbed by the side wall, and the vibration can be prevented from cracking in the side wall and reducing its strength due to repeated vibration.
