HORIZONTAL LOAD BUMPER ASSEMBLY AND STRUCTURE SUPPORTING APPARATUS WITH THE SAME}

The present invention relates to a structural support device, such as a bridge device, and in particular, by the division structure bounded in the middle of the body of the elastic material by dispersing and minimizing the degree of swelling in the vertical direction even when the horizontal load is largely acted with other components The present invention relates to a horizontal load absorbing assembly and a structure supporting device having the same, which are easy to grasp, and modular, because of preventing linear interference and performing predictable linear behavior at all times.

In general, the structure supporting device is a device installed between the supporting structure and the upper structure so that the upper structure such as the upper plate, which is the slab structure of the bridge, is properly mounted on the supporting structure such as the pier supporting the same. Various types are used depending on the size of the lamp, the load, and the type of the structure.

Recently, a structure supporting apparatus having a horizontal load absorbing assembly is widely used among the structural supporting apparatuses. FIG. 1 is an exploded perspective view for explaining a structure supporting apparatus having a horizontal load absorbing assembly according to the prior art, and FIG. Reference cross section for explaining a horizontal load absorbing assembly by the technique.

As shown, the structure supporting apparatus according to the prior art is coupled to an upper structure such as a bridge top plate and sidewalls along the circumference so that the horizontal force may be separated from the upper structure and the lower structure in any direction during earthquake. An upper plate 10 having an outer support portion 10a formed in a shape, a lower plate 20 and an anchor 50 coupled to a lower structure such as a pier, and between the upper plate 10 and the lower plate 20. A horizontal load buffer assembly that ensures structural stability by resisting the horizontal load acting during an earthquake with rigidity by appropriate compression deformation, with the disk bearing assembly including the intermediate support member 30 and the disk 40 installed in the matrix as a mother. 60 is included in the state surrounded by the outer support (10a) of the upper plate (10).

Here, the horizontal load buffer assembly 60, the horizontal elastic body 62 is formed with a guide hole in the longitudinal direction, and a guide rod inserted into the guide hole of the horizontal elastic body 62 to allow expansion and contraction of the horizontal elastic body 62 ( 61 and a support 64 coupled to one end of the guide rod 61 to support one surface of the horizontal elastic body 62 in the stretch direction.

The horizontal load buffer assembly 60 having such a configuration has an outer support portion 10a and an intermediate support member of the upper plate 10 in the initial state shown in FIG. 2A when the horizontal load occurs due to an earthquake. The horizontal elastic body 62 installed between the layers 30 was compressed and deformed to secure the structural stability by resisting the horizontal load. 2 (b) shows a state in which the horizontal elastic body 62 is compression-deformed between the outer support portion 10a and the intermediate support member 30 of the upper plate 10 so that the middle portion S is excessively inflated. Giving.

However, in the structure supporting apparatus according to the related art, when a strong horizontal load is generated due to an earthquake, compression deformation of the horizontal elastic body 62 concentrates on a specific part (mainly an intermediate part) as shown in FIG. The horizontal elastic body 62 is pressed against the upper plate 10 and the lower plate 20 due to excessive swelling. This not only causes damage to the horizontal elastic body 62 but also causes a fatal problem that is very difficult to determine the correct design value due to the linear behavior of the horizontal elastic body 62.

On the other hand, in order to eliminate the interference between the horizontal elastic body 62 and other components and to secure the linear behavior of the horizontal elastic body 62, a space between the upper plate 10 and the lower plate 20 should be secured with an upper structure.

The flat plate 150b is attached. This allows smooth horizontal movement while preventing damage to components.

The horizontal load buffer assembly 100 configured as described above has various advantages due to the divided structure in which the horizontal elastic body 110 is divided into a plurality of units 110a, 110b, and 110c.

That is, even if the horizontal load acts largely due to an earthquake or the like, instead of concentrating the bulging in the vertical direction in one place, the components are distributed and minimized evenly by the units 110a, 110b, and 110c, and other components, in particular, the upper plate 10 ) And the lower plate 20 are prevented. As a result, the swollen form is not damaged and always has a predictable linear behavior. This has the advantage that the characterization and design of the product is considerably easier.

In addition, the horizontal load buffer assembly 100 can be modularized by the divided structure divided into units (110a, 110b, 110c) around the boundary surface 130, and the installation and maintenance is convenient.
