Description
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a light shielding device for bridging bridge devices, and more particularly, to a light shielding device for bridging bridge devices, The present invention relates to a light shielding device for a bridge bridge device capable of preventing aging phenomenon.
The bridge is designed to transmit the load of the upper structure to the lower structure. The bridge should function faithfully for displacement and deformation such as expansion and contraction of the upper structure due to temperature change or elastic deformation, and also for seismic force, wind load and lateral load The working load must be transferred to the substructure in a stable manner.
The function of such a query device has a supporting function, a rolling function, and a slip function.
The supporting function is a function to support the charge of the upper structure in the same manner as the reaction force in the main sphere of the lower structure and the rolling function is a function of rotating the bridge end caused by the self weight of the upper structure and the external load The sliding function is a function that freely permits expansion and contraction due to slippage caused by expansion and contraction caused by temperature, drying shrinkage, braking force, and the like without causing any restraining force.
This type of bridge is divided into movable type and fixed type according to function and role, and movable type and fixed type are again classified into a steel coining device and a rubber coining device. Such a coining device is most closely related to bridge safety and life span It requires proper maintenance.
Among the above-described coordinate measuring apparatuses, the rubber measuring apparatus is a so-called elastic measuring apparatus in which one or more steel plates are reinforced in the rubber layer to increase the load-bearing capacity. The elastic measuring apparatus is effective in supporting function within the elastic deformation without frictional force, It is possible to make arbitrary shape, and it is easy to construct and economical. Instead, rubber material is oxidized to lose elasticity, and phase lift or buoyant force There is a disadvantage that it can not be suppressed.
Particularly, the rubber layer is exposed to sunlight, which is oxidized or aged by light, resulting in cracking of the surface and loss of elasticity.
As a means for solving such a problem, Korean Patent Registration No. 10-493515 (Published on Jun. 10, 2005) discloses a box structure for protecting a bridge apparatus for a bridge, and Korean Patent Registration No. 10-1034281 . 16) discloses a protective device for preventing the performance of the calibration device from deteriorating. Such prior art techniques have been able to substantially prevent contamination and corrosion due to algae excrement as well as corrosion by natural environments by covering the entire survey device in a sealed state.
However, such prior art teaching apparatus protecting means does not take into consideration that the teaching apparatus is operated by displacement, deformation, seismic force, wind load and lateral load of the upper structure such as expansion and contraction of the upper structure, There is a problem that the means is not absorbed so that the protective means is broken, the bonding portion is broken, or the gap is generated.
