Description

TECHNICAL FIELD [0001] The present invention relates to a light interception device for a bridge bridge device,

BACKGROUND OF THE INVENTION 1. Field of the Invention [0001] The present invention relates to a light interception device for bridging bridge devices, and more particularly, to a light interception device for bridging bridge devices capable of preventing light from being exposed to various lights including sunlight, 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 (Sliding) function is a function that freely 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.

FIG. 2 is a perspective view showing a state in which the light shielding device for a bridge bridge device shown in FIG. 3 is a sectional view of the installation of the light interception device for bridge bridge devices shown in Fig. 2. Fig.

1 to 3, the light shielding device for a bridge bridge device includes a coaxial device 10 having an elastic layer 16 made of a rubber material between an upper plate 12 and a lower plate 14, An upper shielding member 30 which is installed on the coordinate system 10 so that the elastic layer 16 of the upper plate 12 is not exposed to light including sunlight and has an upper end coupled to the upper plate 12, And a fastening member 50 for connecting the upper shielding member 30 and the lower shielding member 40 to each other.

This will be described more specifically.

The coordinate system 10 according to the present invention includes an upper plate 12 installed on an upper structure of a bridge by a so-called elasticity quadrature apparatus, a lower plate 14 provided at a bridge pier, And an elastic layer 16 made of a rubber material provided between the upper plate 14 and the lower plate 14.

It goes without saying that the present invention can be applied to all teaching apparatuses 10 including a fixed type, a one-way acting type, and a bidirectional type.

The upper shielding member 30 is made of a thin plate-shaped plate having a size sufficient to cover at least 1/2 of the area of one surface of the coordinate system 10, and the upper end thereof is fixed to the upper plate 12 by a plurality of bolts. And one or more horizontal slots 32 are formed in the lower end region.

The lower shielding member 30 is formed of a plate material having a size equal to or larger than the size of the upper shielding member 30 and is provided with a vertical slot 42 at a position corresponding to the horizontal slot 32 of the upper shielding member 30. [ And the lower edge is coupled to one surface of the lower plate 14 by a plurality of bolts.

At this time, a vertical slot may be formed in the upper blocking member 30 and a horizontal slot may be formed in the lower blocking member 30. [

5, blocking blades 34 and 44 for extending the light shielding area to the side surface are formed at each side end of the upper shielding member 30 and the lower shielding member 40, respectively, . The lengths of the blocking blades 34M44 are formed to be long or short as necessary, that is, in consideration of the incident angle of light. By the blocking blades 34 and 44, the upper shielding member 30 and the lower shielding member 40 can extend to an area where they can not be blocked, thereby blocking light.

The upper shielding member 30 and the lower shielding member 40 may be made of a metal material to prevent the light including sunlight from shining on the elastic layer 16. However, the upper shielding member 30 and the lower shielding member 40 may be made of a synthetic resin material Lt; / RTI >

The fastening member 50 passes through the horizontal slot 32 of the upper blocking member 30 and the vertical slot 42 of the lower blocking member 40 so that the overlapping of the upper blocking member 30 and the lower blocking member 40 And in this embodiment, it may be composed of a bolt and a nut.

On the other hand, the fastening member 50 can be configured as shown in Fig. That is, the fastening member 50 includes a bearing member 52 provided so as to penetrate through the horizontal elongated hole 32 of the upper block member 30 and the vertical elongated hole 42 of the lower block member 40 which overlap with each other, And a nut 56 which is fastened to the fastening bolt 54 so that the bearing member 52 is positioned in the horizontal elongated hole 32 and the vertical elongated hole 42. [ . Since the bearing member 52 is provided so as to pass through the horizontal elongated hole 32 and the vertical elongated hole 42 in the fastening member 50 having such a structure, Movement can be smoothly performed within a range allowed by the horizontal slot 32 and the vertical slot 42. [ At this time, the bearing member 52 may be composed of an oil-less bearing or a ball bearing.

The operation of the light shielding device for a bridge bridge device according to the first embodiment of the present invention will be described. In this embodiment, the description will be made on the basis of blocking sunlight.

2 and 3, a calibration device 10 is installed in the bridge structure, and a direction of sunlight is grasped so that the upper surface of the upper block member 12 in the direction of sunlight And the lower end of the lower blocking member 40 is bolted to one surface of the lower plate 14. As shown in Fig. At this time, the horizontal slot 32 of the upper blocking member 30 and the vertical slots 42 of the lower blocking member 40 are adjusted to be aligned with each other.

The upper shielding member 30 and the lower shielding member 40 are connected to the upper plate 12 and the lower plate 12 by previously coupling the upper shielding member 30 and the lower shielding member 40 with the fastening member 50, 14).

Next, bolts are passed through the horizontal long holes 32 and the vertical long holes 42, which are aligned with each other, as fastening members 50, and then fastened with a nut. At this time, do not tighten the nut to the maximum. This is for the upper shielding member 30 and the lower shielding member 40 to freely move with respect to each other. More precisely, the upper plate 12 is allowed to move a predetermined distance or a vertical direction in the longitudinal direction of the horizontal slot 32 by the behavior of the coordinate system 10. [

3, when the fastening member 50 is fitted to the horizontal slot 32 and the vertical slot 42, sunlight is transmitted through the upper blocking member 30 and the lower blocking member 40, So that it can not reach the elastic layer 16. Therefore, the elastic layer 16 made of rubber by sunlight can be prevented from aging or corroding.

The upper shielding member 30 and the lower shielding member 40 may be horizontally elongated even if the upper plate 12 is moved by a predetermined distance or downward in one direction (50) that penetrates through the vertical slot (42) and the base member (32), so that it does not interfere with the behavior of the coordinate device (10) at all.

6 is a front view showing a second embodiment of the present invention, and Fig. 7 is a sectional view taken along line A-A of Fig.

6 and 7, the light shielding device for bridging bridge device according to the second embodiment is formed in a plate shape so as to prevent light including sunlight from reaching the elastic layer 12, An upper shielding member 30 coupled to the upper plate 12 and an upper shielding member 30 which is formed in a plate shape so as to prevent light including sunlight from reaching the elastic layer 12 and has a lower edge joined to the lower plate 14 An upper connecting plate 62 rotatably coupled to the lower end edge of the upper blocking member 30 by an upper longitudinal axis 61 and a lower connecting plate 62 whose lower end is connected to the lower blocking member 40 A lower connecting plate 64 rotatably coupled to the upper end edge and the lower longitudinal axis 63 and a lower connecting plate 64 rotatably coupled to the lower end of the lower connecting plate 64, (65) It is configured to include a bound material 60. At this time, a horizontal movement slot 38 is formed at the upper edge of the upper blocking member 30 to allow horizontal displacement of the co-ordinate apparatus 10, and the coupling bolt 38A is inserted through the horizontal movement slot 38 into the upper plate 12).

The upper shielding member 30 and the lower shielding member 40 are connected to each other by a folding and extending connecting member 60 and a horizontal moving hole 38 of the upper shielding member 30 So that the sunlight is prevented from shining on the elastic layer 16 and the vertical movement of the upper plate 12 due to the movement of the coordinate device 10 The longitudinal movement of the moving and horizontally moving slots 38 is permitted and does not interfere with the behavior of the calibration device 10. [

Particularly, since the upper shielding member 30 and the lower shielding member 40 are configured to be foldable like a hinge, even if the upper plate 12 moves in the direction of arrow A shown in FIG. 7, 30 and 40 do not interfere with the behavior of the upper plate 12. [ That is, the light interception device according to the present embodiment can be applied to the coordinate system 10 capable of bi-directional behavior.

8 is a cross-sectional view showing a third embodiment of the present invention.

The light shielding device according to the third embodiment as shown in FIG. 8 is formed of a stretchable plate material having an upper edge joined to the upper plate 12 and an upper stretchable portion 37 spirally bent at a lower end An upper shielding member 30 for blocking the light including sunlight from reaching the elastic layer 12, a lower shielding member 30 coupled to the lower plate 14 at its lower end and a spiral- And a lower blocking member 40 for blocking the light including sunlight from reaching the elastic layer 16, the lower blocking member 40 being formed of a stretchable plate material and having a lower elastic member 47 to be fitted in the longitudinal direction, .

Since the upper shielding member 30 and the lower shielding member 40 are connected to each other by the spiral upper stretchable portion 37 and the lower stretchable portion 47, The upwardly and downwardly stretchable portions 37 and 47, which are bent in a spiral shape during the directional behavior, are not interfered with the vertical movement of the upper plate 12, and in particular, the upper stretchable portion 37 and the lower stretchable portion 47 Are not interfered with the behavior in the longitudinal direction of the upper and lower stretchable portions 37 and 47. [ That is, even when the upper plate 12 moves in the longitudinal direction of the upper and lower stretchable portions 37 and 47, the upper stretchable portion 37 and the lower stretchable portion 47 are simply engaged with each other, So that the upper shielding member 30 moves with the upper plate 12 without any interference.

Further, in the case where the upper and lower blocking members 30 and 40 are made of a plate material having elasticity, the upper and lower blocking members 30 and 40 are elastically deformed even if the checking apparatus 10 moves in both directions, 10). &Lt; / RTI >

9 is a cross-sectional view showing a fourth embodiment of the present invention, and FIG. 10 is a partially enlarged cross-sectional view showing another embodiment of the elastic member shown in FIG.

9 and 10, the light shielding device according to the fourth embodiment has a top edge coupled to the top plate 12, and is formed of a plate material having a predetermined thickness, so that the elastic layer 16 includes sunlight An upper shielding member 30 for shielding light from reaching the lower plate 14 and a lower plate 14 connected to the lower plate 14 and formed of a plate material of a predetermined thickness so as to prevent light including sunlight from reaching the elastic layer 16 And the lower edge of the lower blocking member 40 is engaged with the upper edge of the lower blocking member 40 and the upper edge of the lower blocking member 40 is engaged with the lower edge of the upper blocking member 30, And a stretch connecting member 70 made of a rubber material or a synthetic resin material so as to be contracted or stretched.

At this time, the stretchable and contractible portion 74 may be formed to be thinner than the upper end region or the lower end region so that the stretchable and contractible member 70 can easily contract and expand.

10, a wrinkle portion 72 for allowing the movement of the upper shielding member 30 according to the behavior of the calibration apparatus 10 is formed at the middle portion of the stretching and connecting member 70 .

The stretchable portion 74 and the wrinkle portion 72 described above are easily deformed or deformed when the upper plate 12 moves in both directions (front, rear left, and right) and in the vertical direction due to the behavior of the coordinate system 10 So as to maintain the connection state of the upper and lower blocking members 30 and 40 while preventing the interference with the behavior of the coordinate system 10. [

The upper shielding member 30 and the lower shielding member 40 are connected to each other by the elastic member 70 made of a rubber material or a synthetic resin capable of being shrunk and stretchable to prevent sunlight from reaching the elastic layer 16 But also the bidirectional behavior and the behavior in the vertical direction of the coordinate system 10 are not interfered at all.

11 and 12 are sectional views showing a fifth embodiment of the present invention.

11 and 12, the light shielding device for a bridge bridge device according to the fifth embodiment has an upper edge coupled to the upper plate 12 and at least one horizontal slot 110 formed at a lower end thereof A light shielding member 100 for shielding light including sunlight from reaching the elastic layer 16 and a light shielding member 100 penetrating through a horizontal slot 110 formed in a lower end of the light shielding member 100, And a fastening member 50 formed of a bolt for movably coupling the lower end of the light blocking member 100 to the lower plate 14.

That is, the light shielding member 100 is integrally formed by a fastening member 50 whose upper end is bolted to the upper plate 120 and whose lower end is fastened to the lower plate 14 through the horizontal elongated hole 110 And is configured to be movably coupled to the lower plate 14.

At both ends of the light blocking member 100, a side blocking portion 120 for blocking light entering the side surface of the elastic layer 16 (direction in which the light blocking member can not be blocked) is bent. Such a structure is for effectively shielding sunlight incident in the morning, noon, afternoon, and the like. The length and the length are not limited to the length and the size shown in the drawing, but can be variously formed according to the construction site.

The light shielding member 100 is formed with a bent portion 130 bent in the horizontal direction (lengthwise direction of the light shielding member) to be deformed so as to absorb the amount of displacement of the elastic layer 16 in the vertical direction. Although the bending portion 130 is formed as one bending portion in the drawing, the bending portion 130 may be formed of a plurality of bending portions. 11 and 12, the bent portion 130 has a function of guiding and discharging foreign matter, rainwater, and the like directly into the lower plate 14 without flowing into the lower plate 14. As shown in FIGS.

Since the light shielding member 100 is integrally formed as described above, the structure is simplified, but it is possible to flexibly cope with the function of blocking light or the interference of the displacement of the bridge coaster apparatus 10. [

As described above, since various types of light shielding devices as described above are installed on one side or various sides of the coordinate measuring device 10, the elastic layer 16 of the calibration device 10 is exposed to the sunlight or the like, Thereby preventing a phenomenon of aging or aging.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It is obvious to those who have. Accordingly, it should be understood that such modifications or alterations should not be understood individually from the technical spirit and viewpoint of the present invention, and that modified embodiments fall within the scope of the claims of the present invention.
