The present invention relates to a structure support device, and more particularly, to a structure support device for stably supporting an upper structure such as a top plate of a bridge on a support structure such as a bridge pier.

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 appropriately mounted on the supporting structure, such as the pier supporting it. However, there are various forms and functions depending on the supporting load.

Some of the structure support devices are installed on the fixed end of the bridge to elastically support only the load in the vertical direction of the upper structure and do not allow the upper structure to move in the horizontal direction. The upper structure is moved to the horizontal direction to some extent in order to allow thermal expansion or thermal contraction of the upper structure to be installed and supported, and to buffer the force acting in the horizontal direction according to wind pressure, traveling, stopping, or earthquake of a vehicle or train. Some are allowed. The structure supporting device is provided with a shock absorber in the horizontal direction.

In this regard, there is disclosed in the registration publication of Utility Model Registration No. 0262491, "Study device having a large vertical buffering force" (hereinafter referred to as the invention of the invention) registered and developed by the inventor of the present application, see FIG. The description is as follows.

1 is a cross-sectional view showing an example of a structure support apparatus according to the invention of the prior application, Figure 2 is a view showing the installation state of the structure support apparatus.

As shown in the figure, the structure supporting apparatus 100 includes a lower plate 110 fixed to the pier 10 and an upper plate 130 installed on the bottom surface of the upper structure 20 supported by the pier 10. The pinhole 112 is formed near the center of the lower plate 110. Between the lower plate 110 and the upper plate 130, the intermediate member 160 is provided with a buffer disk 150 and a pin 162 inserted into the pin hole 112 in the center of the bottom surface.

The intermediate member 162 is supported by the buffer disk 150 and can be moved in the up and down direction and the direction inclined in any direction, but the movement in the horizontal direction by the pin 162 and the pin hole 112 Subject to this limitation. The upper surface of the intermediate member 160 is provided with a fluororesin plate 164 for reducing friction, and a stainless steel plate 132 is attached to the bottom of the upper plate 130 facing the same.

As shown in the upper plate 130, the support plate 180 is installed on both sides at intervals from the intermediate member 160, the horizontal elastic body 190 is bolt 192 and the nut 194 on the support plate 180 ) Is installed. The horizontal elastic body 190 is interposed between the intermediate member 160 and the support plate 180 between the intermediate member 160 and the support plate 180 when the upper plate 130 installed in the upper structure is moved in the horizontal direction. Compression serves to buffer the horizontal impact force acting between the piers and the upper structure 20. In addition, the fluororesin plate 196 and the stainless steel plate 166 are respectively attached to the corresponding surfaces for smooth sliding between the horizontal elastic body 190 and the intermediate member 160.

The structure supporting apparatus 100 is installed on the bridge 10 of the bridge 30 as shown in Figure 2 to support the upper structure 20 through the girder 22, etc., of the upper structure 20 While supporting the load in the up and down direction, it receives the normal load in the horizontal direction of the upper structure 20 in normal times, and also serves to cushion the large impact force in the horizontal direction of the upper structure due to the earthquake during an earthquake.

The structure supporting apparatus 100 as shown in FIG. 1 is capable of absorbing the horizontal shocks in the four directions when the horizontal elastic body 190 is installed in all four directions, while the bridges are subjected to the large impacts in the vertical direction by the buffer disk. It can stably protect the structure of the structure, it is excellent in versatility, it is also suitable for maintenance, and the rapid transverse impact force such as earthquake can be dealt with quickly through the shock absorbing member. Since the compressive stiffness can vary, there are many advantages such as easy design according to the amount of impact, but there is a need for improvement in the following points.

First, as the horizontal elastic body 190 is installed between the intermediate member 160 and the support plate 180, the distance between the intermediate member 160 and the support plate 180 is at least horizontally allowed to move the upper member 130. The distance and the length when the horizontal elastic body 190 is contracted to the maximum should be more than the distance. Accordingly, in the structure support apparatus 100 in which the horizontal elastic body 190 is installed at both sides of the intermediate member 160, the length or width of the upper plate 130 on which the support plate 180 is installed is very large.

For example, in a long bridge where the length of the superstructure is hundreds of meters or more, the usual amount of expansion due to thermal contraction or thermal expansion or the like may be ± 20 cm, and the amount of expansion during an earthquake may be about ± 10 cm. In this case, the length of the horizontal elastic body 190 is very long because it has to consider both its length and the expected amount of expansion and contraction during an earthquake. When the horizontal elastic body 190 is long, the upper plate 130 becomes too large considering that the horizontal elastic body 190 is installed at both sides.

If the top plate 130 is too large, a situation in which the top plate 130 protrudes to the side of the girder 22 of the upper structure 20 as shown in Fig. 2, the structure supporting device as shown in Fig. 100) is difficult to be used for long bridges, despite its excellent performance.

In addition, if the size of the structure support device 100 increases, it is disadvantageous in terms of cost, movement, storage, installation work, and economic efficiency.

When the horizontal elastic body 190 contracts under pressure, the center portion of the horizontal elastic body 190 is convexly deformed, as shown by the dotted line. Therefore, the distance between the horizontal elastic body 190 and the upper plate 130 should be considered. This should be sufficiently maintained, and thus the height of the intermediate member 160 and the support plate 180 should also be large.

In the state where the horizontal elastic body 190 is installed between the intermediate member 160 and the support plate 180, the horizontal elastic body 190 may be detached from the horizontal elastic body 190 after the bolt 192 is separated from the horizontal elastic body 190. The replacement of 190 is rather tricky.

3 is a cross-sectional view showing an example of a structure supporting apparatus according to the present invention.

As shown, the structure supporting apparatus 200 according to the present invention is installed between the supporting structure 30 and the upper structure 40 supported thereon, while supporting the load of the upper structure while supporting the horizontal structure between the supporting structure and the upper structure. To use to buffer the force acting as, the lower member 210 is provided. The lower member 210 is fixedly installed on the supporting structure 30 such as a bridge pier or a foundation of a building, and may be installed to the foundation nut 32 through a bolt 212. In some cases, the lower member 210 may be fixed by welding or other methods. The lower member 210 is provided with a pin hole 214 formed in the center portion. When the present invention is applied to the structure supporting apparatus 200 of another type, the pin hole 214 may not be formed. This can be seen with reference to the embodiments described below. The lower member 210 is generally formed in a plate shape, but may be made in a non-plate shape, such as a block, depending on the surrounding conditions, uses, or types.

The structure supporting apparatus 200 according to the present invention includes an upper member 220. The upper member 220 is installed on the bottom of the upper structure 40 supported by the support structure 30, and is fixed to the bottom of the upper structure 40 through welding or bolts and nuts. A stainless steel plate 222 is attached to the bottom of the upper member 220.

An intermediate member 230 is installed at the bottom of the upper member 220. The fluorine resin plate 232 is attached to the upper surface of the intermediate member 230. The fluorine resin plate 232 is to reduce the friction with the stainless steel plate 222, and may be of a different material such as PFT plate. PTF is a plate using Poly Tetra Fluoro Ethylene (PTFE) coating, which is a milky white flexible resin coated plate.

This may be similarly used for the stainless steel plate 222 of another similar material. If the frictional force between the two members in contact is small, it can be replaced with another material.

Depending on whether the structure supporting device 200 is to be used for the bidirectional movable end of the structure such as a bridge or the one-way movable end, the intermediate member 230 permits the sliding motion with respect to the upper member 220 in both horizontal directions, front and rear, left and right. Or, it is made to allow the sliding movement with respect to the upper member 220 only in one horizontal direction of the front and rear or left and right. That is, the intermediate member 230 allows the sliding movement in at least one horizontal direction with respect to the upper member 220.

In addition, the intermediate member 230 is limited to movement in at least one horizontal direction with respect to the lower member (210). That is, the intermediate member 230 is made to be limited to movement in both the horizontal direction of the front and rear or left and right with respect to the lower member 210 or the movement in only one horizontal direction.

The pin 234 is provided at the center of the bottom surface of the intermediate member 230. The pin 234 is usually made of high strength metal to withstand large shear and bending forces.

The vertical elastic body 240 is installed between the intermediate member 230 and the lower member 210. The vertical elastic body 240 serves to elastically support the load in the vertical direction of the upper structure 40. The outer circumferential surface of the vertical elastic body 240 is formed with a concave groove so as to be rotated and tilted to either side when a force deflected from the center is applied, and penetrates the pin 234 through the center portion thereof. The hole 242 is formed. The vertical elastic body 240 is a disk made of polyurethane (Polyurethane) is suitable. The pin hole 214 described above is formed slightly larger than the outer diameter of the pin 234 to allow rotation when the upper structure receives the rotation moment in the state in which the pin 234 is inserted.

The intermediate member 230 is usually made in a quadrangular shape having four sides. The fixing member 250, the first horizontal elastic support 260, the shaft member 270, and the hollow first horizontal elastic body 280, which will be described later, may be installed on all four sides of the front, rear, left, and right sides, It may be installed only on both sides of the side or both sides before and after.

As shown in the bottom of the upper member 220, the fixing member 250 is installed to protrude downward. The fixing member 250 is disposed at both sides of the intermediate member 230 at intervals from the intermediate member 230. The fixing member 250 is for allowing the first horizontal elastic body 280 to be described later to be installed horizontally. Since the first horizontal elastic body 280 is installed on the outer side of the fixing member 250, there is no need for a space for the first horizontal elastic body 280 between the fixing member 250 and the intermediate member 230, and thus, the fixing member The distance between the 250 and the intermediate member 230 may be about the horizontal moving distance of the upper member determined by the structure design.

That is, in the structure supporting apparatus 200 according to the present invention, the distance between the fixing member 250 and the intermediate member 230 can be significantly reduced, compared to the conventional one, and accordingly, the length or width of the upper member 220 is greatly reduced. Can be.

In the conventional structure support apparatus 100, when the horizontal elastic body 190 is compressed, the middle portion thereof bulges convexly so that the horizontal elastic body 190 is moved downward to avoid interference with the upper member 130 during compression. It should be installed at a sufficient distance from the bottom of the upper member 130, in this case there is a disadvantage that the height of the intermediate member 160 is also relatively large, in the present invention, the first horizontal elastic member 280 is the upper member 220 Since there is no fear of interference with the height of the intermediate member 230 can be made smaller than the conventional one.

The fixing member 250 is formed with a first through portion 252 facing outward from the side of the intermediate member 230.

The fixing member 250 as described above only needs to be installed in a direction that requires a buffer in the horizontal direction of the upper structure 40. That is, the fixing member 250 may be installed only on both the left and right sides of the intermediate member 230, or may be installed on both sides of the front and rear sides, and may be installed on both the left and right sides and both sides of the front and rear sides as necessary.

The first horizontal elastic support 260 is provided horizontally on the outer surface of the fixing member 250, respectively. The first horizontal elastic support 260 is an outer support end 262 for supporting the outer end of the first horizontal elastic body 280, the connection for supporting the outer support end 262 to the side of the fixing member 250 Member 264. In some cases, the inner side of the end of the connecting member 264 may be blocked by the base member 266 in which a hole for passing the shaft member 270 is formed. The outer support end 262 has a second through portion 264a which faces the outer surface of the fixing member 250 at intervals and is formed at the center thereof. The base member 266 mentioned above is for easily installing the first horizontal elastic support 260 to the fixing member 250 and stably supporting the shaft member 270, and is not necessary. It is preferable to form a bolt hole in the base member 266 to be detachable to the outer surface of the fixing member 250 using the bolt 268.

The outer support end 262 may also be detachable using the bolt 269, and in some cases, the outer support end 262 may be integrally formed with the connection member 264.

The structure supporting apparatus 200 according to the present invention includes a shaft member 270. The shaft member 270 not only horizontally supports the first horizontal elastic body 280, but also transmits or applies a horizontal force acting between the intermediate member 230 and the upper member 220 to the first horizontal elastic body 280. It serves to transfer the restoring force of the one horizontal elastic body 280 to the intermediate member 230 and the upper member 220. The shaft member 270 is horizontally installed through the second through portion 264a and the first through portion 252 so that the inner end thereof is supported by the side surface of the intermediate member 230. The outer side end of the shaft member 270 exits to the outside of the outer support end 262 through the second through portion 264a of the outer support end 262. A first spiral 272 is formed at an outer end of the shaft member 270, and a first nut 274 is fastened to the first spiral 272. When the first nut 274 is used, the first horizontal elastic body 280 can be easily compressed as much as desired, and the initial compression force can be easily adjusted. In some cases, the first nut 274 may be omitted, but the initial compression force is difficult to adjust. Of course, when the first inner support end 276 and the second inner support end 277 described later are fastened in a spiral manner, the initial compression force may be adjusted by adjusting them.

In addition, in some cases, when the outer support end 262 is formed thick, the outer end of the shaft member 270 may be inserted into the second through portion 264a. A first inner support end 276 for supporting an inner end of the first horizontal elastic body 280 is formed on one outer peripheral surface of the shaft member 270. The first inner support end 276 may be fixed, but a second helix 278 is formed on the outer circumferential surface of the shaft member 270, and a second nut 276a coupled to the second helix 278 is formed. It can form using.

A second inner support end 277 is provided at the inner end of the shaft member 270. The second inner support end 277 is for stable contact with the intermediate member 230, the fluorine resin plate (277a) is attached to the inside, and the stainless steel plate (2) on the side of the corresponding intermediate member (230) 236 is attached.

As shown in the drawing, the first horizontal elastic body 280 is installed inside the first horizontal elastic support 260. The first horizontal elastic body 280 is coupled to the outer circumferential surface of the shaft member 270 between the outer support end 262 and the first inner support end 276, the outer end of which is supported by the outer support end 262. The inner end is supported by the first inner support end 276 installed on the shaft member 270. The first horizontal elastic body 280 is a hollow one that can be coupled to the shaft member 270 is used. As the first horizontal elastic body 280, a cylindrical mass spring (Mass Energy Regulator Spring) made of polyurethane is suitable. It has a compression coefficient more than 16 times larger than rubber and can withstand hundreds of thousands of high-speed shocks, and it can tolerate shrinkage displacement up to 30% of its total length when constant displacement is applied, and up to 60% displacement during an earthquake. Can be allowed. Two to eight of the first horizontal elastic bodies 280 are mounted on both sides or in all directions. In some cases, three or more may be installed on one surface.

In addition, as shown in FIG. 3, the first horizontal elastic body 280 is provided outside the fixing member 250 on both front and rear sides along the axial direction of the bridge, and the horizontal elastic body is shown in FIG. 1 in the perpendicular direction of the axial axis. The fixing member 250 may be provided inside the fixing member 250. On the contrary, the first horizontal elastic body 280 may be installed outside the fixing member 250 in the axial direction perpendicular to the fixing member 250. The present invention can be configured by installing a horizontal elastic body on the inner surface of the member 250.

The first horizontal elastic support 260, the shaft member 270, and the first horizontal elastic body 280 described above are combined with each other to form one elastic mechanism 300. The elastic mechanism 300 is made of a part of the structure supporting device 200 can be distributed separately. This is described in more detail later.

In the state as shown in FIG. 3, when an earthquake occurs and a horizontal force is applied to the right side of the intermediate member 230, the right shaft member 270 is moved to the right side because the right shaft member 270 is supported by the intermediate member 230. Accordingly, the first inner support end 276 fixed to the outer circumferential surface of the shaft member 270 is also moved to the right to press the first horizontal elastic body 280, and the first horizontal elastic body 280 contracts its left and right lengths. It cushions the impact force. When the first horizontal elastic body 280 is compressed and then expanded again, the first horizontal elastic body 280 exerts a restoring force on the first inner support end 276.

That is, the first inner support end 276 is moved together with the shaft member 270 as the shaft member 270 is moved horizontally outward to press the first horizontal elastic body 280 to the outer support end 262. The first flat elastic body 280 is compressed, and then receives a restoring force inward from the first flat elastic body 280 that is compressed.

4 is a cross-sectional view showing a modified example of the structure supporting apparatus of FIG.

In some cases, the shaft member 270a may be one having a bolt head formed at an outer end thereof. In this case, the initial compression may adjust the initial compression force of the first horizontal elastic body 280 by tightening or loosening the second nut 276a forming the first inner support end 276.

In addition, the first horizontal elastic support 260a may be configured in a form in which a lower portion thereof is opened without a base member.

The rest is the same as described above with reference to FIG.

5 is a cross-sectional view showing another example of the structure supporting apparatus according to the present invention.

In some cases, a second inner support end 277 is formed at an inner end of the shaft member 270, and an outer circumferential surface of the shaft member 270 between the second inner support end 277 and the fixing member 250 is provided. The hollow second horizontal elastic body 290 can be further installed in the. When the spirals are formed by forming spirals at the ends of the second inner support end 277 and the shaft member 270, respectively, the initial compressive force of the second horizontal elastic body 290 may be adjusted.

As shown in FIG. 5, when both the first horizontal elastic body 280 and the second horizontal elastic body 290 are installed, a large bearing force in the horizontal direction can be obtained.
