Description

Coupling Structure for bridge

The present invention relates to a structure in which bridges are flexibly connected to each other, and more particularly, to a bridge connecting structure in which loads to spaces between bridges are more securely supported, and all problems caused by foreign matters are solved.

Bridges placed on the upper part of the bridge naturally extend or shorten in the axial direction due to the temperature difference according to the seasonal change, and the length in the axial direction is forcibly extended by external forces such as load and wind applied to the bridge. As it is either reduced or reduced, a distance between the ends of the bridges which are opposed to each other should be provided for the change of length in the direction of the bridge.

When the bridges extend in the direction of the bridge and the ends of the bridges are close to each other, the vehicle can travel smoothly on the bridge connection, but the bridge is reduced in the direction of the bridge, so that the separation distance between the bridges of the bridges is extended. In this case, the wheel of the vehicle interferes with the bridge connection part, and the ride comfort is greatly reduced. Furthermore, if the extension length in the bridge direction is greater than this (the longer the bridge length is in the bridge direction, the larger the extension length is). As the separation distance between them becomes larger, a serious problem arises that the wheels of the vehicle fall completely into the bridge connecting portion.

Therefore, a separate bridge connecting mechanism should be provided at the tip of the bridge so that the loads to the spaces between the mutually opposing bridges are supported by the bridge connecting mechanism.

The bridge connecting structure for supporting the loads to the spaces between the bridges while flexibly connecting the bridges has already been proposed and widely used, and the rail type bridge connecting structure using the rail as the bridge connecting mechanism, and the finger block bridge The finger block type bridge connecting structure used as a connecting mechanism is representative.

In the rail bridge connecting structure, as shown in FIG. 1, a pair of chambers 11, which are open to the front end side of the front end reinforcement part C2 of the bridges BG; At least one moving support 13 is sequentially disposed in the orthogonal direction in the axial direction, and both ends of each moving support 13 are respectively inserted into openings of the chamber 11 facing each other to guide the block 12. It is fixed to these chambers (11) through a medium, and at least one rail 15 is movably mounted on the upper surface of the movable support 13, the rail 15 to each movable support 13 While being fixed individually, a pair of front end blocks 14 are installed on the upper end of the front end reinforcement part C2 of the mutually opposed bridges BG; BG ', and the front end block 14 and the rail are opposed to each other. (15) or rails 15 and 15 are made of synthetic rubber or resin It forms a structure that is interconnected via one connecting member (16).

When the bridge BG; BG 'is extended, the guide block 12 slides around the moving support 13, and the bridges BG BG' are close to each other, so that the separation distance L between them is reduced and moved. The rails 15 fixed to the support 13 are correspondingly close to each other so that the rail connecting member 16 is folded. On the other hand, when the bridge BG; BG 'is reduced, the operation between the components proceeds in the inverse of the operation, so that the separation distance L of the bridge BG; BG' is increased, and the rails 15 The separation distance is also increased. On the other hand, the front end block 14 and the rail 15, the rail 15 and the rail 15 are closely connected to each other via the rail connecting member 16, the foreign matter such as rain water or dust bridge (BG; It does not penetrate into the spaces between BG ').

Although the rail-type bridge connecting structure can be said to have a large number of components, and it can be said that the mutual assembly work between the members is cumbersome, the manufacturing of these components is easy and inexpensive, so it is still widely used. It is used.

However, in this rail type bridge connecting structure, the rails 15 are arranged in a direction perpendicular to the bridge axis, that is, in the width direction of the bridge BG; Since the interference with the vehicle wheels is severely generated, there is a disadvantage in that the ride comfort of the vehicle is lowered, and joints are greatly generated due to mutual interference.

In order to solve the shortcomings of the rail type bridge connection structure, a finger block type bridge connection structure has been proposed, which will be described in more detail with reference to FIGS. 2A to 2B.

2A and 2B, in the conventional finger block type bridge connection structure, the base panel 5 is respectively seated on the upper surface of the tip reinforcement portion C2 of the bridge BG; Blocks 20 and 20 'are placed on the base panel 5 so as to be opposed to each other and interlock with each other, and the base panel 5 and the finger blocks 20 and 20' are provided through fixing members F1 such as anchors. ) Is fixed to the tip reinforcement portion C2 of the bridge (BG; BG '), while both ends of the drip panel 400 are butted to each other via a fixing member F2 such as an anchor (BG; BG). It forms a structure that is respectively fastened to the end surface of the reinforcement portion (C2) of the '). As shown in FIG. 2B, the finger blocks 20 and 20 'protrude from the main body portion 21 in which the fastening holes 21a are formed, with the finger portions 22 at equal intervals, and the finger portion 22. A finger insertion groove (H1) is formed between the) forms a structure.

When the separation distance L between the bridges BG and BG 'approaches, the finger block 22 of the finger block 20 installed on one bridge BG is provided on the other bridge BG'. Finger block 20 installed in the other bridge BG 'in the finger insertion groove H1 of the finger block 20 installed in one bridge BG while being inserted into the finger insertion groove H1 of 20'. ') Is inserted into the finger 22, a pair of finger blocks (20; 20') are engaged with each other like a pod with two hands. On the other hand, when the separation distance (L) between the bridge (BG; BG ') is far apart, a pair of finger blocks (20; 20') installed therein are separated from each other, a pair of finger blocks (20; 20 ') ), The fingers 22 of these finger blocks 20; 20 'are arranged side by side to face each other in the direction perpendicular to the axial direction, and support the load to the space between the bridges BG; BG'. Done. When the vehicle travels through the connecting portion of the bridge BG (BG '), the vehicle wheel passes through the pair of finger blocks 20 and 20', and the finger parts 22 thereof protrude in the bridge direction of the bridge. In addition, since its finger insertion groove (H1) also protrudes in the bridge's axial direction, the vehicle wheel naturally passes over these finger blocks (20; 20 '), to prevent the deterioration of ride comfort, and to generate joints due to interference. This is greatly reduced. On the other hand, foreign matters such as rainwater, dust, gravel, etc. are introduced into the drip tray panel 400 through the finger insertion groove H1 of the finger blocks 20 and 20 ', and then both sides of the bridge along the drip panel 400. Since it moves in the direction, it is possible to prevent the introduction of foreign substances into the spaced space between the bridges (BG; BG ').

3A and 3B are cross-sectional views showing another example of the finger block type bridge connection structure according to the related art, in which the finger blocks 30 and 30 'are connected via the fixing member F1 to the bridge BG; BG ') is directly fastened to the tip reinforcement portion (C2), both ends of the corrugated pipe 600 for the drip tray is fixed to the finger block (30; 30'), which are disposed to face each other via the corrugated pipe fixing member (7) It becomes a structure.

However, the finger block type bridge connection structure according to the prior art has a structure in which the finger parts 22 and 32 of the finger blocks 20 and 20 'and 30 and 30' are not supported anywhere, so that the finger parts 22 32, a significant moment is generated in the finger blocks 20, 20 '; 30, 30'. Accordingly, the joint portion of the main body portions 21 and 31 and the fixing member F1 of the finger blocks 20, 20 'and 30 and 30', or the tip reinforcement of the fixing member F1 and the bridges BG and BG '. Since the stress is concentrated in the engaging portion with the part (C2), there is a problem that its breakage is caused.

In addition, since foreign matters such as rainwater, dust, and gravel are directly introduced into the drip member 400 (600) through the finger insertion grooves H1 of the finger blocks 20, 20 '; 30, 30', Frequently, foreign substances having a large volume and self weight are introduced into the drip member 400; 600. When foreign substances having a large volume and self weight are introduced into the drip member 400; Since the foreign matters are quickly loaded, the drip member 400 (600) is damaged by the weight of the foreign matters, or the expansion of the bridge (BG; BG ') caused by the foreign matters occurred.

Therefore, the present invention has been invented to solve the above problems, and an object of the present invention is to provide a bridge connecting structure in which loads to spaces between bridges are more safely supported, and all problems caused by foreign matters are solved.

It is mounted on and supported on the base panel of the beam bridge, and the free end of the finger part is supported on the first reinforcement panel so as to be movable. It has a structure that.

Hereinafter, the present invention will be described in detail with reference to the accompanying drawings.

4A to 6B, in the bridge connecting structure according to the present invention, the base panels 100 are respectively mounted on the upper surfaces of the tip reinforcement portions C2 of the bridges BG; A pair of finger blocks (200; 200 ') which are disposed to face each other and interlock with each other is placed on the (100), and the base panel (100) and the finger blocks (200; 200') are connected to each other through the fixing member (F1). Tip reinforcement of the bridge (BG; BG '), which is fixed to the tip reinforcement (C2) of the bridge (BG; BG'), while both ends of the drip member (400,600) are butted to each other via the fixing member (F2) (C2) or the panel guide grooves H2 which are fastened to the base panel 100, respectively, and communicate with the finger insertion groove H1 between the finger portion 212 and the base panel 100 of the finger blocks 200; And a first reinforcing panel 300 is inserted into the panel guide groove H2, so that both ends of the first reinforcing panel 300 face each other, and the base panel 10 of the bridge BG; It is mounted on and supported by 0), and the free end of the finger portion 212 is movable to the first reinforcement panel 300 to form a structure.

According to the present invention, the fixed ends 211 and 220 of the finger blocks 200 and 200 'are firmly fixed to the bridges BG and BG' through the fixing member F1, and the finger blocks 200 and 200 'of the finger blocks 200 and 200' are fixed. Since the free end (finger portion 212) is movably mounted on the first reinforcement panel 300, the load applied to the finger blocks 200 (200 ') is evenly supported through both distal ends. Therefore, a coupling portion between the fixed ends 211 and 220 of the finger blocks 200 and 200 'and the fixing member F1, or a coupling portion between the fixing member F1 and the tip reinforcement portion C2 of the bridges BG and BG'. Stress concentration is suppressed, the damage thereof is prevented, and the product life is extended.

In addition, the foreign substances are introduced into the panel guide groove (H2) through the finger insertion groove (H1), and then introduced into the panel for the drip tray 400 through the gap between the first reinforcement panel 300 and the base panel 100, Since the panel guide groove (H2) is formed smaller than the finger insertion groove (H1), foreign matter is primarily filtered while passing through the finger insertion groove (H1), the first reinforcement panel 300 and the base narrower than this Since the secondary filter is passed through the gap between the panels 100, only liquid rainwater or fine foreign matters having a very small volume and self weight are introduced into the water receiving members 400 and 600, so that the panel for water receiving by foreign matters ( 400 is prevented from being broken. In the case of the present embodiment, the panel 400 for the drip tray is used as the drip member, but the corrugated pipe 600 for the drip tray may be used, and a well-known foreign material may be prevented from being introduced into the space between the bridges. All things can be used as drip trays.

4A to 4C and FIGS. 5A and 5B illustrate different embodiments of the bridge connection structure according to the present invention, whereby the fixed ends 211 and 220 of the finger blocks 200 and 200 'are finger parts. Protruding downward of the 212, so that the panel guide groove H2 communicating with the finger insertion groove H1 is formed between the finger portion 212 and the base panel 100 of the finger block 200; Doing.

6A and 6B illustrate yet another embodiment, whereby a second reinforcement panel 500 is disposed between the fixed ends 211 and 220 and the base panel 100 of the finger blocks 200 and 200 '. In this way, the panel guide groove H2 communicating with the finger insertion groove H1 is formed between the finger portion 212 and the base panel 100 of the finger blocks 200 and 200 '.

Of course, the finger block 20, 20 '; 30, 30' according to the prior art can be used as the finger block, but such an integrated finger block (20, 20 '; 30, 30') is a manufacturing problem Due to this, the finger insertion groove H1 can not be formed large. As such, when the finger insertion groove H1 is large, foreign substances having a large volume and self weight are introduced into the finger insertion groove H1, and when the foreign substances having a large volume and self weight are introduced into the finger insertion groove H1, the bridge ( BG; BG ') is a problem that the expansion and contraction of the.

Therefore, it is preferable to use a prefabricated finger block as shown in Figures 4a to 6b.

According to this, the prefabricated finger block 200 (200; 200 '), a plurality of first support pieces 210 to form a quadrangular plate, a plurality of relatively shorter length than the first support piece 210 to form a quadrilateral plate shape The second support piece 220 is alternately fitted to the assembly bars 231 and 232 in order to be fixed to each other; The second support piece 220 is sandwiched between the joining portions 211 forming one tip of the first support piece 210, so that the finger portion 212 forming the other tip of the first support piece 210 is formed. The first support piece joint part 211 and the second support piece 220 protruding in the longitudinal direction from the second support piece 220 in the longitudinal direction, and between the finger parts 212 are formed with a finger insertion groove H1 and are fixed to each other. The fastening holes 240 penetrating the vertical height direction are formed, and the width W1 of the first support piece 210 is smaller than the width W2 of the second support piece 220.

Since the prefabricated finger blocks 200 and 200 'form a structure in which the first and second support pieces 210 and 220 are thinned to each other and assembled, the finger insertion grooves H1 are formed small, so that the volume and the weight thereof are small. Large foreign matters are not introduced into the finger insertion groove (H1), so that the stretching of the bridge (BG; BG ') is made smoothly.

4A to 4C, the height T1 of the first support piece 210 is lower than the height T2 of the second support piece 220, so that the second support piece ( The bottom part of 220 is projected downward from the junction part 211 of the 1st support piece 210, It is characterized by the above-mentioned.

In this case, the structures of the first support piece 210 and the second support piece 220 are simplified to facilitate the manufacture thereof, but external forces are applied to the assembly bars 231 and 232 in the vertical direction, and the second support piece is supported. There is a disadvantage that stress is concentrated on the piece 220.

5A and 5B, the height T1 ′ of the first support piece joint 211 is the same as the height T2 of the second support piece 220, and the first support piece is the same. The vertical height T1 of the finger portion 212 is formed to be lower than the vertical height T1 ′ of the joining portion 211, such that the first support piece finger portion 212 and the second support piece 220 correspond to each other. It is characterized by being gin.

In this case, although the lower part of the first support piece 210 forms a double structure, there is a manufacturing difficulty, but the external force in the vertical direction is not applied to the assembly bars 231 and 232, and the first support piece 210 is applied. And the second support piece 220 has the advantage of supporting the load evenly.

6A and 6B, the vertical height T1 of the first support piece 210 is the same as the vertical height T2 of the second support piece 220, and the first support pieces are opposed to each other. The second reinforcement panel 500 is sandwiched between the piece joint portion 211 and the second support piece 220 and the base panel 100 supporting them, so that the finger portion 212 of the finger block 200; And a panel guide groove H2 communicating with the finger insertion groove H1 between the base panel 100 and the base panel 100.

In this case, there is a disadvantage in that the number of members is increased by using the second reinforcement panel 500, but the first support piece 210 and the second support piece 220 can be easily manufactured, and the finger block 200; The first and second supporting pieces 210 and 220 evenly support the load applied to 200 ').

Meanwhile, the first reinforcement panel 300 may be freely moved in the panel guide groove H2 as shown in FIG. 4A, but as shown in FIGS. 5A and 6A, the fixing member F3 may be moved. It may be to be fixed to the base panel 100 or the tip reinforcement portion (C2) of any one bridge (200; 200 ').

The present invention is not limited to the embodiment as described above, and of course, various modifications can be made without departing from the scope of the following claims.

According to the present invention as described above, a panel guide groove which is in communication with the finger insertion groove is provided between the finger portion and the base panel of the finger block, the first reinforcement panel is fitted in the panel guide groove, Since both ends of the reinforcing panel are supported by being mounted on the base panel of the bridge facing each other, and the free end of the finger part is supported by being movable on the first reinforcement panel, the load applied to the finger block is evenly supported. Damage caused by stress concentration is prevented and product life is extended.

In addition, foreign matters are firstly filtered while passing through the finger insertion groove, and secondly are filtered while passing through the gap between the first reinforcing panel and the base panel, which is narrower than this, thereby preventing damage to the drip panel by the foreign materials. This has the effect of smoothly stretching the bridge.

In addition, when using a prefabricated finger block having a narrow finger insertion groove, foreign matters having a large volume and self weight are not introduced into the finger insertion groove, and thus the stretching of the bridge can be more smoothly obtained.
