Abstract

According to the present invention, the expansion joint combined gutter devices are respectively disposed on an opposite surface of a pair of bridge slabs which are mutually opposite to each other, and comprises: a first member to guide a fluid introduced between a pair of slabs; and a second member to introduce the fluid guided from the first member, discharging to the outside.

Description

[0001] Description [0002] Expansion Joint Combined Water Spout Apparatus [

More particularly, the present invention relates to a stretch-jointed water-receiving device capable of easily attaching / detaching a slab to a slab, and capable of easily guiding a fluid introduced into a stretched / .

The upper plate of the bridge is not constituted of a single structure but is constituted by interconnecting a plurality of slabs.

The expansion joint is a device that is provided between interconnected slabs to compensate for the expansion and contraction of the slab. Since the slab of a bridge usually expands or shrinks according to the temperature change and the load, the slab constituting the bridge is installed so as to have a slope indicating an appropriate interval for every predetermined length. The expansion joint is installed between the slab and the slab so as to prevent damage to the slab and smooth communication of the vehicle.

The railway bridge in the bridge is composed of a plurality of piers and a plurality of top plates on both upper and lower ends of the piers. The connecting portions of the upper and lower plates absorb the expansion and contraction of the upper plate, The upper plates are spaced apart from each other so as to absorb a variation in the distance between the upper plates due to the movement of the train. At this time, a spacing gap is provided to accommodate the displacement of the upper plate and to connect the upper plate and the upper plate.

 In addition, when a fluid such as rainwater flows into the space between the slabs, various impurities introduced together with the fluid have a problem of corroding various facilities constituting the bridge. Particularly, since calcium chloride sprayed in winter to remove frost on the road surface is highly corrosive, it will corrode the facilities of bridges and deteriorate the performance and lifespan of the bridges so that the fluid flowing between the slabs should not touch the bridge substructure .

Constitution of integrated water splash device with expansion joint

1 is a perspective view of a slab provided with a water-dispersion type integrated water-based apparatus according to the present invention. The water-splash joint 10 according to the present invention is constructed such that a slab 300 provided between and connected to slabs constituting a road or a bridge is expanded and contracted while a fluid 500 such as rainwater flows out to the lower portion of the bridge The fluid 500 is introduced and discharged to one side. Such a stretch-jointed integral type water-receiving apparatus 10 is composed of a first member 100 and a second member 200, as shown in Fig.

The configuration of the first member

2 is a perspective view of a first member according to the present invention. 1 and 2, the first member 100 is provided on the joining surface of one of the joining surfaces of the pair of the slabs 300 coupled to each other, Thereby inducing the flow of the inflowing fluid 500. The first member 100 includes a first transverse member 110, an induction member 120, and a first fixing member 130.

The first transverse member 110 is provided to protrude in the coupling direction along the coupling surface so that the upper surface of the first transverse member 110 corresponds to the upper surface of the slab 300 on the coupling surface between the slabs 300. In other words, the first transverse member 110 is a plate-shaped member having a long width in the longitudinal direction of the coupling surface of the slab 300 and a predetermined interval in the direction of the adjacent slabs 300. At this time, the upper surface of the first transverse member 110 is formed so as to form the same plane as the upper surface of the slab 300 so as not to obstruct the passage of a vehicle or the like passing through the upper portion of the slab 300.

1 and 2, the first transverse member 110 has a width direction opposite to the one surface coupled with the coupled slab 300 and facilitates the inflow of the fluid 500 and the passage of the vehicle To form a saw tooth shape. At this time, it may be a finger shape. However, when the temperature expansion and contraction of the slab 300 is not large, it may be a date other than a tooth or finger shape. The shape of the first transverse member 110 is similar to that of a telescoping joint commonly used in the art.

The first transverse member 110 may be made of a metal material to prevent breakage due to passage of a vehicle or the like.

The guide member 120 is provided at one end of the first transverse member 110, preferably at one end thereof coupled to the slab 300 to which the first transverse member 110 is fixed, (500) to the second member (200). The guide member 120 may be formed in any shape as long as it can guide the fluid 500 to the second member 200. Preferably, the guide member 120 has an ' So that the first member 100 is entirely shaped as a " C " shape. At this time, the bottom surface of the guide member 120 may be inclined so that the height of the bottom surface of the guide member 120 gradually decreases from one end coupled to the first lateral member 110 to the other end to smooth the flow of the fluid 500. As described above, since the bottom surface is formed of an inclined surface, the fluid 500 is not held on the first member 100 but is guided to the second member 200 naturally by its own weight along the inclined surface.

3 is a side view of a first member according to a variant of the invention. As shown in FIGS. 3A and 3B, the first member 100 may have various shapes. Although the first transverse member 110 is not greatly different from the first transverse member 110, the guiding member 120 is not formed in the shape of a letter "B", but may be provided so that the inclined surface is directly coupled to one end of the first member 100, Quot; b " shape having a curved shape. In this way, the first member 100, particularly, the guide member 120 may be formed in any shape as long as it can easily guide the fluid 500 in addition to the above-described structure.

The guide member 120 is formed to protrude relatively longer than the length of the first transverse member 110 in order to easily guide the inflow fluid 500 to the second member 200. 1 and 2, since the fluid 500 flowing in the slab 300 is introduced at the end of the first transverse member 110, the end of the guiding member 120 is positioned at the first transverse member 110 Or if the length of the guiding member 120 is relatively shorter than the length of the first transverse member 110, the introduction of the introduced fluid 500 may not be easy. The length of the inflow member may be relatively longer than the length of the first transverse member 110 such that the end of the inflow member is positioned on the first transverse member 110 relative to the first transverse member 110 and the engagement portion of the inflow member. And extend to a position farther from the terminating end.

The first fixing member 130 is disposed on one side of the first transverse member 110 or the induction member 120 and includes a first transverse member 110 and an induction member 120 and a first side 100, And the first member 100 is fixed to the slab 300 by projecting in a direction in which the slab 300 contacts. The first fixing member 130 may be any device as long as the first member 100 can be coupled to the slab 300 and fixed.

1 to 3, the first fixing member 130 may be formed of a 'a' shaped protrusion integrally formed with the first transverse member 110 or the guiding member 120. At this time, the slab 300 has a groove corresponding to the first fixing member 130, so that the first member 100 can be inserted into the slab 300 by sliding the slab 300 in the slab 300. [ The first fixing member 130 may have any shape as long as the first member 100 can be stably coupled to the slab 300 even if the first fixing member 130 is not 'a'.

The first fixing member 130 may be a separate member from the first member 100 such as a bolt or a screw so as to fix the first member 100 to the slab 300. [

The first transverse member 110 of the first member 100 having the above-described structure uses a rigid metal so as to sufficiently support the load of the vehicle, and the induction member 120 is a stretch joint between the slabs 300 Such as metals, alloys, steel plates, or plastics, which are stretchable.

The configuration of the second member

4 is a perspective view of a second member according to the present invention. 1 and 4, the second member 200 includes a first member 100 and a second member 200 on the joining surfaces of the slabs 300 of the other of the joining surfaces of the pair of the slabs 300 coupled to each other. And is adapted to store and discharge the fluid 500 guided from the first member 100 to the outside. The second member 200 includes the second transverse member 210, the receiving member 220, and the second fixing member 230.

The second transverse member 210 is provided to protrude in the coupling direction along the coupling surface so that the upper surface of the second transverse member 210 corresponds to the upper surface of the slab 300 on the coupling surface between the slabs 300. In other words, the second transverse member 210 is a plate-shaped member formed to be long with the coupling surface of the slab 300 in the longitudinal direction and having a predetermined interval in the direction of the adjacent slabs 300. At this time, the upper surface of the second transverse member 210 is formed so as to form the same plane as the upper surface of the slab 300 so as to facilitate the passage of a vehicle or the like passing through the upper part of the slab 300.

The second transverse member 210 preferably has a shape corresponding to the first transverse member 110.

The receiving member 220 is provided at one end of the second transverse member 210, preferably at one end thereof coupled with the slab 300 to which the second transverse member 210 is fixed, (500) is stored and discharged to the outside. The housing member 220 may have any shape as long as it can store a certain amount of the fluid 500 guided from the first member 100. However, as shown in FIGS. 1 and 4, it is preferable that the second member 200 is formed in an 'a' shape corresponding to the guide member 120 of the first member 100, 100 ").

At this time, a projecting portion is protruded upward so that a certain amount of fluid 500 can be received and flow at the end of the housing member 220. As described above, since the projecting portion is protruded at the end of the housing member 220, the fluid 500 introduced into the housing member 220 can receive a certain amount of the fluid 500 without leaking to the outside.

An outlet port (not shown) may be formed in at least one of the center and both ends of the housing member 220 to discharge the fluid 500 stored in the housing member 220 to the outside. Not shown) can be connected. Thus, the fluid 500 received in the receiving member 220 through the outlet and the drain port can induce the discharge of the fluid 500 to the user's desired location. At this time, it is preferable that the housing member 220 forms an inclined surface toward the outlet side so that the fluid 500 can easily flow into the outlet. At this time, it is preferable that the direction of the inclined surface is formed in the direction opposite to the inclination of the transverse direction of the road so that the flowing water of the road can sweep off the foreign matter accumulated in the receiving member 220 sufficiently.

That is, when the transverse ship of the road is formed so as to gradually decrease from right to left, as shown in FIG. 0, the second transverse member 210 is formed so as to gradually decrease from the right to the left so as to correspond to the transverse direction of the road The lower surface of the housing member 220 is inclined so as to gradually decrease from the left to the right and the outlet port is formed at the right end of the housing member 220. As described above, when the transverse direction of the road is formed, a relatively large amount of the fluid 500 flows into the left side of the housing member 220 than the right side. At this time, the fluid 500 accommodated in the housing member 220 flows from left to right, and foreign matter accumulated on the housing member 220 can be easily removed through the flow of the fluid 500.

The inclination angles of the second transverse member 210 and the receiving member 220 may be variously changed in consideration of transverse folding of the road.

6 is a side view of a second member according to a variant of the invention. 6A and 6B, the second member 200 may also have various shapes. Although the second transverse member 210 is not different from the above-described configuration, the receiving member 220 is formed in a 'J' shape or an inverted pentagon shape in which a part of the portion coupled with the first member 100 is cut, Any shape may be used as long as the fluid 500 can be stored and flowed.

The receiving member 220 is formed to protrude relatively long as compared with the length of the second transverse member 210 in order to easily accommodate the fluid 500 guided from the first member 100.

1 and 4, since the fluid 500 introduced from the first member 100 is guided along the guiding member 120 of the first member 100, the end of the guiding member 120 The length of the guiding member 120 and the length of the receiving member 220 should be set appropriately so that the end of the guiding member 120 is located inside the terminating end of the receiving member 220 and the end of the guiding member 120 is not in contact with the wall surface of the receiving member 220 .

If the end of the guide member 120 is brought into contact with the wall surface of the receiving member 220, the fluid 500 may not be easily guided into the receiving member 220, This is because the fluid 500 introduced through the induction member 120 may leak to the outside unless it is positioned inside the member 220.

The ends of the guiding member 120 of the first member 100 and the receiving member 220 of the second member 200 are respectively longer than the lengths of the first transverse member 110 and the second transverse member 210 It is preferable that they are projected relatively long to be overlapped with each other. At this time, when any one of the guide member 120 and the receiving member 220 is formed long enough to facilitate the introduction and the reception of the fluid 500, the other one may be a first cross member 110 or a second cross member The protrusion 210 may protrude to the same length as the protrusion 210.

The second transverse member 210 of the second member 200 having the above-described construction uses a rigid metal so as to sufficiently support the load of the vehicle, and the accommodating member 220 is a stretch joint between the slabs 300 Such as metals, alloys, steel plates, or plastics, which are stretchable.

The second fixing member 230 protrudes in a direction in which the second member 200 and the slab 300 are in contact with one side of the second transverse member 210 or the receiving member 220 to support the second member 200 in the slab 300). The second fixing member 230 may be any device as long as it can couple and fix the second member 200 to the slab 300. However, it is preferable that the second fixing member 230 has the same configuration as the first fixing member 130 described above.

The use of integrated water splash device

First, as shown in FIG. 1, a flexible joint-and-water integrated type water receiving apparatus 10 according to the present invention is installed at a connecting portion of a plurality of slabs 300 constituting a bridge. At this time, the elastic jointed-type water-receiving apparatus 10 may be installed after the slab 300 is installed or after the elastic joint-type water-receiving apparatus 10 is assembled before the slab 300 is installed. The installation order of the expansion joint integrated type water receiving apparatus 10 can be selectively performed according to the situation of the construction site and the construction method.

The first and second fixing parts of the first member 100 and the second fixing part 200 are coupled to each other by a first fixing part and a second fixing part, respectively, And the second fixing part can be engaged to be inserted in a slide manner. In another example, the first fixing part and the second fixing part may be formed of bolts or screws and may be coupled to the slabs 300 through bolt fastening or screw fastening to the respective slabs 300. It can be coupled in various ways depending on the shape and the type of the first fixing part 230 and the second fixing part 230.

FIG. 7 is a side view showing a combined state of the expansion joint and the integrated waterproofing apparatus according to the present invention. As shown in FIG. 7, the stretch-jointed integrated type water receiving apparatus 10 is provided such that the first member 100 and the second member 200 facing each other are spaced apart from each other by a predetermined distance. This will be described in more detail as follows.

The first transverse member 110 of the first member 100 and the second transverse member 210 of the second member 200 may be filled with the fluid 500, The first member 100 and the second member 200 are provided so as to be spaced apart from each other by an interval d. At this time, the end of the guide member 120 of the first member 100 is also spaced apart from the wall surface of the receiving member 220 of the second member 200 by a predetermined distance D.

The distance D between the end of the induction member 120 and the wall surface of the receiving member 220 is longer than the distance d between the first and second transverse members 110 and 210 It is preferable to be spaced apart. This is because the gap between the first member 100 and the second member 200 becomes narrow due to the expansion and contraction of the slab 300 when the gap between the first and second members 110 and 210 d of the guide member 120 is narrower than or equal to the distance D between the end of the guide member 120 and the wall surface of the housing member 220, the end of the guide member 120 contacts the wall surface of the housing member 220, The induction of the fluid 500 flowing between the member 100 and the second member 200 may not be smooth.

However, the distance D between the end of the guide member 120 and the wall surface of the receiving member 220 is relatively longer than the distance d between the first and second transverse members 110 and 210 A space may be formed between the end of the induction member 120 and the wall surface of the receiving member 220 even if the first transverse member 110 and the second transverse member 210 are in contact with each other as much as possible, It can be smoothly performed.

If the first horizontal member 110 and the second horizontal member 210 are formed in a straight shape other than a saw tooth or a finger shape because the temperature expansion and contraction of the slab 300 is not large, Although there is elasticity such as a sponge between the two transverse members 210, a material through which water can pass may be inserted and used.

FIG. 8 is a side view showing the use of a bridge equipped with a flexible joint-type water-receptacle apparatus according to the present invention. The flow of the fluid 500 using the flexible joint-and-water system 10 according to the present invention is as shown in FIG. The flow of the fluid 500 will be described in more detail as follows.

A fluid 500 such as rainwater, cleaning sewage or the like is generated in the upper part of the slab 300 at the time of rainstorming or cleaning the bridge slab 300. Leaving the generated fluid 500 on the upper side of the slab 300 may interfere with the passage of the vehicle while the vehicle is traveling, or may cause an accident if it is serious. Therefore, as described above, the elastic joint integrated type water receiving apparatus 10 for discharging the fluid 500 is installed between the slabs 300.

The fluid 500 flows on the slab 300 and flows in the direction of the stretch joint integral water-receiving device 10. The fluid 500 thus flowing flows into the space between the first transverse member 110 of the first member 100 and the second transverse member 210 of the second member 200.

The inflow fluid 500 flows into the induction member 120 and flows along the inclination of the induction member 120 to the second member 200 and more specifically to the receiving member 220 of the second member 200 .

The fluid 500 introduced into the housing member 220 is discharged to a position designated by the installer through a drain hole and a drain pipe formed at one side of the housing member 220. At this time, since the housing member 220 can receive a certain amount of the fluid 500 by the projecting portion, the fluid 500 that is not leaked arbitrarily in the housing member 220 is not generated, .

Even if the slab 300 is elongated or contracted, the distance d between the first transverse member 110 and the second transverse member 210 is greater than the distance d between the end of the guiding member 120 and the wall surface of the receiving member 220 The interval D is relatively long and therefore the space between the end of the induction member 120 and the wall surface of the receiving member 220 is not limited to the space between the first transverse member 110 and the second transverse member 210, So that the flow of the fluid 500 is smoothly performed.

As described above, those skilled in the art will understand that the present invention may be embodied in other specific forms without departing from the spirit or essential characteristics thereof. It is therefore to be understood that the above-described embodiments are to be considered in all respects as illustrative and not restrictive. The scope of the present invention is defined by the appended claims rather than the detailed description and all changes or modifications derived from the meaning and scope of the claims and their equivalents should be construed as being included within the scope of the present invention.
