[0001] PRECAST COPING STRUCTURE FOR BRIDGE USING PRECAST DECK [0002]

The present invention relates to fast common pre-cast coping using precast coping decks. More specifically, the present invention relates to rapid pre-cast coping using a precast coping deck in which files can be installed on the basis of streams and seas, and precast copings and bottom plate girders can be simply and continuously constructed on the head of a file.

1A shows an example of a conventional fishing bridge.

First, the breakwater 10 is a kind of dam structure that is artificially constructed so as not to be affected by waves, waves, and the like. A slope is formed on both sides, and a clay stone and a terracotta are installed on the slope, respectively.

Normally, fishing is possible around the terracotta, but there is a risk of safety accidents such as falls. A connecting bridge (connecting road) 20 is constructed from the breakwater.

It can be seen that the connecting bridge is installed so as to extend from the breakwater to the sea side, and the fishing bridge 30 capable of catching the fishing spot is installed orthogonally to the connecting bridge 20.

When the fishfield 40 is formed in front of the fishing bridge 30, fishing is performed. Such a fishing ground 40 is provided with a fish reef 50 in advance in the sea to artificially attract and form fish.

At this time, the connecting bridge 20 and the fishing bridge 30 can be constructed in the form of a bridge, because it is not a load to which a large load acts.

Such fishing bridges are shown in Fig. 1B.

That is, a reef bottom plate 42 formed on the upper surface of the reef 41 and including a through-hole H formed in the vicinity of the reef to pierce the reef; A pile (43) installed through the through hole and provided on the ground below the reef bottom plate and extending above the reef bottom plate so as to protrude above the water surface; And a bottom plate (44) installed on the pile head to be connected to the breakwaters.

At this time, the bottom plate 44 is formed so that one side extends directly over the part of the breakwater, and the other side is connected to another part of the breakwater, so that the breakwater is formed as one side of the fishing bridge, so that the fishing line is formed inside the breakwater and the fishing bridge And so on.

Therefore, it can be seen that the conventional fishing bridge is provided with a connection road from a breakwater or the like in order to secure accessibility, and it is effective to use such a fishing bridge together for a viewing purpose, not just for fishing, That's it.

1C shows an example of a prefabricated precast pier construction that can be rapidly constructed in the prior art.

That is, a bridge pillar portion and a coping portion are manufactured by a pre-casting method, and the upper end of the pillar portion is inserted through a bottom surface of the coping portion to connect the pillar portion and the coping portion.

That is, after the coupling rod 26 protrudes from the upper end of the pierced column part 2, the pierced column part is integrally assembled to the pier foundation. The coping portion 3 is formed with an insertion hole 31 so that an upper portion of the pierced column portion 2 can be inserted from the bottom surface and a coupling plate 32 having a through hole 34 formed in the insertion hole 31, So that the engaging rod 26 is inserted into the through hole 34. As shown in FIG.

At this time, an entry hole 33 is formed from the upper surface of the coping portion 3 to the through hole 34, so that the coupling portion 26 is inserted into the entrance hole. It can be understood that the piercing column portion 2 and the coping portion 3 are integrally assembled with each other by inserting the fastening means through the entry hole 33. [

However, the rapid construction of precast pier is to be applied to general bridges, and it is less cost effective to apply to bridges used for fishing and pipe fittings.

In other words, since it is not a load to which a large load acts like a vehicle bridge, it is very important to make a quicker construction. Therefore, in installing a bottom plate to a file, a precast method is inevitably used. I have to ask for a bottom plate.

However, as the floor size increases, the weight of the floor increases, which can affect the number of installation of the file. Therefore, it is necessary to construct a rapid bridge that can construct the bottom plate area in some way.

Accordingly, it is an object of the present invention to provide a pre-cast coping deck which can be easily installed, can be quickly installed, can be arranged as variously as possible, It is a technical problem to solve a common precast copping in a fast case.

In the construction of a bridge structure in which a plurality of files are integrated in the precast coping and continuously constructed in the extension direction of the bridge, the plurality of files and the precast copings can be integrated more safely and can be rapidly constructed.

In order to achieve the above object,

First, it is installed in such a manner that the file is extended up to the water surface without a foundation, the precast coping is inserted into the pile head, and the precast bottom plate girder is fixed in the longitudinal direction so as to cross the precast coping.

That is, the precast coping serves to serve as a fulcrum for connecting the precast deck girder in the longitudinal direction, and to transmit the working load to the deck by fastening the precast deck girder and the deck to each other.

At this time, the precast bottom plate girder is a plate structure which is manufactured in a predetermined length and shape,

In particular, a precast coping deck, which is integrally installed at the end of the precast coping, is installed to extend the bottom plate area around the precast coping.

That is, the precast coping deck, which serves to expand the bottom plate area, is directly fixed and installed to the pre-cast coping where the file is installed, and the pre-cast coping deck, precast coping and precast deck girder are integrated.

Second, the precast coping deck may be formed in various shapes such as a square or semicircular shape, but the connecting rods and fixing nuts are used so that the bottom is supported at both ends of the precast coping deck, but the fixing rods are fixed. In this case, the pre-cast coping deck is further provided with a deck connecting reinforcing bar coupled to the reinforcing bars of the precast copings so that the precast coping deck can be safely supported without being conducted at both ends.

The vertical connecting rods are extended to the upper surfaces of both end portions of the precast coping so that the vertical connecting rods are inserted into the through holes formed in the vertical grooves of the precast coping deck to be fixed by the fixing nuts, Such as a shrinkage concrete pouring into the connection of the bottom plate girder and the vertical grooves of the precast coping deck.

Third, the precast coping is formed of reinforced concrete, and a file insertion hole is formed to penetrate the precast coping so that a pile head can be inserted. At this time, the file insertion hole of the precast coping is inserted downward in the file head, and the file head support is installed across the middle of the file insertion hole such that the top of the file is inserted and held in the middle of the file insertion hole.

Such a pile head support is preformed in the pile insertion hole when making precast copings, so that the field work for supporting the pile head is made very simple.

Fourth, a pile head bracket capable of hanging a concrete filled finish plate is installed on the pile head. Therefore, the upper end of the pile head bracket is supported on the bottom of the pile head support, but the pile head support is constrained to the pile head bracket by using the claw, so that the precast copping is installed more stably .

Fifthly, the pile head reinforcing net is inserted into the pile insertion hole to set the pile head reinforcing net to protrude from the top surface of the precast coping, the precast bottom pile girder is mounted so that both ends are mounted on the precast copping, The bridges are completed by placing the concrete in the upper part of the file and the precast coping and continuing the focal point.

Sixth, the precast coping is made of reinforced concrete, and a file insertion hole is formed to penetrate the precast coping so that the pile head can be inserted. At this time, the file insertion hole of the precast coping is inserted downward in the file head, and the file head support is installed across the middle of the file insertion hole such that the top of the file is inserted and held in the middle of the file insertion hole.

In addition, a pile head bracket can be installed on the head of the pile, which can be fitted with a concrete filled finish plate. Therefore, the upper end of the pile head bracket is supported on the bottom of the pile head support, but the pile head support is constrained to the pile head bracket by using the claw, so that the precast copping is installed more stably .

Further, the file head reinforcing steel net is inserted into the file insertion hole, the file head reinforcing steel net is set so as to protrude from the top surface of the precast coping, the precast bottom plate girder is mounted so that both ends are mounted on the precast coping, Concrete is poured into the interior and precast copings to complete the bridges by continuing the bridges.

It is possible to provide a common precast coping at a rapid speed, which facilitates the installation of a sighting and fishing deck capable of rapid construction by using a pile as a pillar member.

In addition, the viewing and fishing decks are integrated together when connecting precast deck girders to pre-cast copings using pre-cast coping decks, making it possible to provide rapid, common precast copings that are structurally advantageous and very efficient. .

In addition, the precast coping of the present invention is such that the file head is securely inserted and supported by using the file head bracket in the file insertion hole with the bottom surface of the precast coping formed in the file insertion hole formed in the file insertion hole, Height setting becomes possible.

Especially, in the method of installing precast coppings directly on the pile head which has been previously installed in the river or sea, the precast copping can be installed immediately after the height of the pile head is adjusted, so that rapid construction is possible and the height can be adjusted .

Also, according to the present invention, a file head is securely inserted and supported by using a pile head bracket in the pile insertion hole at the bottom of a precast coping formed in a pile insertion hole of a pile head support, so that precast coping can be stably installed and height set .

In order to secure the safety of the bridges installed in the bridges such as cranes in the installation of file and precast coping and precast deck girder in the direction of extension of the bridge, It is possible to secure construction quality control and safety.
