Various embodiments of the present invention will now be described by way of specific embodiments shown in the accompanying drawings. The differences between the embodiments of the present invention described below are to be understood as mutually exclusive. That is, the specific shapes, structures, and characteristics described may be embodied in other embodiments in accordance with one embodiment without departing from the spirit and scope of the present invention, It is to be understood that the arrangements may be altered, where like reference numerals refer to like or similar features throughout the several views, and length and area, thickness, and the like may be exaggerated for convenience.

1 is a plan view of a support unit of FIG. 1, and FIG. 3 is a cross-sectional view of a pipe extension joint according to an embodiment of the present invention. FIG. Fig.

1 to 3, a pipe expansion joint apparatus 100 according to an embodiment of the present invention includes a plurality of flanges 111 spaced apart from each other to interconnect pipes 105 A plurality of support units 120 arranged between a plurality of flanges 111 so as to support a plurality of flanges 111 respectively and a plurality of support units 120 And a tie rod unit 130 coupled through a plurality of support units 120 so as to be variable.

According to the present invention, since the support unit 120 to which the tie rod unit 130 is coupled is disposed between the plurality of flanges 111 and the overall length can be shortened by the conventional expansion joint, .

That is, the pipe expansion joint apparatus 100 according to the present embodiment can sufficiently install the pipe expansion joint apparatus 100 by avoiding interference with the equipment in a space where a large number of equipment products are installed, such as an engine room.

The pipe expansion joint apparatus 100 according to this embodiment can be disposed between the pipes 105 to attenuate vibrations and shocks caused by thermal expansion or mechanical force between the pipes 105. [ The joint unit 110 itself connected to the pipes 105 is provided so as to be able to perform buffering as in the flexible structure described later.

For this purpose, the joint unit 110 may be provided with a semicircular wrinkle 112 to facilitate expansion and contraction. That is, the joint unit 110 may be provided in a flexible structure or material so as to withstand the expansion stress applied to the pipes 105.

Hereinafter, the components of the pipe expansion joint apparatus 100 according to the present embodiment will be described in detail.

1 to 3, the support unit 120 includes an annular support portion 121 provided with holes along the circumferential direction so as to be engageable with the flange 111, And a plurality of rod engaging portions 125 provided at the outer periphery of the annular support portion 121. [

As described above, the annular support portion 121 according to the present embodiment is a panel formed in an annular shape, and can be supported by the flanges 111 so as to be in contact with the flanges 111, respectively.

The tie rod unit 130 is coupled to the rod coupling part 125. The tie rod unit 130 is coupled to the rod coupling part 125. [ At this time, the annular support portion 121 of the support unit 120 can be supported by the tie rod unit 130 coupled to the rod engagement portion 125.

The tie rod unit 130 according to this embodiment includes a support rod 131 which is coupled through the rod coupling part 125, a coupling nut 133 which is coupled to both sides of the support rod 131, And may include support sleeves 135 disposed between the plurality of flanges 111 to limit movement of the unit 120 and inserted into the support rods 131.

The tie rod unit 130 receives the impact applied from the respective flanges 111 to the annular support portion 121 through the rod coupling portion 125. At this time, the support rod 131 is coupled through both the rod engaging portions 125 and the coupling nut 133 is coupled outwardly between the flanges 111. The movement of the flanges 111 is transmitted to the support rod 131). ≪ / RTI >

That is, a clearance is provided between the support sleeve 135 and the rod engaging portion 125, the rod engaging portion 125 can be moved by the clearance, the flanges 111 can be moved by the clearance, Further movement is limited.

The rod-engaging portions 125 to which the tie-rod unit 130 is coupled may be arranged at intervals of 180 degrees.

Accordingly, the tie rod unit 130 can be arranged symmetrically on both sides to limit the movement of the flanges 111 due to impact and vibration applied to the flanges 111. [

On the other hand, the tie-rod units 130 can be arranged at intervals of 90 degrees.

As shown in FIGS. 1 to 3 again, the impact and vibration applied to the flanges 111 described above may be limited by the tie-rod unit 130, but the joint unit 110 itself So that it can be attenuated.

Further, the tie rod unit 130 may be provided with a spring member, though not shown, to elastically limit the movement of the support sleeve 135. With such a spring member, a coil spring may be selected which is disposed between the flanges 111 and the support sleeve 135.

Accordingly, the impact generated between the pipes 105 to be connected and the connection state of the pipes 105 are maintained even if they occur, and the pipes 105 and the connection structure can be protected from impact and vibration.

Meanwhile, according to another embodiment of the present invention, a vessel or an offshore structure including the above-described pipe expansion joint apparatus can be provided.

Such a ship or an offshore structure is advantageous in that the impact and vibration between the pipes 105 are damped by the joint unit 110 as described above so that not only the pipes 105 can be protected but also between the flanges 111 The connection structure of the entire pipe can be configured compact by disposing the support unit 120 to which the tie rod unit 130 is coupled and the flanges 111 can be supported.

While the present invention has been particularly shown and described with reference to exemplary embodiments thereof, it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention as defined by the appended claims. Deletion, addition or the like of the present invention may be variously modified and changed within the scope of the present invention.
