[0019] The truss structure according to the present invention will be described in detail below with reference to the attached drawings.

[0020] A truss structure according to the present invention comprises, as shown in FIG. 1, a pair of current members (100) spaced apart from each other and arranged in parallel; a composite member (200) installed between the pair of current members (100); and a connecting member (300) provided in the current members (100), with the end side of the composite member (200) joined to fix the composite member (200).

[0021] The truss structure according to the present invention is applicable to any configuration for supporting high loads, such as a bridge or forming part of a building, as a structure for supporting high loads.

[0022] The above-mentioned current part (100) is a pair of frames spaced apart from each other and arranged parallel to each other, and can be configured in various ways.

[0023] At this time, the current part (100) is a frame having rigidity for support, and can be configured in various ways, such as a circular or rectangular frame.

[0024] For example, the above-mentioned current section (100) may include an upper current (110) and a lower current (120) that are arranged parallel to each other and spaced apart from each other.

[0025] The upper chord (110) is connected to the lower chord (120) through a composite member (200) and is configured to be installed parallel to the lower chord (120), allowing for various configurations.

[0026] At this time, the upper chord (110) may be provided with a connecting part (300) described later on its bottom surface through welding, and the upper end of the reinforcing part (200) may be directly connected through welding.

[0027] The above lower chord (120) is connected to the upper chord (110) through a composite member (200) and is configured to be installed parallel to the upper chord (110), allowing for various configurations.

[0028] At this time, the upper surface of the lower member (120) may be provided with a connecting part (300) described later through welding, and the lower end of the reinforcing member (200) may be directly connected through welding.

[0029] In addition, the above-mentioned current part (100) may additionally include a rigidity reinforcing part (130) inside to prevent deformation due to high load.

[0030] The above rigidity reinforcing member (130) is configured to reinforce rigidity by being provided inside at least one of the upper chord (110) and the lower chord (120), and various configurations are possible.

[0031] For example, the rigidity reinforcing member (130) may include a first rigidity reinforcing member (131) installed by being coupled to the inner upper surface of the lower chord (120) and extending downward, as shown in FIGS. 7 and 8, and a second rigidity reinforcing member (132) installed by being coupled to the inner lower surface of the lower chord (120) and extending upward.

[0032] More specifically, the first rigidity reinforcing member (131) and the second rigidity reinforcing member (132) are each provided by welding to the inner upper surface and bottom surface relative to the lower chord (120), and can be provided in a corresponding manner.

[0033] At this time, the first rigidity reinforcing member (131) may be in contact with or separated from the lower inner surface of the lower chord (120), and the second rigidity reinforcing member (132) may also be in contact with or separated from the upper inner surface of the lower chord (120).

[0034] Thus, the first rigidity reinforcing member (131) and the second rigidity reinforcing member (132) can prevent deformation by reinforcing the rigidity of the lower chord (120) through contact with the lower inner surface of the lower chord (120) and the upper inner surface of the lower chord (120), respectively, when the lower chord (120) is deformed due to an excessive load.

[0035] At this time, the rigidity reinforcing members (130) may be provided in multiple numbers spaced apart from each other along the longitudinal direction on at least one of the upper chord (110) and the lower chord (120), and may be spaced apart from each other at a certain interval. As another example, they may be provided in multiple numbers arranged so that the spacing becomes narrower from the edge toward the center.

[0036] The above-mentioned replica part (200) is configured to be installed between a pair of current parts (100), and various configurations are possible.

[0037] That is, the above-mentioned reinforcing member (200) may be configured to be installed between the upper chord (110) and the lower chord (120), forming a truss structure together with the chord member (100), supporting a high load, and maintaining rigidity.

[0038] At this time, the above-mentioned composite member (200) may include at least one of a diagonal structure that is connected diagonally to the upper chord (110) and the lower chord (120), and a vertical structure that is connected vertically. The following description is based on the premise of a diagonal structure, but is not limited thereto.

[0039] For example, the above-mentioned composite member (200) may include a diagonal member (210) having a length that forms a diagonal with respect to the upper chord (110) and the lower chord (120), as shown in FIG. 2, and an end member (220) that extends parallel to the joining surface of the upper chord (110) and the lower chord (120) from the end of the diagonal member (210).

[0040] At this time, the above-mentioned replica part (200) may be installed in the current part (100) by directly welding the end part (220) to the current part (100), or it may be installed indirectly connected to the current part (100) by welding it to the connecting part (300) described later and connecting the current part (100) to the connecting part (300).

[0041] More specifically, the above-mentioned reinforcing member (200) may be installed by directly joining the end portions (220) formed on both sides of the diagonal portion (210) to the bottom surface of the upper chord (110) and the top surface of the lower chord (120) through welding, respectively. As another example, the above-mentioned reinforcing member (200) may be indirectly connected to the current portion (100) by joining the end portions (220) formed on both sides of the diagonal portion (210) to the joining portion (300) provided on the bottom surface of the upper chord (110) and the joining portion (300) provided on the top surface of the lower chord (120), respectively.

[0042] In addition, unlike what was previously described, the above-mentioned composite part (200) may also be joined simultaneously with the end part (220) joined to the current part (100) at the second welded part (240), as shown in FIG. 2, while the diagonal part (210) is joined to the joint part (300) at the first welded part (230).

[0043] At this time, the above-mentioned replica part (200) can be installed by being guided through the coupling part (300), and more specifically, it can be installed by being joined to at least one of the coupling part (300) and the current part (100) by welding while being installed by being guided through the guide part (320) provided in the coupling part (300) described later.

[0044] The above-mentioned connecting part (300) is provided in the current part (100) and is configured such that the end side of the replica part (200) is connected to fix the replica part (200), and various configurations are possible.

[0045] For example, the above-mentioned connecting part (300) may be a cylindrical structure in which a hollow (301) is formed, as shown in FIG. 2, and may be configured to be installed by connecting it to the current part (100) through a third welded part (390) on the bottom surface.

[0046] At this time, the above-mentioned connecting part (300) can be joined by welding the end portion (220) of the reinforcing part (200) inserted into the hollow (301) to the current part (100), and in this process, a guide groove with an inclined cross-section can be formed on the upper surface to guide the installation position of the reinforcing part (200) and induce installation at the correct position.

[0047] At this time, the above-mentioned replica part (200) can be joined to the joining part (300) by joining through welding at the second welding part (230) while the diagonal part (210) is seated in the guide groove.

[0048] Meanwhile, as another example, the above-mentioned connecting part (300) is configured such that an inner inclined surface (330) is formed on at least a portion of the inner surface forming the hollow (301), as shown in FIG. 3, and the inner inclined surface (330) can be formed such that the inner diameter increases as it goes downward relative to the lower chord (120).

[0049] At this time, the above-mentioned replica part (200) can be inserted into the interior through the hollow (301) and the end part (220) can be joined by welding so that it comes into contact with the contact surface of the current part (100).

[0050] In this case, the diagonal portion (210) of the above-mentioned composite portion (200) can be joined by welding adjacent to the opposite inner inclined surface (330) of the joining portion (300).

[0051] Meanwhile, it is also obvious that the inner inclined surface (330) of the above-mentioned joint (300) may be formed such that the inner diameter increases as it moves upward relative to the lower chord (120).

[0052] In addition, as another example, the above-mentioned connecting part (300) may be configured to have a truncated cone shape as shown in FIG. 4, and may include an upper surface (350) forming a hollow (301) and a side part (340) extending from the upper surface (350) and forming a side with an incline.

[0053] At this time, the above-mentioned replica (200) can be installed along the inner surface of the side portion (340) while inserted through the upper surface (350) via the hollow (301).

[0054] That is, the above-mentioned duplicate portion (200) can be installed so that the diagonal portion (210) is guided on the inner surface of the opposite side portion (340) with the end portion (220) omitted, and at this time, the duplicate portion (200) can be positioned at a position offset from each other on a plane so as not to interfere with each other.

[0055] Meanwhile, as another example, the above-mentioned coupling part (300) may have a groove (302) formed on its upper surface as shown in FIG. 5, and the entire bottom surface may be in contact with and coupled to the current part (100).

[0056] At this time, the connecting part (300) can be joined by welding to the reinforcing part (200) which is inserted into and installed in the groove part (302), and more specifically, the end part (220) can be joined to the groove part (302) by welding.

[0057] For example, the coupling part (300) may include a coupling body (310) that is coupled to the current part (100) and has a groove (302) formed on its upper surface, and a guide part (320) formed so that the replica part (200) is inserted into the coupling body (310).

[0058] At this time, the guide portion (320) can be applied as an installation hole formed through the side at an angle corresponding to the diagonal portion (210), as shown in FIG. 5.

[0059] More specifically, the guide portion (320) may be formed as an installation hole formed through the side at an angle corresponding to the diagonal portion (210), and the diagonal portion (210) may be joined to the guide portion (320) by welding through the diagonal welding portion (231) as the first welding portion (230), and the end portion (220) may be joined by welding through the groove welding portion (232) formed in the groove portion (302).

[0060] In addition, as another example, it may be applied as a guide groove formed on the upper edge surface forming the groove (302) of the combined body (310) to have a width corresponding to the replica part (200).

[0061] At this time, the combined body (310) may be formed to form an elliptical shape in a planar shape as shown in FIG. 6, and as another example, a circular or rectangular shape may also be applied.

[0062] Meanwhile, the above-mentioned combined body (310) is elliptical in shape in a planar form, and the guide part (320) can be formed at each end forming the long axis so that the duplicate part (200) is installed at a position corresponding to the long axis.

[0064] The foregoing merely describes some preferred embodiments that can be implemented by the present invention. As is well known, the scope of the present invention should not be interpreted as being limited to the above embodiments, and all technical concepts that share the fundamental principles with the technical concept of the present invention described above shall be considered to be included within the scope of the present invention.
