[0002] Generally, a truss refers to a structure that supports external forces by connecting multiple truss members, which are linear members, to form a triangular or triangular grid structure, and each truss member is configured to primarily bear tensile or compressive forces.

[0003] These trusses can be applied to truss bridges such as railway bridges and road bridges, roof trusses of buildings such as factories, gymnasiums, and logistics warehouses, truss structures of steel pipes and angles, and space trusses of exhibition halls and dome structures.

[0004] As a technology related to the connection structure of conventional truss members, Korean Published Patent No. 10-2002-0074874, titled "Coupling member for truss structure," has been disclosed. This coupling member for a truss structure comprises: a groove formed with a step corresponding to both ends of two caps forming the coupling member; and a fastening ring provided on the groove to prevent the caps from detaching and to allow both caps to open elastically.

[0005] However, while such conventional technology enables connection to connecting members, it had the problem of making it difficult to achieve a rigid connection due to the structural characteristics of these connecting members.

[0006] Therefore, the connection method of truss members generally relies heavily on welding, but this relies heavily on the skill level of the workers, resulting in uneven construction quality and causing a decrease in structural reliability. It also leads to an increase in self-weight, making it structurally disadvantageous, and has the problem of requiring a large number of personnel and time for construction. The problem to be solved

[0010] The above node plate is provided in pairs, each of which is formed in a semicircular shape, and each is connected to the other by a hinge joint at one end, and each of the above node plates is provided with a groove for receiving the frame member, and can be fixed around the frame member by welding to the edge of the groove.

[0011] The apparatus further includes a fixing plate that mediates the coupling of the truss member to the coupling plate by being fixed to the end of the truss member and fixed by bolting while in contact with the coupling plate, and the fixing plate may be fixed via a connecting piece or connecting cone provided at the end of the truss member.

[0012] It further includes a spaced connection member that connects a plurality of the node plates fixed in parallel to the frame member while maintaining a distance from each other, and the spaced connection member may allow the segment plate of each node plate to be penetrated by a connecting bolt and the segment plate to be supported by a plurality of connecting nuts fastened to the connecting bolt.

[0013] The above-mentioned connecting plate can be fixed by being simultaneously fitted into a plurality of the above-mentioned node plates, which are fixed parallel to the above-mentioned frame member, by the above-mentioned fitting part. Effects of the invention

[0019] Referring to FIGS. 1 to 5, the prefabricated truss coupling structure (100) according to the first embodiment of the present invention is a structure for coupling a truss member (20; see FIG. 7) to a frame member (10), and the truss member (20) is arranged in a triangular shape in two dimensions or three dimensions to implement a truss structure, and may include a node plate (110), a coupling plate (120), and a fitting part (130).

[0020] The node plate (110) is fixed to wrap around the perimeter of the frame member (10) by means of a plurality of split plates (111, 112) connected by hinge joints. The node plate (110) serves as a foundation for the truss member (20; see FIG. 7) to be fixed to the frame member (10).

[0021] As in the present embodiment, the node plate (110) may be provided as a pair of split plates (111, 112), each formed in a semicircular shape, and each may be connected to the other by a hinge joint (114), and a groove (113) for receiving a frame member (10) may be provided in each of the split plates (111, 112), and may be fixed around the frame member (10) by welding to the edge of the groove (113). Here, the welding may be field welding. The hinge joint (114) may hinge the split plates (111, 112) together using a pin, bolt and nut, or rivet, and thereby allow the frame member (10) to be received in the groove (113) while the split plates (111, 112) are spread apart, thereby allowing the frame member (10) to surround the frame member (10).

[0022] The connecting plate (120) is fixed to the edge of the node plate (110) and connected to the truss member (20; see FIG. 7). The connecting plate (120) can be fixed by welding in advance at the factory while being fitted into the node plate (110) by the fitting part (130). The connecting plate (120) can be fixed to the edge of a single node plate (110), which is one example; however, as in the embodiment to be described later, the fixing force can be increased by fixing to the edges of multiple node plates (110). In addition, the connecting plate (120) may be provided with multiple fastening holes (121) for bolting connection with the fixing plate (140) to be described later using a fixing bolt (151) and a fixing nut (152).

[0023] The fitting part (130) allows the node plate (110) and the coupling plate (120) to be fitted together in an intersecting state when fixed. To this end, the fitting part (130) may be formed as a groove structure for fitting into the node plate (110), as in the present embodiment, and the coupling plate (120) may be fitted into the node plate (110) through this groove, but the position may be reversed, or as in subsequent embodiments, grooves for fitting into each other may be formed in both the node plate (110) and the coupling plate (120).

[0024] Referring to FIGS. 6 to 10, the prefabricated truss coupling structure (100) according to the first embodiment of the present invention may further include a fixing plate (140) for fixing to the side of the truss member (20) and a spaced connecting part (160) for spacedly supporting a plurality of node plates (110).

[0025] The fixing plate (140) can be fixed to the end of the truss member (20) and, while in contact with the coupling plate (120), can be fixed by bolting using a fixing bolt (151) and a fixing nut (152) to enable the truss member (20) to be coupled to the coupling plate (120).

[0026] The fixing plate (140) can be fixed via a connecting piece (141) provided at the end of the truss member (20). The connecting piece (141) has the shape of a small disc and is fixed by welding to the end of the truss member (20) so as to be airtight, and the fixing plate (140) can be fixed to the end by welding, but various fixing methods can be applied instead of this welding method.

[0027] The spaced connection portion (160) can connect a plurality of node plates (110) fixed in parallel to the frame member (10) so as to maintain a distance from each other. Accordingly, the load transmitted from the truss member (20) side can be shared by the plurality of node plates (110).

[0028] The spaced connection part (160) can penetrate each of the node plates (110) and each of the split plates (111, 112) with a connecting bolt (161), and the split plates (111, 112) can be supported by a plurality of connecting nuts (162) fastened to the connecting bolt (161). The split plates (111, 112) may be provided with at least one connecting hole (115) for the passage of the connecting bolt (161), and by being supported between the head of the connecting bolt (161) and the connecting nut (162) or between the connecting nuts (162), the node plate (110) can be firmly fixed to another node plate (110) and maintain a predetermined distance from the other node plate (110).

[0029] Referring to FIGS. 11 and 12, as another example, the fixing plate (240) can be fixed via a connecting cone (241) provided at the end of the truss member (20). The connecting cone (241) has a cone shape and can be fixed by welding to the end of the truss member (20) so as to be airtight, and the fixing plate (240) can be fixed by welding while fitting it to the end. However, various fixing methods, including bolting, can be applied instead of this welding method.

[0032] The node plate (310) is fixed to surround the perimeter of the frame member (10) by means of a plurality of split plates (311, 312) connected by a hinge joint, and each of the split plates (311, 312) is formed in a semicircular shape and provided as a pair, each having one end connected to the other by a hinge joint (314), and each of the split plates (311, 312) may have a groove (313) for receiving the frame member (10), and may be fixed to the perimeter of the frame member (10) by welding to the edge of the groove (313).

[0033] The connecting plate (320) is fixed to the edge of the node plate (310) and connected to the side of the truss member (20; see FIG. 19), and a plurality of fastening holes (321) may be formed for bolting connection to be fixed to the fixing plate (340).

[0034] The connecting plate (320) can be simultaneously fitted and fixed to a plurality of node plates (310) that are fixed in parallel to the frame member (10) by means of fitting parts (331, 332). That is, the connecting plate (320) has a configuration different from the previous embodiment, and by being fixed to the edges of the plurality of node plates (310) that are fixed in parallel to the frame member (10), the load applied from itself is distributed to each of the plurality of node plates (310), thereby increasing the fixing force. In this embodiment, the connecting plate (320) can be fixed to two node plates (310). In addition, the connecting plate (320) may be provided with a plurality of fastening holes (321) for bolting connection with the fixing plate (340) to be described later.

[0035] The fitting portions (331, 332) allow the node plate (310) and the coupling plate (320) to be fitted together in an intersecting state when fixed. As in the present embodiment, the node plate (310) and the coupling plate (320) may each be formed with a groove structure for fitting, and the node plate (310) and the coupling plate (320) may be fitted together through this groove.

[0036] Referring to FIGS. 18 to 22, the prefabricated truss coupling structure (300) according to the second embodiment of the present invention may further include a fixing plate (340) for fixing to the side of the truss member (20) and a spaced connecting part (360) for spacedly supporting a plurality of node plates (310).

[0037] The fixing plate (340) is fixed to the end of the truss member (20) and is secured by bolting a fixing bolt (351) and a fixing nut (352) while in contact with the coupling plate (320), thereby enabling the truss member (20) to be coupled to the coupling plate (320).

[0038] The spaced connection portion (360) can connect a plurality of node plates (310) that are fixed in parallel to the frame member (10) so as to maintain a distance from each other. For this purpose, for example, each dividing plate (311, 312) of the node plate (310) can be penetrated by a connecting bolt (361), and the dividing plates (311, 312) can be supported by a plurality of connecting nuts (362) fastened to the connecting bolt (361). The dividing plates (311, 312) may be provided with at least one connecting hole (315) for the passage of the connecting bolt (361).

[0039] According to the prefabricated truss joint structure of the present invention, not only is a significant portion manufactured in advance at the factory, but a node plate having a hinge structure is fixed to the frame member, thereby minimizing assembly and welding work at the site. As a result, construction quality is maintained uniformly without relying heavily on the skill level of the workers, and the number of personnel and time required for construction are minimized, resulting in excellent constructability.
