Steel node and manufacturing method

Abstract

The present invention discloses a steel node and a manufacturing method. The steel node includes a node body and a main corbel. The node body includes two node plates and multiple inner baffles. Each node plate includes a corbel flange plate and multiple column flange plates arranged along a preset direction. The multiple inner baffles are arranged between the two node plates. Each column flange plate is welded to the inner baffle, and each inner baffle is welded to the column flange plates on opposite sides of the inner baffle. When welding the node body, workers can weld each column flange plate to the inner baffle in sequence along a preset direction to gradually form a column portion. Since the volume of the column flange plate is smaller than that of the node plate as a whole, the distance between the weld points between the column flange plates and the outside world is reduced, which increases the operating space of workers during welding, so that the welding between the column flange plate and the inner baffle can meet the welding requirements of full penetration.

The connections between the partitions and between the partitions and gusset plates require full penetration welding to ensure the strength of the multi-cavity steel node. However, due to the small space between the two gusset plates, the welding operation is difficult and cannot guarantee the required full penetration welding. Summary of the Invention

[0057] Reference below Figures 1 to 13 The steel node and the manufacturing method of the present invention are described in detail.

[0058] Reference Figure 1 and Figure 6 A steel node according to an embodiment of the present invention includes a node body 100 and a main corbel 200 .

[0059] The node body 100 includes two node plates 110 and multiple inner baffles. Each node plate 110 includes a corbel flange plate 114 and multiple column flange plates arranged along a preset direction. Multiple inner baffles are arranged between the two node plates 110. Each column flange plate is welded to the inner baffle, and each inner baffle is welded to the column flange plates on opposite sides of the inner baffle. The corbel flange plate 114 is welded to the column flange plate located on the upper side of the node plate 110; the node plate 110 is welded to the main corbel 200.

[0060] For example, Figure 1 and Figure 6As shown, the node body 100 includes two node plates 110 and a plurality of inner baffles, wherein the plurality of inner baffles are arranged between the two node plates 110; the node plate 110 includes a plurality of column flange plates connected in sequence in the vertical direction, adjacent column flange plates are welded to each other, and each inner baffle is welded to the column flange plates on both sides of the inner baffle; the node plate 110 also includes a corbel flange plate 114, which is welded to the uppermost column flange plate. Since the node plate 110 of the steel node of the present application includes a plurality of column flange plates connected in sequence in the vertical direction, when welding the node body 100, the column flange plates can be welded to the inner baffles in sequence from bottom to top. The column flange plates are smaller in size than the node plates 110, which reduces the distance between the welding points between the column flange plates and the outside world, increases the operating space of the workers during welding, and enables the welding between the column flange plates and the inner baffles to meet the requirement of full penetration.

[0061] Specifically, refer to Figure 2 and Figure 3 The node body 100 may include three column flange plates and a corbel flange plate 114. The three column flange plates are respectively a first column flange plate 111, a second column flange plate 112, and a third column flange plate 113. The first column flange plate 111, the second column flange plate 112, and the third column flange plate 113 are welded together from bottom to top, and the corbel flange plate 114 is welded to the upper edge of the third column flange plate 113. The first column flange plate 111, the second column flange plate 112, the third column flange plate 113, and the corbel flange plate 114 are distributed in the vertical direction. While ensuring full penetration welding between each column flange plate and the inner diaphragm, it can ensure that the longitudinal shear force borne by the node body 100 meets the requirements.

[0062] In some embodiments of the present invention, the main corbel 200 includes two corbel structures 210 and a transverse connecting structure 220. The transverse connecting structure 220 is respectively connected to the two corbel structures 210. The two corbel structures 210 are respectively welded to the two gusset plates 110. For example, Figure 1 As shown, the main corbel 200 includes two corbel structures 210 and a transverse connecting structure 220. The upper ends of the two corbel structures 210 are welded to the outer sidewalls of the two gusset plates 110. The lower ends of the two corbel structures 210 are connected by a transverse connecting structure 220, and the upper end surfaces of the transverse connecting structures 220 are welded to the lower end surfaces of the two gusset plates 110. Furthermore, when the steel joint is used in a building, the force borne by the steel joint can be transmitted to the supporting structure below through the main corbel 200.

[0063] Specifically, the bracket structure 210 includes a composite plate 212, a horizontal flange plate 211 and a longitudinal flange plate 213. The composite plate 212 is connected to the node plate 110. The horizontal flange plate 211 is connected to the node plate 110 and is passed through the composite plate 212. The longitudinal flange plate 213 is connected to the horizontal flange plate 211 and the composite plate 212 respectively. The transverse connection structure 220 includes a transverse stiffener 221 and a connecting flange plate 222. The connecting flange plate 222 is connected to the two longitudinal flange plates 213 respectively. The transverse stiffener 221 is connected to the node body 100 and the connecting flange plate 222 respectively. For example, Figure 1 As shown, the bracket structure 210 includes a composite plate 212, two horizontal flange plates 211 and two groups of longitudinal flange plates 213. Each group of longitudinal flange plates 213 can include two longitudinal flange plates 213. The composite plate 212 is welded to the outer wall of the node plate 110. Two mounting holes are provided on the composite plate 212. The two horizontal flange plates 211 pass through the mounting holes respectively and are welded to the node plate 110. The two horizontal flange plates 211 are distributed up and down. The lower horizontal flange plate 211 is also provided with two through holes distributed left and right. The two groups of longitudinal flange plates 213 are respectively passed through the two through holes, and the two groups The upper ends of the longitudinal flange plates 213 are connected to the upper horizontal flange plates 211. The transverse connecting structure 220 includes a transverse stiffener 221 and two connecting flange plates 222, which are distributed on the left and right sides and have mounting slots on their upper ends. The upper end faces of the transverse stiffeners 221 are welded to the lower end faces of the gusset plates 110. The connecting flange plates 222 are welded to the lower ends of the left and right longitudinal flange plates 213, respectively. Through-holes are formed between the groove walls of the mounting slots of the connecting flange plates 222 and the lower end faces of the gusset plates 110, and the transverse stiffeners 221 are inserted into the through-holes. Thus, the forces acting on the node body 100 can be transmitted to the connecting flange plates 222 through the horizontal flange plates 211 and the longitudinal flange plates 213 in sequence. The lower ends of the connecting flange plates 222 can be connected to the load-bearing structure to transmit the forces acting on the connecting flange plates 222 to the load-bearing structure.

[0064] Reference Figure 7 The method for manufacturing a steel node according to the second aspect of the present invention includes but is not limited to the following steps:

[0065] Step S100: welding a plurality of column flange plates to the inner partition plate in sequence along a preset direction to form a column portion of the node body 100;

[0066] It is understood that the column portion can include two sets of column flange plates, each set of column flange plates comprising a plurality of column flange plates arranged vertically, with a plurality of inner baffles disposed between the two sets of column flange plates, each inner baffle being welded to the two column flange plates on opposite sides thereof. The volume of the column flange plates is relatively small compared to the volume of the entire gusset plate 110. When welding the column flange plates to the inner baffles, and between the inner baffles, the distance between the weld points and the outside world is reduced, thereby increasing the operator's operating space during welding and thereby achieving the requirement for full penetration welding within the column portion.

[0067] Step S200: welding the corbel flange plates 114 to the two column flange plates on the upper side edge of the column portion to form the node body 100;

[0068] It is understandable that when the steel node of the present application is used, the corbel flange plate 114 needs to be connected to the building structure above the steel node to support the building structure above.

[0069] Step S300: welding the main corbel 200 to the node body 100 to form a steel node.

[0070] It is understandable that when the steel node of the present application is used, the main corbel 200 can be connected to the bearing structure below the steel node, so that the pressure applied to the steel node by the upper building structure can be dispersed to the bearing structure.

[0071] In some embodiments of the present invention, reference Figure 6 and Figure 8 The plurality of column flange plates include two first column flange plates 111, two second column flange plates 112, and two third column flange plates 113. Step S100 includes but is not limited to the following steps:

[0072] Step S110: welding the two first column flange plates 111 to the plurality of inner partition plates installed between the two first column flange plates 111;

[0073] Step S120: Welding the two second column flange plates 112 to the upper edges of the two first column flange plates 111, and welding the two second column flange plates 112 to the inner partition plate located between the two second column flange plates 112.

[0074] Step S130: Weld the two third column flange plates 113 to the upper edges of the two second column flange plates 112 respectively, and weld the two third column flange plates 113 to the inner partition plate installed between the two third column flange plates 113 to form a column portion.

[0075] It can be understood that in the process of welding to form the column part, the first column flange plate 111, the second column flange plate 112 and the third column flange plate 113 are welded to the inner partition plate from bottom to top in sequence. The volume of a single first column flange plate 111, the second column flange plate 112 and the third column flange plate 113 are all smaller than the node plate 110, so that the welding gun can be extended between the two first column flange plates 111, between the two second column flange plates 112 or between the two third column flange plates 113 to complete the welding operation, thereby ensuring the operating space of the staff during welding, and thus being able to achieve the welding requirement of full penetration in the column part.

[0076] Further, in some embodiments of the present invention, reference Figure 4 and Figure 9 The plurality of inner baffles include a plurality of longitudinal baffles 140, a plurality of first webs 150, and a plurality of first transverse baffles 120. Step S110 includes but is not limited to the following steps:

[0077] Step S111: welding the first webs 150 one by one to the lower ends of the two first column flange plates 111 , and when each first web 150 is welded, welding the corresponding longitudinal partition 140 above the first web 150 ;

[0078] It is understood that a plurality of first webs 150 are welded to the lower ends of the two first column flange plates 111, and a longitudinal baffle 140 can be welded to the upper ends of the first webs 150. The portions of the longitudinal baffles 140 located between the two first column flange plates 111 need to be welded to the two first column flange plates 111, respectively. After each first web 150 is welded, the corresponding longitudinal baffle 140 above the first web 150 is welded, and then the gap between the longitudinal baffle 140 and the first web 150 is welded. The worker can use a welding torch to weld from the lower end of the first column flange plate 111, thus avoiding the problem of limited operating space when welding the gap between the longitudinal baffle 140 and the first web 150 from the upper end of the first column flange plate 111, thereby ensuring the full penetration welding requirement when welding the first web 150 and the longitudinal baffle 140.

[0079] Furthermore, in order to improve the ability of the first column flange plate 111 to resist longitudinal shear force, part of the longitudinal partition 140 is welded at the corner of the length direction of the first column flange plate 111; the ability of the first column flange plate 111 to withstand longitudinal shear force at the corner is weak and prone to breakage. By welding the longitudinal partition 140 at the corner of the first column flange plate 111, the strength of the first column flange plate 111 at the corner can be improved.

[0080] Step S112 : welding a plurality of first transverse partitions 120 located between the two first column flange plates 111 , so that the first transverse partitions 120 are respectively welded to the two first column flange plates 111 and part of the longitudinal partitions 140 .

[0081] It can be understood that by welding multiple first transverse partitions 120 between two first column flange plates 111, the first transverse partitions 120 can improve the ability of the node body 100 to resist longitudinal shear force. At the same time, the first transverse partitions 120 can connect part of the longitudinal partitions 140, thereby improving the installation strength of the longitudinal partitions 140.

[0082] In some embodiments of the present invention, reference Figure 5 and Figure 10 The plurality of inner partitions further include a plurality of second transverse partitions 130. Step S120 includes but is not limited to the following steps:

[0083] Step S121: Welding the two second column flange plates 112 to the upper edges of the two first column flange plates 111, and welding the longitudinal partition plate 140 extending between the two second column flange plates 112 to the two second column flange plates 112.

[0084] It is understandable that by welding the longitudinal partition plate 140 extending between the two second column flange plates 112 to the two second column flange plates 112 respectively, the connection strength between the first column flange plate 111 and the second column flange plate 112 can be improved.

[0085] Step S122 : Welding the second transverse partition plate 130 installed between the two second column flange plates 112 to the two second column flange plates 112 respectively.

[0086] It can be understood that the second transverse partition 130 can improve the longitudinal shear resistance of the second column flange plate 112 , thereby improving the strength of the node body 100 .

[0087] In some embodiments of the present invention, reference Figure 6 and Figure 11 The plurality of inner baffles further include a plurality of second webs 160. Step S130 includes but is not limited to the following steps:

[0088] Step S131: Welding the two third column flange plates 113 to the upper edges of the two second column flange plates 112, and welding the longitudinal partition plate 140 extending between the two third column flange plates 113 to the two third column flange plates 113;

[0089] It can be understood that by welding the longitudinal partition 140 extending between the two third column flange plates 113 to the two third column flange plates 113 respectively, the connection strength between the third column flange plates 113, the second column flange plates 112 and the first column flange plates 111 can be improved, thereby improving the strength of the node body 100.

[0090] Step S132: Welding a plurality of second transverse partitions 130 between the two third column flange plates 113 so that the second transverse partitions 130 are respectively welded to the two second column flange plates 112 and a portion of the longitudinal partitions 140;

[0091] It can be understood that multiple second transverse partitions 130 can be installed in the middle of the length direction of the second column flange plate 112. By welding multiple second transverse partitions 130 between two third column flange plates 113, the second transverse partitions 130 can improve the longitudinal shear resistance of the third column flange plate 113.

[0092] Step S133 : welding a plurality of second web plates 160 between two third column flange plates 113 to form a column portion.

[0093] It can be understood that the second web 160 is welded to the upper ends of the two third column flange plates 113. By setting the second web 160, the second web 160 can improve the overall strength of the node body 100. At the same time, the second web 160 can protect the longitudinal partition 140 and the second transverse partition 130 between the third column flange plates 113.

[0094] In some embodiments of the present invention, reference Figure 1 and Figure 12 The main corbel 200 includes a transverse connecting structure 220 and two corbel structures 210. Step S300 includes but is not limited to the following steps:

[0095] Step S310: welding the corbel structures 210 to the two gusset plates 110 respectively;

[0096] Step S320 : welding the transverse connection structure 220 between the two corbel structures 210 to form a main corbel 200 .

[0097] Understandably, the reference Figure 1The transverse connecting structure 220 includes a transverse stiffener 221 and a connecting flange plate 222. The two sides of the connecting flange plate 222 are respectively welded to the longitudinal flange plates 213 of the two corbel structures 210. The transverse stiffener 221 is inserted into the through hole between the connecting flange plate 222 and the gusset plate 110, and the transverse stiffener 221 is respectively welded to the gusset plate 110 and the connecting flange plate 222. When installing the transverse connecting structure 220, the upper side of the transverse stiffener 221 is first welded to the lower side of the two gusset plates 110. Then, the middle portion of the upper side of the connecting flange plate 22 is abutted against the transverse stiffener 221, and the two sides of the connecting flange plate 222 are respectively welded to the longitudinal flange plates 213 of the two corbel structures 210.

[0098] Optional, reference Figure 1 There may be multiple connecting flange plates 222 . In this case, a corbel web 230 is welded between adjacent connecting flange plates 222 to enhance the stability of the connecting flange plates 222 .

[0099] Specifically, refer to Figure 1 and Figure 13 The corbel structure 210 includes a plurality of horizontal flange plates 211, two laminated plates 212, and a plurality of longitudinal flange plates 213. Step S310 includes but is not limited to the following steps:

[0100] Step S311: welding and connecting a plurality of horizontal flange plates 211 to the gusset plate 110;

[0101] It can be understood that the corbel structure 210 can include two horizontal flange plates 211, which are welded to the outer wall of the node plate 110 and distributed up and down. Furthermore, when the node body 100 is subjected to force, the force exerted on the node body 100 can be dispersed to the main corbel 200 through the horizontal flange plates 211; at the same time, the provision of the horizontal flange plates 211 can increase the longitudinal shear force exerted on the main corbel 200.

[0102] Step S312: welding the composite plate 212 to the gusset plate 110 , and passing the horizontal flange plate 211 through the composite plate 212 ;

[0103] Understandably, the reference Figure 1 The composite plate 212 is attached to the gusset plate 110 and is welded to the gusset plate 110 , so that the composite plate 212 can improve the strength of the gusset plate 110 .

[0104] Step S313 : Install the longitudinal flange plate 213 on the horizontal flange plate 211 , and weld the horizontal flange plate 211 and the longitudinal flange plate 213 together.

[0105] Understandably, the reference Figure 1The corbel structure 210 can include two groups of longitudinal flange plates 213 distributed in the left and right directions. Each group of longitudinal flange plates 213 is passed through the lower horizontal flange plate 211 and is welded to the lower end of the upper horizontal flange plate 211. Therefore, the force exerted on the horizontal flange plate 211 can be dispersed to the longitudinal flange plate 213; at the same time, the setting of the longitudinal flange plate 213 can increase the lateral shear force exerted on the main corbel 200.

[0106] In some embodiments of the present invention, reference Figure 1 and Figure 7 After step S300, the following steps are also included but not limited to:

[0107] Step S400: Welding and connecting the external component plate 300 to the steel node.

[0108] It is understandable that the connection structure on the steel node is limited. During the use of the steel node, when the connection structure on the steel node cannot meet the use requirements, the number of building structures connected to the steel node can be increased by welding the external part plate 300 on the steel connection point.

[0109] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to the embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the claims and their equivalents.
