Description

Technical Field

[0001] This invention relates to the field of steel structure building technology, specifically to a modular steel structure wedge tenon connection node structure. Background Technology

[0002] Prefabricated steel structure buildings are a new type of construction technology characterized by the use of prefabricated steel structure modules, which are assembled on-site. Traditionally, the connection between steel structure modules is mainly by bolts. Bolted connections require a large operating space on-site, and involve a large number of bolts, resulting in high steel and labor costs, low safety, and poor flexibility. The reasons are as follows: 1) The stress distribution between components at bolted connection nodes is complex. Therefore, for safety reasons, more bolts are required in the design of connection nodes. Excessive bolts consume more bolts, increasing steel costs; construction time is also extended, increasing labor costs. 2) Too many bolts at the connection point mean too many holes. Excessive holes lead to stress concentration and uneven stress distribution at the node, resulting in low safety. 3) Bolted connection nodes are difficult to install and disassemble, resulting in poor flexibility. Therefore, there is an urgent need for a connection structure that can securely connect steel structure modules and is easy to assemble and disassemble. Summary of the Invention

[0003] In view of this, the present invention provides a modular steel structure wedge tenon connection node structure to solve the problem of lacking a connection structure that can securely connect steel structure modules and is easy to disassemble and assemble.

[0039] The following is combined Figures 1 to 7 The following describes embodiments of the present invention.

[0040] According to an embodiment of the present invention, a modular steel structure wedge tenon connection node structure is provided for connecting modular steel structures. The modular steel structure includes a first steel structure module 100 and a second steel structure module 200 arranged sequentially along a first direction. A first cross groove 110 is provided in the end of the first steel structure module 100 facing the second steel structure module 200. A first through hole 120 is provided through both side walls of the first steel structure module 100 at the position corresponding to the horizontal part of the first cross groove 110. A second cross groove is provided in the end of the second steel structure module 200 facing the first steel structure module 100. A first through hole 120 is provided through both side walls of the second steel structure module 200 at the position corresponding to the horizontal part of the second cross groove. A second through hole 210 is provided; the wedge tenon connection node structure includes a tenon plate 300, a first tenon 400 and a second tenon 500. The first end of the tenon plate 300 along the first direction is used to insert into the horizontal part of the first cross groove 110, and the second end is used to insert into the horizontal part of the second cross groove; a first connecting hole 310 is provided through the first end sidewall of the tenon plate 300 corresponding to the position of the first through hole 120; a second connecting hole 320 is provided through the second end sidewall of the tenon plate 300 corresponding to the position of the second through hole 210; the first tenon 400 is tenoned to the first through hole 120 and the first connecting hole 310, and the second tenon 500 is tenoned to the second through hole 210 and the second connecting hole 320.

[0041] In this embodiment, the wedge-shaped tenon joint structure has a first through hole 120 and a second through hole 210 respectively provided through the side walls of the first steel structure module 100 and the second steel structure module 200 corresponding to the horizontal parts of the first cross groove 110 and the second cross groove. A first connecting hole 310 and a second connecting hole 320 are respectively provided on the tenon plate 300 at positions corresponding to the first through hole 120 and the second through hole 210. When assembling the first steel structure module 100 and the second steel structure module 200, simply insert the first end of the tenon plate 300 into the horizontal part of the first cross groove 110, aligning the first connecting hole 310 and the first through hole 120. Then, insert the first tenon 400 into the first through hole 120 and the first connecting hole 310 using a tenon-and-mortise connection. Finally, the tenon... The second end of the plate 300 is inserted into the horizontal part of the second "+" groove, so that the second connecting hole 320 and the second through hole 210 are aligned. Finally, the second tenon 500 is inserted into the second through hole 210 and the second connecting hole 320 in a tenon-and-mortise connection manner, so that the first steel structure module 100 and the second steel structure module 200 can be assembled into one unit. The entire assembly process does not require welding or screwing, reducing the labor intensity of workers and saving labor costs. When it is necessary to disassemble the first steel structure module 100 and the second steel structure module 200, it is only necessary to pull out the first tenon 400 from the first through hole 120 and the first connecting hole 310, and pull out the second tenon 500 from the second through hole 210 and the second connecting hole 320 to achieve a non-destructive disconnection. It is easy to disassemble and reuse, and has high flexibility.

[0042] It should be noted that the diameters of the first connecting hole 310, the second connecting hole 320, the first through hole 120, and the second through hole 210 are the same, and the first tenon 400 and the second tenon 500 are the same tenon, reducing the types of components to facilitate procurement and assembly. More specifically, the first steel structure module 100 and the second steel structure module 200 are the same module, and the length of the first tenon 400 is equal to or less than the dimension of the first steel structure module 100 along the second direction, so that after assembly, the first tenon 400 does not protrude from the outer surface of the first steel structure module 100, and the second tenon 500 does not protrude from the outer surface of the second steel structure module 200.

[0043] It is understood that the horizontal portion of the first cross groove 110 and the horizontal portion of the second cross groove are arranged parallel to each other, and the vertical portion of the first cross groove 110 and the vertical portion of the second cross groove are arranged parallel to each other; the first direction mentioned in the text refers to the length direction of the tenon plate 300, the second direction refers to the arrangement direction of the horizontal portion of the first cross groove 110, and the third direction refers to the arrangement direction of the vertical portion of the first cross groove 110. The first direction, the second direction, and the third direction are all perpendicular to each other; for ease of description, this embodiment uses Figure 1The first direction, second direction, and third direction shown are respectively used to describe the length direction of the tenon 300, the horizontal direction of the first cross groove 110, and the vertical direction of the first cross groove 110. However, they should not be construed as explicitly defining the length direction of the tenon 300, the horizontal direction of the first cross groove 110, and the vertical direction of the first cross groove 110.

[0044] In some embodiments, the two side walls of the first steel structure module 100 are provided with third through holes 130 corresponding to the longitudinal part of the first cross groove 110, and the third through holes 130 are used for tenoning the first tenon 400; the two side walls of the second steel structure module 200 are provided with fourth through holes 220 corresponding to the longitudinal part of the second cross groove, and the fourth through holes 220 are used for tenoning the second tenon 500; the first end of the tenon plate 300 is also used to be inserted into the longitudinal part of the first cross groove 110, and the second end of the tenon plate 300 is also used to be inserted into the longitudinal part of the second cross groove. When assembling the first steel structure module 100 and the second steel structure module 200, one can choose to insert the first end and the second end of the tenon plate 300 into the horizontal part of the first cross groove 110 and the horizontal part of the second cross groove respectively, and then use the first tenon nail 400 and the second tenon nail 500 to make a tenon-and-mortise connection. Alternatively, one can choose to insert the first end and the second end of the tenon plate 300 into the vertical part of the first cross groove 110 and the vertical part of the second cross groove respectively, and then use the first tenon nail 400 and the second tenon nail 500 to make a tenon-and-mortise connection. The assembly options are more flexible.

[0045] It is understandable that the third perforation 130 and the first perforation 120 have the same diameter, and the fourth perforation 220 and the second perforation 210 have the same diameter.

[0046] In some embodiments, two of each of the first steel structure module 100 and the second steel structure module 200 are provided.

The tenon plates 300 are provided with a fifth through hole 330 along the length direction of the tenon plates 300. The wedge tenon connection node structure also includes a third tenon 600 arranged parallel to the second direction. The third tenon 600 is used to coaxially tenon the first mounting hole and the fifth through hole 330. During the assembly of the two first steel structure modules 100 and the two second steel structure modules 200, when the first and second ends of the tenon plates 300 arranged in a straight line are respectively inserted into the horizontal parts of the first cross groove 110 and the second cross groove, so that the first connecting hole 310 and the first through hole 120 are aligned and the second connecting hole 320 and the second through hole 210 are aligned, the end faces of the two first steel structure modules 100 and the two second steel structure modules 200 facing each other abut against each other. At this time, the first mounting groove 140 and the second mounting groove 230 surround to form the first mounting hole, and the first mounting... Align the mounting hole with the fifth through hole 330, and then use the third tenon 600 to coaxially insert into the first mounting hole and the fifth through hole 330 of the two tenon plates 300 in a tenon-and-mortise connection, connecting the two tenon plates 300 arranged in a "I" shape into one piece.

[0048] Specifically, each of the first steel structure modules 100 has a third mounting groove 150 extending through its end face facing the second steel structure module 200 along a third direction, and the third mounting groove 150 communicates with the longitudinal part of the first cross groove 110; each of the second steel structure modules 200 has a fourth mounting groove 240 extending through its end face facing the first steel structure module 100 along a third direction, and the fourth mounting groove 240 communicates with the longitudinal part of the second cross groove. The fourth mounting groove 240 and the third mounting groove 150 are correspondingly arranged and enclose to form a second mounting hole; the wedge tenon connection node structure also includes a fourth tenon 700 arranged parallel to the third direction. The fourth tenon 700 is used for coaxial tenoning with the second mounting hole and the fifth through hole 330 of the tenon plate 300 arranged parallel to the third direction, and is also used for coaxial tenoning with the second mounting hole and the sixth through hole 340 of the tenon plate 300 arranged parallel to the second direction. During the assembly of the two first steel structure modules 100 and the two second steel structure modules 200, when the first and second ends of the T-shaped tenon plates 300 are respectively inserted into the first cross groove 110 and the second cross groove, such that the first connecting hole 310 and the first through hole 120 are aligned and the second connecting hole 320 and the fourth through hole 220 are aligned, the end faces of the two first steel structure modules 100 and the two second steel structure modules 200 facing each other abut against each other.

Align the sixth through hole 340 parallel to the second direction, and then use the third tenon 600 to coaxially insert into the first mounting hole, the fifth through hole 330, and the sixth through hole 340 in a mortise and tenon joint manner to connect the two tenon plates 300 arranged in a "T" shape into one unit; then use a fourth tenon 700 to coaxially insert into the second mounting hole and the fifth through hole 330 of the tenon plate 300 arranged parallel to the third direction in a mortise and tenon joint manner, and use another fourth tenon 700 to coaxially insert into the second mounting hole and the sixth through hole 340 of the tenon plate 300 arranged parallel to the second direction in a mortise and tenon joint manner; and cooperate with the first tenon 400 to be inserted into the first through hole 120 and the first connecting hole 310 in a mortise and tenon joint manner, and the second tenon 500 to be inserted into the second through hole 210 and the second connecting hole 320 in a mortise and tenon joint manner, to achieve a more secure assembly connection of the two first steel structure modules 100 and the two second steel structure modules 200 into one unit, and the assembly construction is simple.

[0049] It should be noted that the method of connecting the two first steel structure modules 100 and the two second steel structure modules 200 using the wedge tenon connection node structure of this embodiment only requires a first through hole 120 to be provided through the side wall of the first steel structure module 100 along the second direction, and a first mounting groove 140 to be provided through the first steel structure module 100 along the second direction, and a third mounting groove 150 to be provided through the third direction.

This allows the first steel structure module 100 and the second steel structure module 200 to be connected to the tenon plate 300 through a mortise and tenon joint structure similar to a "+" shape. This reduces the number of openings, thereby reducing stress concentration at the nodes, and also makes the stress distribution more reasonable and the safety higher.

[0050] Specifically, two first steel structure modules 100 arranged sequentially along the second direction are configured as first module components, and two second steel structure modules 200 arranged sequentially along the second direction are configured as second module components. Both the first and second module components are provided in two sets, with the two sets of first module components and the two sets of second module components arranged opposite each other along the first direction. The two sets of first module components are arranged sequentially along a third direction, and the third mounting grooves 150 of the two sets of first module components are aligned along the third direction.

During assembly, the two third tenons 600 are coaxially tenoned to the two first mounting holes and the corresponding fifth through hole 330 and sixth through hole 340, respectively, and the two fourth tenons 700 are coaxially tenoned to the two second mounting holes and the corresponding fifth through hole 330 and sixth through hole 340, respectively. During the assembly of four first steel structure modules 100 and four second steel structure modules 200, two tenon plates 300 arranged in a "T" shape are configured as a set of tenon plate assemblies. When the tenon plates 300 of the two sets of tenon plate assemblies are respectively inserted into the first "+" groove 110 of the corresponding set of first module assemblies and the second "+" groove of the corresponding set of second module assemblies, so that the first connecting hole 310 and the first through hole 120 are aligned and the second connecting hole 320 and the fourth through hole 220 are aligned, the two sets of first The modular component abuts against the opposing end faces of the two sets of second modular components. At this point, the first mounting groove 140 and the second mounting groove 230 enclose to form the first mounting hole, and the third mounting groove 150 and the fourth mounting groove 240 enclose to form the second mounting hole. Initial tenoning is then performed using four first tenons 400 and four second tenons 500, respectively. Subsequently, two third tenons 600 are coaxially inserted into the corresponding first mounting hole, fifth through hole 330, and sixth through hole 340 using a tenon-and-mortise connection. Connect the two tenon plates 300 arranged in a "T" shape in each tenon plate assembly into one piece; then use a fourth tenon 700 to coaxially insert into the corresponding second mounting hole, the fifth through hole 330 of the tenon plate 300 arranged parallel to the third direction, and the sixth through hole 340 of the tenon plate 300 arranged parallel to the second direction using a tenon-and-mortise connection; and use another fourth tenon 700 to coaxially insert into the corresponding second mounting hole and the sixth through hole 340 of the tenon plate 300 arranged parallel to the second direction using a tenon-and-mortise connection. Hole 340 and the fifth through hole 330 of the tenon plate 300 arranged parallel to the third direction connect two adjacent tenon plates 300 along the third direction into a whole; and cooperate with the first tenon 400 to be inserted into the first through hole 120 and the first connecting hole 310 in a mortise and tenon connection, and the second tenon 500 to be inserted into the second through hole 210 and the second connecting hole 320 in a mortise and tenon connection, so as to realize the more secure assembly and connection of the two sets of first module components and the two sets of second module components into a whole, and the assembly construction is simple.

[0051] It should be noted that by using the wedge tenon connection node structure of this embodiment to connect the two sets of first module components and the two sets of second module components, the two third tenons 600 and the two fourth tenons 700 project along the first direction to form a "well" shaped structure, which makes the force distribution more reasonable and the safety higher.

[0052] Specifically, the third tenon 600 includes a separate first part 610 and a second part 620. The first part 610 is disposed on the end face of the second part 620 that is relatively close to the second end of the tenon plate 300 along a first direction, and is connected as a whole by a first locking assembly.

This allows for a more secure assembly and connection of the two sets of first module components and the two sets of second module components into a single unit, simplifying assembly and construction.

[0053] like Figures 3 to 6As shown, specifically, one end of the first part 610 extends beyond the second part 620 along the second direction, and a first protrusion 611 protrudes along the first direction towards the second part 620. The projection of the second part 620 along the second direction overlaps with the first protrusion 611. The first protrusion 611 and the second part 620 are spaced apart along the second direction.

The projection of the third part 710 along the third direction overlaps with the fourth protrusion 721. The fourth protrusion 721 and the third part 710 are spaced apart along the third direction. The end faces of the fourth protrusion 721 and the third part 710 facing each other along the third direction and the end face of the fourth part 720 toward the third part 710 enclose the fourth through groove 740.During the assembly of the four first steel structure modules 100 and the four second steel structure modules 200, the first part 610 and the second part 620 of the two third tenons 600 are first tenoned to their corresponding positions, and then the first through groove 630 and the second through groove 640 are formed respectively at the positions aligned with the two second mounting holes along the third direction. The first locking assembly is then used to lock them together to form a single unit. Subsequently, the third part 710 of one of the fourth tenons 700 is inserted from the first side of the second mounting hole along the third direction and passes through the second through groove 640 of one of the third tenons 600 relatively close to the first side until it abuts against the side wall of the other third tenon 600 along the third direction. Simultaneously, the fourth part 720 of the fourth tenon 700 is inserted from the second side of the second mounting hole along the third direction and passes through the first through groove 640 of one of the third tenons 600 relatively close to the second side. One tenon 630 is inserted into the second mounting hole along the third direction and passes through the second groove 640 of one of the third tenons 600 to abut against the side wall of the other third tenon 600 along the third direction. At this time, it is locked using the second locking component. Then, the third part 710 of the remaining fourth tenon 700 is inserted from the second mounting hole along the second side along the third direction and passes through the second groove 640 of one of the third tenons 600 that is relatively close to the second side to abut against the side wall of the other third tenon 600 along the third direction.

The second locking assembly includes a second locking tenon 750, which is coaxially tenoned to the third mortise and the fourth mortise. During the assembly of the four first steel structure modules 100 and the four second steel structure modules 200, when the third part 710 of the fourth tenon 700 abuts against the side wall of the third tenon 600 which is relatively far from the first side, and the fourth part 720 of the fourth tenon 700 abuts against the side wall of the third tenon 600 which is relatively close to the first side, the third mortise and the fourth mortise are aligned along the first direction. At this time, the second locking tenon 750 is inserted into the third mortise and the fourth mortise in a mortise and tenon connection to complete the locking. The whole process does not require screwing, and the assembly is simple.

[0058] like Figure 7As shown, specifically, a crossbeam 800 is fixed inside the steel structure building.

A reserved opening 811 is provided on the side wall of the installation cavity 810 corresponding to the positions of the first through hole 120 of the first steel structure module 100 and the second through hole 210 of the second steel structure module 200. This allows the reserved opening 811 to be used for tenoning by the first tenon 400 or the second tenon 500 after the first steel structure module 100 and the second steel structure module 200 are fitted into the corresponding installation cavities 810. In specific applications, a limiting strip 820 is provided on the inner side wall of the installation cavity 810, and a limiting groove is provided on the outer side wall of the first steel structure module 100 and the second steel structure module 200 corresponding to the positions of the limiting strip 820.
