[0001] This invention relates to the field of steel structures, and in particular to an extended node structure for steel structure workshops and its usage method. Background Technology

[0002] Steel structures are structures made of steel materials and are one of the main types of building structures. They are mainly composed of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, which are typically connected by welds, bolts, or rivets. Due to their light weight and simple construction, steel structures are widely used in large factories, stadiums, and high-rise buildings.

Preferred embodiments of the invention are shown in the drawings. However, the invention can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to provide a thorough and complete understanding of the disclosure of the invention.

[0025] It should be noted that, unless otherwise defined, all technical and scientific terms used in this specification have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used in this specification is for the purpose of describing particular embodiments only and is not intended to limit the invention. The term "and / or" as used in this specification includes any and all combinations of one or more of the associated listed items.

[0026] like Figures 1 to 8As shown, this invention provides a steel structure factory building expansion node structure. This structure allows for the expansion of factory space without altering the original factory structure, adding multiple independent workshops to meet the needs of increased production scale. The steel structure factory building expansion node structure includes a longitudinal fixed beam 1, transverse side beams 3, and assembly plates 2. The transverse side beams 3 are perpendicular to the longitudinal fixed beam 1 and detachably connected to it. The connection between the longitudinal fixed beam 1 and the transverse side beams 3 forms the roof beam structure of the workshop. The spacing between two adjacent transverse side beams 3 determines the longitudinal length of the workshop. Multiple assembly plates 2 are spaced apart along the axial direction of the transverse side beams 3. The top of each assembly plate 2 is detachably connected to the bottom of the transverse side beams 3. After the assembly plates 2 are installed on the transverse side beams 3, partitions (not shown) are fixed between adjacent assembly plates 2 to form the walls of the workshop. This method allows for the formation of multiple independent workshops.

[0027] Combination Figure 2 and Figure 3 In this embodiment, the longitudinal fixing beam 1 has a concave cross-section and includes a first longitudinal fixing plate 101 and a second longitudinal fixing plate 102 and a third longitudinal fixing plate 103 perpendicular to the first longitudinal fixing plate 101. Multiple sets of fixing holes 104 are provided at intervals on the second longitudinal fixing plate 102 and the third longitudinal fixing plate 103 along the axial direction of the longitudinal fixing beam 1.

[0028] The ends of the transverse side beam 3 are equipped with fixing components, and the transverse side beam 3 is connected to the longitudinal fixed beam 1 through the fixing components. For example... Figure 3 As shown, the fixing assembly includes a mounting clip 23. One end of the mounting clip 23 is fixedly connected to the transverse side beam 3. The other end of the mounting clip 23 is provided with a first connecting groove 24 and a second connecting groove 25 to allow the second longitudinal fixing plate 102 to be inserted into the first connecting groove 24 and the third longitudinal fixing plate 103 to be inserted into the second connecting groove 25. The top of the mounting clip 23 is provided with a first connecting hole 26 that vertically penetrates the first connecting groove 24 and a first fixing bolt 22 to allow the first fixing bolt 22 to pass through the first connecting hole 26 and be threadedly connected to the fixing hole 104 on the second longitudinal fixing plate 102. The bottom of the mounting clip 23 is provided with a second connecting hole (not shown) that vertically penetrates the second connecting groove 25 and a second fixing bolt (not shown) to allow the second fixing bolt to pass through the second connecting hole and be threadedly connected to the fixing hole 104 on the third longitudinal fixing plate 103.

[0029] In this embodiment, when the transverse side beam 3 and the longitudinal fixed beam 1 are installed, the transverse side beam 3 is inserted into a predetermined position in the longitudinal fixed beam 1 through the mounting clip 23. The second longitudinal fixing plate 102 of the longitudinal fixed beam 1 is inserted into the first connecting groove 24 of the mounting clip 23. At this time, the central axis of the first connecting hole 26 on the mounting clip 23 coincides with the central axis of the corresponding fixing hole 104 on the second longitudinal fixing plate 102. The third longitudinal fixing plate 103 of the longitudinal fixed beam 1 is inserted into the second connecting groove 25 of the mounting clip 23. At this time, the central axis of the second connecting hole on the mounting clip 23 coincides with the central axis of the corresponding fixing hole 104 on the third longitudinal fixing plate 103. The first fixing bolt 22 is inserted into the first connecting hole 26 and threadedly connected to the fixing hole 104 on the second longitudinal fixing plate 102. The second fixing bolt is inserted into the second connecting hole and threadedly connected to the fixing hole 104 on the third longitudinal fixing plate 103, so as to realize the connection and fixation of the transverse side beam 3 and the longitudinal fixed beam 1.

[0030] Furthermore, in combination Figures 4 to 7 In this embodiment, the assembly plate 2 is connected to the transverse side beam 3 through the locking mechanism 200. The top of the locking mechanism 200 is detachably connected to the bottom of the transverse side beam 3, and the bottom of the locking mechanism 200 is detachably connected to the assembly plate 2.

[0031] The locking mechanism 200 includes a locking frame 5, a locking block 6, and a vertical fixing post 201. A first groove 202 is provided on the top of the locking frame 5 in the horizontal direction. The vertical fixing post 201 is vertically fixed within the first groove 202. The top of the vertical fixing post 201 is fixedly connected to the locking block 6. Connecting teeth 203 are provided on the side of the locking block 6. Figure 7 The bottom of the transverse side beam 3 is provided with an installation cavity (not shown in the figure), and a fixing block 26 is provided in the installation cavity. A connecting tooth 203 is provided on one side of the fixing block 26 so that the locking block 6 and the fixing block 26 can mesh with each other through the connecting tooth 203.

[0032] exist Figure 7 In the middle, the side wall of the transverse side beam 3 is also provided with a limit adjustment screw 19. One end of the limit adjustment screw 19 exposed on the transverse side beam 3 is connected to the limit adjustment head 20, and the other end of the limit adjustment screw 19 enters the mounting cavity. The fixing block 26 is provided with a limit adjustment screw hole 204 that cooperates with the limit adjustment screw 19, so that the fixing block 26 can move along the longitudinal direction in the mounting cavity when the limit adjustment head 20 rotates.

[0033] In this embodiment, when the locking mechanism 200 is connected to the transverse side beam 3, the locking frame 5 is moved upward so that the locking block 6 enters the mounting cavity of the transverse side beam 3. Then, the limiting adjustment head 20 is rotated so that the fixing block 26 moves in the longitudinal direction of the mounting cavity until the fixing block 26 and the locking block 6 are on the same vertical plane. At this time, the fixing block 26 and the locking block 6 are engaged with each other through the connecting teeth 203, so that the top of the locking mechanism 200 is fixed to the bottom of the transverse side beam 3.

[0034] In this embodiment, there are two locking blocks 6 and two vertical fixing posts 201, which are located at the two ends of the first groove 202 respectively, and the connecting teeth 203 of the two locking blocks 6 are arranged facing each other; two fixing blocks 26 are correspondingly arranged in the mounting cavity. The interlocking of the two locking blocks 6 and the fixing blocks 26 can improve the stability and reliability of the connection between the locking mechanism 200 and the transverse side beam 3.

[0035] Please refer to Figure 6 In some embodiments, the locking mechanism 200 has only one locking block 6, two vertical fixing posts 201 are spaced apart and both are vertically fixed in the first groove 202, the tops of the two vertical fixing posts 201 are fixedly connected to the locking block 6, and the locking block 6 is provided with a locking connection hole 13. The bottom of the transverse side beam 3 is provided with an installation cavity (not shown in the figure), and the side wall of the transverse side beam 3 is also provided with a limit adjustment screw 19. The limit adjustment screw 19 is threadedly connected to the side wall of the transverse side beam 3, and one end of the limit adjustment screw 19 exposed on the transverse side beam 3 is connected to a limit adjustment rotating head 20, and the other end of the limit adjustment screw 19 enters the installation cavity. When the locking mechanism 200 is connected to the transverse side beam 3, the locking frame 5 is moved upward, causing the locking block 6 to enter the mounting cavity of the transverse side beam 3. Then, the limit adjustment head 20 is rotated to connect the limit adjustment screw 19 with the locking connection hole 13, thereby achieving a detachable connection between the top of the locking mechanism 200 and the transverse side beam 3. Apart from the differences described above, the other components of the locking mechanism 200 in these embodiments are the same as those of the locking mechanism 200 shown in other embodiments of this application.

[0036] Combination Figure 5In this embodiment, the bottom of the first groove 202 is also provided with a first adjustment hole 14, which vertically penetrates the locking frame 5; the side wall of the locking frame 5 is also provided with a first through hole 206 that longitudinally penetrates the locking frame 5, which is connected to the first adjustment hole 14, and a locking adjustment screw 16 is inserted in the first through hole 206. One end of the locking adjustment screw 16 is provided with an adjustment wheel 7, so that the locking adjustment screw 16 can rotate coaxially when the adjustment wheel 7 is rotated; a rotating wheel 17 is provided near the adjustment wheel 7 of the locking adjustment screw 16, and the side wall of the locking frame 5 is also provided with a rotating hole 15 that matches the rotating wheel 17. The rotating hole 15 coincides with the central axis of the first through hole 206, and the diameter of the rotating hole 15 is larger than the diameter of the first through hole 206, so that the locking adjustment screw 16 will not move axially in the longitudinal direction of the locking frame 5 during rotation.

[0037] The other end of the locking adjusting screw 16 is provided with a stop part 25, which is located on the other side of the locking frame 5 relative to the adjusting wheel 7, to prevent the locking adjusting screw 16 from disengaging from the first through hole 206.

[0038] Furthermore, in Figure 4 In the locking mechanism 200, a locking assembly is also included. The bottom of the locking frame 5 is detachably connected to the mounting plate 2 via the locking assembly. The locking assembly includes a first locking clamping block 8 and a second locking clamping block 9. The tops of the first locking clamping block 8 and the second locking clamping block 9 are housed in the first adjusting hole 14 and connected to the locking adjusting screw 16, allowing the first locking clamping block 8 and the second locking clamping block 9 to move away from or closer to each other when the locking adjusting screw 16 rotates. A first limiting post 207 and a second limiting post 208 are respectively provided on the inner sides of the first locking clamping block 8 and the second locking clamping block 9 facing each other. A mounting hole 209 is correspondingly provided on the top of the mounting plate 2, allowing the first limiting post 207 and the second limiting post 208 to pass through the mounting hole 209.

[0039] In this embodiment, the locking adjusting screw 16 has an external thread in the axial direction divided into a first external thread portion and a second external thread portion. The threads of the first external thread portion and the second external thread portion are opposite to each other. The first external thread portion is threadedly connected to the first locking clamping block 8, and the second external thread portion is threadedly connected to the second locking clamping block 9, so that when the locking adjusting screw 16 rotates, the first locking clamping block 8 and the second locking clamping block 9 can move away from or closer to each other. When installing the assembly plate 2, the assembly hole 209 of the assembly plate 2 is aligned with the first limiting post 207 and the second limiting post 208. Then, the locking adjusting screw 16 is rotated by the adjusting wheel 7, so that the first locking clamping block 8 and the second locking clamping block 9 can move closer to each other. The first limiting post 207 and the second limiting post 208 are inserted into the assembly hole 209, thereby fixing the assembly plate 2.

[0040] In some embodiments, one of the first locking clamping block 8 and the second locking clamping block 9 is fixed within the first adjusting hole 14, and the locking adjusting screw 16 passes through either the first locking clamping block 8 or the second locking clamping block 9. The other of the first locking clamping block 8 and the second locking clamping block 9 is threadedly connected to the locking adjusting screw 16, so that when the locking adjusting screw 16 rotates, the first locking clamping block 8 and the second locking clamping block 9 can move away from or closer to each other. When installing the assembly plate 2, the assembly hole 209 of the assembly plate 2 is aligned with the first limiting post 207 and the second limiting post 208, and then the locking adjusting screw 16 is rotated by the adjusting wheel 7, so that the first locking clamping block 8 and the second locking clamping block 9 can move closer to each other. The first limiting post 207 and the second limiting post 208 are inserted into the assembly hole 209, thereby fixing the assembly plate 2.

[0041] In this embodiment, there are two first adjustment holes 14, distributed at both ends of the bottom of the first groove 202 along the transverse direction of the locking frame 5, and a locking component is connected to each first adjustment hole 14. A first connecting rod 30 is also provided between the two first locking clamping blocks 8, and multiple first auxiliary locking clamping blocks 10 are connected to the first connecting rod 30 along the transverse direction. A second connecting rod 40 is also provided between the two second locking clamping blocks 9, and multiple second auxiliary locking clamping blocks 11 are connected to the second connecting rod 40 along the transverse direction. A first limiting post 207 and a second limiting post 208 are respectively provided on the facing inner sides of the first auxiliary locking clamping blocks 10 and the second auxiliary locking clamping blocks 11. A protruding transverse mounting portion 18 is provided on the top of the mounting plate 2, and multiple mounting holes 209 are evenly distributed along the transverse mounting portion 18.

[0042] In this embodiment, there are 2 to 3 first auxiliary locking blocks 10 and second auxiliary locking blocks 11. As the first locking blocks 8 and 9 approach each other, the first connecting rod 30 and the second connecting rod 40 pull the first auxiliary locking blocks 10 and 11 closer together, causing the first limiting post 207 on the first auxiliary locking block 10 and the second limiting post 208 on the second auxiliary locking block 11 to simultaneously insert into the corresponding mounting holes 209 on the mounting plate 2, thereby enhancing the stability and reliability of the connection between the locking mechanism 200 and the mounting plate 2.

[0043] Furthermore, such as Figure 9 As shown, the present invention also provides a method for using an extended node structure in a steel structure factory building, comprising the following steps:

[0044] Step S1: Insert multiple transverse side beams 3 onto the longitudinal fixed beam 1 using mounting clips 23, adjust the spacing between two adjacent transverse side beams 3, and then fix the mounting clips 23 to the longitudinal fixed beam 1.

[0045] Step 2 S2: Install the locking mechanism at the bottom of the transverse side beam 3;

[0046] Step 3 S3: Fix the assembly plate 2 by locking mechanism. There are multiple assembly plates 2, which are spaced apart along the axial direction of the transverse side beam 3.

[0047] Step 4S4: Fix the partition between two adjacent assembly plates 2 to form the factory wall.

[0048] This invention discloses an expansion node structure for a steel structure factory building, including longitudinal fixed beams, transverse side beams, and assembly plates. The transverse side beams are perpendicular to the longitudinal fixed beams and detachably connected to them. After the longitudinal fixed beams and transverse side beams are connected and fixed, they form the roof structure of the factory building. The spacing between two adjacent transverse side beams determines the longitudinal length of the factory building. Multiple assembly plates are spaced apart along the axial direction of the transverse side beams. The top of each assembly plate is detachably connected to the bottom of the transverse side beams. After the assembly plates are installed on the transverse side beams, partitions are fixed between adjacent assembly plates to form the walls of the factory building. This steel structure factory building expansion node structure can expand the factory building space and add multiple independent workshops without changing the original factory building structure, thus meeting the needs of expanding the factory's production scale.

[0049] The above are merely embodiments of the present invention and do not limit the patent scope of the present invention. Any equivalent structural transformations made based on the content of the present invention specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of the present invention.
