Description

Technical Field

[0001] The invention relates to the field of steel structure assembly, and in particular to a green building steel structure. Background Art

[0002] Green building steel structure is an environmentally friendly steel structure system widely used in the construction industry. Green building steel structure is highly favored due to its many advantages such as high space utilization and excellent seismic resistance. Especially in the trend of pursuing low-carbon and environmentally friendly buildings, the application scope of green steel structure is constantly expanding.

[0003] Among various application fields, container assembly in construction site is particularly prominent, mainly due to its fast construction speed, high flexibility and more reuse of resources. Container assembly has become one of the most common forms of green building steel structures on construction sites.

[0004] During the container assembly process, the connection between the base and the bottom plate is usually done manually, using bolts and nuts to lock and fix the steel to the two bases, and then connecting the bottom plate and the steel with self-tapping screws. Although this method can provide good connection effects in the short term, during the long-term use of the container, factors such as vibration may cause the bolt and nut connection to loosen, which in turn causes loosening and abnormal noise between the bottom plate, base and steel. In addition, when manually connecting the bottom plate, steel and base, in order to ensure the connection strength, it is usually necessary to fix them at multiple points. In the assembly work involving multiple containers, the efficiency of this traditional connection method needs to be improved. Summary of the invention

[0037] The following is combined with the attached Figure 1-15 This application is further described in detail.

[0038] Please refer to Figure 1 A green building steel structure includes an L-shaped base 1. Two L-shaped bases 1 are provided and are symmetrical in the front-to-back direction. A supporting mechanism 2 is slidably installed on the upper end surface of the L-shaped base 1.

[0039] Please refer to Figure 1 , Figure 2 , Figure 5 and Figure 8 The supporting mechanism 2 includes two supporting plates 21 arranged in a cross manner between the two L-shaped bases 1, a linkage groove is commonly opened at the center position of the two supporting plates 21, and four locking grooves 212 are opened in the inner wall of the linkage groove in a circumferential direction. Both ends of the two supporting plates 21 are fixedly provided with a mounting shell 22, and the interior of the mounting shell 22 is provided with an inner support portion 23 for locking the inner support of the L-shaped base 1. The intersection of the two supporting plates 21 is commonly provided with a fixing portion 24 for limiting the rotation of the two supporting plates 21, and a bottom plate 3 is commonly placed on the inner support portion 23 and the fixing portion 24. The bottom plate 3 is also provided with a locking mechanism 4 for cooperating with the supporting mechanism 2 for locking.

[0040] Please refer to Figure 4 and Figure 5 The locking mechanism 4 includes a locking portion 41 for locking the two supporting plates 21, and a driving portion 42 for driving the locking portion 41 to rotate is also provided on the bottom plate 3.

[0041] When manually connecting the bottom plate 3 and the L-shaped base 1, the worker first places the supporting plate 21 and the mounting shell 22 between the two L-shaped bases 1, and then adjusts the distance between the two L-shaped bases 1 according to work requirements and changes the angle between the two supporting plates 21. After the position adjustment is completed, the fixing part 24 is manually controlled to be inserted into the two supporting plates 21 synchronously to complete the limiting work of the two supporting plates 21 to ensure that they will not deviate or shake.

[0042] Then, the base plate 3 is manually placed on the mounting shell 22 and the supporting plate 21, and the locking portion 41 is driven to rotate by the driving portion 42 to realize the clamping and fixing of the locking portion 41 to the supporting plate 21, thereby completing the limiting work of the base plate 3 and the supporting plate 21 to ensure that the base plate 3 and the supporting plate 21 are connected as a whole.

[0043] At the same time, when the bottom plate 3 and the supporting plate 21 are connected into a whole through the locking portion 41, the locking portion 41 cooperates with the inner support portion 23 to respectively complete the inner support fixation of the bottom plate 3 and the L-shaped base 1, thereby further improving the connection strength between the bottom plate 3 and the L-shaped base 1, and avoiding problems such as abnormal noise at the connection when the bottom plate 3 is used for too long.

[0044] Please refer to Figure 1 and Figure 2 The L-shaped base 1 is divided into a horizontal section for support and a vertical section for limitation. On the upper end surface of the horizontal section, a first mating groove 11 is formed in the left-right direction. On one side wall of the vertical section close to the first mating groove 11, two mounting grooves 12 are formed and distributed in the left-right direction. The tops of the two mounting grooves 12 are open. On one side wall of the vertical section close to the first mating groove 11, a sliding groove 13 communicating with the two mounting grooves 12 is also formed in the left-right direction.

[0045] Please refer to Figure 2 On the upper end surface of the supporting plate 21, two diamond-shaped grooves 211 are formed along its arrangement direction. The mounting shells 22 fixedly arranged at both ends of the supporting plate 21 respectively slide inside the corresponding first mating grooves 11.

[0046] Please refer to Figure 3 、 Fig. 9 、 Fig.10 、 Fig.11 and Fig.12 The fixing part 24 includes a circular column 241 fixedly arranged on the lower end surfaces of the two supporting plates 21 and having a circular groove formed at the center. A limiting groove 2411 is formed inside the circular groove. A circular plate 242 for increasing the contact area with the ground is fixedly arranged on the lower end surface of the circular column 241. Inside the circular groove, a tapered plug 243 with a gradually increasing taper from bottom to top is fixedly arranged through a spring telescopic sleeve. An inverted U-shaped handle 244 with an opening facing down is fixedly arranged on the upper end surface of the tapered plug 243. A strip-shaped block 245 is fixedly arranged on the outer wall of the tapered plug 243. The fixing part 24 further includes an annular ring 246 sleeved on the outer wall of the tapered plug 243 and fixedly connected to the upper end surface of the circular column 241. Both the annular ring 246 and the tapered plug 243 are located inside the linkage groove. Avoidance through grooves 2461 are formed on the outer wall of the annular ring 246 corresponding to the four locking grooves 212. Locking blocks 247 in contact with the outer wall of the tapered plug 243 are slidably arranged inside the four avoidance through grooves 2461. A sliding groove 2462 is also formed on the inner wall of the annular ring 246 corresponding to the strip-shaped block 245.

[0047] During specific operation, first, manually slide two supporting plates 21 and the mounting housing 22 provided thereon into the L-shaped base 1 along the mounting groove 12. At this time, after the mounting housing 22 slides into the L-shaped base 1, its side wall is clamped into the sliding groove 13, and the lower end of the mounting housing 22 is clamped into the first mating groove 11. At the same time, the circular plate 242 is in contact with the ground. Subsequently, adjust the distance between the two L-shaped bases 1 and the included angle between the two supporting plates 21 according to the installation requirements. After adjusting to the specified position, the worker presses down the tapered plug 243 and the strip-shaped block 245 provided on the tapered plug 243 through the U-shaped handle 244. At this time, the four locking blocks 247 inside the annular ring 246 are synchronously expanded outward by the pushing of the tapered plug 243 and move into the locking groove 212. When the tapered plug 243 is pressed down to a certain position and the height of the tapered plug 243 is the same as the height of the two supporting plates 21, manually rotate the tapered plug 243 and make the strip-shaped block 245 rotate into the limiting groove 2411 in the circular groove. At this time, the strip-shaped block 245 of the tapered plug 243 is clamped into the limiting groove 2411 and cannot be reset. Thus, the locking and limiting work of the two supporting plates 21 is completed.

A folded line push plate 223 is slidably arranged inside the mounting housing 22, and the upper and lower end surfaces of the side wall of the folded line push plate 223 away from the supporting plate 21 are both inclined surfaces.

[0050] Please refer to Figure 5 and Figure 6The locking portion 41 includes an annular plate 411 that is rotatably arranged inside the annular groove by a roller shaft (not shown in the drawings), and the inner side wall of the annular plate 411 is provided with a plurality of rectangular grooves along its circumferential direction, and the end surface of the annular plate 411 is also provided with four arc-shaped slide grooves 4111 along the circumferential direction, and the four arc-shaped slide grooves 4111 penetrate the annular plate 411 upward, and the locking portion 41 also includes a rhombus top block 412 arranged below the four arc-shaped slide grooves 4111, and the rhombus top blocks 412 are provided with four corresponding rhombus grooves 211 and are located in the corresponding rhombus grooves 211, and the upper end surface of the rhombus top block 412 is fixedly provided with a linkage rod 413 that is always located inside the arc-shaped slide groove 4111 and is slidably connected to the lower surface of the bottom plate 3.

[0051] Please refer to Figure 4 and Figure 6 The driving part 42 includes a ratchet 421 which is rotatably arranged inside the circular groove 31 and has three hexagonal grooves 4211 on its end face. The lower end face of the ratchet 421 rotates through the bottom plate 3 and is located inside the bottom plate 3 with a driving disk 422 which is rotatably arranged. The outer wall of the driving disk 422 is fixedly provided with linkage blocks 423 corresponding to several rectangular grooves. Several linkage blocks 423 are always located inside the corresponding rectangular grooves. The driving part 42 also includes a pawl 424 which is installed inside the circular groove 31 through a spring and contacts the ratchet 421.

[0052] Please refer to Fig.13 , Fig.14 and Fig.15 The inner support portion 23 includes a rectangular shell 231 fixedly arranged inside the mounting groove in a vertically symmetrical manner, and an inverted L-shaped support block 232 is slidably arranged inside the rectangular shell 231 in a front-to-back symmetrical manner. The side walls of the two inverted L-shaped support blocks 232 are fixedly connected to the inner walls of the corresponding rectangular shell 231 through springs. The inverted L-shaped support block 232 is divided into a vertical matching section and a horizontal rubber pressing section. The rubber pressing sections of the two inverted L-shaped support blocks 232 respectively penetrate the side walls of the corresponding rectangular shell 231, and the side where the matching sections of the two inverted L-shaped support blocks 232 are close to each other is set as an inclined surface. The inner support portion 23 also includes a triangular top plate 233 slidably arranged inside the rectangular shell 231 and in conflict with the two inclined surfaces of the matching section.

[0053] After the two supporting plates 21 are locked and limited, the worker places the bottom plate 3 on the supporting plates 21, and makes the rectangular shell 231 located in the matching groove 233 on the lower end surface of the bottom plate 3, and the four rhombus top blocks 412 at the lower end of the bottom plate 3 are respectively located in the corresponding rhombus grooves 211, and then through the tool (such as the attached Figure 4 As shown in the figure, the ratchet wheel 421 and the driving disk 422 are driven to rotate. When the driving disk 422 rotates, the linkage block 423 arranged thereon cooperates with the rectangular groove, so that the annular plate 411 also rotates. At this time, the linkage rods 413 inside the four arc-shaped slide grooves 4111 respectively drive their respective rhombus top blocks 412 to slide along the rhombus grooves 211 and move to the inside of the mounting shell 22. As the linkage rods 413 slide into the strip grooves 221, the rhombus top blocks 412 push the folding line push plates 223 inside the respective mounting shells 22 to move, thereby completing the locking and fixation of the bottom plate 3 and the supporting plate 21.

[0055] It should be noted that the pawl 424 arranged inside the circular groove 31 and cooperating with the ratchet 421 is intended to prevent the ratchet 421 from reversing due to vibration or other factors after rotation. The linkage cooperation between the fold line push plate 223 and the diamond-shaped top block 412 connects the bottom plate 3 and the L-shaped base 1 into a whole, further improving the connection strength of the bottom plate 3 installation.
