Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0035] Example 1:

[0036] like Figures 1-3 As shown, the rapid formwork structure for the lower beam provided in this example includes a lower beam body 1, a lower beam template 2 attached to the outer surface of the lower beam body 1, and a ground 8. Multiple first wooden joists 3 are fixedly installed at one end of the lower beam template 2 away from the lower beam body 1. A limiting component 4 is attached to the outer surface of the first wooden joists 3. A second wooden joist 5 is provided at the other end of the limiting component 4 away from the lower beam body 1. A support plate 6 is fixedly installed on the other side of the second wooden joist 5 away from the limiting component 4.

[0037] Further integration Figures 4 to 6 The diagram shows the specific configuration of the limiting component 4 in the preferred implementation of this example.

[0038] Based on the illustration, the limiting assembly 4 in the quick formwork structure of the lower hanging beam specifically comprises a limiting steel frame 401, a plurality of first limiting grooves 402 and second limiting grooves 403 are arranged on the outer surface of the limiting steel frame 401 at equal intervals, and a sliding sleeve 404 is slidably connected to the outer surface of the limiting steel frame 401.

[0039] As a further arrangement, the sliding sleeve 404 in the limiting assembly 4 is fixedly installed with a limiting plate 405 having an isosceles triangular cross-section at the other end away from the limiting steel frame 401, and the limiting plate 405 is in contact with the first wood block 3.

[0040] Here, the sliding sleeve 404 is installed on the limiting steel frame 401, and then the sliding sleeve 404 is slid along the limiting steel frame 401 according to the position of the first wood block 3, so that the limiting plate 405 is tightly attached to the first wood block 3, thereby limiting the first wood block 3. The position of the limiting plate 405 can be conveniently adjusted, and the isosceles triangular structure of the limiting plate 405 can ensure that the first wood block 3 is fixed and its displacement is limited when it is subjected to stress in different directions, thereby ensuring the stability of the lower hanging beam formwork 2 and preventing the formwork from loosening or deforming during concrete pouring, and ensuring the pouring quality of the lower hanging beam body 1.

[0041] As a further arrangement, the limiting plate 405 in the limiting assembly 4 is provided with a first insertion slot 406 and a second insertion slot 408 on the other side away from the lower hanging beam body 1, a first insertion block 407 is inserted and installed in the first limiting groove 402, and a second insertion block 409 is inserted and installed in the second limiting groove 403 and extends to the first insertion block 407.

[0042] By adjusting the limiting plate 405 to the appropriate position through the sliding sleeve 404, the first insertion block 407 is inserted into the first insertion slot 406 and located in the first limiting groove 402, and then the second insertion block 409 is inserted into the second insertion slot 408 and connected with the first insertion block 407, thereby fixing the limiting plate 405. The fixing of the limiting plate 405 on the limiting steel frame 401 is more firm, the multi-layer nested connection mode can effectively prevent the limiting plate 405 from shaking when subjected to external force, and further enhances the fixing effect of the entire limiting assembly 4 on the first wood block 3 and the lower hanging beam formwork 2, thereby ensuring the stability of the formwork structure.

[0043] As a further arrangement, the limiting steel frame 401 in the limiting assembly 4 is provided with a first clamping block 410 at both ends away from the center line, the first clamping block 410 is fixedly installed with a connecting sleeve 411 at the other end away from the limiting steel frame 401, and the connecting sleeve 411 is provided with a groove 412 adapted to the second wood block 5 at the other end away from the lower hanging beam body 1.

[0044] The connection of the limiting assembly 4 and the second wooden block 5 is realized by first inserting the first clamping block 410 into the limiting steel frame 401 at both ends, and then placing the second wooden block 5 in the groove 412 of the connecting sleeve 411, so that the limiting assembly 4 and the second wooden block 5 are better connected, on the one hand, the effective transmission of force between the limiting assembly 4 and the subsequent support structure is ensured, and on the other hand, through this stable connection mode, the force borne by the lower hanging beam formwork 2 is transmitted to the second wooden block 5 and the subsequent support assembly 7 through the first wooden block 3 and the limiting assembly 4, the stability of the entire formwork structure is maintained, and the installation and disassembly process is also facilitated.

[0045] Example two:

[0046] For the lower hanging beam rapid formwork structure scheme given in example one, this example further optimizes the scheme.

[0047] In Figure 1 Based on Figure 2 , further referring to Figure 7 and Figure 8 , this example gives the composition scheme of the support assembly 7 in the lower hanging beam rapid formwork structure.

[0048] Based on the drawings, the support assembly 7 given in this example specifically includes a support steel frame 701, and a connecting seat 702 is fixedly installed at both ends of the support steel frame 701 away from the center line, and a rotating shaft 703 is rotatably installed on the inner surface of the connecting seat 702.

[0049] On this basis, this example further rotatably installs a support rod 704 on the outer surface of the rotating shaft 703, and a positioning bolt 705 threaded connected with the support plate 6 is fixedly installed at the other end of the support rod 704 away from the support steel frame 701. The connecting seat 702, the rotating shaft 703, the support rod 704 and the positioning bolt 705 are provided with the same two groups, each group of connecting seat 702, rotating shaft 703, support rod 704 and positioning bolt 705 is provided with the same two, and the two groups of connecting seat 702, rotating shaft 703, support rod 704 and positioning bolt 705 are symmetrically distributed about the center line of the support steel frame 701.

[0050] Such arrangement can rotate the support rod 704, so that the other end of the support rod 704 abuts against the support plate 6, which can ensure the stability of the support, and the arrangement of two groups and two in each group can make the support force more evenly distributed on the support plate 6, effectively prevent the support plate 6 from tilting or deforming due to uneven force, thereby ensuring the stability of the entire formwork structure and the safety of the lower hanging beam body 1 in the construction process.

[0051] Based on this, this example further includes a fixing seat 706 fixedly installed on the outer surface of the supporting steel frame 701. The inner surface of the fixing seat 706 is provided with a slot 707 and a fixing groove 710. A connecting rod 708 is inserted and installed on the inner surface of the fixing seat 706. Second locking blocks 709 are fixedly installed on both ends of the connecting rod 708 near the fixing seat 706. The fixing groove 710 is adapted to the second locking block 709. The connecting rod 708 connects the two supporting steel frames 701.

[0052] By engaging the slots 707 and 710 within the fixed base 706 with the second locking block 709 on the connecting rod 708, the two supporting steel frames 701 can be connected, increasing the integrity and stability of the supporting assembly 7. This allows multiple supporting steel frames 701 to form a stable supporting network, better bearing the loads transmitted from the lower hanging beam template 2 and the lower hanging beam body 1.

[0053] Based on this, this example further provides a fixing groove 710 on the outer surface of the fixing seat 706, the fixing groove 710 passing through the fixing seat 706 and the connecting rod 708.

[0054] The design of the fixing groove 710 allows for further fixing of the connecting rod 708 and the fixing seat 706 with bolts, which can further improve the stability between the two and can be selected and used according to the actual situation.

[0055] Regarding the rapid formwork structure scheme for suspended beams given in the above example, the operation process is illustrated below with reference to the attached diagram.

[0056] based on Figures 1 to 8 As shown, when using this quick-support formwork structure for the hanging beam, the sliding sleeve 404 is installed on the limiting steel frame 401. Then, according to the position of the first wooden joist 3, the sliding sleeve 404 is slid along the limiting steel frame 401, so that the limiting plate 405 is tightly fitted with the first wooden joist 3, which plays a limiting role for the first wooden joist 3. The position of the limiting plate can be easily adjusted. The limiting plate 405 has an isosceles triangular structure. When it contacts the first wooden joist 3, the stability of the triangle can ensure that the first wooden joist 3 can be better fixed and its displacement is limited when subjected to force in different directions. This ensures the stability of the lower hanging beam formwork 2, avoids the formwork from loosening or deforming during the concrete pouring process, and ensures the pouring quality of the lower hanging beam body 1.

[0057] After adjusting the limiting plate 405 to the appropriate position via the sliding sleeve 404, insert the first insert 407 into the first slot 406 and position one end of it within the first limiting groove 402. Then, insert the second insert 409 into the second slot 408, allowing it to pass through the second limiting groove 403 and connect with the first insert 407, thus completing the fixation of the limiting plate 405. This makes the fixing of the limiting plate 405 on the limiting steel frame 401 more secure. The multi-layer nested connection method can effectively prevent the limiting plate 405 from shaking when subjected to external forces, and further enhances the fixing effect of the entire limiting assembly 4 on the first wooden joist 3 and the lower hanging beam template 2, ensuring the stability of the template structure.

[0058] First, insert the first locking block 410 into both ends of the limiting steel frame 401, and then place the second wooden joist 5 into the groove 412 of the connecting sleeve 411 to connect the limiting component 4 and the second wooden joist 5. This allows for a better connection between the limiting component 4 and the second wooden joist 5, ensuring effective force transmission between the limiting component 4 and the subsequent support structure. On the other hand, this stable connection method transmits the force on the lower beam formwork 2 through the first wooden joist 3 and the limiting component 4 to the second wooden joist 5 and the subsequent support component 7, maintaining the stability of the entire formwork structure. It also facilitates the installation and disassembly process. The rotatable support rod 704 allows its other end to fit against the support plate 6, ensuring the stability of the support. Furthermore, the two sets of two rods each allow the support force to be distributed more evenly on the support plate 6, effectively preventing the support plate 6 from tilting or deforming due to uneven force, thereby ensuring the stability of the entire formwork structure and the safety of the lower beam body 1 during construction.

[0059] By engaging the slots 707 and 710 within the fixing seat 706 with the second locking block 709 on the connecting rod 708, the two supporting steel frames 701 can be connected, increasing the integrity and stability of the supporting assembly 7. This allows multiple supporting steel frames 701 to form a stable supporting network, better bearing the loads transmitted from the lower beam template 2 and the lower beam body 1. The design of the fixing slot 710 also allows for further fixing of the connecting rod 708 and the fixing seat 706 with bolts, further improving the stability between them. This can be selected and used according to the actual situation.
