DETAILED DESCRIPTION

[0026] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0027] See also Figures 1 to 4 The utility model provides a technical solution: a square steel top supporting keel assembly, including a U-shaped top supporting 1, a main keel 2 is arranged inside the U-shaped top supporting 1, an insertion rod 3 is arranged on the bottom surface of the U-shaped top supporting 1, and a number of evenly distributed ribbed steel plates 4 are welded between the bottom surface of the U-shaped top supporting 1 and the outer wall of one end of the insertion rod 3, a thread 301 is provided on the outer wall of the insertion rod 3, and an adjusting nut mechanism 5 is threadedly connected through the thread 301.

[0028] See also Figure 1 and Figure 2 The U-shaped top support 1, the main keel 2 and the insertion rod 3 are welded together as a whole.

[0029] The U-shaped top support 1, the main keel 2 and the insert rod 3 are welded into an integral structure to improve stability and load-bearing capacity. When there is only one vertical rod support point under the bottom beam, the overall structural strength can be relatively increased.

[0030] See also Figure 3 and Figure 4The adjusting nut mechanism 5 includes a nut body 501 , which is threadedly connected to the insertion rod 3 , and four limiting plates 502 are integrally provided in an annular shape on the outer wall of the nut body 501 .

[0031] When the bottom upright pole of the scaffolding middle beam is erected to a certain height, the whole can be inserted into the end of the top upright pole through the insertion rod 3. By rotating the nut body 501 to adjust its position on the insertion rod 3, the U-shaped top support 1 can be adjusted to a suitable elevation. The limiting plate 502 extends outward and is placed on the edge of the insertion hole at the top of the upright pole to limit the whole.

[0032] Furthermore, a sliding groove 503 is provided on one side surface of each limit plate 502, a slider 504 is slidably connected in each sliding groove 503, and a curved clamping plate 506 is fixedly connected to the bottom surface of each slider 504 through a connecting piece 505, and two non-adjacent sliders 504 are connected by an adjustment mechanism.

[0033] The spacing between the two corresponding sliders 504 can be adjusted through the corresponding adjustment mechanism, thereby driving the corresponding two arc-shaped clamps 506 to clamp the vertical pole, reducing the shaking caused when the diameter of the socket at the top of the vertical pole does not match the diameter of the insertion rod 3. At the same time, the nut body 501 as a whole can be further limited to maintain the stability of the whole during the supporting and bearing process.

[0034] Furthermore, an anti-slip protective pad is provided on one side surface of each arc-shaped clamping plate 506 .

[0035] By providing an anti-slip protection pad on one side surface of the arc-shaped clamping plate 506, the friction between the arc-shaped clamping plate 506 and the vertical pole can be increased, further improving the stability of the clamping limit.

[0036] Furthermore, each adjustment mechanism includes two connecting plates 507 and a bidirectional threaded rod 508. Each connecting plate 507 is fixedly mounted on the upper surface of two non-adjacent sliders 504. A threaded hole is provided on one side surface of each connecting plate 507. The two connecting plates 507 are respectively threadedly connected to the two ends of the corresponding bidirectional threaded rod 508 through the threaded holes.

[0037] By rotating the corresponding bidirectional threaded rod 508, the corresponding two connecting plates 507 can be driven to move in opposite directions synchronously, thereby driving the corresponding two sliders 504 to slide synchronously in the corresponding slide grooves 503, so that the two arc-shaped clamping plates 506 can be clamped on both sides of the outer side of the vertical pole, and the clamping stability is maintained by the self-locking property of the threaded connection.

[0038] Furthermore, the middle sections of the bidirectional threaded rods 508 in the two sets of adjustment mechanisms are rotatably mounted on one end of the first mounting bracket 509 and the second mounting bracket 510 respectively. The two bidirectional threaded rods 508 are vertically and staggered in an upper and lower arrangement. The other ends of the first mounting bracket 509 and the second mounting bracket 510 are fixedly connected to the upper surface of the nut body 501.

[0039] The two bidirectional threaded rods 508 are distributed up and down and are vertically staggered, so that they will not interfere with each other during the process of sequential adjustment, thereby improving the efficiency of the splicing operation and reducing limitations during use.

[0040] Working principle: When the spacing between the vertical poles under the beam and slab is 1.5m and one vertical pole is used to return to the top of the beam bottom, when the vertical pole at the bottom of the beam is erected to a certain height, the whole is inserted into the top of the vertical pole through the insertion rod 3, and the nut body 501 adjusts its position on the insertion rod 3 to adjust the U-shaped top support 1 to the appropriate elevation, and the limiting plate 502 is abutted against the top of the vertical pole to complete the limiting. At the same time, the two bidirectional threaded rods 508 are rotated so that the two sets of arc clamps 506 can be clamped circumferentially on the outside of the vertical pole, further improving the stability and firmness of the insertion point, avoiding the independent shaking of the whole relative to the vertical pole, and further limiting the nut body 501. Finally, the secondary keel wood / steel is placed, the wooden formwork is laid, the steel bars are tied and the concrete is poured. The U-shaped top support 1, the main keel 2 and the insertion rod 3 are welded to form an integral structure, which can relatively improve the stability and bearing capacity of the support when there is only one vertical pole support point at the bottom of the beam, thereby relatively improving construction efficiency and reducing labor costs.

[0041] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Those skilled in the art will readily appreciate that the present invention is susceptible to various modifications and variations. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
