[0025] In order to make the purpose, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below in conjunction with the embodiments and the accompanying drawings. Here, the exemplary embodiments of the present invention and their descriptions are used to explain the present invention, but are not intended to limit the present invention.

[0026] Reference Figure 1 、 Figure 2 and Figure 3 A post-cast strip support structure includes adjustable uprights 1, joists 2, and formwork 3. Two rows of joists 2 are arranged in parallel, and multiple formwork 3 are installed between the two rows of joists 2. Top supports 4 are provided between adjacent joists 2 in the same row of joists 2. The adjacent joists 2 are connected by the top supports 4. Each top support 4 corresponds to an adjustable upright 1, and the top support 4 is fixed to the top of the adjustable upright 1.

[0027] The adjustable upright pole 1 includes a lower pole 11 and an upper pole 12. The bottom of the upper pole 12 is inserted into the lower pole 11. An external thread is provided on the outer wall of the top of the lower pole 11. The top of the lower pole 11 is threadedly connected to an adjusting sleeve 13. Two hand-held rings 14 are fixed on the outer wall of the adjusting sleeve 13. The two hand-held rings 14 are symmetrically arranged about the axis of the adjusting sleeve 13.

[0028] Two elongated holes 15 are provided on the outer wall at the top of the lower rod 11. The two elongated holes 15 are symmetrically arranged about the axis of the lower rod 11, and the length direction of the elongated holes 15 is arranged along the axis direction of the lower rod 11. A plurality of connecting holes 16 are provided on the upper rod 12, and the plurality of connecting holes 16 are evenly arranged along the length direction of the upper rod 12. A latch 17 is inserted into one of the connecting holes 16, and the top surface of the adjusting sleeve 13 is pressed against the latch 17. When it is necessary to adjust the overall length of the upper rod 12 and the lower rod 11, the position of the connecting hole 16 corresponding to the adjusting sleeve 13 can be adjusted, or the adjusting sleeve 13 can be rotated to adjust the overall height of the upper rod 12 and the lower rod 11.

[0029] The outer walls of the top support 4 are both vertical, bend inward, and then straighten again. Two first support plates 41 are fixed to the bottom of the top support 4. The first support plates 41 are placed horizontally, with a gap between the two first support plates 41. The top of the upper rod 12 passes through the gap and is fixed to the top support 4. A support sleeve 42 is threadedly connected to the upper rod 12 and is located below the first support plates 41 to support the two first support plates 41.

[0030] Reference Figure 4 、 Figure 5 and Figure 6 , square steels 5 are provided on both sides of the top support 4, and the square steels 5 are located on the first support plate 41, and the first support plate 41 supports the square steels 5. Second support plates 21 are fixed on both sides of the joist 2, and the second support plates 21 support the formwork 3. A first connecting plate 22 is fixed to the bottom of the second support plate 21, and two second connecting plates 23 are fixed below the first connecting plate 22. A third support plate 24 is fixed to the bottom of the second connecting plate 23, and the third support plate 24 is arranged horizontally. The third support plate 24 is flush with the first support plate 41. The first connecting plates 22 of the two adjacent joists 2 sandwich the top support 4 in the middle, and the two ends of the square steel 5 are respectively located on the third support plates 24 of the two adjacent joists 2. Pins 25 are provided on the square steel 5, and the second connecting plates 23 and the square steel 5 are fixed by the pins 25.

[0031] The principle of the post-cast strip support structure of the present invention is as follows: when handling garbage in the post-cast strip, the pin 25 is pulled out, separating the joist 2 from the top support 4. The joist 2 and formwork 3 can be removed, while the adjustable upright 1 remains. This method allows the post-cast strip to be removable, eliminating the top handling process. It also solves the problem of post-cast strips being extremely difficult to clean in previous construction processes, and solves quality problems such as slag inclusion in the post-cast strip concrete, thereby improving the construction quality of the post-cast strip.

[0032] The present invention also discloses a construction method of a post-cast strip support structure:

[0033] S1. Position and lay out the lines, and simultaneously erect the post-casting strip support structure and the surrounding formwork support structure;

[0034] Install the base of the adjustable pole 1 and the adjustable pole 1, and install the top support 4 on the adjustable pole 1;

[0035] S2. Adjust the height of the top support 4 to correspond to the height of the post-casting strip formwork 3;

[0036] S3. Align the joist 2 with the top support 4 and connect the joist 2 and the top support 4 with the square steel 5 and the pins 25;

[0037] S4, placing the template 3 on the second support plate 21 on the joist 2;

[0038] S5. Before pouring the post-cast strip, clean the garbage in the post-cast strip. When cleaning the garbage, pull out the pin 25 to separate the joist 2 from the top support 4. The formwork 3 and the joist 2 can be removed, thereby facilitating the cleaning of the garbage in the post-cast strip. After cleaning, the joist 2 and the formwork 3 are reinstalled.

[0039] This method features a rational and reliable structural design, enabling convenient installation of the aluminum alloy formwork post-casting strip support device. Furthermore, post-casting strip debris can be cleaned without removing the adjustable uprights 1. Compared to traditional methods, this method offers better waterproofing, improved overall structural stability, and a higher safety factor for the support system. Furthermore, the method is height-adjustable, enabling application in post-casting strip construction at varying storey heights, effectively enhancing applicability. The installation process is quick and easy, effectively improving construction efficiency. This method offers the advantages of low cost, rapid disassembly, and high practicality.

[0040] The above description is only a preferred embodiment of the present invention and is not intended to limit the scope of protection of the present invention. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention are included in the scope of protection of the present invention.
