[0030] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a direct connection, or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0031] See attached Figure 1 to Figure 2 , a schematic embodiment of the tire frame for the hanging basket cantilever cast-in-place beam proposed by the utility model is given, and the tire frame for the hanging basket cantilever cast-in-place beam is composed of a base frame assembly 1 and a vertical frame assembly 2.

[0032] The base frame assembly 1 includes a plurality of first rods 11 arranged in parallel, and a limiter 3 is arranged on the first rods 11. The vertical frame assembly 2 is divided into two groups, the left and right groups, and the two groups of vertical frame assemblies 2 are arranged on the base frame assembly 1. The distance between the two groups of vertical frame assemblies 2 is determined according to the size of the cast-in-place beam segment of the hanging basket cantilever.

[0033] Each set of stand components 2 is composed of a second rod 21 and a third rod 22. The second rods 21 are the same number as the first rods 11 and are hinged one-to-one, and multiple second rods 21 are arranged in parallel. The third rods 22 are the same number as the second rods 21 and are corresponding one-to-one. Each third rod 22 has a first end and a second end. The first end of each third rod 22 is hinged to the corresponding second rod 21, and the second end of each third rod 22 abuts against the stopper 3 on the first rod 11 to lock the angle between the first rod 11 and the second rod 21. See the attached Figure 1 The first rod 11, the third rod 22 and the limiter 3 form a triangular structure, which can resist external pressure and load and maintain the stability and firmness of the structure.

[0034] There are multiple limit members 3, and the multiple limit members 3 are spaced apart by a set distance so that the angle between the first rod 11 and the second rod 21 is locked at different angles. Figure 1 and Figure 2 When constructing different hanging basket cantilever cast-in-place beams, it is only necessary to adjust the second end of the third rod 22 to abut against different limit members 3 to change the angles α and β.

[0035] In this embodiment, the angle α between the second rod 21 of the left group of frame assemblies 2 and the first rod 11 and the angle β between the second rod 21 of the right group of frame assemblies 2 and the first rod 11 can be adjusted independently, thereby increasing the flexibility and applicability of the cradle for the cantilever cast-in-place beam of the hanging basket.

[0036] In order to increase the structural stability of the tire frame for the hanging basket cantilever cast-in-place beam, in this embodiment, the base frame assembly 1 also includes a first reinforcing rod 12, which is arranged on a plurality of first rods 11 arranged in parallel, and is located between a group of upright frame assemblies 2 on the left and a group of upright frame assemblies 2 on the right, and a plurality of first reinforcing rods 12 are provided. A first steel nail is inserted at the intersection of the first reinforcing rod 12 and the first rod 11. The provision of the first steel nail can firmly connect the first reinforcing rod 12 and the first rod 11 together, thereby improving the bearing capacity of the tire frame for the hanging basket cantilever cast-in-place beam and ensuring the quality and safety of the construction.

[0037] Taking practical applications into consideration, in this embodiment, six first reinforcing rods 12 are provided, and the spacing between adjacent first reinforcing rods 12 is 1.2 m. Under the premise of ensuring that the cradle for the cantilever cast-in-place beam of the hanging basket is sufficiently stable, the procurement and use of raw materials can be reduced, thereby reducing production costs.

[0038] In order to increase the structural stability of the tire frame for the hanging basket cantilever cast-in-place beam, in this embodiment, each set of the frame assembly 2 also includes a second reinforcement rod 23, which is arranged on the second rod 21 and is located at the hinged connection between the third rod 22 and the second rod 21. A second steel nail is inserted at the intersection of the second reinforcement rod 23 and the second rod 21. The provision of the second steel nail can firmly connect the second reinforcement rod 23 and the second rod 21 together, thereby improving the bearing capacity of the tire frame for the hanging basket cantilever cast-in-place beam and ensuring the quality and safety of the construction.

[0039] The number of the first rods 11 is determined according to the segment size of the cantilever cast-in-place beam of the hanging basket, see the attached Figure 1 In this embodiment, eight first rods 11 are provided, and the interval between adjacent first rods 11 is 0.6 m.

[0040] In this embodiment, the base frame assembly 1 and the stand frame assembly 2 are made of wood. Compared with other metals or composite materials, wood is low in cost and economical and practical. In addition, wood is easy to process and manufacture, the manufacturing process is simple, the manufacturing cycle is short, and the construction efficiency is improved.

[0041] In the above-mentioned schematic embodiment, the tire frame for the hanging basket cantilever cast-in-place beam is composed of a base frame assembly and a vertical frame assembly. The base frame assembly includes a first rod and a plurality of limit members, and the vertical frame assembly includes a second rod and a third rod. It has a simple structure, and the angle between the first rod and the second rod is adjustable. It has strong applicability and can be reused, saving construction costs.

[0042] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and each embodiment focuses on the differences from other embodiments. The same or similar parts between the various embodiments can be referenced to each other.

[0043] The above embodiments are only used to illustrate the technical solution of the utility model rather than to limit it. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in the field should understand that the specific implementation methods of the utility model can still be modified or some technical features can be replaced by equivalents without departing from the spirit of the technical solution of the utility model, which should be included in the scope of the technical solution for which protection is requested in the utility model.
