[0015] The embodiments of the present utility model are described in further detail below in conjunction with the accompanying drawings.

[0016] like Figure 1 , 2 As shown in 3, the embedded high-support formwork supporting device includes an embedded component and a supporting component.

[0017] The embedded component is embedded in the concrete body and connected to the structural steel bars in the concrete body. The embedded component is used to fix the supporting component and bear the load of the high formwork system. The embedded component includes a steel plate 1 and threaded steel bars 2. The threaded steel bars 2 are multiple and evenly arranged on the steel plate 1. The threaded steel bars 2 are cast into one piece with the concrete and connected to the structural steel bars in the concrete body. The steel plate 1 is exposed on the surface of the concrete body.

[0018] The support member provides a carrier for the high formwork system and receives the load of the high formwork system, and is specifically a triangular support structure welded on the steel plate 1. The triangular support structure includes a steel plate 2 3 welded on the steel plate 1 and a pair of triangular steel plates 4, and the triangular steel plates 4 are respectively welded on the steel plate 2 3.

[0019] The installation process of the utility model is as follows: first, a plurality of threaded steel bars 2 are evenly arranged on a steel plate 1 and welded firmly; then, a plurality of threaded steel bars 2 are buried in the concrete body before pouring, and connected with the structural steel bars in the concrete body; after the concrete body formwork is removed, the floating slurry on the steel plate 1 is removed, and the triangular support structure of the support member is welded to the exposed steel plate 1 of the embedded member to form a double triangular support form, and a high formwork system is installed layer by layer on the support structure.

[0020] The specific usage scenarios are as follows:

[0021] The actual steel plates are all Q235, and the threaded rods are 25#. Applied to the high-support formwork construction of the top beam of the main tower of the suspension bridge, the embedded high-support formwork support device is composed of several units, each unit includes 1 square steel plate (Q235, 700*700*20mm), 12 threaded steel bars (1000*25mm), 1 square steel plate (Q235, 500*500*20mm) and 2 triangular steel plates (Q235, 50*50*20mm) welded together. For a single main tower, the above 6 units are required to support the high-support formwork system.

[0022] For each unit, the specific arrangement is: 12 threaded steel bars (1000*25mm) are evenly laid out on the square steel plate (Q235, 700*700*20mm), arranged in three rows, with four threads in each row, and then embedded in the concrete body and connected to its structural steel bars; after the concrete body is poured, the triangular supporting structure consisting of a square steel plate (Q235, 500*500*20mm) and two triangular steel plates (Q235, 50*50*20mm) are welded to the square steel plate (Q235, 700*700*20mm) on the exposed concrete body surface.

[0023] The height of the beam from the ground is 29.4 meters. The embedded high formwork support device is set at 26.4 meters on the double wings of the main tower, and then the high formwork system including the main beam (worker 45), cross beam (worker 16), distribution beam (worker 10), steel pipe scaffolding, top support, and cross beam bottom formwork is set up in sequence. This device effectively reduces the erection height, construction risk and resource investment of the steel pipe scaffolding.

[0024] In addition, to ensure construction safety, relevant data calculations and verifications should be carried out before construction; before the structural reinforcement process, a pre-compression test should be carried out on the bottom formwork of the concrete body, and subsequent construction processes can only be carried out after confirmation.

[0025] The above is only a preferred embodiment of the present invention. It should be pointed out that ordinary technicians in this technical field can make several improvements and modifications without departing from the concept of the present invention. These improvements and modifications should also be regarded as within the scope of protection of the present invention.
