[0031] In order to make the purpose, technical solutions and beneficial effects of the present application clearer, the preferred embodiments of the present application will be described in detail below with reference to the accompanying drawings to facilitate understanding by technical personnel.

[0032] Example 1:

[0033] See also Figure 1 and Figure 2 A formwork support suitable for a small-volume trapezoidal cast-in-place concrete structure includes a trapezoidal formwork 1. The formwork support suitable for a small-volume trapezoidal cast-in-place concrete structure includes:

[0034] A transverse shaping rib 2 is horizontally arranged on the top of the trapezoidal formwork 1;

[0035] A first side shaping rib 3 and a second side shaping rib 4 are symmetrically arranged on both sides of the trapezoidal template 1;

[0036] A first reinforcing rib 5 and a second reinforcing rib 6 are symmetrically arranged at both ends of the transverse shaping rib 2;

[0037] Among them, the transverse forming rib 2, the first side forming rib 3, the second side forming rib 4, the first reinforcing rib 5 and the second reinforcing rib 6 are all made of steel. The two ends of the first reinforcing rib 5 are respectively fixedly connected to one end of the transverse forming rib 2 and the side wall of the first side forming rib 3 to form a first triangular support structure. The two ends of the second reinforcing rib 6 are respectively fixedly connected to the other end of the transverse forming rib 2 and the side wall of the second side forming rib 4 to form a second triangular support structure.

[0038] Specifically, the top of the first side shaping rib 3 is fixedly connected to the lower end surface of one side of the transverse shaping rib 2, the upper end of the first reinforcing rib 5 is fixedly connected to the end of the transverse shaping rib 2 close to the first side shaping rib 3, and the lower end of the first reinforcing rib 5 is fixedly connected to the side wall of the first side shaping rib 3. In this way, the three constitute a first triangular support structure.

[0039] The top of the second side shaping rib 4 is fixedly connected to the lower end surface of the other side of the transverse shaping rib 2, the upper end of the second reinforcing rib 6 is fixedly connected to one end of the transverse shaping rib 2 close to the second side shaping rib 4, and the lower end of the second reinforcing rib 6 is fixedly connected to the side wall of the second side shaping rib 4. In this way, the three constitute a second triangular support structure.

[0040] In traditional technology, wooden strips are usually used to support and tie bars to shape the ditch formwork. The connection method mostly adopts nail connection or bolt connection, and the connection strength is limited. In this embodiment, the transverse shaping ribs 2, the first side shaping ribs 3, the second side shaping ribs 4, the first reinforcing ribs 5 and the second reinforcing ribs 6 are all made of steel. Compared with wooden strip supports, steel supports have high tensile, compressive, bending and shear strengths and can withstand large loads and deformations. The connection method between the components adopts a fixed connection. The fixed connection firmly connects multiple components together to form a stable overall structure. This stability helps to resist external loads and deformations and ensure that the structure can maintain its integrity under various conditions. The fixed connection has a high load-bearing capacity and can withstand large loads and stresses. It can also ensure the relative position accuracy between the connected components to avoid displacement or deformation during use. In addition, the use of the first triangular support structure and the second triangular support structure further enhances the load-bearing capacity and stability of the bracket.

[0041] In summary, this application improves the bearing capacity and deformation resistance of the bracket by using steel for the transverse shaping ribs 2, the first side shaping ribs 3, the second side shaping ribs 4, the first reinforcing ribs 5 and the second reinforcing ribs 6, and further improves the bearing capacity by using fixed connections between the components to ensure that the structure can maintain its integrity under various conditions and avoid displacement or deformation during use. The bearing capacity and stability of the bracket are further improved by adopting a triangular support structure, thereby avoiding the problem of template displacement or deformation caused by the bracket being easily deformed after bearing the load, thereby improving the concrete molding quality.

[0042] Example 2:

[0043] See also Figure 1 and Figure 2 Based on the first embodiment, optionally, the first side shaping rib 3 and the second side shaping rib 4 are respectively parallel to the two sides of the trapezoidal template 1 .

[0044] Specifically, by making the first side shaping rib 3 and the second side shaping rib 4 parallel to the two side edges of the trapezoidal template 1 respectively, the force uniformity of the two side edges of the trapezoidal template 1 is improved, thereby enhancing the shaping stability.

[0045] Optionally, the first side shaping ribs 3 and the second side shaping ribs 4 are respectively in contact with two side edges of the trapezoidal template 1 .

[0046] Specifically, the first side shaping ribs 3 and the second side shaping ribs 4 are respectively in contact with the two side edges of the trapezoidal formwork 1 , so as to achieve shaping and support of both sides of the trapezoidal formwork 1 .

[0047] Optionally, the lower end surface of the transverse shaping rib 2 abuts against the top of the trapezoidal template 1 .

[0048] Specifically, the lower end surface of the transverse shaping rib 2 abuts against the top of the trapezoidal formwork 1 to achieve shaping and support of the top of the trapezoidal formwork 1 .

[0049] Optionally, the first reinforcing rib 5 and the second reinforcing rib 6 are respectively welded and fixed to both ends of the transverse shaping rib 2 .

[0050] Specifically, the connection strength is improved by welding to withstand greater loads and stresses, ensure the relative position accuracy between the connection parts, and avoid displacement or deformation of the first reinforcing rib 5, the second reinforcing rib 6 and the transverse shaping rib 2 during use.

[0051] Optionally, both ends of the first reinforcing rib 5 are respectively welded and fixed to one end of the transverse shaping rib 2 and the side wall of the first side shaping rib 3 .

[0052] Specifically, the connection strength is improved by welding to withstand greater loads and stresses, ensure the relative position accuracy between the connection parts, and avoid displacement or deformation of the first reinforcing rib 5 and the transverse shaping rib 2 and the first side shaping rib 3 during use.

[0053] Optionally, both ends of the second reinforcing rib 6 are respectively welded and fixed to the other end of the transverse shaping rib 2 and the side wall of the second side shaping rib 4 .

[0054] Specifically, the connection strength is improved by welding to withstand greater loads and stresses, ensure the relative position accuracy between the connection parts, and avoid displacement or deformation of the second reinforcing rib 6 and the transverse shaping rib 2 and the second side shaping rib 4 during use.

[0055] Optionally, the transverse shaping ribs 2 , the first side shaping ribs 3 , the second side shaping ribs 4 , the first reinforcing ribs 5 and the second reinforcing ribs 6 are all made of square steel or round steel.

[0056] Specifically, square steel is used to improve the convenience of welding while ensuring structural strength; round steel is used to improve structural strength, thereby improving the bearing capacity and deformation resistance of the bracket.
