[0020] In the description of the present utility model, it should also be noted that unless otherwise clearly defined and limited, if the terms "set", "installed", "connected", "connected" appear, they 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 mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

[0021] The following will be combined with Figures 1 to 3 to make a detailed description of the present utility model.

[0022] A concrete pouring device for the inclined rod of the box girder of a single cable-plane cable-stayed bridge includes an outer mold 1. The middle part of the outer mold 1 is connected with an inner mold 2. The middle part of the inner mold 2 is connected with an inclined rod mold 201. Fitting grooves 202 are arranged on both sides of the inclined rod mold 201. A closed groove 203 is arranged on one side of the fitting groove 202. A connecting bolt 204 is connected in the middle of the fitting groove 202. A abutting component is connected in the middle of the closed groove 203. The connecting bolt 204 passes through the abutting component, and the abutting component is driven to displace by the connecting bolt 204.

[0023] First, the concrete is poured and formed between the outer mold 1 and the inner mold 2 to make the box girder. At the same time, the inclined rod is also poured through the cavity of the inclined rod mold 201 in the middle of the inner mold 2 to increase the support stability of the box girder after pouring.

[0024] Furthermore, the inclined rod mold 201 is assembled by combining several steel plates. The fitting grooves 202 are arranged on the surfaces of the inclined rod molds 201 on the opposite sides. The inclined rod mold 201 cooperates with the fitting grooves 202. Screw holes 205 are arranged at the two ends of the inclined rod mold 201 close to the fitting grooves 202. The screw holes 205 cooperate with the connecting bolts 204.

[0025] At the same time, when assembling the inclined rod mold 201, two of the inclined rod molds 201 are inserted into the fitting grooves 202 of the other two for connection to form a rectangular mold. After the insertion is completed, the connecting bolts 204 pass through the outer wall of the fitting grooves 202 and are connected with the screw holes 205 on the two inclined rod molds 201. Therefore, at the edge part during the assembly of the inclined rod mold 201, in addition to bolt connection, there is also a fitting setting, making the connection edge part of the inclined rod mold 201 more stable and not deformed due to the influence of concrete stress on the unconnected part of the connecting bolt 204.

[0026] Furthermore, the abutting component includes an abutting block 2031, a connection hole 2032, a through ring 2033 and a limit ring 2034. The abutting block 2031 is arranged in the middle of the closed groove 203. The connection hole 2032 is arranged in the middle of the abutting block 2031. The through ring 2033 is connected in the connection hole 2032. The limit ring 2034 is arranged on the side wall of the through ring 2033. The abutting block 2031 is several squares connected in the closed groove 203, and the size of the abutting block 2031 matches the closed groove 203. The through ring 2033 is a ring rotatably connected in the middle of the connection hole 2032 through the side wall limit ring 2034. The through ring 2033 is penetrated and connected by the connecting bolt 204, and the inner wall of the through ring 2033 is thread-matched with the side wall of the connecting bolt 204.

[0027] Then, when the connecting bolt 204 passes through the closed groove 203 and is connected to the screw hole 205, it will pass through the abutting block 2031 in the closed groove 203, and cooperate with the connecting bolt 204 through the through-ring 2033 of the connecting hole 2032 in the middle of the abutting block 2031. At the same time, the through-ring 2033 is limit-connected to the connecting hole 2032 through the limit ring 2034. When the connecting bolt 204 penetrates into the through-ring 2033, the friction will increase due to the thread matching of the two. The side wall of the limit ring 2034 is provided with balls for reducing friction, so that when the connecting bolt 204 rotates and enters, it will drive the through-ring 2033 to rotate together, so that the through-ring 2033 will move together with the rotation and entry of the connecting bolt 204. Then, driven by the limitation of the limit ring 2034, the abutting block 2031 will be displaced together until it abuts against the part of the inclined rod template 201 fitted in the fitting groove 202. Then, due to the abutment, the abutting block 2031 cannot continue to be displaced. As a result, when the connecting bolt 204 continues to rotate and enter, it will only enter along the thread on the inner wall of the through-ring 2033 and will not drive the through-ring 2033 to continue to move. During this process, the generated rotational force will force the abutting block 2031 to press against the part of the inclined rod template 201 fitted in the fitting groove 202, so that the part of the inclined rod template 201 fitted in the fitting groove 202 will be strengthened, and the part of the connecting bolt 204 without connection can also be strengthened and will not easily deform.

[0028] The following is the specific implementation process of the present utility model. First, concrete is poured and formed between the outer mold 1 and the inner mold 2 to produce a box girder. At the same time, a diagonal bar is also poured through the cavity of the diagonal bar template 201 in the middle of the inner mold 2 to increase the support stability of the box girder after pouring. At the same time, when assembling the diagonal bar template 201, two of the diagonal bar templates 201 are inserted into the fitting grooves 202 of the other two for connection, thus forming a rectangular mold. After the insertion is completed, the connecting bolts 204 pass through the outer wall of the fitting groove 202 and are connected to the screw holes 205 on the two diagonal bar templates 201, so that in the edge part of the diagonal bar template 201 during assembly, in addition to bolt connection, there is also a fitting setting, making the connecting edge part of the diagonal bar template 201 more stable and not deformed due to the influence of concrete stress on the unconnected part of the connecting bolt 204. Then, when the connecting bolt 204 passes through the closed groove 203 and is connected to the screw hole 205, it will pass through the abutting block 2031 in the closed groove 203, and cooperate with the connecting bolt 204 through the through-ring 2033 of the central connection hole 2032 of the abutting block 2031. At the same time, the through-ring 2033 is limited and connected to the connection hole 2032 through the limiting ring 2034, so that when the connecting bolt 204 penetrates into the through-ring 2033, the friction will increase due to the thread matching of the two. The side wall of the limiting ring 2034 is provided with anti-friction balls, so that when the connecting bolt 204 rotates and enters, it will drive the through-ring 2033 to rotate together, so that the through-ring 2033 will move together with the rotation and entry of the connecting bolt 204. Then, driven by the limitation of the limiting ring 2034, the abutting block 2031 will move together until it abuts against the part of the diagonal bar template 201 fitted in the fitting groove 202. Then, due to the abutment, the abutting block 2031 cannot continue to move, so that when the connecting bolt 204 continues to rotate and enter, it will only enter along the thread on the inner wall of the through-ring 2033 and will not drive the through-ring 2033 to continue to move. And the rotational force generated in this process will force the abutting block 2031 to press against the part of the diagonal bar template 201 fitted in the fitting groove 202, so that the part of the diagonal bar template 201 fitted in the fitting groove 202 will be strengthened, and the unconnected part of the connecting bolt 204 can also be strengthened and will not be easily deformed.

[0029] The above is only the preferred embodiment of the present utility model and is not used to limit the present utility model. For those skilled in the art, the present utility model can have various changes and modifications. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present utility model shall be included in the protection scope of the present utility model.
