[0022] In order to better understand the purpose, structure and function of the present invention, the following is a further detailed description of a support assembly for bridge construction of the present invention in conjunction with the accompanying drawings.

[0023] like Figures 1 to 5 As shown, a support assembly for bridge construction of the present invention comprises a mounting beam 1, a horizontal beam 2 is detachably provided at the top of the mounting beam 1, a connecting block 3 is provided on the bottom surface of the horizontal beam 2 away from the mounting beam 1, and a support beam 4 is rotatably provided on the connecting block 3, and the free end of the support beam 4 can be detachably connected with the mounting beam 1. Specifically, a first extension block 5 is provided at one end of the horizontal beam 2 close to the mounting beam 1, and a first connecting shaft 6 is provided on the first extension block 5. A groove 7 and a clamping groove 8 are respectively provided on the mounting beam 1 to accommodate the insertion of the first extension block 5 and the first connecting shaft 6, and a limit assembly 12 for fixing the first connecting shaft 6 is provided at the positions corresponding to the clamping groove 8 on both sides of the mounting beam 1. At the same time, a second extension block 10 is also provided at the bottom end of the support beam 4, and a second connecting shaft 11 is provided on the second extension block 10. A force groove 9 is provided on the mounting beam 1 to accommodate the insertion of the second extension block 10, and a limit assembly 12 for fixing the second connecting shaft 11 is provided on both sides of the mounting beam 1. It should be noted that the support beam 4 is set on the horizontal beam 2 through the connecting block 3. When the corbel bracket is transported, the support beam 4 can be folded relative to the horizontal beam 2, thereby reducing the space occupied by the horizontal beam 2 and the support beam 4 during transportation and improving the practicality of the corbel bracket.

[0024] Among them, when installing the horizontal beam 2 on the mounting beam 1, the first extension block 5 on the horizontal beam 2 can be placed into the groove 7 first, and then the horizontal beam 2 can be pushed to move, and the first connecting shaft 6 can be inserted into the slot 8, and then the first connecting shaft 6 can be limited by the limiting component 12 to prevent the first connecting shaft 6 from coming out of the slot 8. When installing the support beam 4, the second connecting shaft 11 and the second extension block 10 can be inserted into the force groove 9, and after the second connecting shaft 11 is fully inserted into the force groove 9, the corresponding limiting component 12 can be used to limit it, so that the assembly of the corbel bracket can be completed, which is convenient, fast, time-saving and labor-saving. It should be noted that the length of the first connecting shaft 6 and the second connecting shaft 11 is greater than the width of the mounting beam 1, so that it is convenient for the limiting component 12 set on the mounting beam 1 to limit the first connecting shaft 6 or the second connecting shaft 11 adapted thereto.

[0025] The limiting assembly 12 for limiting the first connecting shaft 6 and the second connecting shaft 11 includes a rotating shaft 121 rotatably arranged on the mounting beam 1, a clamp 122 is arranged on the rotating shaft 121, the clamp 122 is semicircular, ratchet teeth 123 are distributed on the outer periphery of the clamp 122, and the clamp 122 can rotate around the rotating shaft 121. A mounting frame 124 is also arranged on the side wall of the mounting beam 1, the mounting frame 124 is ∩-shaped, and a ratchet block 125 that can slide up and down is arranged in the mounting frame 124, and a spring 126 is arranged between the ratchet block 125 and the mounting frame 124. At the same time, a pull rod 127 is arranged on the ratchet block 125 and located in the spring 126, and the pull rod 127 passes through the mounting frame 124 and is slidably arranged therewith. In this way, when the first connecting shaft 6 moves into the slot 8, the clamp 122 will be pushed to rotate around the rotating shaft 121, and after the first connecting shaft 6 is inserted into the slot 8, the clamp 122 is manually rotated to limit the first connecting shaft 6, and the ratchet 123 on the clamp 122 is engaged with the ratchet block 125, so as to achieve the purpose of limiting the first connecting shaft 6. When it is necessary to release the clamp 122 from limiting the first connecting shaft 6, the ratchet block 125 connected to it can be lifted by the pull rod 127, so that the ratchet block 125 is disengaged from the ratchet 123 on the clamp 122, and then the clamp 122 is rotated in the opposite direction, so that the clamp 122 can release the limit on the first connecting shaft 6. Similarly, the disassembly and assembly work of the second connecting shaft 11 in the force groove 9 is also the same, which will not be elaborated in detail here.

[0026] Preferably, a slide groove is provided at the free end of the horizontal beam 2, and an extension beam 13 is slidably provided in the slide groove, that is, the extension beam 13 can slide out of the slide groove of the horizontal beam 2, thereby increasing the load area of ​​the horizontal beam 2 and improving the practicality of the bracket. A positioning bolt 21 is also rotatably provided on one side of the horizontal beam 2, and the positioning bolt 21 penetrates the slide groove and contacts the extension beam 13. The positioning bolt 21 can be used to fix the extension beam 13, thereby improving the safety of the extension beam 13 on the horizontal beam 2.

[0027] As another preferred embodiment, a placement groove 14 is also provided on the bottom surface of the extension beam 13, and a support rod is rotatably provided in the placement groove 14. The connection position between the support rod and the placement groove 14 has friction force, and the position is fixed without applying external force after the support rod rotates, and then the free end of the support rod is supported on the connection block 3, which can increase the bearing capacity of the extension beam 13. In order to increase the stability of the support rod on the connection block 3, an adjustment cylinder 18 is rotatably provided on the connection block 3, and the support rod can be inserted into the adjustment cylinder 18.

[0028] As a further improvement, there are two ears 16 on the connecting block 3, and a loading plate 17 is rotatably provided between the two ears 16. An adjusting cylinder 18 is rotatably provided on the loading plate 17, and a nut 19 is provided on the outer periphery of the adjusting cylinder 18. Among them, the support rod is a screw 15, and an internal thread is provided in the adjusting cylinder 18. After the extension beam 13 is extended, the screw 15 and the adjusting cylinder 18 are rotated so that the free end of the screw 15 is aligned with the free end of the adjusting cylinder 18, and then the adjusting cylinder 18 is rotated to screw the screw 15 into the adjusting cylinder 18 to complete the connection between the two. At the same time, according to the required extension length of the extension beam 13, the adjusting cylinder 18 can be rotated to adjust the length of the screw 15 entering the adjusting cylinder 18. Figure 5 As shown, in order to increase the stability of the screw rod 15 in the placement groove 14 , a paddle 20 for limiting the screw rod 15 is provided in the placement groove 14 .

[0029] Instructions for use: First, place the first extension block 5 in the groove 7, then push the horizontal beam 2 so that the first connecting shaft 6 is inserted into the slot 8, and the first connecting shaft 6 is limited by the limiting assembly 12. Rotate the support beam 4 on the connection block 3, and align the second connecting shaft 11 on the second extension block 10 with the force groove 9, then insert the second connecting shaft 11 and the second extension block 10 into the force groove 9, and use the limiting assembly 12 to limit the second connecting shaft 11, thereby completing the installation of the corbel bracket. When disassembling, just pull the pull rod 127 on the limiting assembly 12, so that the pull rod 127 drives the ratchet block 125 to rise, release the engagement between the ratchet block 125 and the ratchet 123 on the clamp 122, and then rotate the clamp 122 in the opposite direction to release the limiting of the clamp 122 on the first connecting shaft 6 or the second connecting shaft 11 that it matches.
