Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, a cast-in-place box girder support includes a top plate formwork 1, and a support body fixed between the top plate formwork 1 and the ground, the support body includes columns 2 and crossbeams 3, multiple columns 2 are arranged perpendicular to the top plate formwork 1, and the columns 2 are respectively fixed to the top plate formwork 1 and the ground by bolts, the columns 2 are adjustable with connecting components 4, and multiple crossbeams 3 are detachably connected between adjacent columns 2 from top to bottom through the connecting components 4, and the crossbeams 3 are orthogonally arranged to the columns 2, and the connecting components 4 can facilitate the disassembly of the columns 2 and the crossbeams 3.

[0024] Specifically, the top plate formwork 1 serves as the top platform of the construction, and is used to support the weight and pressure during concrete pouring. The main body of the bracket is composed of columns 2 and beams 3. The columns 2 are vertically arranged between the top plate formwork 1 and the ground to ensure the stability and bearing capacity of the entire bracket. The columns 2 are fixed to the top plate formwork 1 and the ground by bolts. The use of bolts can ensure the stability of the columns 2. The columns 2 are covered with connecting components 4. The connecting components 4 allow the height of the columns 2 to be fine-tuned to meet the needs of different construction heights. Adjacent columns 2 are sequentially connected with multiple beams 3 through connecting components 4. The beams 3 are orthogonal to the columns 2, that is, the beams 3 cross the columns 2 vertically. The connecting components 4 allow the beams 3 to be easily disassembled and connected to the columns 2, which provides flexibility for construction and is easy to install and disassemble, while ensuring the stability and safety of the structure.

[0025] The connecting assembly 4 includes a positioning sleeve 5 and four connecting sleeves 6. The positioning sleeve 5 is sleeved on the column 2. A locking bolt is screwed on the positioning sleeve 5. The four connecting sleeves 6 are respectively fixed on the sides of the positioning sleeve 5, and adjacent connecting sleeves 6 are arranged perpendicular to each other. The crossbeam 3 can be inserted into the connecting sleeve 6, and an iron plate is fixed to the side end of the crossbeam 3. A magnet block is fixed in the connecting sleeve 6.

[0026] The connecting sleeve 6 also includes a positioning piece and a limiting piece. The limiting piece is fixedly connected inside the positioning piece. A protrusion 7 is fixed on the side of the crossbeam 3. The protrusion 7 can be embedded in the positioning piece and limited by the limiting piece.

[0027] The positioning member includes a long through hole 8 fixed on the side of the connecting sleeve 6, and a limiting hole 9 is fixed at the side end of the long through hole 8. The protrusion 7 can slide along the long through hole 8 into the limiting hole 9 and slide in the limiting hole 9. A plurality of anti-slip protrusions are fixed on the contact surface between the limiting hole 9 and the protrusion 7. The length of the protrusion 7 is set equal to the length of the limiting hole 9.

[0028] The limiting member includes a limiting block 10 arranged at the side end of the limiting hole 9, and the limiting block 10 can close the limiting hole 9. The limiting block 10 is inserted into the through hole and fixedly connected to one end of the spring 11. The spring 11 is fixed in the through hole, and the through hole is fixed in the long through hole 8.

[0029] Specifically, the positioning sleeve 5 is sleeved on the column 2 and is locked by bolts to ensure that its position is fixed; four connecting sleeves 6 are fixed on the side of the positioning sleeve 5 and are arranged perpendicular to each other so as to be able to connect the crossbeams 3 in different directions; an iron plate is fixed to the side end of the crossbeam 3, and the iron plate can be inserted into the connecting sleeve 6 and interact with the magnet block in the connecting sleeve 6 to achieve connection;

The limiting member is fixed in the positioning member, and a protrusion 7 is fixed on the side of the cross beam 3. The protrusion 7 can slide along the long through hole 8 in the positioning member, and then the cross beam 3 is rotated so that it is finally embedded in the limiting hole 9;

[0031] A plurality of anti-slip protrusions are fixed on the contact surface between the limiting hole 9 and the protrusion 7, which helps to prevent the protrusion 7 from sliding in the limiting hole 9 and ensure the stability of the crossbeam 3. The length of the protrusion 7 is set equal to the length of the limiting hole 9 to ensure that the protrusion 7 can be completely embedded in the limiting hole 9;

[0032] When the protrusion 7 slides into the long through hole 8, the limit block 10 generates a force, the spring 11 is compressed, the limit block 10 enters the through hole, and then the cross beam 3 is rotated, so that the protrusion 7 slides into the limit hole 9 again. At this time, the limit block 10 will be pushed by the spring 11, and the limit block 10 closes the limit hole 9, ensuring that the protrusion 7 is firmly locked in the limit hole 9, thereby fixing the position of the cross beam 3.

[0033] A displacement sensor 12 is also fixedly connected to the bottom of the top plate template 1, and the displacement sensor 12 is arranged at the side end of the column 2. The pull rope of the displacement sensor 12 is fixedly connected to the embedded plumb bob 13 on the ground. The displacement sensor 12 is electrically connected to the controller 15 for transmission, and the controller 15 is electrically connected to the sound and light alarm 14 for control. The displacement sensor 12, the sound and light alarm 14 and the controller 15 are electrically connected to the external power supply device 16 respectively.

[0034] A displacement sensor 12 is fixed on the top plate template 1, and the pull wire of the displacement sensor 12 is connected and fixed to the embedded plumb bob 13. If the bracket body is deformed, the displacement sensor 12 will transmit the shortened data to the controller 15. If the displacement exceeds the input value, the controller 15 will control the sound and light alarm 14 to issue an alarm in time.

[0035] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
