Description

Technical Field

[0001] This application relates to the technical field of cast-in-place bridge construction, and particularly to a cast-in-place system for a steel pipe column bracket-supported Bailey main girder. Background Art

[0002] With the acceleration of the urbanization process and the continuous development of infrastructure construction, bridge engineering, as an important part of urban transportation, has an increasing construction scale and construction difficulty. During the bridge construction process, the cast-in-place box girder, as a commonly used structural form, its construction quality and efficiency are directly related to the safety and economy of the entire bridge project. Therefore, it is of great significance to study and apply an efficient and stable cast-in-place box girder support system.

[0003] Traditional cast-in-place box girder support systems mostly adopt structural forms such as steel pipe scaffolds and bowl-coupled scaffolds. Although these systems meet the construction requirements to a certain extent, they often have problems such as insufficient stability, long construction period, and high costs when facing complex working conditions such as high piers and large spans. For this reason, the cast-in-place system for a steel pipe column bracket-supported Bailey main girder has emerged as the times require and has become an effective way to solve these problems.

[0004] The Bailey bracket is an essential part of the steel pipe column bracket-supported Bailey main girder type bracket. The Bailey bracket is mainly composed of adjacent Bailey plates spliced together. At present, a male head and a female head are respectively arranged at both ends of the Bailey plate. During splicing, first, the male head and the female head are spliced, and then they are locked by the cooperation of bolts and nuts. Since the male head is inserted into the female head from one end of the Bailey plate, the bolt will bear the torsion force when the male head and the female head are misaligned due to force, which may easily cause the bolt to loosen or break, thereby reducing the safety of the device. Summary of the Utility Model

[0005] The purpose of this application is to solve the problem that since the male head is inserted into the female head from one end of the Bailey plate, the bolt will bear the torsion force when the male head and the female head are misaligned due to force, which may easily cause the bolt to loosen or break, thereby reducing the safety of the device. This application provides a cast-in-place system for a steel pipe column bracket-supported Bailey main girder.

[0006] This application specifically adopts the following technical solutions to achieve the above purpose:

[0013] Furthermore, a receiving groove is formed at one end of the mounting block, and the driving handle is mounted inside the receiving groove.

[0014] By adopting the above technical solution, through the combined use of the storage groove and the driving handle, it is convenient to complete the storage and protection of the driving handle, reducing the external force touching the driving handle, resulting in the situation that the lifting slider contacts and loosens with the female head and male head due to accidental touching of the driving handle, and improving the safety of the device.

[0015] Further, one end of the lifting slider is fixedly connected with a supporting wide plate.

[0017] Further, one end of the locking bolt is movably sleeved with a locking gasket, and the locking gasket is installed between the locking nut and the Bailey plate.

[0018] By adopting the above technical solution, through the combined use of the locking gasket and the locking nut, the friction area between the locking nut and the Bailey plate is effectively increased, further improving the connection stability between the female head and the male head, and reducing the situation that the locking bolt and the locking nut become loose.

Detailed implementation manners

[0029] The following will further elaborate on this application Figures 1 - 3 in conjunction with the accompanying drawings.

[0030] The embodiment of this application discloses a cast-in-place system for a steel pipe column bracket supporting a Bailey main beam.

[0031] Referring to Figures 1 - 3 , a cast-in-place system for a steel pipe column bracket supporting a Bailey main beam includes an I-beam 1. A pair of Bailey trusses 2 are symmetrically installed on the top of the I-beam 1. One end of each Bailey truss 2 is symmetrically and fixedly connected with a female head 3, and the other end of each Bailey truss 2 is symmetrically and fixedly connected with a male head 4 adapted to the female head 3. A connecting beam 5 is inserted between the two oppositely arranged Bailey trusses 2. One end of the connecting beam 5 is symmetrically and fixedly connected with a mounting block 6. A storage slide rail 7 is opened inside the mounting block 6. A pair of jacking sliders 8 are symmetrically slidably connected inside the storage slide rail 7. A jacking rod 9 is rotatably connected inside the storage slide rail 7. One end of the jacking rod 9 is symmetrically provided with threads with opposite helix directions. One end of the jacking slider 8 is provided with a jacking screw groove 10 threadedly connected with the jacking rod 9. One end of the female head 3 is provided with a locking assembly for connecting the male head 4 and the female head 3. One end of the mounting block 6 is provided with a driving assembly for driving the jacking rod 9 to rotate;

[0032] Among them, the driving assembly includes a bevel gear one 14 fixedly connected to one end of the jacking rod 9. A bevel gear two 15 meshing with the bevel gear one 14 is rotatably connected inside the storage slide rail 7. One end of the bevel gear two 15 passes through the mounting block 6 and is fixedly connected with a driving handle 16;

[0033] Moreover, a storage groove 17 is opened at one end of the mounting block 6, and the driving handle 16 is installed inside the storage groove 17;

[0034] Furthermore, one end of the lifting slide block 8 is fixedly connected to a supporting wide plate 18 .

[0035] When in use, first pull a Bailey piece 2 to drive the male head 4 to insert into the female head 3 at one end of the other Bailey piece 2, then tighten the locking assembly to fix the two adjacent Bailey pieces 2, then pull the connecting beam 5 to drive a mounting block 6 to be embedded between the two adjacent Bailey pieces 2, then insert the hand into the storage groove 17 to rotate the driving handle 16, so that the driving handle 16 drives the bevel gear 2 15 to engage with the bevel gear 1 14, and the bevel gear 1 14 drives the lifting rod 9 to rotate, and at the same time, the lifting rod 9 and the lifting screw groove 10 form a threaded connection. The two lifting sliders 8 are connected and pushed to move away from each other along the length direction of the storage slide rail 7, and at the same time, the lifting sliders 8 push the supporting wide plate 18 to form a resistance against one end of the female head 3 and the male head 4. As a result, when one end of the female head 3 and the male head 4 are under pressure, the lifting sliders 8 push the supporting wide plate 18 to form a resistance support against one end of the female head 3 and the male head 4, thereby improving the force support strength of the female head 3 and the male head 4, reducing the deviation of the force on the female head 3 and the male head 4, improving the stability of the device, and reducing the possibility of loosening or damage to the locking assembly.

[0036] Reference Figure 1 and Figure 2 The locking assembly includes locking through holes 11 symmetrically provided at one end of the female head 3 and the male head 4, a locking bolt 12 is inserted into the locking through hole 11, and a locking nut 13 is threadedly connected to one end of the locking bolt 12;

[0037] Among them, a locking washer 19 is provided on a movable sleeve at one end of the locking bolt 12, and the locking washer 19 is installed between the locking nut 13 and the Bailey plate 2.

[0038] When in use, the locking bolt 12 is manually pulled through the locking through hole 11 to pass through the male head 4 and the female head 3, and then the locking nut 13 is tightened to push the locking washer 19 to move along the length direction of the locking bolt 12, and the locking nut 13 pushes the locking washer 19 to form a fixed contact with one end of the Bailey plate 2, thereby realizing the fixed connection between the female head 3 and the male head 4. At the same time, the double locking through holes 11 and the locking bolt 12 are arranged to cooperate with each other, which effectively improves the connection strength between the female head 3 and the male head 4.

[0039] Reference Figure 1 and Figure 2 The surfaces of the I-beam 1, the Bailey sheet 2 and the female head 3 are all coated with an organic silicone waterproof coating.

[0040] In use, an organosilicon waterproof coating is applied to the surfaces of the I-beam 1, the Bailey truss 2, and the male head 3, forming a waterproof protective layer on the surfaces of the I-beam 1, the Bailey truss 2, and the male head 3, effectively improving the corrosion resistance of the device surface and extending the service life of the device.

[0041] The implementation principle of a cast-in-place system for a steel pipe column bracket supporting a Bailey main beam in this embodiment is as follows: First, tow a Bailey truss 2 to drive the male head 4 to insert into the female head 3 at one end of another Bailey truss 2. Then, tow the locking bolt 12 through the locking perforation 11 to pass through the male head 4 and the female head 3, and then tighten the locking nut 13 to push the locking gasket 19 to move along the length direction of the locking bolt 12, and make the locking nut 13 push the locking gasket 19 to form a fixed contact with one end of the Bailey truss 2, so as to realize the fixed connection between the female head 3 and the male head 4.

[0042] Then, tow the connecting beam 5 to drive an installation block 6 to be embedded between two adjacent Bailey trusses 2, and then insert the hand into the internal part of the storage groove 17 to rotate the driving handle 16, so that the driving handle 16 drives the second bevel gear 15 to mesh with the first bevel gear 14, and makes the first bevel gear 14 drive the jacking rod 9 to rotate. At the same time, make the jacking rod 9 form a threaded connection with the jacking screw groove 10, and push two jacking sliders 8 to move away from each other along the length direction of the storage slide rail 7. At the same time, make the jacking sliders 8 push the supporting wide plate 18 to form a contact with one end of the female head 3 and the male head 4. Furthermore, when one end of the female head 3 and the male head 4 bears pressure, the jacking sliders 8 push the supporting wide plate 18 to form a contact support with one end of the female head 3 and the male head 4.
