Utility Model Content

[0003] In order to facilitate the rapid disassembly and installation of the supporting structure of the bridge, the utility model provides a novel spherical supporting structure.

At the same time, when the bolts and nuts between the base and the pressure plate are not tightened, the spherical angle between the base and the movable component can be adjusted, which is also convenient for adapting to the inclination angle of channel bridges of different specifications. After the angle adjustment is completed, the bolts and nuts passing through the base and the pressure plate can be completely locked.

[0007] Preferably, the base includes a concave spherical surface and a lower bracket, the interior of the lower bracket is fixedly connected to a reinforcing column, the lower surface of the concave spherical surface is fixedly connected to the interior of the lower bracket and the top of the reinforcing column, the top and bottom of the lower bracket are each provided with four through holes, wherein L-shaped steel bars are inserted into the interior of the four through holes, the top of each L-shaped steel bar is threadedly connected to the interior of two nuts, and the interior of the concave spherical surface is fixedly connected to a nylon plate.

[0008] Preferably, the movable component includes a T-shaped column and a convex spherical surface, the lower surface of the convex spherical surface is adapted to the top of the nylon plate, and the bottom of the convex spherical surface overlaps the inside of the nylon plate.

[0009] By adopting the above technical solution, the concave spherical surface and the convex spherical surface can be rotated in any direction to adapt to the construction angles of channel bridges of different specifications. The cross bar of the L-shaped steel bar is stuck inside the precast concrete structure, so that the assembled base and one end of the movable component are fixed on the top of the precast concrete structure, so that one end of the channel bridge is connected to the precast concrete structure.

[0012] Preferably, a waterproof cover is fixedly connected to the outer surface of the T-shaped column, the maximum radius of the waterproof cover is equal to the maximum radius of the base, and the pressure plate is located inside the waterproof cover.

A bolt is passed through two corresponding through holes one and one through hole one and one through hole two, and then locked by nuts, so that the pressure plate and the base can be detachably connected, and the movable component and the eye plate can be detachably connected.

[0016] In summary, the present invention has the following beneficial technical effects:

[0017] 1. This device is provided with a base, a movable component and a pressure plate. The base and the prefabricated concrete structure can be detachably connected by L-shaped steel bars and nuts. The base and the pressure plate, as well as the movable component and the eye plate can be detachably connected by threads and bolts, which is convenient for disassembly and installation, and helps to reduce the time of disassembly and installation. At the same time, when the bolts and nuts between the base and the pressure plate are not tightened, the spherical angle between the base and the movable component can be adjusted, which is also convenient for adapting to the inclination angle of channel bridges of different specifications. When the angle adjustment is completed, the bolts and nuts passing through the base and the pressure plate can be completely locked;

[0018] 2. This device is provided with two spherical surfaces, a concave spherical surface and a convex spherical surface. The concave spherical surface and the convex spherical surface can be rotated in any direction to adapt to the construction angles of different specifications of channel bridges. The cross bar of the L-shaped steel bar is stuck inside the precast concrete structure, so that the assembled base and one end of the movable component are fixed to the top of the precast concrete structure, thereby connecting one end of the channel bridge to the precast concrete structure of the port. The support structure can also be used for other precast concrete structures to support other functional building structures. The concave spherical surface and the convex spherical surface are protected by nylon plates to prevent the concave spherical surface and the convex spherical surface from colliding when the concave spherical surface is directly connected, resulting in potholes on the surface of the concave spherical surface and the convex spherical surface.

[0019] 3. The device is provided with a waterproof cover to protect the base and movable components, and to block all large waves from entering the supporting structure.

The bottom of the movable component 2 is overlapped on the top of the base 1. The bottom of the eye plate 3 is detachably connected to the movable component 2 through a part of the bolts 4. The top of the base 1 is detachably connected to a pressure plate 5 through another part of the bolts 4. The pressure plate 5 is sleeved on the bottom of the movable component 2. The base 1 is installed on the precast concrete structure 10 through L-shaped steel bars 6 and nuts. The top of the movable component 2 is fixed on the eye plate 3 of the channel bridge. The crane lifts the channel bridge toward the precast concrete structure 10 until the convex spherical surface 22 of the movable component 2 is located in the concave spherical surface 11, and then the pressure plate 5 is connected to the base 1 through the bolts 4 to limit the up and down movement of the movable component 2. After the inclination angle of the movable component 2 is adjusted to meet the installation requirements of the channel bridge, tighten the bolts 4 and nuts, and clamp the convex spherical surface 22 through the pressure plate 5 and the concave spherical surface 11, thereby completing the construction of the channel bridge;

[0033] When the base 1 and the movable component 2 are not on the access bridge, they can be fixed on other prefabricated concrete structures through the connection of through hole 1 and through hole 2. The base 1 and the movable component 2 can be fixed on two different concrete structures respectively, or the base 1 and the movable component 2 can be combined and installed on the same concrete structure, so as to facilitate transportation or provide support for other building structures.

[0034] Reference Figure 1 、 Figure 5The base 1 includes a concave spherical surface 11 and a lower bracket 12. The interior of the lower bracket 12 is fixedly connected with a reinforcing column, which provides support for the concave spherical surface 11. At the same time, the lower bracket 12 and the T-shaped column 21 are hollow, which can also save materials, reduce weight and facilitate transportation. The lower surface of the concave spherical surface 11 is fixedly connected to the interior of the lower bracket 12 and the top of the reinforcing column. The bottom and top of the lower bracket 12 are each provided with four through holes 1, wherein the interiors of the four corresponding through holes 1 are each inserted with L-shaped steel bars 6, which are reserved rods. When the base 1 is installed, the vertical rods of the L-shaped steel bars 6 are inserted into the through holes 1, and the cross rods of the L-shaped steel bars 6 are fixed in the concrete prefabricated structure 10. The top of each L-shaped steel bar 6 is threadedly connected to the interior of the two nuts. The interior of the concave spherical surface 11 is fixedly connected with a nylon plate 7.

The movable component 2 itself is in the shape of an inverted umbrella. The lower surface of the convex spherical surface 22 and the interior of the concave spherical surface 11 are both spherical. The lower surface of the convex spherical surface 22 is adapted to the top of the nylon plate 7, and the bottom of the convex spherical surface 22 is overlapped with the interior of the nylon plate 7.

The outer surface of the pressure plate 5, the top of the T-shaped column 21 and the bottom of the eye plate 3 are all provided with through holes 2, and several bolts 4 are inserted into the corresponding through holes 2. When the convex spherical surface 22 is located inside the concave spherical surface 11, as long as the nut is not tightened, the movable component 2 can continue to be rotated to adjust the angle between the movable component 2 and the base 1.

The maximum radius of the waterproof cover 9 is equal to the maximum radius of the base 1. The pressure plate 5 is located inside the waterproof cover 9. The top of the waterproof cover 9 is connected to the T-shaped column 21. The top of the waterproof cover 9 and the top of the T-shaped column 21 form an inverted bowl shape, which protects the T-shaped column 21, the convex spherical surface 22, the concave spherical surface 11 and the top of the lower bracket 12, preventing the waves from impacting the convex spherical surface 22 and the concave spherical surface 11, and protecting the spherical surface of the supporting structure.

[0040] 1. The base 1 is installed on the precast concrete structure 10 using L-shaped steel bars 6 and nuts. The top of the movable assembly 2 is fixed to the eye plate 3 of the access bridge. The access bridge is hoisted toward the precast concrete structure 10 by a crane until the convex spherical surface 22 of the movable assembly 2 is located within the concave spherical surface 11. The pressure plate 5 is then connected to the base 1 using bolts 4 to restrict the up and down movement of the movable assembly 2. After the inclination angle of the movable assembly 2 is adjusted to meet the installation requirements of the access bridge, the bolts 4 and nuts are tightened to clamp the convex spherical surface 22 through the pressure plate 5 and the concave spherical surface 11, thereby completing the access bridge construction.
