Description

Technical Field

[0001] The utility model relates to a steel cage structure, in particular to a steel cage structure for prestressed concrete pipe piles. Background Art

[0002] A steel cage is a prefabricated steel structure, mainly used to reinforce concrete structures. It is mainly composed of steel bars, which are welded to form a grid structure to constrain concrete and improve the integrity and tensile strength of concrete components. The main function of the steel cage is to resist tensile forces. Because concrete has high compressive strength but low tensile strength, the steel cage can effectively improve the bending and shear resistance of concrete. In the construction of bridges, culverts or high-rise buildings, steel cages are used when foundation piling is required.

[0003] The patent with the patent authorization announcement number CN204959733U discloses a cast-in-place pile steel cage structure, including a steel cage body, the bottom of which is fixedly connected to an anti-floating structure for preventing the steel cage body from floating up by the concrete turned out of the pouring conduit and impacting downward, and the bottom of the steel cage body is provided with reinforcing ribs, which pass through the anti-floating structure and are fixedly connected to the main bars of the steel cage body.

[0004] Although the above patent can prevent the steel cage body from floating up and reduce the construction difficulty by setting an anti-floating structure, there are still some shortcomings in actual use. For example, when using the steel cage structure, the height of the steel structure is fixed. When the height of the steel structure is insufficient, two or more steel structures need to be fixed on site manually. Welding technology is generally used for fixing, and there are many positions that need to be welded between the two steel structures, so welding will consume a lot of time, which is not convenient for the quick use of the steel cage structure.

[0005] Therefore, a steel cage structure for prestressed concrete pipe piles is particularly needed to solve the problems existing in the prior art. Utility Model Content

[0006] In order to overcome the disadvantage of the prior art that when the height of the steel bar structure is not enough, two or more steel bar structures need to be fixed together manually on site, and welding technology is generally used for fixing. However, there are many positions that need to be welded between the two steel bar structures, so welding will consume a lot of time, which makes it inconvenient to quickly use the steel bar cage structure. The utility model provides a steel bar cage structure for prestressed concrete pipe piles.

[0007] The utility model is realized through the following technical approaches: a steel cage structure for prestressed concrete pipe piles, comprising a mounting plate, an end plate a, a steel bar a and an end cap, the mounting plate is provided with mounting holes evenly spaced along the circumferential direction, the mounting plate is provided with steel bars a through the mounting holes, the other ends of the steel bars a are fixedly connected with the end plate a, and the bottom ends of the steel bars a are fixedly connected with the end cap, and also comprises a clamping block, a connecting spring and an inclined surface, the upper part of the mounting plate is slidably connected with symmetrically distributed clamping blocks, a circular groove with the same diameter as the steel bar a is formed between two adjacent clamping blocks, and at least one connecting spring for assisting resetting and applying force is connected between the clamping block and the mounting plate, an inclined surface is provided on the upper part of the clamping block, and an oblique angle corresponding to the inclined surface is provided on the end cap.

[0008] In addition, it is particularly preferred that a guide plate is also included, and the guide plates distributed in a circular path are fixedly connected inside the mounting plate, and there is a certain distance between two adjacent guide plates, and this distance just accommodates a steel bar a passing through, and every two adjacent blocks are located between every two guide plates.

[0009] In addition, it is particularly preferred that a threaded steel bar is further included, and the threaded steel bar is placed on the mounting plate.

[0010] In addition, it is particularly preferred that the upper part of the installation plate is provided with concave openings distributed in a cross path, and the threaded steel bars are placed between the longitudinally aligned concave openings so that the top surface of the threaded steel bars is lower than the top surface of the installation plate and is on a different horizontal plane.

[0011] In addition, it is particularly preferred that a connecting disk is further included, and the bottom of the end plate a is fixedly connected with the connecting disk, and the connecting disk has the same size as the annular cavity inside the mounting disk, so that the connecting disk can be completely embedded in the mounting disk.

[0012] Furthermore, it is particularly preferred that the thickness of the connecting plate is equal to the distance between the top surface of the threaded steel bar and the top surface of the mounting plate.

[0013] The above description of the structure of the utility model shows that the design starting point, concept and advantages of the utility model are:

[0014] 1. By setting a clamping block, a connecting spring and an inclined plane, the second steel cage structure is moved downward to a suitable position so that the end bevel is out of contact with the inclined plane, and the end surface is completely in contact with the two adjacent clamping blocks. The connecting spring assists the two adjacent clamping blocks to move inward to cooperate with the clamping of the end, so as to achieve the purpose of quickly splicing the steel cage structure and solve the problem that the prior art is not convenient for quickly using the steel cage structure.

[0015] 2. By providing a connecting plate, the connecting plate is completely embedded in the annular cavity of the mounting plate, thereby increasing the splicing area between the second steel cage structure and the first steel cage structure, and improving the stability of the splicing between the two.

DETAILED DESCRIPTION

[0022] In order to make the purpose, technical solution and advantages of the utility model clearer, the utility model is further described in detail below in combination with specific implementation methods and with reference to the accompanying drawings. It should be understood that these descriptions are only exemplary and are not intended to limit the scope of the utility model. In addition, in the following description, the description of well-known structures and technologies is omitted to avoid unnecessary confusion of the concept of the utility model.

[0023] Embodiment: A steel cage structure for prestressed concrete pipe piles, see Figure 1-Figure 5As shown, it includes a mounting plate 4, an end plate a1, a steel bar a2, an end head 3, a guide plate 5, a threaded steel bar 10 and a connecting plate 12. The mounting plate 4 is provided with mounting holes 6 evenly spaced along the circumferential direction. The mounting plate 4 is provided with steel bars a2 through the mounting holes 6. The other end of the steel bar a2 is fixedly connected with the end plate a1, and the bottom end of the steel bar a2 is connected with the end head 3 by welding. The mounting plate 4 is connected with guide plates 5 distributed in a circular path by welding. There is a certain distance between two adjacent guide plates 5, and this distance just accommodates a steel bar a2 to pass through, and every two adjacent blocks 7 are located between every two guide plates 5. Threaded steel bars 10 are placed on the mounting plate 4. The upper part of the mounting plate 4 is provided with concave openings 11 distributed in a cross path. The threaded steel bars 10 are placed between the concave openings 11 aligned in the longitudinal direction, so that the top surface of the threaded steel bars 10 is lower than the top surface of the mounting plate 4. On different horizontal planes, the bottom of the end plate a1 is connected to a connecting plate 12 by welding. The connecting plate 12 is the same size as the annular cavity inside the mounting plate 4, so that the connecting plate 12 can be completely embedded in the mounting plate 4, and the connecting plate 12 is made of vacuum sealing rubber material and has a relatively slow compressive stress, so that the connecting plate 12 is not easy to fall out after being embedded in the mounting plate 4. The thickness of the connecting plate 12 is equal to the distance between the top surface of the threaded steel bar 10 and the top surface of the mounting plate 4. It also includes a clamping block 7, a connecting spring 8 and an inclined surface 9. The upper part of the mounting plate 4 is slidably connected with symmetrically distributed clamping blocks 7, and a circular groove with the same diameter as the steel bar a2 is formed between two adjacent clamping blocks 7, and at least one connecting spring 8 for assisting resetting and applying force is connected between the clamping block 7 and the mounting plate 4. A bevel 9 is provided on the upper part of the clamping block 7, and an oblique angle corresponding to the bevel 9 is provided on the end head 3, and the height of the bevel angle is consistent with the height of the bevel 9.

[0024] First, the staff places the second steel cage structure just above the first steel cage structure, aligning the steel bar a2 between the two adjacent guide plates 5, and then moves the second steel cage structure downward so that the bevel of the end head 3 is in contact with the inclined surface 9 in advance to squeeze the two adjacent blocks 7 to move outward, and the connecting spring 8 is compressed accordingly. When the second steel cage structure is moved downward to a suitable position, the bevel of the end head 3 is out of contact with the inclined surface 9. When the surface of the end head 3 is completely in contact with the two adjacent blocks 7, the connecting spring 8 returns to its original state, and then the two adjacent blocks 7 move inward to cooperate in clamping the end head 3, thereby achieving the purpose of quickly splicing the steel cage structure and solving the problem that the existing steel cage structure is not convenient for quick use. At the same time, the connecting plate 12 is completely embedded in the annular cavity of the mounting plate 4, thereby increasing the splicing area between the second steel cage structure and the first steel cage structure and improving the stability of the splicing between the two. The staff repeats the above steps to splice an appropriate amount of steel structures.
