Description

Technical Field

[0001] This utility model relates to the field of end plate technology, specifically an end plate with a reinforced structure. Background Technology

[0002] In pipe pile engineering applications, the end plate is a key component for the end connection of pipe piles, and its performance directly affects the quality and stability of the pipe pile connection. Traditional end plates are usually composed of a single plate, which can meet the basic requirements for the connection of the main reinforcement and steel bars of the pipe pile, but it is clearly insufficient when facing complex engineering environments or high load-bearing requirements.

[0003] On the one hand, as the scale of construction projects continues to expand, the requirements for the bearing capacity of pipe piles are increasing. During use, pipe piles need to withstand the huge loads of the superstructure and complex geological forces. Traditional end plates, due to their simple structure and limited strength, are prone to deformation and damage when subjected to long-term stress or large loads, which in turn affects the overall performance and structural safety of the pipe piles.

[0004] On the other hand, in some special engineering scenarios, such as soft soil foundations and seismically active areas, the mechanical environment faced by pipe piles is more complex. Traditional end plates are difficult to effectively cope with these complex mechanical forces, which may lead to problems such as loosening and cracking at the pipe pile connection, seriously affecting the project quality and service life. In addition, traditional end plates are also prone to damage during construction if they are subjected to accidental collisions or improper construction operations, increasing the risk of construction costs and project delays.

[0005] Therefore, developing an end plate structure with higher strength and better stability to adapt to different engineering environments and load-bearing requirements has become an urgent problem to be solved in the field of pipe pile engineering. Utility Model Content

[0006] The purpose of this invention is to provide an end plate with a reinforced structure to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution: an end plate with a reinforced structure, comprising an end plate body, the surface of which is provided with a plurality of main reinforcement anchor holes and rebar holes, reinforcing pads inserted into the upper and lower sides of the end plate body, an extension pad II integrally formed at the outer ring of the reinforcing pad, a connecting block fixed to the surface of the extension pad II, the connecting block being inserted into the surface of the end plate body, and a plurality of reserved holes provided on the surface of the reinforcing pad, the reserved holes corresponding to the main reinforcement anchor holes and rebar holes.

[0008] Preferably, the end plate body has assembly grooves on both the upper and lower sides. The assembly grooves are annular grooves, the reinforcing pad is annular, one end of the reinforcing pad is inserted into the assembly groove, and the thickness of the reinforcing pad is greater than the depth of the assembly groove.

[0009] Preferably, the inner ring surface of the reinforcing pad is integrally formed with an extension pad, the inner ring diameter of the extension pad is equal to the inner ring diameter of the end plate body, and the thickness of the extension pad is equal to the height of the reinforcing pad protruding from the assembly groove.

[0010] Preferably, the thickness of the second extension pad is equal to the thickness of the first extension pad, the outer ring diameter of the second extension pad is equal to the outer ring diameter of the end plate body, the outer ring surface of the end plate body is provided with multiple notches, the connecting block is inserted into the notches, and the height of the connecting block is equal to half the height of the notch.

[0011] Preferably, the surface of the connecting block is fixed with a splicing post, which is a semi-cylinder with external threads. After the extension pads are installed on both sides of the end plate body, the connecting blocks on the surfaces of the two sets of extension pads are inserted into the notches. The splicing posts on the surfaces of the two connecting blocks are spliced ​​to form a threaded stud, and a nut is screwed onto the stud.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] The end plate with a reinforced structure proposed in this utility model forms a new, stronger plate structure by inserting reinforcing pads on the upper and lower sides of the end plate body, along with extension pad one and extension pad two. This multi-layered composite structure can effectively distribute the load borne by the pipe pile, improve the overall compressive and bending resistance of the end plate, and enable the end plate to maintain structural stability and integrity when facing complex engineering environments and high load-bearing requirements, greatly improving the reliability of the pipe pile connection.

[0014] The connecting blocks fixed to the two surfaces of the extension pad are inserted into the grooves on the surface of the end plate body, and are assembled into threaded studs by splicing columns, and then fixed with nuts. This connection method makes the connection between the reinforcing pad and the end plate body more secure, effectively preventing the reinforcing pad from falling off during use, further enhancing the stability of the end plate structure, and ensuring the safety of the pipe pile connection.

[0021] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0022] Please see Figures 1 to 5 This utility model provides a technical solution: an end plate with a reinforced structure, including an end plate body 1. The surface of the end plate body 1 is provided with a plurality of main reinforcement anchor holes 102 and rebar holes 103. Reinforcing pads 2 are inserted into the upper and lower sides of the end plate body 1. An extension pad 4 is integrally formed on the outer ring of the reinforcing pad 2. Assembly grooves 101 are provided on the upper and lower sides of the end plate body 1. The assembly grooves 101 are annular grooves. The reinforcing pad 2 is annular plate. One end of the reinforcing pad 2 is inserted into the assembly groove 101. The thickness of the reinforcing pad 2 is greater than the depth of the assembly groove 101. An extension pad 3 is integrally formed on the inner ring surface of the reinforcing pad 2. The inner ring diameter of the extension pad 3 is equal to the inner ring diameter of the end plate body 1, and the thickness of the extension pad 3 is equal to the height of the reinforcing pad 2 protruding from the assembly groove 101.

[0023] The end plate body 1 can be used alone. That is, after the end plate body 1 is laid on the end of the pipe pile, the main reinforcement of the pipe pile passes through the main reinforcement anchor hole 102, and the reinforcement of the pipe pile passes through the reinforcement hole 103. In order to improve the strength of the end plate body 1, reinforcing pads 2 can be inserted on both the upper and lower sides of the end plate body 1. At this time, the surface of the end plate body 1 is covered by the reinforcing pad 2, the extension pad 1 3 and the extension pad 2 4. The two sets of reinforcing pads 2, extension pad 1 3 and extension pad 2 4 constitute a new plate with greater strength. The main reinforcement and reinforcement of the pipe pile pass through the main reinforcement anchor hole 102 and the reinforcement hole 103 and then extend out from the reserved hole 201.

[0024] To strengthen the connection between the reinforcing pad 2 and the end plate body 1, the following was proposed:

[0025] A connecting block 5 is fixed to the surface of the extension pad 2 4. The connecting block 5 is inserted into the surface of the end plate body 1. The surface of the reinforcing pad 2 has multiple reserved holes 201, which correspond to the anchor holes 102 and the reinforcing bar holes 103. The thickness of the extension pad 2 4 is equal to the thickness of the extension pad 1 3. The outer ring diameter of the extension pad 2 4 is equal to the outer ring diameter of the end plate body 1. The outer ring surface of the end plate body 1 has multiple notches 104. The connecting block 5 is inserted into the notch 104. The height of the connecting block 5 is equal to half the height of the notch 104. A splicing post 6 is fixed to the surface of the connecting block 5. The splicing post 6 is a semi-cylinder with external threads. After the extension pad 2 4 is installed on both sides of the end plate body 1, the connecting blocks 5 on the surfaces of the two sets of extension pad 2 4 are inserted into the notch 104. The splicing posts 6 on the surfaces of the two connecting blocks 5 are spliced ​​to form a threaded stud. A nut 7 is screwed onto the stud.

[0026] After the reinforcing pad 2 is inserted into the surface of the end plate body 1, the corresponding connecting block 5 on the outside of the reinforcing pad 2 is inserted into the notch 104. The nut 7 is screwed onto the stud formed by the two splicing posts 6 inside the notch 104. In this way, the connecting block 5 pulls the extension pad 2 4 and the reinforcing pad 2 firmly against one side of the end plate body 1, preventing the reinforcing pad 2 from falling off.

[0027] How to use end plates with reinforced structures:

[0028] This end plate is suitable for pipe pile end connection scenarios, taking a common 600mm diameter pipe pile as an example. The outer ring diameter of the end plate body 1 is 600mm, the inner ring diameter is set to 400mm according to the internal structure of the pipe pile, and the thickness of the end plate body 1 is set to 20mm. The diameter of the main reinforcement anchor holes 102 is 30mm, a total of 8 are set, evenly distributed on the surface of the end plate body 1; the diameter of the rebar holes 103 is 20mm, a total of 12 are set, also evenly distributed. The reinforcing pad 2 is an annular plate, with an outer ring diameter of 600mm, the same as the outer ring diameter of the end plate body 1, and an inner ring diameter of 400mm, the same as the inner ring diameter of the end plate body 1, and a thickness of 15mm. The assembly groove 101 is an annular groove with a depth of 10mm. The thickness of the extension pad 1 3 and the extension pad 2 4 is 15mm (the same as the thickness of the reinforcing pad 2), and the outer ring diameter of the extension pad 2 4 is equal to the outer ring diameter of the end plate body 1, which is 600mm. The notch 104 is set to a width of 20mm and a height of 15mm (to match the height of the connecting block 5, which is half the height of the notch 104, i.e., 7.5mm). Four notches are evenly distributed along the outer ring surface of the end plate body 1. The splicing post 6 is a semi-cylinder with external threads, with a diameter of 10mm. Two splicing posts 6 are joined together to form a stud with a diameter of 10mm. The inner diameter of the nut 7 is matched with the stud diameter of 10mm.

[0029] Method for using end plate body 1 alone: ​​Transport the pipe pile to the designated location on the construction site and place it stably, ensuring that the end of the pipe pile is flat and clean, free of debris, protrusions, or depressions that may affect the installation of the end plate. Carefully lay end plate body 1 on the end of the pipe pile, aligning the center of end plate body 1 with the center of the pipe pile end, ensuring a tight fit between end plate body 1 and the pipe pile end without gaps. Pass the main reinforcement bars of the pipe pile one by one through the main reinforcement anchor holes 102 on end plate body 1, ensuring that the insertion depth of the main reinforcement bars meets the design requirements (insertion depth not less than 50mm); at the same time, pass the reinforcing bars of the pipe pile one by one through the reinforcing bar holes 103 on end plate body 1, ensuring that the reinforcing bars are inserted smoothly and in accurate positions.

[0030] Using the reinforced structure method: Check that the reinforcing pad 2, extension pad one 3, extension pad two 4, connecting block 5, splicing column 6, and nut 7 are intact and complete. Ensure that the reserved hole 201 on the reinforcing pad 2 corresponds to the position of the main reinforcement anchor hole 102 and the rebar hole 103 on the end plate body 1. Holding the reinforcing pad 2, align one end of the reinforcing pad 2 with the assembly groove 101 on the end plate body 1, and slowly and steadily insert the reinforcing pad 2 into the assembly groove 101. Because the thickness of the reinforcing pad 2 (15mm) is greater than the depth of the assembly groove 101 (10mm), a portion of the reinforcing pad 2 will protrude outside the assembly groove 101 after insertion. During the insertion process, carefully observe the position of the reinforcing pad 2 to ensure that the inner ring diameter of the integrally formed extension pad 3 is aligned with the inner ring diameter of the end plate body 1, and that the thickness (15mm) of the extension pad 3 is equal to the height of the reinforcing pad 2 protruding from the assembly groove 101 (5mm plus the 5mm protruding part of the reinforcing pad 2 that is not fully occupied in the 10mm depth of the assembly groove 101, so that the overall protrusion effect meets the requirements).

[0031] Place the extension pad 2 (4) on the outside of the reinforcing pad 2, aligning the connecting block 5 fixed on the surface of the extension pad 2 (4) with the notch 104 on the outer circumference of the end plate body 1. Slowly push the extension pad 2 (4) to insert the connecting block 5 into the notch 104 until the connecting block 5 is fully inserted. At this point, the splicing post 6 fixed on the surface of the connecting block 5 also enters the notch 104. Similarly, insert the reinforcing pad 2, install the extension pad 2 (4), and the connecting block 5 on the other side of the end plate body 1. Ensure that the reinforcing structures on both sides are installed symmetrically and in accurate positions. After the extension pads 2 (4) are installed on both sides of the end plate body 1, the splicing posts 6 on the connecting blocks 5 of the two extension pads 2 (4) will be close to each other inside the notch 104. Align and assemble the two splicing posts 6 so that their external threads interlock to form a complete stud. Holding nut 7, place it onto the assembled stud. Then, using a suitable tool (such as a wrench), screw nut 7 onto the stud until it is tightened. This ensures that the connecting block 5, the extension pad 4, and the reinforcing pad 2 are firmly against one side of the end plate body 1, preventing the reinforcing pad 2 from falling off. Pass the main reinforcement bars and steel bars of the pipe pile through the reserved holes 201 on the reinforcing pad 2 (the reserved holes 201 correspond to the main reinforcement anchor holes 102 and the steel bar holes 103), ensuring smooth insertion and that the insertion depth meets the design requirements.

[0032] By following the steps above, the installation and use of the end plate with reinforced structure can be completed, effectively improving the strength of the end plate and meeting the requirements for pipe pile end connection.
