Description

Technical Field

[0001] This utility model relates to the field of bridge construction technology, and more specifically, to a pre-embedded climbing cone component. Background Technology

[0002] A climbing cone is a system of embedded parts used in building and bridge construction. Its main function is to provide temporary fixing points to facilitate the installation and removal of various formwork, supports, and other auxiliary structures during construction. A typical climbing cone system includes embedded parts in the pier, load-bearing bolts connected to the embedded parts and providing support, the climbing cone body connected to the load-bearing bolts, and bolts connected to the climbing cone body.

[0003] When using the climbing cone, the embedded parts, load-bearing bolts, and climbing cone are assembled and then fixed to the pier casting mold with bolts. After the pier concrete has solidified, the climbing cone can be used to connect various formwork, supports, and other auxiliary structures during construction. However, during the dismantling of the climbing cone, the load-bearing bolts are in direct contact with the concrete, resulting in significant frictional resistance and affecting the dismantling efficiency. Utility Model Content

[0004] The problem this invention addresses is: how to improve the efficiency of removing the load-bearing bolts in a climbing cone assembly.

[0005] To solve the above problems, this utility model provides a pre-embedded climbing cone assembly, including a pre-embedded part, a load-bearing bolt, a sleeve, and a climbing cone. The sleeve is fitted onto the load-bearing bolt, and the two ends of the load-bearing bolt in the axial direction are respectively connected to the pre-embedded part and the climbing cone.

[0006] Optionally, the embedded part is provided with a groove, and a positioning block is provided in the groove. The positioning block is rotatably connected to the side wall of the groove by a spring. The connecting end of the force-bearing bolt is provided with a positioning groove. The connecting end extends into the groove and squeezes the spring. After the positioning groove is aligned with the positioning block, the spring drives the positioning block to engage with the positioning groove.

[0007] Alternatively, the embedded part is provided with the groove, and the positioning block is provided in the groove. The positioning block is moved on the embedded part by an elastic element along the depth direction perpendicular to the groove. The connecting end of the force-bearing bolt is provided with the positioning groove. The connecting end extends into the groove and squeezes the elastic element. After the positioning groove and the positioning block are aligned, the elastic element drives the positioning block to engage with the positioning groove.

[0008] Optionally, a protruding strip is provided on the connecting end, and a sliding groove is also provided in the groove, with the protruding strip and the sliding groove being slidably connected.

[0009] Optionally, the positioning block is configured with a conical structure at both ends in the depth direction of the groove, and the positioning groove is configured with a conical shape.

[0010] Optionally, the sleeve is tapered.

[0011] Optionally, the sleeve is provided with a mounting groove at one end near the climbing cone, and the climbing cone is installed in the mounting groove.

[0012] Optionally, the sleeve is further provided with threaded holes distributed around the mounting groove for connection with disassembly and assembly tools.

[0013] Optionally, the end of the climbing cone away from the stressed bolt is provided with a mounting threaded hole, which is used to connect with the bolt or an installation tool.

[0014] Optionally, a magnet is also provided at one end of the sleeve facing the climbing cone, and the magnet is used to magnetically attract the pier casting mold.

[0015] Optionally, the sleeve is made of steel.

[0016] Compared with the prior art, the embedded climbing cone assembly of this utility model uses a sleeve to fit onto the stressed bolt. The two ends of the stressed bolt in the axial direction are connected to the embedded part and the climbing cone respectively. The sleeve can form a protective shell on the outside of the stressed bolt, so that the stressed bolt can be in a relatively independent space, thereby avoiding direct contact between the stressed bolt and the concrete. In this way, during the dismantling process, the stressed bolt can be directly pulled out from the sleeve, thereby improving the dismantling efficiency. Attached Figure Description

[0022] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0023] In the attached diagram, the Z-axis represents the vertical position, with the positive direction of the Z-axis (where the arrow points) indicating the top and the negative direction (opposite to the positive direction) indicating the bottom. The X-axis represents the horizontal position, with the positive direction of the X-axis (where the arrow points) indicating the right and the negative direction (opposite to the positive direction) indicating the left. It should be noted that the aforementioned representations of the Z-axis and X-axis are for ease of description and simplification only, and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on the present invention.

[0024] It should be noted that the terms "first," "second," etc., used in the specification, claims, and accompanying drawings of this utility model are used to distinguish similar objects and are not necessarily used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this utility model described herein can be implemented in sequences other than those illustrated or described herein.

[0025] Combination Figure 1 As shown, this utility model provides a pre-embedded climbing cone assembly, including a pre-embedded part 1, a load-bearing bolt 2, a sleeve 3 and a climbing cone 4. The sleeve 3 is sleeved on the load-bearing bolt 2, and the two ends of the load-bearing bolt 2 in the axial direction are respectively connected to the pre-embedded part 1 and the climbing cone 4.

[0026] Specifically, in use, the sleeve 3 is fitted onto the load-bearing bolt 2. The two ends of the load-bearing bolt 2 in the axial direction can extend out from the sleeve 3 and are connected to the embedded part 1 and the climbing cone 4 respectively. The whole assembly is fixed to the pier casting mold 10 (the pier casting mold 10 can be understood as a barrel-shaped structure surrounded by steel plates). After the concrete poured by the pier casting mold 10 has solidified, the pier casting mold 10 is removed. The embedded part 1, sleeve 3, load-bearing bolt 2 and climbing cone 4 are embedded in the concrete as a whole, realizing the installation of the embedded climbing cone assembly. The sleeve 3 forms a protective shell on the outside of the load-bearing bolt 2 and can prevent the concrete from directly contacting the load-bearing bolt 2. After the climbing cone 4 is used, rotate the climbing cone 4 to disconnect the connection between the load-bearing bolt 2 and the climbing cone 4. Then, the climbing cone 4 can be directly removed from the pier. After that, the load-bearing bolt 2 can be removed from the embedded part 1. The load-bearing bolt 2 can be directly pulled out from the sleeve 3 to avoid the load-bearing bolt 2 being difficult to disassemble due to friction between the load-bearing bolt 2 and the concrete.

[0027] Therefore, in this embodiment, the sleeve 3 is sleeved on the stressed bolt 2, and the two ends of the stressed bolt 2 in the axial direction are respectively connected to the embedded part 1 and the climbing cone 4. The sleeve 3 can form a protective shell on the outside of the stressed bolt 2, so that the stressed bolt 2 can be in a relatively independent space, thereby avoiding direct contact between the stressed bolt 2 and the concrete. In this way, during the dismantling process, the stressed bolt 2 can be directly pulled out from the sleeve 3, thereby improving the dismantling efficiency.

[0028] Optionally, combined Figures 1 to 3 As shown, the embedded part 1 is provided with a groove 11, and a positioning block 12 is provided in the groove 11. The positioning block 12 is rotatably connected to the side wall of the groove 11 by a spring. The connecting end of the force bolt 2 is provided with a positioning groove 21. The connecting end extends into the groove 11 and squeezes the spring. After the positioning groove 21 and the positioning block 12 are aligned, the spring drives the positioning block 12 to engage with the positioning groove 21.

[0029] Alternatively, the embedded part 1 is provided with a groove 11, and a positioning block 12 is provided in the groove 11. The positioning block 12 is moved on the embedded part 1 by an elastic element along the depth direction perpendicular to the groove 11. The connecting end of the force-bearing bolt 2 is provided with a positioning groove 21. The connecting end extends into the groove 11 and squeezes the elastic element. After the positioning groove 21 is aligned with the positioning block 12, the elastic element drives the positioning block 12 to engage with the positioning groove 21.

[0030] Specifically, the groove 11 is columnar in shape and located on the axis of the embedded part 1, with the opening of the groove 11 facing the positive X-axis. For example... Figure 1 and Figure 2 As shown, an installation groove is provided on the inner wall of the groove 11. The positioning block 12 is rotatably installed in the installation groove by means of a spring and can rotate in the installation groove. Part of the positioning block 12 extends into the groove 11. The connecting end of the load-bearing bolt 2 refers to the left end of the load-bearing bolt 2. The positioning groove 21 is located on the connecting end of the load-bearing bolt 2. After the connecting end of the load-bearing bolt 2 extends into the groove 11 and touches the positioning block 12, the load-bearing bolt 2 pushes the positioning block 12 to rotate clockwise and increases the elastic force of the spring. When the opening of the positioning groove 21 moves to directly below the positioning block 12, the positioning block 12 rotates counterclockwise under the action of the spring elastic force to engage with the positioning groove 21 and fix the load-bearing bolt 2 in the groove 11.

[0031] In another implementation, such as Figure 1 and Figure 3As shown, an installation groove is provided on the inner wall of the groove 11. The installation groove extends vertically and the opening of the installation groove faces the inside of the groove 11. The positioning block 12 is connected to the bottom of the installation groove through an elastic element and can move vertically. After the connecting end of the force-bearing bolt 2 extends into the groove 11 and touches the positioning block 12, the force-bearing bolt 2 pushes the positioning block 12 upward and increases the elastic force of the elastic element. When the opening of the positioning groove 21 moves to directly below the positioning block 12, the positioning block 12 moves downward under the action of the elastic force of the elastic element to engage with the positioning groove 21 and fix the force-bearing bolt 2 in the groove 11.

[0032] Thus, a groove 11 is provided on the embedded part 1, and a positioning block 12 is provided inside the groove 11. The positioning block 12 is rotatably mounted in the groove 11 by a spring. A positioning groove 21 is provided on the connecting end of the load-bearing bolt 2. The connecting end extends into the groove 11 and overcomes the elastic force of the spring to make the positioning block 12 rotate into the groove 11. After the positioning groove 21 is aligned with the groove opening of the groove 11, the spring drives the positioning block 12 to engage with the positioning groove 21. Alternatively, a groove 11 is provided on the embedded part 1, and a positioning block 12 is provided inside the groove 11. The bolt 2 is mounted on the embedded part 1 by moving the elastic element along the depth direction perpendicular to the groove 11. The connecting end of the bolt 2 is provided with a positioning groove 21. The connecting end extends into the groove 11 and overcomes the elastic force of the elastic element to move the positioning block 12 away from the groove 11. After the positioning groove 21 is aligned with the groove opening of the groove 11, the elastic element drives the positioning block 12 to engage with the positioning groove 21. In this way, the bolt 2 and the embedded part 1 can be fixed by engaging the positioning groove 21 and the positioning block 12, so as to improve the stability of the bolt 2 in use.

[0033] Optionally, a protruding strip is provided on the connecting end, and a sliding groove is also provided in the groove 11, with the protruding strip and the sliding groove being slidably connected.

[0034] Specifically, a raised strip is provided on the connecting end of the stressed bolt 2, and a sliding groove is provided on the inner wall of the groove 11. Both the raised strip and the sliding groove extend along the axial direction of the stressed bolt 2 and also along the depth direction of the groove 11. The raised strip and the sliding groove are slidably connected.

[0035] Thus, by providing a protruding strip on the connecting end and a sliding groove in the groove 11, the protruding strip and the sliding groove are slidably connected, which not only guides the axial movement of the stressed bolt 2, but also limits the circumferential movement of the stressed bolt 2, thereby improving the stability of the stressed bolt 2.

[0036] Optionally, combined Figure 2 As shown, both ends of the positioning block 12 in the depth direction of the groove 11 are set as conical structures 121, and the shape of the positioning groove 21 is set as conical.

[0037] Specifically, the depth direction of the groove 11 refers to the X-axis direction, that is, the left and right ends of the positioning block 12. Both the left and right ends of the positioning block 12 are set as conical structures 121, and correspondingly, the shape of the positioning groove 21 is set as a conical shape.

[0038] Thus, by setting both ends of the positioning block 12 in the depth direction of the groove 11 as conical structures 121, and setting the shape of the positioning groove 21 as conical, while ensuring that the positioning block 121 can engage with the positioning groove 21, the conical structure 121 can reduce the collision intensity between the stressed bolt 2 and the positioning block 121 during the process of the stressed bolt 2 being inserted into or pulled out of the groove 11, thereby improving the moving efficiency of the stressed bolt 2 and thus improving the disassembly efficiency of the stressed bolt 2.

[0039] Optionally, combined Figure 1 As shown, the sleeve 3 is set to a conical shape.

[0040] Specifically, from left to right, the diameter of sleeve 3 gradually increases. The end of sleeve 3 with a smaller diameter faces the embedded part 1, and the end of sleeve 3 with a larger diameter faces the climbing cone 4. When sleeve 3 is removed, a conical hole can be left on the pier.

[0041] Thus, by setting the sleeve 3 to a conical shape, a conical hole can be left on the pier after the sleeve 3 is removed, which can reduce the volume occupied by the sleeve 3 inside the pier, and also reduce the amount of repair materials used when repairing the pier, thereby improving the efficiency of pier repair.

[0042] Optionally, combined Figure 1 As shown, a mounting groove is provided at one end of the sleeve 3 near the climbing cone 4, and the climbing cone 4 is installed in the mounting groove.

[0043] Specifically, the mounting groove can be conical in shape. In use, the climbing cone 4 is embedded in the mounting groove, and the sleeve 3 wraps around the climbing cone 4 through the mounting groove.

[0044] Thus, by providing an installation groove at one end of the sleeve 3 near the climbing cone 4, the climbing cone 4 is installed in the installation groove, so that the sleeve 3 is fitted onto the climbing cone 4. The sleeve 3 forms a protective object on the outside of the climbing cone 4, which can provide structural protection for the climbing cone 4, so as to achieve separation between the climbing cone 4 and the bridge pier. Therefore, when dismantling the climbing cone 4, the friction between the climbing cone 4 and the bridge pier can be reduced, thereby improving the dismantling efficiency of the climbing cone 4.

[0045] Optionally, combined Figure 1 As shown, the sleeve 3 is also provided with threaded holes 31, which are distributed around the mounting groove for connection with disassembly and assembly tools.

[0046] Specifically, the threaded hole 31 is located at the end of the sleeve 3 facing the climbing cone 4. The threaded hole 31 can be distributed circumferentially around the mounting groove. In use, the sleeve 3 can be connected to the disassembly and assembly tool through the threaded hole 31. After the operator uses the disassembly and assembly tool to thread it onto the sleeve 3, it is easy to move the sleeve 3 to the use position. For example, during the transportation process, the sleeve 3 can be lifted to the top of the bridge pier using the lifting lug. Alternatively, during the disassembly process, the threaded connector can be screwed into the threaded hole 31 and the sleeve 3 can be pulled out from the bridge pier.

[0047] Thus, the sleeve 3 is also provided with threaded holes 31, which are distributed around the mounting groove for connection with disassembly and assembly tools. The threaded holes 31 enable the connection between the sleeve 3 and the disassembly and assembly tools, thereby improving the ease of use of the sleeve 3 and improving the disassembly and assembly efficiency of the sleeve 3.

[0048] Optionally, combined Figure 1 As shown, the end of the climbing cone 4 away from the stressed bolt 2 is provided with a mounting threaded hole 41, which is used to connect with the bolt or installation tool.

[0049] Specifically, the mounting threaded hole 41 is located on the axis of the climbing cone 4, and at the end of the climbing cone 4 away from the stressed bolt 2. In use, the climbing cone can be connected to the bolt or installation tool through the mounting threaded hole 41.

[0050] Thus, by providing a threaded hole 41 at the end of the climbing cone 4 away from the stressed bolt 2, the threaded hole 41 is used to connect with the bolt or installation tool, thereby realizing a threaded connection between the climbing cone 4 and the bolt or installation tool, and improving the stability of the climbing cone 4 by utilizing the self-locking property of the threaded connection.

[0051] Optionally, a magnet is also provided at the end of the sleeve 3 facing the climbing cone 4, and the magnet is used to magnetically attract the pier casting mold 10.

[0052] Specifically, during the pier construction, steel plates are used to form a columnar shape around the pier at the construction location. Concrete is then poured into the space enclosed by the steel plates. The steel plates used in this process can be understood as the pier construction mold 10. When using the pre-embedded climbing cone assembly, the magnet on the sleeve 3 can be used to magnetically attach it to the steel plate to initially fix the pre-embedded climbing cone assembly. Then, the bolts mentioned above are used to fix the climbing cone to the steel plate.

[0053] Thus, a magnet is also provided at one end of the sleeve 3 facing the climbing cone 4. The magnet is used to magnetically attract the pier casting mold 10. The magnet can realize the pre-positioning of the pre-embedded climbing cone component, thereby improving the stability of the pre-embedded climbing cone component in use.

[0054] Optionally, sleeve 3 is made of steel.

[0055] Specifically, the sleeve 3 is made of steel, and the outer surface of the supported sleeve 3 is machined into a conical structure. This improves the structural strength of the sleeve 3.

[0056] Although the present invention has been disclosed above, its protection scope is not limited thereto. Those skilled in the art can make various changes and modifications without departing from the spirit and scope of the present invention, and all such changes and modifications will fall within the protection scope of the present invention.
