Description

Technical Field

[0001] The utility model relates to the technical field of supporting piles, in particular to a prefabricated concrete supporting pile with an adjustable supporting structure. Background Art

[0002] As precast piles are increasingly widely used, they have been used in many areas as components of foundation pit support structures to bear horizontal loads and suppress soil deformation. Since the outer wall of the pile body of the commonly used support piles is smooth, when it is necessary to temporarily support external structures such as steel purlins and steel supports to prevent them from falling, the corresponding support structure needs to be fixed on the outer wall of the pile body.

[0003] For example, the Chinese utility model patent with publication number CN212175802U discloses a foundation pit steel purlin support structure, which temporarily supports and fixes the steel purlin through the support structure. However, when installing the steel purlin and the steel support, it is inevitable that the height of the support structure cannot match the designed installation height of the steel purlin and the steel support. Since the existing support structure cannot adjust the position, once the height mismatch occurs, the steel purlin and the steel support cannot be effectively supported. Utility Model Content

[0033] The utility model provides the following description with reference to the accompanying drawings to help fully understand the various embodiments of the utility model as defined by the claims and their equivalents. The description includes various specific details to help understanding, but these details should be regarded as exemplary only. Therefore, those skilled in the art will recognize that various changes and modifications can be made to the various embodiments described herein without departing from the scope and spirit of the utility model.

[0034] In the description of the present invention, descriptions of orientations, such as up, down, front, back, left, right, etc., and orientations or positional relationships indicated are based on the orientations or positional relationships shown in the drawings and are only for the convenience of describing the present invention and simplifying the description. They do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation on the present invention.

[0035] It will be understood that when one element (eg, a first element) is “connected” to another element (eg, a second element), the element may be directly connected to the other element or an intervening element (eg, a third element) may be present between the element and the other element.

[0036] The embodiment of the utility model provides a precast concrete support pile with an adjustable support structure, such as Figure 1 and Figure 2 As shown, including:

[0037] The pile body 100 may be a prefabricated pipe pile, a square pile or a pile of other shapes. The pile body 100 may be a hollow pile or a solid pile, which may be used for supporting a foundation pit to bear horizontal loads and suppress soil deformation.

[0038] The bottom plate 200 is fixed to the outer side of the pile body 100 and extends in the vertical direction. Specifically, the bottom plate 200 can be embedded in the concrete structure of the pile body 100 when the pile body 100 is formed, so as to be fixedly connected with the pile body 100, or the bottom plate 200 can be reinforced to the outer side of the pile body 100 after the pile body 100 is formed;

[0039] The support structure 300 is slidably connected to the bottom plate 200 in the vertical direction. The support structure 300 is used to temporarily support external structural members such as the steel purlin 11 and the steel support 12 to prevent these external structural members from falling;

[0040] The locking member 400 is disposed on the supporting structure 300 , and is used to lock and fix the supporting structure 300 on the base plate 200 or to release the locking of the supporting structure 300 .

[0041] In this embodiment, the support structure 300 is slidably connected with the base plate 200 in the vertical direction, so the support structure 300 can be moved in the vertical direction, and then the height of the support structure 300 can be adjusted, so that the support structure 300 is adapted to the designed installation height of the steel purlin 11 and the steel support 12, thereby stably supporting the steel purlin 11 and the steel support 12. At the same time, when the locking member 400 locks and fixes the support structure 300 on the base plate 200, the support structure 300 cannot move in the vertical direction relative to the base plate 200, and the support structure 300 can maintain the adjusted height to stably support the steel purlin 11 and the steel support 12; when the locking member 400 releases the locking of the support structure 300, the support structure 300 can continue to move in the vertical direction relative to the base plate 200, and then the height of the support structure 300 can be adjusted.

[0042] In some embodiments, Figure 2-4 As shown, the support structure includes a lower support frame 310 and an upper pull frame 320. The upper pull frame 320 is located above the lower support frame 310. The lower support frame 310 is used to hold up the steel purlin 11 from the bottom, and the upper pull frame 320 can pull up the steel support 12 through a pull member 13 such as a pull rope or a pull rod. The lower support frame 310 and the upper pull frame 320 are both slidably connected to the bottom plate 200 in the vertical direction. Therefore, the lower support frame 310 and the upper pull frame 320 can be moved in the vertical direction respectively, and then the height of the lower support frame 310 and the upper pull frame 320 can be adjusted respectively, without interfering with each other, so that the entire support structure is more suitable for the design installation height of the steel purlin 11 and the steel support 12. At the same time, locking pieces 400 are provided on both the lower support frame 310 and the upper pull frame 320. The locking piece 400 on the lower support frame 310 can lock or unlock the lower support frame 310, and the locking piece 400 on the upper pull frame 320 can lock or unlock the upper pull frame 320 without interfering with each other.

[0043] Furthermore, the lower support frame 310 includes a first sliding clamp plate 311, and the upper pull frame 320 includes a second sliding clamp plate 321. The first sliding clamp plate 311 and the second sliding clamp plate 321 are both slidably connected to the bottom plate 200 in the vertical direction, thereby realizing that the lower support frame 310 and the upper pull frame 320 are both slidably connected to the bottom plate 200 in the vertical direction. The matching area between the sliding clamp plate and the bottom plate 200 is larger, and it is easier to maintain a stable sliding connection.

[0044] In this embodiment, a locking member 400 may be provided on both the first sliding clamp plate 311 and the second sliding clamp plate 321, and the locking member 400 is used to lock or unlock the first sliding clamp plate 311 and the second sliding clamp plate 321 on the bottom plate 200. Since the first sliding clamp plate 311 and the second sliding clamp plate 321 are directly slidably connected to the bottom plate 200, the locking member 400 may directly act on the first sliding clamp plate 311 and the second sliding clamp plate 321, and the structural design of the locking member 400 may be simplified.

[0045] Furthermore, if Figure 3-5 As shown, both sides of the bottom plate 200 are provided with protrusions 201 extending in the vertical direction, so that the cross section of the bottom plate 200 forms a T-shaped structure. The back side surfaces of the first sliding clamp 311 and the second sliding clamp 321 are provided with sliding grooves 301 penetrating through them in the vertical direction, and the two side walls of the sliding groove 301 are provided with blocks 302, so that the sliding groove 301 forms a T-shaped groove structure. The bottom plate 200 is set in the sliding groove 301 and can slide along the sliding groove 301, so that the first sliding clamp 311 and the second sliding clamp 321 are both slidably connected with the bottom plate 200 in the vertical direction. The two blocks 302 are respectively set between the pile body and the two protrusions 201 on both sides of the bottom plate 200, that is, one of the blocks 302 is set between the pile body and one of the protrusions 201, and the other block 302 is set between the pile body and the other protrusion 201. The cooperation between the protrusion 201 and the stopper 302 can limit the bottom plate 200 , so that the first sliding clamping plate 311 and the second sliding clamping plate 321 are difficult to separate from the bottom plate 200 , thereby maintaining a sliding connection with the bottom plate 200 .

[0046] In some embodiments, Figure 2-4 As shown, the lower support frame 310 also includes a rib plate 312 and a support plate 313 extending in the horizontal direction, the support plate 313 is connected to the first sliding clamp plate 311, and the rib plate 312 is arranged below the support plate 313 and is connected to both the support plate 313 and the first sliding clamp plate 311. The support plate 313 is used to temporarily place the steel purlin 11 and the steel support 12, and the rib plate 312 provides an auxiliary support to reinforce the support plate 313 so that it can stably support the steel purlin and the steel support.

[0047] In this embodiment, the first sliding clamping plate 311, the rib plate 312 and the supporting plate 313 can be connected in one piece, which is convenient for manufacturing and forming the lower support frame 310 and can also improve the structural strength of the connection between them.

[0048] In some embodiments, Figure 2-4 As shown, the upper pull frame 320 also includes a hanging plate 322, which is connected to the second sliding clamp plate 321, and the hanging plate 322 is provided with a penetrating hanging hole 323. The pull member 13 such as a pull rope or a pull rod can be tied or hooked in the hanging hole 323, so that the pull member 13 is stably fixed on the upper pull frame 320.

[0049] In this embodiment, the second sliding clamping plate 321 and the hanging plate 322 can be connected in one piece, which is convenient for manufacturing and forming the upper pull frame 320 and can also improve the structural strength of the connection between them.

[0050] In some embodiments, Figure 3 and Figure 6As shown, the locking member 400 is a latch, the supporting structure is provided with a through hole that penetrates the structure and matches the latch, and the bottom plate 200 is provided with a plurality of insertion holes 210 distributed in the vertical direction. The latch is inserted into the through hole, and when the supporting structure moves in the vertical direction, the through hole on the supporting structure can dock with the insertion hole 210. When the latch is inserted into the insertion hole 210, the supporting structure cannot move in the vertical direction, and the locking member locks and fixes the supporting structure on the bottom plate 200; when the latch moves out of the insertion hole 210, the locking member releases the locking of the supporting structure, and the supporting structure can continue to move in the vertical direction. The method of inserting the latch into the insertion hole to lock or release the locking of the supporting structure has a simple structure and is more convenient to operate.

[0051] When the support structure includes the lower support frame 310 and the upper support frame 320, the first sliding clamp plate 311 and the second sliding clamp plate 321 may be provided with through holes, and correspondingly, the through holes on the first sliding clamp plate 311 and the second sliding clamp plate 321 are provided with latches, so as to lock the first sliding clamp plate 311 and the second sliding clamp plate 321 or release the locking of the first sliding clamp plate 311 and the second sliding clamp plate 321 through the respective latches. Figure 5 For example, the through hole 303 passes through the first sliding clamping plate 311 .

[0052] Furthermore, the sockets 210 are connected in sequence along the vertical direction, and the spacing between adjacent sockets 210 is equal. In this way, the spacing between adjacent sockets 210 is smaller, and the number of sockets 210 that the plug can be inserted into is greater, so as to more finely adjust the position of the support structure in the vertical direction. At the same time, a plurality of plugs are provided and are sequentially connected in the vertical direction as a group. The group of plugs can be inserted into the plurality of sequentially connected sockets 210. Multiple plugs can be inserted at one time, which can improve the structural strength of the group of plugs, making it difficult for the plugs to bend or break, and ensuring that the support structure is locked and fixed on the bottom plate 200.

[0053] In some embodiments, Figure 2-4 As shown, a limit member 220 is also provided at the lower end of the base plate 200 for limiting the support structure from detaching from the base plate 200, so that the support structure maintains a sliding connection with the base plate 200, preventing the support structure from sliding off the base plate 200 due to its own weight, and preventing the support structure from falling off and causing casualties.

[0054] In this embodiment, the limiting member 220 may be perpendicular to the bottom plate 200 and extend toward the front side of the bottom plate 200 , and may specifically be a limiting plate, a limiting block or other limiting structures.

[0055] In some embodiments, Figure 1-4 As shown, the bottom plate 200 is provided with a through installation hole 230 , and a bolt is passed through the installation hole 230 , and the bolt is anchored on the pile body 100 to achieve installation and fixation of the bottom plate 200 .

[0056] The terms and words used in the above description and claims are not limited to the literal meanings, but are only used by the applicant to enable a clear and consistent understanding of the utility model. Therefore, it should be clear to those skilled in the art that the above description of various embodiments of the utility model is provided only for illustration, and not for limiting the utility model as defined by the attached claims and their equivalents.
