Description

Technical Field

[0001] This utility model relates to the field of cast-in-place pile construction technology, and in particular to a support frame for the borehole of a cast-in-place pile. Background Technology

[0002] A cast-in-place pile is a type of pile foundation formed by drilling a hole to a designed depth in the ground using mechanical or manual methods, then placing a reinforcing cage inside the hole and continuously pouring concrete (or cement grout). Its core characteristic is "drilling first, then pouring," making it a type of deep foundation constructed on-site. During cast-in-place pile construction, a casing 200 is placed in the area where the pile will be formed before drilling, placing the reinforcing cage 300 inside the hole, and finally pouring the concrete. Here, the top of the casing 200 is above ground level. In actual construction, the top of the reinforcing cage 300 needs to be higher than the top of the casing 200. Since the reinforcing cage 300 is not necessarily placed at the bottom of the borehole, it needs to be supported. However, currently, there is no reusable and reliable support frame for the borehole opening of a cast-in-place pile.

[0003] Therefore, there is an urgent need to propose a simple, reliable, and reusable support frame for the borehole of cast-in-place piles. Utility Model Content

[0004] To address the aforementioned problems, the purpose of this utility model is to provide a support frame for the borehole of a cast-in-place pile. The technical solution adopted by this utility model is as follows:

[0005] A support frame for a cast-in-place pile borehole is placed on the ground where the pile is to be cast and supports the reinforcing cage. A protective casing is placed in the ground; a borehole is drilled inside the casing; the reinforcing cage is placed into the borehole. The support frame for the cast-in-place pile borehole includes a support frame assembly placed on the ground, and several reinforcing cage hook assemblies set on the support frame assembly for hanging the reinforcing cage; the support frame assembly includes an integrally formed annular support ring and an upper ring, several T-shaped lower supports set at the lower part of the annular support ring, several locking grooves opened on the inner side of the annular support ring and the upper ring, and support blocks welded to the upper ring and respectively placed on both sides of the locking grooves; the reinforcing cage hook assembly includes hooks whose upper ends are locked in the locking grooves for hanging the reinforcing cage, and a crossbeam set above the hooks and below the support blocks.

[0006] Furthermore, a square groove is provided on the inner side of the T-shaped lower support; a protective sleeve extrusion assembly is pressed between the protective sleeve and the square groove.

[0007] Furthermore, the sleeve extrusion assembly includes a rear support block placed in a square groove, a screw connected to the rear support block, a sleeve sleeved on the screw, an adjusting nut threaded onto the screw and pressed against the sleeve, and a front extrusion plate disposed on the sleeve and attached to the sleeve.

[0008] Compared with the prior art, the present invention has the following beneficial effects:

[0009] (1) This utility model supports the annular support ring and the upper ring by setting several T-shaped lower brackets, so as to hang the rebar cage hook assembly and ensure that the rebar cage is reliably installed in the casing; in addition, this utility model opens the locking groove on the annular support ring and the upper ring, and sets the support blocks on both sides of the locking groove, so as to reliably hang the rebar cage hook assembly.

[0010] (2) This utility model sets up hooks and crossbeams to support the steel cage, while not affecting the grouting operation inside the casing.

[0011] (3) By setting up a square groove and a protective cylinder extrusion assembly, the present invention extrudes the protective cylinder onto the surface of the protective cylinder, ensuring that the support frame assembly and the steel cage hook assembly are supported more reliably.

[0012] In summary, this utility model has the advantages of simple structure, reliable support, and reusability, and has high practical and promotional value in the field of cast-in-place pile construction technology. Attached Figure Description

Any embodiment or design that is described as "exemplary" or "for example" in the embodiments of this application should not be construed as being more preferred or advantageous than other embodiments or design. Specifically, the use of the terms "exemplary" or "for example" is intended to present the relevant concepts in a specific manner.

[0027] In the description of the embodiments in this application, unless otherwise stated, "multiple" means two or more. For example, multiple processing units means two or more processing units; multiple systems means two or more systems.

[0028] like Figures 1 to 7As shown, this embodiment provides a pile borehole support frame, which is placed on the ground 100 where the pile is to be cast and supports the reinforcing cage 300. Specifically, a casing 200 is inserted into the area where the pile is to be cast, then a hole is drilled, and the reinforcing cage 300 is placed inside the hole before final pouring. Here, the pile borehole support frame supports the reinforcing cage 300 and helps prevent the casing 200 from sinking.

[0029] Here, the grouting pile borehole support frame includes a support frame assembly 1 placed on the ground 100, several steel cage hook assemblies 2 set on the support frame assembly 1 and for hanging the steel cage 300, and a casing compression assembly 3 pressed between the support frame assembly 1 and the casing 200.

[0030] Here, the support frame assembly 1 includes an integrally formed annular support ring 11 and an upper ring 13, several T-shaped lower supports 12 disposed at the lower part of the annular support ring 11, several locking grooves 14 formed on the inner side of the annular support ring 11 and the upper ring 13, support blocks 15 welded to the upper ring 13 and respectively placed on both sides of the locking grooves 14, and square grooves 16 formed on the inner side of the T-shaped lower supports 12. The rebar cage hook assembly 2 includes a hook 21 whose upper end is locked in the locking groove 14 and which hangs the rebar cage 300, and a crossbeam 22 disposed above the hook 21 and below the support blocks 15. Here, the hook 21 is hung on the transverse rebar of the rebar cage 300 above the top of the casing 200.

[0031] In this embodiment, the casing compression assembly 3 is compressed between the casing 200 and the square groove 16. It includes a rear support block 31 placed within the square groove 16, a screw 32 connected to the rear support block 31, a sleeve 34 sleeved on the screw 32, an adjusting nut 33 threaded onto the screw 32 and compressed onto the sleeve 34, and a front compression plate 35 disposed on the sleeve 34 and fitted to the casing 200. Here, by rotating the adjusting nut 33 and extending / retracting the adjusting sleeve 34 and screw 32, several casing compression assemblies 3 are reliably compressed between the T-shaped lower support 12 and the casing 200. In this embodiment, after the cast-in-place pile has been poured, solidified, and cured, the support frame assembly 1, the rebar cage hook assembly 2, and the casing compression assembly 3 can be removed for reuse. Furthermore, for ease of disassembly, the T-shaped lower support 12 in this embodiment can be telescopically fixed using methods such as pins or pin holes. The disassembly process is as follows: Adjust the T-shaped lower bracket 12 downward so that the hook 21, crossbeam 22 disengage from the locking groove 14 and the support block 15, then the rebar cage hook assembly 2 can be removed and the protective cylinder compression assembly 3 can be released.

[0032] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Any changes made based on the design principles of this utility model, or any non-creative changes made on this basis, shall fall within the scope of protection of this utility model.
