[0043] Reference Figure 1-10 The image shows a preferred embodiment of the present invention.

[0044] The construction method for a recyclable prefabricated internal support system includes the following steps:

[0045] S100, a concrete support platform 200 is poured on the support piles 100 inside the foundation pit, and multiple connecting components 400 are pre-embedded on the support platform 200.

[0046] S200, multiple pads 500 are laid on the support platform 200, and the multiple pads 500 are arranged at intervals around the outer periphery of the support pile 100; the pads 500 are provided with multiple holes, and the pads 500 pass through multiple connecting members 400 through the multiple holes and abut against the top of the support platform 200; the pads 500 are detachably installed on the multiple connecting members 400 by multiple locking members 600.

[0047] S300, the support structure 300 is placed on the pad 500. The support structure 300 is arranged circumferentially around the outer periphery of the support pile 100 and abuts against the outer periphery of the support pile 100. Multiple connecting members 400 are located on both sides of the support structure 300. The pad 500 is also laid on top of the support structure 300. The pad 500 is detachably installed on the multiple connecting members 400 by multiple locking pieces 600, so that the pad 500 forms a clamping state above and below the support structure 300.

[0048] The construction method of the recyclable prefabricated internal support system provided above uses a concrete-cast support platform 200 to bear or distribute the load from the support structure 300. The support platform 200 clamps the support structure 300 with multiple pads 500, and then uses connecting members 400 and locking members 600 to fix and position the support structure 300. This allows the soil pressure received by the support pile 100 in the foundation pit to be balanced by the support structure 300, and increases the stability of the support pile 100. The support structure 300 is detachably connected to the connecting members 400 and the locking members 600, allowing for quick installation or disassembly and recycling. This solves the problem that the internal support structure cannot be reused.

[0049] The materials of the supporting structure 300 include, but are not limited to, reinforced concrete, stiffened concrete, structural steel and other materials; the cross-sectional shape of the pad 500 includes, but is not limited to, rectangular, I-shaped and other various shapes; the connecting components 400 include, but are not limited to, threaded rods 305, bolts and other various shapes; the locking components 600 include, but are not limited to, nuts 306, nuts and other various shapes.

[0050] In this embodiment, in step S300:

[0051] The support structure 300 includes a crossbeam support 301 and a longitudinal beam support 302. The longitudinal beam support 302 is located on top of the crossbeam support 301, and the crossbeam support 301 is located on top of the support platform 200. The longitudinal beam support 302 and the crossbeam support 301 are located on both sides of the support pile 100, respectively.

[0052] The pad 500 includes a lower pad 501, a middle pad 502, and an upper pad 503. The bottom of the lower pad 501 presses against the top of the support platform 200, and the top of the lower pad 501 abuts against the bottom of the crossbeam support 301. The bottom of the middle pad 502 presses against the top of the crossbeam support 301, and the top of the middle pad 502 abuts against the bottom of the longitudinal beam support 302. The upper pad 503 presses against the top of the longitudinal beam support 302.

[0053] Multiple locking elements 600 are respectively provided on the top of the lower pad 501, the middle pad 502 and the upper pad 503. The lower pad 501, the middle pad 502 and the upper pad 503 are penetrated by multiple connecting members 400, and the multiple connecting members 400 and the multiple locking elements 600 are detachably connected. The upper pad 503, the middle pad 502 and the lower pad 501 are arranged longitudinally relative to each other from top to bottom.

[0054] The layered support system divides the support structure 300 into horizontal beam supports 301 and longitudinal beam supports 302, which are stacked to increase the stability of the support piles 100. Lower pads 501, middle pads 502, and upper pads 503 are laid between the support platform 200, the horizontal beam supports 301, and the longitudinal beam supports 302 for clamping. Multiple connecting components 400 and multiple locking devices 600 are used for detachable installation, thus fixing the horizontal beam supports 301 and the longitudinal beam supports 302 onto the support platform 200. This construction process allows for rapid installation of the support system, prevents deformation, and is safer.

[0055] When the upper pad 503, the middle pad 502, and the lower pad 501 are arranged longitudinally relative to each other from top to bottom, the upper pad 503, the middle pad 502, and the lower pad 501 can be precisely penetrated by the connecting member 400, thereby increasing the installation stability of the upper pad 503, the middle pad 502, and the lower pad 501.

[0056] By using multiple connecting members 400 located on both sides of the crossbeam support 301 and the longitudinal beam support 302, the positions of the crossbeam support 301 and the longitudinal beam support 302 are restricted, thereby increasing the stability of the crossbeam support 301 and the longitudinal beam support 302.

[0057] The layered support system can be combined with cast-in-place beam support.

[0058] In this embodiment, the connecting member 400 includes an embedded section 401 inserted into the support platform 200 and an exposed section 402 exposed outside the support platform 200; the locking member 600 includes an upper locking member 601, a middle locking member 602, and a lower locking member 603. The lower locking member 603 is installed at the bottom of the exposed section 402 and abuts against the top of the lower pad 501; the middle locking member 602 is installed in the middle of the exposed section 402 and abuts against the top of the middle pad 502; the upper locking member 601 is installed at the top of the exposed section 402 and abuts against the top of the upper pad 503.

[0059] When the cast-in-place concrete support platform 200 is constructed, a connecting component 400 can be pre-embedded, so that the embedded section 401 of the connecting component 400 is formed within the support platform 200, thereby increasing the integrity of the connecting component 400 and the support platform 200. Alternatively, after the concrete support platform 200 is formed, the connecting component 400 can be inserted by drilling, thereby increasing the flexibility of the installation of the connecting component 400.

[0060] In this embodiment, the longitudinal beam support 302 and the transverse beam support 301 are arranged vertically; the upper pad 503, the middle pad 502, and the lower pad 501 are located in the intersection area between the longitudinal beam support 302 and the transverse beam support 301, respectively.

[0061] The intersection point between the longitudinal beam support 302 and the transverse beam support 301 is the intersection area. When the upper pad 503, the middle pad 502, and the lower pad 501 are in the intersection area, the connecting member 400 can precisely connect the upper pad 503, the middle pad 502, and the lower pad 501 through them, thereby increasing the support relationship between the upper pad 503, the middle pad 502, and the lower pad 501 and the longitudinal beam support 302 and the transverse beam support 301.

[0062] In this embodiment, the longitudinal beam support 302 has a longitudinal abutment surface arranged toward the support pile 100, and the longitudinal abutment surface abuts against the outer periphery of the support pile 100; the transverse beam support 301 has a transverse abutment surface arranged toward the support pile 100, and the transverse abutment surface abuts against the outer periphery of the support pile 100; the longitudinal abutment surface and the transverse abutment surface are arranged perpendicularly to each other.

[0063] The longitudinal beam support 302 can directly abut against the outer periphery of the support pile 100 through the longitudinal abutment surface, increasing the balance force and stability of the support pile 100; while the transverse beam support 301 also increases the contact area with the support pile 100 through the transverse abutment surface, increasing the balance force and stability of the support pile 100.

[0064] In this embodiment, in step S300:

[0065] The top of the support platform 200 is provided with multiple enclosure plates 101, which are arranged around the circumference of the support pile 100. Concrete is poured between the multiple enclosure plates 101 and the support pile 100. The support structure 300 abuts against the enclosure plates 101.

[0066] The bottom of one pad 500 presses against the top of the support platform 200, and the top of another pad 500 abuts against the bottom of the support structure 300; another pad 500 presses against the top of the support structure 300, and the other pad 500 and the first pad 500 are connected by multiple connecting members 400, and the multiple connecting members 400 are detachably connected to multiple locking members 600; the one pad 500 and the other pad 500 are arranged opposite each other along the horizontal longitudinal direction.

[0067] Concrete is poured between multiple enclosure plates 101 and support piles 100 to increase the connection between enclosure plates 101 and support piles 100. The enclosure plates 101 are then pressed down by the support structure 300 of the single beam support system, so that the single beam support system can also balance and stabilize the support piles 100. The support structure 300 can also be quickly installed or disassembled and recycled through the connecting component 400 and the locking component 600.

[0068] By using multiple connecting members 400 located on both sides of the support structure 300, the position of the support structure 300 is restricted, thereby increasing the stability of the support structure 300.

[0069] In this embodiment, the support structure 300 also includes a first support beam 303 and a second support beam 304. The first support beam 303 and the second support beam 304 are arranged opposite to each other. A plurality of bolt rows are provided between the first support beam 303 and the second support beam 304. The plurality of bolt rows are arranged along the length direction of the first support beam 303 and the second support beam 304, and adjacent bolt rows are staggered.

[0070] The bolt row includes multiple screws 305 arranged sequentially along the length of the first support beam 303 and the second support beam 304. The first and last ends of the screws 305 pass through the first support beam 303 and the second support beam 304 respectively, and the first and last ends of the screws 305 are detachably connected by nuts 306.

[0071] The first support beam 303 and the second support beam 304 of the double beam support system press against the enclosure plate 101, making the support pile 100 more balanced and stable. The first support beam 303 and the second support beam 304 can also be quickly installed or disassembled and recycled through the connecting component 400 and the locking component 600.

[0072] Furthermore, the connection between the first support beam 303 and the second support beam 304 via screw 305 and nut 306 makes the position and connection between the first support beam 303 and the second support beam 304 more stable, thereby increasing the balancing force on the support pile 100.

[0073] In this embodiment, there is a gap region 307 between the first support beam 303 and the second support beam 304, and the gap region 307 is greater than the width of the first support beam 303 or the second support beam 304.

[0074] The first support beam 303 and the second support beam 304 are separated by a gap 307 to increase the pressure distance on the support pile 100, thereby improving the balance force of the support pile 100.

[0075] In this embodiment, the pad 500 is provided with a plurality of limiting clamps 504 for limiting the offset of the support structure 300, and the plurality of limiting clamps 504 are located on both sides of the support structure 300 respectively; the pad 500 is provided with a track 505 for the limiting clamps 504 to slide, and the bottom of the limiting clamps 504 is located in the track 505.

[0076] The pad 500 is provided with an outer support rod 507. The bottom of the outer support rod 507 is hinged to the pad 500. The top of the outer support rod 507 presses against the limiting clamp 504. The limiting clamp 504 has multiple slots 506 for the outer support rod 507 to press against. The multiple slots 506 are arranged at intervals from top to bottom along the top of the limiting clamp 504.

[0077] When the multiple limiting clamps 504 are in the position of restricting the support structure 300, they slide on the track 505 toward the outer periphery of the support structure 300 until they press against it. When the limiting clamps 504 press against the outer periphery of the support structure 300, the outer support rod 507 presses against the slot 506 of the limiting clamps 504. The outer support rod 507 is arranged in an inclined position.

[0078] The pad 500 is adapted by clamping multiple limiting clamps 504 on both sides of the support structure 300. The outer support rod 507 is pressed against the outer end of the limiting clamp 504, while the inner end of the limiting clamp 504 is against the outer side of the support structure 300, so that the limiting clamp 504 will not shake at will.

[0079] When the size of the support structure 300 is different, the outer support rod 507 can be pressed against the position of the limiting clamp 504 by using different positions between the slots 506 and the slots 506; in this way, the pad 500 has sufficient adaptability to support structures 300 of different sizes, and can improve the accurate positioning of the support structure 300.

[0080] In this embodiment, the pad 500 is provided with an inner support rod 508, the inner support rod 508 and the outer support rod 507 are arranged side by side, the bottom of the outer support rod 507 is hinged to the pad 500, and the top of the inner support rod 508 presses against the slot 506 of the limiting clamp 504.

[0081] When the limiting clamp 504 presses against the outer periphery of the support structure 300, the outer support rod 507 and the inner support rod 508 press against the slot 506 of the limiting clamp 504 respectively, and the outer support rod 507 and the inner support rod 508 are arranged in an inclined manner.

[0082] Both the outer support rod 507 and the inner support rod 508 have contact heads that press against the slot 506, and the contact heads are provided with a friction layer that presses against the slot 506.

[0083] The pad 500 further increases the stable pressure on the limiting clamp 504 through the inner support rod 508, so as to avoid uneven force on the limiting clamp 504 during clamping; the contact head and friction layer increase the frictional resistance between the pad and the slot 506, so that the outer support rod 507 and the inner support rod 508 are not easy to detach.

[0084] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
