[0033] To make the objectives, technical solutions, and advantages of the embodiments of the present disclosure clearer, the following will clearly and completely describe the technical solutions of the embodiments of the present disclosure with reference to the accompanying drawings of the embodiments of the present disclosure. Apparently, the described embodiments are part of the embodiments of the present disclosure, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present disclosure without creative efforts shall fall within the scope of protection of the present disclosure.

[0034] Please refer to Figures 1-9 , a novel fully prefabricated caisson provided by an embodiment of the present invention includes a box body 2 for connecting between two support members 1, and further includes: a box body 3 disposed on the outer sidewall of the box body 2, with a connecting member 4 movably disposed therein, and a connection groove 5 matching the connecting member 4 is provided on the support member 1; a driving member 6 disposed on the box body 3 for driving the connecting member 4 to extend out of the box body 3 and then insert into the connection groove 5, and at the same time limiting the extended connecting member 4.

[0035] Specifically, the supporting member 1 can be a beam or a wall, and the upper end of the supporting member 1 is provided with protruding bent steel bars. The box body 2 includes a precast bottom plate and side plates surrounding the four sides of the bottom plate. The box body 2 is a concrete steel structure, and the structural steel bars it contains are all arranged within the thickness range of the box body 2 without protruding from the outer surface of the box body 2. A groove is provided on one side of the box body 2 corresponding to the supporting member 1, and the height of the groove corresponds to that of the bent steel bars at the upper end of the supporting member 1. After building components such as floor slabs are erected on the supporting member 1 and formwork is laid, the post-cast strip is then poured to synchronously fill the concrete, so as to form a stable connection with uneven embedding between the box body 2 and the subsequently installed building components. A through groove is opened on the side plate of the box body 2 close to the supporting member 1, and the box body 3 is buried and fixed in the through groove. One end face of the box body 3 facing the supporting member 1 is open, while the other end faces are retained. The connecting member 4 can extend out of the box body 3 from the open side of the box body 3. The maximum length of the connecting member 4 extending out of the box body 3 is less than its overall length, that is, when the connecting member 4 extends out of the box body 3 at the maximum extension length, one end still remains inside the box body 3, so that a transition connection structure is formed between the inside of the box body 3 and the inside of the connection groove 5 for the connecting member 4. The connection groove 5 is opened on the side of the supporting member 1 close to the box body 2 and corresponds to the box body 3 and the connecting member 4 one by one. The upper end of the connection groove 5 is open. The driving member 6 is connected to one end wall of the box body 3 away from the connection groove 5. The driving member 6 mainly drives the connecting member 4 to extend out of the box body 3 in a pushing manner, and the driving member 6 can automatically position at any position during the pushing process, thereby restricting the connecting member 4 from moving back, that is, restricting the extension of the connecting member 4. In the actual use of this technical solution, the connecting member 4 first remains retracted into the box body 3, and then the hoisting device horizontally and stably suspends the box body 2 between two supporting members 1 so that the box body 3 corresponds to the connection groove 5 one by one. Then, the driving member 6 drives the connecting member 4 to extend out of the box body 3 and then insert it into the connection groove 5. When the connecting member 4 extends to the maximum extension length, the driving member 6 synchronously limits the extended connecting member 4. At this time, both ends of the connecting member 4 are respectively located inside the box body 3 and inside the connection groove 5. Then the hoisting device completely releases the box body 2, and the connecting member 4 can support downward in the connection groove 5 and support the box body 2 between the two supporting members 1. Thus, there is no need to leave protruding steel bars outside the box body 2. Since there are no protruding steel bars outside the box body 2, the side molds used for prefabricating the box body 2 do not need to consider the penetration of steel bars, and the structural design is simpler, facilitating prefabrication production. Since there are no protruding steel bars outside the box body 2, the overall occupied space of the precast caisson can be greatly reduced, thus facilitating transportation and reducing the safety hazards caused by protruding steel bars to workers. Since there are no protruding steel bars outside the box body 2, when assembling the box body 2 at the construction site, there is no need to consider the interference problem with the stressed steel bars of other building components, facilitating assembly and reducing the calculation amount for the construction layout.

[0036] Compared with the prior art, a novel fully precast caisson proposed in the embodiment of the present invention is provided with a connecting member 4 on the box body 2 and a connecting groove 5 on the supporting member 1. When the box body 2 is assembled, it is first suspended between two supporting members 1 by a hoisting device. Then, the driving member 6 drives the connecting member 4 to extend outwards from the box body 3 and then insert into the connecting groove 5. At the same time, the extended connecting member 4 is limited. Then, the hoisting device completely releases the box body 2, and the box body 2 can be supported between the two supporting members 1 without leaving extended steel bars on the outer side of the box body 2, thus facilitating the production, transportation, and construction assembly of the precast caisson.

[0037] As a preferred technical solution of this embodiment, a plurality of box bodies 3 are provided, and at least two are arranged on opposite sides of the box body 2 on each side. Specifically, the plurality of box bodies 3 on the same side of the box body 2 are horizontally arranged evenly and are arranged close to the vertical edge of the box body 2. Thus, when a supporting effect is formed between the connecting member 4 in the box body 3 and the supporting member 1, the box body 2 can be supported at more points and within a larger range, making the box body 2 more stable after assembly.

[0038] As a preferred technical solution of this embodiment, a plurality of connecting bars 7 are arranged on the outer side of the box body 3, and the connecting bars 7 are anchored in the box body 2. Specifically, the connecting bars 7 are anchored within the thickness range of the side plate of the box body 2; during the prefabrication process of the box body 2, the box body 3 is arranged within the structural steel bar framework of the box body 2 and is fixedly connected by binding between the connecting bars 7 on the box body 3 and the structural steel bars of the box body 2. During the prefabrication production process of the box body 2: First, the structural steel bar framework of the box body 2 is erected, then the box body 3 is arranged within the structural steel bar framework, and the connecting bars 7 on the box body 3 are bound and fixed to the structural steel bar framework. After that, a precast formwork of the box body 2 is arranged around the structural steel bar framework, and then concrete is filled into the precast mold. After the concrete is vibrated and solidified, the connecting bars 7 are anchored and connected to the box body 2, that is, the box body 3 is fixed on the box body 2.

[0039] As a preferred technical solution of this embodiment, the connecting member 4 is set as a plate body, and sliding rails 8 matching the plate body are arranged on both the inner top surface and the inner bottom surface of the box body 3. Specifically, the plate body is vertically arranged inside the box body 3, and the height of the plate body is consistent with the distance between the upper and lower two sliding rails 8; the sliding rails 8 are composed of two parallel and juxtaposed convex strips fixed on the inner wall of the box body 3, and the width between the two convex strips is consistent with the thickness of the plate body; the vertical plate body has a relatively high vertical supporting strength to meet the support for the box body 2; the plate body moves horizontally along the sliding rails 8.

[0040] As a preferred technical solution of this embodiment, the driving member 6 is arranged as a screw rod, and the screw rod penetrates through and is threadedly connected to the box body 3. One end of the screw rod extending into the box body 3 abuts against the connecting member 4. Specifically, another nut is fixedly connected to one end wall of the box body 3 away from the connecting groove 5. The screw rod penetrates through and is threadedly connected to the nut, and the head is arranged outside the box body 3, and the foot abuts against the connecting member 4; the movement trajectory generated by the screw feed action between the screw rod and the nut through rotation coincides with the trajectory of the connecting member 4 moving along the slide rail 8. In actual use of this technical solution, when the box body 2 is suspended between the two support members 1 driven by a hoisting device and the box body 3 corresponds to the connecting groove 5 one by one, a tool is used to rotate the screw rod, and the screw rod and the box body 3 have a screw feed action. The screw rod continuously extends into the box body 3. At the same time, the foot of the screw rod pushes the connecting member 4 to extend and move out of the box body 3. When the connecting member 4 extends out of the box body 3 to the maximum extension length, that is, the extended end of the connecting member 4 abuts against the inner wall of the connecting groove 5, the screw rod stops rotating, thereby automatically limiting the connecting member 4 and making the connecting member 4 stably located between the inside of the box body 3 and the inside of the connecting groove 5.

[0041] As a preferred technical solution of this embodiment, a grouting hole 9 communicating with the inside of the box body 3 is provided at the upper end of the box body 2. Specifically, a through hole is opened at the upper end of the box body 3, and the through hole belongs to a part of the grouting hole 9. The grouting hole 9 is arranged corresponding to the upper side of one end of the box body 3 away from the connecting groove 5. In actual use of this technical solution, after the box body 2 completes the lapping and assembly with the connecting groove 5 by means of the connecting member 4, it is necessary to pour slurry into the box body 3 and the connecting groove 5 to strengthen the connection. On the one hand, the slurry is directly poured into the connecting groove 5 with an open upper end, and then because the inside of the box body 3 is communicated with the connecting groove 5 at this time, the slurry can also be automatically filled into the box body 3. However, because the depth inside the box body 3 is far from the upper opening of the connecting groove 5, there is a problem that the slurry filling is not sufficient. On the other hand, the slurry can be supplemented into the box body 3 through the grouting hole 9, so as to completely fill the inside of the box body 3 with slurry. After waiting for the slurry to solidify, the connection between the box body 3 and the connecting groove 5 is ensured to be stable.

[0042] In another embodiment proposed by the present invention, a wing plate 10 is provided on the connecting member 4, and a bolt 11 is threadedly connected to the wing plate 10. The bolt 11 can extend into the connecting groove 5 along with the connecting member 4. Specifically, the wing plate 10 penetrates through the connecting member 4, that is, both ends of the wing plate 10 extend out on opposite sides of the connecting member 4. The width of the wing plate 10 is not greater than the width of the inner wall of the box body 3, so that the wing plate 10 can be received into the box body 3 along with the connecting member 4; the wing plate 10 is horizontally arranged, and nuts are fixedly connected to the upper sides of both ends thereof. The bolt 11 passes through and is threadedly connected to the nuts and is arranged vertically; the vertically arranged bolt 11 can be lifted or lowered through the thread feed action occurring between the rotation of the bolt 11 and the nuts; the height of the lower surface of the connecting member 4 is within the lifting range of the lower end of the bolt 11, so that the bolt 11 can support the connecting member 4 in the connecting groove 5 by descending. The liftable setting of the bolt 11 and its ability to support the connecting member 4 enable fine adjustment of the height of the connecting member 4 in the connecting groove 5. In actual use of this technical solution, since the box body 2 is supported by the connecting members 4 in multiple box bodies 3, and the height positions of the box bodies 3 on the box body 2, due to errors existing in the prefabrication process, such as the driving during the concrete pouring process or the minor morphological changes during the concrete solidification process, it is difficult for multiple box bodies 3 to maintain the same horizontal height. In addition, there may also be height errors in the connecting grooves 5 on the support member 1. Therefore, there are still problems in the horizontal assembly of the box body 2. In view of this, the setting of the bolt 11 can, after the connecting member 4 is inserted into the connecting groove 5 and supports the box body 2, find the side with a lower height of the box body 2 under the detection of an external level, and then adjust the support structure on this side, that is, rotate the bolt 11 at the corresponding position through a tool to make the bolt 11 have a thread feed action with the wing plate 10. The bolt 11 slowly descends, first abuts against the inner bottom surface of the connecting groove 5, and then gradually supports the connecting member 4, so as to realize fine adjustment of the height of the connecting member 4 in the connecting groove 5, which is beneficial to accurately position the box body 2 in a horizontal state for support and assembly. In addition, before the box body 2 is assembled, the connecting member 4 is received into the box body 3. At this time, the wing plate 10 and the bolt 11 are also located in the box body 3. By rotating the bolt 11, the bolt 11 descends under the thread feed action to abut and press against the inner bottom surface of the box body 3, so as to limit the sliding of the connecting member 4 in the box body 3 and prevent the connecting member 4 from protruding out of the box body 3 before the construction and assembly of the box body 2; and when it is necessary to push the connecting member 4 out of the box body 3, first reverse the bolt 11 to release its abutting limit against the inner bottom surface of the box body 3.

[0043] In another embodiment proposed by the present invention, a frame plate 12 is movably arranged in the connecting groove 5. One side of the frame plate 12 abuts against the side wall of the box body 2. Specifically, the frame plate 12 is arranged in a "U" shape and keeps fitting with the inner wall of the connecting groove 5. The height of the upper end of the frame plate 12 is not lower than the overall height of the box body 3. The size of the frame plate 12 can be completely received in the connecting groove 5. In actual use, when the box body 2 is assembled between the two support members 1, due to the position deviation of the box body 3 during the prefabrication of the box body 2 or the height deviation of the connecting groove 5, there is a problem that it cannot be directly horizontally assembled. In order to adjust this horizontal assembly problem, there is a part of adjustable gap between the box body 2 and the support member 1, and the box body 2 is prevented from being stuck. However, the setting of this gap also causes the problem of slurry leakage during the grouting operation after the connecting member 4 is docked with the connecting groove 5. In view of this, the frame plate 12 is arranged by fitting in the connecting groove 5, and one side abuts against the outside of the box body 2. At the same time, the inside can correspond to the opening surface of the box body 3, so as to form a transition sealing bridge between the box body 3 and the connecting groove 5, ensuring the sealing of the bottom surface and the two side surfaces communicating between the inside of the box body 3 and the inside of the connecting groove 5, thus eliminating the problem of slurry leakage during grouting caused by the gap between the support member 1 and the box body 2 mentioned above.

[0044] As a preferred technical solution of this embodiment, a slope 13 corresponding to the bolt 11 is arranged on the inner bottom surface of the frame plate 12. The slope 13 gradually decreases in height from the side close to the box body 2 to the side inside the connecting groove 5. Specifically, as Figure 4, the slope 13 is in a wedge-shaped fit with the lower end of the bolt 11. That is, when the lower end of the bolt 11 fits against the slope 13 and moves downward relatively, relative lateral movement can occur between the two. In the actual use of this technical solution, the frame plate 12 is first arranged in the connecting groove 5 in a manner that completely fits against the inner wall of the connecting groove 5, that is, the side for abutting against the box body 2 does not protrude from the connecting groove 5. Then, the box body 2 is suspended between the two support members 1. The connecting member 4 is inserted into the connecting groove 5, and the box body 2 is no longer suspended. The box body 2 is supported between the two support members 1 through the connecting member 4. Then, the connecting member 4 presses down on the frame plate 12, and the bolt 11 corresponds to the slope 13. Next, a tool is used to rotate the bolt 11, and the bolt 11 moves downward so that its lower end contacts the upper inclined surface of the slope 13. When the bolt 11 continues to move downward, under the action of the gravity of the box body 2 and the influence of the function that the frame plate 12 can move in the connecting groove 5, relative sliding occurs between the lower end of the bolt 11 and the slope 13, so that the height of the connecting member 4 in the connecting groove 5 does not change first, while the frame plate 12 translates in the direction close to the box body 2 to abut against the side of the box body 2, thereby forming a transition sealing bridge between the box body 3 and the connecting groove 5. In addition, after the frame plate 12 abuts against the box body 3, the reaction force of the slope 13 on the bolt 11 drives the connecting member 4 to tightly abut against the inner wall of the connecting groove 5 through the wing plate 10. That is, there is no need for the screw rod to limit the position of the connecting member 4, and the screw rod can be disassembled and recycled. The use of screw rod-like parts is reduced, and the cost is lowered. Moreover, after the screw rod leaves, the hole left on the box body 3 can be plugged with a plug with a lower cost. Further, when it is necessary to adjust the relative height of the connecting member 4 in the corresponding connecting groove 5, since the frame plate 12 abuts against the side wall of the box body 2 and is fixed, the bolt 11 no longer has a relative position in the horizontal direction with the slope 13. By continuing to rotate the bolt 11, the connecting member 4 can be lifted to achieve height adjustment.

[0045] In yet another embodiment proposed by the present invention, a rotating block 14 is rotatably connected to one side of the box body 3 away from the connecting groove 5. A threaded hole 15 matching the screw rod is provided in the rotating block 14. A limiting component for restricting the rotation of the rotating block 14 relative to the box body 3 is provided on the rotating block 14. A plurality of columns 16 are provided on the rotating block 14. Specifically, a concave ring groove is provided on the outer periphery of one end of the rotating block 14, and a circular hole is provided on the box body 3. A convex ring matching the concave ring groove is provided on the inner wall of the circular hole. The rotating block 14 is rotatably connected to the box body 3 by means of the concave ring groove and the convex ring, and no axial movement occurs; the other end of the rotating block 14 extends into the box body 3, and a plurality of columns 16 are fixedly connected to the circumference of this end of the rotating block 14. The threaded hole 15 penetrates through the rotating block 14; the screw rod rotates to have a threaded feeding effect with the threaded hole 15 to perform axial movement. By restricting the rotation of the rotating block 14 relative to the box body 3, the limiting component can smoothly have a threaded feeding effect with the threaded hole 15 by rotating the screw rod; by canceling the restriction on the rotating block 14, the rotating block 14 can rotate in the box body 3, and the rotation of the rotating block 14 can drive each column 16 to rotate in the box body 3. Thus, after pouring the slurry in the box body 3, the slurry can be vibrated to eliminate the air bubbles in the slurry filled in the box body 3, ensuring that the slurry is filled sufficiently and densely.

[0046] As a preferred technical solution of this embodiment, the limiting component includes a plug hole 17 provided at one end of the rotating block 14 facing the outside of the box body 3. A movable piece 18 is movably provided in the plug hole 17. A plurality of limiting rods 19 that movably penetrate through the rotating block 14 are provided on the outer peripheral surface of the movable piece 18. A circular ring 20 sleeved on the outside of the rotating block 14 is provided on the inner wall of the box body 3. A limiting groove 21 matching the limiting rods 19 is provided on the circular ring 20. Specifically, the inner diameter of the plug hole 17 is not less than the inner diameter of the threaded hole 15, and the plug hole 17 is coaxially communicated with the threaded hole 15. The movable piece 18 can perform axial movement in the plug hole 17; a hole is opened in the center of the movable piece 18, and the size of the hole is not less than the outer diameter of the screw rod. The limiting rods 19 are arranged along the radial direction of the plug hole 17, and the limiting rods 19 limit the rotation of the movable piece 18 in the plug hole 17, that is, the limiting rods 19 rotate synchronously with the rotating block 14. The range of movement of the movable piece 18 driving the limiting rods 19 can make the limiting rods 19 engage with or disengage from the limiting groove 21. In actual use of this technical solution, the limiting rods 19 first remain embedded in the limiting groove 21. Then, the rotating block 14 cannot rotate relative to the box body 3 under the restriction of the limiting rods 19 and the limiting groove 21. At this time, the screw rod can be inserted into the plug hole 17 and pass through the movable piece 18 to be threadedly connected with the threaded hole 15. Then, by rotating the screw rod, it can have a threaded feeding effect with the threaded hole 15 and perform axial movement to push the connecting piece 4; when the connecting piece 4 is smoothly inserted into the connecting groove 5 and the connecting piece 4 is limited by the bolt 11 and the slope 13, reverse the screw rod to remove it, and then plug a plug in the plug hole 17 to block it; then move the movable piece 18 in the plug hole 17 and drive the limiting rods 19 away from the circular ring 20 to make the limiting rods 19 disengage from the limiting groove 21, and the rotating block 14 can then resume rotating relative to the box body 3.

[0047] As a preferred technical solution of this embodiment, the limiting component includes a elastic piece 22 arranged on the inner wall of the plug hole 17 and a first hook body 23 arranged on the side wall of the limiting rod 19. A second hook body 24 is arranged on the elastic piece 22. The elastic piece 22 is freely unfolded and drives the second hook body 24 to remain hooked to the first hook body 23. Specifically, one end of the elastic piece 22 is fixed to the inner wall of the plug hole 17 and is far from the movable piece 18, and the other end warps into the plug hole 17 and is close to the movable piece 18. The warped end of the movable piece 18 does not contact and interfere with the screw rod passing through the threaded hole 15 in the freely unfolded state; one end of the first hook body 23 is fixedly connected to the side wall of the limiting rod 19, and the other end is set as a hook-shaped end; one end of the second hook body 24 is fixedly connected to the warped end of the movable piece 18, and the other end is also set as a hook-shaped end; the first hook body 23 and the second hook body 24 are hooked, so that the movable piece 18 remains close to the elastic piece 22, that is, the movable piece 18 drives the limiting rod 19 to remain close to the circular ring 20 and be embedded in the limiting groove 21, thereby restricting the rotation of the rotating block 14; and when the elastic piece 22 is squeezed and its warped end approaches the inner wall of the plug hole 17, it drives the second hook body 24 to disengage from the first hook body 23, then the movement of the limiting rod 19 is no longer restricted, and the movable piece 18 can move in the plug hole 17, and then it can drive the limiting rod 19 to disengage from the limiting groove 21 to restore the rotation of the rotating block 14 in the box body 3.

[0048] As a further preferred technical solution of this embodiment, the plug hole 17 is used to insert a rubber plug 25. A groove 26 matching the elastic piece 22 is arranged on the outer wall of the rubber plug 25. A torque hole 27 is arranged on the rubber plug 25. Specifically, when the rubber plug 25 is inserted into the plug hole 17, the groove 26 corresponds to the position of the elastic piece 22, but still squeezes the warped end of the elastic piece 22 with its inner wall, so as to restore the movement of the movable piece 18 and no longer block the rubber plug 25. The rubber plug 25 can further push the movable piece 18 into the deep part of the plug hole 17, so that the movable piece 18 can drive the limiting rod 19 to leave the limiting groove 21 to cancel the rotation limit of the rotating block 14. At the same time, the rubber plug 25 can tightly and completely block the plug hole 17, and by embedding the elastic piece 22 into the groove 26, the rubber plug 25 is synchronized with the rotation of the rotating block 14; the torque hole 27 is used to connect torque output devices such as electric drills. When the rotation limit of the rotating block 14 is cancelled, the electric drill and other torque output devices are inserted into the torque hole 27 and then started to drive the rubber plug 25 to rotate. The rubber plug 25 drives the rotating block 14 to rotate, and the rotating block 14 can drive the column 16 thereon to rotate to vibrate the slurry in the box body 3.
