[0029] like Figure 1 As shown, this embodiment provides a prefabricated toilet caisson connection structure, including a prefabricated toilet caisson unit, a cast-in-place beam 1, a clamping unit 2, and a water stop assembly:
[0030] Among them, the prefabricated toilet caisson unit includes a caisson body 3, and an embedded reinforcement assembly arranged on the caisson body 3; the cast-in-place beam 1 is cast on the periphery of the caisson body 3, and the embedded reinforcement assembly is buried therein; the clamping unit 2 is cast on the inner side of the cast-in-place beam 1 to increase the contact area between the cast-in-place beam 1 and the caisson body 3; the water-stop assembly is arranged circumferentially along the top of the caisson body 3 to prevent water leakage from the top of the caisson body 3.
[0031] In the prior art, there are generally two methods for connecting prefabricated caissons to the main structure. One is that the steel bars at both ends of the caisson are inserted deep into the cast-in-place ears, and anti-leakage measures are taken on the side walls of the caisson. The other is that the steel bars on the bottom plate of the caisson are inserted deep into the cast-in-place beams or walls, and there are no anti-leakage measures on the side walls. In the first method, the prefabricated caisson is not sufficiently bonded to the cast-in-place concrete part, and the whole is unstable, which is not conducive to the transmission of horizontal earthquake effects on the floor. The latter has poor anti-seepage effect. In the utility model, the embedded reinforcement assembly provided on the caisson body 3 is embedded in the cast-in-place beam 1, so that the caisson body 3 and the cast-in-place beam 1 are more firmly fitted, which is conducive to the horizontal force transmission of the floor during earthquakes; the clamping unit 2 cast on the inner side of the cast-in-place beam 1 can increase the contact area between the cast-in-place beam 1 and the caisson body 3; at the same time, the water-stop assembly arranged circumferentially along the top of the caisson body 3 makes it have a better anti-seepage effect.
[0032] Preferably, the caisson body 3 comprises a caisson bottom plate 31 and a caisson flange 32 arranged circumferentially along the caisson bottom plate 31 ; the caisson flange 32 is provided with a caisson flange rectangular notch inwardly.
[0033] Furthermore, the caisson bottom plate 31 and the caisson flange 32 arranged along the circumference of the caisson bottom plate 31 form a caisson body 3; the cast-in-place beam 1 and the building floor slab enclose a cavity, in which the caisson body 3 is placed, and the caisson body 3 is close to the side wall of the cast-in-place beam 1; a caisson flange rectangular notch is opened inward at the upper part of the caisson flange 32, so that the upper part of the caisson flange 32 has a circle of platform.
[0034] Preferably, the clamping unit 2 comprises a horizontal lug 21 cast on the inner side of the cast-in-place beam 1 , and one end of the horizontal lug 21 away from the cast-in-place beam 1 is provided with a lower hanging lug 22 adapted to the rectangular notch of the caisson flange.
[0035] Furthermore, the horizontal cantilever 21 and the lower hanging cantilever 22 form a snap-on unit 2, the horizontal cantilever 21 is cast on one side of the cast-in-place beam 1 close to the caisson body 3, and the lower hanging cantilever 22 is cast on the lower part of the horizontal cantilever 21 away from the end of the cast-in-place beam 1; thereby, the cavity formed between the cast-in-place beam 1, the horizontal cantilever 21 and the lower hanging cantilever 22 is used to accommodate the upper part of the caisson flange 32, so that the cast-in-place beam 1, the horizontal cantilever 21 and the lower hanging cantilever 22 are fitted with the upper part of the caisson flange 32, thereby increasing the contact area between the cast-in-place beam 1 and the caisson body 3; due to the setting of the horizontal cantilever 21 and the lower hanging cantilever 22, the path length of the joint between the caisson body 3 and the cast-in-place beam 1 is extended, the water seepage path is extended, the possibility of water seepage is reduced, and at the same time, the connection between the caisson body 3 and the cast-in-place beam 1 is made more stable.
[0036] Specifically, the top elevation of the horizontal cantilever 21 is 50 mm lower than the top elevation of the cast-in-place beam 1 to prevent toilet water from overflowing.
[0037] Preferably, if Figure 3As shown in the figure, the embedded reinforcement assembly includes a top reinforcement unit 33 of the caisson bottom slab 31, and the top reinforcement unit 33 of the bottom slab includes a first grid top reinforcement 330 composed of multiple first reinforcing bars 3301. At both ends of each first reinforcing bar 3301, a first anchor rod 3302 perpendicular to it is provided, and the first anchor rod 3302 is vertically anchored into the cast-in-place beam 1.
[0038] Furthermore, the first reinforcing bar 3301 is located inside the upper part of the caisson bottom slab 31, and the first reinforcing bar 3301 and the first anchor rod 3302 perpendicular to both ends of it form a "匚" shape; multiple first reinforcing bars 3301 are woven into a reinforcing bar grid, and the reinforcing bar grid has good support and tensile strength for the cast-in-place beams 1 around the caisson body 3; the first anchor rod 3302 is exposed outside the caisson bottom slab 31 and vertically anchored into the cast-in-place beam 1, making the connection between the caisson body 3 and the cast-in-place beam 1 more stable longitudinally.
[0039] Preferably, as Figure 4 shown in the figure, the embedded reinforcement assembly further includes a bottom reinforcement unit 34 of the caisson bottom slab 31. The bottom reinforcement unit 34 of the bottom slab includes a second grid bottom reinforcement 340 composed of multiple second reinforcing bars 3401. At both ends of each second reinforcing bar 3401, a second anchor rod 3402 extends, and the second anchor rod 3402 is horizontally anchored into the cast-in-place beam 1.

[0041] Preferably, the embedded reinforcement assembly further includes an inner additional reinforcement 35. One end of the inner additional reinforcement 35 is fixedly connected to the second grid bottom reinforcement 340, and the other end of the inner additional reinforcement 35 is bent at 90° and extends into the inner side of the caisson flange 32. After the inner additional reinforcement 35 reaches the top of the caisson flange 32, it is bent 90° outward from the caisson flange 32.
[0042] Furthermore, the inner additional reinforcement 35 is located inside the caisson body 3 to enhance the overall stiffness between the caisson bottom slab 31 and the caisson flange 32.
[0043] Preferably, the embedded reinforcement assembly further includes an outer additional reinforcement 36. One end of the outer additional reinforcement 36 is fixedly connected to the second grid bottom reinforcement 340, and the other end of the outer additional reinforcement 36 is bent at 90° and extends into the outer side of the caisson flange 32; after the outer additional reinforcement 36 reaches the top of the caisson flange 32, it is bent 90° inward from the caisson flange 32 and extends into the hanging lug 22.
[0044] Furthermore, the outer additional reinforcement 36 can enhance the overall stiffness between the caisson body 3 and the lower hanging lug 22 ; since the horizontal lug 21 and the lower hanging lug 22 are cast on the cast-in-place beam 1 , the outer additional reinforcement 36 can further enhance the overall stiffness between the caisson body 3 and the cast-in-place beam 1 .
[0045] It should be noted that the multiple outer additional ribs 36 and the inner additional ribs 35 are evenly spaced along the caisson flanges 32 around the caisson body 3; the binding of the multiple outer additional ribs 36 and the inner additional ribs 35 on the second grid bottom ribs 340 is allowed to be misaligned, and they only need to be bound and fixed to the second grid bottom ribs 340.
[0046] Preferably, the bending parts of the inner additional rib 35 and the outer additional rib 36 are both provided with distribution ribs 37 perpendicular thereto.
[0047] Furthermore, the distribution ribs 37 provided at the bends of the inner additional ribs 35 can connect multiple inner additional ribs 35; the distribution ribs 37 provided at the bends of the outer additional ribs 36 can connect multiple outer additional ribs 36; thereby increasing the overall rigidity of the caisson body 3 and avoiding the occurrence of cracks.

[0049] Furthermore, the water stop strip adopts the water-swelling rubber water stop strip in the prior art, which expands when exposed to water and can play a role of waterproofing and sealing. The first water stop strip 4 and the second water stop strip 5 are provided to prevent water leakage from the top of the caisson body 3.
[0050] When the main body 3 is prefabricated in the factory, the embedded reinforcement assembly is pre-embedded, and the ends of the first anchor rod 3302, the second anchor rod 3402 and the outer additional reinforcement 36 are exposed, which is convenient for fixing at the construction site. During construction, the prefabricated main body 3 is placed in the corresponding position, the cast-in-place beam 1 is supported and the template is erected, and the caisson part is fixed, and then the first water stop strip 4 and the second water stop strip 5 are placed, and finally the template is cast.
[0051] To summarize, the first anchor rod 3302 is exposed outside the caisson bottom plate 31 and vertically anchored into the cast-in-place beam 1, the second anchor rod 3402 is exposed outside the caisson bottom plate 31 and horizontally anchored into the cast-in-place beam 1, and the outer additional reinforcement 36 reaches the top of the caisson flange 32 and bends 90° to the inner side of the caisson flange 32 and then extends into the lower hanging ear 22, so that the longitudinal, transverse and top parts of the caisson body 3 are reinforced to penetrate into the cast-in-place concrete part of the cast-in-place beam 1, so that the caisson body 3 and the cast-in-place beam 1 are more firmly fitted, which is conducive to the horizontal force transmission of the floor during an earthquake. At the same time, the first water stop strip 4 and the second water stop strip 5 and the longer water seepage diffusion path make the device have a better anti-seepage effect.
