[0002] Upper and lower cantilever wall continuous casting molds are a formwork system specifically designed for cantilever wall construction. They are designed to form wall structures by continuously pouring concrete. Cantilever walls are typically used to support a part of a structure, such as a suspended floor slab or other component. Upper and lower cantilever wall molds are specially designed to meet the needs of this wall form, ensuring that the formwork can stably bear the weight of the concrete and maintain the geometry of the wall during the pouring process.

[0003] Currently, while existing continuous casting molds for upper and lower cantilever walls can assist in casting, they are not convenient for continuous casting. Excessive casting intervals can lead to cold joints at the interface between new and old concrete, affecting structural safety and functionality. Therefore, this paper proposes a continuous casting mold for upper and lower cantilever walls. Utility Model Content

[0005] This utility model is achieved through the following technical solution: a continuous casting mold for upper and lower cantilever walls, comprising four frame columns, with two frame beams slidably connected to the inner wall of each set of frame columns, and a casting mechanism being provided inside the four frame columns. The casting mechanism includes an upper cantilever wall body. The upper surface of the upper cantilever wall body is fixedly connected to the bottom surface of two frame beams. The upper surfaces of the other two frame beams are jointly fixedly connected to a lower cantilever wall body. A keel frame and a keel plate are slidably connected to the inner wall of the lower cantilever wall body. The outer surface of the keel plate is slidably connected to the inner wall of the keel frame. A first bolt is threaded onto the inner wall of the keel frame, and the outer surface of the first bolt is threaded onto the inner wall of the keel plate. Two dovetail blocks are fixedly connected to the bottom surfaces of both the keel frame and the keel plate. The outer surface of the dovetail block is slidably connected to the inner wall of the lower cantilever wall body. The upper surface of the keel frame and the upper surface of the keel plate are in contact with the bottom surface of the upper cantilever wall body. The inner bottom wall of the upper cantilever wall body is provided with a bottom mold hole. A steel insert plate is slidably connected to the inner wall of the upper cantilever wall body. Two limiting frames are fixedly connected to the inner wall of the keel frame. A chute frame is slidably connected to the inner walls of the two limiting frames. A support block and a sealing ring are fixedly connected to the bottom surface of the chute frame. The bottom surface of the support block and the bottom surface of the sealing ring are in contact with the upper surface of the lower cantilever wall body.

[0006] Each of the frame columns has a second bolt threaded to its inner wall, and the ends of each group of second bolts that are close to each other are threaded to the inner wall of the frame beam.

[0014] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this application.

[0015] Please see Figures 1-5 This utility model embodiment provides a continuous casting mold for upper and lower cantilever walls, including four frame columns 1, and two frame beams 2 are slidably connected to the inner wall of each set of frame columns 1. The four frame columns 1 are jointly provided with a casting mechanism 3. The casting mechanism 3 includes an upper cantilever wall body 301. The upper surface of the upper cantilever wall body 301 is fixedly connected to the bottom surface of two frame beams 2. The upper surfaces of the other two frame beams 2 are fixedly connected to the lower cantilever wall body 302. The inner wall of each frame column 1 is threaded with a second bolt 4. The ends of each group of second bolts 4 that are close to each other are threadedly connected to the inner wall of the frame beam 2. During the casting process, the mold will be subjected to the pressure of concrete. The second bolts 4 can effectively resist this pressure and prevent the frame beam 2 from sliding or displacing in the frame column 1, thus ensuring the stability of the mold structure during casting.

[0016] The inner wall of the lower cantilever wall body 302 is slidably connected with a keel frame 303 and a keel plate 304. The outer surface of the keel plate 304 is slidably connected to the inner wall of the keel frame 303. The inner wall of the keel frame 303 is threadedly connected with a first bolt 308. Each set of frame columns 1 is fixedly connected to a fixing frame 5 on one side that is close to each other. The inner wall of each set of fixing frames 5 is slidably connected with a crossbeam 6. The setting of the crossbeam 6 further enhances the overall rigidity of the entire mold. The crossbeam 6 can connect the two sets of frame columns 1 into a more stable whole, distribute the force, and reduce the deformation of the frame columns 1.

[0017] The outer surface of the first bolt 308 is threadedly connected to the inner wall of the keel plate 304. Two dovetail blocks 307 are fixedly connected to the bottom surface of both the keel frame 303 and the bottom surface of the keel plate 304. The outer surface of each dovetail block 307 is slidably connected to the inner wall of the lower cantilever wall body 302. The inner wall of each fixed frame 5 is threadedly connected to a third bolt 7. The bottom end of each third bolt 7 is threadedly connected to the inner wall of the crossbeam 6. The function of the third bolt 7 is to firmly fix the crossbeam 6, which has been adjusted in position, in the fixed frame 5. During the mold operation, the crossbeam 6 needs to maintain a stable position in order to play its role in enhancing rigidity. The preload generated by the threaded connection of the third bolt 7 can effectively prevent the crossbeam 6 from sliding in the fixed frame 5, thus ensuring the stability of the crossbeam 6's support for the frame column 1.

[0018] The upper surfaces of the keel frame 303 and the keel plate 304 are in contact with the bottom surface of the upper cantilever wall body 301. The inner bottom wall of the upper cantilever wall body 301 is provided with a bottom mold hole 306. The inner wall of the upper cantilever wall body 301 is slidably connected with a steel insert plate 305. The inner wall of the keel frame 303 is fixedly connected with two limit frames 310. The bottom surface of each fixed frame 5 is fixedly connected with a reinforcing block 8. The side of each set of reinforcing blocks 8 that is far away from each other is fixedly connected with the side of each set of frame columns 1 that is close to each other. The reinforcing block 8 can significantly improve the strength of the connection between the fixed frame 5 and the frame column 1. When the fixed frame 5 is subjected to the force transmitted by the beam 6, stress concentration is likely to occur at the connection part between it and the frame column 1. The reinforcing block 8 disperses the stress by increasing the force-bearing area of ​​the connection part, and prevents the fixed frame 5 from falling off or being damaged due to excessive force.

[0019] The inner walls of the two limiting frames 310 are slidably connected to a chute frame 309. A support block 311 and a sealing ring 312 are fixedly connected to the bottom surface of the chute frame 309. The bottom surfaces of both the support block 311 and the sealing ring 312 are in contact with the upper surface of the lower cantilever wall body 302. Two side plates 9 are fixedly connected to the sides of the two sets of frame beams 2 that are close to each other. One set of side plates 9 has its side surfaces in contact with the two sides of the upper cantilever wall body 301, and the other set of side plates 9 has its side surfaces in contact with the two sides of the lower cantilever wall body 302. The inner wall of the side plate 9 is slidably connected to the outer surface of the steel insert plate 305. The side plate 9 provides lateral support and positioning for the upper cantilever wall body 301 and the lower cantilever wall body 302, preventing lateral deformation of the upper cantilever wall body 301 and the lower cantilever wall body 302 caused by lateral extrusion of concrete during the pouring process, thus ensuring the lateral dimensional accuracy of the cantilever wall. At the same time, the side plate 9, which is slidably connected to the steel insert plate 305, provides guidance for the movement of the steel insert plate 305, ensuring that the steel insert plate 305 can be accurately inserted into the bottom formwork hole 306, thereby achieving effective sealing and separation of the pouring space.

[0020] When using this utility model: First, the staff transports the device to a suitable location. Then, the keel frame 303 is inserted into the lower cantilever wall body 302. The keel frame 303 drives the limit frame 310 to move. Then, the chute frame 309 is inserted into the two limit frames 310 and the chute frame 309 contacts and abuts against the inner wall of the keel frame 303. Then, the keel plate 304 is inserted into the keel frame 303 and slid along the inner wall of the keel frame 303 to a suitable position. At this time, the bottom surface of the keel plate 304 contacts the upper surface of the lower cantilever wall body 302 and contacts and holds the keel plate 304 against the chute frame 309, thereby limiting the chute frame 309. The keel plate 304 is then fixedly connected to the keel frame 303 by the first bolt 308 to ensure the stability of the keel structure during the pouring process. Next, concrete is poured through the pouring hole at the top of the upper cantilever wall body 301. During pouring, concrete flows out through the bottom formwork hole 306 into the chute frame 309, which guides the concrete downwards. Because the bottom surface of the chute frame 309 is equipped with a support block 311 and a sealing ring 312, concrete leakage is effectively prevented. Simultaneously, the bottom surfaces of the support block 311 and the sealing ring 312 are in close contact with the upper surface of the lower cantilever wall body 302, ensuring the stability of the pouring pressure. Subsequently, the concrete enters through the hole on the lower cantilever wall body 302. During continuous pouring, when the concrete in the lower cantilever wall body 302 is poured, the steel insert plate 30 can be moved. 5. The bottom formwork hole 306 is closed, thereby cutting off the pouring channel between the upper cantilever wall body 301 and the lower cantilever wall body 302. Since the steel insert plate 305 is slidably connected to the side plate 9, it can be accurately inserted into the bottom formwork hole 306, ensuring the effective sealing and separation of the pouring space. When the steel insert plate 305 is pushed in, the thicker end first enters until it moves to the thinner middle position. Then the steel insert plate 305 slides down to cover the bottom formwork hole 306. Then the thicker end on the outside closes the groove of the side plate 9 and the upper cantilever wall body 301. When pouring concrete, the steel insert plate 305 is subjected to the pressure of the concrete and the supporting force of the bottom formwork to form a stable partition structure. Finally, the cantilever wall body 301 can be continuously poured. During the pouring process, the keel frame 303, keel plate 304 and internal chute frame 309 can be disassembled as needed.
