DETAILED DESCRIPTION

[0026] The silo slipform construction is a general term for the construction method of the cast-in-place concrete structure formed by the slipform jack driving the formwork 18 to slide along the concrete surface. The slipform construction system mainly consists of a lifting system, a formwork system, an operating platform system, a hydraulic lifting system, a precision control system, a water and electricity supporting system, etc. The formwork system in the above system mainly consists of a lifting frame 16, a ring 17, a formwork 18, and an operating platform 19. The lifting frame 16 is provided with multiple lifting frames 16, which are installed at equal intervals according to the construction position, and the whole is annular. The ring 17 is installed on the lifting frame 16 and is arranged along the inner and outer walls of the silo. Then, the inner and outer formworks 18 are installed on the two rings 17. Then, the inner and outer operating platforms 19 are laid on the inner and outer formworks 18, and a tripod structure arrangement is usually adopted.

[0027] The lifting frame 16 described above consists of a crossbeam 1, a stand 2, and a cantilever beam frame 3. The stand 2 is provided with two vertical stands 2 on both sides of the crossbeam 1, and the cantilever beam frame 3 is provided with multiple cantilever beam frames 3 symmetrically distributed on the two stands 2.

[0028] Example 1

[0029] The improved structure of the silo slipform construction support platform, as shown in Figures 1-6 , mainly improves the structure of the lifting frame 16. The stand 2 described above is composed of a cylinder 4 and a column 5. The cylinder 4 is welded or connected by bolts with the crossbeam 1. The upper section of the column 5 is located in the cylinder 4 and can slide in the cylinder 4. A first spring 20 is arranged in the cylinder 4. The two ends of the first spring 20 are respectively connected with the bottom of the cylinder 4 and the end of the column 5. Pin holes are provided on the cylinder 4 and the column 5 to fix the positional relationship between the cylinder 4 and the column 5. Two groups of cantilever beam frames 3 are provided and are horizontally slidably installed on the two columns 5.

[0030] Specifically, the cantilever beam frame 3 consists of a T-shaped cross frame 6, a connecting frame 7, and an adjusting mechanism. The T-shaped cross frame 6 is provided with two T-shaped cross frames 6, which are horizontally slidably installed on the column 5. The connecting frame 7 is connected to one end of the two cross frames 6 (as Figure 2The adjusting mechanism includes a threaded sleeve 8 and a screw rod 9; the threaded sleeve 8 is transversely rotatably connected to the connecting frame 7 through a bearing, one end of the screw rod 9 is fixedly connected to the column body 5, the threaded sleeve 8 is threadedly matched with the screw rod 9, a second spring 10 is sleeved on the screw rod 9, and the two ends of the second spring 10 are respectively connected with the screw rod 9 and the threaded sleeve 8 (as shown in the figure). Figure 1 Finally, a sensor 11 is arranged on the cross frame 6, the sensor 11 is specifically a microwave humidity sensor, the sensor 11, the control sliding formwork jack in the hydraulic lifting system and the alarm arranged on the operation platform 19 are all interlocked with the PLC controller.

[0031] The working process and principle of the utility model are as follows:

[0032] Before the lifting frame 16 is installed, a worker adjusts the height of the lifting frame 16 and the distance between the two groups of outrigger beam frames 3 according to actual construction requirements. Specifically, the cross beam 1 is pulled to drive the column body 5 to slide in the column cylinder 4, and after being adjusted to a suitable position, a positioning pin or a bolt is inserted into the pin hole to fix the adjusted position. Then the threaded sleeve 8 is rotated to drive the cross frame 6 to slide in the column body 5 to adjust the distance between the cross frames 6 arranged on the two column bodies 5, and the adjusted position can be fixed by a jackscrew or a latch (as shown in the figure); the sensor 11 arranged on the cross frame 6 moves correspondingly. After the adjustment is completed, the lifting frame 16 is installed, and the coaming 17 and the formwork 18 are installed according to the adjusted height and distance.

[0033] During construction, the concrete is poured between the inner and outer formworks 18, the setting condition of the concrete is detected by the sensor 11, when the setting strength suitable for sliding formwork is reached, the sensor 11 sends a signal to the PLC controller, the sliding formwork jack is started by the PLC controller, the support table is driven to slide upwards along the concrete, and the alarm is controlled to be turned on synchronously to remind the worker.

[0034] Embodiment 2

[0035] If the height of the lifting frame 16 and the distance between the two groups of outrigger beam frames 3 need to be adjusted synchronously to save construction time, the synchronous adjusting mechanism is used to realize the function. Specifically, threaded seats 12 are connected to the two ends of the cross beam 1 through screws, positioning seats 13 are connected to the two column bodies 5 through screws, an adjusting screw rod 14 provided with a gear 15 is rotatably connected to the positioning seats 13 through a bearing, the threaded section of the adjusting screw rod 14 is threadedly matched with the threaded seats 12, and finally, teeth are arranged on the cross frame 6, and the gear 15 is meshed with the teeth.

[0036] The working process and principle of the utility model are as follows:

[0037] When the threaded sleeve 8 is rotated, the cross frame 6 is driven to slide in the column 5 by the threaded cooperation between the threaded sleeve 8 and the threaded rod 9, the adjusting screw 14 is driven to rotate by the gear 15 and the gear teeth, and then the column 5 is driven to slide in the column cylinder 4. The synchronous adjusting mechanism has limitations, and is used when the height of the lifting frame 16 needs to be increased and the distance between the cross frames 6 needs to be reduced, or the height of the lifting frame 16 needs to be reduced and the distance between the cross frames 6 needs to be increased.
