Abstract
Description
A double-T plate demolding device Technical Field
[0001] This utility model belongs to the field of building technology, and specifically relates to a double-T board demolding device. Background Technology
[0002] Double-T slabs possess excellent structural mechanical properties and are a relatively economical load-bearing component suitable for large spans and large coverage areas. A double-T slab is a concrete component consisting of a wide panel and two narrow, high ribs. The panel serves as both a transverse load-bearing structure and the compression zone for the longitudinal load-bearing ribs.
[0003] Double-T slabs are a common type of precast concrete component, widely used in large-span buildings such as industrial plants, warehouses, and parking lots. The production process involves pouring concrete into a special mold for double-T slabs with a pre-installed reinforcing cage. After the concrete reaches a certain strength, the mold is removed, or the formed double-T slab is taken out of the mold. Traditional demolding methods use a lifting method, employing four or six steel wires or chains to directly lift the component from its lifting points. Due to the large suction force during demolding and the thinness of the slab, this method easily causes stress imbalance, leading to quality problems such as chipping, deformation, and cracking. Repairing these components later requires significant manpower and resources, making it very uneconomical. Furthermore, a typical double-T slab weighs 20-30 tons, and during demolding, there is still a 10-20 ton force adhering to the mold. Currently, there are no high-tensile-force demolding devices, and the safety and stability of the demolding process cannot be guaranteed.
[0004] Therefore, there is an urgent need to design a double-T plate demolding device. Summary of the Invention

[0025] Example
[0026] As shown in Figures 1 to 3, a double-T plate demolding device includes a demolding gantry 200 mounted at opposite ends of a double-T plate 100 to be demolded, a demolding mechanism 300 mounted on the demolding gantry 200, and a hydraulic station 400 located to the side of the demolding gantry 200. The demolding mechanism 300 is mechanically connected to the hydraulic station 400, and the hydraulic station 400 controls the demolding mechanism 300 to perform demolding (pulling out) operations. Demolding connection points 110 are respectively provided on the top surface of the double-T plate 100 near its opposite ends. The output end of the demolding mechanism 300 is connected to the demolding connection points 110. Driven by the hydraulic station 400, the demolding mechanism 300 pulls the double-T plate 100 to be demolded out of the double-T plate special production mold 500.
[0027] It is worth mentioning that the demolding gantry 200 can be selectively added according to the actual length of the double T-plate 100 to be demolded. That is, not only are they provided at the opposite ends of the double T-plate 100 to be demolded, but also several demolding gantry 200 can be evenly distributed along the length of the double T-plate 100 to form a uniform and stable pulling force on the double T-plate 100 to be demolded, ensuring the smooth and stable demolding process of the double T-plate 100 to be demolded, and at the same time, preventing quality problems such as cracking and chipping caused by deformation due to insufficient force.
[0028] In some preferred embodiments, the demolding gantry 200 includes a mounting bracket 210, a reinforcing rib 220, and a mounting beam 230. The mounting bracket 210 is mounted on the side of the double-T plate special production mold 500. The mounting beam 230 is mounted horizontally on the mounting bracket 210 on both sides. One end of the reinforcing rib 220 is connected to the mounting bracket 210, and the other end is connected to the mounting beam 230. The mounting bracket 210, the reinforcing rib 220, and the mounting beam 230 form a triangular stable structure.
[0029] In some preferred embodiments, the demolding mechanism 300 includes jacks 310, a traction ring 320, and a connecting wire rope 330. Two jacks 310 are symmetrically arranged on the mounting beam 230, with the output ends of the jacks 310 pointing vertically downwards. The traction ring 320 is mounted on the output end of the jack 310. One end of the connecting wire rope 330 is connected to the traction ring 320, and the other end is connected to the demolding connection point 110. Notably, 80t jacks 310 are selected.
[0030] In some preferred embodiments, the hydraulic station 400 includes a hydraulic pump, an electric motor, an oil tank, a hydraulic valve assembly, an output pipeline, an inlet connection pipeline, a pipeline, and a control system. The output end of the electric motor is connected to the hydraulic pump, and the electric motor drives the hydraulic pump to operate, so that the hydraulic pump converts mechanical energy into hydraulic energy. The oil tank is used to store hydraulic oil, and the oil tank is connected to the hydraulic pump through the inlet connection pipeline. The output end of the hydraulic pump is connected to the hydraulic valve assembly through a pipeline, and the hydraulic valve assembly regulates the output hydraulic oil. The hydraulic valve assembly is connected to the jack through the output pipeline. The jack 310 is connected as an actuator, converting hydraulic energy into mechanical energy to perform demolding of the double T-plate 100. The motor and hydraulic valve group are electrically connected to and controlled by the control system. The control system controls the rotation of the motor, which in turn drives the hydraulic pump to pump oil, causing the jack 310 to extend and retract. The hydraulic station 400, through the coordinated work of core components such as pumps, valves, and oil tanks, achieves efficient conversion from hydraulic energy to mechanical energy, thereby completing the demolding operation of the double T-plate 100.
[0031] In some preferred embodiments, the double-T plate 100 to be demolded includes a panel 120 and ribs 130. Two ribs 130 are vertically arranged symmetrically on the lower surface of the panel 120. Demolding connection points 110 are located on the upper surface of the panel 120, and there may be more than one demolding connection point 110. Notably, each demolding connection point 110 can be a connecting hook or ring. The demolding connection points 110 are fixedly installed on the upper surface of the double-T plate 100 to be demolded and can transmit the pulling force during demolding to the double-T plate 100.
[0032] In some preferred embodiments, the double-T board production mold 500 is fixedly installed on the ground to ensure that the demolding mechanism 300 will not pull up the double-T board production mold 500 together with the double-T board 100 during demolding. The double-T board production mold 500 includes a bearing base 510, supporting ribs 520, and a casting platform 530. The casting platform 530 is fixedly installed on the bearing base 510 through the supporting ribs 520. A double-T-shaped casting cavity is formed on the casting platform 530. The double-T board 100 to be demolded is formed on the double-T-shaped casting cavity. The cast double-T board 100 has a large adsorption force on the double-T board production mold 500. The demolding mechanism 300 can form a uniform and stable pulling force on the double-T board 100 to be demolded, so as to disconnect the double-T board 100 from the double-T board production mold 500 and complete the separation.
[0033] In summary, this utility model provides a double-T plate demolding device that can generate a uniform and stable pulling force on the double-T plate to be demolded. Driven by a hydraulic station, the double-T plate to be demolded is disconnected from the double-T plate special production mold, thus completing the separation.
