Description

Technical Field

[0001] The invention relates to the technical field of concrete pouring, in particular to an energy-saving concrete demoulding device for building construction. Background Art

[0002] Concrete pouring is a key link in construction. Before pouring, adequate preparations must be made. Check the firmness and sealing of the formwork to ensure that it can withstand the pressure of concrete without deformation or leakage. At the same time, review the position and specifications of the steel bars to ensure that they meet the design requirements. The construction site must also be cleaned to remove stagnant water and debris. During the pouring process, the fluidity and slump of the concrete must be controlled. Use a layered pouring method with each layer of moderate thickness to ensure that the concrete is fully vibrated and compacted. Vibration is a key step. Use tools such as vibrating rods to expel the air inside the concrete to improve the density and strength of the concrete. At the same time, pay attention to the continuity of pouring to avoid cold joints;

[0003] After the concrete components are cast and formed, it is difficult to demold due to the adhesion between the concrete and the mold box after solidification. In the traditional demolding process, in order to make the demolding smoother, the operator needs to knock the mold box with a handheld hammer before demolding. After the concrete and the mold box are loosened, the formed concrete is pushed out of the mold box. Manual demolding requires a lot of manpower. If the knocking step is omitted, on the one hand, forced demolding may cause damage to the concrete components, and on the other hand, it is necessary to assemble a more powerful power drive component to achieve demolding, which results in greater energy consumption and is not conducive to energy saving and reducing production costs.

The sealing ring 45 is frictionally matched with the inner wall of the mold box 41, and a handle 46 is fixedly connected to the side of the blocking plate 44 away from the sealing ring 45.

[0032] The push mechanism 5 includes an arc rod 51, which is fixedly connected to the outer surface of the clamping strip 42. The outer surface of the arc rod 51 is rotatably connected to a rotating ring 52. The outer surface of the rotating ring 52 is fixedly connected to a support rod 53.

By providing the one-way bearing 56, when the rotating rod 8 and the gear 9 are reversed, the inner ring of the one-way bearing 56 will not rotate, and when they are forwardly rotated, the inner ring will rotate, thereby causing the threaded ring 57 to rotate.

By setting the pushing plate 510, when the reciprocating screw 58 moves, the concrete in the inner cavity of the mold box 41 can be pushed. The setting of the sliding block 511 can make the movement of the pushing plate 510 more stable. The side of the gear ring 54 away from the fixed rod 55 is fixedly connected with a first extrusion column 512. The number of the first extrusion columns 512 is several, and the several first extrusion columns 512 are evenly distributed. The first extrusion column 512 is extruded and adapted with the extrusion sleeve 384. The inner ring of the gear ring 54 is fixedly connected with a second extrusion column 513. The second extrusion column The number of 513 is several, and several second extrusion columns 513 are evenly distributed. The pushing mechanism 5 also includes a limiting ring 514, which is fixedly connected to the lower surface of the mold box 41. A rotating block 515 is rotatably connected to the inner cavity of the limiting ring 514. By setting the limiting ring 514, the rotating block 515 can be limited so that the rotating block 515 can generate stable rotation in the inner cavity of the limiting ring 514. A knocking plate 516 is fixedly connected to the end of the rotating block 515, and a wedge block 517 is fixedly connected to the end of the knocking plate 516.

The upper surface of the end portion 16 is fixedly connected with a second spring 518, and the top end of the second spring 518 is fixedly connected to the lower surface of the mold box 41. By providing the second spring 518, when the knocking plate 516 is tilted, the second spring 518 can store elastic potential energy, thereby causing the knocking plate 516 to rebound. By providing the wedge block 517, when the second extrusion column 513 rotates due to the gear ring 54, the wedge block 517 can be squeezed, thereby causing the knocking plate 516 to swing, thereby causing the knocking block 519 to squeeze and knock on the lower surface of the mold box 41, thereby causing the concrete in the inner cavity of the mold box 41 to vibrate, quickly discharge the bubbles in the concrete after pouring, and improve the density and strength of the concrete after pouring. In the process of demoulding,By knocking the lower surface of the mold box 41 with the knocking block 519, the concrete tightly attached to the inner cavity of the mold box 41 can be loosened, making the demoulding process smoother.

[0034] Working principle: When in use, when pouring concrete, the operator connects the motor 7 to the power supply and turns on the switch of the motor 7, and controls the rotating rod 8 and the gear 9 to reverse. When the gear 9 reverses, the pushing mechanism 5 will reverse. The first extrusion column 512 can squeeze the two extrusion sleeves 384 when the gear ring 54 rotates. When the first extrusion column 512 begins to contact the extrusion sleeve 384, the extrusion sleeve 384 is pushed by the first extrusion column 512, and then the extrusion sleeve 384 rotates together with the rotating column 383 and the rotating ring 33. As the rotating ring 33 rotates, due to the pulling force of the first spring 386, the extrusion sleeve 384 and the rotating column 383 are pulled to rotate relative to the rotating ring 33. When the extrusion sleeve 384 rotates a certain angle, it is out of contact with the first extrusion column 512. At this time, the first extrusion column 512 loses its pushing effect on the extrusion sleeve 384 and the rotating ring 33. Under the influence of the gravity of the weight block 312, the extrusion sleeve 384, the rotating ring 33 and the fixed frame 37 drive the side plate 39 and the mold mechanism 4 to reset until the next first extrusion column 512 contacts the extrusion sleeve 384 to repeat the above process. The above structural arrangement can make the mold mechanism 4 shake during the pouring process, so that the poured concrete can be quickly leveled, effectively avoiding the concentration of concrete near the pouring port in the mold box 4, improving the pouring efficiency, and compared with the natural leveling of concrete, the filling in the mold box 4 is more sufficient and compact; while the gear 9 drives the gear ring 54 to rotate, the second extrusion column 513 squeezes the wedge block 517, thereby causing the knocking plate 516 to swing, and causing the knocking block 519 to knock on the lower surface of the mold box 41, thereby causing the concrete in the inner cavity of the mold box 41 to vibrate, making it easier to discharge bubbles in the poured concrete, thereby improving the density and strength of the concrete after the pouring is completed;

[0035] When the concrete needs to be demolded, the operator first controls the motor 7 to reverse, and uses the second extrusion column 513 to squeeze the wedge block 517, so that the knocking plate 516 swings, and then the knocking block 519 knocks on the lower surface of the mold box 41 to produce vibration, so that the concrete and the inner wall of the mold box 41 are loosened, and then the operator controls the motor 7 to rotate forward, so that the gear ring 54 drives the threaded ring 57 to rotate, and then the reciprocating screw 58 moves in the inner cavity of the threaded ring 57, and the push plate 510 moves in the inner cavity of the mold box 41, so that the concrete is squeezed out of the mold box 41, completing the demolding process.
