Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of construction tools, in particular to a frame lattice beam pressure pouring device. BACKGROUND

[0002] Frame lattice beam is a common supporting form in slope protection engineering. The lattice beam is suitable for the slope with stable slope, gentle slope and mainly green conditions. The lattice beam can be regarded as a reinforced concrete structure acting on the slope surface, and the cast-in-situ concrete construction is generally adopted by using the formwork system. The construction of the lattice beam is affected by the slope operation conditions. The apparent quality of the concrete structure after pouring is the main basis for the quality acceptance of the lattice beam. At present, the lattice beam pouring concrete is usually completed by pouring from top to bottom by using the pump truck from the beam top or pouring opening, and the concrete is freely slid to the beam bottom. Because the joint between the formwork and the ground is not tight, the concrete leakage or formwork explosion easily occurs, and the concrete slump cannot be too high, so the fluidity is affected. After the vibration of the vibrator, the bubbles are difficult to be removed from the formwork due to the inclined slope, so after the pouring and formwork removal, the lattice beam surface often appears honeycomb, pitted surface and exposed reinforcement, which needs to be repaired later, affecting the quality acceptance.

DETAILED DESCRIPTION

[0025] To make the objectives, technical solutions, and advantages of this invention clearer, the technical solutions of this invention will be described in detail below. Obviously, the described embodiments are merely some embodiments of this invention, and not all embodiments. Based on the embodiments of this invention, all other implementation methods obtained by those skilled in the art without creative effort are within the scope of protection of this invention.

[0026] The technical solution of the present invention will now be described in detail with reference to the accompanying drawings.

[0027] like Figure 1 As shown, this invention provides a pressure casting device for a frame lattice beam, including a feeding assembly and a grouting assembly. The feeding assembly is positioned above the grouting assembly and is used to pour concrete into the grouting assembly. The grouting assembly includes a casting pipe 6 and an angle adjustment device located below the casting pipe 6. The length of the casting pipe 6 can be reduced as the height of the poured concrete increases, ensuring that the end of the casting pipe 6 is always below the pouring surface. That is, during the pouring process, the end of the casting pipe is always embedded in the concrete. As the height of the poured concrete increases, the concrete pouring pressure increases, leading to difficulties in material delivery. In this case, the length of the casting pipe can be reduced to decrease the pressure at the pouring port, but the end of the casting pipe must always be embedded in the concrete and positioned below the pouring surface. Preferably, the angle adjustment device can adjust the angle of the casting pipe 6 to keep it parallel to the slope of the lattice beam, ensuring that the casting pipe is parallel to the slope of the lattice beam. This results in a more compact pour with smaller air bubbles, eliminating the need for vibration and thus preventing honeycomb, pitting, and exposed reinforcement on the surface of the lattice beam after pouring, thereby improving the quality of the lattice beam.

[0028] Preferably, the casting pipe 6 includes multiple detachably connected pipe units 8. For example... Figure 2 As shown, the pipe unit 8 has an internally hollow structure. One end of the pipe unit 8 is provided with an external thread 81, and the other end is provided with an internal thread, so that the external thread of one pipe unit 8 and the internal thread of another pipe unit 8 form a threaded connection. Thus, the length of the casting pipe can be increased by adding more pipe units or decreased by reducing the number of pipe units. Preferably, the length of the casting pipe 6 is maintained such that its end is always 50 cm below the casting surface.

[0029] Preferably, pipe unit 8 is made of galvanized copper pipe with a wall thickness of 3mm and a diameter of 90mm, and each pipe unit 8 is 50cm long. The pipe units are connected by threads to ensure that the casting pipe can smoothly extend into the steel reinforcement cage of the lattice beam formwork, while ensuring the sealing between the two connecting pipes.

The moving end of the first telescopic hydraulic cylinder 11 is directed towards the end of the pouring pipe 6 and is fixed to the lower side of another pipe unit 8 by a clamping piece 7. The first telescopic hydraulic cylinder 11 is used to increase or decrease the length of the pouring pipe 6. When pouring starts, the first telescopic hydraulic cylinder is activated to extend, so that the pipe unit at the moving end moves outwardly away from the pipe unit at the fixed end, and a pipe unit with a width is left for installing a new pipe unit. After the new pipe unit is installed by screw connection, the clamping piece 7 is loosened, the moving end of the first telescopic hydraulic cylinder is retracted, and the clamping piece 7 is installed on the newly installed pipe unit. The pipe unit installation step is repeated until the pouring pipe is installed to a position about 30 cm below the lattice beam.

Preferably, the buckle 15 is a circular ring-shaped clamping ring, the lower part of the circular ring-shaped clamping ring is fixedly connected by bolts and nuts. Friction pads are arranged on the inner surfaces of the clamping piece 7 and the buckle 15 to increase the friction between the clamping piece or the buckle and the surface of the pipe unit, and to reduce the damage to the surface of the pipe unit.

[0032] Further preferably, a hydraulic piston device 12 is arranged at the end of the pouring pipe 6, the hydraulic piston device 12 includes a piston rod 121 and a second telescopic hydraulic cylinder 122, wherein one end of the piston rod 121 can extend into the pipe unit 8 at the end, and the other end of the piston rod 121 is connected to the moving end of the second telescopic hydraulic cylinder 122 through a connecting plate 123. The fixed end of the second telescopic hydraulic cylinder 122 is fixed to the lower side of the pipe unit 8 at the end by a buckle 15. The hydraulic piston device is used to push the material when the pouring pipe is disassembled or the concrete pouring is not smooth.

[0043] 5. As the pouring height rises, the concrete pouring pressure increases, and the discharge becomes difficult, so the pipe is removed to reduce the pressure of the pouring port. First, close the switch gate of the discharge port, start the rear hydraulic piston device, empty the concrete in the pipe unit to be removed, retract the piston rod, remove a pipe unit, reconnect the remaining pouring pipe, and continue pouring until the pouring reaches the top of the lattice beam.
