Description

Technical Field

[0001] The invention relates to the technical field of civil engineering, in particular to a concrete joint setting machine. Background Art

[0002] Large-scale infrastructure projects such as canals, reservoirs, highways, and airports inevitably involve the mechanized construction of large, thin concrete linings. The current mainstream domestic construction process for these large, thin concrete joints involves manually cutting the joints with a handheld cutter during the concrete curing period after lining construction. Jointing materials such as closed-cell plastic sheets are then placed in the joints, followed by drainage materials. Alternatively, the lining is carried out in sections, and after the concrete is laid, the formwork is removed, jointing materials are applied to the edges of the concrete sections, and the lining of the next section is continued. Other similar methods have the disadvantages of harsh working environments, slow construction progress, and high construction costs.

[0003] Most of the existing jointing and dividing operations are carried out by manual cutting and dividing during the lining concrete curing stage. Only some projects use mechanized jointing equipment. This type of equipment only realizes the transition from manual to mechanical, is limited to specific scenarios, and cannot be promoted for large-scale use.

[0004] For example, Chinese patent CN219711000U discloses a machine for prefabricating concrete expansion joints during the shaping phase. The machine has a fixed-length truss with a linear reciprocating drive mechanism installed on the truss. Traveling legs are installed at both ends of the truss. The movable end of the linear reciprocating drive mechanism is connected to a slotting machine slidably mounted on the truss. A mainframe is hingedly mounted on the frame of the slotting machine. A vibrating motor is installed inside the mainframe. A soft cutter is installed at the bottom of the mainframe. The internal vibrating motor is connected to a screed plate distributed on both sides of the soft cutter. This patent represents a typical technical solution for constructing expansion joints during the concrete shaping phase. This type of equipment was developed based on the needs of channel construction in water conservancy projects, and therefore only considers joint construction within channels. For channel joint construction, this improves construction efficiency and saves construction costs compared to manual methods. However, it is not universally applicable to scenarios with variable slope ratios, variable slope lengths, large turns, and flat slopes, and has certain deficiencies in reliability and convenience.

[0030] Step 2: First, perform longitudinal joint construction. Adjust the depth of the joint cutting head 42 of the jointing assembly 4 and turn on the inserted vibrator 44. Operate the roller frame 33 to move on the telescopic truss 3. The jointing assembly 4 forms longitudinal joints on the lining surface. Before jointing, manually place the jointing material in the middle of the cutting head.

The telescopic truss 3 is hinged to the turntable 16 to realize the swing of the telescopic truss 3 in the vertical direction, solving the problem that the concrete joint setting machine in the prior art cannot achieve universal technical problems in scenarios with variable slope ratio, variable slope length, large turns, and flat slopes. The present invention can adaptively change the length and angle of the telescopic truss 3 without manual intervention. The two sets of roller frames 33 in the telescopic truss 3 are equipped with the joint setting component 4 to complete the construction of horizontal and vertical expansion joints respectively, speeding up the construction progress and saving construction costs.
