Description

Technical Field

[0001] This utility model relates to the technical field of construction machinery, specifically to a vibratory compaction device for large-area concrete construction. Background Technology

[0002] Concrete vibration is a crucial step in concrete construction. Vibration compacts the concrete, removes air bubbles, and ensures structural strength and durability. The purpose of concrete vibration is to eliminate air bubbles, remove voids in the concrete, and prevent honeycombing and pitting. It also increases density, allowing aggregates and mortar to fully bond, thus enhancing compressive strength. Furthermore, it improves fluidity, helping the concrete fill corners and gaps between reinforcing bars, reducing water permeability, and resulting in a denser structure with improved impermeability.

[0003] A concrete vibratory level is a type of vibration device. It is a specialized tool used for vibrating, scraping, and leveling large concrete surfaces (such as floors, slabs, roads, warehouse floors, etc.).

[0004] Currently, after concrete is vibrated using a vibratory ruler, a thin film needs to be promptly applied to the concrete surface to prevent excessive moisture evaporation and plastic shrinkage cracks. To accelerate construction, existing technology proposes setting an adjustment frame on the vibratory ruler and then installing a curing film cylinder, allowing the vibratory ruler to simultaneously perform the film covering process. Referring to Chinese Patent Publication No. CN111350363A, a concrete vibratory leveling and film covering device is disclosed. While this achieves simultaneous leveling and film covering, only one curing film cylinder can be installed on the adjustment frame at a time. This means that if the vibratory ruler is long, only a longer curing film cylinder can be installed on the adjustment frame to meet the requirement of simultaneous film covering. Furthermore, the lack of a central support point makes the longer curing film cylinder prone to bending, affecting its rotation and causing inconvenience during transport and installation. Utility Model Content

[0005] To address the aforementioned problem of the excessively long curing film cylinders installed on existing vibratory compaction devices, this invention proposes a vibratory compaction device for large-area concrete construction. The device includes a ruler plate on which a vibration mechanism is mounted, a control handle connected to the vibration mechanism, and a film-covering frame connected to the ruler plate. Rotating rollers are rotatably connected to both ends of the film-covering frame. A connecting member is detachably connected to the middle of the film-covering frame, and two rotating rollers are rotatably connected to the connecting member. The two rotating rollers on the connecting member correspond to the two rotating rollers at each end of the film-covering frame, and a film-covering cylinder is rotatably mounted between the corresponding two rotating rollers.

[0006] A further feature of this invention is that the connector includes a U-shaped opening, the U-shaped opening is fastened to the film-coating frame, a set screw is threaded to the top of the U-shaped opening, the set screw is tightened against the film-coating frame, a mounting plate is connected to the bottom of the U-shaped opening, and two rotating rollers are rotatably connected to the mounting plate.

[0007] A further feature of this invention is that a leveling mechanism is installed on the back of the ruler plate for leveling concrete.

[0008] A further feature of this invention is that the leveling mechanism includes a connecting plate, the bottom edge of the connecting plate is set at the same height as the bottom edge of the ruler plate, and a plurality of leveling teeth are installed at equal intervals on the bottom edge of the connecting plate.

[0009] A further feature of this invention is that an adjustment groove is provided on the back plate of the ruler plate corresponding to the connecting plate, and the connecting plate is connected to the adjustment groove by bolts.

[0010] The beneficial effects of this utility model are as follows:

[0011] 1. By installing connectors on the laminating frame, the laminating frame can be divided into two parts for installing laminating tubes, thereby enabling the installation of two short laminating tubes on the laminating frame to meet the laminating length. At the same time, the two short laminating tubes can avoid the influence of the rotation due to the laminating tube being too long, and the short laminating tubes are easier to transport and install.

[0012] 2. By installing a leveling mechanism on the ruler, the un-vibrated concrete can be leveled. During the vibration process, the operator needs to wade through the concrete, which can cause pits and unevenness. Direct vibration can easily result in unevenness. The leveling mechanism can further smooth the concrete and improve the vibration effect. Attached Figure Description

[0019] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0020] This utility model proposes a vibratory compaction device for large-area concrete construction, including a ruler plate 1, which includes a base plate and a back plate, the base plate and the back plate being vertically arranged. A vibration mechanism 2 is installed on the ruler plate 1, and the vibration mechanism 2 in this application adopts an electric motor-driven eccentric block structure. The vibration mechanism 2 is connected to the ruler plate 1 by bolts.

[0021] A control handle 3 is installed on the vibration mechanism 2 to control the vibration process. A film covering frame 4 is also connected to the ruler plate 1 by two support plates. The two support plates are welded to the bottom plate of the ruler plate 1 and are symmetrically arranged about the vibration mechanism 2. The film covering frame 4 includes a crossbeam, which is welded to the two support plates. Support rods are welded to both ends of the crossbeam. The support rods are arranged perpendicular to the crossbeam and are rotatably connected to the support rods for installing the film covering cylinder 7.

[0022] A connector 6 is detachably connected to the middle position of the laminating frame 4. Two rotating rollers 5 are also rotatably connected to the connector 6. The two rotating rollers 5 are symmetrically arranged about the connector 6, and the two rotating rollers 5 are respectively arranged corresponding to the two rotating rollers 5 on the laminating frame 4. That is, a laminating cylinder 7 is rotatably installed between the corresponding two rotating rollers 5. The two ends of the laminating cylinder 7 are respectively fixedly connected to the two rotating rollers 5, thereby achieving the purpose of rotation relative to the laminating frame 4.

[0023] The connector 6 includes a U-shaped opening 61, which is adapted to the crossbeam of the laminating frame 4. The U-shaped opening 61 is fastened to the crossbeam of the laminating frame 4. A threaded hole 611 is provided at the top of the U-shaped opening 61, and a set screw is threaded into the threaded hole 611. One end of the set screw, extending into the U-shaped opening 61, abuts against the crossbeam of the laminating frame 4, thereby fixing the U-shaped opening 61 to the crossbeam of the laminating frame 4. An integral mounting plate 62 is provided at the bottom end of the U-shaped opening 61. Two rotating rollers 5 are rotatably connected to the mounting plate 62 and are symmetrically arranged about the mounting plate 62.

[0024] A leveling mechanism 8 is installed on the back of the ruler plate 1 for leveling concrete. The leveling mechanism 8 includes a connecting plate 81, the length of which is the same as that of the ruler plate 1. The connecting plate 81 is bolted to the back plate. The bottom edge of the connecting plate 81 is at the same height as the bottom plate of the ruler plate 1. Several grating teeth 82 are welded to the bottom edge of the connecting plate 81 and are arranged at equal intervals.

[0025] Four adjustment slots 11 are provided on the back plate of the ruler plate 1. The four adjustment slots 11 are arranged in pairs on both sides of the vibration mechanism 2. The adjustment slots 11 are vertically arranged. The bolts connecting the connecting plate 81 pass through the adjustment slots 11 and are then threaded onto nuts. Tightening the nuts installs the connecting plate 81 onto the back plate. Loosening the nuts allows the height of the connecting plate 81 to be adjusted up and down along the direction of the adjustment slots 11, thereby adjusting the depth of the pry bar 82 inserted into the concrete.

[0026] In summary, by installing a connector 6 on the laminating frame 4, this utility model can divide the laminating frame 4 into two parts for installing laminating cylinders 7, thereby enabling the installation of two short laminating cylinders 7 on the laminating frame 4 to meet the laminating length requirement. At the same time, the two short laminating cylinders 7 can avoid affecting their rotation due to the laminating cylinders 7 being too long, and the short laminating cylinders 7 are easier to transport and install.

[0027] By installing a leveling mechanism 8 on the ruler plate 1, the unvibrated concrete can be leveled. During the vibration process, the operator needs to walk in the concrete, which can cause pits and unevenness. Direct vibration can easily result in unevenness. The leveling mechanism 8 can further make the concrete smoother and improve the vibration effect.
