Description

Technical Field

[0001] This utility model relates to the technical field of anti-flow devices, and in particular to an anti-flow device for concrete pouring. Background Technology

[0002] The quality of the concrete slab forming for sloping roofs has always been a key focus and challenge in sloping roof construction. The main reason is that during the concrete pouring process, the concrete, which has not yet reached its initial set, flows downwards due to its own weight. This results in the concrete at the eaves being too thick and the concrete at the top being too thin. The traditional method is to manually shovel the lower part of the concrete to the upper part after the concrete has initially set, thus ensuring the slab thickness. However, by this time the concrete has already completed its initial set, and the newly laid concrete does not have good adhesion to the lower layer, making it prone to cracking. The construction process is difficult to control, leading to a waste of a lot of manpower and resources, reduced work efficiency, and ultimately poor practicality. Utility Model Content

[0003] Technical problems to be solved

[0004] To solve the above-mentioned technical problems, this utility model provides a concrete pouring anti-flow device that is easy to fix, improves work efficiency, and enhances practicality.

[0005] Technical solution

[0006] To achieve the above objectives, this application provides the following technical solution: a device for preventing spillage during concrete pouring, comprising a base plate, wherein the fixing mechanism includes a first support plate, the first support plate being fixedly installed on the base plate, a groove being formed at the bottom end of the first support plate, a dual-axis motor being fixedly installed on the base plate, and rotating holes being formed at both ends of the groove, the two output ends of the dual-axis motor respectively rotating through the two rotating holes, and a first bevel gear being fixedly installed at both output ends of the dual-axis motor; a second support plate and a third support plate are fixedly installed at both ends of the first support plate, and a first screw and a second screw are rotatably installed on the two second support plates respectively. The rod has a first screw and a second screw, the top ends of which are rotatably connected to two third support plates. A second bevel gear is fixedly installed at the bottom end of both the first and second screws, and the two first bevel gears mesh with the two second bevel gears respectively. A first sliding groove is provided on the first support plate, and a sliding plate is slidably installed within the first sliding groove. A slider is fixedly installed at both ends of the sliding plate, and the two sliders are screwed onto the first and second screws respectively. A rotating groove is provided on the sliding plate, and a support rod is rotatably installed within the rotating groove. A baffle is fixedly installed on the support rod, and a casting groove is provided on the baffle. The locking mechanism is installed on the support rod and is used to lock the support rod.

[0007] By adopting the above technical solution, the dual-axis motor is started. The dual-axis motor drives the first screw and the second screw to rotate through the meshing of two first bevel gears and two second bevel gears. The two sliders screwed to the first screw and the second screw respectively drive the slide plate to rise to a suitable height. After rising to a suitable height, the locking mechanism is released from the limit of the support rod, the baffle is rotated so that the baffle is in contact with the roof slope, and the support rod is fixed by the locking mechanism. Then, cement is poured into the pouring groove of the baffle, thereby avoiding the cement from flowing and causing uneven thickness. This process realizes the easy fixation process, improves work efficiency, and thus enhances practicality.

[0008] Preferably, the locking mechanism includes a turntable, which is fixedly mounted on a support rod. A bolt is screwed onto the turntable, and a circular groove is provided on the slide plate. Multiple slots are provided around the circular groove, and the bolt is engaged with one of the slots.

[0009] By adopting the above technical solution, the bolt is turned to disengage it from the slot, thus releasing the limit on the support rod. The bolt is then tightened to extend into the slot, limiting and fixing the support rod to prevent it from rotating, thereby enhancing its practicality.

[0010] Preferably, a handle is fixedly installed on the baffle.

[0011] By adopting the above technical solution, the baffle can be easily rotated by holding the handle, thereby enhancing ease of use.

[0012] Preferably, protective covers are fixedly installed at both ends of the first support plate.

[0013] By adopting the above technical solution, the protective cover can protect the meshing point of the first bevel gear and the second bevel gear, thereby enhancing safety.

[0014] Preferably, multiple casters are evenly fixedly installed on the bottom end of the base plate.

[0015] By adopting the above technical solution, the device can be transported to the required location, thereby enhancing its practicality.

[0016] Beneficial effects

[0017] Compared with the prior art, this application provides a device for preventing spillage during concrete pouring, which has the following advantages:

[0018] The dual-axis motor is started, and through the meshing of two first bevel gears and two second bevel gears, it drives the first and second screws to rotate. The two sliders screwed onto the first and second screws respectively drive the slide plate to rise to the appropriate height. After rising to the appropriate height, the locking mechanism is released from the limit of the support rod, and the baffle is rotated so that it fits against the roof slope. The support rod is then fixed by the locking mechanism. Cement is then poured into the pouring groove of the baffle, thus avoiding cement flow and uneven thickness. This process facilitates fixation, improves work efficiency, and enhances practicality. Attached Figure Description
