The utility model can adjust the shape and size of the building formwork, and improve the efficiency of civil construction.

[0004] The above patent document has the following shortcomings: although the shape of the assembly can be adjusted by adjusting the angle between the left and right plates, the assembly by plugging may result in low firmness during concrete pouring, which may easily cause the formwork to be stretched, affecting the pouring of concrete and causing a decrease in construction progress;

[0005] For this purpose we have designed an adjustable concrete formwork. Utility Model Content

[0006] The technical problem solved by the utility model is to provide an adjustable concrete formwork which is highly practical, can be easily operated and has a relatively simple structure, thereby solving the problem in the above-mentioned background technology that the assembly by plugging may have low firmness during concrete pouring.

[0007] To achieve the above objectives, the utility model is implemented through the following technical solutions: an adjustable concrete formwork, comprising a first formwork, a fixed block is fixedly connected to one side of the first formwork, a rectangular groove is opened at the center of the surface of the fixed block, a stopper is fixedly connected to the inner wall of the rectangular groove, a cover plate is fixedly connected to the surface of the fixed block by bolts, a threaded rod is threadedly connected to the surface of the cover plate, a movable plate is threadedly connected to the surface of the threaded rod, one end of the threaded rod is rotatably connected to the inner wall of the rectangular groove through a bearing, raised blocks are provided at both ends of the movable plate, a guide rod is rotatably connected to the surface of the raised block, a U-shaped block is rotatably connected to one end of the guide rod, a fixed column is fixedly connected to the surface of the U-shaped block, an elliptical block is fixedly connected to the surface of the fixed column, and the center of one end of the elliptical block coincides with the center of the fixed column.

[0008] Optionally, sliding grooves are provided on both sides of the fixed block, and the interior of the sliding grooves is movably connected with fixed columns. The sliding grooves can make the fixed columns move inside, thereby driving the connecting plates to rotate and slide inside the sliding grooves.

[0009] Optionally, both ends of the fixed column pass through the fixed block and are fixedly connected with a connecting plate, one end of the connecting plate is provided with an open groove, and the open groove can hook the cylindrical lifting device to ensure its firmness and prevent it from being stretched apart during concrete pouring.

[0010] Optionally, one side of the first template is slidably connected to the second template, one side of the second template is fixedly connected to a cylinder, one end of the cylinder is fixedly connected to an anti-slip block, and the anti-slip block can reduce the connection plate from sliding off the surface of the cylinder.

[0011] Optionally, a protruding block is fixedly connected to the bottom of the first template, and a mounting hole is provided on the surface of the protruding block, so that the mounting hole is convenient for installing the device at the construction site.

[0012] Optionally, the opening groove of one section of the connecting plate is slightly larger than the diameter of the cylinder and smaller than the diameter of the anti-slip block. The opening groove is slightly larger than the cylinder to facilitate the opening groove of the connecting plate to slide into the surface of the cylinder, and the opening of the opening groove is larger than the diameter of the cylinder.

[0013] The utility model provides an adjustable concrete formwork, which has the following beneficial effects:

[0014] The adjustable concrete template is provided with a first template, a fixed block, a threaded rod, a movable plate, a guide rod, a U-shaped block, a fixed column, an elliptical block, a connecting plate, a second template and a cylinder. When the device is used, the second template is plugged into the first template so that the shape of the device is rectangular. The threaded rod is rotated to drive the movable plate to move and drive one end of the guide rod to move toward the cover plate, while the other end of the guide rod drives the two U-shaped blocks to move toward the movable plate, thereby driving the two fixed columns to move in the opposite direction and drive one end of the opening groove of the connecting plate to move toward the cylinder. With the rotation, after the opening groove of the connecting plate slides into the surface of the cylinder, the elliptical block on the surface of the fixed column is still rotating and then abuts against the inner wall of the rectangular groove at the center of the fixed block, driving the other end of the connecting plate backward so that the opening groove of the connecting plate pulls the cylinder and stops rotating after the elliptical plate abuts against the stopper. At this time, the opening groove of the connecting plate is hooked on the surface of the cylinder, thereby increasing the firmness of the first template after being plugged in with the second template, reducing the concrete from spreading the first template and the second template during pouring, and improving the progress of concrete pouring construction.

As the rotation progresses, after the opening groove of the connecting plate 11 slides into the surface of the cylinder 13, the elliptical block 10 on the surface of the fixed column 9 is still rotating, and then abuts against the inner wall of the rectangular groove at the center of the fixed block 2, and the other end of the connecting plate 11 is driven backward, so that the opening groove of the connecting plate 11 pulls the cylinder 13, and the rotation stops after the elliptical plate abuts against the stopper. At this time, the opening groove of the connecting plate 11 is hooked on the surface of the cylinder 13, which increases the firmness of the first template 1 and the second template 12 after being plugged in, reduces the concrete from propping up the first template 1 and the second template 12 during pouring, and improves the progress of concrete pouring construction;
