Technical Field
[0001] The utility model belongs to the technical field of large-area concrete pouring, and particularly relates to a partition joint positioning device for ground engineering. Background Art
[0002] Because the amount and area of concrete poured at one time are usually large, as well as the uneven shrinkage, expansion and internal temperature stress generated by concrete during the hardening process, traditional ground construction technology is very likely to cause quality problems such as concrete cracks, hollowing of cement floors, damage to the edges and corners of divided joints, and poor overall flatness.
[0003] Currently, concrete floors are generally undecorated for economic, environmental, and social reasons. Therefore, high standards are imposed on the smoothness, appearance, and joints of large-scale concrete floors. Especially for undecorated floors, joints become a decorative element. Traditional floor joint construction involves directly cutting the concrete or pre-cutting wooden strips. This often requires significant labor and time to cut the joints, remove debris from the joints, remove pre-cut wooden strips, and trim rough edges. This makes it difficult to ensure a neat and aesthetically pleasing joint, resulting in less than ideal construction efficiency and results. Furthermore, the process is lengthy, labor-intensive, and labor-intensive, resulting in significant daily labor costs. Utility Model Content

[0017] The utility model provides an embodiment:
[0018] like Figure 1 、 Figure 2 As shown, a partition joint positioning device for ground engineering includes a partition plate, a clamping claw 2, a door-shaped support 3 and a threaded positioning rod 4; the partition plate includes a first partition plate 101 and a second partition plate 102 arranged opposite to each other, a partition joint is formed between the two partition plates, and a gasket matching the width thereof is plugged in the partition joint, a plurality of clamping claws 2 are arranged at intervals along the length direction of the partition plate, and the two clamping ends of the clamping claws 2 are respectively clamped at the outer ends of the two partition plates; the door-shaped support 3 is arranged across the partition plate, and the horizontal end of the door-shaped support 3 is threadedly connected to the threaded positioning rod 4, the bottom end of the threaded positioning rod 4 is rotatably connected to the upper end of the clamping claw 2, and the threaded positioning rod 4 has a scale line indicating the elevation.
[0019] In this embodiment, the outer ends of the first and second partitions 101, 102 are provided with a plurality of anchors 5 for gripping concrete at intervals along the length direction. Plug slots are provided on the first and second partitions 101, 102 at positions corresponding to the clamping ends of the clamping claws 2.
[0020] The threaded positioning rod 4 and the clamping claw 2 are rotatably connected through the bearing 6, wherein a bearing seat is provided at the upper end of the clamping claw 2, the outer ring of the bearing 6 is fixed on the bearing seat, and the inner ring of the bearing 6 is fixedly connected to the threaded positioning rod 4. Rotating the threaded positioning rod 4 can drive the clamping claw 2 to change in height, thereby driving the partition plate to change in height.
[0021] During the ground pouring phase of the ground engineering project, custom aluminum alloy grid panels were used to cast the floor in sections. This method first divided the floor into several 4m x 6m units, with custom aluminum alloy grid panels used to separate the units at the joints. C30 fine stone concrete was then used to secure and seal the grid panels. The grid bar elevation was controlled by construction workers using an infrared leveler. The grid panels served both as the expansion and contraction grids for the floor and as a control point for the surface elevation. After the grid panels were laid, a series of operations consistent with traditional methods were carried out, including grouting, placement of steel mesh, concrete pouring, and curing.
[0022] The use of custom aluminum alloy grid panels for floor construction eliminated traditional grid methods, effectively simplifying the process, shortening the construction period, and eliminating common quality issues such as sanding, cracking, and hollowing in the surface layer, reducing the need for rework and maintenance due to quality issues. Furthermore, the concrete floor's grid joints are neat and beautiful, making it suitable for use as formal floors in garages, supermarkets, and factories without the need for renovation or treatment.
[0023] In this embodiment, basic components are combined to form a partition joint positioning device according to the design drawings, and the elevation control system (scale, door-type support, threaded positioning rod, clamping claw) is used to accurately position the elevation. The threaded positioning rod is then used with anchor nails to effectively grip the concrete. Double aluminum alloy partitions form partition joints, and then large-area concrete overall floor construction is carried out.
[0024] The above description is merely a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any changes or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included in the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
