[0023] like Figures 1 to 4 As shown, a schematic diagram of an embodiment of a device for improving the forming quality of walls and columns of the utility model includes a steel bar 1, which can position a template 2 set in four directions, and also includes a plurality of adjustment mechanisms, each of which includes a support rod 3 and a positioning assembly for abutting the inner side of the template 2, each support rod 3 is connected to the steel bar 1 and is arranged vertically to the template 2, and the positioning assembly is slidably connected to the support rod 3 to adjust the distance between the steel bar 1 and the template 2.

[0024] The connection method between the support rod 3 and the steel bar 1 can be clamped, tied or welded in different embodiments. In this embodiment, the support rod 3 and the steel bar 1 are connected by welding technology, and the overall fixation of the device is more secure by spot welding. The operation is simple and convenient, and it can avoid the problems of plastic buckles or concrete pads being loosely fixed and offset, thereby improving the quality of wall and column molding. In this embodiment, the steel bar 1 includes a main bar 11 and stirrups 12, and the support rod 3 is connected to the main bar 11 for reinforcement.

[0025] In this embodiment, each adjustment mechanism includes two positioning components, which are respectively arranged at both ends of the support rod 3. The symmetrical arrangement can simultaneously position the templates 2 arranged on both sides of the support rod 3, thereby improving construction efficiency.

[0026] In this embodiment, each positioning assembly includes a fixing nut 4 and a positioning frame 5 for abutting the inner wall of the template 2. In this embodiment, the positioning frame 5 is U-shaped and the opening faces the template 2. The surfaces of both ends of the support rod 3 are provided with threads and are respectively threadedly connected with the positioning frame 5 to simultaneously abut the templates 2 arranged on both sides of the support rod 3. The fixing nut 4 is threadedly connected with the support rod 3 and is arranged on the side of the positioning frame 5 away from the template 2 to limit the position. In this embodiment, the positioning frame 5 uses a steel bracket. By cooperating with the fixing nut 4 to rotate the thread on the support rod 3, the distance between the steel bar and the template, that is, the thickness of the steel bar protective layer, can be flexibly and accurately adjusted. It can be widely used in construction scenes of walls and columns of different sizes. The adjustment is more accurate through thread rotation, the construction quality is improved, the steel bar 1 is better protected, the service life of the wall and column is increased, and the later maintenance cost is reduced. This design has obvious improvement effects on difficult-to-control areas, such as columns and walls with high floor heights or easy to deviate. The positioning of the steel bar protective layer is more convenient and quick, and the positioning of each section of the wall and column template 2 can be better guaranteed. The U-shaped design of the positioning frame 5 is not only simple in structure and light in device, but also can provide multi-point support for the template 2, so as to achieve simultaneous abutment of adjacent templates 2. Through the abutment force between the positioning frame 5 and the template 2, the misalignment of the template 2 joints is reduced, and the deformation of the template 2 due to uneven force is reduced, thereby avoiding the misalignment of the concrete platform; the positioning frame 5 can also be applied to the position where the template 2 is deformed, and the deformation of the template 2 is reduced by the abutment force, thereby improving the quality of wall and column forming. Some components of the utility model, namely the support rod 3, the fixing nut 4 and the positioning frame 5, can be processed and manufactured using the remaining waste materials on the construction site. The device is simple and the processing cost is low, which saves construction materials and has a positive impact on environmental protection.

[0027] In this embodiment, multiple adjustment mechanisms are arranged in groups of two perpendicular to each other to simultaneously abut against the templates 2 arranged in four directions, and multiple groups of adjustment mechanisms are arranged at intervals along the height direction of the template 2. By placing two adjustment structures in each group crosswise in two directions, it is ensured that after the device is fixed to the templates 2 in four directions, each direction can be uniformly stressed, which can not only support the templates 2 in four directions at the same time, but also better prevent the templates 2 from being deformed and dislocated due to uneven stress, thereby improving construction efficiency and quality.

[0028] In this embodiment, at least one force applying rod 41 is disposed on the outer side of the fixing nut 4 to facilitate quick and convenient adjustment by construction personnel.

[0029] The construction method of the utility model is as follows:

[0030] Multiple groups of adjustment mechanisms are arranged at intervals to simultaneously position the templates 2 in four directions, and each support rod 3 is welded to the steel bar 1 for reinforcement. When the template 2 has local deformation, the positioning frame 5 is arranged at the deformation position and is closely attached to each other to reduce the deformation of the template 2. When multiple templates 2 are spliced, the positioning frame 5 is arranged at the joints of two adjacent templates 2 and abuts against the two adjacent templates 2 at the same time to reduce the splicing misalignment of the adjacent templates 2;

[0031] Rotate the movable positioning frame 5 to fine-tune the distance between the steel bar 1 and the template 2 and limit the position through the fixing nut 4;

[0032] After the multiple groups of adjusting mechanisms are fixed, each group of adjusting mechanisms is connected to the corresponding template 2, and then concrete pouring is carried out.

[0033] The specific working process of this example is as follows:

[0034] Before construction, each adjustment mechanism is preliminarily connected, that is, the support rod 3, the fixing nut 4 and the positioning frame 5 are preliminarily connected;

[0035] After the steel bars 1 are tied, the adjusting mechanisms are arranged in pairs perpendicular to each other. Each group of adjusting mechanisms is evenly spaced along the height direction of the template. The two adjusting mechanisms in each group are arranged perpendicular to each other to ensure accurate positioning of the protective layer from all directions. When the position of the adjusting mechanism is fixed, ensure that the length of each adjusting mechanism end extending out of the outermost steel bar 1 is basically the same;

[0036] The support rod 3 is fixedly connected to the steel bar 1. In this embodiment, the fixing effect is improved by spot welding with the steel bar 1. The overall levelness of the welding process can be monitored by a level ruler. After the spot welding is completed, the distance from the inner side of the template 2 to the outer side of the steel bar 1 is finely adjusted by rotating the positioning frame 5 and the fixing nut 4, that is, the thickness of the protective layer is further accurately positioned;

[0037] Then, multiple templates 2 are molded together. During the mold-closing process, if there are joints between the upper and lower ranges of the template 2 or the template 2 is deformed due to long-term storage, moisture, etc., the joints or deformed areas can be set at the positioning frame 5. In this embodiment, it should be set in the opening of the U-shaped positioning frame 5, so that the positioning frame 5 can simultaneously support the upper and lower templates 2 or the deformed areas, and the positioning frame 5 is tightly fitted with the template 2 to generate an interaction force, thereby reducing the dislocation of the template 2, adjusting and improving the deformation of the template 2, and reducing the risk of misalignment.

[0038] The utility model ensures that the device structure is stable and not prone to deviation through the fixation method of the support rod 3 and the steel bar 1 by spot welding; the support rod 3 is threadedly connected to the positioning component to flexibly adjust the thickness of the protective layer, so as to better carry out the protection construction of the steel bar 1, so that each section of the template 2 can be accurately positioned, thereby improving the construction quality and the service life of the wall and column, and reducing the later maintenance cost; by cross-setting a plurality of adjustment mechanisms in groups of two, the device is evenly stressed when being fixed to the templates 2 in four directions, and the deformation and dislocation of the template 2 caused by uneven stress; the U-shaped positioning frame 5 can effectively support the joints of the template 2, reduce the dislocation of the joints and deformation of the template 2 caused by mold closing and other reasons, and avoid the quality risks such as misalignment caused by unstable concrete stress; some components of the device of the utility model can be processed with waste materials on the construction site, so as to make full use of construction resources, avoid waste of raw materials and have a positive impact on environmental protection.

[0039] The above is a detailed description of the embodiments of the utility model, but the contents are only preferred embodiments of the utility model and cannot be considered to limit the scope of implementation of the utility model. All equivalent changes and improvements made within the scope of application of the utility model should still fall within the scope of the patent coverage of the utility model.
