[0002] With the rapid development of the society, high-rise residential buildings or industrial plants in cities are mainly buildings with reinforced concrete shear walls and frame columns as the main structure. The problems of mold offset at the root of the wall column and deviation of the thickness of the reinforcement protection layer are common quality defects of frame structures. They have a great influence on the internal stress state of the frame structure and cause the deviation of the building's open bay depth, which affects the later decoration and space function use. How to effectively avoid the occurrence of wall column offset and reinforcement protection layer thickness deviation is extremely critical.

[0003] Traditional wall column positioning is achieved by welding positioning reinforcement at the vertical reinforcement root of the wall column or using the obsolete method of drilling holes in the concrete structure plate to nail positioning reinforcement. Such methods have the following shortcomings in the construction process: first, the positioning reinforcement is welded and fixed with the vertical reinforcement of the wall column, which can easily damage the vertical reinforcement of the wall column and cause the problem of unstable fixation. Second, the construction is complicated, time-consuming and labor-intensive. Since welding or drilling is a one-time alignment with the wall column edge line and cannot be adjusted after forming, workers need high operation technical level. Therefore, there is an urgent need for a quick and adjustable wall column positioner. SUMMARY

[0024] The technical scheme in the embodiments of the utility model will be clearly and completely described below in combination with the drawings in the embodiments of the utility model, obviously, the described embodiments are only some embodiments of the utility model, not all the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor belong to the protection scope of the utility model.

[0025] As Figure 1As shown in the embodiment 1, the adjustable positioner for the root of the reinforced concrete wall column comprises a positioning rod for being arranged on the reinforcement frame, a sleeve 1 is fixedly connected to the positioning rod, and a positioning column 2 corresponding to the wall column positioning line is connected to the sleeve 1. The positioning column 2 is arranged on the reinforcement frame in cooperation with the positioning rod of the sleeve 1, at this time, the outermost surface of the positioning column 2 is located in the same plane as the wall column positioning line, thereby forming the positioning of the wall column formwork, avoiding the damage to the wall column reinforcement frame caused by welding, and the problem of mispositioning of the prefabricated floor, the structure is simple, the operation is convenient, and the device does not need to be pre-buried and welded, but only needs to be placed on the wall column reinforcement frame, and then the position of the positioning column 2 is adjusted to make the outermost surface flush with the wall column positioning line, so that the device has good stability, is convenient to install, and can accurately adjust the root positioning of the wall column formwork.

[0026] As shown in the embodiment 1, Figures 1-3 As shown in the embodiment 2, the adjustable positioner for the root of the reinforced concrete wall column is further preferred, the positioning rod comprises a horizontal stirrup 4 and a vertical stirrup 5, the horizontal stirrup 4 is connected below the sleeve 1, the vertical stirrup 5 is connected above the sleeve 1, and the plane where the horizontal stirrup 4 is located is perpendicular to the plane where the vertical stirrup 5 is located. The length of the horizontal stirrup 4 and the vertical stirrup 5 is greater than the distance between the adjacent reinforcements of the reinforcement frame, the horizontal stirrup 4 and the vertical stirrup 5 are connected to form a T-shaped structure through the sleeve 1, so that the sleeve 1 can be clamped on the reinforcement frame, and then the device can be tightly arranged between the reinforcement frame and the formwork when the formwork is installed.

[0027] In this embodiment, the horizontal stirrup 4 and the vertical stirrup 5 are both steel bars. The diameter of the steel bar is smaller than the diameter of the reinforcement frame, and the positioning rod formed by the steel bar is used to form a positioning frame. The end of the horizontal stirrup 4 and the end of the vertical stirrup 5 are provided with a hook 6. The hook 6 is arranged on the horizontal stirrup 4 and the vertical stirrup 5, and is used for positioning the device. The hook 6 of the horizontal stirrup 4 and the hook 6 of the vertical stirrup 5 are opposite in direction. The device is prevented from falling off accidentally during pouring, and the stable installation of the device on the wall column reinforcement frame is further ensured, and the installation stability is good.

[0028] In this embodiment, the sleeve 1 is internally threaded. The internal thread can form a threaded connection, and the threaded connection has a self-locking function while achieving adjustment. The sleeve 1 is a hexagonal nut. The hexagonal nut is easy to obtain, and can be welded with the steel bar to form a positioning frame.

[0029] In this embodiment, the positioning post 2 has an external thread that mates with the kit 1. The positioning post 2 engages with the internal thread on the kit 1 through the external thread, resulting in a simple and stable fit. The positioning post 2 is a plastic screw post. Using plastic screw posts is simple to source, lightweight, and ensures effectiveness while avoiding significant wear on the wall column template. The positioning post 2 has a cross-shaped groove 3. The cross-shaped groove 3 facilitates adjustment of the positioning post 2's position, ensuring its outermost end face is flush with the wall column positioning line.

[0030] All other structures are the same as in Example 1.

[0031] like Figures 1-3 As shown in Embodiment 3, an adjustable positioning device for the base of a reinforced concrete wall column includes a plastic screw post, a hexagonal nut, a horizontal hook steel bar, and a vertical hook steel bar. The positioning device's fixing frame is formed by welding the horizontal and vertical hook steel bars to the hexagonal nut to create a single unit. The plastic screw post and hexagonal nut assembly enables distance adjustment. One end of the plastic screw post is flat, and the other end has a cross-shaped groove, with one groove being longer than the other to allow both Phillips head and flathead screwdrivers to be used to adjust the distance. Adjustment is convenient, and the number of screws used can be adjusted according to actual needs, ensuring the accuracy of wall column pouring.

[0032] The specific operation process is as follows: After the floor slab concrete is poured, the engineering surveyors mark the wall and column edge lines. Workers can then suspend the wall and column positioning device from this solution onto the horizontal stirrups and vertical reinforcing bars of the wall and column. This method allows for quick fixation of the device to the wall and column reinforcing bars. By observing whether the end face with the cross-shaped groove on the plastic screw post is aligned with the wall and column edge line, if misalignment occurs, a screwdriver is inserted into the groove of the plastic screw post and adjusted to align the end face with the wall and column edge line for precise positioning. When the wall and column formwork is closed, the base of the formwork is tightly pressed against the end face of the plastic screw post of the positioning device, ensuring quick and accurate positioning of the geometric dimensions of the wall and column base and the thickness of the reinforcing bar protective layer. This positioning device assists in positioning the base of the wall and column formwork, and by using the base positioning as a reference to adjust the verticality of the formwork, the entire wall and column facade is correctly positioned. This positioning device is easy to install, adjustable, uses inexpensive materials, has a simple structure, and can be mass-produced on an assembly line.

[0033] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
