[0002] The structural column refers to a reinforced concrete structural column arranged in the wall of a multi-storey brick and concrete structure building to enhance the integrity and stability of the building, and connected with the ring beams of each floor to form a spatial frame capable of resisting bending and shearing, which is an effective measure to prevent the collapse of the building. The structural column is generally arranged at the four corners of the outer wall, the intersection of the cross layer part horizontal wall and the outer longitudinal wall, and the two sides of a large opening. Steel bars need to be planted in the structural column, which is called planting a steel bar to increase the structural strength. The planting of a steel bar should be pre-drilled in the building structure to be supported, and the upper and lower ends of the steel bar are embedded in the hole drilled in the building body. The planting of a steel bar should ensure its verticality to avoid misalignment of the upper and lower ends of the steel bar, otherwise it will cause the bending of the force direction of the steel bar support, and the perpendicularity of the steel bar placement will directly affect the structural strength of the structural column.

[0003] At present, the hole for planting a steel bar in the building body is drilled by visual inspection or line plumb positioning.

[0055] It should be noted that:

[0056] 1. This device does not require a plumb bob for positioning and does not require visual positioning. Instead, it uses a laser locator 3 for calibration. The overall frame of this device serves as a positioning platform, and the entire platform can be adjusted to ensure the accurate position and level of the support platform. When laser positioning the rebar planting holes at the top of the building structure, this device is erected at the floor during drilling, and this device and the drilling tool do not interfere with each other; 2. This device can position the rebar planting of various different structural columns. It can be a structural column with 4 rebar plants, or a structural column with 6 or 8 rebar plants. As long as the laser locator 3 is installed on the planar frame of the connecting rod 11 and the adjusting strut 12 after positioning, the operation is convenient, the positioning is convenient, and the construction is flexible.

[0057] The utility model discloses a positioning device for constructional column, which comprises a center pole, a plurality of connecting rods, a plurality of adjusting struts, a plurality of leveling rods, a plurality of laser positioners and a plurality of leveling instruments.

[0058] The bottom plate is cleaned, and the positions of the anchor bars on the floor are marked. The anchor bars can be marked by chalk or other markers. The marking points of any two opposite anchor bars are connected, and the intersection point obtained is the center point of the constructional column.

[0059] Then, the device is assembled and adjusted, so that the number and assembly angle of the connecting rods 11 and the adjusting struts 12 are adapted to the shape and size of the constructional column. Generally, the number of the connecting rods 11 and the adjusting struts 12 is two, and they are perpendicular to each other to form a cross shape. The actual size and shape of the connecting rods 11 and the adjusting struts 12 are the same, except that the functions are different. The difference is that the two ends of the adjusting struts 12 need to be installed with the stands 2.

[0060] The positioning tube 31 is fixed on the center pole 1 at the center point, and the level 4 can be installed on the center pole 1, the connecting rod 11 and the adjusting strut 12 respectively to ensure that the entire frame remains horizontal. In conventional engineering construction, only one needs to be installed on the center pole 1.

[0061] When positioning the entire frame, first, the center point of the constructional column is positioned. When the line of sight passes through the positioning tube 31 from top to bottom and the intersection center point of the constructional column can be seen, it is considered that the positioning tube 31 is vertically coincident with the center point of the constructional column. A laser positioner 3 can also be used to vertically irradiate downward along the positioning tube 31 once to ensure the accuracy of the position.

[0062] Then, the height of the adjusting rod 22 is adjusted so that the bubble of the level 4 remains in the center to ensure that the entire frame remains horizontal. And the entire frame structure is stably erected.

[0063] Then, the position of the laser positioner 3 is positioned. Because the device is erected on the bottom plate as a whole, the positioning point of the laser positioner 3 and the bottom anchor bar is very small. The bottom of the laser positioner 3 almost adheres to the bottom of the building, and there is no error. The bottom of the laser positioner 3 is aligned with the previously measured point of the anchor bar on the bottom plate. The laser beam at the top of the laser positioner 3 is irradiated to the top of the building structure to achieve the purpose of positioning the upper end of the anchor bar on the top of the building. The laser irradiation positioning remains vertical, and no additional marking is needed. The positioning point has no physical object, and it will not cause the positioning mark to disappear with the continuous drilling, ensuring continuous positioning.

[0064] Then the positioning point of each anchor bar is installed with a laser positioner 3, and after fine adjustment, it is locked to ensure the accurate position of the laser positioner 3. That is, the effect of positioning the upper end of the anchor bar in the embedded hole in the building is achieved. Then, the anchor bar positioning hole at the top of the building is drilled first, and after completion, the device is removed, and the anchor bar hole at the bottom of the building is drilled.

[0065] At this time, the upper and lower ends of the anchor bar hole remain on the same straight line, and the positioning is accurate. The anchor bar position and quantity can be adjusted according to the design of the construction column of each construction building, and the use is flexible.

[0066] And the basic structure of the construction column in the whole building body is the same, the device can be adjusted once and reused until the construction of the whole building body is completed, the operation is simple, after the first adjustment is completed, the subsequent anchor bar hole positioning of the same construction column only needs to measure the anchor bar positioning point of the building bottom plate, then check the positioning pipe 31, make it with the center of the construction column, and then open the laser positioner 3, the operation is simple.

[0067] The top and bottom of the device refer to the top and bottom of the building body, and the indicated orientation or position relationship is based on the orientation or position relationship shown in the drawings, which is only for the convenience of describing the utility model and simplifying the description, and does not indicate or imply that the device or element must have a specific orientation, be constructed and operated in a specific orientation, therefore it cannot be understood as a limitation of the utility model.

[0068] Although the specific embodiments of the utility model are described above, those skilled in the art should understand that the specific examples described are only illustrative, and are not used to limit the scope of the utility model, and equivalent modifications and changes made by those skilled in the art in accordance with the spirit of the utility model should be covered within the scope of protection of the claims of the utility model.
