Description

Technical Field

[0001] The utility model relates to the technical field of vertical components, in particular to a portable vertical component perpendicularity control device. Background Technique

[0002] At present, the traditional methods for measuring the perpendicularity of vertical components are the plumb line measurement or the infrared measurement method, that is, after the formwork of the vertical component is closed and after curing and formwork removal, the plumb line is hoisted at a height or the perpendicularity is measured by using infrared rays after cleaning the site. The distance from the bottom of the vertical line to the root of the component is measured by using a steel tape measure, so as to calculate the surface perpendicularity of the vertical component.

[0003] However, before concrete pouring, after formwork closing and reinforcement measures construction are completed, when using a plumb line to measure perpendicularity at a height, it is necessary to set up a scaffold or use the formwork support of beams and slabs to climb to a height and then use a plumb line to measure, which has certain safety hazards; when using infrared measurement, it may be difficult to control due to factors such as the formwork support and material stacking on site, and the site needs to be cleaned in advance. After concrete pouring, curing and formwork removal, when using a plumb line to measure perpendicularity at a height, it is necessary to set up a scaffold for working at a height and then use a plumb line to measure, the measurement cost is relatively high, and there are certain safety hazards; when using infrared measurement, it is necessary to wait until the site near the vertical component to be measured is cleaned, the ground base is leveled, and there are no safety hazards around before the measurement can be carried out. In addition, it is inconvenient to observe infrared rays during the day, and it is difficult to control the accuracy of the laser plummet. Content of the Utility Model

Rubber pads 5 are pasted on the top and one side of the top square steel pipe 3, and the rubber pads 5 are all on the same axis. A groove is formed at the center of the top of the rubber pad 5, and the nylon rope 18 is placed at the groove. The groove also has the effect of preventing the nylon rope 18 from being worn. Positioning collar rings 4 are arranged on the top and both sides of the top square steel pipe 3 for fixing the nylon rope to prevent the nylon rope from being displaced or slipping. A nylon rope roller device 14 is arranged on the front of the tower ruler 1. The nylon rope roller device 14 is fixed to the tower ruler 1 by self-tapping screws. One end of the nylon rope 18 is arranged on the nylon rope roller device 14 for winding the nylon rope 18. A folding handle 15 is fixedly connected to the outside of the nylon rope roller device 14 for facilitating the retraction and extension of the nylon rope 18. When not in use, the folding handle 15 can be folded and placed. The nylon rope 18 is pulled out from the nylon rope roller device 14 and passes through each positioning collar ring 4 to prevent deviation and slipping.

[0029] Further, tower collars 8 are fixedly connected in sequence along the vertical direction at the top of the tower ruler 1 and at the bottom of the top square steel pipe 3. A tower collar positioning collar ring 13 is fixedly connected to the front of the tower collar 8 by self-tapping screws, and several tower collar positioning collar rings 13 are on the same vertical line.

[0036] Please refer to Figure 4 : Here, after the steel bar binding and formwork installation are completed, the present utility model is used to measure the perpendicularity of the formwork, so as to achieve the effect of pre-control. During the measurement, first determine the storey height (vertical height) of the vertical member to be measured according to the construction drawings, and adjust the length of the tower ruler 1. The reading of the topmost scale marking line of the tower ruler = storey height (- the thickness of the formwork and wooden square of the upper beam and slab) - 20 cm × 2 - 1 cm + 5 cm. Install the bottom square steel pipe 2 and the top square steel pipe 3, and fix the nylon rope 18 and the plumb bob 16. Press the top surface of the present utility model tightly against the formwork of the upper beam and slab, and closely attach the left member two to the main rib steel pipe of the vertical member formwork. Loosen the nylon rope roller device 14 to make the plumb bob 16 fall to the root of the vertical member. Use a steel tape measure to measure the distance between the nylon rope 18 and the root formwork surface, so as to calculate the projected horizontal distance = measured value - steel pipe diameter - wooden square thickness, and then calculate the perpendicularity. The specific calculation method is as Figure 4 performed, and judge whether the perpendicularity of the formwork meets the design and specification requirements according to the calculated value, and make corresponding correction adjustments for those that do not meet the requirements.

[0037] Please refer to Figure 5 : Here, after the concrete pouring of the vertical member is completed and the formwork is removed, the perpendicularity of the concrete surface can be measured, without waiting for the formwork supports of all beam, slab, wall and column members to be removed. During the measurement, first determine the storey height (vertical height) of the vertical member to be measured according to the construction drawings, and adjust the length of the tower ruler. The reading of the topmost scale marking line of the tower ruler = storey height (- the thickness of the formwork and wooden square of the upper beam and slab) - 20 cm × 2 - 1 cm + 5 cm. Fix the nylon rope 18 and the plumb bob 16. Press the top surface of the present utility model device tightly against the formwork of the upper beam and slab, and closely attach the left side to the concrete surface of the vertical member. Loosen the nylon rope roller device 14 to make the plumb bob 16 fall to the root of the vertical member. Use a steel tape measure to measure the distance between the nylon rope 18 and the root formwork surface, so as to calculate the projected horizontal distance ≈ measured value - 0.5 cm, and then calculate the perpendicularity. The specific calculation method is as Figure 5 performed, and judge whether the perpendicularity of the concrete surface meets the design and specification requirements according to the calculated value, and make a measurement record. At the same time, make corresponding chiseling and repair treatments for the members with non-conforming perpendicularity.
