Description

Technical Field

[0001] The utility model relates to the technical field of building construction and assembly, in particular to a nut twisting device for leveling and measuring the distance of suspended ceiling keels. Background Art

[0002] With the development of society and advancements in technology, the traditional construction industry faces a series of challenges. The same is true for the decoration industry, with rising labor wages and uneven technical skills. Although suspended ceilings are a relatively simple task in the entire decoration construction process, the flatness of most constructed ceilings still needs to be adjusted and improved. This is especially true for large-scale suspended ceilings, and quality control remains a critical task.

[0003] In the current suspended ceiling construction, the keel leveling quality requirements are all leveled by using an infrared level meter + tape measure. Because the tape measure distance is carried out on a stepladder and is manual, it is relatively arbitrary, and the ceiling leveling and installation height accuracy are insufficient. Utility Model Content

[0004] The purpose of the utility model is to provide a nut twisting device for leveling and measuring the distance of a ceiling keel in order to solve the problems that the conventional manual distance measurement and leveling method is relatively random and the ceiling leveling and installation height accuracy are insufficient.

[0005] In order to achieve the above-mentioned purpose, the present invention adopts the following technical solution: a nut-tightening device for leveling and measuring the distance of a ceiling keel, comprising:

[0006] The hand-held screwing section has scale lines on multiple sides;

[0007] The nut sleeve section has its end face abutted against the surface of the ceiling keel or ceiling connector, and a sleeve is opened on its end face. The sleeve is sleeved on the nut threaded on the hanger or connecting rod that connects to the ceiling keel or ceiling connector. The scale line is used in conjunction with the spirit level arranged at the construction site, and the light emitted by the spirit level is vertically directed toward the scale line.

[0008] As a further description of the above technical solution:

[0009] The scale accuracy of the scale lines is 1 mm.

[0010] As a further description of the above technical solution:

[0011] The hand-held screwing section and the nut sleeve section are a polygonal cylindrical structure as a whole, and the scale lines are arranged at intervals on the side of the polygonal cylindrical structure.

[0012] As a further description of the above technical solution:

[0013] The hand-held screwing section and the nut sleeve section are overall in a "7"-shaped structure, the ends of the hand-held screwing section and the nut sleeve section are vertically connected, and the nut sleeve section is in a C-shaped structure.

[0014] As a further description of the above technical solution:

[0015] The level is an infrared level.

[0016] In summary, due to the adoption of the above technical solution, the present invention has the following advantages compared with the prior art:

[0017] Beneficial effects:

[0018] The utility model uses a special nut tightening device for leveling and measuring distance to tighten the nut. Compared with manually tightening the bolt, the nut tightening speed is greatly improved, and the efficiency is improved. Compared with the randomness of measuring distance with a tape measure, the nut sleeve section is sleeved on the nut and abuts against the end face of the keel or its connecting piece for positioning, which plays a positioning role. In conjunction with the infrared level meter and the scale line setting on the device, the accuracy of the reading is improved, thereby improving the levelness of the keel and the adjustment accuracy of the installation height.

[0028] See also Figure 1-4 The utility model provides a technical solution: a nut tightening device for leveling and measuring the distance of a ceiling keel, comprising:

[0029] The hand-held screwing section 1 has scale marks 4 on multiple sides thereof;

[0030] The nut sleeve section 2 has its end face abutted against the surface of the ceiling keel 10 or the ceiling connector 12, and a sleeve 3 is opened on its end face. The sleeve 3 is sleeved on the nut 13 screwed on the hanger 11 or the connecting rod that connects to the ceiling keel 10 or the ceiling connector 12. The scale line 4 is used in conjunction with the spirit level arranged at the construction site, and the light emitted by the spirit level is vertically directed toward the scale line 4.

[0031] The scale line 4 has a scale accuracy of 1 mm. The level is an infrared level. This design improves the keel leveling and assembly height accuracy.

[0032] In one embodiment, the hand-held screwing section 1 and the nut sleeve section 2 are a polygonal cylindrical structure as a whole, and the scale lines 4 are arranged at intervals on the side of the polygonal cylindrical structure.

[0033] The purpose of this utility model is to control the flatness of the ceiling assembly and improve the construction efficiency. The nut twisting device is a metal component with a hollow interior. Its inner cavity can adopt a regular hexagonal structure, and the thickness can be designed to be 3mm. The inner diameter corresponds to the outer diameter of various specifications of nuts such as M6 and M8, so as to adapt to the socketing and twisting assembly of regular hexagonal nuts of various sizes. On the external facade of the product, every other side is marked with a scale, and a total of three sides of the six sides are marked with scales. The length of the component can be customized as needed, preferably 15-30cm. This product is suitable for ceiling forms using U-shaped keels, such as Figure 2 The height of the U-shaped keel is adjusted mainly by twisting the nut on the boom used to fix the U-shaped keel, so as to achieve the purpose of adjusting the flatness of the keel.

[0034] The working principle of a nut tightening device for leveling and measuring the distance of a suspended ceiling keel in this embodiment includes the following steps: during construction and assembly, after the base suspended ceiling keel 10 is installed, a temporary operating platform is made on the partition wall and an infrared level is set up; the scale value of infrared irradiation when the nut 13 is assembled in place is calculated according to the suspended ceiling elevation and the installation distance of the suspended ceiling keel 10, the suspension rod 11, and the nut 13; the sleeve 3 of the sleeve (nut sleeve section 2) is put on the nut 13 used to fix (limit) the suspended ceiling keel 10, the handheld tightening section 1 is rotated, and the nut 13 is tightened synchronously. When the value of the infrared ray mapped to the sleeve meets the above-calculated data, the tightening is stopped, that is, the local height of the suspended ceiling keel 10 reaches the required height for the designed installation; and by analogy, the nut 13 on each suspension rod 11 is tightened so that each suspended ceiling keel 10 is at the same horizontal height, and the assembly is completed.

[0035] Compared with the common manual distance and level measurement using a tape measure, this design uses a special leveling and distance measuring sleeve to tighten the nut. Compared with manual tightening of the nut, it greatly improves the tightening speed of the nut and improves the efficiency. Compared with the randomness of measuring distance with a tape measure (the infrared light is not vertical and the reading has errors), the sleeve is put on the nut to fix it, which improves the accuracy of the reading and thus improves the adjustment accuracy of the levelness of the keel.

[0036] In another embodiment, the hand-held screwing section 1 and the nut sleeve section 2 are overall in a "7"-shaped structure, the ends of the hand-held screwing section 1 and the nut sleeve section 2 are vertically connected, and the nut sleeve section 2 is a C-shaped structure.

[0037] The upper part of the product in this embodiment is a bend head. The size of the arc-shaped concave part of the bend head corresponds to the outer diameter of various specifications of nuts such as M6 and M8, which can realize the screwing of various types of nuts. The lower part is a hand-held twisting part and is marked with scale. The length of the lower part of the component can be customized as needed, preferably 15-30cm, as shown in the following example. Figure 4This product is suitable for all types of suspended ceilings that use keels. The hanging height is adjusted mainly by twisting the nut on the hanger rod used to fix the hanging, so as to achieve the purpose of adjusting the flatness of the keel.

[0038] The working principle of a nut tightening device for leveling and measuring the distance of a ceiling keel in this embodiment includes the following: during construction and assembly, after the base ceiling keel 10 is installed, a temporary operating platform is made on the partition wall and an infrared level is set up; the scale value of infrared irradiation when the nut 13 is assembled in place is calculated according to the ceiling elevation and the installation distance of the ceiling keel 10, the hanger 11, the keel connector 12, and the nut 13; the bend head is put on the nut used to fix (limit) the keel, and the nut is twisted. When the value mapped by the infrared ray to the bend hand meets the above-calculated data, the twisting is stopped, that is, the keel height reaches the design installation requirement height; and so on, the nut on each hanger is twisted so that all keels reach the design arch height.

[0039] The nuts are tightened by using a special leveling and distance measuring lever. Compared with manual tightening of bolts, the speed of tightening the nuts is greatly increased, and the efficiency is improved. Compared with the randomness of measuring distance with a tape measure (the infrared light is not vertical and the reading has errors), the lever is put on the nut to fix it, which improves the accuracy of the reading and thus improves the adjustment accuracy of the levelness of the keel.

[0040] The above is only a preferred specific implementation method of the present invention, but the protection scope of the present invention is not limited to this. Any technician familiar with the technical field within the technical scope disclosed by the present invention can make equivalent replacements or changes based on the technical solution and utility model concept of the present invention, which should be covered by the protection scope of the present invention.
