[0002] As an indispensable key technical equipment in modern construction, the formwork frame provides a strong formwork support system for concrete pouring operations through its precise design and stable structure. It not only ensures that the formwork maintains a precise shape and position during the pouring process, effectively preventing concrete deformation or leakage, thereby significantly improving the pouring quality; at the same time, the rapid erection and disassembly capabilities of the formwork frame also greatly accelerate the construction progress, reduce labor intensity, and improve construction efficiency.

[0034] In the specific implementation structure, multiple groups of telescopic components 2 are arranged around the central seat 1, one end of the telescopic component 2 is fixed on the central seat 1, and the extension end thereof extends outward. In this embodiment, two telescopic components 2 are arranged, and are respectively distributed on both sides of the central seat 1, and the two telescopic components 2 are in a line, and a corresponding measuring body is arranged on the rear side of each telescopic component 2.

[0035] As an example, the telescopic assembly 2 includes a sleeve rod 201, a sleeve 202 and a top screw 203, wherein the sleeve rod 201 is arranged on the center seat 1, the sleeve 202 is sleeved on the sleeve rod 201, and can be locked by the top screw 203; of course, it can also be other structures such as an electric push rod, a telescopic hydraulic cylinder; or a reverse-threaded screw in the middle and screw barrels on both sides, and the length is adjusted by rotating the screw in the middle, and other structures for linear length adjustment are all possible.

[0036] The structure of the measuring body mainly includes the following contents: an adjusting seat 3, a top rod 4, an upper clamping seat 5, a rocker arm 6 and a lower clamping seat 7; in the specific connection structure, the adjusting seat 3 is fixed to the telescopic end of the telescopic component 2, and the telescopic end also serves as an installation base, and a level bubble meter 24 is arranged on the telescopic component 2 or the adjusting seat 3, and one or more level bubble meters 24 are arranged for leveling operations to provide a horizontal reference for the device.

[0037] A push rod 4 is fixed to the side of the adjusting seat 3, and an upper clamping seat 5 is hinged at the end of the push rod 4. The structure of the push rod 4 is consistent with the telescopic direction of the telescopic component 2. When the telescopic component 2 is leveled, the push rod 4 is also in a horizontal state. The length of the push rod 4 is fixed, but its position will change with the elongation of the telescopic component 2, that is, the distance between the hinge point of the upper clamping seat 5 and the adjusting seat 3 is a fixed value, which can be taken as needed, such as a.

[0038] The rocker arm 6 is hinged on the adjustment seat 3, and its end is hinged with the lower clamping seat 7; on the upper end of the rocker arm 6, its overall length is fixed, that is, the distance between the hinge point of the lower clamping seat 7 and the adjustment seat 3 is a fixed value, which can be taken as b as needed.

[0039] Corresponding card slots are provided on the upper card seat 5 and the lower card seat 7. The upper card seat 5 and the lower card seat 7 have the same structure, so that the line connecting the hinge points of the upper card seat 5 and the lower card seat 7 can represent the inclination state of the measured column. During implementation, the card slot in this embodiment is a semi-circular arc structure, and the semi-circular arc card slot can be adaptably mounted on the column 15.

[0040] A vertical rod 10 is provided at the lower part of the center seat 1, and a base 11 is fixed at the lower part of the vertical rod 10. A driving rod 9 with hinged ends is provided between the base 11 and the rocker arm 6 to keep the swing angle of the rocker arm 6 in a fixed state. The driving rod 9 is a length-adjustable structure, and it can also be locked after the length is adjusted like the structure of the telescopic component 2.

[0041] As a measurement standard, in this embodiment, the upper end of the rocker arm 6 is hinged on the adjustment seat 3 through the first rotating shaft 12, and the first rotating shaft 12 is connected to the angle sensor 8. The angle obtained by the angle sensor 8 is the angle α between the horizontal top rod 4 and the rocker arm 6. Through the value of the angle, according to the triangle principle, the length of its relative side can be first determined, that is, the three side lengths and one angle of the triangle are determined, and then the angles of the remaining two angles can be immediately obtained, and then the inclination angle of the column 15 can be obtained.

[0042] In order to ensure the clamping effect of the upper clamping seat 5 and the lower clamping seat 7, in this embodiment, magnets can be configured on the sides of the upper clamping seat 5 and the lower clamping seat 7, and magnetic attraction can be used to strengthen the clamping state of the upper clamping seat 5, the lower clamping seat 7 and the column 15.

[0043] In order to facilitate measurement, in this embodiment, the upper clamping seat 5 is hinged to the end of the top rod 4 through the second rotating shaft 13, and the second rotating shaft 13 is at the same level as the first rotating shaft 12, that is, the connecting line of the hinge point of the upper clamping seat 5 and the hinge point of the swing rod 6 is in a horizontal state after leveling, and the lower clamping seat 7 is hinged to the end of the swing rod 6 through the third rotating shaft 14. Figure 6 As shown in , a triangle is constructed with the first rotating shaft 12, the second rotating shaft 13 and the third rotating shaft 14, and the angle of one angle is determined by measurement. At the same time, the lengths of the two sides are known, so the length of the opposite side is obtained by the trigonometric function, and then the inclination angle of the column 15 is obtained. For example, during the measurement, the lengths of a and b are fixed values. If the measured angle is α 1 , then the column 15 is in a standard vertical state. If the angle sensor 8 measures an angle α 2 , then the deflection angle of the column 15 is β.

[0044] When in use, the present embodiment first selects two columns 15, adjusts the length of the telescopic assembly 2, and fits the upper clamping seats 5 on both sides onto the columns 15 accordingly, further extends the telescopic assembly 2, and ensures that the upper clamping seats 5 are tightly fitted to the outer surface of the column 15, then locks the telescopic assembly 2, swings the rocker arm 6, and makes the lower clamping seat 7 tightly mounted on the surface of the column 15 like the upper clamping seat 5, then locks the drive rod, reads the reading of the angle sensor, and after the reading is subjected to the above-mentioned logical conversion, the inclination of the column 15 can be obtained.

[0045] Embodiment 2: This embodiment provides another measurement method for the structure in Embodiment 1, or further provides a measurement method for auxiliary verification based on Embodiment 1.

[0046] In this embodiment, a rotating seat 17 is rotatably arranged at the bottom of the base, and a horizontal laser emitter 18 is fixed to the side of the rotating seat 17. The lower clamping seat 7 is hinged to the end of the swing rod 6 through the third rotating shaft, and a marking point is arranged at the center of the third rotating shaft 14.

[0047] In this embodiment, the laser emitter can emit horizontal visible red light, and a standard plane can be formed on the circumference as it rotates. The laser emitter is directed to the third axis and compared with the marking point. If the two coincide, it indicates that the column 15 is in a vertical state. If it is deflected upward or downward, it means that the column 15 is in a deflected state. The degree of deflection of the column 15 is further judged according to the deflection amount, so as to quickly determine whether the state of the column 15 meets the standard. Combined with the deflection amount or the calculation method in Example 1, the specific deflection parameters of the column 15 are further determined.

[0048] Embodiment 3: This embodiment describes the specific implementation quantity of the telescopic component 2.

The telescopic assembly 2 also includes a movable telescopic assembly 20, which is rotatably mounted on the center seat 1 so that the movable telescopic assembly 20 can adjust its angle relative to the center seat 1.

[0050] In this embodiment, the fixed state of the center seat 1 is determined by fixing the telescopic component 19, the center seat 1 is leveled using the horizontal bubble meter 24, and the movable telescopic component 20 is used to adaptively correspond to the corresponding column 15, and then the verticality of the corresponding column 15 is measured in the manner of Example 1.

[0051] Structurally, a slide groove 22 is provided on the side of the center seat 1, and the movable telescopic component 20 is slidably inserted into the slide groove 22 through a slider 21. As the telescopic component 2 is extended, the upper clamping seat 5 at its outer end is clamped on the column 15. After the telescopic component 2 is locked, it is kept in the slide groove with the help of a supporting force.

[0052] This embodiment provides a multi-point verticality measurement device for verticality measurement of multiple columns 15, which greatly simplifies the measurement difficulty. Through one-time leveling, the verticality measurement purpose of multiple columns 15 is achieved with the existing columns 15 to be measured as a fixed foundation.

[0053] Embodiment 4: This embodiment describes the structure of the card slot.

[0054] In this embodiment, Figure 5 As shown in the figure, the slot is an isosceles trapezoidal structure 16, and the hinge point of the upper holder 5 and the lower holder 7 is located on the center line of the slot. This embodiment can adapt to different diameters of the column 15, that is, different cylindrical rods, through the trapezoidal slot structure, and has better adaptability to meet people's different usage needs.
