Description

Technical Field

[0001] The utility model relates to the technical field of measuring tools, in particular to a camber degree measuring tool. Background Art

[0002] Arching refers to the measure taken to increase the mid-span height in advance during the construction of large-span floors or roof beams and slabs in order to improve the visual illusion and correct the self-weight settlement. The so-called arching degree is the height difference between the two ends of the span and the middle of the span.

[0003] The commonly used instrument for measuring the arch is the level, which is convenient and fast, but the use of the level requires a certain amount of space. When measuring the arch of the top suspension beam indoors, it is not convenient to use the level to measure the arch of the suspension beam due to limited space. Manual measurement of the arch is usually to connect the two ends of the suspension beam with a rope (or line), and then use a steel ruler to measure the distance from the middle of the suspension beam to the rope (or line). This measurement method is not accurate enough and requires the measurer to climb up to tie the rope (or line) to the two ends of the suspension beam, which makes the measurement more troublesome.

[0021] In the specific implementation process, Figure 1 and Figure 2 As shown, it includes a main head 2, which is a cylindrical structure. Storage sleeves 3 are symmetrically arranged on both sides of the main head 2. The storage sleeves 3 are integrally connected to the main head 2. An extension sleeve 4 is slidably connected inside the storage sleeve 3. A measuring plate 5 is slidably connected inside the extension sleeve 4. A support column 1 is arranged below the main head 2. The upper end of the support column 1 is rotatably connected to the main head 2. A measuring rod 9 is arranged inside the support column 1. The measuring rod 9 is threadedly connected to the support rod. A first storage slide groove is provided on the side of the end of the extension sleeve 4 away from the main head 2 6. The first receiving chute 6 is of a C-shaped structure. The extension sleeve 4 is arranged in the first receiving chute 6 and is slidably engaged with the receiving sleeve 3. The end of the first receiving chute 6 away from the main head 2 is an open end, and the opening is retracted inward. One end of the extension sleeve 4 can slide out of the first receiving chute 6 smoothly. The other end of the extension sleeve 4 has a convex block on the side. The extension sleeve 4 cooperates with the retracting structure of the open end of the first receiving chute 6 through the convex block to prevent the extension sleeve 4 from directly sliding out of the first receiving chute 6 and separating from the receiving sleeve 3.

[0022] refer to Figure 2 and Figure 3As shown, a second receiving chute 7 is provided on the side of the extension sleeve 4 near one end of the main head 2. The second receiving chute 7 is a T-shaped structure, and the second receiving chute 7 is a closed structure at one end away from the main head 2. A T-shaped connecting slider 8 is integrally connected to the lower surface of the measuring plate 5 near one end of the main head 2. The measuring plate 5 is slidably embedded in the second receiving chute 7 and slidably connected to the extension sleeve 4 through the connecting slider 8. The measuring plate 5 is a straight thin plate, which is convenient for aligning with the end of the cantilever beam during measurement. The measurement can be slid to the extension sleeve 4 through the connecting slider 8. The sleeve plate 4 is far away from one end of the main head 2, and due to the closed structure of this end, the measuring plate 5 is prevented from directly sliding out of the second receiving slide groove 7 and detaching from the extended sleeve plate 4. A connecting hole 10 is provided on the surface of the main head 2, and the connecting hole 10 is a through hole structure. An adapter groove 11 is provided on the lower surface of the main head 2, and a locking block 12 is provided at a symmetrical position to the adapter groove 11. The locking block 12 is fixedly connected to the main head 2, and the symmetrical sides of the locking block 12 are respectively connected with card blocks through springs, and the card blocks can be movably embedded in the locking block 12.

[0023] refer to Figure 2 and Figure 4 As shown, a through hole is provided on the surface of the support column 1, and a thread is engraved inside the through hole. The measuring rod 9 is arranged inside the through hole and is threadedly connected to the support column 1. A locking base 13 is fixedly connected to the side of the upper end of the support column 1. An adapter block 14 is symmetrically provided at the locking base 13. The adapter block 14 is fixedly connected to the support column 1. The support column 1 is embedded in the adapter groove 11 through the adapter block 14 and is rotatably connected to the main head 2. A groove is provided on the upper surface of the locking base 13, and card grooves are respectively provided on the symmetrical sides of the groove. The card groove on the locking base 13 is adapted to the card block on the locking block 12. When the locking block 12 is embedded in the groove of the locking base 13, the card The block enters the card slot to lock the locking block 12 and the locking base 13. The support column 1 is fixedly connected to the main head 2 through the locking base 13. The lower end surface of the measuring rod 9 is engraved with a thread, and the upper end surface of the measuring rod 9 is engraved with a measuring scale 15. The top of the measuring rod 9 has a certain arc-shaped protrusion. When the top plane of the measuring rod 9 passes through the connecting hole 10 and is flush with the upper surface of the main head 2, the protrusion peak on the top of the measuring rod 9 is just flush with the upper surface of the measuring plate 5. The threaded connection between the measuring rod 9 and the support rod can enable the measuring rod 9 to maintain the measuring state unchanged after the measurement is completed. The user can place the support rod horizontally to facilitate reading the measuring rod 9.

[0024] The working principle provided by the utility model is as follows: when the utility model is not in use, in order to facilitate storage and carrying, the measuring plate 5, the extension sleeve 4 and the storage sleeve 3 should be overlapped as one, and the support column 1 is rotated to be parallel to the extension sleeve 4 on one side, showing a folded state. When the utility model is in use, the support column 1 is first rotated to a vertical state with the extension sleeve 4, and the support column 1 is locked and connected with the main head 2 by the locking base 13 and the locking block 12. Then, the measuring plate 5 and the extension sleeve 4 are unfolded to a suitable length as needed, and it is ensured that the two groups of measuring plates 5 are symmetrical with the main head 2 as the center, and then the two groups of measuring plates 5 are contacted with the two ends of the suspension beam, and then the measuring rod 9 is rotated so that the top of the measuring rod 9 contacts the middle of the suspension beam, and then the measuring rod 9 is read. After the measurement is completed, the device is stored and folded again to the original state of use.
