Description

Technical Field

[0001] This utility model relates to the field of measurement and calibration technology, and in particular to a precast composite slab construction measurement device. Background Technology

[0002] Composite slabs are commonly used precast components in prefabricated concrete structures. The core of them is the combination of "precast + cast-in-place", which combines the efficiency of precast components with the integrity of cast-in-place structures. They usually consist of two parts: a precast base slab (with its own reinforcing steel bars, and some also have reserved truss bars) precast in the factory, and a cast-in-place concrete composite layer. During installation, the precast base slab is first hoisted into place and fixed, and then the reinforcing steel bars are tied on top of it and concrete is poured to finally form an integrally load-bearing floor slab or wall panel.

[0003] After the existing precast composite slabs are poured, they need to be measured and calibrated. During the pouring process, there are significant drawbacks that can affect subsequent use. These drawbacks are mainly as follows: First, after the composite slabs are poured, the surface of the slabs is prone to unevenness. If they are installed directly, it can easily affect the subsequent surface layer construction. Second, the composite slabs are of different sizes, so different measuring equipment is required for measurement.

[0004] Therefore, a construction measurement device for precast composite slabs is needed. Utility Model Content

[0005] The present invention proposes a precast composite slab construction measurement device, which solves the problem that in the prior art, after the composite slab is poured, the surface of the composite slab is prone to unevenness, which can easily affect the subsequent surface layer construction if it is installed directly; on the other hand, the composite slabs are of different sizes, and different sized measuring equipment is required for measurement.

[0006] To achieve the above objectives, this utility model provides the following technical solution: A precast composite slab construction measuring device includes a level, the bottom of which is provided with a level top plate, and the bottom side of the level top plate is provided with a detachable adjustable threaded shaft. An adjusting compass is fitted onto the surface of the adjusting threaded shaft. A limiting sleeve is provided at the bottom of the adjusting compass. A groove is provided around the periphery of the limiting sleeve. A horizontal plate is embedded in the groove. A detachable threaded base post is provided at the bottom of the adjusting threaded shaft. The bottom of the threaded column is provided with a horizontal base plate.

[0007] Preferably, the horizontal top plate and the adjusting threaded shaft are connected by a rotating head to form a rotating structure, and the adjusting compass and the limiting sleeve are integrally welded.

[0008] Preferably, the side of the horizontal base plate is provided with a detachable locking groove, the end of the locking groove is provided with a limiting slide groove, the top of the limiting slide groove is provided with a telescopic frame, and the bottom of the telescopic frame is provided with a detachable bottom wheel.

[0009] Preferably, the telescopic frame has a sliding shaft on the bottom side of its end, the sliding shaft is embedded in the limiting groove to form a sliding structure, and the sliding shaft near the end of the limiting groove has a locking and rotating structure with the limiting groove.

[0010] Preferably, the horizontal base plate has a groove horizontally formed inside, and the locking tooth groove is embedded in the groove to form a sliding structure.

[0011] Preferably, the center axis of the locking groove is provided with a detachable limiting connecting slide plate, the top side of the limiting connecting slide plate is provided with a telescopic spring, and the end of the telescopic spring is provided with a pressing block.

[0012] Preferably, the bottom end of the limiting groove is provided with a connecting sleeve, and a bidirectional threaded rod is embedded in the connecting sleeve. Both ends of the bidirectional threaded rod are provided with baffles for limiting.

[0013] This utility model proposes a construction measurement device for precast composite slabs. Compared with the prior art, the beneficial effects of this utility model are: 1. By setting the adjusting threaded shaft, adjusting compass, and threaded base, the level can be precisely adjusted to achieve an absolutely level state, which facilitates subsequent inspection of the unevenness of the plate surface; when using the level, in order to ensure that the level reaches the standard state, the angle of the adjusting compass can be rotated to control the raising and lowering of the adjusting threaded shaft, ensuring that the leveling plate and the level are level, which facilitates subsequent inspection work after the initial calibration; 2. By setting up locking slots, a telescopic frame, and a two-way threaded rod, a wide range of measurement and calibration operations can be performed on composite plates of different sizes. After the telescopic frame extends or retracts, the spacing of the limiting slide grooves will change. To ensure that the level and its accessories can be used for measurement operations, the actual distance of the pressing block on the locking slot can be adjusted by pressing the pressing block, thereby adjusting the sliding distance of the level base plate in the locking slot and fixing it in place. This ensures that the spacing of the limiting slide grooves remains unchanged during the movement of multiple sets of base wheels, ensuring the measurement accuracy of the level. At the same time, by using the connecting sleeve and the two-way threaded rod, a device for large-scale repeated measurement and calibration can be built, improving the accuracy of the measurement.

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-5 This utility model provides a technical solution: a precast composite slab construction measurement device, including a level 1, a level top plate 2 at the bottom of the level 1, and a detachable adjustable threaded shaft 3 on the bottom side of the level top plate 2. An adjusting compass 4 is fitted onto the surface of the adjusting threaded shaft 3. A limiting sleeve 5 is provided at the bottom of the adjusting compass 4. A groove is provided around the limiting sleeve 5. A horizontal plate 6 is embedded in the groove. A detachable threaded base post 7 is provided at the bottom of the adjusting threaded shaft 3. The bottom of the threaded column 7 is provided with a horizontal base plate 8.

[0018] Furthermore, the horizontal top plate 2 and the adjusting threaded shaft 3 are connected by a rotating head to form a rotating structure, and the adjusting compass 4 and the limiting sleeve 5 are connected by an integral welded structure; rotating the angle of the adjusting compass 4 controls the raising and lowering of the adjusting threaded shaft 3 to ensure that the horizontal top plate 2 and the level 1 are in a horizontal state. After the initial calibration, it is convenient for subsequent testing operations.

[0019] Furthermore, the side of the horizontal base plate 8 is provided with a detachable locking groove 9, the end of the locking groove 9 is provided with a limiting slide groove 13, the top of the limiting slide groove 13 is provided with a telescopic frame 14, and the bottom of the telescopic frame 14 is provided with a detachable bottom wheel 15; the setting of the telescopic frame 14 can adjust the distance between the two sets of limiting slide grooves 13, thereby realizing the measurement and calibration operation of large-size composite plates.

[0020] Furthermore, a sliding shaft is provided on the bottom side of the end of the telescopic frame 14. The sliding shaft is embedded in the limiting slide groove 13 to form a sliding structure. The sliding shaft near the end of the limiting slide groove 13 is engaged with the limiting slide groove 13 to rotate. The setting of the sliding shaft can ensure that the telescopic frame 14 can complete stable sliding within the limiting slide groove 13. In order to prevent the telescopic frame 14 from shifting its position when sliding, the sliding shaft near the end of the limiting slide groove 13 is set in an engaging structure to provide a limiting function.

[0021] Furthermore, a groove is horizontally provided in the horizontal base plate 8, and the locking tooth groove 9 is embedded in the groove to form a sliding structure; this ensures that when the distance of the limiting slide groove 13 changes, the level 1 and its accessories can complete the horizontal measurement operation.

[0022] Furthermore, a detachable limiting connecting slide plate 10 is provided on the center axis of the locking tooth groove 9. A telescopic spring 11 is provided on the top side of the limiting connecting slide plate 10, and a pressing block 12 is provided at the end of the telescopic spring 11. By pressing the pressing block 12, the actual distance of the pressing block 12 on the locking tooth groove 9 is adjusted, thereby adjusting the sliding distance of the horizontal base plate 8 on the locking tooth groove 9 and completing the fixation.

[0023] Furthermore, a connecting sleeve 16 is provided at the bottom end of the limiting slide groove 13, and a bidirectional threaded rod 17 is embedded in the connecting sleeve 16. Both ends of the bidirectional threaded rod 17 are provided with baffles for limiting. Using the connecting sleeve 16 and the bidirectional threaded rod 17, a device for large-scale repeated measurement and calibration can be built to improve the accuracy of measurement.

[0024] Working principle: The precast composite slab construction measurement device can be operated in the following ways; First, when it is necessary to measure the level of the composite plate, the level 1 can be calibrated first. Rotate the angle of the adjusting compass 4 and control the raising and lowering of the adjusting threaded shaft 3 to ensure that the level top plate 2 and the level 1 are in a horizontal state. After the initial calibration, it is convenient for subsequent inspection operations. At the same time, the rotation of the threaded bottom column 7 and the adjusting threaded shaft 3 can be adjusted to further adjust the level state. Next, by moving the bottom wheels 15 side by side, the uneven areas that appear during the process are detected. If the level 1 deviates, the uneven areas are accurately detected. Then, when it is necessary to perform measurement and calibration work on composite plates of different sizes, the telescopic frame 14 can be operated to extend and retract, and the spacing of the limiting slide groove 13 will change. In order to ensure that the level 1 and its accessories can be used for measurement work, the actual distance of the pressing block 12 on the locking tooth groove 9 can be adjusted by pressing the pressing block 12, thereby adjusting the sliding distance of the horizontal base plate 8 on the locking tooth groove 9 and completing the fixation. This ensures that the spacing of the limiting slide groove 13 remains unchanged during the movement of multiple sets of bottom wheels 15, ensuring the measurement accuracy of the level 1. At the same time, by using the connecting sleeve 16 and the bidirectional threaded rod 17, a device for large-scale repeated measurement and calibration can be built to improve the measurement accuracy.
