Description

Technical Field

[0001] The utility model belongs to the technical field of concrete structure embedded part processing equipment, in particular to a concrete structure embedded flatness correction device. Background Art

[0002] Concrete embedded parts are metal or non-metal components pre-installed in concrete structures before pouring. These embedded parts are fixed into the concrete to provide additional strength, rigidity, stability, or other functions. The use of embedded parts can improve the overall performance of the structure and make the construction process simpler and more efficient. Concrete embedded parts are prone to localized deformation due to heat during welding, resulting in uneven surfaces. To ensure accurate installation, a flatness correction device is required. This device typically consists of adjustable brackets, a level, a clamp, and other components. The specific form and function may vary depending on the project requirements.

[0003] For example, the Chinese utility model patent with the announcement number CN219503988U discloses a pre-embedded part corrector, which fixes the pre-embedded steel plate through a plurality of slidably adjustable transverse limit plates and longitudinal limit plates, which can effectively prevent the pre-embedded parts from being deformed during welding. The pre-embedded steel plate has good flatness after welding. The transverse limit plates and longitudinal limit plates can be adjusted according to the structure of the pre-embedded steel plate and the welding position of the anchor bar. The embedded parts are easy to weld, the corrector has a simple structure, and is flexible and convenient to use.

[0004] However, in actual use, the device needs to install the transverse limit plate and the longitudinal limit plate in sequence, and then rotate the locking nuts in sequence to complete the fixation of the embedded parts, which reduces the processing efficiency of the embedded parts.

[0005] In summary, there is currently a need for a flatness correction device that can improve the fixing efficiency of embedded parts. Utility Model Content

[0006] The purpose of this utility model is to provide a device for correcting the flatness of pre-embedded concrete structures. This device effectively avoids the problem of reducing the processing efficiency of pre-embedded parts due to the troublesome fixation of pre-embedded parts.

[0007] The technical solution adopted by the utility model to solve the above problems is: a pre-embedded flatness correction device for concrete structures, comprising:

[0008] A base, the top of the base is rotatably connected to a bidirectional screw rod, the bidirectional screw rod is threadedly connected to a moving block, the top of the base is movably connected to a movable plate, the movable plate and the moving block are hingedly connected to a first connecting rod through a hinge, a splint is provided on one side of the movable plate, a cross bar is symmetrically fixedly connected to one side of the splint, and the cross bar and the movable plate are slidably connected, and a spring is provided on the outer sleeve of the cross bar;

[0009] The vertical plate is fixedly connected to the top of the movable plate, and a T-shaped slot is provided on the vertical plate. The internal intervals of the T-shaped slot are slidably connected with a T-shaped slider. Pressure plates are arranged at intervals between the vertical plates, and a second connecting rod is hinged between the T-shaped slider and the pressure plate through a hinge. Through slots are arranged at intervals on the pressure plate, and an adjustment plate is inserted into the through slots. The bottom of the adjustment plate is fixedly connected with a pressure block at intervals.

[0010] A further preferred technical solution is that two groups of bidirectional screw rods are arranged, respectively arranged on both sides of the top of the base, one end of the two groups of bidirectional screw rods are coaxially fixedly connected to the transmission gear, the two groups of transmission gears are connected by a transmission toothed belt, and one end of the bidirectional screw rod is coaxially fixedly connected to the handwheel.

[0011] A further preferred technical solution is that: two groups of movable plates are provided, both of which are arranged on the top of the base.

[0012] A further preferred technical solution is that: a guide block is fixedly connected to the bottom of the movable plate, and a guide groove is provided at the top of the base at a position corresponding to the guide block and is slidably connected to the guide block.

[0013] A further preferred technical solution is that the end of the cross bar is fixedly connected to a limit plate.

[0014] A further preferred technical solution is that: both ends of the spring are fixedly connected to the movable plate and the clamping plate respectively.

[0015] A further preferred technical solution is that: an anti-slip pad is provided on the splint.

[0016] A further preferred technical solution is that: two groups of moving blocks are provided, both of which are threadedly connected to the outside of both sides of the bidirectional screw rod.

[0018] A further preferred technical solution is that the T-shaped slide grooves are provided on opposite surfaces of the two groups of vertical plates.

[0019] In summary, the present invention has the following advantages:

[0020] 1. The utility model makes it easy to install the pressure plate and the pressure block at the same time through the sliding cooperation between the T-shaped slider and the T-shaped slot, and also makes it easy to quickly adjust the position of the pressure plate. The sliding cooperation between the adjustment plate and the through slot makes it easy to quickly adjust the position of the pressure block. The operation is simple and effectively improves the fixing efficiency of the embedded parts.

[0021] 2. The utility model drives two sets of bidirectional screws to rotate simultaneously by rotating the hand wheel and under the transmission cooperation between the transmission gear and the transmission toothed belt. The rotation of the bidirectional screw will drive the two sets of movable blocks threadedly connected thereto to move toward each other. By utilizing the hinge action between the movable block and the movable plate and the first connecting rod, and the sliding cooperation between the guide block and the guide groove, the two sets of movable plates can be pushed to move horizontally toward each other, thereby pushing the two sets of clamping plates to approach the embedded parts and clamp them. This not only improves the stability of the embedded parts during welding, but also prevents the embedded parts from skewing, which causes the downward pressure position to deviate and affects the correction effect of the embedded parts. The operation is simple.

[0022] 3. The utility model can prevent sparks from splashing when the embedded parts are welded by setting up vertical plates, which effectively protects the workers.

[0023] 4. In the process of clamping the embedded parts by driving the clamping plates to move toward each other, the movement of the two sets of movable plates will also drive the two sets of vertical plates to move toward each other. The movement of the two sets of vertical plates toward each other will also drive the T-shaped sliders on both sides to move toward each other. By utilizing the hinge effect between the T-shaped slider and the pressure plate and the second connecting rod, the pressure plate and the pressure block can be driven at the same time to press down and fix the embedded parts, thereby further improving the fixing efficiency of the embedded parts.

[0030] The present invention will be described in further detail below with reference to the accompanying drawings.

[0031] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by patent law.

[0032] Example:

[0033] Please combine Figure 1-5 , a concrete structure pre-embedded flatness correction device of this embodiment includes:

[0034] Base 1, both sides of the top of the base 1 are rotatably connected with a bidirectional screw rod 2, and both sides of the outside of the bidirectional screw rod 2 are threadedly connected to a moving block 3, the top of the base 1 is symmetrically connected to a movable plate 4, and the movable plate 4 and the two groups of moving blocks 3 on the same side are hinged with a first connecting rod 5 through a hinge. A splint 6 is provided on one side of the movable plate 4, and a cross bar 7 is symmetrically fixedly connected to one side of the splint 6, and the cross bar 7 is slidably connected to the movable plate 4. The outer sleeve of the cross bar 7 is provided with a spring 8, and the two ends of the spring 8 are respectively fixedly connected to the movable plate 4 and the splint 6. One end of the two groups of bidirectional screw rods 2 are coaxially fixedly connected There is a transmission gear, and the two sets of transmission gears are connected by a transmission toothed belt 15. The other end of the bidirectional screw rod 2 on one side is coaxially fixedly connected to a handwheel, which is convenient for driving the two sets of bidirectional screw rods 2 to rotate in the same direction at the same time. The bottom of the movable plate 4 is symmetrically fixedly connected with a guide block. The top of the base 1 is provided with a guide groove at the position corresponding to the guide block and is slidably connected to the guide block, which can play a certain guiding role in the horizontal movement of the movable plate 4. The opposite surfaces of the two sets of plywood 6 are provided with anti-slip pads, which can increase the friction between the plywood 6 and the embedded parts, thereby improving the clamping and fixing effect of the embedded parts.

[0035] Two sets of vertical plates 9, two sets of vertical plates 9 are fixedly connected to the top of the two sets of movable plates 4, and the opposite surfaces of the two sets of vertical plates 9 are provided with T-shaped slide grooves 17. The internal equidistant sliding connection of the T-shaped slide grooves 17 is provided with T-shaped sliders 10. A pressure plate 11 is equidistantly provided between the two sets of vertical plates 9. On the same horizontal line, the two sets of T-shaped sliders 10 and the pressure plate 11 are symmetrically hinged with a second connecting rod 12 through a hinge. A through slot 16 is equidistantly provided on the pressure plate 11, and the same adjustment plate is inserted into the through slot 16 on the same vertical line. 13. The bottom of the adjusting plate 13 is fixedly connected with a pressing block 14 at equal intervals. The length of the T-shaped slide 17 is consistent with the length of the vertical plate 9. The length of the through groove 16 is greater than the length of the adjusting plate 13, which is convenient for the adjusting plate 13 to move inside the through groove 16. The height of the through groove 16 is consistent with the thickness of the adjusting plate 13. The bottom of the pressing block 14 is on the same horizontal plane as the bottom of the pressing plate 11, so that both the pressing plate 11 and the pressing block 14 can effectively press down the embedded parts.

[0036] The implementation principle of a concrete structure embedded flatness correction device in the embodiment of the present application is as follows: first, the embedded part is placed on the base 1, and then the two groups of T-shaped sliders 10 hinged to the pressure plate 11 by the second connecting rod 12 are respectively inserted into the two groups of T-shaped slide grooves 17, and then the T-shaped slider 10 is slid according to the welding position to adjust the position of the pressure plate 11, and then the position of the pressure block 14 is adjusted by sliding cooperation between the through groove 16 and the adjustment plate 13. Then, the hand wheel is turned, and the transmission cooperation between the transmission gear and the transmission toothed belt 15 is used to drive the two groups of bidirectional screw rods 2 to rotate in the same direction at the same time. The rotation of the bidirectional screw rod 2 will drive the two groups of movable blocks 3 threadedly connected thereto to move toward each other, and the hinge effect between the movable block 3 and the movable plate 4 and the first connecting rod 5, and the sliding cooperation between the guide block and the guide groove, so that the two groups of movable plates 4 can be pushed to move horizontally toward each other, thereby pushing the two groups of clamping plates 6 to approach the embedded part and clamp it, which not only improves the stability during welding of the embedded part, but also The two sets of vertical plates 9 move toward each other, and the two sets of vertical plates 9 move toward each other, which in turn drives the T-shaped sliders 10 on both sides to move toward each other. The hinged action between the T-shaped sliders 10 and the pressure plate 11 and the second connecting rod 12 can simultaneously drive the pressure plate 11 and the pressure block 14 to press down and fix the embedded parts, thereby improving the fixing efficiency of the embedded parts. When the splint 6 contacts the embedded parts, due to the continued movement of the movable plate 4 and the sliding cooperation between the movable plate 4 and the cross bar 7, the movable plate 4 will compress the spring 8, thereby playing a certain buffering role so that the pressure plate 11 continues to move down until it is pressed on the surface of the embedded parts, and finally the embedded parts are welded. When the welding is completed, the embedded parts are released, and the T-shaped slider 10 is slid out of the T-shaped slot 17 to remove the pressure plate 11 and the pressure block 14 at the same time, and the welded embedded parts can be removed.

[0037] In addition, a further improvement is that the end of the cross bar 7 is fixedly connected to a limit plate, which can prevent the cross bar 7 from being separated from the movable plate 4.
