Description

Technical Field

[0001] This application relates to the field of concrete construction, and more particularly to a concrete structure formwork frame. Background Technology

[0002] Concrete structure formwork frames are supporting structural systems used for concrete pouring in building construction. They ensure the quality of concrete structure forming. During the concrete pouring process, the formwork frame acts as a temporary structure, capable of bearing the weight of the concrete and construction loads, providing necessary support for building construction, and maintaining the shape and position of the building structure. The concrete protective layer is the concrete layer from the outer edge of the reinforcing steel bars in the structural member to the surface of the member, which plays a role in protecting the reinforcing steel bars and preventing them from being directly exposed.

[0003] However, in the process of implementing the relevant technical solutions, at least the following technical problems were found: When determining the thickness of the protective layer in concrete structure formwork, square steel with the same thickness as the set protective layer is generally used and placed on the outside of the reinforcing bars. However, when conducting quality control of the protective layer of large-span concrete structures, it is necessary to prepare square steel with different thicknesses and lengths according to the thickness of different protective layers, which is inconvenient to use. Utility Model Content

[0004] This application provides a concrete structure formwork frame, which solves the problem of inconvenient control of the protective layer quality of large-span concrete formwork in the prior art, and realizes the effect of changing the thickness of the protective layer control component according to the protective layer size.

[0005] This application provides a concrete structure formwork frame, including a concrete formwork with two rows of reinforcing bars inside. Multiple protective layer control components are provided on both sides of the top of the inner wall of the concrete formwork, positioned between the inner wall of the concrete formwork and the reinforcing bars. Each protective layer control component includes: a fixed seat located at the top of the inner wall of the concrete formwork, with the fixed seats detachably connected end-to-end; a movable seat located on the side of the fixed seat near the reinforcing bars, and in contact with the reinforcing bars; and multiple movable components located inside the fixed seats, used to move the movable seat.

[0006] Furthermore, a slot is provided on one side of the fixing base, and a block is provided on the other side of the fixing base, the block matching the slot.

[0007] Furthermore, the plurality of moving components include: a lead screw, rotatably connected to the interior of the fixed seat, and the plurality of lead screws are arranged parallel to each other at equal intervals inside the fixed seat; a movable rod, sleeved and threadedly connected to the outside of the lead screw, and one end of the movable rod passes through the fixed seat and is fixedly connected to the moving seat.

[0008] Furthermore, limit blocks are fixedly provided on both sides of the movable rod, and the movable rod and the two limit blocks are interlocked with the fixed base.

[0009] Furthermore, one of the lead screws on the side is provided with a synchronous drive assembly, which includes: a rotating shaft rotatably connected to the side of the lead screw; a knob rotatably connected to the top of the fixed base and fixedly connected to the rotating shaft; a worm gear fixedly disposed on the outside of the rotating shaft; and a worm wheel fixedly disposed on the outside of one of the lead screws on the side, the worm wheel meshing with the worm gear.

[0010] Furthermore, the synchronous drive assembly includes: a driving gear, fixedly disposed at one end of one of the lead screws on the side; and a driven gear, fixedly disposed at one end of the remaining lead screws. The driving gear meshes with the adjacent driven gear, and the two adjacent driven gears mesh with each other.

Detailed Implementation

[0019] This application discloses a concrete structure formwork frame. The worm gear 343 drives the worm wheel 344 and the lead screw 331 to rotate. With the meshing between the driving gear 345 and the driven gear 346, multiple lead screws 331 can synchronously drive the threaded movable rod 332 to move accordingly. This changes the overall thickness of the fixed seat 31 and the movable seat 32 to adapt to the size of the protective layer, improving the flexibility of use. Moreover, the multi-segment fixed seat 31 can be easily assembled together to meet the needs of large-span formwork frames.

[0020] To better understand the above technical solutions, the following will provide a detailed explanation of the technical solutions in conjunction with the accompanying drawings and specific implementation methods.

[0021] Please refer to Figure 1 and Figure 2This embodiment provides a concrete structure formwork frame, including a concrete formwork 10. Two rows of reinforcing bars 20 are arranged inside the concrete formwork 10. Multiple protective layer control components 30 are provided on both sides of the top of the inner wall of the concrete formwork 10. These multiple protective layer control components 30 are disposed between the inner wall of the concrete formwork 10 and the reinforcing bars 20. Each protective layer control component 30 includes a fixed base 31, a movable base 32, a moving component 33, and a synchronous drive component 34. The fixed base 31 is located at the top of the inner wall of the concrete formwork 10, and the multiple fixed bases 31 are detachably connected end-to-end. A slot is provided on one side of the fixed base 31, and a locking block is provided on the other side of the fixed base 31. The locking block matches the slot. The movable base 32 is located on the side of the fixed base 31 closest to the reinforcing bars 20, and the movable base 32 is in contact with and connected to the reinforcing bars 20. Multiple movable components 33 are disposed inside the fixed base 31, and the multiple movable components 33 are used to drive the movable base 32 to move. The movable components 33 can be electric push rods. The movable components 33 drive the movable base 32 to move on one side of the fixed base 31, so that the distance between the movable base 32 and the fixed base 31 changes. Thus, according to the required size of the protective layer of the concrete formwork 10, the overall thickness of the protective layer control component 30 is changed. Through the cooperation of the locking block on the fixed base 31 and the locking groove on the adjacent fixed base 31, multiple fixed bases 31 can be installed together to determine the protective layer of the large-span concrete formwork 10, ensuring the line shape of the concrete structure. When the length of the concrete formwork 10 does not match the overall length of the multiple fixed bases 31, shorter shims or square steel can be added to determine the thickness of the protective layer.

[0022] Please refer to Figure 1 , Figure 2 and Figure 3 Multiple movable components 33 include a lead screw 331, a movable rod 332, and a limiting block 333. The lead screw 331 is rotatably connected to the inside of the fixed base 31, and the multiple lead screws 331 are arranged parallel to each other at equal intervals inside the fixed base 31. The movable rod 332 is sleeved and threaded to the outside of the lead screw 331, and one end of the movable rod 332 passes through the fixed base 31 and is fixedly connected to the movable base 32. Two limiting blocks 333 are disposed on both sides of the movable rod 332, and the movable rod 332 and the two limiting blocks 333 are inserted and connected to the fixed base 31. A synchronous drive assembly 34 for driving the rotation of multiple lead screws 331 is disposed on one side of one of the lead screws 331. The rotation of the multiple lead screws 331 drives the movable rod 332 threadedly connected to the lead screw 331 to move accordingly. The limit block 333 limits the movement of the movable rod 332 to prevent the movable rod 332 from rotating with the lead screw 331, so that the movable rod 332 can extend outward to drive the moving seat 32 to move, thereby changing the overall thickness of the fixed seat 31 and the moving seat 32 to adapt to the determination of different thickness protective layers.

[0023] Please refer to Figures 1-4The synchronous drive assembly 34 includes a rotating shaft 341, a knob 342, a worm gear 343, a worm wheel 344, a driving gear 345, and a driven gear 346. The rotating shaft 341 is rotatably connected to the side of the lead screw 331. The knob 342 is rotatably connected to the top of the fixed base 31 and is fixedly connected to the rotating shaft 341. A rotation scale is provided around the rotating shaft 341 on the top of the fixed base 31, and a scale needle is provided on the rotating shaft 341. The worm gear 343 is fixedly installed on the outside of the rotating shaft 341, and the worm wheel 344 is fixedly installed on the outside of one of the lead screws 331 on the side. The worm wheel 344 meshes with the worm gear 343. The rotation of the rotating shaft 341 is driven by the knob 342, which causes the worm gear 343 on the outside of the rotating shaft 341 to rotate accordingly, driving the driven gear 346. The lead screw 331 rotates, thereby adjusting the position of the movable seat 32. The rotation scale set on the top of the fixed seat 31 corresponds to the overall thickness of the fixed seat 31 and the movable seat 32. When the knob 342 rotates to change the overall thickness of the fixed seat 31 and the movable seat 32, the knobs 342 on the other fixed seats 31 rotate to the same scale position, which can ensure that the overall thickness of the fixed seat 31 and the movable seat 32 is consistent, ensuring the linearity of the concrete structure and allowing for precise control of the thickness of the protective layer. This prevents problems such as inconsistent concrete structure dimensions and uneven protective layer thickness. The self-locking between the worm 343 and the worm wheel 344 can also prevent the thickness of the fixed seat 31 and the movable seat 32 from changing due to external forces, ensuring the overall strength of the fixed seat 31 and the movable seat 32.

[0024] Please refer to Figures 1-4 A driving gear 345 is fixedly mounted on one end of one of the lead screws 331 on the side, and a driven gear 346 is fixedly mounted on one end of the remaining lead screws 331. The driving gear 345 meshes with the adjacent driven gear 346, and two adjacent driven gears 346 mesh with each other. The worm wheel 344, which meshes with the worm 343, drives one lead screw 331 to rotate. The rotation of one lead screw 331 causes the driving gear 345 to rotate, which in turn drives the adjacent driven gear 346 that it meshes with to rotate. The driven gear 346 then drives the other adjacent driven gear 346 to rotate. The driven gear 346 rotates, causing the driving gear 345 and multiple driven gears 346 to rotate synchronously, which in turn causes multiple lead screws 331 to rotate synchronously. This causes the movable rod 332, which is threaded to it, to move outward synchronously. Since the rotation directions of two adjacent lead screws 331 are opposite, in order to ensure that the movable rod 332 moves synchronously, the threads of adjacent lead screws 331 must be aligned in opposite directions. This allows multiple movable rods 332 to drive the movable seat 32 to move outward synchronously. This multi-point synchronous movement of the movable seat 32 ensures that the movable seat 32 remains flat during movement, thereby ensuring a more accurate and uniform protective layer.

[0025] The functional principle of this application can be explained through the following methods:

[0026] In use, select an appropriate number of fixing seats 31 according to the overall length of the concrete formwork 10. When the length of the concrete formwork 10 does not match the overall length of the multiple fixing seats 31, shorter shims or square steel can be added to determine the protective layer thickness. Insert the locking block of the fixing seat 31 into the locking groove of another fixing seat 31 so that the multiple fixing seats 31 can be connected end to end, and then install them on the outside of the concrete formwork 10. Determine the scale position to which the knob 342 and the rotating shaft 341 need to be rotated according to the required thickness of the protective layer. Rotate the knob 342 to rotate it to the designated position. The rotation of the knob 342 drives the worm gear 343 on the outside of the rotating shaft 341 to rotate, so that the worm wheel 344 meshing with the worm gear 343 drives the inner lead screw 331 to rotate. The rotation of one lead screw 331 drives the driving gear 345 at one end to rotate, so that the driving gear 345 drives the driven gear 346 meshing with it on one side to rotate. The driven gear 346 The rotation drives the adjacent meshing driven gears 346 to rotate, so that the driving gear 345 and multiple driven gears 346 can drive multiple lead screws 331 to rotate synchronously. The rotation of multiple lead screws 331 drives the movable rod 332, which is threaded to it on the outside, to move outward. This causes the movable rod 332 to move the movable seat 32 outward, thereby changing the overall thickness of the fixed seat 31 and the movable seat 32 to adapt to the protective layer with different thickness requirements. The two limiting blocks 333 on the outside of the movable rod 332 limit the movement of the movable rod 332 to prevent the movable rod 332 from rotating with the lead screw 331. The self-locking of the worm 343 and the worm wheel 344 also prevents the thickness of the fixed seat 31 and the movable seat 32 from changing due to external forces, so that the thickness of the protective layer can remain unchanged. By rotating the knobs 342 on the top of multiple fixed seats 31 to the appropriate scale position in sequence, the thickness of multiple fixed seats 31 and the movable seat 32 is kept consistent, making the thickness of the protective layer more accurate and uniform.
