Description

Technical Field

[0001] This utility model relates to the field of steel reinforcement technology, specifically to a prefabricated floor slab steel reinforcement device. Background Technology

[0002] Prefabricated reinforced concrete floor slabs are made in a prefabrication yard and then installed on the construction site. The commonly used types of prefabricated reinforced concrete slabs can be divided into three types according to their cross-sectional shape: flat slabs, channel slabs, and hollow slabs. Reinforcement work is required when making prefabricated floor slabs.

[0003] For example, a reinforcement device for internal steel bars in a reinforced concrete protective door, with announcement number "CN220741638U," facilitates the movement of support blocks and allows for adjustment of the distance between support blocks according to the length of the reinforcement bars, improving practicality. The moving fixing plate facilitates the fixation of the reinforcement bars inside the fixing assembly. However, adjusting the distance between the support blocks requires workers to pull out the second pins on both sides from the support blocks, then move the support blocks on both sides separately, and then insert the second pins again. This process is cumbersome, requiring workers to walk around the device multiple times, resulting in low working efficiency. Utility Model Content

[0004] The purpose of this utility model is to solve the problem that adjusting the distance between support blocks is a complicated process with low device efficiency, and therefore proposes a prefabricated floor slab steel reinforcement device.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] Design a prefabricated floor slab reinforcement device, including a support frame and a curved plate. The outer wall of the support frame is slidably connected to the curved plate. A box is fixedly connected to the upper end of the curved plate. The box has a position adjustment structure inside. Two straight plates are fixedly connected to the ends of the box and are slidably connected to pins.

[0007] Preferably, the position adjustment structure includes a handle, a straight rod fixedly connected to the end of the handle, the outer wall of the straight rod slidably connected to a circular plate, a spring sleeved on the outer wall of the straight rod, the two ends of the spring being fixedly connected to the handle and the circular plate respectively, the end of the straight rod abutting against the housing, the circular plate being fixedly connected to one end of the rotating shaft of the first bevel gear, the two ends of the rotating shaft of the first bevel gear being rotatably connected to the housing through bearings, the first bevel gear meshing with two second bevel gears, and a threaded rod fixedly connected to the end of the second bevel gear.

[0008] Preferably, the two ends of the threaded rod are rotatably connected to the vertical plate and the box body respectively through bearings, and the vertical plate is fixedly connected to the inner wall of the box body.

[0009] Preferably, the threaded rod is threadedly connected to the support block, and the end of the support block is slidably connected to the housing.

[0010] Preferably, the support frame has multiple insertion holes machined inside, and the pin is inserted into the insertion holes.

[0011] The present invention proposes a prefabricated floor slab reinforcement device, the advantages of which are as follows: Through the coordination of the position adjustment structure and the operator, the operator pulls the handle, the movement of the handle drives the straight rod to move, pulling the straight rod out from the box. Then, the operator rotates the handle to drive the straight rod to rotate, the rotation of the straight rod drives the circular plate to rotate, the rotation of the circular plate drives the first bevel gear to rotate, the rotation of the first bevel gear drives the two second bevel gears to rotate, and the rotation of the two second bevel gears drives the threaded rod to rotate. The thread direction of the two threaded rods is the same, but the rotation direction is opposite. Therefore, the rotation of the two threaded rods can drive the support blocks on both sides to move closer or further apart. According to actual needs, the distance between the two support blocks can be adjusted at one time, improving the working efficiency of the device. Attached Figure Description

[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] See attached document Figure 1-6 :

[0021] In this embodiment, a prefabricated floor slab reinforcement device includes a support frame 1 and a curved plate 2. The outer wall of the support frame 1 is slidably connected to the curved plate 2. A box 3 is fixedly connected to the upper end of the curved plate 2. A position adjustment structure 4 is provided inside the box 3. Two straight plates 6 are fixedly connected to the end of the box 3. The straight plates 6 are slidably connected to pins 7. Multiple insertion holes 8 are machined inside the support frame 1. The pins 7 are inserted into the insertion holes 8. The pins 7 can limit the position of the straight plates 6, thereby limiting the position of the box 3.

[0022] See attached document Figure 1-6 :

[0023] The position adjustment structure 4 includes a handle 401, with a straight rod 402 fixedly connected to the end of the handle 401. The outer wall of the straight rod 402 is slidably connected to a circular plate 403. A spring 404 is sleeved on the outer wall of the straight rod 402. The spring force coefficient of the spring 404 is selected according to the actual working requirements to meet the working needs. The two ends of the spring 404 are fixedly connected to the handle 401 and the circular plate 403 respectively. The end of the straight rod 402 is pressed against the housing 3. Pulling the handle 401 can pull the straight rod 402 out of the housing 3. Then, rotating the handle 401 can drive the straight rod 402 to rotate. The rotation of the straight rod 402 can drive the circular plate 403 to rotate. The circular plate 403 is fixedly connected to one end of the rotating shaft of the first bevel gear 405. The two ends of the rotating shaft of the first bevel gear 405 are rotatably connected to the housing 3 through bearings. The rotation of the circular plate 403 can drive the first bevel gear 405 to rotate.

[0024] The first bevel gear 405 is meshed with two second bevel gears 406. The ends of the second bevel gears 406 are fixedly connected to threaded rods 407. The two ends of the threaded rods 407 are rotatably connected to the vertical plate 9 and the housing 3 respectively through bearings. The vertical plate 9 is fixedly connected to the inner wall of the housing 3. The rotation of the first bevel gear 405 can drive the second bevel gears 406 to rotate, and at the same time drive the threaded rods 407 to rotate. The threaded rods 407 are threadedly connected to the support block 5. The end of the support block 5 is slidably connected to the housing 3. The rotation of the threaded rods 407 can drive the support block 5 to move.

[0025] Working principle:

[0026] First, the workers align the bent plate 2 with the sliding grooves on both sides of the support frame 1, insert the bent plate 2 into the support frame 1, and then adjust the distance between the two boxes 3 according to the length of the steel bar. After adjusting the distance between the two boxes 3, the pin 7 is inserted into the hole 8 through the straight plate 6 to fix the position of the box 3.

[0027] Adjustment of the distance between the support blocks:

[0028] Pulling handle 401 moves the straight rod 402, pulling it out of the housing 3. Then, rotating handle 401 rotates the straight rod 402, causing the circular plate 403 to rotate. The circular plate 403 then rotates the first bevel gear 405, which in turn rotates the two second bevel gears 406 in opposite directions. The rotation of the second bevel gears 406 then rotates the threaded rod 407, whose threads are in the same direction but opposite in rotation. Therefore, the rotation of the two threaded rods 407 can move the support blocks 5 on both sides closer together or further apart. Adjust the distance between the two support blocks 5 according to actual needs. After adjustment, the straight rod 402 aligns with the slot. Releasing handle 401 allows the spring 404 to press the straight rod 402 firmly against the housing 3, preventing the support blocks 5 from moving.

[0029] After adjusting the distance between the support blocks 5, the workers used the support blocks 5 as a reference to adjust the position of the steel bar mold so that it was placed at the two support blocks 5. Finally, the steel bars were assembled into the mold to facilitate the subsequent fabrication of the prefabricated floor slab and complete the steel bar reinforcement work for the prefabricated floor slab.

[0030] Although the present invention has been illustrated and described with reference to preferred embodiments, those skilled in the art should understand that various changes in form and detail are possible within the scope of the claims.
