Description

Technical Field

[0001] The invention relates to the technical field of post-cast strip supporting equipment, in particular to an adjustable independent supporting equipment for a post-cast strip. Background Art

[0002] Post-cast joints are concrete strips placed in corresponding locations on foundation slabs, walls, and beams during construction to prevent harmful cracks caused by uneven shrinkage or settlement of reinforced concrete structures. These strips are designed according to design or construction specifications to prevent harmful cracks. Post-cast joints temporarily divide the structure into several sections. After a period of time, after the internal shrinkage of the components, concrete is poured across the construction joints to connect the structure as a whole. Post-cast joints should be poured during cooler temperatures. Cement or concrete with a trace amount of aluminum powder added to cement should be poured. Its strength grade should be one level higher than that of the component to prevent cracks between the new and old concrete, creating weak spots. Common widths for post-cast joints are 800mm, 1000mm, and 1200mm.

[0003] Existing post-cast strip support equipment often uses scaffolding to directly support the bottom of the post-cast strip formwork. The width of the post-cast strip is adjusted by changing the width of the formwork placed on the scaffolding. This adjustment method is cumbersome and requires precise cutting of the formwork width. The operation is time-consuming and labor-intensive, making it difficult to quickly adjust and switch the width of common post-cast strips. At the same time, the process of setting up the bottom scaffolding also consumes a lot of manpower, and the subsequent removal is also not convenient, which reduces construction efficiency. To this end, we propose an adjustable independent support device for post-cast strips. Summary of the Invention

[0015] Compared with the prior art, the present invention has the following beneficial effects:

[0016] 1. The present invention provides an adjustable independent support device for the post-casting strip, which solves the problem that the existing post-casting strip support device is difficult to quickly and accurately switch the width of the post-casting strip when in use, affecting the construction efficiency. First, the base is pushed to the lower layer where the post-casting strip needs to be laid, and the operating shaft on one side is rotated to make the second bevel gear drive the first bevel gear, thereby making the threaded rod rotate, driving the lifting rod and the lifting frame to gradually move upward, so that the fixed plate and the fixed platform can be moved upward together, and the first template, the second template and the third template are lifted together until the top surface of the first template is flush with the bottom surface of the post-casting strip, and the overall height adjustment of the device can be completed.

[0017] 2. The present invention provides an adjustable independent support device for a post-cast strip. When the width of the post-cast strip needs to be widened, the operating shaft on the other side is rotated to make the control rod drive the rotating tube to rotate, so that the threaded groove drives the push plate to move downward, and the push plate pulls the first spring while gradually reducing the tension on the elastic pull rope. At this time, the connecting rod is plugged into the connecting groove, so that when the rotating tube rotates, it drives the connecting rod and the worm to rotate together, so that the threaded tube pushes the side plate and the first template to open synchronously to both sides, and at the same time, the upper end of the pushing rod tends to tilt upward. When the spacing between the two groups of first templates is exactly 200mm, the second template and the third template move up at the same time under the push of the pushing rod, and the bevel tooth block is ejected by the elastic force of the second spring to block and limit the bottom surface of the limit block on both sides of the second template, thereby completing the first section adjustment of the width of the post-cast strip.

[0018] 3. The present invention provides an adjustable independent support device for the post-casting strip. If it is necessary to further expand the width of the post-casting strip, continue to rotate the operating shaft so that the first template drives the second template to slide to both sides through the limit groove and the limit block, and the bottom surface of the third template is supported by the push rod and the sliding block. When the gap between the second templates on both sides is exactly equal to 200mm, the third template is pushed into the position between the two groups of second templates, and the bevel tooth block supports the bottom surface of the third template to complete the second section of adjustment. At this time, the top surfaces of the first template, the second template and the third template are flush, ensuring that the bottom surface is stably supported during the subsequent pouring of the post-casting strip, and the side plates on both sides limit the two sides of the post-casting strip.

[0019] 4. The present invention provides an adjustable independent support device for the post-casting strip. By rotating the operating shaft, the threaded rod can be rotated in the opposite direction, driving the lifting frame to move down to the bottom to complete the contraction. Then, another set of operating shafts is rotated in the opposite direction to make the control rod rotate in the opposite direction. At this time, the reverse rotation of the rotating tube will not drive the worm to rotate together. First, the pushing plate is moved up, and the first spring is compressed, so that the mounting plate has an upward trend. At the same time, the elastic pull rope is pulled, so that the bevel gear block is pulled to release the support for the bottom surface of the limit block. Then, the third template slides down into the fixed platform, and the plug-in rod is plugged into the plug-in groove, so that the worm drives the worm wheel to rotate in the opposite direction, and the side plates on both sides are closed in the opposite direction together with the first template. When the two sets of second templates are just merged, they can be pulled downward by the elastic telescopic rods on both sides of the third template. The second template and the third template are quickly pulled down together to complete the storage process. BRIEF DESCRIPTION OF THE DRAWINGS

The top surface of the sliding block 29 is slidably connected to the bottom surface of the third template 6 in the horizontal direction. The mounting plate 26 is provided with a lifting member 30 for controlling the lifting state of the third template 6.

[0037] The lifting member 30 includes a first spring 31 fixedly mounted on the bottom surface of the mounting plate 26, the bottom surface of the first spring 31 is fixedly connected to a push plate 32, the rotating tube 18 passes through the push plate 32, and the outer wall of the rotating tube 18 is provided with a threaded groove 33 threadedly connected to the push plate 32, the lifting rod 11 passes through the push plate 32 and the mounting plate 26, and is slidably connected to the push plate 32 and the mounting plate 26 in the vertical direction, the inner wall of the bottom end of the rotating tube 18 is slidably connected to a control rod 34 in the vertical direction, and the fixed platform 21 is provided with a support member 35 for stably supporting the bottom surface of the third template 6 when the third template 6 rises.

[0038] The support member 35 includes two groups of bevel gear blocks 36 that are slidably connected to the fixed platform 21 in the horizontal direction. The two groups of bevel gear blocks 36 are respectively located on both sides of the third template 6. One side of the bevel gear block 36 is fixedly connected to a second spring 37 that is fixedly connected to the fixed platform 21. An elastic pull rope 38 is fixedly connected to the bevel gear block 36. The end of the elastic pull rope 38 away from the bevel gear block 36 is fixedly connected to the bottom surface of the push plate 32. The control member 20 includes a connecting rod 39 that is rotatably connected to the bottom surface of the third template 6. The connecting rod 39 passes through the worm 19 and is slidably connected to the worm 19 in the vertical direction. The upper end of the rotating tube 18 is provided with a connecting groove 40 that is vertically connected to the connecting rod 39.

[0039] The lifting mechanism 9 also includes a threaded rod 41 rotatably connected to the base 1, the threaded rod 41 is threadedly connected to the inner wall of the bottom end of the lifting rod 11, a scale groove 42 is opened on the side of the lifting frame 10, and the support frame 3 is provided with a rotating member 43 for driving the control rod 34 and the threaded rod 41 to rotate. The rotating member 43 includes two groups of first bevel gears 44 coaxially fixedly connected to the control rod 34 and the bottom end of the threaded rod 41 respectively. The bottom surface of the first bevel gear 44 is rotatably connected to the base 1, and two groups of operating shafts 45 are rotatably connected to the support frame 3. The two groups of operating shafts 45 are coaxially fixedly connected to second bevel gears 46 that mesh with the two groups of first bevel gears 44 respectively.

[0040] First, push the base 1 to the lower layer where the post-casting strip needs to be laid, rotate the operating shaft 45 on one side so that the second bevel gear 46 drives the first bevel gear 44, thereby rotating the threaded rod 41, driving the lifting rod 11 and the lifting frame 10 to gradually move up, so that the fixed plate 12 and the fixed platform 21 can be moved up together, and the first template 2, the second template 5 and the third template 6 are lifted together until the top surface of the first template 2 is flush with the bottom surface of the post-casting strip, and the overall height adjustment of the device can be completed. During the adjustment process, the rotating tube 18 will slide in the vertical direction on the outer wall of the control rod 34, and always maintain contact with the control rod 34. The connection between the rods 34 is made. Since the width of the post-cast strip is generally 800mm, 1000mm, and 1200mm, by setting the width of the two groups of first templates 2 to 400mm, the width of the two groups of second templates 5 to 100mm, and the width of the third template 6 to 200mm, when the second template 5 is below the first template 2, the two groups of first templates 2 just form a post-cast strip with a width of 800mm. When the second template 5 moves up and docks with the first template 2, the width is 1000mm. When the third template 6 docks with the second template 5, the width of the post-cast strip is 1200mm.

[0041] When the width of the post-casting strip needs to be widened, the control rod 34 drives the rotating tube 18 to rotate by rotating the operating shaft 45 on the other side, so that the threaded groove 33 drives the pushing plate 32 to move downward, and the pushing plate 32 pulls the first spring 31 while gradually reducing the tension on the elastic pull rope 38. At this time, since the third template 6 is in the lower position, the plug-in rod 39 is plugged into the plug-in groove 40, so that when the rotating tube 18 rotates, the plug-in rod 39 and the worm 19 are driven to rotate together, and the worm 19 drives the worm gear 16 to rotate, and the worm gear 16 drives the driving rods 17 on both sides to rotate, and the driving rod 17 drives the threaded tube 14 to rotate, so that the threaded tube 14 can push the side plates 13 and The first templates 2 are opened synchronously to both sides, and at the same time, the mounting plate 26 is pulled downward by the first spring 31, so that the upper end of the push rod 27 tends to tilt upward. When the spacing between the two groups of first templates 2 is exactly 200 mm, the second template 5 and the third template 6 are pushed up at the same time by the push rod 27, and the two groups of second templates 5 are inserted into the gap between the two groups of first templates 2 at the same time. The limit block 22 on the second template 5 is inserted into the limit groove 23 on the first template 2, and the bevel tooth block 36 is popped out by the elastic force of the second spring 37, blocking and limiting the bottom surface of the limit block 22 on both sides of the second template 5, thereby completing the first section adjustment of the width of the post-casting strip.

[0042] If it is necessary to further expand the width of the post-cast strip, continue to rotate the operating shaft 45 so that the first template 2 drives the second template 5 to slide to both sides through the limit groove 23 and the limit block 22. The rotating shafts 24 on both sides of the second template 5 will pull the elastic telescopic rod 25 so that the third template 6 has a tendency to pull up. At the same time, the bottom surface of the third template 6 is supported by the push rod 27 and the sliding block 29. When the gap between the second templates 5 on both sides is exactly equal to 200mm, the third template 6 is pushed into the position between the two groups of second templates 5, and the bevel tooth block 36 supports the bottom surface of the third template 6 to complete the second section of adjustment. At this time, the top surfaces of the first template 2, the second template 5 and the third template 6 are flush, ensuring that the bottom surface is stably supported during the subsequent casting of the post-cast strip, and the side panels 13 on both sides limit the two sides of the post-cast strip.

[0043] After use, the threaded rod 41 can be rotated in the opposite direction by rotating the operating shaft 45, driving the lifting frame 10 to move down to the bottom and complete the retraction, and then the other set of operating shafts 45 are rotated in the opposite direction to rotate the control rod 34 in the opposite direction. Since the third template 6 will drive the connecting rod 39 to move up and release the connection with the connecting groove 40 when it moves up, the reverse rotation of the rotating tube 18 will not drive the worm 19 to rotate together, avoiding the situation where the third template 6 is directly clamped and stuck. At this time, the pushing plate 32 will be moved up first, compressing the first spring 31, so that the mounting plate 26 has a tendency to move up, and at the same time, the elastic pull rope 38 is pulled, so that the bevel gear block 36 is pulled to release the support on the bottom surface of the limit block 22, and then the third template 6 slides down to the fixed position. In the fixed platform 21, the connecting rod 39 is connected with the connecting groove 40, so that the worm 19 drives the worm wheel 16 to rotate in the opposite direction, and the side panels 13 on both sides are closed in the opposite direction with the first template 2. At this time, the push plate 32 continues to move upward, and the downward pulling force of the third template 6 increases. At the same time, the elastic telescopic rods 25 on both sides apply a downward pulling force to the second template 5. When the two groups of second templates 5 are just merged, they can be pulled downward by the elastic telescopic rods 25 on both sides of the third template 6, and the second template 5 and the third template 6 are quickly pulled down together. Since the movement speed of the first template 2 is relatively slow when opening and closing, the rotation speed of the operating shaft 45 can be slowed down during the insertion and removal of the second template 5 and the third template 6 to avoid jamming.

[0044] It is worth noting that an alarm (not shown) may be provided at the connection position of the first template 2 and the second template 5, which is used to sound an alarm when the spacing is about to open or close and reaches 200mm, reminding people to slow down the rotation speed. After the second template 5 moves down, continue to rotate the operating shaft 45 so that the first templates 2 on both sides continue to be close together to complete the storage process. When only the second template 5 is flush with the first template 2 and the width of the post-pouring strip is 1000mm, after use, it is necessary to first adjust the width to 1200mm, and then rotate the operating shaft 45 in the opposite direction to retract it. By observing the corresponding state of the upper end position of the support frame 3 and the scale groove 42 on the lifting frame 10, the overall height state of the lifting frame 10 can be judged.
