Description

Technical Field

[0001] This application relates to the field of building construction technology, and in particular to a height-adjustable steel formwork. Background Technology

[0002] In the construction process, steel formwork serves as a crucial tool for concrete pouring, and its height adjustment is essential to adapt to different construction needs. Traditional steel formwork typically has a fixed height and cannot be flexibly adjusted, which significantly limits construction efficiency and quality. To meet different height requirements, construction workers often need to replace steel formwork of different specifications, which not only increases construction costs but also reduces work efficiency. Therefore, developing a height-adjustable steel formwork has become an urgent need in the construction industry. Summary of the Invention

[0003] The purpose of this application is to provide a height-adjustable steel mold that can adapt to different height requirements and improve the versatility of the steel mold.

[0004] Firstly, the height-adjustable steel mold provided in this application adopts the following technical solution:

[0005] A height-adjustable steel mold, comprising:

[0006] First frame;

[0007] The second frame, spaced apart from the first frame, includes a fixed plate and multiple ribs. The multiple ribs are detachably connected to the fixed plate, and the ribs have sliding grooves along their own length.

[0008] A telescopic assembly is disposed between the first frame and the second frame and can extend into the slide groove. The telescopic assembly includes multiple movable plates that are movably connected to adjacent movable plates.

[0009] The first frame is connected to a plurality of fixing rods, each of which corresponds to a plurality of ribs, and each of the fixing rods abuts against the back of the movable plate to fix the movable plate.

[0010] By adopting the above technical solution, the height of the steel mold can be adjusted by controlling the number of movable plates extending into the chute, thereby increasing the flexibility and versatility of the steel mold.

[0011] Optionally, adjacent movable plates are movably connected by a connector, the connector including a connecting plate and two fixed posts. The connecting plate is disposed between adjacent movable plates, and both ends are provided with connecting grooves along the length direction. The two connecting grooves are provided one-to-one with the two fixed posts.

[0012] The fixed post passes through the connecting groove and is detachably connected to the corresponding movable plate. The sliding groove and the fixed rod are offset in the lateral direction. When the movable plate is not inserted into the sliding groove, the top surface of the movable plate abuts against the rib plate, and the front surface of the movable plate is flush with the side of the fixed plate away from the rib plate.

[0013] By adopting the above technical solution and through the design of the connector, the movable plates that are not inserted into the slide groove can be tightly abutted end to end. Since the connecting plate has a connecting groove, the connecting plate can slide between the two movable plates. The movable plates that are inserted into the slide groove and the movable plates that are not inserted into the slide groove can also extend, so that the adjacent movable plates are fitted with a gap.

[0014] Optionally, the first frame is provided with a receiving groove, which is opened along the length direction of the fixing rod, and the fixing rod is slidably connected in the receiving groove.

[0015] By adopting the above technical solution, the receiving groove design on the first frame allows the fixing rod to slide in the length direction, which can prevent the fixing rod from obstructing the adjustment process when the height of the steel mold is adjusted, and can fix the movable plate after the adjustment is completed.

[0016] Optionally, pulleys are rotatably connected to both the receiving groove and the sliding groove. The sides of the fixed rod and the movable plate abut against the corresponding pulleys. When the fixed rod or the movable plate slides, it drives the corresponding pulleys to rotate.

[0017] By adopting the above technical solution, the addition of pulleys reduces the friction when the fixed rod and the movable plate slide, making the adjustment process smoother and improving the adjustment efficiency and service life.

[0018] Optionally, a cover plate is provided between the first frame and the second frame, the cover plate being rotatably connected to the second frame for opening or sealing the slide.

[0019] By adopting the above technical solution, when the steel mold is at its highest height, the cover plate can block the slide groove and prevent the movable plate from falling into the slide groove, thereby maintaining the height of the steel mold and ensuring its stability.

[0020] Optionally, limit holes are provided on both sides of the cover plate, and a limit block extends from one end of the fixing rod near the cover plate. When the cover plate blocks the slide groove, the fixing rod can abut against the cover plate, and the limit block extends into the limit block.

[0021] By adopting the above technical solution and setting limiting holes and limiting blocks, when the fixing rod abuts against the cover plate, the fixing rod and the cover plate are interlocked, thereby preventing the end of the fixing rod near the cover plate from bending and ensuring that the fixing rod can also fix the movable plate located at the lower position.

[0022] Optionally, a plug-in rod is detachably connected to the fixing rod. The plug-in rod and the fixing rod are spaced apart in the lateral direction. A plug-in hole is provided on the movable plate. When the fixing rod abuts against the cover plate, the plug-in rod is inserted into the plug-in hole.

[0023] By adopting the above technical solution, the plug-in rod and the movable plate are plugged together, so that the movable plate that has not been inserted into the slide groove can maintain a tight connection at both ends, preventing the possibility of the telescopic assembly disintegrating between the first frame and the second frame.

[0024] Optionally, locking pins are provided at both ends of the cover plate, and locking holes are provided on the rib plate. The locking pins pass through the locking holes and are detachably connected to the cover plate.

[0025] By adopting the above technical solution, when the cover plate seals the slide groove, the position of the cover plate is locked by the locking pin, preventing the cover plate from moving accidentally after sealing the slide groove.

[0026] Optionally, it may also include reinforcing ribs, which are detachably connected to the plurality of the fixing rods.

[0027] By adopting the above technical solution, the fixing rod's ability to fix the movable plate is enhanced.

[0028] In summary, this application includes at least one of the following beneficial technical effects:

[0029] 1. By controlling the number of movable plates extending into the chute, the height of the steel mold can be adjusted, increasing the flexibility and versatility of the steel mold. Through the design of the connecting parts, the movable plates that are not extended into the chute can be tightly connected end to end. Since the connecting plate has a connecting groove, the connecting plate can slide between two movable plates. The movable plates that are extended into the chute and those that are not extended into the chute can also extend, so that the adjacent movable plates are fitted with a clearance.

[0030] 2. The receiving groove design on the first frame allows the fixing rod to slide in the length direction, which can prevent the fixing rod from obstructing the adjustment process when the height of the steel mold is adjusted, and can fix the movable plate after the adjustment is completed.

[0031] 3. By setting limit holes and limit blocks, when the fixing rod abuts against the cover plate, the fixing rod and the cover plate are interlocked, thereby preventing the end of the fixing rod near the cover plate from bending and ensuring that the fixing rod can also fix the movable plate located at the lower position.

Detailed Implementation

[0038] The following is in conjunction with the appendix Figure 1 -Appendix Figure 5 This application will be described in further detail below.

[0039] A height-adjustable steel mold, as shown in the reference. Figure 1 and Figure 2 The system includes a first frame 1, a second frame 2, and a telescopic component 3. The first frame 1 and the second frame 2 are spaced apart in the vertical direction, while the telescopic component 3 is placed between the first frame 1 and the second frame 2 and can be partially or fully inserted into the second frame 2 to adjust the height of the steel mold.

[0040] Specifically, the second frame 2 includes a fixing plate 22 and multiple ribs 21. In the embodiment, the number of ribs 21 is preferably 5. The front of the fixing plate 22 serves as the forming surface during concrete pouring, while the multiple ribs 21 can be detachably connected to the back of the fixing plate 22 to enhance the overall strength of the second frame 2.

[0041] It should be noted that the first frame 1 and the second frame 2 have the same structure, which will not be elaborated on here.

[0042] Furthermore, combined Figure 3 Since the second frame 2 is placed on the bottom side when forming concrete, in order to make the steel mold more stable and upright in the construction area (i.e., the concrete pouring area), the side of the second frame 2 away from the first frame 1 is also provided with an arc-shaped frame plate 20. The frame plate 20 is smoothly connected to the fixing plate 22. In addition, multiple support plates 30 are provided between the frame plate 20 and the rib plate 21. The multiple support plates 30 are provided one-to-one with the multiple rib plates 21. One side of the support plate 30 is fixedly connected to the frame plate 20, and the other side of the support plate 30 is fixedly connected to the corresponding rib plate 21.

[0043] Furthermore, a groove 211 is provided on the rib plate 21 along its own length direction for the telescopic component 3 to extend into. The telescopic component 3 includes a plurality of movable plates 31. In this embodiment, the number of movable plates 31 is preferably three. Adjacent movable plates 31 are movably connected. Specifically, a connector 32 is provided between adjacent movable plates 31 to movably connect adjacent movable plates 31.

[0044] Specifically, refer to Figure 1 and Figure 2 The connector 32 includes a connecting plate 321 and two fixing posts 322. The connecting plate 321 is disposed between adjacent movable plates 31, and both ends are provided with connecting grooves 3211 along the length direction. The two connecting grooves 3211 are correspondingly provided with the two fixing posts 322. The fixing posts 322 pass through the connecting grooves 3211 and are detachably connected to the corresponding movable plates 31. The sliding groove 211 and the fixing rod 4 are offset in the lateral direction.

[0045] The connector 32 is designed so that the movable plates 31 that are not inserted into the slide groove 211 can be tightly abutted end to end, while the movable plates 31 that are inserted into the slide groove 211 and the movable plates 31 that are not inserted into the slide groove 211 can also extend (because the connecting plate 321 has a connecting groove 3211, the connecting plate 321 can slide between the two movable plates 31), so that the adjacent movable plates 31 are fitted with a clearance.

[0046] Combination Figure 4When the movable plate 31 is not inserted into the chute 211, the steel mold is at its highest height. The movable plate 31 at the lowest position abuts against the top surface of the rib plate 21, and the front of the movable plate 31 is flush with the side of the fixed plate 22 away from the rib plate 21, thus making the surface of the concrete smooth after it is poured. When some of the movable plates 31 are inserted into the chute 211, the movable plate 31 at the lowest position abuts against the top surface of the rib plate 21. When all the movable plates 31 are inserted into the chute 211, the steel mold is at its lowest height, and the first frame 1 abuts against the second frame 2.

[0047] Reference Figure 1 and Figure 2 The first frame 1 is connected to multiple fixing rods 4, which are respectively set to correspond to multiple ribs 21. The multiple fixing rods 4 abut against the back of the movable plate 31 to fix the movable plate 31. Correspondingly, the first frame 1 is provided with a receiving groove 11, which is opened along the length direction of the fixing rod 4. The fixing rod 4 is slidably connected in the receiving groove 11.

[0048] When adjusting the height of the steel mold, the fixing rod 4 extends out of the receiving groove 11 (i.e., it is in vertical clearance fit with the rib plate 21). After the height of the steel mold is adjusted, the fixing rod 4 is slid to abut against the rib plate 21, thereby fixing the movable plate 31 that has not extended into the sliding groove 211, preventing the movable plate 31 from being pushed laterally during concrete pouring.

[0049] Reference Figure 1 and Figure 3 It also includes reinforcing ribs 10, which are detachably connected to the portions of multiple fixing rods 4 extending out of the receiving grooves 11 to enhance the fixing ability of the fixing rods 4 to the movable plate 31. In addition, reinforcing ribs 10 are also provided on the first frame 1 and the second frame 2 to further strengthen the overall strength of the steel mold.

[0050] Furthermore, combined Figure 4 Both the receiving groove 11 and the sliding groove 211 are rotatably connected to pulleys 5. The sides of the fixed rod 4 and the movable plate 31 abut against the corresponding pulleys 5. When the fixed rod 4 or the movable plate 31 slides, it drives the corresponding pulleys 5 to rotate, so as to reduce the friction experienced by the fixed rod 4 when it slides in the receiving groove 11 and the movable plate 31 when it extends into the sliding groove 211.

[0051] In addition, a cover plate 6 is provided between the first frame 1 and the second frame 2. The cover plate 6 is rotatably connected to the side of the rib plate 21 away from the fixed plate 22. By rotating, it opens or seals the slide groove 211. Specifically, in Figure 1 At this time, the slide 211 is in the open state. Figure 4At this time, the chute 211 is in a blocked state.

[0052] It should be noted that in other embodiments, the cover plate 6 can also be slidably connected to the top surface of the rib plate 21. By sliding the cover plate 6 laterally, the slide groove 211 can also be opened or blocked. In this embodiment, when the slide groove 211 is blocked, the steel mold is at its highest height. The cover plate 6 prevents the movable plate 31 from falling into the slide groove 211, thereby maintaining the height of the steel mold and ensuring its stability.

[0053] In addition, locking pins 9 are provided at both ends of the cover plate 6. A locking hole 212 is provided on the top of the rib plate 21 near the fixed plate 22. The locking pin 9 passes through the locking hole 212 and is detachably connected to the cover plate 6. When the cover plate 6 blocks the slide groove 211, the position of the cover plate 6 is locked by the locking pin 9.

[0054] The implementation principle of Embodiment 1 of this application is as follows: the movable plate 31 can extend into the slide groove 211. By adjusting the number of movable plates 31 extending into the slide groove 211, the height of the steel mold is adjusted. After the adjustment is completed, the fixed rod 4 is slid so that the fixed rod 4 abuts against the back of the movable plate 31 to maintain the height state of the steel mold at this time.

[0055] Example 2:

[0056] Reference Figure 5 The difference between this embodiment and embodiment 1 is that limit holes 61 are provided on both sides of the cover plate 6 (the two sets of limit holes 61 are staggered in the lateral direction according to the difference in the lateral position when the cover plate 6 is opened or blocked from the slide groove 211). The end of the fixing rod 4 near the cover plate 6 extends into the limit block 7. When the cover plate 6 blocks the slide groove 211, the fixing rod 4 can abut against the cover plate 6, and the limit block 7 extends into the limit block 7 to fix the fixing rod 4 better, thereby preventing the end of the fixing rod 4 near the cover plate 6 from bending, and ensuring that the fixing rod 4 can also fix the movable plate 31 located at the lower position better.

[0057] In addition, a plug-in rod 8 is detachably connected to the fixed rod 4. In this embodiment, the plug-in rod 8 is the same length as the fixed rod 4, and the plug-in rod 8 and the fixed rod 4 are spaced apart in the lateral direction. Correspondingly, a plug-in hole 311 is provided on the movable plate 31. When the fixed rod 4 abuts against the cover plate 6, the plug-in rod 8 is inserted into the plug-in hole 311 to further fix the movable plate 31, preventing the telescopic component 3 from disengaging from the first frame 1 and the second frame 2 respectively, and ensuring that the movable plates 31 that have not been inserted into the slide groove 211 can stably maintain the situation of abutting each other end to end.

[0058] The implementation principle of Embodiment 2 of this application is as follows: by inserting the fixing rod 4 into the cover plate 6, and by inserting the connecting rod 8 into the movable plate 31, the movable plate 31 can be fixed well, so as to maintain the stability of the steel mold after the height is adjusted.

[0059] The embodiments described in this specific implementation are preferred embodiments of this application and are not intended to limit the scope of protection of this application. Identical components are represented by the same reference numerals. Therefore, all equivalent changes made to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
