Description

Technical Field

[0001] This utility model relates to the field of concrete formwork production technology, and in particular to an adjustable fair-faced concrete formwork steel frame structure. Background Technology

[0002] Fair-faced concrete formwork is a special formwork system used for pouring fair-faced concrete, which is concrete whose surface is directly used as a decorative surface and does not require secondary finishing such as plastering or painting. During the pouring process of fair-faced concrete formwork, steel frames are used to support the formwork in order to provide the concrete with a precise geometric contour.

[0003] Currently, the existing steel frame structure for fair-faced concrete formwork is relatively simple. After the concrete has solidified, it will stick to the inner wall of the steel frame due to the influence of temperature and humidity. Therefore, when removing it, workers need to knock on the formwork to separate the steel frame from the fair-faced concrete. This not only makes the removal process difficult, but also easily damages the steel frame during the knocking process. To address these issues, we propose an adjustable steel frame structure for fair-faced concrete formwork. Utility Model Content

[0004] The purpose of this utility model is to address the shortcomings of existing technologies by proposing an adjustable fair-faced concrete formwork steel frame structure.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: An adjustable fair-faced concrete formwork steel frame structure includes a steel frame body. The interior of the steel frame body has a rectangular groove, and a movable plate is inserted inside the rectangular groove. A first cover frame is distributed on the left side of the steel frame body, and a threaded rod is inserted inside the first cover frame. The movable plate has a threaded groove inside that matches the threaded rod. A connecting rod abuts against the top of the movable plate, and the connecting rod passes through the inner wall of the steel frame body and connects to a push plate. The push plate is inserted inside the steel frame body.

[0006] Preferably, a second covering frame is distributed on the right side of the steel frame body, and the cross-sectional area of ​​the second covering frame is larger than that of the rectangular groove.

[0007] Preferably, positioning posts are fixedly connected to the top of the first cover frame and the second cover frame respectively, and positioning grooves adapted to the positioning posts are opened on the bottom walls of the first cover frame and the second cover frame.

[0008] Preferably, the first and second cover frames are symmetrically provided with reserved slots inside, and the interior of the reserved slots is connected to the outer wall of the steel frame body by bolts. The outer wall of the steel frame body is provided with screw holes that are compatible with the bolts.

[0009] Preferably, a rotating bar is fixedly connected above the threaded rod, and the rotating bar is configured as a long strip structure.

[0010] Preferably, the bottom of each connecting rod is fixedly connected to a connecting block, and the bottom of each connecting block is in contact with the top of the moving plate. A connecting spring is fixedly connected to the top of each connecting block, and slots that match the connecting springs are evenly opened inside the steel frame body.

[0011] Compared with the prior art, the beneficial effects of this utility model are as follows: 1. This device, equipped with a movable plate and a threaded rod, allows workers to quickly demold the molded template after the fair-faced concrete formwork is formed inside the steel frame body. Workers only need to rotate the threaded rod to drive the movable plate and the push plate to lift, thus achieving rapid demolding without workers needing to knock on the outer wall of the steel frame body. This effectively improves the convenience of the demolding process.

[0012] 2. The device is equipped with positioning columns and positioning slots. During use, the positioning columns and positioning slots work together to limit the position of the stacked steel frame bodies, thereby ensuring the stability and reliability of the steel frame bodies when stacked.

[0015] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0016] Reference Figure 1-5 An adjustable fair-faced concrete formwork steel frame structure includes a steel frame body 1. The interior of the steel frame body 1 has a rectangular groove 5, and a movable plate 4 is inserted inside the rectangular groove 5. A first covering frame 2 is distributed on the left side of the steel frame body 1, and a threaded rod 3 is inserted inside the first covering frame 2. The interior of the movable plate 4 has a threaded groove that matches the threaded rod 3. A connecting rod 7 abuts against the top of the movable plate 4, and the connecting rod 7 passes through the inner wall of the steel frame body 1 and is connected to a push plate 6. The push plate 6 is inserted inside the steel frame body 1.

[0017] Furthermore, refer to Figure 2 It can be seen that a second covering frame 8 is distributed on the right side of the steel frame body 1, and the cross-sectional area of ​​the second covering frame 8 is larger than that of the rectangular groove 5. Through the second covering frame 8 distributed on the right side of the steel frame body 1, and because the cross-sectional area of ​​the second covering frame 8 is larger, the opening on the right side of the rectangular groove 5 can be covered, thereby effectively preventing debris from entering the interior of the rectangular groove 5.

[0018] Furthermore, refer to Figure 2 and Figure 4 It can be seen that positioning posts 12 are fixedly connected to the top of the first cover frame 2 and the second cover frame 8 respectively. Positioning grooves 13 adapted to the positioning posts 12 are opened on the bottom walls of the first cover frame 2 and the second cover frame 8. During the stacking of multiple sets of steel frame bodies 1, the positioning grooves 13 opened on the bottom walls of the upper first cover frame 2 and the second cover frame 8 can be inserted into the positioning posts 12 opened on the top of the lower first cover frame 2 and the second cover frame 8, thereby effectively ensuring the stability of the steel frame bodies 1 during the stacking process.

[0019] Furthermore, refer to Figure 2 and Figure 4 It can be seen that the first cover frame 2 and the second cover frame 8 have symmetrically provided reserved slots inside, and the interior of the reserved slots is connected to the outer wall of the steel frame body 1 by bolts. The outer wall of the steel frame body 1 has screw holes that are compatible with the bolts. During use, the first cover frame 2 and the second cover frame 8 can be easily removed from the side of the steel frame body 1 by means of the reserved slots on the side of the first cover frame 2, the bolts and the screw holes on the side of the steel frame body 1, so that the workers can replace the damaged threaded rod 3 inside the first cover frame 2.

[0020] Furthermore, refer to Figure 3 It can be seen that a rotating bar 9 is fixedly connected to the top of the threaded rod 3, and the rotating bar 9 is set as a long strip structure. Through the rotating bar 9 set as a long strip structure, the operator can quickly rotate the threaded rod 3, thereby effectively improving the convenience of using this device.

[0021] Furthermore, refer to Figure 3 It can be seen that connecting blocks 10 are fixedly connected to the bottom of connecting rod 7, and the bottom of each connecting block 10 is in contact with the top of the moving plate 4. A connecting spring 11 is fixedly connected to the top of the connecting block 10. The interior of the steel frame body 1 is evenly provided with slots that are compatible with the connecting spring 11. When the operator rotates the rotating bar 9 in the opposite direction to drive the threaded rod 3 and the moving plate 4 to engage with the threaded connection, and causes the moving plate 4 to move downward under force, the connecting blocks 10 connected to the bottom wall of connecting rod 7 and the connecting spring 11 connected to the top of the connecting blocks 10 can easily cause the pushing plate 6 and the moving plate 4 to automatically reset due to the elastic force of the connecting spring 11, without the need for manual operation by the operator. Working principle: When using this utility model, the operator can first place the device in a suitable position, and then pour the fair-faced concrete template into the interior of the steel frame body 1, and let it stand for a period of time to wait for the template to form. After the template is formed, the operator can first rotate the rotating bar 9, which can drive the threaded rod 3 to rotate at the same time. At this time, the moving plate 4 sleeved on the outside of the threaded rod 3 can be threadedly engaged with the threaded rod 3. Since the top of the moving plate 4 abuts against each group of connecting blocks 10 and connecting rod 7, and since the top of the connecting rod 7 is fixedly connected to the push plate 6, when the moving plate 4 is lifted, it can drive the push plate 6 to be lifted, thereby pushing out the template inside the steel frame body 1 to help the template to be demolded quickly. When the threaded rod 3 becomes stripped after prolonged use, the operator can use an auxiliary tool to remove the bolts inside the first cover frame 2. Then, the first cover frame 2 can be separated from the side of the steel frame body 1. The operator can then push the first cover frame 2 laterally to move the moving plate 4 at the same time, thereby pulling the moving plate 4 out from the inside of the rectangular groove 5 to replace the threaded rod 3 and the first cover frame 2. The above is the complete working principle of this utility model.
