Description

Technical Field

[0001] This utility model relates to the field of building construction technology, and more specifically, to a device for preventing overturning of a building formwork support system. Background Technology

[0002] In the construction of cast-in-place concrete structures, the formwork support system is a temporary load-bearing structure used to support the self-weight of the formwork, reinforcing steel, freshly poured concrete, and construction loads. Common forms include coupler-type steel pipe scaffolding, cup-lock scaffolding, and disc-lock scaffolding. With the widespread application of high-rise buildings, large-span structures, and high-clearance floor slabs (commonly known as "high formwork"), the height and span of the formwork support system are constantly increasing. Its overall stability, especially its resistance to overturning, has become a core issue in construction safety control.

[0003] In existing formwork support devices, most only provide fixed support in the middle of the formwork, without supporting devices on the sides. This makes it easy for the sides of the formwork to shift or tilt. The problem becomes more serious when the formwork size is large. Therefore, sometimes additional support devices are added to the sides when the formwork size is large. Since each formwork requires two additional support devices, efficiency is reduced. Moreover, a large number of support devices can also affect the normal walking of workers or the efficiency of handling goods.

[0004] A search revealed a Chinese patent with publication number CN219365540U that discloses a building formwork support device for residential construction. After completing the middle support work of the formwork body, it can also provide fixed support for both sides of the formwork body. This avoids the situation where the sides shift or tilt due to the large size of the formwork and the fact that only the middle is fixedly supported. This improves the overall support strength of the formwork. Moreover, using this support device not only saves installation time but also reduces the number of support devices required.

[0005] However, in actual use, to prevent the formwork from overturning during concrete pouring, the common practice for the above-mentioned building formwork support devices is to install diagonal braces independently on the left and right sides of the formwork. However, the diagonal braces may change their support angle due to elastic deformation or connection gaps, leading to geometric instability of the support system and thus a sudden risk of overturning. Utility Model Content

[0006] In order to overcome the above-mentioned defects of the prior art, this utility model provides a building formwork support system anti-overturning reinforcement device to solve the problems mentioned in the background art.

[0007] To achieve the above objectives, this utility model provides the following technical solution:

[0008] A building formwork support system anti-overturning reinforcement device includes a support frame, on which two reinforcement components are provided;

[0009] Both of the aforementioned reinforcement components include a slide groove formed on the support frame, a threaded rod is rotatably installed in the slide groove, a movable plate is threadedly connected to the threaded rod, and the movable plate is slidably engaged with the slide groove;

[0010] Each of the two reinforcing components is provided with two support mechanisms. The support mechanisms are used to provide auxiliary support for the support frame after the reinforcing components are locked. The slide is a continuous guide groove, and its inner wall is fitted with the side wall of the movable plate to restrict circumferential rotation.

[0011] As a further description of the above technical solution:

[0012] The reinforcement component also includes two wedge-shaped blocks fixedly connected to the bottom of the movable plate. The wedge-shaped blocks have a trapezoidal cross-section and multiple limiting teeth are fixedly provided on their lower pressing surface. The limiting teeth have a conical cross-section and are arranged linearly at equal intervals.

[0013] As a further description of the above technical solution:

[0014] Multiple hinged supports are fixedly connected to the outside of the support frame, and each hinged support is hinged with a diagonal brace. The diagonal brace is used to support the ground to reinforce the support frame.

[0015] As a further description of the above technical solution:

[0016] The diagonal brace has multiple limiting grooves that correspond one-to-one with the limiting teeth. The limiting grooves are adapted to the shape of the limiting teeth to increase the contact between the wedge block's pressing surface and the diagonal brace. Furthermore, the inclined surface of the diagonal brace matches the pressing surface of the wedge block.

[0017] As a further description of the above technical solution:

[0018] The slide groove is internally threaded with a fixing bolt. The fixing bolt passes through the slide groove and extends into the threaded rod to lock the adjusted threaded rod. The thread direction of the fixing bolt is opposite to that of the thread direction of the threaded rod. The reverse thread design can prevent vibration from causing the fixing bolt to loosen and improve the locking reliability.

[0019] As a further description of the above technical solution:

[0020] The support mechanism includes a fixed plate fixedly connected to one side of the diagonal brace, and the upper surface of the fixed plate has a plurality of limit holes arranged in a ring.

[0021] As a further description of the above technical solution:

[0022] The fixed plate is internally threaded with a threaded rod II. A turntable is fixedly connected to the top of the threaded rod II. A plug rod is inserted into the turntable. The plug rod is adapted to the limiting hole and is used to limit the rotation of the turntable when inserted into the limiting hole.

[0023] As a further description of the above technical solution:

[0024] The bottom end of the threaded rod is rotatably connected to a chassis. The bottom end of the chassis is fixedly connected to multiple concentrically distributed rubber rings, each of which has a deformation opening. A rubber seat is also fixedly connected to the center of the bottom end of the chassis. Both the rubber rings and the rubber seat are made of wear-resistant and non-slip rubber, and the deformation openings are evenly distributed along the radial direction of the rubber rings. When the chassis contacts the ground, the rubber rings and the rubber seat deform together to increase friction and buffer vibration.

[0025] The technical effects and advantages of this utility model are as follows:

[0026] 1. By setting up reinforcement components, compared with existing technologies, the trapezoidal inclined surface of the wedge block cooperates with the inclined surface of the diagonal brace to automatically generate a self-locking effect when the downward pressure increases, so that the diagonal brace unfolds outward and is close to the ground. There is no need to add multiple support devices on both sides of the template. The anti-overturning reinforcement on both sides can be completed simultaneously in one operation, which greatly improves the construction efficiency. In addition, the tapered limiting teeth and the limiting groove on the diagonal brace form a multi-point mechanical engagement, which increases the contact area and frictional resistance, and significantly enhances the anti-lateral displacement ability of the diagonal brace.

[0027] 2. By setting up a support mechanism, compared with the existing technology, the bottom of the chassis is equipped with multiple rubber rings distributed in concentric circles, which can compress step by step and adaptively absorb minor unevenness of the ground. At the same time, the multi-ring structure provides redundant support. In addition to the main anti-overturning force provided by the reinforcement components, it provides additional vertical stability support, effectively suppressing the tilting of the support frame caused by lateral forces or foundation settlement, and improving anti-overturning safety.

Detailed Implementation

[0037] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0038] Example 1:

[0039] The embodiments disclosed in this application are as follows: Figure 1-8 The above-displayed anti-overturning reinforcement device for a building formwork support system includes a support frame 1, on which two reinforcement components are installed;

[0040] Both reinforcing components include a groove 2 opened on the support frame 1, a threaded rod 3 is rotatably installed in the groove 2, and a movable plate 4 is threadedly connected to the threaded rod 3, with the movable plate 4 slidingly engaging with the groove 2;

[0041] Each of the two reinforcing components is equipped with two support mechanisms. These support mechanisms provide auxiliary support for the support frame 1 after the reinforcing components are locked. The slide 2 is a continuous guide groove, and its inner wall is fitted with the side wall of the movable plate 4 to restrict circumferential rotation. The reinforcing components also include two wedge-shaped blocks 5 fixedly connected to the bottom of the movable plate 4. The cross-section of the wedge-shaped blocks 5 is trapezoidal, and multiple limiting teeth 6 are fixedly provided on their lower pressing surfaces. The cross-section of the limiting teeth 6 is conical, and the multiple limiting teeth 6 are arranged linearly at equal intervals. Multiple hinge supports 7 are fixedly connected to the outside of the support frame 1. Each hinge support 7 is hinged with a diagonal brace 8. The diagonal brace 8 is used for... The support frame 1 is reinforced by supporting the ground. The diagonal brace 8 is provided with multiple limiting grooves 9 that correspond one-to-one with the limiting teeth 6. The limiting grooves 9 and the limiting teeth 6 are adapted to each other to increase the contact between the pressing surface of the wedge block 5 and the diagonal brace 8. The inclined surface of the diagonal brace 8 matches the pressing surface of the wedge block 5. The sliding groove 2 is threaded with a fixing bolt 18. The fixing bolt 18 passes through the sliding groove 2 and extends into the threaded rod 3 to lock the adjusted threaded rod 3. The thread direction of the fixing bolt 18 is opposite to the thread direction of the threaded rod 3. The reverse thread design can prevent the fixing bolt 18 from loosening due to vibration and improve the locking reliability.

[0042] The implementation principle of this embodiment is as follows: When it is necessary to reinforce the support frame 1, firstly, the multiple diagonal braces 8 on the support frame 1 are unfolded through the hinge support 7. The threaded rod 3 is rotated using an external tool. Due to the circumferential limitation between the movable plate 4 and the slide groove 2, the movable plate 4 moves downwards along the slide groove 2. Simultaneously, the two wedge-shaped blocks 5 at its bottom move downwards. The trapezoidal cross-section of the wedge-shaped blocks 5 causes their downward pressing surface to gradually contact the inclined surface of the diagonal brace 8 and apply downward pressure, making the bottom end of the diagonal brace 8 press firmly against the ground. At the same time, the wedge-shaped blocks... Multiple tapered limiting teeth 6, fixedly installed on the lower pressure surface of block 5, are inserted into the corresponding limiting grooves 9 on the diagonal brace 8, forming a mechanical fit. The downward pressure is transmitted to the diagonal brace 8 through the cooperation of the limiting teeth 6 and the limiting grooves 9. As the wedge block 5 continues to move downward, the diagonal brace 8 is subjected to an outward horizontal component force, forming a mechanical fit, which increases the anti-slip ability between the contact surfaces. On the other hand, it prevents relative sliding between the wedge block 5 and the diagonal brace 8, thus stably transmitting the downward pressure as the supporting force of the diagonal brace 8. After adjustment, the fixing bolt 18 connected to the internal thread of the slide groove 2 is tightened so that it passes through the slide groove 2 and extends into the threaded rod 3. Since the thread direction of the fixing bolt 18 is opposite to the thread direction of the threaded rod 3, the two form a two-way locking, which can effectively prevent the threaded rod 3 from loosening due to construction vibration or load changes, ensuring that the reinforcement component remains stable and reliable during long-term use, thereby enhancing the anti-lateral displacement ability of the two diagonal braces 8 on the support frame 1.

[0043] Example 2:

[0044] Based on Example 1, this example discloses an anti-overturning reinforcement device for a building formwork support system, referring to... Figure 3 , 7 As shown in Figure 8, the support mechanism includes a fixed plate 10 fixedly connected to one side of the diagonal brace 8. The upper surface of the fixed plate 10 has multiple annularly distributed limiting holes 11. A threaded rod 12 is threaded into the fixed plate 10. A turntable 13 is fixedly connected to the top of the threaded rod 12. A rod 14 is inserted into the turntable 13, and the rod 14 is adapted to the limiting holes 11 to restrict the rotation of the turntable 13 when inserted into the limiting holes 11. A base 15 is rotatably connected to the bottom end of the threaded rod 12. Multiple concentrically distributed rubber rings 16 are fixedly connected to the bottom end of the base 15, and each rubber ring 16 has a deformation opening. A rubber seat 17 is also fixedly connected to the center of the bottom end of the base 15. Both the rubber rings 16 and the rubber seat 17 are made of wear-resistant and non-slip rubber, and the deformation openings are evenly distributed radially along the rubber rings 16. When the base 15 contacts the ground, the rubber rings 16 and the rubber seat 17 deform together, increasing friction and buffering vibration.

[0045] The implementation principle of this embodiment is as follows: After the diagonal brace 8 forms a stable support with the ground, the turntable 13 is rotated by an external tool. The turntable 13 drives the threaded rod 12 to rotate within the fixed plate 10. Due to the threaded engagement, the threaded rod 12 moves up and down relative to the fixed plate 10, so that the base plate 15 at the bottom of the threaded rod 12 is in close contact with the ground. When there are slight unevennesses on the ground, as the base plate 15 continues to press down, the outer rubber ring 16 first contacts the ground and undergoes elastic compression. Its open structure allows the ring to contract radially to adapt to local protrusions. If the unevenness of the ground is large, the inner rubber ring 16 and the central rubber seat 17 participate in the compression in sequence, forming a multi-level adaptive fit, so that the base plate 15 always maintains a large area of ​​stable contact with the ground.

[0046] After the chassis 15 makes stable contact with the ground, the insert rod 14 is inserted into the turntable 13 and locked into the corresponding limit hole 11. At this time, the turntable 13 is completely locked, and the threaded rod 12 can no longer rotate, thereby preventing the threaded rod 12 from loosening due to external force or vibration. In addition to the anti-overturning force provided by the reinforcement component, it provides additional vertical stability support, effectively suppressing the tilt of the support frame 1 caused by lateral force or foundation settlement.
