Description

Technical Field

[0001] The utility model relates to the technical field of construction equipment, in particular to a contactless anti-slip step-by-step tightening device. Background Art

[0002] In construction, formwork support systems are crucial for ensuring structural safety and construction quality. In traditional construction, steel pipes are often used as support materials due to their high strength and plasticity. To improve construction efficiency and safety, a fastener that can effectively secure steel pipes and prevent their displacement is required. Bubujin, as such a fastener, is widely used in formwork support and scaffolding systems to quickly secure and reinforce steel pipes.

[0003] Existing step-by-step tightening technologies primarily include several types, including step-by-step tightening systems used in traditional timber formwork reinforcement systems, wear-resistant step-by-step tightening systems, and step-by-step tightening hardware used in construction. These step-by-step tightening systems utilize various designs to secure steel pipes. For example, they incorporate disassembly mechanisms to replace damaged stoppers, or utilize automated positioning components to reduce wear between the clamping rod and the fastening hole, thereby extending service life. However, these designs are primarily targeted at specific application scenarios and lack versatility and adaptability.

[0004] The deficiencies of the existing technology are mainly reflected in the following aspects: 1) Some step-by-step tighteners are complex in design and are not easy to install and disassemble quickly on site, which affects construction efficiency. 2) The anti-slip effect of some step-by-step tighteners is not ideal, and the stability of the steel pipe during construction cannot be guaranteed. 3) The tightening effect of existing step-by-step tighteners when in contact with concrete and steel pipes is not always satisfactory, and sometimes additional fixing measures such as expansion wires are required, which not only increases construction costs, but may also cause damage to the concrete structure. 4) The versatility and adaptability of existing step-by-step tighteners are limited, making it difficult to meet diverse construction needs. Utility Model Content

[0005] In response to the above defects or improvement needs of the prior art, the purpose of the present invention is to provide a contactless anti-slip step-by-step tightening device, which effectively increases the contact surface area and bite force by lengthening the length and width of the upper end of the movable clamp and the embedded separate rubber pad; and the use of rubber pads can prevent the step-by-step tightener from direct contact with concrete structures and metal structures, thereby increasing its service life; and the anti-slip effect can be improved by adding tightening screws and wedge-shaped plugs.

[0006] The utility model provides a contactless anti-slip step-by-step tightening device, comprising: a clamping rod, which is an L-shaped structure; a movable clamping head sleeved on the clamping rod, which is an arc-shaped structure; a tightening screw provided at the upper end of the movable clamping head; and a separate rubber pad provided at the lower end of the clamping rod and the arc-shaped inner side surface of the movable clamping head; by lengthening the length and width of the movable clamping head and arranging an embedded rubber pad, the contact surface area and the bite force are effectively increased.

[0007] Furthermore, the separate rubber pad can be replaced by a continuous rubber ring. The continuous rubber ring is a 3 / 4 circle and can wrap the steel pipe in a larger range, thereby enhancing the operability of the edge protection and the friction between the steel pipe and the rubber ring.

[0008] Furthermore, it also includes a wedge-shaped anti-slip device, which can be directly inserted into the gap between the active clamp and the clamp after the clamp rod and the active clamp are clamped, thereby improving the anti-slip performance of the device.

[0009] Furthermore, the wedge-shaped anti-slip device can be provided at the end of the clamping rod to prevent the movable clamping head from being lost, and can also be configured separately.

[0010] Furthermore, it also includes a fixed clamp head, and the fixed clamp head and the movable clamp head are arranged to cross each other at a 90-degree angle on the same plane.

[0011] Furthermore, the fixing clamp is connected to the metal template or the supporting system.

[0012] Furthermore, the movable clamp is connected to the support system.

[0013] Beneficial effects of the utility model:

[0014] 1. The utility model can effectively increase the contact surface area and bite force by lengthening the length and width of the upper end of the movable clamp and providing an embedded rubber pad. The use of the rubber pad can prevent the step-by-step clamp from directly contacting the concrete structure and metal structure, thereby increasing the service life. The anti-slip effect can be improved by adding a tightening screw and a wedge-shaped plug.

[0015] 2. For edge protection construction types, the utility model can replace the separate rubber pad with a continuous rubber pad, wrapping the steel pipe over a larger area, thereby enhancing the operability of the edge protection and the friction between the steel pipe and the edge protection.

[0016] 3. The utility model eliminates the method of fixing with expansion wire, and the construction is convenient and quick, and will not damage the structure, and no further processing is required after removal.

[0017] 4. The structural accessories of the utility model are simple, easy to operate and maintain, have a high degree of standardization, and a wide range of uses, which is conducive to promotion and use.

[0029] Example 1

[0030] like Figure 1 As shown, an embodiment of the utility model provides a basic solution for a contactless anti-slip step-by-step tightening device, including: a clamping rod 1, which is an L-shaped structure; a movable clamping head 2 sleeved on the clamping rod 1, which is an arc-shaped structure; a tightening screw 3 for fixing the clamping rod 1 and the movable clamping head 2; and a separate rubber pad 4 provided at the lower end of the clamping rod 1 and the arc-shaped inner side surface of the movable clamping head 2; by lengthening the length and width of the movable clamping head 2 and the embedded separate rubber pad 4, the contact surface area and the bite force of each contact surface are effectively increased.

[0031] Among them, a fixed clamp is provided under the clamping rod 1 and the movable clamp 2 is arranged at a 90-degree angle, so that the clamp can clamp the steel pipe at the same time as the shear wall on the other side. The intermittent rubber pad avoids direct contact between the clamp and the shear wall and steel pipe, and increases the contact area between each other. At the same time, it also generates a part of the bite force, ensuring the interaction between the clamp and the material.

[0032] Furthermore, when the steel support and the aluminum mold are reinforced, the fixed clamp and the movable clamp 2 can be arranged to cross each other at a 90-degree angle on the same plane.

[0033] Furthermore, the fixed clamp can be connected to the metal formwork or the support system, and the movable clamp is connected to the support system, which can greatly increase the operability and layout flexibility of on-site construction.

[0034] Furthermore, the inner arc diameter of the separate rubber pad 4 is 48 mm.

[0035] Example 2

[0036] like Figure 1 Figure 2 As shown, based on Example 1, the present invention proposes an improved solution for a contactless anti-slip step-by-step tightening device. This embodiment has advantages in terms of edge protection, including:

[0037] A clamping rod 1, wherein the clamping rod 1 is an L-shaped structure;

[0038] A movable clamping head 2 sleeved on the clamping rod 1, wherein the movable clamping head 2 is an arc-shaped structure;

[0039] A tightening screw 3 for fixing the clamping rod 1 and the movable clamping head 2; and

[0040] A continuous rubber ring 5 provided on the inner side of the arc-shaped movable clamp 2;

[0041] By replacing the continuous rubber ring 5 with a larger wrapping range, the operability of the edge protection and the friction between the edge protection and the steel pipe are effectively enhanced.

[0042] Among them, a fixed clamp is provided under the clamping rod 1 and the movable clamp 2 is arranged at a 90-degree angle, so that the clamp can clamp the steel pipe at the same time as the shear wall on the other side. The intermittent rubber pad avoids direct contact between the clamp and the shear wall and steel pipe, and increases the contact area between each other. At the same time, it also generates a part of the bite force, ensuring the interaction between the clamp and the material.

[0043] Furthermore, when the steel support and the aluminum mold are reinforced, the fixed clamp and the movable clamp 2 can be arranged to cross each other at a 90-degree angle on the same plane.

[0044] Furthermore, the fixed clamp can be connected to the metal formwork or the support system, and the movable clamp 2 is connected to the support system, which can greatly increase the operability and layout flexibility of on-site construction.

[0045] Furthermore, the rubber ring on the continuous rubber ring 5 is 3 / 4 circle, which can wrap the steel pipe in a larger range, enhance the operability of the edge protection and the friction between the steel pipe and the steel pipe, and at the same time ensure that the steel pipe and the concrete surface are separated by the rubber ring and do not directly contact, thereby protecting the concrete and enhancing its stability.

[0046] Example 3

[0047] like Figure 1 Figure 3 As shown, based on Example 1, the present invention proposes an improved solution for a contactless anti-slip step-by-step tightening device, including:

[0048] A clamping rod 1, wherein the clamping rod 1 is an L-shaped structure;

[0049] A movable clamping head 2 sleeved on the clamping rod 1, wherein the movable clamping head 2 is an arc-shaped structure;

[0050] A tightening screw 3 for fixing the clamping rod 1 and the movable clamping head 2; and

[0051] A separate rubber ring 4 provided between the lower end of the clamping rod 1 and the inner arc-shaped surface of the movable clamping head 2;

[0052] A fixed clamp is provided below the clamping rod 1 and is cross-arranged at 90 degrees with the movable clamp 2 in the same plane, so that the step-by-step clamp can clamp the steel pipe while also clamping the shear wall on the other side. The intermittent rubber pad avoids direct contact between the step-by-step clamp and the shear wall and steel pipe, and increases the contact area between each other. At the same time, it also generates a part of the bite force, ensuring the interaction between the step-by-step clamp and the material.

[0054] Furthermore, the fixed clamp can be connected to the metal formwork or the support system, and the movable clamp is connected to the support system, which can greatly increase the operability and layout flexibility of on-site construction.

[0055] Furthermore, it also includes a wedge-shaped anti-slip device 6, which can be directly inserted into the gap between the movable clamping head 2 and the clamping rod 1 after the clamping rod 1 and the movable clamping head 2 are clamped, thereby improving the anti-slip performance of the device.

[0056] Furthermore, the rubber wedge block 6 can be directly connected to the clamping rod and form a whole at the end of the clamping rod to prevent the movable clamping head from being lost, or it can be configured separately.

[0057] Furthermore, the rubber wedge block 6 inserted into the gap between the movable clamp head and the clamp rod can form an anti-falling component together with the tightening screw 3, thereby improving the anti-falling effect of the device.

[0058] Example 4

[0059] like Figure 2 Figure 3 As shown, based on Example 2, the present invention proposes an improved solution for a contactless anti-slip step-by-step tightening device, including:

[0060] A clamping rod 1, wherein the clamping rod 1 is an L-shaped structure;

[0061] A movable clamping head 2 sleeved on the clamping rod 1, wherein the movable clamping head 2 is an arc-shaped structure;

[0062] A tightening screw 3 for fixing the clamping rod 1 and the movable clamping head 2; and

[0063] A continuous rubber ring 5 provided on the inner side of the arc-shaped movable clamp 2;

[0064] A fixed clamp is provided below the clamping rod 1 and is cross-arranged at 90 degrees with the movable clamp 2 in the same plane, so that the step-by-step clamp can clamp the steel pipe while also clamping the shear wall on the other side. The intermittent rubber pad avoids direct contact between the step-by-step clamp and the shear wall and steel pipe, and increases the contact area between each other. At the same time, it also generates a part of the bite force, ensuring the interaction between the step-by-step clamp and the material.

[0065] Furthermore, when the steel support and the aluminum mold are reinforced, the fixed clamp and the movable clamp 2 can be arranged to cross each other at a 90-degree angle on the same plane.

[0066] Furthermore, the fixed clamp can be connected to the metal formwork or the support system, and the movable clamp is connected to the support system, which can greatly increase the operability and layout flexibility of on-site construction.

[0067] Furthermore, the rubber ring on the continuous rubber ring 5 is 3 / 4 circle, which can wrap the steel pipe in a larger range, enhance the operability of the edge protection and the friction between the steel pipe and the steel pipe, and at the same time ensure that the steel pipe and the concrete surface are separated by the rubber ring and do not directly contact, thereby protecting the concrete and enhancing its stability.

[0068] Furthermore, it also includes a wedge-shaped anti-slip device 6, which can be directly inserted into the gap between the movable clamping head 2 and the clamping rod 1 after the clamping rod 1 and the movable clamping head 2 are clamped, thereby improving the anti-slip performance of the device.

[0069] Furthermore, the rubber wedge block 6 can be directly connected to the clamping rod and form a whole at the end of the clamping rod to prevent the movable clamping head from being lost, or it can be configured separately.

[0070] Furthermore, the rubber wedge block 6 inserted into the gap between the movable clamp head and the clamp rod can form an anti-falling component together with the tightening screw 3, thereby improving the anti-falling effect of the device.

[0071] Example 5

[0072] The present invention provides a method for using a contactless anti-slip step-by-step tightening device, comprising:

[0073] Temporarily fix the position of the steel pipe or steel support as required, adjust the step-by-step tightening position so that the fixed end fixes the shear wall or metal formwork, and the movable clamp semicircle holds the steel pipe tightly. Knock the movable clamp, and the movable clamp will hold the steel pipe tightly. After tightening, tighten the screws and tighten the clamp rod to complete the reinforcement construction;

[0074] When dismantling, first loosen the tightening screws to allow the movable clamp to move freely, and then knock on the upper part of the movable clamp to complete the dismantling construction.

[0075] Furthermore, this solution is mainly for on-site application. Considering aspects such as on-site turnover rate, usage effect, and convenience of operation for workers, the number of accessories is reduced as much as possible to reduce the failure of the entire accessory due to the loss of some of its accessories.

[0076] Furthermore, during on-site construction, this device can basically be applied to cast-in-place structures (traditional square timber formwork, steel support formwork, steel formwork, and aluminum formwork). Especially in the latter three structural supports, the traditional step-by-step tightening cannot meet the tightening requirements. Its application in secondary structures and edge protection can greatly increase its turnover rate.

[0077] It should be understood that although the steps in the flowcharts of the accompanying drawings are shown in sequence as indicated by the arrows, these steps are not necessarily executed in the order indicated by the arrows. Unless otherwise specified herein, there is no strict order restriction on the execution of these steps, and they can be executed in other orders.

[0078] The above description is only part of the implementation methods of the present application. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present application. These improvements and modifications should also be regarded as the scope of protection of the present application.
