Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of building construction. More specifically, the utility model is a rust-proof protection device for steel reinforcement cages. Background Art
[0002] In construction projects, steel bars play an indispensable role. Especially in large-scale projects, the consumption often exceeds tens of thousands of tons. Steel bars have the following properties: toughness, hardness, plasticity, strength, brittleness, fatigue strength, yield point or yield stress, ductility, rigidity, and elasticity. However, steel bars also have significant defects, one of which is easy to rust. Rust, this seemingly minor natural phenomenon, poses a serious threat to the performance of steel bars. At the construction site, especially during the processing and installation of steel reinforcement cages, a large number of steel reinforcement cages are inevitably exposed to the air. At this time, if they encounter a humid, rainy, or high-salt environment, the surface of the steel bars is extremely likely to undergo an oxidation reaction, forming a rust layer. This rust not only weakens the cross-sectional area of the steel bars, reducing their load-bearing capacity, but also may cause stress concentration, accelerating the process of fatigue failure. More seriously, during the long winter shutdown period in the northern region, when the steel reinforcement cages are covered by thick snow, due to the sudden drop in temperature and the increase in humidity, the rusting speed doubles, posing a potential risk to the quality and safety of construction projects.
[0003] To address this challenge, the traditional approach is to cover the steel reinforcement cages with plastic films. However, although this method is simple and easy to implement, it has many limitations. On the one hand, the durability of plastic films is poor and they are extremely easy to break under harsh weather conditions such as strong winds and heavy rains. On the other hand, affected by natural factors such as monsoons, the covering effect of the films is often difficult to guarantee. Especially in the windy season, the films may even be blown off, completely losing their protective effect. Therefore, this traditional rust-proof measure often fails to achieve the desired effect in practical applications.
[0004] Another more common rust-proof method is to apply rust-proof coatings. This method forms a dense protective film on the surface of the steel bars to isolate the direct contact between air and moisture and the steel bars, thereby achieving the purpose of rust prevention. However, this method also has problems that cannot be ignored. First, the application of rust-proof coatings requires the entire exposed steel reinforcement cage to be coated, consuming a large amount of manpower and material resources. Second, when construction resumes and concrete is poured, these steel bars coated with rust-proof coatings will be permanently wrapped inside the concrete, which is actually a great waste of rust-proof coatings. Finally, the price of rust-proof coatings is not low, increasing the construction cost accordingly. Summary of the Utility Model
[0005] To solve the technical problem of high anti-rust expenditure of the existing steel reinforcement cage, the utility model innovatively provides a steel reinforcement cage anti-rust protection device, which can effectively prevent the steel reinforcement cage from rusting, and also has the advantages of simple structure, reusable, convenient for storage and easy to use.
[0006] To achieve the above technical purpose, the utility model discloses a steel reinforcement cage anti-rust protection device, which includes a columnar flexible protection sleeve. The flexible protection sleeve can be compressed and deformed along its own axis direction. An upper end of the flexible protection sleeve is provided with a strengthening layer. The lower end of the flexible protection sleeve is open, and a hook is provided at an opening of the lower end of the flexible protection sleeve. A plurality of circumferential constraint kits are sleeved on an outer peripheral wall of the flexible protection sleeve at intervals.
[0007] Further, in the steel reinforcement cage anti-rust protection device of the utility model, the strengthening layer includes an outer strengthening plate, and the outer strengthening plate is vulcanized and bonded to a top end of the outside of the flexible protection sleeve.
[0008] Further, in the steel reinforcement cage anti-rust protection device of the utility model, the strengthening layer further includes an inner strengthening plate. The inner strengthening plate is vulcanized and bonded to a top end of the inside of the flexible protection sleeve. The inner strengthening plate and the outer strengthening plate overlap each other in the vertical direction to clamp the flexible protection sleeve between the outer strengthening plate and the inner strengthening plate.
[0009] Further, in the steel reinforcement cage anti-rust protection device of the utility model, the hook at the opening of the flexible protection sleeve includes a first hook and a second hook which are symmetrically arranged. Fixed ends of the first hook and the second hook are both connected to the flexible protection sleeve, and free ends of the first hook and the second hook are both bent towards the inside of the flexible protection sleeve.
[0010] Further, in the steel reinforcement cage anti-rust protection device of the utility model, a connecting ring is wound at the opening of the lower end of the flexible protection sleeve, and the fixed ends of the first hook and the second hook both pass through the flexible protection sleeve and are welded and fixed to the connecting ring.
[0011] Further, in the steel reinforcement cage anti-rust protection device of the utility model, both the first hook and the second hook include two symmetrically arranged hook bodies.
[0012] Further, in the steel reinforcement cage anti-rust protection device of the utility model, the constraint kit includes an elastic ring and a pressing ring. The elastic ring is sleeved on the outer peripheral wall of the flexible protection sleeve, and the pressing ring is sleeved on the outer peripheral wall of the elastic ring.
[0013] Further, in the steel reinforcement cage anti-rust protection device of the utility model, cross-sectional shapes of both the elastic ring and the pressing ring are flat, and a width of the elastic ring is greater than a width of the pressing ring.

[0015] Further, in a rust-proof protection device for a steel reinforcement cage of the present utility model, the pressing ring is welded by stainless steel pressing strips.
[0016] The difference between the present utility model and the prior art lies in that: by providing a columnar flexible protective sleeve, the flexible protective sleeve can be compressed and deformed along its own axial direction, a strengthening layer is provided at the upper end of the flexible protective sleeve, the lower end of the flexible protective sleeve is open, a hook is provided at the opening of the lower end of the flexible protective sleeve, and a plurality of circumferential restraint kits are arranged at intervals on the outer peripheral wall of the flexible protective sleeve, thereby constituting a rust-proof protection device for a steel reinforcement cage with a simple structure, reusable, easy to store and convenient to use.

[0022] The following will explain and illustrate in detail a rust-proof protection device for a steel reinforcement cage of the present utility model with reference to the accompanying drawings of the specification.
[0023] As Figure 1 shown, the utility model discloses a rust-proof protection device for steel reinforcement cages, which is provided with a columnar flexible protective sleeve 1. The flexible protective sleeve 1 can be made of a composite material plastic nylon 46. The flexible protective sleeve 1 can be compressed and deformed along its own axial direction. An enhanced layer 2 is provided at the upper end of the flexible protective sleeve 1, and the lower end of the flexible protective sleeve 1 is open. A hook 3 is provided at the opening of the lower end of the flexible protective sleeve 1, and a plurality of circumferentially distributed circumferential restraint kits 4 are sleeved on the outer peripheral wall of the flexible protective sleeve 1, thus constituting a rust-proof protection device for steel reinforcement cages with a simple structure, reusable, convenient for storage and easy to use. In the actual application process, in the storage state, the flexible protective sleeve 1 is in a compressed state, so it can be stored in large quantities; when in use, only need to place the flexible protective sleeve 1 at the upper end of the steel reinforcement cage (as Figure 4 shown), make the upper end of the steel bar abut against the enhanced layer 2, and then drag it from top to bottom until it reaches the root of the steel reinforcement cage, then hang the hook 3 on the root of the steel reinforcement cage, and finally adjust the position of the circumferential restraint kit 4 on the flexible protective sleeve 1 (as Figure 5 shown), cover the steel reinforcement cage with the flexible protective sleeve 1, and apply rust-proof paint at the root of the steel reinforcement cage, which can effectively protect the surface of the steel bar from rust. The construction process is simple and convenient, and only one worker is needed to complete the installation, saving labor costs. And this device also has the characteristic of being reusable, thus reducing the cost of steel bar rust prevention and achieving the purpose of reducing costs and increasing efficiency in project construction.
[0024] As Figure 2 shown, in an embodiment of the utility model, the enhanced layer 2 includes an outer reinforcement plate 21 and an inner reinforcement plate. The outer reinforcement plate 21 is fixed to the outer top end of the flexible protective sleeve 1 through a vulcanization bonding process, and the inner reinforcement plate is bonded to the inner top end of the flexible protective sleeve 1 in the same way. The inner and outer reinforcement plates 21 overlap each other in the vertical direction, so as to firmly place the flexible protective sleeve 1 between the two. The reinforcement plate can be made of an elastic polymer material, such as natural rubber, synthetic rubber (including styrene-butadiene rubber, nitrile rubber, chloroprene rubber), thermoplastic elastomer (such as SBS, SEBS, TPU, TPE), silicone rubber, polyurethane, etc. Adopting the structure of the enhanced layer 2 can significantly improve the wear resistance of the top end of the flexible protective sleeve 1 and effectively prevent the steel bars of the steel reinforcement cage from piercing through the flexible protective sleeve 1 due to friction, thereby extending the service life of the flexible protective sleeve 1
[0025] As Figure 3As shown, in an embodiment of the present utility model, the hook 3 at the opening of the flexible protective sleeve 1 includes a first hook 31 and a second hook 32 which are symmetrically arranged. The fixed ends of the first hook 31 and the second hook 32 are both connected to the flexible protective sleeve 1, and the free ends of the first hook 31 and the second hook 32 are both bent towards the inner side of the flexible protective sleeve 1. This setting method not only saves space, but also greatly improves the convenience and stability of hanging objects, and can prevent the hook 3 from piercing itself or other flexible protective sleeves 1 during stacking. The specific fixing method of the first hook 31 and the second hook 32 is as follows: a connecting ring 5 is wound at the opening at the lower end of the flexible protective sleeve 1 (that is, the connecting ring 5 is wrapped inside the flexible protective sleeve 1), and the fixed ends of the first hook 31 and the second hook 32 both pass through the flexible protective sleeve 1 and are welded and fixed to the connecting ring 5. By setting the connecting ring 5, the first hook 31 and the second hook 32 can be firmly arranged on the flexible protective sleeve 1, which can not only reduce the damage to the flexible protective sleeve 1, but also improve the bearing capacity of the first hook 31 and the second hook 32, and avoid tearing the flexible protective sleeve 1 due to bad weather such as strong wind. In order to further improve the hanging effect of the hook 3, both the first hook 31 and the second hook 32 include two symmetrically arranged hook bodies, which not only increases the contact area between the hook 3 and the root of the steel reinforcement cage, improves the bearing capacity, but also makes the hook 3 more balanced and stable when stressed, effectively avoiding the damage risk caused by excessive single-point stress.
[0026] As Figure 2 shown, in an embodiment of the present utility model, the restraint kit 4 includes an elastic ring 41 and a pressing ring 42. The elastic ring 41 is sleeved on the outer peripheral wall of the flexible protective sleeve 1 to cope with external impacts and vibrations. The elastic ring 41 is mostly made of high-quality elastic webbing material. This material not only has good stretching performance, can automatically adjust the tightness under different conditions, ensure the fitting degree, but also can effectively absorb and disperse external stress. The pressing ring 42 is sleeved on the outer peripheral wall of the elastic ring 41, providing a solid support for the entire restraint kit 4. The pressing ring 42 is made of a stainless steel strip through welding, and it has excellent corrosion resistance and high strength, and can ensure long-term stable operation in a harsh environment. The cross-sectional shapes of the elastic ring 41 and the pressing ring 42 are both set to be flat, which can effectively increase the contact area with the elastic ring 41 and the flexible protective sleeve 1, and improve the overall connection strength and stability. It should be noted that the width design of the pressing ring 42 is smaller than the width of the elastic ring 41. Such a size difference not only ensures the tight fit between the two, but also avoids assembly difficulties or damage to the flexible protective sleeve 1 caused by being too tight.
