Description

Technical Field

[0001] This utility model relates to the field of building engineering technology, and in particular to a fiberglass reinforced steel cage protection device. Background Technology

[0002] Fiberglass reinforced steel cages are steel cages that use fiberglass reinforcement bars instead of ordinary steel bars in certain areas. Fiberglass reinforcement bars can significantly improve the corrosion resistance and electrical insulation of the steel cage in the corresponding areas, making them particularly suitable for projects such as ports, docks, and substations where the corrosion resistance of the steel cage is high or where the environment is sensitive to electromagnetic fields. However, compared to ordinary steel bars, fiberglass reinforcement bars have a lower modulus of elasticity, making them prone to breakage and damage during transportation or hoisting due to undesigned loads or impacts, which increases construction costs. Therefore, there is an urgent need to develop a protective device for fiberglass reinforced steel cages. Utility Model Content

Detailed Implementation

[0016] The present invention will be further described in detail below with reference to specific embodiments. However, it should not be construed as limiting the scope of the present invention to the following embodiments; all technologies implemented based on the content of the present invention fall within the scope of the present invention.

[0017] Unless otherwise specified, the use of terms such as "upper," "lower," "left," "right," "center," "inner," and "outer" to indicate orientation or positional relationships in the description of specific embodiments of this utility model is based on the orientation or positional relationships shown in the accompanying drawings, or the orientation or positional relationship in which the utility model product / equipment / device is typically placed during use. These terms are merely for the purpose of facilitating the description of the utility model solution or simplifying the description in specific embodiments, enabling those skilled in the art to quickly understand the solution, and do not indicate or imply that a specific device / component / element must have a specific orientation, or be constructed and operated in a specific positional relationship. Therefore, they should not be construed as limitations on this utility model.

[0018] Furthermore, the use of terms such as "horizontal," "vertical," "suspended," and "parallel" does not imply that the corresponding device / component / element must be absolutely horizontal, vertical, suspended, or parallel, but rather that it can be slightly tilted or have a deviation. For example, "horizontal" merely means that its direction is more horizontal relative to "vertical," not that the structure must be completely horizontal, but can be slightly tilted. Alternatively, it can be simplified to mean that the corresponding device / component / element, when set in a "horizontal," "vertical," "suspended," or "parallel" direction, can have an error / deviation of ±10% relative to the corresponding direction, more preferably within ±8%, more preferably within ±6%, more preferably within ±5%, and more preferably within ±4%. As long as the corresponding device / component / element is within the error / deviation range, it can still achieve its function in the present invention.

[0019] Furthermore, the use of terms such as "first," "second," and "third" in terminology is merely for distinguishing descriptions of identical or similar components and should not be interpreted as emphasizing or implying the relative importance of a particular component.

[0020] Furthermore, in the description of the embodiments of this utility model, "several", "multiple", and "several" represent at least two. The number can be any number, such as two, three, four, five, six, seven, eight, or nine, and can even exceed nine.

[0021] Furthermore, in the description of the technical solution of this utility model, unless otherwise explicitly specified / limited / restricted, the terms "set up," "install," "connect," "link," "equipped with," "laid out," and "arranged" should be interpreted broadly. For example, they can refer to fixed connections, detachable connections, or integral connections; they can refer to common connection methods in the art, such as welding, riveting, bolting, and threaded connections. Such connections can be mechanical, electrical, or communication connections; they can be direct connections or indirect connections through an intermediate medium; and they can refer to the internal communication between two components.

[0022] Example 1 like Figures 1 to 9As shown, a fiberglass reinforced steel cage protection device includes a hoop assembly 1 and a longitudinal connecting rod 2; at least two hoop assemblies 1 are coaxially spaced, and adjacent hoop assemblies 1 are connected to each other by the longitudinal connecting rod 2, the axis of the longitudinal connecting rod 2 being arranged along the distribution direction of the hoop assemblies 1; each hoop assembly 1 includes a first ring unit and a second ring unit coaxially arranged, the diameter of the first ring unit and the second ring unit being larger than the outer diameter of the steel cage 4, a first clamp 111 being connected to the inner side of the first ring unit, and a second clamp 121 being arranged on the inner side of the second ring unit; the relative angle between the first ring unit and the second ring unit along the circumference of the hoop assembly 1 is adjustable, so that the first clamp 111 and the second clamp 121 can be adjusted as follows. Figure 6 As shown, they move closer to each other, and then as Figure 7 The longitudinal reinforcement 41 of the steel cage 4 is clamped as shown; or the first jaw 111 and the second jaw 121 can be clamped as shown. Figure 8 As shown, they move away from each other, thereby loosening the longitudinal bars 41 of the steel cage 4.

[0023] This embodiment can form a protective cage on the outside of the reinforcing cage 4 by using the hoop assembly 1 and the longitudinal connecting rod 2. When in use, the protective cage is placed over the area where the glass fiber reinforcement is located, and the relative angle of the first ring unit and the second ring unit is adjusted so that the first and second clamps clamp the longitudinal reinforcement 41 of the reinforcing cage 4. This fixes the protective cage on the outside of the glass fiber reinforcement area of ​​the reinforcing cage 4, which can provide additional support and protection for the glass fiber reinforcement area and prevent foreign objects from directly impacting the glass fiber reinforcement. This can significantly reduce the risk of damage to the glass fiber reinforcement during transportation and hoisting, thereby helping to reduce construction costs.

[0024] In an optional embodiment, the specific size, quantity, and distribution distance of the hoop assembly 1 are determined according to the actual situation of the reinforcing cage 4. It is preferable that the inner diameter of the first ring unit and the second ring unit are both larger than the outer diameter of the reinforcing cage 4, the distance between the hoop assemblies 1 at both ends is greater than the length of the glass fiber reinforcement, and the hoop assemblies 1 at both ends extend beyond the ends of the glass fiber reinforcement. In this way, the hoop assemblies 1 at both ends can be connected to the ordinary steel longitudinal reinforcement 41 at both ends of the glass fiber reinforcement, so that the hoop assembly 1 and the longitudinal connecting rod 2 can replace the glass fiber reinforcement to transfer the load between the ordinary steel longitudinal reinforcement 41 at both ends, thereby significantly reducing the load borne by the glass fiber reinforcement (the principle is similar to the fixation splint used to treat fractures), and further reducing the risk of damage to the glass fiber reinforcement during transportation and hoisting.

[0025] In an optional embodiment, the number of longitudinal connecting rods 2 is at least two, and the longitudinal connecting rods 2 are distributed at intervals along the circumference of the ring assembly 1, so as to more stably connect each ring assembly 1.

[0026] In optional embodiments, the adjustable relative angle between the first ring unit and the second ring unit can be achieved through various structures; for example, a number of mounting points are set at intervals on the first ring unit along the circumference of the first ring unit for the second ring unit, and the relative angle between the first ring unit and the second ring unit can be changed by mounting the second ring unit at different mounting points. The specific form of the mounting points includes, but is not limited to, mounting holes, mounting slots or mounting pins; or the first ring unit and the second ring unit are connected by a rotating mechanism, so that their relative angle can be changed directly by rotating the first ring unit and the second ring unit relative to each other.

[0027] In an optional embodiment, one of the first ring unit and the second ring unit is provided with an arc-shaped groove 113. The length of the arc-shaped groove 113 is set along the circumference of the ring assembly 1. The center of the arc-shaped groove 113, the axis of the first ring unit, and the axis of the second ring unit are all collinear. The other of the first ring unit and the second ring unit is connected to a limiting pin 3. The limiting pin 3 passes through the arc-shaped groove 113, so that the limiting pin 3 can slide relative to the arc-shaped groove 113 within the length range of the arc-shaped groove 113, thereby providing the second ring unit with a rotational degree of freedom of the corresponding angle, and thus realizing the adjustment of the relative angle between the first ring unit and the second ring unit.

[0028] This embodiment provides a specific structure that enables the relative angle adjustment between the first ring unit and the second ring unit, which has the advantages of simple structure and reliable operation.

[0029] In an optional embodiment, a second ring unit is provided on both sides of the first ring unit, an arc-shaped groove 113 is provided on the first ring unit, and the two ends of the limiting pin 3 are respectively connected to the second ring units on both sides.

[0030] This embodiment sandwiches the first ring unit between two second ring units, forming a sandwich structure. On the one hand, this makes the forces on the first ring unit and the second ring units on both sides more balanced, which is beneficial to improving the connection reliability between the first ring unit and the second ring unit, as well as the certainty and smoothness of the rotational freedom between the first ring unit and the second ring unit, so that the workers can adjust the relative angle between the first ring unit and the second ring unit more smoothly. On the other hand, it can also increase the number of second claws in a single ring assembly 1, so that this embodiment can clamp the longitudinal rib 41 more stably.

[0031] In an optional embodiment, the number of arc-shaped grooves 113 is at least two, and the arc-shaped grooves 113 are distributed circumferentially along the first ring unit.

[0032] In an optional embodiment, the limiting pin 3 includes a quick-release lever; the quick-release lever can be an existing product, such as a bicycle quick-release self-locking handle disclosed in publication number CN101585392A, with its screw passing through the arc-shaped slide groove 113 and its two ends abutting against the second ring units on both sides respectively; pressing the handle can drive the first ring unit and the second ring unit to press against each other, thereby using the friction between the first ring unit and the second ring unit to lock their relative angle, so that the first gripper 111 and the second gripper 121 can stably clamp the longitudinal rib 41; releasing the handle can reduce the pressure between the first ring unit and the second ring unit, thereby unlocking the rotational freedom between the first ring unit and the second ring unit, so that the operator can more easily and efficiently separate the ring assembly 1 and the longitudinal rib 41.

[0033] In optional implementations, such as Figure 5 As shown, the limit pin 3 can also be a common screw with a nut connected to one end, so that the rotational freedom between the first ring unit and the second ring unit can be locked or unlocked by tightening or loosening the nut.

[0034] In an optional embodiment, the longitudinal connecting rod 2 includes a first connecting rod 21 and a second connecting rod 22; a first connecting member 112 is provided on the outer side of the first ring unit, and the specific form of the first connecting member 112 includes, but is not limited to, a connecting plate, a connecting seat, or a connecting hole; the first connecting rod 21 passes through at least two first connecting members 112 to connect the corresponding first ring units to each other; a second connecting member 122 is provided on the outer side of the second ring unit, and the specific form of the second connecting member 122 includes, but is not limited to, a connecting plate, a connecting seat, or a connecting hole; the second connecting rod 22 passes through at least two second connecting members 122 to connect the corresponding second ring units to each other.

[0035] Since the ring assembly 1 includes a first ring unit and a second ring unit, this embodiment correspondingly includes a first connecting rod 21 and a second connecting rod 22 to be responsible for the longitudinal connection of two adjacent first ring units and the longitudinal connection of two adjacent second ring units, respectively. This not only improves the structural strength of this embodiment by using more connecting rods, but also allows at least two first ring units to be connected to each other by the first connecting rod 21 and at least two second ring units to be connected to each other by the second connecting rod 22. This enables the linkage of at least two first ring units and at least two second ring units, thereby improving the efficiency of workers in adjusting the relative angle between the first ring units and the second ring units.

[0036] In an optional embodiment, the ring assembly 1 is divided into at least two groups along its distribution direction, and each ring assembly 1 in the same group is connected to each other by one of the first connecting rod 21 and the second connecting rod 22; two adjacent groups of ring assemblies 1 are detachably connected to each other by the other of the first connecting rod 21 and the second connecting rod 22, and the specific forms of detachable connection include but are not limited to threaded connection, flange connection, tenon connection or snap connection.

[0037] For example Figure 2 As shown, the eight ring assemblies 1 are divided into two groups. Four ring assemblies 1 in the same group are interconnected by several first connecting rods 21. The first connecting rods 21 pass directly through the first connecting pieces 112 of the four ring assemblies 1, connecting them into a cage-like unit. The two groups of ring assemblies 1 are interconnected by several second connecting rods 22. The two ends of the second connecting rods 22 extend towards the two groups of ring assemblies 1 and pass through the second connecting pieces 122 of at least two ring assemblies 1, ensuring reliable connection between adjacent groups of ring assemblies 1. Furthermore, the second connecting rods 22 and the second connecting pieces 122 are detachably connected, thus enabling... Figure 2 As shown, by removing the second connecting rod 22 between two adjacent sets of ring assemblies 1, this embodiment is divided into two shorter cage-like units, which helps to reduce the difficulty of transportation, hoisting and storage of this embodiment.

[0038] It should be noted that the above implementation method is only one example. In actual construction, the grouping of the hoop assembly 1, the setting position of the first connecting rod 21 and the second connecting rod 22, the number of first connecting parts 112 through which the first connecting rod 21 passes, and the number of second connecting parts 122 through which the second connecting rod 22 passes can all be adjusted according to the actual situation of the steel cage 4.

[0039] In optional implementations, such as Figure 5 As shown, the first connector 112 adopts a perforated ear plate, and the first connecting rod 21 passes through the perforated ear plate and is welded to the perforated ear plate, thereby realizing the permanent connection between the first connecting rod 21 and the first ring unit to ensure the structural stability of the single cage unit.

[0040] In optional implementations, such as Figure 5 As shown, the second connector 122 adopts an openable latch. Opening the latch allows the second connecting rod 22 to be inserted into the second connector 122, and closing the latch connects the second connecting rod 22 to the second connector 122, thereby achieving the mutual connection of the corresponding second ring units. Opening the latch again allows the second connecting rod 22 to be removed from the second connector 122, thereby disconnecting the mutual connection of the corresponding second ring units.

[0041] In an optional embodiment, the hoop assembly 1 is divided into at least two arc-shaped segments 10 along its circumference, and adjacent arc-shaped segments 10 are detachably connected. For example... Figure 3 As shown, each ring assembly 1 is divided into four arc-shaped segments 10 along its circumference. Each arc-shaped segment 10 includes a first ring segment 11 and a second ring segment 12. The first ring segment 11 and the second ring segment 12 are both quarter-circle arcs, so that they can be assembled into a ring-shaped first ring unit and a ring-shaped second ring unit, thereby forming a ring-shaped ring assembly 1.

[0042] If the hoop assembly 1 is a one-piece circular structure, then when installing the hoop assembly 1, the only installation method is to insert the reinforcing cage 4 into the hoop assembly 1. This method is extremely inconvenient when the reinforcing cage 4 is long. Therefore, in this embodiment, the hoop assembly 1 is divided into at least two segments along the circumference of the hoop assembly 1. This allows for the installation method of first attaching the arc-shaped segments 10 to the outside of the reinforcing cage 4 and then connecting the arc-shaped segments 10 to form the hoop assembly 1. Similarly, when it is necessary to remove the hoop assembly 1, the connection between each arc-shaped segment 10 and the connection between the arc-shaped segments 10 and the longitudinal reinforcement 41 are released, and each arc-shaped segment 10 can be directly removed from the side of the reinforcing cage 4, thereby greatly improving the disassembly and assembly efficiency of this embodiment.

[0043] In optional embodiments, the detachable connection method between two adjacent ring assemblies 1 includes, but is not limited to, threaded connection, flange connection or snap-fit ​​connection.

[0044] In optional implementations, such as Figure 5 As shown, each end of the arc-shaped segment 10 is provided with a connecting ear plate 123, and the connecting ear plates 123 of two adjacent arc-shaped segments 10 are connected to each other by threaded connectors.

[0045] This embodiment can ensure reliable connection between two adjacent arc segments 10 through mature threaded connectors, and also allows workers to easily separate two adjacent arc segments 10 by removing the threaded connectors.

[0046] In optional implementations, such as Figure 4 As shown, longitudinal stops 23 are provided at intervals on the longitudinal connecting rod 2. The longitudinal stops 23 abut against at least one end face of the ring assembly 1 along its axial direction, thereby restricting the relative position of the ring assembly 1 and the longitudinal connecting rod 2.

[0047] This embodiment can prevent the hoop assembly 1 from shifting relative to the longitudinal connecting rod 2 along its axial direction, thereby causing the stress distribution in the steel cage 4 to deviate from the design state and thus increasing the risk of damage to the glass fiber reinforcement.

[0048] In optional embodiments, the specific structure of the longitudinal stop 23 includes, but is not limited to, a baffle, a shoulder, a block, or an elastic retaining ring, and the connection method between the longitudinal stop 23 and the longitudinal connecting rod 2 includes, but is not limited to, a welded connection or a detachable connection, as long as the longitudinal stop 23 can limit the position of the hoop assembly 1 on the longitudinal connecting rod 2.

[0049] In an optional embodiment, semi-circular slots are provided on both opposite sides of the first gripper 111 and the second gripper 121, so that... Figure 6 As shown, the first gripper 111 and the second gripper 121 approach each other so that the semi-circular slots can be assembled into a circular slot, and the diameter of the circular slot matches the diameter of the longitudinal rib 41.

[0050] This embodiment enables the first clamp 111 and the second clamp 121 to clamp the longitudinal reinforcement 41 more securely, thereby improving the reliability of the connection between this embodiment and the steel cage 4.

[0051] In an optional embodiment, the number of first grippers 111 is at least two, and the first grippers 111 are distributed at intervals along the circumference of the first ring unit; the number and distribution spacing of the second grippers 121 match the number and distribution spacing of the first grippers 111.

[0052] This embodiment can simultaneously clamp at least two longitudinal bars 41 through the cooperation of multiple first clamps 111 and second clamps 121, thereby improving the reliability of the connection between this embodiment and the steel cage 4.

[0053] The above content is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
