Abstract

The utility model relates to the technical field of reinforcement cage supporting, in particular to a detachable temporary supporting rod device which comprises a limiting ring. The limiting ring is adjustably connected with a plurality of supporting rods; a plurality of first limiting holes are distributed in the limiting ring, and the limiting ring is detachably connected with a supporting rod; the supporting rod is detachably connected with a clamping piece. The limiting ring provided with the twelve first limiting holes can be selectively connected with three or four or six supporting rods according to reinforcement cages with different inner diameters, and therefore the reinforcement cages can be stably supported in a matched mode. And the supporting rods are detachably connected to the limiting rings, so that the supporting rods are convenient to mount and dismount. Due to the design that the external thread structures and the screw rod structures of the clamping pieces are arranged at the two ends of the supporting rods correspondingly, the supporting rods can be detachably connected to the limiting sleeves, the length of the whole supporting rod device can be adjusted within a certain range, and therefore reinforcement cages with different diameters can be supported; the application range of the supporting rod device is expanded due to the adjustability of the supporting rod device.

Description

Technical Field

[0001] The utility model relates to the technical field of steel cage support, and more specifically, to a detachable temporary support rod device. Background Art

[0002] During transportation and hoisting, rebar cages are prone to deformation, impacting their quality. A rebar cage support frame is a structure that supports the cage skeleton during hoisting and transportation in construction projects, preventing deformation. Existing technology typically uses cross-bracing rods welded directly to the inside of the cage to support and secure it.

[0003] Patent publication number CN217299495U discloses a steel cage support frame. The relative positions of the support and length adjustment rods are adjusted by fitting them together. One end of the threaded adjustment rod is threadedly connected to the end of the length adjustment rod that is farther away from the support rod, while the other end is provided with a connecting clip for engaging the steel cage. By rotating the threaded adjustment rod, the distance between the steel cage support frame and the cage can be further adjusted, while the connecting clip fits snugly with the cage. However, for steel cages with larger inner diameters, using four supports may not provide sufficient support, potentially causing the cage to deform. For steel cages with smaller inner diameters, using four supports may waste some supporting material. Consequently, the aforementioned support frame suffers from poor adjustability and a limited scope of application. Utility Model Content

[0006] The limiting ring is provided with a plurality of first limiting holes and is detachably connected to the support rod;

[0007] The support rod is detachably connected with a clamp.

[0008] Furthermore, the limiting ring is evenly distributed with twelve first limiting holes, and the central axes of the first limiting holes intersect at the center point of the limiting ring;

[0009] The support rods are connected to three, four or six of the first limiting holes which are centrally symmetrical to each other, so as to support the steel cage.

[0010] Furthermore, the limiting ring is provided with a limiting sleeve, and the limiting sleeve includes an arc-shaped sleeve sleeved on the limiting ring and a first connecting sleeve fixedly connected to the arc-shaped sleeve.

[0011] Furthermore, the curvature of the arc-shaped sleeve matches the curvature of the limiting ring.

[0012] Furthermore, a second limiting hole is formed on the arc-shaped sleeve toward the center of the limiting ring, and a bolt is passed through the second limiting hole and the first limiting hole to fix the arc-shaped sleeve to the limiting ring.

[0013] Furthermore, both ends of the support rod are respectively provided with threads, one end is threadedly connected to the first connecting sleeve, and the other end is threadedly connected to the second connecting sleeve, and the second connecting sleeve is threadedly connected to the clamp.

[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0035] Example 1:

[0036] like Figure 1-Figure 7As shown, this embodiment provides a detachable temporary support rod device, including a limiting ring 1, the limiting ring 1 is provided with a plurality of first limiting holes 11, the limiting ring 1 is adjustably connected to a plurality of support rods 2, and each support rod is detachably connected to the limiting ring 1; the support rod 1 is detachably connected to a clamp 3, and the clamp 3 is used to abut the steel bars of the steel cage, thereby achieving a supporting effect on the steel cage.

[0037] In this embodiment, Figure 4 and Figure 5 As shown, the limiting ring 1 has twelve evenly distributed first limiting holes 11, and the central axes of the first limiting holes 11 intersect at the center point of the limiting ring 1; three, four or six first limiting holes 11 that are centrally symmetrical are connected with support rods 2, thereby used to support the steel cage.

[0038] When three of the evenly spaced first limiting holes are connected with support rods, as shown in FIG. Figure 2 As shown, three support rods are arranged for support, which can support the steel cage with a slightly smaller inner diameter, without wasting the raw materials of the support rods and achieving stable support for the steel cage.

[0039] When four of the first limiting holes are connected with support rods, Figure 1 As shown, four support rods are arranged to support the steel cage, so that the steel cage can be stably transported, hoisted and arranged.

[0040] When six of the first limiting holes are connected with support rods, Figure 3 As shown, six support rods are arranged to support the steel cage, which is suitable for supporting steel cages with slightly larger inner diameters, so that the steel cage can be stably transported, hoisted and arranged.

[0041] In this embodiment, the limiting ring 1 is provided with six limiting sleeves 12, each comprising an arcuate sleeve 121 that is sleeved on the limiting ring 1 and a first connecting sleeve 122 that is fixedly connected to the arcuate sleeve 121. The curvature of the arcuate sleeve 121 matches that of the limiting ring 1, allowing the arcuate sleeve 121 to slide along the limiting ring. Twelve first limiting holes 11 are provided on the limiting ring 1 to provide uniform support for three, four, or six support rods, respectively. Since a maximum of six support rods are provided, the number of limiting sleeves 12 is designed to be six.

[0042] Specifically, if Figure 6 and Figure 7 As shown, a second limiting hole 123 is opened on the arc sleeve 121 toward the center side of the limiting ring 1, and a bolt 4 is used to pass through the second limiting hole 123 and the first limiting hole 11 to fix the arc sleeve 121 to a specific first limiting hole 11 of the limiting ring 1, so as to facilitate the subsequent connection of the support rod.

[0043] In this embodiment, the support rod 2 is made of a steel pipe, and threads are provided at both ends thereof. One end of the support rod is threadedly connected to the first connecting sleeve 122, and the other end is threadedly connected to the second connecting sleeve 5, and the second connecting sleeve 5 is threadedly connected to the clamp 3.

[0044] Specifically, the clamp 3 includes a screw 31 and an arc-shaped bayonet 32 ​​fixed to each other. The arc-shaped bayonet 32 ​​is a steel plate bent into an arc shape. The arc-shaped bayonet 32 ​​is used to abut against the steel bars of the steel cage. The screw 31 is threadedly connected to the second connecting sleeve 5. The first connecting sleeve 122 and the second connecting sleeve 5 are both provided with internal threads.

[0045] It is worth noting that the threads on the end of the support rod 2 near the second connecting sleeve 5 are in the opposite direction to the threads of the screw 31. In this way, when the second connecting sleeve 5 is rotated, the support rod 2 and the screw 31 can be moved closer to or away from each other. At the same time, due to the arrangement of the first connecting sleeve 122 and the second connecting sleeve 5, as well as the threaded structure at both ends of the support rod, combined with the threaded structure of the screw of the clamp 3, the length of the entire support rod device can be adjusted within a certain distance range, thereby enabling adaptive support of steel cages with a certain diameter range.

[0046] The detachable temporary support rod device provided in this embodiment utilizes a limiting ring 1 provided with twelve first limiting holes 11, and can selectively connect three, four or six support rods 2 according to different inner diameters of steel cages, thereby adaptively providing stable support for the steel cages. The support rods 2 are detachably connected and arranged on the limiting ring 1, which facilitates the installation and removal of the support rods. Since the two ends of the support rod 2 are respectively provided with an external thread structure and a screw structure design of a clamp, the support rod can not only be detachably connected to the limiting sleeve, but also can adjust the length of the overall support rod device within a certain range, thereby being able to support steel cages of different diameters. The adjustability of the support rod device expands its scope of application.

[0047] Example 2:

[0048] This embodiment further comprises an extension section 6 based on the first embodiment. The extension section 6 is made of a steel pipe, and threads are arranged at both ends thereof.

[0049] like Figure 8 and Figure 9 As shown, the extension section 6 is threadedly connected to the end of the support rod 2 through a second connecting sleeve 5, and the other end of the extension section 6 is connected to the clamp 3 through another second connecting sleeve 5. The arrangement of the extension section further expands the scope of application of the device and can be applied to steel cages with larger diameters.

[0050] Finally, it should be noted that the above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art will be able to modify the technical solutions described in the aforementioned embodiments or replace some of the technical features therein with equivalents. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention shall be included within the scope of protection of the present invention.
