Description

Technical Field

[0001] This utility model belongs to the field of prefabricated underground structure engineering, specifically relating to a recyclable and reusable detachable steel mesh structure. Background Technology

[0002] Currently, as urban development goals shift from above-ground to underground, underground structures and above-ground structures differ fundamentally from both an engineering environment and construction technology perspective. Relatively speaking, underground structures face more constraints, are subject to more complex stresses, and are more difficult to construct.

[0003] The fabrication speed of steel mesh belts has a significant impact on project progress and safety, and the construction speed is often limited by the welding of steel bars to the steel mesh belt. Due to the limitations of construction space and precision, the process involves high labor input, poor working environment, low construction efficiency, waste of a large amount of materials, high raw material costs, non-standard welding quality, and a large area occupied by the work site.

[0004] Traditional steel mesh belts involve directly welding reinforcing bars to steel strips. This welding process often results in uneven distribution, inconsistent density, and low precision, causing inconvenience for on-site installation and fixing of the reinforcing bars, thus reducing overall connection efficiency. Furthermore, the steel mesh belt cannot be removed during on-site installation; it must be installed together with the reinforcing bars, making it non-recyclable and wasting a significant amount of material. Summary of the Invention

[0005] This utility model is proposed to solve the problems existing in the prior art, and its purpose is to provide a recyclable and reusable detachable steel mesh belt structure.

[0006] The technical solution of this utility model is: a recyclable and reusable detachable steel mesh belt structure, including a steel strip, the steel strip being long and strip-shaped, with a right-angled U-shaped buckle at the upper end of the steel strip, the right-angled U-shaped buckle supporting and accommodating the reinforcing bars placed therein, and a fastener for detachment and installation provided at the free end of the right-angled U-shaped buckle, the fastener for detachment and installation locking the reinforcing bars.

[0007] Furthermore, the steel strips are multiple parallel strips, and the right-angled U-shaped buckles are aligned and arranged at the upper end of the steel strips.

[0008] Furthermore, the right-angle U-shaped buckle includes a right-angle U-shaped steel rod, the back side of which is fixed to a steel strip.

[0009] Furthermore, the back side of the right-angled U-shaped steel rod forms a plane that contacts the surface of the steel strip, and the right-angled U-shaped steel rod and steel strip are welded and fixed.

[0010] Furthermore, the right-angled U-shaped steel rod includes two threaded rods, the threaded section of which is a free end.

[0011] Furthermore, the spacing between the threaded rods is slightly larger than the outer diameter of the reinforcing bar, thereby enabling the reinforcing bar to be placed between the threaded rods.

[0012] Furthermore, the fastener includes a reinforcing bar washer, in which a through hole corresponding to the threaded rod is formed, and the threaded rod passes through the through hole.

[0013] Furthermore, the axis of the threaded rod is perpendicular to the upper end of the steel strip.

[0014] Furthermore, the long side of the steel strip is spatially perpendicular to the axial direction of the reinforcing bar.

[0015] The beneficial effects of this utility model are as follows:

[0016] This invention eliminates the need for direct welding of reinforcing bars to the steel strip by adding a right-angled U-shaped buckle, thus avoiding material waste. The welding cost of a single new steel mesh strip is almost the same as that of a traditional steel mesh strip, and considering that the steel strip can be recycled, the cost can be greatly reduced.

[0017] This invention uses a welded right-angle U-shaped clip instead of direct welding to the reinforcing bar, which allows for precise control of the welding accuracy and ensures the density of multiple welded joints. After welding, the reinforcing bar can also be rolled up along the direction of the steel strip for subsequent transportation. Attached Figure Description

[0025] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:

[0026] like Figures 1 to 3As shown, a recyclable and reusable detachable steel mesh belt structure includes a steel strip 1, which is a long strip. The upper end of the steel strip 1 is provided with a right-angled U-shaped buckle 2, which supports and accommodates the reinforcing bar 3 placed therein. The free end of the right-angled U-shaped buckle 2 is provided with a fastener for locking the reinforcing bar 3.

[0027] The steel strip 1 consists of multiple parallel strips, and the right-angled U-shaped buckles 2 are aligned and arranged on the upper end of the steel strip 1.

[0028] The right-angle U-shaped buckle 2 includes a right-angle U-shaped steel rod 4, the back side of which is fixed to the steel strip 1.

[0029] The back side of the right-angled U-shaped steel rod 4 forms a plane that contacts the surface of the steel strip 1, and the right-angled U-shaped steel rod 4 and the steel strip 1 are welded and fixed.

[0030] The right-angled U-shaped steel rod 4 includes two threaded rods, and the threaded section of the threaded rod is a free end.

[0031] The spacing between the threaded rods is slightly larger than the outer diameter of the reinforcing bar 3, so that the reinforcing bar 3 can be placed between the threaded rods.

[0032] The fasteners for disassembly and assembly include a steel bar washer 5, in which a through hole corresponding to the threaded rod is formed, and the threaded rod passes through the through hole.

[0033] The axis of the threaded rod is perpendicular to the upper end of the steel strip 1.

[0034] The long side of the steel strip 1 is spatially perpendicular to the axial direction of the reinforcing bar 3.

[0035] Specifically, the fasteners also include nut washers 6 and nuts 7, which are installed on the threaded section of the threaded rod, so as to press down the reinforcing bar washer 5 from top to bottom, and fasten the reinforcing bars 3 between the threaded rods through the reinforcing bar washer 5.

[0036] Specifically, an arc-shaped connection is formed between the threaded rods, and the arc-shaped connection is adapted to the outer diameter of the reinforcing bar 3.

[0037] Specifically, such as Figures 1 to 3 As shown, each steel strip 1 is equipped with five right-angled U-shaped buckles 2.

[0038] Specifically, the steel strip 1 and the right-angled U-shaped steel rod 4 are fixed by welding, and the steel strip 1 can be rolled up for transportation, reducing the space occupied and facilitating the overall transportation after processing.

[0039] Specifically, the reinforcing bar 3 passes directly through the middle of the right-angled U-shaped steel rod 4 and extends a certain length so that it can be clamped by the reinforcing bar washer 5, a nut washer 6 is inserted, and the nut 7 is tightened to completely fix the reinforcing bar 3 to the right-angled U-shaped clip 2. After the fixed reinforcing bar 3 is transported to the site for installation, the right-angled U-shaped clip 2 can be opened, and the steel strip 1 and the right-angled U-shaped clip 2 can be removed for reuse and connection to the next batch of reinforcing bars 3.

[0040] Specifically, the right-angle U-shaped buckle 2 is directly welded to the steel strip 1, ensuring the accuracy of the distance between the right-angle U-shaped buckles 2, which in turn ensures the accuracy of the distance between all the reinforcing bars 3, indirectly improving the quality control level of the reinforcing mesh.

[0041] Specifically, the steel strip 1 and the reinforcing bar 3 do not need to be directly connected, which significantly improves the connection effect, greatly increases the installation accuracy, ensures the consistency of the spacing of the connecting reinforcing bars, greatly reduces manufacturing costs, and significantly reduces the space occupied during transportation.

[0042] This invention ensures the accuracy of the installation angle between steel bars upon arrival at the site, which can speed up the installation of steel bars on site and improve the installation quality.

[0043] The processing and use of this utility model are as follows:

[0044] This embodiment provides a recyclable and reusable detachable steel mesh belt structure, including the following steps:

[0045] A. In-factory processing

[0046] a1. Referring to the design drawings, weld the right-angled U-shaped buckle 2 to the steel strip 1 according to the required distance between the reinforcing bars;

[0047] a2. Open nut 7, remove nut washer 6 and rebar washer 5, put rebar 3 into the hole and extend it a certain distance, put in rebar washer 5 and nut washer 6, and tighten nut 7;

[0048] a3. Roll up the steel mesh belt along the direction of steel strip 1 for transportation.

[0049] B. On-site installation

[0050] b1. Remove the steel mesh belt and unfold it along the direction of steel strip 1;

[0051] b2. Connect the steel bar 3 on the steel mesh strip to the on-site steel bars;

[0052] b3. Open nut 7, remove nut washer 6 and rebar washer 5, and separate rebar 3 from the remaining part of the steel mesh belt;

[0053] b4. Remove the remaining portion of the steel mesh belt for recycling.

[0054] This invention eliminates the need for direct welding of reinforcing bars to the steel strip by adding a right-angled U-shaped buckle, thus avoiding material waste. The welding cost of a single new steel mesh strip is almost the same as that of a traditional steel mesh strip, and considering that the steel strip can be recycled, the cost can be greatly reduced.

[0055] This invention uses a welded right-angle U-shaped clip instead of direct welding to the reinforcing bar, which allows for precise control of the welding accuracy and ensures the density of multiple welded joints. After welding, the reinforcing bar can also be rolled up along the direction of the steel strip for subsequent transportation.
