Description

Technical Field

[0001] This utility model relates to the field of formwork reinforcement technology in building engineering, and in particular to a non-through-type steel structure formwork reinforcement structure suitable for polygonal irregular-shaped steel plate wall columns. Background Technology

[0002] In multi-faceted irregular-shaped steel plate wall-column composite structures, traditional through-bolt reinforcement methods require numerous holes to be drilled in the steel profiles. This not only damages the mechanical properties of the steel profiles and affects structural safety, but also makes it difficult to ensure the airtightness and stability of the formwork. Furthermore, the complex nodes of irregular structures make traditional reinforcement methods difficult and inefficient to implement. Therefore, there is an urgent need for a formwork reinforcement structure that does not damage the steel profiles, is easy to install, and provides reasonable stress distribution.

[0012] Compared with related technologies, the non-through-type steel structure formwork reinforcement structure provided by this utility model has the following beneficial effects:

[0013] This invention provides a non-through-type steel structure formwork reinforcement structure. By welding a fastening sleeve to the steel profile and screwing a reinforcing bolt into the internal thread of the fastening sleeve, the connection is achieved, completely avoiding drilling holes in the steel profile and maximizing the protection of the main structure's mechanical properties.

Detailed Implementation

[0018] The technical solution of this utility model will be described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the following embodiments are merely exemplary and should not be construed as limiting the scope of protection of this utility model.

[0019] Example 1

[0020] like Figures 1 to 3 As shown, the present invention provides a non-through-type steel structure template reinforcement structure, the core of which lies in a complete non-through-type force-bearing system.

[0021] First, there is the structural foundation—the steel plate wall column 100, which provides the final anchoring point for the entire reinforced structure. Surrounding the steel plate wall column 100 is a supporting frame 200 formed by reinforcing steel bars; this is the existing concrete structural component.

[0022] The irregularly shaped assembly template 300 is closely attached to the outside of the support frame 200, and its inner surface shape perfectly matches the structural outline of the steel plate wall column 100. The template consists of a support frame (such as timber or steel) and a high-strength film-coated plywood panel covering its surface, which is prefabricated into finished modules in the factory or on site.

[0023] On the outside of the irregularly shaped assembled template 300, a secondary keel 500 is fixed. In this embodiment, the secondary keel 500 is a square timber or a steel back rib, and its direction is usually perpendicular to the direction of the reinforcing screw 11, directly bearing the pressure transmitted from the template.

[0024] On the outside of the secondary keel 500, a main keel 400 is provided. In this embodiment, the main keel 400 adopts two parallel Φ48.3×3.6mm standard scaffolding steel pipes, and its function is to collect the force transmitted from the secondary keel 500 and evenly transmit it to the reinforcement module.

[0025] The most critical part is the non-through-and-through reinforcement module 1. It includes a reinforcement screw 11, a fastening sleeve 12, and a fastening unit. The fastening sleeve 12 is pre-welded firmly to the flange of the steel plate wall column 100 by full welding. The fastening sleeve 12 has internal threads machined inside.

[0026] During installation, one end of the reinforcing screw 11 is screwed into the internal thread of the fastening sleeve 12 to achieve a reliable connection. The other end of the reinforcing screw 11 passes through the gaps between the secondary keels 500 and abuts against the outside of the main keel 400 (double steel pipe). The fastening unit includes a fastening bracket 13 (a mountain-shaped bracket in this embodiment) sleeved on the reinforcing screw 11 and a fastening nut 14 screwed onto the end of the reinforcing screw 11. Tightening the fastening nut 14 so that it abuts against the end face of the fastening bracket 13 uses the lever principle to press the main keel 400 tightly onto the secondary keels 500, thereby sequentially pressing the irregularly shaped assembled template 300 and the support frame 200, ultimately forming a closed template reinforcement system based on the steel plate wall column 100. Throughout the process, the axial direction of the reinforcing screw 11 remains basically perpendicular to the reinforced surface of the steel plate wall column 100 to ensure optimal stress distribution.

[0027] Example 2

[0028] Based on Example 1, this example further discloses key technical features that ensure construction accuracy.

[0029] The welding position of the fastening sleeve 12 is predetermined before the reinforcement installation. This is achieved through a 3D information model of the steel plate wall column 100 and the supporting frame 200 reinforcement, created using BIM technology (such as Revit, Tekla, etc.). Collision detection and spatial coordination are then performed. Based on the layout drawing output from the BIM model, construction personnel precisely position and weld the fastening sleeve 12 on the steel plate wall column 100, forming the welded part 15. This ensures that all sleeves perfectly avoid the internal steel stiffening ribs and the dense reinforcement on the periphery, fundamentally avoiding conflicts such as on-site drilling and rebar cutting, achieving "zero-collision" construction.

[0030] In this embodiment, the fastening bracket 13 is specifically a mountain-shaped bracket that fits tightly with the shape of the main keel 400 (double steel pipe). This specially designed bracket can very stably hold the double steel pipe, preventing slippage during the fastening process, and ensuring effective force transmission and the stability of the entire system.

[0031] Example 3

[0032] This embodiment aims to fully disclose the collaborative relationship between its various components during dynamic construction by describing the application process of the structure.

[0033] 1. Detailed design and prefabrication: Using BIM technology, the polygonal irregular steel plate wall column 100 is designed, the module disassembly of the irregular assembly template 300 is completed, and the precise welding point diagram of the fastening sleeve 12 is generated.

[0034] 2. Welding fastening sleeve 12: After the steel structure is installed and before the reinforcing bars are tied, weld the fastening sleeve 12 to the designated position of the steel plate wall column 100 according to the location diagram.

[0035] 3. Reinforcing bar binding and formwork installation: After the reinforcing bar binding of the 200 support frame is completed and accepted, the pre-fabricated irregular-shaped assembled formwork 300 is placed in place according to the assembly sequence, and then the secondary keel 500 and the main keel 400 are installed.

[0036] 4. Installation and fastening: Screw the reinforcing screw 11 into the fastening sleeve 12, so that its other end passes through the secondary keel 500 and abuts against the main keel 400. Then put on the mountain-shaped clip (fastening clip seat 13), and finally tighten the fastening nut 14. Apply pre-tightening force with tools such as wrenches to complete the final reinforcement of the template.

[0037] 5. Concrete Pouring and Formwork Removal: During concrete pouring, the lateral pressure is ultimately transmitted to the steel plate wall column 100 through the aforementioned force path. During formwork removal, simply loosen the fastening nut 14 and remove the reinforcing bolt 11 to sequentially remove the main keel 400, secondary keel 500, and irregularly shaped assembled formwork 300. All components are reusable.

[0038] The above embodiments are merely preferred embodiments of this utility model. Any modifications, equivalent substitutions, and improvements made by those skilled in the art within the principles of this utility model should be included within the protection scope of this utility model.
