Description

Technical Field

[0001] This utility model relates to the fields of civil engineering and steel structure building technology, specifically a recyclable floor deck combined with steel beam support device. Background Technology

[0002] In modern steel structure building construction, the combination of composite steel beams and floor decking is increasingly widely used. This structural form not only improves the overall strength and stability of the building but also accelerates the construction progress and reduces costs. However, in actual construction, the construction problems at the joint between the composite steel beams and floor decking have always been one of the difficulties restricting construction efficiency and quality.

[0003] Specifically, during the pouring of concrete together with the composite steel beams and floor slabs, special treatment is required at the connection points to ensure the structural integrity. Since traditional wooden formwork support systems cannot be used at this location, 2.0mm thick Z-shaped side formwork is commonly employed as the side formwork in engineering projects. However, Z-shaped side formwork presents the following problems in practical applications: Formwork bulging: During concrete pouring, the lateral pressure of the concrete on the side formwork is significant. Z-shaped side formwork often struggles to withstand this pressure, causing the formwork to expand outwards, a phenomenon known as "formwork bulging." Formwork bulging not only affects the dimensional accuracy and appearance quality of concrete components but can also lead to concrete leakage in severe cases, impacting the overall performance of the structure.

[0004] Unstable support issue: To pour concrete, holes need to be drilled in the bottom formwork of the floor slab so that the concrete can flow smoothly into the gap between the steel beam and the floor slab. However, this operation causes the bottom formwork of the floor slab to only act on the upper end of the Z-shaped side formwork, losing its original full support. As a result, the floor slab is prone to sinking or deformation during the concrete pouring process, affecting construction safety and project quality.

[0005] Currently, there are no publicly available and effective solutions to the above problems. Traditional support methods often struggle to simultaneously address the two major challenges of formwork bulging and support instability, leading to frequent adjustments and reinforcements of the support system during construction, which increases construction difficulty and costs. Utility Model Content

[0006] This utility model aims to overcome the defects of the prior art and provide a recyclable floor deck combined steel beam support device to solve the problems of concrete bulging during Z-shaped side formwork pouring of steel beams and unstable floor deck lap support.

[0007] To solve the above-mentioned technical problems, this utility model is implemented as follows: A recyclable floor decking combined with steel beam support device is disclosed. The device has an overall "U" shaped structure and mainly consists of a base, vertical supports, diagonal supports, fixing bolts, and horizontal supports forming the lower support structure. The vertical and diagonal supports are welded together and then welded to the base for fixation. Two bolt holes are provided on the base, corresponding to the width of the lower flange of the steel beam, for use with fixing bolts to secure the lower support structure to the steel beam. The horizontal supports are erected on top of the vertical supports.

[0008] Furthermore, the angle formed between the vertical and diagonal supports is 45°-60°. This angle design allows the support structure to better adapt to the mechanical requirements of different construction scenarios while ensuring stability, thus improving the versatility and applicability of the device.

[0009] Furthermore, the base is made of channel steel, while the vertical and diagonal supports are made of angle steel. This choice of steel not only ensures the strength and stability of the support structure but also facilitates processing and installation, reducing production costs and improving construction efficiency.

[0010] Furthermore, the device can be dismantled by unscrewing the fixing bolts after the concrete pouring is completed, enabling its recycling. This design allows the device to be easily disassembled and reused after construction, reducing construction waste, aligning with the concept of sustainable development, and also lowering construction costs.

[0011] Furthermore, the length of the horizontal support is 500mm-800mm. This length range ensures that the horizontal support can effectively provide support in different construction scenarios, while also guaranteeing the overall stability and reliability of the device.

[0012] The beneficial effects of this utility model are as follows: As can be seen from the above technical solution, this application provides a recyclable floor deck composite steel beam support device. By setting a "U"-shaped support device at the bottom of the composite steel beam, the synergistic effect of vertical, diagonal, and horizontal supports provides a stable support structure for the Z-shaped side formwork of the steel beam. This structural design effectively avoids the bulging phenomenon caused by lateral pressure during concrete pouring, ensuring the quality of concrete forming and reducing structural defects and rework risks caused by bulging.

[0013] The device uses channel steel as the base and angle steel as vertical and diagonal supports. These steel materials possess high strength and excellent resistance to deformation. Simultaneously, the vertical and diagonal supports form an angle of 45°-60°, an angle optimized for mechanical properties to effectively disperse and transfer the lateral pressure generated during concrete pouring, making the entire support system more stable. Furthermore, the rational arrangement of the horizontal supports further enhances the device's lateral stability, ensuring the stability of the lower supports even after openings in the floor slab's bottom membrane, preventing structural deformation due to insufficient support.

[0014] After the concrete is poured, the device can be quickly dismantled by unscrewing the fixing bolts, and all components are reusable. This recyclable design not only reduces construction waste and environmental impact but also significantly lowers construction costs. Compared to traditional disposable support materials, the recyclability of this device offers significant economic advantages, making it particularly suitable for large-scale steel structure construction projects.

[0015] Furthermore, the standardized design of the device allows it to adapt to various specifications of steel beams and floor slabs, reducing on-site adjustment and processing time and further improving construction efficiency. The rapid dismantling of the device after concrete pouring also facilitates subsequent construction procedures. Attached Figure Description

The horizontal supports are erected on top of the vertical supports.

[0021] Furthermore, the angle formed between the vertical and diagonal supports is 45°-60°. This angle design allows the support structure to better adapt to the mechanical requirements of different construction scenarios while ensuring stability, thus improving the versatility and applicability of the device.

[0022] Furthermore, the base is made of channel steel, while the vertical and diagonal supports are made of angle steel.

[0023] Furthermore, the device can be dismantled by unscrewing the fixing bolts after the concrete pouring is completed, enabling its recycling. This design allows the device to be easily disassembled and reused after construction, reducing construction waste, aligning with the concept of sustainable development, and also lowering construction costs.

[0024] Furthermore, the length of the horizontal support is 500mm-800mm. This length range ensures that the horizontal support can effectively provide support in different construction scenarios, while also guaranteeing the overall stability and reliability of the device.

[0025] The installation method is as follows: Ground assembly: On the ground, assemble the base 1.1, vertical support 1.2.1, diagonal support 1.2.2 and horizontal support 1.4 to form the lower support structure.

[0026] Preliminary fixing: Place the assembled lower support structure under the steel beam and use fixing bolts 1.3 to fix it to the steel beam through the bolt holes on the base 1.1. The fixing interval is 800-1000mm.

[0027] Spacing adjustment: Adjust the spacing between vertical support 1.2.1 and Z-shaped side mold 2 to 50mm to ensure that horizontal support 1.4 can pass through smoothly and be erected on vertical support 1.2.1.

[0028] Fastening system: Tighten 1.3 bolts to form a stable support system for the 4-combination steel beam nodes of the floor deck.

[0029] Example 2 Welding assembly: Base processing: On the base channel steel, two bolt holes with a diameter of φ17mm are centered according to the width of the lower flange of the steel beam for installing fixing bolts.

[0030] Welding of vertical and diagonal supports: The vertical and diagonal supports are welded together to form an "L"-shaped structure. During welding, ensure that the included angle between the vertical and diagonal supports is 50° (within the optimized range of 45°-60°h).

[0031] Overall welding: The pre-welded vertical and diagonal supports are welded to the base to form a "U"-shaped support structure. During the welding process, ensure welding quality and avoid incomplete or missed welds.

[0032] Horizontal support installation: Weld the horizontal support to the upper part of the vertical support to ensure a firm and reliable connection between the horizontal and vertical supports.

[0033] like Figure 2 As shown: Installation of I-beam 3.1 and shear studs 3.2 Placement of the I-beam: Place the I-beam above the support device, ensuring that the web of the I-beam is aligned with the vertical support (1.2.1) of the support device.

[0034] Fixing the I-beam: The I-beam is fixed to the support device using fixing bolts (1.3). The fixing bolts pass through the flange of the I-beam and the base of the support device (1.1) and are tightened with nuts.

[0035] Positioning of studs: On the flange of the I-beam, according to the design drawings and construction requirements, use measuring tools (such as chalk lines or laser levels) to accurately locate the position of the studs.

[0036] Welding of studs: Weld the studs to the flanges of the I-beam. During welding, ensure that the studs are perpendicular to the flanges of the I-beam, and that the weld is secure, avoiding incomplete or missed welds.

[0037] On-site installation: Device positioning: Place the assembled support device under the steel beam, ensuring that the base of the device is aligned with the lower flange of the steel beam.

[0038] Initial fixing: The support device is initially fixed to the steel beam using fixing bolts. The bolt spacing is 800mm-1000mm to ensure that the device will not shift during the pouring process.

[0039] Adjust the spacing: Adjust the spacing between the vertical support and the Z-shaped side formwork to keep it at about 50mm so that the horizontal support can pass through smoothly and be erected on the vertical support.

[0040] Tighten bolts: After confirming that the device is in the correct position, tighten the fixing bolts to ensure that the support device is firmly connected to the steel beam and forms a stable support system.

[0041] Concrete pouring: After the support structure is installed, concrete is poured. During the pouring process, the construction specifications must be strictly followed to ensure that the concrete is vibrated and compacted, and to avoid bulging of the formwork due to improper vibration.

[0042] Equipment dismantling and recycling: After the concrete is poured and the concrete strength reaches the design requirements (usually above 75% of the design strength), remove the fixing bolts and detach the support device from the steel beam. After simple cleaning and inspection, the dismantled device can be reused in other construction projects, achieving recycling.
