The new type of stirrup for construction is a critical supporting component in reinforced concrete work, primarily used to secure the position of upper reinforcement bars in structures such as floor slabs, raft foundations, and pile caps. It ensures that the reinforcement cover thickness meets design specifications while effectively distributing the load from the reinforcement down to the underlying structural layers, thereby maintaining the stability of the rebar framework and guaranteeing high-quality construction. This product has been rigorously developed and manufactured in accordance with GB 50204-2015, the "Code for Acceptance of Construction Quality of Concrete Structural Engineering," as well as other relevant industry standards. With its innovative structural design, outstanding mechanical performance, and convenient construction features, it is perfectly suited for a wide range of architectural projects, providing solid assurance for the safety and durability of concrete structures.

Product Advantages

1. Structural innovation, powerfully supportive

Adopting an integrated molding structural design, this product significantly enhances overall load-bearing performance compared to the traditional welded and spliced structure of conventional stirrups. Each stirrup can withstand a maximum load of up to 1200N, providing stable support for multi-layered reinforcing steel that accumulates significant loads. Additionally, an innovative triangular support force structure evenly distributes the weight of the upper reinforcement layers to the underlying framework, effectively relieving stress concentrations and preventing localized deformation or fracture of the stirrups under heavy loads. According to authoritative testing, under standard loading conditions, the product exhibits permanent deformation of no more than 0.5mm—far surpassing the industry average—and thus ensures precise positioning and secure fixation of the reinforcing bars.

2. Precise thickness control, controllable quality

The product’s high precision is strictly controlled within ±2mm, ensuring accurate alignment with the design requirements for reinforcing bar cover layers of varying thicknesses—and fundamentally addressing the issue of insufficient or excessive cover layer thickness caused by dimensional inaccuracies in traditional stirrups. The top features an arc-shaped support design that closely conforms to the rebar, preventing damage to the steel while effectively safeguarding it from shifting during construction. By using this product, the pass rate for proper rebar cover thickness can be increased to over 98%, significantly enhancing the overall quality of concrete structure construction.

3. Easy to install, saving time and effort

Manufactured using standardized specifications, the product also supports customization of special dimensions tailored to engineering requirements, making it suitable for various scenarios involving different rebar spacing and cover thicknesses. Lightweight and compact in design, these products are easy to handle and transport—no complicated tools are needed during installation. They can be securely fixed to the lower-layer reinforcement either by tying or spot welding, ensuring a simple yet highly efficient process. A skilled worker can complete the installation of 1,500 to 2,000 units per day, representing an efficiency improvement of more than 50% compared to traditional stirrup installation methods—and significantly reducing the overall construction timeline.

4. Corrosion-resistant and durable, offering excellent value for money

Utilizing high-quality materials such as HRB400E threaded steel and Q235B low-carbon steel, combined with advanced surface treatments like hot-dip galvanization and rust-removal passivation, effectively enhances the product's corrosion resistance. This ensures a service life of over 15 years even in harsh construction environments characterized by humidity and outdoor exposure. The production process is well-established, and raw material supply remains consistently reliable, enabling us to maintain superior quality while keeping production costs under control. Compared to traditional stirrups, these innovative products reduce replacement frequency by more than 60%, significantly cutting down on long-term maintenance expenses and ultimately helping to lower overall project costs.

5. Safe, environmentally friendly, and widely adaptable

The product material complies with the national environmental standards for building materials, emitting no harmful chemicals and ensuring the health of construction workers as well as environmental safety. It meets the A-grade non-combustible fire protection standard, making it suitable for high-rise buildings, underground projects, and other scenarios with stringent fire safety requirements. Additionally, the product is compatible with various rebar specifications, including HRB335, HRB400, and HRB500, and can be widely used in diverse applications such as residential buildings, industrial plants, municipal engineering projects, and more—demonstrating exceptional versatility.

Application Scenarios

1. Civil Engineering Construction Scenarios

Suitable for reinforcing steel support in residential buildings, apartments, villas, and other civil structures—including floor slabs, balconies, terraces, and bathrooms. During residential floor slab construction, the new type of stirrup precisely controls the thickness of the concrete cover over the reinforcement bars, ensuring both the load-bearing capacity and durability of the slab while preventing cracking caused by insufficient cover. In damp areas like bathrooms and balconies, the stirrups' outstanding corrosion resistance effectively safeguards structural integrity by eliminating the risk of rust-induced deterioration—making them perfectly suited to meet the stringent quality and safety standards required in residential construction.

2. Industrial Construction Project Scenarios

Suitable for raft foundations, equipment bases, roof-bearing structures, and other critical areas in industrial buildings such as factories, warehouses, and production workshops. Industrial facilities often feature heavy equipment loads and high reinforcement densities. The innovative stirrup design boasts robust load-bearing capacity, providing stable support for densely packed rebar frameworks while ensuring the structural integrity of both foundation systems and roof-bearing components. Moreover, in the challenging environments of high-temperature and humid production workshops, its exceptional corrosion resistance and durability help maintain long-term structural stability, perfectly meeting the demanding requirements for high strength and extended longevity in industrial construction.

3. Municipal and Public Works Construction Scenarios

It plays a vital role in public buildings such as municipal roads, bridges, tunnels, subway stations, stadiums, and libraries. The thickness of the concrete cover over reinforcing bars—critical for components like bridge piers and tunnel linings—must meet stringent requirements. Thanks to the precise thickness-control performance of the new stirrup design, structural integrity can reliably adhere to design standards, enhancing both the fatigue resistance and service life of bridges and tunnels. Meanwhile, in large-span structures like subway stations and stadiums, the efficient installation capabilities of this innovative solution accelerate construction timelines, while its Class A fire-resistant properties fully satisfy the rigorous fire safety standards mandated for public buildings.

4. Underground and Hydraulic Engineering Construction Scenarios

Suitable for reinforcing steel supports in underground structures such as underground parking garages, underground shopping malls, civil defense projects, reservoir dams, and sewage treatment plants. Given the damp conditions of underground environments, the rust-resistant properties of the new stirrup design effectively prevent corrosion damage, ensuring the long-term stability of underground structures. In hydraulic constructions like reservoir dams and sewage treatment plants—where reinforced steel frameworks endure heavy loads while being exposed to moist conditions—their exceptional load-bearing capacity and superior corrosion resistance guarantee stable positioning of the reinforcement bars, thereby mitigating safety risks caused by structural leaks or insufficient load-bearing capacity.
