Abstract

Technical Field
[0001] This utility model relates to the field of building construction technology, specifically to a stirrup device for pier construction. Background Technology
[0002] In the construction industry, the pile cap, as a key structural component connecting the superstructure and the foundation, plays a crucial role in this process. It not only effectively transfers the load from the superstructure to the foundation piles but also connects closely with the raft foundation and structural columns, ensuring the stability and safety of the overall structure. Depending on different structural design requirements, pile caps come in various forms, including single-pile, double-pile, and multi-pile pile caps.
[0003] In the construction of non-pile foundations, the construction process for the pile cap includes multiple stages such as pile cap excavation, bedding layer laying, brick formwork construction, plastering of the inner wall of the brick formwork, waterproof membrane laying, pile cap reinforcement binding, pile cap concrete pouring, and curing. For pile foundations, the construction process requires pile construction and testing before pile cap excavation, and pile head removal after pile cap excavation; the remaining procedures are the same as for non-pile foundations. Although the construction processes differ between the two foundation types, the techniques used in the pile cap construction stage are identical.
[0004] However, as the height of the foundation increases, construction workers face increasing difficulties when moving up and down the brick formwork. Especially during the construction stages of brick formwork masonry, plastering the inner wall of the brick formwork, and rebar tying, the dense arrangement of the surrounding raft slab rebar and the large number of rebar ends anchored into the foundation further restrict the safe working space for construction workers, making this stage a high-incidence period for safety accidents.
[0005] To address the challenges faced by construction workers when moving between foundations or spans of varying heights, the current construction industry commonly uses on-site fabricated wooden inclined ladders as an auxiliary tool. However, these inclined ladders have several drawbacks:
[0006] Insufficient material strength and safety performance: Since the inclined ladder is temporarily processed on site, the strength and wear resistance of the selected materials often cannot be effectively guaranteed, posing a significant safety hazard.
[0007] Lack of safety protection measures: The inclined ladder lacks necessary safety protection measures. If the structure is unstable or collapses, construction workers are very likely to fall and come into contact with the exposed steel bars, causing serious safety accidents.
[0008] High cost and low efficiency: When there are many sizes of foundations, different models of inclined ladders need to be made according to foundations of different depths. This not only increases labor and time costs, but also reduces construction efficiency.
[0009] In view of the aforementioned problems, how to provide a solution that can quickly, safely, and conveniently assist construction workers in ascending and descending the foundation for operations has become the focus of this patent research. Through technological innovation, the aim is to overcome the shortcomings of existing technologies and improve the safety and efficiency of foundation construction. Utility Model Content
[0010] In order to overcome the shortcomings of the prior art, this application provides a stirrup device for pier cap construction, which aims to overcome the shortcomings of the prior art and improve the safety and efficiency of pier cap construction.
[0011] The technical means adopted by this utility model to solve its technical problem is: a stirrup device for pier construction, the improvement of which includes:
[0012] The steel plate laying structure uses steel plates with a thickness of not less than 5mm to be laid continuously at both ends of the foundation. The steel plates allow workers to walk to the middle of the foundation to avoid the exposed steel bars anchored into the foundation around the perimeter.
[0013] The guardrail structure is installed on both sides of the steel plate paving structure and has a height of not less than 1.2m;
[0014] The structure features a ladder system, with standardized ladders made of square tubing installed on both sides of the foundation pit, and the ladders on both sides are staggered.
[0015] The outrigger structure is located on both sides of the steel plate paving structure and symmetrically arranged on both sides of the ladder structure, and is used to balance the stirrup device.
[0016] The telescopic structure includes a square steel plate with a thickness of not less than 5mm, which is nested on the steel plate laying structure and fixed with bolts, and can expand and contract to adapt to the size of the pier.
[0017] The tail of the outrigger structure described in the above technical solution is foldable.
[0018] The folding part at the tail of the outrigger structure described in the above technical solution is connected by a high-strength hinge. The hinge has a load-bearing capacity of not less than 500 kg and is equipped with a limit device to prevent the outrigger from being over-folded.
[0019] The nested portion of the telescopic structure and the steel plate laying structure in the above technical solution is provided with a guide structure.

[0021] The telescopic structure described above has multiple bolt holes on its square steel plate, with a bolt hole spacing of 50-100mm.
[0022] The guardrail structure described in the above technical solution consists of multiple vertical railings and horizontal railings. The vertical railings are spaced apart, and the horizontal railings connect adjacent vertical railings to form a closed or semi-closed structure. At least one horizontal railing is equipped with a safety net or handrail.
[0023] The steps of the ladder structure described in the above technical solution are made of anti-slip material, and anti-slip strips or anti-slip grooves are provided between the steps.
[0024] The beneficial effects of this utility model are:
[0025] This structure effectively solves the safety problems faced by workers when working on upper and lower foundations or at different heights. It fully considers the actual situation of different foundation sizes and has a high degree of adaptability. By adopting a telescopic design, the practicality of the stirrups is significantly improved, and it can flexibly adapt to various working scenarios.

Attached Figure Description
[0026] Figure 1 This is a schematic diagram of the structure of a stirrup device for pier operation, as shown in an embodiment of the present invention. Detailed Implementation
[0027] The present invention will be further described below with reference to the accompanying drawings and embodiments.
[0028] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.
[0029] like Figure 1 As shown, this application provides a stirrup device for pier construction, comprising:
[0030] Steel plate laying structure 1, using steel plates with a thickness of not less than 5mm, is laid continuously at both ends of the foundation. The steel plates allow workers to walk to the middle of the foundation to avoid the exposed reinforcing bars anchored into the foundation around the perimeter.
[0031] The guardrail structure 2 is installed on both sides of the steel plate paving structure 1 and has a height of not less than 1.2m;
[0032] Ladder structure 3: Standardized ladders made of square tubing are installed on both sides of the foundation pit, and the ladders on both sides are staggered.
[0033] Support leg structure 4, the support leg structure is arranged on both sides of the steel plate laying structure and symmetrically arranged on both sides of the climbing structure, and is used to balance the stirrup device;
[0034] The telescopic structure 5 includes a square steel plate with a thickness of not less than 5mm. The square steel plate is nested on the steel plate laying structure and fixed with bolts, and can expand and contract according to the size of the pier.
[0035] In one possible implementation, the surface of the steel plate of the steel plate laying structure 1 is provided with anti-slip texture.
[0036] Anti-slip texture can significantly increase the coefficient of friction of the steel plate surface, preventing workers from slipping and falling during walking or working. It can effectively improve the safety of the work area, especially in adverse environments such as wet, oily or muddy conditions.
[0037] In one possible implementation, the guardrail structure 2 consists of multiple vertical railings 21 and horizontal railings 22. The vertical railings 21 are spaced apart, and the horizontal railings 22 connect adjacent vertical railings 21 to form a closed or semi-closed structure. At least one horizontal railing 22 is equipped with a safety net or handrail.
[0038] Safety nets or handrails provide additional safety for workers. Safety nets can cushion and intercept when people accidentally slip, while handrails help workers maintain stability when moving or working, reducing the safety risks caused by loss of balance.
[0039] In one possible implementation, the steps 31 of the ladder structure 3 are made of anti-slip material, and anti-slip strips or anti-slip grooves are provided between the steps.
[0040] The design of anti-slip materials and anti-slip strips / grooves can significantly increase the friction of the step surface, preventing workers from slipping and falling when climbing up and down ladders. This not only improves safety but also enhances the user experience. In situations where frequent climbing is required, anti-slip steps can reduce fatigue, allowing workers to complete tasks more easily.
[0041] In one possible implementation, the tail of the outrigger structure 4 is foldable.
[0042] By using folding outriggers, the overall support strength can be ensured even in situations where the stirrups are too long and therefore insufficient. When needed, the outriggers can be unfolded and set up, and when not needed, they can be folded and locked to the underside of the stirrups.
[0043] In another possible implementation, the leg structure 4 can be a telescopic tube, which is fixed by elastic protrusions on the telescopic tube and holes on the leg structure, thereby adapting to different heights.
[0044] like Figure 1 As shown, the folding part 41 at the tail of the support leg structure 4 is connected by a high-strength hinge. The hinge has a load-bearing capacity of not less than 500 kg and is equipped with a limit device to prevent the support leg from being over-folded.
[0045] The use of high-strength hinges ensures the stability and load-bearing capacity of the outrigger structure in the unfolded state, enabling the outriggers to withstand large vertical and lateral loads and ensuring the safety and reliability of the entire stirrup device during use. The design of the folding part allows the outrigger structure to be easily folded up when not in use, greatly reducing the size and space occupied by the device, making it easy to store and transport.
[0046] In one possible implementation, the nested portion of the telescopic structure 5 and the steel plate laying structure 1 is provided with a guide structure.
[0047] Optionally, the guide structure may be a slide rail provided on the steel plate laying structure 1 and a pulley or slider provided on the lower part of the square tube steel plate of the telescopic structure 5, with the pulley or slider sliding along the slide rail.
[0048] By setting a guide structure, the telescopic structure 5 can easily move or extend on the steel plate laying structure as needed, thereby adapting to different operating scenarios and size requirements; the pulleys or sliders slide along the slide rails, reducing friction and wear between the telescopic structure and the steel plate laying structure, while ensuring smooth and seamless extension and retraction.
[0049] In one possible implementation, the telescopic structure 5 has a plurality of bolt holes 51 on its square tube steel plate, with a spacing of 50-100mm between the bolt holes 51.
[0050] The design with multiple bolt holes allows the expansion joint to be connected to other components or structural parts in a variety of ways, thus providing greater connection flexibility and adaptability; the reasonable setting of the bolt hole spacing ensures that the appropriate bolt position and number can be selected in different application scenarios to meet specific connection requirements.
[0051] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
