Description

Technical Field

[0001] The utility model relates to a staircase widening structure. Background Art

[0002] In the field of stair construction and renovation, universal standard formwork (kits) are usually used for stair structure assembly and masonry. However, when the lower staircase needs to be widened and rebuilt, traditional methods often face the following challenges:

[0003] Special design requirements: Widening the lower flight of stairs requires custom-made special shaped templates to accommodate the new size and shape requirements. These special shaped templates must be precisely made to ensure a perfect fit with the existing staircase structure.

[0004] Complexity of production and installation: Customizing special-shaped formwork involves detailed design and measurement work, as well as the process of manufacturing and installation adjustment of the formwork. This increases the time and cost investment in the early stage of construction.

[0005] Extension of construction period: In traditional practice, after masonry is carried out using special-shaped formwork, it is necessary to wait for the mortar to solidify and the masonry to stabilize before subsequent plastering and finishing work can be carried out. These processes lead to an extension of the construction period.

[0006] Waste of resources: Special-shaped formwork can generally only be used in specific projects and cannot be used universally or reused, which increases material waste and environmental burden.

[0007] Technical difficulty and operational complexity: The installation and adjustment of special-shaped formwork requires construction workers to have a high level of skills and experience to ensure accuracy and quality during the construction process.

[0008] In summary, when faced with widening and re-building the lower steps of stairs, traditional methods have problems such as high cost, long construction period, insufficient resource utilization and high construction complexity, and a more effective solution is needed. Utility Model Content

[0009] The utility model aims to provide a staircase widening structure which simplifies the construction process, saves construction time and reduces construction costs.

[0010] The purpose of the utility model is achieved in this way:

[0011] A staircase widening structure, comprising a standard staircase, a prefabricated module, a screw and a nut, wherein a masonry area is formed between the standard staircase and a wall, and pre-buried first weldments are arranged at intervals at positions of the wall corresponding to the masonry area;

[0012] The side walls of the standard staircase are provided with bolt holes at intervals;

[0013] The shape of the prefabricated module matches the shape of the masonry area, the prefabricated module is separated by channels, the positions of the channels correspond to the positions of the bolt holes, the surface of the prefabricated module is provided with grooves corresponding to the positions of the channels, the grooves are connected to the channels, the diameter of the grooves is larger than the diameter of the channels, and the nuts are placed in the grooves;

[0014] The prefabricated module is provided with a pre-embedded second weldment at a position corresponding to the pre-embedded first weldment;

[0015] The prefabricated module is placed in the masonry area, the screw rod passes through the channel of the prefabricated module, the tail end of the screw rod is threadedly connected to the bolt hole of the staircase, and the head of the screw rod is threadedly connected to the nut, so that the prefabricated module and the standard staircase are locked together;

[0016] The embedded first weldment and the embedded second weldment are welded to fix the prefabricated module in the masonry area.

[0017] Simplified construction process: The combination of prefabricated modules and standard stairs avoids the complex process of customizing special-shaped templates in traditional masonry. The prefabricated modules match the design of standard stairs and are directly installed in the masonry area, greatly simplifying the construction process.

[0018] Save construction time: As prefabricated modules can be directly installed and tightly combined with standard stairs, there is no need to wait for the masonry mortar to solidify and the masonry to stabilize, and the subsequent plastering and finishing work can be carried out immediately. This method effectively shortens the construction period and improves the progress and efficiency of the project.

[0019] Reduce construction costs: Compared with the production and installation costs of customized special-shaped formwork in traditional methods, the use of prefabricated modules greatly reduces construction costs. Prefabricated modules can be prefabricated in factories, reducing on-site manpower and material waste, and saving construction costs.

[0020] Improve construction quality: The combination of prefabricated modules and standard stairs is locked by bolts and nuts to form a strong connection. This design ensures the stability and reliability of construction quality and ensures the safety and durability of the staircase structure.

[0021] Enhanced construction safety: The use of prefabricated modules reduces on-site wet work and a large amount of construction materials, reducing safety risks during construction. At the same time, the precise installation and structural stability of prefabricated modules improve construction safety.

[0022] Environmental protection and sustainability: The use of prefabricated modules reduces construction waste and material waste at the construction site, which is in line with the concept of sustainable construction. This method is conducive to improving the construction environment and reducing the negative impact on the environment.

[0023] The purpose of the utility model can also be solved by the following technical measures:

[0024] Furthermore, the prefabricated module includes rock wool and a cement surface layer, and the cement surface layer is arranged on the outer wall of the rock wool.

[0025] Excellent thermal and sound insulation performance: As part of the prefabricated module, rock wool has excellent thermal and sound insulation performance. Rock wool can effectively reduce heat transfer and sound transmission, and improve the comfort and environmental quality of the staircase structure.

[0026] Enhanced fire resistance: Rockwool material has good fire resistance and can effectively improve the fire resistance of staircase structure. In the event of a fire, rockwool can slow down the spread of fire and buy precious time for evacuation and fire extinguishing.

[0027] Improved durability and stability: As the outer surface of the prefabricated module, the cement surface layer has good durability and stability. Cement can effectively resist daily wear and tear and the influence of external environmental factors, extending the service life of the staircase structure.

[0028] Simplified construction process: The integrated design of rock wool and cement surface layer of prefabricated modules enables the thermal insulation, sound insulation and fire resistance requirements to be achieved during the installation process. This simplifies the construction process and improves construction efficiency.

[0029] Environmentally friendly and sustainable development: Using rock wool as part of prefabricated modules is in line with the concept of green building. Rock wool is renewable and recyclable, which reduces the consumption of natural resources during the construction process and is beneficial to environmental protection.

[0030] Improve the overall safety of the building: The combination of rock wool and cement surface not only enhances the fire resistance of the staircase structure, but also improves the overall safety. This design can effectively reduce the damage caused by fire and other disasters to the building and protect the safety of people and property.

[0031] Furthermore, after the prefabricated module is connected to the standard staircase, the surfaces of the prefabricated module and the standard staircase are simultaneously plastered and finished.

[0032] Save construction time: After the prefabricated modules and standard stairs are connected, plastering and finishing can be carried out immediately. This synchronous construction method greatly shortens the construction period and speeds up the project progress.

[0033] Improve construction efficiency: Simultaneous plastering and finishing avoids the idle time caused by waiting for mortar to solidify or masonry to stabilize in traditional construction. Construction workers can work continuously, improving construction efficiency and work surface utilization.

[0034] Simplified construction process: In the traditional method, after the construction is completed, the formwork needs to be removed and the masonry needs to be stabilized before plastering and finishing can be carried out, which requires multiple processes. In the new design, the subsequent decoration work can be carried out directly after the prefabricated modules and standard stairs are connected, which greatly simplifies the construction process.

[0035] Improve construction quality: Simultaneous plastering and finishing helps maintain the consistency and quality of the decorative layer. This method can reduce the joints and mismatch problems that may occur due to segmented construction, and improve the decoration effect and overall aesthetics.

[0036] Reduce construction costs: Reduce construction time and the complexity of the construction process, further reducing construction costs. At the same time, synchronous construction also reduces the manpower and equipment costs at the construction site, with significant economic benefits.

[0037] Enhanced construction safety: Continuous operation reduces the movement and modification of the construction site, reducing the risk of accidents. At the same time, workers work in the same position, which helps to improve the stability and safety of construction operations.

[0038] The beneficial effects of the utility model are as follows:
