Description

A cantilever structure for safe decoration construction

Technical Field

The invention relates to the technical field of cantilever structures, and more particularly to a cantilever structure for safe decoration construction.

Background Art

The cantilever structure is a common structural form in construction projects. It refers to a structure in which one end is supported on a vertical supporting member and the other end extends outward to extend the supporting member. This structural form is widely used in buildings, such as eaves, balconies, stadium stand ceilings, station platform ceilings, and theater platforms. The cantilever structure plays an important role in creating architectural expression and is often used to create open spaces and extend building space.

In architectural design, the scale and application methods of cantilever structures have made breakthroughs with the continuous updating of technology, gradually forming the innovation of modern architecture. The emergence of cantilever structures has also had a huge impact on the artistic modeling of modern architecture, and has endowed modern architecture with strong artistic expression. The use of cantilever structures has gradually become a major means of modern architectural modeling.

The existing cantilever structure has weak anti-overturning ability, and its overall stability is easily affected by external factors. Under the influence of natural forces such as strong winds and earthquakes, the cantilever structure is prone to overturning or becoming unstable, which not only threatens the safety of the building structure, but may also pose a threat to people's lives and property.

Summary of the invention

In order to overcome the above-mentioned deficiencies in the prior art, the present invention provides a cantilever structure for safe decoration construction, which improves the anti-overturning ability of the overall structure and strengthens its stability under the interference of external factors such as strong winds and earthquakes.

In order to solve the above technical problems, the technical solution adopted by the present invention is:

A cantilever structure for safe decoration construction comprises a bottom formwork, a fastener and a concrete beam, wherein the fasteners are arranged in parallel in multiple groups in the bottom formwork, two slots are symmetrically arranged in the fasteners, lower chord steel bars are arranged in the two slots, upper chord steel bars are arranged above the fasteners, the upper chord steel bars are connected to the lower chord steel bars on both sides by web bars, the concrete beam is arranged on the outside of the bottom formwork, the side of the concrete beam close to the bottom formwork is connected to the bottom formwork, the top of the concrete beam away from the bottom formwork is connected to a vertical beam, the top of the vertical beam is connected to a horizontally arranged cantilever beam, and the side of the cantilever beam away from the vertical beam is connected to the bottom formwork by a vertical pole.

The bottom of the upper chord steel bar is connected with a support steel bar, and the bottom of the support steel bar is fixedly connected to the bottom template.

A reinforcing steel bar is arranged on the top of the upper chord steel bar, and two ends of the reinforcing steel bar are respectively connected to the vertical beam and the vertical pole.

A groove-shaped support piece is arranged at the bottom of the bottom template, and the groove-shaped support piece is fixedly connected with the bottom template and fasteners through self-tapping screws.

A docking notch is arranged on one side of the groove-shaped support member.

A connecting support is arranged on one side surface of the concrete beam close to the bottom formwork, an inclined support is connected to the connecting support, and one end of the inclined support away from the connecting support is connected to the bottom formwork.

The connecting support is arranged on the concrete beam through fixing nails, the concrete beam is connected to the bottom formwork through a first iron nail, and the concrete beam is connected to the vertical beam through a second iron nail.

The cantilever beam is connected to the vertical beam by a first oblique tie bar, and the cantilever beam is connected to the vertical pole by a second oblique tie bar.

Compared with the prior art, the present invention has the following beneficial effects:

Through the careful arrangement of the upper chord steel bars, lower chord steel bars, web bars and innovative reinforcement steel structure system, the overall rigidity and toughness of the building structure have been significantly improved. This innovative design not only optimizes the stress mode of the traditional reinforced concrete structure, but also enhances its anti-overturning ability in multiple dimensions.

The upper and lower chord steel bars serve as the main skeleton of the structure, bearing and transmitting the loads from above and below respectively. The scientific and reasonable spacing and diameter selection between them ensure the stability of the structure in the vertical direction. The web bars, as the key link between the upper and lower chord steel bars, effectively disperse and resist lateral forces, such as wind pressure generated by strong winds, with their unique oblique arrangement, significantly improving the lateral stability of the structure.

The present invention also introduces a reinforced steel bar structure. These reinforcing bars are cleverly inserted between the main load-bearing components to form a multi-layered protection network, which further enhances the bearing capacity and deformation capacity of the structure under extreme conditions. When natural disasters such as earthquakes occur, these reinforcement measures can quickly respond and absorb seismic wave energy, reduce the amplitude of structural vibration, and thus greatly reduce the risk of structural damage;

The structure of the present invention not only greatly improves the overall safety and stability of the building structure, allowing it to remain stable in the face of harsh external environments such as strong winds and earthquakes, but also demonstrates excellent effectiveness in protecting the safety of life and property. Through the application of this innovative technology, we provide solid technical support for building a safer and more reliable modern building environment.
