Description

BACKGROUND

In the whole life cycle, it saves resources, protects the environment, reduces pollution, provides healthy, suitable and efficient use space for people, and maximizes the realization of high-quality buildings of harmonious coexistence between man and nature.

[0003] The node in the steel structure refers to the part connecting different components, and is one of the most important components of the structure. The node in the steel structure bears the function of connection and load transmission, and is also the weak point of the structure, which needs to be carefully designed and strengthened. Among them, the welded node is the most common one, which forms a firm connection by melting the surface of the component at high temperature and cooling down. When designing the node, the appropriate node form needs to be selected according to the actual situation, and the strength and stiffness of the node need to be ensured to meet the design requirements. In addition, the node also needs to consider the problems of corrosion prevention and fire prevention to ensure the long-term use of the component. The design and strengthening of the node have a crucial influence on the safety, reliability, economy and other aspects of the whole structure.

[0004] According to the patent CN 106988418 B, a kind of assembly method of fabricated steel structure beam column node is provided, the assembly method includes the following steps: a), prefabricated steel pipe column and steel pipe beam, two mutually perpendicular steel pipe cantilever beams are welded at the upper side end of steel pipe column;B), steel pipe column fixation;C), steel pipe beam hoisting, the steel pipe beam is hoisted to the fixed steel pipe column between adjacent, the steel pipe beam end and the steel pipe cantilever beam extension end abut;D), steel pipe beam fixation, the steel pipe beam and steel pipe cantilever beam are fixed by high-strength bolt.The assembly method of fabricated steel structure beam column node provided by the present application is simple in assembly operation, realizes the rapid assembly process between steel pipe column and steel pipe beam, and the assembly between steel pipe column and steel pipe beam is more stable.

Since the steel structure is high, the staff needs to use climbing tools to clean the corroded corrosion-resistant paint on the surface of the node. After the corrosion-resistant paint is cleaned, new corrosion-resistant paint is sprayed again, the staff needs to descend to the ground to carry the new corrosion-resistant paint and climb again to replace the paint, which is troublesome and has safety hazards.

A construction technique for strengthening local nodes of steel structures based on green and energy-saving buildings, characterized in that, To employ the steel structure local node reinforcement system based on green and energy-saving buildings as described in any one of claims 1 to 4, the construction process for this steel structure local node reinforcement specifically includes the following steps: S1. Drive the synchronous drive component to transmit power, so that the cleaning component drives the moving parts to move while cleaning. S2. Transmission is achieved through a synchronous drive component, and the moving parts drive the spraying component to spray material while the moving parts move. S3. When the equipment needs to be replenished with liquid after running for a period of time, drive the material changing component to change the material.

6. The construction process for strengthening local nodes of steel structures based on green and energy-saving buildings according to claim 5, characterized in that, In step 1, the synchronous drive component rotates forward for two seconds, causing the cleaning component to clean the node surface while simultaneously moving the moving component to the left. In step 2, the synchronous drive component rotates forward for three seconds, causing the moving component to move while the synchronous drive component drives the spraying component to spray material. In step 3, when the equipment sprays material back and forth three times, the material needs to be replaced, and the material replacement component is driven to descend to replace the material.
