AI Technical Summary

Technical Problem

In the construction of large-span steel concrete beam and column structures, the geometric shape of the node area is complex and the stress is concentrated, resulting in the outer formwork being easily deformed, displaced and even exploded during concrete pouring, affecting the forming quality and structural performance. Existing reinforcement devices are difficult to adapt to changes in different node shapes, especially the reinforcement effect of large-span structures with gradient cross-sections is poor, and the applicability and rapid construction requirements are difficult to meet.

Method used

A large-span steel concrete beam and column structure construction node reinforcement device is designed, including support platform, main hydraulic push rod, U-shaped plate, reinforced structure, etc. The reinforcement structure is driven by a sub-hydraulic push rod to move the adjustment arm and the fixed plate, realizing bidirectional reinforcement of the external template and adapting to node reinforcement of different shapes.

Benefits of technology

This device can quickly reinforcing the outer formwork of the concrete construction node of gradient section steel, improve the adaptability to the shape of complex nodes, and ensure the satisfaction of concrete forming quality and structural performance.

Abstract

The invention relates to the technical field of steel reinforced concrete construction equipment, in particular to a large-span steel reinforced concrete beam column structure construction joint reinforcing device which comprises a supporting platform placed on the construction ground, and supporting columns are symmetrically installed on the top of the supporting platform and close to the edge of the supporting platform. A main hydraulic push rod is installed in the middle of the upper end face of the supporting platform, a U-shaped plate is fixedly connected to the end face of a piston rod at the top of the main hydraulic push rod, positioning lugs are welded to the outer walls of the two sides of the U-shaped plate and inserted into the outer walls of the supporting columns, and a reinforcing structure for externally fixing the steel reinforced concrete beam column construction joint is installed at the top of the U-shaped plate. The reinforcing structure comprises an outer shell fixedly connected with the U-shaped plate, inclined holes are symmetrically formed in the bottom of the outer shell, a secondary hydraulic push rod is installed at the bottom of the outer shell, and a top piston rod of the secondary hydraulic push rod penetrates through the outer shell. The method has the reinforcing requirement suitable for gradient interface construction nodes, and the applicability is wider.
