For the reinforcement of three-dimensional truss, the additional tension chord reinforcement can be adopted. The upper and lower chords of three-dimensional truss are generally continuous rods with less variation of pipe diameter and wall thickness, which can withstand larger axial force, and it is convenient to install nodal plates on the fittings with clamps, which is more suitable for adding tension chords to form a three-dimensional truss structure.
This coal shed closed reconstruction project researches the overall jacking technology in the construction of the arched space frame . There are structures that are fully utilized and lifted in stages , so that the arched space frame can be lifted and assembled at the same time , effectively improving the efficiency and quality of the arched space frame construction.
before the construction of the super-large roof steel space frame inner bridle bridge, construction planning should be done, the necessary depth of in-depth design should be carried out, and the quality control in the process should be strengthened to ensure the installation quality of the super-large roof steel space frame inner bridle bridge, and ensure that the construction can be completed at one time .
In view of the characteristics of large engineering quantity and high quality requirements of the horse road bridge frame of this project, the management team has formulated a process inspection system and a weekly meeting system to detect, analyze and correct problems in a timely manner, and continuously improve the special construction plan.
The reinforcement and renovation of the structure must be based on the actual project to carry out a multi-program comparison, under the premise of ensuring structural safety, with the principle of minimal interference with the original structural force system.
