Construction method for high-rise large-span stiff damping structure

Abstract

The invention discloses a construction method for a high-rise large-span stiff damping structure. The method comprises the following steps of performing secondary deepening; preparing for construction; mounting beam column templates on a damping part; mounting beam bottom screw punching fixing plates; placing beam bottom reinforcements; placing stiff steel beams in place; mounting stiff steel beam screws; fixedly welding the steel beams; binding frame beam reinforcements; performing limiting by using the 3mm-thick fixing steel plates at the top ends of the screws; pouring stiff concrete; correcting and rechecking the damping structure screws; mounting T-shaped steel joints on the two sides; mounting middle pin seat joints; mounting a bottom transverse H-shaped steel support; fixedly mounting an H-shaped bracket; filling a strong-strength grouting material at the bottom of a base; mounting a damper and combined pin seats on the two sides of the damper; cutting temporary angle steel of side limiting plates, and performing field weld joint detection. The method has the beneficial effects that compared with a conventional structure, the stiff damping structure has the advantages that the cost of an energy dissipation element is increased, but the using amounts of reinforcements, shape steel and concrete are reduced.

Description

technical field

[0001] The invention relates to a construction method for a high-rise large-span damping structure, which belongs to the technical field of building construction. Background technique

[0002] With the continuous development of urban construction, high-rise buildings in highly fortified areas have sprung up like mushrooms, and there are more and more functional requirements for high-rise buildings and large bays. Many buildings in high-earthquake areas in China have been retrofitted with damping structures for seismic reinforcement, and good results have been achieved, but the overall cost of buildings and many problems in the renovation have greatly increased. Moreover, the reinforced buildings are far from being able to meet the high-rise and long-span functions of modern buildings and the requirements of environmental protection, economy and energy saving due to their own limitations.

[0003] Therefore, in the new high-rise long-span project, technol...

Examples

Embodiment Construction

[0055] According to the principle of three holes and one line, the screw is accurately pre-embedded for damping and installing the screw at three levels of the rigid structure frame beam bottom, the upper and lower flange plates of the stiff steel beam, and the screw is perforated and positioned; and the screw is perforated and positioned at the top of the screw. Effectively control the reserved accuracy of the screw at the bottom of the beam and the floor; after the screw is corrected in place, the stiff steel beam is welded to the frame column and the embedded parts at the end of the column; the height of the damping structure is reduced by 50mm through the second deepening design and carried out The components are disassembled and processed uniformly in the manufacturer. The damping structure installs each deepening component through the screw reserved for the rigid structure, and the pin seat nodes, brackets, dampers, and bases of the damping structure are installed in place...
