Problems solved by technology

[0005] In view of the problem that the existing prefabricated monolithic buildings are prone to wall damage due to earthquake action, the present invention provides a prefabricated monolithic energy-dissipating frame wall panel system and construction method. The energy-dissipating wall panel has a horizontal vibration space during an earthquake. And use the damping force provided by the viscous damper to dissipate energy, reduce the vibration response of the structure, and avoid premature damage of the structure when the earthquake acts, thus having better earthquake resistance and disaster reduction capabilities

Embodiment 1

[0047] see figure 1 with figure 2 As shown, the assembled integrated energy-dissipating frame wall panel system provided by the present invention includes prefabricated columns 100 , prefabricated beams 200 , energy-dissipating wall panels 300 , viscous dampers 400 and cover plates 500 .

[0048] Among them, such as figure 2As shown, the prefabricated columns 100 are vertically arranged at intervals in parallel, the prefabricated beams 200 span the prefabricated columns 100 , and the joints of the prefabricated beams 200 and the prefabricated columns 100 are integrally formed by cast-in-place concrete. Preferably, the top of the longitudinal reinforcement of the prefabricated column 100 is connected with a sleeve 110, and the gap between the sleeve 110 and the longitudinal reinforcement of the prefabricated column 100 is filled with grouting liquid. Grouting of the sleeve 110 is a common technique and will not be repeated here. Wherein, the prefabricated beam 200 and the p...

Embodiment 2

[0058] The present invention also provides a construction method for assembling the integral energy-dissipating frame wall panel system in Embodiment 1, which includes the following steps:

[0059] S1. Lift the prefabricated column 100 to the designed position, then fix the sleeve 110 on the longitudinal reinforcement of the prefabricated column 100 , and inject grout into the sleeve 110 . The prefabricated columns 100 are arranged vertically, and the sleeves 110 are arranged on the longitudinal steel bars, so as to facilitate docking with the longitudinal steel bars of the upper precast column 100 . Using the sleeve 110 to connect the longitudinal steel bars of the prefabricated components is a prior art, which will not be repeated here.

[0060] S2. Lift the prefabricated beam 200 to the top of the prefabricated columns 100 on both sides, and adjust the elevation of the prefabricated beam 200 to the design position.

[0061] S3. Set up the formwork and pour the joints betwe...

Abstract

The invention belongs to the field of civil engineering structure, and particularly relates to an assembled integral type energy-consuming framework wallboard system and a construction method. The energy-consuming framework wallboard system comprises precast columns, precast beams, energy-consuming wallboards, viscous dampers and cover plates, wherein the precast columns and the precast beams forman assembled integral type framework, the energy-consuming wallboards are fixed on the precast beams, and adjacent energy-consuming wallboards are spliced together by the viscous dampers and the cover plates. In earthquake, the energy-consuming wallboards have a horizontal shaking space, energy dissipation is realized by utilizing damping force provided by the viscous dampers, so as to reduce vibration response of the structure, and avoid too early damage of the structure in the action of the earthquake, and therefore, a better earthquake prevention and disaster reduction capacity is achieved. In addition, the construction method is reasonable in procedure, convenient to operate, and convenient to popularize, and an assembled integral type energy-consuming framework wallboard system withfirm structure and excellent earthquake prevention and disaster reduction effect can be formed.

Description

technical field [0001] The invention belongs to the field of civil engineering structures, and in particular relates to an assembled integral energy-dissipating frame wallboard system and a construction method. Background technique [0002] With the advancement of construction industrialization, the assembled monolithic concrete structure has become a hot spot in the national construction market, and its scale and prefabrication rate are constantly increasing. With the enhancement of environmental protection awareness, some provinces and cities have launched green building plans, and more and more load-bearing components will inevitably be manufactured using prefabricated assembly processes. [0003] Assembled integral concrete structure refers to a concrete structure in which prefabricated concrete components are rigidly connected by post-casting on site, such as a rigid frame structure. The commonly used method is to leave negative moment reinforcement on the prefabricate...
