A connection method between prefabricated concrete wall panel and main structure

Abstract

The invention discloses a novel connection mode between a prefabricated concrete wall and a main structure and belongs to the technical field of prefabricated concrete component in housing industrialization. The novel connection mode comprises: connecting the upper part of the prefabricated concrete wall with a concrete beam, a beam hook and a wall hook in a flexible connection; filling in gaps on the side edges of the prefabricated concrete wall with rubber bricks to reduce the acting force exerted by a pillar on the prefabricated concrete wall at an earthquake; limiting the bottom part of the prefabricated concrete wall by a bottom-part blocking plate to prevent the prefabricated concrete wall from wobbling transversely. Suspension connecting mode is primary in the novel connection mode, gaps between the side edges of the prefabricated concrete wall and pillars are filled with the rubber bricks as a base-isolated device and the limit connection is arranged on the bottom part of the prefabricated concreted wall. According to this arrangement, the energy-dissipating capacity of the structure is improved, transverse wobbling of the prefabricated concrete wall is prevented, and the rigidity is reduced compared with that of a wet connection so that the prefabricated concrete wall of a building designed by standards of frame structure is effectively protected at an earthquake.

Description

technical field [0001] The invention belongs to the technical field of prefabricated concrete components in housing industrialization, and in particular relates to a connection method between a prefabricated concrete wall panel and a main structure. technical background [0002] Compared with masonry walls, prefabricated concrete wall panels have better integrity and strength, and do not need to be bonded with mortar like masonry, so that no serious damage will occur when this kind of filling wall is damaged. There are mainly two types of connection between the precast concrete wall panel and the main body: the external hanging type and the side connection type. The external hanging type is mainly connected to the beam by the upper part of the wall panel through a dry connection, and the side and bottom edges are only used for limit connections. The effect of the wall panels is hardly considered in the design, and the whole wall panels may fall off and collapse during an ear...

There are mainly two types of connection between the precast concrete wall panel and the main body: the external hanging type and the side connection type. The external hanging type is mainly connected to the beam by the upper part of the wall panel through a dry connection, and the side and bottom edges are only used for limit connections. In the design, the function of the wall panels is hardly considered, and it is likely to cause the overall shedding and collapse of the wall panels during an earthquake.

The side-connected type mainly relies on the side of the wall panel to be connected to the column through wet connection, and the lower side only has a limited connection, so it greatly increases the rigidity of the structure like a masonry wall, and it is easy to cause severe cracking of the wall panel during an earthquake and destroy
