Exposed square wooden column foot prestress reinforcing device applicable to high-rise wood structure

Abstract

The invention provides an exposed square wooden column foot prestress reinforcing device applicable to a high-rise wood structure. The exposed square wooden column foot prestress reinforcing device applicable to the high-rise wood structure is composed of an existing square wooden column (1), an anchorage device (2), a prestress rib (3), a flange plate (4), wrapping angle steel (5), an end plate (6), an anchor nail (7), a web (8), a web reserved hole (9), an end plate reserved hole (10) and a wrapping angle steel reserved hole (11). The exposed square wooden column foot prestress reinforcing device applicable to the high-rise wood structure is characterized in that the flange plate (4), the end plate (6), the web (8), the anchorage device (2) and the prestress rib (3) form a component part with a self-resetting function; the wrapping angle steel (5) and the web (8) wrap the square wooden column and are connected in the mode that rivets penetrate through the web reserved hole (9) and the wrapping angle steel reserved hole (11); and the anchor nail (7) is welded to the bottom face of the end plate (6) on the lower side and poured on the basis of an existing building through concrete. The exposed square wooden column foot prestress reinforcing device applicable to the high-rise wood structure can effectively conduct anti-seismic reinforcement on the square wooden column and achieve the self-resetting function of the square wooden column in the high-rise wood structure under strong earthquakes.

Description

technical field [0001] The invention relates to an exposed square wooden column foot prestressing reinforcement device suitable for high-rise wooden structures, which is applied to building structures and belongs to the field of civil engineering. Background technique [0002] In recent years, based on the continuous development and progress of engineered wood products, many high-rise residential and public wooden structures have been built. With the improvement of standards and the aging of materials, the seismic performance of some early existing high-rise wooden structures no longer meets the requirements. [0003] Under earthquake action, wooden structures tend to undergo large lateral displacements and have large residual displacements. In order to improve the anti-seismic performance of the existing high-rise wooden structure, the present invention proposes a prestressed reinforcement device for the foot of the column for the square wooden column in the high-rise wood...
