An assembled glulam constrained buckling-resistant energy-dissipating brace

Abstract

The invention discloses an assembly type laminated wood constraint buckling-restrained brace, comprising an inner core, a peripheral constraint part and a filling steel plate; the inner core comprises a connecting steel plate, a connecting steel plate stiffening rib, a connecting end place, a connecting section stiffening plate, a buckling section, a limiting card, a transition section and a connecting section; the peripheral constraint part is an orthogonal laminated wood and is formed by combination of upper and lower laminated wood and left and right laminated wood; and the buckling section and the transition section of the inner core are arranged in the peripheral constraint part, the filling steel plate is arranged between the buckling section of the inner core and the upper and lower laminated wood of the peripheral constraint part, and a tiny gap is reserved between the buckling section of the inner core and the filling steel plate. According to the invention, the ductility and the energy dissipating capacity of a support structure of a wood frame are improved, and assembly type production can be carried out on the brace in a factory, so that field construction work load can be reduced, construction progress can be promoted, connecting quality can be ensured, and structure installation is facilitated. When being used in an earthquake region, the brace is convenient for post-earthquake repair and can reduce earthquake damage.

Description

technical field [0001] The invention belongs to the technical field of wood structure engineering, and in particular relates to a novel assembled glulam constrained anti-buckling energy-dissipating support. Background technique [0002] The wooden structure conforms to the concept of low-carbon environmental protection and green ecology. With the reduction of construction land and the increase of population, the development of medium and high-rise wooden structure buildings has become an important trend. Compared with the traditional wooden structure, the middle and high-rise wooden structure building adopts the construction method of factory prefabricated on-site assembly components, which makes the construction efficiency of the house higher and faster. And it has the advantage of saving land, and it is one of the development directions of wood structure in my country, but the domestic research is still in a blank stage.

Problems solved by technology

[0004] The purpose of the present invention is to overcome the weak lateral rigidity and large deformation when the wooden frame is used alone, while the main lateral force-resistant member in the existing wooden frame-support structure is a wooden support, and when bearing the horizontal force, it will not be compatible with the support. The steel plate at the connection is prone to buckling, the bolts are cut off, and the support will also crack, so that the support structure loses its bearing capacity and insufficient seismic performance. A new type of buckling-resistant energy-dissipating support is provided to make the wooden frame-support structure. Form a whole, give full play to its ductility and energy dissipation capacity, and help to achieve breakthroughs in height and span of wooden structures
