A prefabricated bolt-connected reinforced wood restrained buckling-resistant energy-dissipating brace

Abstract

The invention discloses an assembly type bolted connection reinforced wood constraint buckling-restrained brace, comprising an inner core, a peripheral constraint part, a steel filler strip and a filling steel plate; the peripheral constraint part is formed by upper laminated wood and lower laminated wood which are connected by bolts, bolt holes are formed in the laminated wood, the steel filter strip is arranged between the upper and lower laminated wood, and the upper and lower laminated wood are connected into a whole by gluing pressurization; 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 laminated wood of the peripheral constraint part, preformed holes are formed in the filling steel plate, a tiny gas is reserved between the buckling section of the inner core and the filling steel plate, and the filling steel plate is connected with the laminated wood of the peripheral constraint part by gluing pressurization. The brace can improve the ductility and the energy dissipating capacity of the support structure of a wood frame, 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, connection quality can be ensured, and structure installation is facilitated.

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] Wooden structures are low-carbon, environmentally friendly, and green. With the reduction of construction land and the growth of population, the development of medium and high-rise wooden structures 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.

AI Technical Summary

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
