Embodiment Construction

[0023] The present invention will be further described below in conjunction with the embodiments shown in the accompanying drawings.

[0024] Such as figure 1 As shown, the present invention includes several pieces of energy-dissipating bamboo chips 5 , a first wooden connector 1 , a second wooden connector 4 , steel bolts 2 and steel nuts 3 , and diagonal bracing wooden rods 6 . The present invention is installed in the upper and lower wooden frame beams 7,8 and the left and right wooden frame columns 9,10 of the building structure. The energy-dissipating bamboo chips used in the present invention are preferably 5-20 pieces, specifically determined through structural calculation.

[0025] The energy-dissipating bamboo pieces 5 are connected to the first wooden connector 1 and the second wooden connector 4 at the upper and lower ends respectively through steel bolts 2 and steel nuts 3 . The bottom of the upper wooden frame beam 7 inside the wooden structure is provided with ...

Abstract

The invention relates to a compound wood-bamboo energy-absorbing and damping support structure, belonging to construction field. The support structure, applicable on wooden buildings, is made of wood and bamboo and comprises an energy-absorbing bamboo plate, wooden connecting pieces, and a wooden slanting support pole. The upper end and the lower end of the energy-absorbing bamboo plate are respectively connected with the wooden connecting pieces, and the wooden connecting piece at the lower end is also connected with the wooden slanting support pole. The support structure is respectively connected with upper and lower girders of a wooden frame of the building through the wooden connecting piece at the upper end and the wooden slanting support pole, and is fixed and installed in the wooden frame. The support structure is installed in the wooden frame which demands shock resistance and is simple in connection with the main body of the wooden frame, convenient to construct and reliable in force transmission and is simple to replace and maintain if being damaged in an earthquake. The support structure can be used to reduce earthquake impact on small wooden buildings to help small wooden buildings to avoid and minimize damages in earthquakes.

Description

technical field [0001] The invention belongs to the field of construction, and relates to an energy dissipation and shock absorption control device for a wooden structure of a building, which can be used to reduce the seismic response of the wooden structure of the building, thereby avoiding or reducing the earthquake damage of the wooden structure. Background technique [0002] Wood has the advantages of safety, comfort, and low thermal efficiency. It is an ideal natural building material. Wooden structures built with wood have the advantages of fast construction speed and environmental protection. A large number of wooden structure systems have been used in ancient buildings in our country. In recent years, although most urban buildings are mainly reinforced concrete structures and steel structures, wooden structures are still widely popular in township buildings and characteristic buildings. During the magnitude 8.0 earthquake in Wenchuan, Sichuan in May 2008, many wooden...
