Description
Technical field
The invention belongs to timber buildings antidetonation and maintenance areas, are related to a kind of dress for beam-column joint reinforcing protection
It sets, and in particular to a kind of device for the protection of timber structure beam-column joint reinforcing.
Background technique
Component of the traditional timber buildings of China using gallows timber as the main bearing load of building.In order to protect
Each component of card gallows timber is owned by enough bearing capacities, and ancient times craftsman teachers take many measures.One of method is
Change material etc., using different materials etc., the internal force of component can also be changed correspondingly, and meet the requirements the bearing capacity of component with this.
And another kind is exactly by variation effective span, to change the internal force of component.And decorated bracket is exactly for component herein.
Decorated bracket, also referred to as " pin " or " bolster " are usually placed in the junction of beam or late volume and column.The blank of decorated bracket exists
The Northern Wei Dynasty just has already appeared, but it is early stage appearance, is only merely a beam of commitment door screen volume on column.With the evolution of structure
Development, the shape of decorated bracket are gradually rich and varied.Profile is gradually varied to curve by straight line, while having birds and flowers, gaily decorated basket etc.
Various moulding.Decorated bracket increasingly becomes indispensable decoration element in building, and the aesthetic effect played is increasing.I.e.
Just in this way, decorated bracket still plays irreplaceable mechanical function.Decorated bracket is mounted on the place that horizontal material intersects with perpendicular material, it can be with
The net span for shortening beam, to improve the bearing capacity of beam.Meanwhile decorated bracket can reduce the shearing of beam and column joint with support beam.
The variation of angle between beam column can be prevented simultaneously.
There are also many similar designs in timber structure, such as are frequently used under palace below flat Quan and remaining room Quan and replace wood
Support.Monobucket can be divided into for timber saddle according to the form of support for timber saddle, a material enables arch support, support between two materials button loop between fastening with a rope, string, etc.
Deng.The rigidity of different supports is different, also different to the binding effect of Quan, can in various degree in different situations
The net span for reducing beam, to improve the bearing capacity of beam.
In modern architecture, in order to cope with earthquake load, the safety of structure is protected often to use damper, and metal is bent
It is one of for taking damper.Metal damper occurs plastic deformation and surrenders first under geological process.Metal damper
It can be by this deformation to consume the energy that most of earthquake is transmitted.Currently, common damper has mild steel damper, lead resistance
The dampers such as Buddhist nun's device and marmem damper.Metal damper production is simple, and easy for installation, energy consumption effect is good, cost
