Abstract
The utility model discloses a building frame with a vertical truss structure, which consists of a horizontal beam, a horizontal plate and a plurality of posts for supporting the beam and the plate; oblique rods are arranged between the posts; and the oblique rods between the posts and the plurality of posts jointly form a transverse-longitudinal truss structure. A vertical component originally bears a bending moment and a shearing force, but now bears pulling and pressing forces; horizontal wind power and a seismic force are changed from the original consolidated anti-bending force bearing into the pulling and pressing bearing of the oblique rods, thereby realizing the purposes of clear structural force bearing, convenient assembly and construction, and easy replacement of structural components.
Description
Technical field:
The utility model relates to a kind of building frame of vertical trussed construction.
Background technology:
According to being divided into wooden house with material different buildings structure, masonry residential, reinforced concrete structure and steel house; Steel concrete is many, framework system of high building can be divided into four classes again: frame construction, shear wall structure, Frame _ Shear Wall Structure and tubular construction.General now high level and little high residential building adopt the reinforced concrete structure form mostly.
Frame construction is the vertical, horizontal framework that utilizes post, beam to form, the structure of bearing vertical load and horizontal loading.The advantage of frame construction is the architectural plane flexible arrangement, can form bigger architectural space, and elevation of building is handled also more convenient.Its major defect is that lateral rigidity is less, when the number of plies is too much, can produce excessive sidesway, causes that easily unstructuredness member (as partition wall, decoration etc.) destroys, and influences instructions for use.Shear wall structure is a structure of utilizing the longitudinal and transverse body of wall of building to bear vertical load and horizontal loading.But longitudinal and transverse body of wall also double as for safeguarding wall or separating room wall.The advantage of shear wall structure is that lateral rigidity is big, and sidesway is little under horizontal loads.Its shortcoming is that the shear wall spacing is little, and architectural plane is arranged dumb, is not suitable for requiring the public building of large space, and dead load is also bigger in addition.
In conjunction with Fig. 1, Frame _ Shear Wall Structure is the structure that suitable shear wall 2 is set in frame construction, and it is flexible that it has the frame construction layout, and the advantage than large space is arranged, and has the big advantage of lateral rigidity again.In the Frame _ Shear Wall Structure, shear wall mainly bears horizontal loading, and vertical load is mainly born by the post 1 of framework.The beam 3 and the plate 4 of level are set on post 1 and the shear wall 2, and Frame _ Shear Wall Structure generally is used for 10～20 layers building.
Tubular construction can be divided into framework-core barrel structure, framed-tube structure, tube in tube structure, many barrel structures etc. again.
Framework-core barrel structure is made up of inner core and outside framework, and this structure stress is applicable to 10～30 layers house very near Frame _ Shear Wall Structure.
Framed-tube structure and tube in tube structure have two kinds of inner core and urceolus, and inner core generally is made up of escalator or staircase, and urceolus is generally the solid matter post and window skirt beam is formed, and can be considered the cylindrical shell in the hole of windowing.Inner core and urceolus connect into an integral body with superstructure, resist vertical load and horizontal loading jointly.The rigidity of this structural system and bearing capacity are all very big, are applicable to 30～50 layers house.
Many barrel structures then are that a plurality of tubes are combined, and make structure have the ability of bigger anti-horizontal loading.
In sum, which kind of structure no matter, vertical structure all is the combination of post and shear wall.
In the high-story house, owing to be the effect that is subjected to horizontal wind-force and seismic forces mainly, the control lateral displacement is the principal contradiction of structure design, and vertical structure post and shear wall are the member that bears moment of flexure, relies on the fixed bending resistance opposing horizontal force of node of post or shear wall.Whether the connection of frame construction beam column node directly influences structural safety, economy and construction convenient.During design, beam column adopts the concrete (strength grade of concrete of post is than deck-molding) of different brackets usually, and will notice at this moment that the position of joints strength grade of concrete is compared with post can not much lower (should not surpass 5Mpa) usually, otherwise node area should be done special disposal.In the bean column node district horizontal stirrup should be set, horizontal stirrup is answered the structural specifications of compliant.During non-seismic design, stirrup spacing should not be greater than 250mm; During seismic design, the stirrup design should meet the requirement of styletable stirrup encrypted area.Shear wall structure is like this equally, and construction is very complicated, and shear wall structure exists from great shortcoming simultaneously.Except that the vertical load that floor transmits, shear wall bears the seismic load or the wind load of horizontal force.Shear wall structure can be regarded the top freedom as, and the lower end is consolidated in the thin-walled column on basis, and its rigidity in wall body plane is very big, and outside its wall body plane, rigidity is but very little.
So, vertical structure, no matter be post or shear wall, the form of structure of this complexity to prefabricated assembling construction brought huge difficulty (also there is the building materials consumption in shear wall structure, from great, seismic forces is increased, make the shortcoming of superstructure and basic engineering difficulty), the node processing of prefabricated assembling is the emphasis and the difficult point of whole technology normally.
Owing to be to rely on consolidated node that moment of flexure, horizontal force resistance are provided, the structure stress calculation of complex adopts approximate calculation usually simultaneously.Also owing to being consolidation structure, so even prefabricated assembling is constructed, building structure also is the building that is not easy to replace structural element, so building structure is generally according to the building consideration that is not easy to replace structural element.
Summary of the invention:
For overcoming the defective of prior art, the purpose of this utility model is to provide a kind of building frame of vertical trussed construction, vertical member became and bore pulling force and pressure by bearing moment of flexure and shearing originally, horizontal wind-force and seismic forces are born by original fixed resistance to bending and become the brace tension and compression and bear, thereby implementation structure is stressed distinct, the assembling construction is convenient, and structural element is replaced purposes such as easy.
The utility model technical solution problem adopts following technical scheme:
The building frame of vertical trussed construction, described building frame is by the beam of level, plate and described beam, plate are formed many posts that support constitute, and be provided with brace between described post and post, the brace between described post and the post and many posts constitute trussed construction in length and breadth.
Compared with the prior art, the beneficial effects of the utility model are embodied in:
1, node becomes hingedly by fixed, is more conducive to prefabricated assembling construction, for the housing industrialization development facilitates.
2, node fixed become hinged, the inner complicated stress state of post and shear wall is converted into simple tension and compression stress state in the truss member, make us can understand the distribution and the transmission of internal force intuitively, be convenient to the variation and the combination of structure, make structure stress distincter, be convenient to more calculate, check.
3, node is fixed becomes hingedly, and structural element is convenient to dismounting, is replaced, and makes things convenient between the conversion cut section and the replacement of damaged component.
4, the difference of the partition of primary structure member and non-stress is cheer and bright.
