Abstract
A kind of assembled post post bolt connection combination structure node, belongs to technical field of structural engineering, and node includes post, suspension hook, bent plate, nut and bolt.Nut welds with bent plate hole to it, and the upper and lower side in pillar is respectively welded in suspension hook and bent plate.The assembled post post bolt connection combination structure node welding portion of the present invention is completed in factory, is carried out assembled in situ using lifting, is bolted after the completion of lifting and is poured in column interior and fill up concrete.Because pillar tie point is near inflection point, inflection point stress is smaller, and the armored concrete that concrete and the bent plate and suspension hook of column interior are formed has certain connection function, the size of suspension hook and bent plate, length can adjust, to adjust attachment force, and be connected between upper lower prop by bolt, therefore the connection between upper lower prop meets the requirement of assembling type steel structure node.The assembled post post bolt connection combination structure node can increase substantially speed of application and quality, fully adapt to the development of assembling type steel structure.
Description
Technical field
The present invention relates to a kind of assembled post post bolt connection combination structure node, belong to technical field of structural engineering.
Background technology
Assembling type steel structure system refers to the building subassembly specification making house unit or component according to unification, standard, so
After be transported to job site and assemble building in place and caused.It is characterized in that construction quality light, energy-conserving and environment-protective, speed of application be fast, work
Industry degree height etc., can solve that China's building industrialization level is low, house building labor productivity is low and conventional house product
The problems such as quality is low, adapt to the development of China's building trade.
Pillar joint connection manner is connected mode important in assembling type steel structure system, and it directly affects structure
Speed of application and assembling degree, thus pillar joint should try one's best it is more by the way of easy to operation and its bearing capacity not
There can be more obvious reduction.The pillar joint connection manner used in existing case history has the following disadvantages：
(l) influenceed by high temperature when welding；(2) base metal that weld seam is easily present near various poor welds is easily caused material
Qualitative change is crisp, thus causes to produce stress concentration in component and expand crackle；(3) because welded rigidity is big, Ge Biecun
Localized crackses easily expand to entirety；(4) after welding, ununiform shrinkage during due to cooling is residual there will be welding in component
Residue stress, partial cross section during component load-bearing can be made to enter plasticity in advance, reduce the Critical Stability stress of component when being pressurized；(5) weld
After connecing, made due to uneven breathing component produce welding residual deformation, such as make be originally plane steel plate occur deformation of unevenness；
(6) when plain bolt connecting bolt precision is low, should not be cut, processing and installation difficulty is larger when bolt precision is high；(7) high intensity
Rubbing surface processing mounting process is slightly complicated during bolt connection, and cost is slightly higher, and is easily loosened under dynamic action.
The present invention proposes a kind of assembled post post bolt connection combination structure node, can effectively solve job site upper prop
Orientation problem when being connected with lower prop；Casting concrete in post, its fire protecting performance there has also been the raising of certain amplitude；It is curved in post
Plate and suspension hook are combined with concrete, form reinforced concrete structure, can not only play a part of connecting pillar, and effectively change
The stress performance of kind pillar.It is bolted between upper prop and lower prop, meets the requirement of assembling type steel structure component splicing.Portion
Divide component to weld completion in factory, improve the assembled speed at scene.
The content of the invention
The present invention proposes assembled post post bolt connection combination structure node, and its object is to overcome prior art to lack
Fall into, meet node items mechanical property, and realize the assembling between construction module, improve the assembled speed of component, fully adapt to dress
Requirement and feature with formula steel structure system.
Technical scheme is as follows：
A kind of pillar joint connection of assembling type steel structure system, it is characterised in that：The attachment means include post
(1), suspension hook (2), bent plate (3), nut (4) and bolt (5)；
The nut (4) is welded in the inner surface of bent plate (3), bent plate (3) perforate, hole center and nut (4) hole center pair
Neat member of formation A1；
Each post lower end is respectively provided with component A1, and upper end is respectively provided with suspension hook (2)；Suspension hook (2) is welded in post (1) upper end inner surface
Two diagonal at and in cross-shaped；Four component A1 are respectively welded at four inner surfaces of post (1) lower end；
Post (1) upper end perforate, bore size is identical with bent plate (3) bore size, and after the completion of upper lower prop grafting, post (1)
Position of opening and component A1 position of opening center alignments；
The post (1) and suspension hook (2), post (1) and component A1 are integrally welded in factory, member of formation after the completion of welding
A2。
The grafting up and down for fitting through component A2 of upper lower prop is completed, and is screwed into up and down by bolt after the completion of component A2 grafting
In the reserved bolt hole of post, and tightened by nut, connection is completed to pour inside post to fill up concrete.
Beneficial effect
A kind of assembled post post bolt connection combination structure node of the present invention, partial component weld completion in factory,
Suspension hook plays a part of hanging in work progress connects weight, and bent plate plays the effect in place of guiding pillar in installation process.
It is bolted after the completion of lifting and fills up concrete by being poured in pillar.Casting concrete in post, can be in certain amplitude
Improve the fire protecting performance of pillar.The bent plate and suspension hook of column interior casting concrete and column interior combine to form armored concrete
Structure.According to the length of the loading characteristic of pillar adjustment suspension hook and bent plate to realize the anchoring of armored concrete, therefore pour mixed
The connection of some strength is realized after solidifying soil.Because pillar tie point is near inflection point, inflection point stress is smaller, and concrete
The armored concrete formed with the bent plate and suspension hook of column interior has size, the length of certain connection function, suspension hook and bent plate
It can adjust, to adjust attachment force, and be connected between upper lower prop by bolt, therefore the connection between upper lower prop meets assembled
The requirement of steel structure node.This assembled post post bolt connection combination structure node effectively increases assembling speed and quality.
