Abstract

The invention discloses a fire resistant beam column joint with a groove type end plate. The fire resistant beam column joint comprises a steel column, a steel beam and the end plate; the steel beam is in butt welding with the end plate; the end plate is connected with the steel column through bolts; the end plate is the groove type end plate; the bolts are high-strength bolts; the steel beam is I-shaped or H-shaped; the groove type end plate is connected with the steel column through a groove type extension end plate, a groove type flat end plate or a groove type web end plate; and the groove type end plate is connected with the steel column through an outward reversing flange. The fire resistant beam column joint has the advantages of ensuring the full exertion of suspended connection line effect of the steel beam, increasing anti-collapse capacity of the structure, supplying certain rotation capacity for the steel beam, avoiding the damage on the high-strength bolts and being suitable for industrial and civil steel frame structures with high requirements for the fire resistance performance and anti-collapse capacity of the structure.

Description

The grooved end plate resists fiery type bean column node
Technical field
The present invention relates to a kind of steel framed structure bean column node, particularly a kind of grooved end plate resists fiery type bean column node.
Technical background
Along with Development of High-rise Buildings is more and more faster, highly constantly raise, the high-rise fire accident happens occasionally, and the structure fire of highrise building can cause the damage of structure or collapse.Therefore need to improve the ability of structure fire-resistant; For the target that guarantees structure fire-resistant design, make structure in the back certain hour fire breaks out, still have certain supporting capacity and deformability; Prevent to collapse; To guarantee safety evacuation in the building, the safe transfer of property reaches the attack time that the fire fighter has abundance; Standard all is through guaranteeing that independent member meets the demands in the performance under the fire, guaranteeing integrally-built safety like quantity that increases bolt and the measures such as intensity that improve bolt both at home and abroad at present.The defective of this method is; The behavior of fire lower member in overall structure has a great difference with the behavior of independent member, and the fire resistance of member can not be represented integrally-built fire resistance fully separately, exists the problem of the anti-ability of collapsing of structure; The calamity " Invest, Then Investigate " of overall structure experimental study and actual fire is found; Girder steel can produce outstanding line effect under the fire condition, and can bear very high temperature and produce large deformation and do not rupture, and will guarantee giving full play to of the outstanding line effect of girder steel; Only increase bolt quantity and improve the bolt strength DeGrain; And need to improve node region turning power at high temperature, thus guarantee that the outstanding line effect of girder steel is not fully exerted, improve the anti-ability of collapsing of structure.
Summary of the invention
The object of the invention is exactly to increase bolt quantity in order to solve taking merely that prior art exists, improve the bolt strength measure and guarantee integrally-built safety; Can not improve at high temperature turning power of node region well, make the outstanding line effect of girder steel be not fully exerted the problem of the anti-ability of collapsing of structure; Provide a kind of grooved end plate to resist fiery type bean column node; Giving full play to of the outstanding line effect of assurance girder steel improved the anti-ability of collapsing of structure.To girder steel certain turning power is provided during fire, has avoided the destruction of high-strength bolt, improve the anti-ability of collapsing of structure, be applicable to structure fire resistance performance and anti-collapse Capability Requirement high industry and civilian steel framed structure.
For realizing above-mentioned purpose, the present invention adopts following technical scheme:
A kind of grooved end plate resists fiery type bean column node, comprises steel column, girder steel, end plate, and said girder steel adopts with end plate and docks welding, and said end plate is connected through bolt with steel column, and said end plate is the grooved end plate, and said bolt is a high-strength bolt.
Said girder steel is i shaped steel or H shaped steel.
Said grooved end plate is connected with steel column through grooved extended end plate, grooved flush end plate or grooved web end plate.
Said grooved end plate links to each other with steel column through the edge of a wing of turning up.
Operating principle of the present invention: the present invention includes steel column, girder steel, end plate, said girder steel adopts with end plate and docks welding, and said end plate is connected through bolt with steel column, and said end plate is the grooved end plate, and said bolt is a high-strength bolt.Said girder steel is i shaped steel or H shaped steel.Said grooved end plate is connected with steel column through grooved extended end plate, grooved flush end plate or grooved web end plate.Said grooved end plate links to each other with steel column through the edge of a wing of turning up.The web size of grooved end plate adopt greater than, equal or less than girder steel up and down flange width can both satisfy instructions for use.
Beneficial effect of the present invention:
1, grooved end plate web produces bigger distortion when running into fire, to girder steel certain turning power is provided, and avoids the destruction of high-strength bolt;
2. improve the survival ability of node, guarantee the performance of the outstanding line effect of girder steel, improve the anti-ability of collapsing of structure;
3. simple structure, reliability height are cheap, are convenient to construction, and fire resistance is good;
4. be applicable to structure fire resistance performance and anti-collapse Capability Requirement high industry and civilian steel framed structure.
Description of drawings
Fig. 1 is a front view of the present invention;
Fig. 2 is a left view of the present invention;
Fig. 3 is a vertical view of the present invention;
Among the figure, 1. steel column; 2. girder steel; 3. end plate; 4. bolt; 5. grooved end plate web.
The specific embodiment
Below in conjunction with accompanying drawing and embodiment the present invention is further specified.
A kind of grooved end plate resists fiery type bean column node, in conjunction with Fig. 1 to Fig. 3, comprises steel column 1, girder steel 2, end plate 3 and bolt 4; Said girder steel 2 adopts with end plate 3 and docks welding; Said end plate 3 is connected through bolt 4 with steel column 1, and said end plate is the grooved end plate, and said bolt is a high-strength bolt; Said girder steel 2 is i shaped steel or H shaped steel, and said grooved end plate 3 is connected with steel column 1 through grooved extended end plate, grooved flush end plate or grooved web end plate.Said grooved end plate web 5 sizes adopt greater than, equal or less than girder steel about in the of 2 flange width can both meet the demands, said grooved end plate 3 links to each other with steel column 1 through the edge of a wing of turning up.
Though the above-mentioned accompanying drawing that combines is described the specific embodiment of invention; But be not restriction to protection domain of the present invention; One of ordinary skill in the art should be understood that; On the basis of technical scheme of the present invention, those skilled in the art need not pay various modifications that creative work can make or distortion still in protection scope of the present invention.
