Abstract
The utility model discloses a groove-type end plate fire-proof beam-column joint which comprises a steel column, a steel beam and an end plate, wherein the steel beam and the end plate are subjected to butt welding; the end plate and the steel column are connected through a bolt; the end plate is a groove-type end plate; the bolt is a high-strength bolt; and the steel beam is of I-shaped steel or H-shaped steel. The groove-type end plate is connected with the steel column by a groove-type overhung end plate, a groove-type flat end plate or a groove-type web plate end plate, and the groove-type end plate is connected with the steel column through an evaginable flange, so that the suspended connection effect of the steel beam is fully exerted, the collapse-resisting capability of the structure is improved, certain rotating capability is provided for the steel beam during a fire disaster, the high-tensile bolt is prevented from being damaged, and the collapse-resisting capability of the structure is improved; and the groove-type end plate fire-proof beam-column joint is applicable to the industrial and civil steel frame structures with high requirements on the fire-proof performance and the collapse-resisting capability.
Description
Technical field
The utility model relates to a kind of steel framed structure bean column node, particularly the anti-fiery type bean column node of a kind of grooved end plate.
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 after fire occurs, still have certain supporting capacity and deformability in the certain hour, prevent from collapsing, to guarantee safety evacuation in the building, the safe transfer of property, and the fire fighter has sufficient attack time, standard all is by guaranteeing that independent member meets the demands in the performance under the fire, guaranteeing integrally-built safety such as the 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, the fire resistance of member can not represent integrally-built fire resistance fully separately, exist the poor problem of structure collapse resistant capacity, the calamity " Invest, Then Investigate " of integral model test research 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 fracture not, and to 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, thereby guarantee that the outstanding line effect of girder steel is not fully exerted, and improves the collapse resistant capacity of structure.
Summary of the invention
The purpose of this utility model 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 well node region turning power at high temperature so that the outstanding line effect of girder steel is not fully exerted the problem that the structure collapse resistant capacity is poor; Provide a kind of grooved end plate anti-fiery type bean column node; Giving full play to of the outstanding line effect of assurance girder steel improved the collapse resistant capacity of structure.Provide certain turning power to girder steel during fire, avoided the destruction of high-strength bolt, improve the collapse resistant capacity of structure, be applicable to the demanding industry of structure fire resistance performance and collapse resistant capacity and civilian steel framed structure.
For achieving the above object, the utility model adopts following technical scheme:
The anti-fiery type bean column node of a kind of grooved end plate comprises steel column, girder steel, end plate, and described girder steel adopts with end plate and docks welding, and described end plate and steel column are bolted, and described end plate is the grooved end plate, and described bolt is high-strength bolt.
Described girder steel is i shaped steel or H shaped steel.
Described grooved end plate is connected with steel column by grooved extended end plate, grooved flush end plate or grooved web end plate.
Described grooved end plate links to each other with steel column by the edge of a wing of turning up.
Operating principle of the present utility model: the utility model comprises steel column, girder steel, end plate, and described girder steel adopts with end plate and docks welding, and described end plate and steel column are bolted, and described end plate is the grooved end plate, and described bolt is high-strength bolt.Described girder steel is i shaped steel or H shaped steel.Described grooved end plate is connected with steel column by grooved extended end plate, grooved flush end plate or grooved web end plate.Described grooved end plate links to each other with steel column by 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.
The beneficial effects of the utility model:
1, grooved end plate web produces larger distortion when running into fire, provides certain turning power to girder steel, 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 collapse resistant capacity of structure;
3. simple structure, reliability are high, cheap, constructability, and fire resistance is good;
4. be applicable to the demanding industry of structure fire resistance performance and collapse resistant capacity and civilian steel framed structure.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is left view of the present utility model;
Fig. 3 is top view of the present utility model;
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 utility model is described further.
The anti-fiery type bean column node of a kind of grooved end plate, in conjunction with Fig. 1 to Fig. 3, comprise steel column 1, girder steel 2, end plate 3 and bolt 4, described girder steel 2 adopts with end plate 3 and docks welding, described end plate 3 is connected by bolt 4 with steel column 1, and described end plate is the grooved end plate, and described bolt is high-strength bolt, described girder steel 2 is i shaped steel or H shaped steel, and described grooved end plate 3 is connected with steel column 1 by grooved extended end plate, grooved flush end plate or grooved web end plate.Described 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, described grooved end plate 3 links to each other with steel column 1 by the edge of a wing of turning up.
Although above-mentionedly by reference to the accompanying drawings the specific embodiment of utility model is described; but be not the restriction to the utility model protection domain; one of ordinary skill in the art should be understood that; on the basis of the technical solution of the utility model, those skilled in the art do not need to pay various modifications that creative work can make or distortion still in protection domain of the present utility model.
