Description

A kind of coupled column for exempting from fireproof coating
【Technical field】
It the utility model is related to a kind of building element, and in particular to a kind of coupled column for exempting from fireproof coating, belong to building work Journey technical field.
【Background technology】
Steel construction is under high temperature of fire effect, and its mechanical property can be raised and declined with temperature, therefore, in steel construction all Structure can be taken precautions against fire.Common fire prevention measure is to give Spray For Anti-corrosion of Steel Structures fireproof coating, however fireproof coating price compared with Height, the cost of building can be caused higher using fireproof coating.
Steel-concrete part group and component are a kind of new structural members of 1980s Europe proposition, its The basic pattern in section is the fill concrete between the edge of a wing of H profile steel component.This combined member has that bearing capacity is big, rigidity Greatly, the advantages that fire resistance is good, there is no practical application also at home at present.
Therefore, in order to solve the above technical problems, a kind of coupled column for exempting from fireproof coating it is necessory to provide innovation, with gram Take the defect of the prior art.
【Utility model content】
To solve the above problems, the purpose of this utility model is to provide a kind of simple in construction, fire protecting performance is good, and cost is low The coupled column for exempting from fireproof coating.
To achieve the above object, the technical scheme that the utility model is taken is：A kind of coupled column for exempting from fireproof coating, it is wrapped Include steel-concrete part coupled column and fire-proof plate；Wherein, steel-concrete part coupled column includes H profile steel and filling In the concrete in H profile steel；The H profile steel is by web, and is arranged on web both ends and is formed with the vertical edge of a wing of web；Institute Concrete Filled is stated between the edge of a wing, the edge of a wing of H profile steel is protruded in its outward flange；The fire-proof plate is arranged at the outer of two side wing edges Portion；The width of the fire-proof plate is more than the width on the H profile steel edge of a wing, be H profile steel web thickness and web both sides concrete width it With.
The coupled column of the present utility model for exempting from fireproof coating is further arranged to：Tie-rod is welded between the edge of a wing.
The coupled column of the present utility model for exempting from fireproof coating is further arranged to：It is embedded with the concrete some vertical Muscle, length direction extension of the vertical muscle along coupled column.
The coupled column of the present utility model for exempting from fireproof coating is further arranged to：The fire-proof plate is connected with the edge of a wing by mortar Connect；There is space between the fire-proof plate and the concrete for protruding the edge of a wing, the second mortar is filled with space.
The coupled column of the present utility model for exempting from fireproof coating is also configured to：The length of the fire-proof plate is not less than coupled column Length.
Compared with prior art, the utility model has the advantages that：
1. in coupled column the side wing edge of H profile steel two by coupled column it is interior filling concrete, fire-proof plate and after pour mortar parcel, H The web of shaped steel is wrapped up by the interior filling concrete in coupled column；I.e. in coupled column, H profile steel is completely wrapped, can be with fire Isolate well with thermal source.
2. compared with traditional clean steel column, exempt from fireproof coating, reduce construction costs, there is good economic benefit.
3. simple in construction, cost is low.
【Brief description of the drawings】
Fig. 1 is the profile of the steel-concrete part coupled column in the coupled column of the present utility model for exempting from fireproof coating.
Fig. 2 is the structural representation of the coupled column of the present utility model for exempting from fireproof coating.
【Embodiment】
Refer to shown in Figure of description 1 and accompanying drawing 2, the utility model is a kind of coupled column for exempting from fireproof coating, its by A few part compositions such as steel-concrete part coupled column 1 and fire-proof plate 2.
Wherein, steel-concrete part coupled column 1 includes H profile steel 3 and the concrete 4 being filled in H profile steel 3.Institute H profile steel 3 is stated by web 31, and is arranged on the both ends of web 31 and the edge of a wing 32 vertical with web 31 and forms.The concrete 4 is filled out Fill between the edge of a wing 32, the segment distance of the edge of a wing 32 1 of H profile steel 3, such as Fig. 1 are protruded in the outward flange of concrete 4.
Further, tie-rod 33 is welded between the edge of a wing 32, tie-rod 33 is used to fill in the drawknot edge of a wing 32, and constraint Concrete 4.Some vertical muscle 34 are embedded with the concrete 4, length direction of the vertical muscle 34 along coupled column 1 extends, with Improve the structural strength for renting zygostyle 1.
The fire-proof plate 2 is arranged at the outside of two side wing edges 32, and the width of fire-proof plate 2 is more than the width on the H profile steel edge of a wing 21, For the thickness of H profile steel web 31 and the width sum of 31 both sides concrete of web 4, such as Fig. 2.Specifically, the fire-proof plate 2 and the edge of a wing 32 are connected by mortar 5, make fire-proof plate 2 that the outer surface of the width of the post edge of a wing 32 be completely covered.Mortar 51 covers the H profile steel edge of a wing The outer surface of 32 thickness directions.The length of the fire-proof plate 2 is not less than the length of coupled column 1, and the width of fire-proof plate 2 is more than group The width of the side wing edge 32 of zygostyle two, is H profile steel web thickness and web both sides concrete width sum, the thickness root of fire-proof plate 2 Need to choose according to the specific fire prevention of building.
There is space between the fire-proof plate 2 and the concrete 4 for protruding the edge of a wing 32, the second mortar is filled with space 52。
The construction method of the coupled column of the present utility model for exempting from fireproof coating is as follows：Steel-concrete part coupled column 1 is in work The prefabricated completion of factory, the segment distance of the edge of a wing one of the outward flange protrusion H profile steel of concrete filled, and H profile steel web both sides concrete pair Claim, such as Fig. 1.
Mortar 51 is spread in the outer surface of the width of two side wing edges 32 of post 1 and then sticks fire-proof plate 2, fire-proof plate 2 Concrete filled in width with web both sides flushes.
After having pasted fire-proof plate 2, the second mortar 52 is spread again in the space of fire-proof plate 2 and concrete filled so that interior Concrete, the second mortar 52, fire-proof plate 2 is filled out to flush.
3 liang of side wing edges 32 of H profile steel of the coupled column of the present utility model for exempting from fireproof coating are by interior filling concrete 4 in coupled column Wrapped up with fire-proof plate 2, the web 31 of H profile steel 3 is wrapped up by the interior filling concrete 4 in coupled column；I.e. in coupled column, H profile steel is complete Full parcel, can be very good to isolate with thermal source under fire.
Embodiment above is only the preferred embodiment of this creation, all in this wound not to limit this creation Any modification, equivalent substitution and improvements for being done etc. within the spirit and principle of work, should be included in this creation protection domain it It is interior.
