Description

A kind of cross coupled column

【Technical field】

It the utility model is related to a kind of building element, and in particular to a kind of cross coupled column, belong to architectural engineering technology Field.

【Background technology】

Steel-concrete part combined member is 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 1 ', as shown in Figure 1.This combined member, which has, to be held The advantages that power is big, rigidity is big, fire resistance is good is carried, current this component is not applied also in China.

Bending rigidity ratio of the part coupled column that conventional H profile steel component concrete filled is formed in the weak direction of principal axis in section Strong direction of principal axis is much smaller, and this part coupled column is by being typically weak axle unstability around pillar during axle pressure.In order to meet pillar The requirement of 4 ' bearing capacities, it is common practice to increase the width of the edge of a wing 2 ' of pillar, this may result in the edge of a wing protrusion of pillar 4 ' Wall 3 ', as shown in Fig. 2 influenceing building usable floor area and building attractive in appearance.

Therefore, in order to solve the above technical problems, a kind of cross coupled column it is necessory to provide innovation, existing to overcome The defect in technology.

【Utility model content】

To solve the above problems, the purpose of this utility model is to provide a kind of simple in construction, intensity is high and does not expose wall The cross coupled column of body.

To achieve the above object, the technical scheme that the utility model is taken is：A kind of cross coupled column, it includes cross Steel column, the cross steel column are made up of two H profile steel posts being arranged in a mutually vertical manner；Each H profile steel post includes web, Yi Jishe Put on web both ends and and the vertical edge of a wing of web；In the web of the middle part of the web of the H profile steel post and another H profile steel post The perpendicular setting in portion；Concrete is filled between the edge of a wing of the H profile steel post.

Cross coupled column of the present utility model is further arranged to：The size of described two H profile steel posts is identical, can also Differ.

Cross coupled column of the present utility model is further arranged to：Vertical muscle is embedded with the concrete.

Cross coupled column of the present utility model is also configured to：The tie-rod vertical with the edge of a wing is welded with the edge of a wing.

Compared with prior art, the utility model has the advantages that：

1. it uses two orthogonal H profile steel posts, bending rigidity of the pillar section in weak direction of principal axis can be improved, is carried The capacity under axial of high part coupled column, reduce the design width on the pillar edge of a wing, accomplish that pillar does not expose wall.

2. web is wrapped up by concrete, web part can remove fireproof coating from.

3. it is simple in construction, it is easy to make.

【Brief description of the drawings】

Fig. 1 is the sectional drawing of the steel-concrete combined member of prior art.

Fig. 2 is the connection diagram of the component and wall in Fig. 1.

Fig. 3 is the profile of cross coupled column first embodiment of the present utility model.

Fig. 4 is the connection diagram of Fig. 3 cross coupled column and wall.

Fig. 5 is the profile of cross coupled column second embodiment of the present utility model.

【Embodiment】

Refer to shown in Figure of description 3 and accompanying drawing 4, it is a kind of the first reality of cross coupled column of the present utility model Mode is applied, it includes a cross steel column 1, and the cross steel column 1 is made up of two H profile steel posts 2 being arranged in a mutually vertical manner.

In the present embodiment, the size of described two H profile steel posts 2 is identical, can also differ.

Each H profile steel post 2 includes web 21, and is arranged on the both ends of web 21 and and the vertical edge of a wing 22 of web 21.The H The perpendicular setting in middle part of the web 21 of the middle part of the web 21 of steel column 2 and another H profile steel post 2.

Concrete 3 is filled between the edge of a wing 22 of the H profile steel post 2, web 21 is wrapped up by concrete, and the part of web 21 can be with Remove fireproof coating from.

Further, the tie-rod 23 vertical with the edge of a wing 22 is welded with the edge of a wing 22, tie-rod 23 is used for the drawknot edge of a wing 22, And the concrete 4 filled in constraint.

For cross part coupled column of the present utility model when being connected with wall 6, it does not expose wall 6, such as the institute of accompanying drawing 4 Show.

Referring to shown in Figure of description 5, it is a kind of second embodiment of cross coupled column of the present utility model, It is in place of itself and the difference of first embodiment：Vertical muscle 4 is embedded with the concrete 3, so as to improve the carrying of coupled column Power.

Cross part coupled column of the present utility model is combined using two orthogonal H profile steel posts 2, can be improved pillar and be cut Face weak direction of principal axis bending rigidity, improve part coupled column capacity under axial, reduce the design width on the pillar edge of a wing 22, Accomplish that pillar does not expose wall.

Cross part coupled column of the present utility model is prefabricated in the factory when making and completes steel column, then formwork supporting plate, 22, the edge of a wing concrete perfusion 3 of cross steel column is simultaneously conserved.

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.
