Background

The steel structure column is a column body which is formed by taking steel materials as a main body structure. The steel structure column has the characteristics of simple and convenient construction, can be connected with each component through modes such as welding seams, bolts or rivets, has the shortcoming of easy bending when the steel structure column is too thin, and when the steel structure column is too thick, although the steel structure column is difficult to bend, but the bearing capacity of the steel structure column is far beyond the bearing capacity of the steel structure column when the steel structure column is too thin, but the steel that the steel structure column used this moment is more, causes the waste of steel, increases the cost. In addition, the steel of the steel structure column has poor fire resistance, and the pure steel of the steel frame building structure and the large-span roof steel structure building is easy to suffer from large-area fire disasters and cause great loss, so the fire prevention measures of the steel structure column are very important, and in the prior art, the steel structure column only depends on the surface of the column to be sprayed with a fire-proof coating, and the fire prevention effect is unsatisfactory.

SUMMERY OF THE UTILITY MODEL

The utility model discloses to prior art's not enough, provide a fire prevention profiled steel structure post that simple structure is reasonable, solved the not enough and not enough problem of fire behavior of current steel structure post intensity.

The technical scheme of the utility model is realized like this: the utility model provides a fire prevention type steel structure post, includes the circular shape steel structure post, its characterized in that still including fixing at the inside trident shape support column of steel structure post and installing at the outside fire protection sleeve pipe of steel structure post, its inner wall of steel structure post is equipped with the direction muscle, and its outer wall is connected with the bar constant head tank, be equipped with on the support column with direction muscle assorted fixed slot, the support column passes through the fixed slot and pegs graft the back welding at steel structure post inner wall with the direction muscle, and the fire protection sleeve pipe cup joints at steel structure post outside through the rib and the bar constant head tank grafting back of inner.

The strip-shaped positioning grooves are at least three and are uniformly distributed on the outer wall of the steel structure column through screw connection or welding.

And the surface of the steel structure column is sprayed with a fireproof coating.

The fireproof coating is a polyolefin fireproof insulating coating or a modified high-chlorine polyethylene fireproof coating with the thickness of 1-2 mm.

The fireproof sleeve is a silicon rubber glass fiber sleeve.

The thickness of the support column is 0.8-1.1 times of the thickness of the steel structure column.

The utility model provides an existing defect among the background art, have following beneficial effect:

the utility model provides a fire prevention shaped steel structure post simple structure is reasonable, provides a fire prevention shaped steel structure post that simple structure is reasonable, has solved current steel structure post intensity not enough, the problem of flexible deformation, and fire behavior is good. The utility model discloses a welding trident shape support column on steel structure column inner wall makes support column and steel structure column even as an organic whole, shares load, under the prerequisite that does not increase the thickness of steel plate, has improved steel structure column load-carrying capacity, the effect of reinforcing steel structure column intensity. The fireproof sleeve is connected to the outside of the steel structure column in a sleeved mode through the insertion of the strip-shaped positioning grooves and the ribs, can be used at the high temperature of 200-280 ℃ for a long time, is good in fireproof performance, and meets the fireproof requirement of a building steel structure.

Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

As shown in fig. 1, fig. 2, a fire prevention type steel structure column embodiment that fig. 3 and fig. 4 show, including circular shape steel structure column 1, fix at 1 inside trident shape support column 2 of steel structure column and install at 1 outside fire protection sleeve 3 of steel structure column, 1 its inner wall of steel structure column is equipped with direction muscle 4, its outer wall is connected with bar constant head tank 6, be equipped with on the support column 2 with direction muscle 4 assorted fixed slot 5, support column 2 is pegged graft the back through fixed slot 5 and direction muscle 4 and is welded at 1 inner wall of steel structure column, fire protection sleeve 3 is pegged graft the back through the rib 7 and the bar constant head tank 6 of inner wall, cup joint at 1 outside of steel structure column.
