Abstract
The utility model provides a steel column with a fireproof protection facility. The steel column comprises an H-shaped steel column, and the periphery of the H-shaped steel column is coated with an inner non-inflammable board layer and an outer non-inflammable board spliced in a staggered mode successively. Meanwhile, the out sides of four corners of the inner non-inflammable board layer on the top flange and the bottom flange of the H-shaped steel column are respectively provided with an angle channel along the longitudinal direction of the steel columns, and splicing strips are arranged at the inner side of the splicing portion of two non-inflammable board layers on both sides of a web board of the H-shaped steel column. Because the A1 grade non-inflammable board (asbestos-free low-density fiber reinforced calcium silicate board) is adopted and has components similar to marble and granite and large size and width, the strength and the fireproof property of the steel column can be greatly improved by using the non-inflammable board as the fireproof protection layer of the steel column. The fireproof protection layer is more reliable than the fireproof coating, the service life of the steel column is similar to that of cement concrete and is more than 50 years, and the use requirements can be fully satisfied.

For realizing above-mentioned purpose; The technical scheme that the utility model provided is: a kind of steel column structure with flameproof protection facility; It includes steel I-column; Be surrounded by an internal layer fireproof board and an outer fireproof board of fissure of displacement splicing successively in the periphery of steel I-column; Simultaneously outside four jiaos of the internal layer fireproof boards of the top flange of steel I-column and bottom flange, vertically be respectively equipped with a horned dinosaur bone, and be provided with the seam lath in the two-layer fireproof board edge joint position inboard of the web both sides of this steel I-column along steel column.
It is fixing all to adopt the self-tapping screw of equidistance to be connected between described internal layer fireproof board and horned dinosaur bone and the outer fireproof board, and plate seam place and screw hole place all adopt filleting putty to smear to stitch and fill and lead up processing.
Described internal layer fireproof board and outer fireproof board are no asbestos low-density fibre and strengthen calcium silicate board, are to synthesize with silica and calcium oxide, cellulose fibre.
Described internal layer fireproof board and outer fireproof board are spliced by multi-sheets.
Described steel I-column is a 140b standard steel I-column.
Described horned dinosaur bone is of a size of L30 * 0.5mm.
The thickness of described internal layer fireproof board is 20mm, is formed by the board material splice of two 2440 * 440 * 20mm, two 2440 * 140 * 20mm, two 360 * 440 * 20mm, two 360 * 140 * 20mm.
The thickness of described outer fireproof board is 12mm, is formed by the board material splice of two 2440 * 464 * 12mm, two 2440 * 184 * 12mm, two 360 * 464 * 12mm, two 360 * 184 * 20mm.
Described seam lath is of a size of 100 * 380 * 20mm.
The utility model is after having adopted such scheme, because the utility model adopts A
1Level fireproof board (no asbestos low-density fibre strengthens calcium silicate board); Its composition is similar to marble, granite, and the specification breadth is big, so the fireproof jointing sheath of this fireproof board as steel column; Can make that intensity, the fire resistance of the utility model are improved greatly; More reliable than fireproof paint, and make that the service life of the utility model is close with cement concrete＞50 years, can satisfy instructions for use fully.
Description of drawings
Fig. 1 is the front view of the utility model.
The specific embodiment
Below in conjunction with specific embodiment the utility model is further specified.
Shown in accompanying drawing 1; The described steel column structure of present embodiment with flameproof protection facility; It includes 140b standard steel I-column 1; Wherein, The outer fireproof board 3 (board material splice by two 2440 * 464 * 12mm, two 2440 * 184 * 12mm, two 360 * 464 * 12mm, two 360 * 184 * 20mm forms) that an internal layer fireproof board 2 that a 20mm who is surrounded by successively in the periphery of steel I-column 1 is thick (board material splice by two 2440 * 440 * 20mm, two 2440 * 140 * 20mm, two 360 * 440 * 20mm, two 360 * 140 * 20mm forms) and a 12mm are thick, fissure of displacement splicing between this internal layer fireproof board 2 and the outer fireproof board 3; Simultaneously outside 2 four jiaos of the internal layer fireproof boards of the top flange of steel I-column 1 and bottom flange 20mm, vertically be respectively equipped with a L30 * 0.5mm horned dinosaur bone 4, and be provided with seam lath 5 in the two-layer fireproof board edge joint position inboard of the web both sides of this steel I-column 1 and (be of a size of 100 * 380 * 20mm) along steel column.In addition; It is fixing to adopt M4 * 30mm self-tapping screw to connect between described internal layer fireproof board 2 of the utility model and the horned dinosaur bone 4; It is fixing to adopt M4 * 35mm self-tapping screw to connect between internal layer fireproof board 2 and the outer fireproof board 3; The screw spacing is 200mm, and the utility model at plate seam place and the screw hole place all adopt filleting putty to smear seam to fill and lead up processing.Also have the described internal layer fireproof board 2 of the utility model to be no asbestos low-density fibre and strengthen calcium silicate board with outer fireproof board 3; Be with silica and calcium oxide, cellulose fibre; Be pressed into high temperature, high pressure, the following steaming; Its main synthetic is the crystallization of holder shellfish mullite, so its stable performance, light weight, intensity is high, coefficient of thermal conductivity is low, it is greatly A that specification is opened the width of cloth
