The embodiment discloses a rock wool board mounting structure, which comprises a steel upright post and an H-shaped steel beam.
The method comprises the following steps of firstly combining an external wall heat preservation construction drawing and a steel structure construction drawing component BIM model, arranging U-shaped connecting pieces at corresponding steel beam column positions in the model, completing simulated arrangement of rock wool boards, and utilizing materials to the maximum extent through reasonable layout to generate a layout drawing of the U-shaped connecting pieces.
U-shaped connecting pieces with corresponding specifications are prepared according to the BIM model, and in the embodiment, the U-shaped connecting pieces are made of steel plates with the thickness of 3mm and comprise two parallel side walls and an abdominal wall perpendicular to the two side walls. This kind of right angle U-shaped connecting piece can be better be fit for the installation of rock wool board, guarantees that this U type connecting piece furthest increases its area of contact with the rock wool board, and then realizes firm card and the effect of reasonable average atress. And because the design is convenient and material-saving, the waste materials of the steel structure processing factory can be selected and then processed, and the resource saving and the cost reduction can be realized to the greatest extent.
In the embodiment, the steel upright is a square box-shaped column with the cross section being 300mm wide, so that the length of the designed U-shaped connecting piece is 300mm; considering the thickness of the rock wool plate and the thickness of the steel member surface which needs to be fireproof and coated with fireproof materials, the groove width is 125mm in the example; on the other hand, because the two side walls are mainly used for clamping and fixing the rock wool board, the two walls need a certain width, in this example, the width of the two arms of the U-shaped groove, namely the groove depth, is designed to be 100mm, and the width/depth can save materials to the maximum extent while well completing the clamping and fixing effects, thereby saving the engineering cost.
After the preparation of the U-shaped connecting piece is completed, the U-shaped connecting piece is welded at a corresponding position on the steel structure beam column according to the arrangement layout of the U-shaped connecting piece. Referring to fig. 1, the length direction of the two side walls of the U-shaped connecting piece is perpendicular to the height direction of the steel upright, and the length of the side wall of the U-shaped connecting piece is consistent with the width of the steel upright, so that after one side wall of the U-shaped connecting piece is attached to the surface of the steel upright and welded, the projection of the U-shaped connecting piece on the surface completely falls on the steel upright, and the two U-shaped end surfaces of the U-shaped connecting piece and the side surface of the steel upright are kept coplanar, thus completing the arrangement of the U-shaped connecting piece perpendicular to the steel upright.

Wherein, because of the confined consideration to the steel stand external corner, the rock wool board that is located on the steel stand adopts crisscross interlocking's construction mode for the rock wool board is more closely knit to the closure of steel stand external corner. Referring to fig. 3, the rock wool boards on one side of one layer are close to the side surface of the steel upright column, extend out of the edge line of the external corner of the steel upright column, the extending part covers the end part of the rock wool board on the other side and does not exceed the external side surface of the rock wool board, the extending side of the rock wool boards on the next layer is changed by the same method, and the rock wool boards on the next layer are alternately reciprocated, and the rock wool boards on the one side of the next layer are mutually staggered to form an interlocking structure.
And then fixing the cement calcium silicate board on the U-shaped connecting piece. In the embodiment, a rock wool board is sealed by a cement calcium silicate board which is a non-combustible material with the combustion performance of A grade and has the breaking strength of more than or equal to 12 MPa. Because the steel structure beam column can not adopt the fixing method of drilling and tapping in the bolt, the influence on the bearing and the safety of the steel structure is avoided, the method of fixing the cement calcium silicate board on the U-shaped connecting piece by the dovetail wire is adopted, the cement calcium silicate board is fixed by the dovetail wire on each U-shaped connecting piece, and the fixing firmness of the steel structure beam column is ensured to the maximum extent. On the one hand, avoided direct fixed unfavorable place of having taken on steel construction beam column, on the other hand for the application of force of cement calcium silicate board is accepted to U type connecting piece, prevents its harm to the rock wool board.
