Background
In the building that post, roof beam, roofing are the steel construction, need surpass the 500 mm's of roofing prerequisite in preventing hot wall, the mode in the past adopts to prevent hot wall and is located under the roofing girder steel at indoor part, prevents hot wall on the roofing girder steel and need do alone in addition, prevents that hot wall material is block wall or light gauge steel PLASTIC LAMINATED wall body. Adopt the blockwork body construction to need wet work, construction work volume is big, and the blockwork wall can't have reliable connection with the girder steel on the girder steel, and the outdoor weatherability of light gauge steel PLASTIC LAMINATED wall body is poor, and the roofing purlin of above mode or the roofing girder steel of another direction all will pass and prevent hot wall, causes local weak link of preventing fires, brings the fire prevention hidden danger.
Therefore, a firewall type and installation construction mode which are relatively simple and convenient in construction, capable of reducing wet operation workload, good in weather resistance and free of fireproof weak links are needed at present.
SUMMERY OF THE UTILITY MODEL
The utility model aims to provide a fireproof wall structure which is relatively simple and convenient to construct, reduces the workload of wet operation, has good weather resistance and does not have fireproof weak links.
In order to solve the technical problems, the technical scheme of the utility model is to provide an ALC plate firewall roofing structure, which is characterized in that: the ALC board is installed to the roofing as preventing hot wall from the indoor floor, the two sides of the ALC board are provided with structural steel columns and structural steel beams, the ALC board is fixedly connected with the structural steel columns or the structural steel beams through angle steel and bolts, and the roofing part of the ALC board is provided with a covering metal plate.
Preferably, the ALC plate is connected with the structural steel column or the structural steel beam on one side only and is fixed.
Preferably, the ALC board is formed by splicing a plurality of blocks, and the height of each block is not more than 6 m.
Preferably, the ALC board located in the bottom is only connected and fixed with one side structure girder steel in the upper end.
Preferably, the upper end and the lower end of the ALC plate except the ALC plate positioned at the bottom are connected and fixed with the structural steel beam on one side.
Preferably, the ALC panel has a height above the roof of at least 500 mm.
Preferably, the structure steel column, the structure girder steel, the angle steel and the bolt surface that the structure used all are equipped with the fire retardant coating picture layer.
The utility model has the advantages that the ALC board (autoclaved lightweight concrete board) is used as a firewall and is installed from the floor of an indoor building to a roof, wherein the ALC board is used as the firewall, structural steel columns and steel beams are respectively arranged at two sides of the ALC board, angle steel and bolts are used for fixing the ALC board, and the roof is used for covering the metal plate of the ALC board.
Due to the application of the technical scheme, compared with the prior art, the utility model has the following advantages:
the ALC board is the finished product, simple to operate does not need wet operation, and the construction is simple and convenient, and ALC board both sides set up structural steel post, girder steel, and the ALC board is connected with one side girder steel side direction, prevents that hot wall can not be interrupted by roofing girder steel or purlin, avoids the fire prevention hidden danger, and the ALC board can be used for outdoor, and the weatherability is good.
Drawings
FIG. 1 is a schematic view of the structural mounting configuration of the present invention;
reference numerals: 1. a building floor; 21. 22, ALC board; 3. a structural steel column; 41. 42, structural steel beams; 51. 52, 53, connecting angle steel; 6. fixing the bolt; 7. a steel structure roof; 81. 82, metal plate.
Detailed Description
In order to make the utility model more comprehensible, preferred embodiments are described in detail below with reference to the accompanying drawings.
Examples
As shown in fig. 1, the ALC board 21 is erected on the floor, and when the required total height of the firewall exceeds 6m, the ALC board 22 is installed on the ALC board 21, and the number of ALC boards 22 is determined according to the total height of the firewall, and each height does not exceed 6 m. The positions of the structural steel columns 3 and the structural steel beams 41 and 42 on the two sides are determined according to the thicknesses of the ALC boards 21 and 22, and the minimum clear distance is equal to the height of the ALC boards. When the ALC board is one, the ALC board 21 is fixedly connected with the structural steel beam 41 of the roof through angle steel 53 and bolts 6 and is not less than 500mm higher than the steel structure roof 7, and the part out of the roof is covered by metal plates 81 and 82 to play a role in water prevention. When the ALC board adopts two or more than two, ALC board 21 is connected and fixed with structural steel beam 42 through angle steel 51 and bolt 6, ALC board 22 is installed on ALC board 21, the lower end is connected and fixed with structural steel beam 42 through angle steel 52 and bolt 6, the upper end is connected and fixed with structural steel beam 41 of the roof through angle steel 53 and bolt 6, and is not less than 500mm higher than steel structural roof 7, and the part out of the roof is covered with metal plates 81 and 82 to play a role in water proofing. The structural steel column 3, the structural steel beams 41 and 42, the angle steels 51, 52 and 53 and the bolts 6 for connecting and fixing the ALC boards 21 and 22 are coated with fireproof paint on the surfaces, so that the fireproof limit of the structural steel column is equal to that of a fireproof wall.
The ALC board (autoclaved lightweight concrete board) is used as a firewall and is installed to a roof from the ground of an indoor building, wherein the ALC board is used as the firewall, structural steel columns and steel beams are respectively arranged on two sides of the ALC board, angle steel and bolts are used for fixing the ALC board, and the roof is used for covering a metal plate of the ALC board. The fire-proof wall has the characteristics of convenience in installation, no need of wet operation, simplicity and convenience in construction, no possibility of breaking a fire-proof wall by a roof steel beam or a purline, avoidance of fire-proof hidden danger, capability of being used outdoors and good weather resistance.
The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention.
