Furthermore, the terms "first", "second" and "first" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of the invention, "a plurality" means two or more unless specifically limited otherwise.
In the present invention, unless otherwise expressly specified or limited, the terms "mounted," "connected," "secured," and the like are to be construed broadly and can, for example, be fixedly connected, detachably connected, or integrally connected; can be mechanically or electrically connected; they may be connected directly or indirectly through intervening media, or they may be interconnected between two elements. The specific meaning of the above terms in the present invention can be understood by those of ordinary skill in the art according to specific situations.
As shown in fig. 1, the present invention provides a portable lower-hanging fire prevention plate for a super high-rise building, comprising: a hanging rack 1 and a fire-proof plate 2, when the structure is used, the hanging rack 1 is fixed on the outer vertical surface of the building edge structure 100, the fixing position depends on the structural shape of the hanging rack 1, the lower end of the hanging rack 1 is connected with the fire-proof plate 2, so that the fire-proof plate 2 is hung below the lower edge of the building edge structure 100 to enhance the fire-proof function of the building. The thickness of the fireproof plate 2 can adopt a steel plate (Q235B) with the thickness of 6mm, meanwhile, the hanging height is determined according to a structural entity, the height is generally 600-900mm, and the length of the fireproof plate also needs to be deepened in a segmented mode according to the boundary line of an actual engineering structure.
The further improvement is that angle steel 3 is arranged on the lower edge of the fireproof plate 2. L50 is 5 the angle steel 3 in this embodiment, and its length and PLASTIC LAMINATED are the same length, and this angle steel install do benefit to down hang the whole stable and follow-up indoor furred ceiling of PLASTIC LAMINATED and receive first process.
The fire-proof plate 2 is further improved in that a fire-proof layer is coated on the fire-proof plate. After the lower-hanging fireproof plate is installed, the fireproof plate is coated with fireproof paint with the thickness of not less than 25mm (the fireproof limit is at least 3 hours) on site to form a fireproof layer in a full covering mode. During indoor construction, a movable frame with a transverse cantilever structure can be adopted to assist construction.
The further improvement is that the thickness of the fireproof layer is not less than 25mm.
In a further development, at least two hangers 1 are connected to each of the fire protection plates 2, in order to facilitate a stable connection of the fire protection plates.
In one embodiment, the improvement is that the hanging rack 1 is a straight channel steel, and the upper end of the straight channel steel is fixedly installed on the outer vertical surface of the building edge structure 100 through bolts, namely, the hanging rack 1 is vertically fixed on the outer vertical surface.
In another embodiment, as shown in fig. 2, the hanger 1 is further modified to be an L-shaped hanger, the L-shaped hanger 1 is hung upside down on a building edge structure 100, a transverse portion 11 of the L-shaped hanger 1 is fixedly mounted on the upper surface of the building edge structure 100 by bolts, a vertical portion 12 of the L-shaped hanger 1 extends downwards along the outer vertical surface of the structure 100, and the lower end of the vertical portion 12 of the L-shaped hanger 1 is connected to the fire-proof plate 2. The horizontal part of this L type stores pylon and vertical part's coupling part adopt horizontally butt weld to connect for improve the overall structure stability of stores pylon.
Because the thickness of the connecting part of the hanging rack and the fireproof plate is increased, if the connecting part of the hanging rack and the fireproof plate is positioned on the outer vertical surface part of the building along the structure, the lower end of the vertical part of the hanging rack is inclined outwards, so that the fireproof plate is also inclined, the whole structure is not attractive, and the difficulty is increased for the subsequent indoor suspended ceiling installation process; simultaneously, also can cause the influence to the stability that the stores pylon is connected fixedly, influence its life. In order to solve the problem, the technical scheme is further improved in that the lower end of the vertical part 12 of the L-shaped hanging rack 1 exceeds the lower edge 110 of the building edge structure 100, and the connection part of the fire prevention plate 2 and the hanging rack 1 is positioned below the lower edge of the building edge structure 100.
Hang the work progress of PLASTIC LAMINATED under, for avoiding leading to it to drop because of misoperation, simultaneously, improve the installation effectiveness, the further improvement of this embodiment is, the L type be equipped with a hanging hole 13 on the horizontal part 11 of stores pylon 1 for connect safety rope 4, when hanging the PLASTIC LAMINATED installation under, carry out the tractive protection to the structure through safety rope, it can to remove safety rope after the construction.
In another aspect, the present invention provides a construction method of a portable lower hanging fireproof plate for a super high-rise building, including the following steps:
manufacturing a hanging frame by welding channel steel;
transporting the hanging rack and the fireproof plate to a construction site;
fixing the fireproof plate on the hanging frame through bolts;
the hanging rack provided with the fireproof plate is fixed on a building edge structure through bolts with the assistance of a safety rope;
removing the safety rope;
and coating a fireproof layer on the fireproof plate.
The portable lower-hanging fireproof plate for the super high-rise building and the construction method thereof can greatly enhance the fireproof design on the basis of the fireproof measures of the original super high-rise building, not only does not change the original design, but also has convenient transportation and simpler construction;
the whole lower-hanging fireproof plate is very simple in structure, channel steel, angle steel, steel plates, bolts and the like which form the parts can be manufactured and finished in a processing factory, and only simple assembly and anchoring installation are needed after the finished product is transported to the site, so that the construction cost is greatly saved;
the construction method adopts the post-embedded steel bar anchoring technology, compared with the embedded steel plate, the field implementation flexibility is good, the deepening of the curtain wall of a general project is completed relatively at the later stage, and the ultra-high layer with the building height of more than 250 meters has the characteristics of long construction period, high floor height, multiple layers, high requirement on the visual effect of the outer vertical surface, complex stress on the structure edge receiving and the like;
