Description

Technical Field

[0001] This invention belongs to the field of construction, and in particular relates to a construction method for an ALC wall panel side box column and fireproof board structure. Background Technology

[0002] Due to the poor fire resistance of steel, reliable fire protection measures must be taken for steel structures to improve the fire resistance of steel structural components and the overall structure. Currently, among the fire protection measures for steel structures, the direct cladding method is the most commonly used in engineering due to its simplicity, good protective performance, and economic cost. The most widely used direct cladding methods are fire-retardant coatings and fire-retardant boards. Fire-retardant boards can serve not only as fire-resistant structures but also as decorative surfaces. The application of a structure combining fire-retardant coatings, fire-retardant boards, and precast wall panels is becoming increasingly common. This structure places extremely high demands on architectural design and construction, requiring compliance with fire protection and functional requirements, as well as stringent spatial requirements. To meet the requirements of both spatial and aesthetic design, the finished surfaces of the fire-retardant boards and precast wall panels must be consistent, and the finished surface of the structural components should be compressed as much as possible to meet spatial requirements. Furthermore, fire-retardant boards are generally installed after the fire-retardant coating and precast wall panels. Before installation, consideration must be given to protecting the finished fire-retardant coating and wall panels to minimize damage to the fire-retardant coating and avoid subsequent repairs that could affect the overall fire resistance requirements of the structure. Existing technologies require welding horizontal and vertical keels, which takes up a lot of space, and welding may damage the fireproof coating, making it difficult to meet the above requirements. Summary of the Invention

[0007] (3) The inside corner of the angle steel vertical main keel is tightly covered with fireproof coating, and the inside corner edge is fixed to the side support of the square steel;

[0008] (4) The grooved surfaces of multiple C-shaped steel horizontal keels face the side box column and are embedded with fireproof coating. At least one end of each C-shaped steel horizontal keel is inserted into a square steel lateral support, and the back of the C-shaped steel horizontal keel is fixed to the square steel lateral support.

[0009] (5) The fireproof plate is fixed with the angle steel vertical main keel, the C-shaped steel horizontal keel and the ALC wallboard.

[0010] Further, in step (2), the square steel lateral support at the lower end is also fixed with the floor keel; in step (3), the angle steel vertical main keel is also fixed with the ceiling keel; in step (5), the fireproof plate is also fixed with the ceiling keel and the floor keel.

[0011] Further, the plurality of square steel lateral supports are respectively welded with the side box columns; the floor keel is fixed with the square steel lateral support by using self-tapping screws, and the floor keel is fixed with the concrete floor by using nail shooting; the back of the C-shaped steel horizontal keel is fixed with the square steel lateral support by using self-tapping screws; the angle steel vertical main keel is fixed with the square steel lateral support by using self-tapping screws; the angle steel vertical main keel is connected with the ceiling keel by welding; the ceiling keel is connected with the lower flange of the steel beam by welding; the fireproof plate is fixed with the angle steel vertical main keel, the C-shaped steel horizontal keel, the ceiling keel and the floor keel by using self-tapping screws.

[0012] Further, the side box column comprises a first surface, a second surface, a third surface and a fourth surface connected in sequence;

[0013] Two ALC wallboards are connected to the first surface and the third surface respectively, and the two ALC wallboards protrude from the fourth surface;

[0014] The number of the fireproof plates is two, including a concave fireproof plate and a plate-shaped fireproof plate, the concave fireproof plate covers the second surface and partially covers the first surface and the third surface, and the two ends of the concave fireproof plate are fixed on the two ALC wallboards respectively; the plate-shaped fireproof plate covers the fourth surface, the two ends of the plate-shaped fireproof plate are fixed on the two ALC wallboards respectively, and the surface of the plate-shaped fireproof plate is flush with the surface of the ALC wallboard.

[0015] Further, the ALC wallboard and the fireproof plate are connected at the internal corner by using an internal corner edge sealing keel, the internal corner edge sealing keel is fixed with the ALC wallboard by using expansion screws, the ALC wallboard and the fireproof plate are connected at the external corner by using an external corner edge sealing keel, and the external corner edge sealing keel is fixed with the ALC wallboard and the square steel lateral support by using self-tapping screws.

[0016] Further, a plurality of square steel lateral supports are respectively arranged at the side of the first surface close to the second surface, the side of the second surface close to the first surface, the side of the second surface close to the third surface, the side of the third surface close to the second surface and the two sides of the fourth surface close to the first surface and the third surface, and the plurality of square steel lateral supports are also distributed in the vertical direction; the number of the angle steel vertical main keels is two, and the angle steel vertical main keels are respectively arranged at the included angle between the first surface and the second surface and the included angle between the second surface and the third surface.

[0018] Beneficial effects: Compared with the prior art, the following beneficial effects are achieved:

[0019] Firstly, the square steel lateral support is embedded in the fireproof paint as a lateral support connection. The C-shaped steel cross beam is also embedded in the fireproof paint, and it penetrates into a square steel lateral support without occupying the horizontal space. The angle steel vertical main beam is closely attached to the fireproof paint, and only the thickness of the panel of the angle steel vertical main beam protrudes from the fireproof paint, so that no additional space is occupied, and the fireproof plate is compressed to complete the surface, so as to ensure the width requirement of the building walkway. For example, if the specification of the square steel lateral support is 35*35 mm, the specification of the angle steel vertical main beam is 50*50*3 mm, and the thickness of the fireproof paint is 30 mm, the distance of the fireproof plate protruding from the fireproof paint is 8 mm.

[0020] Secondly, the fireproof paint is made first, and the fireproof plate beam is made later. The fireproof plate beam is mainly riveted by self-tapping screws. Only the square steel lateral support is welded with the side box column, and the angle steel vertical main beam is welded with the top beam. The top beam is welded with the lower flange of the steel beam, so as to reduce the overall welding operation and the damage of the fireproof paint of the steel column caused by the installation of the fireproof plate beam.

[0021] Thirdly, the top and bottom beams are added into the connection system of the present application to ensure the overall stability of the fireproof plate. BRIEF DESCRIPTION OF DRAWINGS
