[0022] The present invention will be further described below with reference to the accompanying drawings and embodiments. In the following detailed description, only certain exemplary embodiments of the present invention are described by way of illustration. Undoubtedly, those skilled in the art will recognize that various modifications can be made to the described embodiments without departing from the spirit and scope of the present invention. Therefore, the drawings and description are illustrative in nature and not intended to limit the scope of the claims.
[0023] like Figures 1 to 7As shown in the diagram, the easy-to-install prefabricated fireproof sealing box includes a box frame 1. A rectangular steel plate shell 2 is fixedly installed around the box frame 1 on all four sides and bottom. The length of the rectangular steel plate shell 2 is the same as the length of the sawtooth notch 10 in the floor slab, the width of the rectangular steel plate shell 2 is the same as the width of the sawtooth notch 10, and the height of the rectangular steel plate shell 2 is greater than the depth of the sawtooth notch 10. An avoidance notch 5 is provided at one end of the bottom of the rectangular steel plate shell 2, and an avoidance groove 6 is provided along the length of the other end of the rectangular steel plate shell 2. The rectangular steel plate shell 2 is filled with fireproof rock wool 7. The top of the frame 1 is fixedly installed with a top steel plate 8 for sealing the rectangular steel plate shell 2. Before processing this utility model, the length and width of the sawtooth notch 10 of the floor slab are first measured. Based on the measured length and width dimensions and the requirements of the drawings, the dimensions of each part are obtained. The parts are then processed and manufactured in the factory according to these dimensions. The specific steps are as follows: First, the angle steel is welded into a box frame 1, and the steel plate is processed into a rectangular steel plate shell 2. The two are then welded together, leaving an opening at the top of the box. Fireproof rock wool 7 is then filled into the opening, and the top steel plate 8 is fixedly installed on the top of the box. The fireproof sealing box is then completed. The fireproof sealing box is installed according to its detailed dimensions, corresponding one-to-one with the sawtooth notch 10 on site, and fixed in place to the main steel structure with nails. Fireproof sealant is applied to the overlap and gaps between the fireproof box and the main steel structure to seal them. This utility model utilizes an integrated fireproof sealing box manufacturing process, which saves materials while greatly improving processing and installation efficiency. It is convenient to construct, reduces on-site installation procedures, and avoids material omissions through prefabricated installation. Instead of processing various materials on-site, it transforms them into finished fireproof sealing boxes that arrive on-site, facilitating on-site management, making production more orderly, and ensuring high-quality contract fulfillment.
[0024] like Figure 7 As shown, the box frame 1 includes two parallel, spaced-apart long angle steels 3, symmetrically arranged. Multiple short angle steels 4 are fixedly installed on the opposite surfaces connecting the two long angle steels 3, and these short angle steels 4 are parallel to each other and equally spaced. Both the long angle steels 3 and the short angle steels 4 are galvanized angle steels. The top steel plate 8 is a hot-rolled checkered steel plate, and the rectangular steel plate outer shell 2 is a galvanized steel plate outer shell. The long angle steels 3 and short angle steels 4 have the same shape, only their cut lengths differ. Four short angle steels 4 are preferred, but the number can be selected according to the load-bearing requirements of the top steel plate 8.
[0025] like Figure 1 , Figure 2 and Figure 5 As shown, the clearance notch 5 is a rectangular notch, which is located at the clearance of the curtain wall connector. The rectangular notch is not an exposed opening; it is sealed with the same steel plate as the rectangular steel outer shell 2 to ensure that the fireproof rock wool 7 does not leak out. The purpose is to leave room for the installation of the curtain wall connector.
[0026] like Figure 1 , Figure 2 and Figure 3 As shown, the clearance groove 6 is a rectangular groove that avoids the keel on the main steel structure. The clearance groove 6 runs through the rectangular steel plate shell 2 along the length of the box. The clearance groove 6 is to avoid the keel below. After the clearance groove 6 opens, it is also sealed with the same steel plate as the rectangular steel plate shell 2 to ensure that the fireproof rock wool 7 does not leak out.
[0027] like Figure 4 As shown, an elastic fire-resistant sealing material layer 9 is coated between the top steel plate 8 and the upper surface of the box frame 1. The elastic fire-resistant sealing material layer 9 connects the top steel plate 8 and the box frame 1 and is fixed with steel nails.
[0028] This utility model utilizes an integrated fireproof sealing box manufacturing process, which saves materials while greatly improving processing and installation efficiency. It is convenient to construct, reduces on-site installation procedures, and avoids material omissions through prefabricated installation. Instead of processing various materials on-site, it transforms them into finished fireproof sealing boxes that arrive on-site, facilitating on-site management, making production more orderly, and ensuring high-quality contract fulfillment.
[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
