Abstract
Description
Technical Field
[0001] This invention belongs to the field of steel structure engineering technology, specifically relating to a sealing structure and method for prefabricated steel structure houses. Background Technology
[0002] With the continuous development of prefabricated steel structure buildings and the gradual increase in the demand for housing functions, some prefabricated steel structure buildings with increased or decreased pressure have put forward higher requirements for indoor sealing measures. At this time, the sealing treatment of the connection points has also emerged, becoming a difficult problem in the building design and construction process. A variety of sealing measures and filling materials have begun to be applied to various building groups that require sealing treatment.
[0003] Currently, most prefabricated steel structure houses in my country suffer from various problems in sealing. Common sealing methods include pressing, edge sealing with sealing strips, and caulking with sealant, primarily used for sealing gaps at component overlaps, joints, windows, and door openings. The former is usually completed during component installation, but its disadvantages include high material performance requirements, susceptibility to deformation and displacement during use, significantly impacting lifespan, and its large and thick size negatively affecting the interior aesthetics. The latter mostly uses chemically-based sealants, which, while possessing good elasticity, tensile strength, and high thixotropy, have poor heat and water resistance, making them prone to aging and cracking under such conditions, and emitting a pungent odor, severely affecting usability. Furthermore, both methods involve complex surface cleaning, dust removal, and base brushing processes during preparation, impacting project progress.
[0004] Addressing the shortcomings and deficiencies of current sealing methods such as pressure strips and filler adhesives used in prefabricated steel structure houses, this paper proposes an aesthetically pleasing, durable, and easy-to-install sealing method for prefabricated buildings. This method is essential for further improving the user experience, and its unique panel laying method has broad application prospects. Summary of the Invention
[0005] To overcome the shortcomings of existing technologies, this invention provides a sealing structure and method for prefabricated steel structure houses. The entire construction process ensures that the building and structural systems do not interfere with each other, improving installation efficiency and guaranteeing sealing performance.
[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows:

[0011] The steel plate joints at both ends of the corner building sealing steel plate are welded to the outer steel plate of the floor slab and the outer steel plate of the wall panel, respectively.
[0012] The continuous connecting angle steel is connected to the continuous lap bracket fixed on the box-shaped steel beam by torsion shear type high-strength bolts;

[0021] The prefabricated floor slab grid keel and prefabricated wall panel grid keel are pre-laid with outer steel plates, and have continuous connecting angle steels around them. They are reliably connected to the continuous lap brackets fixed on the box-shaped steel beams by torsion shear type high-strength bolts.

It is understood that "first / second / third" may be interchanged in a specific order or sequence where permitted, so that the embodiments of the present invention described herein can be implemented in an order other than that illustrated or described herein.
[0038] This invention provides a sealing structure and method for prefabricated steel structure houses. The entire construction process does not interfere with the building and structural system, improving installation efficiency and ensuring sealing performance. It adopts an integrated building sealing steel plate, which has a simple structure and is easy to construct. At the same time, this building sealing method is highly practical and suitable for various types of prefabricated steel structure houses with sealing requirements, while also ensuring good aesthetics.
[0039] like Figure 1-7 As shown, the sealing structure of the present invention for prefabricated steel structure houses includes box-type steel beams, prefabricated floor slab grid keel, prefabricated wall panel grid keel and corner building sealing steel plate 10;
[0040] The box-shaped steel beam is connected to a continuous lapped bracket; the corner building sealing steel plate 10 is in the shape of a right angle L and is fixed at the corner of the building; the steel plate joints at both ends of the corner building sealing steel plate 10 are welded to the outer steel plate of the floor slab and the outer steel plate of the wall panel, respectively; the continuous connecting angle steel is connected to the continuous lapped bracket fixed on the box-shaped steel beam by torsion shear type high strength bolts 12;
[0041] In one embodiment, the corner building sealing steel plate 10 is provided with physical filling pores and raised grooves 11. The raised grooves 11 are arc-shaped and protrude outwards.
[0042] In one embodiment, bolt holes are provided on the prefabricated floor slab grid keel and the prefabricated wall panel grid keel edge sealing beam. The reserved bolt holes are standard round holes. The corner building sealing steel plate 10 is fixedly connected to the prefabricated floor slab grid keel and the prefabricated wall panel grid keel through the installation bolts 13 and the bolt holes on the edge sealing beam, thereby fixing it at the corner of the building.
[0043] In one embodiment, solid material is finally filled into the physical filling pores on both sides of the reserved hole to further ensure the quality of the building's airtightness.
[0044] In one embodiment, the raised groove 11 accommodates a torsion shear type high-strength bolt 12.
[0045] In one embodiment, the prefabricated floor slab grid keel and the prefabricated wall panel grid keel are welded together using box-type steel pipes.
[0046] This invention also provides a construction method for a sealing structure in prefabricated steel structure houses, specifically:
[0047] Using the bolt holes pre-drilled in the prefabricated floor slab grid keel and prefabricated wall panel grid keel edge sealing beams, and with the help of equally spaced mounting bolts 13, the corner building sealing steel plate 10, which has pre-set physical filling gaps and protruding grooves 11, is fixed at the corner of the building perimeter using a steel plate laying method. After the corner building sealing steel plate 10 is placed in the designated position, the steel plate is fixed using the washers and nuts provided with the mounting bolts 13. After the corner building sealing steel plate 10 is fixed, the steel plate joint at the end of the corner building sealing steel plate 10 is treated with butt welds to the floor slab outer steel plate and the wall panel outer steel plate. Finally, the physical filling gaps on both sides of the pre-drilled holes are filled with solid material. The surface of the prefabricated floor slab grid keel and prefabricated wall panel grid keel is pre-laid with outer steel plates, and continuous connecting angle steel is pre-set around the perimeter. It is reliably connected to the continuous lap brackets fixed on the box-shaped steel beam by torsion shear type high-strength bolts 12.
[0048] In one embodiment, the following steps are included:
[0049] First, the box-shaped steel pipes are welded together to form prefabricated floor slab grid keels and prefabricated wall panel grid keels. An outer steel plate is welded onto the surface, and then continuous connecting angle steel with pre-drilled bolt holes is welded to the outside of the grid keel edge beam. The outer steel plate ensures a smooth and sealed surface for the panels; the continuous connecting angle steel facilitates the overlapping of the prefabricated panel grid keels, ensuring the finished surface remains flush with the frame beams; and the pre-drilled bolt holes allow for reliable connection to the pre-installed overlapping brackets on the frame beams using high-strength bolts.
[0050] Second, the sheet metal is rolled into an L-shape (for the turning point of the sheet surface) or a three-dimensional spatial structure (for the corner) to form a building sealing steel plate, and protruding grooves, bolt holes and physical filling pores are reserved at the designated locations.
[0051] Third, based on the scale of the prefabricated steel structure house, all the components produced in the above quantities, along with small components such as steel pads and bolts, are transported to the installation site.
[0052] Fourth, use lifting equipment to overlap the prefabricated panel grid keel on site, so that the connecting angle steel corresponds one-to-one with the reserved bolt holes on the overlapping bracket, and then use high-strength bolts to tighten and fix it, so that the node connection is safe and reliable, and ensures the flatness of the floor slab and the verticality of the wall panel.
[0053] Fifth, place the building sealing steel plate at the corner of the panel and fix it with mounting bolts. Then, spot weld the end steel plate joint to the outer steel plate of the panel to prevent the panel from warping.
[0054] Sixth, solid filler materials are used to fill the physical pores, further ensuring the sealing quality of the building.
[0055] The above description is merely an embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any variations or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present invention should be included within the protection scope of the present invention. Therefore, the protection scope of the present invention should be determined by the protection scope of the claims.
