Description

Technical Field

[0001] The invention belongs to the technical field of light steel buildings, in particular to an assembled light steel integrated house. Background Art

[0002] As people's demand for housing has greatly increased, their requirements for living conditions have become increasingly higher, leading to the rapid development of the construction industry.

[0003] As the name suggests, prefabricated buildings are buildings that prefabricate components in advance in a processing plant and connect them at the construction site through mechanical connections and other methods to assemble the individual components into a whole. Prefabricated buildings can greatly reduce construction time and overall construction costs, while also meeting the requirements of green development.

[0004] Lightweight steel prefabricated buildings are mainly made of lightweight steel keels made of hot-dip aluminum-zinc strip steel through cold rolling technology. After precise calculations and the support and combination of auxiliary parts, they have a reasonable bearing capacity to replace traditional houses. In addition, the high efficiency brought by industrialized production shortens the construction period by 2 / 3 compared with traditional buildings. Its excellent performance determines its super high cost-effectiveness in comprehensive comparison. All its materials can be fully produced in factories and assembled and installed at the construction site, which not only reduces the intensity of on-site construction, but also improves construction efficiency and project quality.

[0005] The aluminum-zinc alloy structure of the aluminum-zinc steel plate in the light steel prefabricated building is composed of 55% aluminum, 43.4% zinc and 1.6% silicon solidified at a high temperature of 600°C. The entire structure is composed of aluminum-iron-silicon-zinc, forming a dense quaternary crystal, thus forming a strong barrier that effectively prevents corrosion factors from penetrating. The light steel keel has good corrosion resistance, heat resistance, high reflectivity and good paintability, and is widely used.

[0006] In traditional light steel prefabricated buildings, light steel keels and light steel keels to columns are usually connected and fixed by welding or simply bolting. During assembly, due to the effects of various stresses, light steel keels are prone to bending, resulting in lower quality of assembled houses and even safety hazards. Summary of the invention

[0007] In order to solve the above problems, the present invention provides an assembled light steel integrated house, which reinforces the entire wallboard frame, ensures the accuracy of the installation of the horizontal keel and the longitudinal keel, avoids the bending of the keel, ensures that the assembled house has high quality, and avoids safety hazards. The overall structure is simple, the assembly is convenient and efficient, and the practicability is good.

[0008] The present invention is achieved through the following technical solutions:

[0009] An assembled light steel integrated house comprises columns, a wall panel frame connected to the columns and a top plate arranged above the wall panel frame, the wall panel frame comprises a plurality of keels with a U-shaped cross section which are cross-connected and installed horizontally and vertically, the keels comprise a transverse keel and a longitudinal keel, the webs of the transverse keel and the longitudinal keel are fitted and connected, a plurality of longitudinal connecting screws are penetrated on the wing plates of the transverse keel, a plurality of transverse connecting screws are penetrated on the wing plates of the longitudinal keel, and a fastening nut which abuts against the outer side of the wing plates of the keel is screwed on the connecting screw.

[0010] A further improvement of the present invention is that the column is a square steel structure, and the end of the transverse connecting screw rod passes through the side wall of the column and is screwed and installed through a tightening nut.

[0011] A further improvement of the present invention also includes a frame connected and installed at the upper and lower ends of the wall panel frame; the frame is welded from square steel, and the ends of the longitudinal connecting screws pass through the side walls of the frame and are screwed and installed through a tightening nut.

[0012] A further improvement of the present invention is that the inner side supports of the two wing plates of the keel are provided with support sleeves which are fitted with the connecting screws.

[0013] A further improvement of the present invention is that the longitudinal connecting screws are arranged alternately with the longitudinal keels, and the transverse connecting screws are arranged alternately with the transverse keels.

[0014] A further improvement of the present invention is that the edge of the wing plate of the keel is folded inward to form a folding plate, and the folding plate is provided with a mounting hole for positioning and mounting the wall panel.

[0015] A further improvement of the present invention is that the web of the transverse keel and the web of the longitudinal keel are installed by fitting and welding.

[0016] A further improvement of the present invention is that the web of the transverse keel and the web of the longitudinal keel are penetrated and positioned by mounting bolts, and mounting nuts are screwed onto the mounting bolts.

[0017] A further improvement of the present invention is that four diagonally arranged mounting bolts are provided at the joint connection positions of a transverse keel and a longitudinal keel.

[0018] It can be seen from the above technical solutions that the beneficial effects of the present invention are:

[0019] The connecting screws are arranged longitudinally between the transverse keels and are connected to the outer side of the wing plate of the transverse keel through the fastening nuts. The connecting screws are arranged transversely between the longitudinal keels and are connected to the outer side of the wing plate of the longitudinal keel through the fastening nuts, so as to strengthen the entire wallboard skeleton, ensure the accuracy of the installation of the transverse keel and the longitudinal keel, avoid the bending of the keel, ensure the high quality of the assembled house, and avoid safety hazards.
