Description

Technical Field

[0001] This utility model relates to the field of prefabricated building technology, and in particular to a light steel concrete wall that combines cold-formed thin-walled steel and corrugated steel plate. Background Technology

[0002] With the development of prefabricated steel structure buildings, the increasing demand for green construction and reducing the adverse environmental impact of the construction process has provided a favorable environment for the application of cold-formed thin-walled steel buildings in the Chinese market.

[0003] Cold-formed thin-walled steel structures, as a new type of green, low-carbon, energy-saving, environmentally friendly, and economical prefabricated steel structure, mainly consist of three parts: roof, floor, and walls. These components are connected by self-tapping screws. The cold-formed thin-walled steel walls are generally composed of C-shaped cold-formed thin-walled steel columns and U-shaped cold-formed thin-walled steel guide rails connected to form a frame, which is then covered with wall panels.

[0004] Traditional clad cold-formed thin-walled steel keel shear walls can no longer meet the requirements for seismic and shear resistance in building structures. As cold-formed thin-walled steel structures gradually develop from low-rise to multi-story / high-rise buildings, the increased self-weight and height of the structures lead to corresponding increases in seismic and wind loads. Therefore, the horizontal lateral forces of the structure need further improvement, requiring shear walls with better lateral force resistance.

[0005] In response to the challenges posed by earthquake-prone areas and the increasing demands of multi-story and high-rise building applications, the mechanical properties of traditional low-rise cold-formed thin-walled structures are facing difficulties, necessitating the development of new wall materials with superior performance to meet the needs of multi-story and high-rise buildings. Utility Model Content

[0006] To address the aforementioned shortcomings of existing technologies, the purpose of this utility model is to provide a lightweight steel-concrete wall that combines cold-formed thin-walled steel and corrugated steel plates, which can effectively improve the strength and stability of the wall, thereby enhancing its seismic and shear resistance, making it more suitable for use in earthquake-prone areas and multi-story / high-rise buildings.

The two plates of the L-shaped connector are respectively attached to the L-shaped steel beam and the C-shaped steel column and fixedly connected to the L-shaped steel beam and the C-shaped steel column by self-tapping screws.

[0012] Furthermore, an anti-pull-out member is provided at the upper and lower ends of the two double-limb C-shaped side columns on one or both sides of the outer frame of the wall. The anti-pull-out member is fixedly connected to the C-shaped steel column by self-tapping screws, and a rubber pad is provided between the anti-pull-out member and the C-shaped steel column.

[0014] Furthermore, the wall panel is made of magnesium crystal board.

[0015] Furthermore, pouring holes are provided on the upper double-limb L-shaped beam for pouring foamed concrete.

[0024] Example: See Figure 1 , Figure 2 as well as Figure 3 A lightweight steel-concrete composite wall combining cold-formed thin-walled steel and corrugated steel plates includes an outer frame comprising two double-limb C-shaped side columns 1 and two double-limb L-shaped beams 2. The two double-limb C-shaped side columns 1 are formed by connecting two C-shaped steel columns back-to-back, and the two double-limb L-shaped beams 2 are formed by connecting two L-shaped steel beams together with a single plate. As an optimization, both C-shaped steel columns of the double-limb C-shaped side columns 1 and both L-shaped steel beams of the double-limb L-shaped beams 2 are made of cold-formed thin-walled steel, thus significantly improving the strength and stability of the entire outer frame. During assembly, both ends of the double-limb L-shaped beams 2 are connected to the double-limb C-shaped side columns 1 via L-shaped connectors 7. The two plates of the L-shaped connectors 7 are respectively attached to the L-shaped steel beams and C-shaped steel columns and fixedly connected to them with self-tapping screws, thereby improving the connection stability of the two double-limb C-shaped side columns 1 and the two double-limb L-shaped beams 2.

[0025] A rectangular frame structure of a panel 3 is provided inside the outer frame of the wall. The two sides of the panel 3 extend into the space between the two C-shaped steel columns of the two double-limb C-shaped side columns 1 and are fixedly connected to the double-limb C-shaped side columns 1 by self-tapping screws. The two ends of the panel 3 extend into the space between the two L-shaped steel beams of the two double-limb L-shaped beams 2 and are fixedly connected to the double-limb L-shaped beams 2 by self-tapping screws.

[0026] Corrugated steel plates 4 are provided on one or both sides of the enclosure 3. The two sides of the corrugated steel plates 4 overlap with the two sides of the enclosure 3, and the two ends of the corrugated steel plates 4 overlap with the two ends of the enclosure 3. The overlapping portions of the corrugated steel plates 4 and the enclosure 3 are fixedly connected by self-tapping screws. Several through holes are provided on the web of the corrugated plates to facilitate the flow of lightweight foamed concrete 6 during pouring. In practice, pouring holes are provided on the upper double-limb L-shaped beam 2 for pouring the foamed concrete 6.

[0027] A wall panel 5 is provided on each side of the outer frame of the wall. The wall panel 5 is fixedly connected to two double-limb C-shaped side columns 1 and two double-limb L-shaped steel beams by self-tapping screws. Foamed concrete 6 is filled in the space enclosed by the two double-limb C-shaped side columns 1, the two double-limb L-shaped beams 2 and the two wall panels 5. As one embodiment, the wall panel 5 is made of magnesium crystal board.

[0028] An anti-pull-out member 8 is provided at the upper and lower ends of the two double-limb C-shaped side columns 1 on one or both sides of the outer frame of the wall. The anti-pull-out member 8 is fixedly connected to the C-shaped steel column by self-tapping screws, and a rubber pad 9 is provided between the anti-pull-out member 8 and the C-shaped steel column.

[0029] The improved production process of this solution enables rapid batch processing in the factory. Furthermore, the corrugated steel plate 4 possesses high strength, good ductility, high initial stiffness, and excellent out-of-plane stability, and exhibits good adhesion between the corrugated steel plate 4 and the lightweight foamed concrete 6. Combined with the edge columns and beams supported by cold-formed thin-walled steel profiles, and then filled internally with lightweight foamed concrete 6, a composite wall is formed. This effectively reduces the overall weight of the wall while improving its overall strength and stability, thereby significantly enhancing its seismic and shear resistance. This contributes to promoting the development of cold-formed thin-walled steel structures towards multi-story and high-rise buildings.
