Definitions

  • the present invention relates to a lightweight steel framing, and more particularly, to a three-dimensional lightweight steel framing.
  • a lightweight steel structure with a lightweight steel framing has been developed rapidly and widely used in industrial buildings. Despite of high manufacturing cost of the lightweight steel structure, the lightweight steel structure still has advantages of short construction period, low energy consumption and low carbon emission, which make the lightweight steel structure more competitive than traditional concrete structure in the market. Therefore, the lightweight steel structure becomes more and more popular in low-rise residential buildings.
  • a structural beam and a structural column of the lightweight steel structure are usually connected with each other in a butt joint (e.g., in a fixed or hinged manner). Such connection complicates an assembly process of the lightweight steel structure and results in a serious accumulative error during assembly.
  • a column or a brace is usually secured onto an anchor bolt.
  • the anchor blot is positioned and embedded on site, which complicates the assembling process.
  • China Patent Application No. 200920158989.3 filed on Jun. 30, 2009 it provides an integral positioning steel frame to overcome the aforementioned drawbacks.
  • a fastener for securing the anchor blot cannot maintain an upright posture and is easy to be loose because the fastener is fixed onto only one point on a bottom of the integral positioning steel frame.
  • a hollow structural section is usually formed by an enclosed square-shape steel tube or two C-shaped steel members welded to each other.
  • a connection hole on the enclosed square-shape steel tube is formed by drilling or flame cutting instead of punching, which increases manufacturing cost.
  • a high strength fastener cannot be used for connecting the enclosed square-shape steel tube, which reduces connection strength.
  • the enclosed square-shape steel tube is required to be galvanized after machining, which also increases manufacturing cost. If two galvanized C-shaped steel members are welded to each other, a galvanized coating layer may be damaged.
  • China Patent Application No. 201010216616.4 filed on Jun. 30, 2010, it overcomes the aforementioned drawbacks.
  • a compressive strength of a square-shaped steel tube filled with concrete/cement mortar is far greater than a bearing capability calculated by a slenderness ratio of the square-shaped steel tube.
  • the concrete/the cement mortar has no function.
  • the square-shaped steel tube with the concrete/the cement mortar cannot be arranged closely during transportation, which results in excessive transportation volume and high transportation cost.
  • a positioning and supporting member cannot position a steel mesh and a wall body firmly, which allows a painted layer to be easily cracked along a longitudinal direction of the positioning and supporting member.
  • a main object of the present invention is to provide a three-dimensional lightweight steel framing with enhanced structural strength, so that a heavy material, such as a brick, concrete, or soil, can be adapted for the three-dimensional lightweight steel framing.
  • Another object of the present invention is to provide a three-dimensional lightweight steel framing with simple structure which meets the safety and environmental standards and facilitates the in-situ operation.
  • a three-dimensional lightweight steel framing includes a beam, a purlin and/or a stringer, a column, a wall body, a floor slab and/or a roof, and a lateral-force-resistant rod and/or tension braces.
  • the beam is a continuous double beam including two identical or different continuous single beams attached at both sides of the column.
  • the continuous single beam and the column are continuous and not interrupted at a cross joint of the continuous single beam and the column. As a result, it reduces accumulative errors during the connection of the beams and simplifies a connecting process of the columns and the beams.

Description

    BACKGROUND OF THE INVENTION
  • 1. Field of the Invention
  • The present invention relates to a lightweight steel framing, and more particularly, to a three-dimensional lightweight steel framing.
  • 2. Description of the Prior Art
  • A lightweight steel structure with a lightweight steel framing has been developed rapidly and widely used in industrial buildings. Despite of high manufacturing cost of the lightweight steel structure, the lightweight steel structure still has advantages of short construction period, low energy consumption and low carbon emission, which make the lightweight steel structure more competitive than traditional concrete structure in the market. Therefore, the lightweight steel structure becomes more and more popular in low-rise residential buildings.
  • However, there are still some drawbacks to be improved. For example, a structural beam and a structural column of the lightweight steel structure are usually connected with each other in a butt joint (e.g., in a fixed or hinged manner). Such connection complicates an assembly process of the lightweight steel structure and results in a serious accumulative error during assembly.
  • In China Patent Application No. 200920171128.9 filed on Aug. 20, 2009, it provides a lightweight steel framing without a floor slab, a roof, a reinforced lightweight composite floor slab, and a lateral-force-resistant rod. Therefore, an overall structural strength of the lightweight steel framing is insufficient. Furthermore, a cross section of a continuous double beam of the lightweight steel framing cannot be changed according to different situation, which is not flexible and wastes material. Moreover, the continuous double beams are connected to each other by a crisscross joint. Such connection results in extra space consumption and ununiformed load distribution. Furthermore, it is difficult to connect the long continuous double beams with such connection.
  • A column or a brace is usually secured onto an anchor bolt. The anchor blot is positioned and embedded on site, which complicates the assembling process. In China Patent Application No. 200920158989.3 filed on Jun. 30, 2009, it provides an integral positioning steel frame to overcome the aforementioned drawbacks. However, a fastener for securing the anchor blot cannot maintain an upright posture and is easy to be loose because the fastener is fixed onto only one point on a bottom of the integral positioning steel frame. Furthermore, it takes much time to cure concrete before securing the anchor bolt and assembling the lightweight steel framing, which extends construction period.
  • A hollow structural section (HSS) is usually formed by an enclosed square-shape steel tube or two C-shaped steel members welded to each other. In practical applications, a connection hole on the enclosed square-shape steel tube is formed by drilling or flame cutting instead of punching, which increases manufacturing cost. Furthermore, a high strength fastener cannot be used for connecting the enclosed square-shape steel tube, which reduces connection strength. Moreover, in order to prevent rusting, the enclosed square-shape steel tube is required to be galvanized after machining, which also increases manufacturing cost. If two galvanized C-shaped steel members are welded to each other, a galvanized coating layer may be damaged. In China Patent Application No. 201010216616.4 filed on Jun. 30, 2010, it overcomes the aforementioned drawbacks. However, a compressive strength of a square-shaped steel tube filled with concrete/cement mortar is far greater than a bearing capability calculated by a slenderness ratio of the square-shaped steel tube. In other words, the concrete/the cement mortar has no function. Furthermore, the square-shaped steel tube with the concrete/the cement mortar cannot be arranged closely during transportation, which results in excessive transportation volume and high transportation cost.
  • In China Patent Application No. 201310044986.8 filed on Feb. 4, 2013, in order to reduce a weight of a floor slab and improve performance of waterproof and fireproof of the floor slab, it reduces a thickness of the floor slab for reducing the weight of the floor slab. However, a lateral force resistance of the floor slab is reduced at the same time, which reduces a capability of the floor slab for transferring a horizontal force.
  • In China Patent Application No. 200920147815.7 filed on Apr. 14, 2009, and China Patent Application No. 201310664792.8 filed on Dec. 10, 2013, an expanded ribbed mesh cannot be engaged with the web firmly, so that a stressed-skin effect is reduced.
  • In China Patent Application No. 201110023291.2 filed on Jan. 20, 2011, a positioning and supporting member cannot position a steel mesh and a wall body firmly, which allows a painted layer to be easily cracked along a longitudinal direction of the positioning and supporting member.
  • Therefore, there is a need to design a three-dimensional lightweight steel framing to overcome the above drawbacks.
    • SUMMARY OF THE INVENTION
  • A main object of the present invention is to provide a three-dimensional lightweight steel framing with enhanced structural strength, so that a heavy material, such as a brick, concrete, or soil, can be adapted for the three-dimensional lightweight steel framing.

The steel member is preferably formed by cutting or cold rolling a galvanized steel reel, which facilitates automated production. During the production and the in-situ assembly, no welding process is required, so it prevents a galvanized layer from being damaged. The reinforced strength of the three-dimensional lightweight steel framing makes a traditional slurry-type wall body made of heavy materials, such as bricks, concretes and soils, and the recycled materials, be used cooperatively. Furthermore, by disposing two continuous single beams on both sides of the column, it reduces accumulative error during assembly.
