Three-dimensional light steel frame composed of two-way continuous double beams

PRIORITY CLAIM OF THE INVENTION The present application claims priority to U.S. Patent No. 201410035766.3, entitled "S. s. in.

The invention relates to the field of light steel construction, in particular to a three-dimensional light steel frame composed of a bidirectional continuous double beam for light steel construction.

Light steel buildings using light steel roof trusses have entered a period of rapid development in China and have been widely used in industrial buildings. Light steel houses have become a new field and a new growth point for light steel structure applications. At present, the cost of light steel construction is generally higher than that of traditional concrete structures, but it has competitive advantages such as fast construction, energy saving and emission reduction. More and more construction units have recognized the superiority of light steel structures and have gradually become the preferred structural form for industrial buildings, and have also been widely used in low-rise civil buildings.

Light steel construction using light steel roof trusses has significant improvements in terms of architectural design, structural design, and fabrication and installation techniques. Currently used light steel roof truss structural beams, structural columns, etc. are generally connected by means of docking (such as fixed or hinged). Since a large number of structural beams, structural columns, and the like are used in the light steel roof truss of the present structure, the jointing method causes a complicated joining process and at the same time, a serious error accumulation occurs. The inventor filed on August 20, 2009, the patent number is 200920171128.9, and the utility model patent entitled "Light steel roof truss with continuous double beam structure". However, the patent still has the following deficiencies: the patent does not cover the floor, roof, and strong Lightweight composite floor slabs, anti-lateral force rods and other components cannot form a complete three-dimensional light steel structure. The continuous double beams do not define the relationship between two-way continuous double beams, and the three-dimensional frame assembly is difficult, individual components and the overall structure. Insufficient structural strength. In addition, the continuous double beam in this patent cannot meet the requirements of different sections according to different stress conditions, resulting in waste of material use. The continuous double beam can not adopt different single beam combination lacking flexibility according to different requirements; the roof truss and The connection between the trusses adopts a continuous double-beam overlapping combination, and the continuous double-beam connecting members are too long to cause difficulty in assembling the frame, and the two-way continuous double-beam overlapping combination causes space waste, and causes uneven stress on the column and beam joints. .

The use of distributed components to assemble light steel (such as cold-formed thin-walled steel) on site is to fix individual steel frame columns or steel frame braces to the pre-embedded anchor bolts. The number of steel frame columns and braces Large, the position of the embedded anchor bolt fixing parts needs to be measured and positioned on site, so the pre-buried process is very complicated, and the accuracy of the position of these pre-embedded anchor bolt fixing joints is difficult to grasp, and the positioning is actually constructed. The process is quite time consuming and laborious. The inventor's patent number ZL200920158989.3, entitled "Integrated Positioning Steel Frame for Light Steel Construction", which was submitted on June 30, 2009, solves the above problems, but has the following disadvantages: The embedded bolt fixing connector is only fixed at one point of the bottom of the integrated positioning steel frame member, can not maintain vertical, and is easily loosened during construction. At the same time, the embedded bolt must be assembled and locked after the foundation concrete reaches a certain strength. Steel frame.

Square steel parts commonly used in the field of light steel construction are generally square steel tubes or butt welded with two C-shaped steels. The bolt holes of the closed square steel pipe connected with other components can only be processed by drilling or flame cutting, and cannot be punched by punching, which leads to high processing cost; the closed square steel pipe cannot be joined with other components by using the locking high-tension bolt. Thereby greatly reducing the bearing capacity of the joint. In order to prevent rust, galvanization is generally performed after the processing of the square steel pipe is completed, which results in high production cost. For example, C-beam butt welding with two galvanized steel sheets is formed by roll forming. The work method will destroy the rust-proof layer of the galvanized steel sheet. The invention patent of the patent no. 201010216616.4 entitled "Square Light Steel Member with Reinforcing Parts" was filed by the inventor on June 30, 2010. The above problem is solved, but the following technical deficiencies still exist: When the inner cavity of the square steel pipe is filled with concrete or cement mortar, the compressive strength of the cross section of the column is far greater than the overall pressure bearing capacity of the column determined by the slenderness ratio of the square steel pipe column, that is, The reinforcing member does not function because the concrete or cement mortar does not reach the pressure resistance, so the reinforcing member is not necessary, and the square light steel member provided with the reinforcing member cannot be buckled during transportation, which wastes transportation space. And transportation costs.

In order to reduce the weight of the floor and to enhance the waterproofness and fire prevention of the floor, the inventor's application number entitled "Light Composite Floor" submitted by the inventor on February 4, 2013 solves the above problem, but the technical solution of the patent In actual use, there are also the following defects: the "light composite floor slab" described in the patent mainly reduces the thickness of the slab and reduces the weight of the slab, but reduces the thickness of the slab so that the slab is frustrated when subjected to lateral pressure, thereby reducing the slab at three Dimensions The ability of a complete architectural structure to deliver horizontal forces.

In the light steel structure, the wall keel and the wall are properly strengthened and combined to achieve the skin effect. The patent number submitted by the inventor on April 14, 2009 is ZL 2009 2 0147815.7. The invention patent of the wall with the skin effect structure, the patent number 201310664792.8 filed on December 10, 2013, and the name "wall with skin effect" can solve the above problems, but the following also exist Weakness: In the above technical solution, the partition material layer causes the reinforced mesh to be unable to be well joined with the keel, resulting in a one-sided skin effect loss.

In order to achieve safety, energy saving, environmental protection and cost saving, the inventor's patent number ZL201110023291.2 submitted on January 20, 2011 is the invention of "wall with a spliced steel mesh structure". Patents can solve the above problems, but there are also the following weaknesses: The position support member is not stable enough to position the steel mesh and the wall body, and at the same time, it is easy to cause the paint layer to be longitudinally positioned to support the member crack.

In view of the shortcomings of the above-mentioned existing light steel structure, the inventor has actively researched and innovated based on the practical experience and professional knowledge of designing and manufacturing such products for many years, and with the use of academic principles, in order to create a new structure light steel structure. It is possible to improve the existing existing wall to make it more practical. After continuous research, design, and repeated trials of samples and improvements, the invention has finally been created with practical value.

The main object of the present invention is to overcome the defects of the existing light steel building, in particular, the existing housing system of the existing three-dimensional structure of the light steel building in the structure and construction, the investment in the production equipment, the wall and the interior equipment are too complicated. Moreover, it requires a professional construction team to start to work, and the cost is generally higher than that of the traditional brick-concrete structure, which leads to the difficulty in promoting the light industrialized wall building materials in many industrialized and underdeveloped areas, and proposes a new type of two-way continuous The three-dimensional light steel frame composed of double beams is designed to strengthen the structural strength of the light steel frame, so that traditional wet wall structures such as masonry blocks, concrete, soil and other heavy building materials can be used together, steel component production and on-site construction process Simplify and reduce capital investment while allowing non-building professionals to participate in the construction.
