Abstract

A three-dimensional light steel frame constituted by continuous and discontinuous dual side beams. The beams in the three-dimensional light steel frame are formed by combining one or more continuous and discontinuous single-sided beams (1) that are identical or different in terms of shape and structure. Such combination allows flexible and varied installations of light steel components and facilitates use. In addition, the employment of bolts (4) for fastening and fixing allows onsite installation to be simplified and a person unskilled in the construction profession to participate in a construction. The employment of a construction method in which a column is sandwiched by dual-sided beams allows the components to be assembled in parallel, favors the replacement and flexible transfer of the components, and also facilitates onsite assembly.

Description

 Three-dimensional light steel frame with continuous and discontinuous double-sided beams

Technical field

 The invention belongs to the technical field of light steel construction, in particular, relates to a three-dimensional light steel frame composed of continuous and discontinuous double side beams.

Background technique

 Light steel buildings using light steel roof trusses have entered a period of rapid development in China and have been widely used in industrial construction. Light steel housing has become a new field and new growth point for light steel structure applications. At present, the cost of light steel buildings 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 gradually become the preferred structural form for industrial buildings. They have also been widely used in low-rise civil buildings.

In light steel buildings using light steel roof trusses, there is still a lot of improvement in terms of architectural design, structural design, and production and installation technology. Currently used light steel roof truss structural beams, structural columns, etc. are generally connected using a docking method (such as fixed or articulated). Because a large number of structural beams, structural columns, etc. are used in the light steel roof trusses of this structure at present, this docking method complicates the bonding process and generates serious error accumulation. The same applicant filed a patent No. 200920171128 on August 20, 2009. 9. A utility model patent entitled "Light Steel Roof Truss with Continuous Double Beam Structure". However, the patent still has the following shortcomings: the patent does not involve a three-dimensional light steel frame system composed of continuous and discontinuous double-side beams. At the same time, the assembly of the three-dimensional frame is difficult, and the structural force of individual components and the overall frame is insufficient. In addition, in the patent, the continuous double girder cannot use different cross-sections in response to different stress conditions, resulting in waste of material usage. The continuous double girder cannot use different single girder combinations in response to different needs and lacks flexibility; the roof truss and roof truss The continuous double-beam overlapping combination is used for the connection. The continuous double-beam connecting member is too long, which makes it difficult to assemble the frame. The two-way continuous double-beam overlap and combination causes waste of space, and at the same time, the column beam joints are unevenly stressed. In addition, the same applicant submitted a utility model patent with a patent number of 201520052886.4 and a name of "Three-dimensional light steel roof truss consisting of two-way continuous double beams" filed on October 21, 2015. However, the patent still has the following deficiencies: 1. The patent does not involve the three-dimensional light steel frame system composed of continuous and discontinuous double side beams described in this patent. 2. The patent is limited to those including purlins and / or stringers, floor slabs, roofing, and reinforced lightweight composite floor slabs. 3. This patent does not involve the connection of continuous and discontinuous single-sided beams described in this patent with the column or beam-column connector at the web. 4. The patent does not involve the use of a discontinuous single beam for the continuous double-sided beam described in this patent, which is selected from the group consisting of channel steel, square section steel, open square section steel, circular steel pipe, and truss beam. 5. The patent does not relate to a three-dimensional light steel frame system with continuous and discontinuous double measuring beams described in this patent, and further provided with reinforcing members, the reinforcing members are located on the double side beams. Concrete, and / or between the cavities of the columns, the concrete is further or partially poured, and the concrete is further provided with stirrups and steel rods for strengthening the concrete.

 Square steel parts commonly used in light steel construction are generally square steel pipes. 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 with a punch, resulting in high processing costs; closed square steel pipes cannot be locked with other high-tension bolts, Thus greatly reducing the bearing capacity of the joint. In order to prevent rust, galvanizing is generally performed after the processing of square steel pipes, which results in high production costs. If two C-shaped steels are formed by butt welding of two galvanized steel sheets, this processing method will destroy the anti-rust layer of the galvanized steel sheets. The invention patent filed by the same applicant on June 30, 2010 with the number of 201010216616.4 entitled "Square Light Steel Member with Reinforced Parts" solves the above problems, but still has the following deficiencies: The technical solution of this patent is actually applied When the internal cavity of the square steel pipe is filled with concrete or cement mortar, the compressive strength of the column section 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, Said concrete or cement mortar does not reach the compressive strength to destroy the reinforcing member and it does not work. Therefore, the reinforcing member is unnecessary, and the square light steel member provided with the reinforcing member cannot be fastened during transportation, wasting transportation space and transportation cost.

In view of the shortcomings of the existing light steel structure mentioned above, the inventor is actively researching and innovating based on years of rich practical experience and professional knowledge engaged in the design and manufacture of such products, in conjunction with the application of science, with a view to creating a new type of light steel structure.
