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's patent number submitted on August 20, 2009 is 200920171128. 9. 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 refer to the slab, roof, reinforced lightweight composite slab, anti-lateral force pull rod and other components, and cannot form a complete three-dimensional light steel structure, the continuous double beam is not clear The relationship to the continuous double beam, the three-dimensional frame assembly is difficult, and the individual components and the overall frame structure are insufficient. 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, which was submitted on June 30, 2009, is entitled "Integrated Positioning Steel Frame for Light Steel Construction". The above problems are solved, but the following disadvantages exist: 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 rolling, and this processing 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 in 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". The patent can solve the above problems, but it also has the following weaknesses: the positioning support member is not stable enough to locate the steel mesh and the wall body, and at the same time, the whitewashing layer is likely to be longitudinally positioned to support the cracking of the support member.

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.

Embedding; when one side of the wall is flush with one side of the column, the beam does not protrude from the wall, and the decoration is easy and does not cause water leakage. When the dry construction method is adopted, the cavity between the continuous double beams is blocked, and the fire smoke barrier is formed to facilitate fire prevention.

In a preferred embodiment, the reinforcing structure is further formed by an open square steel in the lower girders of the truss beam, the open square steel opening is upward (ie, facing other components connected thereto), and is cut and placed in the truss beam. The steel plate at the intersection of the column and the diagonal bracing is provided with a locking connection hole on the steel plate on both sides of the open square steel, and is bolted to the locking connection hole provided by the column and the diagonal bracing in the truss beam. This solution facilitates the pouring of concrete/or cement mortar between the cavities of the open square steel.

In an embodiment of the invention, the continuous single beam is provided with a locking connection hole at the beam web and a locking connection hole provided on each side of the column to be tightly connected by a bolt. Since the components of the three-dimensional light steel frame composed of the two-way continuous double beam are mostly cold-formed thin-walled steel, the bolts form a weak point on the load-bearing load of the steel plate around the connection hole. Preferably, the reinforcing structure is provided for the light steel structure, and the reinforcing structure is provided with a thickened steel plate for reinforcing around the beam or the column locking connection hole; the thickened steel plate dispersing the bolt to the nuclear load of the steel plate surrounding the connecting hole.

In an embodiment of the invention, the reinforcing structure is reinforced by superimposing members on the outer side of the double beam. Since most of the members are cold-formed thin-walled steel, the bolts form a weak point on the load-carrying load of the steel plate around the locking connection hole, especially in the stress-concentrating member portion, for example, a vertical anti-lateral force bracing surrounding relevant node. The solution of the invention is reinforced on the outer side of the double beam, and the stress of the original continuous double beam and the joint is shared. Moreover, the reinforcement of the superimposed member is only strengthened for the insufficient structural force of the whole beam, and the cross section of the entire beam is not required to be strengthened, which can save materials. Preferably, in the form of the double beam, the superposed member may be an L-shaped steel, a U-shaped steel, a C-shaped steel, a flat steel, a square steel and/or a square wood. In particular, the use of square wood to cut off the cold bridge. Cold bridges are a major disadvantage of light steel in cold areas because steel is a good heat transfer body that will pass heat or cold.

In an embodiment of the invention, the reinforcing structure is such that a thermally conductive insulating spacer is added between the double beam and the outer superposed member. When the superimposed member adopts the L-shaped steel, the U-shaped steel, the C-shaped steel, the flat steel and/or the square steel, a heat conductive insulating gasket is added between the double beam and the outer superposed member to block the cold bridge .

In an embodiment of the invention, the column includes a structural main column, a small column, a block and/or a reinforcing column disposed in the infill wall, and a spot welded steel wire mesh and/or a woven wire mesh at the periphery of the column and / or expansion of the wire mesh package, and cement mortar with the block wall to form a reinforcement structure. The reinforcing structure can combine the block wall with the three-dimensional light steel frame integral frame formed by the two-way continuous double beam, so that the overall frame structure can be strengthened.

In an embodiment of the invention, the reinforcing structure overcomes the defects existing in the prior art, for example, the embedded bolt fixing connector is only fixed at a point on the bottom of the integrally positioned steel frame member, and cannot maintain vertical, during construction. It is easy to be loosened by collision, and the embedded bolt must be assembled and locked to the steel frame after the foundation concrete reaches a certain strength. The reinforcing structure described in the embodiment is provided with a bolt reinforcing gasket in an integrated positioning steel frame provided with a pre-embedded bolt reinforcing gasket, and the bolt reinforcing gasket is disposed above the C-shaped steel embedded bolt hole The bolt reinforcing spacer is provided with a bolt positioning connecting hole for fixing the pre-embedded bolt; the pre-embedded bolt can maintain vertical, and the pre-embedded bolt is not easily loosened by collision during construction.
