Description
Technical field
The utility model relates to a kind of fixed mechanism of strengthening the bending resistance square shearing resistance of light steel roof truss central sill and beam, beam and column node, and this fixed mechanism has strengthened compressive resistance and the stretching resistance performance of beam at the node place simultaneously.
Background technology
The structure of light steel roof truss and the structure practice have very big influence to quality and the construction of light steel building.The main support member of light steel roof truss, as structural beams and structural column, generally the steel sheet by thickness 1.0-5mm is constituted through light-gauge steel section and the goods thereof of clod wash or cold rolling moulding.The light gauge cold-formed steel shape section bar also comprises the die mould steel sheet of the following various types of thickness 1.0mm, and its goods often have the function that supports and go along with sb. to guard him two aspects.In addition, the member that adopts small bore shaped steel such as angle steel, Guan Gang, channel-section steel, band steel and round steel etc. to form, or with the member that light gauge cold-formed steel shape is formed, also be commonly used for the supporting member of lightweight steel construction, as purlin connector, batter brace etc.
But, use the light steel of light steel roof truss to build, no matter in architectural design, structure design, still at the fabrication and installation technical elements, also have very big improvements.When the light steel roof truss that uses is assembled at the scene at present, supporting member wherein, as the structural beams made by light gauge cold-formed steel shape, angle steel, channel-section steel or steel plate, structural column, purlin etc., generally adopt docking mode (as secure bond or hinged) to connect, locate or fixing.Because quantity such as the structural beams in the light steel roof truss of present this structure, structural column, purlin are huge, this docking mode causes the combined process complexity, produces the serious accumulation of error simultaneously.
In order to overcome above-mentioned defective, it is 200920171128.9 utility model patent that the design people has submitted to name to be called " the light steel roof truss that is provided with continuous twin-spar construction ", the patent No. on August 20th, 2009.The full content of this patent is introduced in the utility model as a whole.
In this patent, the design people has proposed the technical scheme of " twin beams continuously ".In the prior art, beam disconnects being combined fixing place with post.The defective of doing so namely " causes the combined process complexity, produces the serious accumulation of error simultaneously " as mentioned above.Adopt continuous twin beams, beam and column does not disconnect in conjunction with bearing's beam, and beam is continuous, thereby has overcome above-mentioned defective.
Adopted continuous twin beams, at the crossover node of Liang Yuzhu, twin beams applying pillar both sides are passed through continuously.Liang Yuzhu fixes by the mechanical engagement mode in its contact surface scope.But the contact area of beam and column is less, and bolt or rivet usage quantity are limited, and material thickness is thinner, can't form effective bending resistance square and shear-stable ability.The contact surface of light gauge cold-formed steel shape structure twin beams and post crossover node is fixed in the mechanical engagement mode, and the mechanical engagement mode comprises as bolt, rivet and brill tailfiber etc.But owing to limited by contact area, bolt or rivet are can not quantity too much, node bending resistance square performance and shearing resistance performance, and beam the compressive resistance at node place and stretching resistance performance a little less than.
Therefore, the fixed form of prior art center pillar and beam and structure produce a lot of defectives when reality is used.
Because above-mentioned defective, the design people is based on being engaged in this type of product design manufacturing abundant practical experience and professional knowledge for many years, and cooperates the utilization of scientific principle, actively studied innovation, proposed a kind of novel post, the fixedly connected mode of beam and structure.
