Description
Technical field
The utility model relates to building engineering field, particularly a kind of large span portal-rigid frames post, beam connecting node.
Background technology
At present; in engineering construction; usually can run into large span portal-rigid frames post; the beam connectivity problem; and adopt several high-strength bolts to connect at the web place in the conventional way; because high-strength bolt installation accuracy height; especially strict especially to the deviation of bolt hole; even if but in fabrication and installation rigid-framed structure process, carry out fabrication and installation in strict accordance with job specfication; accumulated error at the rigid-frame column top seldom can satisfy the required precision that high-strength bolt is installed; even if take rational correction; effect is still not obvious; in practice of construction, need usually some treatment measures are taked in the high-strength bolt hole; the ability normal mounting, but do not meet the code requirement that high-strength bolt is installed, can not reach high-strength bolt connected node force request; thereby influence the stressed of total; correction work is installed has simultaneously also expended great amount of manpower and material resources, installation period is also longer, directly has influence on the installation progress of structure.People, machine fall and imitate seriously in the work progress.
Summary of the invention
The utility model for solve the technical problem that exists in the known technology provide a kind of connect reliable, can the rapid and convenient construction and satisfy rigid-frame column, the beam connecting node of stressed and appearance requirement.
The technical scheme that the utility model is taked for the technical problem that exists in the solution known technology is: a kind of large span portal-rigid frames post, beam connecting node, the top of described rigid-frame column is provided with the perpendicular H type column cap that extends to described rigit-frame beam, described rigit-frame beam is the H section steel beam, web one side of described H type column cap is connected with the first web clamping plate, the web opposite side of described H section steel beam is connected with the second web clamping plate, described first web clamping plate and the described second web clamping plate are affixed by bolt, and the described first web clamping plate are connected by the fillet weld seam with the web of described H type column cap and the web of described H section steel beam with the described second web clamping plate; The frange plate up and down of described H type column cap is connected by the butt weld that adds liner plate with the frange plate up and down of described H section steel beam.
Described butt weld is a groove weld.
Described butt weld is a V-weld.
Advantage and the good effect that the utlity model has are: adopt the top frange plate that liner plate is set and realize the welding of groove complete penetraction and fusion in welding, middle pectoral plate is provided with two-sided clamping plate and adopts the fillet weld seam welding with it, and some erection bolts location is set at the web place, realized being rigidly connected in the full section, rigid-frame column reliably is connected with beam; The apparent size requirement of structural system after guaranteeing to be shaped, good mechanical performance; Constructing operation is convenient, improves people, machine efficiency of construction greatly.
