Abstract
The invention discloses a continuous reinforcing method for existing simple-supported C-shaped purlines, which is characterized in that thin-wall L-shaped steel is embedded into the end parts of two adjacent simple-supported C-shaped purlines to connect the two adjacent simple-supported C-shaped purlines to form the continuous purlines, the simple-supported C-shaped purlines and the embedded thin-wall L-shaped steel are connected through purline supports at the positions of supports through bolts, and the simple-supported C-shaped purlines and the embedded thin-wall L-shaped steel are connected in a lap joint mode through self-tapping screws or in a glue joint mode.
Description
Technical field
The present invention relates to a kind of structural strengthening of construction steel structure field of engineering technology, specifically a kind of existing freely-supported c-type
Purlin reinforcement means.
Background technology
Cold bending thin wall purlin is divided into freely-supported purlin and continuous purline according to connecting node form.Freely-supported c-type purlin extensively should
For roofing system with lightweight steel structure and metope.During house use, due to load increase, or using factors such as function changes, cause
Freely-supported purlin Lack of support to freely-supported purlin, it is necessary to reinforce, and generally use changes purlin component or increase purlin is reduced
The methods of purlin spacing, but trouble of constructing, efficiency is low, and cost is high.
The content of the invention
To solve the problems such as existing freely-supported c-type purlin strengthening member method is time-consuming, cost is high, is not easy to construct, the present invention carries
Go out a kind of existing freely-supported c-type purlin serialization reinforcement means, the reinforcement means simple structure, easy to process, cost is low, Neng Gouxian
Write the bearing capacity for improving existing freely-supported c-type purlin.
In order to achieve the above object, the technical solution adopted by the present invention is that thin-walled L-type is embedded between adjacent freely-supported c-type purlin
Steel.Embedded thin-walled L-type steel size should match with freely-supported c-type purlin size.A kind of scheme is embedded thin-walled L-type steel and c-type purlin
Strip adoption self-drilling connection, including adjacent existing freely-supported c-type purlin, embedded thin-walled L-type steel, tapping screw.Embedded thin-walled L-type
Steel drills in advance at middle part and freely-supported c-type purlin end bolt hole correspondence position, is then inserted in adjacent freely-supported c-type purlin end
Thin-walled L-type steel, thin-walled L-type steel is embedded at bearing with purlin support, c-type purlin bolt connection, embeds thin-walled L-type steel and freely-supported c-type
Purlin web uses self-drilling connection on the upper and lower edge of a wing simultaneously；Another scheme is embedded thin-walled L-type steel and freely-supported c-type
Structure gemel connection, including adjacent existing freely-supported c-type purlin, embedded thin-walled L-type steel, bonding layer are used between purlin.Embedded thin-walled L-type
Steel drills in advance at middle part and freely-supported c-type purlin end bolt hole correspondence position, then in freely-supported c-type purlin and embedded thin-walled L
Brushing structure glue in the range of shaped steel nested lengths, thin-walled L-type steel is inserted in adjacent freely-supported c-type purlin end, embeds thin-walled L-type steel
Be connected with adjacent freely-supported purline gumming, at bearing with purlin support bolt connection.
The invention has the advantages that by embedding thin-walled L-type steel to existing freely-supported c-type purlin, using tapping screw or
It is glued connection and makes continuous purline, so as to significantly improve the bearing capacity of c-type purlin, its reinforcement means simple structure, into
This is relatively low.
