Abstract
The utility model relates to an include C shape purlin and locate the reinforcement steel sheet at C shape purlin middle part, the width of reinforcing the steel sheet with the width of C shape purlin is the same, it establishes to consolidate the steel sheet lid opening one side of C shape purlin, along two rows of self-tapping nails that transverse direction distributes will consolidate the steel sheet with the folded plate of the inside bending of pterygoid lamina of C shape purlin is together fixed, every row of self-tapping nail includes a plurality of self-tapping nails of indulging the range of a plurality of edges, the middle part of consolidating the steel sheet is equipped with the perforation that supplies the brace to pass, perforate with last lacing wire hole of C shape purlin is just to setting up. The utility model has the advantages that: simply prop up C shape purlin reinforced structure for when the installation need not to dismantle under load state, directly will consolidate the steel sheet and install C shape purlin middle part through the tapping screw can, just the reinforcement is striden and the structural strength of brace department, and is with low costs, efficient.
Description
Technical Field
The utility model relates to a building steel structure engineering consolidates technical field, mainly is simply supported C shape purlin reinforced structure.
Background
In recent years, the use of new energy is vigorously advocated in the country, and many old light steel structure industry factory buildings need upgrading transformation, need increase solar cell panel and photovoltaic support newly on former roof boarding, have increased roofing design load, cause the design bearing capacity of former roofing simple supported C type purlin to satisfy the demand, hide huge potential safety hazard.
The traditional purlin reinforcing method comprises the following steps: the purlin that will have the potential safety hazard is dismantled later to change the great purlin of cross sectional dimension or will simply prop up the purlin and locate the overlap joint at the support and form continuous purlin or increase the purlin and reduce the purlin interval etc. but above method dismantles under load condition inconveniently, and is with high costs, and is efficient, and in addition, C type cross section purlin is unlike Z type cross section purlin, because the cross-section equals, can not realize mutual nested overlap joint well in support department, and original purlin also not all parts can not be used, only there is weak point, generally stride well or brace department.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a simply supported C shape purlin reinforced structure.
In order to solve the technical problem, the technical scheme of the utility model as follows:
a simple C-shaped purlin reinforcing structure comprises C-shaped purlins and reinforcing steel plates arranged at the middle parts of the C-shaped purlins, wherein the reinforcing steel plates are as wide as the C-shaped purlins, reinforcing steel plate covers are arranged on one sides of openings of the C-shaped purlins, two rows of self-tapping nails distributed along the transverse direction are used for fixing the reinforcing steel plates and folded plates of wing plates of the C-shaped purlins, which are bent inwards, each row of self-tapping nails comprise a plurality of self-tapping nails arranged longitudinally, the middle parts of the reinforcing steel plates are provided with through holes for pulling strips to penetrate through, and the through holes are arranged right opposite to pull strip holes in the C-shaped purlins.
Preferably, each row of self-tapping screws comprises an end self-tapping screw group and a middle self-tapping screw group, and the distance between adjacent self-tapping screws in the end self-tapping screw group is smaller than the distance between adjacent self-tapping screws in the middle screw group.
The utility model has the advantages that: simply prop up C shape purlin reinforced structure for when the installation need not to dismantle under load state, directly will consolidate the steel sheet and install C shape purlin middle part through the tapping screw can, just the reinforcement is striden and the structural strength of brace department, and is with low costs, efficient.
Furthermore, the self-tapping screws of the end self-tapping screw group are spaced smaller and denser, and the purpose is to enhance the firmness of end fixing and prevent the end from loosening and even disengaging due to factors such as stress.
