Technical field
The present invention relates to steel building technical field of construction, it particularly relates to a kind of separate type precast truss frame building holds
Plate and its construction method.
Background technology
With social development, in modern architecture, steel building gets more and more, the purlin using cooperatively with girder steel, steel reinforced concrete group
Frame floor support plate is because it substantially reduces live reinforcing bar binding engineering amount, accelerating construction progress, increases construction safety guarantee, realizes literary composition
The advantages of bright construction, assembled template and connector easy accessibility, increasingly it is subject to the pro-gaze of construction enterprises.
At present, existing truss floor support plate bottom is profiled sheet, and lower edge reinforcing bar and web member are directly welded at die mould steel
On plate, but because in order to control cost to mitigate the overall weight of truss floor support plate simultaneously, current floor support plate bottom is typically adopted
With the zinc-plated profiled sheet that 0.5mm is thick, because profiled sheet is relatively thin, it is very easy to during welding procedure damage zinc coat, or even will
Profiled sheet directly penetrates, and so that reinforcing bar is caused corrosion, connect not firm, formation hidden danger of quality；Meanwhile, described profiled sheet is treated
Just no use after being poured, but but cannot remove it is clear that to also result in waste of material serious.
So, develop a kind of precast truss frame floor support plate that ensure that quality safety and be beneficial to environmental protection and saving, become
Problem for insider's urgent need to resolve.
Content of the invention
For the above-mentioned technical problem in correlation technique, the present invention proposes a kind of separate type precast truss frame floor support plate, can
Ensure quality safety, and be also beneficial to environmental protection and saving.
For realizing above-mentioned technical purpose, the technical scheme is that and be achieved in that：
A kind of separate type precast truss frame floor support plate, including junction steel plate and be arranged on described junction steel plate lower end with described
The profiled sheet of junction steel plate cooperation, described profiled sheet is threadeded by connecting bolt with described junction steel plate；Described company
Connecting bolt upper end is connected with lower edge reinforcing bar, and described lower edge reinforcing bar is winded up reinforcing bar by web member bar connecting；And, described web member
Reinforcing bar is provided with upright rib double-fold.
Further, the described reinforcing bar and lower edge reinforcing bar corresponding position with described web member reinforcing bar respectively by way of welding of winding up
Put connection.
Further, described connecting bolt by welding by way of with described lower edge bar connecting.
Further, described junction steel plate thickness is identical with thickness of concrete cover.
A kind of construction method of separate type precast truss frame floor support plate, its step includes：
1）By winding up, reinforcing bar is respectively welded on the correspondence position of web member reinforcing bar with lower edge reinforcing bar.
2）Connecting bolt is welded on lower edge reinforcing bar correspondence position.
3）Connecting bolt passes through junction steel plate and profiled sheet, by screwing junction steel plate with fixing nut.With die mould
Interal fixation connects, and it is ensured that junction steel plate is vertical with every piece of truss plate plate length direction.
4）In-site installation building holds truss plate, and, colligation floor support plate level is to cage bar.
5）Carry out floor concrete casting operation.
6）To be cast complete, twist and go fixing nut, remove bottom profiled sheet.
Beneficial effects of the present invention：The present invention is threaded connection replacement welding manner, decreases what welding procedure brought
Hidden danger of quality is it is ensured that working security, and so that profiled sheet can be reused, and is conducive to environmental protection and saving, reduces system
Cause this, bring great economic benefit.
