Abstract
The invention belongs to the technical field of buildings and discloses a steel bar truss floor board with a hollow cavity. The steel bar truss floor board comprises a floor board body which comprises trusses and the hollow cavity. The trusses comprise web member steel bars. Upper chord steel bars are arranged between the web member steel bars and welded to the web member steel bars. Lower chord steel bars are arranged at one sides of the bottom of the web member steel bars and welded to the web member steel bars. The hollow cavity is formed in one sides of the web member steel bars. By means of the hollow cavity, the mechanical structure of the floor board is more reasonable, damping performance and sound insulating performance of the floor board are improved, the amount of poured concrete of the floor board can be saved by 30%, pouring time of the floor board can be saved, and unnecessary waste, caused by large space between every two trusses, of much poured floor board concrete is avoided; the hollow cavity can be formed in a rolled mode through a flow production line in a factory, and the construction quality of the floor board is improved.

Technical field
The present invention relates to a kind of steel bar girder floor plates, be specifically related to a kind of steel bar girder floor plates adding hollow cavity, belong to technical field of buildings.
Background technology
Steel bar truss floor support plate belongs to the one without supporting die mould combination floor support plate; Steel bar girder is in backstage processing space sizing processing, site operation needs first to be used by contour plate peg to be fixed on girder steel, place steel bar girder again and carry out colligation, check and accept after-pouring concrete, steel bar girder floor plates belongs to the one without supporting die mould combination floor support plate; Steel bar girder is that site operation needs first to use peg to be fixed on girder steel contour plate, then places steel bar girder and carry out colligation, checks and accepts after-pouring concrete in backstage processing space sizing processing.
Existing steel bar girder floor plates is made up of galvanized sheet and steel bar truss welding, larger owing to often organizing space between truss, make the floor after building mix earth and cause much unnecessary waste, pass through hollow cavity, concrete can be saved in construction and all kinds of technical data of floor plates can be improved, making floor plates mechanical structure more reasonable, improve floor plates damping, sound insulation value, for this reason, we propose a kind of steel bar girder floor plates adding hollow cavity.
Summary of the invention
The technical problem to be solved in the present invention overcomes existing defect, a kind of steel bar girder floor plates adding hollow cavity is provided, pass through hollow cavity, concrete can be saved in construction and all kinds of technical data of floor plates can be improved, make floor plates mechanical structure more reasonable, improve floor plates damping, sound insulation value, effectively can solve the problem in background technology.
In order to solve the problems of the technologies described above, the invention provides following technical scheme:
The invention provides a kind of steel bar girder floor plates adding hollow cavity, comprise floor plates body, described floor plates body comprises truss and hollow cavity, described truss comprises web member reinforcing bar, be provided with the reinforcing bar that winds up between described a pair web member reinforcing bar, described in wind up reinforcing bar and web member reinforcement welding, bottom described web member reinforcing bar, side is provided with lower edge reinforcing bar, described lower edge reinforcing bar and web member reinforcement welding, described web member reinforcing bar side is provided with hollow cavity.
As a preferred technical solution of the present invention, described hollow cavity is galvanized sheet metal cone cabinet boxlike cavity plate, steel plate thickness 0.5 millimeter.
As a preferred technical solution of the present invention, two upper angular rollings of described hollow cavity are shaped with right angle step.
As a preferred technical solution of the present invention, described hollow cavity is provided with cavity lateral bending, and described cavity side is bent into 100 degree, formed reverse taper and with web member parallel reinforced steel bar.
As a preferred technical solution of the present invention, bottom described hollow cavity, roll into the parallel edges ear of two Ω shape 30 centimeter length, make the hollow cavity prestressing force card forelock bottom web member of himself.
The beneficial effect that the present invention reaches is: a kind of steel bar girder floor plates adding hollow cavity, pass through hollow cavity, make floor plates mechanical structure more reasonable, improve floor plates damping, sound insulation value, floor plates 30% concreting amount can be saved and build the time, avoid owing to often organizing the waste that between truss, space causes the floorslab concrete after a lot building unnecessary comparatively greatly, by adopting steel cavity, add floor plates intensity, hollow cavity can at factory's continuous-flow type production line roll forming, achieve mechanization production, be conducive to arrangement of bar spacing even, thickness of concrete cover is consistent, improve the construction quality of floor.
