Description
Technical field
The present invention relates to a kind of floor support plates more particularly to a kind of steel bar truss floor support plate and preparation method thereof, belong to steel knot
Structure field.
Background technique
Steel bar truss floor support plate is a kind of construction material to grow up emerging in recent years, is had been widely used and various steel knots
Building is built, in the construction of municipal (highway, bridge).Steel bar truss floor support plate be made by first by three kinds of specifications (wind up, under
String and web member) reinforcing bar combination (web member containing bends) welding processing at steel bar girder, then using spot welding by steel bar girder and bottom
Form assembly is integrally welded.The steel bar truss floor support plate for producing factory normalization is only needed to be laid immediately on beam when construction,
Then the construction of relatively simple seat shoulder bar and distribution bar is carried out, so that it may carry out concreting.Due to steel bar girder
Steel bar girder in floor support plate can undertake the structure stress of plate, and bed die galvanized steel plain sheet can substitute traditional plank sheathing, using reinforcing bar
The work such as truss floor support plate can greatly reduce the binding of building-site reinforcing bar, end template is assembled and disassembled, raising reinforced concrete floor (or road
Face, bridge floor etc.) construction efficiency, save the cost.But there is Railway Project than more prominent in the prior art: 1, end template and reinforcing bar purlin
In frame welding process, because of the thickness problem of end template, frequently results in truss web and burn-through phenomenon occur in bottom plate bond pad locations, give
Concrete on construction site, which pours, brings spillage quality problems；2, it when end template lapping construction, because of tectonic sieving problem itself, does not set
Mortar leakage prevention shelves mouth is set, causes overlap joint cannot be close, brings spillage risk to subsequent concrete pouring construction.
Summary of the invention
The present invention mainly solves the deficiencies in the prior art, provides a kind of compact-sized height, overall performance is outstanding
A kind of steel bar truss floor support plate and preparation method thereof.
Above-mentioned technical problem of the invention is mainly to be addressed by following technical proposals:

Preferably, described is left from upward left mating chamber is formed between backset mouth and end template, the right side is certainly
Backset mouth extends to left mating chamber and matched from backset mouth with a left side.
A kind of preparation method of steel bar truss floor support plate, sequentially includes the following steps:
(1), simulation is conceived and is designed:
The design concept of steel bar girder floor plates and end template is to be improved by a kind of design of end template, and add " Y "
The protrusion construction of shape reaches requirement of the bottom plate without welding trace and increase welding surface and intensity；And by designing two side of end template or so
For one kind from backset mouth, i.e., the concrete gravity amount when concrete is poured carries out gravity locking, solves the problems, such as spillage；
(2), prepared by end template:
1, the substrate of end template we selected a kind of preferably zinc-plated cold-rolled steel sheet of tensile property, molding equipment is made；
2, Y-shaped protrusion construction and two sides of left and right make from the end template of backset mouth, improve first to making apparatus:
It constructs contact roller design selection hard alloy steel suitable for reading to Y-shaped protrusion to be made, and increase multiple tracks additional lock bearing up pulley to make " Y "
Configured openings reach preset requirement；
It selects lateral more wheel shaping technologies and increases flexible nylon wheel assistant formation technology and two sides of left and right are made from backset mouth,
So that concrete grout is not leaked outside from two side seam crossings, reaches self-locking function effect；

The product of existing steel bar girder floor plates is made；
(4), it tests:
With the obtained of end template be made by resistance spot welding after steel bar girder combination, end template bottom surface without welding trace and
Burnt hole, weld strength reach requirement.
Background template and steel bar truss welding form steel bar truss floor support plate product.By the improvement to end template, from original
The convex shape come, is improved to Y-shaped shape for lugs, increases bottom muscle, welding surface is not direct to be contacted with baseplane, to keep away
Exempt from end template by burn-through, while increasing welding surface.
By the transformation to two edge lap interface of end template, anti-leakage structure plate washer (from backset mouth) is added, is buckled well in overlap joint
Afterwards, during to two side stretchings, that is, during casting concrete, overlap joint interface is automatic tight under the effect of gravity
Contracting, mortar leakage prevention.Simultaneously because adding plate washer construction, the rigidity and stress intensity of end template lap position are also enhanced.
One of present invention steel bar truss floor support plate and preparation method thereof can prevent end template burn-through, prevent leakage
Starch phenomenon.
