Detailed description of the invention
The embodiment 1 of steel bar truss floor support plate in the utility model: as depicted in figs. 1 and 2, this steel bar girder 1 floor support plate is a kind of bed die 3 easily detachable steel bar girder 1 floor support plate, primarily of steel bar girder 1, fastener 2 and bed die 3 are connected in sequence from the top down, steel bar girder 1 is triangular truss conventional in existing Construction of Steel Structure, bed die 3 is bamboo slab rubber, steel plate etc., bed die 3 is lifted on the bottom of steel bar girder 1 by fastener 2 by the removable mode be connected, with in the construction stage, be overlapped in roof beams by steel bar girder 1 and strength and stiffness are provided, cast-in-situ concrete held by bed die 3, and transfer loads on steel bar girder 1.Fastener 2 is made up of deck 21, trip bolt and sealing mat.The top of deck 21 is integrally formed with about two relative claws 22, the bottom of two claws 22 is opposing bending, with surrounded by the opposing depression in opposite flank bottom two claws 22 notch upward, the draw-in groove 23 to snap in from upside for the longitudinal chord muscle 11 of steel bar girder 1, draw-in groove 23 is C type groove, the cross-sectional profiles of the internal face of draw-in groove 23 is major arc, and the top of two claws 22 is provided with the guiding of opposing inclination gradually from bottom to top along 24, two guidings have connection also diminishing guiding enlarging from the top down above draw-in groove 23 between 24; The bottom of deck 21 offers the catching groove at the center of being in and is symmetricly set on the screwed hole of the catching groove left and right sides.The top center that sealing mat is 25 is integrally convexly equipped with the card column 26 with catching groove adaptation, the top of card column 26 be provided with adaptive with catching groove and can in catching groove around on the axis dop 27 in relative rotation of downward-extension; The edge of sealing mat 25 offers and two screwed holes corresponding screw via hole arranged respectively, two bolt through-holes are symmetricly set on the left and right sides of card column 26.When carrying out floor support plate assembling, under the guiding of guiding enlarging, two claws 22 are first opposing to be opened, after the longitudinal chord muscle 11 of steel bar girder 1 enters draw-in groove 23, two claws 22 close again in opposite directions, to be buckled in draw-in groove 23 by the longitudinal chord muscle 11 of steel bar girder 1, such deck 21 is just connected on the longitudinal chord muscle 11 of steel bar girder 1 by buckle; Then the card column 26 of sealing mat 25 plate is passed the central hole that bed die 3 is offered, be inserted in the catching groove bottom deck 21 in the mode that double buckle buckle connects, rotatory sealing pad 25 again, until the screw via hole of sealing mat 25 and the screwed hole of deck 21 snap to two side perforations that bed die 3 is offered, finally by trip bolt 28 from bottom to top successively through screw via hole, two side perforations and screw in screwed hole, bed die 3 is fixed on the downside of deck 21 by removable, then is connected on the longitudinal chord muscle 11 of steel bar girder 1 by deck 21 hanging.
The deck 21 of fastener 2 and sealing mat 25 adopt ABS, nylon, the poly-various engineering such as alum, PC, PBT plastics, draw-in groove 23 trough wall surface at deck 21 top and longitudinal chord muscle 11 outer peripheral face of steel bar girder 1 are affixed completely, avoid longitudinal chord muscle 11 to extrude from draw-in groove 23; Meanwhile, the edge of sealing mat 25 plays balanced support effect to bed die 3, to make the supporting force distribution suffered by bed die 3 better.
In the present embodiment, floor support plate is third generation truss floor support plate; assemble in inside plants completely; applying certain moment of torsion by manipulator squeezes in the fastener 2 of the engineering plastics material under bed die 3 by screw; achieve the connection of fastener 2 and bed die 3; by in lower edge muscle press-in fastener 2 after again the steel bar girder 1 processed being overturn; realize the connection of bed die 3 and steel bar girder 1; height between the groove bottom of the draw-in groove 23 of fastener 2 and the bottom surface of deck 21 is just equivalent to thickness of protective layer of floor slab, and all reinforcing bars are all protected.After the later stage, concrete strength reached respective standard, apply negative torque and shed trip bolt 28, just bed die 3 is removed easily, arrange and reclaim, get secondary recycling ready.Because bed die 3 does not substantially participate in bearing concrete gravity and working load in work progress, and it is more with the tie point of steel bar girder 1, therefore for substantially only playing the power transmission of block pulp holder concrete and ensureing that the soffit formwork such as plate, shaving board 3 moulded by the bamboo slab rubber of the smooth effect of soffit or other similar wood, as long as on-the-spot keeping is proper, more than 15 times can be recycled, greatly save the use of base plate.
Bed die 3 and steel bar girder 1 pass through fastener 2 snapping mutually, the gang form linked into an integrated entity, and in the construction stage, provide strength and stiffness by steel bar girder 1, concrete held by bed die 3, load passed to steel bar girder 1; In operational phase, steel bar girder 1 and concrete collaborative work, bear service load.Therefore, this gang form has profiled sheet combination or the fast advantage of the speed of application of non-combined floor support plate, and have again cast-in-place integral rigidity large, the advantage that anti-seismic performance is good, has wide prospect of the application.
The embodiment 2 of steel bar truss floor support plate in the utility model: as shown in Figure 3, the difference of the present embodiment and above-described embodiment is, screw via hole on sealing mat 225 and the screwed hole on deck 221 are all in centre, by trip bolt 228, sealing mat 225 is being assemblied in the process on deck 221 like this, trip bolt 228 can spinning on deck 221, also well can be aimed at the screwed hole on deck 221 easily.
In the above-described embodiments, trip bolt is connected in below deck by sealing mat by removable for bed die, and in other embodiments, sealing mat also can be got rid of, to be directly fixed on below deck by bed die by trip bolt.
In the above-described embodiments, draw-in groove is C type groove, and in other embodiments, draw-in groove also can be open-topped rhombus groove, square groove etc.
In the above-described embodiments; card column buckle is connected to the bottom of deck; in other embodiments; the mode that card column also can be threaded connection realizes connecting, and can reach the concrete component (comprising shear wall) adapting to different cover concrete like this by controlling the degree of depth of card column screw-in deck.In addition, card column and the deck that also can make Multiple Type also can reach the object adapting to different-thickness cover concrete, but comparatively speaking, the cost be threaded is lower, and compliance is also stronger.
In addition, in the present invention, floor support plate structure also can be used in the construction of shear wall.
The embodiment of floor support plate bed die fastener of the present utility model: in the present embodiment, the structure of floor support plate bed die fastener is identical with the structure of fastener in above-described embodiment, therefore repeats no more.But this fastener not only can be used on floor support plate, also can be used on shear wall.
