Description
Technical Field
The utility model belongs to the technical field of the building and specifically relates to a steel bar truss template connecting piece can be dismantled to self-supporting.
Background
The steel bar truss floor bearing plate is a building product which welds stressed steel bars in a floor slab into a steel bar truss in a factory and fixedly connects the steel bar truss with a bottom die to form the integration of the bottom die and the stressed steel bars. During construction, the steel bar truss floor bearing plate is fixed between the two bearing beams and is directly poured by concrete, the bottom die bears the gravity of the concrete, and the steel bar truss provides unsupported rigidity for the bottom die. Compare with the traditional building carrier plate that supports the concrete through bottom formwork, the construction progress has been accelerated to steel bar truss building carrier plate formula, has strengthened the supporting effect.
In order to recycle the bottom die after the pouring is finished, a steel bar truss floor support plate capable of detaching the bottom die appears in the prior art, and when the concrete is poured and is solidified, the bottom die can be detached so as to be recycled. The steel bar truss and the bottom die of the floor support plate are connected through the connecting fastener, the connecting fastener realizes detachable connection between the steel bar truss and the bottom die, but the bottom surface of the existing connecting fastener can not be tightly attached to the top surface of the bottom die frequently, and after concrete is poured, the problem of hollowing can be caused, so that the bottom of the connecting fastener is disconnected from the concrete, and the quality of the steel bar truss floor support plate is seriously influenced.
The notice number is: chinese patent CN208122060U discloses a connecting fastener for detachably fixing a steel bar truss to a bottom die, the connecting fastener is provided with a clamping groove, a lower chord steel bar of the steel bar truss is clamped in the corresponding clamping groove, the bottom of the connecting fastener is detachably fixed to the bottom die, the bottom of the connecting fastener is tightly attached to the bottom die, and a groove is formed in the bottom surface of the connecting fastener. The bottom surface that connects the fastener and hug closely the die block is seted up flutedly, and when concreting, the concrete can flow into in the recess voluntarily for the concrete of connecting the fastener bottom and the concrete of floor connect into whole, thereby can prevent effectively that the hollowing from appearing, and then avoid the bottom concrete of connecting the fastener to break.
The connecting fastener is generally made of plastic parts, because the connecting fastener is larger in size in consideration of the strength of the connecting fastener, the proportion of concrete after concrete pouring is relatively smaller, and the overall strength after pouring is not very high.
SUMMERY OF THE UTILITY MODEL
Not enough to prior art exists, the utility model aims at providing a steel bar truss template connecting piece can be dismantled to self-supporting, this connecting piece has changed holistic structure and is small and exquisite more in volume, makes the overall structure intensity after having pour with the concrete together higher.

Through adopting above-mentioned technical scheme, when concreting, the concrete can flow in the bottom of metal connecting plate automatically for the concrete of connecting piece bottom and the concrete connection of floor become whole, thereby can effectively reduce the appearance of hollowing, and then the phenomenon of disconnection appears in the bottom concrete that reduces the connecting piece.
The utility model discloses further set up to: the cross section of the plastic base is in a hexagon formed by combining two identical right-angle trapezoid large bottom edges.
Through adopting above-mentioned technical scheme for connecting piece overall structure is more firm.
The utility model discloses further set up to: and two connected arc surfaces are arranged on the inclined surface of the plastic base.
Through adopting above-mentioned technical scheme, the arc surface setting that two are connected makes connecting piece and concrete placement back bonding ground more, and is whole more firm.
The utility model discloses further set up to: the plastic base is fixedly arranged on the metal plate through injection molding.
The utility model discloses further set up to: the metal plate is connected with the plastic base in a sliding mode, limiting plates which are limited up and down are arranged on the side wall of the metal plate, and corresponding sliding grooves are formed in the plastic base.
Through adopting above-mentioned technical scheme, plastic base and metal sheet components of a whole that can function independently set up for it is more simple on the manufacturing process, also convenient transportation simultaneously, also can conveniently change when the plastic base on the connecting piece appears damaging.
The utility model discloses further set up to: the limiting plate is provided with screw holes with the same threaded holes, and the threaded holes correspond to the screw holes up and down.
Through adopting above-mentioned technical scheme, when fixing the connecting piece on the die block, the bolt is selected in the screwed hole also the screw in simultaneously for it is more stable to be connected between plastic base and the metal sheet.
To sum up, the utility model discloses a beneficial technological effect does:
1. through combining plastic base and metal sheet for the holistic structure of connecting piece is more small and exquisite, makes the abundant atress of main force reinforcing bar both sides concrete, and intensity is higher, and the manual machine of fixed dimension is dual-purpose, and construction speed is fast, the benefit of improving.
2. And the metal plate is adopted, so that the adhesive force between the connecting piece and the poured concrete is better.
