Abstract
The invention provides a reversed bending device for steel bars. The reversed bending device comprises a bottom plate, a plurality of supporting legs mounted on the bottom plate, a turning plate mounted at the upper part of each supporting leg and a tray mounted on each turning plate, which are connected to form a steel bar reversed bent structure; each tray is rectangular and a semi-arc-shaped limiting groove is formed in the upper middle part of each tray; a dovetail-shaped convex groove matched with each turning plate is formed in the bottom of each tray. The reversed bending device provided by the invention can be used in cooperation with any tensile testing machines with a pushing function, and can also be suitable for the steel bars with different sizes by replacing the trays; the turning plates can freely rotate along with the movement tendency of a testing piece so that the problems of a reversed bending test are effectively solved; meanwhile, the whole testing process is simple and convenient, efficient, safe and accurate; the testing cost of a library is reduced.
Description
Technical field
The present invention relates to back-flexing device, relate in particular to a kind of for the turnover plate type that coordinates with universal testing machine, with turning adjustable reinforcing bar back-flexing device.Belong to building engineering field.
Background technology
Reinforcing bar, as the basic material in building materials, is widely used in each engineering field.Therefore,, for the test of reinforcing bar material mechanical performance, become the important channel of inspection reinforcing bar actual mass.But, due to the application characteristic of reinforcing bar, be different from the Mechanics Performance Testing of other metal materials, requirement in " bending of YB/T5126-concrete reinforcement steel and reverse bending test method ", need to test by back-flexing, measure the back-flexing deformation performance of reinforcing bar after bending ductility distortion and timeliness.
The principle of reverse bending test is: use common bending apparatus, by bar bending to 90 °, then, take off testpieces, carry out timeliness thermal treatment at the temperature of 100 DEG C, its temperature retention time is at least 30min; In air, be freely cooled to after room temperature again, on back-flexing equipment, again carry out back-flexing to 120 °.
Because existing reverse bending test machine is substantially all independent individual, or a part for large-sized multifunction testing machine, function is incomplete, and it is not too convenient that test is got up.The equipment of manufacturing according to replaced " YB/T5126-1993 (steel bar plane reverse bending test method) " specialized designs, more emphasize that globality is multi-functional, but structure relative complex, there is certain disconnection with new standard concept, and, need to purchase separately, for the in type laboratory of working range, all desirable not to the utmost from design concept and cost payout.
Background technology
Summary of the invention
Fundamental purpose of the present invention is to overcome the above-mentioned shortcoming that prior art exists, and a kind of improved reinforcing bar back-flexing device is provided, and it not only can be used in conjunction with any cupping machine with lower compression functions; And, can also be applicable to different size reinforcing bar by pallet-changing, and rotate by turnover panel is can pursuit test part movement tendency personal, effectively solve reverse bending test problem; Meanwhile, make whole process of the test easy, efficient, safe, accurate; Reduce the experimentation cost in laboratory.
The object of the invention is to be realized by following technical scheme:
A kind of reinforcing bar back-flexing device, is characterized in that: comprising: a base plate, be arranged on the several supporting legs on base plate, the turnover panel that is arranged on each supporting leg top, turnover panel a pallet is installed, by the above-mentioned reinforcing bar back-flexing structure that connects and composes.
Reinforcement gusset is installed on described supporting leg.
Described pallet is rectangle, and upper middle part is provided with half arc-shaped limit groove, and bottom is provided with the dovetail tongue matching with turnover panel.
The bottom of described turnover panel is provided with for tray top and coordinates the dovetail groove of installing.
Beneficial effect of the present invention: the present invention is owing to adopting technique scheme, and it not only can be used in conjunction with any cupping machine with lower compression functions; And, can also be applicable to different size reinforcing bar by pallet-changing, and rotate by turnover panel is can pursuit test part movement tendency personal, effectively solve reverse bending test problem; Meanwhile, make whole process of the test easy, efficient, safe, accurate; Reduce the experimentation cost in laboratory.

Embodiment
As shown in Fig. 1-Fig. 5 B, the present invention includes: a base plate 6, mode with bolts are arranged on several supporting legs 4 on base plate 6, supporting leg angle display disc 3 is housed, adopt shaft hole matching mode to be arranged on the turnover panel 2, turnover panel 2 on each supporting leg 4 tops a pallet 1 is installed, by the above-mentioned reinforcing bar back-flexing structure that connects and composes.Wherein, supporting leg 4 is four, adopts respectively welding manner to be provided with and strengthen gusset 5 on each supporting leg 4; Pallet 1 is rectangle, and upper middle part is provided with half arc-shaped limit groove, and bottom is provided with the dovetail tongue matching with turnover panel 2; The bottom of turnover panel 2 is provided with for tray top and coordinates the dovetail groove of installing.
When use, by the present invention as for the centre position between the upper and lower crossbeam of universal testing machine.According to the external diameter of steel bar test part, select to be applicable to the pallet 1 of model, by steel bar test part prebuckling to 90 ° and two legs of steel bar test part are put into the semicircular arc pickup groove of pallet 1, adjust position, make the position of steel bar test part make the angle display disc 3 of two supporting leg 4 sides all point to 90 °.Then, the chuck of universal testing machine is installed pressing plate and is slowly pressed down, viewing angle display disc 3, and in the time that it points to 120 °, experiment stops.Universal testing machine entablature rises, and unloads steel bar test part.
The above, it is only preferred embodiment of the present invention, not the present invention is done to any pro forma restriction, any simple modification, equivalent variations and modification that every foundation technical spirit of the present invention is done above embodiment, all still belong in the scope of technical solution of the present invention.
