Description
Technical field
The utility model relates to drawing die, is specifically related to surrounding reinforcing bar built-in type drawing die.
Background technology
Reinforced concrete refer to by concrete, add reinforcing bar with it co-operation improve a kind of combined material of concrete character, by reinforcing bar, bear pulling force wherein, concrete is born compressive stress part, thereby both co-operation are improved the mechanical property of concrete tensile strength deficiency, for the modal a kind of form of the concrete of putting more energy into, be widely used in the middle of building, science of bridge building, shipbuilding industry, machinery.
When the physical property of reinforced concrete is tested, generally can make corresponding test block with mould, as made reinforced concrete tension test block by reinforced concrete drawing die.But the mould that reinforced concrete stretched part is used at present, common complex structure, concreting or unloading process are cumbersome, make troubles to later stage tested steel reinforced concrete tensile strength.
Utility model content
Problem to be solved in the utility model is that existing reinforced concrete drawing die and test specimen do not need to take apart, the problem of integrated stretching.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopts is to provide a kind of surrounding reinforcing bar built-in type mould, comprise by a horizonal base plate and two fixing mold slots that form of vertical side plate, on the medial surface at the two ends of two blocks of described vertical side plates, be interspersed with respectively the middle part plate being oppositely arranged, the outside of two blocks of described middle part plates is fitted with respectively an end plate, the lateral surface of described middle part plate is provided with draw ring, around described draw ring, be circumferentially laid with a plurality of through holes, the center of described end plate has circular hole, described circular hole be circumferentially with the threaded hole that a plurality of and described through hole is oppositely arranged.
In such scheme, between the described through hole of two blocks of described middle part plates, be penetrated with main reinforcement, the outer end of described main reinforcement is stretched out the lateral surface of described middle part plate and is installed with nut.
In such scheme, in described threaded hole, screw in short thread steel, described nut is withstood to fix described main reinforcement in the inner of described short thread steel.
In such scheme, the quantity of described through hole is four.
The utility model, on the medial surface at the two ends of the vertical side plate of mold slots, be interspersed with middle part plate, the lateral surface of middle part plate is provided with draw ring, middle part plate and concrete sample form an integral body, directly the draw ring on the plate of middle part is fixed on tension test instrument and can be tested, simple in structure, easy to operate, do not need form removal can carry out tension test, there is good practicality.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is the structural representation of middle part plate in the utility model;
Fig. 3 is the structural representation of the utility model end plates.
Embodiment
Below in conjunction with Figure of description, the utility model is described in detail.
As shown in Figure 1, the surrounding reinforcing bar built-in type drawing die that the utility model provides comprises by a horizonal base plate 10 and two fixing mold slots that form of vertical side plate 20, the outside that is interspersed with respectively 40, the two blocks of middle part plates 40 of middle part plate that are oppositely arranged on the medial surface at the two ends of two blocks of vertical side plates 20 is fitted with respectively an end plate 30.
As shown in Figure 2, on the lateral surface of middle part plate 40, center is provided with draw ring 41, for when test tensile strength, testing tool clamping stretching concrete sample, around draw ring 41 circumferential uniform, four through holes 42 are set, for four main reinforcements of moulding by casting reinforced concrete test specimen, be applied in respectively two respective through hole 42 on the plate 40 of middle part, nut of spinning after the lateral surface of middle part plate 40 is stretched out respectively in the outer end of main reinforcement.
As shown in Figure 3, end plate 30 center has circular hole 31, circular hole 31 be circumferentially with adjacent middle part plate 40 on the threaded hole 32 that is oppositely arranged of through hole 42, the interior screw-in short thread of threaded hole 32 steel, the inner of short thread steel is withstood nut main reinforcement is fixed.
Using method of the present utility model is as follows:
The first step: respectively two blocks of middle part plates 40 are inserted on vertical side plate 20, are formed for holding concrete space between two blocks of middle part plates 40;
Second step: respectively four main reinforcements are inserted from a middle part plate 40, and insert out from another piece middle part plate 40, make the two ends of main reinforcement lay respectively at the outside of middle part plate 40;
The 3rd step: fix a nut in the external part spinning of main reinforcement respectively;
The 4th step: screw in short thread steel from the outside of two end plates 30 through threaded hole 42 respectively, the inner of short thread steel is withstood nut main reinforcement is fixed;
The 5th step: to casting concrete in mould, after concrete thoroughly solidifies, screw out short thread steel;
The 6th step: respectively two blocks of middle part plates 40 are extracted out together with reinforced concrete, made its break away from moulds groove, form reinforced concrete test specimen.
The 7th step: the draw ring 41 in plate 40 outsides, two middle parts is separately fixed on tension test instrument and is tested.
The surrounding reinforcing bar built-in type drawing die that the utility model provides, the lateral surface of middle part plate is provided with draw ring, and middle part plate and concrete sample form an integral body, directly the draw ring on the plate of middle part is fixed on tension test instrument and can be tested, simple in structure, easy to operate, do not need form removal can carry out tension test, there is very high practicality.
The utility model is not limited to above-mentioned preferred forms, and anyone should learn the structural change of making under enlightenment of the present utility model, every with the utlity model has identical or close technical scheme, within all falling into protection domain of the present utility model.
