Abstract
The utility model discloses a mold for preparing a reinforced concrete test block. The mold for preparing the reinforced concrete test block comprises a mold body and a bracket. The mold body is of a case type coverless structure. First circular holes used for being penetrated through by reinforcing steel bars are formed in a block side plate of the mold body. The bracket is formed by a vertical supporting plate and supporting blocks arranged on two side of the supporting plate. Semi-circular holes used for supporting the stretching-out parts of the reinforcing steel bars are formed in the top portion of the supporting plate, and the bottom portions of the first circular holes are aligned to the bottom portions of the semi-circular holes. The mold for preparing the reinforced concrete test block can prevent the position of the reinforcing steel bars from deviating, and improves the integral quality of the reinforced concrete test block.
Description
Technical field
The utility model relates to a kind of mould that is used to prepare the armored concrete test block.
Background technology
For research reinforcing bar and concrete binding stress, generally be by the drawing test specimen being carried out experimental test, obtaining reinforcing bar and the concrete bond stress between the two and the relation of slippage according to test data then.
Usually when making the drawing test specimen, all adopt the mode of embedded bar, promptly before casting concrete, build again at the assigned address embedded bar.Traditional mould has certain restriction on aspect the size, only possess 150 * 150 * 150mm, 100 * 100 * 100mm, 250 * 250 * 250 etc. such as general building laboratory concrete mold.
The greatest problem that traditional mould exists is: for the drawing test specimen, because size is less, reinforcing bar position is difficult to reach the appointment requirement, occurs the small eccentricity phenomenon easily, does not also reach expection experimental test result; Therefore if adopt traditional Mold Making drawing test block, be in the fixing and process of vibrating of reinforcement location, all be difficult to guarantee reinforcing bar complete perpendicular to the face of building.
In addition, early stage mould all is a cast iron part generally, though have superiority in reuse, the making of some special test blocks is difficult for satisfying.On the one hand, though it is feasible that steel are holed, can cause certain waste, and the existence owing to original form removal device makes that perforate itself also is not facile something on traditional cast iron mould, and the end plate of both mold ends is fixed, and makes that the test block have reinforcing bar can't the demoulding; Instantly have the production method of a lot of test specimens to adopt mould of plastics, but it has not enough place equally: such as the repeated utilization rate of mould of plastics is low; For the tailor-made expense height of the test piece mould of certain special size.
The utility model content
Technical problem to be solved in the utility model provides a kind of mould that is used to prepare the armored concrete test block, and this mould that is used to prepare the armored concrete test block can avoid reinforcement location to depart from, and improves the total quality of armored concrete test block.
The technical solution of utility model is as follows:
A kind of mould that is used to prepare the armored concrete test block comprises die ontology and carriage; Die ontology is box uncovered structure; The side plate of die ontology is provided with first circular hole (5) that is used to pass reinforcing bar; Carriage is made up of a vertical supporting plate (6) and the piece (7) that is arranged on the supporting plate both sides; Be provided with the semicircle orifice (8) that is used for the spacer bar extension at the top of supporting plate (6) or be provided with second circular hole that is used for the spacer bar extension on supporting plate (6), the bottom of the semicircle orifice (8) or second circular hole is concordant with the bottom of first circular hole (5).
Described die ontology is spliced by bolt (3) or screw by polylith square plate (2).
Also be provided with timber wedge (1) between the described polylith square plate (2).
Be provided with dividing plate (4) in the described die ontology, dividing plate (4) is divided into two mould space that size is identical with the inner chamber of die ontology, is equipped with first circular hole (5) on relative two side plates of die ontology, and these two side plates are all parallel with dividing plate; Described carriage is two covers.
The radius of described first circular hole (5), second circular hole and semicircle orifice (8) is 10mm, and the appearance and size of die ontology is 560mm * 190mm * 190mm, and the thickness of square plate (2) is 20mm.
Beneficial effect:
The mould that is used to prepare the armored concrete test block of the present utility model, owing to designed band carriage in midair, reinforcing bar is by good location when making cast, thereby make reinforcing bar all the time with the central lines of die ontology length direction, it is eccentric to avoid reinforcing bar to occur when cast, thereby ultimate guarantee armored concrete test block quality helps providing basic guarantee smoothly for the follow-up test at the armored concrete test block.

Fig. 1 is the structural representation (figure a, b and c are respectively vertical view, front view and side view) of die ontology.
Fig. 2 is the structural representation (figure a, b and c are respectively vertical view, front view and side view) of carriage.
Label declaration: label declaration: the 1-timber wedge, the 2-square plate, the 3-bolt, the 4-dividing plate, 5-first circular hole, the 6-supporting plate, 7-props up piece, the 8-semicircle orifice.
The specific embodiment
Below with reference to the drawings and specific embodiments the utility model is described in further details:
Embodiment 1:
Shown in Fig. 1-2, a kind of mould that is used to prepare the armored concrete test block comprises die ontology and carriage; Die ontology is box uncovered structure; The side plate of die ontology is provided with first circular hole 5 that is used to pass reinforcing bar; Carriage is made up of a vertical supporting plate 6 and a piece 7 that is arranged on the supporting plate both sides; Be provided with the semicircle orifice 8 that is used for the spacer bar extension at the top of supporting plate 6, the bottom of semicircle orifice 8 is concordant with the bottom of first circular hole 5.
Described die ontology is spliced by bolt 3 (or screw) by polylith square plate 2.
Also be provided with timber wedge 1 between the described polylith square plate 2.
Be provided with dividing plate 4 in the described die ontology, dividing plate 4 is divided into two mould space that size is identical with the inner chamber of die ontology, is equipped with first circular hole 5 on relative two side plates of die ontology, and these two side plates are all parallel with dividing plate; Described carriage is two covers.
The radius of described first circular hole 5 and semicircle orifice 8 is 10mm, and the appearance and size of die ontology is 560mm * 190mm * 190mm, and the thickness of square plate 2 is 20mm.
Described square plate and carriage adopt wood materials, and mould is made at the concrete sample of 150 * 150 * 250 sizes, and this grinding tool can 2 armored concrete test blocks of disposable formation.
Connector adopts timber wedge and bolt, and wherein timber wedge makes entire die tight, and bolt guarantees that mould does not fall apart in the process of vibrating.
Therefore at preparation drawing test specimen (being the armored concrete test block), reinforcing bar is not all to imbed, and for fixing reinforcing bar position, makes it at horizontal level, has designed carriage.
Hole on die ontology and the carriage will determine according to the size of actual reinforcing bar, should accomplish that as far as possible reinforcing bar just in time passes and do not stay excessive space.When the form removal, should mould be carried out certain knocking to the test specimen of building with hammer, and then form removal.
Embodiment 2:
Difference from Example 1 is, described semicircle orifice with radius just as second circular hole replace, second circular hole is arranged on the supporting plate, the bottom of second circular hole is concordant with the bottom of first circular hole.If adopt the second circular hole spacer bar, after then the armored concrete test block completes, need carriage be taken out from the external part of reinforcing bar.
