Abstract

The utility model discloses a kind of concrete cast iron die trial, it is characterized in：Including retainer ring and square bottom plate, cheek board is respectively articulated with four sides of bottom plate, four cheek boards are rotated up forming die cavity, and Fixing shrink ring is located at the upper end of four cheek boards；The upper end of cheek board is provided with shrinkage pool, and the ring ear of protrusion is provided with the outside of retainer ring.It is of the present utility model simple in construction, using bottom plate and four rotatable cheek board structures, the combination of die trial is completed located at four cheek board upper ends with Fixing shrink ring, therefore it combines very convenient quick, likewise, its fractionation is convenient to quickly, as long as removing retainer ring；Shrinkage pool is inserted with specific purpose tool during the demoulding, increases the torque for rotating cheek board with this, therefore is easy to rotate cheek board, and then removes test specimen.

Description

A kind of concrete cast iron die trial

Technical field

The utility model belongs to technical field of building construction, more particularly, to a kind of concrete cast iron die trial.

Background technology

In building construction, in order to test or examine the compressive property of concrete, it is necessary to make the concrete of square build Test specimen.Making test specimen then needs square die trial, and in the market still without the concrete test die of unified standard, some use plastics Manufactured die trial, it is a uniform shapes, therefore the demoulding is highly difficult, and some castiron die trials, its cheek board can be torn open Open, it is so conveniently stripped, but relation is typically spirally connected to fix by screw bolt and nut between cheek board, so that die trial Combination and split that speed is slower, and bolt is easily adhered cement in use for die trial, cause it to combine and split more It is not easy, it is therefore necessary to improved.

The content of the invention

The purpose of this utility model is to be directed to above-mentioned the shortcomings of the prior art, there is provided a kind of concrete cast iron die trial, It, which has, is convenient in demoulding, and the characteristics of quick is combined and split in die trial.

To achieve these goals, technical scheme is used by the utility model：A kind of concrete cast iron die trial, including The bottom plate of retainer ring and square, cheek board has been respectively articulated with four sides of the bottom plate, four cheek boards are rotated up shape Into die cavity, the Fixing shrink ring is located at the upper end of four cheek boards；The upper end of the cheek board is provided with shrinkage pool, the fixation The ring ear of protrusion is provided with the outside of ring.

The bottom of the bottom plate is provided with boss.

After said structure, the utility model is compared to the prior art advantageously：Knot of the present utility model Structure is simple, and using bottom plate and four rotatable cheek board structures, examination is completed located at four cheek board upper ends with Fixing shrink ring The combination of mould, therefore its combination is very convenient quick, likewise, its fractionation is convenient to quickly, as long as removing retainer ring i.e. Can；Shrinkage pool is inserted with specific purpose tool during the demoulding, increases the torque for rotating cheek board with this, therefore is easy to rotate cheek board, is entered And remove test specimen.

Brief description of the drawings

Fig. 1 is top view of the present utility model.

Fig. 2 is front view of the present utility model.

Embodiment

As described below is only preferred embodiment of the present utility model, does not therefore limit protection model of the present utility model Enclose, the utility model is further illustrated with reference to the accompanying drawings and examples.

Embodiment, as shown in Fig. 1 to Fig. 2：A kind of concrete cast iron die trial, including the bottom plate 2 of retainer ring 1 and square, Cheek board 3 is hinged with by hinge 8 respectively on four sides of the bottom plate 2, four cheek boards 3 are rotated up forming die cavity 4, institute State the upper end that retainer ring 1 is set in four cheek boards 3；The upper end of the cheek board 3 is provided with shrinkage pool 5, the retainer ring 1 Outside is provided with the ring ear 6 of protrusion.

Preferably, the bottom of the bottom plate 2 is provided with the boss 7 for being higher by hinge 8, can prevent when die trial from using because of collision and Hinge 8 is damaged, and then avoids result in when four cheek boards 3 combine and can not mutually be fitted close.

The upper end that retainer ring 1 is sheathed on four cheek boards 3 by the utility model can complete the combination of die trial, therefore its group Close very convenient quick, likewise, its fractionation is convenient to quick, as long as removing retainer ring 1, ring ear 6 is solid to removing It is helpful to determine ring 1；Shrinkage pool 5 is inserted with specific purpose tool during the demoulding, torque when rotating cheek board 3 is increased with this, therefore is easy to Cheek board is rotated, and then removes test specimen.
