In order to realize above-mentioned task, the utility model adopts following technical scheme to realize:

A forming test mold for making concrete specimens, characterized in that: it includes a bottom plate, a horizontal vertical plate, a longitudinal vertical plate, a rib plate, a screw and a nut, and the upper surface of the bottom plate is provided with a first straight through Groove and the second through groove that longitudinally arranges, and described first through groove and second through groove surround the surface of bottom plate into two equal-area first sample area and second sample area; Said bottom plate second The outer side of the straight-through slot is provided with a local rib plate installation slot;

The horizontal vertical plate is a rectangular steel plate;

The longitudinal vertical plate is a rectangular steel plate, and a rib hole is provided in the middle of the longitudinal steel plate, and an ear plate is respectively provided on both sides of the longitudinal steel plate, and a pulling anchor hole is arranged on the ear plate; Anchor holes and tightened with nuts;

A circular rib hole is arranged on the rib plate, and the rib plate is inserted into the installation groove of the rib plate, and the corresponding relationship between the rib hole and the rib hole is set at the same circle center.

Further, the frame rib is a series of standard frame ribs with different diameters and sizes of the frame rib holes.

Beneficial effect:

1. The test mold is a combined structure, which is convenient for assembly and quick demoulding.

2. The reinforcement plate is an optional part, which can be selected and used according to different specifications of steel bars to improve the flexibility and convenience of use.

3. The bottom plate of the test mold is a standard structure, which can ensure the batch consistency and standardization of the test pieces and improve the quality of the test pieces.

4. After disassembly and assembly, it is convenient for transfer and storage.

Below in conjunction with accompanying drawing and embodiment the concrete content of the present utility model is described in further detail.

detailed description

The specific embodiments of the present utility model are given below, and it should be noted that the present utility model is not limited to the following specific embodiments, and all equivalent transformations done on the basis of the technical solutions of the present application all fall within the protection scope of the present utility model.

According to the above-mentioned technical scheme, as shown in Fig. 1 to Fig. 8, this embodiment proposes to make a concrete specimen forming test mold for testing the bonding force between concrete and steel bars, including a bottom plate 1, a horizontal vertical plate 2, and a vertical vertical plate 3 , frame rib plate 4, screw rod 5 and nut 6.

Bottom plate 1, with reference to Fig. 2 and Fig. 3, bottom plate 1 adopts thick steel plate to form through machining, adopts milling cutter on the upper surface of bottom plate 1 and mills out three transversely arranged first through grooves 11, two longitudinally arranged second through grooves. The straight-through slot 12 , the first straight-through slot and the second straight-through slot surround the surface of the bottom plate into two equal-area sample areas, marked as the first sample area 111 and the second sample area 112 .

The horizontal vertical plate 2 is a rectangular steel plate, as shown in FIG. 8 .

The longitudinal vertical plate 3 is a rectangular steel plate, and two circular holes are arranged in the middle of the longitudinal steel plate, which are the piercing holes 31, and the two circular piercing holes are aligned with the first sample area and the second sample area, An ear plate 32 is respectively provided on both sides of the steel plate, and anchor holes 33 are arranged on the ear plate.
