Description

Concrete mould convenient to concrete demoulding

Technical Field

The utility model relates to a construction machinery building technical field, specific concrete mold convenient to concrete demolding that says so.

Background

To the utility model discloses retrieve, patent name: there is a combined reusable concrete mould (patent number: CN 201821961315.2), it relates to a combined reusable concrete mould, including four angle moulds and four side moulds, the described angle mould is a right-angle metal piece, and the described side mould is a rod-like metal piece; the four angle molds and the four side molds are sequentially connected at intervals to form a rectangular concrete mold, the four angle molds are respectively arranged at the four corners of the concrete mold, and the four side molds are respectively arranged at the four sides of the concrete mold; each joint of the angle die and the side die comprises a crimping surface arranged on the angle die and a crimping matching surface arranged on the side die; the crimping surface and the outer side surface of the concrete mold form an included angle alpha which is 30-60 degrees, and the crimping matching surface is matched with the crimping surface; and in the splicing state, the crimping surface is in crimping fit with the crimping fitting surface.

Disclosure of Invention

The utility model discloses aim at overcoming prior art's defect, provide a concrete mould convenient to concrete demoulding, solve the problem of concrete test piece drawing of patterns.

In order to solve the technical problem, the utility model discloses a realize like this:

a concrete mould convenient for demoulding concrete comprises an upper mould and a lower mould, wherein the lower mould is a cuboid steel plate, and bolt holes are formed in the lower mould; the upper die is formed by processing a cuboid steel plate, the length and the width of the upper die are the same as those of the lower die, the thickness of the upper die is the same as that of a concrete test piece, a forming cavity with the same shape as that of the test piece is arranged in the middle of the upper die, and one side of the forming cavity is connected with the wide edge of the upper die to form a hollow groove; the upper die is provided with a bolt hole corresponding to the lower die, and the upper die and the lower die are fixed by penetrating the bolt hole through a bolt.

The utility model has the advantages that: simple structure, the preparation is convenient, can easily realize the test block drawing of patterns under the condition of not damaging the concrete test block, is fit for using widely.

Drawings

The invention will be described in further detail with reference to the following drawings and embodiments:

FIG. 1 is a top view of an upper mold.

Fig. 2 is a side view of the upper mold.

Fig. 3 is a plan view of the lower mold.

Fig. 4 is a side view of the lower mold.

Detailed Description

As shown in fig. 1-4: a concrete mould convenient for demoulding concrete comprises an upper mould and a lower mould, wherein the lower mould 1 is a cuboid steel plate, and a bolt hole 2 is arranged on the lower mould; the upper die is formed by processing a cuboid steel plate, the length and the width of the upper die are the same as those of the lower die, the thickness of the upper die is the same as that of a concrete test piece, a forming cavity 3 with the same shape as that of the test piece is arranged in the middle of the upper die, and one side of the forming cavity is connected with the wide edge of the upper die to form a hollow groove 4; the upper die is provided with a bolt hole corresponding to the lower die, and the upper die and the lower die are fixed by penetrating the bolt hole through a bolt.

Use preparation of tensile properties test piece for example in preparation JC/T-2461 supple food 2018, the utility model discloses constitute by upper and lower two parts, lower mould 1 is that a cuboid steel sheet is equipped with bolt hole 2, goes up the mould and is formed by a cuboid steel sheet processing, and length and width are the same with the lower mould, and thickness is the same with preparation concrete test piece thickness, goes up the mould middle part and has the concrete shaping chamber 3 the same with the test piece shape, and the cavity links to each other with last mould broadside middle part, forms dead slot 4. After the upper die is manufactured, the empty groove needs to be spread for a certain distance to be kept under the action of no external force, and the empty groove is 2-3cm wider than the original empty groove. When the die is assembled, the upper die and the lower die are fixed together to align the bolt holes 2, meanwhile, the two ends of the upper die are aligned with the lower die, and then the bolts are screwed. After the concrete slurry is added into the fixed mould, the empty slot is plugged by a rubber gasket to prevent slurry leakage. When demoulding, the empty groove end needs to be fixed by the fixing device, then the bolt is unscrewed, the fixing device is loosened, and the empty groove end of the upper die can automatically bounce open, so that the concrete is separated from the side wall of the die, and demoulding is convenient.

Claims

1. The utility model provides a concrete mold convenient to concrete demoulding which characterized in that: the device comprises an upper die and a lower die, wherein the lower die is a rectangular steel plate, and a bolt hole is formed in the lower die; the upper die is formed by processing a cuboid steel plate, the length and the width of the upper die are the same as those of the lower die, the thickness of the upper die is the same as that of a concrete test piece, a forming cavity with the same shape as that of the test piece is arranged in the middle of the upper die, and one side of the forming cavity is connected with the wide edge of the upper die to form a hollow groove; the upper die is provided with a bolt hole corresponding to the lower die, and the upper die and the lower die are fixed by penetrating the bolt hole through a bolt.
