Description

Detachable concrete test block mold based on mortise and tenon joint structure

Technical Field

The utility model relates to a concrete test mold, in particular to a detachable concrete test block mold based on a mortise and tenon joint structure.

Background

Along with the construction and development of national highways, house buildings and bridges, the demand of concrete as an important raw material in construction engineering is gradually increased year by year. In the construction process, the quality of the concrete directly affects the quality of the engineering, so the detection of the concrete strength is particularly important. At present, standard concrete test blocks are commonly used for testing the compressive strength of concrete in civil engineering experiments, the compressive strength test moulds of the concrete in China all adopt cube test moulds, the most used mould is a non-detachable hollow cube mould, the material is plastic, and the bottom of the mould is provided with a small hole. After the test block is formed, the mold is usually knocked back and knocked or demolded by using an air pump through a small hole at the bottom of the mold. In the experiment process at ordinary times, sometimes the concrete blocks the small holes at the bottom of the mould, and sometimes the test block and the mould are damaged due to the fact that the mould is knocked. In addition, the test mold is not detachable, so that a large space is occupied.

Disclosure of Invention

In order to overcome the defects of the existing mold, the utility model aims to provide a detachable concrete test block mold based on a mortise and tenon structure, which can be easily detached and demolded, avoids the test block and the mold from being damaged in the demolding process, and has the advantages of simple structure, space saving, convenience in use and strong practicability.

In order to achieve the purpose, the utility model adopts the technical scheme that:

the utility model provides a can dismantle concrete test block mould based on mortise-tenon joint structure, includes

bottom plate

1, 1 top of bottom plate can be dismantled respectively and be connected with first template 2, second template 3, third template 4 and fourth template 5 to constitute the box structure, in the box structure and can dismantle between third template 4 and the fourth template 5 and be connected with division board 6.

And a limiting groove 7 is formed in the middle of the bottom plate 1.

The two sides of the first template 2, the second template 3, the third template 4 and the fourth template 5 are respectively provided with a dovetail joint 8 and are connected in a two-to-two mortise-tenon mode through the dovetail joints 8.

The first template 2 and the second template 3 have the same structure size, and the third template 4 and the fourth template 5 have the same structure size.

And the inner side walls of the third template 4 and the fourth template 5 are respectively provided with a limiting concave clamping groove 9, and an isolating plate 6 is inserted in the limiting concave clamping groove 9.

The number of the isolating plates 6 and the limiting concave clamping grooves 9 can be correspondingly increased and decreased.

The utility model has the beneficial effects that:

the utility model relates to a detachable concrete test block mould based on a mortise and tenon structure.A bottom plate 1 is provided with a limiting groove 7, a first template 2, a second template 3, a third template 4 and a fourth template 5 are connected in a two-to-two mortise and tenon mode through dovetail joints 8, and a partition plate 6 is inserted into a limiting concave clamping groove 9; the whole structure can be flexibly disassembled and assembled, so that the test block in the mold can be conveniently demolded, the problems that the traditional mold cannot be disassembled and is difficult to demold are solved, and the test block and the mold are prevented from being damaged in the demolding process; in addition, the dovetail tenon in the tenon-and-mortise structure is utilized, when the dovetail tenon is assembled together, the effect of stable structure of the die can be achieved, and when the dovetail tenon is disassembled, the storage space can be saved.

Drawings

FIG. 1 is a schematic structural diagram of the present invention.

Fig. 2 is an assembly and disassembly schematic view of the present invention.

FIG. 3 is a schematic view of the dovetail 8 of the present invention.

In the figure: 1. a base plate; 2. a first template; 3. a second template; 4. a third template; 5. a fourth template; 6. a separator plate; 7. a limiting groove; 8. dovetail joints; 9. and limiting concave clamping grooves.

Detailed Description

The utility model will be further explained with reference to the drawings.

Referring to fig. 1 to 3, a can dismantle concrete test block mould based on mortise-tenon joint structure, includes

bottom plate

The middle of the bottom plate 1 is provided with a limiting groove 7, and the first template 2, the second template 3, the third template 4 and the fourth template 5 are embedded in the limiting groove 7.

The working principle of the utility model is as follows:

before the concrete test block is poured, the die is assembled firstly, and the assembling process is as follows: firstly, respectively connecting a first template 2, a third template 4, a second template 3 and a fourth template 5 through dovetails 8 on the first template, the third template and the fourth template; then the whole body is completely embedded into the middle limiting groove 7 of the bottom plate 1; and finally, inserting the isolation plate 6 into the limiting concave clamping grooves 9 on the inner side walls of the third template 4 and the fourth template 5 to finish the assembly of the die.

After the test block is molded, when the mold is required to be demolded, the mold is firstly disassembled, and the disassembling process is as follows: firstly, disassembling the bottom plate 1; then the isolation plate 6 is pulled out from the limiting concave clamping grooves 9 of the third template 4 and the fourth template 5, and then the concrete test block can be taken out; finally, the first template 2, the third template 4, the second template 3 and the fourth template 5 are sequentially disassembled; when the mould is not used, the mould can be disassembled, and the mould does not occupy space.
