Description

Technical Field

[0001] The utility model relates to the technical field of construction engineering, in particular to a cement slurry test piece mould. Background Art

[0002] Cement paste, as a cement-based material, is a slurry formed by mixing cementitious materials (cement, fly ash, etc.) and water. It is usually used in the fields of construction and engineering, and is also widely studied in the field of scientific research. Usually, when studying cement-based materials, small cubic specimens need to be formed. Since cement-based materials, especially cement mortar and cement paste, have strong fluidity, they need to be placed in a mold for finalization before they solidify. When mixing cement paste with a high water-cement ratio (i.e., the mass of water to the mass of cementitious materials), due to the addition of more water and less cementitious materials, its fluidity is often very large and will flow out from the gap of the mold. At the same time, the existing cement paste molds are mainly divided into two types: one is a steel mold, which has the advantage of being disassembled and easy to demould, but its sealing is limited and the disassembly is more complicated; the other is a plastic mold, which has the advantage of being relatively light and low in cost, but there is a small hole at the bottom for demoulding, and the cement paste will flow out through the small hole, and its demoulding requires the use of an air compressor to assist, which is cumbersome to operate. Therefore, the utility model aims at the deficiencies of the above two molds and designs a cement paste test piece mold which has good sealing performance and can be disassembled. Summary of the invention

[0003] In view of the problems in the above-mentioned prior art, the utility model provides a cement slurry specimen mold, which has the advantages of simple operation and good sealing. Its technical solution is: it includes a base plate and a sleeve, a groove is arranged on the base plate, and the groove is matched and connected with the bottom of the sleeve, hooks are arranged at both ends of the base plate, and a buckle is arranged on the sleeve, and the buckle is matched and connected with the hook.

[0004] As a preferred embodiment, the buckle is composed of an opening and closing control pull ring, a hanging ring, a rivet and a fixed base plate. The fixed base plate is arranged on the outer wall of the sleeve, and the fixed base plate is hinged to the opening and closing control pull ring through rivets. Plug holes are provided on both sides of the opening and closing control pull ring, and the plug holes are clamped with the hanging ring.

[0005] As a preferred solution, the top of the sleeve extends in all directions.

[0006] As a preferred solution, a sealing ring is embedded in the groove of the bottom plate.

[0007] Beneficial effects of the utility model:

[0008] 1. By setting grooves on the bottom plate and installing sealing rings, it can effectively prevent cement paste with high water-cement ratio and strong fluidity from flowing out of the mold joints;

[0009] 2. The mold has a simple composition, is easy to operate, and can be disassembled and reused. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The utility model is further described in detail below based on the accompanying drawings and specific embodiments.

[0019] Example 1

[0020] like Figure 1-4 As shown, a cement slurry specimen mold includes a base plate 1 and a sleeve 3. A groove is arranged on the base plate 1, and the groove is matched and connected with the bottom of the sleeve 3. Hooks 8 are arranged at both ends of the base plate 1, and a buckle is arranged on the sleeve 3, and the buckle is matched and connected with the hook 8.

[0021] like Figure 1 , 2 The buckle shown in , 5 is composed of an opening and closing control pull ring 4, a hanging ring 5, a rivet 6 and a fixed base plate 7. The fixed base plate 7 is arranged on the outer wall of the sleeve 3. The fixed base plate 7 is hinged to the opening and closing control pull ring 4 through the rivet 6. Plug holes are opened on both sides of the opening and closing control pull ring 4, and the plug holes are clamped with the hanging ring 5.

[0022] like Figure 1-4 The top of the sleeve 3 extends in all directions, which is convenient for stacking molds and smoothing the slurry.

[0023] like Figure 6 , 7As shown, a sealing ring 2 is embedded in the groove of the bottom plate 1 to prevent the pure slurry from flowing out from the joint of the mold and increase the sealing performance of the mold.

[0024] The above mold is used as follows:

[0025] Put the sealing ring 2 into the groove of the base plate 1, fix the two hooks 8 on the edges of the left and right base plates 1 with super glue, stick the two fixed base plates 7 on the left and right sides of the sleeve 3 with super glue, hinge the opening and closing control pull ring 4 with the fixed base plate 7 with rivets 6, and snap one end of the hanging ring 5 with the opening and closing control pull ring 4, place the sleeve 3 in the groove of the base plate 1 with the sealing ring 2, and manually control the opening and closing control pull ring 4 on the sleeve wall to buckle the hanging ring 5 with the hook 8 of the base plate 1 to complete the assembly of the mold. After the assembly is completed, the cement slurry can be loaded, followed by tamping, vibrating and smoothing.
