Description
Technical Field
[0001] The utility model relates to the technical field of cement mortar strength detection, in particular to a detachable cement mortar test mould. Background Art
[0002] Cement mortar strength refers to the ability of a hardened specimen of cement mortar to withstand external damage. It is an important physical indicator that reflects the quality of cement and can also serve as a basis for classifying cement strength grades. The mortar test mold used to form the mortar specimen will also have a significant impact on the test results. Existing cement mortar test molds are as follows: the cast iron test mold needs to be manually assembled in advance using a series of tools. During assembly, the side panels of the test mold are very easy to tilt and require manual angle adjustment. During molding, the test mold needs to be fixed to the compaction table in advance. After compaction, it is manually removed and the entire cast iron test mold together with the mortar is moved to a horizontal table to scrape the molding surface. It is then moved to a standard curing box for curing. After 24 hours, it is removed and demolded. During the demolding process, it is necessary to use tools such as hammers to knock on the bottom of the side wall to remove the cement mortar specimen. Finally, the test mold is manually cleaned and assembled for the next use.
[0003] 1. Manual assembly test molds are very prone to skew. Relying solely on visual observation, the angle adjustment is inaccurate and the side panels are very likely to get stuck during assembly.
[0004] Using an integrated plastic test mold, no manual assembly is required. The "ears" on both sides of the plastic test mold are embedded in the slots and fixed. The operation is simple and convenient, and can be quickly recycled, saving manpower and time, and greatly improving work efficiency.
[0005] 2. During the test, the test mold needs to be moved to the compaction table in advance and fixed. After the compaction is completed, it is moved to the table for flattening. After flattening, it is moved to the curing box for curing. The process is extremely cumbersome. The triple cast iron test mold itself is too heavy, and the weight of the mortar in the test mold after the compaction is completed is added. The number of times it is moved back and forth is too many, which greatly tests the physical strength of the test personnel and also poses certain safety hazards.
[0006] The individual plastic test molds are secured with a slot and can be removed and placed on a table after compaction for subsequent work. The individual plastic test molds are lightweight and easy to handle, significantly reducing the workload and physical exertion of test personnel.
[0007] 3. It is difficult to remove the mold after curing is completed. If the isolation agent is not applied before the test, it will be very difficult to remove the mold. Hitting the test mold with a hammer can easily cause the mold to deform and affect subsequent use. It may also damage the mortar specimen and affect the test results.
[0008] By applying an isolation agent to a single plastic test mold or adding a layer of plastic protective film in advance, it is convenient to remove the mortar test piece when demolding. At the same time, leave a hole at the bottom of the plastic test mold and pad it with thin paper. You can also use a small air pump to help demolding, which greatly reduces the probability of damage to the test mold and test piece.
[0009] 4. The mortar that has solidified and hardened on the test mold needs to be manually cleaned and scraped off. Cast iron test molds are very easy to rust and should not be exposed to water. They can only be manually scraped and brushed, which is time-consuming and labor-intensive.
[0010] A single plastic test mold can be directly washed with water. If a protective film has been added before the test, it is only necessary to clean the plastic protective film, let it air dry naturally, and recycle it. It is easy to operate and saves manpower and costs. In view of this, in-depth research was conducted on the above issues, which led to the creation of this case. Utility Model Content
