Description

Technical Field

[0001] This utility model relates to the field of concrete permeability testing technology, and in particular to a concrete test block permeability testing device. Background Technology

[0002] A concrete permeability tester is used to test the permeability of concrete to water or other media under pressure.

[0003] The concrete permeability tester mainly consists of a frame, molds, a sealing system, a pressurization system, a control system, and a water system. The molds are used to create concrete blocks of the desired shape. After repeated use, the inner wall of the mold is worn down by the concrete, leading to poor sealing and requiring replacement. However, existing molds are all integrally molded, requiring replacement of the entire mold when the interior is worn, resulting in resource waste. Therefore, there is an urgent need to develop a concrete block permeability tester that allows for convenient replacement of worn areas within the mold, saving resources and overcoming the shortcomings of current applications to meet current needs. Utility Model Content

[0004] The purpose of this invention is to provide a concrete test block permeability tester to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A concrete test block permeability tester includes a tester body with six detachably mounted spliced ​​test molds. Each spliced ​​test mold contains six detachably mounted inner modules. The inner modules are arc-shaped, with their outer walls fitting against the inner walls of the spliced ​​test molds. Each inner module has a locking strip fixed to its right side and a locking groove for securing the locking strip on its left side. Each inner module has two detachably mounted fastening bolts that are screwed onto the spliced ​​test molds.

[0007] Preferably, the top of the spliced ​​test mold is provided with multiple threaded holes for tightening bolts.

[0008] Preferably, the inner module is made of 45# steel.

[0009] Preferably, the permeability tester body is fixed with multiple screws, and the lower end of the spliced ​​test mold is provided with multiple through holes for the screws to pass through. Each screw can be detachably installed with a nut.

[0010] The beneficial effects of this utility model are as follows: When using this concrete test block permeability tester, concrete is poured into the inner side of the spliced ​​mold to form the test block. When the inner modules within the spliced ​​mold are worn down by repeated use, the spliced ​​mold is removed from the tester body, the fastening bolts are unscrewed, and then multiple inner modules are removed from the mold. These inner modules are then observed, and severely worn inner modules 203 are replaced with new ones, thus saving resources. In summary, this utility model allows for convenient individual replacement of worn areas within the mold, saving resources. Attached Figure Description

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0019] Specific implementation examples are given below.

[0020] See Figures 1-5In this embodiment of the present invention, a concrete test block permeability tester includes a permeability tester body 1. Six modular test molds 2 are detachably mounted on the permeability tester body 1. Each modular test mold 2 contains six detachably mounted inner modules 203. The inner modules 203 are arc-shaped, and their outer walls are fitted to the inner walls of the modular test molds 2. The inner modules 203 are made of 45# steel, giving them good wear resistance and improving their service life in friction with concrete. Each inner module 203 has a locking strip 206 fixed to its right side and a locking groove 205 for locking the locking strip 206 on its left side. Each inner module 203 has two detachably mounted fastening bolts 204 that are screwed onto the modular test molds 2. The top of the modular test molds 2 has multiple threaded holes 202 for screwing the fastening bolts 204 into it.

[0021] Multiple screws 3 are fixed on the body 1 of the permeability tester. Multiple through holes 201 for the screws 3 to pass through are provided at the lower end of the spliced ​​test mold 2. A nut 4 can be detachably installed on each screw 3. Tightening the nut 4 will press and fix the spliced ​​test mold 2 onto the body 1 of the permeability tester.

[0022] The main body 1 of the anti-permeability instrument is also equipped with a sealing system, a pressurization system, a control system and a water system (same as the prior art, not shown in the figure).

[0023] Working principle: When using this concrete test block permeability tester, concrete is poured into the inner side of the spliced ​​test mold 2. When the inner module 203 inside the spliced ​​test mold 2 is worn by the concrete after repeated use, the spliced ​​test mold 2 is removed from the permeability tester body 1, and the fastening bolts 204 are unscrewed. Then, multiple inner modules 203 are taken out from the spliced ​​test mold 2, and the multiple inner modules 203 are observed. The severely worn inner modules 203 are replaced with new ones to save resources.

[0024] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0025] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
