Description

Technical Field

[0001] This utility model relates to the technical field of building material testing equipment, and more specifically, to building material durability testing equipment. Background Technology

[0002] Building material durability testing equipment is an important component of the building materials technology field. It is mainly used to evaluate the durability performance of building materials under different environmental conditions and usage scenarios. With the increase in global climate change and extreme weather events, as well as people's increasing requirements for building safety and service life, the demand for building material durability testing equipment is increasing day by day.

[0003] Durability testing equipment for building materials is used to conduct durability tests on building materials, allowing construction workers to quickly understand the durability of these materials. However, commercially available durability testing equipment typically involves directly placing the building materials into a protective chamber before testing. This type of equipment lacks a container to hold the materials. Subsequent deterioration and breakage of the materials during testing can cause impurities to contaminate the inner surface of the chamber, making cleaning difficult and potentially damaging the protective chamber, thus affecting its lifespan. Therefore, we propose a new type of durability testing equipment for building materials. Utility Model Content

[0026] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0027] Please see Figures 1-4 This utility model provides a technical solution: a building material durability testing device, including a transparent protective box 1, a rectangular limiting frame 11 fixedly installed on the bottom wall of the transparent protective box 1, the rectangular limiting frame 11 is rectangular ring-shaped, and a storage box 2 is inserted and fitted inside the rectangular limiting frame 11, the size of the storage box 2 is adapted to the size of the rectangular limiting frame 11, and is used for the stable placement of the storage box 2.

[0028] Specifically, the storage box 2 has a storage chamber 20 with its top connected to the outside, which is used for placing building materials. A cylinder 3 is fixedly installed on the top plate of the transparent protective box 1. A vertically arranged rectangular rod 30 is fixedly installed at the end of the telescopic shaft of the cylinder 3. A pressing block 31 is fixedly installed at the bottom of the rectangular rod 30. A sealing plate 32 is slidably connected to the rectangular rod 30. The sealing plate 32 is located inside the transparent protective box 1. A rectangular hole 33 is provided at the center of the sealing plate 32. The rectangular rod 30 passes through the rectangular hole 33 and is slidably connected to it. The sealing plate 32 is located directly above the storage box 2, ensuring that when the cylinder 3 works, it drives the pressing block 31 to move downward, which can perform a compression test on the building materials in the storage box 2. In addition, the sealing plate 32 rests against the top surface of the storage box 2, which can prevent debris from splashing.

[0029] In this embodiment, the lower projection of the sealing plate 32 coincides with the lower projection of the storage box 2, and the outer diameter of the lower pressure block 31 is larger than the outer diameter of the rectangular hole 33, so that the sealing plate 32 can seal the storage box 2 without the sealing plate 32 slipping off the bottom end of the rectangular rod 30.

[0030] Specifically, two symmetrical electric heating rods 10 are fixedly installed on the top wall of the transparent protective box 1. The electric heating rods 10 are used for heating to conduct heat resistance performance testing. Multiple support legs 12 arranged in a matrix are fixedly installed on the bottom surface of the transparent protective box 1. The support legs 12 are used for support operation.

[0031] Furthermore, the front side of the transparent protective box 1 is hinged with two symmetrical transparent door panels 13. Both the transparent protective box 1 and the transparent door panels 13 are transparent. The storage box 2 and the sealing plate 32 are also made of transparent material, which facilitates observation and operation.

[0032] In addition, a door lock 131 is provided on the transparent door panel 13, and a handle 132 is also provided on the transparent door panel 13.

[0033] It is worth noting that gripping rods 21 are fixedly installed on both the left and right sides of the storage box 2. The cross-section of the gripping rods 21 is arc-shaped, which facilitates the taking and putting away of the storage box 2.

[0034] It is worth noting that a misting pump 4 is installed on one side of the transparent protective box 1. A suction pipe 40 is fixedly installed at the water inlet end of the misting pump 4, and a water mist delivery pipe 41 is fixedly installed at the water outlet end of the misting pump 4. Multiple misting nozzles 42 arranged linearly and at equal intervals are fixedly installed at the bottom of the water mist delivery pipe 41. The misting nozzles 42 are located inside the transparent protective box 1. A water tank 43 is installed on one side of the transparent protective box 1. The suction pipe 40 is inserted into the water tank 43. An addition pipe 44 is fixedly installed on the top surface of the transparent protective box 1. A threaded cap 45 is threadedly connected to the addition pipe 44, which facilitates the use of the misting pump 4 to humidify the inside of the transparent protective box 1, thereby enabling the testing of the moisture resistance of building materials.

[0035] In use, the building material durability testing equipment of this utility model involves placing the building material into the storage box 2, inserting the storage box 2 into the rectangular limiting frame 11, and completing the placement of the building material. Then, the transparent door 13 is closed, and the electric heating rod 10 is connected to an external power source and put into operation. The electric heating rod 10 begins heating, raising the temperature inside the transparent protective box 1, thus testing the high-temperature resistance of the building material. Additionally, the atomizing pump 4 is connected to an external power source and put into operation, delivering water to the atomizing nozzle 42 and spraying it out, thus humidifying the inside of the transparent protective box 1, further testing the moisture resistance of the building material.

[0036] In addition, when the cylinder 3 is activated and put into operation, the telescopic shaft on the cylinder 3 extends and drives the lower pressure block 31 to move downward. During the synchronous downward movement of the rectangular rod 30, the sealing plate 32 can slide downward to abut against the top surface of the storage box 2. As the rectangular rod 30 and the lower pressure block 31 continue to move downward, the lower pressure block 31 abuts against the building materials inside the storage box 2, enabling the building materials to be subjected to a compression test.

[0037] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model.
