A device for testing hardness of building materials

Abstract

The invention discloses a construction material hardness detection device, which comprises a base, a support plate, a hardness tester box and a sleeve. The position of the hardness tester box can be adjusted in all directions through the forward and backward sliding of the column and the expansion and contraction of the telescopic rod, and at the same time, the second hydraulic cylinder moves up and down Adjust the height of the hardness tester box to facilitate the adjustment of the hardness testing range. The lifting of the first hydraulic cylinder drives the sleeve up and down, which can adjust the height of the building materials to be tested, which is convenient for the fixed building materials to be placed on the table for hardness testing. The inner first splint is tightened under the push of the lock rod. When the guide wheel on the first splint clamps the rod for hardness testing, the rod can move with the guide wheel, which is convenient for all-round hardness testing of the rod. The first clamping plate fixes the concave plate through the flower-shaped rod and can be used to clamp the plate-shaped object, so the present invention can simultaneously perform hardness testing on rod-shaped objects and plate-shaped objects in building materials, and one object is multi-purpose, which improves the scope of use of the hardness testing device .

Description

technical field [0001] The invention belongs to the technical field of building material equipment, in particular to a building material hardness testing device. Background technique [0002] In the process of building construction, in order to ensure the quality of the building, it is necessary to test the building materials. Among them, the hardness is an important indicator of whether the quality of the building materials meets the standards. Because the building materials include not only floor tiles, tiles and other boards, but also steel Rod-like objects such as rods or water pipes, such as the hardness detection device disclosed by the publication number CN109211677A which is convenient for clamping steel pipes, insert the steel pipes into the sleeve, and use electromagnetic force to fix the steel pipes. Although the fixing effect is good, the electromagnetic force The power needs continuous power support, which wastes resources. In addition, due to the limitation of ...

[0002] In the process of building construction, in order to ensure the quality of the building, it is necessary to test the building materials. Among them, the hardness is an important indicator of whether the quality of the building materials meets the standards. Because the building materials include not only floor tiles, tiles and other boards, but also steel Rod-like objects such as rods or water pipes, such as the hardness detection device disclosed by the publication number CN109211677A which is convenient for clamping steel pipes, insert the steel pipes into the sleeve, and use electromagnetic force to fix the steel pipes. Although the fixing effect is good, the electromagnetic force The power needs continuous power support, which wastes resources. In addition, due to the limitation of the fixing device, the traditional hardness testing device can only perform hardness testing for specific types of materials, and it is difficult to detect various plates and objects in building materials. All-round hardness testing of rod-shaped objects, and the purchase of multiple hardness testing devices will increase construction costs and cause waste of resources. Therefore, for hardness testing of building materials, a device that can test various types is needed to save costs. ,Improve efficiency
