Abstract

The invention relates to a concrete test block curing device and in particular relates to a concrete test block loading and curing device. The device comprises concrete test blocks and a loading rack, wherein the loading rack comprises a bottom plate, a top plate and middle separators; four upwards vertical screw rods are symmetrically fixed at four corners of the bottom plate; the four screw rods sequentially penetrate through round holes in the middle separator and the top plate; the concrete test blocks are respectively arranged between the bottom plate and the middle separators, between the adjacent middle separators and between the middle separators and the top plate; meshed grooves which transversely and longitudinally penetrate through one another are respectively formed in the contact surfaces of the bottom plate, the top plate, the middle separators and the concrete test blocks; the area of each meshed groove is larger than the contact surface of each concrete test block; and springs and nuts are respectively arranged on the exposed top plate sections of the four screw rods in a sleeving manner, and pressure is applied downwards by screwing the nuts, so that the top plate, the middle separators, the bottom plate and the concrete test blocks among the three are fastened into a whole. The device is simple in structure and convenient to load, the test blocks are full to cure and convenient to detach, and the device is applied for simulating the curing test of the concrete under the load effect.

Description

technical field [0001] The invention relates to a concrete test block maintenance device, in particular to a concrete test block loading maintenance device. Background technique [0002] At present, for the concrete cube test blocks, the curing is carried out under no load state, and the relevant tests of the concrete test blocks are carried out after curing to a certain age. In actual engineering, concrete often begins to bear loads at an early age, that is, concrete is subjected to force during the curing stage. Therefore, the curing of concrete test blocks under no-load state cannot truly reflect the stress situation of concrete curing stage, which is not conducive to the research of concrete performance. Contents of the invention [0003] The invention aims to provide a small volume, light weight and convenient loading test device for the curing test of the concrete test block under the compressive load, so as to simulate the concrete loading and curing test under rea...
