For realizing above-mentioned purpose, plan to adopt such concrete test block maintenance interval isolating device, including the maintenance frame, the maintenance frame includes that two at least samples along vertical distribution support the backplate, the backplate is supported to the sample sets up along the level, the upper end that the backplate was supported to the sample has two vertical parting beads of parallel arrangement, it puts the test piece district to set gradually the test piece position between two vertical parting beads, and two adjacent test pieces are put and are hung through the lifting rope and be equipped with the isolation ball between the position, the distance between the backplate is supported to the sample of isolation ball distance below is less than the height of test piece, the lifting rope top is fixed in on the sample support the backplate of top.
In the isolating device, a reset ball with a weight larger than that of the isolating ball is fixed above the isolating ball on the lifting rope, the distance between the reset ball and a sample maintenance plate below the reset ball is larger than the height of the test piece, the fixed point at the top of the lifting rope is positioned above the two test piece placing positions and is shifted towards the inlet direction of the test piece, the shifting distance is determined according to the actual situation, under the condition that other conditions are not changed, if the weight of the reset ball is larger than that of the isolating ball, the shifting distance can be smaller, otherwise, the shifting distance is larger, when the test piece is placed, the previous test piece passes through the isolating ball in the placing process, the isolating ball passes through the upper part of the test piece and is separated from the test piece under the action of the reset ball, namely, the transverse traction force of the reset ball to the isolating ball through the lifting rope is larger than the transverse friction force of the test piece to the isolating ball when the isolating ball is above the test piece, so, when the next test piece is put in, the isolation ball clamp is arranged between the two test pieces, the reset ball is smaller than the sum of the friction force of the test pieces on the two sides of the reset ball to the isolation ball and the dead weight of the isolation ball through the lifting rope, so that after the two test pieces are all put in, the isolation ball can be always positioned between the two test pieces to play an isolation role, and the test pieces can not slide out due to the traction of the lifting rope.
In the isolation device, the distance between the two longitudinal isolation strips is 1-5cm greater than the width of the test piece.
The use method of the isolating device comprises the following steps: test piece to test piece position of putting is put into in proper order to test piece entry direction on the backplate is supported to the sample, the in-process that previous test piece was put into is through keeping apart the ball, keep apart the ball through the test piece top and break away from the test piece under the effect of ball that resets, when next test piece was put into, keep apart the ball clamp and locate between two test pieces, the ball that resets is less than the frictional force and the isolation ball dead weight sum of the test piece of ball both sides to keeping apart to the vertical traction force of ball through the lifting rope, keep apart the ball and can be located all the time and play the isolation effect between two test pieces, put into the test piece according to above-mentioned method in proper order, separate two adjacent test pieces by.
Compared with the prior art, the utility model discloses at the in-process of putting into the test block in proper order, the isolation ball can press from both sides by oneself and locate between two adjacent test blocks, can not be detained at the test block top, and it is very simple to use, can avoid the test block that the human reason caused to stack the confusion, make things convenient for personnel to put the test block, avoid closely laminating between test block and test block, make each face of test block receive even humiture maintenance, guarantee standard maintenance test block intensity can reflect concrete works entity quality.
