Description
Technical Field
The utility model relates to a civil engineering field especially relates to a irritate device of husky method measurement concrete test piece roughness.
Background
In the research of the interface bonding performance of new and old concrete, the roughness treatment needs to be carried out on the repair surface of the existing old concrete so as to ensure the bonding reliability of the repair material and the existing old concrete. The roughness is usually expressed by the average depth of sand filling, namely, standard sand is poured into the roughened surface of the concrete sample until the highest position of the bonding surface (namely the roughened surface) of the concrete sample is flush, then the volume of the used standard sand is measured, and the volume of the standard sand is divided by the sectional area of the bonding surface, so that the average depth of sand filling can be obtained.
In the operation of the prior art, after standard sand is added to the bonding surface of the concrete test piece, a flat plate is used for scraping the bonding surface of the concrete test piece by hand, then the standard sand reserved on the bonding surface of the concrete test piece is guided into a measuring cylinder to measure the volume, and the result obtained by the method has small deviation with the actual existence.
SUMMERY OF THE UTILITY MODEL
Through a great deal of research by technicians, the reasons for the large error of the measurement result are mainly two points: first, slope when the test piece itself is placed leads to standard sand uneven thickness on the test piece, and the second is when the test piece bonding surface strikes off unnecessary standard sand, owing to lack the restraint device of standard, scrapes after, hardly keeps upper surface and peak parallel and level in the horizontal direction, the phenomenon of scraping more or scraping less appears easily.
The utility model provides a irritate husky method and measure device of concrete test piece roughness to solve the above-mentioned technical problem who mentions.
A device for measuring the roughness of a concrete test piece by a sand filling method comprises at least three telescopic rods with adjustable lengths, a funnel fixedly arranged on the telescopic rods, a horizontal retainer fixedly arranged in the funnel and a sand filling mechanism fixedly arranged on the horizontal retainer, wherein the sand filling mechanism comprises a hard frame and a hard cover plate covered on the hard frame, four sections of conductive coatings are arranged at the top of the hard frame, four LED lamps with power supplies are arranged on the upper surface of the hard cover plate, four groups of conductive coating lines are arranged on the hard cover plate, each conductive coating line turns over the edge from the upper surface of the hard cover plate and extends to the lower surface of the hard cover plate, each LED lamp forms a respective series loop through the corresponding conductive coating line and the corresponding conductive coating, and an adjusting bolt is vertically and rotatably arranged in the middle of the horizontal retainer.
Preferably, the telescopic rod comprises a lower rod and an upper rod which is matched with the lower rod in a rotating mode.
Preferably, the horizontal retainer is a cross-shaped retainer, and a level gauge is further arranged on the horizontal retainer.
Preferably, the hard cover plate is a glass plate.
When the device for measuring the roughness of the concrete sample by the sand filling method is used, the measuring device is placed on the experiment table, and the horizontal holder is adjusted to be horizontal by screwing the lower rod of the telescopic rod; inserting a test piece into the hard frame in a matching manner, screwing an adjusting bolt, enabling the adjusting bolt to push the test piece to move upwards so that the highest point of the test piece slightly exceeds the upper surface of the hard frame, covering a hard cover plate on the hard frame, reversely screwing the adjusting bolt, stopping screwing when four LED lamps form respective serial circuits and are all lightened, and enabling the highest point of the test piece to be flush with the upper surface of the hard frame; taking down the hard cover plate, adding standard sand into the hard frame, scraping off redundant standard sand along the upper surface of the hard frame by using the hard cover plate, and cleaning the upper part of the horizontal retainer; and then, a measuring cylinder is placed below the funnel, the standard sand on the test piece is collected in the measuring cylinder through the funnel for measurement, the average depth of sand filling is obtained through calculation, and the measurement precision is greatly increased due to the horizontal placement of the test piece and the scraping mode of the redundant standard sand which is parallel to the highest point and is constrained by the frame.
Furthermore, a level gauge is embedded in the middle of the horizontal retainer, so that the leveling is simple and efficient.
