Destructive detection device for strength of building sample block

Abstract

The invention discloses a destructive detection device for the strength of a building sample block. The left side of the upper part of an equipment rack is fixedly connected with a retainer, a screw rod is arranged below the retainer, and the lower part of the screw rod is connected with the upper part of an output shaft through a synchronous belt; the screw rod is in threaded connection with a threaded sleeve which is fixedly connected with one side of the upper part of a movable rod, the other side of the upper part of the movable rod is fixedly connected with a limiting ring which is sleeved with a guide rod, and the lower end of the movable rod is fixedly connected with a steel chisel; and the lower part of the output shaft is fixedly connected with a gear, the gear is meshed with a rack plate, and the rack plate is fixed on the side wall of a working table. The device simultaneously drives the screw rod and the gear to rotate in the same direction through the output shaft, whereinthe rotating screw rod drives the threaded sleeve and the movable rod to move downwards under the action of the limiting ring so as to drive the steel chisel to move downwards for destruction, the rotating gear drives the working table to move leftward to push a sample block, and the sample block is kept still when the steel chisel is damaged and taken out under the action of a telescopic rod, aspring and a stop lever, thus ensuring the accuracy of an experiment.

Description

technical field [0001] The invention relates to a building detection device, in particular to a destructive detection device for the strength of a building sample block. Background technique [0002] According to the "Construction Quality Acceptance Code for Concrete Structure Engineering" (GB 50204-2002) and "Concrete Strength Inspection and Evaluation Standard" (GBJ107-87), the test pieces used to check the concrete strength of structural members should be placed randomly at the place where the concrete is poured. extract. Sampling and retention of test pieces shall comply with the following regulations: [0003] 1. For every 100 trays of concrete mixed but not exceeding 100 cubic meters with the same mix ratio, the sampling frequency shall not be less than once; [0004] 2. When less than 100 trays of concrete with the same mix ratio are mixed in each working shift, the sampling frequency shall not be less than once; [0005] 3. When a continuous pouring exceeds 1000 c...

Problems solved by technology

[0003] 1. For every 100 trays of concrete mixed but not exceeding 100 cubic meters with the same mix ratio, the sampling frequency shall not be less than once;

[0004] 2. When less than 100 trays of concrete with the same mix ratio are mixed in each working shift, the sampling frequency shall not be less than once;

[0006] 4. Concrete on the same floor and with the same mix ratio shall be sampled no less than once;

[0008] The quality of the sample block directly affects the safety and quality of the project. Therefore, it is very necessary to test the various indicators of the sample block. The strength of the sample block is mostly tested by destructive testing. However, when the existing building sample blocks are tested It does not have the function of feeding and testing at the same time, the maneuverability is not strong, and the measurement accuracy is not high
