Embodiment 1

[0032] A steel bar weight deviation detector, see Figure 1 to Figure 6 , including a base 1, a weighing mechanism is installed on the base 1, and a diameter detection unit 6 is slidably installed on the base 1 at the same time, the weighing mechanism includes an elastic base 2, a driving steel support unit 3 installed on the elastic base 2, and a moving steel support unit 4 and the fixed steel bar support unit, the driving steel bar support unit 3, the mobile steel bar support unit 4 and the fixed steel bar support unit are provided with through holes for steel bar support in the same shape and position, and the mobile steel bar support unit 4 is provided with a mobile pair connection between the elastic base 2, The number of through holes is 5, distributed in a circular array. When testing, select five steel bars and insert them into each corresponding through hole in turn, and then adjust the relative positions of the driving steel bar support unit 3, the moving steel bar s...

Embodiment 2

[0041]In this embodiment, the principle is the same as in Embodiment 1, the specific difference is that a rocker 16-type bracket is also provided on the outside of the fixed steel bar support unit, and a length non-contact detection device 13 is provided on the rocker 16-type bracket to measure the steel bar Stretch out the distance of the fixed steel support unit, the rocker 16 type support includes the stepped telescopic tube 15 at the bottom and the rocking bar 16 installed on the end of the telescopic tube, the telescopic tube is provided with a scale to calculate the observed stretching length. During the working process, a detection space is formed between the length non-contact detection device 13 on the rocker 16 type support and the stepped telescopic cylinder 15, which can detect the length of each protruding steel bar one by one. At the same time, if the steel bar protrudes too long , the telescopic tube can be stretched, and the working stretching and shrinking prin...

Abstract

The invention relates to the field of building material detection equipment, in particular to a steel bar weight deviation detector. The problems that in the prior art, a steel bar weight deviation detection mode is simple and single in pertinence are solved. The device comprises a base, a weighing mechanism is installed on the base, meanwhile, a diameter detection unit is installed on the base in a sliding mode, the weighing mechanism comprises an elastic base, a driving steel bar supporting unit, a movable steel bar supporting unit and a fixed steel bar supporting unit, and the driving steel bar supporting unit, the movable steel bar supporting unit and the fixed steel bar supporting unit are installed on the elastic base. The movable steel bar supporting unit and the fixed steel bar supporting unit are provided with through holes which are consistent in shape and position and used for supporting steel bars, the movable steel bar supporting unit is connected with the elastic base through a movable pair, the number of the through holes is five, and the through holes are distributed in a circumferential array shape. The device has the advantages that multiple indexes such as the weight, the thickness mixing degree and the bending degree of a sample can be measured at the same time, and the test piece is convenient to mount and dismount.

Description

technical field [0001] The invention relates to the field of building material testing equipment, in particular to a steel bar weight deviation detector. Background technique [0002] Rebar is a common building material. Its testing standards can be attributed to whether the external dimensions are compliant and whether the internal strength is compliant. In the detection of external dimensions, the detection method at this stage is mainly to measure its weight, and then calculate it in combination with the size and density of the national standard, and check whether its weight is within the compliance range. This method is relatively traditional, but it has low technical requirements for workers and is still widely used today. [0003] In the published Chinese patent documents, the patent No. CN201611103125.2 is called a steel bar weight deviation detection instrument, which discloses a device with a calibration disk. At the same time, the device is equipped with a scanni...
