Description

Technical field:

[0001] The utility model relates to the technical field of building steel performance detection, in particular to a device for steel gauge marking. Background technology:

[0002] Steel is one of the commonly used materials in the construction industry. The elongation of steel directly affects the safety of the building. Therefore, when steel is used in construction, the performance of the elongation of steel must be tested. The first step in testing the elongation of steel is to cut and make steel segment specimens and measure them. The currently used measuring equipment is the steel bar gauge manufactured by Cangzhou Wilt Testing Instrument Co., Ltd. After marking the steel specimen with the steel bar gauge, the specimen is placed on the tensile testing machine and subjected to a tensile test to calculate its elongation.

[0003] When cutting and making steel segments, gas cutting or other methods are usually used for cutting, and there will be slight twisting and deformation of the steel after cutting. When it is placed in the sample slot of the rebar gauge, since the rebar gauge uses a pressing plate to compress the sample, the pressing plate and the test piece are in line contact, and there is a problem of not being pressed tightly. When the striker hammers the sample mark, there is a phenomenon of the test piece rotating, which affects the marking accuracy. Moreover, the pressing plate of the rebar gauge needs to be manually tightened with a bolt to drive the tightening and loosening, which takes a long time and is inefficient.

[0004] In addition, when using a rebar gauge to mark steel specimens, manual lighting is required to observe the accuracy of the marking position, which is labor-intensive. Moreover, the current rebar gauge can only mark one piece of steel at a time, which is inefficient. Utility model content:

[0005] The purpose of the utility model is to provide a device for marking steel gauge lengths, which is conducive to improving marking efficiency.

[0006] The utility model is implemented by the following technical solutions: a device for marking steel gauge lengths, which includes a steel bar gauge body, a specimen mounting platform, a latch-type quick clamp and an auxiliary striker; the specimen mounting platform is an inverted "T"-shaped structure, and the specimen mounting platform is fixed to the base of the steel bar gauge body by screws; two or more positioning grooves are provided on the top surface of the specimen mounting platform along the length direction, one of the positioning grooves is placed directly below the striker of the steel bar gauge body, and the striker is fixed to the auxiliary striker corresponding to the other positioning grooves through a connecting rod; a group of the latch-type quick clamps are respectively fixed on the top surfaces of both ends of the specimen mounting platform, and the lock seat and the hook seat of the latch-type quick clamp are respectively placed on the top surfaces of both sides of the specimen mounting platform, and the pull bolt between the lock seat and the hook seat is a steel wire rope.

[0007] Furthermore, it comprises two positioning grooves, and a steel ruler is fixed on the top surface of the specimen mounting platform between the two positioning grooves.

[0008] Furthermore, an LED spotlight is fixedly installed behind the striker of the steel bar gauge body.

[0009] Furthermore, shock-absorbing pads are fixed on the four corners of the bottom surface of the steel bar gauge body.

[0010] The advantages of the utility model are as follows: the latch-type quick clamp can quickly clamp two steel bar specimens through the steel strand, and compared with the existing pressing method of the sample by the pressing plate, the application of external force to compress the steel bar sample is beneficial to increase the contact area with the steel bar sample, and the steel bar sample can be pressed tighter to ensure the accuracy of the gauge marking; during the operation of the steel bar gauge instrument body, the gauge marking of the two steel bar specimens can be carried out at the same time by the striker and the auxiliary striker, which effectively improves the marking efficiency.
