Description
Technical Field
The utility model relates to a concrete structure coring tongs is a concrete structure coring tongs suitable for coring method verifies concrete structure intensity and gets core.
Background
With the progress of society, the quality of engineering entities, especially the strength of concrete, is more and more emphasized in the field of civil engineering, and a coring method is the most effective and direct method for verifying the strength of the concrete entities. In the prior art, a core taking method is used for drilling holes by using a water drill, taking out a core sample and then processing the core sample into a standard test piece. In the prior art, when a core sample is taken after a water drill is drilled, concrete near the core sample is firstly chiseled by a machine, and then the core sample is taken out by a hand. The coring method has the defects that the existing concrete structure is damaged, and the final test result is influenced by the damage of the core sample.
Disclosure of Invention
To the above-mentioned defect that exists among the prior art, the utility model provides a simple structure, economy are suitable for, can high-efficiently accomplish to get the core and play certain guard action's concrete structure core pincers to the concrete core appearance.
The utility model discloses a realize through following technical scheme: the utility model provides a concrete structure coring pliers which characterized in that: the steel pipe fitting is characterized by comprising two steel bar members which are in cross movable riveting connection, wherein the front end of each steel bar member is fixedly connected with a semicircular steel pipe fitting, the semicircles of the two steel pipe fittings are arranged oppositely, the rear end of each steel pipe fitting is plugged through a plugging plate, each steel pipe fitting is connected with the front end of each steel bar member through the plugging plate, and a rubber sheet is pasted on the inner side wall of each steel pipe fitting.
The utility model discloses during the use, the steel bar member end is handed to operating personnel, stretches into the drilling with the steel pipe fitting part of the other end in, then utilizes the steel bar member to take out with core appearance activity back and centre gripping in the drilling. The rubber sheet that sets up in the steel pipe fitting is used for increasing the frictional force of steel pipe fitting and core appearance, guarantees the clamping-force between steel pipe fitting and the core appearance to be convenient for take out the core appearance smoothly.
Further, in order to secure the frictional force between the steel pipe and the core sample, it is preferable that the rubber sheet has a thickness of 1 mm.
Further, in order to ensure smooth sampling, the inner diameter of the steel pipe fitting is preferably 10 cm.
The utility model has the advantages that: the utility model discloses a simple and easy lever principle can make things convenient for, swiftly take out the core appearance, can avoid the destruction to existing concrete structure face in the sample process to because the core appearance is protected by the steel pipe fitting in the outside all the time in the sample process, consequently can guarantee the wholeness and the integrality of core appearance in the sample process. The utility model discloses simple structure, processing convenience use flexible operation, convenience, can effectively solve among the prior art concrete structure and get the core difficulty, get the core in-process to existing structural plane destruction, core appearance protection difficulty scheduling problem.

in the figure, the steel bar rod 1, the rivet bolt hole 2, the steel pipe fitting 3, the plugging plate 4, the rubber sheet 5, the rivet bolt 6.
Detailed Description
The invention will now be further described by way of non-limiting examples with reference to the accompanying drawings:
as shown in the attached drawings, the coring clamp for the concrete structure comprises two steel bar rods 1, wherein rivet bolt holes 2 are respectively formed in the two steel bar rods 1, and the two steel bar rods 1 are crossed and then are movably riveted together through the rivet bolt holes 2 by using rivet bolts 6 to form a simple lever. The front end of each steel bar member 1 is fixedly connected with a semicircular steel pipe 3, the semicircles of the two steel pipe 3 are arranged oppositely, the rear end of the steel pipe 3 is sealed by a sealing plate 4, and the steel pipe 3 is connected with the front end of the steel bar member 1 through the sealing plate 4. Preferably, the steel pipe 3 is a thin-walled pipe having an inner diameter of 10 cm. The length of the steel pipe fitting 3 is not less than the length of a sample to be cored. A rubber sheet 5 is adhered to the inner side wall of the steel pipe 3, and the thickness of the rubber sheet 5 is preferably 1 mm. The rubber sheet 5 is preferably adhered along the inner side wall of the steel pipe 3.
The utility model discloses the time, 1 end of reinforcing bar member is handed to operating personnel, stretches into the drilling with 3 parts of steel-pipe fitting of the other end in, then utilizes reinforcing bar member 1 to take out its centre gripping again after with the core appearance centre gripping in the drilling and the activity. The rubber sheet 5 arranged in the steel pipe 3 is used for increasing the friction force between the steel pipe 3 and the core sample, so that the clamping force between the steel pipe 3 and the core sample is ensured, and the core sample is conveniently and smoothly taken out.
The utility model discloses simple structure, processing is convenient, and convenient operation is nimble, can take out core appearance convenient and fast ground, can effectively solve concrete structure among the prior art and get the core difficulty, get the technical problem of core in-process to existing structural plane destruction, core appearance protection difficulty, have very high practicality.
Other parts in this embodiment are the prior art, and are not described herein again.
