Description

Technical Field

[0001] The utility model relates to the technical field of pull-out resistance detection devices, in particular to a pull-out resistance detection device for embedded hanging nails. Background Art

[0002] Pull-out resistance refers to the force that pulls the anchor rod out from the anchor point.

[0003] With the vigorous development of prefabricated buildings, pre-embedded hanging nails in prefabricated components are an important guarantee for ensuring the safety of concrete prefabricated parts during production and transportation. Pre-embedded hanging nails transfer the load to the concrete through round feet, so that a higher allowable load can be obtained with relatively short hanging nails. Even when used in thin walls, the load can be effectively transferred to the concrete and steel bars. Prefabricated components need to be lifted and transported by crane during production and transportation. The pull-out force of the pre-embedded hanging nails in the concrete is particularly important. However, the existing instruments and equipment cannot directly complete the pull-out force test of the embedded hanging nails, resulting in inaccurate pull-out force test data, which in turn affects the strength design and actual use of the hanging nails. Utility Model Content

[0004] In view of this, the utility model provides a pre-embedded hanging nail anti-pull-out force detection device, which can realize the direct detection of the pre-embedded hanging nail anti-pull-out force detection through the detection component, so as to obtain accurate pull-out force value, facilitate the subsequent strength design of the hanging nail, and ensure that the service life and strength of the hanging nail meet the design requirements.

[0005] In order to solve the above technical problems, the utility model provides a pre-embedded hanging nail anti-pull-out force detection device, including a base arranged on a fixed frame, the fixed frame is fixed on the ground by an expansion wire, a through groove is opened on the base, a through jack is arranged above the through groove and on the base, a hook for pulling out the lifting ring of the hanging nail is arranged at the bottom of the through jack, and a detection component for detecting the pull-out force of the hanging nail is arranged on the base.

A pressure sensor is arranged at the lower part of the support column. The pressure sensor arranged on the axis of the hook can accurately detect the pulling force of the top rod of the threading jack on the hanging nail, and the detection result is more accurate.

By pressing the pressure arm, the pull rod of the through-hole jack can be pulled upward with the help of the lever principle, thereby realizing the pulling operation of the lifting ring of the hanging nail hung on the hook at the lower part of the pull rod. At the same time, in the process of the pull rod moving upward, an upward pressure can be applied to the pressure sensor, thereby facilitating the direct acquisition of the magnitude of the pull-out resistance.

[0008] The vertical portion of the fixing frame is welded on the outer side wall of the base.

[0009] A display for displaying the readings of the pressure sensor is provided on the outer side wall of the horizontal part of the fixing frame. The display is electrically connected to the pressure sensor. Through the electrical connection between the display and the pressure sensor, the pressure sensor can transmit the received pressure information to the display.
