Description
Technical Field
The utility model relates to a building engineering technical field especially relates to a hang experimental adapter of anti-drawing of nail among prefabricated component of assembly type structure.
Background
Usually, the adapter (also called adapter) of the drawing instrument is generally divided into two types, wherein one type is the adapter for connecting bolts with various specifications, and the other type is the anchor for various anchor rods and steel bars, and the adapter cannot be directly used for the anti-drawing test of round head hanging nails in prefabricated components of assembled buildings.
In the field of fabricated buildings, suspension nails (ground nails) for prefabricated components have a plurality of forms such as ball head ground nails, monocular ground nails, round head suspension nails and the like, one of the main forms is that a thin rod is arranged in the middle, the two ends have larger diameter than the middle part and are round or similar to round, one end is used as a lifting end, or the thin rod is bent, and the bent part is used as the lifting end; the other large hoisting end is flat and provided with an opening, the other end is rod-shaped, and the hoisting nail is mainly used for hoisting and transferring the prefabricated part. In the production of the prefabricated part, the forming die is sleeved at the hoisting end of the round-head hoisting nail and then integrally embedded into concrete, and the concrete is exposed on the upper surface of the forming die. When hoisting, the forming die is removed, the hoisting end of the hoisting nail is exposed, the hoisting tool is adopted to connect the hoisting nail, and then the hoisting tool is connected with a steel cable on a crown block (or a hoisting machine), so that the hoisting operation of the prefabricated part is realized.
In order to ensure the connection reliability of the hanging nail and the prefabricated part, the drawing instrument is generally adopted to perform the anti-drawing test on the hanging nail, and due to the particularity of the structure of the hanging nail, an adapter of the drawing instrument cannot be directly connected with the hanging nail, so that the normal operation of the test is influenced, and the test precision is reduced.
Disclosure of Invention
The utility model aims to solve the technical problem that a provide a hang resistant adapter of pulling out test of nail in being arranged in prefabricated component of assembly type structure, this adapter can directly be arranged in the tensile of hanging the nail in the prefabricated component of building and pull out the test, and simple structure, and convenient to use is swift, effectively improves test efficiency and precision.
For solving the technical problem, the utility model is used for hang among the prefabricated component of assembly type structure that the experimental adapter is pulled out to nail tensile includes bulb anchor, semicircle ring, strengthening rib pole and screw rod, the semicircle ring penetrates the bell mouth of bulb anchor afterbody, the strengthening rib pole is located the both ends of semicircle ring, the screw rod is located perpendicularly placed in the middle strengthening rib pole top surface.
Furthermore, the bulb anchor is provided with a duckbill buckle, the semicircular ring penetrates into the tail conical hole of the bulb anchor through the duckbill buckle, a groove is formed in the position, in the inner cavity structure of the bulb anchor, of the hanging nail in contact force transmission, and the hanging nail is located in the groove.
Furthermore, both ends of the semicircular ring and both ends of the reinforcing rib rod are welded and connected to form a pull ring.
Further, the screw rod is connected with a matched adapter of the drawing instrument through threads, and the axis of the screw rod is coincided with the stress direction of the hanging nail.
Because the utility model is used for hang among the prefabricated component of assembly type structure that the experimental adapter of drawing of resistant of nail has adopted above-mentioned technical scheme, this adapter includes bulb anchor, semicircle ring, strengthening rib pole and screw rod promptly, the semicircle ring embolias the afterbody bell mouth of bulb anchor, be equipped with the recess with the position that hangs the contact power of meeting of nail in the bulb anchor inner chamber structure, the strengthening rib pole is located the both ends of semicircle ring, the screw rod is located perpendicularly between two parties strengthening rib pole top surface. The adapter can be directly used for the anti-pulling test of the hanging nail in the building prefabricated part, and is simple in structure, convenient and fast to use and capable of effectively improving the test efficiency and precision.
