Description

Threaded planting device and forming method thereof

The invention relates to a planting rib device and a molding method thereof, in particular to a threaded planting device and a molding method thereof.

Generally, the process of planting the ribs, that is, the so-called chemical ribbing, mainly uses a drilling tool to drill a suitable number of screw holes at a predetermined position of the reinforced concrete in the concrete building, and then uses a steel brush (or a jet gun). ) Insert the screw hole to remove the impurities in the screw hole, and then fill the screw hole with the medicine. At present, the main component of the agent used for planting tendons is epoxy resin or cement substrate, which is used for reinforcing steel bars after curing.

However, the above-mentioned conventional ribbing method is complicated and laborious in addition to the step of removing the impurities in the screw holes, and if applied to a high temperature and humid climate, combined with the use of sea sand mixed concrete and poor construction quality, etc. Concrete structures are particularly prone to corrosion. When the chloride ion on the surface of the concrete inside the concrete exceeds a certain amount, the planting agent will produce a latent change. When the creeping force reaches a certain level, the protective passivation film on the surface of the steel bar begins to break, and then the steel bar begins to corrode. Swelling causes cracking and caving of the concrete layer.

Referring to Fig. 1, a conventional concrete planting device 1 is applied to a concrete structure 10 which is provided with a positioning screw hole 101 at a position where the concrete planting device 1 is disposed. The concrete planting device 1 comprises an anchor 11, a reinforcing bar 12, and an engaging unit 13.

The engaging unit 13 is disposed at at least one end of the reinforcing bar 12, and the engaging unit 13 includes a screwing portion 131. The reinforcing bar 12 is the screwing portion 131 of the engaging unit 13 and the screw groove portion of the anchor bolt 11. 113 phase screwing.

However, since the concrete planting device 1 must first fix the anchor bolt 11, the reinforcing bar 12 is locked and implanted by the screwing portion 131 of the coupling unit 13, and the installation step to be performed is cumbersome. In addition, since the concrete planting apparatus 1 includes a plurality of elements separated from each other, it is difficult to manufacture once in a single line, thereby limiting manufacturing efficiency. Moreover, in the process, the anchor bolt 11 must be processed to form the screw groove portion 113, and the screw portion 131 of the screw groove portion 113 is required to perform another thread processing operation, thereby causing processing cost. Higher disadvantages.
