At present, methods such as bar-planting anchoring, expansion bolts and embedded rods are mainly adopted for connecting the anchoring device and the top plate of the concrete structure, but the methods all need to weld the anchoring device with exposed ends of the anchoring steel bars, the expansion bolts or the embedded rods, welding or anchoring can be carried out only by lifting welding equipment to the lower part of the top plate, and the operation is time-consuming and labor-consuming and cannot be guaranteed in the aspect of safety.
SUMMERY OF THE UTILITY MODEL
An object of the utility model is to provide a combined type screw anchor built-in fitting device realizes the high-speed joint of anchor device and concrete structure roof.
In order to achieve the purpose, the utility model provides a combined type thread anchoring embedded part device, which comprises a positioning backing plate, a straight thread sleeve, an anchoring rib, a structural support, a reinforcing bolt and a bolt accommodating box; a circular through hole and a rectangular through hole are formed in the positioning base plate; the width of the rectangular through hole is larger than the diameter of the reinforcing bolt body and smaller than the diameter of the head of the reinforcing bolt; the straight thread sleeve is welded in the circular through hole; the anchoring rib is L-shaped, the first end of the anchoring rib is inserted into the straight thread sleeve, the bent part of the anchoring rib is welded in the structural support, and the second end of the anchoring rib is positioned outside the structural support; the reinforcing bolt is placed in the bolt accommodating box, and the end part of the reinforcing bolt faces the rectangular through hole; the bolt accommodating box is fixed on the rectangular through hole and is positioned at the same side of the positioning base plate with the straight thread sleeve.
Furthermore, the positioning backing plate and the structural support are square; the number of the circular through holes is four, and the circular through holes are positioned in the right angle of the positioning base plate; the number of the anchoring ribs is four, and the four anchoring ribs are welded in the right angle of the structural support respectively.
Further, the positioning base plate is a steel plate; the anchoring ribs are deformed steel bars or round steel bars; the structural support is formed by welding equal-edge angle steels; the bolt accommodating box is formed by welding iron plates and is welded on the rectangular through hole.
The utility model has the advantages that:
fixing the combined type thread anchoring embedded part device in a concrete roof template according to a design position, enabling a positioning base plate to be tightly attached to the concrete roof template, pouring the concrete roof, exposing the positioning base plate after the template is removed, and enabling a thread anchor rod of the anchoring device to penetrate through a circular through hole of the positioning base plate and be in threaded connection with a straight thread sleeve. Because the positioning base plate faces downwards, the reinforcing bolt extends out of the rectangular through hole under the action of gravity, and is connected with the anchoring device with the preset threaded hole, so that the connecting strength is increased. By last knowing, use above-mentioned combined type screw thread anchor built-in fitting device, anchor muscle and structural support are more firm with being connected of concrete structure roof, and after the form removal, concrete structure roof surfacing does not have the arch, adopts threaded connection with anchor device, compares with traditional welding mode, and is more convenient fast.
