Description
Technical Field
The utility model belongs to the technical field of face frontier defense and specifically relates to a do pull rod mounting who faces frontier defense with fixed scaffold pipe of concrete shear force wall.
Background
In high-rise building engineering, the frontier defense is very important, and is an important barrier for ensuring the operation safety in a personnel building. The conventional methods include two methods, namely, firstly, an operator drives the shaped plastic scaffold pipe fixing clamp into the shear wall by using an expansion screw and then places a steel pipe. And secondly, fixing the steel pipe at the end part of the shear wall by using a fastener.
The prior art has the following defects:
1) the expansion bolts are easy to directly hit on the main body steel bars during construction, and damage is caused to the main body.
2) When the expansion bolt is used for a long time, the expansion bolt falls off, the scaffold tube is not fixed stably, great potential safety hazards exist, and the expansion bolt is arranged to be modified by personnel and consumes time and labor.
3) The steel pipe is fixed at the end part of the shear wall by utilizing the extrusion force at the two ends of the fastener, so that the steel pipe is unstable in fixation and easy to fall off. And at least two persons are needed to cooperate when fixing.
4) The prior art is complicated to install and dismantle.
Disclosure of Invention
The utility model provides a solve above-mentioned problem, provide a simple structure, dismantle convenient, use firm utilize concrete shear force wall to drawing the screw and fix the handle pipe and do the pull rod mounting who faces the limit protection.
The utility model discloses the technical scheme who takes:
the utility model provides a do pull rod mounting that faces limit protection with concrete shear force wall fixed scaffold pipe, includes split screw and draw-bar nut, and split screw one end is the screw rod, has seted up the screw thread on the screw rod, and the other end is crooked into half circular arc, forms scaffold pipe fixing clip, and draw-bar nut is "mountain" font, and draw-bar nut's middle part is the nut inside groove, sets up the screw thread that corresponds with the screw rod on the internal diameter of nut inside groove, and in the screw rod was connected to the nut inside groove, the both sides of draw-bar nut inside groove were nut square timber fixed slot, and the both sides lateral wall of draw-bar nut is nut square timber fixed cell wall.
The semi-circular arc-shaped inner diameter of the scaffold tube fixing clamp is 55mm, and the outer diameter of the scaffold tube fixing clamp is 65 mm.
The screw rod is a cast iron pull rod with the diameter of 20mm and the length of 400 mm.
The nut square wood fixing groove is a cast iron groove which is 500mm long and 10mm thick.
The utility model has the advantages that: the utility model adopts the counter-pulling screw rod and the pull rod nut counter-pulling fastening principle on the two sides of the shear wall, the plate is cut in operation, the operation efficiency is improved, the maintenance is simple and convenient, the problem that the main reinforcement of the structure is damaged when the expansion bolt is installed is avoided, and the high-altitude operation is not needed by applying the utility model, thereby being beneficial to the safety management; expansion bolts do not need to be installed, potential safety hazards caused by temporary power utilization are avoided, and temporary power utilization safety management is facilitated. The potential safety hazard problem that personnel's shortage leads to the untimely formation of face limit scaffold pipe reinforcement because of consolidating the difficulty is reduced.
