Background
At present, the concrete wall still adopts a formwork positioning method, two formworks are arranged in parallel, the distance between the two formworks is positioned by an approximate screw rod, and the distance between the formworks is the thickness of the concrete wall. In the installation process, the template needs to be drilled and provided with the screw, and in order to ensure the smooth installation of the template, the diameter of the through hole of the template needs to be larger than the outer diameter of the screw, so that the slurry leakage phenomenon of the through hole of the template can occur in the construction process; meanwhile, after the concrete wall is formed, the screw and the concrete are integrated, the structure cannot be detached, the screw and the concrete can only be remained in the concrete wall, the time spent on sawing the residual screw is increased, time and labor are wasted, and the construction cost is greatly increased.
Disclosure of Invention
The invention aims to solve the technical problem of providing a splayed harness cord screw which is good in sealing performance, reusable, capable of improving construction progress and saving construction cost.
In order to solve the above problems, the specific technical scheme of the invention is as follows: a kind of screw bolt of withdrawing the splayed harness cord, the outer circumference of the screw bolt of harness cord is the external screw thread totally; the outer surface of the middle part of the harness cord screw rod is wrapped with a plasticizing sleeve together, and the plasticizing sleeve and the harness cord screw rod are fused and solidified into a whole; the outer circumference of the plasticizing sleeve is in a circular truncated cone shape, and the diameter of one end of the plasticizing sleeve is larger than that of the other end of the plasticizing sleeve.
The diameter of one end of the plasticizing sleeve is 4mm larger than the outer diameter of the harness cord screw, and the diameter of the other end of the plasticizing sleeve is 2mm larger than the outer diameter of the harness cord screw.
A method for constructing by adopting a splayed harness cord screw comprises the following steps:
1) setting the position of the template at the harness cord screw according to the thickness requirement of the wall body, and measuring the diameter of the specified position of the harness cord screw by using a vernier caliper;
2) drilling holes at corresponding positions of the template, wherein the diameter of the drilled holes is consistent with the measured value of the vernier caliper;
3) setting the large-diameter end of the plasticizing sleeve to be positioned in the through hole of the outer wall template, and setting the small-diameter end of the plasticizing sleeve to be positioned in the through hole of the inner wall template;
4) after the template is positioned, a batten dragon, a scaffold steel pipe, a steel pipe diagonal brace and a shear brace are arranged to support and position the harness cord screw;
5) pouring concrete into the two templates, solidifying to reach a pressure of more than 1.2MPa, and disassembling the steel pipe inclined strut, the shear strut, the scaffold steel pipe and the batten dragon;
6) the inner wall end of the harness cord screw is knocked by adopting hard objects such as hammerheads and the like, and the harness cord screw can move towards the outer wall along the axis direction due to the large diameter of the outer wall, and can be pulled out and reused after being loosened.
The splayed harness cord screw rod has the following advantages by adopting the structure:
1. the plasticizing sleeve is arranged on the outer circumference of the harness cord screw, so that the strength of the harness cord screw is improved;
2. the paint is easy to separate from the wall body, can be fully recycled, and saves the cost;
3. the plasticizing sleeve is in a round table structure and is tightly matched with the aperture of the template, so that the slurry leakage phenomenon is avoided;
4. because the hole matched with the concrete and the plasticizing sleeve is in the shape of a circular truncated cone and the aperture of the outer template is large, the bottom edge of the hole is in a downhill state, and the water seepage situation is avoided.
