Problems solved by technology

However, in the specific maintenance process, there is a problem that after the formwork is removed, especially in the early removal process, there will be cracks in the wall; and if it is maintained with the formwork, it will cause the problem of insufficient maintenance. And the maintenance cost is high, and the engineering quality is poor

Abstract

The invention discloses a multifunctional nut applied to a concrete wall. The multifunctional nut comprises a water stop screw, a conical nut part, a first screw part fixedly connected with the conical nut part, a second screw part and a screw part mutually connected with the second screw part, wherein the conical nut part comprises a special-shaped nut, the special-shaped nut is gradually thickened from one end to the other end of the special-shaped nut, and the thinner end of the special-shaped nut is fixedly connected to the first screw part; the first screw part comprises a first screw with a first internal thread, and the outer diameter of the first screw is equal to the inner diameter of the thinner end of the special-shaped nut; the second screw part comprises a second screw with asecond external thread, and one end of the second screw is in threaded connection with the first screw; and the screw part comprises a third screw, and a second internal thread is arranged on the third screw. The multifunctional nut is high in practicability and functionality and can be widely applied to the technical field of building construction equipment.

Description

technical field [0001] The invention relates to the field of building construction equipment, specifically a multifunctional nut used on concrete walls, more specifically, for the purpose of making the gap between the formwork and the concrete wall reachable without removing the formwork after the concrete wall is poured. , It can also protect the concrete from the water in the gap. Background technique [0002] In the prior art, after the building construction is completed, the formwork is generally removed, so as to achieve the purpose of water ingress and maintenance of the concrete wall. However, in the specific maintenance process, there is a problem that after the formwork is removed, especially in the early removal process, there will be cracks in the wall; and if it is maintained with the mold, it will cause the problem of insufficient maintenance. Moreover, the maintenance cost is high and the project quality is poor. [0003] Therefore, a kind of device that can ...
