Method for preventing water from entering core board

Abstract

A method for preventing water from entering a core board is provided. When a core board is used for building a house, on-site installation of the core board comprises the steps of: when the core boardleaves a factory, a water leakage seam in the core board is sealed; when the core board is cut on site, the core board is sealed by a metal plate or temporarily sealed by an adhesive material; when the core board is welded, the adhesive material at the sealing opening is torn, and a possible water inlet position is immediately closed after the welding; and after the core board is mounted and decorated, holes are drilled at the lowest parts of core board components such as columns, beams, floors, balconies and bay windows. Water can be effectively prevented from entering the core board and accumulating, the service life of the core board is prolonged, the heat insulation performance is improved, the building load is reduced, and the safety performance is improved.

Description

technical field [0001] The invention relates to the construction field, in particular to a method for preventing water from entering inside a core board. Background technique [0002] In the prior art, a solid steel plate is usually used as a building base material, and the high-strength performance of steel is used to construct the frame of the house. However, this method usually uses more materials. Although it can ensure the strength of the building when it is used in high-rise buildings, it will bring problems such as heavy weight and waste of materials. In order to solve these problems, some people have proposed to use honeycomb steel instead of solid steel. However, the honeycomb core is continuously formed, there is no gap, it is not easy to weld, and it is easy to produce false welds, or multiple positions of the honeycomb core are not welded. Or produce gaps or voids, etc., resulting in poor overall welding strength and structural stability. [0003] Therefore, th...

Problems solved by technology

When the applicant uses the core board for building buildings, because the inside of the core board is a sandwich layer, such as hollow tubes, gaps are provided between each hollow tube, which is easy to enter water or accumulate water. Once water enters, It will affect the service life of the core board, reduce the thermal insulation performance, increase the building load, and affect safety
