Method for reinforcing row-lock wall through adopting wire entanglement and cement mortar

Abstract

The invention relates to the field of construction engineering, and discloses a method for reinforcing a row-lock wall through adopting a wire entanglement and cement mortar, and the wire entanglement, through-wall pins embedded in the reinforced row-lock wall and a cement mortar protective layer are included. The technical scheme is that the method includes the following steps: placing the through-wall pins in mortar joints between bricks on flat and header bricks as per the actual masonry method of the row-lock wall, fixing the wire entanglement on the wall surface through the pins, and then constructing the cement mortar protective layer on the surface of the wall body. The method remarkably improves the bearing capacity and resistance to vibration of the row-lock wall, and the testing result shows that the horizontal limit bearing capacity of the reinforced row-lock wall body is improved by more than 50% than that of an unreinforced wall body; and meanwhile, the wire entanglement is low in construction cost, the construction technology is simple, templates do not need to be erected, and the method is very suitable for the masonry structure of the row-lock wall, and is particularly suitable for solving the problems of poor structural intensity and limitation of the reinforcing technology due to economical conditions of the existing row-lock walls in villages and towns.

Description

technical field [0001] The invention relates to the field of construction engineering, and relates to a structure strengthening and repairing method for reinforcing an empty bucket wall by using barbed wire cement mortar. Background technique [0002] Empty bucket wall houses are the main structural type of village and town buildings in the middle and lower reaches of the Yangtze River and East China, with a large number and a wide area. In most areas, standard clay bricks are usually used for empty bucket walls, and it is more common to build them with three buckets and one sleep or five buckets and one sleep. Through the investigation, it was found that the mechanical performance and seismic performance of the empty bucket wall houses are worse than those of the solid buildings, and because most of the empty bucket wall houses are built by farmers themselves, there are generally high storey heights, large bays, and imperfect structural measures. The problem is that there ...

AI Technical Summary

Problems solved by technology

Due to the special masonry form of the empty bucket wall, the mechanical performance of the bucket brick position is poor, and the existing various masonry structure reinforcement methods are aimed at solid walls, and the connection and anchoring measures and positions are not suitable for the empty bucket wall structure
