Method of strengthening masonry walls

Abstract

The invention discloses a strengthening method for a stone wall body. The strengthening method including preparing pre-buried hook members (2), screws (4), flange plates (5), nuts (7), steel angles (8, 11), expansion bolts (12), zinc-coated wires (14), assembling units of steel plates and meshes (15), structural adhesive and concrete material; then excavating foundation pits on two sides of the stone wall body, pouring a concrete foundation (3) and inserting the pre-buried hook members (2); punching through holes in the stone wall body (1), blowing off dust, allowing the screws (4) to penetrate through the through holes, fixing two ends of each screw (4) by the nuts (7); arranging the assembling units of steel plates and meshes (15) on the stone wall body (1) and fixing by the expansion bolts (12); connecting flange plate holes (16), the hook members (2), binding holes (19) and eyelets (18) by binding through the zinc-coated wires (14), to form a criss-cross zinc-coated wires (14) net; the strengthening of the stone wall body (1) is achieved by jetting fine aggregate concrete (20).

Description

[0001] 1. Technical field [0002] The invention relates to a method for strengthening the walls of stone-built houses by connecting flanges through wall-through screws and connecting steel plate meshes through galvanized steel wires, especially suitable for houses built with irregular stone blocks that were built earlier. It belongs to the technical field of seismic reinforcement. [0003] 2. Background technology [0004] Stone itself has high compressive strength and good durability, and has been a traditional masonry material since ancient times. The houses made of stone masonry are warm in winter and cool in summer and have good living comfort. In mountainous areas such as Tibet and Fujian, stone materials are easier to obtain, and there are many stone houses built in private houses. Large-scale palace buildings and a small number of private houses are built with chiseled and processed stone blocks. This kind of wall reinforcement can adopt regular block masonry structur...

Problems solved by technology

[0007] The purpose of the present invention is to overcome the difficulty of construction by inserting the reinforcement method of inserting the reinforcement through the wall and laying the reinforcement mesh on the outside for the stone wall with irregular shape and size, and the piled wall has no neat and regular gaps. Due to defects such as a large number of holes, a stone wall reinforcement method is designed that uses a wall-penetrating screw rod and an external flange to tie the steel plate mesh assembly. The process is simple and easy, and it can effectively improve the earthquake resistance of the stone building.
