Reinforcing method for improving anti-seismic property of masonry wall
The invention discloses a reinforcing method for improving anti-seismic property of a masonry wall, and relates to the technical field of building construction. The reinforcing method comprises the following steps that a component A and a component B with the same volume are prepared; the surface of the masonry wall is pretreated, and loose materials on the surface are removed; dust treatment is conducted on the surface of the masonry wall; and the component A and the component B are mixed and sprayed, so that the mixed material formed by mixing the component A and the component B is uniformlysprayed on the surface of the masonry wall to reach a certain thickness. A polyurethane or polyurea elastomer is formed by mixing and reacting the component A and the component B according to the volume ratio of 1: 1, the component A is an isocyanate component solution, and the component B is a hydroxyl compound component solution or an amino compound component solution. Spraying operation can beconducted through a pneumatic spray gun, and after spraying is completed, surface drying of the polyurethane or polyurea elastomer can be achieved within several minutes, complete curing is achievedafter 24 hours, and the phenomenon sagging is not caused.
本发明公开一种提高砌体墙抗震性能的加固方法，涉及建筑施工技术领域，包括如下步骤：准备等体积的A组份和B组份；对砌体墙表面进行预处理，去除表面发生松动的材料；对砌体墙表面进行灰尘处理；对A组份和B组份进行混合喷涂，使A组份和B组份混合后的混合材料均匀喷涂在砌体墙表面，并达一定厚度。所用聚氨酯或聚脲弹性体为A组份和B组份按体积1：1混合反应而成，A组份为异氰酸酯组份溶液，B组份为羟基化合物组份溶液或氨基化合物组份溶液。其可通过气动喷枪进行喷涂作业，而在喷涂结束后，聚氨酯或聚脲弹性体在数分钟内即可达到表干，24小时后完全固化，且不会出现流挂现象。
