Reinforced masonry wall structure filled with rammed earth and construction method thereof

Abstract

The invention discloses a reinforced masonry wall structure filled with rammed earth and a construction method thereof. The masonry wall structure is formed by bonding a plurality of hollow blocks with mortar, wherein the hollow blocks are arranged in sequence in the vertical direction. Every two hollow blocks adjacent in the vertical direction are connected in a staggered-seam lap joint mode, cavities of the hollow blocks are aligned one by one, and thus through cavities extending from first hollow blocks to the top hollow blocks are formed; all the through cavities are filled with rammed earth, and thus rammed earth core columns are formed. The construction method includes the steps that firstly, bottom mortar is laid, and the first hollow blocks are stacked on the bottom mortar; secondly, mortar is smeared on the upper surfaces of the first hollow blocks, the second hollow blocks are stacked in a staggered-seam lap joint mode, and the cavities are completely aligned in the vertical direction; thirdly, the cavities of the blocks are filled with mixed raw earth, and filling and ramming are performed at the same time till the 1 / 3-1 / 2 height position of the second hollow blocks is reached; fourthly, the third hollow blocks are built and then filled with raw earth, ramming is performed till the 1 / 3-1 / 2 height position of the third hollow blocks is reached, and the process is performed in this way till the last hollow block is built and the cavities are full of the rammed earth. The anti-shear property and integrality of the masonry wall are guaranteed.

Description

technical field [0001] The invention belongs to the field of building wall structures, and in particular relates to a reinforced inner-filled rammed-earth masonry wall structure and a construction method thereof. Background technique [0002] Concrete small hollow block masonry structure is one of the most widely used structural forms in my country at present. The shear strength of this kind of masonry often depends on the bonding ability between blocks and mortar. Under horizontal earthquake action, this structure Severe damage to the structure is often caused by insufficient horizontal shear resistance and poor integrity. At present, in order to improve the shear resistance and integrity of masonry, measures such as setting up structural columns and ring beams, or adding reinforcement in the cavity of hollow blocks and then pouring concrete are usually used to improve the shear resistance of concrete small hollow block masonry ability and integrity to improve its seismic p...

Problems solved by technology

However, for remote rural areas and vast mountainous areas where important building materials such as cement and steel bars are relatively scarce, due to constraints such as cost and transportation conditions, a large number of farm houses have not adopted the above-mentioned enhancement measures, resulting in a large number of new farm houses due to insufficient shear resistance. There are major security risks
