Description

Corner hoop tie reinforcement system and construction technology of traditional stone masonry houses

Technical field:

The invention belongs to the technical field of reinforcement of traditional stone houses, and in particular relates to a traditional stone house corner hoop tie reinforcement system and a construction process thereof.

Background technique:

Traditional stone masonry farmhouses refer to farmhouses with stone walls as the main load-bearing components. There are significant regional differences and a long history. The types of stone materials and masonry methods in different regions are different, forming colorful stone masonry features. It is one of the main representative forms of traditional dwellings in my country. Due to its advantages such as easy acquisition of local materials, various forms, and long service life of the structure, it is in line with the traditional Chinese farming root culture, self-sufficiency ideology and lifestyle, and is currently widely used in traditional dwellings in my country. Traditional stone farmhouses have a high protection value due to their unique architectural culture and art and their wide application in the field of village and town buildings.

However, due to the long service time and the influence of external natural conditions, and the construction of farm houses is mostly based on the experience accumulated by local craftsmen, it is relatively random and there are potential safety hazards in the structure. A variety of quality problems have appeared in the building, among which cracking at the junction of the vertical and horizontal walls at the corners of the stone-built farmhouses is the most obvious and common quality problem. The formation of cracks in the vertical and horizontal walls of the corners of stone-built farmhouses not only destroys the overall beauty of the building, seriously affects the living comfort of the farmhouses, but also directly reduces the load-bearing capacity of the walls and affects the safety of the structure. If the cracks in the walls are not controlled , will eventually lead to the destruction of the wall and the collapse of the farmhouse, with disastrous consequences. According to field research, a large number of cracks in the vertical and horizontal walls of the corners of the stone-built farmhouses in service are common, and there is currently a lack of effective and economical and reasonable control measures.

The traditional stone-built farmhouse has a large self-weight, and the farmhouse is obviously affected by the self-weight effect, and the shear stress at the joint of the vertical and horizontal walls at the corner of the farmhouse is relatively large; The connection between the vertical and horizontal walls is inconvenient, resulting in a weak connection between the vertical and horizontal walls. The above reasons have caused the traditional stone masonry farmhouses to suffer from serious cracks in the vertical and horizontal walls at the corners. According to field research, the economic development level of traditional stone-built farmhouse distribution areas is limited, and the level of construction technology is low. How to design a simple, effective and economical reinforcement system is the key to the design and construction of the corner steel hoop reinforcement system. question.
