Description

Tenon-and-mortise type stone expansion wall block and combined wall thereof

Technical Field

The utility model relates to a building assembly type wall technical field especially relates to a stone wall piece is expanded to tenon fourth of twelve earthly branches formula and combination wall thereof.

Background

"Qin brick Han tile" is the term of brick and tile glorious period, and the appearance of brick can trace back 5000 years ago and has been used as architectural decoration. The Qin generation bricks enjoy the reputation of 'lead bricks', and form a structural system which is complete in structure of 'Qin brick Han tiles' and wood in Western Han dynasty, which is more called 'civil engineering work'.

The 'Qin brick Han tile' is a bright pearl in the Chinese cultural treasury. Therefore, the construction method has the advantages of rich resources, simple manufacture, quick construction, safety and reliability.

However, due to resource limitation, the state has banned taking earth and sintering red bricks, and cement-based building blocks are used instead of red bricks. The application amount of the building blocks is large, the types of the building blocks are more and more, but the problem of micro cracks generated on the surfaces of the building blocks cannot be solved all the time, and the reason is related to the raw materials and the manufacturing process adopted by the building blocks. The raw materials of all the building blocks contain cement and water, and the manufacturing process is that the building blocks are poured into a mould, and the vibration compaction forming is the same as the concrete in terms of drying shrinkage and micro-cracks, so that the micro-cracks are inevitably generated.

The masonry is composed of building blocks and mortar, water cannot be boiled in the masonry process, and the whole wet-making industry can be called. Before building a wall, the building blocks are firstly watered and moistened, and then the building blocks are built by mortar with good stability and workability. The dry-wet-dry process necessarily increases the number of microcracks and the crack width.

The flatness of the masonry manufactured by the existing method is realized by plastering. In the actual construction process, the flatness of the wall is ensured to be very difficult by the technical level of a technician, and a large amount of criss-cross mortar reticulate patterns are easy to appear on the surface of the built wall.

The existing building blocks are required to be mixed with a large amount of mortar for building on site, the efficiency is low, the site environment is polluted, and the requirements of the assembled building which is vigorously advocated by the nation can not be met.

The existing brick and different building blocks are both brittle materials, and cement mortar is also a brittle material. The masonry structure has obvious brittleness characteristic, poor ductility and lower mechanical indexes. Therefore, the national standard requires that the wall body and the main structure must adopt a method of tie bars, which is labor-consuming, time-consuming and material-consuming, and the damage of the wall body causes the damage of the main structure at the same time, so that the damage is not paid. Flexible connections or connection practices in which the body structure and the wall are disconnected from each other, which are advantageous for earthquake resistance, cannot be achieved.
