Description

Tibetan rubble wall body

Technical Field

The utility model belongs to civil engineering masonry structure field especially relates to a hidden rubble wall body.

Background

The Tibetan rubble wall has the advantages of good durability, easy material acquisition, good heat preservation and the like, is widely applied by Tibetan people, and due to the limitation of economic and geographical conditions, a lot of Tibetan residences adopt the rubble wall. Because the masonry stone used for the rubble wall is irregular, the integrity of the rubble wall cannot be increased by adopting a traditional method of adding reinforcing steel bars into the rubble wall, and the yellow mud used as a bonding material has low strength and poor bonding effect, so that the rubble wall is easy to collapse under the action of an earthquake. The Fiber Reinforced Plastic (FRP) has the advantages of high tensile strength, light weight, corrosion resistance and the like, and the FRP grid woven by the Fiber reinforced plastic has the characteristics of light weight, softness and easy cutting, is suitable for a rubble wall body, and plays a role of tying ribs in a rubble masonry. The cement-based composite material (ECC) has the advantages of excellent mechanical property, obvious ductility characteristic, microcrack, self-healing, erosion resistance and the like, and is a novel structural material and very suitable for being used as a bonding material to replace yellow mud for newly-built Tibetan rubble walls. The method improves the mechanical property of the rubble masonry, enables the rubble masonry to become a safe bearing member, is one of the keys for improving the anti-seismic property of the traditional Tibetan dwelling houses and enabling the dwelling houses to meet the requirements of modern life on the premise of protecting the traditional building style.

SUMMERY OF THE UTILITY MODEL

An object of the present invention is to solve at least the above problems and/or disadvantages and to provide at least the advantages which will be described later.

To achieve these objects and other advantages in accordance with the purpose of the invention, there is provided a hidden rubble wall, comprising:
