Description

TECHNICAL FIELD

[0001] The utility model relates to a kind of building filling wall structure. BACKGROUND

[0002] Building stress includes pressure stress, bending stress, shear stress and composite stress under various stress conditions.Pressure stress is one of the most common stress conditions of wall body.When wall body is subjected to external pressure, corresponding stress response will be generated.This pressure can be the soil pressure above or on the side of building, structural load, etc.Wall body needs to withstand these pressures and ensure the stability and safety of building.When wall body is subjected to bending moment, bending deformation will be generated.This situation is common when wall body is subjected to forces in different directions, such as local load at the intersection of beam and wall, which can cause bending stress of wall.Shear stress refers to the stress generated by wall due to shear force.This situation is common in dynamic load environment such as earthquake, where wall is subjected to horizontal shear force and needs to have sufficient shear strength to ensure the safety of building.In actual building structure, wall often simultaneously withstands the combined action of various forces, such as pressure, bending stress and shear stress, etc.This composite stress condition needs to consider various factors and comprehensively evaluate the strength and stability of wall.Terro-hollow block is a new type of wall material, which is prepared by mixing super-light terro, cement and water in a certain proportion, stirring, injection molding, molding and curing to become a small closed block with large pores and no sand.The bulk density of terro-hollow block is not more than 600 kg / m 3 , which can float on water, and is 1 / 3 of the advantages of clay brick.Terro-hollow block used as wall filling material for seismic frame structure can reduce the weight of building by more than 30%, greatly improve the seismic capacity, greatly reduce the civil engineering investment, greatly improve the labor efficiency of construction workers and reduce the labor intensity.Terro-hollow block has low thermal conductivity, and the heat loss is 10 times smaller than that of aerated concrete block and 6 times smaller than that of clay brick, which has good thermal insulation and insulation performance;At the same time, the moisture content of terro-hollow block is about 50% lower than that of clay hollow brick, the adsorption force is much stronger than that of aerated concrete block, and it is good in acid and alkali resistance.Because it has the above good thermal performance and product diversification, such as different specifications of block, partition wall, roof insulation brick, balcony board, different specifications of light roof board, etc., it is not only labor-saving and material-saving in building use, but also stable and safe in structure, which increases the effective area of building use, and has the advantages of land saving, energy saving and waste utilization.The existing terro-hollow block is mainly built by mortar, which has the problem of poor shear stress resistance, and the mortar joint generated by building affects the thermal insulation effect of wall.
