Heat-insulating double-layered wall for buildings

Abstract

The invention discloses a heat-insulating double-layered wall for buildings, which consists of hollow building blocks, heat-insulating boards, reinforcing steel bars and concrete. The double-layered wall has the following characteristics that: the longitudinal reinforcing steel bars are arranged in top building block slab grooves of the double-layered wall, and are tied together by the latitudinal reinforcing steel bars. The heat-insulating double-layered wall is built with the hollow building blocks, the hollow building block comprises a top slab, two supporting legs and a reinforcing rib, and the top slab is provided with two or more ribs, between which a top slab groove is formed. When the heat-insulating double-layered wall is built, the longitudinal reinforcing steel bars are arranged in the top building block slab grooves of the wall body every 3 to 5 bricks, and are tied together by the latitudinal reinforcing steel bars, the concrete is poured in the top building block slab grooves to form reinforced concrete belts, and the inner and the outer wall bodies are connected, so that the heat-insulating double-layered wall is formed. The heat-insulating boards can be inserted in the hollow building blocks and between the two wall bodies in order to meet the requirement on the thermal performance of the energy-saving wall body. because the hollow building block is a light building block, the overall load of the building can be effectively reduced, and the cost of the building can be reduced.

Description

Technical field: [0001] The invention relates to the field of building construction, in particular to a thermal insulation double-leaf wall for a building. Background technique: [0002] Since the production of traditional wall materials consumes a lot of land resources and energy, and has caused serious harm to our country's environment, all provinces and cities across the country are vigorously developing and promoting new non-sintered walls that save land, energy and waste. Building blocks of various materials have been developed and promoted one after another. In recent years, small concrete hollow blocks and air-entrained concrete blocks have been widely used in the field of construction. The patent with the publication number CN2915992Y discloses a hollow block for construction. The hollow block consists of a top plate and two supporting legs. A reinforcing rib is arranged between the two supporting legs. Two or more convex ribs are arranged on the top plate. The blo...

Problems solved by technology

However, the heat insulation performance of the block cannot meet the thermal performance requirements of the energy-saving wall. When it is used as the exterior wall of a building, it is necessary to install an insulation layer inside and outside the hollow block wall. The construction is cumbersome, and the maintenance cost of the inner and outer insulation layers of the wall is high. poor fire resistance
