Composite concrete building casing member and plate, and their combining method

Abstract

A kind of box-type structural members and slabs for the combined building without balcony and staircase is disclosed. Said box-type structural member is a pentahedron made of reinforced concrete and has the insulating foam polystyrene board on its external surfaces. Its wall and roof are the prefabricated slabs made of aerated reinforced concrete prepared from powdered coal ash and cement. Its column, beam and ribbed beam are the prefabricated concrete members. Its combining technology includes such steps as arranging said members in a combining foam, coupling anchors, binding, welding, inserting spiral reinforcing bars, and casting concrete.

Description

technical field [0001] The present invention relates to concrete buildings, in particular to composite concrete building box-type components and panels and a combination method thereof. Background technique [0002] With the massive increase of residential construction in our country and the continuous improvement of the degree of construction industrialization, especially with the gradual withdrawal of clay solid bricks from the historical stage, the industrialized prefabricated building system of residential buildings will surely develop and grow. Large slab system, cast-in-place slab system and frame light slab system have many shortcomings, such as high cost of construction, poor integrity, low thermal insulation and sound insulation effect, complex process and large on-site workload, which seriously hinder their survival and development. Foreign box-type building structures are also difficult to popularize and apply due to many reasons such as complex technology, heavy ...

Problems solved by technology

[0002] With the massive increase of residential construction in our country and the continuous improvement of the degree of construction industrialization, especially with the gradual withdrawal of clay solid bricks from the historical stage, the industrialized prefabricated building system of residential buildings will definitely develop and grow. However, the existing assembly in our country Type large slab system, large slab cast-in-place system, and frame light slab system have many disadvantages, such as high cost, poor integrity, low thermal insulation and sound insulation effects, complex process, and heavy on-site operations, which seriously hinder their survival and development.

The foreign box-type building structure is also difficult to popularize and apply due to many reasons such as complex process, heavy self-weight, high cost, and rigid combination.
