Abstract

The invention relates to a precast net rack sandwich wallboard and a connecting construction method for the same, belonging to the novel building material structure technical field. The precast net rack sandwich wallboard is characterized in that: the precast net rack sandwich wallboard comprises a core plate (1), wherein, a steel wire gauze (2) and a steel wire gauze (9) are respectively arranged on the upper surface and the lower surface of the core plate; the upper steel wire gauze and the lower steel wire gauze are fixedly connected with an inclined dowel bar (3) and an inclined dowel bar (10) which pass through the core plate to form a three-dimensional space net rack structure; U-shaped connecting reinforced rings (4) are arranged on the outsides of the upper steel wire gauze and the lower steel wire gauze along the circumference of the core plate; and a reinforced cement layer (11) in which the steel wire gauzes are coated through placement is formed between the steel wire gauzes and the core plate. The connecting construction method comprises the following steps: firstly, adjacent laminboards are butted on the construction site according to different positions; secondly, reinforcing steel bars (7) are inserted and fixedly connected; and thirdly, a bearing wall is formed by connection of cast-in-situ concrete columns. A parallel walling, an L-shaped walling, a T-shaped walling and a crossed walling are formed by connection and assembly according to different positions. The precast net rack sandwich wallboard and the connecting construction method can realize factory prefabrication and formation of a wall by placing on the construction site, and have light deadweight, large bearing capacity, quick construction, low manufacturing cost and safety and reliability.

Description

1. Technical field [0001] The invention relates to a prefabricated grid sandwich wallboard and a connection construction method thereof, belonging to the technical field of new building material structures. 2. Background technology [0002] Polystyrene sandwich panel with steel wire frame has scientific and reasonable structure, good mechanical properties, heat preservation and heat insulation, and is popular in many countries in Europe and the United States. The production equipment and technology of grid sandwich panels were introduced into our country in the early 1980s, which caused a sensation in the country. The country has formulated product standards for this purpose, and various places have also published application atlases, which are widely used in construction projects. The good luck didn't last long, a large number of hand-inserted wire boards flooded the market, disturbed the normal order, lowered the price, savage construction, and the plaster on the surface ...
