Lattice type keel steel plate net formwork composite wall and construction method thereof

Abstract

The invention discloses a lattice type keel steel plate net formwork composite wall and a construction method thereof. The composite wall comprises keels, steel formworks and fillers, the keels are ofa lattice ultra-light structure and are arranged at intervals in the vertical direction, the steel formworks are steel plate net formworks and wrap all the keels integrally, and the fillers are poured between the steel formworks and wall side columns and in the keels. Each lattice type keel comprises two or more parallel equal-length limb pieces and batten materials connecting the limb pieces with one another. The lattice type keel is adopted, the steel consumption of the keels can be greatly reduced, and therefore the cost is reduced. Filler pouring construction can be facilitated, filling compaction is easier, meanwhile, bridge-cut-off of wall keels are facilitated, the wall is prevented from generating cold and hot bridges, and the heat preservation performance of the wall is improved.The composite wall can be poured on site or installed on site through factory prefabrication, and has wide adaptability.

Description

technical field [0001] The invention belongs to the technical field of buildings, and in particular relates to a lattice-type keel-steel plate mesh-form composite wall and a construction method thereof. Background technique [0002] Traditional composite walls mainly use boards without holes as templates, such as calcium silicate boards, cement fiber boards, etc. Some composite walls use steel wire mesh or steel mesh, but they are not used as templates, and their thickness is extremely thin. The surface of the wall is cracked, and there is no transverse reinforcing rib. Such a composite wall uses a large amount of steel, more materials, and higher cost, and it is difficult to meet the requirements of the wall nailing force. [0003] The traditional composite wall mainly adopts cold-formed thin-walled steel keel. Although the amount of steel used for the keel is low, it has the following defects: a. It needs to be poured in separate warehouses (a relatively independent wareho...

Problems solved by technology

[0002] Traditional composite walls mainly use boards without holes as templates, such as calcium silicate boards, cement fiber boards, etc. Some composite walls use steel wire mesh or steel mesh, but they are not used as templates, and their thickness is extremely thin. The effect of cracking on the surface of the wall, not to mention the lack of transverse reinforcing ribs, such a composite wall uses a large amount of steel, more materials, and higher cost, and it is difficult to meet the requirements of wall nailing force

[0003] The traditional composite wall mainly adopts cold-formed thin-walled steel keel. Although the amount of steel used for the keel is low, it has the following defects: a. It needs to be poured in separate warehouses (a relatively independent warehouse is formed between two adjacent keel columns), Time-consuming and labor-intensive, it is not easy to fill densely; if the hole is opened in the web area of ​​the cold-formed thin-walled steel keel, the keel will be processed twice, which is labor-intensive and reduces the strength of the keel; b. The cold-formed thin-walled steel keel is easy A cold and heat bridge is formed inside and outside, which affects the thermal insulation performance of the wall; c. The horizontal stiffness of the cold-formed thin-walled steel keel is weak, and the keel is prone to deformation when pouring filling materials, which affects the construction quality of the composite wall
