Concrete reinforcing frame combined formwork

Abstract

The invention discloses a concrete reinforcing frame combined formwork, which consists of a side post formwork and a lintel formwork through being combined, wherein the lintel formwork is arranged at the upper end of the side post formwork; each of the lintel formwork and the side post formwork adopts a corner-element-fixation formwork-length-adjustable and steel-wood-combining structure; a pre-splicing method and shaping construction are adopted, so that the relying on the skill of workers is ignored; components such as vertical beams and connecting elements are connected with a sealing end plate; the mounting, dismounting and transportation integrality is high; scattered elements are few; press blocks are tightly pulled through wall penetrating opposite pulling screw bolts and directly act on the formwork; the horizontal displacement is limited through the friction between the formwork and the wall surface; the plurality of press blocks distributed at intervals in the longitudinal direction form discontinuous vertical beams; and the effect of preventing the formwork expansion in the formwork deformation range is achieved. The concrete reinforcing frame combined formwork has the advantages that the mounting and the dismounting are fast; the concrete forming effect is good; the material consumption is low; the universality is high; the cyclic use times are many; the labor consumption is low; the scattered elements are few; and the transportation is convenient, and the like.

Description

technical field [0001] The invention belongs to the field of concrete structure construction, and in particular relates to a formwork structure of a reinforced concrete reinforcement frame for a door and window opening reserved for a filling wall built with concrete aerated blocks. Background technique [0002] For the infill wall built with concrete aerated blocks, openings for doors and windows shall be reserved, and reinforced concrete reinforcement frames shall be set. The reinforced concrete reinforced frame is a secondary structure, and its quality has little effect on the safety of the structure for the main building. The component cross-section of the reinforced concrete frame is often designed to be The smaller ones are usually 200mm×100mm, 100mm×100mm. The smaller the cross-section components, the higher the technical requirements for formwork assembly. Improper reinforcement will easily cause concrete defects such as concrete expansion, component distortion, and c...

Problems solved by technology

Its technical determination is: the formwork system and the reinforcement system are independent, and consume a lot of turnover materials; the one-time investment is large; the formwork is heavy and inconvenient to transport; the labor cost is high and uneconomical
