Post-cast strip device and construction method thereof

Abstract

The invention discloses a post-cast strip device which comprises a foundation base plate. A reinforcement cage is welded inside the foundation base plate. The reinforcement cage comprises a main rib framework composed of a plurality of main ribs, and waist ribs are arranged between the main ribs of the main rib framework and comprise vertical waist ribs and longitudinal waist ribs, wherein the vertical waist ribs and the longitudinal waist ribs are connected between the main ribs. A plurality of symmetrical water stopping steel plates are further longitudinally arranged on the two sides of the reinforcement cage, and the outer surface of the reinforcement cage is further provided with a closing net. The two sides of the reinforcement cage are fixed at the position of a welding point of a lower base plate of the foundation base plate through a plurality of symmetrical fixing tie bars. The post-cast strip device has the advantages that the step of dismantling formworks and a supporting system on the two sides of a post-cast strip after the construction of the base plate is omitted, the hidden danger of water leakage of the post-cast strip is avoided, wood and revolving materials are saved, steel bar processing leftovers are fully utilized, and the steel bar waste is reduced. The hidden safety danger of operation in a narrow space by constructors is avoided, and the construction quality of the post-cast strip is enhanced.

Description

technical field [0001] The invention relates to a post-cast belt device, in particular to a post-cast belt device and a construction method thereof. Background technique [0002] At present, the formwork and support system of the post-cast belt of the base plate are suitable for the formwork and support system on both sides of the post-cast belt of the foundation base plate. However, when the thickness of the base plate increases, the formwork and support system will become difficult to dismantle. Among them, the conventional method is to support wood After the formwork, steel pipe scaffolding or bowl buckle frames are used for reinforcement and support. After the construction of the bottom plates on both sides of the post-casting belt is completed, construction personnel need to drill into the narrow post-casting belt to remove the wooden formwork and scaffolding support system, which poses safety and quality risks. [0003] Therefore, it has become an urgent problem to be ...

AI Technical Summary

Problems solved by technology

[0004] Aiming at the above-mentioned technical problems in the related art, the present invention proposes a post-cast belt device and its construction method, which can be used when it is very difficult to remove the templates and support systems on both sides of the post-cast belt as the thickness of the base plate increases. Closing mesh and steel cage, instead of traditional wooden formwork and scaffolding support system, eliminating the need to remove the formwork and support system on both sides of the post-casting belt after the construction of the base plate is completed
