Description

Technical Field

[0001] The present invention belongs to the technical field of building construction, and more specifically, particularly relates to a protection and positioning device for densely embedded pipelines in a cast-in-place floor slab. Background Art

[0002] Embedding pipelines in a cast-in-place floor slab means that before concrete pouring, electric conduits or sleeves are pre-embedded inside the floor slab structure to facilitate subsequent laying and maintenance of electric wires; this practice not only fixes the electric wire routes but also protects the electric wire routes, avoiding accidents such as damage or short circuits of the electric wire routes. In order to improve the installation accuracy of the embedded pipelines, it is necessary to protect and position the embedded pipelines.

[0003] For example, in the patent with the application number: CN202411094757.1, a construction method for a protection and positioning device for densely embedded pipelines in a cast-in-place floor slab is disclosed. According to the thickness of the floor slab concrete pouring and the number of embedded pipelines, pipeline embedded positioning stirrup bars are fabricated. The fabricated positioning stirrup bars are hoisted to the construction site for embedded pipeline installation by a tower crane. After the bottom reinforcement of the floor slab is tied, the positioning stirrup bars are fixed on the bottom reinforcement, the embedded pipelines are passed under the positioning stirrup bars, and are firmly fixed with binding wires. After all the embedded pipelines are installed, the steel bar workers can tie the floor slab surface reinforcement; the densely embedded pipelines are accurately tied to the designed positions to ensure that the pipelines are arranged at the specified spacing, thus effectively preventing displacement during concrete pouring; this method combining stirrup bars and positioning devices not only improves the stability of the pipelines but also pre-solves the problem of embedding water and electricity pipelines in the decoration stage during the main structure construction stage, greatly improving the construction efficiency and quality.

[0004] Based on the above, the currently used protection and positioning devices for densely embedded pipelines in a cast-in-place floor slab still have the following problems:

[0005] 1. The concrete during pouring usually directly contacts the pipelines, resulting in the impact force during concrete pouring being likely to damage the embedded pipelines, and the impact force during concrete pouring will also cause the embedded pipelines to move, reducing the positioning effect of the embedded pipelines;

[0006] 2. Generally, a steel bar frame is used to position the pipelines, resulting in the steel bar frame being embedded in the poured concrete, increasing the construction cost, and the steel bar frame is generally welded on-site, unable to quickly position the embedded pipelines, reducing the construction efficiency.
