Description

Technical Field

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

[0002] Pre-buried pipelines in cast-in-place floor slabs refer to the process of burying wire pipes or casings inside the floor slab structure before pouring concrete to facilitate the subsequent laying and maintenance of wires. This practice not only fixes the power lines, but also protects them, avoiding accidents such as damage or short circuits. In order to improve the installation accuracy of the pre-buried pipelines, they need to be protected and positioned.

[0003] For example, the patent with application number: CN202411094757.1 discloses a construction method of a protective positioning device for dense pre-buried pipelines in a cast-in-place floor slab. Pipeline pre-buried positioning stirrups are manufactured according to the floor slab concrete pouring thickness and the number of pre-buried pipelines. The processed positioning stirrups are hoisted to the construction pre-buried pipeline installation site by a tower crane. After the floor slab bottom reinforcement is tied, the positioning stirrups are fixed to the bottom slab reinforcement, the pre-buried pipeline is passed under the positioning stirrups, and fixed firmly with tying wire. After all the pre-buried pipelines are installed, the reinforcement workers can tie the floor slab surface reinforcement. The dense pre-buried pipelines are accurately tied at the designed position to ensure that the pipelines are placed at the specified spacing, thereby effectively preventing displacement during concrete pouring. This method of combining stirrups and positioning devices not only improves the stability of the pipelines, but also solves the problem of pre-buried water and electricity pipelines in the decoration stage in advance during the main structure construction stage, greatly improving construction efficiency and quality.

[0004] Based on the above, the protection and positioning devices for densely embedded pipelines in the currently used cast-in-place floor slabs still have the following problems: 1. The concrete during pouring usually comes into direct contact with the pipeline, which causes the impact force during concrete pouring to easily damage the pre-buried pipeline. The impact force during concrete pouring can also cause the pre-buried pipeline to move, reducing the positioning effect of the pre-buried pipeline. 2. Pipelines are usually positioned using steel frames, which cause the steel frames to be embedded in the poured concrete, increasing construction costs. Steel frames are usually welded on-site, making it impossible to quickly locate embedded pipelines, reducing construction efficiency. Summary of the invention
