Description

Pre-buried straight joint assembly with seat

Technical Field

The utility model relates to a pre-buried formula area seat straight joint sub-assembly belongs to pre-buried spool construction technical field.

Background

Along with the social requirement on the quality of the construction engineering, how to reasonably and effectively reduce the construction cost and improve the market competitiveness of construction enterprises is the first problem to be considered by each construction enterprise. According to the traditional hydropower pre-embedding process, a mode of positioning by drilling holes on a template through an electric drill is adopted for a wire pipe penetrating through the bottom of a beam, and the wire pipe is directly inserted into the holes. Mechanical tapping directly causes template damage, the service cycle of the template is shortened, mechanical tapping directly causes template damage, and the service cycle of the template is shortened; a large amount of sawdust and wood chips are generated on the template in the hole opening process, particularly at the bottom of a beam, the template is difficult to clean, and quality defects such as honeycombs, pitted surfaces, crust skins and the like are easily generated after concrete is formed. If the misplaced and abandoned pipe hole is blocked in time, the slurry leakage phenomenon can be caused, the appearance quality of the concrete forming of the part is seriously influenced, the terrace pollution is caused, and the cleaning is difficult.

The wire tube embedding process is widely applied to the construction of common reinforced concrete structures and has large construction amount. Therefore, a new embedding process which is simple and efficient to operate and is not required to penetrate through a template is found, and the new embedding process is applied to a large-area construction process, so that the product quality is improved, the production cost is reduced, and the effect of achieving twice the result with half the effort can be achieved.
