A construction method of pre-buried light guide hole

Abstract

The invention discloses a construction method for pre-embedded light guide holes, which includes the following steps: checking before lifting; marking out a positioning point; adjusting the elevationof the reference point of an inner mold of a light guide hole; adjusting the deviation of the central positioning axis of the inner mold of the light guide hole; adjusting the axis perpendicularity ofthe inner mold of the light guide hole; binding steel bars; installing a side mold; and pouring concrete. According to the construction method for pre-embedded light guide holes provided by the invention, on one hand, through the reduction in deviation of the pins of the inner mold falling into reserved holes and 'the correction of elevation, axis deviation and perpendicularity', the value to beadjusted after the concrete inner mold of the light guide hole is in place can be reduced, and the difficulty of correction can be reduced; and on the other hand, a reasonable correction sequence is adopted in correction, so that the mutual influence of elevation, axis and perpendicularity adjustment is avoided, the perpendicularity and pre-embedding precision of the light guide hole are ensured,the pre-embedding quality of the light guide hole is improved, and the lighting function of the light guide tube lighting system is ensured. The construction method has broad prospects for popularization and application.

Description

technical field [0001] The invention relates to the technical field of building construction engineering, in particular to a construction method for pre-buried light guide holes. Background technique [0002] As a technology that introduces natural light into the interior for lighting, natural light guide lighting has been widely used in the lighting system of underground garages in the field of housing construction. During the construction process, due to the bulky concrete inner mold of the light guide hole and the asymmetry between the center of gravity and the centroid, it is difficult to lift, place, and correct the inner mold of the light guide hole; 1. The verticality adjustment has a great influence on each other, which increases the difficulty of correction and adjustment after the inner mold of the light guide hole is in place. The pre-embedded quality of the light guide hole directly affects the lighting function of the light guide lighting system, which is the f...
