Construction method of pre-buried filling block in cast-in-place concrete hollow floor

Abstract

The invention discloses a construction method of a pre-buried filling block in a cast-in-place concrete hollow floor. The construction method comprises the following steps that (1), preparation before filling is conducted; (2), a parameter of the light filling block is determined; (3), filling of the light filling block is conducted; (4), anti-floating and fixing treatment is conducted; (5), strengthening treatment is conducted; and (6), concrete pouring is conducted. The problem that a filling block moves during pouring due to unscientific fixing of a filling block of a concrete hollow floor is solved, and the construction method has the technical effect that the filling block is fixed in multiple directions and prevented from making displacement on the whole; in general, according to the construction method of the pre-buried filling block in the cast-in-place concrete hollow floor in the embodiment of the invention, through scientific design of an anti-floating net bar, the light filling block, a floor bottom bar and the specific position dimension, it is ensured that the light filling block, the floor bottom bar and the anti-floating net bar can be all infinitesimally influenced by the outside world even in the pouring and vibrating processes, and smooth implementation of overall construction is ensured.

Description

technical field [0001] The invention relates to the technical field of building concrete pouring construction, and in particular relates to a construction method of pre-embedded filling blocks in cast-in-situ concrete hollow floor slabs. Background technique [0002] The construction technology of cast-in-place hollow-core slabs has been born as early as the last century, and its core technology is also being updated synchronously during the process of being continuously used by people. This technology is a comprehensive application process that needs to consider various requirements. During the construction process, problems must be considered from the perspectives of economy, quality and innovation. This also determines that the construction technology of cast-in-place hollow-core slabs cannot form a perfect construction method in a short period of time. Although many of its links can adapt to the building requirements, the cost is quite high. way to overcome. (Excerpt f...
