Construction method for prefabricated perforated type filling module of ribbed cast-in-place concrete floor slab

Abstract

The invention discloses a construction method for a prefabricated perforated type filling module of a ribbed cast-in-place concrete floor slab. The method comprises the following steps of: constructing a template support frame body; arranging a bottom template of the floor slab; binding two-way bottom-row reinforcements on the bottom template; binding bottom-row transverse ribbed beam reinforcements and bottom-row longitudinal ribbed beam reinforcements of ribbed beams on the two-way bottom-row reinforcements, and binding top-row transverse ribbed beam reinforcements and top-row longitudinal ribbed beam reinforcements on the upper parts of the bottom-row transverse ribbed beam reinforcements and the bottom-row longitudinal ribbed beam reinforcements, thereby forming a plurality of squares; placing two high cushion blocks in the first of every two squares; arranging longitudinal bracket reinforcements in each row of squares; arranging a prefabricated filling module in each square; arranging longitudinal anti-floating reinforcements on each prefabricated filling module; binding two-way top-row reinforcements of the floor slab on the longitudinal anti-floating reinforcements; and pouring floor slab concrete. The method is firm in structure, safe and reliable, anti-floating measures are effective, and the self weight of the floor slab is reduced.

Description

technical field [0001] The invention relates to a dense-rib cast-in-place concrete floor slab, in particular to a construction method for prefabricated perforated filling modules of a dense-rib cast-in-place concrete floor slab. Background technique [0002] In my country's current industrial and civil buildings, reinforced concrete structure has the characteristics of wide source of raw materials, mature construction technology and low cost, so it is still the most widely used structural form. However, due to the higher requirements of high-rise buildings, large spaces, flexible partitions and earthquake resistance, it is very necessary to study new reinforced concrete structural systems with advanced technology, reasonable economy and high quality. The cast-in-place concrete hollow-core slab greatly improves the flexibility and economy of construction applications due to its light weight, good rigidity, and full use of floor height. Compared with the traditional technolog...
