Abstract

The invention discloses a staircase prefabricated reinforced concrete fireproof bulkhead structure which is composed of a prefabricated reinforced concrete fireproof bulkhead, a prefabricated concrete stair, staircase stair landing beams and connecting pieces. Bulkhead lifting lugs are arranged on the two sides of the upper portion of the prefabricated reinforced concrete fireproof bulkhead, and the prefabricated reinforced concrete fireproof bulkhead is hung on the top faces of the staircase stair landing beams through the bulkhead lifting lugs on the two sides. The invention further comprises a construction method of the fireproof bulkhead structure. The method comprises the steps of pouring or hoisting of the staircase stair landing beams, hoisting of the inner side prefabricated concrete stair, hoisting of the prefabricated reinforced concrete fireproof bulkhead, and connection of the prefabricated reinforced concrete fireproof bulkhead and the inner side prefabricated concrete stair through the connecting pieces. The prefabricated reinforced concrete fireproof bulkhead is mounted in a hanging mode, structure stability is good, and force transmission is clear; the staircase prefabricated reinforced concrete fireproof bulkhead structure can be produced through a common wallboard production line, and is low in cost, convenient to manufacture and mount, and suitable for being applied to design and construction of prefabricated fireproof bulkheads of scissor stairs of high-rise residences.

Description

technical field [0001] The utility model belongs to the technical field of reinforced concrete structure engineering, in particular to a structure of a prefabricated reinforced concrete fireproof partition in a stairwell and a construction method thereof. Background technique [0002] At present, the installation method of prefabricated reinforced concrete fire partitions in stairwells is mainly that the partitions are installed on the steps of the prefabricated stairs, and the upper side is connected with the stair floor. The edge increases the difficulty of production and reduces the use efficiency of the table formwork; in addition, the large-span stair riser bears a large load, and the stair section and reinforcement increase accordingly; in addition, the fire partition is connected with the stair above and below The overall rigidity is high, and it is easy to crack under the action of earthquake. Contents of the invention [0003] The purpose of the utility model is ...
