A method for constructing a prefabricated concrete scissors staircase standard floor partition wall

Abstract

A method for constructing a prefabricated concrete scissors staircase standard floor partition wall, belonging to the technical field of civil engineering, the invention installs the lightweight partition wall panel section on the concrete scissors by connecting the angle steel section and the concrete scissors staircase section with connectors and self-tapping screws The position of the partition wall of the standard floor of the staircase makes the partition wall of the standard floor of the concrete scissors staircase constructed by the assembly method good in quality, high in work efficiency and low in cost.

Description

technical field [0001] The invention belongs to the technical field of civil engineering, and in particular relates to a method for constructing a standard-floor partition wall of an assembled concrete scissors staircase. Background technique [0002] It is not easy to guarantee the construction quality of concrete stairs in construction engineering, low efficiency, labor and time-consuming, and high construction costs, which are common phenomena in the construction process of concrete stairs. It has become a consensus in the industry that concrete stairs are constructed by prefabricated methods, which have the advantages of high quality, high work efficiency, low construction cost and environmental friendliness. For the prefabricated concrete scissors stairs, the standard layer partition wall is either traditionally built on the stair section, or the beam supporting the partition wall is set, and then the wall is built or the partition wall is installed on it. General, low...

For the prefabricated concrete scissors stairs, the standard layer partition wall is either traditionally built on the stair section, or the beam supporting the partition wall is set, and then the wall is built or the partition wall is installed on it. General, low efficiency, high construction cost

[0003] In August 2019, "Anhui Architecture" published an article "Design and Application of Prefabricated Scissor Ladder with Butterfly Beams", DOI: 10.16330 / j.cnki.1007-7359.2019.08.27, using prefabricated concrete beams and lightweight partition walls The scissor ladder partition wall made of panels still belongs to the traditional installation method of lightweight partition panels. Since the steps on both sides of the precast concrete beams are inclined stairs, there is no flat working surface to use, which makes installation very inconvenient. Both quality and efficiency will be adversely affected

[0004] Utility model patent authorization specification CN201721324457.3 discloses an assembled scissors staircase, which relates to the field of construction technology and is used to solve technical problems such as complex formwork support of cast-in-place staircase components and slow construction speed of secondary masonry ladder partition walls. It includes a prefabricated ladder beam, two intersecting prefabricated stairs erected on the prefabricated ladder beam and a prefabricated partition wall between the two prefabricated staircase beams, the prefabricated ladder beam includes vertical beams and corbels connecting the bottom ends of the vertical beams, The corbel beam is provided with an inner groove 1 along the longitudinal direction, and an inner groove 2 is arranged along the transverse center position, and a protrusion cooperating with the inner groove 1 is arranged at the connection between the bottom of the prefabricated stairs and the prefabricated ladder beam, and the prefabricated There are cantilever beams connected to the inner groove two on both sides of the partition wall. The top surface of the prefabricated partition wall is provided with a trapezoidal groove, and the bottom surface is provided with a trapezoidal bump matching the trapezoidal groove. However, the size of the prefabricated partition wall of this utility model is relatively small Large, difficult to lift and even more difficult to install, and at the same time, the connection relationship is not clearly expressed

However, the size of the prefabricated partition wall of this utility model is relatively large, it is difficult to manufacture and lift, and it is even more difficult to install. At the same time, the connection relationship is not clearly expressed.
