Embodiment Construction

[0023] The present invention will be described in detail below in conjunction with the accompanying drawings.

[0024] The present invention comprises the following steps:

[0025] A. Make a corresponding number of pre-embedded casings according to the required number of plumbing well openings, determine the diameter of the pre-embedded casings according to the diameter of the plumbing well pipes, and determine the length of the pre-embedded casings according to the thickness of the floor. Use chalk to mark the dimension line on the seamless steel pipe according to the size, and the operator cuts the seamless steel pipe into the required length steel pipe section according to the dimension line when cutting;

[0026] B. According to the layout of the plumbing wells in the engineering design, the iron rods are cut into corresponding lengths to make two upper and lower frame structures 2. According to the size of the reserved holes and the specifications and shapes of the water ...

Abstract

The invention discloses a construction method for a prestressed concrete floor slab reserved with a water-heating pipeline well opening, which comprises the following steps of: A, manufacturing a corresponding quantity of embedded sleeves; B, dividing a plurality of iron rod pieces into an upper layer and a lower layer to weld the embedded sleeves into embedded pieces; C, accurately setting out on a laid floor slab mould, and marking the central position of water supply and drainage pipes in the water-heating pipeline well by paint; D, carrying the embedded pieces to the floor slab mould and fixing the embedded pieces firmly; E, inserting prestressed reinforcing steel bars among the embedded pieces; F, performing the acceptance of concealed work; and G, pouring concrete. The invention overcomes a plurality of inconveniences of prestressed reinforcing steel wires, solves the problem that the water-heating pipeline well cannot be reserved as unbounded prestressed concrete steel bars pass through the water-heating pipeline well floor slab, guarantees high accuracy of the reserved pipeline position in the water-heating pipeline well, simplifies operation rules, saves cost and reduces labor intensity, saves a lot of effective time for an project with a limited construction period and a construction process insertion, and simultaneously brings a great of economic benefits.

Description

technical field [0001] The invention relates to a construction method of a prestressed concrete floor, in particular to a construction method of a prestressed concrete floor with reserved openings of water heating wells, which is used for the construction of prestressed concrete floors with openings of pouring water heating wells and many pipelines. Background technique [0002] The cast-in-place prestressed floor slab belongs to the large-span space structure. It not only provides a flexible layout of the building plane, improves the use function and effective area of ​​the building, but also reduces the structural height and increases the indoor clear height. It has the advantages of saving space and integrating beams and slabs , The characteristics of flat bottom. However, the prestressed steel strands are densely arranged in the floor slab, and the steel strands pass through the hole of the water heating well, and there are many pipelines in the water heating well, so th...
