A construction method of pvc piping for the inlet and outlet lines of the distribution box at the bottom of the beam

Abstract

The invention discloses a construction method for PVC piping of incoming and outgoing lines of a distribution box at a beam bottom. The links of integrated module machining and manufacture, integrated module installation, connection of the PVC piping and an integrated module are conducted and the problems that in a traditional beam bottom formwork hole forming construction method, a formwork is seriously damaged, the service life of the formwork is seriously shortened, and the piping is badly damaged in the formwork detaching process are solved; the problems that in a PVC lug-contained joint connection construction method, when the height of a beam is over 500 mm, a PVC lug-contained joint is difficult to fix, labor cost is too high, the PVC lug-contained joint is likely to be vibrated and damaged when not firmly fixed, the joint can not be found after the formwork is detached, and the post treatment difficulty is high are solved. By the adoption of a modularized manufacturing mode, joint quality and the machining speed are guaranteed, cost of engineering is reduced, the efficiency of the engineering is improved, and a powerful guarantee is provided for accelerating a construction schedule. The construction method can be suitable for building installation engineering of PVC matched pipe beam penetration of the incoming and outgoing lines of distribution boxes of standard floors and houses of all the urban complex, other office, hotel and department projects and the like.

Description

technical field [0001] The invention relates to a construction method of PVC piping for inlet and outlet lines of a distribution box at the bottom of a beam, in particular to a construction method for PVC piping of an inlet and outlet line of a distribution box at the bottom of a beam for an integrated module of prefabricated PVC pipe joints. Background technique [0002] The PVC piping for the incoming and outgoing lines of the indoor distribution box of the standard floor of the urban complex or other offices, hotels, apartments, etc. must pass through the beams when the main structure is pre-embedded. The traditional hole-opening construction method of the beam bottom formwork has great damage to the formwork, low turnover life of the formwork, and great damage to the piping when the formwork is removed; the new PVC lug joint connection construction method avoids the disadvantages of the traditional hole-opening construction method. However, the labor cost is too high, an...

Problems solved by technology

The traditional hole-opening construction method of the beam bottom formwork has great damage to the formwork, low turnover life of the formwork, and great damage to the piping when the formwork is removed; the new PVC lug joint connection construction method avoids the disadvantages of the traditional hole-opening construction method. But the labor cost is too high, and when the beam height exceeds 500mm, it is difficult to fix the PVC ear joints. If the fixation is not firm, it is easy to be damaged by vibration. After the formwork is removed, the joints cannot be found, and the post-processing is difficult.
