One-time pouring forming construction method of partition beam in elevator shaft

Abstract

The invention discloses a construction method for pouring forming of inner partition beams in an elevator well. The construction method comprises the steps that according to a structural floor layer height and the spacing among the inner partition beams in the elevator well, shear wall formworks, inner partition beam formworks and inner partition beam connecting formworks are made, wherein the inner partition beam connecting formworks are used for connecting the shear wall formworks and the inner partition beam formworks; the shear wall formworks at the two ends of the inner partition beams are mounted; the inner partition beam formworks and the inner partition beam connecting formworks are mounted between the shear wall formworks which are completely mounted; strengthening treatment is conducted on the shear wall formworks, the inner partition beam formworks and the inner partition beam connecting formworks which are completely mounted; Inner partition beam steel bars are bound in the inner partition beam formworks, and shear wall steel bars are bound in the shear wall formworks; and integral concrete pouring is conducted in the shear wall formworks and the inner partition beam formworks, and shear walls and inner partition beams are integrally formed. A whole formwork system is composed of inner partition beam bottom moulds, inner partition beam side moulds and the shear wall formworks, wherein the shear wall formworks are in the area where the inner partition beams are located, so that one-time pouring construction of the elevator well in the shear walls and the structural beam plates is realized, the construction of the inner partition beams is simplified, and the construction process is accelerated.

Description

technical field [0001] The invention relates to the construction of a main structure in the field of engineering construction, in particular to a construction method for one-time pouring and forming of an inner partition beam in an elevator shaft. Background technique [0002] For the inner partition beam used to fix the elevator guide rail in the elevator shaft of the double elevator, I-shaped steel beams or concrete beams are usually poured with secondary reinforcement. How to reduce the construction cost and speed up the construction efficiency when the spacing and the floor height are not integer multiples. [0003] If the I-beam method is used, the construction of the I-beam transportation, hoisting, welding and pre-embedding or post-installing high-strength screws is relatively difficult, and the cost of the I-beam is relatively high, and the installation needs to be erected in the elevator shaft of each floor. platform. [0004] If the secondary pouring method is us...
