Construction method of two-story connection structure of vertical reinforcement in concrete frame structure

Abstract

The invention provides a vertical steel bar two-layer connecting structure of a concrete framework structure. The vertical steel bar two-layer connecting structure comprises an (N+1)th layer horizontal structure, an N-th layer vertical structure and a binding device used for constructing vertical steel bars, wherein the length of the standard vertical steel bars equals to two floor heights; and the binding device comprises an outer climbing frame and a binding frame. A construction method comprises the following construction steps of: constructing a horizontal structure; installing the outer climbing frame; building the binding frame; fixedly connecting the outer side of the binding frame with the top of the outer climbing frame; fixing two vertical movable supporters to the inner side of the lower part of the binding frame, wherein the total number of the vertical steel bars is divided into two halves for length connection; using the binding frame for vertical structure template erection; casing concrete of the vertical structure; using the outer climbing frame for driving the binding frame to climb to a next floor height; and constructing a next layer of horizontal structure until the completion. The characteristics of great diameter and high rigidity of the steel bars of the vertical structure are used, and the connection of the vertical steel bars is changed from the connection in each layer into the connection in every two layers, so that the labor consumption quantity in the construction and the steel bar connection cost are reduced, and good economic benefits are obtained.

Description

technical field [0001] The invention relates to the field of building construction, in particular to a construction method for a vertical reinforcement connection structure of a concrete frame structure. Background technique [0002] With the development of the national economy and construction technology, the scale of the building continues to expand, and the height of the building is also increasing. Among high-rise buildings. The traditional form of vertical reinforcement connection of frame columns is one-story-one connection. The vertical reinforcement of frame columns is cut and blanked according to the requirements of the floor height, and the construction is carried out layer by layer from low to high, and steel bars are used between the steel bar joints between layers. The connector connection is fixed. There are the following technical problems in the construction method of connecting the vertical steel bars of the frame columns one by one: [0003] 1. For a lar...

Problems solved by technology

[0008] The purpose of the present invention is to provide a construction method for the two-layer connection structure of vertical steel bars in a concrete frame structure. To solve the problem of waste of steel bar connectors in the construction process of the existing frame column vertical steel bar layer-one connection, a large amount of scaffolding is required It takes a lot of time for steel bar cutting and blanking, steel bar threading, finished steel bar protection, and steel bar secondary handling, which wastes manpower and material resources. It is also necessary to solve the heavy workload of on-site steel bar connection, which is prone to connection defects. The technical problems that make it more difficult to check and accept the quality of steel bar connections; it is also necessary to solve the technical problems that the position of steel bar joints during construction is difficult to adjust, and the distance specified in the specification cannot be met
