Prefabricated concrete frame and assembling method

Abstract

The invention provides a prefabricated concrete frame and an assembling method, and relates to the technical field of constructional engineering. The prefabricated concrete frame comprises a mountingblock, a frame component and a positioning device, wherein the frame component is positioned right above the mounting block; a grouting groove is formed in the lower surface of the frame component; the positioning device is arranged on the upper surface of the mounting block; the positioning device comprises a positioning rod; the positioning rod is fixedly connected with the upper surface of themounting block; a positioning groove is formed in the lower surface of the frame component; the positioning rod is inserted into the positioning groove and is propped against the inner wall of the positioning groove; the upper surface of the frame component is fixedly connected with a connecting rod; and the upper surface of the mounting block is fixedly connected with a positioning rack. The problems that most of traditional concrete frames need to be held and guided by operators during hoisting, time and labor are wasted, the efficiency is low, certain dangerous factors exist, the concrete frames are inclined easily to bend steel bar connecting ends, the gravity centers of the concrete frames are inclined to cause toppling of the concrete frames and the like are solved, and by application of the device, the safety of equipment can be improved effectively.

Description

technical field [0001] The invention relates to the technical field of construction engineering, in particular to a prefabricated concrete frame and an assembly method. Background technique [0002] The prefabricated concrete frame structure is a structural form in which the concrete frame is decomposed into several beam-column transport units and connected on site to form an overall frame. Because it can realize product standardization, industrialization of production, and rapid construction, it is in line with the goal of modernization of my country's construction industry , so as to get more and more applications, and the connection mode and calculation method of its nodes have become the most dynamic research direction. [0003] Prefabricated concrete frame structure has become one of the most widely used prefabricated concrete structural systems in the world because of its advantages of flexible layout and large indoor space. At present, ordinary prefabricated concrete ...

AI Technical Summary

Problems solved by technology

At present, ordinary prefabricated concrete frame structures usually adopt the construction method of secondary cast-in-place, but most of the existing concrete frames need to be supported and guided by a large number of people when hoisting, which is time-consuming, laborious, inefficient, and there are certain risk factors. The inclination of the frame bends the connecting ends of the steel bars, and the inclination of the center of gravity of the concrete frame causes it to topple over, which needs to be improved
