Integral joint fixing structure

Abstract

The invention discloses an integral joint fixing structure. The structure comprises an upper sleeve, a lower sleeve and side sleeves. The side sleeves are arranged on one side of the upper sleeve andthe lower sleeve. The upper sleeve and the lower sleeve vertically communicate with each other and are provided with openings. Short steel beams penetrate through the side sleeves, upper and lower flanges are cut off at middle joints of the short steel beams, the inner sides of the side sleeves are provided with openings, and cover plates are installed on the outer sides of the side sleeves. The structure facilitates joint core area grouting, and the upper sleeve, the lower sleeve and the side sleeves can be filled with grout. Compared with field welding which is uncontrollable in outside environment and unreliable in manual operation, in the factory environment, various kinds of equipment and procedures are utilized so that the welding quality can be easily guaranteed, only bolt connection is required in a construction site, the quality is not changed along with the quality of constructors as long as construction is conducted strictly according to regulations, the construction qualityis easy to guarantee, and technological requirements of assembly construction are met.

Description

technical field [0001] The invention relates to the field of construction, in particular to an integral node fixing structure. Background technique [0002] The steel and concrete composite structure has become one of the main forms of high-rise buildings and long-span structures because of its high bearing capacity, good plasticity and ductility, good fire resistance and fire resistance, and simple construction. Regarding the connection of steel beam nodes in composite structures , most of the construction sites use traditional welding. However, node welding is not only a heavy workload and the welding quality is not easy to control. The advantage of industrialized buildings is that many on-site construction technologies are transferred to high-quality mass production in factories. Nodes are the key force transmission in the beam-column structure. If the components can be industrialized in the factory, it will definitely provide a stronger guarantee for their performance, a...

Problems solved by technology

[0003] The purpose of the present invention is to provide an integral node fixing structure to solve the problem of the steel-concrete composite structure in the above-mentioned background technology because of its advantages of high bearing capacity, good plasticity and ductility, good fire resistance and fire resistance, and simple construction. One of the main forms of high-rise buildings and long-span structures. Regarding the joint connection of steel beams in composite structures, traditional welding is mostly used on the construction site. However, joint welding is not only a large workload and the welding quality is not easy to control. The on-site construction technology is transferred to the high-quality mass production in the factory. The nodes are the key force-transmitting components in the beam-column structure. If they can be industrialized in the factory, they will provide a stronger guarantee for their performance. On-site construction will be transformed into column-column connection and beam-beam The connection problem is conducive to the development of building industrialization and prefabricated buildings
