Assembly type building structure system and stand column and cross beam connecting device thereof

Abstract

The invention relates to an assembly type building structure system and a stand column and cross beam connecting device thereof. The connecting device comprises a fixed sleeve arranged outside a standcolumn in a sleeving manner and detachably connected with the stand column, a first connecting disc and a second connecting disc, wherein the first connecting disc and the second connecting disc arearranged on the fixed sleeve in a sleeving manner and are oppositely arranged, multiple mounting positions arranged around the circumferential direction of the fixed sleeve are formed between the first connecting disc and the second connecting disc in a matched manner, the mounting positions are in one-to-one corresponding to cross beams, the cross beams are inserted into the mounting positions, and are detachably connected with the first connecting disc and the second connecting disc, during mounting, the stand column is inserted into the fixed sleeve to be fixed, the cross beams are insertedinto the corresponding mounting positions between the first connecting disc and the second connecting disc to be fixed, through the connecting device, connecting of the stand column and the cross beams can be achieved, the strength of the beam bodies cannot be affected, operation is easy, mounting speed is high, even if the structure is changed, dismounting and adjusting can be carried out again,the original beam bodies cannot be scrapped, flexibility and changing are achieved, repeated use of the beam bodies can be facilitated, and production cost is reduced.

Description

technical field [0001] The invention relates to the field of prefabricated buildings, in particular to a prefabricated building structure system and a connecting device for columns and beams thereof. Background technique [0002] Aluminum prefabricated buildings are widely accepted by the public because of their simple and easy installation, light structure and high strength, various shapes and more comfortable touch than other metal buildings. At present, when the column in the aluminum assembly is connected to multiple beams, the beams are generally fixed directly on the column by welding, but the connection is made by welding. Aluminum alloy welding has a heat-affected zone, which will reduce the strength of the component. According to the design requirements, the section of the component needs to be thickened, which leads to an increase in cost, and the installation method is complicated and time-consuming. Once the components are assembled and welded incorrectly, it is ...

At present, when the column in the aluminum assembly is connected to multiple beams, the beams are generally fixed directly on the column by welding, but the connection is made by welding. Aluminum alloy welding has a heat-affected zone, which will reduce the strength of the component. According to the design requirements, the section of the component needs to be thickened, which leads to an increase in cost, and the installation method is complicated and time-consuming. Once the components are assembled and welded incorrectly, it is easy to cause the component to be scrapped, which is not conducive to the repeated use of the component
