A construction method for fast installation and closure of splicing panels for steel beam bolt joints

Abstract

The fast installation and closing construction method of the splicing plate of the steel beam bolt joint section according to the present invention firstly positions the hinge device, and then uses the hinge device to install the splicing plate on the beam body of the closing section, so that the required Before the beam body of the closing section is hoisted, the assembled plate is temporarily fixed in the end face of the beam of the closing section, which effectively ensures the safety of hoisting and facilitates the hoisting operation. When closing, the temporary fixing is removed first, and then the splicing plate is directly rotated to the beam of the closing section. From the outside of the end face to the position to be connected between the beam body of the closing section and the installed beam section, and then the splicing plate is fixed by bolts to complete the closing of the installed beam section and the beam body of the closing section. Hoisting the splicing panels outside the beam body can reduce the construction difficulty of the splicing panel construction of the closing beam body and the installed beam section at high altitude, and can improve the efficiency during the splicing panel construction process of the closing section beam body and the installed beam section , Reduce the construction period and reduce construction safety risks.

Description

technical field [0001] The invention relates to the technical field of bridge engineering, in particular to a construction method for fast installation and closure of splicing plates for steel beam bolt joints. Background technique [0002] With the development of the times, steel structures are widely used in the construction industry due to their light weight, large bearing capacity, and short construction period. During the closing installation process of steel girder erection, generally the splicing plate is placed on the inner side of the beam body of the closing section in advance. The splicing panels are slowly dragged and positioned continuously to make them reach the designated position for fixed construction. This construction method of dragging the splicing plate to the designated position is carried out at high altitude and after the beam body of the closing section is aligned with the installed beam section. Inside the beam body of the closing section, the inte...

Problems solved by technology

This construction method of dragging the splicing plate to the designated position is carried out at high altitude and after the beam body of the closing section is aligned with the installed beam section. Inside the beam body of the closing section, the internal splicing plate is lifted to a height by a chain hoist, and then The construction personnel drag the splicing plate to the corresponding connection position of the splicing plate, and then adjust the splicing plate so that the screw holes on the splicing plate correspond to the screw holes on the beam body of the closing section and the screw holes on the installed beam section. Drag the splicing plate outside the beam body of the closing section, and match the screw holes on the external splicing plate to the screw holes on the beam body of the closing section and the screw holes on the installed beam, and then connect the closing plate through the external splicing plate and the internal splicing plate The section beam body and the installed beam section are connected by bolts. The whole adjustment process needs to constantly position and adjust the position of the inner splice plate and the outer splice plate, which is very complicated, so that the splice plate connects the closed section beam body and the installed beam section at high altitude. The work efficiency is low and the construction period is long. At the same time, due to the narrow space in the box, the harsh operating environment for personnel, and the large number and weight of splicing panels, the construction safety risk is relatively large.

The existing technology is difficult to ensure the safe and efficient installation of the splicing panels of the beam body of the closing section, so as to realize the fast closing alignment of the beam body of the closing section
