A gallery truss structure

Abstract

The application discloses a gallery truss structure and belongs to the technical field of gallery truss structures. The gallery truss structure is characterized in that a support column is arranged at a lower chord node at a position 0.214 times the length of the gallery away from the end of the gallery truss, so as to control the internal force and deformation of the gallery truss and improve the safety of the gallery truss. When the two main body structures move, the gallery truss moves along with the movement, and the upper anti-sliding layer slides on the lower anti-sliding layer.

Meanwhile, the displacement of the movable frame can be exhausted through the inner elastic air bag and the outer elastic air bag, so that the gas is blown to the end of the heat dissipation fin, the heat dissipation efficiency of the heat dissipation fin is improved, and the service life of the displacement limiting support assembly is prolonged, and the safety of the gallery truss is further improved.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of corridor truss, in particular to a corridor truss structure. BACKGROUND

[0002] At present, the corridor between the main buildings of the corridor truss structure is large in span, and its rigidity is often small, which is easy to produce large deformation. In order to increase the rigidity of the corridor, the steel truss structure form is often used for the corridor structure form, and some additional supports are arranged at the same time to control the deformation of the corridor in the normal use state. At the same time, in order to avoid the interaction between the main structures caused by the existence of the corridor, the corridor is often hinged connected with the outrigger support of the main structure on both sides.

[0003] At present, the commonly used large-span truss construction methods include integral lifting method, jacking method and the like. The basic idea is to assemble the whole truss on the ground jig frame, and then transport the truss to the designed position by the jack or tower crane, and complete the connection with the main structure on both sides. In the process of lifting the truss, the shape and force control of the truss are often the main concern in the construction process, which requires that the stress and deformation of the truss should not be over limit in the whole lifting process, and the position of the truss lifting should also be accurately controlled to avoid the displacement of the end of the truss causing deviation from the designed installation position. Obviously, it is difficult to control the above problems at the same time, which is the difficulty of the construction of large-span truss corridor.

[0004] In addition, the construction method of large-span truss also includes high-altitude bulk method. This construction method transports the truss members to high altitude and assembles them in sequence. High-altitude operation often leads to higher risk of this construction method. Moreover, when assembled to a certain extent, the cantilever structure formed often needs additional structure for force and shape control, which further increases the complexity of construction. Moreover, the sliding mechanism in the corridor truss structure is relatively simple, and when the sliding surface is seriously worn, it is difficult to remind the workers. Moreover, when repeatedly sliding, it is more likely to produce friction, and a certain amount of heat will be generated in the repeated friction. If the heat is not dissipated in time, it will affect the performance of the sliding surface.

[0005] Therefore, it is of great significance to study a new corridor truss structure to solve the above problems. SUMMARY

[0056] In this embodiment: through the movement of the truss corridor 1, the intermediate body 523 can be driven to move by the top seat 521, the work-shaped seat 526 is slidingly displaced on the movable frame 565, and the movable frame 565 can also be slidingly displaced through the sliding groove 510, so that the displacement direction has diversity, so that the displacement degree of freedom of the truss corridor 1 is high, the stability of the truss corridor 1 is improved, and the safety of the truss corridor 1 is also improved, and the sliding displacement of the movable frame 565 and the work-shaped seat 526 can also be used as power to press the inner elastic air bag 561 and the outer elastic air bag 563 to realize exhaust.

[0057] The working principle of the present application is that when the main body structure 3 on both sides moves, the truss corridor 1 follows the movement, the truss corridor 1 can drive the top base 521 and the intermediate body 523 to move, the intermediate body drives the upper support plate 525 to move, the upper wear-resistant layer 524 slides on the lower wear-resistant layer 514, and when the upper wear-resistant layer 524 and the lower wear-resistant layer 514 slide frequently, heat is guided downward to the heat dissipation fins 513, the heat dissipation fins 513 guide heat out of the shell 512 to dissipate heat, and when the intermediate body 523 drives the work-shaped seat 526 to slide, the work-shaped seat 526 extrudes the inner elastic air bag 561, the inner elastic air bag 561 makes the gas enter the outer one-way air bag through the one-way pipe 566, and enters the annular jet head 541 through the one-way connecting pipe 542, so that the annular jet head 541 sprays gas to the end of the heat dissipation fin 513, so that the heat dissipation effect of the heat dissipation fin 513 is remarkable, and when the movable frame 565 slides, the outer elastic air bag 563 can be extruded to exhaust gas;

[0058] When the upper wear-resistant layer 524 and the lower wear-resistant layer 514 slide for a long time and wear, the thickness becomes thin, the top base 521 can press the annular air bag 551, the gas enters the sealed cylinder 556, the gas pressure can drive the piston 553 and the touch rod 555 to move, the touch rod 555 touches the switch 57 to control the alarm 59 to alarm, and when the heat of the heat dissipation fin 513 cannot be discharged, the heat heats the gas in the gas shell 531, the gas expands to control the piston 553 to move downward, so that the touch rod 555 moves to press the switch 57 again to control the alarm to alarm.
