Description

Technical Field

[0001] The invention relates to the technical field of corridor trusses, in particular to a corridor truss structure. Background Art

[0002] At present, the corridors between the main buildings of the corridor truss structure often have low rigidity due to their large spans and are prone to large deformations. In order to increase the rigidity of the corridors, the corridor structure often adopts a steel truss structure and provides some additional supports to control the deformation of the corridor during normal use. At the same time, in order to avoid interaction between the main structures due to the existence of the corridors, the corridors are often hingedly connected to the corbel supports extending from the main structures on both sides.

[0003] At present, commonly used large-span truss construction methods include integral lifting method, jacking method, etc. The basic idea is to assemble the entire truss on the ground frame, and then use a jack or tower crane to transport the truss as a whole to the designed position to complete its connection with the main structures on both sides. During the truss lifting process, the shape and force control of the truss is often the main focus of the construction process. It is required to ensure that the stress and deformation of the truss are not exceeded during the entire lifting process. The lifting position of the truss should also be accurately controlled to avoid the displacement of the truss end causing it to deviate from the designed installation position. Obviously, controlling the above problems at the same time is usually a difficulty in the construction of large-span truss corridors.

[0004] In addition, the construction method of large-span trusses also includes the high-altitude bulk method. This construction method transports the truss rods to high altitudes and assembles them one by one. High-altitude operations often make this construction method more dangerous. After assembly to a certain extent, the cantilever structure formed often requires additional structures to control the force and shape, which further increases the complexity of the construction. The sliding mechanism in the corridor truss structure is relatively simple. When the sliding surface is severely worn, it is difficult to remind the staff. Moreover, when repeated sliding occurs, friction is more likely to occur. A certain amount of heat will be generated during multiple frictions. If it 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 of the invention

[0006] The purpose of this section is to summarize some aspects of embodiments of the present invention and briefly introduce some preferred embodiments.

Secondly, when the main structures on both sides move, the truss corridor follows the movement, and the upper anti-slip layer slides on the lower anti-slip layer. If the sliding displacement between the two occurs frequently, heat is generated by friction, and the heat is conducted downward to the heat dissipation fins, and the heat is exported from the shell, thereby reducing the friction heat between the upper anti-slip layer and the lower anti-slip layer. At the same time, the displacement of the movable frame can be exhausted through the inner elastic airbag and the outer elastic airbag, so that the gas is blown to the end of the heat dissipation fin, thereby accelerating the heat dissipation efficiency of the heat dissipation fin, thereby improving the service life of the limited displacement support assembly and further improving the safety of the truss corridor.

[0024] 2. The corridor truss structure increases the wear of the upper anti-slip layer and the lower anti-slip layer and makes the thickness thinner through the reciprocating sliding displacement between the two layers. At this time, the truss corridor moves downward slightly, so that the top seat presses down the annular airbag, and the gas inside the annular airbag can be input into the sealing tube through the air outlet pipe, so that the air pressure controls the touch rod downward through the piston to touch the switch, and the switch can keep the alarm on, so as to serve as a warning and facilitate maintenance work. When the heat on the heat dissipation fins accumulates and cannot be dissipated, the high temperature can heat the internal gas through the air shell. After the gas expands, it can be input upward into the sealing tube through the air pipe, so that the touch rod can also touch the switch to control the alarm to achieve the purpose of alarm, so that relevant personnel can carry out maintenance in time;

[0025] 3. The corridor truss structure can drive the movement of the middle body through the top seat through the movement of the truss corridor, and the middle drives the work-shaped seat to slide and displace on the movable frame, and the movable frame can also achieve sliding displacement through the slide groove, so that the displacement direction has diversity, thereby making the displacement freedom of the truss corridor high, improving the stability of the truss corridor, and also improving the safety of the truss corridor, and through the sliding displacement of the movable frame and the work-shaped seat as the power, it can also realize the pressure on the inner elastic airbag and the outer elastic airbag to achieve exhaust.

The hose cover 522 can close the outer frame 58, so as to prevent dust and impurities from entering and affecting the performance of the displacement limit support assembly 5. The hose cover 522 is retractable and movable, so that the top seat 521 can slide and displace smoothly. The outer frame 58 is fixedly connected below the hose cover 522. Two slide grooves 510 are provided inside the outer frame 58, an intermediate body 523 is fixedly connected to the middle part below the top seat 521, a work-shaped seat 526 is fixedly connected to the outside of the intermediate body 523, an upper support plate 525 is fixedly connected to the bottom of the intermediate body 523, an upper anti-slip layer 524 is fixedly connected to the lower part of the upper support plate 525, and the upper anti-slip layer 524 and the lower anti-slip layer 514 can be made of polytetrafluoroethylene with a low friction coefficient, thereby reducing the resistance between the upper anti-slip layer 524 and the lower anti-slip layer 514, and reducing the wear between the upper anti-slip layer 524 and the lower anti-slip layer 514. The displacement structure 52 is assembled below the truss corridor 1, and the displacement structure 52 is connected to the outer frame 58. A compressed air structure 56 is arranged inside the outer frame 58, and the compressed air structure 56 includes a movable The movable frame 565 is slidably connected to the slide groove 510 at both ends. The slide groove 510 can guide the movable frame 565 to keep the movable frame 565 sliding smoothly. The inner elastic airbags 561 are fixedly connected to the two side walls of the movable frame 565. The inner elastic airbags 561 are provided with a first one-way valve 562. When the work-shaped seat 526 is slid and reset, the compressed inner elastic airbag 561 can be reset, so that air is introduced through the first one-way valve 562 to achieve the purpose of air storage. The first one-way valve 562 can maintain one-way air intake to prevent gas from being discharged. In addition, the two inner elastic airbags 561 can be alternately exhausted when the work-shaped seat 526 moves, so that the gas can smoothly enter the outer elastic airbag 563. Both sides of the two inner elastic airbags 561 are connected The two outer elastic airbags 563 are respectively connected through the one-way tube 566. The one-way tube 566 can maintain one-way air intake, so that the gas can smoothly enter the outer elastic airbags 563. The two outer elastic airbags 563 are fixedly connected to the two sides of the movable frame 565. When the movable frame 565 moves, the outer elastic airbags 563 can be compressed and exhausted. At the same time, the movable frame 565 is reset. The reset of the outer elastic airbag 563 can achieve one-way air intake through the second one-way valve 564, and the two outer elastic airbags 563 can achieve the purpose of switching exhaust. The outer elastic airbag 563 is fixedly connected to the inner wall of the outer frame 58. The second one-way valve 564 is provided on the outer elastic airbag 563. The movable frame 565 is slidably connected with the work-shaped seat 526. The movable frame 565 can guide the work-shaped seat 526.The work-shaped seat 526 is made to slide smoothly along the side of the movable frame 565. The two sides of the work-shaped seat 526 are respectively fixedly connected to the two inner elastic airbags 561. The compressed air structure 56 is connected to the exhaust structure 54. The exhaust structure 54 includes an annular nozzle 541. The upper part of the annular nozzle 541 is connected to two one-way pipes 542. The one-way pipes 542 can maintain one-way gas outlet, so that the gas is smoothly transported to the annular nozzle 541. The exhaust of the annular nozzle 541 can accelerate the air flow near the multiple ends of the heat dissipation fins 513, which is beneficial to the heat dissipation of the heat dissipation fins 513. The two one-way pipes 542 pass through the outer frame 58 and are respectively connected to the two outer elastic airbags 563. The switch 57 is installed on the annular nozzle 541.

The overheat trigger structure 53 is arranged on the support heat dissipation structure 51, and the support heat dissipation structure 51 includes a base 511, and the base 511 is fixedly installed on the corbel support 4. The upper part of the base 511 is fixedly connected with a shell 512, and the shell 512 can protect the upper anti-slip layer 524 and the lower anti-slip layer 514 to prevent them from being exposed and affecting their service life. The upper part of the shell 512 is fixedly connected with the outer frame 58, and the lower support plate 515 is fixedly installed inside the shell 512. The lower support plate 515 is penetrated and installed with heat dissipation fins 513. The heat dissipation fins 513 are annular and dispersed with multiple ends, so that their thermal conductivity is significant, and the ends of the heat dissipation fins 513 extend out of the shell 512, and the upper part of the lower support plate 515 is fixedly connected with the lower anti-slip layer 514, and the upper anti-slip layer 524 is slidably connected to the lower anti-slip layer 514;

[0047] The displacement structure 52 slides on the supporting heat dissipation structure 51 and dissipates the friction heat. When overheated, the overheat trigger structure 53 triggers the switch 57 to control the alarm 59 to sound an alarm. When wear occurs again, the displacement structure 52 presses down the displacement wear trigger structure 55 to trigger the alarm 59 to sound an alarm. Secondly, the displacement of the displacement structure 52 also squeezes the compressed air structure 56, and exhausts air through the exhaust structure 54 to accelerate the air flow speed near the heat dissipation fins 513, thereby improving the heat dissipation.

[0048] In this embodiment, by arranging the support column 2 at the node of the lower chord which is 0.214 times the length of the corridor from the end of the truss corridor 1, and the support column 2 is a steel structure column, it can be used to control the internal force and deformation of the corridor truss in this way, thereby improving the safety of the truss corridor 1. Secondly, when the main structures 3 on both sides move, the truss corridor 1 follows the movement, and the upper anti-slip layer 524 slides on the lower anti-slip layer 514. If the sliding displacement between the two occurs frequently, heat is generated by friction, and the heat is conducted downward to the heat dissipation fins 513, and the heat is exported from the outer shell 512, thereby reducing the friction heat between the upper anti-slip layer 524 and the lower anti-slip layer 514. At the same time, the displacement of the movable frame 565 can be exhausted through the inner elastic airbag 561 and the outer elastic airbag 563, so that the gas is blown to the end of the heat dissipation fin 513, thereby accelerating the heat dissipation efficiency of the heat dissipation fin 513, thereby improving the service life of the limited displacement support assembly 5 and further improving the safety of the truss corridor 1.

[0049] Example 2

[0050] Combined with Figure 9-10 , it is concluded that the displacement wear trigger structure 55 includes an annular airbag 551, which is fixedly connected to the outside of the intermediate body 523 and located between the workpiece seat 526 and the top seat 521. One side of the annular airbag 551 is connected to an air outlet pipe 552, through which gas can be transported into the sealing cylinder 556 to control the movement of the piston 553. The air outlet pipe 552 passes through the outer frame 58 and is connected to the sealing cylinder 556. The sealing cylinder 556 is fixedly connected to the outer frame 58, and the interior of the sealing cylinder 556 is provided with There is a piston 553, and a touch rod 555 and a spring 554 are fixedly connected below the piston 553. The spring 554 can maintain the position of the piston 553 to prevent the piston 553 from moving at will. The bottom end of the spring 554 is fixedly connected to the bottom wall of the sealing cylinder 556. The touch rod 555 passes through the sealing cylinder 556 and corresponds to the switch 57. The touch rod 555 moves to press the switch 57 to control the alarm 59 to alarm, so as to remind relevant personnel to perform maintenance operations. An alarm 59 is fixedly installed on one side of the outer frame 58;

[0051] The overheat trigger structure 53 includes an air shell 531, which is fixedly connected to one end of the heat dissipation fin 513. An air supply pipe 532 is connected to the top of the air shell 531. The air shell 531 is filled with gas. When heat accumulates at the end of the heat dissipation fin 513, the heat heats the entire body, so that the expansion of the gas can control the movement of the piston 553. The upper end of the air supply pipe 532 is connected to the sealing tube 556.

[0052] In this embodiment: through the reciprocating sliding displacement between the upper anti-slip layer 524 and the lower anti-slip layer 514, the time wear of the two is increased and the thickness becomes thinner. At this time, the truss corridor 1 produces a slight downward movement, so that the top seat 521 presses down the annular airbag 551, and the internal gas of the annular airbag 551 can be input into the sealing tube 556 through the air outlet pipe 552, so that the air pressure controls the touch rod 555 to touch the switch 57 downward through the piston 553, and the switch 57 can keep the alarm 59 from sounding an alarm, thereby serving as a warning and facilitating maintenance operations. When the heat accumulates on the heat dissipating fins 513 and cannot be dissipated, the high temperature can heat the internal gas through the gas shell 531. After the gas expands, it can be input upward into the sealing tube 556 through the gas pipe 532, so that the touch rod 555 can also touch the switch 57 to control the alarm 59 to achieve the purpose of alarm, so that relevant personnel can perform maintenance in time.

[0053] Example 3

[0054] Combined with Figure 6 and attached Figure 8 , it is concluded that the compressed air structure 56 includes a movable frame 565, both ends of which are slidably connected in the slide groove 510, and a work-shaped seat 526 is slidably connected to the movable frame 565, and both sides of the work-shaped seat 526 are fixedly connected to two inner elastic airbags 561 respectively;

[0055] The displacement structure 52 includes a top seat 521 , which is installed below the end of the truss corridor 1 . An intermediate body 523 is fixedly connected to the middle of the bottom of the top seat 521 , and an I-shaped seat 526 is fixedly connected to the outside of the intermediate body 523 .

[0056] In the present embodiment: through the movement of the truss corridor 1, the intermediate body 523 can be driven to move through the top seat 521, and the intermediate body 523 can be driven to slide on the movable frame 565, and the movable frame 565 can also achieve sliding displacement through the slide groove 510, so that the displacement direction has diversity, thereby making the truss corridor 1 have a high degree of freedom of displacement, improving the stability of the truss corridor 1, and also improving the safety of the truss corridor 1, and through the sliding displacement of the movable frame 565 and the work-shaped seat 526 as a power, it is also possible to achieve pressure on the inner elastic airbag 561 and the outer elastic airbag 563 to achieve exhaust.

[0057] The working principle of the present invention is as follows: when the main structure 3 on both sides moves, the truss corridor 1 follows the movement, and the truss corridor 1 can drive the top seat 521 and the intermediate body 523 to move, so that the intermediate body drives the upper support plate 525 to move, so that the upper anti-slip layer 524 slides on the lower anti-slip layer 514, and when frequent sliding displacement occurs between the upper anti-slip layer 524 and the lower anti-slip layer 514, the heat is guided downward to the heat dissipation fins 513, and the heat dissipation fins 513 conduct the heat from the shell 512 into the heat dissipation fins 513. When the intermediate body 523 drives the work-shaped seat 526 to slide, the work-shaped seat 526 squeezes the inner elastic airbag 561, so that the inner elastic airbag 561 passes the gas into the outer one-way airbag through the one-way pipe 566, and inputs the gas into the annular nozzle 541 through the one-way pipe 542, so that the annular nozzle 541 sprays the gas to the end of the heat dissipation fin 513, so that the heat dissipation effect of the heat dissipation fin 513 is significant, and when the movable frame 565 slides and moves, the outer elastic airbag 563 can be squeezed to exhaust gas;

[0058] After the upper anti-slip layer 524 and the lower anti-slip layer 514 are worn out due to long-term sliding displacement, their thickness becomes thinner, so that the top seat 521 can press down the annular airbag 551, allowing the gas to enter the sealing tube 556. The air pressure can push the piston 553 and the touch rod 555 to move. The touch rod 555 triggers the switch 57 to control the alarm 59 to sound an alarm. When the heat of the heat dissipation fins 513 continues to accumulate and cannot be discharged, the heat heats the gas inside the gas shell 531. The gas expansion can control the piston 553 to move downward, so that the movement of the touch rod 555 can touch the switch 57 again to control the alarm to sound an alarm.
