TECHNICAL FIELD

[0001] The present application relates to the technical field of building construction, in particular to a large-span multi-layer steel truss corridor and a construction method. BACKGROUND

[0002] With the continuous construction and development of the city, people's design requirements for building use function and appearance modeling are getting higher and higher. Steel truss corridor, as a kind of structure outside the building, can expand space and improve space utilization, and is more and more applied to buildings. When installing some large-span multi-layer steel corridor, the whole lifting installation method is usually used to install each layer of steel truss corridor independently, that is, after the whole steel truss corridor of each layer is assembled on the ground, the assembled steel truss corridor is lifted to the connection position by a crane, and then it is installed with the building, and then the next layer of steel truss corridor is lifted again.

[0003] When constructing a multi-layer steel truss corridor, after the upper layer of steel truss corridor is installed, a plurality of connecting beams need to be hoisted in sequence to fix the upper layer of steel corridor before hoisting the lower layer of steel truss corridor, and then the hoisted lower layer of steel truss corridor is fixed with the plurality of connecting beams hoisted before. In this process, repeated hoisting operations will cause complicated construction steps, which will reduce the construction efficiency of the multi-layer steel truss corridor. SUMMARY

[0004] The purpose of the present application is to provide a large-span multi-layer steel truss corridor and a construction method to solve the above technical problems.

[0007] Step two: start the hoisting equipment to pull the steel column, truss, stand and steel beam one to move up synchronously, so that the through hole on the steel beam one slides on the stabilizing rod. During the upward movement, the distance between the steel beam one and the steel beam two will increase due to the gravity of the steel beam two;

[0008] Step three: after the distance between the steel beam one and the steel beam two increases by a certain distance, the linkage mechanism controls the distance between the steel beam one and the steel beam two, and avoids the further increase of the distance between the steel beam one and the steel beam two, and the distance between the steel beam one and the steel beam two is equal to the height of the channel two;

[0009] Step four: in the process of expanding the distance between steel beam one and steel beam two, the position between steel beam one and steel beam two is vertically supported by the stabilizing unit to provide vertical positioning;

[0010] Step five: then the hoisting equipment continues to work, and drives steel beam one and steel beam two to move up synchronously, and then under the action of the gravity of steel beam three, the distance between steel beam two and steel beam three is further increased, and when the distance between steel beam two and steel beam three is equal to the height of channel two, the vertical support between steel beam two and steel beam three is performed by the stabilizing unit to keep the distance between steel beam two and steel beam three fixed;

[0011] Step six: then the hoisting equipment continues to pull steel beam one, steel beam two and steel beam three to move up synchronously, and when the truss moves to the bottom surface of the stop plate, the hoisting equipment stops working;

[0012] Step seven: then the moving unit is started to control the support plate one and the support plate two to move, so that the support plate one and the support plate two slide between steel beam one and steel beam two and between steel beam two and steel beam three, and then the distance between steel beam one and steel beam two and the distance between steel beam two and steel beam three are further fixed.

[0016] 3、The action of the connecting mechanism can make the abutting plate abut the two sliding seats transversely and cooperate with the abutting rod to fix the fixed box and the mounting seat longitudinally, effectively keeping the distance between steel beam one and steel beam two and the distance between steel beam two and steel beam three fixed, and further improving the connection stability of steel beam one, steel beam two and steel beam three;

[0030] like Figure 1-Figure 7 The present invention provides a long-span multi-layer steel truss corridor and a construction method, comprising the following steps:

[0031] Step 1: Workers weld steel columns 10 between the two ends of the two trusses 9, weld columns 11 on the top of steel beam 1 5, and weld the top of column 11 to the bottom of truss 9. Then, workers arrange steel beam 3 7, steel beam 2 6, and steel beam 1 5 in order from bottom to top and place them between the two buildings 1. The through holes 8 on steel beam 3 7, steel beam 2 6, and steel beam 1 5 are connected to the outside of the stabilizer bar 3, and the lifting equipment at the top of the building 1 is connected to the steel columns 10.

[0032] Step 2: Start the hoisting equipment, which will pull the steel column 10, truss 9, column 11 and steel beam 1 5 upward synchronously, causing the through hole 8 on steel beam 1 5 to slide on the stabilizer bar 3. During the upward movement, due to the gravity of steel beam 2 6, the distance between steel beam 1 5 and steel beam 2 6 will increase, causing the slide 26 to drive the slider 27 to slide in the slide 28, realizing the swing of the cross bar 29;

[0033] The third step is to slide the sliding block 31 toward the recess 32 so that one end of the sliding block 31 contacts the bottom end of the pressure plate 36. When the sliding blocks 31 on both sides of the pressure plate 36 approach each other, the inclined surface of the pushing block 31 slides on the inclined edge 37 of the pressure plate 36 to move the pressure plate 36 downward. The pressure plate 36 pulls the telescopic rod 34 to slide inside the fixed cylinder 33, stretching the spring 1 35. When the bottom end of the pressure plate 36 contacts the side wall of the sliding block 27, the pressure plate 36 is abutted against the two sliding blocks 27, which can prevent the sliding seat 26 from continuing to slide, prevent the cross rod 29 from continuing to swing, and prevent the distance between the steel beam 1 5 and the steel beam 2 6 from further increasing, thereby effectively fixing the distance between the steel beam 1 5 and the steel beam 2 6, and the distance between the steel beam 1 5 and the steel beam 2 6 is equal to the height of the channel 2 4.

[0034] Step 4: As the distance between the first steel beam 5 and the second steel beam 6 increases, the two adjacent toothed plates 40 approach each other. The meshing of the toothed plates 40 and the gear 42 causes the gear 42 to rotate, which in turn drives the rotating shaft 41 to rotate. The rotating shaft 41 drives the pressure rod 43 to swing, causing the pressure rod 43 to rotate to the top of the mounting seat 39.

[0035] When the pressing rod 43 squeezes the locking rod 46, the end of the pressing rod 43 moves downward and compresses the second spring 47. When the pressing plate 36 abuts the two sliders 27, the pressing rod 43 rotates to a vertical state, which makes the lock hole 44 in a vertical state, stops squeezing the locking rod 46, and under the reverse force of the second spring 47, the locking rod 46 is inserted into the lock hole 44 to achieve the locking of the pressing rod 43. This can avoid the situation where the steel beam 1 5 and the steel beam 2 6 are compressed and the spacing becomes smaller. By the lateral abutment of the two slides 26 by the pressing plate 36 and the longitudinal fixation between the fixing box 38 and the mounting seat 39 by the pressing rod 43, the spacing between the steel beam 1 5 and the steel beam 2 6 is effectively kept fixed, thereby improving the stability of the distance between the steel beam 1 5 and the steel beam 2 6 being equal to the height of the channel 2 4.

[0036] Step 5: As the hoisting equipment continues to work, it will drive the steel beam 1 5 and the steel beam 2 6 to move upward synchronously, and then under the action of the gravity of the steel beam 3 7, the distance between the steel beam 2 6 and the steel beam 3 7 will be further increased. When the distance between the steel beam 2 6 and the steel beam 3 7 is equal to the height of the channel 2 4, the pressure plate 36 will be caused to abut the two slides 26 laterally, and the pressure rod 43 will be used to fix the fixing box 38 and the mounting seat 39 longitudinally, effectively maintaining the distance between the steel beam 2 6 and the steel beam 3 7 fixed;

[0037] Step 6: The hoisting equipment will then continue to pull the steel beam 1 5, the steel beam 2 6 and the steel beam 3 7 upwards synchronously. When the truss 9 moves up to contact the bottom surface of the stop plate 12, the hoisting equipment will stop working.

[0038] Step seven: then start the motor 21, the motor 21 drives the worm 22 rotation, the worm 22 drives the worm gear 20 rotation, the worm gear 20 will drive the screw rod 19 rotation, through the screw rod 19 and the support plate two 17 threaded connection will make the support plate two 17 in the recess one 13 inside horizontal sliding, and make the support plate two 17 drive the adapter rod 18 in the recess one 13 sliding, and the support plate one 16 in the recess two 14 inside sliding, make the support plate two 17 and the support plate one 16 sliding to the steel beam one 5 and the steel beam two 6 between and the steel beam two 6 and the steel beam three 7 between, effectively realize to the steel beam one 5 and the steel beam two 6 support and the steel beam two 6 respectively with the steel beam one 5 and the steel beam three 7 between the further fixed interval, further improve the connection stability of multilayer steel truss.
