Description

[0002] The steel structure corridor is constructed with overall hydraulic lifting technology. After the corridor is installed, its bottom is more than 100 meters from the ground. Conventional curtain wall construction hanging baskets cannot meet the installation requirements of the aluminum curtain wall at the bottom of the corridor. It is also impossible to set up a full-hall steel pipe scaffolding because of the high cost and high safety risks. Taking various factors into consideration, a track-type hanging basket can be used for construction to achieve the sliding of the hanging basket at the bottom of the corridor. However, if a hard rail, such as a steel rail, is used, the rail needs to be installed on the upper part of the aluminum plate, and it is difficult to remove the rail and close the aluminum curtain wall in the later stage. Therefore, a soft-rail hanging basket, such as a cableway hanging basket, can be selected as an operating platform for the construction of the aluminum curtain wall at the bottom of the corridor.

Step 804: A sliding device is installed on each flexible cableway, the basket lifting wire rope is connected to the basket, and the movable pulley is installed on the flexible cableway. The movable pulley hook is tied with the basket lifting wire rope, and the basket slides along the flexible cableway at the bottom of the corridor by pulling the flexible cableway. Step 805: A safety rope is independently tensioned along the span direction on the operating platform of each basket. Step 806: The steel structure corridor is lifted as a whole, and the basket is assembled. Step 807: The basket lifting wire rope is passed around the basket, and the basket load test, acceptance and handover work are carried out. Step 808: After the acceptance is completed, the basket is lifted from the middle of the corridor to its position, and slid to the construction site for construction.

[0039] In a preferred embodiment, the flexible cableway is a cableway steel wire rope with a diameter of 30 mm. The cableway steel wire rope is tensioned between the cableway fixed brackets on both sides of the bottom of the steel structure corridor, including the following steps: inserting one end of the cableway steel wire rope through the through hole of the steel plate of the cableway fixed bracket on one side, placing the protective steel ring of the cableway steel wire rope between the steel plate and the cableway steel wire rope before bending back, and tightening the cableway steel wire ropes on both sides with a buckle at the protective steel ring, and locking them in the buckle. And if Fig. 9 As shown, the first buckle 81, the second buckle 82, the third buckle 83 and the fourth buckle 84 are installed at intervals of 180 mm, and a safety ring 85 should be made between the third buckle 83 and the fourth buckle 84.

[0041] Example 3

[0042] A specific embodiment of the present invention is described below:

[0043] The height of the steel structure corridor of this embodiment is 9m, the span in the length direction is 38.7m, and the span in the width direction is 22.6m. If the cableway is selected to slide along the length direction of the steel structure corridor, the sliding distance of the hanging basket is 38m, and the cableway needs to be installed for 38.7m. The cableway disturbance deformation is large, and because the two sides along the length direction are tower structures, it is difficult to arrange the cableway support points. If it is selected to slide along the width direction, the sliding distance of the hanging basket is 22m, the cableway disturbance deformation is small, and the cableway support points are easy to remove later. Comprehensive consideration, in order to ensure the safety of construction and the stability of the hanging basket, a flexible cableway hanging basket structure that slides along the width direction of the steel structure corridor is selected.

[0044] 1. Arrangement of hanging basket

[0045] The standard suspended basket working platform has three types of standard sections: 1.5m, 2.0m, and 2.5m. The length span of this project is 38.7m. Therefore, three 2.0m standard sections are selected to assemble a 6m standard ZLP-630 suspended basket, and a safety distance of 500mm is reserved between adjacent suspended baskets. A cableway is set on both sides of each suspended basket, so a total of 6 6.0m operating suspended baskets are set at the bottom of the steel structure corridor, and the suspended baskets near the tower are 100mm away from the tower structure edge.

[0046] 2. Design of fixed bracket of cableway

[0047] The cableway fixed bracket is welded into a "Y" shape using 120×80×5mm galvanized steel through processing. The main force-bearing rod of the cableway fixed bracket is welded to the outside of the lower chord at the bottom of the steel structure corridor, and the end of the oblique support rod is welded to the bottom of the lower chord at the bottom of the steel structure corridor. The two adjacent (only 500mm spacing) cableway fixed brackets are tied with a horizontal tie rod. The welding adopts a four-sided welding method, and the vertical welding adopts a segmented welding method. The length of each weld shall not be less than 100mm, and the weld height shall not be less than 5mm. After the cableway fixed bracket is welded, remove the welding slag, grind and clean it, and check the welding quality, slag inclusion, sand eyes, etc. After the cableway fixed bracket is welded, a 16mm thick steel plate is welded to the bottom of the cableway fixed bracket. The welding adopts a four-sided welding method, and the weld height shall not be less than 5mm. After the welding is completed, remove the welding slag and check the welding quality. If it meets the requirements, apply anti-rust paint.

[0048] 3. Design of flexible ropeway

[0049] Multiple groups of flexible cableways are arranged at the bottom of the steel structure corridor. Considering the safety of force, the cableway uses a cableway wire rope with a diameter of 30mm. The cableway wire rope is installed and tensioned. The wire rope is inserted through the 35mm diameter through hole of the steel plate of the fixed bracket of the cableway at one end. Before bending back, the wire rope protection steel ring is placed between the steel plate and the cableway wire rope. A buckle with a diameter of 28mm is used at the protection steel ring to tighten the wire ropes on both sides and lock them in the buckle. The first buckle, the second buckle, the third buckle and the fourth buckle are installed in sequence at intervals of 180mm. Between the third buckle 83 and the fourth buckle 84, a safety ring should be made for the cableway wire rope. After one end of the cableway wire rope is installed, install the other end of the same cableway wire rope, insert the other end of the cableway wire rope into the through hole of the steel plate of the cableway fixed corbel on the other side, put in the protective steel ring of the cableway wire rope, install the hand chain hoist on the steel keel at the bottom of the steel structure corridor, and then connect one end of the cableway wire rope to the hand chain hoist. Use the hand chain hoist to tension the cableway wire rope. When tensioning, the hoist should be tensioned until it can't be pulled anymore. After an interval of 30 minutes, tension it again. After the tensioning is completed, use the buckle to clamp the cableway wire ropes on both sides together, and tighten the buckle nut.

[0050] 4. Design of sliding device

[0051] The sliding device includes a movable pulley and a hanging basket lifting mechanism. The hanging basket lifting mechanism includes a hanging basket lifting wire rope. The hanging basket lifting wire rope is connected to the hanging basket. The movable pulley is installed on the flexible cableway. The movable pulley hook is tied to the hanging basket lifting wire rope. The hanging basket slides along the flexible cableway at the bottom of the steel structure corridor by manually pulling the flexible cableway.
