[0038] Beneficial effects:

[0039] (1) The present invention is used to replace manual loading and unloading of materials. Compared with traditional manual loading and unloading of materials, it not only avoids oblique pulling and lifting, high-altitude throwing, and reduces the incidence of safety accidents, but also saves manpower, reduces the labor intensity of workers, saves time, increases speed, shortens construction period, and reduces the direct cost of the project, thereby achieving the purpose of safe operation, cost saving, improved work efficiency, and increased benefits.

[0040] (2) The transport vehicle of the present invention can meet the requirements of both indoor horizontal transportation and horizontal transportation on an outdoor cantilever through the cooperation of ball bearings and double-track C-shaped steel. When transporting horizontally on an outdoor cantilever, the container in the vehicle can be placed directly below the top of the crane hook, thereby solving the problems of oblique pulling, slanting lifting and high-altitude throwing, and meeting the technical requirements of Article 3.0.15 of the "General Provisions for Hoisting and Lifting" in the "Technical Specifications for Safety of Hoisting and Lifting in Construction": "The hoisted components should be ensured to be directly below the top of the crane boom, and oblique pulling and slanting lifting are strictly prohibited."

[0041] (3) The present invention is applicable not only to frame column group structures, but also to frame-shear wall structures, thereby solving the technical problems of oblique stays and oblique suspensions existing in buildings of the two structures.

[0042] (4) In the present invention, reinforcing plate I, reinforcing plate II and steel strip are added to the C-shaped steel, thereby increasing the shear, bending and torsional strength of the double-track C-shaped steel.

[0043] (5) The transport structure applicable to the frame-shear wall structure of the present invention includes a spacing adjustment component and a positioning sleeve, so that positioning is simple and easy to operate during the installation of the double-track C-shaped steel.

[0044] (6) The length of the support column applicable to the frame-shear wall structure in the present invention is adjustable and can be applied to different heights; and the upper end of the support column is not fixedly connected to the floor slab above the floor, which makes installation and disassembly easier while ensuring the anti-overturning and stability of the transportation system.

[0045] (7) The rail transport wheel applicable to the frame-shear wall structure of the present invention is used to move the positions of two C-shaped steel rails after the spacing has been adjusted, thereby making the transportation of the double-track C-shaped steel more convenient during the assembly and disassembly process.

[0046] (8) The double-track C-shaped steel of the present invention limits the vehicle body structure, and the structure is stable and safe. Not only can people walk safely on the double-track C-shaped steel indoors, but they can also walk safely on the long arm of the outdoor cantilevered long arm suspended track.

[0047] (9) The transport vehicle of the present invention is provided with bottom columns for supporting the vehicle box, so that the vehicle box is separated from the upper surface of the double-track C-shaped steel, thereby avoiding friction between the vehicle box and the double-track C-shaped steel; at the same time, when used in a frame column group structure, the width of the designed vehicle box can be increased, thereby increasing the capacity of the vehicle box. However, when used in a frame-shear wall structure, the width of the vehicle box is limited due to the limitation of the supporting columns around the double-track C-shaped steel, so the capacity of the vehicle box can be increased by increasing the length of the designed vehicle box.

[0095] The width of the vehicle box of the transport vehicle 10 is smaller than the clear distance between each set of support pillars 32 (i.e., the shortest distance between the outer surfaces of each set of support pillars);

[0096] The C-shaped steel fixing assembly II includes: more than two spacing adjustment assemblies, more than two sets of positioning sleeves 38 and more than two sets of support columns 32; the more than two spacing adjustment assemblies are used to adjust the distance between two C-shaped steel rails when installing the C-shaped steel rails; the more than two sets of support columns 32 are used to position the double-track C-shaped steel 9 at a height of H from the floor 14; the more than two sets of positioning sleeves 38 are mainly used to position the support columns 32 when installing the support columns 32;

[0097] More than two spacing adjustment components are arranged at intervals, and each spacing adjustment component includes two ear plates 39, a spacing adjustment shaft 40 and four nuts 41; the two ear plates 39 of each spacing adjustment component are welded to the bottom of the two C-shaped steel rails relative to each other, and each ear plate 39 is located below the web of the corresponding C-shaped steel rail; both ends of each spacing adjustment shaft 40 are processed with external threads, and each spacing adjustment shaft 40 is arranged through two opposite ear plates; two nuts 41 are respectively installed at both ends of each ear plate 39, and the distance between the two opposite ear plates 39 is adjusted by adjusting the position of the nuts 41 on both sides of each ear plate 39 on the spacing adjustment shaft 40, thereby adjusting the distance between the two C-shaped steel rails;

[0098] Rail transport wheels 42 are also installed at both ends of each spacing adjustment shaft 40. The rail transport wheels 42 are rubber wheels for driving the movement of the two C-shaped steel rails, thereby making the transportation of the double-track C-shaped steel 9 more convenient during assembly and disassembly.

[0099] Two or more groups of positioning sleeves 38 are arranged at equal intervals, and each group of positioning sleeves 38 includes two positioning sleeves 38 arranged opposite to each other. Each positioning sleeve 38 is a channel steel section, and the two positioning sleeves 38 are installed one by one on the outer side of the webs of two C-shaped steel rails in the room. The notch of each positioning sleeve 38 is opposite to the C-shaped opening of the corresponding C-shaped steel rail, and the web of each positioning sleeve 38 is welded to the web of the corresponding C-shaped steel rail. The upper wing plate of each positioning sleeve 38 is located in the same plane as the upper wing plate of the C-shaped steel rail; coaxial through holes N are processed on the two wing plates of each positioning sleeve 38;

[0104] Working principle: In the frame-shear wall structure, the double-track C-shaped steel 9 is lifted and fixed to a height of H from the floor 14 by the support column 32 indoors, and extends to the outdoors; H is greater than or equal to the height of the lower part of the window opening 30 from the floor 14 (i.e., the height of the shear wall 31 at the lower part of the window opening 30 on the floor 14), and H is greater than the height of the balcony enclosure 10; the transport vehicle 10 reciprocates along the double-track C-shaped steel 9, and when the transport vehicle 10 is suspended on the double-track C-shaped steel 9 outdoors, the container 19 in the transport vehicle 10 can be placed directly under the hook 12;

[0105] When transporting building materials to each floor, firstly, various building materials and equipment to be installed on each floor of the high-rise building are loaded in containers 19, and then the containers 19 are lifted vertically upward or downward to each floor by tower cranes 11, and vertically placed on transport vehicles 10 on double-track C-shaped steels 9 suspended outdoors on each floor, and finally the materials are transported horizontally along the double-track C-shaped steels 9 to the corresponding floors for unloading;

[0106] When transporting waste materials from each floor to the ground, firstly, each floor loads the disassembled waste materials into a container 19, puts the container 19 into a transport vehicle 10, and then transports it along the double-track C-shaped steel 9 to the outer end of the suspended double-track C-shaped steel 9 outdoors, and finally lifts the container 19 to the ground for unloading by a vertically lifting tower crane 11;

[0107] The above technical solution solves the problems of oblique pulling, oblique lifting and throwing objects from high altitudes, and meets the technical requirements of Article 3.0.15 of the "General Provisions for Lifting and Hoisting" in the "Technical Specifications for Safety of Lifting and Hoisting in Construction": "The lifted components should be ensured to be directly below the top of the crane boom, and oblique pulling and oblique lifting are strictly prohibited."
