Description

Technical Field

[0001] The utility model relates to the field of building construction, in particular to a standardized channel between a tower crane material transfer cantilever platform and a building. Background Art

[0002] In the construction of buildings with a certain height, in order to improve the transportation efficiency of construction materials, a material transfer platform for receiving the materials lifted by the lifting machinery is usually set up on the periphery of the building. After the construction materials are lifted to the material transfer platform, they need to be manually transported to the building for a second time. In order to facilitate the manual secondary transportation of construction materials, a passage is usually built between the material transfer platform and the building floor for transportation carts and workers to pass through.

[0003] At present, most traditional channels use scaffolding between the material transfer platform and the building floor as a temporary material transfer channel or build a long-term channel with a stable structure between the material transfer platform and the building floor. These traditional channels have many defects. For example, the temporary channel is unstable and prone to safety hazards. The long-term channel construction is inefficient, time-consuming and material-consuming, and difficult to dismantle, making it impossible to rotate and use. Utility Model Content

[0004] The utility model aims to provide a standardized passage between a tower crane material transfer cantilever platform and a building, which is easy to assemble and disassemble, made of standard material specifications, can be used with the material transfer platform, and has good stability and safety.

[0005] The purpose of the utility model is achieved through the following technical scheme: it includes two cantilevered main beams arranged on the top surface of the building at a front and rear interval, the right end of the cantilevered main beam extends out of the top surface of the building, and a tower crane transfer platform is jointly erected on the top side of the extended end, an external scaffolding is arranged between the tower crane transfer platform and the top surface of the building, a material transfer channel is hinged on the tower crane transfer platform, the material transfer channel is flipped and erected on the top surface of the building, and the middle part is supported on the top of the external scaffolding.

[0006] Compared with the prior art, the advantages of the utility model are:

[0007] 1. Through the coordination of the tower crane transfer platform and the transfer channel hinged on the tower crane transfer platform, the transfer channel can be flipped and erected on the top surface of the building to facilitate the passage of transport carts and workers. When the tower crane transfer platform needs to be used in rotation, the transfer channel can be flipped and retracted above the tower crane transfer platform and installed to other places with the tower crane transfer platform, achieving the effect of fast and convenient turnover;

[0008] 2. By setting up movable joints and guardrail bases, the guardrail can be quickly installed and removed on the guardrail base through the movable joints, and through the rotation of the rod shaft and the positioning hole, the rod shaft drives the guardrail to flip over and surround the front and rear edges of the material transfer channel, ensuring the personal safety of workers during the secondary handling process; after the handling is completed, the guardrail can be flipped back to the steel bottom plate, reducing the longitudinal height of the material transfer channel, which is convenient for storage during the turnover of the material transfer channel.

[0018] The material transfer channel 5 includes a steel base plate 51 and a channel frame 52 arranged on the bottom side of the steel base plate 51. The steel base plate 51 extends left and right, and its right end is hinged to the tower crane material transfer platform 3. An L-shaped steel support 53 is fixed below the hinge of the tower crane material transfer platform 3, and the steel support 53 is supported on the bottom of the channel frame 52.

[0019] The building top surface 1 is the top surface of the building floor structure layer.

[0020] The cantilever main beam 2 is an I-beam, the specification of which is selected based on actual load calculation, and the I-beam is fixedly connected to the building top surface 1 by pre-embedded U-shaped steel bars.

[0021] The steel bottom plate 51 and the tower crane transfer platform 3 are hinged by installing heavy-duty thickened hinges.

[0022] The steel bottom plate 51 is preferably a patterned galvanized steel plate with a thickness of 3 mm;

[0023] The specification of the steel bottom plate 51 is preferably 1300 mm to 1350 mm, so that mainstream transport carts in the market can pass smoothly;

[0024] The channel skeleton 52 is formed by fixing a plurality of strip steel pipes, which are supported on the four sides and the middle of the steel bottom plate 51. The plurality of strip steel pipes in the middle are crisscrossed and connected with the strip steel pipes on the four sides to form a grid-like skeleton structure. The material of the strip square tube is preferably made of flat steel with a specification of 40*4mm.

[0025] The steel support 53 is an equilateral angle steel, and its specification is preferably 50mm*50mm.

[0026] The material transfer channel 5 also includes guardrail components 54 disposed on the front and rear sides of the top of the steel bottom plate 51;

[0027] The guardrail assembly 54 includes an inverted U-shaped guardrail 541, movable joints 542 provided at the bottom of the left and right legs of the guardrail 541, and a guardrail base 543 fixed on the steel bottom plate 51 and corresponding to the movable joints 542;
