Description

Technical Field

[0001] This invention relates to the field of space frame roof technology, specifically to a construction device and method for the full-span support installation of a large-span space frame roof. Background Technology

[0002] A space frame roof is a spatial mesh structure composed of members arranged along a certain curvature or plane, suitable for large-span buildings such as stadiums, theaters, and auditoriums. The installation method for flat-plate space frames must be considered in conjunction with the span, weight, and structural characteristics of the space frame. Space frame roofs are manufactured as members or assembled into small units in the factory, then transported to the site for assembly. Therefore, accurate member dimensions are required, and bolt hole deviations must not exceed allowable tolerances. During factory fabrication, the effects of temperature-induced expansion and contraction of members and camber-induced changes in spatial dimensions must also be considered. Due to its rational stress distribution, good overall rigidity, and strong earthquake resistance, and its flexible building layout, various installation methods can be broadly categorized into two types: one is direct high-altitude assembly, adapting to the functional needs of various large-span buildings; although the fabrication and installation are more complex and costly, this has not hindered its adoption and development under specific conditions.

[0003] Space frame houses come in various forms, with large-span space frame houses being one type. The installation of a large-span space frame roof requires supporting installation equipment. For example, Chinese patent CN102191866A discloses a construction device and method for removing the lower columns of a large-span space frame. This device includes a large-span space frame, a temporary support structure, a fixed structure, an installation device, and operating scaffolding. The large-span space frame includes a target removal support column, a pair of fixed support columns on both sides of the target removal support column, and a top surface of the space frame above the aforementioned support columns. The pair of fixed support columns includes a first fixed support column on one side of the target removal support column and a second fixed support column on the other side. The temporary support structure is located between the top surface of the space frame and the ground. The fixed structure is fixedly located below the top surface of the space frame. The installation device includes a truck crane and a pair of winches. The operating scaffolding is located on the bottom surface of the large-span space frame, surrounding the temporary support structure and extending upwards to below the top surface of the space frame. This invention effectively controls construction risks, enables the conversion of building functions, meets construction safety and schedule requirements, and reduces construction costs. While this patent enables the conversion of building functions, meets construction safety and schedule requirements, and reduces construction costs, it is inconvenient to control the position of the scaffolding. As a result, users can only control the height of the scaffolding parts and cannot adjust the rising position according to different scaffolding parts. Therefore, users need to use tools to retrieve them, which affects normal use. Summary of the Invention

[0004] To address the problems mentioned in the background art, the present invention aims to provide a construction device and method for supporting and installing a full-span scaffolding roof with a large span, which has the advantage of adjusting the rising position according to different full-span scaffolding parts, thus solving the problem that the support installation construction device cannot adjust the rising position according to different full-span scaffolding parts.

[0047] S1: The user first manually pulls the sliding sleeve 33, and then the sliding sleeve 33 controls the left and right movement of the part connector 4 through the sliding block 32 and the connecting rod 31. The user manually inserts the positioning sleeve 34 into the interior of the sliding block 32 from the bottom of the sliding sleeve 33, and then inserts the bottom of the positioning rod 35 through the interior of the sliding block 32, so that the bottom of the screw 36 extends into the interior of the positioning sleeve 34. The sliding block 32 is fixed by the positioning sleeve 34 and the positioning rod 35, the positioning sleeve 34 is fixed by the sliding block 32, and the part connector 4 is fixed by the positioning sleeve 34.

The part connecting plate 44 drives the part to move upward, so that the part rises to the user's hand and does not need to be picked up by the user with tools.

[0049] The working principle and usage process of this invention are as follows: In use, the user first manually pulls the sliding sleeve 33. The sliding sleeve 33 then controls the left and right movement of the component connector 4 via the sliding block 32 and connecting rod 31. The user manually inserts the positioning sleeve 34 from the bottom of the sliding sleeve 33 into the interior of the sliding block 32. Then, the bottom of the positioning rod 35 penetrates into the interior of the sliding block 32, allowing the bottom of the screw 36 to extend into the interior of the positioning sleeve 34. The positioning sleeve 34 and positioning rod 35 fix the sliding block 32, and the sliding block 32 fixes the positioning sleeve 34. The positioning sleeve 34 then secures the component connector 4. Connector 4 is fixed in place. Then, the user connects the part connecting plate 44 to the part connecting plate 44, and then drives the motor 21. The motor 21 drives the threaded rod 22 to rotate. The threaded rod 22 drives the threaded sleeve 23 to move the connecting block 24 upward. The connecting block 24 drives the transmission mechanism 2 to move upward. The transmission mechanism 2 drives the positioning block 41 to move upward. The positioning block 41 drives the part connecting plate 44 to move upward through the first connecting plate 42 and the second connecting plate 43. The part connecting plate 44 drives the part upward, so that the part rises to the user's hand and does not need to be picked up with tools.
