Solution Overview
Problem
Existing building structures face challenges in easy and precise assembly due to the use of heavy steel materials and unstable suspended units that can collide with already assembled units during construction.
Innovation Solution

Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Strength
If heavy shaped steels or steel pipes are used for lattice beams and welding is employed to assemble short steel materials, then structural strength is improved, but assembling time increases and assembling precision deteriorates
Solution Approach 1:
The lattice beam is divided into multiple short steel materials that are assembled together. By using standardized connection structures at the joints, the segmentation enables modular assembly while maintaining structural integrity, resolving the contradiction between using heavy materials for strength and the time-consuming nature of assembling them
Solution Approach 2:
Connection structures are pre-formed with standardized configurations before the actual lattice beam assembly. This preliminary preparation of connection details allows for faster on-site assembly by eliminating the need for complex field welding operations, thus reducing assembling time while maintaining strength
2Strength
If heavy shaped steels or steel pipes are used for lattice beams and welding is employed to assemble short steel materials, then structural strength is improved, but assembling precision deteriorates
Solution Approach 1:
The connection method is changed from welding to a mechanical connection system with standardized geometries and tolerances. This parameter change in the joining process enables more consistent and precise alignment of steel materials, improving assembling precision while maintaining the required structural strength through optimized connection design
3Ease of operation
If units are suspended with wires for assembly, then assembly flexibility is improved, but stability deteriorates causing units to collide with already joined units
Solution Approach 1:
A guide structure is introduced as an intermediary element between the suspended unit and the already joined units. This guide structure provides physical constraints that prevent lateral movement and rotation of the suspended unit during assembly, eliminating collisions while preserving the flexibility of wire suspension for positioning

AI summary
A building structure that can be assembled easily with high assembling precision is provided.The building structure of the present invention is a building structure for transmitting a load on a roof to a post, and includes a unit (10) joined to a post (20). The unit includes three or more first beams arranged in parallel in one direction and three or more second beams arranged in parallel in another direction intersecting the one direction. Each first beam and each second beam has a truss structure. In a section where the first beam intersects the second beam, an upper chord of the first beam is disposed on an upper chord of the second beam and is joined to the upper chord of the second beam via a joining member, using a fastener. In the section where the first beam intersects the second beam, a lower chord of the first beam is disposed on a lower chord of the second beam and is joined to the lower chord of the second beam via a joining member, using a fastener.
