AI Technical Summary

Technical Problem

Conventional surface structures composed of cement-based and wooden members lack rigidity and strength, necessitating additional metal joists that increase floor height.

Method used

A surface structure comprising a wooden bottom surface material, wooden rib material connected to its upper surface, and a cement-based surface material connected to the wooden rib material, forming a rigid and load-bearing structure without the need for additional support beams.

Benefits of technology

The integrated wooden and cement-based structure enhances rigidity and load-bearing capacity, allowing for reduced floor height and improved stability, with enhanced connection methods ensuring firm bonding between components.

Abstract

To provide a face structure, a method for manufacturing the face structure, and a wooden member for the face structure that can reduce height of a story.SOLUTION: A face structure 20 is manufactured by pouring a cementitious material against a wooden formwork 21 for the face structure. The face structure 20 comprises: a wooden bottom face material 25; a wooden rib material 26 connected to an upper face 25a of the wooden bottom face material 25; and a cementitious face material 22 connected to an upper end of the wooden rib material 26 and provided with a space above the wooden bottom face material 25.SELECTED DRAWING: Figure 1
