Description

TECHNICAL FIELD

[0001] The utility model relates to the technical field of board material, concretely to a novel UHPC waffle trestle board. BACKGROUND

[0002] UHPC waffle trestle board is a waffle (honeycomb) structure trestle board made of ultra-high performance concrete (UHPC). UHPC has extremely high strength, durability and corrosion resistance, making the trestle superior to conventional materials in terms of carrying capacity and service life. However, during the later use of UHPC waffle trestle board, cracks are prone to occur, and the cracks also expand rapidly, increase in number, and reduce the structural strength and toughness, making brittle fracture more likely to occur, which affects the durability and service life. Moreover, when high-strength steel wire mesh is laid inside the UHPC waffle trestle board, the laying method cannot ensure that the position of the high-strength steel wire mesh does not deviate or sink, which directly affects the later processing of the internal filler of the UHPC waffle trestle board, thereby reducing the efficiency of the later forming of the UHPC waffle trestle board and affecting the final quality and durability of the UHPC waffle trestle board.

[0003] Therefore, it is necessary to develop a new type of UHPC waffle trestle board. SUMMARY
