Embodiment Construction

[0022] In order to make the technical means, creative features, goals and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0023] see figure 1 , shown in the figure is a prefabricated ultra-high performance concrete flue slab structure, including the bottom plate 100 and the left and right side plates 200, 300, the bottom plate 100 and the left and right side plates 200, 300 are enclosed to form a " "凵" font structure. The bottom plate 100 and the left and right side plates 200, 300 are prefabricated and integrally molded with ultra-high-performance concrete in the factory, so that the production of flue plates of various sizes can be realized, and the product quality is obviously better than that of cast-in-place.

[0024] The base plate 100 is provided with several ventilation holes (not shown in the figure). In this embodiment, the plurality of ventilation holes...

Abstract

The invention discloses a prefabricated fabricated ultra-high-performance concrete flue plate structure. The structure comprises a bottom plate, a left side plate and a right side plate, and an inversed-U-shaped structure is defined by the bottom plate, the left side plate and the right side plate; and a plurality of vent holes are formed in the bottom plate, a plurality of fastening pieces fixedly connected with a flue top plate are arranged at the upper edges of the left side plate and the right side plate, and the bottom plate, the left side plate and the right side plate are prefabricated and integrally formed through ultra-high-performance concrete. The prefabricated fabricated ultra-high-performance concrete flue plate structure has the beneficial effects that a factory fabrication mode is adopted, production of flue plates of various sizes can be achieved, and the factory fabrication mode is obviously superior to a cast-in-place mode in product quality; and by adoption of an on-site splicing mode, the working procedures such as on-site formwork erecting, pouring, curing and formwork removal are omitted, and construction efficiency is greatly improved.

Description

technical field [0001] The invention relates to the technical field of flue slabs in tunnels, in particular to a prefabricated assembly type ultra-high performance concrete flue slab structure. Background technique [0002] In subways and other tunnels (hereinafter collectively referred to as "tunnels"), flue panels are mainly used to ensure the ventilation inside the tunnel and the smooth discharge of high-temperature smoke in the event of a fire. It is an extremely important structure in the tunnel. However, most of the current flue slabs are prepared by cast-in-place concrete. Due to the narrow space inside the tunnel, it is extremely difficult to formwork, pour and remove the formwork. Therefore, the construction efficiency is low and the quality is often not satisfactory. However, most of the current prefabricated flue panels are made of light materials such as glass fiber reinforced plastics and aluminum alloys, which will generate relatively large wind pressure during...
