Arched cavity fluid flowing floor slab, manufacturing method and flowing pipe

Abstract

The invention relates to the field of buildings, and discloses an arch-shaped cavity fluid flowing floor slab, an arc-shaped groove is formed in the bottom surface of the floor slab, a groove enabling the groove to be communicated with the outer side of the floor slab is formed in the side part of the arc-shaped groove, the depth of the groove is close to that of the groove, and a supporting surface is arranged at the bottom of the floor slab. A groove is formed in the floor, the floor and the supporting face form a box body structure, a cavity and a pipeline are arranged in the box body structure, two arched beam plates which are arranged in a crossed mode are arranged in the groove, the bending degree of the arched beam plates is consistent with the radian of the groove, and beam feet at the two ends of the arched beam plates are fixedly connected with the supporting face. The concrete consumption is reduced, the bearing capacity of the whole structure is improved, reinforcing steel bars do not need to be embedded into the floor slab for reinforcement, the flowing pipe formed by arranging the floor slabs has no obvious sudden expansion and sudden shrinkage structures, local pressure loss in the flowing process of airflow or water flow is effectively reduced, and the efficiency of fluid flowing work such as smoke exhaust, ventilation and water drainage is remarkably improved.

Description

technical field [0001] The invention relates to the field of construction, in particular to an arched cavity fluid flow floor, a manufacturing method and a flow pipe. Background technique [0002] With the continuous improvement of social progress and productivity level and the development of personalization, people pay more and more attention to the quality of living, and put forward higher requirements for buildings, hoping for better comfort and freedom, which is a challenge for structural designers That is, lighter weight, more reasonable floor height and better mechanical properties, etc., to meet customers' expectations of obtaining the best benefits and functions in a limited building space. [0003] In ordinary reinforced concrete structures, the dead weight of the floor is about 30%~40% of the total dead weight. In reinforced concrete high-rise structures, the dead weight of the floor is about 50%~60% of the total dead weight, while in large-span buildings In the m...

Problems solved by technology

[0004] Existing cavity floor slabs, for example, the patent number is: 202110869646.3 patent of invention discloses the scheme "a multifunctional cavity floor, the cavity floor includes a plurality of cavity floors combined with each other, the cavity There are single or multiple multi-functional cavities inside the floor. When the inside of the cavity floor is a single cavity, there are openings for connection around the floor. Multiple single-cavity floors are connected to each other through openings to form a flue; When there are multiple cavities inside the cavity floor, the cavities in the cavity floor are connected to each other by setting through holes between the beams to form a flue.” The flue structure of the above scheme has obvious sudden expansion and contraction structures , when the flue gas flows in the flue, the air flow pressure will be lost due to the change of the flue volume, the energy attenuation phenomenon is serious, and it is easy to cause the exhaust and ventilation costs to be too high, and it is difficult to meet the low-carbon requirements
