Problems solved by technology

Because the height of the prefabricated prestressed channel slab structure is higher than that of the ordinary beam slab structure and the infinite floor structure, the floor height of the channel slab structure is higher
If it is used in the basement structure, it will increase the excavation of the basement foundation and affect the structural economy.

Embodiment Construction

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments, so that those skilled in the art can understand the present invention.

[0018] A prestressed trough plate with ventilation holes in the web, comprising two webs 1, a wing 2 and a concrete pouring layer 3 covering the tops of the web 1 and the wing 2, the web 1 is located on both sides of the wing 2 bottom of the end. It is characterized in that a plurality of stirrups 11 and a plurality of web prestressed longitudinal tendons 13 are arranged inside the web 1 . The stirrup 11 is located in the middle of the web 1 . The plane where the steel bars on both sides of the stirrup 11 are located is parallel to the axial cross-section of the web 1 . The web prestressed longitudinal reinforcement 13 is located on the inner side of the steel bars on both sides of the stirrup 11 . The two ends of stirrup 11 exceed the top 15cm of wing plate 2. The upper...

Abstract

The invention relates to the technical field of underground air-raid shelters, in particular to a prestressed trough plate with webs provided with vent holes. The prestressed trough plate comprises the webs, a wing plate and a concrete poured layer covering the tops of the webs and the top of the wing plate. The vent holes are formed in the webs. Reinforcing components are arranged around the vent holes. According to the prestressed trough plate, rectangles are reserved in the webs of the trough plate for forming the vent holes, and various vent pipelines, fire prevention water hoses and heating pipelines of buildings pass through the vent holes, so that the storey height of equipment is decreased, the storey height of the trough plate structure is decreased, and the economical efficiency is improved. In addition, the reinforcing components are arranged around the vent holes, so that the structure bearing capacity is ensured.

Description

technical field [0001] The invention relates to the technical field of civil engineering, in particular to a prestressed grooved plate with ventilation holes on the web. Background technique [0002] At present, the prestressed concrete channel slab is a prefabricated reinforced concrete bearing member combined with a beam and a slab, which consists of a wide wing plate and two narrow and high webs. Prestressed concrete channel slabs have good structural mechanical properties, clear force transmission levels, and simple geometric shapes. They are economical load-bearing components that can be made into large spans, large loads, and large coverage areas. Applications. Because the height of the prefabricated prestressed channel slab structure is higher than that of the ordinary beam slab structure and the infinite floor structure, the floor height of the channel slab structure is higher. If it is used in the basement structure, it will increase the excavation volume of the b...
