specific Embodiment approach 1

[0013] Specific implementation mode one: combine Figure 1-Figure 4 Explain, the prestressed concrete single-slope double T-slab of the present embodiment, it 1, the prestressed concrete single-slope double T-slab, it comprises panel 1, two longitudinal rib beams 2, two end transverse ribs 3 and a plurality of spans Middle beam 4;

[0014] The two longitudinal rib beams 2 are plate-like structures arranged side by side. The bottom surfaces of the two longitudinal rib beams 2 are planes, the upper surfaces of the two longitudinal rib beams 2 are inclined planes, and the upper surfaces of the two longitudinal rib beams 2 are from the lower end to the A plurality of mid-span beams 4 are installed side by side at the high end, and an end beam 3 is installed at each end of the two longitudinal rib beams 2. The panel 1 is arranged parallel to the slope of the longitudinal rib beam 2 and installed on the end beams 3 and the mid-span beam. 4 on.

specific Embodiment approach 2

[0016] Specific implementation mode two: combination figure 1 and figure 2 Illustrate, the mid-span beam 4 of the present embodiment is mainly made up of triangular prism 4-1 and two right triangular pyramids 4-2, and the triangular end face of triangular prism 4-1 is connected with a right angle end face of triangular pyramid 4-2, and triangular pyramid The other right-angled end face of 4-2 is parallel to panel 1. With such setting, the connection is stable and reliable, which ensures the service strength of the prestressed concrete single-slope double-T slab and the strength of the roof constructed by lap joints. Others are the same as in the first embodiment.

Abstract

The invention discloses a prestressed concrete single-slope double-T plate, relates to a concrete single-slope double-T plate, and aims to solve the problem that the existing double-slope type prestressed concrete double-T plate affects the drainage effect of a roof or the use of a building is affected by the fact that leakage is unavoidably caused in indoor drainage. The prestressed concrete single-slope double-T plate comprises a panel, two longitudinal rib beams, two end part transverse beams and a plurality of midspan cross beams, wherein the two longitudinal rib beams are plate type structures arranged side by side; the bottom surfaces of the two longitudinal rib beams are planes; the upper surfaces of the two longitudinal rib beams are slopes; the multiple midspan cross beams are mounted on the upper surfaces of the two longitudinal rib beams from the lower ends to the higher ends side by side; each end part cross beam is mounted at each of two ends of the two longitudinal rib beams; the panel is parallel to the slopes of the longitudinal rib beams and is mounted on the end part cross beams and the midspan cross beams. The prestressed concrete single-slope double-T plate is used for forming a roof structure for finding a slope for a long-span structure.

Description

technical field [0001] The invention relates to a concrete single-slope double-T board. Belongs to the field of civil engineering. Background technique [0002] At present, the prestressed concrete double T slabs used for building roofs to realize structural slope finding are double-slope type, and the maximum mark span is 30m. If the building requires a large width and is composed of multi-span column nets, multiple sets of prestressed concrete double T-slabs with different sign spans must be arranged along the width of the building to form a roof structure. This often leads to the lowest point of the roof formed at the intersection of two adjacent prestressed concrete double T slabs in the width direction. The unavoidable leakage of drainage affects the use of buildings. Contents of the invention [0003] The present invention aims to solve the problem that the existing double-slope prestressed concrete double-T slab affects the roof drainage effect or affects the use...
