Problems solved by technology

[0002] Large-span prestressed concrete beams and slabs are used in frame structures. At present, there is no matching structural system, so they cannot be used. The cost of the proposed frame beams is also relatively high. The template is cumbersome and expensive, and quite a few experts questioned that it is unreliable, and the fixed frame distance of 5 meters, 7.5 meters, and 9.9 meters must be fixed for the 2.4-meter-wide plate-column network, which does not meet the corresponding process requirements.

Embodiment Construction

[0013] As shown in Figure 1: 1 is the column; 2 is the corbel beam on the column; 3 is the large-span prestressed double T plate with one flange removed; 4 is the bending steel bar on the upper part of the double T plate.

[0014] The frame column 1 and the corbel 2 on the column are built by the conventional method, and two double T-plates 3 and double ribs with corresponding flanges removed are combined and arranged on the corbels of the frame column 1 at both ends, and the bending reinforcement 4 on the plate is connected with The column reinforcement is connected, the lower embedded part is connected with the upper embedded part of the corbel beam, or the double T-plate end mustache reinforcement is connected with the column reinforcement, and a second pouring layer is made on the top to form a frame structure.

[0015] As shown in Figure 2, 1 is the column; 2 is the corbel beam on the column; 3 is the large-span prestressed single T plate; 4 is the bending steel bar on the...

Abstract

Provided are a prestressed concrete beam plate with the upper portion provided with flexural steel bars and a frame structure system. The flexural steel bars on the upper portion of the large-span concrete beam plate are connected with a column, and accordingly a large-span plate rib has the effect of a frame beam to form a frame structure.

Description

[0001] Technical field: building materials field Background technique [0002] Large-span prestressed concrete beams and slabs are used in frame structures. At present, there is no matching structural system, so they cannot be used. The cost of the proposed frame beams is also relatively high. The template is cumbersome and expensive, and quite a few experts questioned that it is unreliable, and the fixed frame spacing of 5 meters, 7.5 meters, and 9.9 meters must be fixed for the 2.4-meter-wide plate-column network, which does not meet the corresponding process requirements. Contents of the invention [0003] The invention provides a large-span prestressed concrete beam slab with bending steel bars on the upper part and its frame structure system to solve the above disadvantages. A large-span prestressed concrete girder slab with bending steel bars on the upper part includes double T slabs, single T girder slabs, channel slabs, swallow slabs, rectangular beams, bridge slabs,...
