Embodiment 1

[0023] The present invention proposes a kind of construction method of prestressed concrete double T plate, comprises the steps:

[0024] S1: First of all, the surface of the prestressed double T plate needs to be partially thinned at the part where the laminated layer needs to be superimposed, and then the surface of the thinned part is roughened to make the surface rough;

[0025] S2: Through calculation, the laminated layer is manufactured, and then the laminated layer is attached to the roughened surface, so that the overall performance of the prestressed double T plate can be improved through the laminated layer member, and the double T plate can be satisfied. load;

[0026] S3: A plurality of connecting ribs are welded on the side of the superimposed layer member, and the other end of the connecting rib is inserted into the inside of the double T plate, and the connecting rib is fixed on the double T plate by cement pouring, so as to achieve the The purpose of structura...

Abstract

The invention discloses a construction method of a prestressed concrete double T plate. The construction method includes the steps: performing local thinning on the portion, requiring for laminating alaminated layer, on the surface of the prestressed double T plate, and then roughening the surface of the thinned portion to roughen the surface of the thinned portion; through calculation, preparinga laminated layer, and then attaching the laminated layer to the roughened surface, so as to improve the overall performance of the prestressed double T plate through the laminated layer member; andfixing connecting ribs on the double T plate by cement pouring, putting spacing ribs above the double T plate, fixedly connecting two ends of the spacing ribs to the double T plate, reinforcing the laminated layer member to prevent deformation of the laminated layer member, and reinforcing the load of the laminated layer member. The construction method of a prestressed concrete double T plate hasthe advantages of being reasonable in structure, being convenient for operation, attaching the laminated layer to the roughened surface through calculation so as to enable the laminating method of theprestressed double T plate to be flexible, thus being wide in the practical application range.

Description

technical field [0001] The invention relates to the technical field of concrete double T slabs, in particular to a construction method for prestressed concrete double T slabs. Background technique [0002] Prestressed concrete double T-slab is a prefabricated component with beams and slabs integrated into one. When it is used for structural floors or roofs, it should provide sufficient in-plane rigidity through reliable connections between adjacent slabs to ensure the level of floor or roof transmission. force, especially earthquake force. The current domestic codes do not provide for the calculation of the connection, and the national standard atlas has no reference for the connection of adjacent double T-slabs with two or more spans and no walls in the middle. But now in the process of making concrete double T slabs, the setting of laminated layers is not flexible and the operation is troublesome. In the process of practical application, it has certain limitations. In ord...
