Abstract

The utility model discloses a large-span prestressed concrete double T plate which comprises two vertical beams integrally prefabricated, a reinforcing rib and a top plate. The cross section is basically double T-shaped, the top plate is fixedly connected onto the upper end faces of the two beams, and the connection position of the beams and the top plate are in triangular fixed connection to form two plate wings and ensure that the root portions of the plate wings increase required strength due to the fact that the plate wings are increased and generate moment. The reinforcing rib is fixedly connected onto two plates in the middle of span length of the double T plate, the upper end face of the rib is fixedly connected with the lower end face of the top plate, and the reinforcing rib is semicircular and extends to the plate wings to effectively support the top plate. The large-span prestressed concrete double T plate is capable of resolving the problem that the prestressed concrete double T plate with top plate width larger than 3 meters and span larger than 20meters is insufficient in rigidity and strength.

Description

The large span prestressed concrete T plate

Technical field

The utility model relates to building material technical field, especially relates to a kind of large span prestressed concrete T plate.

Background technology

Present working shop of enterprise roofing because with prestressed concrete double T plate prefabricated component saving of labor, save time, easy construction, the traditional man-like shelf structure of replacing in the sixth of the twelve Earthly Branches adds tile and roof concrete cast-in-situ.Along with the development of enterprise and builing industry, widen increasing for width, the span requirement of prestressed concrete double T plate.The structure of traditional prestressed concrete double T plate, can only be applicable to the concrete precast element that the top board width is not more than 2.4 meters, can not be used for top board width more than 3 meters, the prestressed concrete double T plate of span more than 20 meters, have rigidity and strength deficiency, can not satisfy the Building technology requirement.

The utility model content

The utility model proposes a kind of large span prestressed concrete T plate for the deficiency that above prior art exists, and can solve rigidity and the strength deficiency of top board width more than 3 meters, the prestressed concrete double T plate of span more than 20 meters.

To achieve these goals, the utility model large span prestressed concrete T plate adopts following technical scheme: comprise two integral prefabricated vertical beams, ribs and top board, the cross section is double-T substantially, described top board is fixed on the upper surface of two beams, beam and top board joining place are that triangle is affixed, form the two plate wings, guarantee plate wing root section and produced the required intensity of moment of flexure increase because cantilever strengthens, described ribs, be fixed on two middle beams of T plate span length, the upper surface of ribs and the lower surface of top board are affixed, the ribs semicircular in shape, extend to the plate wing, top board is produced effectively support.

The beneficial effect of the utility model large span prestressed concrete T plate: because the setting of ribs, top board is effectively supported, prestressed concrete double T plate rigidity and strength character have been strengthened, solve rigidity and the intensity of top board width more than 3 meters, the prestressed concrete double T plate of span more than 20 meters, reached T plate structural performance loading test requirement.

Description of drawings

Fig. 1 is perspective view of the present utility model;

Fig. 2 is plan structure schematic diagram of the present utility model.

Among the figure: beam (1), ribs (2), the plate wing (3), top board (4), suspension ring (5).

The specific embodiment

Below in conjunction with the enforcement of accompanying drawing to the utility model large span prestressed concrete T plate, be described in further detail.

The large span prestressed concrete T plate is integral prefabricated, comprises two vertical beams (1), ribs (2) and top board (4), and the cross section is double-T substantially.Top board (4) is fixed on the upper surface of Liang Tiaoliang (1), beam (1) is that triangle is affixed with top board (4) joining place, form the two plate wings (3), guarantee the plate wing (3) root and produced the required intensity of moment of flexure increase because cantilever strengthens, on top board (4) face four suspension ring (5) are arranged, crane during for carrying; Ribs (2) is fixed on the middle Liang Tiaoliang (1) of T plate span length, the upper surface of ribs (2) and the lower surface of top board are affixed, ribs (2) semicircular in shape extends to the plate wing (3), and ribs (2) is reinforced concrete structure.

Claims

1. large span prestressed concrete T plate, comprise integral prefabricated two vertical beams (1), ribs (2) and top board (4), the cross section is double-T substantially, it is characterized in that: top board (4) is fixed on the upper surface of Liang Tiaoliang (1), beam (1) is that triangle is affixed with top board (4) joining place, form the two plate wings (3), ribs (2) is fixed on the middle Liang Tiaoliang (1) of T plate span length, the upper surface of ribs (2) and the lower surface of top board are affixed, ribs (2) semicircular in shape extends to the plate wing (3).
