Abstract
The invention discloses a pre-stressed reinforced concrete bidirectional ribbed slab (double-T folded plate), comprising two vertical beams and a top plate, wherein the top plate comprises a horizontal plate and two inclined plates; the two vertical beams are positioned on both ends of the horizontal plate respectively; one inclined plate is connected to both ends of the horizontal plate respectively; both inclined plate incline upwards and are symmetrical to each other; an arc transition structure is adopted at a connection part between each vertical beam and the top plate; a rib is arranged between the two vertical beams; and the upper end face of the rib is fixedly connected with the lower end face of the horizontal plate. The folded plate provided by the invention is more beneficial to roof drainage, avoids the possibility of roof ponding, enhances the roof waterproof effect, and has excellent thermal-insulation and sound-insulation effects.
Description
Technical field
The present invention relates to a kind of prefabricated component of constructional materials, relate in particular to a kind of prestressed reinforcement concrete double T flap.
Background technology
At present; On the Industrial and Civil Engineering; Long-span roofing structure particularly, the prestressed concrete roof panel that adopts usually is grooved roof panel, two-way ribbed floor (double T plate), ship type roof panel etc., these large roof slabs are because span is big, application surface is than extensively being used widely.But,, the function of use of building itself, building costs economical all remained and improves because there are some defectives in these large roof slabs self.Mainly there is the problem of the following aspects in existing large roof slab commonly used: 1, owing to receive the standard-required of rigidity and intensity, the width maximum of monolithic roof panel can be accomplished 2.4 meters, and every projection area coverage is restricted.2, the restriction of individual plates projected area causes too high.3, because the mechanism form of roof panel self after the roof panel installation, is a flat roof deck on the roofing basically, be unfavorable for water-proof drainage, the ponding seepage influences the normal use of structure easily.4, the heat preservation and soundproof effect is not ideal enough.
Summary of the invention
To the problem that above-mentioned prior art exists, the object of the invention is to provide prestressed reinforcement concrete double T flap a kind of simple in structure, reasonable in design; Help roof drainage more; Avoid the possibility of roof ponding, improved the roof waterproof effect, and had good heat preservation and soundproof effect.
Technical scheme of the present invention is: a kind of prestressed reinforcement concrete double T flap, comprise two vertical beams and top board, and said top board comprises level board and hang plate; Said two vertical beams lay respectively at the two ends of level board; The two ends of said level board also respectively connect a hang plate, and two blocks of hang plates all are inclined upwardly and symmetrically, the arc transition structure is adopted in said vertical beam and top board junction; Article two, also be provided with rib between the vertical beam, the upper surface of said rib is fixedly connected with the lower surface of level board.
As preferably, said rib inside is provided with stiffener.
As preferably, said top board is a double-decker, and its lower floor is the concrete structure identical with vertical beam, and its upper strata is the haydite concrete structure.
The invention has the beneficial effects as follows: 1. the arc transition structure is adopted in vertical beam and top board junction; Rib is set between the vertical beam; Thereby increased whole rigidity and intensity, guaranteed quality effectively, also satisfied and produced bigger width requirement of products; Span is big, and supporting capacity is high, structural performance is more reliable.2. utilize the combination of level board and vertical panel, make roofing become stupefied shape, help roof drainage more, avoided the possibility of roof ponding, improved the waterproof effect of roofing.3. compare with the roof girder plate body system of identical span, alleviated dead load, saved steel.4. the present invention has wide range of applications, and being specially adapted to span is greatly roof structure.5. the haydite concrete structure is adopted on the top board upper strata, because haydite concrete includes the space, light specific gravity has the heat preservation and soundproof effect, and has good compressive strength, can satisfy the intensity and the rigidity requirement of building operations.

The specific embodiment
As one embodiment of the present invention, like Fig. 1, Fig. 2 and shown in Figure 3, a kind of prestressed reinforcement concrete double T flap; Comprise two vertical beams 1 and top board, said top board comprises level board 2 and hang plate 3, and said two vertical beams 1 lay respectively at the two ends of level board 2; The two ends of said level board 2 also respectively connect a hang plate 3; Two blocks of hang plates 3 all are inclined upwardly and symmetrically, said vertical beam 1 adopts the arc transition structure with the top board junction, also is provided with rib 4 between two vertical beams 1; Said rib 4 inside are provided with stiffener, and the upper surface of said rib 4 is fixedly connected with the lower surface of level board 2.Said top board is a double-decker, and its lower floor is the concrete structure identical with vertical beam 1, and its upper strata is the haydite concrete structure.
Claims (3)
