Abstract
The invention provides a large-span prestress bearing reinforced concrete double-T plate. The section of the large-span prestress bearing reinforced concrete double-T plate is in a double-T shape, and the large-span prestress bearing reinforced concrete double-T plate is formed by first rib plates, second rib plates, vertical beams, plate wings, a top plate and lifting rings. The vertical beams are fixedly connected below the top plate, and join positions are in triangular shape. The first rib plates are fixedly connected below the plate wings, and the end faces of the inner sides of the first rib plates are fixedly connected with the outer end faces of the vertical beams of both sides. The second rib plates are fixedly connected between the two vertical beams in a reinforcing steel manner. The bearing double-T plate can be used for constructing column-free buildings. The width and the height of T rib is enlarged on the basis of a conventional double-T plate, tension data is changed, fixed-point manufacture is carried out on selected stress material according to the design, and the technology of the large-span prestress bearing reinforced concrete double-T plate belongs to domestic advanced technology.
Description
Technical field
The present invention relates to steel concrete product, especially a kind of large-span prestressed load-bearing reinforcement concrete double T plate.
Background technology
T plate has good structural mechanical property, clear and definite power transmission level, succinct geometry, is a kind of large span, large area coverage with both economical bearing carrier of can be made into.In later stage the 1950's, T plate develops to some extent in countries in the world.China to start roofing for factory and superstructure from 1958.The sixties, the U.S. generally adopted, and became and built single-layer multiple-span industrial premises and multilayer is public, the common building component of civilian construction.The states such as Canada, Germany, Finland, Britain, Japan, Poland, Romania also all successively adopt T plate, and Germany also has the complete special equipment making T plate.In individual layer, multilayer and highrise building, T plate can directly be shelved on framework, beam or load bearing wall, as floor or roof structure.In single storey industry workshop, T plate is used as roof panel, can laterally be held on joist or load bearing wall, also can longitudinally be held on roof truss beam.Because T plate is suitable for comparatively large span, factory building can select larger span or post net, so as to obtaining good techno-economic effect.The multiplex compressive strength of reinforcement concrete double T plate is that 30 ~ 40 MPas are concrete prefabricated.Prestressing force T plate commonly uses the lightweight precast concrete that compressive strength is 40 ~ 50 MPa concrete or 40 MPas.Prestressed reinforcement can use high tensile steel wire, steel strand, low-carbon (LC) cold drawn wire and indented bars.
Tradition T plate be one be derived from large span, first open send out, prestressed concrete members, be for build large-span industrial building, warehouse, exhibition room etc. without post build product.But its application is confined to roof, band arch.And span is not high.
Summary of the invention
The present invention will solve the problem that traditional double T span of slab is little, load-bearing is low.
For solving the problems of the technologies described above, the technical solution used in the present invention is: a kind of large-span prestressed load-bearing reinforcement concrete double T plate, and its cross section is double-T, is made up of the first floor 1, second floor 2, vertical beam 3, the plate wing 4, top board 5 and suspension ring 6; Vertical beam 3 is fixedly connected on below top board 5, joining place is triangle, first floor 1 is fixedly connected on below the plate wing 4, and the first floor 1 inner side end is fixedly connected with both sides vertical beam 3 outer face, and the second floor 2 is fixedly connected between two vertical beams 3 with the form of reinforcing bar.
Further, the first junction of floor 1 between vertical beam 3 and the plate wing 4 is the one in plane or curved surface.
Further, the span that the quantity of the first floor 1 can be suitable for according to double T version regulates, and can be controlled in 6-9.
Further, the quantity of the second floor 2 is two, between distance controlling at 8-12m.
The advantage that the present invention has and good effect are: two class floors effectively can strengthen the pulling force that rises of T plate, and increase the span of T plate, make the longest span reaching 33 meters of product, can reach 4 layers, and every cubic metre can load-bearing 3-5 ton.The present invention is a kind of bearing type T plate, can build without post in construction machines factory building, exhibition room, hall etc.Traditional double T plate base strengthens the wide of T muscle and height, for a change rises and draw data, making by design parameters fixed point selecting on stress material, belonging to domestic advanced technology.

Detailed description of the invention
A kind of large-span prestressed load-bearing reinforcement concrete double T plate cross section is as Fig. 2, and it is integral prefabricated forming, and structure comprises the first floor 1, second floor 2, vertical beam 3, the plate wing 4, top board 5, suspension ring 6.Wherein two vertical beams 3 and the second floor 2 all integral prefabricated in punching block, built-in reinforcing bar.Vertical beam 3 is fixedly connected on below top board 5, and joining place is triangle, and this just constitutes the basic structure of T plate.Be fixedly connected with suspension ring 6 respectively in the corner of top board 5, be used for mobile T plate.First floor 1 is fixedly connected on the plate wing 4 side, and the first floor 1 inner side end is fixedly connected with both sides vertical beam 3 outer face.The floor of such setting can play the effect of reinforcing T plate, makes it have more crushing resistance and high strength.Second floor 2 is fixedly connected between two vertical beams with the form of reinforcing bar, and so not only again increase the intensity of T plate, the T plate also for realizing large span provides possibility.The reinforcing of double floor makes this reality invent more firm, durable, safety.
Adopt this T plate concrete prefabricated, ensure that product has height resistance to compression, good durability, wide region intensity, feature with low cost.The combination of concrete and rebar is more conducive to this product.Reinforcing bar and concrete have approximately uniform linear expansion coeffcient, can not produce excessive stress by environment difference.Secondly have good adhesion stress between reinforcing bar and concrete, the surface of reinforcing bar is also processed to spaced rib or floor to improve the mechanical snap between concrete and rebar.
Above embodiments of the invention have been described in detail, but described content being only preferred embodiment of the present invention, can not being considered to for limiting practical range of the present invention.All equalizations done according to the scope of the invention change and improve, and all should still belong within this patent covering scope.
